Abstract
The utility model aims at providing a crucible lifting tool for a polycrystal ingot furnace. The crucible lifting tool is characterized by comprising four cross-distributed supports, each support is connected with a lifting arm, a central shaft is positioned at the junction position of the four supports, a lifting ring is arranged at the top end of the central shaft, a cam disk is sleeved on the central shaft, four eccentric grooves are arranged on the cam disk, one ends of connection rods are connected with the lifting arms through fork heads, the other ends of the connection rods are installed in the eccentric grooves through fork heads, and a handle is positioned on the cam disk. The crucible lifting tool for the polycrystal ingot furnace is simple and reasonable in structure, convenient and safe to operate and especially suitable for specific environments of high temperature furnace hearths.
Description
Technical field
The utility model relates to a kind of polycrystalline ingot furnace crucible hanger.
Background technology
Polycrystalline ingot furnace is that the silicon raw material of plumbago crucible and the inside lifting is put in the polysilicon burner hearth by the crucible hanger major function, plumbago crucible and silicon ingot is taken out to a kind of lifting tool of burner hearth after silicon material melting crystal again.The crucible hanger used in the market is the design comparison heaviness mostly, complex operation, and security is low.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of polycrystalline ingot furnace crucible hanger is provided.
Concrete scheme is as follows:
A kind of polycrystalline ingot furnace crucible hanger is characterized in that: comprise four supports of cross distribution, each support connects an arm; Four support intersections are provided with central shaft, and the central shaft top is suspension ring, and sheathed cam plate on central shaft is offered four eccentric grooves on cam plate, and connecting rod one end connects arm by jaw, and the other end is arranged in eccentric groove by jaw, and cam plate is provided with handle.
Preferably, described support is connected by bearing pin with arm.
Preferably, described arm is welded into an integral body by upper and lower two stainless steel plates, and upper end is connected with support by bearing pin.
Beneficial effect:
Polycrystalline ingot furnace of the present utility model is simple and reasonable, easy to operate and safe with crucible hanger, is particularly suitable for using in the specific environment of high-temperature burner hearth.
The accompanying drawing explanation
Fig. 1 is the work schematic diagram of polycrystalline ingot furnace of the present utility model with crucible hanger.
Wherein: 1-arm, 2-jaw, 3-handle, 4-cam plate, 5-central shaft, 6-connecting rod, 7-support, 8-bearing pin.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
A kind of polycrystalline ingot furnace crucible hanger is characterized in that: comprise four supports 7 of cross distribution, each support 7 connects an arm 1; Four support 7 intersections are provided with central shaft 5, and central shaft 5 tops are suspension ring, sheathed cam plate 4 on central shaft 5, offer four eccentric grooves on cam plate 4, connecting rod 6 one ends connect arm 1 by jaw 2, and the other end is arranged in eccentric groove by jaw 2, and cam plate 4 is provided with handle 3.Described support 7 is connected by bearing pin 8 with arm 1.Described arm 1 is welded into an integral body by upper and lower two stainless steel plates, and upper end is connected with support 7 by bearing pin 8.
Whole device is to utilize the principle of cam plate 4 and lever to complete a series of action, when pulling handle 3 counterclockwise, cam plate 4 will rotate around central shaft 5, have four eccentric grooves on cam plate 4 and can produce radial displacement, the distance that will move radially by four connecting rods 6 and jaw 2 is delivered to the upper end of four arms 1, arm 1 and bearing pin 8 form a lever, according to lever principle, the lower end of four arms 1 can outwards be opened simultaneously, arm 1 lower end inward collapsible simultaneously when in the other direction pulling handle 3, catch on the bottom of plumbago crucible, by weight handling equipment, just plumbago crucible can be mentioned together with the silicon material of the inside, pinning four arms 1 by the weight of plumbago crucible and silicon material self after mentioning can outwards not open voluntarily.
Finally, it is also to be noted that, what more than enumerate is only specific embodiment of the utility model, and obviously, the utility model is not limited to above examples of implementation, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model, all should think protection domain of the present utility model.
