An emergency escape device for mine mule

Abstract

The application discloses a mine monkey car emergency danger avoiding device and belongs to the field of mine monkey cars. When a miner needs to avoid danger, the miner presses down an operating rod. The operating rod rotates downward around the operating rod rotating shaft and drives the inserting rod and the mounting block to move downward, so that the mounting block approaches the monkey car frame. At this time, the lower guide groove, the rotating rod and the upper guide groove rotate in the clockwise direction. This causes the sliding rod to move rightward. When the sliding rod moves rightward, the limiting hole moves rightward; when the limiting hole moves to the position of the limiting rod, the limiting rod falls into the limiting hole under the action of the tension spring, and then the sliding rod is locked. After locking, the guide ring and the arc-shaped clamp form an annular structure with a gap left at the upper portion. Under the guidance of the guide rail, the walking angle of the monkey car frame starts to deviate. At this time, the clamping block no longer clamps the cable, and the monkey car frame enters the buffer inclined shaft. The application provides a danger avoiding means for the miner when using the monkey car and can solve the safety accidents caused by the rapid falling of the monkey car to the shaft bottom.

Description

TECHNICAL FIELD

[0001] The present application relates to the field of mine monkey car, in particular to a mine monkey car emergency device. BACKGROUND

[0002] Monkey car is mainly used for underground mine auxiliary transport workers. The steel wire rope is installed on the driving wheel, the rope supporting wheel, the rope pressing wheel and the detour wheel, and is pulled tight by the tensioning device. The driving device outputs power to drive the driving wheel and the steel wire rope to run, realizing the transportation of miners. The purpose of transporting miners by monkey car is to shorten the time of miners going up and down the well and reduce the physical consumption of miners.

[0003] But the monkey car may slip down in the use process. This is because the monkey car traction head cannot hold the rope tightly, and the miners fall rapidly to the bottom of the well due to gravity, causing safety accidents. Therefore, a mine monkey car emergency device is needed to solve the above problems. SUMMARY

[0004] The present application provides a mine monkey car emergency device, which aims to solve the safety accidents induced by the rapid fall of the monkey car to the bottom of the well.

[0005] The application adopts the technical scheme and provides an emergency escape device for a mine monkey car, which comprises an inclined shaft, a cable, a buffer inclined lane, a guide rail, an upper protruding block, a mounting block, a plug rod, a monkey car frame, a clamping block, a sliding rod, a lower protruding block, an upper guide groove, a rotating rod, a lower guide groove, a guide ring, an arc-shaped clamp, a contact rod, an upper vertical plate, an operating rod, a sliding hole, a limiting rod, a tension spring, a limiting hole, a mounting frame, a guide rod, a damping plate, a rubber layer, a spring, a check plate, a torsion spring, a fixing frame, a rotating rod rotating shaft and an operating rod rotating shaft.

[0006] Further description of the above technical scheme is as follows: the damping buffer mechanism comprises a mounting frame, the mounting frame is installed below the top plate of the buffer inclined lane, a plurality of guide rods are inserted into the mounting frame, the bottom end of the guide rod is fixed with a damping plate, the bottom of the damping plate is installed with a rubber layer, the guide rod between the damping plate and the mounting frame is provided with a spring, the bottom of the outer end of the damping plate is installed with a rotatable check plate, the check plate is provided with a torsion spring, when the monkey car frame enters the buffer inclined lane, the monkey car frame gradually slows down due to the gradually increasing height of the guide rail, when the guide ring contacts the check plate, the guide ring opens the check plate and contacts the rubber layer, under the friction of the rubber layer, the monkey car frame continues to slow down, and the check plate limits the monkey car frame from being taken out of the buffer inclined lane.

[0007] Further description of the above technical scheme is as follows: the lower protruding block is welded on the outer surface of the monkey car frame, and the upper protruding block is welded on the outer surface of the sliding rod.

[0008] As a further description of the above technical solution: the outer end of the curved section of the guide rail is a tapered structure, facilitating butt joint with the guide ring.

[0009] As a further description of the above technical solution: the sliding hole is close to the rotating shaft of the operating rod, thereby providing a larger torque.

[0010] As a further description of the above technical solution: the distance from the rotating shaft of the rotating rod to the lower protruding block is greater than the distance from the rotating shaft of the rotating rod to the upper protruding block, thereby providing a larger torque.

[0011] As a further description of the above technical solution: the fixed frame is connected with the guide rail in a screwing manner.

[0012] As a further description of the above technical solution: in the danger-avoiding state, after the arc-shaped clamp is rotated in the counterclockwise direction and locked, the gap width between the upper end of the arc-shaped clamp and the upper end of the guide ring is greater than the width of the fixed frame.

