Abstract
The utility model relates to a steel-scrap silo transport vehicle, in particular to a traction device used in the steel-scrap silo transport vehicle. The silo lifting traction device of a semi-trailer traction-type steel-scrap silo transport vehicle comprises a rear frame the back bottom of which is provided with a vehicle bridge. The lifting traction device is arranged on the rear frame and comprises two lifting fuel cylinders, a connecting arm, a double-freedom-degree saddle and a suspension arm. The fuel cylinders are provided with a support in the middle, and the piston rods of the lifting fuel cylinders are arranged upwards. The support is fixed on the tail of the rear frame and the middle of the fuel cylinders are hinged with the support. One end of the connecting arm is hinged with the top of the rear frame, and two sides of the other end are respectively hinged with the ends of the piston rods of the lifting fuel cylinders. The double-freedom-degree saddle is connected with the upper surface of the end where the connecting arm is connected with the fuel cylinders. One end of the suspension arm is fixed on the -freedom-degree saddle, and the other end of the suspension arm is a hanger. The traction device provided by the utility model can lift the silo and hang the silo on the traction vehicles; and the traction device can be guided by the traction vehicles to run, thereby being convenient for steel-scrap transportation.
Description
Technical field
The utility model relates to steel scrap hopper transport trolley, especially relates to a kind of draw gear of steel scrap hopper transport trolley.
Background technology
The main at present dual mode that adopts of domestic steel mill steel scrap charging technology.One class is a railway transportation, its technological process is: the steel scrap hopper that the waste steel ingredient field will prepare material lifts on the railway chassis by transfer crane, be transported to steelshop by train then, by the steelshop crane in bridge type hopper is winched to and treat charging zone, it is reinforced to be sling by crane in bridge type when needing to feed in raw material again.Another kind of is the flat truck transportation, and technological process and railway transportation are basic identical, just replaces the railway chassis to come working expenses steel hopper with flat truck.
All there is obvious defects in these two kinds of transportation modes, railway transportation Facilities Construction input cost on the one hand is bigger, operating cost is also high, and is subjected to very much the restriction of site condition, is not suitable for the technological requirement of this type of short-distance transportation steel scrap hopper and the cooperation that loading-unloading vehicle all needs weight-lifting equipment.Flat truck transportation steel scrap hopper except loading-unloading vehicle all needs the cooperation of weight-lifting equipment, also have a fatal defective be exactly the vehicle body of its overlength in the workshop inner turn or to have bad luck hopper very inconvenient.Produce needs in order to guarantee in addition, the outfit quantity of equipment is also not little, has also caused the increase of cost.
Therefore, the applicant develops the towed steel scrap hopper of a kind of semi-mounted, its bottom has been installed wheel and can have been walked, but, because walk after making this type of hopper fill steel scrap, needed tractive force reaches hundreds of thousand Ns, the trailer coupling undercapacity of common tractor truck, under so huge tractive force effect, be damaged easily, need development separately.
Summary of the invention
The utility model is intended to address the above problem, and the hopper jacking draw gear of the towed steel scrap hopper of a kind of semi-mounted transport trolley is provided.The utility model can hold up hopper, and hopper is hung on the towing vehicle, walks under the traction of tractor truck, has made things convenient for the steel scrap transportation.
The utility model is achieved in that the hopper jacking draw gear of the towed steel scrap hopper of a kind of semi-mounted transport trolley, comprises that bottom, band back has the back vehicle frame of wheel set, and described jacking draw gear is installed on the vehicle frame of back, and it comprises:
Two middle parts have the oil cylinder of lifting of bearing, and their piston rod upwards is provided with, and described bearing is fixed on the afterbody of back vehicle frame, and oil cylinder middle part cylinder body and bearing are hinged;
One connecting arm, the one end is hinged with vehicle frame top, back, and two sides of the other end are respectively with described to lift the oil cylinder piston rod end hinged;
One double freedom saddle, it is installed in the upper surface that connecting arm connects the oil cylinder end;
One hangs arm, and its end is fixed on the described double freedom saddle, and the other end is hook.
The hopper jacking draw gear of the towed steel scrap hopper of described semi-mounted transport trolley, the hook of described extension arm are the outside C shape of opening.
The hopper jacking draw gear of the towed steel scrap hopper of described semi-mounted transport trolley, the swing angle of described double freedom saddle are 10 °-18 °.
The hopper jacking draw gear of the towed steel scrap hopper of described semi-mounted transport trolley, the nearly saddle of described connecting arm position be provided with control oil cylinder stroke near switch.
Arm is hung in the utility model utilization will tangle hopper, utilize two to lift oil cylinder the hopper front portion is lifted, and can walk under the traction of towing vehicle, and because saddle has the beidirectional degree of freedom, turn round conveniently, satisfy the short-distance transportation needs of some steel scraps.
Description of drawings
Below, the present invention is further illustrated in conjunction with the accompanying drawings:
Fig. 1 is the utility model front elevation;
The specific embodiment
As shown in Figure 1: the hopper jacking draw gear of the towed steel scrap hopper of a kind of semi-mounted transport trolley comprises:
With pin bonded assembly front vehicle frame 112 and back vehicle frame 111 vertically are set, front vehicle wheel bridge (failing among the figure to illustrate) is equipped with in front vehicle frame 112 bottoms, and back vehicle bridge 13 is equipped with in back vehicle frame 111 bottoms, and hopper traction jacking apparatus also is housed on the vehicle frame 111 of described back;
Two be installed in back vehicle frame 111 afterbodys, the middle part has a bearing 141 lifts oil cylinder 142, their piston rod upwards is provided with, described lift oil cylinder 142 middle part cylinder bodies and bearing 141 hinged;
One connecting arm 145, the one end is hinged with vehicle frame 111 tops, back, and two sides of the other end are respectively with described to lift oil cylinder 142 rod ends hinged;
One double freedom saddle 143, it is installed in connecting arm 145 and connects the upper surface of lifting oil cylinder 142 ends, and its swing angle is 10 °-18 °;
One hangs arm 144, and its end is fixed on the described double freedom saddle 143, and the other end is the outside C shape hook of opening, and the towing pin 22 of described hopper 2 is connected with hook.
