Problems solved by technology

[0002] At present, during the construction process of the construction site, the nozzles reserved by the main body need to be placed in the later secondary structure construction before installation. As time goes by and in the later cross-construction process, the traditional method is to protect the nozzles with PVC pipes. Add mortar to fill the pipe mouth, but in the actual process, the reserved pipe mouth is often damaged, resulting in pipeline blockage, causing difficulty in unblocking the pipeline after installation, and it will take a lot of manpower, material resources and time to solve this problem in the later stage

Embodiment Construction

[0009] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0010] Such as figure 1 A power supply cable connection locking device for construction machinery is shown, which includes a screw 2 and a steel pipe 1 welded to the screw 2. The inner diameter of the steel pipe 1 is larger than the outer diameter of the pre-embedded pipe.

[0011] Take the 50mm screw 2 and weld the 20mm welded pipe together, and then spray paint. When using, straighten the reserved nozzle, insert the screw 2 into the pre-embedded pipe, and then ge...

Abstract

The invention relates to the technical field of embedded wire pipe opening protection, and particularly discloses a power cable connecting and locking device for building machines. A screw and a steelpipe connected with the screw are included, and the inner diameter of the steel pipe is larger than the outer diameter of an embedded wire pipe. The length of the screw is 20 mm, and the length of the steel pipe is 50 mm. The power cable connecting and locking device has the advantages that a traditional PVC mortar adding filling method is removed, material waste is avoided, the later pipe opening damage possibility is greatly reduced, pipe opening protection mounting and dismounting are simple and convenient, damage caused by improper pipeline protection measures is overcome, materials are saved, and cyclic utilization of the materials is achieved; and cost is saved, finished product protection is improved, manual work is saved, materials are saved, cyclic usage is achieved, and efficiency is higher.

Description

technical field [0001] The invention relates to the technical field of pre-embedded wire pipe opening protection technology, in particular to a power supply cable connection locking device for construction machinery. Background technique [0002] At present, during the construction process of the construction site, the nozzles reserved by the main body need to be placed in the later secondary structure construction before installation. As time goes by and in the later cross-construction process, the traditional method is to protect the nozzles with PVC pipes. Add mortar to fill the nozzle, but in the actual process, the reserved nozzle is often damaged, resulting in pipeline blockage, causing difficulty in unblocking the pipeline after installation, and it takes a lot of manpower, material and time to solve this problem in the later stage. Contents of the invention [0003] The object of the present invention is to provide a power supply cable connection locking device for...
