Description
Technical field
The present invention relates to railway hopper cars, especially with it is a kind of can independent control hopper wagon often fan opening and closing and the energy of bottom door
Realize that unilateral or two side dumping clean cargo objects easing gears are related.
Background technology
Hopper wagon is laborsaving, energy saving, economical quick by the unloading of cargo gravity, but domestic hopper wagon vehicle is less, unloading knot
Structure, form are also more single, and the width for the infrastructure that cannot especially be unloaded according to melt pit, transmission belt etc. is unloaded to adjust vehicle
Width.Such as KZ70 type stone tiny fragments of stone, coal, etc. hopper wagons, it is opened and closed simultaneously using the unilateral whole bottom doors of the retarder control with handwheel, KM70 moulded coal charcoals
Hopper wagon controls all bottom doors using a retarder with handwheel and is opened and closed simultaneously, this transmission using the retarder with handwheel
Device is not suitable for arrangement and covers retarder more because retarder weight is big, volume is big, handwheel rotating cycle is more, operating space is big
The independent opening and closing of multiple bottom doors is controlled, otherwise light weight increases, and operation occupied space is big, cargo carrying capacity reduces so that vehicle
Indices decline.Using gear, rack pulling-tray type bottom door easing gear, a vehicle can be arranged more L70 type foodstuff hopper wagons
The easing gear is covered, a fan bottom door can be individually opened, adapt to the width of all kinds of unloading equipments, under which must be arranged funnel just
Side, bottom door can only be operated one by one under vehicle, be unable to centralized operation, it is inconvenient for use, and the device can only vehicle just under
Clean cargo object unloads in side, cannot unilateral or two side dumping clean cargo objects.
Invention content
The present invention provides a kind of automobile-used rail mounted list fan bottom door independent control easing gear of railroad hopper, above-mentioned existing to solve
Some deficiencies, can independent control hopper wagon often fan the opening and closing of bottom door and can realize unilateral or two side dumping clean cargo objects unloadings, collection
Middle operation adapts to the unloading equipment of different unloading width.
In order to achieve the object of the present invention, intend using following technology：
A kind of automobile-used rail mounted list fan bottom door independent control easing gear of railroad hopper, is arranged below hopper wagon bell mouth
Unilateral side or both sides, can unilateral side unload clean cargo object or two side dumping clean cargo objects, which is characterized in that including bottom door opening and closing handle, track, branch
Point seat, crank throw, gag lever post, transmission shaft, pull rod, band idler wheel bottom door, pedestal, bottom door opening and closing handle is by floor installation in car body steel
On the chassis of structure, bottom door opening and closing handle connects transmission shaft, and transmission shaft passes through fulcrum block, fulcrum block to be fixed on steel structure of car body
On supporting clapboard alien invasion, crank throw is fixed on transmission shaft, gag lever post one end is rotatably coupled on fulcrum block, and the other end is used
Round pin is connect with pull rod, and the round pin is through in the strip hole of crank throw, limits the movement locus of pull rod；Pull rod with idler wheel bottom door
Connection, band idler wheel bottom door connection are located in orbit, and track welding is in the big plane of supporting clapboard of steel structure of car body.Manipulator
Handle concentrated setting is in vehicle one end, and after opening locking handle apparatus, rotation bottom door opening and closing handle passes through transmission shaft, crank throw and pull rod
It draws and the bottom door with idler wheel is pushed to move in orbit, realize the open and close of bottom door.
Further include locking handle apparatus according to above-mentioned design, locking handle apparatus is mounted on the base.Locking handle apparatus
Including handlebar and supporting rod, handlebar lower part has strip through-hole, support bar top to be through strip through-hole by round pin and pin cap
It is interior, there is bar shaped unlocking through-hole in the middle part of handlebar, bar shaped unlocking through-hole bottom side is jagged, there is lock pin, locking on bottom door opening and closing handle
The handlebar of handle apparatus can be buckled in by bar shaped unlocking through-hole jaggy on the lock pin of bottom door opening and closing handle.The height of lock pin
Less than support bar top height.After bottom door completely closes, it is closed locking handle apparatus, bottom door opening and closing handle can be prevented in vehicle
Driving process is opened accidentally.
According to above-mentioned design, the bottom door opening and closing handle is additionally provided with ratchet with transmission shaft connection place, and ratchet sleeve is in transmission shaft
On, bottom door opening and closing handle be equipped with the matched pawl of ratchet, prevent enabling back handle accidental counter rotation close the door.
According to above-mentioned design, described device is installed on vehicle bell mouth bottom, can be installed along longitudinal direction of car center line both sides
One or more sets, unilateral side installation unilateral can be unloaded, and both sides or unilateral unloading can be achieved in both sides installation, and every section of longitudinal direction of car direction is all
Open a fan bottom door, detachable net interior cargo.
According to the above configuration, when the installation of vehicle side, which covers the device, using the hollow steel pipe of different tube diameters as each
The transmission shaft of covering device, Guan Guanxiang are worn, non-interference, the bottom door of each covering device by respective bottom door opening and closing handle independent control,
Appropriate number of bottom door unloading can be independently opened according to the size of unloading equipment.It, can root with the hopper wagon of the easing gear
The quantity of the easing gear, the length and width size of bottom door are rationally designed according to the requirement of vehicle parameter, unloading equipment, makes funnel
Vehicle adapts to all kinds of unloading equipments such as a variety of melt pits of different sizes, conveyer belt.If unloading equipment width only meets a bottom door
After unsnatching the corresponding leakage storehouse cargo of a bottom door, vehicle is advanced certain distance then after opening a fan bottom door for unloading, unlatching
Another fan bottom door is unloaded, reciprocal aforesaid operations until in vehicle funnel all cargos unload only.
The beneficial effects of the invention are as follows：
1, the hopper wagon of rail mounted list fan bottom door independent control easing gear is configured, each bottom door can be controlled individually, be grasped
Vehicle one end is concentrated on as handle capable of being, the outer unilateral or two side dumping clean cargo objects of energy track adapt to different size of unloading equipment.It should
Device is easy to use, to the adaptable of vehicle and unloading equipment；
2, the device is by rotating 0 °~100 ° of bottom door opening and closing handle, after manpower is amplified by transmission shaft, crank throw, connecting rod
Reach bottom door, the idler wheel on bottom door made to roll in orbit, realize bottom door open 0mm~360mm aperture, band idler wheel bottom door with
Track is rolling friction, and frictional resistance is small, is opened convenient for bottom door, and bottom door opening speed is very fast；
3, bottom door opening and closing handle is equipped with pawl, ratchet anti-rotation device, prevents bottom door opening and closing handle in door opening process from inverting；
4, the device manipulation unit only have handle and safety locking device, it is simple in structure, small, can install concentratedly in
Vehicle one end, easy to operation, maintenance；And device is all made of fastener and is attached, it is easy to disassemble；
5, the utilization on railway freight hopper wagon can realize that single fan bottom door independently is opened and closed, can realize hopper wagon unilateral side or
The function of two side dumping clean cargo objects, adapts to different size of unloading equipment, and unloading equipment adaptive faculty is strong.
