Description

Technical Field

[0001] The utility model relates to the technical field of power transmission and transformation engineering, in particular to a power transmission and transformation engineering line transmission device. Background Art

[0002] The power transmission and transformation project refers to the process of converting and distributing electricity through substations on transmission lines when the high-voltage electricity generated by power plants is delivered to users. It mainly includes two parts: transmission and transformation. Transmission refers to the transmission of electric energy from power plants to various substations, while transformation refers to the conversion, control, monitoring, protection and other processing of electric energy in substations to meet the needs of different power grids and finally transmit it to users when laying lines. Line transmission devices are needed when laying lines. When line transmission devices are used in traditional power transmission and transformation projects, the wire harnesses may be scattered due to vibrations and other reasons during the transmission process, and finally they need to be manually sorted, affecting the construction efficiency of laying lines in power transmission and transformation projects.

[0003] The publication (announcement) number is CN220754195U, which discloses a line conveying device for power transmission and transformation engineering, including a box body, a slide groove is provided at the bottom of the inner wall of the box body, a slider is slidably connected inside the slide groove, a bottom plate is fixedly connected to the top of the slider, a threading block is provided at the top of the bottom plate, a pillar is slidably connected inside the threading block, a limit block is fixedly connected to the top of the pillar, a clamping block is fixedly connected to the bottom of the pillar, a spring is provided on the outer wall of the pillar, and both ends of the spring are fixed between the threading block and the clamping block. In the utility model, the effect of fixing the wire harness head is achieved through the cooperation between the floor, the threading block, the clamping block, the pillar, the spring, and the limit block, which solves the problem that the wire harness may be scattered due to vibration and other reasons during the transportation process, and finally needs to be manually sorted, which affects the efficiency of laying the line in the power transmission and transformation engineering, and improves the efficiency of laying the line in the power transmission and transformation engineering.

[0004] Although the above scheme avoids the unraveling of the wire harness and improves the convenience of packaging and transportation after the line is wound up, when the wire reel is fixed, the card plate that limits its end face can only slide into the slot for placement without limitation. The equipment's limiting effect on the winding component is generally easy to fall and shake, causing the line to become loose. The packaging and calling operations of the winding component require the cooperation of multiple hydraulic rods and a large number of hinged parts. The equipment's packaging and calling operation structure for the winding component has high operating costs. We propose a line transportation device for power transmission and transformation projects. Utility Model Content
