Extruding and extending device for sectional Y-shaped extruded and extended pile

Abstract

The compaction expanding equipment for making compaction expanded pile is characterized by that one end of its connector is connected with crane, another end is passed through the centre of rotating device and connected with compaction expanding machine head, its two oil pipes are connected with hydraulic work station and pressure sensor and flow sensor of electronic measurement control device. Said invented compaction expanding machine head possesses upper and lower two identical oil cylinder and lower compaction oil cylinder, and the oil pipes are placed in the piston rod as central lever. The angular transducer and motion transducer are placed on the ground, and between all the components of connector there is a gap. Said equipment is high in working efficiency, and good in reliability.

Description

Technical field: [0001] The present invention relates to an extruding and expanding device for reinforced concrete piles of buildings, bridges or various foundations, in particular to an extruding and expanding device for multi-section three-prong extruded and expanded piles, which can be used for bridge piles, floor piles, slope protection piles, and high-pressure anchor rods. Wait. Background technique: [0002] Chinese patent CN98102841.1 fully intelligent multifunctional hydraulic extrusion device, although it has an epoch-making improvement compared with the current extrusion device, it rarely breaks down and greatly improves work efficiency, but because the device uses many oil pipes, it is difficult to rotate the oil cylinder. The sealing conditions of the positioning cylinder and the positioning cylinder are relatively high, so problems are prone to occur; the positioning device can successfully complete the positioning when the soil layer is good, but it cannot achi...

Problems solved by technology

[0002] Chinese patent CN98102841.1 fully intelligent multifunctional hydraulic extrusion device, although it has an epoch-making improvement compared with the current extrusion device, it rarely breaks down and greatly improves work efficiency, but because the device uses many oil pipes, it is difficult to rotate the oil cylinder. The sealing conditions of the positioning cylinder and the positioning cylinder are relatively high, so problems are prone to occur; the positioning device can successfully complete the positioning when the soil layer is good, but it cannot achieve good positioning when the soil layer is poor; in addition, the positioning device and the squeezed and expanded The height difference between the bow pressing arms is 2-3m. When the shorter piles are squeezed and expanded, there will be no positioning space, and the device is squeezed and expanded in the horizontal direction. In fact, it also moves up and down, due to the hard bottom and soft top. , if the device floats up, it will be invalid for positioning; moreover, because one oil cylinder is used to complete two bidirectional movements during extrusion, the lower piston must have three moving seals, which will greatly shorten the life of the components, and installation and processing Both are very difficult; in addition, the reliability of the pressure sensor and the displacement sensor is greatly reduced due to the harsh conditions when they work in the hole, and the addition of a set of cables leads to cumbersome control and poor reliability, etc.
