High-speed dismantling equipment for urban underground pipe gallery steel sheet piles

Abstract

The invention discloses high-speed dismantling equipment for urban underground pipe gallery steel sheet piles. The equipment comprises a mounting seat; a hydraulic machine is fixedly connected with the mounting seat; a lifting frame is fixedly connected with a hydraulic rod; a vertical plate is fixedly connected with the mounting seat; a groove matched with the lifting frame is formed in the vertical plate; a clamping block is slidably connected with the lifting frame; a blocking block is fixedly connected with the vertical plate; the blocking block is abutted against the clamping block; a first clamping plate and a second clamping plate are rotatably connected with the interior of the clamping block; a first gear is fixedly connected with the first clamping plate; a first rack is fixedly connected with the lifting frame; the first rack is meshed with the first gear; a circular plate is fixedly connected with the second clamping plate; a connecting rod is rotatably connected with the circular plate; the end, away from the circular plate, of the connecting rod is rotationally connected with the first gear; and the lifting frame is provided with a transferring mechanism used for transferring the steel sheet piles. According to the high-speed dismantling equipment for the urban underground pipe gallery steel sheet piles, the steel sheet piles can be automatically and continuously removed, manual fixing and conveying are not needed, and the pulled-out steel sheet piles can be cleaned.

Description

technical field [0001] The invention relates to the technical field of construction equipment for pipe gallery construction, in particular to a high-speed demolition device for steel sheet piles in an urban underground pipe gallery. Background technique [0002] Steel sheet pile is a kind of section steel with lock. Its cross-section has straight plate shape, trough shape and Z shape, etc. There are various sizes and interlocking forms. The common ones are Larson type, Lackawanna type, etc. The advantages are: high strength, easy to drive into the hard soil layer; it can be constructed in deep water, and if necessary, it can be added with inclined supports to form a cage. Good waterproof performance; cofferdams of various shapes can be formed according to needs, and can be reused many times, so it has a wide range of uses. [0003] After the project is completed, the steel sheet piles need to be removed, but in the process of removing the existing steel sheet piles, the ste...
