Description

The present invention relates to an auxiliary tool for a float type water level gauge used when inspecting or cleaning a float type water level gauge.

A float type water level gauge is known as one of devices for accurately measuring the water level of a river or a dam (see, for example, Patent Document 1). In this float type water level gauge, a weight is arranged at one end of a wire hung on a pulley (pulley), and a float (floating body) is arranged at the other end of the wire. Then, when the float floats on the water and the water level changes while the wire is stretched by the weight, the float moves up and down along with the change, and the water level is measured based on the position of the float.

Further, a wave breaker is arranged from the water surface to the water, and a wire, a weight and a float are arranged in the breakwater. Further, a hut-shaped storage (mount) is provided above the breakwater and covering the pulley.

By the way, when inspecting or cleaning the float type water level gauge as described above, it is conventionally necessary for an operator to enter the containment chamber and pull up the weight or float. In other words, in a narrow storage room, the wires must be pulled up to pull up the weights and floats for inspection, and the wires must be pulled down to lower the weights and floats, which puts a heavy burden on the workers. It was.

In addition, since the work must be performed in a narrow storage room in a bad posture, the following problems may occur. First, when the water level measurement range is wide (the wire is long), the wire must be pulled up or down for a long time, and there is a risk that the wire may be dropped on the way due to fatigue. Second, there was a risk that the wire would come off the pulley due to the sudden pulling up and down of the wire. Third, if the wire is pulled up or down while the wire is in contact with the upper end edge (haunch portion) of the breakwater tube, the wire may be worn or damaged.

Therefore, it is an object of the present invention to provide a float type water level gauge assisting tool that reduces the burden on the operator and enables the wire to be pulled up appropriately.

In order to solve the above problems, the invention of claim 1 is the weight of a float type water level gauge in which a weight is arranged at one end of a wire hung on a pulley and a float is arranged at the other end of the wire. Alternatively, a float-type water level gauge auxiliary tool for pulling up the float, a temporary fixing member temporarily fixed to an external member around the float-type water level gauge, and an auxiliary pulley arranged on the temporary fixing member. , The temporary fixing member is temporarily fixed to the external member, and the wire is hung on the auxiliary pulley and pulled out in the lateral direction, whereby the weight or the float is pulled up.

According to the present invention, the temporary fixing member is temporarily fixed to the external member, and one end side of the wire is hung on the auxiliary pulley and pulled out laterally to the outside, whereby the weight is pulled up and the other end side of the wire is used as the auxiliary pulley. The float can be pulled up by hanging it and pulling it outward in the lateral direction. After that, the temporary fixing member is temporarily fixed to the external member, and one end side of the wire is hung on the auxiliary pulley and pushed out laterally inward (the pulley side), so that the weight is pulled down and the other end side of the wire becomes the auxiliary pulley. The float is pulled down by hanging it and pushing it inward in the horizontal direction.

The invention of claim 2 is the float type water level gauge auxiliary tool according to claim 1, wherein the temporary fixing member is provided with a rod-shaped support member connected to the temporary fixing member, and the floor body is used as the external member. By arranging the support member on the floor body and holding the support member, the temporary fixing member is temporarily fixed to the floor body.

The invention of claim 3 is characterized in that, in the float type water level gauge auxiliary tool according to claim 2 , the support member has an adjustable protrusion angle from the temporary fixing member.

According to a fourth aspect of the present invention, in the float type water level gauge auxiliary tool according to the first aspect, the temporary fixing member can be temporarily fixed by using the storage chamber covering the float type water level gauge as the external member. , Characterized by that.

According to the first aspect of the present invention, the weight or the float can be pulled up by hanging the wire on the auxiliary pulley and pulling it out laterally. In other words, since the worker only has to pull out the wire from the outside of the vault without entering the vault, it is possible to easily pull up the wire without imposing a heavy burden on the worker. Become.

