Description
Technical field
The invention belongs to elaborate servo hoisting mechanism technical fields, are related to the discharge device technology neck of servo hoisting mechanism
Domain particularly belongs to a kind of discharge device with position memory function.
Background technique
Servo lifting mechanism is usually driven by servo motor, and servo motor drives precision speed reduction device, precision speed reduction device driving
The positive and negative Wound steel rope of reel realizes the promotion and decentralization of weight respectively, and general rope outlet direction is vertical in servo lifting mechanism
In reel rope stretching, and the rope outlet direction of only one Spatial Dimension changes, but needs in substantial portion special applications from side plate
Rope stretching is parallel to the rope stretching of reel direction, and during rope stretching, and needs a wide range of elevation angle of two spaces dimension simultaneously
The variation of degree, and it is able to achieve the discharge that wirerope is continuous, smooth, without impact and rule, steel wire can be remembered during rope stretching
The space angle position of the upper movement of rope, needing to research and develop one kind thus, special discharge device meets the demand with this.
The existing mechanism from side plate rope stretching is rarely found, typically no to have memory function to rope stretching space angle position
Mechanism also cannot achieve the variation of a wide range of rope stretching angle of two spaces dimension, in the prior art often by multiple bodies
The biggish pulley mechanism of product is converted repeatedly realizes although the rope stretching of side plate direction, this switching mechanism are able to achieve wirerope from side plate side
To rope stretching, but rope stretching angle is the variation of a Spatial Dimension, and can not remember wirerope when wirerope is unloaded in short-term
Space angle position, and volume is big, heavy, maintenance is inconvenient, cost of manufacture is high, is unable to satisfy the packaging and sky of compact
Fortune demand.
Summary of the invention
Servo lifting mechanism is unable to satisfy from side plate rope stretching for discharge device in the prior art, it can not two spaces dimension
A wide range of adjusting rope stretching angle, and rope stretching position and direction can not be remembered, and structure is complicated, performance is unstable for discharge device
It is fixed, manufacturing cost is higher etc., and problems, the present invention provide a kind of discharge device with position memory function, purpose exists
In: a kind of discharge device of special construction principle is provided, is thoroughly solved the above problems.
The technical solution adopted by the invention is as follows:
A kind of discharge device with position memory function, comprising: the side of rope stretching component, the rope stretching component is provided with
