AI Technical Summary
The welding requirements for existing modular substation lifting lugs are high, the inspection process is complicated and there are safety hazards. In addition, welding lifting lugs is costly, takes up space and poses safety risks.
The design adopts a detachable lifting lug, and replaces welding with bolt connection. The lifting lug body is fixed to the substation shell with bolts and nuts, and reinforcing ribs and plates are added to improve support strength and stability.
It reduces welding and inspection workload, lowers project costs, and the lifting lugs are reusable and can be removed during transportation to reduce the risk of bumps and collisions, thus improving safety.

Description
TECHNICAL FIELD
[0001] The utility model relates to modular substation technical field especially relates to modular substation detachable lifting lug. BACKGROUND
[0002] Modular substation needs to integrate ring network cabinet, transformer, low voltage cabinet, switch cabinet and a series of equipment in the inside after the shell structure is prefabricated in the factory, leads to the whole module unit is relatively heavy.
[0003] Prior art adopts welding lifting lug on the both sides of module shell bottom, is used for hoisting, operation, this scheme although satisfies the functional demand, but also encountered the following several problems in the subsequent process:
[0004] 1, the technical requirement of lifting lug is high, and the procurement cost is high;
[0005] 2, the welding requirement of lifting lug as hoisting bearing piece is high, and the difficulty is big;
[0006] 3, the weld of lifting lug needs to do ultrasonic detection, and the procedure is complicated;
[0007] 4, lifting lug protrudes the box, occupies the space, and has the security risk in the transportation process. UTILITY MODEL CONTENTS
[0008] The utility model discloses modular substation detachable lifting lug is provided to solve the technical requirement of lifting lug in the background art, welding requirement, detection procedure is complicated and has the problem of security risk.
[0009] In order to realize the above purpose, the utility model adopts the following technical scheme:
[0010] Modular substation detachable lifting lug, including lifting lug body and substation shell, the one end of lifting lug body away from substation shell is equipped with mounting hole, the one end of lifting lug body away from mounting hole is fixedly connected with mounting plate, the mounting plate is equipped with the multiple bolts of symmetry on the threaded insertion, the substation shell is equipped with the threaded hole corresponding to bolt, the one end of bolt in the substation shell is threaded with the nut of sleeve joint.
[0011] Preferably, the both sides outer walls of lifting lug body close to mounting hole are all fixedly welded with the reinforcing rib.
[0012] Preferably, the outer wall of substation shell is equipped with the installation slot corresponding to mounting plate.
[0013] Preferably, the inner wall of substation shell is fixedly welded with the reinforcing plate corresponding to bolt.
[0014] Compared with the prior art, the utility model has the advantages of the following:
[0015] In the utility model, the lug is changed from welding fixation to bolt connection, thereby greatly reducing welding and detection workload; meanwhile, the lug can be repeatedly used, thereby reducing project cost; the lug is installed during hoisting and removed during transportation, thereby preventing bumping and reducing safety hazards.
