Description

The present invention relates to a sediment crusher that crushes sediment deposited in a groove such as a folded plate roof.

Conventionally, various techniques for cleaning the outer surface of a building exposed to the external environment have been proposed. Specifically, dust, rice husks, weeds, paper scraps, rain and other scattered matter can accumulate on the roof that covers the upper part of the building. The durability of the roof may decrease due to an increase in the load applied to the roof due to the accumulation of dust or the like on the roof. Therefore, an apparatus for removing deposits by cleaning the roof has been proposed for the purpose of suppressing a decrease in the durability of the roof (see, for example, Patent Document 1).

The upper cover 511 and the lower cover 512 are made of, for example, resin. Further, the upper cover 511 and the lower cover 512 may be transparent or translucent.

By providing the trolley 100 with the first cover 510, it is possible to prevent foreign matter from entering the space where the crushing device 200 is provided. Thereby, it is possible to prevent the crushing device 200 from failing.

Further, the upper cover 511 can be rotated about an axis along the left-right direction which is a connecting portion with the frame member 31c, and a handle 513 is provided at the rear portion of the upper surface portion of the upper cover 511. Therefore, the operator can open the opening defined by the frame members 31c, 31e, 31f, 31g by rotating the upper cover 511 using the handle 513. Thereby, the maintenance of the crushing device 200 and the posture adjustment of the crushing device 200 can be easily performed.

The second cover 520 is a cover that covers the space where the crushing device 200 is provided from behind. For example, the second cover 520 extends downward from the rear of the base 30. Specifically, the second cover 520 is attached to the frame member 31e or a bracket provided on the frame member 31e. The left-right dimension of the second cover 520 corresponds to the dimension of the space where the crushing device 200 is provided, and corresponds to, for example, the left-right dimension of the frame member 31e. The vertical dimension of the second cover 520 may be, for example, a dimension such that the lower end portion of the second cover 520 can come into contact with the ground contact surface of the carriage 100.

The second cover 520 is made of resin, for example. Further, the second cover 520 is, for example, a flexible sheet-like member.

By providing the trolley 100 with the second cover 520, it is possible to shield between the crushing device 200 and the worker located behind the trolley 100. As a result, it is possible to prevent the deposit S10, which is crushed by the crushing device 200 and scattered rearward, from colliding with the operator located behind the trolley 100.

The storage unit 530 stores tools used by the operator in the crushing operation. For example, the storage portion 530 is connected to the frame member 31c and is provided between the frame member 31b and the frame member 31c below the base portion 30. Thereby, the tools used in the crushing work can be moved together with the trolley 100.

The air gun 540 is a device that injects compressed air. Specifically, the air gun 540 is used for removing foreign matter adhering to each portion of the sediment crusher 1. For example, the air gun 540 is stored in the storage unit 530 in a state of being connected to the air tube C10. Thereby, for example, the foreign matter adhering to each portion of the sediment crusher 1 during the crushing operation can be appropriately removed.

The non-slip member 550 is provided so as to be externally fitted to the outer peripheral portion of the gripped portion 62 of the operating portion 60, and is a member for suppressing the hand of the operator who grips the gripped portion 62 from slipping. The outer surface of the non-slip member 550 has a large coefficient of friction as compared with the outer surface of the gripped portion 62. As a result, it is possible to prevent the hand of the operator who grips the gripped portion 62 from slipping.

The examples of the components that can be added to the sediment crusher 1 are not limited to the additional components described with reference to the sediment crusher 5 according to the application example.

For example, the sediment crusher 1 may be provided with a suction device that sucks and sends out the crushed sediment S10. Specifically, the suction device includes an accumulation portion for collecting and temporarily accumulating the crushed sediment S10, and a suction hose connected to the accumulation portion. The accumulation part is provided behind the crusher 200 of the sediment crusher 1 and has an opening. The suction hose connects the accumulating portion and the accommodating portion provided on the ground and accommodating the deposit S10. The crushed sediment S10 is sucked into the suction hose from the accumulation part side, and is sent out to the accommodating part on the ground through the suction hose.

Further, for example, the sediment crusher 1 may be provided with a detection unit for detecting that the sediment crusher 1 has reached the end of the folded plate roof 910 and a notification unit for notifying the detection result by the detection unit. good. The detection unit can be realized by, for example, a sensor provided in the front portion of the sediment crusher 1 and capable of detecting the presence or absence of an object within the detection range below the detection unit. The notification unit may be, for example, a sound output device that outputs sound according to the detection result, or a display device such as a lamp that emits light according to the detection result.

