Description

Technical Field

[0001] This utility model relates to the field of vehicle stopper technology, specifically to a linkage safety vehicle stopper for preventing runaway vehicles from cages. Background Technology

[0002] In the vertical shaft hoisting system of a mine, the cage, as a key transportation device, undertakes the important task of hoisting mine cars and transporting personnel and materials. The car stopper inside the cage is one of the core components that ensures the safety of cage transportation. Its main function is to prevent the mine cars from moving longitudinally during the hoisting and lowering of the cage, avoiding safety accidents such as collisions and derailments caused by the movement of the mine cars, and ensuring the smoothness and safety of the entire hoisting operation.

[0003] Currently, there is a wide variety of types of car stoppers in domestic mine cages, including manual and electric ones. The structure of current cage car stoppers is generally similar to that described in patent application CN201120200971.2, which discloses a cage with a car stop device. This includes a cage and a track fixed to the bottom of the cage. The key feature is the car stop device inside the cage, comprising a stopper and a drive mechanism. The stopper is a block, movably connected in the middle to a support on one side of the track. The drive mechanism is movably connected to the lower part of the stopper, pushing it to rotate around the support to stop and release the car. However, in practical use, this invention requires the car pusher to frequently enter the cage for operation, which is not only inefficient but also poses significant safety risks. Furthermore, manual operation can easily lead to delays or asynchrony in the action of the stoppers on both sides, potentially causing the mine car to shift during lifting.

[0004] The electric tank's internal vehicle stop device has a relatively complex structure, requires frequent battery replacement, which increases maintenance costs and workload. In addition, it has many potential failure points and poor explosion-proof performance, posing certain safety hazards in some mining environments with strict explosion-proof requirements.

[0005] In summary, existing cage arresters have significant safety risks and numerous potential points of failure.

[0006] Therefore, this utility model proposes a linkage safety brake for preventing runaway vehicles in cages, in order to solve the above-mentioned problems. Utility Model Content

[0007] The purpose of this utility model is to provide a linkage safety stopper for preventing runaway vehicles in cages, which solves the problems of high safety risks and numerous failure points in the existing technology.

[0008] The technical solution adopted by this utility model to solve its technical problem is:

[0009] A linkage safety vehicle stopper for preventing runaway vehicles from cages includes a cage bottom plate. The vehicle stopper is connected to the cage bottom plate and comprises a housing, a transmission turntable, and a rotating shaft. The transmission turntable is rotatably connected to the housing via the rotating shaft. The bottom of the rotating shaft is rotatably connected to the cage bottom plate, and a pull rod is connected to the top of the rotating shaft. The pull rod is perpendicular to the rotating shaft, and a foot pedal is connected to the end of the pull rod. The foot pedal surface is provided with a rubber anti-slip pad. Diagonal connecting rods are hinged at opposite corners of the transmission turntable. A vehicle-stopping claw is hinged to the end of each diagonal connecting rod away from the transmission turntable and is rotatably connected to the cage bottom plate. Anti-slip teeth are provided on the inner side of the vehicle-stopping claw. A strong magnetic assembly is provided between the bottom of the transmission turntable and the housing. The strong magnetic assembly includes a first magnetic block fixed to the bottom of the transmission turntable and a second magnetic block fixed to the housing.

[0010] Furthermore, the vehicle-stopping claw is rotatably connected to the bottom plate of the cage via a rotating shaft, the rotating shaft is rotatably connected to a connecting frame, and the connecting frame is detachably connected to the bottom plate of the cage.

[0011] Furthermore, a guide groove is provided on the rotating shaft, and a corresponding slider is provided on the anti-vehicle claw. The slider is slidably connected in the guide groove, and a clamping bolt is threadedly connected to the anti-vehicle claw.

