Description
Technical field
The present invention relates to a kind of transportation device, particularly one is with emptying equipment superimposed trailer.
Background technology
The applicant once applied for a little earlier time " a kind of bulk goods formula superimposed trailer compound emptying equipment ", two driving chains that its driving wheel is connected with flower wheel both sides, the supporting plate evenly arranged above two driving chains, be arranged in parallel below supporting plate some backing rolls that freely can rotate along driving chain direct of travel, utilize backing roll to lift and drive supporting plate to advance, thus realize goods unloading, but this structure remains in certain defect: owing to needing anvil roll for lifting flexible supporting plate, thus anvil roll needs the quantity of setting more, otherwise the supporting plate of flexibility will subside under the Action of Gravity Field of goods, cause cargoes from scattering, and the anvil roll arranging larger amt is unfavorable economically.Although the advancing of supporting plate that can lift along with it of each anvil roll and freely rotating in addition, the rotation friction of single anvil roll may be little, but at One's name is legion, when the pressure at full capacity of bearing goods is very large, overall friction power can not be despised, to chain be caused can not rotate when the tractive force that HM Hydraulic Motor provides is not enough to offset this overall friction power thus the unloading of goods cannot be realized, otherwise need to provide more high-performance HM Hydraulic Motor, this can cause the high of cost equally, driving chain also needs to bear larger tension force on the other hand, to the specification of driving chain, performance requriements also can improve.
This patent application is in order to reach the object of fully unloading, also inside car side board, be respectively equipped with portable plate, outside the curve of portable plate and car side board, formed between cabin floor and along compartment, longitudinally several load lifting cylinder is set along in the lifting space of compartment longitudinal direction, the junction of load lifting cylinder one end and railroad car lateral wall and diapire is affixed, the other end and curve affixed, obvious load lifting cylinder will occupy certain space, but piston of load lifting cylinder bar can not be greater than cylinder body length in the extreme length of ideally stretching out, in order to realize the rotation of portable plate, the curvature of the curve of portable plate must be needed larger, for load lifting cylinder provides larger extendable room, needs are compressed effective cargo capacity by this, this is that semitrailer compartment manufacturing enterprise or semitrailer compartment user are unacceptable.
Summary of the invention
Object of the present invention is just the deficiency for the previous patent of applicant, provides a kind of Novel self-unloading superimposed trailer.
For realizing this object, technical scheme provided by the invention is:
This self-discharging semitrailer, comprise vehicle frame 1, be arranged on the compartment 2 on vehicle frame 1 and emptying equipment 3, this emptying equipment 3 comprises the driven sprocket 31 and drive sprocket 32 that are installed on vehicle frame 1 rear and front end, the HM Hydraulic Motor 30 be connected with drive sprocket 32, two driving chains 33 around the home on driven sprocket 31 and drive sprocket 32, unlike the prior art: the pin link plate of described driving chain 33 is divided into two kinds: one is conventional pin link plate 333 ', one is special-shaped pin link plate 333, between two special-shaped pin link plates 333, more than one conventional pin link plate 333 ' is set, the circumferential cylindrical of the roller 331 of chain 33 protrudes from the upper lower edge of inner plate 332 or conventional pin link plate 333 ', abnormity pin link plate 333 is with the plate ear 3331 of outerplanar higher than the circumferential cylindrical of roller 331, plate ear 3331 is fixed supporting plate 34, supporting plate 34 is fixed rubber belt track 35, be fixed on two guide rail 36 support rollers 331 on vehicle frame 1.Compared with prior art, the present invention has abandoned anvil roll, simplifies the structure, and reduces cost.
Further, one end of any one rubber belt track is fixed by screws on the supporting plate corresponding with it, its free end crosses that supporting plate that be adjacent, that deviate from direct of travel when advancing to above driving chain, take put be separated by with it, on that supporting plate of deviating from direct of travel.Adopt this structure, the part of emptying equipment and cargo contacts has the rubber belt track of 2 layers and even 3 layers, goods can not be scattered and collapsed by pressure in gap between supporting plate, friction coefficient simultaneously between 2 layers of rubber belt track is less than the friction coefficient between rubber belt track and goods, thus unloading of drawing goods easier than the rubber belt track of individual layer.
Further, the length of described supporting plate 34 overlaps to line of centers with the line of centres of corresponding two plate ears 3331 on two driving chains 33.Adopt this technical scheme, the gravity that goods is delivered on chain is relatively more even, makes whole device lifetime longer, runs more steady.
Further, the length L of described supporting plate 34 is 60-100cm, and width W is 1-15cm, interval 0-50cm between adjacent two supporting plates 34.
As preferred further, the length L of supporting plate 34 is 85-91cm, and width W is 6-7cm, is spaced apart 10-20cm between adjacent two supporting plates 34.The length of supporting plate determines the interval of the unloading of goods, and length is oversize, and the propulsive effort needed is too large, and length too little then unloading efficiency is too low.The too little then cost of width of supporting plate is too high, and width is too large then comparatively large in chain turning amount of deflection, not only make supporting plate easily be out of shape, and unloading resistance is larger.The present invention just obtains this moderate and preferably technical scheme by test of many times.
Further, described supporting plate 34 arranges the reinforced rib 341 of more than 1 in the side of driving chain 33, along length to direction.Adopt this technical scheme just in order to avoid supporting plate in chain turning amount of deflection compared with the yielding problem of great Rong.
Further, this self-discharging semitrailer also comprises two group oil cylinders 4, described compartment 2 comprises front apron 22, rear on turn over that to open door (attached not shown, as follows) and the movable gusset 21 of L shape of two specular in left and right, the movable gusset 21 of described L shape comprises mobile side board 211 and the removable bottom 212 with mobile side board 211 consolidation, free end and the vehicle frame 1 of removable bottom 212 are hinged, one end and the vehicle frame 1 of oil cylinder 4 are hinged, the other end and removable bottom 212 hinged.
Particularly, front apron 22 and rear on turn over open respectively with vehicle frame 1 consolidation and with the movable gusset 21 of L shape manually or forced locking device match.
Further, the compartment 2 of this self-discharging semitrailer also comprises fixed side 23, and fixed side 23 is positioned at outside mobile side board 211, respectively with vehicle frame 1, front apron 22 consolidation, with rear on turn over open door manually or forced locking device match.
Adopt technique scheme, the left and right two parts in compartment can be distinguished or tilt to middle part simultaneously, make goods go all to transfer to up hill and dale on emptying equipment, and oil cylinder is hidden in vehicle frame simultaneously, increases effective cargo capacity in compartment.
Preferably, when described oil cylinder 4 fully extends, removable bottom 212 is 40-45 degree with the angle β of the horizontal direction of vehicle frame 1.
As further preferred version, β is 43 degree.Adopt this technical scheme, the goods be deposited on L shape gusset can be made thoroughly to transfer on emptying equipment.
Preferably, the height of described mobile side board 211 is less than the height of fixed side 23.
As further preferred version, the height of described mobile side board 211 is less than 1/2nd of fixed side 23 height.Due to the unloading gradually along with goods, the upper plane of goods falls gradually, generally can not exceed the half of car side board, therefore adopts this technical scheme, not only reduces cost, also further increases effective cargo capacity in compartment.
