Problems solved by technology

[0003] During the construction process, the operator may constantly pull the power cord to reach different work areas due to the needs of the work, which often causes the power cord and the socket device to loosen, causing unexpected interruption to the work
This kind of interruption will not only reduce the construction efficiency and bring inconvenience to the operator, but also in some more important work occasions, this unexpected power interruption will cause safety accidents

Abstract

The invention discloses a power line connecting and locking device capable of being conveniently and fast disassembled, assembled and maintained for construction machinery. The power line connecting and locking device comprises a device frame body (9) and a drive motor (16), wherein the drive motor (16) is fixed in the device frame body (9); a power line inserting channel (50) is arranged in the device frame body (9) for inserting a power line (5); the drive motor (16) is in power connection with a screw rod (161) which extends downwards from the drive motor (16); an external spline (162) and an internal spline (163) are arranged at the connected part of the drive motor (16) and the screw rod (161); a drive wedge block (10) is in screw-thread fit on the screw rod (161); and the wedge-shaped surface on the right side of the drive wedge block (10) and the inclined plane in a main body (151) of a locking slide block (15) which can slide left and right on a carrying and locking slide block (12) are in sliding fit.

Description

technical field [0001] The present application relates to the field of construction machinery, in particular to a power cord connection locking device for construction machinery that is easy to disassemble and maintain. Background technique [0002] In the process of building construction, some movable machinery is usually used, such as some grinders, eye drills and some movable power tools. These machines require a larger operating range or radius and typically have longer power cords. [0003] During the construction process, the operator may constantly pull the power cord to reach different work areas due to the needs of the work, which often causes the power cord and the socket device to loosen, causing unexpected interruption to the work. This interruption will not only reduce the construction efficiency and bring inconvenience to the operator, but also in some more important work occasions, this unexpected power interruption will cause safety accidents.
