The invention aims to overcome the defects of the prior art and provides the driving mechanism for driving the sliding frame on the flying tower to lift, which has the advantages of simple structure, low cost, low power, low running cost, convenience in controlling the lifting speed and contribution to quickly rescuing passengers under the abnormal conditions of power failure and the like in case of accidents.
The purpose of the invention is realized by the following steps:
a novel driving mechanism for driving a sliding frame to lift comprises a tower frame, wherein the tower frame is provided with the sliding frame capable of sliding up and down and rotating on the tower frame, and the novel driving mechanism is characterized in that one side of the tower frame is provided with a hydraulic cylinder for pulling the sliding frame to slide up and down on the tower frame, and the other side of the tower frame is also provided with a balance weight connected with the sliding frame.
The novel driving mechanism for driving the sliding rack to lift is characterized in that a first fixed pulley and a second fixed pulley are arranged at the top end of the tower, the driving mechanism is connected with one side of the sliding rack through a first pull rope, and the first pull rope bypasses the first fixed pulley; the counterweight is connected with the other side of the sliding rack through a second pull rope, and the second pull rope passes around the second fixed pulley.
The novel driving mechanism for driving the sliding frame to ascend and descend is characterized in that the tower frame is further provided with an upper fixed pulley block and a lower movable pulley block, the upper fixed pulley block is provided with a plurality of fixed pulleys, the lower movable pulley block is provided with a plurality of lower movable pulleys, and the first pull rope bypasses the plurality of fixed pulleys and the plurality of lower movable pulleys.
The novel driving mechanism for driving the sliding frame to lift is characterized in that a pair of guide wheels is further arranged on the tower frame and is arranged between the first fixed pulley, the second fixed pulley and the upper fixed pulley block.
The invention has the beneficial effects that:
a hydraulic cylinder for pulling the sliding frame to slide up and down on the tower frame is arranged on one side of the tower frame, and a balance weight connected with the sliding frame is arranged on the other side of the tower frame. The telescopic action of the hydraulic cylinder is adopted to realize the lifting of the sliding frame, and the hydraulic cylinder can slowly extend out of return oil by means of releasing a hydraulic cylinder control valve and the like under abnormal conditions such as power failure and the like, and the sliding frame slowly falls back to a low point, so that passengers can be quickly rescued; the weight of the counterweight offsets the weight of the sliding rack, thereby reducing the driving power of the hydraulic cylinder, and having simple structure and low cost.
