Abstract
The utility model discloses a clamp for lifting a large polycrystalline ingot casting crucible, and relates to the technical field of a polycrystalline ingot casting tool. The device comprises orthogonal beams and four pull force transforming rods in the same structure, wherein the middle parts of the pull force transforming rods are hinged at four ends of the orthogonal beams; a plurality of steel wire ropes of which the tail ends are connected to a point are arranged at the top ends the pull force transforming rods; each steel wire rope runs through pulleys which are arranged at the ends of the orthogonal beams, the pulleys are positioned on the outer sides of the four pull force transforming rods, and the lower ends of the four pull force transforming rods are provided with clamp plates. Through transforming a pull force into a clamping force and a supporting force for a crucible by utilizing the pull force transforming rods, and meanwhile, and with the adoption of the fixed pulleys, the swinging amplitude and the effect of the pull force transforming rods are enhanced; the crucible can be lifted easily by only one person, the clamp is safe and convenient, the manpower is saved, the labor amount of an operator is greatly reduced, and the clamp has very important meanings in an actual production process.
Description
Technical field
The utility model relates to the polycrystalline cast ingot technical field of tools.
Background technology
Current photovoltaic Market competition, each photovoltaic producer is all managing to reduce the production run cost, concerning the polycrystalline cast ingot this respect, large ingot has suitable advantage, but the also corresponding increase of crucible size that large ingot needs, directly make the weight of crucible increase, and this just needs more people compounding practice simultaneously, easily cause the adverse effect such as collide with, make difficulty and risk in the process of carrying crucible increase.Polycrystalline cast ingot is towards the large ingot future development of casting, silicon ingot by original 270kg to 450kg, then the 1000kg even of 900kg till now.Along with the increase of silicon ingot weight, the crucible size of use and weight also increase accordingly, make crucible increase difficulty and risk in handling process, and the crucible quality is crisp hard, once combination miss very easily collides with and causes outward appearance cracking or stealthy damage crucible.Outward appearance cracking is scrapped crucible, if stealthy damage can not check out, during for normal ingot casting, under the environment of high-temp liquid, for the leakage accident hides some dangers for, this is extremely dangerous.Existing fixture type, on the longitudinal plane of symmetry that is clipped in crucible had, because crucible is heavier, longitudinal plane of symmetry does not have the direct strong point, and during lifting, very large power effect on the whole, is easily squeezed bad crucible.Some fixture is the inner outer crucible that vises in addition, the method likely in the process of clamp the inwall to crucible cause damage, the large crucible itself used now is heavy especially, needs at least four people that crucible is lifted and is put on transport carriage.
So be badly in need of now a kind of can be safely, convenient and can not cause to crucible the large-scale crucible vertical loading tool of damage.
The utility model content
The technical problems to be solved in the utility model be to provide a kind of can be safely, convenient, save manpower, raise the efficiency and can not cause to crucible the fixture of the hoisting large-size polycrystalline cast ingot crucible of damage.
For addressing the above problem, the technical scheme that the utility model is taked is: a kind of fixture for hoisting large-size polycrystalline cast ingot crucible, it is characterized in that: comprise that " ten " word cross coupling is articulated in the identical pulling force conversion bar of four root architectures of four ends of " ten " word cross coupling with middle part, described four pulling force transform the masthead end steel rope that end is connected to any all are installed, described every steel rope is all through the pulley that is positioned at " ten " word cross coupling end, described pulley is positioned at the outside that pulling force transforms bar, and the lower end that described pulling force transforms bar is provided with clamping plate.
Preferably the end of described " ten " font cross coupling is beam column, and the beam column top is higher than the beam body, and described pulley is fixed on beam column.
Preferred described steel rope one end transforms bar by bar hole and pulling force and fixes, and the other end all is connected with hook by link.
The beneficial effect that adopts technique scheme to produce is: this stone tongs adopts the pulling force selector bar, pulling force is converted into to folder power and the Tuo Li to crucible, fixed pulley is set simultaneously, increase amplitude of fluctuation and action effect that pulling force transforms bar, only large-scale crucible need be put under fixture with fork truck, there is one man operation just crucible easily can be mentioned, and safe ready, save manpower, greatly alleviate operative employee's labor content, clamping plate used design according to the suspension centre of crucible, can firmly clamp crucible, the invention of this fixture has very positive meaning in actual production process.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
A kind of fixture for hoisting large-size polycrystalline cast ingot crucible as shown in Figure 1, it is characterized in that: comprise that " ten " word cross coupling is articulated in the identical pulling force conversion bar 7 of four root architectures of four ends of " ten " word cross coupling with middle part, described four pulling force transform bar 7 tops the steel rope 3 that end is connected to any all are installed, described every steel rope 3 is all through the pulley 4 that is positioned at " ten " word cross coupling end, described pulley 4 is positioned at the outside that pulling force transforms bar 7, and the lower end that described pulling force transforms bar 7 is provided with clamping plate 10.Pulling force transforms bar 7 and is altogether four, be hingedly fixed in respectively on four beam bodies 6 of " ten " font cross coupling, approximately be fixed on the medium position that pulling force transforms bar 7, pulling force transform bar 7 can rotating shaft 9 for basic point is rotated, the bottom of pulling force conversion bar 7 is provided with the clamping plate 10 for clamping crucible, the stress point that top is pulling force, effect lower pulling force at the top pulling force transforms bar 7 rotations, make clamping plate 10 clamp crucible, four clamping plate 10 are exerted oneself simultaneously, just crucible are clamped firmly.
The end of described " ten " font cross coupling is beam column 5, and beam column 5 tops are higher than beam body 6, and described pulley 4 is fixed on beam column 5.It is fixing that described steel rope 3 one ends transform bar 7 by bar hole 8 and pulling force, and the other end all is connected with hook 1 by link 2.Act on the steel rope 3 on pulling force conversion bar 7 tops by pulley 4, so more can transform bar 7 generation pulling force to pulling force by actv., increased the amplitude of fluctuation of pulling force conversion bar 7 simultaneously, strengthened action effect.
The beneficial effect that adopts technique scheme to produce is: this stone tongs adopts the pulling force selector bar, pulling force is converted into to folder power and the Tuo Li to crucible, fixed pulley is set simultaneously, increase amplitude of fluctuation and action effect that pulling force transforms bar, only large-scale crucible need be put under fixture with fork truck, there is one man operation just crucible easily can be mentioned, and safe ready, save manpower, greatly alleviate operative employee's labor content, clamping plate used design according to the suspension centre of crucible, can firmly clamp crucible, the invention of this fixture has very positive meaning in actual production process.
