[0002] Coal mine monorail car is a kind of transportation equipment specially designed for underground transportation in coal mines, mainly used for transporting coal, ore, materials and personnel. Monorail car has been widely used in underground transportation in coal mines due to its compact structure, easy operation and small space occupation. However, when the monorail car moves on the track, the various parts are only connected by connecting rods for rotation, and the connecting rods cannot keep the various parts of the monorail car centered. When the monorail car reaches the turning point of the track, some parts may tilt outward and cause derailment, which will affect the normal operation of the monorail car, which is inconvenient.

[0003] Therefore, a coal mine monorail crane track auxiliary centering and anti-derailing device has been developed that can center the monorail mine car to prevent the monorail mine car from derailing when turning on the track, thereby affecting the normal operation of the monorail mine car. Summary of the invention

DETAILED DESCRIPTION

[0033] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0034] A track auxiliary centering and anti-derailment device for a coal mine monorail crane, such as Figure 1 and Figure 2 As shown, it includes a connecting frame 1, a connecting rod 2, a first roller 3, a first sliding frame 4 and a fixing mechanism 5. The connecting frame 1 is connected to the connecting rod 2 on the left side, and eight first rollers 3 are rotatably connected to the lower part of the connecting frame 1. The upper left side of the connecting frame 1 is connected to two front and rear first sliding frames 4. Six balls are rotatably provided on the first sliding frames 4 to facilitate movement on the track. The connecting frame 1 is provided with a fixing mechanism 5.

[0035] like Figure 1 , Figure 3 and Figure 4 As shown, a fixing mechanism 5 is also included, and the fixing mechanism 5 includes a fixing plate 50, a rotating frame 51, a first torsion spring 52 and a clamping frame 53. The front and rear sides of the right part of the connecting frame 1 are connected to the fixing plates 50, and the rotating frames 51 are rotatably connected to the fixing plates 50. The rotating frames 51 are connected to the fixed plates 50 connected thereto with two upper and lower first torsion springs 52. The right side of the rotating frames 51 is connected to the clamping frames 53, and the clamping frames 53 are provided with anti-slip pads to enhance the clamping stability.

[0036] When using the present invention, first, according to the operation requirements of the monorail mine car, a corresponding number of connecting frames 1 are sequentially installed in the track, and two adjacent connecting frames 1 are spliced ​​by the connecting rod 2. When the monorail mine car moves in the track, the connecting frame 1 is driven to move, and the first roller 3 and the first sliding frame 4 move on the track. When the connecting frames 1 are sequentially installed in the track, the rotating frame 51 on the fixed plate 50 can be rotated outward, and the first torsion spring 52 is deformed. Then, the next connecting frame 1 is installed in the track, and then the rotating frame 51 is released, and the first torsion spring 52 is restored, so that the rotating frames 51 are close to each other, and the clamping frames 53 are driven to be close to each other, so that the clamping frames 53 clamp the next connecting frame 1. When the monorail mine car moves to the turning point of the track, the clamping frame 53 can be deformed within a certain range to limit the next connecting frame 1, so as to prevent the connecting frame 1 from tilting outward and causing derailment, thereby playing the role of being able to center the monorail mine car, and preventing the monorail mine car from derailing when turning at the track, which affects the normal operation of the monorail mine car.

[0037] like Figure 1 , Figure 5 and Figure 6 As shown, it also includes a guide mechanism 6, which includes a fixed bracket 60, a fixed bracket 61, a gear 62, a second torsion spring 63, a first connecting tooth plate 64, a moving roller 65, a second connecting tooth plate 66, a first spring 67, a guide moving bracket 68 and a rack 69. The upper side of the middle of the connecting frame 1 is connected to the front and rear fixed brackets 60, and the upper side of the fixed bracket 60 is connected to the fixed bracket 61. The upper and lower parts of the fixed bracket 61 are both rotatably connected to the gear 62. The second torsion spring 63 is connected between the gear 62 and the connected fixed bracket 61. The inner side of the gear 62 They are all connected with a first connecting tooth plate 64, and a moving roller 65 is rotatably connected to the middle of the fixed frame 61. The upper and lower sides of the moving roller 65 are slidably connected with a second connecting tooth plate 66. Six first springs 67 are connected between the second connecting tooth plates 66 and the connected moving rollers 65. The second connecting tooth plates 66 are meshed with adjacent first connecting tooth plates 64. A guide moving frame 68 is slidably connected on one side of the lower part of the fixed bracket 60 that is away from each other. The upper and lower parts of the guide moving frame 68 are connected with racks 69, and the racks 69 are meshed with adjacent gears 62.