Since the work can be performed in a large space outside the containment chamber, it is possible to properly pull up the wire by using the whole body in a comfortable posture. As a result, for example, even when the wire must be pulled up or down for a long time, fatigue is reduced, and it is possible to prevent or suppress the wire from falling on the way. Further, by rapidly pulling up or pulling down the wire, it is possible to prevent or suppress the wire from coming off the pulley. Further, since the wire is supported by the auxiliary pulley in the middle of pulling up or pulling down, it is possible to prevent or suppress the wire from coming into contact with the upper end edge of the breakwater tube and being worn or damaged.

According to the second aspect of the present invention, the temporary fixing member is temporarily fixed to the floor body (external member) simply by arranging the temporary fixing member on the floor body and holding the rod-shaped support member by hand or the like. Regardless of the environment (even if it cannot be temporarily fixed to an external member such as a storage cabinet), the temporary fixing member can be temporarily fixed to the external member reliably and easily. As a result, regardless of the surrounding environment, it is possible to reduce the burden on the operator and properly pull up the wire. Further, since the structure is as simple as connecting the rod-shaped support member to the temporary fixing member, it can be manufactured easily and at low cost, and maintenance and handling are easy.

According to the third aspect of the present invention, since the protrusion angle of the support member with respect to the temporary fixing member can be adjusted, the support member can be more appropriately and easily adjusted by adjusting the protrusion angle according to the surrounding environment, the height of the worker, and the like. Can be held. As a result, the burden on the operator can be further reduced, and the wire can be properly pulled up.

According to the invention of claim 4, since the temporary fixing member can be temporarily fixed to the storage of the float type water level gauge, by temporarily fixing the temporary fixing member to the storage, the operator can temporarily fix the temporary fixing member, that is, the auxiliary tool. There is no need to hold. Therefore, the burden on the operator can be further reduced, and the wire can be pulled up appropriately.

As shown in FIG. 4, the storage 110 is arranged on the floor 120 in a substantially rectangular parallelepiped shape, and the surface side 110a is opened when the door 111 is opened. Further, an opening 120a is provided in a portion of the floor body 120 (directly below the storage 110) in which the storage 110 is arranged, and a wave breaker 103 is arranged through the opening 120a.

The float type water level gauge auxiliary tool 1 mainly includes a temporary fixing member 2, an auxiliary pulley 3, and a support member 4.

The temporary fixing member 2 is a member that is temporarily fixed to an external member around the float type water level gauge 100, and in this embodiment, the floor body 120 is temporarily fixed as an external member. That is, as shown in FIGS. 2 and 3, the rod-shaped body includes a horizontally extending horizontal portion 21 and an inclined portion 22 extending diagonally downward from one end of the horizontal portion 21.

Further, on the lower surface of the horizontal portion 21, a stopper 23 having an L-shaped cross section and a rod shape is arranged so as to be orthogonal to the horizontal portion 21 and to extend one side perpendicular to the horizontal portion 21. .. Then, as shown in FIG. 1, the inclined portion 22, that is, the auxiliary pulley 3 described later is on the wire 105 side in a state where the stopper 23 is applied to the edge of the opening 120a of the floor body 120 and the horizontal portion 21 is arranged on the floor body 120. The shape of the temporary fixing member 2 is set so as to project to the horizontal.

The auxiliary pulley 3 is a pulley that is arranged on the temporary fixing member 2 and on which the wire 105 can be hung. That is, the wire 105 is hung on the upper surface of the inclined portion 22 of the temporary fixing member 2 in a state where the rotation axis thereof is orthogonal to the axis of the temporary fixing member 2 and the temporary fixing member 2 is arranged on the floor body 120 as described above. It is arranged so as to be. Specifically, in this embodiment, by arranging the temporary fixing member 2 on the floor body 120, the auxiliary pulley 3 comes into contact with the wire 105, and the wire 105 can be hung on the auxiliary pulley 3.

Then, in a state where the temporary fixing member 2 is temporarily fixed to the floor body 120 as described later, as shown in FIG. 1, the wire 105 is hung on the auxiliary pulley 3 and laterally outward (outside the storage 110). By pulling out, the weight 101 or the float 102 is pulled up. Similarly, the weight 101 or the float 102 is pulled down by hanging the pulled out wire 105 on the auxiliary pulley 3 and pushing it laterally inward (inside the storage 110).

