Embodiment 1

[0044] Such as Figure 1 to Figure 8 As shown, the airbag-type pipeline isolator of the present invention includes an airbag 106, a pressure gas source 2 that supplies air to the airbag 106 through a pipeline, a linear drive mechanism and a plurality of movable supports 1017 that are all located inside the airbag 106, and the airbag 106 is a rotating body, and its two ends are telescopic end and fixed end respectively, and the driving direction of described driving mechanism is parallel with the axis of air bag 106, and it is fixed on the fixed end, and its driving end is connected with telescopic end, and described movable bracket 1017 includes the detection end movable bracket 103 and the isolation section movable bracket 107 which are sequentially hinged, and the ends of the detection end movable bracket 103 and the isolation section movable bracket 107 which are far away from each other are respectively hinged to the telescopic end and the fixed end.

[0045] A plurality o...

Embodiment 2

[0051] This embodiment is to illustrate the implementation of the drive mechanism.

[0052] The driving mechanism can adopt pneumatic rod, hydraulic rod screw mechanism and the like. The present invention specifically adopts the screw mandrel structure that can be directly manually driven, and the specific implementation is as follows:

[0053] Such as image 3 , Figure 4 as well as Figure 7 As shown, in the present invention, the drive mechanism includes a positioning tube 104 connected in sequence, a transmission gear sleeve 1014, and a hand wheel 1012 that drives the transmission gear sleeve 1014 to rotate around its own axis through a gear drive assembly. One end of the positioning tube 104 It is connected with the telescopic end, and its other end is inserted into the transmission gear sleeve 1014 and screwed therewith. The transmission gear sleeve 1014 is rotatably mounted on the fixed end, and the hand wheel 1012 is located outside the airbag 106 .

Embodiment 3

[0059] This embodiment is based on the above embodiments to further illustrate the implementation of the present invention.

[0060] Such as image 3 , Figure 4 as well as Figure 7 As shown, in the present invention, a fixing ring 1011 is installed on the side of the fixing end away from the inner cavity of the airbag 106 .

[0061] Located at the fixed end of the airbag-type pipeline isolator 1, when the pipeline used is a pipeline with a large inclination angle and a vertical state, the fixing ring 1011 is easy to fall or cannot be fixedly installed when the airbag-type pipeline isolator 1 is installed and disassembled fixed safety device. Specifically, an iron chain or a rope is connected to the fixing ring 1011, thereby connecting the airbag-type pipeline isolator 1 to one end of the iron chain or rope, and the other end of the iron chain or rope is connected to a fixable structure outside the pipeline, and then Keep the effective work of the airbag type pipeline iso...

Abstract

The invention relates to the technical field of maintenance, and particularly discloses an air bag type pipeline isolator. The air bag type pipeline isolator comprises an air bag, a pressure air source, a linear driving mechanism and a plurality of movable supports, wherein the pressure air source supplies air to the air bag through a pipeline, and the linear driving mechanism and the movable supports are all located in the air bag. The air bag is a rotating body, and two ends of the air bag are a telescopic end and a fixed end correspondingly. The driving direction of the driving mechanism isparallel to the axis of the air bag, the driving mechanism is fixed to the fixed end, and the driving end of the driving mechanism is connected with the telescopic end. Each movable support comprisesa detection end movable support and an isolation section movable support which are hinged to each other in sequence, wherein the ends, which are away from each other, of the detection end movable support and the isolation section movable support are hinged to the telescopic end and the fixed end correspondingly. According to the air bag type pipeline isolator, the air bag is attached to the innerwall of the pipeline, secondary isolation is formed in the pipeline, the durability and reliability of the isolation state can be kept, effective protection is provided for personnel when hazardous gas is suddenly increased, the personal safety of operators is improved, and relevant personnel can have sufficient time to safely evacuate.

Description

technical field [0001] The invention relates to the technical field of pipeline maintenance, in particular to an air bag type pipeline isolator. Background technique [0002] During the repair and maintenance of toxic and harmful gas pipelines or pipeline replacement, it is necessary to effectively isolate the pipeline and close the valves to ensure that maintenance personnel or operators are not harmed by toxic and harmful media. Poor communication between the valves leads to incorrect opening of the valve or failure to cut off the valve, resulting in accidents of personnel poisoning and injury. In particular, when the large diameter of the pipeline requires personnel to enter the interior of the pipeline for repair or equipment transformation, the danger factor to the internal workers increases exponentially, and external unsafe factors will affect the safety risks of the internal operators of the pipeline. When the wrong pipeline is transported with toxic and harmful med...
