The lifting appliance firmly supports the lower end of the housing beam through the clamp and the supporting beam in the horizontal lifting and vertical turning processes of the heavy-duty rolling mill housing, so that the safety and reliability of the lifting process are ensured.
Description
Technical Field
The utility model relates to a heavy equipment's hoist and mount field specifically is a hoist of heavy rolling mill memorial archway.
Background
Mill stands are typically the single largest size and weight component of a mill work stand. The housing of the large-scale hot-rolled plate strip rolling mill is large in size and heavy in weight. Because the size is large, the transportation is horizontal, the vertical turning and the installation in place difficulty is large, and a special lifting appliance is generally used for assisting the lifting. The existing common lifting appliance is complex in structure, the two sides of the memorial archway are locked through the clamp, the vertical turnover of the memorial archway is realized, and due to the fact that the center of gravity of the lifting appliance is unstable, certain potential safety hazards exist in the lifting mode.
Disclosure of Invention
An object of the utility model is to provide a new hoist, it can ensure that the rolling mill memorial archway does not meet accident in the hoist and mount operation of rolling mill memorial archway.
In order to achieve the above object, the present invention is realized as follows:
a sling for a heavy mill housing, comprising: the clamp, the lifting lug and the door-shaped frame; the fixture is formed by enclosing box-shaped beam plates, the plane projection of the fixture is rectangular, lifting lugs are arranged at two ends of the fixture, a portal frame is arranged in the center of the top surface of the fixture, the portal frame is erected at the top of the fixture through two connecting beams erected at the top of the fixture, the fixture with the portal frame penetrates through the bottom of the mill housing, the portal frame is located between vertical arms at two sides of the mill housing, and the fixture embraces the mill housing from the outer side; the hoisting equipment is connected with the lifting lugs at the two ends of the clamp, so that the clamp is hoisted and the rolling mill housing is simultaneously taken up, in the process, the portal frame is supported between the vertical arms at the two sides of the rolling mill housing, and the rolling mill housing is prevented from toppling due to gravity center movement.
The heavy-duty mill housing lifting tool is characterized in that a supporting beam is further horizontally arranged on the inner wall of the fixture, and the supporting beam is used for filling a gap between the fixture and the mill housing caused by gravity center shift of the mill housing in the lifting process.
The lifting lugs of the lifting appliance for the housing of the heavy rolling mill are steel columns, the lifting lugs are welded at two end faces of the clamp, and reinforcing rib plates are arranged between the clamp and the lifting lugs.
The lifting appliance is simple in structure and convenient to manufacture and process, and the clamp, the door-shaped frame and the supporting beam are all connected through the bolt, so that the lifting appliance is convenient to disassemble. The lifting appliance firmly supports the lower end of the housing beam through the clamp and the supporting beam in the horizontal lifting and vertical turning processes of the heavy-duty rolling mill housing, so that the safety and reliability of the lifting process are ensured.

Detailed Description
The invention is further illustrated by the following specific examples.
As shown in fig. 1 and 2, a hanger for a heavy mill housing comprises: the device comprises a clamp 1, a lifting lug 2 and a door-shaped frame 3; the fixture 1 is formed by enclosing box-shaped beam plates, the plane projection of the fixture is rectangular, lifting lugs 2 are arranged at two ends of the fixture 1, a portal frame 3 is arranged in the center of the top surface of the fixture 1, the portal frame 3 is erected at the top of the fixture 1 through two connecting beams erected at the top of the fixture 1, the fixture 1 with the portal frame 3 penetrates through the bottom of the mill housing, the portal frame 3 is located between vertical arms at two sides of the mill housing, and the fixture 1 encloses the mill housing from the outer side; the hoisting equipment is connected with the hoisting lugs 2 at the two ends of the clamp 1, so that the clamp 1 is hoisted and the rolling mill housing is simultaneously taken up, and in the process, the portal frame 3 is supported between the vertical arms at the two sides of the rolling mill housing, so that the rolling mill housing is prevented from toppling due to gravity center movement.
The heavy mill housing lifting tool is characterized in that a supporting beam is further horizontally arranged on the inner wall of the fixture 1 and used for filling a gap between the fixture and the mill housing caused by gravity center shift of the mill housing in the lifting process.
The lifting lugs of the lifting appliance for the housing of the heavy rolling mill are steel columns, the lifting lugs are welded at two end faces of the clamp, and reinforcing rib plates are arranged between the clamp and the lifting lugs.
The lifting appliance is simple in structure and convenient to manufacture and process, and the clamp, the door-shaped frame and the supporting beam are all connected through the bolt, so that the lifting appliance is convenient to disassemble. The lifting appliance firmly supports the lower end of the housing beam through the clamp and the supporting beam in the horizontal lifting and vertical turning processes of the heavy-duty rolling mill housing, so that the safety and reliability of the lifting process are ensured.
