Description

Technical Field

[0001] The utility model relates to the technical field of cable laying, in particular to a high and low voltage cable laying mechanism for a power distribution room. Background Art

[0002] In the current distribution room cable laying practice, high and low voltage cable laying mechanisms generally lack the function of remote control intermittent transmission, which brings significant inconvenience and risks to on-site construction. Traditional manual control is not only inefficient, but also prone to operating errors in complex environments, resulting in cable damage. For example, when laying cables in a small space, due to limited vision, it is difficult for operators to accurately judge the real-time position and status of the cables, thereby increasing the risk of cable twisting, breaking, or even short circuiting. In addition, continuous manual operation may also cause the operator to consume too much physical energy, reduce work efficiency, and may cause safety accidents due to fatigue.

[0003] The operation mode of the existing cable laying mechanism places high physical and technical requirements on the construction workers. During the laying process, the weight and length of the cable often require multiple workers to work together to complete, which not only increases the labor cost, but also limits the construction progress. What's more serious is that if the operation is improper, the cable may suddenly accelerate or decelerate, causing the cable to loosen or tighten, which in turn causes accidents such as falls and trips of construction workers, posing a threat to personal safety. Therefore, improving the operational convenience of the cable laying mechanism and reducing dependence on manpower have become the key to improving construction safety and efficiency.

[0004] One problem that cannot be ignored is that the existing cable laying mechanisms generally do not have an effective one-way locking mechanism, which has caused the problem of cable retraction in practical applications. During the cable laying process, once the traction stops, the cable tends to retract due to its own weight and elasticity. This will not only cause the position of the already laid cable to shift and increase the complexity of readjustment, but also cause friction between the cable and the laying channel in some cases, damaging the cable sheath and affecting the service life and safety of the cable. The cable retraction phenomenon is particularly obvious when laying long-distance and large-diameter cables, which increases the difficulty of construction and reduces the laying accuracy, becoming one of the important factors restricting the efficiency of cable laying.

[0005] Therefore, how to provide a high and low voltage cable laying mechanism for a power distribution room is a problem that technical personnel in this field need to solve urgently. Utility Model Content
