Embodiment Construction

[0037] Such as figure 1 The pumping station of a walking jacking system shown includes a pumping station and a general control center. Each pumping station is equipped with a pumping unit including a fuel tank, an integrated valve group, and an oil inlet and outlet. The general control center have:

[0038] (1) Standard setting unit for jacking, pushing, and rectifying displacements, used to input the standard setting values ​​of displacements for jacking, pushing, and rectifying;

[0039] (2) The real-time displacement data of jacking, pushing, and correction is input to the receiving unit, which is used to receive the real-time displacement data of jacking, pushing, and correction operations;

[0040] (3) Jacking, pushing, and correcting control unit, used to compare the received real displacement data during jacking, pushing, and correcting operations with the displacement standard setting values ​​of jacking, pushing, and correcting , if the real-time displacement data d...

Abstract

The invention discloses hydraulic walking pushing system pump stations. A main control center comprises a jacking, pushing and rectifying displacement standard setting unit, a jacking, pushing and rectifying real-time displacement data input receiving unit, a jacking, pushing and rectifying control unit, a jacking, pushing and rectifying executing unit and a PLC automatic control unit, wherein the jacking, pushing and rectifying displacement standard setting unit is used for inputting the displacement standard set values of jacking, pushing and rectifying; and the jacking, pushing and rectifying real-time displacement data input receiving unit is used for receiving real-time displacement data of jacking, pushing and rectifying. The hydraulic walking pushing system pump station has the advantages that the multiple pushing units are subjected to three-dimensional control through one main control system so as to achieve continuous and synchronous working, the control precision is high, and the manpower cost is reduced; the expandability and the universality are high, the pushing units can be increased or decreased by increasing or decreasing the pump stations and jacks, and accordingly the requirements for construction of engineering of different spans and different tonnages are met; components do not need to be temporarily reinforced, equipment can operate till construction is completed after being installed in one time and does not need to be disassembled halfway due to the fact the length of a steel strand is not enough, and the bridge building cost can be reduced; and a dynamic rectifying function is achieved, and the defect that the equipment only can move forwards while cannot move backwards in a common traction mode is overcome.

Description

technical field [0001] The invention relates to a construction machine for engineering, in particular to a pumping station with a walking push system for the overall translation of large components. Background technique [0002] Continuous jacking technology has been more and more widely used in translational construction of large components. For long-span structures such as steel box girder jacking construction of bridges, the existing construction methods generally adopt continuous jacking or dragging, and the steel box girder or concrete girder needs to be temporarily reinforced with external cables, and the bridge is lifted. ;Using the form of steel strand traction, every time a section is pushed, the steel strand needs to be reinstalled. The construction process of this method is cumbersome, the cost is high, and it can only move forward but not backward. At the same time, the horizontal thrust or pulling force of repeated starting is unfavorable to the stress working ...
