Cable pulling auxiliary device with self-locking structure

Abstract

The invention discloses a cable pulling auxiliary device with a self-locking structure. The cable pulling auxiliary device comprises a cable pulling supporting frame. The cable pulling supporting frame is provided with two supporting sliding rails which are arranged in a spaced mode, supporting containing grooves are formed in the supporting sliding rails, two limiting idler wheels are installed on the supporting sliding rails, and the limiting idler wheels can rotate relative to supporting pulleys. The rear ends of the supporting sliding rails are connected with entering supports, and the top end faces of the entering supports are inclined. The cable pulling supporting frame is further provided with two mounting frames located on the outer sides of the two supporting sliding rails correspondingly. Mounting through holes are formed in the mounting frames in a penetrating manner, and a locking assembly capable of axially moving and circumferentially rotating relative to the mounting through holes is mounted in one mounting through hole. Each mounting frame is further provided with a mounting frame driving assembly. According to the cable pulling auxiliary device, through the arrangement of the two limiting idler wheels and the locking assembly, on one hand, the rotating gravity center of a cable reel can be effectively lowered, and then efficient and stable cable pulling work can be guaranteed; and on the other hand, the locking assembly is integrated on the cable pulling supporting frame so that the workload of operators can be reduced.

Description

technical field [0001] The invention belongs to the technical field of cable construction, and in particular relates to a wire pulling auxiliary device with a self-locking structure. Background technique [0002] Cable is a necessary material for the construction of power lines, and it is usually wound on a cable drum to enter the construction site in rolls. In order to facilitate the laying-out of cables, the support shaft is usually used to penetrate the cable roll (the cable has been wound on the cable reel), the cable roll is set on the support shaft, and then the support shaft is placed on the wire support frame, and then through a jack or other The drive unit raises the support shaft or the cable support frame to suspend the cable coil, so that the cable can be released. But existing support device (stay wire support frame and support shaft) has following problem: [0003] 1. In the existing cable structure, most of them are equipped with independent support shafts t...

Problems solved by technology

[0003] 1. In the existing cable structure, most of them are equipped with independent support shafts to support the cable reels. In this way, scattered auxiliary structures will not only increase the operating workload of the staff, but also increase the management burden of the staff.

[0004] 2. When the cable reel is suspended in the air by a jack or other driving device, it is easy to cause the shaking of the cable reel, which in turn causes safety risks such as scratching; on the other hand, the high center of the cable reel will also affect the stability of the payout

[0005] 3. The function of the support shaft is mainly to provide the support force for the rotation of the cable reel. In the existing operation, in order to facilitate the penetration of the support shaft, the outer diameter of the support shaft is usually smaller than the support through hole of the cable reel (there is usually a hole on the cable reel for The cable reel that runs through the support shaft), so that under the action of its own weight, the suspended cable reel cannot be coaxial with the support shaft. Off-axis rotation, so it is very easy to cause the support shaft or the cable reel to shake or jump, which will inevitably affect the stability of the cable pay-off

[0006] 4. There is no structure capable of braking the rotation of the cable reel on the pull wire support frame, so that under the action of external force, the cable reel is likely to release too many cables, which will consume extra manpower and time to process it ( winding back or discarding), it is bound to affect the efficiency of cable payout

[0007] 5. Since the cables are mostly stored and transported in the form of coils, the cables will be bent when unwinding, which will greatly affect the efficiency and quality of the subsequent processing of the cables by the operator.
