Abstract

A pair of portable hydraulic pliers for crimping bead string joints relates to a pair of portable hydraulic pliers and aims to solve the problems that no appropriate crimping operation tool is available for conventional crimping of bead string joints, a crimping force cannot be controlled within a reasonable range, and accordingly the connection between a bead string joint and a bead string is not stable. The pair of portable hydraulic pliers comprises a jaw, a pliers pump body, an oil inlet component, a compressing component, an oil draining component, a pressure setting component, an oil receiver, a main handle, a pressurizing moving handle, a pressure unlocking handle, a pressure measuring valve, an elastic load-bearing pin, crimping modules and pin shafts, wherein a first blind hole and a second blind hole are processed in two ends of the pliers pump body respectively; the oil receiver is sleeved with the main handle; the compressing component is mounted on the pliers pump body; the jaw is fixedly mounted on the compressing component; the crimping modules are mounted on the jaw in a sliding way; the pressure setting component is mounted in the second blind hole; the oil inlet component is mounted on the pliers pump body; and the oil draining component is fixedly mounted on the pliers pump body. The pair of portable hydraulic pliers is used in the field of crimping of bead string joints.

Description

technical field [0001] The invention relates to a hydraulic pliers, in particular to a portable hydraulic pliers for crimping beaded rope joints. Background technique [0002] Before the wire saw machine works, it is necessary to connect the two ends of the beaded rope together to form a closed loop through the beaded rope joint, and then install the beaded rope on the sheave. Beaded rope joints mostly use steel metal joints. Due to the high hardness of steel metal materials, it is not easy to be crimped and formed. Even if the steel metal joints are crimped and formed, the crimping force is difficult to control within a reasonable range. If the relay force is too small, one end of the beaded rope will come out from the beaded rope joint, and if the crimping force is too large, the beaded rope joint will be crushed or have tiny cracks, which will affect the stability of the connection between the beaded rope joint and the beaded rope. At present, most of the compression pli...
