Description

Technical Field

[0001] The invention relates to the technical field of large equipment hoisting, and in particular to a gantry hanger for a prefabricated cabin type substation and a hoisting method thereof. Background Art

[0002] A prefabricated cabin substation is a type of substation that uses a prefabricated cabin structure and integrates the main equipment of the substation (such as transformers, high-voltage switchgear, secondary protection equipment, etc.); its notable features include high integration, modularization and factory production; the prefabricated cabin substation completes the production, assembly, wiring and preliminary commissioning of all main equipment in the factory through a fully automated production line, and then is transported to the site as a whole unit for simple installation and commissioning before being put into operation. For example, the existing public document CN116667205A-Prefabricated cabin substation discloses a prefabricated cabin substation; Because the prefabricated cabin substation is a highly integrated electrical device, its overall weight is relatively large. Therefore, when the prefabricated cabin substation is transported, the staff needs to use a gantry hanger to lift the prefabricated cabin substation. For example, the existing public document CN115009988A-A gantry hanger for a prefabricated cabin substation and its lifting and the existing public document CN216583825U-A mobile gantry hanger for a substation both disclose a gantry hanger for lifting a substation. Although the existing gantry hanger can realize the lifting of the substation, the existing gantry hanger still has the following deficiencies in actual use: 1. When the existing gantry hanger is in use, in order to achieve the stability of the substation lifting, the staff needs to first tie up the entire substation with a traction rope, and then the staff hangs the traction rope through the gantry hanger to achieve lifting. However, in this lifting method, the staff needs to climb and tie on the substation, which is complicated and labor-intensive. 2. When the staff uses the support traction rope to tie up the substation, the support traction rope on one side of the substation is tightened, and the overall setting is triangular, which causes the contact position between the upper end of the substation and the support traction rope to be too concentrated, and the force on the upper end of the substation is also relatively concentrated. This leads to low bundling stability of the substation on the one hand, and friction of the support traction rope on the other hand, causing damage to the substation; Therefore, it is necessary to improve the prior art to solve the above-mentioned technical problems. Summary of the invention

[0003] The purpose of this section is to summarize some aspects of embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and the invention title of this application to avoid blurring the purpose of this section, the specification abstract and the invention title, and such simplifications or omissions cannot be used to limit the scope of the present invention.

[0004] In view of the problem that when the above-mentioned existing gantry crane is used to lift the prefabricated cabin type substation, the staff needs to manually tie the support traction rope to the outside of the substation, which is complicated and labor-intensive to operate, a gantry crane for a prefabricated cabin type substation is proposed.

Because of the meshing arrangement of the fourth gear plate and the second gear plate and the meshing arrangement of the first bevel gear and the second bevel gear, the winding rollers on the two bundling components can rotate synchronously, thereby realizing the synchronous retraction and release of multiple branch traction ropes, so that the staff can bundle the branch traction ropes to the substation without climbing the substation, and tighten the branch traction ropes for lifting after the bundling is completed. This design is simple to operate, does not require the staff to perform climbing operations when bundling the substation, and effectively reduces the labor intensity of the staff.

[0012] In view of the problem that the existing gantry hanger has unreasonable binding and easily causes damage to the substation when lifting the substation, the gantry hanger for a prefabricated cabin type substation of the present invention is further optimized and improved, wherein: the guide assembly includes a rotating disk, a guide rod, a screw rod and a movable rod, one end of the guide rod is fixed on the side wall of the rotating disk, and the two ends of the rotating disk are symmetrically fixed with first toothed disks, and the first rotating column fixed in the rotating disk passes through the two first toothed disks, and the two ends of the first rotating column are respectively rotatably sleeved on the upper cover plate and the lower cover plate through rolling bearings; the first toothed disks on the same group of two guide assemblies are meshed, and the diameters of the first toothed disks on the two guide assemblies are different, and the first toothed disk with a larger diameter is meshed with the gear column.

The setting of the ball 105a-1 can reduce the friction of the T-shaped column 105a on the fourth toothed disc 104c-2 when the fourth toothed disc 104c-2 rotates.

