Abstract
The utility model relates to a tool for taking out a heater in a Czochralski crystal grower. The tool comprises two heater lifting parts which are arranged oppositely. The tool is characterized in that each heater lifting part comprises a drawing frame and a bottom support, wherein each bottom support is composed of a bottom plate which is arc-shaped wholly and a clamping support; each clamping support is fixedly arranged on the peripheral circular arc of the bottom plate and an included angle which is more than 90 degrees is formed between each clamping support and each bottom plate; each drawing frame is in a step-shaped framework structure with the sealed upper end; and the bottom end of each drawing frame is fixedly arranged on the bottom plate of each bottom support. The tool has the beneficial effects that the two drawing frames and the two arc-shaped bottom supports, which are arranged oppositely, are designed, the bottom supports are inserted into the bottom of the heater and two workers respectively use one drawing frame to lift and take out the heater, so that the taking-out work of the heater is finished conveniently; and the damages to the heater are avoided, the working efficiency is improved and the production cost is reduced.
Description
Technical field
The utility model relates to a kind of withdrawing device of single crystal furnace heater, particularly a kind of frock of taking out well heater in czochralski crystal growing furnace.
Background technology
At present, the price of single crystal furnace heater is generally more expensive, unit price is all more than 20,000, and weight is larger, all more than 50KG, and the sidewall thickness of heating zone part is thinner, when maintain and replace, be accidentally just easy to damage, so caused very large inconvenience to surfaceman when changing well heater.
Utility model content
The purpose of this utility model is to provide a kind of simple in structure, easy and simple to handle for taking out the frock of czochralski crystal growing furnace well heater.
In order to complete above-mentioned purpose, the technical solution adopted in the utility model is:
A kind of frock of taking out well heater in czochralski crystal growing furnace, comprise two well heater lifting pieces that are oppositely arranged, described well heater lifting piece comprises extraction frame and collet, base plate and Kato that collet is arc by integral body form, Kato is fixed on the periphery circular arc of base plate and is with base plate the angle that is greater than 90 °, the stepped appearance skeleton construction that described extraction frame is upper end closed, the bottom of extracting frame is fixed on the base plate of collet.
The top of described extraction frame is provided with support bar, and the two ends of support bar are fixed in the skeleton construction of extracting frame.
The central angle of described collet is more than or equal to 30 ° and be less than or equal to 60 °.
The angle of the step shape part of described extraction frame is at least 90 °.
The beneficial effects of the utility model are: owing to having designed two extraction framves that are oppositely arranged and the collet of arc, collet can be inserted to the bottom of well heater, by two workmans, with one, extract frame respectively again well heater is promoted to taking-up simultaneously, conveniently completed the taking-up work of well heater, avoided causing the damage of well heater, improved working efficiency and reduced production cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1, extract frame, 2, base plate, 3, Kato, 4, support bar.
Embodiment
The utility model is a kind of frock of taking out well heater in czochralski crystal growing furnace, owing to having designed two extraction framves that are oppositely arranged and the collet of arc, collet can be inserted to the bottom of well heater, by two workmans, with one, extract frame respectively again well heater is promoted to taking-up simultaneously, conveniently completed the taking-up work of well heater, avoided causing the damage of well heater, improved working efficiency and reduced production cost.
Below in conjunction with accompanying drawing, the utility model is described further.
Specific embodiment, as shown in Figure 1, a kind of frock of taking out well heater in czochralski crystal growing furnace, comprise two well heater lifting pieces that are oppositely arranged, described well heater lifting piece comprises extraction frame 1 and collet, base plate 2 and Kato 3 that collet is arc by integral body form, for the ease of operation, the central angle of collet is set to be more than or equal to 30 ° and be less than or equal to 60 °, Kato 3 is fixed on the periphery circular arc of base plate 2 and is and is greater than the angle of 90 ° in order to well heater is fixed with base plate 2, the stepped appearance skeleton construction that described extraction frame 1 is upper end closed, lifting operation for convenience of workman is made as the angle that extracts the step shape part of frame 1 to be at least 90 °, the bottom of extracting frame 1 is fixed on the base plate 2 of collet, in order to strengthen the structural stability of extracting frame 1, on the top of extracting frame 1, be also provided with support bar 4, the two ends of support bar 4 are fixed in the skeleton construction of extracting frame 1.
In the time will taking out operation to well heater, send two workmans to operate respectively a well heater lifting piece, first collet is inserted to the bottom of well heater, so latter two workman does lifting operation to extracting frame 1 simultaneously, thereby well heater can be promoted and takes out, conveniently completed the taking-up work of well heater, avoided causing the damage of well heater, improved working efficiency and reduced production cost.
