Description

Technical Field

[0001] This invention relates to roller lugs for mine hoisting containers, and more particularly to a conical sleeve buffer torsion arm and roller lugs. Background Technology

[0002] Mine hoisting containers need to be guided within the shaft to ensure stable operation. While wire rope guides can reduce noise during container operation, they require the shaft structure to be vertical without any offset. The most common guiding method is to equip the shaft with a wire rope guide and use roller lugs for container guidance. Existing torsion arm roller lug structures are relatively simple. After the rollers wear, the angle of the torsion arm changes, which in turn alters the original torsion arm buffer zone, affecting the buffering effect of the torsion arm on the roller lugs. This requires complete disassembly and angle adjustment of the torsion arm to compensate for roller wear, a cumbersome process with poor practicality. Therefore, we propose a conical sleeve buffer torsion arm and roller lug to solve the above problems. Summary of the Invention

[0016] Specifically, the bottom of the L-shaped mounting plate 210 is provided with multiple fastening bolts 211; by using the fastening bolts 211, the L-shaped mounting plate 210 is installed on the top of the mounting base 100, thereby achieving the positioning and installation of the three sets of mounting mechanisms.

A mounting arm 350 is fixed to the top of the outer cylinder 340. By providing a buffer mechanism, a torque is applied to the mounting arm 350 through the support mechanism. The mounting arm 350 and the outer cylinder 340 elastically twist on the inner cylinder 320 through the elastic body 330, which can buffer the movement of the lifting container.

[0018] Specifically, a protective cover plate 240 is provided on one side of the L-shaped mounting plate 210; the protective cover plate 240 is provided to shield and protect the exposed support shaft 310 on one side of the L-shaped mounting plate 210, so as to prevent dust from entering and affecting the stability of the buffer operation.

[0019] Specifically, the fastening mechanism includes a fastening base 410, which is fixed to the top of the mounting arm 350. A pair of mounting rings 420 are provided on the inner wall of the fastening base 410. A fixing pin 421 is slidably connected to the inner wall of each mounting ring 420. A bolt 430 is fixed to the top of each mounting ring 420, and a nut 440 is provided on the outer side of each bolt 430. A pressure block 450 is provided on the top of the fastening base 410.

[0020] Working Principle: In use, the L-shaped mounting plate 210 is installed on top of the mounting base 100 using fastening bolts 211, achieving positioning and installation of the three sets of mounting mechanisms. When installing the buffer mechanism, the mounting studs 230 are passed through the L-shaped mounting plate 210 and the conical chuck 220, and secured with fastening nuts 231 to fix the buffer mechanism. The conical chuck 220 and the inner cylinder 320 have a conical contact structure, creating a tension-type fit between the mounting mechanism and the buffer mechanism. When the mounting studs 230 are tightened, the joint is relatively tight, preventing loosening. The eccentric rollers 530 roll on the guide rail 540, enabling... The movement of the lifting container is supported by applying torque to the mounting arm 350 through the support mechanism. The mounting arm 350 and the outer cylinder 340 elastically twist on the inner cylinder 320 through the elastic body 330, which can buffer the movement of the lifting container. When the eccentric roller 530 wears out after long-term use, the fastening block 450 to the eccentric shaft 510 is loosened, and the eccentric shaft 510 is rotated to a suitable angle. At this time, the gap between the eccentric roller 530 and the guide rail 540 changes under the eccentric action. The change in the rotation radius of the support shaft 310 is used to compensate for the wear gap of the eccentric roller 530, so as to realize the rapid adjustment of the position of the eccentric roller 530.
