Description

Technical Field

[0001] The present invention relates to the technical field of the boom of a bucket wheel stacker-reclaimer, and specifically, to an adjustable anti-collision structure for the boom of a bucket wheel stacker-reclaimer. Background Art

[0002] Currently, the anti-collision structure of the boom of a bucket wheel stacker-reclaimer is a safety device installed on the boom of the bucket wheel stacker-reclaimer to prevent the boom from colliding with surrounding obstacles during operation.

[0003] There are many deficiencies in the existing anti-collision structures of the booms of bucket wheel stacker-reclaimers, and it is difficult to meet the safety requirements in complex operating environments. Traditional structures are often simply designed, lacking a multi-level protection and a mechanism to flexibly respond to collisions. Specifically, the existing technologies mainly have the following disadvantages: First, the protection of the traditional anti-collision structure of the boom of a bucket wheel stacker-reclaimer is single, lacking effective multi-level protection. When a collision occurs, it often relies only on a single protective component to resist, and cannot provide step-by-step protection according to the collision force, easily resulting in serious damage to the boom structure. Second, the response speed and sensitivity of the existing structures are relatively low. When a collision occurs, it cannot react quickly and adjust the protection state in a timely manner, thus increasing the risk and degree of damage caused by the collision. In addition, the repair and replacement of the traditional anti-collision structure are relatively difficult. Once a protective component is damaged, it often needs to be replaced as a whole, which not only increases the repair cost but also affects the normal operation and working efficiency of the equipment. Finally, the adaptability and flexibility of the existing structures are relatively poor. When facing different working conditions and collision situations, it cannot flexibly adjust the protection strategy and force, and it is difficult to meet the actual operating requirements. Summary of the Invention

[0004] The present invention provides an adjustable anti-collision structure for the boom of a bucket wheel stacker-reclaimer, which solves the problems of insufficient collision protection and high repair difficulty in the related technologies.

[0018] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of the present invention.

[0019] As Figures 1 to 7 shown, in this embodiment, an adjustable anti-collision structure for the cantilever of a bucket wheel machine includes a cantilever main body 1, a collision main body 3, and a plurality of collision protectors 2. The collision protectors 2 are arranged symmetrically in pairs on both sides of the cantilever main body 1, and the collision main body 3 is connected to one side of a plurality of collision protectors 2 at the same time; The collision protector 2 is composed of a limit frame 21, a gear 221, an auxiliary top plate 23 and a main top plate 24. The limit frame 21 is arranged on one side of the cantilever main body 1. The gear 221 rotates inside the limit frame 21. Both the auxiliary top plate 23 and the main top plate 24 are slidably assembled inside the main limit frame 21; The collision main body 3 is composed of a first fixing plate 31, a second fixing plate 32 and a connecting main board 33. The first fixing plate 31 and the second fixing plate 32 are connected to each other. The connecting main board 33 is connected to one side of the first fixing plate 31 and the second fixing plate 32.

[0020] Specifically, before the equipment is used, the collision protectors 2 are installed on both sides of the cantilever main body 1 in a pairwise symmetric and equidistant manner. After the collision protectors 2 are installed, the first fixing plate 31 and the second fixing plate 32 are installed at intervals on the top of the collision protectors 2. Subsequently, the connecting main board 33 is installed on both sides of the first fixing plate 31 and the second fixing plate 32. During the use of the cantilever, when a collision occurs on the side, through the collision of the collision object against the first fixing plate 31 and the second fixing plate 32, the main top plate 24 inside the collision protector 2 is retracted through the transmission of the gear 221 for protection. When the collision is relatively large, the auxiliary top plate 23 extends to the position of the main top plate 24 for collision abutment protection, realizing its multi-level protection. After the collision is completed, if there are impact injuries on the first fixing plate 31 or the second fixing plate 32 that are difficult to repair, they can be removed and replaced, realizing multi-module use and facilitating maintenance and replacement.

[0021] In this embodiment, rotating shafts 22 are arranged on both sides of the gear 221. The rotating shafts 22 are rotatably installed inside the limit frame 21. A first rack 232 is arranged on one side of the auxiliary top plate 23, and a second rack 241 is arranged on one side of the main top plate 24. Both the first rack 232 and the second rack 241 are engaged with the gear 221.

[0022] Specifically, the rotating shafts 22 arranged on both sides of the gear 221 are rotatably installed inside the limit frame 21. When the main top plate 24 generates collision protection and retracts, during the retraction process, the second rack 241 on the main top plate 24 drives the gear 221 to rotate. The rotation of the gear 221 drives the first rack 232 to slide through meshing with the first rack 232, so as to drive the auxiliary top plate 23 to extend while the main top plate 24 retracts. When the impact is relatively large, the auxiliary top plate 23 and the main top plate 24 are at the same height for simultaneous abutment protection, improving its protection performance.

