Description
Technical field
The utility model is related to the upper component of container crane more particularly to a kind of decelerating motor driving roller chain are new
The electronic restocking of type arrangement.
Background technology
At present, in general quayside container crane and container gantry restocking, suspension centre driven in translation generally uses herein below：
1：Electric pushrod driving pan carriage is mobile or " K " series " three-in-one " decelerating motor driving roller chain, drive are flat
Move frame movement；Or the horizontal decelerating motor driving roller chain of " R " series " three-in-one ", drive pan carriage movement.
2：At most only 480 millimeters of left or right translational movement stroke
3：Although two hinge shafts have been provided below in translation track, but be in addition specially provided with deck again, prevent translation track
Lateral rotation.
4：Each idler wheel under suspension centre pan carriage is provided with two rolling bearings.Idler wheel can only be rotated around roller shaft, be hung
Point pan carriage rolls under the effect of restocking side-sway power, and idler wheel also can be rolled accordingly；Contact of the idler wheel with orbital plane can also be connect by line
Thixotroping is point contact.
These settings have the following problems：
1. using electric pushrod, shift motion is limited.Due to being in a limited space（Restocking essence is generally no more than collection
Vanning width, generally should be smaller than 2438）, electric pushrod is larger in moving direction size, so, the stroke of electric pushrod is limited
System.Only 480mm.If electric pushrod increases stroke again, restocking width will be more than container width.In this way, crane exists
When drawing case, the container of surrounding may be encountered.
The three-in-one decelerating motor cost of " 2. K " series is higher
3. current technology is driven using " K " series " three-in-one " decelerating motor and " R " series " three-in-one " decelerating motor
When, drive sprocket and driven sprocket central axis are arranged in parallel in horizontal plane, see Fig. 1.Due in container operation,
The startup and braking of monkey and cart can all cause the back and forth or left and right of restocking to swing, and connection suspension centre can be caused by swinging
The steel wire rope of pan carriage and veritcal linearity are into 4 ~ 8 ° of angle（Small vehicle speed is fast, and deflection angle hinge is big）, the water of this angle generation
Divide power equally, can be acted on by suspension centre pan carriage on roller chain.
Since drive sprocket and driven sprocket axis are arranged in parallel in the horizontal plane, the roller centre line of roller chain
Can be arranged in parallel in the horizontal plane, in Fig. 1, above-mentioned horizontal force action is in the side of roller chain；That is, horizontal masterpiece
Used in the axial direction of roller chain roller, roller chain cannot rotate in this direction, can only undertake the moment of flexure of this horizontal force generation：
1. roller chain generates additional bending moment, for roller chain not only by pulling force, but also bending moment, the bearing capacity of roller chain will be significantly
It reduces.
2. if roller chain is subjected only to pulling force, roller chain can be fine with the situation that engages of sprocket faces.And roller chain is both held
When being born moment of flexure again by pulling force, roller chain will drastically deteriorate with the situation that engages of sprocket faces.See Fig. 2, gently a then side load
Drastically increase, and another side load strongly reduces.It is heavy then, the field of conjugate action is while only a small amount of contact, and the another side field of conjugate action and rolling
Subchain roller is not exposed to so that roller chain is contacted with sprocket engagement by face to be become line and contact, and causes roller chain and sprocket
Bearing capacity declines significantly.
4. since translation track is specially provided with deck, translation track lateral rotation is prevented.Restocking swings the level generated
It is lateral that component acts on suspension centre pan carriage, and when restocking swing angle is more than 2.5 °, suspension centre pan carriage will roll, and idler wheel also can phase
It should roll；Contact of the idler wheel with orbital plane can also be contacted from line becomes point contact；The contact strength of idler wheel and orbital plane can be drastically
Increase.
In view of the above, it is necessary to a kind of change roller chain be provided and not only undertaken pulling force but also undertaken the situation of additional bending moment
Electronic restocking.
The content of the invention
In place of the utility model is avoids above-mentioned the shortcomings of the prior art, a kind of new type of drive and rolling are provided
