The effects achieved by this embodiment are as follows: compared with the prior art, the device can balance the gravity center of the whole platform when working aloft on the platform by staff, thereby enabling the whole platform to tend to be balanced, avoiding the occurrence of unbalanced platform conditions caused by unstable gravity center of the platform, increasing the safety of the working of the staff, simultaneously, when the gravity of the inside of the platform is unbalanced, the lower end of the gravity of the lower end of the plate below can form an upward support, the air bag below the position can be inflated, the plate is prevented from falling, and the plane when the staff stands tends to be horizontal, thereby increasing the safety and comfort of the standing of the staff.
The working process and principle of the whole content of the embodiment are as follows:
when a worker is ready to perform an overhead operation, the worker firstly opens a door of the overhead operation platform 101 positioned on the overhead operation vehicle, and then stands on the bottom plate 301 with feet;
Because the standing positions are different, the bottom plate 301 receives the weight of a worker and the gravity of equipment placed on the aerial work platform 101, so that the bottom plate 301 cannot be kept in a horizontal state due to the acting force, one end of the bottom plate 301 receives large gravity and begins to be pressed down, at the moment, the bottom plate 301 rotates by taking a hinge point with the limiting piece 302 as a pivot, one end of the bottom plate 301 receives large gravity and presses down, a supporting piece 303 fixedly connected below the end bottom plate 301 also presses down, and inert gas inside the limiting piece 302 begins to be compressed by one end of the supporting piece 303 penetrating through the inside of the limiting piece 302;
At this time, one magnet 304 slidingly connected inside the limiting member 302 moves towards the center of the limiting member 302 under the compression of gas, during which the restoring spring 305 disposed inside the limiting member 302 is stretched, the balancing weight 306 originally disposed at the center of the limiting member 302 moves towards the other magnet 304 inside the limiting member 302 under the repulsive force of the magnet 304, forcing the other magnet 304 to move away from the center of the limiting member 302, and compressing the restoring spring 305 connected with the magnet 304;
The balancing weight 306 originally positioned at the center of the limiting piece 302 gradually deviates from the center of the limiting piece 302 and moves towards one end of the bottom plate 301 with smaller stress so as to separate from the center of the aerial working platform 101, thus balancing the center of gravity of the aerial working platform 101 and avoiding the situation that the aerial working platform 101 is unbalanced in the air due to unbalanced gravity of the aerial working platform 101 connected with the aerial working vehicle through the mechanical arm, thereby causing personnel injury;
as one end of the bottom plate 301 descends under the unbalanced stress state, the tooth block 307 fixedly connected below the end bottom plate 301 moves downwards under the action of the bottom plate 301, the rotating wheel 308 meshed with the tooth block 307 rotates on the top of the limiting piece 302 by taking a connecting point with the limiting piece 302 as a fulcrum under the action of the tooth block 307, so that the ejector rod 309 meshed with the other side of the rotating wheel 308 is pushed upwards, and an upward supporting force is formed below the descending end of the bottom plate 301;
Along with the lowering of one end of the bottom plate 301, the sensor arranged on the aerial work platform 101 sends out a signal, the supporting air bag 403 arranged below the end bottom plate 301 can convey the air in the air storage tank 401 to the inside of the supporting air bag 403 through the air output pipe 402 under the action of the air storage tank 401 receiving the signal, so that the supporting air bag 403 is unfolded, then an upward support is formed on the end bottom plate 301, the inclination of the bottom plate 301 is reduced, and meanwhile, the supporting air bag 403 can buffer the bottom plate 301 for a worker to stand, so that the standing comfort of the worker is improved;
after the preparation of the staff is completed, the operator controlling the aerial working vehicle can lift the aerial working platform 101 to the expected construction position through the hydraulic rod;
as the position of the aerial working platform 101 is raised, the airflow effect of the aerial working platform 101 is gradually increased, the wind load of the aerial working platform 101 is increased due to the increase of the airflow, the aerial working platform 101 generates wind shock vibration, and the continuous vibration can cause fatigue damage of the aerial working platform 101 and also cause larger deformation and vibration of the working platform under the action of the wind load, so that the service life of the aerial working platform 101 is reduced;
At this time, the cambered surfaces formed by the connecting rods 102 and the baffle plates 103 which are connected with each other in pairs can separate the air flow received by the aerial working platform 101, and along with the increase of the air flow, the rectangular block 111 can drive the push rod 105 fixedly connected with the rectangular block to move in the direction away from the aerial working platform 101 under the action of the wind speed sensor, and the position of the connecting rod 102 in the middle of the position fixedly connected with the other end of the push rod 105 can be changed;
along with the movement of the push rod 105, a positioning block 106 fixed outside the push rod 105 moves along with the push rod, a limiting block 107 hinged with the positioning block 106 moves in a through groove formed in a fixing piece 109 under the action of the positioning block 106, a driven block 108 with one end rotatably connected to the inside of the limiting block 107 moves along with the two ends of the fixing piece 109, a fixing rod 104 rotatably connected with the driven block 108 is driven, a baffle 103 fixed by the fixing rod 104 is changed by taking a connecting point of an adjacent connecting rod 102 as a fulcrum under the action of the driven block 108, at the moment, the radian of an arc-shaped baffle 103 and an arc surface of the connecting rod 102 is reduced, and therefore, the cross-sectional area contacted with air flow is also reduced along with the radian;
