Traction sheave friction hoisting device generally partly is made up of drive motors, deceleration device, traction sheave, rope press device, check mechanism, housing etc., its operating principle is: drive motors is given traction sheave by the deceleration device transferring power, traction sheave is owing to obtain enough frictional force between the effect of rope press device and wire rope, the effect of taking this frictional force drives the lifting of hanging basket basket body.
Because the lifter of aerial work basket generally is located in the basket body and follows the basket body and moves up and down, therefore, the volume, the weight that how to reduce lifter just become the key issue of lifter design.Except that motor is that standard is purchased the part, deceleration device and other parts all are not suitable for the employing standard and purchase part, wherein deceleration device is accounting for the largest percentage aspect volume, the weight, therefore how reasonably to select form of structure for use, reasonably arrange that the position between each parts concerns, most important in the design of lifter.Usual way is that some part of general reducer is made an amendment to adapt to the characteristics of lifter, and the deceleration device of aerial work basket lifter mainly contains following several form of structure at present:
1. roller gear slows down: its advantage is that efficient is higher, handling ease, cost are lower, the position can be arranged etc. flexibly between each part, but because the gear reduction single-stage driving is smaller, therefore to reach the desired resultant gear ratio of lifter (selecting four-stage motor for use generally between 120 to 160), then deceleration device progression is more, and structure is also complicated thereupon.
2. worm and gear slows down: be that applicating history is the longest, the most a kind of form of range of application, its advantage be simple in structure, gearratio big, can self-locking, processing is more or less freely, cost is lower etc., its shortcoming is that volume and weight are bigger, efficient is low, the result causes lifter integral body relatively heavier, and effectively lifting force is relatively low.
3. harmonic gear slows down: the application on the basket of work lifter aloft is the new technology that development in recent years goes out.Harmonic gear slows down and generally is applied to fields such as aviation, communication, robot, its advantage is that gearratio is big, simple in structure, volume is little, in light weight, but the elasticity flexbile gear of the firm wheel of internal tooth, oval-shaped harmonic oscillator, band external tooth (promptly with) processing and manufacturing all needs special installation and technology because three major parts that harmonic gear slows down, therefore, its cost is higher, and quality is wayward.Can as for adapting to the harsh environment in building site, check needs time.
4. other types: except that above several principal modes, also have the minority type to use other types such as few tooth difference decelerations, differential planetary deceleration, all have shortcomings such as element precision requirement height, process and assemble difficulty are big, so be difficult to obtain practical application widely.
The purpose of this utility model just provides a kind of lifter of using novel slowing-down structure, compares with above prior art, and structure obtains simplifying and realizing easily, and can reduce cost, and is convenient to apply in practice.
For achieving the above object, the utility model adopts the cycloidal-pin wheel slowing-down structure, efferent in the standard type cycloidal-pin wheel reducer (being the bearing pin dish) is fixed on the lifter housing, and with its pin wheel housing as efferent, traction sheave and pin wheel housing combine as a whole by bolt, pin wheel housing drives the traction sheave running, with this as the climb power of load cable of friction.
Advantages such as the cycloidal-pin wheel ways of deceleration has compact conformation, gearratio is big, efficient is high, impact resistance is strong, technology maturation, cost are lower are used very extensively at present in each field, and manufacturer and supporting producer are numerous.Adopt the cycloidal-pin wheel ways of deceleration aloft in the design of basket of work lifter, can make the lifter compact overall structure reasonable, volume and weight saving also can adapt to the building site bad working environment, all are very suitable from every side therefore.
It below is the drawing explanation of accompanying drawing.
