Abstract
The invention discloses a double-column lifting machine. A first lifting column and a second lifting column are respectively provided with a lifting arm, a lifting nut, a lead screw and a motor. The lifting arms and the lead screws are screwed through the lifting nuts, the upper ends of the lead screws are sleeved with lead screw belt pulleys, motor shafts of the motors are sleeved with motor shaft belt pulleys, and the lead screw belt pulleys are connected with the motor shaft belt pulleys through belts. According to the double-column lifting machine, a lead screw and nut lifting mode is adopted and belongs to the traditional technology, and the double-column lifting machine is reliable and safe; the small belt pulleys of the motor shafts are connected with the large belt pulleys of the lead screws, and the speed reducing effect and the slipping preventing effect are played in the synchronous pulley and synchronous belt transmission mode; the first lifting column and the second lifting column are fixed to the ground through expansion bolts, no bottom plate exists between the two columns for connection, vehicles can enter or exit from the double-column lifting machine without bumping, assembling is simple, and the width between the two columns can be adjusted; due to the adoption of the non-metal nylon nuts, the lead screws and the nuts are lubricated only by filling grease, no oil filling pump is needed for filling lubricating oil, and cost is reduced; the double-column lifting machine is simple in structure and quite practical.
Description
Technical field
The present invention relates to lifting machine technical field, particularly relate to a kind of double-column lifter.
Background technology
Double-column lifter is the lifting equipment that automobile maintenance industry generally uses, and vehicle sails between two posts, at the bottom of lift arm placing car, minibus can be lifted.
The form that current lifting machine uses is double-column hydraulic formula mostly, between symmetrically arranged first lifting post and the second lifting post, arrange connecting bottom board, be twin columns is keep the steel rope balanced to pass through base plate below.Or keeping balance without base plate connection but by the cruciform bracing on top by the steel rope of both sides, the topmost problem of this machine is that Installation and Debugging are complicated, and high for installation specification, technology is more extensive, simple.
Double-column lifter is also had to be screw mandrel/lift nut form.Two intercolumniations have base plate to connect, and by a direct motor drive, the lifting of another post is realized by base plate lower driving chain or right-angle gear box.The processing of this lifting machine, Installation and Debugging require higher, and cost is also than the height of hydraulic pressure.
Therefore, a kind of double-column lifter of special needs, to solve problems of the prior art.
Summary of the invention
The object of the invention is to solve in prior art, double-column lifter cost be higher, Installation and Debugging are complicated, defect that technical requirements is higher, provide a kind of double-column lifter to solve the problems referred to above.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of double-column lifter, comprise symmetrically arranged first lifting post, the second lifting post, it is characterized in that: described first lifting post and the second lifting post arrange lift arm, lifting nut, screw mandrel, motor respectively, described lift arm screws screw mandrel by lifting nut, the sheathed screw mandrel belt pulley in upper end of described screw mandrel, sheathed motor shaft belt pulley on the motor shaft of described motor, described screw mandrel belt pulley is connected by belt with motor shaft belt pulley.
In the present invention, the diameter of described screw mandrel belt pulley is greater than the diameter of motor shaft belt pulley.
In the present invention, described first lifting post and the second lifting post fix on the ground respectively by expansion bolt.
In the present invention, described lifting nut is made up of nylon material.
In the present invention, described first lifting post arranges electric cabinet.
In the present invention, the electric cabinet on described first lifting post is built with PLC.
In the present invention, described first lifting post is connected by hollow iron pipe with the second lifting post, arranges power lead and signal control line in described hollow iron pipe.
In the present invention, in the side of described first lifting post and the second lifting post upper screw rod belt pulley, opto-electronic pickup is set respectively.
The present invention compared with the existing technology, has the following advantages and beneficial effect:
1, feed screw nut is adopted to be elevated pattern, conventional art, reliable and secure.
2, connect the little timing belt pulley of motor shaft and the large timing belt pulley of screw mandrel with Timing Belt, play the object slowing down and avoid to skid.
3, the first lifting post and the second lifting post fix on the ground respectively by expansion bolt, connecting, vehicles while passing can being made without jolting between two posts without base plate.
4, adopt expansion bolt, make simply assembled, the width-adjustable of center-to-center.
5, owing to using nonmetallic nylon nut, the lubrication of screw mandrel and nut only need add greasing, without the need to separately establishing fuel charger charging-up lubricant oil, simplifying the structure, also reducing cost.
6, the up and down balance system of double-motor is ensured by synchronizing wheel and Timing Belt, and error is controlled by PLC, cheap, reduces costs.
