Description

Technical Field

[0001] The present application relates to the technical field of anti-corrosion spraying of bridge connectors, and specifically to a walking bracket for spraying anti-corrosion coatings on railway bridge connectors. Background Art

[0002] In order to improve the anti-corrosion ability of railway bridge assembly-type bridge deck connection devices, swivel ball joints, bridge bearings and other railway bridge connectors, a layer of anti-corrosion paint needs to be sprayed on the surface. The spraying of anti-corrosion paint is usually completed on the painting line. Since most bridge connectors have a large weight, they need to be equipped with a special transport trolley to enter and exit the paint room normally during painting. The existing paint trolley needs to be equipped with a special support platform when transporting bridge connectors. Since the models of bridge connectors are different, their sizes are also inconsistent, so the support platform installed on the transport trolley is not universal. When users spray paint different models of bridge connectors, they need to spend more time to fix the bridge connectors, which leads to low painting efficiency of bridge connectors.
