Description

  BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a turning device for scraping a wall surface.

  When changing the shape or size of a concrete structure, a cutting operation called "rounding" may be performed. In general, cutting work on a concrete structure is manually performed by striking a chisel with an electric hammer or using an air cutter. However, with such a method, the burden on the worker is increased.

  In the past, in order to reduce the burden on workers in elevator repair work, etc., a concrete turning device has been proposed in which a cutter is provided in the elevator car and the concrete wall of the hoistway is cut with the cutter. (See, for example, Patent Document 1).

  Also, conventionally, the main body is pressed to the concrete surface by connecting a scatterer to the main body which gives impact and breaks the concrete surface to the main body, and suspending the main body with a wire which is inclined to be gradually separated from the concrete surface downward. There is also proposed a whistle device as described above (see, for example, Patent Document 2).

It is a front view which shows the state in which the rolling apparatus of FIG. 1 is installed in the wall surface. It is a schematic diagram which shows the state in which the winding apparatus of FIG. 1 is installed in the wall surface of the hoistway of an elevator.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
Embodiment 1
FIG. 1 is a front view showing a roasting apparatus according to Embodiment 1 of the present invention. Moreover, FIG. 2 is a side view which shows the rolling apparatus of FIG. Furthermore, FIG. 3 is a front view which shows the state in which the rolling apparatus of FIG. 1 is installed in the wall surface. The bending apparatus 1 is an apparatus for automatically scraping the wall surface 10 such as a concrete wall, for example. The folding device 1 includes a folding device body 2, a plurality of winches 3 provided in the folding device body 2, and a plurality of cord-like bodies 4 individually wound around the plurality of winches 3. Provided on a plurality of wall surface distance sensors 5 provided on the wall surface 10 side of the device body 2, a plurality of outer periphery distance sensors 6 provided on the outer peripheral portion of the bending device body 2, and on the bending device body 2 And a dust suction device 7 for sucking dust.

  As shown in FIG. 3, a plurality of anchor bolts 8 are fixed to the wall surface 10 as fixing portions. Each anchor bolt 8 is fixed around the cutting target range 11 preset on the wall surface 10. The cutting target range 11 is a range for specifying a portion on the wall surface 10 to be cut by the rolling device 1. Each anchor bolt 8 is connected with a cord 4 wound on a winch 3 respectively. In this example, four anchor bolts 8 are fixed to the wall surface 10. Moreover, in this example, four winches 3 are provided in the bending device body 2, and four cord-like bodies 4 wound around each winch 3 are individually connected to each anchor bolt 8. For example, a wire or a rope is used as the cord-like body 4.

  As shown in FIG. 3, the bending device main body 2 is in an antagonistic state in which the plurality of cord-like bodies 4 connected to the anchor bolts 8 attract the bending device main body 2. It is pressed against the wall 10 while maintaining its position. That is, the tension of the plurality of cord-like members 4 attracting the bending device body 2 antagonizes, so that the position of the bending device body 2 is maintained and the bending device body 2 is pressed against the wall surface 10. In FIG. 3, the winch 3 is not shown.

  Further, as shown in FIG. 1 and FIG. 2, the bending device main body 2 surrounds the periphery of the support housing 21, the cutting mechanism 22 provided on the support housing 21 and scraping the wall 10, and the cutting mechanism 22. And a surrounding frame 23 fixed to the support housing 21. In this example, as shown in FIG. 1, the external shape of each of the support housing 21 and the enclosure 23 when viewed from the wall surface 10 is rectangular.

  The cutting mechanism unit 22 has a cutter blade which is a cutting body, and a feeding unit for displacing the cutter blade with respect to the support housing 21 in the direction in which the distance between the cutter blade and the wall surface 10 changes (both of them Not shown). The cutter blade is rotatable about a rotation axis (not shown) disposed along the wall surface 10. The cutter blade cuts the wall surface 10 by rotating around the rotation axis. The feed unit has a feed motor for displacing the rotary shaft of the cutter blade. The feed unit feeds the cutter blade by displacing the rotation axis of the cutter blade in the depth direction in which the wall surface 10 is cut. Thereby, the feed amount of the cutter blade with respect to the support housing 21 can be adjusted.

  The turning device body 2 is disposed on the wall surface 10 in a state in which the enclosure 23 is pressed against the wall surface 10. The enclosure 23 may be made of, for example, an elastic material such as rubber, or may be made of a material such as metal or plastic. In this example, the enclosure 23 is made of rubber. Thereby, in this example, the enclosure frame 23 is elastically deformed by the enclosure frame 23 being pressed against the wall surface 10.

