Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, and more specifically, to a one-key phase-changing device for controlling motors in a new type of intelligent synchronous control system for climbing scaffolds. Background Art

[0002] During the lifting control process of traditional movable scaffolds (climbing scaffolds), it is usually necessary to manually pre-tighten the electric hoist chains at each position. This not only consumes a large amount of man-hours but also poses a relatively large safety hazard. The climbing scaffolds currently widely used in the climbing scaffold lifting system in the construction industry consist of many sub-control lifting motors arranged in a circle around the building. As the construction progresses upward during the construction period, the overall lifting of the climbing scaffold is realized. Obviously, this lifting process requires overall synchronous lifting. Otherwise, it will tilt due to asynchronous lifting. Since these motors all use three-phase power motors, as is common knowledge, if any two power supply lines of a three-phase motor are exchanged, the motor will reverse. The entire climbing scaffold is synchronously lifted by dozens of such three-phase motors. When electricians install them, the wire sequences of some motors are often misconnected. That is, when powered on, some motors rotate forward and upward, while the lifting motors with misconnected wires rotate downward. After power-off, electricians need to correct the running directions of all motors one by one. They need to work at heights. First, power off, then use tools to disassemble the wiring box of the sub-control motor controller, exchange the three-phase power supply inlets of the motors, and then power on to verify whether the running directions are the same. Since these climbing scaffold sub-controllers are installed in very high places, it is time-consuming and dangerous for electricians to correct them one by one, and the operation process requires great care. In addition, although some existing intelligent climbing scaffold control systems have improved the automation level, they still need to be improved in terms of motor phase change, fault detection, and emergency handling.

[0003] Therefore, how to provide a one-key phase-changing device for controlling motors in a new type of intelligent synchronous control system for climbing scaffolds that is convenient, fast, time-saving, and safe is an urgent problem to be solved by those skilled in the art.

A one-key phase-changing device for controlling motors in a new type of intelligent synchronous control system for climbing scaffolds includes: a motor and a sub-motor control box.

[0017] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to the Figures 1 - 3 , which is a one-key phase conversion device for a control motor of a new type of intelligent synchronous control system for climbing frames disclosed by the present utility model.

[0019] In this embodiment, it includes a motor 4 and a branch motor control box 5. The branch motor control box 5 includes a reversing switch 1, a branch motor driving contactor 2, and a microprocessor 3. The reversing switch 1 is installed on the panel 501 of the branch motor control box 5, and the branch motor driving contactor 2 and the microprocessor 3 are installed inside the branch motor control box 5. There is a junction box 402 above the motor 4. The branch motor control box 5 and the junction box 402 are connected by wires, so that the branch motor control box 5 and the motor 4 are connected. The junction box 402 also serves to protect the wiring port.

[0020] The microprocessor 3 is connected to the reversing switch 1 and the branch motor driving contactor 2 by wires. The branch motor driving contactor 2 and the motor 4 are connected by wires. The wire of the reversing switch 1 is connected to the signal input port of the microprocessor 3, and the signal output port of the microprocessor 3 is connected to the branch motor driving contactor 2. The branch motor driving contactor 2 has two types: a forward rotation contactor 201 and a reverse rotation contactor 202. The forward rotation contactor 201 and the reverse rotation contactor 202 are respectively connected to two signal output ports of the microprocessor 3.

[0021] The signal output port of the branch motor driving contactor 2 is connected to the motor 4. The microprocessor 3 collects, detects, and processes the signal of the level high and low input by the reversing switch 1, makes a reaction, and then transmits the signal to the branch motor driving contactor 2, so as to realize the forward and reverse rotation of the motor 4.

[0022] The forward rotation contactor 201 controls the forward rotation of the motor 4, and the reverse rotation contactor 202 controls the reverse rotation of the motor 4. After the extension motor control box 5 is powered on, if the signal input port of the microprocessor 3 detects that the reversing switch 1 is in the off state, then after power-on, the microprocessor 3 starts the forward rotation contactor 201 through the signal output port, and then after the climbing frame is powered on, the motor 4 rotates forward; if the signal input port of the microprocessor 3 detects that the reversing switch 1 is in the closed state, then after power-on, the microprocessor 3 starts the reverse rotation contactor 202 through the signal output port, and then after the climbing frame is powered on, the motor 4 rotates in reverse. In this way, only by pressing an operation of the reversing switch 1, the reversing operation of the climbing frame motor 4 can be simply and conveniently realized.

[0023] A lifting ring 401 is provided above the motor 4, and the motor 4 is carried by a lifting and handling device.

[0024] To further optimize the above technical solution, the reversing switch 1 is selected as a waterproof sealed switch, model SJ3-2PSAJOO, a ship-shaped waterproof switch; the microprocessor 3 is selected as a PIC16F73 eight-bit high-performance reduced instruction processor; the climbing frame extension motor drive contactor 2 is selected as a CJX2-0901Z small contactor with a 12V coil voltage.