[0044] Example 3 Reference Figure 2 , Figure 4 , Figure 6 , Figure 7 and Figure 8 , which is the third embodiment of the present invention, is based on any of the above embodiments, except that, in order to better implement the present device, the structure of the guide component 101 is concretized.

[0045] Specifically, the guide assembly 101 includes a rotating disk 101a, a guide rod 101b, a screw rod 101c and a movable rod 101d, one end of the guide rod 101b is fixed on the side wall of the rotating disk 101a, and the first toothed disks 101a-1 are symmetrically fixed at both ends of the rotating disk 101a, and the first rotating column 101a-2 fixed in the rotating disk 101a penetrates the two first toothed disks 101a-1, and the two ends of the first rotating column 101a-2 are respectively rotatably sleeved on the upper cover plate 103a and the lower cover plate 103b through rolling bearings; the first toothed disks 101a-1 on the same group of two guide assemblies 101 are meshed, and the diameters of the first toothed disks 101a-1 on the two guide assemblies 101 are different, and the first toothed disks 101a-1 with a larger diameter are meshed with the gear column 104d; When the above arrangement is in use, the rotation of the first gear disc 101a-1 with a larger diameter in the same group can be realized through the rotation of the gear column 104d. Because the first gear discs 101a-1 in the two guide assemblies 101 in the same group are meshed, the two guide assemblies 101 in the same group can rotate towards or oppositely, thereby completing the adjustment of the angle between the two guide assemblies 101, thereby avoiding excessive concentration of force on the upper substation when the support traction rope 102c is hoisted.

[0046] The movable rod 101d is slidably sleeved on the free end of the guide rod 101b. A fixing plate 101d-1 is fixedly arranged on the bottom surface of the movable rod 101d close to the rotating disk 101a. A screw rod 101c is spirally sleeved on the fixing plate 101d-1, and one end of the screw rod 101c is embedded in the output end of the first motor 101c-1. The first motor 101c-1 is fixedly arranged on the bottom surface of the guide rod 101b, and the axis of the screw rod 101c is arranged parallel to the long side of the guide rod 101b. When the above arrangement is in use, the rotation of the screw rod 101c can be realized through the operation of the first motor 101c-1. Due to the spiral matching arrangement between the screw rod 101c and the fixed plate 101d-1, the movable rod 101d can be moved relative to the guide rod 101b in the axial direction of the screw rod 101c, thereby adjusting the lowering position of the support traction rope 102c according to the size of the substation.

[0047] Furthermore, an L-shaped guide groove 101b-1 is opened on the guide rod 101b along the long side direction, and the free end of the branch traction rope 102c slides through the guide groove 101b-1 and the end face of the movable rod 101d in sequence, and the free end of the branch traction rope 102c extending to the outside of the movable rod 101d is bundled into a bundling sleeve through a fixing buckle 102c-1, so that the branch traction rope 102c can better cooperate with the substation.

[0048] Example 4 This embodiment is the fourth embodiment of the present invention, and this embodiment provides a method for hoisting a gantry hanger for a prefabricated cabin-type substation. Specifically, the hoisting operation is performed according to the following steps: S1: By moving the hoisting mechanism 200, the bundling mechanism 100 is moved to the top of the substation to be hoisted, and the bundling mechanism 100 is moved down and placed on the top surface of the substation. In order to avoid damage to the substation caused by the cooperation between the bundling mechanism 100 and the substation, a protective pad can be added between the substation and the bundling mechanism 100 in actual use; S2: adjusting the angle between the two guide assemblies 101 in the same group according to the size of the substation, and at the same time adjusting the position of the movable rod 101d on the guide rod 101b; S3: After the adjustment is completed, the driving assembly 104 controls all the branch traction ropes 102c to be released synchronously. After the release is completed, the staff ties the free ends of the branch traction ropes 102c to the reserved tying columns of the substation; S4: After the bundling is completed, the traction rope 102c is rolled up to tighten the substation; S5: Finally, the substation is lifted by moving the lifting mechanism 200.
