Abstract
The utility model relates to a crucible hoisting tool which comprises a limiting support and slings, wherein the slings are mounted on the limiting support in a penetrating mode. The limiting support comprises two longitudinal limiting arms and two limiting rings, wherein the longitudinal limiting arms are distributed along the circumferential direction of a crucible, and the limiting rings are connected between the two longitudinal limiting arms. The lower end of each longitudinal limiting arm is provided with a transverse limiting arm, and the transverse limiting arms extend towards two sides. Thread passing holes are formed in the transverse limiting arms and the limiting rings, and the slings penetrate through the thread passing holes. Through the arrangement of the longitudinal limiting arms, the transverse limiting arms and the thread passing holes, and the slings penetrate through the thread passing holes, the slings are led in from a narrow gap between a sapphire crystal growing furnace and the crucible. The distance between every two thread passing holes in the limiting rings is longer than the distance between the two thread passing holes in each transverse limiting arm, and therefore the slings can extend into the bottom of the crucible when being pulled.
Description
Technical field
The utility model relates to a kind of crucible hoisting instrument, particularly sapphire crucible lifting tool.
Background technology
Need in the production process of sapphire crystal crucible is taken out in the sapphire crystal growth stove, but crucible is heavier, this moment, crucible had high temperature to 300 degree, crucible is not provided with the device for lifting, and only having tiny gap around crucible in sapphire crystal growing furnace, hand can not stretch into.The lifting that is provided with crucible is more loaded down with trivial details, and efficient is not high.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of simple to operation, can be quick, and the crucible hoisting instrument of the lifting sapphire crucible of safety.
The utility model solves its technical problem and adopts following technical scheme: a kind of crucible hoisting instrument, comprise limiting bracket and the hoist cable that is installed on limiting bracket, described limiting bracket comprises along circumferential two the longitudinal spacing arms that distribute of crucible and is connected in two spacing rings between the longitudinal spacing arm, the lower end of described longitudinal spacing arm is provided with the cross spacing arm that extends to both sides, be equipped with cable-through hole on described cross spacing arm and spacing ring, described hoist cable passes described cable-through hole.
Further technical scheme: described two longitudinal spacing arm tops connect by connecting arm.
Further technical scheme: described longitudinal spacing arm or spacing ring are provided with the catch that offsets with crucible.
Further technical scheme: described catch is provided with stiffening web.
Further technical scheme: the spacing of described spacing ring two cable-through holes is greater than the spacing of cross spacing arm two cable-through holes.
Further technical scheme: described cross spacing arm forms and circumferentially extends arc along crucible.
The beneficial effects of the utility model are: thus adopt said structure that hoist cable is introduced among the close gap of sapphire crystal growing furnace and crucible by support, and can stretch into crucible bottom, the transfer hoist cable crucible of slinging.Can fast lifting appliance and crucible be located.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the assembling schematic diagram of crucible hoisting instrument and crucible.
Embodiment
with reference to figure 1, Fig. 2, shown in a kind of crucible hoisting instrument, comprise limiting bracket 1 and the hoist cable 2 that is installed on limiting bracket, described limiting bracket 1 comprises along circumferential two of distributing of crucible 7 and is the longitudinal spacing arms 11 of 180 degree and is connected in two spacing rings 12 between longitudinal spacing arm 11, the lower end of described longitudinal spacing arm 11 is provided with the cross spacing arm 13 that extends to both sides, the two ends of described cross spacing arm 13 arrange the first cable-through hole 14, spacing ring 12 is provided with four symmetries at the second cable-through hole 15 of longitudinal spacing arm 11 both sides, described hoist cable is staggered passes cable-through hole on longitudinal spacing arm both sides, and must not pass successively with the cable-through hole on a longitudinal spacing arm.
Described the first cable-through hole 14 and the second cable-through hole 15 are manhole, if spacing ring 12 or cross spacing wall 13 are the metal foil piece, can the through hole be set at need and set in advance projection 14, then through hole is set on projection.
Described two longitudinal spacing arm 11 tops connect by connecting arm 3.
All be provided with the catch 4 that offsets with crucible 7 on described two longitudinal spacing arm 11 inwalls, catch 4 is less than the height of crucible 7 to the distance of longitudinal spacing arm 11 bottom surfaces, guarantee that longitudinal spacing arm bottom surface and crucible bottom surface are at regular intervals, and hoist cable 2 can stretch under crucible; Described catch 4 also can be arranged on spacing ring 12.
Shown in catch 4 upper surfaces and 11, longitudinal spacing arm be provided with stiffening web 5; Block is suspended from inwall, easily by bending, or even fractures when being subject to larger external force, and the stiffening web of setting can strengthen the intensity of baffle plate.Described stiffening web also can be located at the baffle plate bottom surface.
The spacing of described spacing ring the 12 two the second cable-through holes after adopting this structure, pulls hoist cable 2 greater than the spacing of cross spacing arm the 13 two the first cable-through holes, and hoist cable can stretch under crucible 7, and the hoist cable tensioning is placed on the crucible bottom surface.
Described cross spacing arm 13 forms along crucible 7 and circumferentially extends arc, and the circular clearance coupling of arc and sapphire crystal growing furnace and crucible guarantees that the cross spacing wall inserts from the gap.
The tail end of described hoist cable 2 is connected on suspension ring 6, by suspension ring, lifting tool is hung on weight handling equipment, and suspension ring can better keep the left-right symmetry of hoist cable, keeps the balance of lifting.
Those skilled in the art can make various changes and distortion to the utility model after knowing principle of the present utility model, only otherwise break away from spirit of the present utility model, all should belong to the defined scope of the utility model claims.
