Compared with the prior art, the utility model provides a drilling and blasting method ventilation car for construction tunnel the ventilation car can remove near excavation face, and can be used for the scattered cigarette of ventilation of a plurality of excavation faces simultaneously, and its ventilation effect is good, practices thrift engineering cost, and can avoid dismantling repeatedly and installing of fan in the hole for the construction progress.
Description
Technical Field
The utility model relates to a tunnel construction technology system especially relates to a bore ventilation truck for blasting method construction tunnel.
Background
When adopting the drilling and blasting method construction tunnel, the blasting can produce a large amount of dust and harmful gas, generally installs the ventilation blower additional in the hole or entrance to a cave at present, utilizes the tuber pipe to ventilate scattered cigarette to blasting excavation face.
The ventilation mode in the tunnel can be divided into a pressing type and an aspiration type. The forced ventilation ventilator is installed at the opening of the tunnel, and the suction ventilation ventilator is installed near the excavated tunnel face. When the press-in ventilation is adopted, the whole tunnel is filled with dust and harmful gas after ventilation, and the working environment in the tunnel is poor; when suction type ventilation is adopted, the fan cannot be installed close to a blasted tunnel face under the influence of blasting, so that the ventilation and smoke dissipation effects are poor, and in addition, the problem that the fan needs to be detached and then installed again along with the propulsion of the tunnel face exists.
Therefore, the ventilation vehicle for the tunnel constructed by the drilling and blasting method needs to be provided to solve the technical problems.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a portable to near boring of face explodes method construction ventilation car for tunnel improves ventilation effect.
The technical scheme of the utility model is that: the utility model provides a drilling and blasting method construction ventilation car for tunnel, including removing automobile body, fixed bolster, ventilation blower and linking tuber pipe, the ventilation blower passes through the fixed bolster can dismantle connect in remove on the automobile body, linking tuber pipe one end with the ventilation blower is connected, and the other end is connected with the interior tuber pipe of tunnel.
In the above scheme, the ventilator is movably arranged, installation is not needed, after the tunnel face is blasted, the ventilator moves to the optimal position near the tunnel face through the moving vehicle body, and the ventilator works close to the blasted tunnel face to improve the ventilation and smoke dissipation effects.
The movable vehicle body can adopt a common vehicle and also can adopt an intelligent control unmanned vehicle.
Preferably, the ventilator is an axial flow suction type ventilator.
Preferably, the mobile vehicle body is a truck, and the ventilator is arranged on a carriage of the truck.
Preferably, the connecting air pipe is a flexible air pipe.
Preferably, the diameter of the connecting air pipe is 700 mm.
Preferably, the fixed support is formed by welding steel bars with the diameter of 32 cm.
Compared with the prior art, the beneficial effects of the utility model are that:
the ventilation vehicle can move to the position near the excavation face, and can be used for ventilating and dispersing smoke of a plurality of excavation faces simultaneously, so that the ventilation effect is good, and the construction cost is saved;
secondly, the ventilation vehicle adopts similar suction type ventilation, and the air quality in the tunnel is good after ventilation and smoke dissipation;
thirdly, repeated dismounting and mounting of the fan in the hole can be avoided, and the construction progress is accelerated;
and fourthly, the ventilation vehicle is formed by simply processing and organizing conventional construction equipment, has a simple structure, is easy to assemble, and has small manufacturing difficulty.
Drawings
Fig. 1 is the utility model provides a drilling and blasting method ventilation vehicle for construction tunnel's structural schematic.
In the attached drawing, 1-a movable vehicle body, 2-a fixed support, 3-a ventilator and 4-a connecting air pipe.
Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments. It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict. For convenience of description, the words "upper", "lower", "left" and "right" used herein refer to the directions of the drawings, and do not limit the structure of the drawings.
As shown in fig. 1, the ventilation vehicle for a tunnel in drilling and blasting construction provided by the embodiment comprises a movable vehicle body 1, a fixed bracket 2, a ventilator 3 and a connecting air pipe 4.
The movable vehicle body 1 is an existing ordinary vehicle and can adopt a 3t diesel freight vehicle. The fixed support 2 is formed by welding steel bars with the diameter of 32cm, and is hinged in a carriage of the movable vehicle body 1 through bolts.
The ventilator 3 is an axial flow suction type ventilator, and is mounted on the fixing bracket 2 through screws. The axial flow suction type ventilator is a ventilator which forces gas to flow along the axial direction by the thrust action of the blades. When the prime mover drives the impeller to rotate in the casing, the certain installation angle between the shaft and the propeller blades produces thrust on the gas to push the gas to flow continuously along the shaft direction, so that the gas is sucked and exhausted continuously.
The connecting air pipe 4 is a flexible air pipe with the diameter of 700mm, one end of the connecting air pipe is connected with the ventilator 3, and the other end of the connecting air pipe is connected with an in-tunnel air pipe (not shown) of the tunnel.
After the tunnel face blasting construction, the ventilation vehicle is driven to the position near the construction face, the ventilator 3 is close to the blasting face, and the connecting air pipe 4 is connected with an in-tunnel air pipe used for ventilation in the tunnel. And (4) starting the ventilator to discharge the dirty air near the tunnel face to the outside of the tunnel through the air pipe in the tunnel, so as to realize the ventilation and smoke dissipation effects of the tunnel.
The above only is the embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent processes of the present invention are used in the specification and the attached drawings, or directly or indirectly applied to other related technical fields, and the same principle is included in the protection scope of the present invention.
