Description

Control system for attached lifting scaffold

Technical Field

The utility model relates to a control system, especially an inserted lift control system for scaffold frame.

Background

The attached lifting scaffold is an outer scaffold which is erected at a certain height, attached to an engineering structure, can ascend or descend layer by layer along with the engineering structure by virtue of self lifting equipment and devices, is provided with an anti-overturning and anti-falling device, and is commonly called a climbing frame; the existing system for controlling the lifting of the climbing frame mainly has the following defects;

1. the climbing frame does not have a warning function in lifting: the climbing frame control system (equipment) commonly used in the market does not have any prompt function in the actual use process, only alarms and prompts when faults occur, however, in a complex construction site, the sound is noisy, a lot of constructors exist, various workers perform cross operation, and when the equipment normally operates, if no alarm sound exists, misoperation, mistaken collision and the like of workers are easily caused, so that the equipment operation faults can be caused, and the personal safety of the workers is endangered.

2. The problem of series connection of the sub-control boxes is as follows: in actual field use, in order to save cost and simplify equipment connection mode, power lines and communication lines between a main control box and N sub-control boxes (N is more than or equal to 30) are connected in series, although the cost is reduced in the connection mode, due to the fact that the number of the sub-control boxes is large, normal operation of each equipment is difficult to guarantee, when one line breaks down, all the sub-control boxes behind the line can lose power and stop, all electric hoists stop along with the sub-control boxes, the load value is uneven, and the difficulty in fault removal is increased.

3. No data storage and wireless transmission function: in an actual construction site, various data are immediate, a data storage function is not available, critical data cannot be checked and traced, and problems cannot be examined due to lack of operation data; the multi-group climbing frame system is simultaneously promoted, the back platform is free of unified data monitoring, managers often can consider the system, the back platform can receive running data through a wireless transmission function, the running data of each climbing frame system is displayed in real time, the problems can be found in time, and unified command and solution are achieved.

4. Climbing frame adheres to support anchor and does not have the monitoring problem: at present, the climbing frame is fixed by concrete columns or beams of a building, the selection of a mounting point depends on a position given by a design institute, and theoretically, the anchoring strength has no problem, but in the actual mounting process, the problem appears endlessly, and all anchoring points have no monitoring equipment, so that the problems are difficult to find only by naked eyes, such as: the mounting bolt is not fastened in place, and the problems of looseness and tripping occur; the punching position on the concrete column is deviated, the bearing capacity is reduced, and concrete cracking can be caused; concrete placement is unreasonable or because of weather problem leads to concrete intensity to be less than design strength etc. far away, and a great deal of reasons all can lead to climbing the whole problem such as toppling, distortion, deformation of frame, and more serious can lead to climbing the frame and drop, causes personnel and equipment loss.

5. The electric hoist lacks the looks problem: the starting and stopping of the electric hoist are realized through the sub-control box in the current climbing frame control system, only the contactor switch control circuit is switched on and off, no protective device is provided, when the motor is in phase failure or under-voltage, the motor current is overlarge, the motor is burnt out, whether the motor normally works is judged by the gravity sensor, the method cannot effectively solve the phase failure problem, and once the signal transmission is too slow, the motor is burnt out.
