Electromagnetic braking tensioning winch

Abstract

The invention discloses an electromagnetic braking tensioning winch comprising an electromagnetic braking motor and a winch, wherein the electromagnetic braking motor comprises a motor and an electromagnetic brake, and the electromagnetic brake is coaxially arranged at the tail of the motor; the winch is connected with a motor shaft by a coupling; the winch comprises a speed reducer, a support seat, a roller support and a rope twisting roller, wherein the speed reducer is arranged on the support seat; the speed reducer is connected with the rope twisting roller; and the roller support is arranged at the other end of the rope twisting roller. The invention has the advantages of no hydraulic pressure, single electric control on tensioning, faster response capability and more accurate, quicker and stable tension control.

Description

Technical field: [0001] The invention relates to a tensioning winch, in particular to an electromagnetic brake tensioning winch. Background technique [0002] The manual tensioning device and the semi-automatic tensioning control device cannot give the continuity and stability of the tension control of the tape machine, and the hammer tensioning is conditionally limited for the tape machine due to its particularity of installation. Therefore, these three This tensioning method is not comparable to the automatic tensioning control device currently commonly used in tape machines. Here, only the automatic tensioning is described. [0003] Whether the tensioning and control system can provide constant tension and quick response according to the operating conditions of the belt has always been one of the key technologies to solve the long-distance transportation of belt conveyors. my country's research on automatic tensioning control of belt conveyors has been lagging behind. In...

AI Technical Summary

Problems solved by technology

[0012] 1. Domestic automatic tension control device (system): the oil cylinder is automatically tensioned, and the automatic tension control range is small, and it is impossible to realize the whole process and continuous tension control

The pressure balance of the hydraulic system has a large range of changes, the automatic tension control is not accurate, and the stability is poor

The whole part is scattered, the control links are many, and the installation is complicated

The tensioning mode is simple, there are only two control modes, manual and automatic, and the automatic winding function cannot be realized

[0013] 2. Foreign automatic tension control device (system): Although it can provide full-range, continuous and relatively stable tension control, but the electric-hydraulic dual control link, the response of winch tension control is slow

Due to the existence of the hydraulic system, disassembly and maintenance are more complicated

There is no tension control ability after power failure. When the tape machine stops abnormally, the balance and release of tension cannot be achieved, which often causes damage to the winch itself or the tape machine system.