The support member 4 is a rod-shaped member connected to the temporary fixing member 2, and the protrusion angle from the temporary fixing member 2 can be adjusted. In this embodiment, the temporary fixing member 2 is interposed via the connecting plate 5. Is linked to. That is, as shown in FIG. 2, the connecting plate 5 is a fan-shaped flat plate having a temperature of approximately 90 °, the plate surface thereof is parallel to the axis of the temporary fixing member 2, and the horizontal side is the lower surface and the surface of the horizontal portion 21. It is arranged at the other end of the horizontal portion 21 so as to be one. Further, an arc-shaped slit (long hole) 51 centered on a right-angled portion is formed on the plate surface of the connecting plate 5.

Then, one end of the long main body 41 of the support member 4 is rotatably connected to the right-angled portion of the connecting plate 5 via the rotating shaft 42. As a result, the main body 41 extends parallel to the axis of the horizontal portion 21 of the temporary fixing member 2, and the main body 41 rotates around the rotation axis 42 orthogonal to the axis of the horizontal portion 21, and the protrusion angle from the horizontal portion 21. (Angle with respect to the horizontal) can be adjusted.

Further, a screw hole is formed on the rotation shaft 42 side of the main body 41, and the main body 41 is fixed to the connecting plate 5 (rotation is stopped) by inserting the set screw 43 into the slit 51 and tightening the set screw 43 into the screw hole. It has become like. On the other hand, at the other end of the main body 41, a handle 44 extending perpendicular to the main body 41 is arranged. Then, as shown in FIG. 1, the temporary fixing member 2 is temporarily fixed to the floor body 120 by arranging the horizontal portion 21 of the temporary fixing member 2 on the floor body 120 and holding the handle 44 of the support member 4. To.

Next, the usage, operation, and the like of the float type water level gauge auxiliary tool 1 having such a configuration will be described. Here, prior to the work, the protrusion angle of the support member 4 with respect to the temporary fixing member 2 is adjusted according to the surrounding environment, the height of the sub-worker M2, and the like. That is, the set screw 43 is loosened to rotate the main body 41 to a desired angle, and the set screw 43 is tightened to stop the main body 41 from rotating.

In order to pull up the weight 101 and the float 102 for inspection and cleaning, first, the door 111 of the storage 110 is opened, and as shown in FIG. 1, the temporary fixing member 2 is attached to the edge of the opening 120a of the floor body 120. The stopper 23 of the above is applied to place the horizontal portion 21 on the floor body 120, and the sub-operator M2 holds the handle 44 of the support member 4 to temporarily fix the temporary fixing member 2 to the floor body 120. As a result, the auxiliary pulley 3 protrudes to the wire 105 side, and the main operator M1 hangs one end side of the wire 105 (one wire 105 divided by the pulley 104) on the auxiliary pulley 3 and laterally outwards (anti-waveproof). The weight 101 is pulled up by pulling it out to the tube 103 side). At this time, the main worker M1 may pull out the wire 105 from the outside of the storage 110 to the outside of the storage 110 without entering the storage 110. Similarly, the float 102 is pulled up by hanging the other end side of the wire 105 (the other wire 105 divided by the pulley 104) from the outside of the storage 110 on the auxiliary pulley 3 and pulling it outward in the lateral direction.

Next, in order to pull down the weight 101 and the float 102 after the inspection and cleaning of the weight 101 and the float 102 are completed, first, the temporary fixing member 2 is temporarily fixed to the floor body 120 in the same manner as described above. Subsequently, the main operator M1 hangs one end side of the wire 105 on the auxiliary pulley 3 and pushes it laterally inward (toward the wave breaker 103 side) to pull down the weight 101. At this time, the main worker M1 may push the wire 105 from the outside of the storage 110 into the inside of the storage 110 without entering the storage 110. Similarly, the float 102 is pulled down by hanging the other end side of the wire 105 from the outside of the storage 110 on the auxiliary pulley 3 and pushing it laterally inward.

