Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of coal mine transportation, and more specifically relates to an anti-rope-falling rope-pressing wheel group of an endless rope continuous traction vehicle. Background Art
[0002] The working principle of an endless rope continuous hauling vehicle is that it is driven by an endless rope traction winch, utilizing the friction between the wire rope and the drive wheel to drive the wire rope, thereby enabling the wire rope hauling vehicle to reciprocate along the track. Specifically, after the traction wire rope passes around the friction wheel, one end is fixed to the shuttle car, and the other end passes around the tensioning device, then around the tail wheel, and is again fixed to the shuttle car. The tensioning device tensions the wire rope to give it a certain initial tension. The starting motor drives the active drum, which in turn drives the friction wheel, causing the endless rope and the shuttle car connected to the wire rope to reciprocate, driving the vehicle. During production, due to the long distances and heavy workload of the endless rope transport, the vehicle is often fully loaded. If there is an unexpected increase in resistance such as scratching during operation, the wire rope can fly out of the rope pressure pulley assembly at the slope change point.
[0003] Based on the search of the above patents and the application of the existing endless rope continuous traction vehicle to prevent the rope from falling off, it is understood that the working principle of the original rope pressure wheel group is to rely on two rope clamping wheels. After the shuttle car passes through and knocks the rope wheels open, the spring is used to automatically retract and close the two wheels to control the wire rope. The closing force of the rope pressure wheel is the elastic force of the spring.
[0004] When the rope-pressing wheel assembly is set at the slope change point, when the elastic tension of the wire rope toward the opening direction of the rope-pressing wheel exceeds the elastic force of the rope-pressing wheel closing spring, the wire rope will instantly pop out of the rope-pressing wheel assembly, causing a flying rope accident. Utility Model Content
[0005] In order to solve the above technical problems, the utility model provides an anti-rope-slipping rope pulley group for an endless rope continuous traction vehicle, so as to solve the existing problem that when the rope pulley group is set at the slope change point, the elastic tension of the wire rope toward the opening direction of the rope pulley exceeds the elastic force of the rope pulley closing spring, the wire rope will instantly pop out of the rope pulley group, causing a flying rope accident.
[0006] The technical solution adopted by this utility model is:
[0007] The anti-rope-slipping rope pressure pulley group of the endless rope continuous traction vehicle includes a mounting seat; an adjusting frame is fixedly connected to the top middle position of the mounting seat, and a two-way threaded rod is rotatably connected to the inner middle position of the adjusting frame. The left and right side positions of the adjusting frame are respectively slidably connected to an opposing slider, and a threaded hole is respectively opened at the middle position of the side of each opposing slider, and the left and right side positions of the two-way threaded rod are located in the screw hole of an opposing slider, and the top middle position of each opposing slider is respectively fixedly connected to a mounting block, and the middle position of each mounting block is rotatably connected to a rotating block, and the other end position of each rotating block is rotatably connected to an adaptable block, and a rope pressure pulley body is rotatably installed at the top middle position of each adaptable block.
[0008] According to an embodiment of the present invention, a limit frame is fixedly installed on the left and right sides of the top of the mounting seat respectively. The two limit frames are symmetrically designed, and the adjustment frame is located in the middle of the two limit frames.
[0009] According to an embodiment of the present invention, an elastic telescopic rod is rotatably designed at the inner middle position of each limiting frame, and the outer position of each elastic telescopic rod is installed at the outer middle position of the rotating block.
[0010] According to an embodiment of the present invention, a slide rail is fixedly installed at the top middle position of each of the limit frames, the two slide rails are symmetrically designed, and a limit seat is slidably installed at the upper position of each slide rail.
[0011] According to one embodiment of the present invention, a spiral steel wire piece with a spiral design is connected above the limit seat, and the upper end of the spiral steel wire piece is connected to the lower position of the docking frame. The inner position of each docking frame is fixedly connected to the outer position of the adaptation block.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. By rotating the bidirectional threaded rod, the two rope pressure wheels can be retracted synchronously, effectively limiting the rope to prevent it from escaping and ensuring the convenience of wire rope docking.
