Description

Technical Field

[0001] The utility model relates to a cable car brake mechanism with a three-way limiter, belonging to the technical field of cable cars. Background Art

[0002] During the operation of the tugboat in the port, when towing the ship and mooring, it is necessary to rely on the cable crane to retract and release the cable. The cable crane brake belt is retracted by the hydraulic rod to contact the cable crane, so that the cable crane brake stops rotating. Since the hydraulic rod only acts on one point of the circular brake belt (and most of them are located on the side), the upper part of the brake belt is easy to contact the cable crane due to gravity when the brake belt is not retracted, affecting the normal operation of the cable crane and reducing the service life of the brake belt. When the brake belt is retracted, since the hydraulic rod is pulled on both sides at the same time, due to the uneven tension on both sides, the brake belt has shifted left and right. The above problems will affect the operation of the cable crane and the service life of the brake belt, endangering the safety of the operation and posing a safety hazard.

[0003] The utility model patent with patent application number CN03233737.X discloses an automatic brake safety device for inclined track cable cars when the rope breaks, which includes a wedge box, a gripper, a rocker, a connecting rod, a slider and a disc spring. The gripper can move relatively in the wedge box, and the track is located between the two grippers. The gripper is equipped with a swingable rocker, and the connecting rod connects the rocker and the slider, and the slider is equipped with a disc spring. The gripper is pulled by the traction wire rope. When the rope breaks, the pressure generated by the disc spring forces the gripper to move down quickly and lock the track in the wedge box to brake automatically. The automatic brake safety device only plays a protective role through automatic braking when an accident occurs in the cable car, and cannot play a protective role in the normal operation of the cable car brake structure. Utility Model Content

[0004] The utility model aims to solve the technical problems of short service life and great potential safety hazards of brake belts in the prior art, and provides a cable car brake mechanism with a three-way limiter.

[0005] The utility model is realized by the following technical solutions:

[0006] That is, a cable car brake mechanism with a three-way limiter, comprising a cable machine base and a cable machine body, a cable machine shell is arranged outside the cable machine body, a brake belt is arranged between the cable machine body and the cable machine shell, a circular base is installed on the side of the cable machine base, a three-way limiter base is installed on the circular base, a longitudinal bolt is installed on the three-way limiter base, the inner end of the longitudinal bolt is pressed against the brake belt, and a transverse bolt for tightening the extension block of the brake belt is also installed on the three-way limiter base;

[0007] A hydraulic cylinder is installed at the lower part of the cable car base, and the hydraulic cylinder is hingedly connected to the end of the brake belt through a connecting arm.

[0008] The utility model can ensure that the brake belt of the cable car maintains a distance from the cable car when not working by adjusting bolts through simple structural transformation without changing the original cable car structure, and restricts the brake belt from displacement to the left and right when working, thereby extending the service life of the cable car brake belt and reducing the safety hazards of daily operation of the cable car.

[0009] Further preferably, the connecting arm 1, the connecting arm 2 and the end of the brake band are hinged at the same point.

[0010] Further preferably, the connecting arm 2 is hingedly connected to the side edge of the cable crane base. The brake belt is driven by this structure, which is simple and reliable.

[0011] Further preferably, two longitudinal bolts are installed on the base of the three-way limiter, and the central axis of the longitudinal bolts is parallel to the cable machine body. The two longitudinal bolts support the brake belt, so that the brake belt offsets the gravity and does not contact the cable machine when not working.
