[0002] As we all know, in coal mining, there are often inclined tunnels with slopes at the construction site. Inclined tunnels refer to inclined tunnels that do not go directly to the ground and are short in length. There must be walking aids for pedestrians, ventilation, and material transportation in the inclined tunnels. In addition, coal chutes and connecting tunnels are sometimes inclined tunnels with a large slope and a vertical depth of more than 50m and fewer people, and they must be equipped with mechanical personnel transportation devices.

[0003] The existing published patent number is: CN211521423U, which discloses a supporting wheel assembly for a pedestrian walker in a coal mine inclined shaft, including a vertical pole, a horizontal pole is arranged at the top of the vertical pole, a base is arranged at the bottom of the vertical pole, an upper wire-bearing wheel is arranged on one side of the vertical pole, a lower wire-bearing wheel is arranged below the upper wire-bearing wheel on one side of the vertical pole, an external threaded connecting rod is arranged at one end of the upper wire-bearing wheel, an internal threaded tube is arranged at one end of the external threaded connecting rod, a screw is arranged at the connection between the external threaded connecting rod and the internal threaded tube, a slider is arranged at one end of the internal threaded tube, an outer baffle is arranged on the outer side of the slider close to the upper wire-bearing wheel, and a slide groove is arranged on the inner side of the outer baffle. The supporting wheel assembly for a pedestrian walker in a coal mine inclined shaft described in the utility model is convenient for disassembly and installation of the wire-bearing wheel, and convenient for adjusting the upper and lower positions of the wire-bearing wheel at any time, so that the height of the wire rope can be freely adjusted.

[0004] Although the above scheme is convenient for disassembly and installation of the wire wheel, and is convenient for adjusting the upper and lower positions of the wire wheel at any time, so that the height of the wire rope can be freely adjusted, when the device is used to install the wire wheel, although it has the effect of replacing the wire wheel, it uses traditional screws to fix and install it during replacement, which reduces the installation efficiency and increases the installation time, making it very inconvenient to replace the wire wheel. Utility Model Content

[0005] The utility model aims to solve the problem that the installation efficiency is reduced by using traditional screws for fixing and then installing.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a support wheel assembly for a pedestrian walker in a coal mine inclined shaft, comprising: an outer frame, threaded rods are movably embedded on the upper and lower sides of the outer frame, the opposite ends of the two threaded rods are rotatably connected to hollow blocks through bearings, and sliding grooves are provided on both sides of the inner wall of the opposite side of the outer frame.

[0007] The technical effect of adopting the above further scheme is: rotating the threaded rod allows the hollow block to slide on its outer surface under the limit of the two slide grooves, and the sliding of the hollow block 104 can drive the wire wheel 113 to move, so that the height of the wire rope wrapped around the surface of the wire wheel 113 can be adjusted at will.

[0008] As a preferred embodiment, the two hollow blocks are slidably connected inside the two sliding grooves, and circular grooves are provided inside the two hollow blocks.

[0009] The technical effect of adopting the above further solution is that after the chuck penetrates the outer surfaces of the two semicircular blocks, it is embedded in the inner part of the circular groove.

[0010] As a preferred embodiment, the outer surfaces of the two hollow blocks are fixedly connected with square plates, and the outer surfaces at the centers of the two square plates are provided with circular holes.

[0011] The technical effect of adopting the above further solution is: the chuck is aligned with the circular hole, and the chuck contacts the outer surfaces of the two semicircular blocks.

[0012] As a preferred embodiment, a plurality of transverse grooves are formed on the outer surfaces of the two square plates, the interiors of the plurality of transverse grooves are slidably connected to limit L rods, and the outer surfaces of the plurality of limit L rods are fixedly connected to semicircular blocks.

[0013] The technical effect of adopting the above further solution is: when the chuck and the surface of the semicircular block are in contact with each other, the spring expands and contracts, and the limiting L rod slides to both sides inside the transverse groove.

[0014] As a preferred embodiment, the outer surfaces of the plurality of semicircular blocks are fixedly connected with pull bars, and the outer surfaces of the two square plates are provided with two long holes.

