Control system for bolt fastening device

Abstract

The invention discloses a control system for a bolt fastening device. The bolt fastening device comprises a support, an execution unit and a travelling unit, wherein the execution unit is installed onthe support and is used for tensioning a bolt in the extending direction of the corresponding bolt and screwing a nut on the corresponding bolt, and the traveling unit is arranged on the support andis used for driving the bolt fastening device to travel along paths of a plurality of bolts. The control system comprises an execution control module, an advancing control module and a controller, wherein the execution unit is used for controlling the operation of the execution unit, the advancing control module is used for controlling the operation of the advancing unit, and the controller is communicated with the execution control module and the advancing control module so as to command the execution unit to tension the bolt and fasten the nut, and command the travelling unit to advance forwards, so that the bolt fastening device moves to a next bolt after the fastening operation of one bolt is completed. The control system automatically achieves the fastening of the bolts, reduces the manual operation investment, and improves the installation quality.

Description

technical field [0001] The invention relates to the field of bolt installation and fastening, in particular, the invention relates to a control system for a bolt fastening device. Background technique [0002] A MW-level wind turbine is mainly composed of a tower, a main engine, and an impeller. The tower is usually composed of multiple steel tower sections, and the tower section is usually a thin-walled cylindrical structure with ring flanges at both ends. A number of bolt through holes are usually evenly distributed in the circumferential direction on the ring flange, and the connecting bolts, supporting washers and nuts connect adjacent tower sections together through these bolt through holes. [0003] When hoisting the tower section, after installing the bottom tower section on the foundation and aligning the two tower sections, the operator first installs all the bolts at the ring flange and pre-tightens them manually, and then uses hydraulic tension All the bolts are ...

AI Technical Summary

Problems solved by technology

Due to the large number of bolts on the tower flange and the heavy hydraulic tensioner, the workload of on-site personnel is very large

At the same time, every time a bolt is tightened, the equipment needs to be disassembled and reinstalled, which causes a waste of time and reduces the efficiency of on-site installation

In addition, bolts are manually tightened on site, and the quality of bolt installation is not easy to control
