Problems solved by technology

[0002] The spreader is an important part of the crane when it is working. The existing crane spreader is prone to cross-winding when the steel wire rope is working, which leads to the instability and slippage of the lifted heavy objects in the air, which greatly reduces the lifting efficiency and prolongs the production period. Delaying the progress of the project may even lead to serious safety accidents. In order to improve the hoisting efficiency, shorten the project cycle, and create greater benefits for the enterprise, it is necessary to develop a drum pulley spreader with no crossing and no angle between the ropes.

Abstract

The invention relates to a coiling block pulley sling with ropes without intersection or included angles. The coiling block pulley sling comprises a sling body. Two pulley blocks consistent in specification are symmetrically arranged on the left side and the right side of the upper portion of the sling body. Each of the pulley blocks comprises a pulley A, a pulley B and a supporting block, wherein a pin shaft A is arranged on the top of the supporting block, a rotation support is arranged on the outer side of the pulley A, a fixing clamp A is arranged at the lower portion of the pin shaft A, and a limiting clamp is arranged on the right side of the pulley A. Two grabbing devices consistent in specification are symmetrically arranged on the left side and the right side of the middle portion of the sling body. The grabbing devices comprise connecting plates symmetrically arranged on the two sides of the sling body, and pin shafts B are arranged in the centers of the connecting plates. The coiling block pulley sling has the beneficial effects of being simple in structure, convenient to use, reliable in running and low in cost.

Description

technical field [0001] The invention relates to a crane spreader, in particular to a drum pulley spreader with no intersecting ropes and no included angle. Background technique [0002] The spreader is an important part of the crane when it is working. The existing crane spreader is prone to cross-winding when the steel wire rope is working, which leads to the instability and slippage of the lifted heavy objects in the air, which greatly reduces the lifting efficiency and prolongs the production period. Delaying the progress of the project may even lead to serious safety accidents. In order to improve the hoisting efficiency, shorten the project cycle, and create greater benefits for the enterprise, it is necessary to develop a drum pulley spreader with no crossing and no angle between the ropes. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art, and provide a drum pulley spreader with simple structure, ...
