Abstract
The utility model discloses a step down gear mechanism of hand power truck crane, it sets up in the reducing gear box bottom plate including rotating, reduction case cover, the drive gear on the transmission shaft is located with dividing to transmission shaft on the connecting plate, driving travel drive sprocket, and the rotation sets up the driven shaft on reducing gear box bottom plate and reduction case cover, drive gear is located between reducing gear box bottom plate and the reduction case cover, driving travel drive sprocket is located between reduction case cover and the connecting plate, driven shaft and transmission shaft parallel arrangement of each other, the reducing gear and the drive gear meshing of installation on the driven shaft, the driven shaft is provided with driven gear in order to be used for driving meshing driving translation ground walking at its tip that stretches out the reducing gear box bottom plate. Adopt transmission shaft and driven shaft second grade transmission structure, take turns to the less power of exerting at driving travel drive chain and can make driven gear be used for the driving meshing driving lightly to walk, be equipped with the utility model discloses a hand power truck crane can be so that the translation operation be carried out in the driving of the bigger heavy burden of same operating personnel pulling.
Description
【Technical field】
This utility model is related to a kind of hand power truck crane, especially relates to a kind of reduction gearing mechanism of hand power truck crane, belongs to
Rane trolley technical field.
【Background technology】
Hand power truck crane is widely used in the occasions such as factory, warehouse, warehouse, harbour, power station and construction site, and weight is suspended on
Below hand power truck crane, the hand power truck crane of heavy burden can be walked along track girder, realizes hauling operation.
Hand power truck crane makes bangle wheel rotate by draging chain of starting, and the rotation of bangle wheel drives driving gearshaft to rotate, and passes
The end tooth engaged transmission of movable gear shaft is fixed on the tooth bar of track soffit so that the wheel of hand power truck crane is along track Liangping
Move, the deficiency that this known hand power truck crane exists wastes time and energy, work efficiency is low, have improvement necessary in fact.
【Utility model content】
The purpose of this utility model is to provide a kind of reduction gearing mechanism of labour-saving hand power truck crane, and it has the power of pulling
Gently, the high feature of work efficiency.
For this reason, this utility model provides following technical scheme as follows：
The reduction gearing mechanism of hand power truck crane, is arranged at reduction gearbox bottom board, gear box cover, the biography on connecting plate including rotating
Moving axis and the travelling gear being divided on power transmission shaft, driving hoofing part sprocket wheel, travelling gear is located at reduction gearbox bottom board and deceleration
Between case lid, driving hoofing part sprocket wheel is located between gear box cover and connecting plate, and its improvement is：Also include rotating setting
Driven shaft on reduction gearbox bottom board and gear box cover, driven shaft and power transmission shaft arrangement parallel to each other, what driven shaft was installed subtracts
Fast gear and travelling gear are connected by meshing transmission, driven shaft its stretch out the end of reduction gearbox bottom board be provided with driven gear with
Drive driving walking in engagement.
Preferably, above-mentioned travelling gear is 3: 1 with the speed reducing ratio of reduction gearing.
For improving the deceleration transmission accuracy of mesh, above-mentioned power transmission shaft and travelling gear are a single piece.
This utility model compared with prior art this have the advantage that：
Using power transmission shaft and driven shaft secondary transmission structure, garage of being expert at walks to apply less power on drive sprocket to make
Driven gear is used for engagement and drives driving easily to walk, equipped with hand power truck crane of the present utility model so that same behaviour
Making personnel pulls the driving of bigger heavy burden to carry out translating operation, thus embodies the feature that the power of pulling is light, work efficiency is high.
【Brief description】
Below in conjunction with the accompanying drawings this utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
In figure label declaration：
1- reduction gearbox bottom board, 2- gear box cover, 3- connecting plate；
4- power transmission shaft, 41- travelling gear；
5- driving hoofing part sprocket wheel；
6- driven shaft；
7- reduction gearing；

【Specific embodiment】
Refer to shown in Fig. 1, be preferred embodiment of the present utility model.
The reduction gearing mechanism of hand power truck crane, including rotation be arranged at reduction gearbox bottom board 1, gear box cover 2, on connecting plate 3
Power transmission shaft 4 and the travelling gear 41 being divided on power transmission shaft 4, driving hoofing part sprocket wheel 5, travelling gear 41 is located at reduction box
Between base plate 1 and gear box cover 2, driving hoofing part sprocket wheel 5 is located between gear box cover 2 and connecting plate 3.
Reduction gearbox bottom board 1 is fixed by bolt S using after alignment pin H positioning with gear box cover 2 again；Connecting plate 3 leads to
Cross strut 9 to be fixedly connected on outside gear box cover 2.
This utility model also includes rotating the driven shaft 6 being arranged on reduction gearbox bottom board 1 and gear box cover 2, driven shaft 6 with
Power transmission shaft 4 arrangement parallel to each other, the reduction gearing 7 that driven shaft 6 is installed is connected by meshing transmission with travelling gear 41, driven shaft 6
Its stretch out the end of reduction gearbox bottom board 1 be provided with driven gear 8 for engagement drive driving translationally walk.
Driven gear 8 is engaged with the tooth bar (not shown) being fixed on track girder (not shown) bottom surface, and driven gear 8 is along tooth bar
The process of engagement movement, that is, the wheel driving driving is along track girder translation gliding.
Reduction gearing 7 is located between reduction gearbox bottom board 1 and gear box cover 2.
Preferably, above-mentioned travelling gear 41 is 3: 1 with the speed reducing ratio of reduction gearing 7.
Its number of teeth of travelling gear 41 of the present utility model is 14 teeth, and the number of teeth of reduction gearing 7 is 42 teeth.
Equipped with bangle bar on known driving hoofing part sprocket wheel 5.
