Hereinafter, an operation process of an embodiment of the present invention will be described.

In the state in which the movable body 200 is coupled to the fixed body 100, the locking blades 701, the locking portions 719, and 721 of the 703 pass through the opening of the side plate of the insertion assembly 600 to move the movable body 200. Since the state is inserted into the opening of the opening), the moving body 200 is maintained in a locked state that cannot move downward. In this state, the plugs 105 and 107 are inserted into the receptacles 209 and 211, respectively, so that the plugs 300 and 107 are electrically connected to each other. .

In such a state, when the administrator wants to move the camera 300 downward for the maintenance of the camera 300, the lock release signal for separating the moving object 200 from the fixed body 100 is supplied to the controller by a wireless remote controller. In this case, the controller supplies a separate control signal to the driving circuit for operating the solenoid 707 so that the solenoid 707 reverses the operating rod 713, and the locking parts 719 and 721 move outward. By turning, the locking state is released by being separated from the side plate opening of the movable body 200, and the downward preparation of the movable body 200 is performed.

While the manager continuously supplies the downlink signal to the controller 740 with the wireless remote controller, the controller 740 moves the motor 141 in the direction in which the wires 400 wound around the winding rollers 101 and 103 are released. When the wire 400 is released from the winding rollers 101 and 103, the movable body 200 is moved downward.

It rotates in the direction to move the movable body 200 up.

At this time, since the movable body 200 is moved upward by the two winding rollers 101 and 103, the moving body 200 is movable upward by the rotational force of 1/2 when it is moved upward by one conventional winding roller. ) Is capable of upward movement even if a small rotational torque is generated, and since the two winding rollers 101 and 103 having one rotation shaft 135 are simultaneously rotated by one motor 141, the movable body 200 is rotated at the same time. The phenomenon of tilting is prevented. In addition, two winding rollers 101 and 103 are spaced apart from each other, and the guide rods 201 and 203 can be spaced apart from each other to prevent twisting of the wire 400. Since the wire 400 passes through the wire through holes 113 and 115 of the fixed body 100 having a small diameter and the wire through holes 241 and 243 of the movable body 200, the flow becomes small.

The wire through holes 113, 115, 241, and 243 are larger than the diameter r1 of the wire 400 so that the wire 400 passes without friction, but the wire through holes 113, 115, The size of the wire 400 does not flow in 241 and 243, and the maximum size should be smaller than the diameter r2 of the guide rod insertion holes 109 and 111. When the wire 400 is wound on the winding rollers 101 and 103 in this way, the movable body 200 is moved upward so that the movable body 200 is inserted into the insertion assembly 600. Is coupled to the receptacles 209 and 211, and when the administrator supplies the locking signal to the controller 740 with the wireless remote controller, the controller 740 advances the actuation rod 713 to the solenoid 707. When the control rod 713 is advanced, the locking portions 719 and 721 are inserted into the openings of the side plates of the movable body 200 and are eventually locked.

In the present invention, when a downward signal is supplied instead of supplying a unlocking signal, a lock release is generated, and instead of supplying a locking signal, a sensor detects this and is automatically locked when the moving object 200 is inserted into the insertion assembly. Can be.

In addition, in the present invention, an opening is formed in the lower plate in the housing, and the insert assembly is installed in the upper portion of the opening as an example, but the insertion assembly may be integrally configured as one housing.

As described above, the present invention can be foreseen by those skilled in the art that various devices can be designed based on the embodiments. The protection scope of the present invention should be defined by the claims.
