Abstract
The invention provides a lifting platform comprising a base, a bottom frame, an upper platform, a ladder and a shear and fork frame. The shear and fork frame comprises two pairs of shears and forks located on top beams on the two sides of the bottom frame correspondingly. Each pair of shear and fork comprises a first support and a second support, wherein the middle of each first support and the middle of the corresponding second support are connected in an intersected manner. Inner grooves are formed in the other ends of bottom beams of the upper platform and the other ends of the top beams of the bottom frame. Lead screws are fixed into the inner grooves of the top beams of the bottom frame and the inner grooves of the bottom beams of the upper platform correspondingly. The lead screws are sleeved with sliding sleeves. Threads matched with the lead screws are arranged on the inner surfaces of the sliding sleeves. The bottoms of the second supports are hinged to the sliding sleeves on the bottom frame. The tops of the first supports are hinged to the sliding sleeves on the upper platform. According to the lifting platform, a rotating wheel drives the lead screws to rotate, and therefore the shear and fork frame is driven to rise and fall in the manner that the sliding sleeves rotate on the lead screws. Compared with a traditional elevator, stability is greatly improved, electric power mechanisms do not need to be used, and the device cost is reduced.

Side, the ladder is installed on the outside of the underframe, and the bottom of the ladder is located at ground, the top of the ladder with described
Upper mounting plate is hinged, and the fork-shearing frame includes two pairs of scissors, and two pairs of scissors are located on the back timber of both sides of the underframe respectively,
Scissor described in each pair includes that two intersect the support one and support two being connected at middle part, and the top of the support one is articulated with institute
One end of the bottom girder of upper mounting plate is stated, the bottom of the support two is articulated with one end of the back timber of the underframe, the upper mounting plate
The other end of the back timber of the other end of bottom girder and the underframe has inside groove, the back timber inside groove of the underframe and the upper mounting plate bottom
Screw mandrel is respectively fixed with the inside groove of beam, on the screw mandrel, is cased with slip cap, the inner surface of the slip cap be provided with described
The screw thread that screw mandrel matches, the bottom of the support two is hinged with slip cap on the underframe, the top of the support one
It is hinged with slip cap on the upper mounting plate.
Particularly, two screw mandrels on the back timber of the underframe both sides are stretched out outside the underframe, and the screw mandrel
End be separately installed with runner, be connected with gear by driving-chain between two runners, that is, rotate any one runner, separately
Outer runner synchronous axial system therewith.
Particularly, below the base, wheel is additionally provided with.
The invention has the beneficial effects as follows：The present invention is a kind of hoistable platform of scissor-type, makes to be cased with fork-shearing frame and screw mandrel
Slip cap be connected, using driven by rotating wheel screw mandrel rotate so that slip cap mode of turn on screw mandrel drives fork-shearing frame
Lifting, compared to fork-shearing frame in conventional elevator movable end be embedded in guide rail slide method, substantially increase stability,
By gear and transmission Chain conveyer between the screw mandrel of both sides, it is ensured that the synchronicity of both sides fork-shearing frame activity, and electricity is not required the use of
Aerodynamic force mechanism, reduces equipment cost.
