The specific embodiment
In order to understand the utility model in depth, below in conjunction with drawings and the specific embodiments, the utility model is elaborated.
Referring to accompanying drawing 3 and 4, the diagonal ligament supporting leg that the utility model provides comprises fixed supporting leg 5, movable supporting legs 3, linear force application apparatus 4, supporting disk 8.Its neutral line force application apparatus 4 can be hydraulic ram, can also be the devices such as jack, as long as the device that can continue the application of force to movable supporting legs can reach technique effect of the present utility model; As preferably, we select hydraulic ram as linear force application apparatus 4 in the present embodiment, and we select the strip square steel of hollow as the structure of fixed supporting leg 5 and movable supporting legs 3 simultaneously, and such selection also can reach technique effect of the present utility model.What fixed supporting leg 5 tilted is welded on vehicle frame 9, and reinforces by 1 pair of point of connection of the second reinforced rib; Fixed supporting leg 5 has pin-and-hole I, and pin-and-hole I coordinates one end of hydraulic ram 4 is connected in to fixed supporting leg 5 inside with bearing pin I 2; On movable supporting legs 3, have pin-and-hole II, pin-and-hole II coordinates the other end of hydraulic ram 4 and movable supporting legs 3 is fixed together with bearing pin II 7.Movable supporting legs 3 is enclosed within the inside of fixed supporting leg 5 and forms a sliding pair, referring to attached Fig. 1 and 2, movable supporting legs 3 can slide along the length direction of fixed supporting leg 5 under the promotion of hydraulic ram 4, and then drive the relative car body of supporting disk 8 outwards to stretch out downwards, supporting disk 8 can increase 4 distances between the hydraulic ram strong point to overhanging, and then increased the ability of bearing moment of flexure of installing, and further reduce the possibility of slide-out, guarantee job safety.Between movable supporting legs 3 and fixed supporting leg 5, be provided with regulating plate, because in supporting leg assembling, there is certain gap between fixed supporting leg 5 and movable supporting legs 3, in order to prevent excessive clearance, we arrange the size that regulating plate changes gap.The bottom of movable supporting legs 3 and the plane-welding of semi-round ball are fixed, supporting disk 8 forms a revolute pair with the hemisphere face of semi-round ball, semi-round ball can make supporting disk 8 guarantee that by rotation the base plate of supporting disk 8 and ground fit tightly, and guarantees whole vehicle stablizing when work.
Referring to accompanying drawing 3, the first reinforced rib 11 and brace panel 10 are welded on fixed supporting leg 5, and be in the position that fixed supporting leg 5 contacts with movable supporting legs 3, brace panel 10 is set in the position contacting with movable supporting legs 3 at fixed supporting leg 5 and the first reinforced rib 11 is in order to ensure that supporting leg is when working, fixed supporting leg 5 does not destroy the deformation of shape at the position contacting with movable supporting legs 3 under the effect of power or moment, thereby can avoid device damage or work accident.
Referring to accompanying drawing 3,3 the second reinforced ribs 1 of position welding that are connected with vehicle frame 9 at fixed supporting leg 5, because junction for this reason bearing motive power and moment is very complicated, and in the easiest destroyed position of supporting leg, so the load-carrying capacity that the second reinforced rib 1 improves this junction is set, contributes to improve the load-carrying properties of whole supporting leg and the safety and stability of work.
Referring to attached Fig. 1 and 2, four diagonal ligament supporting legs are assembled on vehicle, fixed supporting leg 5 be in tilted layout and 4 diagonal ligament supporting legs be assembled to vehicle after integral body be X-type, by fixed supporting leg 5 is in tilted layout, and then hydraulic ram 4 is also arranged on an obliquity, the action effect of the hydraulic ram 4 tilting so is just equivalent to a vertical and coefficient effect of cross cylinder, has simplified the structure of device and has improved the operating efficiency of installing and the fault rate that has reduced device feature like this with regard to actv..And by 4 diagonal ligament supporting legs symmetrical being arranged on vehicle all around, be in order to guarantee the stability of car load, avoid occurring slide-out, guarantee job safety.
Referring to accompanying drawing 5, after 4 diagonal ligament supporting legs are assembled to vehicle, in order to strengthen load-carrying capacity and the stability of each supporting leg, also set up quadruplet auxiliary support mechanism 6; Auxiliary support mechanism 6 comprises base plate I 12, strut bar 13, base plate II 14; Base plate I 12 is welded on brace panel 10; Base plate II 14 is welded on vehicle frame 9; Fixedly journal stirrup 16 and the base plate I 12 of one end of strut bar 13 are connected by bolt, and fixedly journal stirrup 16 and the base plate II 14 of the other end are connected by bolt; Strut bar 13 comprises fixedly journal stirrups 16 of 17 and two of the bodies of rod 15, two bar covers, and the body of rod 15 two ends are threaded connection with two bars covers 17, the length of the number of teeth adjusting strut bar 13 by screw-threaded engagement; Fixedly journal stirrup 16 is hinged for two 17 and two, bar covers, and the fixedly journal stirrup 16 at strut bar 13 Jun Kerao two ends, two ends rotates; Arranging like this can make auxiliary support mechanism 6 be assembled on vehicle more easily.Base plate I 12 is welded on brace panel 10, and brace panel 10 is welded on fixed supporting leg 5, and auxiliary support mechanism 6 is fixed together fixed supporting leg 5 and vehicle frame 9 so, has further strengthened the load-carrying capacity of supporting leg.Base plate I 12 is welded on brace panel 10, can alleviates like this bearing pressure of fixed supporting leg 5 and vehicle frame 9 welds, the structure breaking of anti-weld generation stress deformation here or commissure and cause breakdown of equipment or damage causing contingency; Meanwhile, base plate I 12 is welded on brace panel 10 and can also improves fixed supporting leg 5 at the stressing conditions at the position contacting with movable supporting legs 3, further reduce fixed supporting leg 5 in the possibility of external force or moment loading generation destructive distortion, improve the safe reliability of supporting leg.
Diagonal ligament supporting leg and vehicle in novel for this use; because the structure of using fixed supporting leg 5 and movable supporting legs 3 to combine; can guarantee that 4 of hydraulic rams that tilt bear axial force; and power in other directions is born by fixed supporting leg 5, movable supporting legs 3, supporting disk 8 and auxiliary support mechanism 6; can well protect hydraulic ram 4 like this, improve the reliability of inclination supporting leg.
The vehicle of the diagonal ligament supporting leg that the utility model provides and use supporting leg, by being obliquely installed supporting leg and adopting the structure combining at fixed supporting leg and movable supporting legs to make whole hydraulic ram simple for structure, stable and reliable for performance, safety while having improved the stability of vehicle and operation, has particularly met the requirement of extraordinary vehicle-mounted equipment Industry.
The above-described specific embodiment; object of the present invention, technical scheme and beneficial effect are further described; institute is understood that; the foregoing is only the specific embodiment of the present invention; be not limited to the present invention; within the spirit and principles in the present invention all, any modification of making, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
