Description

Technical Field

[0001] The invention relates to the field of locomotive bogies, and in particular to a hoisting device and a hoisting method for sand box assembly. Background Art

[0002] In the locomotive manufacturing industry, in order to improve the state of the wheel-rail contact surface, prevent the wheels from spinning, and increase adhesion traction, sand boxes are set at the four corners of the bogie. A sand spreading valve is set at the bottom of the sand box to spread the sand in the sand box.

[0003] In the prior art, when installing the sand spreading valve at the bottom of the sand box, due to the lack of a dedicated assembly platform, the sand box needs to be placed on the ground, flipped over so that the bottom faces upward, and then the sand spreading valve is installed. This method is not only laborious, but also has certain safety risks. At the same time, the sand box is hoisted and transported individually during each link of the transportation process, which wastes time.
