Description

Technical Field

[0001] This utility model belongs to the technical field of mining equipment, specifically relating to an adjustable wheelbase cage internal car stopper. Background Technology

[0002] The cage is the core personnel and material transport equipment in the mine vertical hoisting system. It resembles a closed or semi-closed metal frame, and the inside can be laid with guide rails that connect with the underground track. It is mainly used to safely and efficiently transport materials such as mine cars, coal, and equipment, as well as underground workers, from underground to the surface, or from the surface to a designated level underground. It is an indispensable key equipment for vertical transportation in mining production and is widely used in various underground mines such as coal mines and metal mines. The car stopper inside the cage is a safety locking device installed inside the mine hoisting cage. When the mine car enters the cage, the car stopper is used to fix and limit the mine car, preventing it from moving forward or backward, deviating or even slipping due to inertia during the hoisting, descent or start-stop of the cage. This ensures the safe operation of the hoisting system, prevents the cage structure from being damaged by impact, and protects the safety of personnel and equipment inside the cage. The existing car stoppers installed inside the cage are in relatively fixed positions, but the wheelbases of the mine cars used in actual use are different. As a result, the fixed car stoppers cannot effectively restrain mine cars with different wheelbases to the predetermined positions. Consequently, when the cage moves, the mine cars will move back and forth a small distance inside the cage, which reduces the stability of the mine cars when the cage moves. Utility Model Content

[0003] The purpose of this invention is to provide an adjustable wheelbase cage car stop, which aims to solve the problem that the existing car stop installed in the cage has a relatively fixed position, but the wheelbase of the mine cars in actual use is different. As a result, the fixed car stop cannot effectively restrain the mine cars with different wheelbases in the predetermined position, and the mine cars will move back and forth a small distance in the cage when the cage moves, resulting in a decrease in the stability of the mine cars when the cage moves.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an adjustable-wheelbase cage-type internal vehicle stopper, comprising a cage body, an abutting pneumatic vehicle stopper body on the inner wall surface of the cage body, a threaded block welded to the bottom surface of the pneumatic vehicle stopper body, a threaded groove formed on the surface of the threaded block, a bidirectional lead screw threadedly connected to the surface of the threaded groove, a bearing sleeved on one side surface of the bidirectional lead screw, the bearing being installed at the bottom of the cage body, a servo motor mounted on the surface of the cage body, a bidirectional lead screw connected to the output end surface of the servo motor, the servo motor being electrically connected to a control panel via a controller, the control panel being installed on the surface of the cage body, a moving groove formed on the inner wall surface of the cage body, a sliding rod connected to the surface of the moving groove, a slider slidably connected to the surface of the sliding rod, the top surface of the slider being welded to the bottom of the pneumatic vehicle stopper body, a first fixing block welded to the surface of the cage body, and a first connecting block rotatably connected to the surface of the first fixing block via a rotating shaft.

[0005] As a preferred embodiment of the adjustable wheelbase cage internal brake of this utility model, two threaded blocks are symmetrically distributed on the surface of the bidirectional lead screw, and the threaded blocks, threaded grooves and bidirectional lead screw form a threaded connection structure.

[0006] As a preferred embodiment of the adjustable wheelbase cage internal vehicle stopper of this utility model, the threaded block and the slider are symmetrically distributed at the bottom of the pneumatic vehicle stopper body.

[0007] As a preferred embodiment of the adjustable wheelbase cage internal vehicle stopper of this utility model, the other side surface of the first connecting block is welded to the surface of the limiting frame, the other side surface of the limiting frame has a slot, the slot surface is inserted into the plug block, and the other side surface of the plug block is adhered to the buffer pad.

[0008] As a preferred embodiment of the adjustable wheelbase cage internal vehicle stopper of this utility model, the surface of the limiting frame is connected to a second connecting block, the surface of the second connecting block is threadedly connected to a threaded rod, the surface of the threaded rod is threadedly connected to a second fixing block, and the second fixing block is welded to the surface of the cage body.

[0009] As a preferred embodiment of the adjustable wheelbase cage internal vehicle stopper of this utility model, the insert is a "T"-shaped integrated structure, the shape and size of which are adapted to the slot.

