Abstract
The present invention relates to a kind of supporting leg of heavier-duty arc bending plate.Including inner tube（1）And it is arranged on inner tube（1）The base of bottom（2）, said inner tube（1）And base（2）Pass through arc bent plate（3）Realize connection；The arc bent plate（3）Top is connected to inner tube（1）On, the arc bent plate（3）Bottom is by being installed in base（2）On connecting tube（4）Realize and base（2）Connection；The arc bent plate（3）It is and the connecting tube in the middle part of lower surface（4）The corresponding interior concave arc of outer surface profile, both sides are and said inner tube（1）The transverse part of connection.Bottom of the tube sets reinforcing plate in the supporting leg of the present invention, reinforcing plate is combined with the corresponding close welding in arc bent plate four sides, connecting tube makes inner tube weld more firm with connecting tube, further improves the dead load ability of supporting leg with being fixed on again on the base of supporting leg after curved bend plate weld.
Description
Technical field
The present invention relates to semi-trailer support technical field, more particularly to a kind of supporting leg of heavier-duty arc bending plate.
Background technology
Movable supporting legs are generally equipped in the outside of semitrailer leading portion or so side bar, to assist support semitrailer in handling goods or parking maintenance, and the height of semitrailer can be adjusted according to the actual height of various traction vehicle seats.The polycrystalline substance of traditional interior square tube is only that the wherein two sides of bottom is the circular arc opening of semicircle.By interior square tube bottom with being connected shaft pipe welding, lower shrouding is installed, so as to reach the lifting of supporting leg.But, rhs-structure and loaded area after shaft pipe welding are few in existing supporting leg, and the dead load of supporting leg is limited in one's ability.
The content of the invention
The present invention is directed to drawbacks described above, it is therefore intended that provide a kind of simple in construction, production cost is low, a kind of supporting leg of the high heavier-duty arc bending plate of dead load ability.
It is for this technical solution adopted by the present invention：The present invention includes inner tube（1）And it is arranged on inner tube（1）The base of bottom（2）, said inner tube（1）And base（2）Pass through arc bent plate（3）Realize connection；
The arc bent plate（3）Top is connected to inner tube（1）On, the arc bent plate（3）Bottom is by being installed in base（2）On connecting tube（4）Realize and base（2）Connection；
The arc bent plate（3）It is and the connecting tube in the middle part of lower surface（4）The corresponding interior concave arc of outer surface profile, both sides are and said inner tube（1）The transverse part of connection.
Said inner tube（1）Bottom is set and said inner tube（1）Connected reinforcing plate（5）；
The arc bent plate（3）It is connected in reinforcing plate（5）On, the reinforcing plate（5）Following table facial contour and the arc bent plate（3）Upper table facial contour is correspondingly arranged.
The reinforcing plate（5）Including foreboard, back plate, the foreboard, back plate are constituted by the arc sections at middle part and the transverse part of both sides, its profile and arc bent plate（3）Upper surface is correspondingly arranged.
The arc bent plate（3）The transverse part of both sides is obliquely installed.
The arc bent plate（3）The transverse part angle of inclination of both sides is 10-30 °.
It is an advantage of the invention that：Bottom of the tube sets reinforcing plate in the supporting leg of the present invention, reinforcing plate is combined with the corresponding close welding in arc bent plate four sides, connecting tube makes inner tube weld more firm with connecting tube, further improves the dead load ability of supporting leg with being fixed on again on the base of supporting leg after curved bend plate weld；Compact conformation of the present invention, driving member is few, and technique is simple, and manufacturing cost is low；The reinforcing plate of bottom of the tube can reduce the length of inner tube in supporting leg of the present invention, the lower shrouding of existing supporting leg can be removed, so as to save material；Further reinforcing plate is welded with arc bent plate four sides, is increased welding scope, is added the intensity of inner tube, the dead load ability of supporting leg is brought up to 94 tons by original 70 tons.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Fig. 2 is the structural representation of arc bent plate.
1 it is inner tube in figure, 2 be base, 3 be arc bent plate, 4 be connecting tube, 5 is reinforcing plate.
Embodiment
The present invention includes inner tube 1 and is arranged on the base 2 of the bottom of inner tube 1, and said inner tube 1 and base 2 pass through arc bent plate 3 and realize connection；
The top of arc bent plate 3 is connected in inner tube 1, and the bottom of arc bent plate 3 realizes the connection with base 2 by the connecting tube 4 being installed on base 2；
It is interior concave arc corresponding with the outer surface profile of connecting tube 4, the transverse part that both sides are and said inner tube 1 is connected in the middle part of the lower surface of arc bent plate 3.
The reinforcing plate 5 that the bottom of said inner tube 1 is set and said inner tube 1 is connected；
The arc bent plate 3 is connected in reinforcing plate 5, and the following table facial contour of reinforcing plate 5 and the arc bent plate 3 the upper table facial contour is correspondingly arranged.
The reinforcing plate 5 includes foreboard, back plate, and the foreboard, back plate are constituted by the arc sections at middle part and the transverse part of both sides, and its profile and the upper surface of arc bent plate 3 are correspondingly arranged.
The transverse part of the both sides of arc bent plate 3 is obliquely installed.
The transverse part angle of inclination of the both sides of arc bent plate 3 is 10-30 °.
The present invention is made further instructions below：The supporting leg of the present invention is made up of outer tube, inner tube, gear-box, base 2, its bottom design reinforcing plate 5 of inner tube 1：Reinforcing plate 5 is made up of front and rear panels, foreboard, arc opening of the bottom provided with indent of back plate, and arc opening is semicircle.The transverse part of foreboard, the arc opening of back plate and both sides is welded with strengthening arc bent plate 3；Strengthen being fixed on again on the base 2 of supporting leg after the bottom of arc bent plate 3 is welded with connecting tube 4, reinforcing plate 5 can be stably fixed on base 2 by connecting tube 4, so as to reach the flexible lifting of earth plate 2.
