For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of single crystal growing furnace lifting material snubber, it is characterized in that comprising three web plates be arranged in parallel, and the carrying pull bar that three web plates are connected as a single entity and union lever, three web plates are respectively upper plate, middle plate and lower plate, carrying pull bar is through upper plate, and fix with middle plate, union lever is two or more, be distributed in around carrying pull bar, union lever is through middle plate, and the two ends up and down of union lever are fixed with upper plate and lower plate respectively, elastic buffering mechanism is provided with between upper plate and middle plate.
Be further qualified said structure, described elastically damping device is set to cylindrical spring, and described spring housing is located on carrying pull bar, and the two ends of spring contact with middle plate with upper plate, and spring is in compressed state.
Be further qualified said structure, described union lever is four, its smooth surface, and middle panel edges is distributed with the aperture corresponding with union lever, and union lever is through aperture, and middle plate slides up and down along union lever.
Be further qualified said structure, the central position of described upper plate is provided with circular hole, and carrying pull bar is through circular hole, and upper plate can slide up and down along carrying pull bar.
Be further qualified said structure, the upper end of described carrying pull bar is fixed with upper lift ring, is provided with lower lift ring in the central position of lower plate lower surface, and the coupling end of described lower lift ring through lower plate, and is fixed in lower plate by nut.
The beneficial effect adopting technique scheme to produce is; The web plate that the utility model utilizes three pieces to be arranged in parallel coordinates compressible spring, form the connection mechanism with pooling feature, be arranged between cantilever and bin, for the lifting of single crystal growing furnace raw material, under the prerequisite increasing lifting amount, effectively can ensure the stability of hanging device, thus reduce the casualty ratio of accidents of crucible; The utility model each several part adopts welding process, the surface finish of union lever and carrying pull bar is smooth, web plate and union lever, carry relatively sliding between pull bar time, reduce friction, effectively improve the utilization ratio of spring slow releasing energy, make weight Slow loading when lifting heavy, slowly promote; Whole apparatus structure is simple, and cost is low, and result of use is good, can be widely used in the heavy lift under case of heavy load.

Embodiment
1 and 2 is known with reference to the accompanying drawings, the utility model is specifically related to a kind of single crystal growing furnace lifting material snubber, its structure specifically comprises three web plates be arranged in parallel, and the carrying pull bar 6 that three web plates are connected as a single entity and union lever 8, circular steel plate consistent sized by three web plates, be called as upper plate 7, middle plate 3 and lower plate 4, carrying pull bar 6 and union lever 8 are cylindrical bar, carrying pull bar 6 is through upper plate 7, and be welded and fixed with the upper surface of middle plate 3, union lever 8 is four, its smooth surface, be distributed in around carrying pull bar 6, union lever 8 is through middle plate 3, and the two ends up and down of union lever 8 are welded and fixed with upper plate 7 and lower plate 4 respectively.Elastic buffering mechanism is provided with between upper plate 7 and middle plate 3.When elastic buffering mechanism compresses under material gravity effect, carrying pull bar 6 pulls middle plate 3, and middle plate 3 is slided along union lever 8 and upper plate along carrying pull bar 6 simultaneously, and whole device elongates, elastic buffering mechanism storage power.
Elastic buffering mechanism Main Function is that the gravitional force of material is stored, and then slow release, realizes pooling feature, and its structure can be cylindrical spring, also can adopt the cylinder with pressure or oil cylinder.Adopt spring cost lower, spring 2 is sheathed on carrying pull bar 6, and the two ends of spring 2 contact with middle plate 3 with upper plate 7, and spring 2 is in compressed state.
In this use is novel, middle plate 3 marginal distribution has the aperture corresponding with union lever 8, and union lever 8, through aperture, leaves gap between aperture and union lever 8, middle plate 3 can be made to slide along union lever 8.The central position of upper plate 7 is provided with circular hole, and carrying pull bar 6, through circular hole, leaves gap between circular hole and carrying pull bar 6, thus ensures that upper plate 7 can slide up and down along carrying pull bar 6.
In addition, in order to easy to connect, be fixed with upper lift ring 1, be provided with lower lift ring 5 in the central position of lower plate 4 in the upper end of carrying pull bar 6, the coupling end of lower lift ring 5 through lower plate 4, and is fixed in lower plate 4 by nut.Upper lower lift ring connecting steel wire ropes, upper end is connected with cantilever 10, and lower end is connected with bin 11, as shown in Figure 3.
This uses novel principle of work: when upper lift ring 1 promotes, and owing to having speed upwards, make it plate 3 compression spring 2 in drive and promote, now can drive the 90-95% of below weight of material, now downside weight is not all mentioned; Spring 2 is compressed, and makes material slowly increase, and when central plate 3 is compressed to the limit, union lever 8 starts to have an effect, and union lever 8 uses cantilever 10 strength the weight of residue 5-10% to be mentioned.Like this by the process that this device cushions, make to play buffering in its lifting process, the weight of material loading time extends, and plays a protective role to the crucible on below bin 11.