[0010] Compared with the prior art, the beneficial effects of this utility model are: The servo motor installed on the cage body controls the rotation of the bidirectional lead screw, thereby driving the threaded blocks at the bottom of the two pneumatic car stoppers to move on the cage body. This allows the distance between the two pneumatic car stoppers to be adjusted according to the wheelbase of the mine car to be fixed, so as to stabilize and fix the position of mine cars with different wheelbases in the cage body. In addition, the combination of the rotating shafts and "L"-shaped threaded rods connected to both sides of the limiting frame allows for quick fixing and opening of the limiting frames on both sides of the cage body, thus facilitating the rapid exposure of the opening end of the cage body and making it easier for the moving mine car to enter. At the same time, the buffer pads inserted on the limiting frame buffer the rigid collision between the mine car and the limiting frame, extending its service life. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figures 1-6This utility model provides the following technical solution: an adjustable wheelbase cage internal vehicle stopper, including a cage body 1, a pneumatic vehicle stopper body 2 abutting the inner wall surface of the cage body 1, a threaded block 3 welded to the bottom surface of the pneumatic vehicle stopper body 2, a threaded groove 4 formed on the surface of the threaded block 3, a bidirectional lead screw 5 threadedly connected to the surface of the threaded groove 4, a bearing 6 sleeved on one side surface of the bidirectional lead screw 5, the bearing 6 installed at the bottom of the cage body 1, a servo motor 7 installed on the surface of the cage body 1, the bidirectional lead screw 5 connected to the output end surface of the servo motor 7, the servo motor 7 electrically connected to a control panel 8 via a controller, the control panel 8 installed on the surface of the cage body 1, and the cage... A movable groove 9 is formed on the inner wall surface of the main body 1. A sliding rod 10 is connected to the surface of the movable groove 9. A slider 11 is slidably connected to the surface of the sliding rod 10. The top surface of the slider 11 is welded to the bottom of the pneumatic vehicle stopper body 2. A first fixing block 12 is welded to the surface of the cage body 1. The surface of the first fixing block 12 is rotatably connected to the first connecting block 14 by a rotating shaft 13. In this design scheme, the cage body 1 and the pneumatic vehicle stopper body 2 constitute the cage and the vehicle stopper body. A large number of related components are set in the cage and the vehicle stopper body. Since they are existing technologies and the core content of this technical solution is irrelevant to them, they will not be described in detail in this technical solution. In use: Driven by the pneumatic system installed on the surface of the pneumatic car stopper body 2, the movement of the rail-clamping components on both sides is controlled. When the mine car enters the cage body 1 and is in place, the pneumatic device is activated, pushing the rail clamps to clamp in the direction of the track, "grabbing" the mine car wheels or the track from both sides, forming a mechanical lock, and restricting the mine car from moving back and forth in the cage body 1; when it is necessary to release the mine car, the pneumatic system moves in the opposite direction, the rail clamps are released, and the mine car can drive out of the cage body 1 along the track.

[0015] Preferably, two threaded blocks 3 are symmetrically distributed on the surface of the bidirectional lead screw 5, and the threaded blocks 3, the threaded grooves 4, and the bidirectional lead screw 5 form a threaded connection structure.

[0016] In practical use, when the bidirectional lead screw 5 rotates, the threaded blocks 3 symmetrically distributed on both sides drive the pneumatic brake bodies 2 on both sides to move and adjust their positions on the inner wall of the cage body 1 through the threaded grooves 4 connected by threads.

[0017] Preferably, the threaded block 3 and the slider 11 are symmetrically distributed at the bottom of the pneumatic brake body 2.

[0018] In practical use, when the bidirectional lead screw 5 rotates, the threaded blocks 3 symmetrically distributed on both sides drive the pneumatic wheel stop body 2 on both sides to move and adjust its position on the inner wall of the cage body 1 through the threaded grooves 4 connected by threads. At the same time, the slider 11 connected to the other side of the bottom of the pneumatic wheel stop body 2 slides on the surface of the slide rod 10, so that the pneumatic wheel stop body 2 can move in parallel and stably on the surface of the cage body 1.

[0019] Preferably, the other side surface of the first connecting block 14 is welded to the surface of the limiting frame 15, the other side surface of the limiting frame 15 has a slot 16, the surface of the slot 16 is inserted into the plug 17, and the other side surface of the plug 17 is bonded to the buffer pad 18.

