Abstract
The utility model relates to a self-unloading semi-trailer. In order to omit the trailer frame of the self-unloading semi-trailer, a traction seat and an oil cylinder are combined into integration. Special points are that the oil cylinder 2 is connected with a tractor 1 through a bearing seat 16. The top of the oil cylinder 2 is movably connected with the trailer body 14 of the semi-trailer. A stabilizer bar 6 is movably connected with a stabilizer bar 8 through a connection pin. The other end of the stabilizer bar 6 is movably connected with a circular ring arm 4. The other end of the stabilizer bar 8 is connected with the trailer body 14 of the semi-trailer. The circular ring arm 4 is movably sleeved on the oil cylinder 2. A traction sleeve 10 which is fixedly combined with the trailer body 14 of the semi-trailer is connected with the oil cylinder 2 and the circular ring arm 4 through a connecting pin 13.
Description
The utility model belongs to field of transport machinery, particularly about self-discharging semitrailer.
At present, known produces the CSZ9170QC self-discharging semitrailer by Changshu, it is that vertical vehicle frame is housed below the compartment, traction seat is contained between tractor truck and the semi-trailer frame, tractor truck and superimposed trailer are tied, connect with trip shaft between semi-trailer frame and compartment, two oil cylinders are housed between compartment and vehicle frame.When the self-unloading goods, tractor truck, traction seat, semi-trailer frame are motionless, under the effect of hydraulic coupling, and two oil cylinders elongations, the compartment is during around the trip shaft rotating certain angle, and goods will be unloaded automatically.Mainly there is following problem in it, owing to below the compartment vehicle frame is housed, the car load deadweight is increased, and load capacity descends, and manufacturing cost improves, and structure is not compact.
The purpose of this utility model is to provide a kind of traction seat and oil cylinder is integrated, below the compartment not with the novel self-discharging semitrailer of vehicle frame.
The purpose of this utility model can reach by following measure: a kind of self-discharging semitrailer, has tractor truck 1, oil cylinder 2, superimposed trailer compartment 14, superimposed trailer wheel (15), it is characterized in that, by supporting base 16 oil cylinder 2 and tractor truck 1 are tied, oil cylinder 2 tops and superimposed trailer compartment 14 link joints, stabilizer rod 6 passes through connecting pin 7 link joints with stabilizer rod 8, the other end of stabilizer rod 6 and annulus arm 4 link joints, the other end of stabilizer rod 8 and superimposed trailer compartment 14 connect, annulus arm 4 is bound up on the oil cylinder 2, with the fixed traction casing 10 in superimposed trailer compartment 14 by coupling pin 13 and oil cylinder 2, annulus arm 4 connects.
The utility model can reach by following measure: oil cylinder 2 has two axles and a hole.
The utility model can also reach by following measure: annulus arm 4 by an annulus and on its relative direction fixed two arms form, and on annulus, have the hole.
The utility model can also reach by following measure: traction casing 10 and has the hole ringwise on its circumference.
Compared with the prior art the utility model has the following advantages: owing to saved vehicle frame, traction seat and oil cylinder are integrated, and the car load deadweight is reduced, and the charge material amount improves, and manufacturing cost descends, and structure is compact more.

1 tractor truck, 2 oil cylinders, 3 coupling pins, 4 annulus arms, 6 stabilizer rods, 7 coupling pins, 8 stabilizer rods, 9 coupling pins, 10 traction casings, 13 coupling pins, 14 superimposed trailer compartments, 15 superimposed trailer wheels, 16 supporting bases.
Be described in further detail as follows below in conjunction with accompanying drawing embodiment:
Fig. 1 is the situation of self-discharging semitrailer when not working.Oil cylinder 2 not only plays the effect of lifting goods, also play the effect of traction and bearing load, see Fig. 4, Fig. 5, Fig. 6, cylinder body has two axles and a hole, elongate slots can be made in the hole of cylinder body, with supporting base 16 oil cylinder 2 and tractor truck 1 are linked up, oil cylinder 2 tops and superimposed trailer compartment 14 usefulness hinges link.From Fig. 7, Fig. 8, Fig. 9 as seen, traction casing 10 ringwise, and have elongate slots thereon, traction casing 10 is to be welded on securely on the superimposed trailer compartment 14, and be enclosed within versatilely on the cylinder body of oil cylinder 2, elongate slots by oil cylinder 2 and traction casing 10, annulus arm 4 usefulness coupling pins 13 are tied the three, and the three can only move in the horizontal direction mutually, must not be in movement in vertical direction.Annulus arm 4 is enclosed within on the oil cylinder 2 versatilely, can not move up and down, can only rotate around oil cylinder 2 horizontal directions, coupling pin 3 is tied annulus arm 4 and stabilizer rod 6 versatilely, coupling pin 7 is tied stabilizer rod 6,8 versatilely, and coupling pin 9 gets up stabilizer rod 8 and superimposed trailer compartment 14 link joints.
The utility model service condition is as follows: when need are unloaded, take off towing pin 13, see Fig. 3, tractor truck 1 is motionless, under the effect of hydraulic coupling, along with the elongation of oil cylinder 2, oil cylinder 2 is vertically being put certain angle, at this moment, superimposed trailer wheel 15 rolls forward, and after stabilizer rod 6,8 was drawn as a certain angle, two bars were by the boss contact, angle no longer increases, and goods is unloaded automatically.When the need return, under the gravity pressure in superimposed trailer compartment 14, oil cylinder 2 is pushed back original position, the superimposed trailer wheel 15 original position of also rolling back, stabilizer rod 6,8 also is pulled back to original position, and traction casing 10 is enclosed within on the oil cylinder 2, refill coupling pin 13 and get final product, see Fig. 1.
