Abstract
The utility model discloses a crane base fixing ground jack structure resolving the base weight bearing problem for a large pedrail crane. The base includes a base faceplate, a base soleplate and a base vertical plate; the fixing ground jack structure includes a reinforced plate, one end of the reinforced plate is connected with the base vertical plate; a support rod is connected between the base faceplate and the reinforced plate. A cushion plate is arranged on the base soleplate. An accommodation space is formed at the joints between the cushion plate and the reinforced plate to fix the ground jacks. The utility model also includes an axis pin and a positioning pin; run-through holes and at least two positioning holes are arranged on the reinforced plate and the base faceplate. The axis pin runs through the run-through hole and is fixed on the fixing jack. The positioning pin runs through the positioning holes and is fixed on the joint of the fixing jack. The utility model provides a box structure consisting of the reinforced plate and the support rod so that the base faceplate and the base vertical plate are of an integral structure, which improves the force bearing performance, increases the rigidity of the base and reduces the distortion of the base when bearing the force.
Description
Technical field
The utility model relates to the hoisting crane technical field, particularly large-scale crawler crane base fixed supporting leg structure.
Background technology
Goliath is bulky, the main stressed member of base conduct, and easy deformation under tens of ton force weight, the thickness that simply increases material can increase the overall weight of host machine part again greatly, brings inconvenience for the transportation of equipment.Improve large-scale crawler crane base stressing conditions for hoisting crane, make base stressed more reasonable, thereby strengthen the rigidity of base, the distortion that reduces stressed rear base solves, at present beyond example still.
Summary of the invention
The purpose of this utility model is a kind of hoisting crane base fixed supporting leg structure of design, improves large-scale crawler crane base stressing conditions, makes base stressed more reasonable, thereby strengthens the rigidity of base, reduces the anamorphic attachment for cinemascope of stressed rear base; Solve uncontrolled rotatablely move of supporting leg in transportation simultaneously.
To achieve these goals, the technical solution of the utility model is: hoisting crane base fixed supporting leg structure, be installed on the base, and this base comprises base panel, base plate, base riser, this base riser is fixed between base panel, the base plate; Comprise that brace panel, an end are connected on the base riser between described base panel, the base plate, with base panel, the parallel placement of base plate; At least one strut bar is connected between base panel and the brace panel; Backing plate is arranged on the base plate, forms the accommodation space of installing for the connecting portion of base fixed supporting leg between backing plate and the brace panel.
Further, described base panel, base plate, base riser, brace panel form a box type construction.
The utility model also comprises bearing pin, locating dowel pin; On described brace panel, the base panel respectively correspondence have through hole and at least two knock holees; This bearing pin passes the connecting portion that through hole on brace panel, the base panel is stretched at the base fixed supporting leg; This locating dowel pin passes the connecting portion that knock hole on brace panel, the base panel is stretched at the base fixed supporting leg.
Again, described brace panel one end is welded to connect on the base riser.
Described strut bar is welded to connect between base panel and brace panel.
The utility model makes base panel, base riser connect as a whole by brace panel, strut bar, form a box type construction, run through base with a bearing pin when mounted and connect supporting leg, thereby improved the thin situation in former steel plate part of the force, make base stressed more reasonable, thereby strengthen the rigidity of base, reduce the distortion of stressed rear base.
Advantage of the present utility model is:
1. simple in structure, succinct, realization and cost are lower easily;
2. simple to operate, reliability is higher;
3. motion parts is that bearing pin connects easy accessibility.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment.
The specific embodiment
Further specify structure of the present utility model below in conjunction with accompanying drawing.
Referring to Fig. 1, hoisting crane base fixed supporting leg structure of the present utility model is installed on the base 1, and this base 1 comprises base panel 11, base plate 12, base riser 13, and this base riser 13 is fixed between base panel 11, the base plate 12; This hoisting crane base fixed supporting leg structure comprises, brace panel 2, two strut bars 3,4, backing plate 5, bearing pin 6, locating dowel pin 7;
Wherein, brace panel 2, one ends are connected on the base riser 13 between described base panel 11, the base plate 12, with base panel 11, base plate 12 parallel placements; Two strut bars 3,4 are connected between base panel 11 and the brace panel 2; Backing plate 5 is arranged on the base plate 12, forms the accommodation space of installing for the connecting portion 81 of base fixed supporting leg 8 10 between backing plate 5 and the brace panel 2;
On described brace panel 2, the base panel 11 respectively correspondence have through hole 21,111 and knock hole 22,112; This bearing pin 6 passes the connecting portion 81 that through hole 21,111 on brace panel 2, the base panel 11 is stretched at base fixed supporting leg 8; This locating dowel pin 7 passes the connecting portion 81 that knock hole 22,112 on brace panel 2, the base panel 11 is stretched at base fixed supporting leg 8.
In structure of the present utility model, base panel 11, base riser 13, base plate 12 is stressed main body, brace panel 2 is connected as a whole with strut bar 3,4 with base panel 11, base plate 12, base riser 13, form a box type construction, make base 1 stressed more reasonable, thereby strengthen the rigidity of base 1.
During mode of operation, base 1 is connected with supporting leg 8 usefulness bearing pins 6, and casing and base 1 are whole stressed, strengthens the rigidity of base 1, reduces the distortion of stressed rear base 1.
Simultaneously, reserved two knock holees (shown in the figure one) for locating dowel pin 7 on base 1, promptly control position and transporting position have solved the non-control rotation problem of supporting leg when transportation.
