Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. The embodiment of the present invention is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.

The embodiment provides a subway train wheel disc and brake disc overhauling and mounting platform which is used for a brake disc 6 and a wheel disc 7, and the overall structure of the platform is shown in figure 1. The platform includes lower part unable adjustment base 3, lower part unable adjustment base 3 sets up on table surface 4, lower part unable adjustment base 3 includes first cylinder, the center of first cylindrical upper surface is equipped with the second cylinder, first cylindrical lower surface contacts with table surface 4, the cover has guide post 1 on the second cylinder, 1 bottom of guide post is equipped with first recess, first recess and second cylinder phase-match, be equipped with bearing 5 between the lower surface of guide post 1 and the first cylindrical upper surface, guide post 1 and brake disc 6 and wheel cake 7 phase-match, the outside of guide post 1 is equipped with the cover and is connected at first cylindrical shell, the shell is connected with guide post 1, the outside of shell is equipped with upper portion rotary tray 2, the joint part of the bottom of brake disc 6 and wheel cake 7 exposes outside the bottom of upper portion rotary tray 2. The platform is shown in cross-section in figure 3.

In servicing the assembly of the brake disc 6 and the wheel cake 7, the assembly of the brake disc 6 and the wheel cake 7 is placed over the upper rotating tray 2, and the assembly of the brake disc 6 and the wheel cake 7 is positioned by the guide posts 1. The state when the assembly of the brake disc 6 and the wheel disc 7 is placed above the upper rotating tray 2 is shown in fig. 2.

During the maintenance, because the shell is connected with guide post 1, the guide post below is equipped with bearing 5, utilizes bearing 5 to realize rotating the sub-assembly of the brake disc 6 of placing on the rotatory tray 2 in upper portion and wheel cake 7, and then realizes overhauing the adapting unit in the equidirectional adapting unit of sub-assembly. The guide posts 1, upper rotating tray 2 and housing structure are shown in fig. 4.

Because the connecting part of the bottoms of the brake disc 6 and the wheel cake 7 is exposed out of the bottom of the upper rotating tray 2, a worker can overhaul the connecting part above the combined piece and also can overhaul the connecting part below the combined piece without a turnover device, thereby reducing potential safety hazards and improving overhaul efficiency.

The brake discs 6 include an upper brake disc and a lower brake disc. When the brake disc 6 and the wheel cake 7 which are disassembled are installed, firstly, the brake disc at the lower layer is arranged above the upper rotating tray 2, and the brake disc at the lower layer is positioned through the guide post 1. And hoisting the wheel cake 7, rotating the lower-layer brake disc on the upper rotating tray 2, aligning the mounting hole on the lower-layer brake disc with the mounting hole on the wheel cake 7, hoisting the wheel cake 7 onto the lower-layer brake disc, penetrating the aligned holes on the lower-layer brake disc and the wheel cake 7, and mounting a positioning pin and a bolt. And then an upper brake disc is installed, the assembly of the lower brake disc and the wheel cake 7 on the upper rotating tray 2 is rotated, so that the positioning pins on the lower brake disc and the wheel cake 7 are aligned with the installation holes on the upper brake disc, after the alignment, the upper brake disc is placed on the wheel cake 7, the positioning pins and the bolts are installed, finally, the assembly of the brake disc and the wheel cake 7 is formed, and the installation of the brake disc 6 and the wheel cake 7 is completed.

In some embodiments, the bottom of the first cylinder is provided with a second groove, the bottom of the second cylinder extends into the second groove, and the lower surface of the second cylinder is in contact with the work table 4. The second groove is beneficial to weight reduction, and the second cylinder is prolonged to the working table surface, so that the second cylinder is more stable, and the stability of the guide column 1 is improved.

In some embodiments, the first cylinder has a cavity therein and the second cylinder has a bottom extending from a top of the cavity to a bottom of the cavity.
