Embodiment 1

[0034] see Figure 1-2 .

[0035] The high-risk point isolation and closure device 100 includes four racks 10, the four racks 10 form a "well" shape, and a gear 20 is arranged in the middle hole formed by the intersection of the four racks 10, and the gear 20 All mesh with the teeth 12 of the four racks 10, push and pull any of the racks 10, the gears 20 rotate and drive the other three racks 10 to move in different directions to complete the isolation or release action .

[0036] As mentioned above, the four racks 10 form a "well" shape, and a gear 20 meshing with the four racks 10 is arranged at the middle through hole 35 of the "well". It can be understood that only one of the racks 10 needs to be moved, and the other three racks 10 will move simultaneously due to the action of the gears 20 .

[0037] It should be further explained that the “movement” refers to movement when the teeth 12 of the rack 10 mesh with the gear 20 , and it moves along the axial direction of the...

Abstract

The invention discloses a high-risk point isolation and closure device. The high-risk point isolation and closure device comprises four racks; the four racks are arranged in a groined shape in a defining mode; a gear is arranged in a middle hole formed by the four intersecting racks; the gears is engaged with teeth of the four racks; and by pushing and pulling any rack, the gear rotates and simultaneously drives the other three racks to move in different directions, and thus an isolation or isolation removing action can be completed. When contraction needs to be conducted for isolation locking, by pushing any rack to the gear, the other three racks can be driven to contract to the gear, and the purpose of isolation locking is achieved; when isolation needs to be removed, by pulling one ofthe racks outwards, the other three racks are stretched outwards under the action of the gear, and the function of isolation removing is achieved; and therefore, through the high-risk point isolationand closure device, unlocking and locking are easy to achieve, the operation process is simple and efficient, and the safety is high.

Description

technical field [0001] The invention relates to the technical field of production safety, in particular, to a high-risk point isolation and closure device. Background technique [0002] Industrial production installations, such as petrochemical installations, metallurgical installations, power installations, etc., have a large number of towers, kettles, boilers, manholes, valves, pipelines and other equipment and facilities; High-risk points such as high-risk points, borders, etc., especially during inspection and maintenance construction, there are more high-risk points such as restricted spaces. There are different toxic and harmful media in some confined spaces. If the management of entrances and exits such as manholes and flanges that people can enter is out of control, and people enter rashly, accidental injuries such as poisoning and suffocation will be caused; if the management of peripheral holes is out of control, it will Injuries such as falling from high places; ...
