Description
Technical field
The utility model relates to a kind of apparatus for automatically lifting, is specially a kind of apparatus for automatically lifting of noncombustibility test furnace sample, belongs to building material technical field.
Background technology
Building materials noncombustibility tester is state compulsion standard, one of equipment of the fire-retardant hierarchical test indispensability of building materials; This tester laboratory needs heating furnace temperature rise to 750 DEG C, then clamping sample drop to heating furnace center; Because furnace temp is very high, when clamping sample and decline sample, operation is just very high to security; And the requirement that sample declines drops to center within 5 seconds.
All products in the market all adopt Manual descending when sample declines; There is following problem:
1), Manual descending, add experimenter scald risk;
2), Manual descending is difficult to the position reaching standard-required in 5s that the control time reaches standard-required;
3), Manual descending is difficult to reach center accurately;
4) manual adjustments position, when temperature correction, needs to survey a temperature every 5mm, if can bother and be very easy to scald very much.
Utility model content
The technical problems to be solved in the utility model overcomes existing defect, provides a kind of apparatus for automatically lifting of noncombustibility test furnace sample, by can accomplish the control when base measuring temperature to diverse location easily to the control of motor, thus solves the problem.
For achieving the above object, the utility model provides following technical scheme: a kind of apparatus for automatically lifting of noncombustibility test furnace sample, comprises casing, and described casing top is provided with brace table, and described brace table is provided with support body; Be provided with heating furnace bottom described support body, described inside heating furnace is provided with sample frame and thermopair; Described support body side is provided with the motor of PLC control system.
Further, bottom described heating furnace with install between casing top one with the guide shell be connected bottom heating furnace.
Further, described motor is servomotor or asynchronous machine, and described motor is provided with starting position switch and emphasis position switch.
Further, described motor is fixed on support one end, and the described support other end fixes sample frame by sample frame suspension rod.
Further, an adjustable mirror is installed by regulating device in described support body top.
Compared with prior art, the beneficial effects of the utility model are: the apparatus for automatically lifting of this kind of noncombustibility test furnace sample, by can accomplish the control when base measuring temperature to diverse location easily to the control of motor, and reach assigned address in 5 seconds, avoid the risk that experimenter scalds.
