Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, specifically to a multi-purpose lifting equipment for a super centrifuge. Background Technology

[0002] During the disassembly and maintenance of supercentrifuges in various recycling areas of chemical technology companies, it is often necessary to lift the supercentrifuge body, differential gear, and motor for maintenance. In this process, we sometimes encounter many obstacles that prevent the work from being completed smoothly.

[0003] For example, the hoisting tools installed on-site cannot independently complete the disassembly and hoisting of the super centrifuge. In this case, scaffolders need to build additional scaffolding to assist in the hoisting. This is very time-consuming and labor-intensive, causing great inconvenience to maintenance work. Sometimes, improper scaffolding can easily cause damage to the machine or prevent it from being lifted out of the machine.

[0004] For example, due to their high-speed operation and the high temperature and viscosity of the working medium, tar, in ultracentrifuges, problems frequently arise requiring maintenance. During the disassembly and maintenance of ultracentrifuges, it is often necessary to lift the centrifuge body, differential, motor, etc. However, the lack of adequate on-site lifting tools causes significant inconvenience to the maintenance work.

[0005] According to research, currently in China, maintenance work is mainly carried out by temporary scaffolding erected by scaffolders, and there are no specialized auxiliary hoisting tools available. Utility Model Content

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] The present invention will be further described below with reference to the embodiments.

[0026] Example: A multi-purpose lifting tool for a super centrifuge, as shown in the attached document. Figure 2 - Appendix Figure 3 The system includes a channel steel 1 and an electric hoist 2. The electric hoist 2 is fixed on the channel steel 1. The front end of the channel steel 1 is provided with an auxiliary lifting structure consisting of two sets of support plates 3 and a support rod 4. The support rod 4 is sleeved on both sides of the two sets of support plates 3. Each set of support plates 3 includes a bottom plate 31, a support plate 33 fixed perpendicularly to the bottom plate 31, and a top plate 35 fixed to the top of the support plate 33. A top reinforcing plate 34 is fixed between the top plate 35 and the support plate 33. A bottom reinforcing plate 32 is fixed between the support plate 33 and the bottom plate 31. The support rod 4 is sleeved in the top plate 35 and fixedly connected on both sides by nuts 41. A hook 5 is fixed in the middle of the support rod 4.

[0027] For reference Figure 1 In existing technical solutions, the method of erecting scaffolding 6 on the spot is often adopted. The scaffolding 6 is erected on the front end of the channel steel 1, and hoists are installed on the scaffolding 6 to achieve the purpose of adjustment.

[0028] The base plate 31, support plate 33, and top plate 35 are all L-shaped sheet metal structures. Multiple sets of connecting holes 37 are opened in the middle of the base plate 31, and through holes 36 are opened on both sides of the top plate 35. The mounting rod 4 is a threaded rod structure and is inserted through the through holes 36. The base plate 31 and support plate 33 form an L-shape, and the support plate 33 and top plate 35 form a T-shape. Two top reinforcing plates 34 are provided and fixed to both sides of the support plate 33. The hook 5 can have a square or circular closed cross-section. In practical use…

[0029] (1) Improve labor efficiency. Previously, each maintenance operation required 5 fitters and 2 scaffolders, and 6 hours of work. After using this scaffold, the maintenance work now only requires 4 fitters, 4 hours of work, and 24 hours of work time to complete the maintenance operation. Now, the 6 super centrifuges can be maintained 20 times a year, saving more than 520 hours of work time, and the workload has also been greatly reduced.

[0030] (2) Reduce the loss of spare parts and avoid the loss of spare parts caused by improper hoisting.

[0031] (3) Improved the installation accuracy of the equipment, enabling installation in one step and overcoming the repeated installation caused by inconvenience in the past.

[0032] The usage steps are as follows, taking the hoisting of a super centrifuge as an example:

[0033] (1) First remove the differential safety cover, use M16 bolts to pass through the connection hole on the base plate 31, engage and fix it with the preset hole on the top of the super centrifuge, and fasten the two mounting rods 4 to the top plate 35 with M16 nuts 41.

[0034] (2) Install hoists and adjust their positions. Use the front hoist when you need to lift the motor and the rear hoist when you need to replace the differential. They do not interfere with each other and can be used for multiple purposes, which is convenient and quick.

[0035] (3) When disassembling the centrifuge drum, this lifting tool needs to be used in conjunction with the existing lifting tools to set up the centrifuge's special lifting beam on the machine body, adjust the balance, and attach the hook.

[0036] (4) Lift the drum while adjusting it to prevent it from deflecting or bumping. Slowly lift the drum out. The same applies when reassembling it.

[0037] Through on-site application of the fabricated lifting scaffold during maintenance, it was verified that it fully meets our maintenance requirements, offering convenience, simplicity, and saving time and effort. Furthermore, this multi-purpose scaffold can be fixed in one installation to complete multiple tasks without repeated installation. Disassembly is also convenient; simply remove the nuts and detach the support poles from the side plates.

[0038] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
