The specific embodiment
Hereinafter will describe the utility model with reference to the accompanying drawings and in conjunction with the embodiments in detail.Need to prove that under the situation of not conflicting, embodiment and the feature among the embodiment among the application can make up mutually.
To shown in Figure 7, according to embodiment of the present utility model, the jib bracing or strutting arrangement comprises support column 10 and supporting seat 20 as Fig. 4, and supporting seat 20 comprises base plate 23 and the bullet pad 24 that is fixedly installed on the base plate 23.Supporting seat 20 is arranged on the support column 10 rotationally, supporting seat 20 has the supporting surface 21 that support angle is adjusted with the rotation of supporting seat 20, can change support angle according to the jib moment of torsion produce that tilts, make between the supporting surface of jib and supporting seat 20 can to contact by maintenance face all the time.
After jib draws in, respectively saving jib and all can support by the jib bracing or strutting arrangement outside the basic arm of jib, when jib run-off the straight that the jib bracing or strutting arrangement supports, because supporting seat 20 is rotatable with respect to support column 10, and the rotation of supporting seat 20 can make it support corresponding the changing of supporting surface of jib, and finally adapt to the inclination of jib, make that remaining face between supporting seat 20 and the jib contacts, can effectively prevent from forming between jib and the supporting seat 20 line contacts, avoid jib to produce the rollover moment of torsion to connecting bearing pin, prevent that jib from deforming, prolong the application life of jib, improve the safety that jib uses.
Preferably, in the present embodiment, hinged by bulb 22 between support column 10 and the supporting seat 20.The top of support column 10 is set with bulb mount pad 11, the bottom of the base plate 23 of supporting seat 20 is provided with the bulb 22 that matches with bulb mount pad 11, can be one machine-shaping between bulb 22 and the base plate 23, also can be welding, can also for example be spirally connected etc. for removably connecting.Bulb 22 is arranged in the bulb mount pad 11, and can multi-angle freely rotate in bulb mount pad 11, thereby can adapt to the various inclinations of jib preferably.
When one-body molded between the base plate 23 of bulb 22 and supporting seat 20, clamp 12 comprises first plate and second plate, two plates are installed on the bulb mount pad 11 from the both sides side direction respectively, after first plate and the second plate installation, whole clamp 12 is fastened on the contraction flow region of bulb 22, and bulb 22 is spacing in bulb mount pad 11.Preferably, the sphere draw-in groove that is complementary for the shape with bulb 22 of the draw-in groove 121 of clamp 12.Draw-in groove 121 also can be rectangular channel or elliptical slot etc., deviates to get final product in clamp 12 and bulb mount pad 11 formed bulb installation cavitys as long as its opening, can effectively prevent bulb 22 less than the cross section of the bulb 22 that is positioned at it.
When removably being connected between the base plate 23 of bulb 22 and supporting seat 20, then clamp 12 can as a whole structure, and this moment, the clamp middle part was provided with opening, opening be shaped as sphere, and opening is along dwindling gradually away from the direction of bulb mount pad 11.When bulb 22 is installed, can at first bulb 22 be installed on the bulb mount pad 11, then clamp 12 is set in outside bulb 22, and is fixed on the bulb mount pad 11, thereby bulb 22 is limited in clamp 12 and the bulb mount pad 11 formed bulb installation cavitys.
The bottom of support column 10 can also fixedly install a base, and the jib bracing or strutting arrangement is fixedly installed on the jib carrier by this base, and this carrier for example is vehicle frame.
When the hold-down arm rack supporting device, at first support column 10 is welded on the supporting traverse of jib, then bulb mount pad 11 is welded on the support column 10.Afterwards bulb 22 is put into the hemispherical groove 111 of bulb mount pad 11, be divided into first plate and second plate with clamp 12() it is blocked, because clamp 12 middle circle cambered surfaces are that spherical diameter is the same with supporting seat lower sphere diameter with base, top arc diameter is little, following arc diameter is big, the bulb that can guarantee supporting seat 20 bottoms like this can normally rotate, and can not break away from the control of clamp 12 again.After treating that clamp 12 location are finished, be fixed on the bulb mount pad 11 with bolt.Again bullet pad 24 usefulness bolts are installed on the base plate 23 at last, thereby finish the erection work of whole jib bracing or strutting arrangement.
When jib drops on the bullet pad 24, supporting seat 20 is by the adjusting of sphere, can guarantee well between bullet pad 24 and the jib that maintenance face contacts always, and the strength of jib drops on half sphere, the impact energy that is subjected to for jib plays good cushioning effect like this.
In other embodiments, supporting seat 20 can be set to arrange rotationally around horizontal rotating shaft, particularly, can be set to can arrange on swing ground around horizontal rotating shaft by supporting seat, perhaps can arrange around horizontal rotating shaft with swinging.When supporting seat be can swing state the time, then can have conformability preferably to tilting forward and back of jib.When supporting seat is the state that can swing, then can have compliance preferably to tilting of jib.
Certainly, the jib bracing or strutting arrangement is had simultaneously and adapt to the braced structures that jib tilts all around.In such cases, only need to make connector with respect to support column 10 around the horizontal rotating shaft swing and supporting seat 20 is swung around horizontal rotating shaft with respect to connector, perhaps make connector swing and supporting seat 20 is got final product around the horizontal rotating shaft swing with respect to connector around horizontal rotating shaft with respect to support column 10.In such cases, no matter then how jib tilts, the jib bracing or strutting arrangement all can be adjusted automatically at the situation of its inclination, makes supporting surface remain face with the jib bottom surface and contacts.
According to embodiment of the present utility model, concrete mixer comprises jib and supports the jib bracing or strutting arrangement of jib that this jib bracing or strutting arrangement is above-mentioned jib bracing or strutting arrangement.
According to embodiment of the present utility model, engineering machinery comprises the jib bracing or strutting arrangement, and this jib bracing or strutting arrangement is above-mentioned jib bracing or strutting arrangement.
As can be seen from the above description, the utility model the above embodiments have realized following technique effect:
1, the jib bracing or strutting arrangement can guarantee well that with respect to existing bracing or strutting arrangement it is that face contacts that jib drops on when jib supports, and has greatly improved for jib is stressed.
2, when there is certain angle of inclination in the jib soffit with supporting surface, can guarantee that jib drops on the jib bracing or strutting arrangement completely, like this in the pump truck driving process, just can reduce the impact that causes because the road surface is rugged, the fatigue of jib there is good cushioning effect.
3, to connecting the impact of bearing pin, increase the application life of bearing pin in the time of can reducing to tilt because of jib, reduce potential safety hazard.
Be preferred embodiment of the present utility model only below, be not limited to the utility model, for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
