Description

Technical Field

[0001] This utility model relates to the field of cable car pulley technology, and in particular to a pulley assembly for cable car cars. Background Technology

[0002] The cable car pulley assembly is a crucial component of the cableway system, ensuring the smooth and safe movement of the car along the steel cable. This assembly primarily consists of pulleys, axles, bearings, housings, and possibly hooks or shackles. Pulleys are typically made of wear-resistant and high-strength materials, such as aluminum alloys or cast steel, to ensure long-term reliability and safety.

[0003] The pulley assembly is connected to the axle via bearings, allowing the pulley to rotate freely on the steel cable. When the cableway drive system is activated, the drive wheel contacts the steel cable, propelling the cable to rotate through friction. Since the steel cable is continuous, the rotation of the drive wheel drives the entire cable, thus causing the suspended carriages to move accordingly.

[0004] In practical applications, cable car pulley assemblies have certain limitations. Specifically, the locking system of a single pulley assembly often lacks sufficient flexibility and is difficult to adapt to pulley cylinders of different diameters. This design deficiency may lead to unsatisfactory locking performance, thereby affecting the overall safety and stability of the cableway.

[0005] Furthermore, the repair and replacement of fixed pulley systems and locking mechanisms are quite cumbersome after damage. This is because these components are usually installed in concealed or hard-to-reach locations, and their complex structure requires maintenance personnel to spend more time and effort to repair or replace them. This not only increases maintenance costs but may also affect the normal operation of the cableway and the passenger travel experience. Utility Model Content

[0006] The main objective of this invention is to provide a pulley assembly for cable car cabins, which can effectively solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A pulley assembly for a cable car includes a fixed frame, a pulley cylinder, and a support member, wherein the pulley cylinder is mounted on two fixed frames via the support member;

[0009] Each of the fixed brackets has a first sliding groove and a second sliding groove on its end face. A first fastener is inserted into the groove of the first sliding groove, and a second fastener is inserted into the groove of the second sliding groove. The two fixed brackets are fixed by the first fastener and the second fastener.

[0010] The first fastener has a protruding tube on its side wall, and a connecting rod is inserted into the protruding tube. The upper end of the connecting rod is limited and connected to a clamping rod, and the lower end of the connecting rod is connected to a hydraulic cylinder. The side wall of the hydraulic cylinder is provided with a lateral support, and the hydraulic cylinder is fixed to the fixed frame through the lateral support. The hydraulic cylinder drives the connecting rod to push the clamping rod toward the opening of the pulley cylinder, thereby achieving the clamping and locking of the transmission rope at the pulley cylinder.

[0011] In an optional embodiment of this application, a sliding sleeve is fitted on the second fastener, and the outer wall of the sliding sleeve is an arc-shaped groove. The arc-shaped groove is directly opposite the opening of the pulley cylinder, and the transmission rope on the pulley cylinder passes through the arc-shaped groove and reduces wear through the sliding sleeve.

[0012] In an optional embodiment of this application, both the first fastener and the second fastener include a fastening screw, a fastening nut, and an anti-slip washer. The fastening screw passes through the first or second slide groove and is secured by the fastening nut and the anti-slip washer. Anti-slip rubber strips are provided at the openings of the first and second slide grooves.

[0013] In an optional embodiment of this application, the first fastener and the protruding tube are designed as an integral part, and the protruding tube is located in the middle section of the first fastener and is designed perpendicular to it. The connecting rod and the clamping rod are connected by a T-key and a T-hole for limiting. The clamping rod and the connecting rod are perpendicular to each other. The connecting rod is connected to the telescopic end of the hydraulic cylinder by a bolt.

[0014] In an optional embodiment of this application, the lateral support has a U-shaped cross-section and is fixed to the hydraulic cylinder and the fixed frame with screws. Anti-slip plates are provided at the connection between the lateral support, the fixed frame, and the hydraulic cylinder.

[0015] In an optional embodiment of this application, two second slide grooves are symmetrically arranged on both sides of the end face of the fixed frame, forming an isosceles triangle design with the first slide groove. The first fastener and the second fastener are adjusted along the slide groove to adapt to pulleys of different diameters.

[0016] In an optional embodiment of this application, the pulley cylinder is an I-shaped cylinder, and the support member is mounted on a fixed frame via bearings. Nuts are provided at both ends of the support member to connect it to the fixed frame.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] Driven by a hydraulic cylinder, the clamping mechanism precisely clamps and secures the transmission rope on the pulley drum, ensuring both high efficiency and safety of the transmission. During cable car operation, the stability and reliability of the transmission rope are crucial. The clamping mechanism effectively prevents the transmission rope from loosening or falling off, thus guaranteeing the smooth operation of the cable car.

[0019] The sliding sleeve design effectively reduces wear on the transmission rope. The outer wall of the sliding sleeve is designed with an arc-shaped groove, which faces the opening of the pulley cylinder. The transmission rope passes through this arc-shaped groove, forming good lubrication and support between it and the sliding sleeve, thereby extending the service life of the transmission rope and pulley assembly.

[0020] The combined use of the clamping mechanism and the sliding sleeve improves the applicability and flexibility of the pulley assembly. By adjusting the positions of the clamping mechanism and the sliding sleeve, pulleys of different diameters can be accommodated. This design flexibility allows the pulley assembly to be widely used in various cableway systems, greatly improving work efficiency and economic benefits. Attached Figure Description
