Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, and more particularly to a novel climbing frame intelligent synchronous control system group-controlled multi-machine position staggered starting device. Background Art

[0002] The three-phase motors used in traditional movable scaffolding (climbing frames) are widely used in climbing frame hoisting systems in the construction industry. These systems consist of multiple hoisting motors arranged in a circle around the building. As the construction progresses, the climbing frame is hoisted as a whole. When multiple motors are hoisted synchronously and in a group, dozens of motors are started simultaneously. Because the starting current of a three-phase motor is approximately five times the operating current, the entire starting load is very high, impacting the power grid and lowering the supply voltage. If the main power line is relatively thin, it cannot meet the simultaneous starting current of all motors. The voltage is significantly lowered, preventing the climbing frame motor from starting. This can lead to stalling due to undervoltage, potentially burning out the motor. With the rapid development of the construction industry, the demand for safe, efficient, and intelligent climbing frame construction is becoming increasingly urgent.

[0003] Therefore, how to provide a new type of climbing frame intelligent synchronous control system group control multi-machine staggered starting device that is easy to use, time-saving and safe is a problem that technical personnel in this field urgently need to solve. Utility Model Content

[0007] Preferably, the counter realizes the counting time by setting the oscillation frequency of the counting chip. After the control box is powered on, the number in the counting chip starts counting from zero to full. After the number is full, the output port of the counting box is powered on to start the motor, thereby realizing staggered starting of all motors.

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to the attached Figures 1-3 , which is a multi-position staggered start device for a group control of a new type of intelligent synchronous control system for climbing frames disclosed in the present utility model.

[0019] In this embodiment, it includes a control box 1, a counting box 2 and a motor 3. The control box 1 is connected to the input end of the counting box 2 through a wire, and the motor 3 is connected to the output end of the counting box 2 through a wire, so that the control box 1 controls the start and stop of the motor 3. The counting box 2 includes an upper shell 204 and a lower shell 201. A counter 202 is installed above the bottom plate of the lower shell 201. A counting chip 203 is provided inside the counter 202. By setting the oscillation frequency of the counting chip 203, it starts from zero and counts up to full, just completing a cycle in 1.5 seconds.

[0020] The counting chip 203 uses the model CD4060, that is, the counter 202 is a CD4060 counter. The counting chip 203 fixes the count value uniformly through an AND gate circuit: when the CD4060 counter counts to 4096, the output end of the AND gate outputs a high level, and other count values do not respond, and the output of the AND gate is a low level. When each position receives the group control lifting command, it uniformly detects whether the level output by the AND gate is high. If the output level is high, it means that the CD4060 counter has counted up to 4096, and then the motor 3 can start. Although the circuits and components of each position are exactly the same, just like there are no two completely identical things in the world: similar to two watches, there will be a difference in speed between them. Similarly, it is equivalent to equipping each motor 3 of the climbing frame with a watch (CD4060 counter). After they are powered on, there will sometimes be errors. The oscillator frequencies of the CD4060 counters of each position are more or less different, which also leads to a cumulative time difference when each position reaches the count value of 4096. This error in the count value is the principle of realizing staggered start. However, since the CD4060 counter is a cyclic counter, so, within 1.5 seconds, each climbing frame position will have a count value of 4096, thus realizing the staggered start of multiple positions. By appropriately adjusting the oscillator frequency of the CD4060 counter, in practical applications, for the group control lifting process of multiple positions, taking fifty motors as an example, it can be controlled to complete the staggered start within 1.5 seconds. In this way, during group control, the staggered start process of multiple positions has little impact on the power grid, starts smoothly and orderly, and there will be no situation of locked rotor and motor burnout.

[0021] Above the motor 3 is provided with a junction box 301, which is fixedly connected to the motor 3. The junction box 301 is used to protect the circuit, prevent water and dust, etc. A hook ring 302 is welded and installed on the motor 3, symmetrically and flush-mounted. The motor 3 is carried by a lifting device. Four protruding buckles are provided on the upper shell 204 of the counting box 2, and four notches are provided on the lower shell 201. The protruding buckles on the upper shell 204 are matched with the notches on the lower shell 201, and are detachably and hermetically installed, having the functions of preventing water and dust, etc.