[0014] 2. The device is installed at the bottom of the slope. When the shuttle car reaches the bottom of the slope, the rope-pressing wheel body automatically expands outward to allow the shuttle car to pass normally, and then automatically resets to continue fitting the rope. The special design prevents the accident of the wire rope popping out due to elastic tension when the rope-pressing wheel group is set at the slope change point, thereby improving safety.
[0015] 3. Through the connection and coordination between the adaption block and the docking frame, as well as the design of the spiral steel wire, the vibration force generated by the shuttle car passing by is effectively isolated, preventing the resonance effect from affecting the main body of the mounting base.

[0024] The following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings and examples.
[0025] Example 1: As shown in the attached Figure 1 To the attached Figure 4 As shown:
[0026] The utility model provides an anti-rope-slipping rope pressure pulley group for an endless rope continuous traction vehicle, comprising a mounting seat 1; an adjusting frame 2 is fixedly connected to the top middle position of the mounting seat 1, a bidirectional threaded rod 201 is rotatably connected to the inner middle position of the adjusting frame 2, and an opposing slider 202 is slidably connected to the left and right sides of the adjusting frame 2, and a threaded hole is respectively opened at the middle position of the side of each opposing slider 202, and the left and right sides of the bidirectional threaded rod 201 are both located in the screw hole of a opposing slider 202, and a mounting block 203 is fixedly connected to the top middle position of each opposing slider 202, and the middle position of each mounting block 203 is fixedly connected to the top middle position of each opposing slider 202. The middle position of each rotating block 204 is rotatably connected to a rotating block 204, and the other end position of each rotating block 204 is rotatably connected to an adapting block 205. A rope pressure wheel body 206 is rotatably installed at the top middle position of each adapting block 205. A limit frame 101 is fixedly installed on the left and right sides of the top of the mounting base 1. The two limit frames 101 are symmetrically designed, and the adjusting frame 2 is located in the middle position of the two limit frames 101. An elastic telescopic rod 102 is rotatably designed at the inner middle position of each limit frame 101, and the outer position of each elastic telescopic rod 102 is installed at the outer middle position of the rotating block 204.
[0027] Among them, a slide rail 103 is fixedly installed at the top middle position of each limit frame 101, and the two slide rails 103 are symmetrically designed. A limit seat 3 is slidably installed above each slide rail 103, and a spiral steel wire piece 301 with a spiral design is connected to the upper position of the limit seat 3. The upper end position of the spiral steel wire piece 301 is connected to the lower position of the docking frame 303, and the inner position of each docking frame 303 is fixedly connected to the outer position of the adaptation block 205.
[0028] When in use: first place the rope in the middle of the two rope-pressing wheel bodies 206, then rotate the bidirectional threaded rod 201, and the bidirectional threaded rod 201 drives the two opposing sliders 202 to retract synchronously until the inner sides of the two rope-pressing wheel bodies 206 fit the two sides of the rope, limiting the rope to avoid the situation of the wire rope being detached, and ensuring the convenience of the wire rope when docking.
[0029] When the shuttle car has passed the slope change point, the two elastic telescopic rods 102 are extended and reset, driving the upper ends of the two adapting blocks 205 to reset to their initial positions, and the two rope pressing wheel bodies 206 continue to fit the rope, avoiding the situation that when the rope pressing wheel group is set at the slope change point, the elastic tension of the wire rope in the direction of the rope pressing wheel opening exceeds the elastic force of the rope pressing wheel closing spring, the wire rope will instantly pop out of the rope pressing wheel group, and a rope flying accident will occur.
[0030] When the shuttle car passes above the rope-pressing wheel group and contacts the two rope-pressing wheel bodies 206, a vibration force will be generated, and the force will be transmitted to the adaptation block 205. Through the connection and cooperation between the adaptation block 205 and the docking frame 303, the force will be transmitted to the spiral steel wire member 301, which has a vibration isolation effect and prevents the vibration force from being transmitted to the main body of the mounting base 1, causing a resonance effect.