[0012] Furthermore, the diagonal link includes a first link and a second link. One end of the first link is hinged to the transmission turntable, and the other end of the first link is hinged to the second link. The end of the second link away from the first link is hinged to the anti-vehicle claw. A T-shaped block is connected to the bottom of the second link. A limiting rail is connected to the housing corresponding to the T-shaped block. The limiting rail is detachably connected to the housing.

[0013] Furthermore, a limiting flange is provided at the edge of the transmission turntable, and a limiting block is provided at the bottom of the housing corresponding to the limiting flange.

[0014] Furthermore, the shell is detachably connected to the bottom plate of the cage via connecting lugs.

[0015] Furthermore, a coil spring is connected between the upper end of the rotating shaft and the housing; a bearing is connected between the lower end of the rotating shaft and the housing.

[0016] In summary, compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model uses a diagonal connecting rod to drive the two sides of the car-stopping claws to move synchronously, avoiding the problem of delayed or asynchronous movement on both sides of the manual car stopper, ensuring the consistency of the opening and closing of the car-stopping claws and improving the reliability of car stopping; at the same time, it adopts a foot-kick triggering method, which allows the operator to complete the operation without entering the cage, reducing safety risks, and can quickly realize the opening and closing of the car stopper, which is not affected by external factors such as power grid voltage, hydraulic pressure, and air pressure, and has high reliability.

[0018] 2. The transmission turntable and the rotating shaft of this utility model are connected by bearings, which reduces rotational friction and ensures smooth transmission; the limiting flange and the limiting stop cooperate to prevent the transmission turntable from rotating excessively.

[0019] 3. The car-stopping claw of this utility model is connected to the connecting frame via a rotating shaft. Both the connecting frame and the housing are detachable from the bottom plate of the cage, facilitating installation and adjustment. It is compatible with traditional mining systems, reducing upgrade costs for old cages. The guide groove on the rotating shaft cooperates with the slider of the car-stopping claw and is fixed with abutment bolts. The position of the car-stopping claw can be flexibly adjusted according to the size of the mine car, further enhancing its adaptability.

[0020] 4. The T-shaped block of this utility model cooperates with the limiting track to restrict the movement trajectory of the second link, ensure the stability of the transmission of the second link, avoid the wobbling of the blocking claw, and improve the stability of the blocking process.

[0031] like Figure 1-7 As shown, a linkage safety brake for preventing runaway trains in a cage includes a cage bottom plate 1. The brake is characterized by being connected to the cage bottom plate 1. The brake includes a housing 2, a transmission turntable 3, and a rotating shaft 4. The housing 2 is detachably connected to the cage bottom plate 1 via connecting lugs 5. The transmission turntable 3 is rotatably connected to the housing 2 via the rotating shaft 4, and the bottom of the rotating shaft 4 is rotatably connected to the cage bottom plate 1. A coil spring 6 is connected between the upper end of the rotating shaft 4 and the housing 2. A bearing 7 is connected between the lower end of the rotating shaft 4 and the housing 2. A pull rod 8 is connected to the top of the rotating shaft 4, and the pull rod 8 is perpendicular to the rotating shaft 4. A foot pedal 9 is connected to the end of the pull rod 8, and a rubber anti-slip pad 10 is provided on the surface of the foot pedal 9.

[0032] like Figure 4-6As shown, diagonal connecting rods are hinged at opposite corners of the transmission turntable 3. A car-stopping claw 12 is hinged to the end of the diagonal connecting rod away from the transmission turntable 3. The car-stopping claw 12 is rotatably connected to the bottom plate 1 of the cage. Anti-slip teeth 13 are provided on the inner side of the car-stopping claw 12. The diagonal connecting rod includes a first connecting rod 14 and a second connecting rod 15. One end of the first connecting rod 14 is hinged to the transmission turntable 3, and the other end of the first connecting rod 14 is hinged to the second connecting rod 15. The car-stopping claw 12 is hinged to the end of the second connecting rod 15 away from the first connecting rod 14. A T-shaped block 16 is connected to the bottom of the second connecting rod 15. A limiting rail 17 is connected to the housing 2 corresponding to the T-shaped block 16. The limiting rail 17 is detachably connected to the housing 2.