[0015] The technical effect of adopting the above-mentioned further scheme is: when it is necessary to remove the wire receiving wheel, move the pulling bar to both sides. At this time, the pulling bar moves inside the long hole, and the pulling bar drives the two semicircular blocks to move to both sides inside the horizontal groove. After the movement, the distance between the two semicircular blocks is greater than the diameter of the chuck. At this time, pull the chuck backwards and the wire receiving wheel is removed, which makes disassembly relatively simple.

[0016] As a preferred embodiment, the plurality of pull bars are movably embedded in the plurality of long holes, and chucks are movably embedded in the two round holes.

[0017] The technical effect of adopting the above further scheme is: the chuck passes through the outer surfaces of the two semicircular blocks and is embedded in the inside of the circular groove. The two springs limit the semicircular blocks, and the semicircular blocks limit the chuck. At this time, the wire wheel is installed inside the limiting L rod, which is simple to install and convenient for installing the wire wheel.

[0018] As a preferred embodiment, the outer surfaces of the two chucks are fixedly connected to the wire-receiving wheels, the two chucks are movably embedded in the two circular grooves, the two chucks are slidably connected to the outer surfaces of multiple semicircular blocks, the two chucks are slidably connected to the outer surfaces of multiple semicircular blocks, and the outer surfaces of the multiple semicircular blocks are fixedly connected to springs.

[0019] The technical effect of adopting the above further scheme is: aligning the chuck with the circular hole, the chuck contacts the outer surfaces of the two semicircular blocks, and the outer surfaces of the semicircular blocks close to the outside are arc-shaped, so that the chuck can easily slide to the other side of the semicircular block, and the limiting L rod slides to both sides inside the horizontal groove.

[0020] Compared with the prior art, the advantages and positive effects of the utility model are:

[0021] 1. When the utility model is in use, the threaded rod is rotated to allow the hollow block to slide on its outer surface under the limit of the two slide grooves. The sliding of the hollow block can make the height of the steel wire rope driven on the surface of the wire wheel be adjusted at will. When the wire wheel needs to be disassembled, the pull bar is moved to both sides. At this time, the pull bar moves inside the long hole, and the pull bar drives the two semicircular blocks to move to both sides inside the horizontal groove. After the movement, the distance between the two semicircular blocks is greater than the diameter of the chuck. At this time, the chuck is pulled backwards, and the wire wheel is removed, and the disassembly is relatively simple.

When the utility model is in use, when it is necessary to install the wire receiving wheel, the chuck is aligned with the circular hole, the chuck contacts the outer surfaces of the two semicircular blocks, the outer surfaces of the semicircular blocks close to the outside are in the shape of an arc, so that the chuck can easily slide to the other side of the semicircular blocks, and the limiting L rod slides to both sides inside the transverse groove, and when the chuck passes through the outer surfaces of the two semicircular blocks and is embedded in the inside of the circular groove, the two springs limit the semicircular blocks, and the semicircular blocks limit the chuck, and at this time the wire receiving wheel is installed inside the limiting L rod, which is simple to install and convenient for installing the wire receiving wheel.

[0028] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0030] See also Figure 1-4 The utility model provides a supporting wheel assembly for a pedestrian walker in a coal mine inclined shaft, comprising: an outer frame 101, threaded rods 102 are movably embedded on both upper and lower sides of the outer frame 101, and the opposite ends of the two threaded rods 102 are rotatably connected with hollow blocks 104 through bearings, and sliding grooves 103 are opened on both sides of the inner wall of the opposite side of the outer frame 101. The rotating threaded rod 102 allows the hollow block 104 to slide on its outer surface under the limit of the two sliding grooves 103. The sliding of the hollow block 104 can drive the wire wheel 113 to move, so that the height of the wire rope wrapped around the surface of the wire wheel 113 can be adjusted at will.

[0031] like Figure 1-4 As shown, the two hollow blocks 104 are slidably connected inside the two slide grooves 103 , and circular grooves 105 are opened inside the two hollow blocks 104 . After the chuck 115 passes through the outer surfaces of the two semicircular blocks 108 , it is embedded in the circular groove 105 .

