Steel plate pile intelligent pull-out machine special for constructing steel structure bridge cofferdam

Abstract

The invention relates to a steel plate pile intelligent pull-out machine special for constructing a steel structure bridge cofferdam. The pull-out machine comprises a bottom plate. A movable fixing device is installed at the lower end of the bottom plate. An adjusting lifting device is arranged at the upper end of the bottom plate and provided with a pull-out clamping device. A placement box is arranged on the bottom plate and located under the pull-out clamping device. The movable fixing device comprises a movable adjusting mechanisms evenly arranged at the lower end of the bottom plate. Thelower ends of the movable adjusting mechanisms are installed on a movable supporting plate. A fixed telescopic cylinder is installed on the movable supporting plate. The top end of the fixed telescopic cylinder is installed on the bottom plate through a flange. The problems that in an existing bridge cofferdam constructing and steel plate pile detaching process, steel plate piles need to be pulledout manually with the acid of existing device hoisting equipment, the steel plate piles need to be fixed manually, the steel plate piles pulled out need to be conveyed manually, and steel plate pilesdifficult to pull out need to be manually pulled out with the aid of a vibrating tool can be solved.

Description

technical field [0001] The invention relates to the technical field of bridge construction equipment, in particular to an intelligent steel sheet pile extractor for steel structure bridge cofferdam construction. Background technique [0002] The steel sheet pile is a kind of linkage device on the edge, and the linkage device can be freely combined to form a continuous and compact steel structure for retaining soil or water retaining wall. The steel sheet pile is a type of steel with a lock. There are U-shaped and Z-shaped cross sections, and various sizes and interlocking forms. The common ones are Larson type, Lackawanna type and so on. Its advantages are: high strength, easy to drive into hard soil; it can be constructed in deep water, and if necessary, it can be added with oblique supports to form a cage. Good waterproof performance; cofferdams of various shapes can be formed according to needs. It is widely used in the construction of steel structure bridges. The const...

Problems solved by technology

[0003] In order to solve the above problems, the present invention provides a special steel sheet pile intelligent puller for the construction of steel structure bridge cofferdams, which can solve the existing problems in the removal process of steel sheet piles in the existing bridge cofferdams that require manual lifting equipment with the help of existing equipment Pulling out the steel sheet piles requires manual fixing of the steel sheet piles and manual transportation of the pulled steel sheet piles. Difficult-to-pull steel sheet piles need to be pulled out manually with the aid of vibrating tools, and manual pulling out of the steel sheet piles with the help of existing lifting equipment is unstable. , it is necessary to manually adjust the lifting equipment according to the height of the steel sheet pile. Manually fixing the steel sheet pile has poor stability and has potential safety hazards. It is necessary to manually adjust the steel sheet piles of different specifications. The operation is complicated. Manually use vibration tools to assist in pulling out the steel sheet pile It is time-consuming and labor-intensive, and the lifting equipment is troublesome to move. It needs to be fixed manually during the work to prevent sliding and affect the removal of steel sheet piles. It is labor-intensive, time-consuming and low-efficiency. It can realize the steel plate in the construction of bridge cofferdams The function of pile intelligent extraction does not require manual operation, there is no potential safety hazard, and it has the advantages of simple operation, time saving, good stability, high labor intensity and low work efficiency.
