Description
Technical Field
The application relates to the field of automatic operation devices of a port and dock yard, in particular to a self-help pusher for safe operation of a high-speed rail crane of an automatic yard.
Background
The yard of the automated dock adopts full-automatic or semi-automatic (manual remote operation) yard loading and unloading machinery and adopts full-automatic container high-speed rail crane (ARMG). In order to maximally realize man-machine separation and improve the operation efficiency of the wharf and the operation safety of a yard, an automatic wharf yard is isolated from other operation areas through fences, and a closed management mode is adopted.
However, in the existing design, two high-speed rail cranes are arranged in each storage yard, and the loading and unloading operation is completed through the movement of the two high-speed rail cranes in the sea-side operation and the land-side operation, so that the high-efficiency operation is realized.
If any one of the high-speed rail cranes in the yard is failed, the operation efficiency of the whole wharf loading and unloading ship can be affected, the container region of the traditional container yard can be repaired by means of other equipment, such as a front crane and a large forklift, and the container region can be directly opened for temporary auxiliary emergency operation, but when other machines in the automatic yard cannot enter the yard due to the limitation of layout, and the failure maintenance is carried out, the high-speed rail crane is difficult to hoist to the maintenance region for maintenance in a conventional mode. It is now necessary to push the failed one to the terminal (sea or land side) service area for service using a non-failed one of the rail cranes.
If the high-speed rail crane is in windy weather, the locking of the high-speed rail crane braking device is not firm or the braking device is damaged, and the high-speed rail crane is easily blown away by windy in the moving process, so that the high-speed rail crane moves irregularly on the ground guide rail, and accidents are caused.
The application patent of China with the application number of CN201611218220.7 discloses a self-service pusher for the safety operation of an automatic yard high-speed rail crane, which adopts a locking device and a locking seat to connect a sea side rail crane and a land side rail crane so as to solve the problems in the prior art. But during use it was found that: although the first buffer and the second buffer are arranged, when the first buffer and the second buffer are impacted, the impact force is large, the inertia is also large, after the connecting hook is buckled with the lock catch, if the control is bad, the second buffer can move to one side of the first buffer under the action of the inertia, when one side of the lock catch is contacted with the fixed seat of the second buffer, the buffer seat of the second buffer can not shrink inwards to the fixed seat to play a role of buffering, the impact force caused by the inertia can only be applied to the buffer seat on the first buffer and the connecting rack, but the lock catch is limited to the connecting hook, the connecting hook can not rotate any more, therefore, the connecting gear can not rotate any more, the force on the connecting rack is applied to the meshing position of the gear teeth of the connecting rack and the connecting gear, the meshing bears a huge impact force, and the service life of the connecting gear and the connecting rack is greatly reduced. Therefore, the above-described technique has the technical disadvantage as described above. Moreover, the technology can realize electric automatic control, the technical difficulty of the whole operation process is high, and the problems can occur if the control is not good, so that the service lives of the connecting gear and the connecting rack are greatly reduced.