[0020] In practical use, the buffer pad 18 can be fixed to one side of the limit frame 15 by inserting the surface-connected plug 17 through the slot 16 on the surface of the limit frame 15, thereby avoiding rigid collision between the mine car and the limit frame 15 inside the cage body 1.

[0021] Preferably, the surface of the limiting frame 15 is connected to the second connecting block 19, the surface of the second connecting block 19 is threadedly connected to the threaded rod 20, the surface of the threaded rod 20 is threadedly connected to the second fixing block 21, and the second fixing block 21 is welded to the surface of the cage body 1.

[0022] In practical use, hold the horizontal end handle of the "L"-shaped threaded rod 20 and rotate the threaded rod 20, which is threaded between the second connecting block 19 and the second fixing block 21, upwards, so that the thread structure at the longitudinal end of the threaded rod 20 disengages from the threaded groove at the intersection of the second connecting block 19 and the second fixing block 21.

[0023] Preferably, the insert 17 is a "T"-shaped integrated structure, and its shape and size are adapted to the slot 16.

[0024] In practical use, the buffer pad 18 can be inserted and fixed to one side of the limit frame 15 by the slot 16 opened on the surface of the limit frame 15 through the insert block 17 connected to the surface, so as to facilitate the replacement and fixation of the buffer pad 18.

[0025] Working principle: When it is necessary to move the mine car using the cage body 1, hold the horizontal end handle of the "L"-shaped threaded rod 20 and rotate the threaded rod 20, which is threaded between the second connecting block 19 and the second fixing block 21, upwards. This causes the threaded structure at the longitudinal end of the threaded rod 20 to disengage from the threaded groove at the intersection of the second connecting block 19 and the second fixing block 21. Then, pull the limiting frame 15 so that the rotating shaft 13 connected to its other side can drive the limiting frame 15 to rotate outwards and open, thus exposing the opening end on the surface of the cage body 1. At this time, the mine car can be docked on the track on the surface of the cage body 1, thereby pushing the cage body 1 parallel into the cage body 1 and reaching the specified range. Then, the operating parameters of the servo motor 7 are set through the control panel 8, and the movement is adjusted according to the movement into the cage. The servo motor 7 is set to operate based on the wheelbase of the mine car inside the main body 1. Then, the servo motor 7 is started to drive the connected bidirectional lead screw 5 to rotate in the bearing 6. When the bidirectional lead screw 5 rotates, the threaded blocks 3 symmetrically distributed on both sides drive the pneumatic car stop body 2 on both sides to move and adjust its position on the inner wall of the cage body 1 through the threaded groove 4. At the same time, the slider 11 connected to the other side of the bottom of the pneumatic car stop body 2 slides on the surface of the slide rod 10, so that the pneumatic car stop body 2 can move parallel and stably on the surface of the cage body 1 until the rail-holding component on the surface of the pneumatic car stop body 2 can abut against the wheels or rails on both sides of the mine car. At this time, the servo motor 7 stops running and the bidirectional lead screw 5 is locked by the electromagnetic controller, thereby fixing and limiting the position of the mine car. At this point, repeat the above operation again, hold the limit frame 15 and rotate it in the opposite direction to push the limit frame 15 to close on the surface of the cage body 1. At the same time, the buffer pad 18 fixed on the limit frame 15 abuts against the surface of the mine car, providing flexible buffering between the limit frame 15 and the mine car, avoiding rigid collision between the limit frame 15 and the mine car when the cage body 1 moves, which would cause deformation and damage to both, thus extending their service life. Then, the second connecting block 19 connected to one side of the limit frame 15 closed on the cage body 1 is inserted into the rectangular cavity on the surface of the "U"-shaped second fixing block 21. At this time, the threaded through groove at the intersection of the second connecting block 19 and the second fixing block 21 is connected together, so that the threaded rod 20 can be connected together again using the threaded structure on the longitudinal end surface. In this design, the servo motor 7 is the 80ST-H23020-EX-380V-MA model of the existing equipment. It is a mine explosion-proof permanent magnet servo motor that can achieve precise forward and reverse rotation control. The forward and reverse rotation of the servo motor 7 can be controlled by the control panel 8 and the connected controller, thereby adjusting the pneumatic car stop body 2 on the bidirectional lead screw 5 to move to both sides and release the limit control on the mine car. The insert block 17 and the buffer pad 18 are both made of natural rubber, which has the characteristics of good elasticity, wear resistance and effective shock absorption.
