Embodiment 1

[0037] Example 1: Reference figure 1 For the maintenance platform of a power plant boiler screen superheater disclosed in the present invention, a bearing platform 1, a bearing platform 1 is provided with a guardrail 11, and the upper surface of the carrier platform 1 is used to stand the maintenance personnel, and the maintenance personnel need to be used. The maintenance tool is also placed on the bearer platform 1, such as a cutter, grinding machine. A traction device is provided at both ends of the carrier platform 1, and the wire rope 12 is connected to the electric plant boiler, and the upper end of the wire rope 12 is fixed to the power plant boiler, so that the carrier platform 1 can be moved up and down under the action of the traction device. The output box 13 is fixed to the load platform 1, and the output of the distribution box 13 is used to provide power to the overhaul tool.

[0038] refer to figure 1The counter block 2 is provided below the load platform 1, and the...

Embodiment 2

[0043] Example 2: Taking the maintenance process of a power plant boiler screen superheater disclosed in the present invention, a maintenance platform of a power plant boiler screen superheater is used, and the bearing platform 1 is placed in the power plant boiler, and When the carrier platform 1 is raised, the coupling frame 2 is placed below the bearing platform 1, and when the carrying platform 1 is moving upward, the traction rope 4 is connected between the coupling frame 2 and the carrier platform 1. Addition with the upward movement of the carrier platform 1; when the carrier platform 1 reaches the need to have a position, the first clip 82, the intermediate block 81 and the second clip 83 are clamped by rotating the eccentric wheel 85. Thus, the length of the traction rope 4 is fixed, and then the maintenance personnel will use the maintenance tool to operate.

Abstract

The invention relates to an inspection platform and inspection process for a panel-type superheater of a boiler in a power plant, which includes a bearing platform capable of carrying maintenance personnel, and a power distribution box is fixedly arranged on the bearing platform, and the output of the power distribution box is used to connect the maintenance personnel With a maintenance tool, a counterweight frame is arranged below the bearing platform, and at least four traction ropes are fixed on the counterweight frame, and the four traction ropes are respectively located at the four corners of the bearing platform, and the traction ropes are connected to the bearing Between the platform and the counterweight frame, a pulley is arranged on the bearing platform, the traction rope is threaded on the pulley, and a fixing device for fixing the elongation of the traction rope is arranged on the bearing platform. The invention has the effect of relatively firm fixing of the bearing platform and convenient operation by maintenance personnel.

Description

Technical field [0001] The present invention relates to the technical field of screen superheater, in particular, involving a maintenance platform and maintenance process of a power plant boiler screen superheater. Background technique [0002] The screen supermaker is also typically referred to as a semi-radiant superheater, refers to the heat-free heat of the direct radiation heat which is arranged in the upper or furnace outlet of the furnace, and the heat-free heat of the furnace is accepted. The screen superheater maintains a large distance between the two screens, which can reduce the furnace export flue gas temperature and the role of staining, prevent the rear heat-up surface slope. At the same time, it is also the main component of the thermal surface of the modern large boiler, and the overheater of the screen superheater has always been one of the difficulties in the power plant in the furnace. The height of the screen superheater is generally 65 meters to 85 meters. a...