[0032] like Figure 1-4 As shown, the outer surfaces of the two hollow blocks 104 are fixedly connected with square plates 106 , and the outer surfaces of the two square plates 106 at the center are provided with circular holes 107 . The chuck 115 is aligned with the circular holes 107 , and the chuck 115 contacts the outer surfaces of the two semicircular blocks 108 .

[0033] like Figure 1-4As shown, the outer surfaces of the two square plates 106 are provided with a plurality of transverse grooves 109, and the interiors of the plurality of transverse grooves 109 are all slidably connected with limit L rods 114, and the outer surfaces of the plurality of limit L rods 114 are all fixedly connected with semicircular blocks 108. When the chuck 115 contacts the surface of the semicircular block 108, the spring 110 expands and contracts, and the limit L rod 114 slides to both sides inside the transverse groove 109.

[0034] like Figure 1-4 As shown, the outer surfaces of the multiple semicircular blocks 108 are fixedly connected with the pulling bars 112, and the outer surfaces of the two square plates 106 are provided with two long holes 111. When it is necessary to remove the wire wheel 113, the pulling bars 112 are moved to both sides. At this time, the pulling bars 112 move inside the long holes 111, and the pulling bars 112 drive the two semicircular blocks 108 to move to both sides inside the transverse groove 109. After the movement, the distance between the two semicircular blocks 108 is greater than the diameter of the chuck 115. At this time, the chuck 115 is pulled backwards, and the wire wheel 113 is removed, and the disassembly is relatively simple.

[0035] like Figure 1-4 As shown, multiple pull bars 112 are movably embedded in multiple long holes 111, and chucks 115 are movably embedded in the two circular holes 107. The chuck 115 penetrates the outer surfaces of the two semicircular blocks 108 and is embedded in the circular groove 105. The two springs 110 limit the semicircular blocks 108, and the semicircular blocks 108 limit the chuck 115. At this time, the wire wheel 113 is installed in the limiting L rod 114. The installation is simple and convenient for installing the wire wheel 113.

[0036] like Figure 1-4 As shown, the outer surfaces of the two chucks 115 are fixedly connected with the wire-bearing wheels 113, the two chucks 115 are movably embedded in the two circular grooves 105, the two chucks 115 are slidably connected to the outer surfaces of multiple semicircular blocks 108, the outer surfaces of the multiple semicircular blocks 108 are fixedly connected with springs 110, the chucks 115 are aligned with the circular holes 107, the chucks 115 and the outer surfaces of the two semicircular blocks 108 are in contact with each other, so that the chucks 115 can easily slide to the other side of the semicircular blocks 108, and the limiting L rod 114 slides to both sides inside the transverse groove 109.

[0037] Working principle: When in use, the threaded rod 102 is rotated to allow the hollow block 104 to slide on its outer surface under the limit of the two slide grooves 103. The sliding of the hollow block 104 can drive the wire wheel 113 to move, so that the height of the wire rope wrapped on the surface of the wire wheel 113 can be adjusted at will. When the wire wheel 113 needs to be removed, the pull bar 112 is moved to both sides. At this time, the pull bar 112 moves inside the long hole 111, and the pull bar 112 drives the two semicircular blocks 108 to move to both sides inside the transverse groove 109. After the movement, the distance between the two semicircular blocks 108 is greater than the diameter of the chuck 115. At this time, the chuck 115 is pulled backwards and the wire wheel 113 is removed. Next, disassembly is relatively simple. When the wire wheel 113 needs to be installed, align the chuck 115 with the circular hole 107. The chuck 115 contacts the outer surfaces of the two semicircular blocks 108, so that the chuck 115 can easily slide to the other side of the semicircular block 108, and the limiting L rod 114 slides to both sides inside the transverse groove 109. When the chuck 115 passes through the outer surfaces of the two semicircular blocks 108 and is embedded in the circular groove 105, the two springs 110 limit the semicircular blocks 108, and the semicircular blocks 108 limit the chuck 115. At this time, the wire wheel 113 is installed inside the limiting L rod 114. The installation is simple and convenient for installing the wire wheel 113.
