Problems solved by technology

Frequent application of active drive force is not good for the drive mechanism
In the case of absence or failure of the driving power unit, the transfer of one phase of the cam to another becomes difficult and infeasible

Abstract

The invention provides a cam hoisting mechanism. The cam hoisting mechanism is used for controlling the hoisting of an object (9) and comprises a rack (1), an eccentric wheel (2), a locking pin (3), an elastic push pin (4) and a limiting column (5), wherein the eccentric wheel (2) is totally in a circular shape and is eccentrically provided with a driving rotating shaft (21); when the circle center of the circular shape is located above the driving rotating shaft (21) and a vertical relation is formed between the circular shape and the driving rotating shaft (21), the eccentric wheel (2) lifts the object (9) to a high position; a locking hole (23) which is concave inwards in the radial direction is further formed in the circumference of the eccentric wheel (2) and is matched with the upper end of the locking pin (3); and when the eccentric wheel (2) lifts the object (9) to the high position, the locking hole (23) is formed under the driving rotating shaft (21) and a vertical relation is formed between the locking hole (23) and the driving rotating shaft (21).

Description

[0001] technical field [0002] The present application relates to a lifting mechanism, in particular to a cam lifting mechanism. [0003] Background technique [0004] The cam mechanism is a high-level mechanism composed of three basic components: the cam, the follower and the frame. The cam is a component with a curved profile or a groove, generally a driving part, which performs constant-speed rotary motion or reciprocating linear motion. [0005] The component that is in contact with the cam profile, transmits power and realizes a predetermined law of motion, generally performs reciprocating linear motion or swings, and is called a follower, or an object that is lifted. [0006] The basic feature of the cam mechanism in application is that it can make the follower obtain more complex motion laws. Because the motion law of the follower depends on the cam profile curve, so in application, it is enough to design the cam profile curve according to the motion law of the...
