Abstract
The utility model disclosed a ratchet hoist crane for retarding mechanism proposal that fixed connections are arranged between the positive speed gearbox and Clapboard One, Two and Three. The motor output gear is joggled to the first reduction driven gear fixed on the left of the two-stage reducer, which is supported by Clapboard One and the body wall through three clapboards. On the right of the two-stage reducer is a double reduction driving gear, which is joggled to the double reduction driven gear fixed on the three-stage reducer. The triple reduction driving gear is supported by Clapboard Three and the body wall, joggled to the triple reduction driven gear fixed on the sleeve pipe. The sleeve pipe is arranged on the two-stage reducer which is supported by Clapboard Two and Three. A hoisting sprocket wheel is arranged on the sleeve pipe between Clapboard Two and Three, and the calibrated chain and the axle are arranged between Clapboard One and Two.
Description
Affiliated technical field:
The utility model relates to a kind of hoisting and hanging facility, especially loop chain hoist crane speed reduction gearing.
Background technology:
In the prior art, technique known is that the applicant applies for and is No. 02213729.7 patent by the patent No. that State Intellectual Property Office is authorized, this patent disclosure a kind of technical scheme of Electric Chain Blocks, the structure of this scheme can make the volume of hoist crane littler, more attractive in appearance, and its manufacturing cost is also lower, but, this structure, for lifting more than 20 tons the large-tonnage weight just seem not too and to adapt to that this is the existing in prior technology weak point.
Summary of the invention:
The utility model is exactly at the existing in prior technology deficiency, and provide a kind of loop chain hoist crane speed reduction gearing technical scheme, dividing plate is installed in this scheme employing additional in deceleration box makes the rotating shaft of deboost axle and chain hoist wheel support by dividing plate, increased the ability of load-bearing, in addition, increased a pleasure boat again, loop chain is increased, improve lifting strength, made it to be fit to lifting large-tonnage weight.
This programme is realized by following technical measures: include motor and with motor bonded assembly deceleration box and deceleration box in chain hoist wheel, the characteristics of this programme are to have dividing plate one, dividing plate two and dividing plate three to captive joint with deceleration box in deceleration box; The motor of described motor goes out shaft gear and the engagement of one-level deceleration ring gear, one-level deceleration ring gear is fixed on the left end of the double reduction axle of motor axis below, this double reduction axle passes dividing plate one, dividing plate two and dividing plate three and by dividing plate one and right side drop-gear box body wall bearings, right-hand member at the double reduction axle is fixed with the double reduction driving gear, this double reduction driving gear and the engagement of double reduction ring gear, the double reduction ring gear is fixed on three grades of deboost axles, three grades of deboost axles are then by dividing plate three and right side drop-gear box body wall bearings, on three grades of deboost axles, also be fixed with three grades of deceleration driving gears and three grades of deceleration ring gear engagements, three grades of deceleration ring gears are fixed on the axle sleeve, this axle sleeve is sleeved on the double reduction axle and by dividing plate two and dividing plate three and uses bearings, then is fixed with chain hoist wheel on the axle sleeve between dividing plate two and the dividing plate three.The concrete characteristics of this programme also have, and also are supported with the pleasure boat axle between dividing plate one and dividing plate two, and the loop chain pleasure boat is arranged on the pleasure boat axle.Described three grades of deceleration ring gears fixedly are to adopt spline to be connected with shaft room.Described chain hoist wheel fixedly is to adopt spline to be connected with shaft room.Described deceleration box is to be made by the steel plate welding.
The beneficial effect of this programme can be learnt according to the narration to such scheme, owing in this scheme, adopt and in deceleration box, installed three dividing plates additional, the rotating shaft of deboost axles at different levels and chain hoist wheel and pleasure boat axle are supported by dividing plate, this has just increased the ability of load-bearing, in addition, increased a pleasure boat again, loop chain is increased, improved lifting strength, make it to be fit to the large-tonnage weight of lifting 10-50 ton, and used motor can be electronic or surge or the compressed-air controlled motor.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.
Description of drawings:
Fig. 1 is the structural representation of the utility model specific embodiment.
Fig. 2 is the structural representation of Fig. 1.
1 is deceleration box among the figure, and 2 is motor, and 3 is one-level deceleration ring gear, 4 for motor goes out shaft gear, and 5 is the pleasure boat axle, and 6 is dividing plate one, 7 is that dividing plate two, 8 is the loop chain pleasure boat, and 9 is axle sleeve, 10 is the double reduction axle, and 11 is chain hoist wheel, and 12 is three grades of deboost axles, 13 is that dividing plate three, 14 is the double reduction ring gear, and 15 is three grades of deceleration driving gears, 16 is three grades of deceleration ring gears, and 17 is the double reduction driving gear.
The specific embodiment:
For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by a specific embodiment.
