Description

Technical Field

[0001] This invention relates to the field of cable laying technology, and in particular to a tension control device for power dispatching during power grid construction. Background Technology

[0002] Power grid construction is inseparable from cables. A cable is an electrical energy or signal transmission device, typically composed of several or groups of conductors, each group insulated from each other, often twisted around a central conductor, and covered with a highly insulated outer layer. Cables are characterized by internal conductivity and external insulation. They are widely used in many industries, including oil fields and mines, construction, machinery manufacturing, research institutions, ports and docks, shopping malls, hotels, and road and bridge construction. As industrial demands become increasingly diversified, their market share will continue to grow. Currently, during cable laying, the cable is pulled at the construction site, and the reel releases the cable. If the reel releases the cable too quickly, excess cable will be present, resulting in significant tension on the cable and potentially causing the cable outer shell to break, thus affecting the cable laying progress.

[0023] Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, the transmission mechanism includes first limiting seats 10 symmetrically arranged on both sides of the lifting plate 9, a second limiting seat 11 at the bottom of the adjusting frame 5, and an adjusting plate 12 between the first limiting seat 10 and the second limiting seat 11.
