Problems solved by technology

[0002] In the process of cable laying, it is generally necessary to fix a traction head at one end of the cable, and then connect the traction head with the external power to provide traction for the cable; and the laying of the cable is not only in the sky but also in the ground or in the trench. , if there is a trip during the traction process, many problems will occur. Therefore, the connection strength between the traction head and the cable is very important. In addition, in the existing traction process, the utilization rate of the traction head is low, and it is often a one-time of

Abstract

The invention discloses a traction head for a cable, and the head comprises a first fixing cylinder, wherein a locking unit is arranged in the first fixing cylinder; the locking unit comprises a rotary cylinder rotatably and movably arranged in the first fixed cylinder and a limit sleeve movably arranged in the first fixed cylinder, one end of the rotary cylinder is fixedly connected with the limit sleeve by a locking spring, and the other end of the rotary cylinder is provided with a fixing device for fixing a cable. The invention makes the traction head adapt to the traction work of the cable with small size change under the condition of ensuring the traction of the cable so that the traction head can be reused and the utilization rate of the cable is improved.

Description

technical field [0001] The invention relates to the technical field of cable pulling devices, in particular to a pulling head for cables. Background technique [0002] In the process of cable laying, it is generally necessary to fix a traction head at one end of the cable, and then connect the traction head with the external power to provide traction for the cable; and the laying of the cable is not only in the sky but also in the ground or in the trench. , if there is a trip during the traction process, many problems will occur. Therefore, the connection strength between the traction head and the cable is very important. In addition, in the existing traction process, the utilization rate of the traction head is low, and it is often a one-time of. Contents of the invention [0003] In view of the above-mentioned technical deficiencies, the purpose of the present invention is to provide a pulling head for cables, so that the pulling head can adapt to the pulling work of ca...
