[0020] The upper and lower parts of the two Bailey beam combination trusses 2 are hinged to the bottom sliding beam 1 and the longitudinal beam 3 respectively, with one side being fixed and the other side being sliding.

[0021] like Figure 4 、 5 As shown, the hydraulic jacking unit 6 includes a left jacking frame 61, a right jacking frame 62, a shoulder beam 63, and a jacking cylinder 64. The left jacking frame 61 and the right jacking frame 62 are respectively arranged on both sides of the Bailey beam combination truss 2. The tops of the left jacking frame 61 and the right jacking frame 62 are respectively connected to the fixed ends of the jacking cylinder 64, and the output ends of the two jacking cylinders 64 are connected to the two ends of the shoulder beam 63.

[0022] The shoulder beam 63 passes through the bottom of the middle hinge 21 of the Bailey beam composite truss 2 and is hinged to the middle hinge 21 .

[0023] The Bailey beam composite truss 2 is composed of a combination of Bailey frames.

[0024] The longitudinal beam 3 includes an upper slide 31, a lower slide 32, and a Bailey beam 33. The upper slide 31 and the lower slide 32 are respectively arranged on the upper and lower sides of the Bailey beam 33. The upper slide 31 is used to carry and support the crossbeam 4 to achieve longitudinal movement of the crossbeam 4 along the slide direction; the lower slide 32 is used to achieve sliding of the upper moving end when the device is lifted.

[0025] The crossbeam 4 is a triangular truss structure, with four longitudinal moving trolleys 41 at the bottom connected to the upper slide 31, and a transverse track at the top for sliding connection with the lifting trolley 5; the longitudinal moving speed is 0-3m / min, and the crossbeam 4 weighs about 30 tons.

[0026] The rated lifting capacity of the lifting trolley 5 is 100 tons. It consists of a winch, a movable and fixed pulley set, a trolley frame, a transverse movement mechanism, a wire rope, a sling, etc. The transverse movement mechanism is equipped with a three-in-one motor reducer. The lifting and traveling of the lifting trolley are both frequency controlled; the lifting speed of the lifting trolley is 0-1m / min, and the transverse movement speed is 0-3m / min; it is equipped with safety devices such as a load limiter, a height limiter, and an overspeed switch, and the protection level of the traveling motor is IP55; a rainproof room is provided to ensure that rainwater does not enter the trolley; the rainproof room has a certain height to ensure that personnel can perform maintenance operations inside, and there are lighting facilities in the rainproof room.

When it needs to be lifted, the piston rods of all the lifting cylinders 64 are retracted through hydraulic drive, and the Bailey beam combination truss 2 is driven to rise and unfold through the shoulder beam 63 until the required position is met. The hydraulic drive stops working, and then all the lifting cylinders 64 are paused; at this time, the longitudinal position is adjusted on the longitudinal track on the upper slide 31 through the crossbeam 4, and then the lifting trolley 5 is adjusted in the transverse position through the transverse track on the crossbeam 4. After reaching the appropriate position, the lifting trolley 5 performs the lifting work.

[0029] After the lifting work of the lifting trolley 5 is completed, the piston rods of all the lifting cylinders 64 are extended through hydraulic drive, and the Bailey beam composite truss 2 is gradually lowered to the initial position, and then the hydraulic drive stops working.
