Detailed description of the invention
The exemplary embodiments embodying the utility model feature & benefits will describe in detail in the following description.Be understood that the utility model can have various changes in different embodiments, it neither departs from scope of the present utility model, and explanation wherein and to be shown in be the use explained in essence, and be not used to limit the utility model.
As shown in Figure 3 and Figure 4, an embodiment of the tank type half-trailer that the utility model proposes.In the present embodiment, this tank type half-trailer mainly comprises tractor, vehicle frame 1, tank body 2 and two hydraulic rams 3.Wherein tank body 2 is carried on vehicle frame 1, and the rear end of tank body 2 is articulated with vehicle frame 1.The position that vehicle frame 1 both sides are corresponding is respectively equipped with a supporting leg 4 (namely two supporting legs 4 are as the criterion with vehicle frame 1 line of centers and are symmetrical arranged).
As shown in Figure 3 and Figure 4, in the present embodiment, hydraulic ram 3 has first end and the second end (i.e. the first end of lifting mechanism and the second end).The position that vehicle frame 1 is provided with two supporting legs 4 is respectively arranged with a support 5, each support 5 is fixed with first free bearing, two the first free bearings are in order to the first end of hinged two hydraulic rams 3 respectively.Middle front part position bottom tank body 2 is fixed with two the second free bearings, in order to the second end of respectively hinged two hydraulic rams 3, and two the second free bearings are as the criterion with tank body 2 line of centers and are symmetrical arranged (that is two the second free bearings be as the criterion with vehicle frame 1 line of centers be symmetrical arranged).In addition, the projection of hydraulic ram 3 in the plane perpendicular to tank body 2 axis is vertical shape.This tank type half-trailer adopts two groups of hydraulic rams 3 arranged side by side to be located at the both sides of supporting leg 4 respectively, cross-tie point is added while improving lifting stability, make the deflection angle of hydraulic ram 3 in lifting process less, then tank body 2 gives rise to extreme higher position and is more not easy to have a down dip, and reduces the rollover risk of tank type half-trailer.In addition, the leading section of tank body 2 is positioned at compared to the lifting mechanism of existing tank type half-trailer and the connection location of tank body 2, second end (the second free bearing) of the hydraulic ram 3 of the tank type half-trailer that the utility model proposes is articulated with the position more in the middle part of tank body 2, this design makes lifting fulcrum more near the geometric centre of tank body 2, improves the force-bearing situation of tank body 2 in lifting process.In addition, because the second end of hydraulic ram 3 is arranged at middle front part position bottom tank body 2 by the second free bearing, the lifting mechanism of more existing tank type half-trailer further shorten lifting stroke, decreases the time of lifting and reset, improves handling efficiency and operation benefits.
Further, as shown in Figure 3, in the present embodiment, the relation of the spacing of the articulated position of two free bearings (the first free bearing and the second free bearing) and tank body 2 and vehicle frame 1 is preferably roughly equal, i.e. LA ' C ' ≈ LB ' C ', this structure design makes the stressing conditions of hydraulic ram 3 in lifting process more optimize, in other embodiments, said structure can adjust, not as limit according to vehicle frame 1 and the practical structures of tank body 2 and the setting position of supporting leg 4.
It should be noted that, in other embodiments, the structure of the first free bearing and the second free bearing can other structures replace, not as limit, but need ensure on two symmetries (be as the criterion with vehicle frame 1 line of centers and the be symmetrical arranged) position that the first end of hydraulic ram 3 is articulated with on vehicle frame 1, and the second end of hydraulic ram 3 is articulated with bottom tank body 2 and (is as the criterion with vehicle frame 1 line of centers and is symmetrical arranged), namely two hydraulic rams 3 respectively telescopically be arranged between vehicle frame 1 and tank body 2, realize the lifting to tank body 2.In addition, in other embodiments, can also other structure replacement liquid compressing cylinders 3, as the lifting mechanism of tank type half-trailer, not as limit.
As shown in Figure 3 and Figure 4, can find out that the tank type half-trailer that the utility model proposes substitutes existing lifting structures with a kind of lifting structures of middle, two groups of hydraulic rams 3 arranged side by side are adopted to lay respectively at the left and right sides (i.e. the position of two supporting legs 4) of vehicle frame 1, be welded in supporting leg 4 position the first end of a support 5 fixed hydraulic oil cylinder 3, as the fixed pivot B of hydraulic ram 3, and hydraulic ram 3 lifting fulcrum A is made to be positioned at middle front part position bottom tank body 2.As can be seen from the figure, under, lifting angle is identical, lifting speed is identical prerequisite identical in vehicle, the lifting structures of middle can make lifting stroke greatly shorten (LA ' B ' < LAB).When the angle of lifting, speed are identical, the stroke of lifting is shorter, and lifting is shorter with the time needed for resetting, and handling efficiency is higher.Originally be adopt two groups of hydraulic rams 3 arranged side by side to lay respectively at vehicle frame supporting leg 4 both sides diligently, add cross-tie point while improving lifting stability, in lifting process, the deflection angle of oil cylinder is less, and rollover risk is lower.After tank body 2 lifting, ∠ A ' B ' C ' is more close to 90 °, and the stability after lifting is better, and tank body 2 gives rise to extreme higher position and is more not easy to have a down dip, and reduces the potential safety hazard in operation, reduces the probability of the generation of safety misadventure.
Though exemplary embodiment describe tank type half-trailer of the present utility model with reference to several, should be understood that term used be illustrate and illustrative, and not restrictive.Specifically can implement in a variety of forms due to the utility model and not depart from its design or essence, therefore, above-described embodiment is not limited to any aforesaid details, and explain widely in the design that should limit in claim of enclosing and scope, therefore the whole change fallen in claim or its equivalent scope and remodeling all should be claim of enclosing and contained.
