In order to achieve the above object, the present invention adopts the following technical solutions, including:
the lifting part and the matching part prefabricated on the large-diameter jacking pipe; the lifting part comprises a lifting beam, lifting lugs connected to the lifting beam, lifting ropes connected to two ends of the lifting beam respectively and a bolt connected to the end parts of the lifting ropes; the matching part comprises two pairs of sleeves prefabricated on the outer peripheral surface of the large-diameter jacking pipe, the two pairs of sleeves are respectively arranged on two sides of the large-diameter jacking pipe and are in mirror symmetry;
the bolt comprises a cylindrical bolt body, the front end of the bolt body is connected with the stopper, and the rear end of the bolt body is connected with the bolt cap; the sleeve comprises a sleeve body, the left end in the sleeve body is a cylindrical accommodating space, and the accommodating space is communicated with the outside through a cylindrical through hole; an axial through groove is formed in the inner wall of the through hole.
Further, the inner diameter of the through hole is slightly larger than the outer diameter of the bolt body, the width of the through groove is slightly larger than the width of the stopper, and the depth of the through groove is slightly larger than the height of the stopper.
Furthermore, a position marker I is arranged on the peripheral surface of the bolt cap, and the position marker I and the stopper are positioned on an axial connecting line of the bolt body; and a position marker II is arranged on the end face of the sleeve body and is positioned at the top of the through groove.
The utility model relates to an mousing-hook hoist for major diameter push pipe, this mousing-hook hoist simple structure, it is convenient to use, can prevent the bolt roll-off sleeve at the in-process that lifts by crane, has avoided the emergence of accident, has ensured safety in production, has improved production efficiency.

Detailed Description
The present invention will be described in further detail with reference to the attached drawings so as to enable those skilled in the art to more clearly understand the invention.
As shown in fig. 6 and 7, the present invention includes:
the lifting part and the matching part prefabricated on the large-diameter jacking pipe; the lifting part comprises a lifting beam 1, lifting lugs 2 connected to the lifting beam, lifting ropes 3 respectively connected to two ends of the lifting beam and a bolt 4 connected to the end parts of the lifting ropes; the matching part comprises two pairs of sleeves 5 prefabricated on the outer peripheral surface of the large-diameter top pipe 6, and the two pairs of sleeves are respectively arranged on two sides of the large-diameter top pipe and are in mirror symmetry;
as shown in fig. 1 and 2, the bolt comprises a cylindrical bolt body 4-1, the front end of the bolt body is connected with a stopper 4-2, and the rear end of the bolt body is connected with a bolt cap 4-3;
as shown in fig. 3 and 4, the sleeve comprises a sleeve body 5-1, the left end in the sleeve body is a cylindrical accommodating space 5-2, and the accommodating space is communicated with the outside through a cylindrical through hole 5-3; the inner wall of the through hole is provided with an axial through groove 5-4.
Further, the inner diameter of the through hole is slightly larger than the outer diameter of the bolt body, the width of the through groove is slightly larger than the width of the stopper, and the depth of the through groove is slightly larger than the height of the stopper.
The inner diameter of the through hole is slightly larger than the outer diameter of the bolt body, the width of the through groove is slightly larger than the width of the stopper, and the depth of the through groove is slightly larger than the height of the stopper, so that the bolt body and the stopper can slide left and right in the through hole and the through groove at the same time.