[0013] As a further description of the above technical solution: the guide rail is a rigid rod.

[0014] The present application provides a mine monkey car emergency danger-avoiding device, which has the following beneficial effects:

[0015] (1) The present application sets clamping blocks and mounting blocks. When a miner sits on the monkey car frame, the clamping blocks and the mounting blocks will be tightly pressed against each other and form a clamping action on the cable under the weight of the miner, so as to play the function of normal walking of the monkey car frame along the cable;

[0016] (2) The present application sets a guide ring and an arc-shaped clamp. When danger needs to be avoided, the miner can press down the operating rod. Based on the connecting rod transmission, the arc-shaped clamp is rotated in the counterclockwise direction and clamps the guide rail together with the guide ring. At this time, the monkey car frame enters the buffer inclined roadway under the action of the guide rail and completes the danger avoidance;

[0017] (3) A limiting hole is arranged on the sliding rod. During the danger-avoiding process, after the miner presses down the operating rod, the limiting hole will walk to the right. When the limiting hole coincides with the position of the limiting rod, the limiting rod will enter the limiting hole and lock the sliding rod under the action of the tension spring. After the sliding rod is locked, the upper vertical plate will lock the state of the arc-shaped clamp, so that the arc-shaped clamp and the guide ring always maintain clamping on the guide rail. At this time, the miner does not need to continue to press down the operating rod, reducing the operation difficulty of the miner;

[0018] (4) There are not less than three buffer inclined roadways arranged from top to bottom along the extension direction of the inclined shaft. Therefore, the miner can press down the operating rod at different positions when using the monkey car and enter the buffer inclined roadway and complete the danger avoidance. Since the number of buffer inclined roadways is not less than three, when the monkey car reaches the bottom of the inclined shaft, the miner has at least three opportunities to enter the buffer inclined roadway and complete the danger avoidance, improving the possibility of successful danger avoidance;

[0019] (5) The height of the buffer inclined lane gradually inclines upward. Therefore, when the monkey car frame enters the buffer inclined lane, the monkey car frame will gradually slow down under the condition of gravity work. In addition, a damping buffer mechanism is arranged in the buffer inclined lane. When the monkey car frame walks in the buffer inclined lane, the rubber layer will be rubbed with the guide ring and the arc-shaped clamp, so as to make the monkey car frame continue to slow down; in the process of rubbing the rubber layer with the guide ring and the arc-shaped clamp, the spring above the damping plate will be repeatedly compressed upward and downward, so as to make the rubber layer below the damping plate repeatedly rub the guide ring and the arc-shaped clamp, and the deceleration effect on the monkey car frame is improved. After deceleration through the two ways, the monkey car frame can be quickly parked in the buffer inclined lane, so as to ensure the safety of the miners;

[0020] (6) The buffer inclined lane is provided with a check plate and a torsion spring. Under the joint action of the two, the monkey car frame can enter the buffer inclined lane from the inclined shaft, but cannot retreat from the buffer inclined lane to the inclined shaft. This avoids the possibility that the miners retreat from the buffer inclined lane to the inclined shaft again, and ensures the safety of the miners. BRIEF DESCRIPTION OF DRAWINGS

The rotating rod 13 is mounted on the mounting block 6 through the rotating rod pivot 32 at the middle upper part, and the lower guide groove 14 is formed in the lower part of the rotating rod 13. The lower guide groove 14 is slidably provided with the lower protruding block 11, and the lower protruding block 11 is fixedly connected with the monkey car frame 8. The sliding rod 10 is provided with the upper vertical plate 18 at the left end. The upper vertical plate 18 is provided with the operating rod 19 at the middle upper part. The operating rod 19 is rotatable. The insertion rod 7 is provided with the sliding hole 20 at the lower end. The operating rod 19 passes through the sliding hole 20. The mounting block 6 is slidably and insertingly provided with the limiting rod 21, and the limiting rod 21 is sleeved with the tension spring 22. The sliding rod 10 is provided with the limiting hole 23 at the left side. The buffer inclined lane 3 is provided with a damping buffer mechanism.

[0027] In a specific embodiment: the damping buffer mechanism comprises a mounting frame 24 installed below the top plate of the buffer inclined drift 3; the mounting frame 24 is inserted with a plurality of guide rods 25; the bottom end of the guide rod 25 is fixed with a damping plate 26, and the bottom of the damping plate 26 is installed with a rubber layer 27; the guide rod 25 between the damping plate 26 and the mounting frame 24 is provided with a spring 28; the bottom of the outer end of the damping plate 26 is installed with a rotatable check plate 29, and the check plate 29 is provided with a torsion spring 30; when the monkey car frame 8 enters the buffer inclined drift 3, the height of the guide rail 4 gradually rises, and the monkey car frame 8 gradually slows down; when the guide ring 15 contacts the check plate 29, the guide ring 15 pushes the check plate 29 open and contacts the rubber layer 27; under the friction of the rubber layer 27, the monkey car frame 8 continues to slow down; the check plate 29 limits the monkey car frame 8 from being pulled out of the buffer inclined drift 3.