[0033] like Figure 4 As shown, the car-stopping claw 12 is rotatably connected to the cage bottom plate 1 via a rotating shaft 26. The rotating shaft 26 is rotatably connected to a connecting frame 18, and the connecting frame 18 is detachably connected to the cage bottom plate 1. A guide groove 19 is provided on the rotating shaft 26, and a corresponding slider 20 is provided on the car-stopping claw 12. The slider 20 is slidably connected in the guide groove 19, and a tightening bolt 21 is threadedly connected to the car-stopping claw 12.

[0034] like Figure 5 As shown, a strong magnetic assembly is provided between the bottom of the transmission turntable 3 and the housing 2. The strong magnetic assembly includes a first magnetic block 22 fixed to the bottom of the transmission turntable 3 and a second magnetic block 23 fixed to the housing 2. A limiting flange 24 is provided at the edge of the transmission turntable 3, and a limiting stop 25 is provided at the bottom of the housing 2 corresponding to the limiting flange 24.

[0035] The working process of this utility model is as follows:

[0036] In the initial state, the first magnetic block 22 at the bottom of the transmission turntable 3 and the second magnetic block 23 on the housing 2 attract each other, so that the transmission turntable 3 is in the initial angle and achieves self-locking. At this time, the coil spring 6 is in the natural state, and the two diagonal connecting rods drive the car blocking claw 12 to extend inward. The anti-slip teeth 13 on the inner side of the car blocking claw 12 lock the slide rail of the mine car wheel / axle / cage bottom plate 1, preventing the mine car from moving.

[0037] When the mine car needs to enter or exit the cage, the operator uses their foot to activate the foot pedal 9. The rubber anti-slip pad 10 on the surface of the foot pedal 9 increases friction, preventing slippage and improving operational safety. The foot pedal 9 then drives the rotating shaft 4 to rotate via the pull rod 8. The rotating shaft 4 drives the transmission turntable 3 to rotate around the bearing 7. As the transmission turntable 3 rotates, the first magnetic block 22 separates from the second magnetic block 23, the coil spring 6 is twisted and stores energy, and simultaneously the limiting flange 24 contacts the limiting stop 25, restricting excessive rotation of the transmission turntable 3.

[0038] When the transmission turntable 3 rotates, the first connecting rod 14 moves accordingly, which in turn drives the second connecting rod 15 to move. The T-shaped block 16 at the bottom of the second connecting rod 15 slides in the limiting track 17 of the housing 2, ensuring that the second connecting rod 15 moves in a fixed direction. Then, the second connecting rod 15 drives the car blocking claw 12 to rotate around the rotating shaft 26. At this time, the car blocking claw 12 opens, and the mine car can freely enter and exit the cage.

[0039] After the mine car has finished moving in and out, the operator releases the foot pedal 9, the coil spring 6 releases its stored force, and drives the rotating shaft 4 and the transmission turntable 3 to rotate in the opposite direction. The transmission turntable 3 drives the car-stopping claw 12 to rotate in the opposite direction through the diagonal connecting rod, causing the car-stopping claw 12 to gradually close. When the transmission turntable 3 returns to its initial position, the first magnetic block 22 and the second magnetic block 23 attract each other again to achieve self-locking, and the anti-slip teeth 13 on the inner side of the car-stopping claw 12 lock the mine car again, and the car stopper returns to its initial car-stopping state.

[0040] When it is necessary to stop mine cars of different sizes, the stopping claw 12 slides within the guide groove 19 of the rotating shaft 26 via the slider 20. After the stopping claw 12 rotates to the appropriate position, the position of the stopping claw 12 is fixed by tightening the clamping bolt 21. The housing 2 and the connecting frame 18 are both detachably connected to the cage bottom plate 1, thus enabling adaptation to traditional mining systems, modification of old cages, and reduction of upgrade costs.
