Description
Technical field
The utility model relates to tunneling shield technical field of construction more particularly to a kind of city underground shield-tunneling construction electric locomotives
Sander.
Background technique
In tunneling shield work progress, when encountering phenomena such as road gradient in highway tunnel is larger, track is wet and slippery, locomotive traction process
In due to locomotive adhesion coefficient it is inadequate, often there is locomotive wheeslip and draw hypodynamic phenomenon, or even the things such as car slipping occur
Therefore.
Currently, most of locomotive sand spraying device is made of sanding valve, sandbox, sand pipe and pipeline.Sandbox is mounted on vehicle frame
On, a sanding valve is installed under sandbox, has a shared high-pressure air hose to equidirectional sanding valve in wheel, it is secondary when needing stucco
The pressure air of cylinder is directly entered sanding valve, blows dry fine sand and enters sand pipe, and sand is sprinkling upon on rail level by nozzle.
The sander sanding valve requires locomotive sand to be quartz sand, and granularity is suitable for, dry with good without clay and blocky impurity
Good mobility.Common good matter sand and two kinds of high-quality sand can be divided into for the sand that locomotive uses: common good matter sand is required containing quartz 70%
More than, clay component is no more than 3%；High-quality sand is required containing 90% or more quartz, and clay component is no more than 1%.Roughing sand must be after being sieved
It using, sand fineness is preferably advisable in 0.5 ~ 1mm or so, and it is most thin not to be preferably less than 0.2mm, it is most thick not to be preferably greater than 2mm.Moist sand
Son answers parch or spreads nature out and dries, and uses again until parching, with anti-clogging sand sprayer.
Since constructing metro tunnel site environment is moister, sand is easy agglomeration and can not flow to air port, existing simultaneously
Field does not also have the condition of drying sand, therefore, is unable to satisfy in tunneling shield work progress uses locomotive under real world conditions
The requirement of sand is also just unable to satisfy sand spraying apparatus stucco requirement substantially.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of cities that adaptation constructing tunnel electric locomotive stucco requires
The sander of city's subway shield tunnel construction electric locomotive.
To solve the above problems, a kind of sander of city underground shield-tunneling construction electric locomotive described in the utility model,
It is characterized by: the device includes and the stucco button phase in city underground shield-tunneling construction electric locomotive driver's cabin room on control panel
Air motor even and the sandbox being mounted in the city underground shield-tunneling construction electric locomotive frame；The top of the sandbox is equipped with
Axis hole, bottom are equipped with sand removing hole, and side is equipped with sand loading mouth, interior to be equipped with auger conveying axis；The output of the air motor
Axis is inserted into the axis hole and enters in the sandbox；The output shaft of the air motor is inserted into one end of the auger conveying axis
Inner hole, the other end are pierced by the sand removing hole；Pneumatic line in the air motor is connected with the stucco button；The dress
Sand mouth is equipped with buckle.
It is less than the sand grains of 2.5mm in the sandbox filled with partial size.
The air motor is linked together by screw II, plain cushion I, spring washer I and the sandbox.
The air motor is linked together by keyway and screw III, plain cushion II, spring washer II with the sandbox.
One end of the auger conveying axis is inserted into the output shaft inner hole of the air motor and is connected in by screw I
Together.
Compared with the prior art, the utility model has the following advantages:
1, the utility model is equipped with auger conveying axis in sandbox, drives auger conveying axis by air motor
Work, exports sand grains equably, efficiently solves because of sand in humidity big sander sand grains blocking in tunnel, sandbox
The problems such as grain is hardened, more adapts to the needs of current constructing tunnel electric locomotive stucco.
2, the utility model is of less demanding to locomotive sand, if granularity less than 2.5mm sand grains all can, for shield
Construction site mixing plant mixed sand can meet use, not have to programmed screening and drying.
Detailed description of the invention
Specific embodiment of the present utility model is described in further detail with reference to the accompanying drawing.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the sectional view of the utility model.
In figure: 1-air motor；2-sandboxes；3-auger conveying axis；4-screws I；5-screws II；6-plain cushions
Ⅰ；7-spring washers I；8-screws III；9-plain cushions II；10-spring washers II.
Specific embodiment
As shown in Figure 1 and 2, a kind of sander of city underground shield-tunneling construction electric locomotive, the device include and city underground
The air motor 1 and be mounted on city underground shield that stucco button in shield-tunneling construction electric locomotive driver's cabin room on control panel is connected
The sandbox 2 that structure is constructed in electric locomotive frame.
The top of sandbox 2 is equipped with axis hole, and bottom is equipped with sand removing hole, and side is equipped with sand loading mouth, interior defeated equipped with auger
Send axis 3；The output shaft insertion axis hole of air motor 1 enters in sandbox 2；Air motor 1 is inserted into one end of auger conveying axis 3
Output shaft inner hole, the other end is pierced by sand removing hole；Pneumatic line in air motor 1 is connected with stucco button；On sand loading mouth
Equipped with buckle.
Wherein: being less than the sand grains of 2.5mm in sandbox 2 filled with partial size.
Air motor 1 is linked together by screw II 5, plain cushion I 6, spring washer I 7 with sandbox 2.Screw II 5 is interior six
Angle roller screw M6x30.
Air motor 1 is linked together by keyway and screw III 8, plain cushion II 9, spring washer II 10 with sandbox 2.Screw
III 8 be hexagon socket head cap screw M8x25.
The output shaft inner hole of one end insertion air motor 1 of auger conveying axis 3 is simultaneously linked together by screw I 4.
Screw I 4 is hexagon socket head cap screw M6x6.
When work, sand grains first is filled in sandbox 2 from sand loading mouth, then fastens buckle；Last driver control stucco button,
Air motor 1 works.Under the action of compressed air, air motor 1 drives 2 inside spin of sandbox stirring conveying axis 3 to rotate, sandbox
Sand grains is uniformly exported through auger conveying axis 3 to rail level stucco in 2.
The utility model is of less demanding to locomotive sand, if granularity less than 2.5mm sand grains all can, shield is applied
Work Site station mixed sand can meet use, do not have to programmed screening and drying, efficiently solve because humidity is spread greatly in tunnel
The problems such as sand grains is hardened in the blocking of sand device sand grains, sandbox.
