Technical Field

[0001] This utility model relates to the field of mine safety equipment technology, specifically a stall protection device for trackless rubber-tired vehicles in mines. Background Technology

[0002] In recent years, rubber-tired vehicles have become an important auxiliary transportation method in modern mines, especially in underground coal mine transportation, where they offer advantages such as high efficiency, flexibility, and safety. However, during transportation in inclined or steep roadways, speed loss due to brake failure, gear shifting failure, or other mechanical malfunctions frequently occurs, leading to safety accidents, serious property damage, and casualties. Therefore, it is necessary to develop stall prevention devices for mining vehicles (rubber-tired vehicles, mine cars) to provide strong support for safe production in mines. Summary of the Invention

[0003] This utility model provides a stall protection device for trackless rubber-tired vehicles in mining, which addresses the problem of needing to intercept trackless rubber-tired vehicles after they stall.

[0004] This utility model is achieved using the following technical solution: a stall protection device for trackless rubber-tired vehicles in mines, comprising a left column and a right column. A left mounting plate is fixed to the top and bottom of the left column, and a bearing is fixed to the end of the left mounting plate. A guardrail is installed in the bearing within the left mounting plate at the top and bottom of the left column. A left guardrail is connected to the guardrail, and an intercepting net is inserted inside the left guardrail. A steel wire rope is connected to the portion of the intercepting net inserted inside the left guardrail. The steel wire rope passes through the left guardrail and its end is connected to a damper on the roadway floor. The intercepting net on the left guardrail is fixedly connected to the end of a locking hook. A cylinder clamp is fixed to the middle of the left column, and a rotating pin is provided at the end of the cylinder clamp. A left cylinder is connected to the rotating pin, and the piston rod of the left cylinder is hinged to one end of the guardrail clamp. The other end of the guardrail clamp is connected to the left side guardrail. The top of the right column... A pair of clamps are provided at the top and bottom of the column. Between the two clamps is a right mounting plate that fits onto the right column. A bearing is fixed at the end of the right mounting plate. A waist hole is also provided in the middle of the right mounting plate. A pin is connected between the two clamps and passes through the waist hole on the right mounting plate. A spring is connected between one of the clamps and the right mounting plate. A fence rod is installed in the bearing in the right mounting plate at the top and bottom of the right column. The fence rod is connected to the right fence. An interception net is inserted inside the right fence. The part of the interception net inserted inside the right fence is connected to a steel wire rope. The end of the steel wire rope after passing through the right fence is connected to a damper on the roadway floor. A cylinder clamp is fixed in the middle of the right column. A rotating pin is provided at the end of the cylinder clamp. The right cylinder is connected to the rotating pin. The piston rod of the right cylinder is hinged to one end of the fence rod clamp. The fence rod clamp is connected to the fence rod on the right side.

[0005] This utility model's stall protection device is installed and fixed inside the roadway. The left and right railings are normally closed, and the hook end can hook the end of the interception net on the right railing located outside the right railing. When the trackless rubber-tired vehicle stalls, it crashes into the interception net on the left and right railings. Upon impact, the interception net detaches from the left and right railings and, under the action of the damper, stops the stalled trackless rubber-tired vehicle.

[0006] The aforementioned stall protection device for trackless rubber-tired vehicles in mines comprises a left fence consisting of an even number of steel pipes arranged vertically from top to bottom, which are connected by vertical pipes to form the left fence; and a right fence consisting of an even number of steel pipes arranged vertically from top to bottom, which are connected by vertical pipes to form the right fence.

[0007] The aforementioned stall protection device for trackless rubber-tired vehicles in mines uses a U-shaped steel pipe as its interception net. A U-shaped steel pipe is inserted into every two steel pipes of the left fence, with the U-shaped end of the U-shaped steel pipe outside the left fence. The two ends of the U-shaped steel pipe are inside and fixed within the steel pipes of the left fence, and the two ends of the U-shaped steel pipe are connected to steel wire ropes. Similarly, a U-shaped steel pipe is inserted into every two steel pipes of the right fence, with the U-shaped end of the U-shaped steel pipe outside the right fence. The two ends of the U-shaped steel pipe are inside and fixed within the steel pipes of the right fence, and the two ends of the U-shaped steel pipe are connected to steel wire ropes.

[0008] This utility model has the following advantages: 1) The wire rope is neatly arranged inside the steel pipe of the fence, the wire rope is not easy to wear, and the wire rope forms a ring through the steel pipe, and then forms a large closed-loop vehicle barrier through the locking hook. 2) After the left and right fences are closed, the right cylinder has a tightening action to prevent the locking hook from disengaging. Therefore, the left and right fences can achieve self-locking and locking, and the rubber-wheeled vehicle can unlock and open the door by itself after stalling. 3) The device is not welded as a whole, and the door cabinet can be adjusted left, right and up and down to adapt to various alleys.

