Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.A kind of crawler lifting mechanism for crawler type high-altitude operation car shown in Fig. 1 to Fig. 5 comprises symmetrically arranged left and right crane 11,12 and left and right hoist cylinder 6,7, left and right hoist cylinder 6,7 one end is fixed on the underframe 10 of aerial platform by cylinder support 8, two cylinder supports 8 are symmetrically welded at the top of underframe 1, left and right hoist cylinder 6,7 is crisscross arranged, and with cylinder support 8 chain connection of respective side.
As shown in Figure 1, described left and right crane 11,12 is by side stand 1 and upper and lower support 3,2 composition being set in parallel in side stand 1 upper and lower end, side stand 1 is welded by high-strength panel, make the shape of similar " C " type, two cranes are fixed on crawler belt support body 9 bottom of respective side respectively by side stand 1, described lower bracket 2 is also welded by high tensile steel plate, makes arc; Upper ear plate 5 is welded with respectively in the both sides on the top of underframe 10, both sides, underframe 10 bottom are welded with lower ear plate 4 respectively, two lower ear plates 4 are connected as a single entity, form a U-shaped plate, be set in bottom underframe 10, often picking up the ears, the block of plate 5 is several to be determined according to support, guarantees that support can be fixed on otic placode by bearing pin, and can rotate along bearing pin.The upper bracket 3 of left and right crane 11,12 is hingedly coupled to B point with the upper ear plate 5 of respective side on underframe 10 respectively, lower bracket 2 is hingedly coupled to C point with the lower ear plate 4 of respective side on underframe 10 respectively, side stand 1 one end of each crane and upper bracket 3 are articulated with A point, one end and lower bracket 2 are articulated with D point, described side stand 1 forms parallelogram four-bar mechanism with upper bracket 3, lower bracket 2 and underframe 10, that is: the quadrangle ABCD be made up of hinge is parallelogram, and its hinge-point A, B, C, D are respectively four summits of parallelogram four-bar mechanism.The support body of each crawler belt is equipped with two identical these parallelogram four-bar mechanisms, to ensure that car load center of gravity is between two side stands, lack of equilibrium when avoiding car load to walk.
As shown in Figure 1, oil cylinder otic placode 3-1 is welded with in the middle part of the upper bracket 3 of left and right crane 11,12, one end of left and right hoist cylinder 6,7 is hingedly coupled to E point with the oil cylinder otic placode 3-1 on respective side crane upper bracket 3 respectively, the other end (both piston end) is articulated with F point with the cylinder support 8 of respective side, and is compressed by cover plate 7.The support plate of described lower ear plate 4, upper ear plate 5, cylinder support 8 is made by high tensile steel plate, and support plate is designed to the shape of similar " C " shape.
As shown in Figure 4, each hinge-point place of support all adopts pinned connection, and all bearing pins are made by high strength steel, and the bearing pin at the hinge-point place of hoist cylinder and cylinder support and the cylinder barrel of crawler lifting oil cylinder make one.
The utility model when mounted, install, and is respectively used to the lifting of the crawler belt of the right and left of Operation Van by two left and right crane full symmetrics, and the crawler lifting oil cylinder on both sides need stagger placement, and remaining four-bar mechanism and crawler belt are complete specular.
Operation Van, under walking states, is stretched by the left and right hoist cylinder 6,7 of fluid control crawler belt, thus drives crawler belt to be elevated by parallelogram four-bar mechanism ABCD.Due to the characteristic of parallelogram four-bar mechanism, ensure that crawler belt is in lifting process, steady kiss the earth, can not tilt all the time.When left and right hoist cylinder 6,7 is retracted to minimum stroke, as shown in Figure 5, as this mechanism draws crawler belt in, make car load have minimum collection height, indoor target area work can be arrived by the less door of size and corridor flexibly; When crawler lifting oil cylinder 6 is elongated to range, as shown in Figure 1, this mechanism upwards promotes the distance furthered between two crawler belts, and makes underframe 10 away from ground, thus makes car load have maximum hill climbing ability, can adapt to the field road conditions of various complexity.
The above; it is only preferred embodiment of the present utility model; not the utility model is imposed any restrictions; every above embodiment is done according to technical spirit of the present utility model any simple modification, change and equivalent structure transformation, all still belong in the protection domain of technical solutions of the utility model.
