Abstract
The utility model relates to a mechanical lifting apparatus, and the utility model is composed of an electromotor, a lifting and lowering sleeve barrel, a guide rod, a leading screw, an intermediate gear, a gear shaft and a retarding mechanism with planetary gear drive with small teeth difference, wherein, the lifting and lowering sleeve barrel is connected with lifting and lowering nuts in a way of interference fit, and the guide rod is fixedly connected with the outer housing body through screw threads. The leading screw is matched with the outer housing body through a bearing, the gear shaft is matched with the outer housing body through another bearing, and the retarding mechanism with planetary gear drive with small teeth difference which is composed of a planetary gear, an inner gear ring and an eccentric shaft is used for decelerating, changing direction and driving the gear shaft to rotate. Compared with a jack, the work efficiency of the utility model is three to five times of the work efficiency of the jack.
Description
The utility model relates to the lifting device of a kind of mechanical type lifting device, particularly automobile and construction machinery and equipment use in the repair and maintenance maintenance.
At present, in the process of maintenance and maintenance automobile and construction machinery and equipment, the general concrete position that all needs according to maintenance and maintaining, with vehicle on request lifting get up, present, comprise medium and small professional factory, generally adopt jack as lifting equipment, jack needs manual operation, and the labour intensity that works together is very big, dangerous, inefficiency.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art a kind of high efficiency is provided, and is safe and reliable, the mechanical type lifting device that saves labor.
The purpose of this utility model is achieved in that it comprises motor, and its jacking sleeve is connected with the mode of lifting nut by interference fit.Guide rod through threaded and body skin are fastenedly connected.Leading screw is combined together by bearing and body skin.Counter gear shaft is combined together by bearing and body skin.Gear wheel shaft also is combined together by bearing and body skin.Planetary wheel is combined together by bearing and eccentric shaft, and is connected with gear wheel shaft by coupler.Internally toothed annulus is fastenedly connected by bolt and body skin.Eccentric shaft is connected with motor by spline.
The purpose of this utility model can also reach by following technical measures: guide rod is set to two.Have gear on the leading screw.
Compared to existing technology, the utlity model has following advantage:
1, high efficiency.Compare with " jack " lifting equipment of present employing, can improve work efficiency 3-5 doubly.
2, simple in structure.It constitutes small teeth number difference planet gear transmission speed reducer structure with internally toothed annulus, planetary wheel, coupler, and simplicity of design is reasonable.
3, safety of operation saves labor.Whole job procedure has greatly reduced labour intensity by mechanical drive, and safety hazard is controlled to be minimum.
The explanation of accompanying drawing drawing:
Accompanying drawing is the utility model structural representation.
Embodiment describes the utility model in detail below in conjunction with accompanying drawing.
The utility model is to replace the lifting device that jack is applied to automobile, construction machinery and equipment maintenance maintenance usefulness.Its all parts all adopt metallic material.Its jacking sleeve (1) is packed in the housing (2), adopts the mode of interference fit to link together with lifting nut (4), and jacking sleeve (1) adopts free-running fit with body skin (2).Guide rod is two, and two guide rods (3,13) are arranged side by side in housing, lay respectively at the outside of jacking sleeve (1).Guide rod (3,13) all adopts screw threads for fastening to be connected with shell (2), adopts free-running fit with lifting nut (4).Lifting nut (4) can slide up and down along guide rod (3) and guide rod (13).Leading screw has gear on (5), is positioned at jacking sleeve (1).Intermediate gear (6) is combined together by axle and body skin (2).Gear wheel shaft (8) also is combined together by bearing and body skin (2).Internally toothed annulus (9), planetary wheel (10), coupler (7) are formed " small teeth number difference planet gear transmission speed reducer structure ".Internally toothed annulus (9) adopts bolted to be connected with body skin (2), and planetary wheel (10) is combined together by bearing and eccentric shaft (11), and eccentric shaft (11) is combined together by bearing with body skin (2).Eccentric shaft (11) is connected with electrical motor (12) by spline.
Principle of work of the present utility model is:
When electrical motor (12) drives eccentric shaft (11) when clockwise rotating, by by internally toothed annulus (9), " small teeth number difference planet gear transmission speed reducer structure " deceleration break-in that planetary wheel (10) coupler (7) is formed, make gear wheel shaft (8) low speed left-hand revolution, gear wheel shaft (8) drives leading screw (5) clickwise by intermediate gear (6) again, lifting nut (4) drives jacking sleeve (1) and rises, with the weight lifting.
When electrical motor (12) drives eccentric shaft (11) left-hand revolution, by " small teeth number difference planet gear transmission speed reducer structure " deceleration break-in, gear wheel shaft (8) low speed clickwise, and by intermediate gear (6) drive leading screw (5) left-hand revolution, make lifting nut (4) drive jacking sleeve (1) and descend, weight descends.
Electrical motor of the present utility model (12) adopts the coventional type electrical motor, and horsepower output is 1.5KW.
