Technical Field
[0001] This utility model belongs to the technical field of mining electromechanical equipment, specifically relating to a wire rope deflection device for underground aerial personnel transport devices. Background Technology
[0002] As a crucial piece of personnel transportation equipment in mines, the safe and stable operation of underground aerial personnel transport systems is of paramount importance. In this field, wire rope misalignment during operation has always been a key factor affecting the normal use of the equipment. Traditional rope support pulley systems have limited adjustment capabilities when faced with localized wire rope wear on the inner edge of the pulley due to installation issues, easily leading to pulley damage and accelerated wire rope wear. This increases spare parts costs and maintenance workload, and also poses a threat to personnel transport safety. Utility Model Content
[0003] The purpose of this invention is to provide a wire rope deflection device for underground aerial personnel transport devices, in order to solve the problem of wire rope deflection and accelerated wear caused by existing rope sheaves.
[0004] This utility model adopts the following technical solution: a wire rope deflection device for underground aerial personnel transport devices, comprising: A rope-supporting pulley has a first annular groove on its body for a steel wire rope to pass through. The axis of the rope-supporting pulley is connected to a bracket via a first rotating shaft, which is perpendicular to the bracket. A first-stage deflector has a second annular groove on its wheel body for a steel wire rope to pass through. Its axis is connected to a mounting block via a second rotating shaft. The mounting block is connected to a bracket via a connecting rod. The second rotating shaft is perpendicular to the connecting rod, and the connecting rod is perpendicular to the bracket. The first annular groove and the second annular groove have their axes coincident, and both the first annular groove and the second annular groove are coaxially provided with annular wheel bushings; the first annular groove is used for the steel wire rope to pass through, and the second annular groove is used for the steel wire rope to be corrected.
[0005] Furthermore, a steel plate is connected to the top of the bracket, and the top of the steel plate is secured to the crossbeam by two U-bolts.
[0006] Furthermore, the mounting block is provided with a waist-shaped groove, through which the second rotating shaft can be detachably connected.
[0007] Furthermore, the bracket is provided with a waist-shaped groove, through which the first rotating shaft can be detachably connected.
[0008] The beneficial effects of this utility model are as follows: By combining the support rope wheel with the deflector wheel, the problem of wire rope deviation and wear on the inner edge of the support rope wheel can be effectively solved, avoiding excessive wear on the edge of the rope groove of the support rope wheel, extending the service life of the support rope wheel, reducing the frequency of equipment parts replacement, and lowering the cost of parts. By solving the problem of wire rope deviation and wear, the safe operation of the aerial personnel transport device is ensured, the safety and continuity of personnel transportation are improved, transportation interruptions caused by equipment failure are avoided, and the normal operation of mine production is guaranteed. This deflector wheel device has low processing cost, low investment, simple installation, strong targeting, and is easy to promote and use in aerial personnel transport devices in underground mines.

[0011] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0012] This utility model provides a wire rope deflection prevention device for underground aerial personnel carriers, such as... Figure 1-3 As shown, it includes: A rope-supporting wheel 5 has a first annular groove 11 on its wheel body for a steel wire rope to pass through. The axis of the rope-supporting wheel 5 is connected to a bracket 3 through a first rotating shaft 9, and the first rotating shaft 9 is perpendicular to the bracket 3. A first-stage deflector 6 has a second annular groove 12 on its wheel body for a steel wire rope to pass through. Its axis is connected to a mounting block 1 via a second rotating shaft 10. The mounting block 1 is connected to a bracket 3 via a connecting rod 2. The second rotating shaft 10 is perpendicular to the connecting rod 2, and the connecting rod 2 is perpendicular to the bracket 3. The first annular groove 11 and the second annular groove 12 have their axes coincident, and both the first annular groove 11 and the second annular groove 12 are coaxially provided with annular wheel bushings; the first annular groove 11 is used for the steel wire rope 7 to pass through, and the second annular groove 12 is used for correcting the deviation of the steel wire rope 7.
[0013] The underground personnel transport system relies on wire ropes for movement. When the wire rope's center of travel does not align with the sheave's center of travel, it can cause jamming and wear on the sheave. In cases where a section of the wire rope cannot be aligned, using a combination of a sheave and a deflector can effectively solve the problem of wire rope misalignment and wear on the sheave's inner edge. This prevents excessive wear on the sheave's groove edge, extends its service life, reduces the frequency of equipment parts replacement, and lowers spare parts costs.
[0014] In some embodiments, a steel plate 4 is connected to the top of the bracket 3, and the top of the steel plate 4 is fastened to the crossbeam 8 by two U-bolts 13. The crossbeam 8 is fixed to the top of the underground tunnel.
[0015] In some embodiments, the mounting block 1 is provided with a waist-shaped groove, through which the second rotating shaft 10 is detachably connected. The waist-shaped groove allows adjustment of the position of the deflector wheel 6 relative to the mounting block 1, facilitating the alignment of the axes of the first annular groove 11 and the second annular groove 12.
[0016] In some embodiments, the bracket 3 is provided with a waist-shaped groove, through which the first rotating shaft 9 is detachably connected. The waist-shaped groove allows adjustment of the position of the rope-supporting wheel 5 relative to the bracket 3, facilitating the alignment of the axes of the first annular groove 11 and the second annular groove 12.
[0017] The method of using the wire rope deflection prevention device for underground aerial passenger transport equipment according to this utility model is as follows: First, inspect the support rope pulleys of the underground personnel carrier system to identify areas where the wire rope is rubbing against the inner edge of the support pulley. Then, prepare for the installation by modifying the existing support rope pulleys where the anti-deviation device needs to be installed. Use the transverse single support pulley as a counterweight, installing it in the appropriate position according to design requirements, ensuring a secure installation that does not interfere with the normal operation of the original system. After installation, test the system, observing whether the wire rope's position is effectively corrected during operation and whether there is still rubbing against the inner edge of the support pulley. If problems are found, promptly fine-tune the position or angle of the transverse single support pulley until the wire rope operates normally, aligns with the center of the support pulley, and no longer rubs against the inner edge of the support pulley. During use, regularly inspect and maintain the system, checking the wear of the transverse single support pulley. If the bushing is severely worn, replace it with a lower-cost support rope pulley bushing to ensure the normal operation of the anti-deviation device. Simultaneously, record the system's usage to facilitate further optimization and improvement.
