Abstract
The utility model provides a novel bidirectional rotary supporting foot margin. The foot margin is characterized in that supporting foot lug plates are provided with circular holes, the upper end and the lower end of a connection block are respectively provided with a cylindrical boss, the left end and the right end of the connection block are respectively provided with an installation hole, two foot margin lug plates are provided with circular holes, the connection block is arranged in the two foot margin lug plates, the two foot margin lug plates are welded to the foot margin, a connection shaft is coaxially installed in the circular holes of the two supporting foot lug plates and the installation holes at the left end and the right end of the connection block, the cylindrical bosses at the upper end and the lower end of the connection block are coaxially fixed in the circular holes in the two foot margin lug plates, and the two supporting leg lug plates are welded on supporting legs. The foot margin has the advantages of being capable of forming a support on the smooth ground and on the convex-concave ground, large in supporting force, high in stability and flexible in motion.
Description
Technical field
The utility model relates to a kind of support lower margin, particularly a kind of novel two-way rotational support lower margin.
Background technology
Rapid emergence along with China Construction Machinery, construction machinery and equipment repacking vehicle brings very big facility for the production of all trades and professions, as wrecker, and lorry-mounted crane, car hosit, concrete pump truck, aerial platform etc., and this type of repacking vehicle all has a common characteristic---the configuration supporting leg, the effect of supporting leg in this type of remoulded car is, increase car chassis and prop up the ground breadth, enhancing scope of work and the car load that does not cause because of the operation load carrying ability are tumbled, and improve the performance of car load.And lower margin is very important component part in the supporting leg, last chord leg, following ground plane.The lower margin that the supporting leg of present domestic all kinds of remoulded cars is prepared has two kinds, a kind of unidirectional rotation, and this kind lower margin is useful in smooth ground supports, and is not suitable for scraggly ground supports.Alternative is the lower margin of realizing universal rotation by oscillating bearing, though the structure of this class lower margin has realized in scraggly ground supports, but its bearing force can not satisfy large-scale construction machinery and equipment repacking vehicle, because the degree of freedom of itself is not restricted, so when work, lower margin play phenomenon often occurs, the operation of construction machinery and equipment repacking vehicle be affected.
Summary of the invention
The purpose of this utility model is the deficiency that exists in the above-mentioned technology, a kind of novel two-way rotational support lower margin is provided, be a kind of can be in ground grading, again can be in the convex-concave ground supports, bearing force is big, stability is high, the novel two-way rotational support lower margin of flexible movements.
The purpose of this utility model is achieved in that and comprises two supporting leg otic placodes, two lower margin otic placodes, supporting leg, adapter shaft, connect piece, lower margin, it is characterized by: on two otic placodes circular hole is arranged all, the upper and lower side that connects piece has cylinder boss respectively, end has mounting hole respectively about company's piece, on two lower margin otic placodes circular hole is arranged all, connecting piece is installed in two lower margin otic placodes, two lower margin otic placodes are welded on the lower margin, adapter shaft is coaxial to be installed in two circular holes on the supporting leg otic placode, in the mounting hole of end, connect coaxial being fixed in two circular holes on the lower margin otic placode of cylinder boss of the upper and lower side of piece about the company's of passing piece.Two supporting leg otic placodes are welded on the supporting leg body.
The beneficial effects of the utility model are: can be in ground gradings, and having can be in the convex-concave ground supports, and bearing force is big, stability is high, flexible movements.

The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further
By Fig. 1-6 as can be known, on two supporting leg otic placodes 2 circular hole is arranged all, the upper and lower side of adapter shaft 3, company's piece 4, company's piece 4 has cylinder boss respectively, end has mounting hole respectively about company's piece 4, on two lower margin otic placodes 5 circular hole is arranged, lower margin 6, connecting piece 4 is installed in two lower margin otic placodes 5, two lower margin otic placodes 5 are welded on the lower margin 6, adapter shaft 3 is coaxial be installed in two circular holes on the supporting leg otic placode 2 and connect piece 4 about in the mounting hole of end, connect coaxial being fixed in two circular holes on the lower margin otic placode 5 of cylinder boss of the upper and lower side of piece 4.Two supporting leg otic placodes 2 are welded on the supporting leg 1.
By Fig. 1-3 as can be known, coaxial being fixed in two circular holes on the lower margin otic placode 5 of cylinder boss that connects the upper and lower side of piece 4, afterwards two lower margin otic placodes 5 are welded on the lower margin 6, be to realize that the cylinder boss with the upper and lower side that connects piece 4 is axle, two lower margin otic placodes 5 rotate about the cylinder boss of the upper and lower side that connects piece 4 is done synchronously with lower margin 6, and all the other do not rotate.
By Fig. 1-3 again as can be known, adapter shaft 3 is coaxial be installed in two circular holes on the supporting leg otic placode 2 and connect piece 4 about in the mounting hole of end, be to realize with adapter shaft 3 be axle, connect piece 4, lower margin otic placode 5 and lower margin 6 and do synchronous front and back to rotation.Thereby realize the rotation of two kinds of directions, i.e. two-way rotation.
Claims (2)
1. novel two-way rotational support lower margin, comprise two supporting leg otic placodes, two lower margin otic placodes, supporting leg, adapter shaft, connect piece, lower margin, it is characterized by: on two otic placodes circular hole is arranged all, the upper and lower side that connects piece has cylinder boss respectively, end has mounting hole respectively about company's piece, on two lower margin otic placodes circular hole is arranged all, connecting piece is installed in two lower margin otic placodes, two lower margin otic placodes are welded on the lower margin, adapter shaft is coaxial to be installed in two circular holes on the supporting leg otic placode, in the mounting hole of end, connects coaxial being fixed in two circular holes on the lower margin otic placode of cylinder boss of the upper and lower side of piece about the company's of passing piece.
