Pay-off reel with tension automatic adjusting function

Abstract

The invention relates to the technical field of cable processing, in particular to a pay-off reel with a tension automatic adjusting function. The pay-off reel comprises a pay-off reel seat and a pay-off reel seat bearing; a friction disc is connected to the pay-off reel seat bearing; a plurality of symmetrical and horizontally-stored square pipes are connected into the friction disc in a sleevedmode; a tension automatic adjusting device is arranged between the friction disc and the pay-off reel seat and comprises a vertically-arranged tension adjustment screw rod; a vertically-arranged friction block is arranged outside the tension adjustment screw rod; the top end of the friction block makes contact with the friction disc; the bottom of the friction block is provided with a spring stopping block; the lower portion of the spring stopping block is connected with a spring; and the bottom end of the spring is connected with a reducer, and the reducer is connected with a motor. Aluminumrods are placed on the square pipes, in the pay-off process, the aluminum rods rotate, the square pipes can also rotate simultaneously through driving of the pay-off reel seat bearing, thus rotating force of the aluminum rods is offset, and the situation that the aluminum rods are subjected to too large rotation torque, and consequently normal paying off is affected is avoided.

Description

Technical field [0001] The invention relates to the technical field of cable processing, in particular to an automatic tension pay-off reel capable of realizing an automatic adjustment function. Background technique [0002] The cable pay-off rack is a necessary tool for the power pay-off construction project. The pay-off rack has gradually developed from the earliest simple mechanical manual upgrade to the hydraulic jack upgrade, which greatly improves the work efficiency. There are many types of pay-off racks and are available on the market. The upper pay-off reel does not have the function of adjusting tension. When the aluminum rod is paying off on the pay-off reel, it is often difficult to pay off due to the inability to adjust the tension, and it is seriously necessary to stop the machine and reset it. [0003] Existing patent applications such as the patent application number CN 201310359650.0, the application date of 2013-08-16, the invention patent titled "Cradle pay-off r...

Problems solved by technology

[0004] Although the above-mentioned patent improves the structure of the pay-off reel and sets it as a cradle-type pay-off reel, there is still the problem that the tension cannot be adjusted during the pay-off process.
