Abstract
The utility model relates to a connecting structure between parts of a concrete mixer, in particular to a welding structure between a sub beam and a back bracket inclined brace of the concrete mixer. The welding structure comprises the sub beam and the back bracket inclined brace, wherein a backing plate is additionally arranged between the sub beam and the back bracket inclined brace. Compared with the prior art, the welding structure between the sub beam and the back bracket inclined brace of the concrete mixer, provided by the utility model, has the advantages as follows: as the backing plate is additionally arranged between the sub beam and the back bracket inclined brace, stress of the connecting structure between the sub beam and the back bracket inclined brace is distributed in a balanced way, so that rigidities on the sub beam and the back bracket inclined brace are enhanced, bending moment and torque resisting capacity is enhanced and open welding accidents of the sub beam are reduced.
Description
Technical field:
The utility model relates to the connection structure between a kind of mixermobile parts, the welded structure between particularly a kind of mixermobile auxiliary girder and after poppet diagonal ligament.
Background technology:
The concrete mixer truck tank body is installed on the subframe through front and back support.Front and back support is positioned at the subframe rear and front end.Cause subframe to bear tank body through front and back support effect two place's concentrated loads above that.Cause subframe when full-loading condition, to bear bigger moment of flexure and moment of torsion.The after poppet diagonal ligament be connected with the after poppet front end above the auxiliary girder.The after poppet diagonal ligament fuses auxiliary girder and after poppet.Stressing conditions to auxiliary girder has improvement.But fully loaded generous measuring tank body is when the complex road condition long-term use, and near auxiliary girder and after poppet diagonal ligament junction, auxiliary girder still can rupture.Mainly there is following shortcoming in this kind structure:
After poppet integral body is in vehicle rear overhang district, is cantilever design.Auxiliary girder in use produces than macrobending and is out of shape here.And be in the anterior auxiliary girder suspension chassis structural constraint of vehicle rear wheel, be out of shape little.After poppet diagonal ligament two ends distortion difference is big.The after poppet diagonal ligament and above the auxiliary girder junction stress concentration serious.
Auxiliary girder is the rectangle rhs-structure.Its underpart and chassis ridgepole are adjacent to.The outside is connected with chassis ridgepole through thrust plate.Its top is few with inboard constraint.Distortion is big.With after poppet diagonal ligament junction, constraint is few above the auxiliary girder, and distortion is big.
Under above-mentioned 2 combineds action, generous amount Mixer Truck auxiliary girder CRACKING ACCIDENT becomes concrete mixer truck and is prone to the accident of sending out.And early stage cracking mostly occurs above near auxiliary girder and after poppet diagonal ligament junction the auxiliary girder and the inboard.
The utility model content:
The goal of the invention of the utility model is the welded structure that provides in order to reduce auxiliary girder to snap accident between a kind of mixermobile auxiliary girder and after poppet diagonal ligament.
The technical scheme of the utility model is:
Welded structure between a kind of mixermobile auxiliary girder and after poppet diagonal ligament comprises auxiliary girder, after poppet diagonal ligament, sets up backing plate between said auxiliary girder and the after poppet diagonal ligament.
The utility model that adopts technique scheme is compared with prior art: set up backing plate between auxiliary girder and the after poppet diagonal ligament; The connection structure distribution of stress of the two is balanced; Strengthen the rigidity at auxiliary girder and after poppet diagonal ligament place, improve the ability of opposing moment of flexure and moment of torsion, reduce auxiliary girder and snap accident.
The preferred version of the utility model is:
Said backing plate is L type structure.
Top and the inboard face of said auxiliary girder intermittently welds with said backing plate respectively.
Be provided with two chamfers above the said backing plate, the top interrupted welding of this two chamfer and said auxiliary girder.
Said backing plate side is provided with the plug welding hole, the inboard interrupted welding of said plug welding hole and auxiliary girder.
The two ends of said backing plate side are provided with gap, the inboard interrupted welding of this gap and auxiliary girder.
Said after poppet diagonal ligament and backing plate middle part successive welding.
Said backing plate length is greater than ﹥ 800mm.
Said backing plate length is 860 mm.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the cross sectional drawing of auxiliary girder and backing plate connection structure.
Fig. 3 is the front view of backing plate.
Fig. 4 is the birds-eye view of backing plate.
Fig. 5 is the lateral plan of backing plate.
The specific embodiment:
Below in conjunction with embodiment the utility model is detailed:
Welded structure between a kind of mixermobile auxiliary girder and after poppet diagonal ligament is referring to accompanying drawing 1 to accompanying drawing 4, among the figure: auxiliary girder 1, backing plate 2, after poppet diagonal ligament 3, after poppet 4, crossbeam 5, gap 6, plug welding hole 7, top 8, chamfering 9, side 10.
In the present embodiment, set up backing plate 2 between auxiliary girder 1 and the after poppet diagonal ligament 3; Reduce the CRACKING ACCIDENT of auxiliary girder 1.The rear end of after poppet diagonal ligament 3 is connected with after poppet 4; The transversal surface of backing plate 2 is L type structure; Top and the inboard face of auxiliary girder 1 intermittently welds with backing plate 2 respectively.
Backing plate 2 top 8 on two ends be provided with the top interrupted welding of chamfering 9, two chamfers 9 and auxiliary girder 1.The side 10 of backing plate 2 is provided with plug welding hole 7, plug welding hole 7 and auxiliary girder 1 inboard interrupted welding.10 two ends, side of backing plate 2 are provided with gap 6, gap 6 and auxiliary girder 1 inboard interrupted welding; After poppet diagonal ligament 3 and backing plate 2 middle part successive weldings.The length of backing plate 2 is 860 mm.
The rigidity of backing plate 2 is less than auxiliary girder 1 and after poppet diagonal ligament 3; The structural distortion of ability release portion makes the integral structure distribution of stress balanced.
Auxiliary girder 1 is balanced with after poppet diagonal ligament 3 connection structure distributions of stress, strengthens the rigidity at auxiliary girder 1 and after poppet diagonal ligament 3 places, improves the ability of opposing moment of flexure and moment of torsion, reduces the accident of snapping of auxiliary girder 1.
Those skilled in the art technology general knowledge can know, the utility model can be realized through other technical characterictic or the embodiment of essential feature of equivalent substitution.Therefore, above-mentioned disclosed embodiment, just casehistory is not unique.All in the utility model scope or the change that is being equal in the utility model scope all be regarded as within the protection domain of the utility model.