[0028] In a specific embodiment: the lower protruding block 11 is welded on the outer surface of the monkey car frame 8; the upper protruding block 5 is welded on the outer surface of the sliding rod 10.

[0029] In a specific embodiment: the outer end of the curved section of the outer side of the guide rail 4 is a tapered structure, which facilitates the butt joint with the guide ring 15.

[0030] In a specific embodiment: the sliding hole 20 is close to the operating rod pivot 33, thereby providing a larger torque.

[0031] In a specific embodiment: the distance from the rotating rod pivot 32 to the lower protruding block 11 is greater than the distance from the rotating rod pivot 32 to the upper protruding block 5, thereby providing a larger torque.

[0032] In a specific embodiment: the fixed frame 31 is connected with the guide rail 4 in a screwing manner.

[0033] In a specific embodiment: in the risk avoidance state, after the arc-shaped clamp 16 is rotated in the counterclockwise direction and locked, the gap width between the upper end of the arc-shaped clamp 16 and the upper end of the guide ring 15 is greater than the width of the fixed frame 31.

[0034] In a specific embodiment: the guide rail 4 is a rigid rod member.

[0035] In specific use, the miner sits on the monkey car frame 8. Under the action of gravity, the lower protruding block 11 moves downward, driving the lower guide groove 14, the rotating rod 13, and the upper guide groove 12 to rotate counterclockwise as a whole. This causes the upper protruding block 5 to move leftward and press the clamping block 9 through the sliding rod 10. The upper part of the clamping block 9 is pushed leftward, causing the lower part of the clamping block 9 to rotate rightward and clamp the cable 2 together with the mounting block 6. At this time, the arc-shaped clamp 16 remains in an open state. When the monkey car frame 8 moves to the position of the curved section of the outer side of the guide rail 4, the guide ring 15 cannot catch the guide rail 4 because the arc-shaped clamp 16 remains in an open state. Therefore, in the normal working state, the monkey car frame 8 always walks in the inclined shaft 1.

[0036] When the miner needs to take refuge, the miner presses down the operating rod 19. Part of the weight of the miner is borne on the operating rod 19 and causes the operating rod 19 to rotate downward around the operating rod pivot 33. The downward rotating operating rod 19 drives the insertion rod 7 and the mounting block 6 to move downward, causing the mounting block 6 to approach the cage frame 8. At this time, the lower guide slot 14, the rotating rod 13, and the upper guide slot 12 rotate as a whole in the clockwise direction. This causes the sliding rod 10 to move to the right. This causes the upper vertical plate 18 to move to the right and drives the arc-shaped clamp 16 to rotate in the counterclockwise direction. When the sliding rod 10 moves to the right, the limiting hole 23 moves to the right; when the limiting hole 23 moves to the position of the limiting rod 21, the limiting rod 21 falls into the limiting hole 23 under the action of the tension spring 22, thereby locking the sliding rod 10. After locking, the guide ring 15 and the arc-shaped clamp 16 form a ring structure with a gap at the top. At the same time, the upper vertical plate 18 can lock the state of the arc-shaped clamp 16, ensuring that the guide ring 15 and the arc-shaped clamp 16 always clamp the guide rail 4. At this time, the miner does not need to continue to press down the operating rod, reducing the difficulty of the miner's operation.

[0037] Under the guidance of the guide rail 4, the walking angle of the cage frame 8 begins to deviate. When the deviation occurs, the cable 2 pushes the clamping block 9 away to the left. At this time, the clamping block 9 no longer clamps the cable 2, and the clamping block 9, the mounting block 6, and the cable 2 are separated, and the cage frame 8 enters the buffer inclined drift 3.

[0038] When the cage frame 8 enters the buffer inclined drift 3, the cage frame 8 gradually slows down due to the gradual upward inclination of the buffer inclined drift 3. At the same time, when the cage frame 8 enters the buffer inclined drift 3, the guide ring 15 and the arc-shaped clamp 16 rub against the rubber layer 27. Under the action of friction, the cage frame 8 will further slow down. In addition, the check plate 29 prevents the cage frame 8 from retreating back into the inclined shaft 1, protecting the safety of the miner.

[0039] The present application is not limited to the above best mode of implementation, and anyone can derive other various forms of products under the inspiration of the present application, but regardless of any changes in shape or structure, any technical solution with the same or similar to the present application falls within the scope of protection of the present application.
