Description
Technical Field
the utility model relates to a lifting foot hand rack field especially relates to an attached lifting foot hand rack electrical control device.
background
The scaffold for high-rise buildings mainly comprises a lifting scaffold and a fixed scaffold. The lifting scaffold is characterized in that lifting points or descending points of lifting equipment such as N electric hoists act on a frame body when the lifting scaffold is lifted or descended, the frame body is lifted or descended together, however, in the lifting or descending process of the frame body, due to the fact that the performance difference of the lifting equipment can cause the mutual asynchronism, individual points are lifted or descended too fast, and finally, the local load exceeds the mechanical property of materials to cause safety accidents. According to the existing lifting scaffold control system, each machine position before use, namely each electric hoist needs to pre-tighten a rope for driving a scaffold to lift, after a sub-control pre-tightening button is started, an operator observes and debugs the display of the tension tonnage of the steel wire rope, when the tonnage display reaches a certain value, the sub-control is started and stopped to complete the pre-tightening setting of one machine position, and after all the machine positions are completely set, an integral ascending or descending button can be started to complete the ascending and descending operation of the scaffold. Operating personnel can consume a large amount of man-hours because of the repeated operation pretension procedure at whole operation procedure process to every machine position also needs independent cable junction, makes the electric line arrangement confusion of support body platform, causes the cable to expose in the middle of the work progress easily, brings the hidden danger for the construction safety.
in addition, when a certain machine position is controlled to ascend and descend, other machine positions must be adjusted to the stopping positions, otherwise, other machine positions can all act after the machine position is electrified, and safety accidents are easily caused. In addition, before the scaffold is lifted, all the branch control switches are required to be uniformly adjusted to the 'cis' position, namely the rotation directions are consistent, if one branch control switch is not pressed to the 'cis' position, immeasurable serious results can be caused, and accidents are caused.