[0038] The guide mechanism 6 of the present device can be used to guide the connecting frame 1. When the connecting frame 1 is installed in the track, the moving roller 65 contacts the track. When the connecting frame 1 moves, the moving roller 65 rotates, driving the second connecting tooth plate 66 to rotate. The second connecting tooth plate 66 is kept meshed with the first connecting tooth plate 64 through the force of the first spring 67, thereby driving the first connecting tooth plate 64 to rotate, so that the gear 62 rotates, and the second torsion spring 63 is deformed. While the gear 62 rotates, it meshes with the rack 69 to drive the guide moving frame 68 to move, so that the guide moving frame 68 moves rightward to the outside of the rotating frame 51, thereby limiting the rotating frame 51 and preventing the rotating frame 51 from rotating outward and separating from the connecting frame 1. After the guide moving frame 68 moves to the limit, the second connecting tooth plate 66 moves on the first connecting tooth plate 64 and no longer drives the first connecting tooth plate 64 to rotate. When the moving roller 65 stops moving, the second torsion spring 63 is restored, so that the gear 62 is reset, and then the guide moving frame 68 is reset.

[0039] like Figure 1 , Figure 7 , Figure 8 , Fig. 9 and Fig.11 As shown, it also includes a locking mechanism 7, which includes a connecting column 70, an inclined plate 71, a second sliding frame 72 and a connecting support plate 73. The left side of the lower part of the rotating frame 51 is connected to the connecting column 70, and the lower part of the connecting column 70 is connected to the inclined plate 71. The front and rear sides of the lower part of the connecting frame 1 are slidably connected to the second sliding frame 72, and the second sliding frame 72 is slidably matched with the adjacent inclined plate 71. The second sliding frame 72 is connected to the connecting support plate 73, and the upper part of the connecting support plate 73 is connected to the adjacent guide movable frame 68.

[0040] By using the locking mechanism 7 of the device, the rotating frame 51 can be locked, and while the guide movable frame 68 moves to the right, it drives the second sliding frame 72 to move to the right along the inclined plate 71, so that the second sliding frame 72 squeezes the connecting column 70 to move inward, and then squeezes the rotating frame 51 to move inward, thereby further locking the rotating frame 51 and enhancing the stability of the rotating frame 51.

[0041] like Figure 1 and Fig.10 As shown, it also includes a limiting mechanism 8, which includes a handle 80, a screw rod 81 and a moving block 82. The screw rod 81 is rotatably connected to the side of the left part of the rotating frame 51 that is away from each other, and the handle 80 is connected to the right side of the screw rod 81. The moving blocks 82 are threadedly connected to the screw rod 81. The moving blocks 82 are slidably connected to the adjacent rotating frame 51, and the moving blocks 82 are located on the inner side of the adjacent guide moving frame 68.

[0042] By using the limiting mechanism 8 of the device, the rotating frame 51 can be squeezed inward, and the handle 80 is turned to drive the screw rod 81 to rotate, so that the moving block 82 moves, and the moving block 82 is adjusted to a suitable position so that the moving block 82 is squeezed when the guide moving frame 68 moves to the right, thereby squeezing the rotating frame 51 inward and ensuring that the rotating frame 51 stably clamps the connecting frame 1.

[0043] like Figure 1 and Fig.12 As shown, an auxiliary mechanism 9 is also included, which includes a guide plate 90, a second roller 91 and a second spring 92. The right part of the connecting frame 1 is slidably connected to the front and rear guide plates 90, and the left and right parts of the guide plate 90 are both rotatably connected to the second roller 91. The guide plates 90 are connected to the connecting frame 1 with a second spring 92.

[0044] The auxiliary mechanism 9 of the device can assist the connection frame 1 in moving. The second roller 91 on the guide plate 90 is pressed against the track by the force of the second spring 92. When the connection frame 1 moves, the second roller 91 rotates, thereby enabling the connection frame 1 to move more smoothly on the track.

[0045] like Figure 1 and Fig.12 As shown, an extension mechanism 10 is also included, and the extension mechanism 10 includes a connecting plate 100, a clamping plate 101 and a third torsion spring 102. The right side of the clamping frame 53 is connected to the connecting plate 100, and the right side of the connecting plate 100 is rotatably connected to the clamping plate 101. The third torsion spring 102 is connected between the upper and lower parts of the clamping plate 101 and the connected connecting plate 100.

[0046] By using the extension mechanism 10 of the present device, the clamping stability of the rotating frame 51 on the connecting frame 1 can be enhanced. The clamping plate 101 on the rotating connecting plate 100 is deformed, and after the connecting frame 1 is installed, the clamping plate 101 is loosened and the third torsion spring 102 is restored, so that the clamping plates 101 are close to each other to clamp the connecting frame 1, thereby enhancing the clamping stability of the rotating frame 51 on the connecting frame 1 and preventing the connecting frame 1 from derailing.

When the clamping plate (101) on the connecting plate (100) is rotated, the third torsion spring (102) is deformed. After the connecting frame (1) is installed, the clamping plate (101) is loosened and the third torsion spring (102) is restored, so that the clamping plates (101) are close to each other to clamp the connecting frame (1).
