Description

Technical Field

[0001] This utility model relates to the field of floor roller technology, and in particular to a support roller with an external high-performance liner. Background Technology

[0002] Ground rollers, also known as ground pulleys or ground sheaves, are devices installed at the bottom of overhead crane shafts. They primarily function as fixed pulleys, using leverage to lift and lower drilling equipment and brine-collecting devices. In inclined shafts of coal mines, ground rollers are indispensable equipment, mainly used to support and guide wire ropes, ensuring their smooth operation. They are typically placed in the middle of the track, one every 7-15 meters, and used in conjunction with the hoist and sheave. Common types of ground rollers include rubber ground rollers, nylon ground rollers, polyurethane ground rollers, and cast steel ground rollers.

[0003] When existing rollers are in use, the wire rope usually slides in one position on the roller surface, causing the roller surface to be subjected to force and wear in only one position for a long time. This results in uneven wear on different parts of the roller surface, reducing the overall utilization efficiency of the roller and increasing maintenance costs.

[0004] To address the aforementioned issues, a support roller with an external high-performance liner is proposed. Utility Model Content

[0005] The main purpose of this invention is to provide a support roller with an external high-performance pad, which solves the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved by adopting the following technical solution:

[0007] A support roller with an external high-performance padding includes a ground roller body, on which a roller shell made of polyurethane material is provided, a metal mandrel is fixed through the inside of the roller shell, a support mechanism is provided outside the mandrel, and an adjustment mechanism is provided at the bottom of the support mechanism.

[0008] The supporting mechanism includes a bearing body that is installed in conjunction with the spindle. A bearing cover is detachably connected to the outer periphery of the bearing body. A support plate is provided around the outer periphery of the bearing cover. A support rod is screwed between the inner sidewalls of the support plate. A drive slider is integrally formed at the bottom of the support rod.

[0009] The adjustment mechanism includes a lead screw threadedly connected to the slider. Fixed plates are rotatably nested at both ends of the non-threaded surface of the lead screw. Track grooves are fixedly connected to both ends of the fixed plates. A stepper motor is fitted to one end of the lead screw.

[0010] Furthermore, the mandrel is also fitted with a high-performance gasket for connecting the inner wall of the roller shell. The high-performance gasket is made of phenolic resin with fabric reinforcement.

[0011] Furthermore, the bearing cover is a split structure, and the ear plate of the bearing cover is fixedly connected to the top of the support plate by short bolts.

[0012] Furthermore, the support rod is provided with slide rails on both sides that are bolted to the inner sidewall of the support plate, and the slide rails slide within the track groove.

[0013] Furthermore, symmetrical wire rope limiting grooves are fixed on the inner wall of the track groove, and several U-shaped grooves are opened on the wire rope limiting grooves, the width of which is greater than the diameter of the wire rope.

[0014] Furthermore, the contact surface between the stepper motor and the fixed plate is detachably mounted via a slot.

[0015] The beneficial technical effects of this utility model are as follows:

[0016] This invention utilizes a support mechanism and an adjustment mechanism. Through the cyclic forward and reverse rotation of a drive motor, the lead screw drives the support plate and the roller body to reciprocate on the track groove. The steel wire rope on the roller body, pulled by the steel wire rope limiting groove, also reciprocates on the roller surface of the roller body, maintaining contact with the roller surface. This ensures that the roller surface of the roller body receives uniform downward pressure from the steel wire rope, preventing the steel wire rope from rubbing against the roller surface in one position for a long time, thereby improving the service life of the roller.

