Description

Technical Field

[0001] The invention belongs to the field of track cantilever quick-installation maintenance platforms, and in particular relates to a track-based movable manned device and method. Background Art

[0002] In daily maintenance work, we are exposed to a lot of high-altitude operations near the edge. When the equipment is in a suspended position near the edge, and the equipment is long and there are many maintenance points along the line, how to ensure that the maintenance personnel can reach the maintenance position safely is a great challenge for the operators. At present, the general method is to use a lifting equipment to lift the hanging basket to transfer the maintenance personnel to the suspended part that needs maintenance, and the operators stand in the hanging basket to carry out the suspended work near the edge; the second is to install a permanent maintenance platform at the part that needs maintenance. However, both of the above methods have certain disadvantages; for example, the first crane lifting basket manned solution has a limited activity area. If the lifting equipment cannot reach the site under such environmental conditions, the solution cannot meet the on-site maintenance needs. The second permanent maintenance platform solution can solve the maintenance needs of maintenance personnel in suspended parts near the edge, but the annual safety review of the platform itself is a large project for maintenance personnel, especially for equipment with a long maintenance distance. The maintenance workload of the permanent maintenance platform is even greater. Secondly, the frequency of use of the permanent platform is low, and the cost-effectiveness is not high when the equipment maintenance workload is carried out once a year. Both of the above solutions cannot meet the maintenance needs of long-distance equipment suspended parts, nor can they meet the fast, efficient and safe maintenance concept pursued by modern maintenance.

[0003] To this end, we have invented a track-based movable manned device and method based on the on-site work situation, providing a safe and reliable manned maintenance platform for daily inspection and maintenance needs in an environment where equipment is suspended near the edge and over long distances.
