Description

Technical Field

[0001] The invention relates to the technical field of bucket wheel machines, in particular to a bucket wheel machine boom and a bucket wheel machine. Background Art

[0002] Bucket wheel machine, also known as bucket wheel stacker and reclaimer, is a kind of high-efficiency loading and unloading machinery used in large dry bulk cargo yards for continuous transportation that can both stack and retrieve materials. It consists of a belt conveyor arm that can pitch and swing horizontally, a bucket wheel at the front end, a frame, and a running mechanism. The belt can run in both directions. When retrieving materials, the bucket wheel takes the materials and sends them out through the conveyor arm. When stacking materials, the goods transported by the main conveyor are thrown into the yard through the conveyor arm.

[0003] The existing bucket wheel crane front arm frame structure has too much deadweight, which will increase the load of the whole machine, reduce the stability of the machine, thereby reducing the operating efficiency, and increase the machine's requirements for the site's bearing capacity. Excessive deadweight may cause the machine to vibrate during operation, increase the wear and fatigue of mechanical parts, and thus increase the risk of failure. However, directly adjusting the counterweight frame inclination angle cannot effectively and evenly distribute the stress on the lever arm, which can easily lead to excessive local stress, causing structural fatigue and fracture risks. In addition, the counterweight frame inclination angle of the bucket wheel crane directly affects the balance and load-bearing capacity of the front boom support. However, the existing structure responds to the force changes of the front boom support by changing the counterweight frame inclination angle at the support body, which is difficult to take into account the stress concentration problem of each lever arm.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. By finely adjusting the inclination angles of the first rear arm beam and the second rear arm beam, the gravity distribution of the entire system can be effectively balanced, thereby reducing unnecessary stress accumulation and achieving delicate adjustment of the force. This measure can greatly reduce the risk of structural deformation caused by stress concentration. Through the intelligent control system inside the control box, the status of the first rear arm beam, the second rear arm beam and the pull rod can be monitored and automatically adjusted in real time to ensure that the system is always in the best working state, which not only ensures the stability of the structure but also improves work efficiency.

[0015] 2. The automatic adjustment system of the support frame and the connecting plate plays a vital role. The system can flexibly change the contact range of the connection between the support frame and the connecting plate according to actual needs, and optimize the force transmission path by expanding or reducing the contact area. In addition, the workbench is also equipped with an advanced adjustable mechanism. This design makes the longitudinal support force more evenly distributed, effectively avoiding the occurrence of local overload. The automatic adjustment not only improves the response speed of the system, but also significantly enhances the overall bearing capacity and stability of the structure. In order to further optimize the support frame, make full use of the arm changes generated when the bucket wheel machine moves on the first forearm beam and the second forearm beam;

[0016] 3. Through precise calculation and analysis, the support strength of the support frame and the connecting plate can be adjusted in time when the bucket wheel excavator performs rotation, walking and other actions. When the bucket wheel head performs rotational motion, the centrifugal force it generates can be cleverly used to reinforce the support area of ​​the second forearm beam and the first forearm beam. In order to ensure the safety and reliability of the support parts, an overload alarm device in the stress contact area is specially added. The device can monitor the stress conditions of the support position in real time. Once abnormal stress concentration or overload is detected, an alarm will be issued immediately to remind the operator to take timely intervention measures. This not only effectively prevents damage to the support position, but also eliminates the safety hazards of the bucket wheel excavator system, providing a strong guarantee for the long-term stable operation of the entire system.

[0026] The working principle of the above technical solution is:

