Description

The rotating mechanism of electric lifting device
Technical field
The utility model relates to the electric lifting device field, specifically be a kind of rotating mechanism of electric lifting device.
Background technology
At present, electric lifting device is mainly used in miniature or light-duty truck handling goods or operation field handling goods, its structure mainly comprises principal arm, transverse arm, pedestal, lifting appliance, pedestal mainly is installed on the charge and discharge operations platform of bench board or lorry, be provided with rotating mechanism between principal arm and the pedestal and be located at the interior live spindle of rotating mechanism, lifting appliance is located on the transverse arm.The rotation of above-described its rotating mechanism of electric lifting device is controlled by manpower.Its rotating mechanism be between the bottom of live spindle and the pedestal by the combination of ball-bearing casing and surface bearing or the combination of axle sleeve and surface bearing, finish rotation by the promotion of manpower again.But under the heavier situation of lifting cargo, promote to rotate to carry out handling goods with artificial again, so not only effort and very difficult real-time control position have reduced the accuracy that loads and unloads.
Moreover, not only to bear goods to its downward pressure owing to live spindle in the process of lifting, and to bear the torsion in when rotation, the rotational structure of the combination of the combination by ball-bearing casing and surface bearing or axle sleeve and surface bearing between the bottom of live spindle and the pedestal in rotating mechanism like this, in carrying out long loading and unloading operation, because the combination of ball-bearing casing and surface bearing or its torsional strength of combination of axle sleeve and surface bearing are little, fragile, so that service life of bont short.
The utility model content
The technical problems to be solved in the utility model is, overcomes above existing technological deficiency, and a kind of rotating mechanism of the electric lifting device of control position in real time can rotate automatically and rotate the time is provided.
Technical solution of the present utility model is, a kind of rotating mechanism with electric lifting device of following structure is provided: it comprises pedestal, principal arm, live spindle, the centre hole I normal-running fit of the bottom of described live spindle and pedestal, be provided with electric rotating mechanism between described pedestal and the principal arm, described electric rotating mechanism comprises drive motor, retarder, driven wheel, rotating disc and the gear ring of captiveing joint with the centre hole I outer wall of pedestal, the output axle head of described drive motor is connected with retarder, described retarder is captiveed joint with rotating disc, captive joint with driven wheel in the output shaft lower end of retarder, described driven wheel and gear ring engagement; Described live spindle is captiveed joint with the center hole II of rotating disc, captives joint with the upper surface of rotating disc in the lower end of described principal arm.
After adopting above structure, the rotating mechanism of the utility model electric lifting device compared with prior art, have the following advantages: drive motor drives driven wheel around the gear ring rotation that is fixed on pedestal centre hole outer wall by retarder, thereby the loading and unloading of goods are carried out in the rotation that makes the rotation of rotating disc drive principal arm.The people only need come the rotating of controlling and driving motor just can control the rotation of principal arm by control handle, under the heavier situation of lifting cargo, and control position in real time during rotation, and saved manpower, improved loading and unloading accuracy and work efficiency.
As a kind of improvement, the bottom of described live spindle and pedestal centre hole normal-running fit are meant between described live spindle and the pedestal center bore inner wall tapered roller bearing is installed.Described tapered roller bearing not only can be resisted the downward pressure of live spindle to pedestal, and can resist the torsion of live spindle, has increased the service life of rotating mechanism greatly.
Description of drawings
It shown in the accompanying drawing structural representation of the rotating mechanism of the utility model electric lifting device.
As shown in the figure:
1, pedestal, 2, principal arm, 3, drive motor, 4, retarder, 5, output shaft, 6, driven wheel, 7, gear ring, 8, rotating disc, 9, center hole II, 10, live spindle, 11, tapered roller bearing, 12, bearing, 13, centre hole I.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in the figure.
The rotating mechanism of the utility model electric lifting device, it comprises pedestal 1, principal arm 2, live spindle 10, the centre hole I13 normal-running fit of the bottom of described live spindle 10 and pedestal 1, be provided with electric rotating mechanism between described pedestal 1 and the principal arm 2, described electric rotating mechanism comprises drive motor 3, retarder 4, driven wheel 6, rotating disc 8 and the gear ring 7 of captiveing joint with the centre hole I13 outer wall of pedestal 1, the output axle head of described drive motor 3 is connected with retarder 4, described retarder 4 is captiveed joint with rotating disc 8, captive joint with driven wheel 6 in output shaft 5 lower ends of retarder 4, described driven wheel 6 and gear ring 7 engagements; Described live spindle 10 is captiveed joint with the center hole II 9 of rotating disc 8, captives joint with the upper surface of rotating disc 8 in the lower end of described principal arm 2.
Captiveing joint with the upper surface of rotating disc 8 in the lower end of described principal arm 2, is meant that the lower end of described principal arm 2 captives joint with center hole II 9 upper surfaces of rotating disc 8, and the dead in line of the axis of principal arm 2 and center hole II 9.
Also be provided with bearing 12 between the output shaft 5 of described retarder 4 and the rotating disc.
The bottom of described live spindle 10 and pedestal centre hole 13 normal-running fiies are meant between described live spindle 10 and pedestal centre hole 13 inwalls tapered roller bearing 11 is installed.Adopt the combination of ball-bearing casing and surface bearing or the combination of axle sleeve and surface bearing that live spindle 10 is rotated,, and will bear goods lifting, the torsion when principal arm 2 rotates because live spindle 10 not only will bear goods to its downward pressure.Long-time use can make the combination of ball-bearing casing and surface bearing or the combination wearing and tearing of axle sleeve and surface bearing, and rotating mechanism is damaged.The lower end of described principal arm 2 is fixedly connected on centre hole 9 upper surfaces of rotating disc 8, captives joint with S. A. 10 tops by bolt again.
The principle of work of the rotating mechanism of the utility model electric lifting device: during work, drive motor 3 drives driven wheel 6 rotations by the output shaft 5 of retarder 4, gear ring 7 engagements that driven wheel 6 is captiveed joint with the centre hole I13 outer wall of pedestal 1, driven wheel 6 is in the time of gear ring 7 rotations, driven rotary dish 8 and live spindle 10 rotate, thereby drive principal arm 2 rotations of captiveing joint with rotating disc 8.The people only need come the rotating of controlling and driving motor 3 just can control the rotation of principal arm 2 by control handle.
