Abstract

The invention provides a tightening wrench device for tightening a sleeve connecting steel bar. The device comprises a tightening shell, a clamping and supporting cylinder, at least three tightening and clamping assemblies and a driving assembly; the clamping and supporting cylinder is rotatably connected in the tightening shell; the at least three tightening and clamping assemblies are arranged in the clamping and supporting cylinder and distributed in the circumferential direction of the clamping and supporting cylinder, all the tightening and clamping assemblies are adjustably connected to the clamping and supporting cylinder in the radial position of the clamping and supporting cylinder, and the tightening and clamping assemblies are used for clamping a to-be-rotated part placed in the clamping and supporting cylinder; and the driving assembly is connected with the clamping and supporting cylinder and used for driving the clamping and supporting cylinder to rotate so as to drive the to-be-rotated part clamped by the tightening and clamping assemblies to rotate, and then tightening between a to-be-fixed part and the to-be-rotated part is achieved. According to the tightening wrench device, to-be-rotated part is clamped through the tightening and clamping assemblies; and the driving assembly drives the clamping and supporting cylinder to rotate so as to drive the to-be-rotated part clamped by the tightening and clamping assemblies to rotate, and tightening between the to-be-rotated part and the to-be-fixed part is achieved.

Description

technical field [0001] The invention relates to the technical field of steel bar installation, in particular to a tightening wrench device for tightening sleeve-connected steel bars. Background technique [0002] At present, in the process of pile foundation construction, building construction, and bridge construction, there are more and more steel members connected by sleeves, and most of the connection operations between sleeves and steel bars use manual steel bar wrenches. The efficiency of using traditional manual steel bar wrenches is relatively low and the labor intensity of workers is high. Even if there is an electric steel bar wrench, it can only be used for short steel bar connections and common specifications of steel bar connections due to site reasons and limitations of the machine itself, and there are potential safety hazards, and It is not easy to tighten, which affects its efficiency. Contents of the invention [0003] In view of this, the present inventi...
