Please also refer to Fig. 6, Fig. 8 and Fig. 9, Fig. 6 is the structural representation of tail end hose device among first kind of embodiment of the utility model; Fig. 8 is the structural representation of second kind of embodiment tail end hose device of the utility model; Fig. 9 is the structural representation of tail end hose device among the third embodiment of the utility model.
In the utility model, tail end hose device provided by the utility model is used for concrete mixer, and described concrete mixer comprises boom, and described tail end hose device comprises carrier pipe 1, and carrier pipe 1 is connected with the end of described boom; On this basis, the lateral wall of carrier pipe 1 is set with quality dish 2, and has the gap between the lateral wall of the inner ring sidewall of quality dish 2 and carrier pipe 1, and the purpose that has the gap between the two is in order to realize that quality dish 2 can move vertically with respect to carrier pipe 1; In the above and below of quality dish 2, have at least a side to be provided with the support portion that protrudes from carrier pipe 1 lateral wall, be connected by elastomeric element between quality dish 2 and the described support portion, so that quality dish 2 is along the axial double vibrations of carrier pipe 1.
By above-mentioned mechanical type simple harmonic oscillation power vibration damping theory as can be known, this device can be converted into the vibrational energy of carrier pipe 1 kinetic energy of quality dish 2, thereby the vibration of carrier pipe 1 will decay.In addition, by above-mentioned introduction as can be known, vibration-proof structure provided by the utility model relatively simple for structure only comprises quality dish 2, described flexible member and described support portion, thereby manufacturing cost and maintenance cost are lower; Moreover, because vibration-proof structure provided by the utility model is pure mechanical vibration-proof structure, thereby be easy to realize having higher functional reliability.Simultaneously, vibration-proof structure provided by the utility model also can be used in the jib vibration damping of open hydraulic control system to a certain extent.
At this, need to prove, in technique scheme, set-up mode for described support portion does not limit, such as can be for along the equally distributed brace summer of carrier pipe 1 circumferential side wall, the opposite position of each brace summer and quality dish 2 is connected a flexible member, thereby realizes quality dish 2 purpose of double vibrations vertically, and then realizes the vibration damping purpose for carrier pipe 1; Certainly, described support portion can also be loaded on the ring-type gripper shoe of carrier pipe 1 outside for fixed cover, will discuss in detail hereinafter this.
Moreover, need to prove that also in technique scheme, comprise three kinds of embodiments: one for only being provided with described support portion and described flexible member above quality dish 2; Two for only being provided with described support portion and described flexible member below quality dish 2; Three for to be equipped with described support portion and described flexible member in the above and below of quality dish 2, will elaborate hereinafter this embodiment.
As Fig. 6, Fig. 8 and shown in Figure 9, the above and below of quality dish 2 is equipped with described support portion, is respectively first support portion 31 of being located at quality dish 2 tops and second support portion 32 of being located at quality dish 2 belows; Be provided with between the roof of first support portion 31 and quality dish 2 between first flexible member, 41, the second support portions 32 and quality dish 2 diapires and be provided with second flexible member 42.Because tail end hose device needs the mobile working position, especially the tail end hose device of concrete mixer needs mobile working position as required, thereby the weight of quality dish 2 can not be too big; And as can be known by the power vibration damping theory of above-mentioned simple harmonic oscillation, under the little situation of the weight of quality dish 2, the rigidity of flexible member is also little, thereby when only below quality dish 2, flexible member being set, probably cause quality dish 2 in the process of motion, the amplitude that moves upward is very big, probably causes quality dish 2 and first support portion 31 (that is roof of cylinder sleeve hereinafter described 3) to bump, thereby influences the reliability of work.And in the technical program, because the above and below of quality dish 2 is equipped with flexible member, thereby quality dish 2 can not bump with first support portion 31 or second support portion 32 in vibration processes, and then improved the reliability of work.
As indicated above, the structure of described support portion is specifically as follows the ring-type gripper shoe.Particularly, as Fig. 6, Fig. 8 and shown in Figure 9, first support portion 31 is the first ring-type gripper shoe, and second support portion 32 is the second ring-type gripper shoe, and the described first ring-type gripper shoe and the described second ring-type gripper shoe fixed cover are loaded on the lateral wall of carrier pipe 1.With respect to above along the structure design of a plurality of brace summers of the circumferential distribution of carrier pipe 1, the structure design of this kind ring-type gripper shoe, installation procedure is less, installs more convenient; In addition, because working environment is more abominable, this kind ring-type gripper shoe can also play the effect of protective cover to quality dish 2 and elastomeric element, prevents that the object of quality dish 2 above and belows from interfering quality dish 2 and elastomeric element, thereby influences its damping property.
Please also refer to Fig. 6, Fig. 8 and Fig. 9, further, be provided with tubular wall 33 between the circumferential outer end of the circumferential outer end of first support portion 31 and second support portion 32, and the internal diameter of tubular wall 33 greater than or be slightly larger than the external diameter of quality dish 2 cause interference so that prevent the motion of 3 pairs of quality dishes 2 of tubular wall; The quality dish is located in the cavity that the sidewall of first support portion 31, tubular wall 33, second support portion 32 and corresponding carrier pipe 1 surrounds, and in this cavity under the drive of carrier pipe 1 double vibrations vertically.In this scheme, the setting of tubular wall 33 further is isolated in quality dish 2 and described flexible member in the cavity of sealing fully, thereby its course of work can not be subjected to extraneous interference, and the reliability of its work is further enhanced.In addition, the existence of tubular wall 33 has also improved the safety of working, and the staff can contact with tubular wall 33 by hand or other hold assemblies as safe as a housely, thereby moves described conveyance conduit device to the predetermined work position.
Need to prove that first support portion 31, second support portion 32 and tubular wall 33 can be the split structure, link together by welding or other connected modes; Certainly, first support portion 31, second support portion 32 and tubular wall 33 all right integrated components, by cylinder sleeve 3 of outside suit at carrier pipe 1, the roof of this cylinder sleeve 3 forms first support portion 31, the diapire of this cylinder sleeve 3 forms second support portion 32, and the circumferential side wall of this cylinder sleeve 3 forms tubular wall 3; Obviously, with respect to above-mentioned minute body structure, this structure design can reduce amount of parts, reduced assembly process, and then reduced assembly cost.
