Automatic booster device for adjusting the back tie rod of the miter gate

Abstract

An automatic booster device for adjusting the back pull rod of a miter gate, the device includes a hydraulic pump station, a jack and a portable control box, the jack is connected to the hydraulic pump station through a hydraulic hose, and the portable control box is connected to the hydraulic pump through a cable The hydraulic pump station includes a dual output port oil pump and a pressure sensor; the portable control box includes a programmable controller, and the programmable controller is connected to the operation touch screen and the frequency converter through signal lines. In the present invention, the dual-output port oil pump is used to discharge the oil, which is respectively connected with two jacks, so that two points can be synchronized, stable and balanced; the hydraulic pump is driven by a frequency conversion motor, and the loading speed can be flexibly adjusted; it is controlled by a programmable controller. , It can automatically add force to the force point of the two jacks.

Description

technical field [0001] The invention belongs to the technical field related to the adjustment of the back tie rod of the miter gate of a ship lock, in particular to an automatic force adding device for adjusting the back tie rod of the miter gate. Background technique [0002] The miter gate is a kind of working gate that is widely used in ship locks. Generally, a prestressed back tie rod is installed on the back of the gate to increase the torsional rigidity of the gate body. The size of the prestress should be within the range specified in the design. At present, the known booster device for adjusting the back tie rod of the miter gate is mainly applied by manpower. The stress monitoring of the back tie rod in the process of adding force needs to use a separate stress monitoring system. The adjustment process of the back tie rod of the miter gate is complicated and labor-intensive. Large and long construction period. Contents of the invention [0003] In order to overco...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the disadvantages of complex adjustment process, high labor intensity and long construction period of the existing miter gate back tie rod, the present invention provides a synchronous balance of output force, which can realize automatic force addition and is easy to operate for the adjustment of the back tie rod of the miter gate. automatic booster
