The control box in the embodiment is fixed, and the control box can be changed into a handheld type according to needs.
The control principle is as follows:
when in a lifting mode, a key is started to lift the locking button, and the servo control box 2 realizes the control of starting, accelerating, uniform speed, decelerating and stopping of the motor by acquiring in-place sensor signals at different positions. Two in-place sensors 23 are respectively arranged at the upper position and the lower position, and are sequentially marked as 23-a, 23-b, 23-c and 23-d from top to bottom, the control box detects that the induction point 24 is between the in-place sensors 23-c and 23-d, the motor is controlled to accelerate, and the lifting rod 1 is accelerated to lift; after the servo control box 2 detects that the induction point 24 is positioned at the in-place sensor 23-c, the motor 5 is controlled to rotate at a constant speed, and the lifting rod 1 rises at a constant speed; after the servo control box 2 detects that the induction point 24 is positioned at the in-place sensor 23-b, the motor 5 is controlled to decelerate, and the lifting rod A decelerates; after the servo control box B detects that the induction point a is located at the in-place sensor 23-a, the control motor 5 stops, the lifting cylinder mounting seat 11 is limited by the guide sleeve 13 at the moment, the bolt 30 faces the locking hole in the lifting cylinder mounting seat 11, and the servo control box 2 controls the electric push rod 26 to insert the bolt 30 into the locking hole, so that the locking of the lifting rod 1 is realized. Generally, due to processing and assembly errors of equipment, when a servo control box 2 detects that an induction point 24 is located at an in-place sensor 23-a, a lifting cylinder mounting seat 11 and a guide sleeve 13 are not completely limited, the servo control box 2 can control a motor 5 to slowly move, a lifting rod 1 continues to ascend, when the lifting cylinder mounting seat 11 and the guide sleeve 13 are completely limited, a control current of the motor 5 is increased, a torque limiter 7 limits further increase of the control current by slipping, the servo control box 2 controls an electric push rod 26 to insert a plug pin 30 into a locking hole, the servo control box 2 judges whether a locking mechanism is locked in place or not by collecting a locking in-place signal on the electric push rod 26, and controls the electric push rod 26 to stop after the locking in place; finally, the servo control box 2 controls the motor 5 to stop. The relative position relation between the bolt 30 and the locking hole is ensured by mechanical limit of the lifting rod 1, and the control precision requirement of the device on a control system is not high; after the lifting rod 1 is limited, the system can be protected by slipping of the torque limiter 7, the servo controller is designed for overload protection of the motor, the overload current is greater than the current required by slipping of the torque limiter 7, and the mechanical and electrical dual protection of the device is realized;
in the descending mode, a one-key unlocking descending button is started, after the servo control box controls the locking mechanism to be unlocked, the starting motor 5 is started and operates in an accelerating mode, and the lifting rod 1 begins to descend; after the servo control box 2 detects that the induction point 24 is positioned at the in-place sensor 23-a, the motor 5 is controlled to rotate at a constant speed, and the lifting rod 1 descends at a constant speed; after the servo control box 2 detects that the induction point 24 is positioned at the in-place sensor 23-c, the motor 5 is controlled to decelerate, and the lifting rod 1 decelerates and descends; after the servo control box 2 detects that the induction point 24 is located at the in-place sensor 23-a, the motor 5 is controlled to stop, at the moment, the antenna mounting base 12 and the limiting sleeve 22 are mechanically limited, the lifting rod 1 stops moving, and the closing of the lifting rod is realized. Generally, the height of the lifting rod 1 is slightly reduced due to unstable load borne by an antenna, a gap between the plug pin 30 and a locking hole is eliminated, when the locking mechanism is unlocked, the friction force is increased, and when the locking mechanism is seriously unlocked, the locking mechanism cannot be unlocked, in control, after a one-key unlocking and descending button is started, the motor 5 slowly rotates to control the lifting rod 1 to ascend to a mechanical limit position, the servo control box 2 controls the locking mechanism to unlock and controls the motor to stop, and after the locking mechanism is unlocked, the servo control box 2 controls the motor 5 to reversely start and accelerate, and the lifting rod 1 starts to descend; due to the existence of processing and assembling errors, when the servo control box 2 detects that the induction point 24 is located at the in-place sensor 23-a, the lifting rod 1 is not completely mechanically limited, the motor 5 continues to move slowly, when the lifting rod 1 is completely mechanically limited, the moment limiter 7 protects the lifting rod 1 through slipping, and then the servo control box 2 controls the motor 5 to stop, so that the lifting rod 1 is closed.