  Each winch 3 is provided on the surface of the support housing 21 opposite to the wall surface 10 side. Further, when the turning device main body 2 is viewed from the wall surface 10 side, each winch 3 is disposed around the cutting mechanism portion 22. In this example, each winch 3 is provided at the rectangular four corners of the support housing 21. Further, each winch 3 has a drum 31 around which the cord-like body 4 is wound, a winch motor 32 for rotating the drum 31, and a winch mounting portion 33 for supporting the drum 31 and the winch motor 32.

  The support housing 21 is provided with a plurality of mounting shafts 34. Each winch mounting portion 33 is individually attached to each mounting shaft 34. The turning device main body 2 is disposed with the axis of each mounting shaft 34 orthogonal to the wall surface 10. Each winch 3 is rotatable about the axis of the mounting shaft 34. Thereby, when the direction of tension of the cord-like body 4 wound around the drum 31 changes, the angle of the winch 3 with respect to the support housing 21 also changes in accordance with the direction of tension of the cord-like body 4.

  The winch 3 winds the cord-like body 4 around the drum 31 or feeds out the cord-like body from the drum 31 by rotating the drum 31 by the driving force of the winch motor 32. When the winch 3 winds up the cord 4, the length of the cord 4 between the winch 3 and the anchor bolt 8 becomes short. When the winch 3 delivers the cord 4, the length of the cord 4 between the winch 3 and the anchor bolt 8 becomes longer. The winding device main body 2 is pressed against the wall surface 10 by the respective winches 3 rolling up and pulling out the cord-like body 4 while maintaining the antagonistic state being pulled by the plurality of cord-like bodies 4 It can move on the wall surface 10.

  For example, when moving the bending apparatus body 2 upward, as shown in FIG. 3, among the four winches 3, two winches 3 located at the upper part of the support housing 21 wind the cord-like body 4, Two winches 3 located at the lower part of the support housing 21 draw out the cordlike body 4. As a result, the bending device body 2 moves upward on the wall surface 10 while maintaining the state of being pressed against the wall surface 10. Since the movement range of the turning device body 2 is limited within the range surrounded by the straight line connecting the anchor bolts 8, the position of each anchor bolt 8 is determined in accordance with the shape and size of the cutting target range 11 There is.

  A plurality of (two in this example) suction ports 71 are provided on the surface of the support housing 21 on the wall surface 10 side. Each suction port 71 is located inside the enclosure 23 when the turning device body 2 is viewed from the wall surface 10 side. The dust suction apparatus 7 has a plurality of (two in this example) suction pipes 72 individually connected to the suction ports 71 and a common suction apparatus main body 73 to which the respective suction pipes 72 are connected. There is.

  The suction device main body 73 has a tank provided on the opposite side of the wall surface 10 of the support housing 21 and a suction drive unit connected to the tank. Each suction pipe 72 is connected to the tank of the suction device main body 73. The suction device main body 73 generates suction force from the suction ports 71 to the tank by the suction operation of the suction drive unit. The suction drive unit of the suction device main body 73 may be attached to the tank, or may be disposed at a location away from the tank and connected to the tank via a hose or the like. Dust generated by cutting of the wall surface 10 by the cutting mechanism unit 22 is sucked by the suction ports 71 by the suction operation of the suction device main body 73. Since the cutting mechanism 22 and the suction ports 71 are surrounded by the enclosure 23, scattering of dust outside the main body 2 is suppressed.

  Each of the wall surface distance sensors 5 is provided on the surface of the support housing 21 on the wall surface 10 side, as shown in FIGS. 1 and 2. Each wall distance sensor 5 is disposed toward the wall 10. Thereby, each wall surface distance sensor 5 measures the distance from the wall surface distance sensor 5 to the wall surface 10. Furthermore, each wall surface distance sensor 5 is disposed around the cutting mechanism 22 when the turning device body 2 is viewed from the wall surface 10 side. In this example, as shown in FIG. 1, four wall surface distance sensors 5 are provided in the support housing 21. When the turning device main body 2 is viewed from the wall surface 10 side, the rectangular shape of the support housing 21 The wall surface distance sensors 5 are respectively disposed on the inner side of the enclosure 23 in correspondence with the four sides of.

