The motor is hidden inside the connecting piece 401, and is electrically connected with the connecting switch 410, and the connecting cylinder 407 is in a slightly downward inclined state.
The steel structure hoisting construction method for road and bridge and building construction comprises the following steps:
s1: firstly, a worker needs to enter the crane 1 and drive the crane 1 to a proper position, then the telescopic lifting column 3 is started to lift the steel structure, at the moment, the telescopic lifting column 3 synchronously drives the connecting piece 401 to shift downwards, the hook 405 synchronously moves, and when the hook 405 is connected with the steel structure, the worker upwards adjusts the telescopic lifting column 3, and the steel structure finishes the lifting work;
s2: the steel structure can bear force on the hook 405 in the process of being connected by the hook 405 and being driven upwards, if the hook 405 bears force for a long time, the inside of the rope 403 can be aged, and the maintenance needs to be carried out manually and regularly;
s3: if the investigation is not complete due to negligence during manual overhaul, the rope 403 may break suddenly, the rope 403 will not press the alarm 408 any more, the alarm 408 will drive the connecting rod 409 to slide downwards at this time, and the alarm 408 will start to sound and alarm, so as to remind the field staff that the rope 403 breaks, and the situation is dangerous.
When the steel structure lifting device is used, when a worker needs to lift a steel structure, the worker firstly needs to enter the crane 1 and drive the crane 1 to a proper position, then the worker starts the telescopic lifting column 3 in the crane 1, the telescopic lifting column 3 needs to be adjusted to a proper height after being started, at the moment, the telescopic lifting column 3 can drive the connecting piece 401 to move, meanwhile, the hooks 405 can synchronously move, when the hooks 405 are adjusted to a proper position, the worker can extend the hooks 405 into the traction piece outside the steel structure, then the telescopic lifting column 3 is controlled to be lifted upwards, the connecting piece 401 can synchronously lift, and the hooks 405 can drive the steel structure to gradually reach the needed height or position;
in the working process, since the bottom of the steel structure is separated from the ground in an inclined state when the steel structure is hooked by the hook 405, the steel structure swings to a certain extent when being suspended, the steel structure is impacted towards the sealing frame 406, when the steel structure is contacted with the stress plate 504, the stress plate 504 is extruded, the stress plate 504 synchronously drives the supporting plate 503 to move in the moving process, the supporting plate 503 can extrude the sealing piston plate 502 in the moving process, and the sealing piston plate 502 synchronously extrudes the spring 501, so that the effect of buffering the steel structure when being suspended is achieved, and the condition that the inside of the rope 403 is continuously stretched and aged due to the fact that the weight of the steel structure is large in the shaking process is prevented;
in the working process, the sealing piston plate 502 synchronously extrudes the gas in the sealing frame 406 after being extruded, so that the gas enters the connecting pipe 505, the sealing column 506 moves outwards under the force of the gas pushing, meanwhile, the friction plate 507 also moves, the friction plate 507 can limit a suspended swinging steel structure after moving, the condition that the crane 1 controls the base 2 to swing again in the steering process is prevented, and the service life of the rope 403 is ensured;
if the dead weight of the steel structure is heavy and the steel structure falls down when the steel structure is aged to cause sudden fracture, the steel structure can drive the hook 405 and the fixed block 404 to fall down when falling, the rope 403 breaks down already at the moment, so the rope 403 can be separated from the alarm 408, the alarm 408 can start to extend to the outside of the connecting cylinder 407 when not receiving the pressure of the rope 403, and meanwhile the alarm 408 can alarm to sound to remind surrounding staff that the rope 403 breaks suddenly and needs to leave the site, so that unnecessary casualties are prevented;
in the above working process, since the alarm 408 drives the connecting rod 409 to move in the process of moving outwards, when the connecting rod 409 contacts with the connecting switch 410, the connecting switch 410 is forced to be opened, the connecting switch 410 can control the motor inside the connecting piece 401 to no longer work at this time, so as to prevent the condition that the motor continues to work after the rope 403 breaks;
in the working process, the friction plate 507 still applies force after the rope 403 is broken, so that the friction plate 507 can be used for increasing friction when the friction plate 507 clamps the steel structure, the falling speed of the steel structure is slowed down to a certain extent, the steel structure is prevented from falling too fast, and the safety of the site is further ensured.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
