Description

Technical field:

[0001] The utility model belongs to the technical field of centrifuge disassembly tooling, and more specifically relates to a large centrifuge disassembly tooling. Background technology:

[0002] Existing large-scale liquid-solid separation centrifuges need to be inspected and maintained after being used for a certain period of time. Due to the large size and weight of large-scale liquid-solid separation centrifuges, they are not easy to move. In particular, since the internal drum of the centrifuge needs to be disassembled frequently, the drum is connected and fixed to the centrifuge body by threads. Large-scale liquid-solid separation centrifuges are large in size and heavy in weight. Traditional disassembly tools cannot be disassembled continuously, and a large amount of manpower is required to knock on the drum. Due to the difference in force, there is a difference in the force applied to the drum, which leads to a poor fit between the drum and the centrifuge, which is not conducive to reinstallation after maintenance. The different force will also cause deformation inside the drum, affecting the centrifugal effect. Utility model content:

[0003] In order to solve the above problems and overcome the shortcomings of the prior art, the utility model provides a large centrifuge disassembly tool;

[0004] The technical problem to be solved is: large liquid-solid separation centrifuges are large in size and heavy in weight. Traditional disassembly tools cannot be used for continuous disassembly, and a large amount of manpower is required to knock on the drum. Due to differences in force, there are differences in the force applied to the drum, which leads to poor coordination between the drum and the centrifuge, making it difficult to reinstall after maintenance. Differential force application will also cause deformation inside the drum, affecting the centrifugal effect.

[0005] The specific technical solution of the utility model to solve the above technical problems is: the large centrifuge disassembly tool comprises a base; the upper end surface of one side of the base is provided with a hoisting device for hoisting the centrifuge, characterized in that:

[0006] The base is provided with a circular slot at the center of the base, and a circular rotating disk is provided inside the side wall of the circular slot for rotation connection, and a fixing device for fixing the outer wall of the centrifuge is provided inside the circular rotating disk.

[0007] A preset number of air hammers are fixed to the upper end surface of the annular turntable in the form of an annular matrix through a bracket, and the output ends of the air hammers act on wrenches through copper hammers; the wrenches are detachably fixed to the drum of the centrifuge through bolts.

[0008] Furthermore, the fixing device is configured as a clamp, which is composed of two U-shaped clips, and both sides of the U-shaped clip are provided with extended edges, which are detachably connected by bolts.

[0009] Furthermore, one of the U-shaped cassettes is fixed on a base or the ground located inside the circular slot.

[0010] Furthermore, a preset number of driving structures for driving the annular turntable to rotate are arranged at the bottom of the base.

[0011] Furthermore, the driving structure includes a reduction motor arranged on the outside of the annular turntable, and the reduction motor is meshed with the outer end surface of the bottom of the annular turntable through a driven gear.

[0012] Furthermore, a limit roller is arranged on the inner side of the circular turntable, and a limit gear is arranged on the outer side of the circular turntable.

[0013] Furthermore, the driven gear, the limiting roller and the limiting gear are rotatably connected to the lower end surface of the base.

[0014] The beneficial effects of the utility model are:

[0015] One advantage of the utility model is that the circular rotating disk with circular motion can be used in conjunction with an air hammer to disassemble the drum of a large liquid-solid separation centrifuge, and the force is applied evenly, which solves the problem that there is a difference in manual force, and there is a difference in the force applied to the drum, resulting in a poor fit between the drum and the centrifuge, which is not conducive to reinstallation after maintenance. The difference in force application will also cause deformation inside the drum, affecting the centrifugal effect.

[0016] One advantage of the utility model is that it provides a large centrifuge disassembly tool with a lifting device, which facilitates the station transfer of the large centrifuge or the drum;

[0017] One advantage of the utility model is that a limiting roller is arranged on the inner side of the circular turntable, and a limiting gear is arranged on the outer side of the circular turntable, which can well ensure the stability of the circular turntable and avoid the instability of the circular turntable caused by the reaction force of the air hammer.

[0031] Furthermore, the driven gear 14 , the limiting roller 13 and the limiting gear 12 are rotatably connected to the lower end surface of the base 1 .

[0032] It should be noted that the utility model is a large centrifuge disassembly tool. When working,

[0033] 1. The pre-disassembled large centrifuge is hoisted into the fixing device 5 in the circular slot 7 by using the hoisting device 15, wherein the hoisting device 15 is preferably a cantilever crane, and the fixing device 5 is preferably a clamp, which is composed of two U-shaped cassettes, and the two sides of the U-shaped cassette are provided with outer edges, and the outer edges are detachably connected by bolts, wherein one of the U-shaped cassettes is fixed on the bottom plate or the ground located inside the circular slot 7;