  Each outer peripheral distance sensor 6 is provided on the outer peripheral surface of the support housing 21. Further, each outer periphery distance sensor 6 is disposed along the wall surface 10 toward the outside of the support housing 21. Thereby, each outer periphery distance sensor 6 measures the distance from the outer periphery distance sensor 6 to an obstacle present on the wall surface 10. In this example, eight outer periphery distance sensors 6 are provided in the support housing 21, and when the turning device main body 2 is viewed from the wall surface 10 side, outer peripheries of four rectangular corners of the support housing 21 Two outer peripheral distance sensors 6 are provided on the surface. Further, in this example, the directions of the two outer peripheral distance sensors 6 at the common corner of the support housing 21 are different from each other.

  The rotation device body 2 is provided with a control unit (not shown) that controls the operation of the rotation device 1. The control unit individually controls the operations of the cutting mechanism 22 and each winch 3. That is, the control unit controls the feed unit of the cutting mechanism unit 22 to adjust the feed amount of the cutter blade relative to the support housing 21, and individually controls the operation of each winch 3. The movement of the bending device body 2 is controlled. The turning device body 2 moves on the wall surface 10 within the cutting target range 11 while thinly cutting the wall surface 10 with a cutter blade. Moreover, the cutting of the wall surface 10 by the cutting mechanism 22 is performed by feeding the cutter blade of the cutting mechanism 22 little by little while reciprocating the reciprocating device main body 2 dividing the wall surface 10 a plurality of times, thereby achieving the target cutting depth It will be done until Dust generated by the cutting of the wall surface 10 is sucked from the suction ports 71 into the tank of the dust suction unit 7 by the suction operation of the dust suction unit 7.

  Information from each of the wall surface distance sensors 5 and each of the outer periphery distance sensors 6 is sent to the control unit. The control unit adjusts the feed amount of the cutter blade by controlling the feed unit of the cutting mechanism unit 22 based on the information from the wall surface distance sensors 5. This prevents the feed amount of the cutter blade from being too large or too small relative to the actual cutting depth. Further, the control unit individually controls the operation of each winch 3 based on the information from each outer periphery distance sensor 6.

  The control unit detects an obstacle when the distance measured by the outer peripheral distance sensor 6 becomes smaller than the set value. When the control unit detects an obstacle present on the wall 10 based on the information from the outer peripheral distance sensor 6, the control unit individually controls the operation of each winch 3 to avoid collision with the obstacle. The apparatus body 2 is moved. A battery is mounted on the bending device body 2. The power required for the operation of the roasting device 1 is supplied from the battery.

  Next, a procedure for scraping the wall 10 of the hoistway using the crawling device 1 in the elevator repair work will be described. FIG. 4 is a schematic view showing a state in which the folding apparatus 1 of FIG. 1 is installed on the wall surface 10 of the hoistway of the elevator. A car 81 and a counterweight 82 are suspended by a main rope 83 in the hoistway 80. The car 81 and the counterweight 82 move up and down in the hoistway 80 by the driving force of the hoisting machine 84 around which the main rope 83 is wound.

  When repair work of the elevator is to be performed, as shown in FIG. 3, the range to be cut by the turning device 1 is set in advance as the cutting range 11 on the wall surface 10 of the hoistway 80. Further, on the wall surface 10, a plurality of anchor bolts 8 are fixed in advance around the area 11 to be cut. In this state, the device main body 2 is installed on the wall surface 10 within the cutting target range 11.

  When installing the turning device main body 2 on the wall surface 10 within the cutting target range 11, first, with the enclosure 23 being in contact with the wall surface 10, each cord 4 of the turning device main body 2 is fixed to each anchor bolt 8. Connecting. Thereafter, a force is applied to each winch 3 in the direction in which the cords 4 are taken up, and tension is generated in each cord 4. As a result, the respective cord-like members 4 enter an antagonistic state in which the bending device main body 2 is drawn, and the position of the bending device main body 2 is maintained in a state where the enclosure 23 of the bending device main body 2 is pressed against the wall surface 10 . Thus, the turning device main body 2 is installed on the wall surface 10 within the cutting target range 11.

  After that, while the dust suction device 7 is operated by the control of the control unit and the feed amount of the cutter blade of the cutting mechanism unit 22 is adjusted, the winding and unwinding operations of the cord-like body 4 by each winch 3 are individualized To do. As a result, the cutting device 22 moves on the wall 10 while the cutting mechanism 22 cuts the wall 10. The adjustment of the feed amount of the cutter blade of the cutting mechanism unit 22 and the movement of the turning device body 2 are automatically controlled by the control program set in the control unit. The feed amount of the cutter blade is adjusted based on the detection results from the wall surface distance sensors 5. The turning device body 2 cuts the wall surface 10 little by little while repeating the reciprocating movement on the wall surface 10 a plurality of times, thereby cutting the wall surface 10 of the cutting target range 11 to a target depth.

