Description

Technical Field

[0001] The utility model relates to the technical field of wire take-up devices, in particular to a wire take-up device with a flexible connection. Background Art

[0002] A wire take-up device for winding electric wires and wire ropes generally drives a motor to rotate a drum to realize winding and releasing of electric wires and wire ropes, wherein the motor and the drum are directly connected. Under this connection mode, if the drum is stuck and stops due to a fault, the motor will also stop, and the motor will be in a blocked state, which is easy to burn out the motor. When the motor stops, the drum also stops, and the rope or line cannot be released. This problem has not been solved, and a wire take-up device with a flexible connection is now provided. Utility Model Content

[0003] The utility model aims to solve the technical problems that the motor and the reel in the existing wire take-up device are directly connected, the reel and the motor are easily stuck in the event of a fault, resulting in an inability to release the rope or line, and the motor is easily burned out. The utility model aims to provide a wire take-up device with a flexible connection, which forms a flexible connection through magnet attraction, and can still release the line normally when the motor stops. By setting an electronic slip ring, the wire can be rotated 360 degrees to avoid the wire from being twisted and broken.

[0004] The utility model is realized by the following technical solutions:

[0005] A flexibly connected wire take-up device comprises a motor and a reel body, wherein the power output shaft of the motor and the reel shaft of the reel body are connected via a magnetically flexible connecting piece, wherein the magnetically flexible connecting piece comprises a first multi-pole magnet and a second multi-pole magnet, wherein the first multi-pole magnet is connected to the power output shaft of the motor, and the second multi-pole magnet is connected to the reel shaft of the reel body.

[0006] The utility model arranges a first multi-pole magnet and a second multi-pole magnet between the motor and the drum body, and forms a flexible connection through magnet attraction, so that the wire can be released normally when the motor stops. The drum is wound with electric wires or steel wires, such as steel wire ropes, and is used on a high-altitude hanging basket hoist, and is collected and released together with the steel wire rope of the hoist.

[0007] When the wire rope needs to be released, if the motor is damaged, the drum can still release the wire because it is in a flexible connection. In addition, since the number of turns of the wire rope on the drum is different and the motor speed remains unchanged, the rope-release speed will be inconsistent due to the constantly changing winding diameter, and the hoist will pull the rope collector. Since the motor and the drum are in a flexible connection with a magnet, the rope can still be released and retracted normally when the motor stops or the speed is inconsistent with the hoist.

[0008] As a further technical solution of the utility model, a connecting piece is sleeved on the power output shaft of the motor, and the first multi-pole magnet is connected to one end of the connecting piece.

[0009] As a further technical solution of the utility model, a connecting hole is opened in the middle of the first multi-pole magnet and the second multi-pole magnet.

[0010] As a further technical solution of the utility model, the reel shaft passes through the reel body and is connected to the middle part of the reel body.

[0011] As a further technical solution of the utility model, both ends of the reel shaft are rotatably connected to the frame.

[0012] As a further technical solution of the utility model, both ends of the reel shaft are rotatably connected to the frame through bearing seats.

[0013] As a further technical solution of the utility model, the bearing seat includes a first bearing seat and a second bearing seat, and the first bearing seat and the second bearing seat are respectively connected to two ends of the reel shaft.

[0014] As a further technical solution of the utility model, the reel body includes a cylinder and an edge baffle, the cylinder is sleeved on the reel shaft, and edge baffles are arranged at both ends of the cylinder.

[0015] As a further technical solution of the utility model, the motor is fixed on the frame.

[0016] As a further technical solution of the utility model, an electronic slip ring is also connected to the reel shaft.

[0017] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0018] 1. The utility model arranges a first multi-pole magnet and a second multi-pole magnet between the motor and the reel body, and forms a flexible connection through magnet attraction, so that the line can still be released normally when the motor stops.

[0019] 2. The utility model can play a connecting role by sleeve-arranging a connecting piece on the power output shaft of the motor, so as to facilitate the connection of the first multi-pole magnet.

[0020] 3. The utility model also connects an electronic slip ring to the reel shaft. When the wires are rotating, the outgoing and incoming wires will be twisted and broken. By setting the electronic slip ring, the wires can be rotated 360 degrees to avoid twisting and breaking. BRIEF DESCRIPTION OF THE DRAWINGS
