The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the utility model is described in detail.
In the process of implementing the concrete distributing jib, the utility model people finds that the joint arm that different materials is made is used in combination, can alleviate the cloth jib weight, reach the spread length of expection.Cloth jib with six joint arms is that example describes below.
Fig. 1 shows the engineering truck that is equipped with according to the concrete distributing jib of the utility model preferred embodiment.As shown in the figure, this cloth jib comprises joint arm 11,12,13,14,15 and 16, and these joint arms are mounted thereon for elephant trunk 17, and drives the predetermined cloth position of elephant trunk 17 arrival.
At least one end of every joint arm directly links to each other by the joint arm of parts and front or back, perhaps divides with the engineering truck undercarriage portion to link to each other.
Support portion 11e makes carrier pipe can adopt riveted way to link to each other with girder 11a for carrier pipe provides a gap.
The part that forms support portion 11c can adopt a mould manufacturing and then height as required to be cut into some.This makes that for the joint arm of any other constant cross-section, the part that forms the support portion can adopt identical mould manufacturing.
Fig. 4 shows the cross section of Fig. 1 or joint arm shown in Figure 2.As shown in Figure 4, the cross section of this joint arm 12 is rectangular substantially, is embedded with metal reinforcement 121 and 122 in the two side.For example all embedding or part are passed body structure, or surfaces externally and internally is herein pasted this metal reinforcement.
Metal reinforcement 121,122 reinforcements with the fiber manufacturing use, and the intensity that can increase hinged stub area is with stress in the opposing work and wearing and tearing.
Metal reinforcement shown in Fig. 4 (be generally and be called inserts) 121,122 is a metal sheet form.Metal reinforcement 123,124 shown in Fig. 5 is for lattice-shaped, to form vertical reinforcement or the horizontal form of strengthening.Metal reinforcement 126 shown in Figure 6 can be surrounded by tank material, connects by the anchoring fiber 127 that passes the inner hole 125 of metal sheet itself.
Fig. 7 shows another schematic cross-section of joint arm 12.As shown in Figure 7, joint arm 12 is made of box girder 12a, is provided with lining 128 and 129 on the two side of box girder 12a.Different with Fig. 4, Fig. 5 and cross section shown in Figure 6, this box girder 12a is made by composite material, is not provided with metal reinforcement in the sidewall.The joint arm of this cross section structure can save arm endways or use near the position of end segment arm, further to alleviate the weight and volume of joint arm.
The structure of joint arm 13 can similar joint arm 12,11, as shown in Figure 8, the end of the box girder 13a of joint arm 13 forms connecting portion 13b, is used for being connected with last joint arm 12, be fixed with clamping plate 134 by bearing pin 133 on the other end, to form the connecting portion that is connected with back one joint arm 14.Be fixed with part 131 by bearing pin 132 on joint arm 13, this part 131 is used for the connection of motion oil cylinder.Along under the situation of brachium direction convergent, the girder section of joint arm 12 and joint arm 13 can keep constant along the brachium direction, certainly, also can dwindle gradually along the brachium direction at the girder section that saves arm 11.
An axial hole is arranged in the lining 131,132, so as between the joint arm that composite material is made interconnective the time as the positioning seat of pin.
Lining preferably adopts corrosion resistant metal material to make, and inserts in the through hole that processes on the above-mentioned sidewall in forming process with matching.
Specifically, lining 131,132 not only can be applied on the case shape girder 14a of associated section arm, also can be used on the connecting portion, and is fixing on the parietal layer that composite material is made with the mode of glueing joint.
According to the utility model, metal lining the 131, the 132nd, splicing is got on, so do not need to process in the step of back again.
For the central axis of the central axis that guarantees lining 116 and girder 11a is vertical mutually, can mill out in the side that composite material is made or bore step, and the inclination of side is the needs of deviating from from mould for product.
Figure 10 shows the another kind of optional cross section structure of joint arm 14, as shown in figure 10, this joint arm 14 comprises metal framework 14c and is covered in the composite fibre layer 14a of metal framework 14c both sides, this metal framework 14c also can be called metal inner core, is characterized in that the metal inner core outer side covers has one or more layers composite fibre layer.Compare with joint arm 11,12,13, the joint arm of this structure has the advantages that to strengthen joint arm rigidity.
It will be understood by those skilled in the art that the top mentioned metal arm and the structure of each intermediate arm between the composite material reinforcement arm can be used for adjacent intermediate arm, to be combined into the cloth jib of lighter weight.The various types of joint arms that above provided according to the utility model are provided and save the instruction that arm is used in combination, can be combined into the multiple cloth jib that satisfies instructions for use.
The used composite material of joint arm is made of carbon fiber, aramid fibre or other like fibrous of matrix and implantation matrix in the above-mentioned cloth jib, the fiber of implanting matrix can be the unidirectional form or the form that interweaves, what wherein, the joint arm was used can be multilayer materials.
The above is a preferred embodiment of the present utility model only, is not limited to the utility model, and 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 being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
