Embodiment Construction
[0010] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, the power supply box 2 is installed on the frame 1 of the electric locomotive, and the four corners of the bottom plate 3 of the power supply box 2 are fixed with a self-positioning and fixing device for the power supply box of the electric locomotive. The self-positioning and fixing device for the power supply box of the electric locomotive includes a positioning block 4. The positioning block 4 is inclined to the surface of the power box 2, and the contact surface with the bottom plate 3 of the power box is a vertical surface. There is a positioning pin 6 in the positioning block 4. The positioning pin 6 is equipped with a spring 11 at the inner end of the positioning block 4. In the positioning Pull groove 8 is arranged on block 4 sidewalls, pull rod 10 is arranged in pull groove 8, and the inner end of pull rod 10 is fixed on the dowel pin 6, and the outer end of pull rod 10 is equipped with rotating ha...

The invention discloses an electric locomotive power box fixing device and method. The surface, opposite to a power box, of a positioning block is an inclined plane, the surface, in contact with a power box bottom plate, of the positioning block is a vertical plane, a positioning pin is arranged in the positioning block, a spring is arranged at the position, on the inner end of the positioning block, of the positioning pin, a pull groove is formed in the side wall of the positioning block, a pull rod is arranged in the pull groove, the inner end of the pull rod is fixed on the positioning pin,the outer end of the pull rod is provided with a rotary handle through a bolt, and a handle stop block is arranged beside the pull groove. The device and method have the beneficial effects that the three-dimensional accurate positioning of the power box is achieved, and the safety and stability of an electric locomotive are improved; a sliding distance is formed between the power box bottom plateand the inclined plane of the positioning pin, the impact force generated when the power box makes direct rigid contact with a frame is relieved, so that the impact on a storage battery and the locomotive is reduced; and the labor intensity of operators is relieved, the productivity is improved, and the advantages are obviously embodied on the power box with a large tonnage.
Description
technical field [0001] The invention relates to a fixing device and method for a power supply box of an electric locomotive. Background technique [0002] At present, the battery power box of the electric locomotive is fixed by pins and holes. Since the power box is frequently rotated, it is difficult to align the four positioning pin holes each time during the rotation installation, and the labor efficiency is not high. Contents of the invention [0003] The object of the present invention is to provide a fixing device and method for a power supply box of an electric locomotive. [0004] The purpose of the present invention is achieved by the following methods: a power box fixing device and method for electric locomotives, the positioning block is an inclined plane relative to the power box surface, and the contact surface with the bottom plate of the power box is a vertical surface, and there are positioning pins in the positioning block. The pin is equipped with a spri...
