[0024] Working principle: When using the special site hoisting device for the boiler construction site, the staff first turns on the cylinder 22. The rise of the cylinder 22 causes the chain 23 to drive the hanger 26 to move downward through the rotation of the sprocket 1 24 and the sprocket 25. When it moves downward to the required height according to the height of the boiler, the staff twists the handle 32. The handle 32 drives the threaded sleeve 1 33 and the threaded sleeve 2 34 to move inward synchronously through the setting of two sets of reverse threads. The threaded sleeve 1 33 and the threaded sleeve 2 34 simultaneously drive the two sets of connecting rods 1 27 and connecting rods 28 to rotate on the hanger 26. At the same time, when the distance between the connecting rod 1 27 and the connecting rod 28 is reduced, the threaded sleeve 1 33 and the threaded sleeve 2 34 move inward according to the angle between the connecting rod 1 27 and the connecting rod 28.

After the fixation is completed, the staff reversely opens the cylinder 22, and the cylinder 22 drives the chain 23 to move through the rotation of the sprocket 1 24 and the sprocket 2 25. The chain 23 drives the boiler on the hanger 26 to rise, thereby completing the hoisting of the boiler. When it is necessary to move the boiler left and right, the staff turns on the motor 2 19. The motor 2 19 drives the threaded screw 1 20 to rotate on the bracket 2 17, and the threaded screw 1 20 drives the fixing plate 21 to move left and right through the threaded connection. The fixing plate 21 The boiler on the hanger 26 is driven to move left and right by the chain 23. When the motor 219 is turned on, the cylinder 22 should be properly turned on to cooperate, so as to ensure that when the hanger 26 moves left and right, the length of the chain 23 will gradually change. The cylinder 22 should be properly turned on according to the moving distance of the fixed plate 21, so as to ensure that the boiler will not move up and down due to the movement of the fixed plate 21, so that the boiler can remain stable while moving left and right. When it is necessary to move the boiler forward and backward, the staff turns on the motor 6, the motor 6 drives the pulley 7 to rotate, the pulley 7 drives the belt 8 to rotate, the belt 8 drives the pulley 29 to rotate, the pulley 29 drives the rotating shaft 10 to rotate on the bracket 5, the rotating shaft 10 drives the gear 2 11 to rotate, and the motor 6 drives the pulley 7 to rotate, the belt 8 drives the pulley 29 to rotate, the pulley 29 drives the rotating shaft 10 to rotate on the bracket 5, and the rotating shaft 10 drives the gear 2 11 to rotate. Machine 1 6 drives pulley 3 12 to rotate, pulley 3 12 drives belt 2 13 to rotate, belt 2 13 drives pulley 4 14 to rotate, pulley 4 14 drives rotating shaft 2 15 to rotate on bracket 1 5, rotating shaft 2 15 drives gear 1 4 to rotate, so that gear 1 4 and gear 2 11 rotate synchronously on rack 3, and the rotation of gear 1 4 and rotating shaft 2 15 on rack 3 drives bracket 1 5 to move on guide rail 1, and bracket 1 5 drives bracket 2 17 through sliding rod 16 to move synchronously on guide rail 2 2 through rotation of wheel 18, thereby completing the forward and backward movement of the boiler, and through the synchronous rotation of gear 1 4, gear 2 11 and two sets of wheels 18, the boiler is more stable when moving forward and backward, thereby completing the safe lifting of the boiler.
