Quick lifting mechanism applied to bridge construction

Abstract

The invention discloses a quick lifting mechanism applied to bridge construction. The quick lifting mechanism comprises a movable rack, a motor crawler belt assembly and a hanging basket. The A trussis fixedly mounted on the top of the movable rack. The motor crawler belt assembly is fixedly mounted on the outer wall of the top of the movable rack. The outer wall of the end of the movable rack ishinged to the outer wall of the middle portion of a supporting frame. The upper half portion of the supporting frame is internally provided with sliding grooves. Wire ropes are wound on the outer walls of winding wheels and are attached to the outer walls of guide wheels. The hanging basket is fixed to the lower ends of the wire ropes. The edges of the ends of the movable rack are fixedly connected with locating tubes. The quick lifting mechanism applied to bridge construction facilitates position movement and change and positioning operation. The positioning and installation stability and efficiency of the mechanism are improved. Meanwhile, the quick lifting mechanism can be protected against falling in the using process. Potential construction safety hazards of the quick lifting mechanism during lifting motion are effectively reduced.

Description

technical field [0001] The invention relates to the technical field related to bridge construction, in particular to a rapid lifting mechanism applied to bridge construction. Background technique [0002] The existing bridge construction, according to the different construction techniques, is mainly divided into two types: form pouring construction and prefabricated assembly construction. In different types of construction, it is necessary to install a lifting mechanism to complete the construction of the bridge. Operation, to avoid the omission of bottom reinforcement and the inconvenience of construction operation during the construction of the bridge. At the same time, the use of the lifting mechanism can facilitate the construction and reinforcement of the bridge bottom structure, as well as the installation and positioning of bridge construction accessories. [0003] However, the existing rapid lifting mechanism applied to bridge construction has the following problems ...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide a kind of rapid lifting mechanism that is applied to bridge construction, to solve the above-mentioned background technology, it is inconvenient to artificially adjust the installation and use position of the existing rapid lifting mechanism that is applied to bridge construction when it is in use. Adjustment changes and limit positions make the mechanism prone to overall tilting and shaking due to unilateral force during use, resulting in overall shaking and falling of the materials and accessories it lifts. At the same time, there are serious construction safety hazards. At the same time, when the mechanism During the lifting operation, the limit protection measures are not good, and it is easy to cause local damage to the components during the lifting work, resulting in the rapid fall of the lifted components and materials under the action of gravity, causing the personal safety of the construction personnel to be threatened by the construction , the problem of not being able to effectively buffer and limit the speed of gravity falling
