Problems solved by technology
[0003] 1. During the use of the boiler maintenance platform, the safety lock is locked and the platform cannot be lowered.
[0004] 2. The boiler maintenance platform cannot effectively cover the maintenance work surface, and when the staff use the boiler maintenance platform for maintenance work, they cannot reach the working surface for maintenance work
[0005] 3. When the maintenance staff use the boiler maintenance platform for maintenance work, the load-bearing capacity of the lifting point is not up to the standard, which brings serious personal safety hazards and equipment safety hazards

Embodiment Construction
[0023] see figure 1 , the boiler maintenance platform 1 of this embodiment is suspended on the load-bearing beam by a steel wire rope and a sling. Two hoists 3 and two safety locks 4 on the 2. Two hoists 3 are arranged on the left and right sides of the lifting platform 2 respectively, and two safety locks 4 are respectively arranged on the tops of the left and right sides of the lifting platform 2 .
[0024] The hoisting points of the boiler maintenance platform 1 include wire rope hoisting points and personal safety rope hoisting points. The wire rope hoisting points include hoist working wire rope hoisting points and safety lock wire rope hoisting points. Boiler maintenance platform 1 also includes personal safety protection rope, safety belt and anti-fall buckle. The anti-fall buckle is connected with personal safety protection rope and safety belt respectively. Staff can wear safety belt, and personal safety protection rope is connected with personal safety rope lifting ...

The invention provides a hoisting point setting method for a boiler maintenance platform. The hoisting point setting method comprises the step of selecting safety hoisting points, the step of settingthe safety hoisting points, the step of statically testing the safety bearing capacity of the hoisting points and the step of dynamically testing the safety bearing capacity of the hoisting points. The personal safety rope hoisting point and a steel wire rope hoisting point are separately set, and first protective components are arranged at all fixed hoisting points of a bearing beam in a cushioned mode. A hoisting belt is hung on the bearing beam, and an end buckle of a steel wire rope is connected with the hosting belt through a detachable buckle. The lower end of the steel wire rope is connected with the boiler maintenance platform. A balancing weight is placed on a lifting platform; the lifting platform is kept static for a preset period of time after being lifted to a preset positionand is then lowered to the ground; inspection is conducted after the lifting platform is stably stopped; the balancing weight is placed on the lifting platform; the lifting platform is lowered after being lifted to the preset position and is lowered to the ground after operating up and down several times; and inspection is conducted after the lifting platform is stably stopped. The hoisting pointsetting method can ensure the safety in the maintenance process of the boiler maintenance platform.
Description
technical field [0001] The invention relates to the technical field of boiler maintenance, in particular to a method for setting lifting points of a boiler maintenance platform. Background technique [0002] The boiler maintenance of the generator set in the combustion power plant generally uses a special platform for boiler maintenance. The boiler maintenance platform consists of two hoist working wire ropes and two safety lock protection wire ropes to realize the up and down operation and safety protection of the boiler maintenance platform. Each staff member is protected by an independent personal safety protection rope, and the lifting points of the existing "special platform for inspection and maintenance" have the following three defects due to unreasonable settings. [0003] 1. During the use of the boiler maintenance platform, the safety lock is locked and the platform cannot be lowered. [0004] 2. The boiler maintenance platform cannot effectively cover the mainte...
