Description

Technical Field

[0001] The invention belongs to the technical field of engineering machinery repair, and in particular relates to a lifting device used for repairing engineering machinery equipment. Background Art

[0002] Engineering machinery is an important part of the equipment industry; in general, all mechanical equipment required for earthwork construction, road construction and maintenance, mobile lifting and loading and unloading operations, and comprehensive mechanized construction projects required for various construction projects are called engineering machinery. When a large-scale engineering machinery fails, it is generally divided into simple repairs, replacement of parts, disassembly and repair, and disassembly and replacement according to the size of the problem; since the main parts of the engineering machinery are relatively heavy and large in size, disassembly and repair operations are more difficult; therefore, it is necessary to use lifting equipment to lift and repair the faulty parts.

[0003] Most of the existing lifting equipment is used to lift the vehicle as a whole or the platform, and there is a lack of equipment suitable for lifting parts of large machinery. If large machinery and equipment are to be lifted as a whole, the required lifting weight is extremely large and difficult to achieve; therefore, most of them will disassemble their parts before lifting and maintenance operations.

[0004] In view of the above-mentioned problem of lack of equipment suitable for lifting parts of large machinery, the present invention provides a lifting device for repairing engineering machinery equipment. Summary of the invention

[0005] The purpose of the present invention is to provide a lifting device for repairing engineering machinery equipment.

[0009] As a preferred technical solution of the present invention, the top surface of the lifting beam is equipped with two suspension chains, and the outer ends of the suspension chains are fixedly installed with suspension hooks; the suspension chains and suspension hooks provide a certain degree of suspension support for the suspension state of the components, and share the force from the lifting beam to the synchronous hydraulic cylinder assembly.

[0010] As a preferred technical solution of the present invention, the lifting beam is evenly provided with support slots, and the inner wall of the support slots is matched with support columns; bolts for limiting are fixedly installed at both ends of the support columns; the lifting beam and the support columns provide support for the components.

[0011] As a preferred technical solution of the present invention, hinge seats are provided at both ends of the lifting support beam, and hinged support plates are hinged on the hinge seats; the hinged support plates provide additional supporting points for the parts at positions that are difficult to support, which is beneficial to the overall stability of the parts.

[0012] As a preferred technical solution of the present invention, a central rotating shaft is fixed to the inner end of the articulated support plate, the central rotating shaft is rotationally coordinated with the hinge seat, and reinforcing connecting plates are fixed between the two ends of the central rotating shaft and the articulated support plate; the articulated support plate rotates on a horizontal plane; the function of the central rotating shaft and the reinforcing connecting plate is to strengthen the overall structural strength of the articulated support plate.

[0013] As a preferred technical solution of the present invention, the inner end of the hinged support plate is evenly arrayed with limiting holes, and the inner wall of the limiting holes is matched with limiting columns; the limiting holes and limiting columns are used to fix the hinge angle of the hinged support plate.

[0014] As a preferred technical solution of the present invention, the telescopic ends of the two adjacent hydraulic cylinders are respectively slidably matched with the two ends of the reinforcing connecting rod; both ends of the reinforcing connecting rod are hinged with sleeves; the function of the reinforcing connecting rod is to provide a relatively stable structural mutual support effect between multiple adjacent hydraulic cylinders.

[0015] The present invention has the following beneficial effects:
