Abstract
The utility model discloses a silicon rod lifting clamp which comprises an upper clamping piece, a lower clamping piece, and a plurality of stand columns used for connecting the upper clamping piece and the lower clamping piece, wherein each of the upper clamping piece and the lower clamping piece is formed by buckling of two semicircular clamp plates; lifting rings are arranged at the tops of the two semicircular clamp plates of the upper clamping piece; the stand columns are vertical to each circular ring formed by buckling of every two semicircular clamp plates and are uniformly distributed on the circular rings. According to the utility model, the two pairs of semicircular clamp plates are utilized to form a cylindrical clamp, so that a silicon single crystal rod falling off accidentally in a single crystal furnace can be taken out rapidly and safely; the stand columns ensure that the gravity center of the silicon rod in the lifting process is vertical downward, so that the silicon rod can be lifted vertically and danger is avoided; manpower support is not required when the silicon rod is lifted, so that the accident about accidental scald of personnel by the high-temperature silicon rod can be avoided, and production and safety are ensured.
Description
Technical field
The utility model belongs to silicon single crystal rod lift technique field, is specifically related to a kind of silicon single crystal rod lifting clamp.
Background technology
At present, most of single crystal growing furnaces all inevitably can crash into thermal field of single crystal furnace inside because silicon rod artificial or that the reasons such as seed crystal itself and thin neck cause comes off in the silicon single crystal rod production process, this moment is comparatively uniform and smooth because of the appearance of silicon rod own, and temperature is higher, the heavier difficult taking-up of weight.The measure that this situation of common reply is taked has: (1), when silicon rod is longer, utilizes the waste steel wire rope to be wound around the silicon rod surface, when steel wire rope head is produced with single crystal growing furnace, promotes silicon rod wireline used and is connected, and utilizes the lifting mechanism of single crystal growing furnace itself slowly to take out; (2) silicon rod more in short-term, manually takes out it with high-temperature-resistant glove.
But all there is hidden danger in two kinds of methods: the former can not guarantee the silicon rod center of gravity vertically downward because of the wireline that is wound around (1), and be wound around inequality and cause silicon rod unbalance stress while promoting, while silicon rod smooth surface, in lifting process, the accidents such as the wireline lie low suddenly, be wound around come off suddenly can occur because of crank in silicon rod, cause the secondary damage of thermal field of single crystal furnace and silicon rod itself, again cause heavy losses; (2) latter is too high because of the silicon rod self-temperature, silicon rod can't be down to normal temperature in short-term, the balance that relies on the manpower holder to hold up the bonding crystalline silicon rod, in lifting, the silicon rod unbalance stress, easily cause danger, even if silicon rod length is shorter, due to excess Temperature, during with artificial taking-up, likely cause scald, if wait silicon rod to be down to normal temperature, can cause the loss of time.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of fixture safe, that the silicon single crystal rod in single crystal growing furnace takes out by accidental falling fast.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of silicon rod lifting clamp comprises holder, lower holder and connects many root posts of going up holder and lower holder; Described upper holder and lower holder fasten and form by two semicircle clamping plate, and the top of two semicircle clamping plate of upper holder respectively is provided with suspension ring; Described many root posts are vertical and uniform on annulus with the annulus that two semicircle clamping plate fasten formation.
Wherein, two opening ends of described semicircle clamping plate respectively are provided with a journal stirrup, and journal stirrup is provided with for bolted through hole.
Wherein, described semicircle clamping plate and column are made by stainless material.
Wherein, on the medial surface of two of described lower holder semicircle clamping plate, respectively be provided with a semicircular high temperature resistant pad.
Wherein, described high temperature resistant pad is Tetrafluoro spacer.
The beneficial effect that adopts technique scheme to produce is: the utility model is simple in structure, easy to use, the silicon single crystal rod of taking-up accidental falling in single crystal growing furnace that can be quick, safe, compared with prior art: (1) utilizes the semicircle clamping plate in two pairs of up and down to form cylindrical fixture, can guarantee in lifting process that the silicon rod center of gravity vertically downward, make the silicon rod vertical-lift, avoid causing danger; (2) by the high temperature resistant pad of liner of lower holder, play effect anti-skidding, slip-off preventing, effectively avoid the silicon rod secondary to fall; (3) the up and down holder utilizes screw to carry out fastening, simple to operation to two semicircle clamping plate; (4) when silicon rod promotes, do not need the manpower holder to hold up, avoided personnel to scald and have an accident because silicon rod high temperature is unexpected, production and safety are protected.The utility model applied range, the lifting that not only can be applied to silicon single crystal rod also can be used for the lifting of other cylindrical objects.
