Description

Technical Field

[0001] The utility model belongs to the technical field of electric power engineering, and in particular relates to a traction machine for electric power engineering. Background Art

[0002] Cable conveyor is an electric machine for laying power cables (or communication cables). It can be used in conjunction with cable traction machines, hoists and other cable laying machines. The construction is convenient and fast, which can greatly save manpower and material resources, thereby effectively reducing construction costs. Cable conveyor is suitable for large-scale urban power grid transformation, suitable for large-section and long-distance cable laying, reducing labor intensity and improving construction quality. Cable conveyor has large thrust, small size, light weight and easy operation. It is used in cable pipes, tunnels, straight lines, long-distance transportation and other occasions.

[0003] A Chinese patent document with publication number: CN207658846U discloses a cable traction machine for electric power engineering, comprising a base plate, positioning bolts are arranged at the edges of both ends of the base plate, a frame is arranged at the center of the upper surface of the base plate, a motor is arranged above the frame, a driving shaft is arranged at one end of the motor, the driving shaft is connected to the driven shaft through a transmission belt, the driven shaft is located at both ends of a rope winding shaft, and a rope winding baffle is sleeved on the outer wall of the rope winding shaft; the device is welded with a manual turning rod on the outer wall of the rope winding baffle, so that when the device cannot be connected to the power supply in some special places, the device can be used by rotating the manual turning rod to pull the cable, thereby improving the application scope of the device; the device is provided with an auxiliary anti-slip cone on the lower surface of the base plate, which can increase the friction between the device and the ground, and prevent the device from being displaced during traction work, thereby affecting the traction work.

[0004] However, in actual use, it was found that although the setting of the manual turning rod enables manual operation of the device and improves the scope of application, the rope winding shaft can also support the rotation of the inclined rod relative to the device when the device is stationary. This causes external factors to easily accidentally trigger the manual turning rod and drive the rope winding shaft to rotate, affecting the traction of the cable. Utility Model Content
