Boiler furnace safety net

Abstract

The invention discloses a safety net of a boiler hearth. The safety net comprises two upper sliding rails, two lower sliding rails, multiple upper sliding trolleys and multiple lower sliding trolleys, wherein the two upper sliding rails, which are parallel to each other, are arranged at the front and rear ends of a hearth steel structure and in the same horizontal plane; the two lower sliding rails, which are parallel to each other, are arranged at the front and rear ends of the hearth steel structure and below the two upper sliding rails respectively; the upper sliding trolleys are arranged on the two upper sliding rails through a roller wheel I in a sliding manner; the lower sliding trolleys are arranged on the two lower sliding rails through a roller wheel II in the sliding manner; a hanging hole I and a hanging hole II are formed in each upper sliding trolley and each lower sliding trolley, respectively. Through a power device, an upper safety net and an lower safety net can be rapidly opened and closed by virtue of moving of the upper sliding trolleys along the upper sliding rails and moving of the lower sliding trolleys along the lower sliding rails; the use is simple, the device lifting efficiency is guaranteed, safety protection requirement is met, and the safety protection time gap during the arrangement of a traditional safety net is shortened.

Description

technical field [0001] The invention relates to a safety protection device, in particular to a safety net. Background technique [0002] During the installation of power station boilers, due to the large height difference between the upper and lower sides, and the equipment is often lifted from the middle of the furnace during the construction process, the original technology pulls a fixed safety net in the middle of the boiler furnace. After the equipment is hoisted, it needs to be manually restored. This process consumes a lot of labor, and the safety net cannot be opened and restored quickly, which increases safety risks. Contents of the invention [0003] In order to overcome the deficiencies of the above technologies, the present invention provides a boiler furnace safety net that can be quickly opened and closed. [0004] The technical scheme that the present invention overcomes its technical problem adopts is: [0005] The boiler furnace safety net includes two up...

Problems solved by technology

[0002] During the installation of power station boilers, due to the large height difference between the upper and lower sides, and the equipment is often lifted from the middle of the furnace during the construction process, the original technology pulls a fixed safety net in the middle of the boiler furnace. After the equipment is hoisted, manual restoration is required. This process consumes a lot of labor, and the safety net cannot be quickly opened and restored, and at the same time increases safety risks.
