Movable sling for mounting expansion joint of comb plate

Abstract

The invention discloses a movable sling for mounting an expansion joint of a comb plate. The movable sling mainly comprises a sling framework and transmission parts such as a lifting hook, a winch, a fastening inhaul cable, a movable inhaul cable, a fixed pulley and a universal wheel serving as finished products, wherein the sling framework consists of a weighting bracing plate, a support arm, a support upright column, a suspension arm, a rear arm, a reinforcing pipe and a fastening member; the movable sling is driven by power and is mechanically lifted to construct. The movable sling is driven by the power and is lifted mechanically so as to efficiently convey the comb plate in a time-saving and labor-saving mode; the comb plate is lifted by the sling and is manually positioned, so that each splicing plate block is positioned accurately; the personal safety problem caused by manually carrying can be avoided by adopting mechanical lifting; a minitype crane can be replaced by the movable sling, so that the economic cost is saved to a large extent; and the movable sling is simple, light and small in size.

Description

technical field [0001] The invention relates to a mobile hanger for installing comb-tooth plate expansion joints. Background technique [0002] At present, there are two main problems in the installation of the known comb-tooth plate expansion joints: one is that due to the heavy weight of each spliced ​​plate and the limitation of manpower, it becomes difficult to manually transport, lift, and put the comb-tooth plate in place. Very difficult, poor precision, and not safe. Second, if a small crane is used, it is very uneconomical, the accuracy is difficult to control, and the road has been cut off, making it difficult and inconvenient for the crane to move. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies of the prior art, the purpose of the invention is to provide a mobile spreader for installation of comb plate expansion joints. [0004] Technical solution: In order to solve the above technical problems, the technical ...
