Description

A positioning device for a dual-circuit hydraulic system

technical field

The utility model relates to the technical field of civil engineering machinery, in particular to a positioning device for a dual-circuit hydraulic system.

Background technique

At present, the anchor cable tensioning and locking methods in China are all locked by the retracting force of the steel wire. In the existing dual-circuit hydraulic system, when the hydraulic outer cylinder stretches the steel strand to the set anchoring force, the hydraulic inner cylinder is activated to press down the bearing plate and push it to the locking plate. There are grooves on the bottom surface of the pressure plate, so that there is still a certain space between the clips on the locking plate and the pressure-bearing plate, so that the clips cannot lock the steel strand on the locking plate, but the retraction force of the anchor cable itself is required. Tighten it, which will cause a large amount of retroactive deformation, so each anchor cable is locked differently and exceeds the international standard. Therefore, the existing technology needs to be developed.

Utility model content

The purpose of the utility model is to overcome the shortcomings existing in the prior art, and to provide a positioning device for a dual-circuit hydraulic system, which aims to solve the problem that the existing anchor cables are locked differently and are prone to large retroactive deformation.

In order to achieve the above object, the utility model provides the following technical solutions:

The utility model provides a positioning device for a dual-circuit hydraulic system, comprising a pressure-bearing plate, a locking plate and a clip, the steel strand passes through the pressure-bearing plate and the locking plate in sequence, and the clip is embedded on the locking plate for clamping the steel strand, wherein the contact surface between the pressure-bearing plate and the locking plate is a plane structure, and the clip includes a pair of half clips arranged separately, The half clips enclose an inverted conical positioning hole.

Further, the locking plate is provided with a mounting hole for installing the half-clamp, and when the pressure-bearing plate is in contact with the locking plate, the half-clamp is accommodated in the positioning hole and clamped. the steel strand.

Further, each of the half clips is provided with an internal thread.

The beneficial effects of the technical solution of the present utility model are:

The positioning device used in the dual-circuit hydraulic system of the present utility model, by setting the contact surface of the pressure-bearing plate and the locking plate into a plane structure, the half-clamps enclose an inverted conical positioning hole, and when the tension reaches the designed anchorage force When the hydraulic inner cylinder pushes the pressure-bearing plate inward, the clip and the steel strand are firmly locked on the locking plate, so as to complete the locking of the anchor cable.
