Lifting device for cylinder cover of biological tissue dehydrator

Abstract

The invention relates to the technical field of biological tissue dehydrators, in particular to a lifting device for a cylinder cover of a biological tissue dehydrator, which includes a base. A spiralsleeve and a guiding sleeve are fixed on the upper surface of the base. A screw is threadably connected to the inner wall of the spiral sleeve. A hand wheel and a driven bevel gear are fixed on the outer wall of the screw. The driven bevel gear is externally meshed with a driving bevel gear. The driven bevel gear is fixed to an output shaft of a driving motor. A sleeve is provided on the top endof the screw. A support plate is fixed on the top end of the sleeve. A lifting arm is fixed on the left end of the support plate. The lower surface of the lifting arm is embedded with an electromagnet. The cylinder cover is magnetically attracted to the lower end of the electromagnet. A hook is fixed on the lower surface of the cylinder cover. A nacelle is hooked on the lower end of the hook. Thelifting device for the cylinder cover of the biological tissue dehydrator solves the problems of complicated structure, poor stability, inconvenience in controlling the lifting and the lowering of thecylinder cover, and also solves the problem that the cylinder cover cannot be manually controlled when the power is cut off.

Description

technical field [0001] The invention relates to the technical field of a biological tissue dehydrator, in particular to a lifting device for a cylinder head of a biological tissue dehydrator. Background technique [0002] The biological tissue dehydrator includes a boom and a hanging basket, and the boom is connected to the hanging basket; the biological tissue to be processed is placed in the hanging basket, and under the control of the control device according to the set program, the hanging basket is suspended by the boom. On the running track, the hanging baskets are gradually placed into various soaking tanks filled with various soaking liquids and paraffin for soaking dehydration and embedding paraffin, until the dehydration process of the entire biological tissue is completed; in order to prevent soaking tanks The liquid volatilizes, the top of the hanging basket is provided with a cylinder cover, the boom is connected with the upper part of the cylinder cover, the up...