As described above, according to the float type water level gauge auxiliary tool 1, the weight 101 and the float 102 can be pulled up by hanging the wire 105 on the auxiliary pulley 3 and pulling it out in the lateral direction. That is, since the main worker M1 may pull out the wire 105 from the outside of the storage 110 without entering the storage 110, the wire 105 can be easily pulled out without imposing a heavy burden on the main worker M1. It is possible to raise the wire.

Since the work can be performed in a wide space outside the storage 110, it is possible to properly pull up the wire 105 by using the whole body in a comfortable posture. As a result, for example, even when the wire 105 has to be pulled up or down for a long time, fatigue is reduced, and it is possible to prevent or suppress the wire 105 from being dropped on the way. Further, by abruptly pulling up or pulling down the wire 105 so as not to cause fatigue, it is possible to prevent or suppress the wire 105 from coming off the pulley 104. Further, since the wire 105 is supported by the auxiliary pulley 3 during pulling up and down (because the auxiliary pulley 3 is located inside the opening 120a and the end edge of the breakwater pipe 103), the upper end of the breakwater pipe 103. It is possible to prevent or suppress the wire 105 from coming into contact with the edge and being worn or damaged.

Further, the temporary fixing member 2 is temporarily fixed to the floor body (external member) 120 simply by arranging the temporary fixing member 2 on the floor body 120 and holding the rod-shaped support member 4 by hand or the like. Therefore (because the floor always exists even when the temporary fixing member cannot be temporarily fixed to the external member such as the storage 110), the temporary fixing member 2 can be temporarily fixed to the external member reliably and easily. As a result, regardless of the surrounding environment, the burden on the operator can be reduced and the wire 105 can be properly pulled up. Further, since the structure is as simple as connecting the rod-shaped support member 4 to the temporary fixing member 2, it can be manufactured easily and at low cost, and can be easily maintained and handled.

Moreover, since the protrusion angle of the support member 4 with respect to the temporary fixing member 2 can be adjusted, the support member 4 can be held more appropriately and easily by adjusting the protrusion angle according to the surrounding environment, the height of the worker, and the like. Is possible. As a result, the burden on the operator can be further reduced, and the wire 105 can be properly pulled up.

It is set up. That is, the holding plates 61 and 62 are arranged in a strip shape, orthogonal to the horizontal portion 21, and so that the plate surface extends perpendicularly to the horizontal portion 21. Further, two temporary fixing screws 63 are screwed into the second holding plate 62 far from the auxiliary pulley 3.

On the other hand, as shown in FIG. 6, in the storage 110, the lower end edge 112 having an L-shaped cross section as shown in FIG. 7 is exposed at the lower part in a state where the door 111 is opened and the surface side 110a is opened. .. The lower end edge portion 112 is one side constituting the lower square frame of the storage 110, and the vertical portion 112a rises substantially vertically and the horizontal portion 112b extends substantially horizontally.

Further, the gap between the first holding plate 61 and the second holding plate 62 is set to be slightly larger than the thickness of the vertical portion 112a of the lower end edge portion 112. Then, by inserting the vertical portion 112a between the first holding plate 61 and the second holding plate 62 and tightening the temporary fixing screw 63, the temporary fixing member 2, that is, the float type water level gauge auxiliary tool 10 is accommodated. It is temporarily fixed to the lower end edge 112 of the storage 110. Further, in such a temporarily fixed state, the auxiliary pulley 3 comes into contact with the wire 105 and the wire 105 can be hung on the auxiliary pulley 3 as in the first embodiment.

According to such an embodiment, since the temporary fixing member 2 can be temporarily fixed to the storage 110 of the float type water level gauge 100, the worker can temporarily fix the temporary fixing member 2 to the storage 110. It is not necessary to hold the fixing member 2, that is, the float type water level gauge auxiliary tool 10. Therefore, the burden on the operator can be further reduced, and the wire 105 can be properly pulled up. Further, since it does not have a long support member 4, the whole is compact and easy to handle, transport, and store.

Although the embodiment of the present invention has been described above, the specific configuration is not limited to the above-described embodiment, and even if there is a design change or the like within a range that does not deviate from the gist of the present invention.