Further, for example, the sediment crusher 1 may be provided with a width direction moving mechanism that moves in the width direction of the groove G10. As a result, after the crushing work for the groove G10 is completed, the sediment crusher 1 can be moved to another groove G10 for which the crushing work has not been completed. The width direction moving mechanism is realized by, for example, a movable arm that can move the carriage 100 and the crushing device 200 in the width direction of the groove portion G10 beyond the convex portion between the adjacent groove portions G10 while supporting the own weight of the sediment crusher 1. Can be done. Further, when the folded plate roof 910 is provided with a structure that protrudes upward from the upper surface of the folded plate roof 910 and extends along the width direction of the groove portion G10, the width direction moving mechanism is, for example, the groove portion along the structure. It can be realized by a mechanism that can move in the width direction of G10.

<2. Operation of sediment crusher>
Subsequently, the operation of the sediment crusher 1 according to the present embodiment will be described with reference to FIGS. 8 to 13.

First, the flow of the crushing work using the sediment crusher 1 according to the present embodiment will be described with reference to FIGS. 8 to 10.

8 to 10 are explanatory views showing an example of a crushing operation using the sediment crusher 1 according to the present embodiment.

In the crushing work using the sediment crusher 1, the worker U10 first moves the trolley 100 along the groove G10 by pushing the trolley 100 forward while grasping the gripped portion 62 of the operating portion 60. Let me. At this time, for example, as shown in FIG. 8, the operator U10 is gripping the gripped portion 62, but is not gripping the lever C30. Therefore, the crusher 200 is not driven.

The worker U10 moves the trolley 100 to a position where the deposit S10 exists below the crushing device 200. For example, in the example shown in FIG. 8, since there is no deposit S10 below the crusher 200, the worker U10 moves the trolley 100 forward. Then, as in the example shown in FIG. 9, when the trolley 100 reaches the position where the deposit S10 exists below the crushing device 200, the worker U10 stops the movement of the trolley 100.

Such an operation of traveling the carriage 100 along the groove G10 is realized by providing the sediment crusher 1 with a traveling mechanism 110.

Next, the operator U10 further grips the lever C30 while gripping the gripped portion 62. For example, as shown in FIG. 9, when the lever C30 is gripped by the operator U10, the crushing device 200 is driven and the rotation of the wire brush 210 is started.

Next, the operator U10 lowers the crushing device 200 by pushing the operation unit 60 downward while grasping the gripped portion 62 and the lever C30. When the operating unit 60 is pushed downward, for example, as shown in FIG. 10, the spring 50 contracts to lower the rear portion of the base 30. At this time, the posture of the base 30 rotates with the front wheel 11 as a fulcrum. As a result, the crushing device 200 descends in a driven state. Then, as shown in FIG. 10, the outer peripheral portion of the wire brush 210 that is rotationally driven is pressed against the deposit S10, so that the deposit S10 is crushed.

After the crushing of the deposit S10 is completed, the worker U10 stops pushing the operation unit 60 downward, and the restoring force of the spring 50 causes the crushing device 200 to rise together with the base 30. As a result, the posture of the dolly 100 returns to, for example, the posture shown in FIG.

Such an operation of moving the crusher 200 up and down with respect to the ground plane of the carriage 100 is realized by providing the deposit crusher 1 with a vertical movement support mechanism 120.

Subsequently, with reference to FIG. 11, adjustment of the attachment angle of the crusher 200 to the carriage 100 around the axis along the front-rear direction in the sediment crusher 1 according to the present embodiment will be described.

FIG. 11 is an explanatory diagram for explaining the correspondence between the attachment angle of the crushing device 200 to the carriage 100 around the axis along the front-rear direction and the crushed portion in the sediment S10.

The groove G10 is formed including, for example, a bottom surface and a pair of side surfaces inclined with respect to the bottom surface. In that case, in the crushing operation, specifically, as shown in FIG. 11, first, the side portion of the wire brush 210 is along one side surface of the groove portion G10 (for example, the side portion of the wire brush 210 is the groove portion G10. With the mounting angle around the axis along the anteroposterior direction of the crusher 200 adjusted so as to be parallel to one side surface), the wire brush 210 is placed near one side surface of the groove G10 in the deposit S10. It is pressed. As a result, the portion of the deposit S10 fixed to one side surface of the groove G10 is appropriately crushed.

Next, the side portion of the wire brush 210 is along the other side surface of the groove portion G10 (for example, the side portion of the wire brush 210 is parallel to the other side surface of the groove portion G10) along the front-rear direction of the crushing device 200. With the mounting angle around the axis adjusted, the wire brush 210 is pressed against a portion of the deposit S10 near the other side surface of the groove G10. As a result, the portion of the deposit S10 fixed to the other side surface of the groove G10 is appropriately crushed.

