Steel wire rope is wound between one pulley and second pulley, one end of the steel wire rope is fastened with reel to be connected, the steel wire
The fixed pull ring connection of the other end of rope side corresponding with being arranged on ramp.
In above-mentioned technical proposal, decelerator is additionally provided between the reel and motor, the output shaft of the motor is with subtracting
The input shaft drive connection of fast device.
In above-mentioned technical proposal, connected between the output shaft of the motor and the input shaft of decelerator by shaft coupling transmission
Connect.
In above-mentioned technical proposal, brake, the output shaft of the decelerator are additionally provided between the decelerator and reel
It is connected with one end of brake, the other end of the brake and the transmission of rotary axis of reel connect.
In above-mentioned technical proposal, the pulley base for installing first pulley and second pulley is provided with the steel drawn bridge.
Compared with prior art, the invention has the advantages that：
The automatic drive device of the present invention is drawn by the simultaneously wound steel wire rope of spool turns using the pulling force traction steel of steel wire rope
Bridge moves up and down along ramp, efficiently reduces load of the steel drawn bridge to landing stage, and eliminates the peace that steel drawn bridge moving belt comes
Full hidden danger, solving traditional inclined wharf large steel approach bridge, to move up in mode the safety such as landing stage hoist engine overload, anchor chain fracture hidden
Suffer from, to the pusher on landing stage when steel drawn bridge is to its caused large drag forces and static steel drawn bridge when also effectively reducing landing stage displacement
Power.In addition, the steel wire rope of steel drawn bridge both sides is by the way of synchronous, effectively prevent steel drawn bridge roller from gnawing rail.

Embodiment
Describe the performance of the present invention in detail with reference to case study on implementation, but they do not form the limit to the present invention
It is fixed, it is only for example.Simultaneously by illustrating that advantages of the present invention will become clearer and be readily appreciated that.
The automatic drive device of a kind of sloping quay steel drawn bridge of the invention as shown in the figure, for driving steel drawn bridge 9 along oblique
Ramp 10 moves up and down, and it includes being arranged on the mounting seat 1 of the top of steel drawn bridge 9, and reel 2 is provided with and for driving in mounting seat 1
The motor 3 of the rotary work of movable reel 2；A first pulley 4.1, steel drawn bridge 9 are each provided with the upper main chord of the both sides of steel drawn bridge 9
A second pulley 4.2 is each provided with the lower main chord of both sides, is provided with steel drawn bridge 9 for installing the He of first pulley 4.1
The pulley base 12 of second pulley 4.2.Steel is wound between the first pulley 4.1 and second pulley 4.2 of the same side of steel drawn bridge 9
Cord 5, one end of steel wire rope 5 is fastened with reel 2 to be connected, and the other end of steel wire rope 5 is corresponding with being arranged on ramp 10
The fixed pull ring 11 of side connects.
Decelerator 6 is additionally provided between reel 2 and motor 3, the output shaft of motor 3 connects with the input shaft transmission of decelerator 6
Connect, be connected between the output shaft of motor 3 and the input shaft of decelerator 6 by shaft coupling 7.Between decelerator 6 and reel 2 also
Brake 8 is provided with, the output shaft of decelerator 6 is connected with one end of brake 8, the other end and the reel 2 of brake 8
Transmission of rotary axis connects.
The course of work of the present invention：When fluctuation of water table, the present apparatus twists anchor action with landing stage and cooperated, to realize that steel draws
Bridge and the adjustment of landing stage position.According to the safe distance on the bracket of landing stage, steel drawn bridge 9 is first moved to the distalmost end of safe distance,
The hoist engine on landing stage 13 twists safe distance to minimum, the subsequent motor 3 that anchor movement landing stage 13 is reduced on bracket and drives reel 2 to revolve
Turn, two steel wire ropes are drawn by the first pulley 4.1 and second pulley of steel drawn bridge both sides, the fixed of 4.2 ramp both sides respectively
