Abstract
The utility model discloses a boom lorry-mounted crane base, and belongs to the technical field of crane bases. The boom lorry-mounted crane base comprises main boards, a rear web plate, shaft sleeves, an upper cover plate, a front web plate, circular reinforcing plates, reinforcing plates and a base plate, wherein two main boards arranged in parallel are welded on the base plate; a shaft sleeve is welded between two pairs of hinged holes corresponding to the upper parts of the two main boards; a circular reinforcing plate is welded inside each hinged hole at the bottom of each main board, and the reinforcing plates are welded outside; the bottom of the rear web plate is welded on the base plate, both sides of the rear web plate are welded on the two main boards, and the upper side of the rear web plate is connected with the back shaft sleeve; the two shaft sleeves are welded with the two main boards together through the upper cover plate; and the front shaft sleeve, the two main boards and the base plate are welded together through the front web plate. Compared with the existing base structure, by using few reinforcing rib plates and welding beads, the boom lorry-mounted crane base is simpler in structure and lighter in weight, and uniformly stressed during the using process; and on the basis of ensuring the structure reliability, the production cost and structure weight of the product are reduced.
Description
Technical field
The utility model relates to a kind of folding arm lorry-mounted crane base, belongs to hoisting crane base technical field.
Background technology
The folding arm lorry-mounted crane is an important component part of elevator machinery, is widely used in fields such as cargo handing, engineering construction.Wherein, folding arm lorry-mounted crane base is the connection structure between jib and the following chassis of getting on the bus, and is main load member, requires it to have higher structure stiffness.
Existing base generally is welded into body structure by regular plates such as mainboard, webs, and part is strengthened with the triangle gusset again.Because of mainboard, web design form old stuff, complex structure, it is many to strengthen gusset, and welding bead is many, finally causes distribution of stress unreasonable, and structural weight is laid particular stress on, and has increased complete vehicle weight, the cost height.
Summary of the invention
At the problem that above-mentioned prior art exists, the utility model provides a kind of folding arm lorry-mounted crane base, and it is simple in structure, in light weight, stressed evenly, is guaranteeing to reduce production cost of products and structural weight on the structural reliability basis.
To achieve these goals, the technical solution adopted in the utility model is: a kind of folding arm lorry-mounted crane base, comprise mainboard, trailing web, axle sleeve, upper cover plate, leading web, circular brace panel, brace panel and base plate, be welded with the mainboard of two parallel placements on the base plate, be welded with an axle sleeve respectively between two pairs of hinge holes of two mainboard top correspondences, the inboard, hole in every mainboard bottom-hinged hole is welded with circular brace panel, and the outside is welded with brace panel; The bottom of trailing web is welded on the base plate, and both sides are welded on two mainboards, and upside is connected on the axle sleeve of back; Upper cover plate is with two axle sleeves and two mainboard weld togethers; Leading web is with the axle sleeve of front, two mainboards and base plate weld together.
The multi-section circular arc transition is adopted in the outside of mainboard.
Brace panel is connected with mainboard edge, base plate arc-shaped transition.
The place is provided with the triangle lightening hole in the middle of the mainboard, and the edge of triangle lightening hole adopts the great circle arc transition.
The beneficial effects of the utility model are: compare existing understructure, the reinforcement gusset that the utility model uses is few, and welding bead is few, structure is simpler, in light weight, in the use stressed evenly, guaranteeing to have reduced production cost of products and structural weight on the structural reliability basis.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is front view of the present utility model;
Fig. 3 is assembling dismounting figure of the present utility model.
Among the figure: 1, mainboard, 2, trailing web, 3, axle sleeve, 4, upper cover plate, 5, leading web, 6, circular brace panel, 7, brace panel, 8, base plate.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As Fig. 1, Fig. 2 and shown in Figure 3, a kind of folding arm lorry-mounted crane base, comprise mainboard 1, trailing web 2, axle sleeve 3, upper cover plate 4, leading web 5, circular brace panel 6, brace panel 7 and base plate 8, be welded with the mainboard 1 of two parallel placements on the base plate 8, be welded with an axle sleeve 3 respectively between two pairs of hinge holes of two mainboard 1 top correspondences, the inboard, hole in every mainboard 1 bottom-hinged hole is welded with circular brace panel 6, and the outside is welded with brace panel 7; The bottom of trailing web 2 is welded on the base plate 8, and both sides are welded on two mainboards 1, and upside is connected on the axle sleeve 3 of back; Upper cover plate 4 is with two axle sleeves 3 and two mainboard 1 weld togethers; Leading web 5 is with the axle sleeve 3 of front, two mainboards 1 and base plate 8 weld togethers.
During use, can finally be welded into the box-structure of a sealing by above-mentioned position relation with each parts weld together.Place, two mainboard 1 bottom-hinged holes is used for connecting oil cylinder, and by the circular brace panel 6 of inboard welding in the hole, welding brace panel 7 in the outside can be strengthened the local stiffness of hinge hole.This structure is in use stressed even, can guarantee structural reliability.
Preferably, multi-section circular arc 12 transition are adopted in the outside of mainboard 1, and brace panel 7 also adopts arc-shaped transition to be connected with mainboard 1 edge, base plate 8, can strengthen local structure, guarantee stressed evenly, have avoided the appearance of areal of stress concentration.
Preferably, the place is provided with triangle lightening hole 11 in the middle of the mainboard 1, and the edge of triangle lightening hole 11 adopts the great circle arc transition, and further expendable weight is guaranteed stressed even.