Next, the crushing device 200 is attached around the axis along the front-rear direction so that the outer peripheral portion of the wire brush 210 faces the bottom surface of the groove portion G10 (for example, the side portion of the wire brush 210 is orthogonal to the bottom surface of the groove portion G10). With the angle adjusted, the wire brush 210 is pressed against the portion of the deposit S10 near the bottom surface of the groove G10. Thereby, the portion of the deposit S10 fixed to the bottom surface of the groove G10 is appropriately crushed.

In this way, while appropriately adjusting the mounting angle around the axis along the front-rear direction of the crushing device 200, the sediment to be crushed corresponding to the mounting angle is crushed in order in the sediment S10, thereby depositing the deposit in the groove G10. S10 can be appropriately crushed. Further, by appropriately adjusting the mounting angle around the axis of the crushing device 200 along the front-rear direction according to the shape of the groove portion G10, the deposit S10 can be appropriately crushed according to the shape of the groove portion G10.

It should be noted that between a plurality of crushing devices 200 provided along the traveling direction of the trolley 100 (for example, the crushing device 200 on the left front side and the crushing device 200 on the left rear side), the trolley 100 is axially oriented along the front-rear direction. The mounting angles may be different from each other. For example, the mounting angle around the axis of the crushing device 200 on the left front side in the front-rear direction is adjusted so that the side portion of the wire brush 210 is along one side surface of the groove portion G10. On the other hand, the mounting angle around the axis of the crushing device 200 on the left rear side in the front-rear direction is adjusted so that the side portion of the wire brush 210 is along the other side surface of the groove portion G10. In that case, in the crushing operation, both one side surface of the groove G10 and the portion in the vicinity of the other side surface of the sediment S10 are appropriate without adjusting the mounting angle around the axis along the front-rear direction of the crushing device 200. Can be crushed into. Therefore, in the crushing work for each groove G10, the number of adjustments of the mounting angle around the axis along the front-rear direction of the crushing device 200 can be reduced.

Such adjustment of the mounting angle around the axis along the front-rear direction of the crusher 200 is realized by providing the sediment crusher 1 with the first adjusting mechanism 130.

Subsequently, with reference to FIG. 12, the adjustment of the attachment angle of the crusher 200 to the carriage 100 around the axis along the vertical direction in the sediment crusher 1 according to the present embodiment will be described.

FIG. 12 is an explanatory view showing an example of a state in which the direction of the rotation axis of the wire brush 210 is aligned with the left-right direction and the attachment posture of the crushing device 200 to the carriage 100 is adjusted around the axis along the vertical direction. ..

As shown in FIG. 12, the wire brush in the deposit S10 is formed by adjusting the mounting angle around the axis of the crushing device 200 along the vertical direction so that the direction of the rotation axis of the wire brush 210 intersects the left-right direction. The region where 210 can be pressed can be expanded in the width direction of the groove G10. Therefore, the deposit S10 can be appropriately crushed according to the width of the groove G10 by appropriately adjusting the mounting angle around the axis of the crushing device 200 along the vertical direction according to the width of the groove G10.

Such adjustment of the mounting angle around the axis along the vertical direction of the crusher 200 is realized by providing the sediment crusher 1 with the second adjusting mechanism 140.

Subsequently, with reference to FIG. 13, the axial rotation operation of the front support portion 10 and the base portion 30 in the sediment crusher 1 according to the present embodiment along the relative front-rear direction will be described.

FIG. 13 is an explanatory view showing an example of the posture of the base portion 30 when the direction of the rotation axis of the front wheel 11 is tilted with respect to the left-right direction.

The upper surface of the deposit S10 deposited in the groove G10 is not always flat. For example, as shown in FIG. 13, the upper surface of the deposit S10 may be inclined along the width direction of the groove G10 so as to become higher from the left side to the right side. In the sediment crusher 1, as described above, the front wheel 11 is specifically located in front of the crusher 200. Therefore, the front wheels 11 may be located on the undulating deposit S10 before it is crushed.

