Cable reels are widely used in many mobile equipment such as ports, terminals, water conservancy projects and steel, such as gantry cranes, tower cranes, portal cranes, shore bridge container cranes, bulk material handling machinery (bucket wheel stacks). Reclaimer) Hydropower station dam door machine and electric flat car, stage lighting and so on. With the development of the economy, cable reels are also becoming more and more perfect.
It is a mechanical device that automatically winds up the cable using the principle that the weight is raised and stored. When the cable is pulled out, the cable reel is rotated, and then the wire rope reel which is coaxially connected with the cable reel is driven to increase the weight and store potential energy. When the reel is coiled, the weight of the hammer is lowered to release the potential energy. Under the effect of the tension of the wire rope, the cable reel which is coaxially connected with the wire reel is driven to roll, and the cable is synchronously wound.
The permanent magnet coupler is used for synchronous differential organization. The cable-receiving process is to drive the reel winding cable through the permanent magnet coupler, and the differential slip between the coupler and the reel is performed to ensure that the cable speed is the same as the moving speed of the device, and the output torque of the permanent magnet coupler is adjusted. The tension of the cable can be adjusted within a certain range. The cable-drawing process is through a one-way gathering device, and the power cannot be transmitted to the coupler and the reel. Under the cable pulling effect, the reel overcomes the stagnation effect of the cable hysteresis, and the cable is synchronously placed. The cable reel can be divided into two types: powered and unpowered according to the power system.
