Description

TECHNICAL FIELD

[0001] The present application relates to the field of cable laying equipment, in particular to a cable laying equipment for underground cable construction. BACKGROUND

[0002] Cable laying refers to the process of installing power cables, communication cables and other cables to the predetermined position through a series of steps, which is a key link in the infrastructure construction of power, communication, broadcasting and other fields, and the purpose is to ensure that power or signal can be transmitted safely and stably. Cable laying usually involves selecting appropriate cable types, determining laying methods, performing construction steps and other aspects.

[0003] Cable laying conveyor is a mechanical equipment specially used for cable laying operation, which is usually used in large-scale or long-distance cable laying process. Its main function is to automatically feed the cable from the cable reel into the buried trench or pipeline, simplifying and accelerating the cable laying process, reducing manual labor intensity and improving construction efficiency. The cable laying conveyor is usually connected with a cable reel or cable drum. The cable is drawn out from the cable reel through the conveyor. The conveyor is provided with a conveyor belt or chain system to uniformly feed the cable into the trench or pre-set pipeline. The end of the conveyor is provided with a cable traction device to ensure that the cable is accurately laid to the predetermined position and avoid cable accumulation or irregular laying.

[0004] The cable laying conveyor can automatically adjust the conveying speed according to the type and specification of the cable to ensure that the cable is not damaged during laying. However, in actual construction application of cable laying, due to the complex and diverse construction site conditions, the traction device at the end of the conveyor and the conveyor are not usually working on the same horizontal line. The cable reel is usually placed in an open area. The worker puts the net belt into the head of the cable and then manually pulls the net belt to introduce the head of the cable into the conveyor. At this time, if the conveyor and the traction device are not on the same horizontal line, when the head of the cable is sent out from the conveyor, the worker needs to pull the cable head to change the direction of the cable, and at the same time, the conveyor needs to be coordinated to convey the cable, so that the cable sent out from the conveyor is bent at a certain angle and then introduced into the traction device. Due to the heavy weight of the cable, the process of introducing the cable from the conveyor into the traction device is time-consuming and labor-intensive.

[0005] In the subsequent continuous conveying process of the cable, the rollers of the traditional conveyor are usually located on the upper and lower sides of the cable to limit and support the cable in the vertical direction in a clamping manner. If the cable is bent at a certain angle in the horizontal direction, it will cause the cable to be easily worn and abraded with the brackets at both ends of the roller.
