Abstract
The utility model relates to a drilling and production engineering equipment technical field, in particular to embedded box-packed lug. The device comprises a box body with an open upper part, a hinge pin is connected in the box body, a lifting lug is sleeved on the hinge pin and can rotate around the hinge pin, the lifting lug can rotate into the box body around the hinge pin and does not protrude out of the box body, a lifting groove is designed at the top of the lifting lug, and a drain hole is formed in the bottom of the box body. The utility model discloses a link together the lug through round pin axle and a side box, when not at ordinary times, the lug is kept flat in the square box, can not the salient structure plane, does not influence spread hyacinth bean decorative pattern steel sheet or steel barrier above the structure, pulls with one hand when the lug uses, and the lug just can be erect, accomplishes the hoist and mount operation, convenient to use, and occupation space is little.
Description
The technical field is as follows:
the utility model relates to a drilling and production engineering equipment technical field, in particular to embedded box-packed lug.
Background art:
in the manufacturing process of heavy equipment such as a drilling machine, lifting lugs are needed to assist in completing assembling and welding of a steel structure in many places. Common lifting lugs welded on the structures can protrude the structural planes, however, some structures need to be paved with hyacinth bean pattern steel plates or steel grids, smoothness is required on the structures, the lifting lugs are vertically welded, people can have the danger of stumbling feet, and the structure does not meet the requirements of the specification or users; the side direction welding is carried out in a place with narrow space, no operation space exists, and the hoisting operation cannot be finished; and during the side direction welding, the operation space that hoist and mount needs is big, and the planking or steel barrier trompil are great, need design apron.
The utility model has the following contents:
the to-be-solved technical problem of the utility model is to provide an embedded box-packed lug, the device have realized linking together the lug through round pin axle and a side box, when not at ordinary times, the lug is kept flat in the square box, can not the salient structure plane, does not influence spread hyacinth bean decorative pattern steel sheet or steel barrier above the structure, pulls with one hand when the lug uses, and the lug just can erect, accomplishes the hoist and mount operation, convenient to use, and occupation space is little. The defect that the operation space of the existing lifting lug welding operation is insufficient due to the fact that the structural plane can be protruded to influence the paving of a hyacinth bean pattern steel plate or a steel barrier on the structure and the side face welding and hoisting operation is overcome.
The utility model adopts the technical proposal that: an embedded box-packed lifting lug comprises a lifting lug; the box body is characterized by further comprising a box body with an open upper portion, a hinge pin is connected in the box body, a lifting lug is sleeved on the hinge pin and can rotate around the hinge pin, the lifting lug can rotate into the box body around the hinge pin and does not protrude out of the box body, a lifting groove is designed at the top of the lifting lug, and a drain hole is formed in the bottom of the box body.
The box body is formed by connecting a bottom sealing plate, a left sealing plate, a right sealing plate, a front sealing plate and a rear sealing plate.
The end part of one end of the lifting lug rotating around the pin shaft is designed to be arc-shaped.
The utility model has the advantages that: the utility model discloses a link together the lug through round pin axle and a side box, when not at ordinary times, the lug is kept flat in the square box, can not the salient structure plane, does not influence spread hyacinth bean decorative pattern steel sheet or steel barrier above the structure, pulls with one hand when the lug uses, and the lug just can be erect, accomplishes the hoist and mount operation, convenient to use, and occupation space is little.
Description of the drawings:
the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a sectional view taken along line a-a of fig. 1.
Fig. 3 is a top view of the present invention.
The specific implementation mode is as follows:
as shown in fig. 1, 2 and 3, the embedded box-mounted lifting lug comprises a lifting lug 3; still include the open box body in upper portion 1, box body 1 in-connection round pin axle 2, 3 suits of lug are on round pin axle 2 and can rotate around round pin axle 2, and lug 3 can change over to box body 1 inside and not protrusion box body 1 around round pin axle 2, and the design in 3 tops of lug has the recess of wrenching, conveniently wrenches lug 3, and open 1 bottoms of box body has wash port 4, prevents ponding in the box body 1.
The box body 1 is formed by connecting a bottom sealing plate, a left sealing plate, a right sealing plate, a front sealing plate and a rear sealing plate.
The end part of one end of the lifting lug 3 rotating around the pin shaft 2 is designed to be in an arc shape.
When the lifting lug 3 is not in work, the lifting lug 3 is flatly placed in the box body 1, and when the lifting operation is needed, the lifting lug 3 is pulled up from the box body 1 by hands or other tools to carry out the lifting operation.
It should be understood that the above detailed description of the present invention is only for illustrating the present invention and is not limited by the technical solutions described in the embodiments of the present invention, and those skilled in the art should understand that the present invention can still be modified or equivalently replaced to achieve the same technical effects; as long as the use requirement is satisfied, the utility model is within the protection scope.
