Shaft-distance-adjustable double-shaft synchronous fastening device capable of realizing operation without power cut

Abstract

The invention relates to a shaft-distance-adjustable double-shaft synchronous fastening device, which comprises a motor, a striking shaft, a first output shaft and a second output shaft, wherein the motor applies force onto the striking shaft for rotation by driving a striking block; a first striking gear and a second striking gear are arranged on the striking shaft in a sleeving way; a spring is arranged in an interval position between the two gears; the two striking gears respectively and correspondingly drive a first output gear and a second output gear in the vertical direction; the outer part of the first output gear and the outer part of the second output gear are correspondingly connected with the first output shaft and the second output shaft; the output shafts respectively drive a replaceable sleeve; the second striking gear and the second output gear are connected through a connecting block by matching a bearing; the second striking gear, the second output gear and the connecting block synchronously move through a threaded rotating element. The double-shaft synchronous fastening device has the advantages that during the installation of double screw nut fastening hardware such as insulation piercing connectors without power cut, two fastening screw nuts can be enabled to be synchronously screwed down; the gap between the two output shafts is adjustable; sleeve components arranged on the output shafts can also be replaced, so that the double-shaft synchronous fastening device can be applicable to hardware in different specifications.

Description

technical field [0001] The invention relates to the field of installation tools for cable equipment, in particular to a double-axis synchronous fastening device with adjustable wheelbase for non-stop operation. Background technique [0002] The fittings used on power lines, such as 10kV insulation piercing clamps, are fastened with double nuts. The insulation piercing clamps are suitable for connecting insulated wires. They are mainly composed of insulating shells, piercing blades, waterproof rubber pads, and torque bolts. When the cable is branched, insert the branch cable into the branch cap and determine the branch position of the main line, then use a socket wrench to tighten the torque nut on the clamp. With the tightening of the torque nut, the upper and lower parts of the clamp have piercing blades The insulator is gradually closed, and at the same time, the arc-shaped sealing rubber pad wrapped around the puncture blade is gradually clinging to the cable insulation l...

AI Technical Summary

Problems solved by technology

[0004] In actual work, it is difficult to ensure that the two nuts are tightened synchronously or alternately due to the awareness of the operator or the limitation of the working tools. For example, the asynchronous tightening of the insulating puncture wire clamp will cause the puncture blade to skew the needle, resulting in poor puncture effect. The flow rate cannot meet the requirements, and the temperature rise is high during operation, which will cause burning and disconnection in severe cases
