Description
Technical field
The present invention relates to coal mine fully-mechanized mining working excavation supports, more particularly, to coal mine crossheading temporary airtight excavation support.
Background technique
For highly gassy mine after coal working face back production, goaf side can have methane accumulation, especially mine
Return airway upper corner position, gathers before easily causing gas overpressure, coal working face is caused to stop production.Goaf watt in order to prevent
This pours in coal working face, needs to construct fire dam in fully-mechanized mining working crossheading to play the purpose of isolation goaf gas.Mesh
Before, constructing for fire dam takes artificial build to build sandbag or construct the mode of brick wall to complete more.But it is above-mentioned manually construct it is closed
The mode of wall needs to put into a large amount of human and material resources, and working efficiency is low, greatly reduces the fltting speed of coal working face.
Meanwhile personnel need the work at high methane accumulation in construction period, there is very big security risk.
Summary of the invention
It is an object of that present invention to provide a kind of coal mine crossheading temporary airtight excavation supports, and goaf is isolated for rapid sealing
Gas reduces goaf gas pouring in coal working face.
To achieve the above object, the present invention takes following technical proposals:
Coal mine crossheading temporary airtight excavation support of the present invention, including by pedestal, telescopic column, top beam and be connected to described
The alley hydraulic support ontology of link mechanism composition between pedestal and top beam；It is arranged in the alley hydraulic support rear body
There is temporary airtight device, the temporary airtight device includes the bottom bracket for being hinged on the base rear end, is set in the bottom bracket
It is equipped with the cabinet of upper opening structure, the left side that the upper and lower flexible top plate by power source drive is provided in the cabinet and is moved left and right
Side stretch vertical plate, right side stretch vertical plate；Correspond to the flexible vertical plate position of the flexible vertical plate in the left side and right side in cabinet left and right sidewall
Place is set, offers stretch the opening that vertical plate vertical sectional shape matches with stretch vertical plate and right side of left side respectively.
Power source is hydraulic cylinder or electric pushrod.
The rear portion of the bottom bracket is arranged in the flexible vertical plate in the left side, and vertical plate setting is stretched in the collet in the right side
The front of seat.
It is respectively set on flexible vertical plate left side in the flexible cover top surface, the flexible vertical plate right side in left side and right side
Flexible gasket or elastic seal ring.
Advantage of the present invention embodies in the following areas:
1, temporary airtight device and the alley hydraulic support ontology of front are articulated and connected, and transport after on the one hand splitting to underground
It is defeated, it on the other hand can adapt to the fluctuations on top by lane, bottom plate.
2, top plate, the flexible vertical plate in left side, the flexible vertical plate in right side are stretched when in use, it can be real according to the height and width in tunnel
Now freely stretch receipts.
3, solve the problems, such as it is existing manually beat that fire dam large labor intensity, consuming time is long, improve coal working face
Fltting speed.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Fig. 2 is the overlooking structure diagram of Fig. 1.
Use state diagram Fig. 3 of the invention.
Specific embodiment
As shown in Figure 1, 2, coal mine crossheading temporary airtight excavation support of the present invention, including by pedestal 1, telescopic column
2, the alley hydraulic support ontology of top beam 3 and the four-bar mechanism 4 being connected between pedestal 1 and top beam 3 composition；It is hydraulic in tunnel
Rack body rear portion is provided with temporary airtight device；Temporary airtight device includes the collet that 1 rear end of pedestal is hinged on by pin shaft
Seat 5 is provided with the cabinet 6 of upper opening structure in bottom bracket 5, the upper and lower flexible top driven by hydraulic cylinder is provided in cabinet 6
The flexible vertical plate 8 of plate 7 and the left side moved left and right, the flexible vertical plate 9 in right side；Correspond to the flexible vertical plate 8 in left side in 6 left and right sidewall of cabinet
It stretches at 9 position of vertical plate with right side, offers stretch vertical plate 8 with left side and right side is stretched 9 vertical sectional shape phase of vertical plate respectively
The opening matched.
The rear portion of bottom bracket 5 is arranged in the flexible vertical plate 8 in left side, and the flexible vertical plate 9 in right side is arranged in the front of bottom bracket 5, drives
The hydraulic cylinder 10 of dynamic flexible top plate 7 is arranged in that vertical plate 8 is stretched in left side and right side is stretched between vertical plate 9 vertically upward.
In order to improve sealing effect, in flexible 7 upper surface of top plate, the flexible vertical plate 9 in flexible 8 right side of vertical plate in left side and right side
Elastic sealing gasket is respectively arranged on left side.
As shown in figure 3, existing be illustrated by taking two framves, one group of excavation support as an example:
When work, temporary airtight device is transported to underground first, then by pin shaft by bottom bracket 5 and 1 rear end phase of pedestal
Hingedly.
When coal working face 11 needs closed goaf gas, two frame excavation supports are helped into 12 sides close to tunnel respectively
Flexible vertical plate 13,14 stretches out, then respectively stretching two frame excavation support sides adjacents in sealing contact with the tunnel nation 12 of respective side
Contracting vertical plate 15,16 relative extension are in sealing contact, finally respectively by the upward jack-up of the flexible top plate 17,18 of two frame excavation supports and lane
Road roof is in sealing contact, while cooperation is manually squeegeeed, the modes such as curtain realize being isolated for working face and goaf, to reach fast
Speed building temporary airtight wall purpose, plays the role of being completely closed goaf, is that a safety is created in the back production of coal working face
Space.