  At this time, when the control unit detects an obstacle present on the wall surface 10 based on the information from each of the outer peripheral distance sensors 6, for example, a device for turning around the obstacle, such as a direction of moving backward with respect to the obstacle. The moving direction of the main body 2 is changed by the control of the control unit. When the dust suction device 7 is in operation, since the cutting mechanism 22 and the suction ports 71 are surrounded by the enclosure 23, the air pressure in the enclosure 23 becomes low, and the rotation device main body 2 to the wall 10 It becomes easy to maintain the pressed state of

  In such a winding apparatus 1, the winding apparatus main body 2 is pressed against the wall surface 10 by the plurality of cord-like bodies 4 drawing in the winding apparatus body 2. And by the operation of feeding out, the turning device main body 2 can be easily moved on the wall surface 10 while pressing the turning device main body 2 against the wall surface 10. As a result, the bending device body 2 can be automatically moved in all directions vertically and horizontally, and the entire wall surface 10 within the cutting target range 11 can be easily cut without repositioning the bending device body 2. Can. Therefore, the burden of work when scraping the wall 10 can be reduced. Further, for example, when the wall 10 of the hoistway 80 is scraped in the elevator repair work, the wall 10 may be scraped by the pivoting device 2 even while the elevator is in operation if the pivoting device 2 is installed on the wall 10. it can. Therefore, a long-term stop of the elevator due to the elevator repair work can be avoided.

  Further, since the feed amount of the cutter blade of the cutting mechanism portion 22 can be adjusted by the feeding portion, the wall surface 10 can be cut to a target depth while the wall surface 10 is thinly cut by the cutter blade. Thereby, the noise when scraping the wall surface 10 can be greatly reduced.

  In addition, a wall surface distance sensor 5 for measuring the distance to the wall surface 10 is provided in the bending device body 2, and the control unit of the bending device 1 is configured to cut the cutting mechanism 22 based on the information from the wall surface distance sensor 5. Since the feed amount of the cutter blade is controlled, it is possible to prevent the depth to which the wall surface 10 is cut from being too deep or too shallow than the target depth.

  Further, an outer peripheral distance sensor 6 for measuring the distance to the obstacle is provided in the turning device main body 2, and the control unit of the turning device 1 detects the distance from each winch 3 based on the information from the outer peripheral distance sensor 6. Since the operation is individually controlled, even if there is an obstacle on the wall 10, it is possible to avoid the collision of the bending device body 2 with the obstacle. Thereby, the wall surface 10 can be scraped more reliably.

  Further, since the dust suction device 7 for sucking dust is provided in the scattering device main body 2, it is possible to suppress scattering and diffusion of dust generated by scraping the wall surface 10.

  In the above example, although the cutter blade is used as a cutting body for cutting the wall surface 10, the present invention is not limited thereto. For example, even if a grinding stone or cutting stone of a grinder is used as a cutting body of the cutting mechanism portion 22 Good.

  In the above-mentioned example, although power supply to each of the cutting mechanism 22, the winches 3 and the dust suction device 7 is performed from the battery mounted on the main body 2, the cutting mechanism 22, each Power may be supplied to each of the winch 3 and the dust suction device 7 from an external power supply. For example, when the device body 2 is installed on the wall surface 10 of the elevator shaft 80 of the elevator, power may be supplied from the power supply facility installed in the shaft 80 to the device 1.

  In the above example, one cord-like body 4 is wound around one winch 3, but two or more cord-like bodies 4 may be wound around one winch 3. In this way, stabilization of the pressing state of the turning device body 2 against the wall surface 10 can be achieved, and the wall surface 10 can be more reliably cut by the cutting mechanism portion 2.

  Further, in the above example, the wall distance sensor 5, the outer periphery distance sensor 6, and the dust suction device 7 are provided in the turning device main body 2, but at least at least the wall distance sensor 5, the outer periphery distance sensor 6, and the dust suction device 7 It does not have to be either. Also in this case, the whole of the wall surface 10 in the cutting target range 11 can be automatically cut, and the burden of work when cutting the wall surface 10 can be reduced.

  Further, in the above example, the bending device 1 cuts the wall surface 10 of the elevator shaft 80, but the device is not limited to the wall surface 10 of the elevator shaft 80, and a device for bending a wall surface of a normal building You may make it cut by 1.
