Description
Technical Field
The utility model belongs to the nuclear power station technique, concretely relates to lifting device.
Background
The hoisting equipment crane of the conventional nuclear power unit adopts a hoisting mode of hoisting and binding a track and then hoisting the track by using a chain block, but because the chain block body has a certain height, even if the track is hoisted to a position between an upper limit position and an adjusting base plate, a certain distance is still left, at the moment, the track is hoisted to be in contact with the adjusting base plate by manpower or other methods, and then the adjusting base plate is kept in the state and is connected with the track by spot welding by a welder, the method is time-consuming and labor-consuming, the method can be adopted under the condition of small number of cranes, but the hoisting equipment crane in the Hualongyi nuclear power station has huge number of hoisting equipment cranes and more long tracks, most of tracks are directly welded on the adjusting base plate (the adjusting base plate is welded on an embedded plate in a room), and the hoisting mode of hoisting and binding the track by using the chain block after binding, the working efficiency is very low.
Disclosure of Invention
The utility model aims at providing a nuclear power station handling equipment mounting rail lifting device, it can directly promote the track to hugging closely the adjustment backing plate, and does not need the manpower to come the jacking track.
The technical scheme of the utility model as follows:
the utility model provides a nuclear power station handling equipment mounting rail lifting device, includes the I-steel C of bottom, is located the I-steel B of I-steel C top, and is located the I-steel A of I-steel B top, I-steel A on be equipped with the clamp plate connecting piece.
The pressing plate connecting piece comprises a pressing plate and a pressing bolt, and the pressing bolt connects the pressing plate with the I-shaped steel A through threads.
The installation direction of the I-shaped steel A is perpendicular to that of the I-shaped steel B.
The I-steel B is shorter than the I-steel C, and lifting lugs are fixedly arranged at the two ends of the upper surface of the I-steel C.
The lifting lug is welded with the I-shaped steel C.
The lifting lug is connected with the lifting hook.
And the I-shaped steel B is connected with the I-shaped steel A through bolts.
And the I-shaped steel C is fixed with the I-shaped steel B through welding.
The utility model discloses a show the effect as follows: the hoisting tool adopts 3I-steel welding or bolted connection to form a main body structure, lifting lugs are welded on two sides of the bottom I-steel respectively and used for being connected with a chain block, the hoisting tool can directly lift the rail to be close to the adjusting base plate, manpower is not needed for jacking the rail, and construction is facilitated. Compared with the original hoisting mode that the tracks are jacked to be tightly attached to the adjusting base plate by manpower, the new tool can save the manpower of the part, and 2 daily workers are saved for each track. 860 rails need to be installed in an EM10 (electromechanical installation package, namely hoisting equipment installation with the load less than 40 tons) working package of the Hualong I nuclear power station, and 1720 daily workers can be saved.
Drawings
FIG. 1 is a schematic view of a lifting tool for a mounting rail of lifting equipment of a nuclear power plant;
FIG. 2 is a front view of a lifting tool for a mounting rail of lifting equipment of a nuclear power plant;
in the figure: 1. i-shaped steel A; 2. a bolt; 3. lifting lugs; 4. a platen connector; 5. h-shaped steel B; 6. and H-shaped steel C.
Detailed Description
The present invention will be further explained with reference to the drawings and the detailed description.
As shown in fig. 1, the i-steel C6 is positioned at the bottom, the i-steel B5 is fixedly welded above the i-steel C6, the length of the i-steel B is shorter than that of the i-steel C6, and the lifting lugs 3 are fixedly mounted at two ends of the upper surface of the i-steel C6.
And I-steel A1 is arranged above the I-steel B5, the installation direction of the I-steel A1 is perpendicular to the I-steel B5, and the I-steel A1 is fixed by bolts 2.
And a pressure plate connecting piece 4 is arranged on the I-shaped steel A1. The pressing plate connecting piece 4 comprises a pressing plate and a pressing bolt, the pressing bolt connects the pressing plate with the I-shaped steel A1 through threads, and the hoisting track is pressed through the pressing plate through adjusting the threads.
The size of the I-steel A1 is 200X 300mm, the size of the I-steel B5 is 140X 210mm, and the size of the I-steel C6 is 150X 380 mm.
The I-shaped steel A1 is mainly used for being connected with a hoisting track;
the lifting lug 3 is matched with a lifting hook for use, and the connection mode with the I-shaped steel C6 is welding;
the I-steel B5 and the I-steel A1 are connected by the bolt 2, the purpose of using the bolt is that different I-steels can be configured for use according to the size of an actual track in the later period, and the connection mode with the I-steel C6 is welding and is a fixed mode;
the I-steel C6 is used for supporting the lifting lug 3.
This lifting device can directly promote the track to hugging closely the adjustment backing plate through the lug, no longer need the manpower come jacking track, more does benefit to the construction.
Conventional hoisting method, because the track is heavy, rely on the manpower to jack the track, cause the safety risk easily, the physical power that can save operating personnel is used to this instrument, avoids accident's emergence, effectively reduces the construction risk.
All parts are common parts on the construction site, and the cost is low.
During the use, originally place two or three according to the track length of hoist and mount in the position department that needs hoist and mount, then place the track that needs hoist and mount on lifting device, lock clamp bolt.
Hooking a lifting hook of the chain block on a lifting lug 3 on a lifting tool, slowly lifting the track to be tightly attached to an adjusting base plate according to a lifting command, and requiring two (or three) lifting tools to be lifted simultaneously in the process;
after the welding is finished, the compression bolts can be loosened, and the hoisting tool can slowly descend, so that the welding machine is convenient and practical.