[0023] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0024] like Figures 1-4 As shown, this embodiment provides a support roller with an external high-performance pad, including a roller body 1. The roller body 1 is provided with a roller shell 101 formed by processing polyurethane material. A metal spindle 102 is fixedly fixed inside the roller shell 101. A support mechanism 2 is provided outside the spindle 102. An adjustment mechanism 3 is provided at the bottom of the support mechanism 2. The support mechanism 2 includes a bearing body 203 that is installed in conjunction with the spindle 102. A bearing cover 202 is detachably connected to the outside of the bearing body 203. A support plate 201 is provided around the bearing cover 202. A support rod 204 is screwed between the inner sidewalls of the support plate 201. A drive slider 205 is integrally formed at the bottom of the support rod 204. The adjustment mechanism 3 includes a lead screw 304 that is threadedly connected to the slider. Fixed plates 302 are rotatably nested at both ends of the non-threaded surface of the lead screw 304. Track grooves 301 are fixedly connected to both ends of the fixed plate 302. A stepper motor 303 is installed at one end of the lead screw 304.

[0025] In the above structure, the surface layer of the roller made of polyurethane material has good wear resistance and provides good protection for the wire rope.

[0026] The core shaft 102 is also fitted with a high-performance gasket for connecting the inner wall of the roller shell 101. The high-performance gasket is made of phenolic resin with fabric reinforcement. The connecting layer made of phenolic resin with fabric reinforcement can be firmly bonded to the metal shaft that is the core of the roller, and can also be firmly bonded to polyurethane and reduce the overall weight of the roller.

[0027] The bearing cover 202 is a split structure. The ear plate of the bearing cover 202 is fixedly connected to the top of the support plate 201 by short bolts. The bearing body 203 is fixedly nested on the spindle 102. The bearing cover 202 is also fixedly sleeved with the bearing body 203, which is fixed to the support mechanism 2 to ensure the stable rotation of the floor roller.

[0028] The support rod 204 is provided with slide rails 206 on both sides, which are bolted to the inner sidewall of the support plate 201. The slide rails 206 slide in a limited manner with the track groove 301. The track groove 301 is fixed to the ground. The two ends of the track groove 301 are open to facilitate the reciprocating sliding of the slide rails 206.

[0029] Symmetrical wire rope limiting grooves 305 are fixed on the inner side wall of the track groove 301. Several U-shaped grooves are opened on the wire rope limiting grooves 305. The width of the U-shaped grooves is larger than the diameter of the wire rope. According to the number of wire ropes carried on the ground roller, they are fixed and introduced into the wire rope limiting grooves 305. The wire rope limiting grooves 305 do not affect the normal sliding of the wire rope, but only maintain the left and right pulling and traction of the wire rope during reciprocating movement.

[0030] The contact surface between the stepper motor 303 and the fixed plate 302 is detachably installed via a slot. The stepper motor 303 is controlled by an external control mechanism and rotates in both directions under a set working sequence, thereby driving the floor roller body 1 to move back and forth.

[0031] The working principle of this device is as follows: When in use, this device is connected to an external power supply and an external control device.

[0032] After the wire rope passes around the roller shell 101, it passes through the wire rope limiting groove 305 at the bottom. The stepper motor 303 has its working speed and forward / reverse cycle set by an external control device. The stepper motor 303 drives the lead screw 304 to rotate, which in turn drives the drive slider 205, support rod 204, support plate 201, and slide rail 206 to move synchronously. The slide rail 206 moves in a limited and guided manner within the track groove 301, causing the entire roller body 1 to move laterally along the track groove 301. The slider moves forward by 1 / 3 of the length of the roller shell 101, starting from the center of the roller shell 101. The total moving distance is 2 / 3 of the length of the roller shell 101. As the roller shell 101 moves, the wire rope is limited and pulled in the wire rope limiting groove 305, sliding on the roller shell 101 and making uniform contact with multiple surfaces on the roller shell 101.

[0033] By adopting the above structure, pressure is not applied to only one position on the roller surface when the wire rope slides on the roller for a long time. This avoids the situation where the same position wears out for a long time while other positions do not wear out or wear is not obvious, thus preventing the roller from being scrapped and replaced. This achieves the purpose of extending the service life of the roller.

[0034] The above are merely further embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed by this utility model, based on the technical solution and concept of this utility model, shall fall within the protection scope of this utility model.
