[0002] With the rapid development of urban construction, the demand for power and communication networks is increasing, and cable laying has become more frequent and complex. Traditional cable laying methods usually require a lot of manpower for handling and laying, which is not only inefficient, but also labor-intensive and has high safety risks. In addition, in narrow or crowded urban environments, traditional methods often fail to meet the requirements of fast and accurate cable laying.

[0003] In order to solve the above problems, various cable pay-off devices have appeared on the market, such as manual reels, electric reel vehicles, and automatic pay-off devices with hydraulic systems. These devices have improved the speed and safety of cable laying to a certain extent, but there are still some shortcomings. For example, some devices are large and heavy, making it inconvenient to move in complex terrain; while some small devices are light but have limited carrying capacity and cannot meet the needs of laying long-distance and large-diameter cables.

[0013] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0014] like Figure 1~Figure 2 A cable unwinding device is shown, comprising: two end brackets 1, a connecting frame 2, and a rotating shaft 3. The end bracket 1 is a triangular support frame, and the bottom of the end bracket 1 is a tripod. Its vertical support structure is also a triangular support structure, which is very stable when supporting a heavy-loaded cable reel. Three universal wheels 4 for walking are provided on the lower side of the end bracket 1, and a lifting device 6 is also provided on the cross bar 5 at the bottom of the end bracket 1. The lifting device 6 can adopt a hydraulic cylinder, the piston rod of the hydraulic cylinder is downward, and a support plate is provided at the lower end of the piston rod. The hydraulic cylinder can be started synchronously to lift the entire end bracket 1.

[0015] The two end brackets 1 are symmetrically arranged, and a liftable bearing seat 8 is provided at the top of the end bracket 1. The lifting method can be conventional hydraulic lifting or screw lifting. The connecting frame 2 is fixedly connected to one side of the lower part of the end bracket 1, and a movable frame 7 is provided on the other side of the lower part of the end bracket 1. The connecting frame 2 is arranged parallel to the movable frame 7. The connecting frame 2 and the movable frame 7 connect and fix the two end brackets 1 into a whole.
