Abstract
The utility model provides a kind of underground and hangs air duct stent temporarily, it is characterized in that, including tripod, supporting rod and air duct retaining frame, gear hoistable platform is set at the top of the tripod, guide pipe is installed on the gear hoistable platform, the guide pipe and supporting rod nested encryptions, welded sleeve in the air duct retaining frame, the sleeve are connected with supporting rod.The lifting of the easily controllable air duct of air duct stent is hung in the underground of the utility model temporarily, reduces the intensity of manually lifting air duct, reduces the secondary destruction of air duct caused by situations such as air duct lands suddenly when manually lifting air duct.
Description
Technical field
The utility model is related to a kind of underground coal mine article pylons more particularly to a kind of underground to hang air duct branch temporarily
Frame.
Background technology
At present, driving face in coal mine air duct is repaired because of whitewashing into lane operation or because air duct interface is damaged when work, by
It is larger in current air duct quality, when having hung air duct landing, it is easy to be collapsed in interface and convince cause by patient analysis and leak out, peace is brought to working face
Full hidden danger.During long working of whitewashing, because air duct locally lands, air duct local resistance is caused to increase, driving face wind
Amount is reduced, and brings security risk.Most air duct stent is to be used for hanging air duct using supporting rack and other items in the prior art,
Due to gravity, air duct is easily deformable in support, and so as to increase air duct resistance, there are security risks.
Utility model content
In order to solve problem above, the utility model proposes a kind of undergrounds to hang air duct stent temporarily, which is characterized in that
Including tripod, supporting rod and air duct retaining frame, gear hoistable platform is set, on the gear hoistable platform at the top of the tripod
Guide pipe is installed, the guide pipe and supporting rod nested encryptions, welded sleeve, the sleeve and supporting rod in the air duct retaining frame
Connection.
Further, the air duct retaining frame is hingedly formed by three sections of 120 ° of circular arc iron pipes.
Further, it is both provided with safe pin hole on the supporting rod and guide pipe.
Further, gear lifting gear is installed on the gear hoistable platform.
The lifting of the easily controllable air duct of air duct stent is hung in underground provided by the utility model temporarily, reduces manually lifting wind
The intensity of cylinder.
Description of the drawings
Fig. 1 is the structure diagram that air duct stent is hung in a kind of underground of the utility model temporarily；
Fig. 2 is partial view A in Fig. 1；
Fig. 3 is the sectional view of gear lifting gear.
In figure：1- tripods, 2- supporting rods, 3- air ducts retaining frame, 4- sleeves, 5- guide pipes, the safe pin holes of 6-, 7- gear liters
Platform, 8- joysticks, 9- gears mounting groove, 10- gears drop.
Specific embodiment
The specific embodiment for hanging air duct stent temporarily to a kind of underground of the utility model below in conjunction with the accompanying drawings carries out in detail
Describe in detail it is bright, the embodiment be merely to illustrate the utility model rather than limitation the scope of the utility model, people in the art
Member falls within the application scope as defined in the appended claims to the modification of the various equivalent forms of the utility model.
As shown in Figure 1, air duct stent is hung in a kind of underground temporarily, including tripod 1 and air duct retaining frame 3, welded on tripod 1
Gear hoistable platform 7 is connect, guide pipe 5 and gear lifting gear, such as Fig. 2, gear lifting gear bag are welded on gear hoistable platform 7
Joystick 8, gear mounting groove 9 and gear 10 are included, closely guide pipe 5 is welded on gear hoistable platform 7 gear mounting groove 9, tooth
It takes turns mounting groove 9 and selects the higher steel plate of intensity, joystick 8 is fixedly connected with gear 10, and joystick 8, gear 10 and gear are installed
Slot 9 is articulated and connected, and 8 rotation driven gear 10 of joystick rotates, such as Fig. 3, and gear 10 drives supporting rod 2 to move up and down, guide pipe 5
The a upper nested energy toothed supporting rod 2 of height up and down, supporting rod 2 are made of hollow thread steel, can more support air duct
Safe pin hole 6 is all left on weight, supporting rod 2 and guide pipe 5, when air duct retaining frame 3 is promoted certain height by gear lifting gear
It when spending, glides in order to prevent, safety pin is inserted into the safe pin hole 6 between supporting rod 2 and guide pipe 5, ensures air duct retaining frame 3
In the stability of certain altitude, prevent from gliding suddenly, air duct is made to drop.
Air duct retaining frame 3 is made of three sections of 120 ° of circular arc iron pipes or stainless steel tube, prevents from getting rusty, and influence stent uses the longevity
It orders, is articulated and connected between each iron leg pipe, energy flexible rotating in actual use, can be according to the big minor adjustment wind of air duct diameter
The diameter of cylinder retaining frame 3, and be easily assembled to dismantle and carry, welded sleeve 4 in air duct retaining frame 3, for being connected with supporting rod 2,
When without using the stent in the case of underground coal mine narrow space, it is readily disassembled and carries.
When the utility model is used, air duct is placed in two air duct retaining frames 3, using gear lifting gear by air duct
Retaining frame 3 rises to the height of needs, and safety pin is inserted on the safe pin hole 6 between supporting rod 2 and guide pipe 5, ensures the branch
The stability of frame, and prevent air duct retaining frame 3 downslide air duct is caused to land, when air duct when not in use, utilize gear lifting gear will
Air duct retaining frame 3 drops to certain height, removes air duct, and air duct retaining frame 3 from tripod 1 is removed, is easy to carry about with one.
The lifting of the easily controllable air duct of air duct stent is hung in the underground of the utility model temporarily, reduces and manually lifts by crane air duct
Intensity reduces the secondary destruction of air duct caused by situations such as air duct lands suddenly when manually lifting air duct.
The preferred embodiment of the utility model, still, the utility model and unlimited are described in detail above in association with attached drawing
Detail in the above embodiment, can be to the skill of the utility model in the range of the technology design of the utility model
Art scheme carries out a variety of simple variants, these simple variants belong to the scope of protection of the utility model.
