Lifting appliance suitable for tackle for paying-off

Abstract

The invention discloses a lifting appliance suitable for a tackle for paying off. The lifting appliance suitable for the tackle for paying off comprises a cross beam, a connecting mechanism and multiple grasping mechanisms, wherein the upper end part of the cross beam is connected with an external hoisting device through the connecting mechanism; the multiple grasping mechanisms are uniformly arranged from left to right and comprise load-bearing connecting pieces, load-bearing chains, grasp frames and catchers; the load-bearing connecting pieces are connected with the lower end part of the cross beam; the upper end parts of the load-bearing chains are fixedly connected with the load-bearing connecting pieces; the lower end parts of the load-bearing chains are fixedly connected with the upper end parts of the grasp frames; the catchers comprise left grasp parts and right grasp parts; the left grasp parts and the right grasp parts are matched with a pulley of the tackle for paying-off; the left grasp parts are rotatably connected with the left ends of the grasp frames; and the right grasp parts are rotatably connected with the right ends of the grasp frames. According to the liftingappliance suitable for the tackle for paying off provided by the invention, the lifting speed of the tackle for paying off is accelerated.

Description

technical field [0001] The invention relates to the technical field of hoisting devices, in particular to a hoist suitable for a pay-off tackle. Background technique [0002] Pay-off pulley is a commonly used construction equipment in the tension pay-off construction process of power transmission and transformation projects. Different, there are φ508, φ660, φ820, φ916 and other varieties. like figure 1 and figure 2 As shown, the pay-off tackle includes a pay-off tackle hanging plate 1, a pay-off tackle frame 2 and a pay-off tackle pulley 3. [0003] In the construction of line engineering, the use of pay-off blocks is large, and the block itself has a special shape, which brings difficulties for loading and unloading transportation. Ordinary hoisting speed is slow, and personnel workload is big, therefore, need badly a kind of special-purpose spreader of loading and unloading transport pay-off block. Contents of the invention [0004] The object of the present invent...

Problems solved by technology

[0003] In the construction of line engineering, the use of pay-off blocks is large, and the block itself has a special shape, which brings difficulties for loading, unloading and transportation.

Ordinary hoisting speed is slow, and the workload of personnel is heavy. Therefore, there is an urgent need for a special spreader for loading, unloading, and transporting pay-off blocks.
