The inner side of the movable guide frame 1 is provided with a lifting oil cylinder guide frame 6 through a support rod, and the lifting oil cylinder guide frame 6 is provided with a pulley block 8 through a support shaft.
The specific structure and function of the utility model are as follows:
the device mainly comprises a movable guide frame 1, a fixed guide frame 2, an outer guide supporting wheel 3, an inner guide supporting wheel 4, a lifting oil cylinder 5, a lifting oil cylinder guide frame 6, a force sensor 7, a pulley block 8, a traction cable 9 and a connecting beam 10.
The movable guide frame 1 is sleeved in the fixed guide frame 2, and the outer guide supporting wheel 3 and the inner guide supporting wheel 4 are respectively arranged at the upper part of the fixed guide frame 2 and the lower part of the movable guide frame 1;
the fixed end of a rodless cavity of the lifting oil cylinder 5 is arranged on the chain bucket system 11 stepping trolley through a hinge shaft, the pulley block 8 is arranged at the head of a piston rod of the lifting oil cylinder 5, the traction cable 9 is wound through the pulley block 8, one end of the traction cable 9 is fixed on the movable guide frame 1, the other end of the traction cable is fixed on the chain bucket system stepping trolley through a connecting seat, and the force sensor 7 is arranged.

The connecting beam 10 is connected and installed in the upper supporting structure of the chain bucket system through a hinge shaft in a connecting mode to form a cross connecting mode and is connected and fixed with the movable guide frame 1.
In the actual use process:
when the lifting oil cylinder 5 does telescopic action, the free end of the traction cable 9 is driven to lift through the pulley block 8, and then the movable guide frame 1 and the chain bucket system are driven to integrally lift,
elevating speed V of chain bucket system is VOil cylinder×m
Wherein: m is the multiplying power of the pulley block 8, and the multiplying power of the pulley block 8 can be comprehensively considered according to factors such as surge corresponding speed of an operation area, chain bucket lifting height and the like.
The increase of the lifting speed of the chain bucket lifting system is realized through the pulley block 8, the contact pressure between the feedback chain bucket material taking system and the material pile is detected in real time through the force sensor 7, the material eating depth and the excavating force of the chain bucket system to materials with different characteristics are adjusted, and the chain bucket and the material pile are in a constant-pressure contact state.
When the cabin is cleaned, the working pressure of the lifting oil cylinder 5 is adjusted according to the feedback value of the force sensor 7, so that the chain bucket system and the residual material layer are in a small-pressure suspension contact state to realize the cabin cleaning operation of the chain bucket, and meanwhile, the small contact force can avoid the damage to the cabin bottom plate when the chain bucket is in contact with the bottom plate.
The chain bucket material taking system is a rigid system, when the chain bucket system works in a cabin, the ship body fluctuates up and down due to surging, so that horizontal and vertical acting forces are generated between a material pile in the cabin and the chain bucket system, and the acting forces have adverse effects on the safety of a chain bucket ship unloader and the ship body. In order to ensure the safe operation of the chain bucket ship unloader, a relatively stable force difference value is formed between a chain bucket system and a material pile according to surge data of an operation area and the characteristics of operation materials, and the force difference value is ensured by the working pressure of a lifting oil cylinder 5 and the feedback data of a force sensor 7 through PLC system operation:
ΔF1 operating condition＝GChain bucket system-FLifting oil cylinder。
When the surge is acted on, the material pile in the cabin can generate upward jacking force to the chain bucket system, and the force difference value is as follows:
ΔF2 operating condition＝GChain bucket system-FLifting oil cylinder-FTop lift force of material pile，
The chain bucket material taking system 11 can move upwards under the action of the material pile jacking force, at the moment, the flexible traction cable 9 can actively release the jacking force, the chain bucket system automatically moves upwards along with the material pile, the movable guide frame 1 also moves upwards along with the chain bucket system, meanwhile, the force sensor 7 transmits a force difference change signal to the PLC, the PLC can guide the lifting oil cylinder 5 to rapidly extend out and enable the flexible traction cable 9 to be in a tensioning state to achieve new balance, and the acceleration pulley block 8 on the upper portion of the rod cavity is accelerated through the lifting oil cylinder 5, so that the chain bucket system can be rapidly separated from the material pile, further, the anti-surge protection is realized, and the chain bucket system is prevented from being damaged under the surge effect. When the surge disappears, the force sensor 7 sends a signal again, the lifting oil cylinder 5 retracts rapidly, the chain bucket and the material pile contact again, the material taking operation is continued, the whole process is rapid in response, safe and reliable, and the operation efficiency of the chain bucket material taking system 11 is not affected.
The above description is intended to illustrate the present invention and not to limit the present invention, which is defined by the scope of the claims, and may be modified in any manner within the scope of the present invention.