Here, in the sediment crusher 1, as described above, the base portion 30 is rotatably supported around the axis along the front-rear direction by the front support portion 10. Therefore, for example, as shown in FIG. 13, even when the direction of the rotation axis of the front wheel 11 is tilted with respect to the left-right direction, it is the same as the case where the direction of the rotation axis of the front wheel 11 coincides with the left-right direction. The posture of the base 30 can be maintained horizontally. Thereby, the posture of the crusher 200 can be maintained in the same posture as when the upper surface of the deposit S10 is flat. Further, the worker U10 applies a rotational force around the axis along the front-rear direction to the base portion 30 via the operation portion 60, so that the front wheel 11 is in contact with the upper surface of the deposit S10 or the like. The posture around the axis along the front-rear direction of the base 30 can be appropriately adjusted.

Such an axial rotation operation along the relative front-rear direction between the front support portion 10 and the base portion 30 is realized by providing the sediment crusher 1 with a rotation support mechanism 150.

<3. Effect of sediment crusher>
Subsequently, the effect of the sediment crusher 1 according to the present embodiment will be described.

The deposit crusher 1 according to the present embodiment includes a trolley 100 having a traveling mechanism 110 capable of traveling along the groove G10, and a crusher 200 attached to the trolley 100 and crushing the deposit S10 deposited on the groove G10. Be prepared. Further, the trolley 100 is provided with a vertical movement support mechanism 120 that movably supports the crushing device 200 with respect to the ground plane of the trolley 100. As a result, the worker U10 can efficiently move the trolley 100 to the position where the deposit S10 to be crushed exists in the groove G10 by moving the trolley 100 along the groove G10. Further, the worker U10 can efficiently crush the sediment S10 at the position where the sediment S10 to be crushed exists by moving the crushing device 200 up and down with respect to the ground plane of the trolley 100. Therefore, the deposit S10 deposited in the groove G10 such as the folded plate roof 910 can be efficiently crushed. Therefore, the work of removing the deposit S10 can be made more efficient.

Further, in the sediment crusher 1 according to the present embodiment, the vertical movement support mechanism 120 has a base portion 30 to which the crushing device 200 is attached, a spring 50 as an elastic member, and elasticity that supports the base portion 30 via the elastic member. It may include a rear support portion 20 corresponding to the support portion. As described above, it is effective to support the crushing device 200 with respect to the ground plane of the carriage 100 so as to be vertically movable by the vertical movement support mechanism 120 including the base portion 30, the elastic member and the elastic support portion. Will be realized.

Further, in the sediment crusher 1 according to the present embodiment, the elastic support portion may be the rear support portion 20 that supports the rear portion of the base portion 30. Further, an operating portion 60 that protrudes vertically upward with respect to the base portion 30 and is gripped by an operator can be attached to the rear portion of the base portion 30. As a result, the worker U10 who operates the trolley 100 while holding the operation unit 60 can easily lower the crushing device 200 by pushing the operation unit 60 downward.

Further, in the sediment crusher 1 according to the present embodiment, the crusher 200 includes a wire brush 210 that crushes the deposit S10 by being rotationally driven with the outer peripheral portion pressed against the deposit S10. obtain. Here, for example, when the grindstone of the grinder is pressed against the deposit S10 to crush the deposit S10, it is difficult to properly crush the portion of the deposit S10 fixed to the surface of the groove G10. Furthermore, the grindstone is likely to be clogged. On the other hand, by using the wire brush 210 for crushing the deposit S10, such a problem can be suppressed, so that the deposit S10 can be crushed more efficiently.

Further, the sediment crusher 1 according to the present embodiment may include a first adjusting mechanism 130 capable of adjusting the attachment posture of the crushing device 200 to the trolley 100 around the axis along the traveling direction of the trolley 100. As a result, the crushed portion corresponding to the mounting angle of the sediment S10 can be crushed in order while appropriately adjusting the mounting angle of the crushing device 200 around the axis along the traveling direction of the trolley 100. Therefore, the deposit S10 deposited in the groove G10 can be appropriately crushed. Further, the deposit S10 is appropriately crushed according to the shape of the groove G10 by appropriately adjusting the mounting angle around the axis of the crusher 200 along the traveling direction of the trolley 100 according to the shape of the groove G10. Can be done.

Further, the sediment crusher 1 according to the present embodiment includes a second adjusting mechanism 140 capable of adjusting the attachment posture of the crushing device 200 to the trolley 100 around the axis along the direction intersecting the ground plane of the trolley 100. obtain. Thereby, by adjusting the mounting angle around the axis of the crushing device 200 along the direction intersecting the ground plane of the carriage 100, the region where the wire brush 210 can be pressed in the deposit S10 is defined in the width direction of the groove G10. Can be expanded. Therefore, the deposit S10 is appropriately adjusted according to the width of the groove G10 by appropriately adjusting the mounting angle around the axis of the crushing device 200 along the direction intersecting the ground plane of the carriage 100 according to the width of the groove G10. Can be crushed into.