Detailed Implementation

[0020] The stall protection device for trackless rubber-tired vehicles in mines includes two columns, left and right, which are fixed to the roadway floor. A left mounting plate 3 is fixed to the top and bottom of the left column 1, and a bearing is fixed to the end of the left mounting plate 3. A guardrail 4 is installed in the bearing within the left mounting plate at the top and bottom of the left column. A left guardrail 5 is connected to the guardrail 4. The left guardrail 5 includes four steel pipes arranged vertically from top to bottom, connected by vertical pipes to form the left guardrail. A U-shaped steel pipe 17 is inserted into every two steel pipes of the left guardrail 5, with the U-shaped end of the U-shaped steel pipe 17 outside the left guardrail. The two ends of the U-shaped steel pipe 17 are fixed inside the steel pipe of the left fence 5. The two ends of the U-shaped steel pipe 17 are also connected to steel wire ropes 18. The ends of the steel wire ropes 18 are connected to dampers 19 on the roadway floor. A cylinder clamp 12 is fixed in the middle of the left column 1. A rotating pin 13 is provided at the end of the cylinder clamp 12. The left cylinder 14 is connected to the rotating pin 13. The piston rod of the left cylinder 14 is hinged to one end of the fence clamp 20. The other end of the fence clamp 20 is connected to the fence 4 on the left side. A pair of clamps 6 are provided at the top and bottom of the right column 2. A right mounting plate 7 is provided between the two clamps 6 and fitted on the column. A bearing is fixed to the end of the right mounting plate 7. A waist hole 8 is provided in the middle of the right mounting plate. A pin 9 is connected between the two clamps 6. The pin 9 passes through the waist hole 8 on the right mounting plate 7. A spring 10 is connected between one of the clamps 6 and the right mounting plate 7. A fence post 4 is installed in the bearings in the right mounting plate 7 at the top and bottom of the left column. The fence post 4 is connected to the right fence. The right fence 11 includes four steel pipes arranged vertically from top to bottom. The four steel pipes are connected by vertical pipes to form the right fence. A U-shaped steel pipe 17 is inserted into every two steel pipes of the right fence. The U-shaped end of the U-shaped steel pipe 17 is outside the right fence. The two ends of U-shaped steel pipe 17 are fixed inside the steel pipe of the right fence. The two ends of U-shaped steel pipe 17 are also connected to steel wire rope 18. The end of steel wire rope 18 is connected to damper 19 on the roadway floor. Cylinder clamp 12 is fixed in the middle of right column 2. Rotating pin 13 is provided at the end of cylinder clamp 12. Right cylinder 15 is connected to rotating pin 13. The piston rod of right cylinder 15 is hinged to one end of fence clamp 20. Fence clamp 20 is connected to fence 4 on the right side. The U-shaped end of U-shaped steel pipe 17 on left fence is fixedly connected to lock hook 16. The hook end of lock hook 16 can hook the U-shaped end of U-shaped steel pipe 17 on right fence.

[0021] This utility model stall protection device is installed and fixed in the roadway. The left fence 5 and right fence 11 are normally closed. The hook end of the locking hook 16 hooks the U-shaped end of the U-shaped steel pipe 17 on the right fence (the locking hook 16 is in the locked state). The right mounting plate 7 on the right column 2 is restricted to the first extreme position by the pin 9. The spring 10 is in the stretched state. When the speed of the trackless rubber-tired vehicle in the mine is normal, the left fence 5 and right fence 11 need to be opened to allow the trackless rubber-tired vehicle to pass normally. First, the piston rod of the right cylinder 15 extends. Under the action of the restoring force, the spring 10 drives the right mounting plate 7 to rotate. Due to the restriction of the pin, the right mounting plate 7 rotates to the second extreme position. At this time, the spring 10 is in the natural state. During the rotation of the right mounting plate 7, it drives the right fence 11 on the right mounting plate 7 to move to the left. After the right mounting plate 7 rotates to the second extreme position, the right fence 11 moves to the leftmost end. At this time, the U-shaped end of the U-shaped steel pipe 17 on the right fence... After the hook end of the locking hook 16 is disengaged (the locking hook 16 is in the loose state), the right mounting plate 7 reaches its limit position and cannot rotate. As the piston rod of the right cylinder 15 extends, it drives the fence rod 4 to rotate, and drives the right fence 11 to rotate. At the same time as the piston rod of the right cylinder 15 moves, the piston rod of the left cylinder 14 also extends, driving the left fence 5 to rotate through the fence rod 4. After both the left fence 5 and the right fence 11 rotate and open, the trackless rubber-tired vehicle in the mine can pass normally. After the trackless rubber-tired vehicle passes, the left fence 5 and the right fence 11 need to be closed again. The piston rods of the left cylinder 14 and the right cylinder 15 retract at the same time, and the left fence 5 and the right fence 11 rotate at the same time. After returning to the closed position, the piston rod of the right cylinder 15 continues to retract to tighten, pulling the right mounting plate 7 to rotate to the first limit position. The spring 10 is in the stretched state again, and the locking hook 16 locks the U-shaped steel pipe 17 on the left fence 5 and the right fence 11 (the locking hook 16 is in the locked state). If the trackless rubber-tired vehicle in the mine loses speed, and the left fence 5 and right fence 11 remain closed, the trackless rubber-tired vehicle will collide with the U-shaped steel pipe 17 on the left fence 5 and right fence 11. The U-shaped steel pipe 17 will detach from the left fence 5 and right fence 11 upon impact and, under the action of the damper 19, will stop the runaway trackless rubber-tired vehicle. Afterwards, the U-shaped steel pipe 17 can be reset to allow for the next interception operation.

[0022] The intrinsically safe radar speed sensor for mining applications can monitor the vehicle's operating speed in real time. If the speed exceeds the specified operating speed and remains in an overspeeding state for 3 seconds (the time is adjustable), the left fence 5 and right fence 11 will remain closed (the fences are normally closed). If the speed is normal, the left fence 5 and right fence 11 will be opened by using a cylinder as the power actuator.
