Construction method for large equipment hoisting tail sliding rail

Abstract

The invention relates to a construction method for a large equipment hoisting tail sliding rail. The hoisting tail sliding rail consists of a concrete bearing platform, a rail supporting bottom plate, a guide limit structure and a sliding plate. The hoisting tail sliding rail consists of the concrete bearing platform (1), embedded angle steel (2), a reinforcement net (3), a concrete cushion layer (4), the sliding plate (5), channel steel (6), a reinforcing rib plate (7) and the rail supporting bottom plate (8). The guide limit structure can ensure a hoisting tail to slide along a predetermined track. The sliding plate is the core part of the hoisting tail sliding rail, and can reduce a tractive force needed by the slippage of the large equipment hoisting tail because of small surface friction coefficient of the sliding plate.

Description

Technical field: [0001] The invention relates to a construction method of a sliding track, in particular to a construction method of a sliding track for hoisting and hoisting tail rows of large equipment. Background technique: [0002] At present, the "slip method" is one of the most commonly used methods for hoisting large-scale equipment. The main hoisting crane stands near the equipment foundation to hoist the head of the equipment, and the tail of the equipment is placed on the hoisting tail row. During hoisting, with the lifting of the main crane, the hoisting tail row moves along the special sliding track to the direction of the equipment foundation under the action of the traction force of the special traction block group, gradually erecting the equipment. There are two traditional hoisting and sliding methods as follows: one is to place rollers on the track, and the hoisting tail row moves forward on the rollers through the rolling of the rollers. Because the rollin...

Problems solved by technology

Therefore, the traditional hoisting and slipping method requires a large traction force due to the large friction coefficient. When the lifting weight of the tail row is large, the traction force often cannot meet the requirements.
