[0002] Transportation accidents are one of the main disasters in coal mines. They are caused by the mechanical parts of electromechanical equipment or other factors, which have a certain impact on production safety and the safety of workers' lives. At present, underground transportation personnel are mostly transported by overhead passenger devices. The inclined tunnels of some coal mines with overhead passenger devices are more than a kilometer long, and the maximum slope of the inclined tunnel is 10°~20°. The overhead passenger devices are usually fixed with ropes in a detachable and hanging manner.

[0003] The existing mining overhead passenger device is prone to being scratched or loosened during operation, causing the rope to fall off, thereby causing accidents. There are certain safety hazards and it is inconvenient to use. Therefore, we propose a mining overhead passenger anti-rope-off device to solve the above-mentioned problems. Utility Model Content

[0026] Example

[0027] Reference Figure 1-Figure 4 , a mine-used overhead passenger anti-rope device, comprising

[0028] Mounting plate 1;

[0029] Support wheel 2, lifting plate 3, fixed wheel 4, unlocking lever 5 and card block 12, support wheel 2 is fixedly connected to the left side of mounting plate 1, lifting plate 3 is slidably connected to the left side of mounting plate 1, fixed wheel 4 is fixedly connected to the bottom of lifting plate 3, unlocking lever 5 is rotatably connected to the top of lifting plate 3, card block 12 is slidably connected to the top of lifting plate 3, a card slot is opened on the left side of mounting plate 1, and card block 12 is engaged with the card slot;

[0030] The fixing mechanism is connected to the unlocking rod 5 and is used to drive the clamping block 12 to move and fix the lifting plate 3 and the fixing wheel 4.

[0031] By means of the above mechanism: the supporting wheel 2 and the fixed wheel 4 can be conveniently restricted through the mounting plate 1, and the rope can be conveniently fixed through the cooperation between the fixed wheel 4 and the supporting wheel 2 to prevent the rope from falling off, and the fixing mechanism can be conveniently driven by the unlocking rod 5 to move the card block 12, and the lifting plate 3 and the fixed wheel 4 can be conveniently fixed through the cooperation between the card block 12 and the card slot.

[0032] As an optimal solution of the present invention, the fixing mechanism includes: a connecting rod 6, a slide 7, a cross plate 8 and a reset plate 9; the connecting rod 6 is rotatably connected to the top of the unlocking rod 5, the slide 7 is slidably connected to the top of the lifting plate 3, and the right side of the slide 7 is rotatably connected to the left side of the connecting rod 6, the cross plate 8 is fixedly connected to the right side of the slide 7, the reset plate 9 is slidably connected to the top of the lifting plate 3, and the left side of the reset plate 9 is fixedly connected to the right side of the cross plate 8, and the right side of the reset plate 9 is fixedly connected to the left side of the card block 12. When the unlocking rod 5 is rotated, the connecting rod 6 is pushed. At this time, the movement of the connecting rod 6 will push the slide 7 to move left, and the left movement of the slide 7 will drive the cross plate 8 to move left. When the cross plate 8 moves, it will drive the reset plate 9 to move horizontally. At this time, the movement of the reset plate 9 will drive the card block 12 to move horizontally. At this time, the card block 12 moves out of contact with the card slot to unlock the lifting plate 3.

[0033] As a preferred solution of the present invention, a slide groove is symmetrically opened on the left side of the mounting plate 1, and there are two slide grooves. A slider 13 is symmetrically fixedly connected to the right side of the lifting plate 3, and there are two sliders 13. The outer walls of the two sliders 13 are slidably connected to the inner walls of the corresponding slide grooves. Through the cooperation of the slide groove and the slider 13, the lifting plate 3 is conveniently limited, so that the lifting plate 3 and the fixed wheel 4 can move vertically stably.

[0034] As a preferred solution of the present invention, the top of the lifting plate 3 is fixedly connected to a limiting plate 11, and the limiting plate 11 is a hollow structure. The inner wall of the limiting plate 11 is slidably connected to the outer wall of the horizontal plate 8. The limiting plate 11 is used to facilitate the limiting of the horizontal plate 8, so that the horizontal plate 8 can move stably laterally.

[0035] As a preferred solution of the present invention, a reset spring 10 is fixedly connected to the right side of the limit plate 11, and the right side of the reset spring 10 is fixedly connected to the left side of the reset plate 9. The elastic force of the reset spring 10 facilitates the horizontal movement and reset of the reset plate 9.

The rotating shaft facilitates the unlocking rod 5 to rotate around the rotating shaft as the center, thereby driving the connecting rod 6 to move.

[0037] The working principle of the present utility model is as follows: in actual use, when the anti-rope-stripping device needs to be used, the mounting plate 1 is first fixed in a suitable position by means of bolts or welding. When in use, the unlocking lever 5 is first pushed to rotate. When the unlocking lever 5 rotates, the connecting rod 6 is pushed. At this time, the movement of the connecting rod 6 will push the slide plate 7 to move left, and the left movement of the slide plate 7 will drive the cross plate 8 to move left. The cross plate 8 is limited by the limiting plate 11, so that the cross plate 8 can move laterally stably. When the cross plate 8 moves, it will drive the reset plate 9 to move laterally. At this time, the movement of the reset plate 9 will compress the reset spring 10. At the same time, the movement of the reset plate 9 will drive the card block 12 to move laterally. At this time, the card block 12 moves out of contact with the card slot, so that the lifting plate 3 is unlocked. At this time, the lifting plate 3 can be pushed When the lifting plate 3 is lifted up, it drives the fixed wheel 4 to move. The cooperation of the slider 13 and the slide groove makes the lifting plate 3 and the fixed wheel 4 move stably vertically. At this time, the supporting wheel 2 is placed in a suitable position so that the top of the supporting wheel 2 contacts the bottom of the rope. At this time, the lifting plate 3 is pushed down so that the bottom of the fixed wheel 4 contacts the top of the rope. At this time, the unlocking lever 5 is pushed to rotate and reset. The unlocking lever 5 rotates and drives the connecting rod 6 to reset. At the same time, the reset spring 10 pushes the reset plate 9 to move right. When the reset plate 9 moves, it drives the slide plate 7 to reset and drives the card block 12 to move horizontally and engage with the card slot to fix the lifting plate 3, thereby fixing the fixed wheel 4. Through the cooperation of the fixed wheel 4 and the supporting wheel 2, the rope is restricted to prevent it from detaching from the rope.

[0038] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