[0023] In this embodiment, first limit grooves 231 are arranged on both sides of the auxiliary top plate 23, and second limit grooves 242 are arranged on both sides of the main top plate 24. The first limit grooves 231 and the second limit grooves 242 are used for limiting the auxiliary top plate 23 and the main top plate 24.

[0024] Specifically, when the auxiliary top plate 23 and the main top plate 24 slide, the first limit grooves 231 on both sides of the auxiliary top plate 23 and the second limit grooves on the main top plate 24 are limited in the limit frame 21 and can only slide up and down. When the main top plate 24 is retracted and the auxiliary top plate 23 is extended, effective limit sliding can be performed to ensure the stability of the limit.

[0025] In this embodiment, a first spring 234 is connected between the auxiliary top plate 23 and the limit frame 21. First dampers 233 are provided at both ends of the first spring 234. A second spring 244 and a third spring 246 are connected between the main top plate 24 and the limit frame 21. Second dampers 243 are provided at both ends of the second spring 244, and third dampers 245 are provided at both ends of the third spring 246.

[0026] Specifically, during the sliding of the main top plate 24, the third spring 246 provided at its bottom and the second spring 244 provided on one side thereof can assist its sliding. During a collision, effective shock absorption and buffering can be achieved through the springs. After the impact is completed, through the settings of the second damper 243 and the third damper 245, effective rebound recovery can be performed. The first spring 234 provided on one side of the auxiliary top plate 23 can assist in shock absorption and buffering during the buffering of the main top plate 24 by the second spring 244 and the third spring 246. The first damper 233 provided thereon can also provide rebound recovery, improving the buffering performance of the collision protector 2.

[0027] In this embodiment, a hinge rod 25 is movably hinged to the top of the main top plate 24. A connecting plate 251 is fixedly connected to the top of the hinge rod 25. An installation plate 26 is slidably assembled inside the connecting plate 251.

[0028] Specifically, a hinge rod 25 is movably hinged between the connecting plate 251 and the main top plate 24. The setting of the hinge rod 25 can effectively protect against angular displacement when the first fixing plate 31 and the second fixing plate 32 are displaced during the collision of the collision body 3, providing auxiliary protection for the first fixing plate 31 and the second fixing plate 32. An installation plate 26 is provided on the connecting plate 251, and the setting of the installation plate 26 can connect the first fixing plate 31 and the second fixing plate 32, improving their protection.

[0029] In this embodiment, shock-absorbing springs 252 are symmetrically arranged between the connecting plate 251 and the installation plate 26. Shock-absorbing dampers 253 are provided at both ends of the shock-absorbing springs 252.

[0030] Specifically, a shock-absorbing spring 252 is provided between the connecting plate 251 and the mounting plate 26. The shock-absorbing damper 253 provided on the shock-absorbing spring 252 can effectively protect the first fixing plate 31 and the second fixing plate 32 from shock during the daily use of the first fixing plate 31 and the second fixing plate 32 after the mounting plate 26 is connected to the first fixing plate 31 and the second fixing plate 32.

[0031] In this embodiment, first connecting blocks 311 are provided at both ends of the first fixing plate 31, second connecting blocks 321 are provided at both ends of the second fixing plate 32, and the first connecting blocks 311 are connected to the second connecting blocks 321.

[0032] Specifically, the first connecting block 311 provided at both ends of the first fixing plate 31 and the second connecting block 321 provided on the second fixing plate 32 are connected by bolts. One first fixing plate 31 and one second fixing plate 32 are connected at intervals, and then the first fixing plate 31 and the second fixing plate 32 are bolted to the mounting plate 26 to complete the installation of the first fixing plate 31 and the second fixing plate 32. When a certain first fixing plate 31 or second fixing plate 32 needs to be replaced, only the bolts thereon need to be removed, which is convenient for replacement.

[0033] In this embodiment, third connecting blocks 331 are provided at both ends of the connecting main board 33. The connecting main board 33 is connected to the first fixing plate 31 and the second fixing plate 32, and the third connecting blocks 331 are connected to the first connecting blocks 311 and the second connecting blocks 321.

[0034] Specifically, the connecting main board 33 is bolted to both sides of the first fixing plate 31 and the second fixing plate 32. Third connecting blocks 331 are further provided at both ends of the connecting main board 33, and the third connecting blocks 331 are connected to the first connecting blocks 311 on the leftmost first fixing plate 31 and the second connecting blocks 321 on the rightmost second fixing plate 32 by bolts.

[0035] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
