Description

Technical Field

[0001] The utility model relates to the technical field of cable conveying, in particular to a stable cable conveyor with a speed-changing function. Background Art

[0002] As living standards continue to improve, the scale of urban power grids is also expanding. The traditional method of laying cables by hand and shoulder is no longer sufficient. To reduce the labor intensity of cable laying, ensure construction quality, and speed up construction progress, cable conveyors have been developed for various laying scenarios. Cable conveyors are electric machines used to lay power cables (or communication cables). They can be used in conjunction with cable tractors, hoists, and other cable laying equipment. They facilitate and speed construction, significantly saving manpower and material resources, and effectively reducing construction costs.

[0003] The Chinese patent application number CN202321340865.3 in the prior art discloses a cable conveyor that prevents cable damage, including a bracket and a first base body and a second base body arranged side by side; a pitch-adjusting screw rod is rotatably provided on the bracket; the pitch-adjusting screw rod can movably pass through the first base body and the second base body, and is threadedly connected to the first base body, and is used to adjust the distance between the first base body and the second base body under the action of the thread; a first driven rotating shaft and a first active rotating shaft are rotatably provided on the left and right sides of the first base body respectively; a second driven rotating shaft and a second active rotating shaft are rotatably provided on the left and right sides of the second base body respectively; the first The driving shaft, the first driven shaft, the second driving shaft and the second driven shaft are all provided with sprockets; the sprockets of the first driving shaft and the first driven shaft are provided with a first chain; the sprockets of the second driving shaft and the second driven shaft are provided with a second chain; a first crawler is provided on the outside of the first chain; a second crawler is provided on the outside of the second chain; a driving device is provided on the side of the second seat away from the second crawler; the driving device is connected to the second driving shaft to drive the second driving shaft to rotate; the second driving shaft is provided with a flexible synchronous rotation device, which is used to drive the first driving shaft and the second driving shaft to rotate synchronously in opposite directions.

[0004] The above technical solution solves the problem that the cable conveyor is equipped with two motors, one track corresponds to one motor, which is costly. The two tracks on the cable conveyor are arranged horizontally, resulting in a wider overall width of the cable conveyor. In special applications, such as when laying three cables at a time, a problem occurs in the middle cable and needs to be replaced. Because the cable conveyor is relatively wide, it cannot be placed between the two cables on both sides to replace the middle cable. However, it requires an external power supply, and during use, the conveying speed cannot be controlled and cannot be adjusted according to the needs of use. When laying multiple cables, if affected by external factors, the cables will be entangled, thereby affecting the normal laying of the cables. For this reason, we propose a stable cable conveyor with a variable speed function. Utility Model Content