[0027] In actual operation, by finely adjusting the inclination angles of the first rear arm beam 19 and the second rear arm beam 16, the gravity distribution of the entire system can be effectively balanced, thereby reducing unnecessary stress accumulation and achieving delicate adjustment of the force. This measure can greatly reduce the risk of structural deformation caused by stress concentration. Through the intelligent control system inside the control box 27, the states of the first rear arm beam 19, the second rear arm beam 16 and the pull rod 17 are monitored and automatically adjusted in real time to ensure that the system is always in the optimal working state, which not only ensures the stability of the structure but also improves the work efficiency. At the same time, the automatic adjustment system of the support frame 13 and the connecting plate 14 plays a vital role. The system can flexibly change the contact range of the connection between the support frame 13 and the connecting plate 14 according to actual needs, and optimize the force transmission path by expanding or reducing the contact area. In addition, the workbench 1 is also equipped with an advanced adjustable mechanism. This design enables the longitudinal support force to be more evenly distributed, effectively avoiding the occurrence of local overload. The automatic adjustment not only improves the response speed of the system, but also significantly enhances the overall bearing capacity and stability of the structure. In order to further optimize the support frame 13 and make full use of the arm changes generated when the bucket wheel machine moves on the first forearm beam 23 and the second forearm beam 15, through precise calculation and analysis, the support strength of the support frame 13 and the connecting plate 14 can be adjusted in time when the bucket wheel machine rotates, walks, etc. When the bucket wheel head 30 rotates, the centrifugal force it generates can be cleverly used to reinforce the support area of ​​the second forearm beam 15 and the first forearm beam 23. In order to ensure the safety and reliability of the supporting parts, an overload alarm device in the stress contact area is specially added. The device can monitor the stress conditions of the supporting position in real time. Once abnormal stress concentration or overload is detected, an alarm is immediately issued to remind the operator to take timely measures to intervene. This not only effectively prevents damage to the supporting position, but also eliminates the safety hazards of the bucket wheel machine system, providing a strong guarantee for the long-term stable operation of the entire system.

A rotating plate 9 is rotatably installed on the output end of the adjusting cylinder 35, and a rotating rod 32 is fixedly installed inside the connecting end of the first forearm beam 23 and the supporting connecting block 31, and the rotating plates 9 are fixedly installed on both sides of the rotating rod 32 respectively.

[0029] By starting the regulating cylinder 35 , the output end of the regulating cylinder 35 can drive the rotating plate 9 to move, thereby driving the rotating rod 32 to rotate, thereby rotating the first forearm beam 23 and adjusting the position of the bucket wheel head 30 .

[0032] Working principle: By finely adjusting the inclination angles of the first rear arm beam 19 and the second rear arm beam 16, the gravity distribution of the entire system can be effectively balanced, thereby reducing unnecessary stress accumulation and achieving delicate adjustment of the force. This measure can greatly reduce the risk of structural deformation caused by stress concentration. Through the intelligent control system inside the control box 27, the states of the first rear arm beam 19, the second rear arm beam 16 and the pull rod 17 are monitored and automatically adjusted in real time to ensure that the system is always in the optimal working state, which not only ensures the stability of the structure but also improves the work efficiency. At the same time, the automatic adjustment system of the support frame 13 and the connecting plate 14 plays a vital role. The system can flexibly change the contact range of the connection between the support frame 13 and the connecting plate 14 according to actual needs, and optimize the force transmission path by expanding or reducing the contact area. In addition, the workbench 1 is also equipped with an advanced adjustable mechanism. This design enables the longitudinal support force to be more evenly distributed, effectively avoiding the occurrence of local overload. The automatic adjustment not only improves the response speed of the system, but also significantly enhances the overall bearing capacity and stability of the structure. In order to further optimize the support frame 13, make full use of the arm changes generated when the bucket wheel moves on the first forearm beam 23 and the second forearm beam 15. Through precise calculation and analysis, the support strength of the support frame 13 and the connecting plate 14 can be adjusted in time when the bucket wheel performs rotation, walking and other actions. When the bucket wheel head 30 performs rotation, the centrifugal force generated can be cleverly used to strengthen the support area of ​​the second forearm beam 15 and the first forearm beam 23. In order to ensure the safety and reliability of the support part, an overload alarm device for the stress contact area is specially added. The device can monitor the stress condition of the support position in real time. Once abnormal stress concentration or overload is detected, an alarm is immediately issued to remind the operator to take timely measures to intervene, which not only effectively prevents damage to the support position, but also eliminates the safety hazards of the bucket wheel system, providing a strong guarantee for the long-term stable operation of the entire system. By starting the adjustment cylinder 35, the output end of the adjustment cylinder 35 can drive the rotating plate 9 to move, thereby driving the rotating rod 32 to rotate, so that the first forearm beam 23 rotates and the position of the bucket wheel head 30 is adjusted.
