[0002] A traction vehicle that uses an endless rope as a transmission element in a mine or mining area is a mining endless rope traction vehicle. The endless rope is a steel wire rope. Endless rope traction vehicles are usually used to transport materials such as ore and coal. When the endless rope traction vehicle is running in an undulating tunnel, the floating and pulling of the steel wire rope directly affect the operation of the system and even the safety of the tunnel support. Therefore, in order to prevent the steel wire rope from floating, pulling, and effectively prevent the vehicle from falling off the track, a reliable main rope pressure wheel group must be used, and compulsory rope pressure must be used at the concave points of the track to prevent the steel wire rope from floating. The rope pressure wheel group mainly consists of a base and two staggered rope pressure wheels. The upper end diameter of the rope pressure wheel is larger, and the lower end diameter is smaller. The overall cross-sectional shape is T-shaped. The steel wire rope passes through the smaller diameter and is pressed by the larger diameter upper end, thereby preventing the steel wire rope from floating.
[0003] When the common rope-pressing device of a mining endless rope tractor is in use, the wire rope passes through two staggered rope-pressing wheels and is pressed by the upper end with a larger diameter. However, the wire rope is only pressed by the upper end with a larger diameter. The rope-pressing method is too simple, and the stability and reliability of the rope-pressing need to be improved.

DETAILED DESCRIPTION
[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] See also Figure 1-4 The utility model discloses a rope pressing device for a mine-use endless rope traction vehicle, comprising a base 1 and a steel wire rope 2, and also comprising:
[0024] The rope pressing mechanism 3 includes a sliding seat 33 slidably connected to the base 1, a connecting seat 32 is fixed on the sliding seat 33, a pressing wheel 31 is movably sleeved on the surface of a fixed shaft fixed to the inner wall of the connecting seat 32, and the number of the pressing wheels 31 is two groups, and the steel wire rope 2 passes through the two groups of pressing wheels 31 to achieve rope pressing of the steel wire rope 2, and a guide component 35 is arranged on the side of the connecting seat 32;
[0025] The buffer component 4 is used to buffer the displacement of the rope pressing mechanism 3 caused by the lateral force.
[0026] Specifically, the inner wall of the pressure wheel 31 is a curved surface, and the shape of the pressure wheel 31 is adapted to the shape of the steel wire rope 2 .
[0027] In this implementation plan, please refer to Figure 1 and Figure 3 The inner wall of the pressure wheel 31 is a curved surface, which enables the pressure wheel 31 to stably fit the surface of the wire rope 2, thereby achieving stable rope pressing processing for the wire rope 2 and preventing the wire rope 2 from separating from the pressure wheel 31 when moving sideways.
[0028] Specifically, a triangular block 34 is fixed at the connection position between the connecting seat 32 and the sliding seat 33 , and the triangular block 34 is used to improve the connection strength between the connecting seat 32 and the sliding seat 33 .
[0029] In this implementation plan, please refer to Figure 3 The triangular block 34 is used to increase the contact area between the connecting seat 32 and the sliding seat 33 , thereby improving the connection strength between the connecting seat 32 and the sliding seat 33 .
[0030] Specifically, the buffer assembly 4 includes a spring 42 fixed between the base 1 and the sliding seat 33. A guide column 41 that passes through the base 1 is fixed on the side of the sliding seat 33. The guide column 41 is located inside the spring 42. The elastic force of the spring 42 is used to buffer the lateral displacement of the rope pressing mechanism 3. A guide sleeve 43 is fixed on the side of the base 1. The inner wall of the guide sleeve 43 is slidably connected to the surface of the guide column 41.
[0031] In this implementation plan, please refer to Figure 3 Springs 42 are fixed on both sides of the sliding seat 33, and there are two springs 42 on the same side. When the pressure wheel 31 is subjected to the lateral force generated by the lateral movement of the wire rope 2, the sliding seat 33 will be driven to slide along the inner wall of the base 1, and the sliding seat 33 will squeeze the spring 42. The compression deformation of the spring 42 will buffer the lateral movement and provide space for the lateral movement of the pressure wheel 31 and the sliding seat 33. When the sliding seat 33 moves, it drives the guide column 41 to move along the inner wall of the guide sleeve 43, and the guide column 41 guides the movement of the sliding seat 33. When the lateral movement force of the wire rope 2 disappears, the sliding seat 33 and the pressure wheel 31 automatically return to their original positions under the elastic force of the spring 42.
[0032] Specifically, a guide block 44 is fixed to the bottom of the sliding seat 33 and moves laterally along the inner wall of the base 1 . The guide block 44 is used to improve the guiding ability of the sliding seat 33 .
[0033] In this implementation plan, please refer to Figure 4 The guide block 44 is used to further guide the movement of the sliding seat 33, thereby improving the guiding ability of the sliding seat 33.
[0034] Specifically, the guide block 44 is in an isosceles trapezoidal shape, and is used to improve the guiding stability of the sliding seat 33 during the movement.
[0035] In this implementation plan, please refer to Figure 4 The contact area between the guide block 44 and the inner wall of the base 1 is increased by the isosceles trapezoid, thereby improving the guiding stability of the sliding seat 33 during the movement.
[0036] Specifically, the guide assembly 35 includes a connection block 351 fixed to the side of the connection seat 32 and a guide ring 352 fixed to the end of the connection block 351 , and the wire rope 2 passes through the middle of the guide ring 352 .
[0037] In this implementation plan, please refer to Figure 1 and Figure 4 The connecting block 351 is used to connect and fix the guide ring 352 and the connecting seat 32. The wire rope 2 passes through the middle of the guide ring 352. The cooperation between the guide ring 352 and the pressure wheel 31 realizes the stable rope pressing processing of the wire rope 2.
[0038] The working principle and use process of the utility model are as follows: the wire rope 2 is passed through the front guide ring 352, and then passed through the middle of the two groups of pressure wheels 31 and then passed out from the rear guide ring 352. The inner wall of the pressure wheel 31 is a curved surface, which can make the pressure wheel 31 stably fit the surface of the wire rope 2. The stable rope pressing process of the wire rope 2 is achieved through the cooperation of the guide assembly 35 and the two groups of pressure wheels 31, so that the rope pressing of the wire rope 2 is more stable and reliable. When the wire rope 2 moves, it drives the pressure wheel 31 to rotate with the fixed axis in the connecting seat 32 as the axis. The rotation of the pressure wheel 31 reduces the friction between the wire rope 2 and the wire rope 2, so that the movement of the wire rope 2 is smoother.
[0039] When the pressure wheel 31 is subjected to the lateral force generated by the lateral movement of the wire rope 2, the pressure wheel 31 drives the sliding seat 33 to slide along the inner wall of the base 1 through the connecting seat 32, and the sliding seat 33 squeezes the spring 42. The compression deformation of the spring 42 buffers the lateral movement and provides space for the lateral movement of the pressure wheel 31 and the sliding seat 33. When the sliding seat 33 moves, it drives the guide column 41 to move along the inner wall of the guide sleeve 43. At the same time, the sliding seat 33 drives the guide block 44 to slide along the inner wall of the base 1. The cooperation between the guide column 41 and the guide block 44 makes the movement of the sliding seat 33 smoother and smoother. When the lateral movement force of the wire rope 2 disappears, the sliding seat 33 and the pressure wheel 31 automatically return to their original positions under the elastic force of the spring 42.
[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
