Description

Technical Field

[0001] The present invention relates to the technical field of boiler maintenance, and particularly to a support platform for the maintenance of auxiliary equipment of thermal power boilers. Background Art

[0002] As a core link in power production, the auxiliary equipment system of thermal power boilers includes key components such as coal mills, coal feeders, fan groups (including induced draft fans and return air fans), grate devices, and slag removal machinery. Since most of the auxiliary equipment is installed at high altitudes, operators need to rely on lifting platforms to carry out maintenance operations. A typical device in the prior art is the lifting platform for the maintenance of the furnace of a thermal power boiler disclosed in the patent CN212609397U. Its structural design includes a lifting body and a top auxiliary mechanism: the driving motor is integrated in the box body, and the height adjustment of the guardrail is realized through a bevel gear set (including the meshing transmission of the first bevel gear and the second bevel gear), and the operation convenience is improved by matching with a movable panel that can be lowered.

[0003] However, this solution has significant limitations: the positioning of the platform only depends on the braking device of the bottom universal wheels. When the operator is working at high altitudes, there is a lack of multi-directional limiting constraints, and it is difficult to completely eliminate the risk of platform slipping. Especially in an environment with strong air flow disturbance or equipment vibration at high altitudes, a single braking device is prone to a decrease in stability due to changes in ground adhesion, objectively increasing the risk coefficient of personnel falling and restricting the safety operation efficiency under complex working conditions. In response to the above problems, there may already be technical solutions in the prior art, but this case wants to provide an alternative or replacement technical solution. Summary of the Invention
