Steel wire rope supporting device

Abstract

The invention discloses a steel wire rope supporting device. The steel wire rope supporting device comprises a rope supporting device body (2) and an installing support (3). The rope supporting device body (2) comprises bolt shafts (4), gaskets (5), a roll shaft (6) and bearings (7). The two ends of the roll shaft (6) are installed on the bearings (7) through the bolt shafts (4). The bearings (7) are installed on the installing support (3). The installing support (3) is fixed to a tower crane steel structure (1). A steel wire rope passes the roll shaft (6), and the roll shaft (6) rotates on the installing support (3) with the bolt shafts (4) as axes. According to the steel wire rope supporting device, the roll shaft can rotate on the installing support, the steel wire rope makes contact with the installing support but not make direct contact with the tower crane steel structure, the contact time between the steel wire rope and the roll shaft is short, the contact area between the steel wire rope and the roll shaft is small, and abrasion of the steel wire rope is greatly reduced.

Description

technical field [0001] The invention relates to a tower crane, in particular to a wire rope supporting device. Background technique [0002] The existing tower cranes are aimed at the use of steel wire ropes. Due to the lack of wire rope anti-wear and rope support devices, although theoretically the steel wire rope will not directly contact the steel structure of the tower crane under stress and tension, there will be a long time in the actual use process. , Long-distance direct contact with the steel structure of the tower crane, so the steel wire rope is easy to wear during use, so the following technical disadvantages will appear: [0003] 1. The wire rope wears fast, and the cost of use and maintenance is high. Due to the lack of wire rope anti-wear devices, the wire rope wears fast, reducing its service life, increasing the frequency of regular inspection and maintenance of the wire rope and replacing the wire rope, resulting in increased use and maintenance costs for ...

Problems solved by technology

[0002] The existing tower cranes are aimed at the use of steel wire ropes. Due to the lack of wire rope anti-wear and rope support devices, although theoretically the steel wire rope will not directly contact the steel structure of the tower crane under stress and tension, there will be a long time in the actual use process. , Long-distance direct contact with the steel structure of the tower crane, so the steel wire rope is easy to wear during use, so the following technical disadvantages will appear:

[0003] 1. The wire rope wears fast, and the cost of use and maintenance is high

Due to the lack of wire rope anti-wear devices, the wire rope wears fast, reducing its service life, increasing the frequency of regular inspection and maintenance of wire ropes and replacing wire ropes, resulting in increased use and maintenance costs for users

[0004] 2. High potential safety hazard

Because the wire rope wears fast, and the wear may be uneven and uncontrollable, it will cause the wire rope to be used with a problem, thus posing a safety hazard