Further, in the sediment crusher 1 according to the present embodiment, the crusher 200 can be driven by air pressure. Here, the sediment crusher 1 may be provided with a device driven by air pressure such as an air gun 540 or a suction device. Therefore, by driving the crusher 200 by air pressure, the drive source can be unified among the plurality of devices provided in the sediment crusher 1, so that different drive sources can be used among the plurality of devices. The number of parts in the sediment crusher 1 can be reduced as compared with the case where the sediment crusher 1 is used. Further, for example, when the crusher 200 is driven by an electric motor, it may be necessary to mount a relatively large electric motor on the sediment crusher 1 in order to secure the driving force applied to the crusher 200. On the other hand, when the crusher 200 is driven by air pressure, an air pressure supply source can be installed outside the sediment crusher 1, so that an increase in the weight of the sediment crusher 1 can be suppressed.

Further, in the sediment crusher 1 according to the present embodiment, the width of the wire brush 210 may be a dimension corresponding to the width of the bottom surface of the groove portion G10. Thereby, the portion of the deposit S10 fixed to the bottom surface of the groove G10 can be appropriately crushed as compared with the case where the width of the wire brush 210 is excessively long compared to the width of the bottom surface of the groove G10. Further, the number of times the wire brush 210 is pressed against the deposit S10 in the crushing operation can be reduced as compared with the case where the width of the wire brush 210 is excessively short as compared with the width of the bottom surface of the groove portion G10. Therefore, the sediment S10 can be crushed more efficiently.

Further, in the sediment crusher 1 according to the present embodiment, a plurality of crushers 200 may be provided along the traveling direction of the carriage 100. Further, among the plurality of crushing devices 200 provided along the traveling direction of the trolley 100, the attachment angles of the trolley 100 to the trolley 100 around the axis along the traveling direction may be different from each other. As a result, it is possible to appropriately crush a plurality of crushed points in the sediment S10 without adjusting the mounting angle around the axis of the crushing device 200 along the traveling direction of the trolley 100. Therefore, in the crushing work, it is possible to reduce the number of adjustments of the mounting angle around the axis of the crushing device 200 along the traveling direction of the trolley 100.

Further, in the sediment crusher 1 according to the present embodiment, a plurality of crushers 200 may be provided along the width direction of the groove G10. Further, the plurality of crushing devices 200 provided along the width direction of the groove portion G10 may be located in different groove portions G10. As a result, the sediment S10 can be crushed in parallel with respect to the plurality of groove portions G10 arranged side by side with each other, so that the sediment S10 can be crushed more efficiently. Further, for example, when two crushers 200 are arranged side by side along the width direction of the groove G10, the number of crushers 200 provided along the width direction of the groove G10 is singular, as compared with the case where the number of crushers 200 is singular. The posture of the crusher 1 can be stabilized.

Further, in the sediment crusher 1 according to the present embodiment, the trolley 100 may be provided with a rotation support mechanism 150 that rotatably supports the crusher 200 around the axis along the traveling direction of the trolley 100. As a result, even when the upper surface of the deposit S10 deposited on the groove G10 is inclined along the width direction of the groove G10, the posture of the crusher 200 may be changed to the case where the upper surface of the deposit S10 is flat. It can be maintained in a similar position. Therefore, the sediment S10 can be crushed more efficiently.

Further, in the sediment crusher 1 according to the present embodiment, the rotation support mechanism 150 rotatably supports the base 30 to which the crusher 200 is attached and the base 30 around the axis along the traveling direction of the carriage 100. It may include a front support portion 10 corresponding to the rotation support portion to be used. As described above, since the rotation support mechanism 150 includes the base portion 30 and the rotation support portion, it is effective to rotatably support the crushing device 200 around the axis along the traveling direction of the carriage 100. Will be realized.

Further, in the sediment crusher 1 according to the present embodiment, the rotation support portion may be a front support portion 10 having a front wheel 11 and supporting the front portion of the base portion 30. Further, an operating portion 60 that protrudes vertically upward with respect to the base portion 30 and is gripped by an operator can be attached to the rear portion of the base portion 30. As a result, the worker U10 who operates the trolley 100 while gripping the operation unit 60 causes the base portion 30 to act on the base portion 30 with rotational power around the axis along the traveling direction of the trolley 100 via the operation unit 60. With the front wheels 11 grounded on the upper surface of the deposit S10 or the like, the axial posture of the base 30 along the traveling direction of the carriage 100 can be appropriately adjusted.
