Electric pipe wrench for threaded connection of reinforcing steel bar and connecting sleeve

Abstract

The invention discloses an electric pipe wrench for threaded connection of a reinforcing steel bar and a connecting sleeve in a building industry, and belongs to the technical field of reinforcing steel bar connecting devices. The technical scheme includes the electric pipe wrench comprises a shell, a power device, a transmission device, a torque device and a rotating and connecting device, the tightening torque outputted by the power device is transmitted to the rotating and connecting device through the transmission device, the rotating and connecting device realizes orientation rotation of the connecting sleeve through an opening gear and a palate plate, a torque adjusting device can set tightening torque of the connecting sleeve, so that reliable threaded connection is achieved, and overload can be avoided. The electric pipe wrench provides a proper electric tool for threaded connection technology of the thick reinforcing steel bar and the connecting sleeve and has the advantages that a mechanism is small, simple and convenient, the tightening torque can be adjusted, the electric pipe wrench is safe and reliable in running, labor intensity of operators is greatly reduced, working efficiency is remarkably improved, traditional manual operations can be replaced, and the electric pipe wrench is a pioneered and special electric tool in the field of threaded connection of the reinforcing steel bar and the connecting sleeve.

Description

technical field [0001] The invention relates to an electric connecting tool used in the construction industry for threaded connection of steel bars and connecting sleeves, and belongs to the technical field of steel bar connecting equipment. Background technique [0002] The mechanical connection of steel bars is a thick steel bar connection method in the construction industry. When connecting, two steel bars are connected using a connecting sleeve. The connection between the steel bar and the connecting sleeve is through extrusion deformation, wedging between threads, etc. The form is realized. The main ways of connection are: radial and axial extrusion connection (cold extrusion connection), taper thread connection, upsetting straight thread connection, rolling straight thread connection and other forms. The connection between steel bars and connecting sleeves has the advantages of reliable joint performance, stable quality, not affected by climatic conditions, simple pro...

Problems solved by technology

This will greatly hinder the progress of the project, waste time, reduce efficiency, and it is difficult to guarantee the quality of the project

In the past, during the use of these tools, until the worker could no longer twist, because the force of the human arm is different, the steel bar and the connecting sleeve do not all use the same torque to achieve the fastening effect, and the quality of the steel bar connection is stable. Sexuality is greatly influenced by human factors

Most of the damage to the threaded joints occurs at the joints. Now the missing screw or the tightening torque is inaccurate, and the thread is loose, which has a great impact on the strength of the steel bar connection.

Therefore, in order to solve the problems of low work efficiency and difficult torque control, and to ensure the quality of the on-site connection of the connection sleeve, it is necessary to develop a professional tool that can make the connection between the steel bar and the connection sleeve reliable.
