Description
Technical field:
The present invention relates to a kind of hoistable platform, especially a kind of hoistable platform of mechanical structure driving.
Background technique:
Mechanical elevating platform currently on the market is mainly to move before and after utilizing screw rod to drive the idler wheel being located among scissors fork
It moving, control scissors fork is opened and is folded, thus realize the up and down motion of hoistable platform, since the high precision of screw rod requires, this
Kind structure needs huge, complicated auxiliary support structure, and once goes wrong and be difficult to overhaul.
Summary of the invention:
In order to overcome in the prior art accessory structure it is complicated, the defects of maintenance cost is high, the present invention provides a kind of simple drive
The mechanical structure of dynamic scissors fork movement, driven gear are welded in interior scissor arms, and driving gear passes through drive shaft and outer scissor arms
The transmission shaft of connection, decelerating motor is connected by shaft coupling with drive shaft, and decelerating motor rotates forward, and driving gear drives driven gear
It is rotated up, opens scissors fork；Decelerating motor reversion, driving gear driving driven gear rotate down, and fold scissors fork
Get up.To realize the lifting of platform.
The technical solution adopted by the present invention to solve the technical problems is: a kind of scissors fork structure of gear driving, including
Interior scissor arms, outer scissor arms, driven gear, driving gear and decelerating motor, interior scissor arms and outer scissor arms are connected by mandrel,
Driven gear is welded in interior scissor arms, and driving gear is connected by spline with drive shaft, is provided with circular hole in outer scissor arms, in hole
Bearing is installed, drive shaft is passed through from circular hole, and drive shaft outer end is equipped with circlip and gasket, prevents drive shaft slid inward, is driven
Moving axis inner end passes through spring bearing, is connected by shaft coupling with transmission shaft, and transmission shaft is connected by spline with decelerating motor, subtracts
Speed motor is mounted on the base, and pedestal is then welded on the two outer scissors yokes in left and right.When decelerator rotates forward, driving gear
Driven gear is driven to be rotated up, driven gear drives interior scissor arms to be rotated up, and platform rises；When decelerator inverts,
Driving gear drives driven gear to rotate down, and driven gear drives interior scissor arms to rotate down, platform decline；
The invention has the advantages that gear hoistable platform of the invention is while realizing lifting, not complicated branch
Support mechanism, structure is simple, convenient to overhaul.
Detailed description of the invention:
The following further describes the present invention with reference to the drawings.
Fig. 1 is the structural diagram of the present invention；
Specific embodiment
As shown in Figure 1, a kind of scissors of gear driving pitches structure, including interior scissor arms 11, outer scissor arms 1, driven gear
2, driving gear 5 and decelerating motor 12, interior scissor arms 11 and outer scissor arms 1 are connected by mandrel 3, and driven gear 2 is welded on interior
In scissor arms 11, driving gear 5 is connected by spline with drive shaft 13, and circular hole is provided in outer scissor arms 1, is equipped with bearing in hole
6, drive shaft 13 is passed through from the circular hole of outer scissor arms 1, and 13 outer end of drive shaft is equipped with circlip 8 and gasket 7, prevent drive shaft 13 to
Interior sliding, 13 inner end of drive shaft pass through spring bearing 9, are connected by shaft coupling 4 with transmission shaft 14, transmission shaft 14 passes through spline
It is connected with decelerating motor 12, decelerating motor 12 is mounted on pedestal 10, and pedestal 10 is then welded on the two outer scissors yokes 1 in left and right
On.When decelerator 12 rotates forward, driving gear 5 drives driven gear 2 to be rotated up, and driven gear 2 drives interior scissor arms 11
It is rotated up, platform rises；When decelerator 12 inverts, driving gear 5 drives driven gear 2 to rotate down, driven gear 2
Scissor arms 11 rotate down in driving, platform decline；
When the invention patent course of work is such that decelerator 12 rotates forward, driving gear 5 drives driven gear 2
It is rotated up, driven gear 2 drives interior scissor arms 11 to be rotated up, and platform rises；When decelerator 12 inverts, driving gear
5 drive driven gears 2 rotate down, and driven gear 2 drives interior scissor arms 11 to rotate down, platform decline.
