Description
Technical Field
The invention relates to a winding and unwinding device, in particular to an automatic winding and unwinding device applied to a communication vehicle, and belongs to the technical field of winding and unwinding of cables in the communication industry.
Technical Field
With the development of communication industry, the coverage range of communication signals is wider and wider, however, at present, some places have no communication signals or the communication signals are weak, so that the mobile communication vehicle can better solve the coverage problem of the communication signals in the places. The mobile communication vehicle is equivalent to a mobile base station, and can fill the places without communication signals or with weak signals with communication signals, thereby ensuring normal communication. Such mobile base stations are typically equipped with a signal tower on top, which functions to support various signal transmitting devices or various signal receiving devices. In order to reduce the shielding and shielding of signals in complex ground, the signal tower is lifted when the mobile communication vehicle works, erected to the high altitude far away from the ground, and then lowered and stored in the vehicle when the mobile communication vehicle stops working.
When the signal tower moves up or down, the radio frequency cable, the signal transmitting device, the power cable and the control cable of the signal receiving device for communication need to do synchronous winding and unwinding movement with the lifting 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 lifts.
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 much as possible, and the more the devices are arranged, the more the number of cables such as radio frequency cables, power cables, control cables and the like are.
The existing coiling and uncoiling devices on mobile communication vehicles have two types:
the first is a winding and unwinding device as shown in fig. 1, wherein a cable drum 1-1 rotates around a drum shaft 1-2, releases a cable when rotating anticlockwise, and accommodates the cable when rotating clockwise; a plurality of navigation sockets are installed on the cable drum 1-1, in general, the number of cables is in one-to-one correspondence with the number of navigation sockets, and the number of navigation sockets corresponds to the number of cables; one end of the cable 1-3 wound on the cable drum is connected with the navigation socket on the cable drum 1-1, and the other end is connected with the signal tower.
The aviation plug of the terminal cable is connected with the corresponding aviation socket on the cable drum 1-1, a transmission channel between terminal equipment and signal tower mounting equipment is communicated, and the signal tower mounting equipment works; the aerial plug of the terminal cable is disconnected with the aerial socket on the corresponding cable reel 1-1, a transmission channel between the terminal equipment and the signal tower mounting equipment is cut off, and the signal tower mounting equipment cannot work; when the signal tower is lifted, 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 is in a connection state with the aerial socket on the cable drum 1-1 when the cable drum 1-1 rotates, a plurality of terminal cables can be screwed together to cause damage to the aerial plug and the cable, so when the signal tower is lifted and the cable drum synchronously rotates to take up and pay-off, 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: (1) in order to avoid damage to the aerial plug and the cable, when the cable drum 1-1 rotates synchronously to take up and pay off, the aerial plug of the terminal cable and the aerial socket on the cable drum 1-1 are required to be in a disconnected state, and the communication equipment on the signal tower cannot work at the moment; (2) when the signal tower needs to be lifted and the cable drum needs to synchronously rotate to take up and pay off, whether the aerial plug of the terminal cable is pulled out of the aerial socket on the cable drum needs to be confirmed, 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 be communicated with a transmission channel between terminal equipment and signal tower mounting equipment, the operation is complex, and the labor intensity is high.
The second type of winding and unwinding device adopts a mode that a cable is spirally wound along a communication tower lifting device, when the communication tower ascends, the cable is in a spiral line unfolding mode, and when the communication tower descends, the cable is in a spiral line compression mode. The mode can realize the function of plugging-free cable, but the cable has relatively longer length and relatively larger signal loss, and is suitable for communication equipment with relatively shorter lifting stroke of the communication tower.
Therefore, at present, no winding and unwinding device is available, which is suitable for automatic winding and unwinding of various types of cables, can avoid plugging and pulling, saves labor and reduces communication loss.

In the ascending or descending process of the communication tower, when the take-up and pay-off device rotates, the combined design of the central cavity 14, the radio frequency rotary joint A6, the radio frequency rotary joint B22, the fixed shaft A3, the fixed shaft B21, the poking piece 11, the bearing seat A10 and the bearing seat B19 is utilized to realize the plug-free function of external input cables and aviation plug, namely, after the external input cables and the aviation plug are in plug-in connection with the aviation socket, the external input cables and the aviation plug are not required to be plugged-out and separated from the aviation socket when the automatic take-up and pay-off device works and does not work.
In summary, the above embodiments are only preferred embodiments of the present invention, and are not intended to limit the scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
