Abstract
The utility model is to a hopper car without cover, especially for transporting bulk goods, such as coals. The essence is that the manual speed change mechanism in the upper transmission device is an enclosed independent worm-wheel worm reducer; the right jaw clutch of the shaft end is clutched with the upper driving shaft; while the left and middle jaw clutches embedded in the upper driving shaft drive the double shifting forks through a clutch handle to realize pneumatic operation and manual operation. Consequently the utility model has the advantages of stable and reliable operating performance and small force moment of opening and closing the door in manual operation, and can realize entire column unload, grouping unload and single car unload.
Description
The utility model belongs to rolling stock and makes the field.
Prior art in the utility model prior art field is: the model of Sifang Rolling stock Inst. Ministry of Railway's development is a K18D moulded coal charcoal hopper car, this car adopts top locking-type switching mechanism, make locking performance and shutter door moment that improvement be arranged greatly, but the problem that exists is: the top transmission of this car switching mechanism is manually at closing time, speed reduction gearing (worm and gear) is an open type, it is very inconvenient that maintenance and service adjustment are installed, simultaneously in the transmission device of top, during with the hand switch bottom door, the two way cylinder that drive when pneumatic moves together.Therefore, cause the torque ratio of hand switch door bigger.
Design goal of the present utility model is: at the weak point of above-mentioned existence, design independently worm reducer and when pneumatic, manual and manual of a kind of osed top, the coal hopper car that moment is little.
Design plan of the present utility model is: a kind of coal hopper car of being made up of car body, top transmission device and bottom transmission device, its essence is: (1) Outboard Sections of two ends headwall on the car body side wall, do not influencing integrated carrying, do not weakening under the situation of side wall intensity, two trapezoidal holes have been increased, to alleviate the deadweight of car body; The crossing place, right angle of inboard side wall and headwall installs the garden arc plate that radian is ∝ additional at the car body two ends, makes car no longer amass coals for interior four jiaos.In order to eliminate in the car the long-pending coal on the laterally back and funnel back (laterally back and vertical back) top, in this car laterally the inner arc of back and vertical back be R6～R10; Install fan-shaped spillplate additional at the two ends of car body bottom door, and strengthen with stiffening angle.Make that coal no longer flows to lock body, makes locking more reliable when opening the door, in order to avoid amass the problem of coal except labor cleaning's lock body.(2) worm reduction box in the transmission device of top is independently parts of osed top, and by its axle head (right side) denture clutch and the clutch mutually of top transmission shaft, (right side) denture clutch is two pawl power-transfer clutchs, hand gear mechanism has not only made things convenient for installation, maintenance and adjustment like this, also improved simultaneously driving efficiency, make drive disk assembly be able to good lubrication, prolonged service life, and reduced manual-lock moment.(3) at bearing support (22) and bearing support 1(18) between the top transmission shaft on and bearing support 1(18) right-hand member the overhead cover of top transmission shaft one three-jaw gear, one (left side) denture clutch that is nested, shackle and (in) denture clutch, the three-jaw wheel and rack is meshed, drive tooth bar and the driven gear motion by two way cylinder, (left side) denture clutch is a three-jaw power-transfer clutch foundry goods, be with spring at neck, the trip ring that the fixedly employing of spring right-hand member has a screw thread spins with (left side) denture clutch neck end and forms; Be shaped on spring box draw-in groove and two fork draw-in groove on the shackle, its spring box draw-in groove links by spring box (20) spring (21) and (left side) denture clutch.(left side) denture clutch and shackle are become one.And be embedded on the top transmission shaft of bearing support 1 right-hand member (in) denture clutch is two pawl power-transfer clutchs, its neck is shaped on two fork draw-in grooves, two fork draw-in grooves by the two fork draw-in grooves on two forks and the shackle mutually clamping realize its (left side, in) denture clutch and three-jaw gear, the clutch of (right side) denture clutch phase, fixing of two forks realized by two fork seats.When pneumatic, (left side) denture clutch engages with the empty three-jaw that is enclosed within the three-jaw gear on the transmission shaft of top, driven gear and (left side) denture clutch and top transmission shaft rotate synchronously by two way cylinder driving tooth bar, drive the purpose of top lock switching mechanism switching bottom door to realize it; In the time of manually, (left side) denture clutch is enclosed within being out of gear on the transmission shaft of top with sky, (in) denture clutch then is meshed with (right side) denture clutch, the gear that making has leisure is enclosed within on the transmission shaft of top dallies on axle, do not seesaw and do not drive two way cylinder, thus with make by rotation hand wheel intermeshing retarder axle head (right side) denture clutch and (in) denture clutch rotates synchronously with the top transmission shaft.Like this, realized that not only manual drive top lock switching mechanism opens and closes the purpose of bottom door, alleviated the shutter door moment when manual simultaneously greatly, thereby realized design goal of the present utility model.Pneumatic and manually operated is changed, and then moves forward and backward by the two forks of clutch handle drive and realizes.The pawl of three-jaw gear and (left side) denture clutch is the five equilibrium three-jaw.(4) be embedded with slide key on the top transmission shaft between bearing support and the bearing support 1 and on the top transmission shaft of the right-hand member of bearing support 1, and on the inwall of (left side, in) denture clutch, be milled with sliding keyway.Therefore, it is joining by keyway and the slide key on the transmission shaft of top in (left side, in) denture clutch and the shackle being embedded in (left side, in) denture clutch on the transmission shaft of top and shackle.(left side, in) denture clutch and shackle can move forward and backward along its slide key.
