The specific embodiment
Need to prove, in the situation that clearly do not limit or do not conflict, the feature in each embodiment of the present utility model can make up mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.
In order to overcome the defective of jib braced structures in prior art, the utility model provides the jib braced structures after a kind of the improvement.
Fig. 3 is the decomposing schematic representation according to jib braced structures of the present utility model, and as shown in Figure 3, the jib braced structures after improvement comprises bracing frame 1, a pair of gusset 2, support member 3, connector 4, cushion 5, a plurality of packing ring 6 and a plurality of bolt 7.
Wherein, bracing frame 1 is circular or square column structure for the cross section, and in order to improve the stability of bracing frame 1, its lower end also can arrange a supporting seat that sectional area is larger, thereby has increased the contact area between support member 1 and supporting surface (for example ground).Certainly, consider the convenience of processing, other suitable shape also can be adopted in the cross section of bracing frame 1.
In the present embodiment, the box structure of connector 3 opening upwards (in the exploded view of Fig. 3 as opening to the right) when using, common circle or square also can be adopted in its cross section.The bottom surface of connector 3 is connected by the mode of welding with the top of bracing frame 1, thereby connector 3 is fixedly installed on the top of bracing frame 1.
In order to increase the stability of the connection between bracing frame 1 and connector 3, two ends at bracing frame 1 top in the present embodiment are provided with a pair of gusset 2, described gusset 2 connects bracing frame 1 and connector 3, particularly, each gusset 2 connects a part of side at bracing frame 1 top and a part of bottom surface of support member 3.Certainly, the quantity of gusset 2 is not limited to a pair of, can be also one or more, and the durability requirements when its quantity can be used according to reality decides.
In the present embodiment, connector 4 is arranged at the inside of support member 3 in use, be in the cavity of box structure, and the upper surface of connector 4 is higher than the height of the opening of bracing frame 3, thereby the upper surface that guarantees connector 4 under any circumstance all protrudes from the cavity of support member 3, like this, and could be at the parts of the upper surface setting example of connector 4 such as cushion 5 and so on, and then contact the supporting role of actual performance jib braced structures with object to be supported (for example jib).
The upper surface of connector 4 can connect cushion 5 by one or more detachable apparatus.Described detachable apparatus can comprise packing ring 6 and bolt 7, also can adopt other common structure.Described cushion 5 can adopt polyurethane material, thereby enough elasticity is provided, and when the jib braced structures is used, can play certain cushioning effect, the braced structures below protection cushion 5.
According to improvement of the present utility model, at least a portion of connector 4 is positioned at the top of support member 3, and be provided with arrangement for adjusting height between support member 3 and connector 4, described arrangement for adjusting height makes connector 4 removable Shang Xia 3 with respect to support member, thereby regulated the height of the upper surface of connector 4, and then adjusted the whole height of jib braced structures.
In the present embodiment, described arrangement for adjusting height is the filler of the variable volume between the soffit of the inner bottom surface (being the bottom surface of its internal cavities) of bracing frame 3 and connector 4.Described filler can choose sand, polyurethane sheet and so on can bearing certain pressure material.By regulating the volume of described filler, just can change the distance between the soffit of the inner bottom surface of support member 3 and connector 4, thereby change the height of connector 4, finally change the whole height of jib braced structures, realized the purpose of regulating arm frame support structure height.
View when the jib braced structures that Fig. 4 to Fig. 6 shows embodiment of the present utility model is used, wherein, Fig. 4 is in the schematic diagram of minimum constructive height according to jib braced structures of the present utility model, Fig. 5 be according to jib braced structures of the present utility model mediate the height schematic diagram, Fig. 6 is in the schematic diagram of maximum height according to jib braced structures of the present utility model.
In Fig. 4, there is no or almost do not have filler between the soffit of the inner bottom surface of support member 3 and connector 4, the inner bottom surface of support member 3 and the soffit of connector 4 are in contact with one another at this moment, and the jib braced structures is in minimum height.In Fig. 5, has the filler of a constant volume between the soffit of the inner bottom surface of support member 3 and connector 4, distance between the soffit of the inner bottom surface of support member 3 and connector 4 is H at this moment, compare with aforementioned minimum constructive height, the whole height of jib braced structures has increased H, and height mediates.In Fig. 6, basically filled up filler in support member 3, but connector 4 is not still deviate from from the opening of support member 3, distance between the soffit of the inner bottom surface of support member 3 and connector 4 is L at this moment, compare with aforementioned minimum constructive height, the whole height of jib braced structures has increased L, has reached maximum height.
In another embodiment of the present utility model, described arrangement for adjusting height is the drive unit between support member 3 and connector 4.This drive unit comprises driving cylinder and expansion end, and certainly, this expansion end is driven by driving cylinder, and can change within the specific limits the collapsing length of expansion end.Described driving cylinder can adopt the mode of common driven by power cylinder, hydraulic drive cylinder or air pressure driving cylinder.
This driving cylinder and expansion end can for example be connected to respectively support member 3(, its upper surface) or connector 4(for example, its soffit), for example, driving cylinder is connected to the upper surface of support member 3 and the soffit that expansion end is connected to connector 4, otherwise perhaps, expansion end is connected to the upper surface of support member 3 and the soffit that driving cylinder is connected to connector 4.Like this, by changing the collapsing length of expansion end, just can adjust the distance between support member 3 and connector 4, thus whole height that can the regulating arm frame support structure.
At this moment, support member 3 can be not limited to the box structure of opening upwards, can be also platy structure for example; Connector 4 still can adopt the box-structure of platy structure or hollow.
Jib braced structures of the present utility model has been described according to embodiment in the front, but this jib braced structures is not limited in the parts described in this embodiment and/or annexation, and for example, the jib braced structures can not comprise gusset and/or cushion; Arrangement for adjusting height is not limited to filler and the drive unit of variable volume, can also adopt other the common device that can regulate relative altitude between two articles, such as turbine and worm structure, ball screw arrangement etc.; Support member and connector also are not limited to the shape in embodiment, but can adopt various possible shapes, as long as at least a portion of connector can realize the purpose of the utility model above support member and between support member and connector, relative to each other the up and down is removable.
The utility model also relates to a kind of pump truck, and it has the jib braced structures of aforementioned arbitrary embodiment and the described structure of modification thereof.
The above is only preferred embodiment of the present utility model, is not limited to the utility model, and for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
