Description
Technical field
The invention belongs to railway engineering machinery fields, and in particular to a kind of railway dust-arrest device.
Background technique
When rail track cleaning, route need to be blocked, operation is carried out in Window time, therefore, not only to complete ballast aggregate
Cleaning work, it is necessary to which route is restored to working condition.
A large amount of fugitive dusts can be generated during railway line overhaul sorting operation, operating personnel does not see rail level the most of the time
Concrete condition can all make a big impact sometimes even in blind mode of operation to the precision of sorting operation, to whole
A maintenance Window time causes biggish loss.Meanwhile a large amount of fugitive dusts generated when sorting operation can also be to operating personnel and week
The health of side resident threatens, and pollutes environment.
Nowadays, part track division is also only using municipal sprinkler dust suppression before sorting operation, and this mode is in iron
Route road is inconvenient, and anti-dust effect is very little, extremely undesirable.It takes a broad view both at home and abroad, at present without dedicated railway
It therefore needs to design a kind of railway dust-arrest device with dust-arrest device, carries out sprinkler operation to route before construction, play suppression
Dirt effect, improves operating environment, reduces environmental pollution, and improves sorting operation efficiency.
Summary of the invention
It is an object of the invention to solve at present both at home and abroad without dedicated railway dust-arrest device, so that carrying out railway
The problem of ambient enviroment is polluted when major repair of track sorting operation, provides a kind of railway dust-arrest device.
To achieve the above object, technical solution provided by the present invention is:
A kind of railway dust-arrest device, is characterized in that, including braced frame, tank body and operation room；
The braced frame include two rectangular end frames and by two rectangular end frame corresponding vertexs connect two upper beams
With two underbeams；Wherein, two underbeams use I-steel；The tank body and operation room are respectively positioned in braced frame, and along support
Lengths of frame direction is arranged side by side, and is separated using intermediate box；The intermediate box is arranged in parallel with two rectangular end frames, packet
Include intermediate upper beam, intermediate lower beam and two auxiliary struts；Wherein, intermediate lower beam uses I-steel；
The both ends of the tank body are fixedly mounted on intermediate box and one of rectangular end frame by skirt；Support bearing
Power is uniform, which can open up discharge opening, prevents ponding；
Water unit, watering unit, control unit and power supply unit are provided in the operation room；
The upper water unit and watering unit are respectively used to carry out upper water and watering to tank body；
Described control unit is for controlling water unit and watering cell operation；
Said supply unit is used for control unit, upper water unit and watering unit power supply.
Further, each vertex of each rectangular end frame is welded with container special corner, for shipping and lifting by crane
Device；The special corner directly matches fixation with the lock on flatcar, and connection is reliable, does not need to bundle and reinforce, can satisfy
Container Transport condition；
Each rectangular end frame between upper beam and underbeam, between two frames that each rectangular end frame is adjacent, operation room side
It is provided with diagonal brace between auxiliary strut and upper beam and underbeam, between auxiliary strut and intermediate upper beam and intermediate lower beam, it can
Further strengthen the strength and stiffness of braced frame；
It is welded with backplate on the outside of the auxiliary strut, for increasing the volume of half tank body；Since intermediate box is located at branch
In support frame frame, therefore the rectangular end frame overall dimensions of braced frame are big compared with intermediate box size, in design, in order to will entirely half
The volume of tank body is accomplished to maximize, be rationalized, and the radial dimension by half tank body can be selected to accomplish water compatible with rectangular end frame
Standard, if so, one end that half tank body is connect with intermediate box will stretch out auxiliary strut, so, in auxiliary strut
One piece of backplate is welded in outside, is welded convenient for half tank body, while also functioning to support and protecting the effect of half tank body.
During fabrication, the container framework of standard can be used in entire braced frame, but in order to meet actual demand, need to will prop up
Support frame frame divides region, the equipment for installing different function, for example is divided into two, and side is for installing half tank body, the other side
For operation room.Therefore consider from the load-bearing capacity of entire container framework, need to increase intermediate box in braced frame (intermediate
Upper beam, intermediate lower beam and two auxiliary struts), half tank body is mounted on braced frame rectangular end frame in by skirt
Between on box；Meanwhile the dual consideration of the weight and its load-bearing based on half tank body itself, underbeam and intermediate lower beam are all made of
I-steel can effectively improve the rigidity and load-bearing capacity of frame, power is passed because the longitudinal stress of I-steel is preferable, rigidity is big
It is handed in the special corner of quadrangle.Whole device it is compact-sized, multiple functional, independence is strong, transport, connection with lifting nor
It is often convenient；And entire dust-arrest device is self-powered, is not limited by extraneous power supply, sprinkler operation it is adaptable.
Further, the tank body includes cylinder and the end socket for being encapsulated in cylinder both ends, generally round tank body, wherein
Cylinder is formed by shell ring welding, and two end sockets are the ellipse head of whole cold moudling；The tank of traditional railway tank car is used for reference
Body structure relies on tank car many years successful design experience, comprehensively considers media compatibility, processing and welding technological properties, passes through
The advantages that factors such as Ji property have bearing capacity strong, and structure is mature, and difficulty of processing is low, reduce cost.Using tank hydraulic pressure test
Guarantee tank body quality with non-destructive testing technology.Certainly, which can also be other shapes than a circular one, such as rectangular tank
Body, design cost is larger, processing technology is more difficult, and operability is not strong.
Manhole and at least one air inlet are offered above the cylinder；Manhole facilitates maintenance personal to pass in and out tank body,
Air inlet then can effectively ensure that outside air enters in tank body, guarantee work when tank body inside and outside pressure equilibrium, the air inlet
The setting of hole mouth down, flying bird, sundries etc. can be prevented to be strayed into air inlet, aperture is blocked, influence the normal use of device；
Bottom in the cylinder close to operation room is provided with liquid trap, makes liquid trap that the lowest part of cylinder be arranged in as far as possible
Residual liquid, can effectively be gathered in liquid trap, be conducive to the intracorporal liquid of drain tank by position；
