Description

Technical Field

[0001] The utility model belongs to the technical field of centrifuge maintenance, and particularly relates to a detachable large gear shaft placement tool. Background Art

[0002] When overhauling the centrifuge head, the large gear shaft needs to be removed and lifted out of the gear box. Due to the large size and heavy weight of the large gear shaft, how to properly and safely place the removed large gear shaft becomes a problem faced during the overhaul process. If the large gear shaft is not handled properly, it may not only cause damage to the workpiece, affecting its service life and performance, but also pose a serious safety threat to the operator and even cause work-related accidents. Summary of the invention

[0003] In response to the problems existing in the prior art, the utility model provides a detachable large gear shaft placement tooling, which adopts a flexible assembly method and can build a stable gear shaft placement support platform with simple operations. It can maintain a good balance when bearing forces in different directions, ensuring greater stability when under force and reducing the risk of shaking or tipping over due to uneven force.

[0004] The utility model is implemented as follows: a detachable large gear shaft placement tool comprises two support frames of the same structure, the two support frames are symmetrically arranged on both sides of the gear, and are used to support the gear shafts on both sides of the gear, and the support frames comprise a support body and a support foot assembly arranged on the lower end surface of the support body;

[0005] The upper end surface of the support body is provided with a trapezoidal groove for accommodating the gear shaft, and the outer circle contour of the gear shaft is tangent to the hypotenuse of the trapezoidal groove;

[0006] The support leg assembly includes three support rods arranged on the lower end surface of the support body, the three support rods form a conical support structure, the lower end surface of the support body is vertically provided with a vertical rod, and the vertical rod and the support rod are all connected to the support body by threads.

[0007] Furthermore, the vertical poles of the two support frames are connected to each other through a fixing rod, and both ends of the fixing rod are provided with threaded sections, and the threaded sections of the fixing rod penetrate the vertical poles and are fixed by nuts. The fixing rod can form the two support frames into a more stable overall structure, ensure the overall stability of the support structure, and increase the rigidity between the two support frames, so as to better resist external loads and deformation and improve the bearing capacity.

[0008] Furthermore, the mounting surface of each support rod and the support body is an inclined surface structure, and the mounting surface is perpendicular to the axis of the support rod. The mounting surface of the inclined surface structure can more easily achieve accurate docking with the support rod, thereby improving the accuracy of installation.

[0009] Furthermore, a foot pad is provided at the supporting end of each support rod. The foot pad can increase the contact area between the support rod and the ground, thereby improving the stability of the overall tooling. The foot pad can be made of materials such as rubber or silicone, effectively preventing the support rod from sliding on a smooth or wet ground, and adapting to different ground requirements.

[0010] The utility model has the following advantages and technical effects: due to the adoption of the above technical scheme and a flexible assembly method, a stable gear shaft placement support platform can be built with simple operations, which can maintain a good balance when subjected to forces in different directions, ensuring greater stability when subjected to forces, and reducing the risk of shaking or tipping over due to uneven force.
