In order to achieve the above technical effect, the utility model discloses a technical scheme is: the utility model provides a portable trunk line maintenance mechanism, includes the trunk line, open the side of trunk line has the horizontally access hole, be equipped with fire-retardant pad in the access hole, its outside is equipped with vertical apron, the inboard of apron is the cambered surface, and hinge and access hole's top swing joint is passed through at its top, under the natural state, the apron is flagging, pastes with the access hole mutually and leans on.
Preferably, the main pipeline is connected with two branch pipelines.
Preferably, the access opening is rectangular.
Preferably, the flame-retardant pad is in a frame shape and is fixed in the access hole through glue. The frame-shaped flame-retardant pad is fixed with the access hole at the outer side, and the inner side can be attached to the cambered surface of the cover plate, so that the sealing performance of the access hole is improved.
Preferably, the cover plate is made of a stainless steel plate, and the cover plate can cover the access hole. The cover plate made of the stainless steel plate has high strength and long service life.
Preferably, the number of the hinges is two, and the two hinges are respectively arranged on two sides of the access hole. Two hinges can make the atress more even when the apron overturns, still can alleviate self bearing pressure, increase of service life.
Preferably, two sides of the hinge are respectively connected with the main pipeline and the cover plate through screws. In order to fix the two sides of the hinge with the main pipeline and the cover plate respectively.
Preferably, the screw is a self-tapping screw. When the tapping screw is used, a tooth hole does not need to be tapped on the main pipeline, and the installation is more convenient.

Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
As shown in FIGS. 1-3, a portable trunk line maintenance mechanism, including trunk line 1, open the side of trunk line 1 has horizontally access hole 101, is equipped with fire-retardant pad 2 in the access hole 101, and its outside is equipped with vertical apron 3, and the inboard of apron 3 is the cambered surface, and hinge 4 and access hole 101's top swing joint is passed through at its top, and under the natural state, apron 3 is flagging, pastes with access hole 101 mutually and leans on.
Two branch pipelines 5 are connected to the main pipeline 1.
The access opening 101 is rectangular.
The flame-retardant pad 2 is frame-shaped, and the flame-retardant pad 2 is fixed in the access hole 101 through glue. The outer side of the frame-shaped flame-retardant pad 2 is fixed with the access hole 101, and the inner side of the frame-shaped flame-retardant pad can be attached to the cambered surface of the cover plate 3, so that the sealing performance of the access hole 101 is improved.
The cover plate 3 is made of a stainless steel plate, and the cover plate 3 may cover the service opening 101. The cover plate 3 made of the stainless steel plate has high strength and long service life.
The number of the hinges 4 is two, and the two hinges 4 are respectively arranged on two sides of the access hole 101. Two hinges 4 can make the atress more even when apron 3 overturns, still can alleviate self bearing pressure, increase of service life.
Two sides of the hinge 4 are respectively connected with the main pipeline 1 and the cover plate 3 by screws 6. In order to fix the two sides of the hinge 4 with the main pipeline 1 and the cover plate 3 respectively.
The screw 6 is a self-tapping screw. When the self-tapping screw is used, a tooth hole does not need to be tapped on the main pipeline 1, and the installation is more convenient.
The working principle is as follows: during the use, because access hole 101 is opened in the side of trunk line 1, not only overhaul convenient like this, apron 3 is under the effect of self gravity moreover, and the flagging is hugged closely access hole 101 naturally. When the waste gas treatment system operates, a fan (not shown in the figure) in the system is started, the cover plate 3 is adsorbed on the access hole 101 under the action of negative pressure of the fan, and the cambered surface design on the inner side of the cover plate 3 can be tightly attached to the flame-retardant pad 2, so that the sealing performance of the cover plate 3 and the access hole 101 is ensured. Thus, the cover plate 3 and the access opening 101 can be sealed and fixed without using a mechanical method. When needing to overhaul, stop the fan operation, lose the negative pressure in the trunk line 1 after, the maintainer with apron 3 around hinge 4 upwards upset, can open access hole 101, get into from trunk line 1 side, need not to climb the operation, it is more convenient, safety to operate.
The present invention is not limited to the above specific embodiments, and for those skilled in the art, the above conception can be used without any creative work, and all the changes made fall within the protection scope of the present invention.
