Embodiment Construction
[0020] The present invention will be further described below in conjunction with specific examples.
[0021] A cabinet door guiding and positioning device for a locomotive, such as Figure 1~Figure 4 As shown: the positioning block 1 integrally formed by the guide positioning device, the positioning block 1 is a cylindrical ring, that is, the outer surface is cylindrical, the bottom surface is a plane, and the top surface is a concave circular table top. The positioning block 1 The inner hole is a threaded hole; two stepped bolt holes are radially and symmetrically opened on the ring body of the positioning block 1, and the axes of the stepped bolt holes are perpendicular to the bottom surface of the positioning block.
[0022] In this embodiment, a preferred solution is adopted, and the positioning block 1 is made of nylon material.

The invention discloses a cabinet door guide positioning device for a locomotive, and also discloses a traction transformer cabinet applied to a cabinet door guide positioning device for the locomotive, and relates to the field of rail locomotive cabinet door installation. The guide positioning device is an integrally formed positioning block, the positioning block is of a cylindrical ring shape,the peripheral surface is cylindrical, the bottom surface is a plane, the top surface is a concave circular truncated cone surface, and the inner hole is a threaded hole; and two stepped bolt holes are radially and symmetrically formed in a ring body, and the axes of the stepped bolt holes are perpendicular to the bottom surface of the positioning block. The traction variable-flow cabinet comprises a low-voltage control unit, a high-voltage control unit and an auxiliary change control unit, wherein the high-voltage control unit is located below the low-voltage control unit, a partition layer is arranged between the high-voltage control unit and the low-voltage control unit, the cabinet door guide positioning device for the locomotive is fixed on the front side of the partition layer, and the auxiliary variable control unit is located on the right side of the whole high-voltage control unit; and the number of the guide positioning devices is N, N is greater than or equal to 2, and a screw rod is fixedly arranged at the position, opposite to the guide positioning device, of a cabinet door. The guide positioning device is simple in structure and convenient to install.
Description
technical field [0001] The invention relates to the field of rail locomotive cabinet door installation, in particular to a cabinet door guiding and positioning device for locomotives, which is suitable for cabinet door installation of traction auxiliary converter cabinets. Background technique [0002] The traction auxiliary converter cabinet on the CKD9D AC drive diesel locomotive exported by Lianhe Company to the South African Ministry of Railways converts the three-phase AC power output by the generator into AC-DC-AC and outputs it to the traction motor and auxiliary filter cabinet, thereby realizing Alternating current drive for locomotives. The traction-auxiliary converter is designed with back-to-back mirror symmetry, and is divided into three areas: high-voltage area, low-voltage area and auxiliary transformer output area, with a total of 6 gates. As one of the enclosure components of the traction auxiliary converter cabinet, the door not only reasonably separates th...
