Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.Should be understood that, detailed description of the invention described herein, only for instruction and explanation of the utility model, is not limited to the utility model.
In the utility model, when not doing contrary explanation, the noun of locality of use such as " inside and outside " refers to profile inside and outside relative to each parts itself, but the above-mentioned noun of locality is not limited to the utility model.
According to detailed description of the invention of the present utility model, a kind of positioning car sub-arm for car dumper system is provided, this positioning car sub-arm comprises for being connected to the jib 12 of described positioning car and being connected to the gib head of jib 12, wherein, described gib head is connected to the end of described jib 12 by elastic component.
Connection between the jib of the positioning car sub-arm for car dumper system that the utility model provides and gib head is improved to elasticity by traditional being rigidly connected and connects, gib head is connected to the end of jib 12 by elastic component, gib head impact to jib 12 under the effect of extraneous impulsive force can be cushioned, thus avoid the steel structure of jib to be damaged, and elasticity connection is realized by the connection structure between gib head and jib, therefore the positioning car sub-arm for car dumper system that the utility model provides can make the connection structure between gib head and jib 12 avoid being subject to the destruction of foreign impacts power.
In the detailed description of the invention that the utility model provides, elastic component can be connected between the end of gib head and jib 12 with the structure of any appropriate and suitable mode, realizes the function of above-mentioned buffering.Describe gib head in detail below with reference to Fig. 4 and try the above-mentioned end that can be connected to jib 12 next year by the form of elastic component elastic telescopic.
In order to ensure that gib head is relative to jib 12 each time flexible all along identical path, fixed muffle is provided with in described jib 12, described gib head comprises slide shaft 161, this slide shaft 161 is arranged through described fixed muffle, thus can by the directional tagging of fixed muffle realization to slide shaft 161, and then facilitate the setting of elastic component, in this case, slide shaft 161 can move relative to fixed muffle and be subject to the effect of the restoring force that elastic component applies.Thus, those skilled in the art are it is understood that when gib head is subject to extraneous impulsive force, the direction of transfer of this impulsive force is: gib head (→ slide shaft 161) → elastic component → fixed muffle → jib 12.Under the effect of impulsive force, one end bias slide axle 161 of elastic component, other end bias voltage fixed muffle, compressed and occurred deformation and produced the restoring force being in reverse to impulsive force, thus, this restoring force of gib head offsets part of impact force, thus reduces the impulsive force being delivered to fixed muffle and jib 12, avoids the destruction of the steel structure to jib 12.
In above-mentioned detailed description of the invention, slide shaft 161 can arrange suitable structure so that apply application force to elastic component, preferably, slide shaft 161 can be provided with radial protrusion, elastic component is set on slide shaft 161, radial protrusion and slide shaft 161 associated movement and can apply pressure to elastic component ordinatedly with fixed muffle.It can thus be appreciated that under the effect of extraneous impulsive force, slide shaft 161 slides along the axial direction of fixed muffle, and apply application force by radial protrusion to elastic component, therefore, under the cooperation of radial protrusion and fixed muffle, elastic component is compressed, and produces restoring force.
