Automatic coiling and uncoiling device of wound-rotor type

Technical Field

The invention belongs to the technical field of cable winding and unwinding in the communication industry, and particularly relates to a winding type automatic winding and unwinding device.

Background

With the development of communication services, the coverage range of communication signals is wider and wider, however, at present, some places still have no communication signals or the communication signals are very weak, and the mobile communication vehicle can better solve the coverage problem of the communication signals at the places. The mobile communication vehicle is equivalent to a mobile base station, and can fill the places without communication signals or weak signals with the communication signals, so that normal communication is ensured. Such a mobile base station is generally provided with a signal tower on the top, and the signal tower is used for supporting various signal transmitting devices or various signal receiving devices. In order to reduce the shielding and shielding of the complex ground to the signal, the mobile communication vehicle can lift the signal tower when working, erect the signal tower to a high altitude far away from the ground, and then lower the signal tower to store the signal tower into the vehicle when stopping working.

When the signal tower rises or falls to move, the radio frequency cable and the signal transmitting device for communication, the power cable and the control cable of the signal receiving device need to be synchronously wound and unwound with the rising and falling of the signal tower, and the winding and unwinding device is a device for synchronously winding and unwinding the radio frequency cable, the power cable, the control cable and other cables when the signal tower rises and falls. In order to improve the cost performance of the mobile communication vehicle, various signal transmitting devices and signal receiving devices are arranged on the signal tower as many as possible, and the more the devices are arranged, the more the number of cables such as radio frequency cables, power supply cables and control cables is. The existing take-up and pay-off device on the mobile communication vehicle has two types:

the first is a take-up and pay-off device as shown in fig. 1, wherein a cable drum 1-1 rotates around a drum shaft 1-2, releases a cable when rotating counterclockwise, and receives the cable when rotating clockwise; the aerial sockets are arranged on the cable drum 1-1, generally, the number of cables corresponds to the number of the aerial sockets one by one, and the number of cables corresponds to the number of the aerial sockets; one end of a cable 1-3 wound on the cable drum is connected with the aviation socket on the cable drum 1-1, and the other end of the cable is connected to the signal tower. An aerial plug of a terminal cable is connected with a corresponding aerial socket on the cable drum 1-1, a transmission channel between the terminal equipment and the signal tower upper equipment is communicated, and the signal tower upper equipment works; the aviation plug of the terminal cable is disconnected with the corresponding aviation socket on the cable drum 1-1, a transmission channel between the terminal equipment and the signal tower upper equipment is cut off, and the signal tower upper equipment cannot work; when the signal tower is lifted and descended, the cable drum 1-1 needs to synchronously rotate to take up and pay off the cable 1-3, if the aerial plug of the terminal cable and the aerial socket on the cable drum 1-1 are in a connection state when the cable drum 1-1 rotates, a plurality of terminal cables can be twisted together, and the aerial socket and the cable can be damaged, so that when the signal tower is lifted and the cable drum synchronously rotates to take up and pay off the cable, the aerial plug of the terminal cable and the aerial socket on the cable drum 1-1 are in a disconnection state, and the terminal cable is fixed on the adapter 1-5 which does not rotate along with the cable drum 1-1. It follows that this solution has the following drawbacks: firstly, in order to avoid damage to aerial plug and cables, when the cable drum 1-1 rotates synchronously to take up and pay off wires, an aerial plug of a terminal cable and an aerial socket on the cable drum 1-1 need to be in a disconnected state, and communication equipment mounted on a signal tower cannot work at the moment; and secondly, when the signal tower needs to be lifted and the cable drum needs to synchronously rotate to take up and pay off the cable, whether the aerial plug of the terminal cable is pulled out of the aerial socket on the cable drum needs to be confirmed firstly, after the signal tower is lifted in place and the cable drum stops rotating, the aerial plug of the terminal cable is inserted into the aerial socket on the cable drum so as to connect a transmission channel between the terminal equipment and the signal tower loading equipment, the operation is complex, and the manual labor intensity is high.

The second type of take-up and pay-off device adopts a coaxial rotary joint to realize the plug-free function of the cable. This solution is too costly, since the coaxial rotary joint is expensive.

The third type is received and releases line device and is adopted the cable along the mode that communication tower elevating gear spiral coiled, and when the communication tower rose, the cable was the helix and expandes the mode, and when the communication tower descended, the cable was helix compression mode. The function that the plug is exempted from to adopt this mode can realize the cable, but cable length is longer relatively, and signal loss is great relatively, is applicable to the communication equipment that communication tower lift stroke is shorter relatively.

Therefore, at present, no take-up and pay-off device can adapt to automatic take-up and pay-off of various cables, is free from plugging and unplugging, saves labor and reduces communication loss.
