Abstract
The present invention supports balance system for a kind of special purpose vehicle, is set up in parallel before and after the first span system and the second span system in exhibition system, and the length after two span systems are shunk coordinates the width in compartment；Fixed cavity and span section are respectively divided into wherein each span system, span section stretching motion in fixed cavity, the end of span section is vertically respectively arranged with support system, support system is divided into the first support system again, second support system and the first span system, second span system is corresponding, the fixed cavity end of first span system and the second span system is provided with U-typed structural openings groove respectively inwards, open slot is vertically communicated and will be accommodated respectively after the first support system and the contraction of the second support system, increase the area after the span, the setting of its fixed cavity open ended slot accommodates after shrinking the first support system and the second support system, length due to hydraulic cylinder after its expansion extends, lifting surface area is added in limited scope.
Description
Technical field
The present invention relates to the support system of special-purpose vehicle, specifically a kind of special purpose vehicle support balance system.
Background technology
Special crane and truck-mounted crane extensive use, in order to increase stability, it is necessary to it is had a stable center of gravity,
So expand stress reason area, stable center of gravity by the way of pull wing hydraulic support leg.
But every kind of vehicle, which is all bulletin, is made that size and tonnage limitation, the purpose is to ensure the safety and matter of vehicle
Amount, its size cannot be arbitrarily changed after size limitation, can only be transformed in former scope, but by the shadow of hydraulic system
Ring, hydraulic system can not possibly make multistage and prolong the wing, while multistage prolongs reduction and width ultra-wide that the wing also results in intensity, direct shadow
Ring automobile bulletin and the security-hidden trouble of itself.
The content of the invention
In order to make in the range of being announced in vehicle special purpose vehicle effectively expand lifting surface area, spy proposes a kind of the present invention
Special purpose vehicle supports balance system.
For this, the technical scheme is that, a kind of special purpose vehicle supports balance system, including span system, span system
In the first span system and the second span system before and after be set up in parallel, the length after two span systems are shunk coordinates compartment
Width；Fixed cavity and span section, span section stretching motion in fixed cavity, the wing are respectively divided into wherein each span system
The end of exhibition section is vertically respectively arranged with support system, and support system is divided into the first support system, the second support system and the again
One span system, the second span system are corresponding, it is characterised in that：The lock chamber of first span system and the second span system
Body end portion is provided inwardly with open slot respectively, and open slot is vertically communicated and respectively shrinks the first support system and the second support system
After accommodate.
Further improve is：Described span system is square hydraulically extensible system.
Further improve is：First support system and the second support system are cylindricality hydraulic system.
Further improve is：Described open slot is U-typed structure.
Beneficial effect：
The first span system and the second span system are set up in parallel the increase of the area after can making the span, its lock chamber in the present invention
The setting of body open ended slot accommodates after shrinking the first support system and the second support system, due to hydraulic cylinder after its expansion
Length extension, so its lifting surface area also can add lifting surface area with increase in limited scope.
Square hydraulically extensible system is advantageous to bear gravity.
The convenient manufacture of cylindricality hydraulic system and use, while be also beneficial to support.
The use of U-typed structure is the storage for the vertical hydraulic cylinder body for facilitating cylindricality, while has a peace after storage
Full storage environment.

Embodiment
The present invention is as shown in Fig. 1/2/3/4.
A kind of special purpose vehicle supports balance system, including span system, the first span system 1 and second in span system
It is set up in parallel before and after span system 2, the length after two span systems contractions coordinates the width in compartment；Wherein each span system
In be respectively divided into fixed cavity 3 and span section 4, the stretching motion in fixed cavity 3 of span section 4, the end of span section 4 is vertically divided
Support system is not provided with, and support system is divided into the first support system 5, the second support system 6 and the first span system 1, again
The correspondence of two span system 2, the end of fixed cavity 3 of first span system 1 and the second span system 2 is provided with respectively inwards opens
Mouthful groove 7, open slot 7 is vertically communicated and accommodates after respectively shrinking the first support system 5 and the second support system 6.
The first span system 1 and the second span system 2 in span system are square hydraulically extensible system.
First support system 5 and the second support system 6 are cylindricality hydraulic system.
Described open slot 7 is U-typed structure.
The U-typed design feature of the end of fixed cavity 3 of the present invention：
In equal box width size, U-typed structure ratio increase after the original system span effective bearing length 160*2=
320mm, so as to increase lorry-mounted crane job stability.
