[0055] The present invention also provides a winch load experiment method based on a rocker jib tower centralized control system, including the following steps:

[0056] Step 1: Embed the winch unit to be tested into the embedding groove, then the servo motor works to drive the turntable to rotate counterclockwise. Through the connection of the connecting rod, the counterclockwise rotation of the turntable drives the two moving blocks to move towards each other. The movement of the moving block causes the inclined plane to squeeze the roller, so that the insertion rod rises, and the insertion rod is inserted out of the movable hole and inserted into the installation hole at the bottom end of the rack. The moving block continues to move, causing the moving block to squeeze the insertion block, so that the insertion block can be moved out of the movable groove and inserted into the outer wall of the rack, thereby completing the horizontal and vertical positioning of the rack in the embedding groove;

[0058] Step 3: After the feed box is lifted by the work of the machine body, the top block moves upward under the elastic action of the third spring. The movement of the top block drives the movable plate to move until the movable plate abuts against the top end of the inner wall of the second movable cavity, causing the first buffer mechanism to start working. Then the air pump works to continuously inflate the air inlet pipe, and through the connection of the connecting pipe, the gas enters the inside of the inflation cavity to squeeze the top end of the piston plate, causing the piston plate to rise. The rising of the piston plate drives the fourth spring to rise and compress the fourth spring. The rising of the fourth spring drives the abutting plate to rise, the rising of the abutting plate drives the connecting rod to rise, and the rising of the connecting rod drives the top plate to rise, causing the second buffer mechanism to start working.

[0059] Technical effects and advantages of the present invention:

[0060] (1) With the setting of the first buffer mechanism in the present invention, when the load limit is exceeded and the load component falls, the first buffer mechanism can buffer the falling impact force, thus avoiding a large impact force between the second base and the load component. At the same time, through the cooperation of the second buffer mechanism and the pressurizing mechanism, triple buffer protection can be carried out when the feed box falls, improving the working stability of the experimental device and extending the service life of the experimental device;

[0061] (2) With the setting of the installation mechanism and the reinforcement mechanism in the present invention, by moving the moving block, the insertion block can be inserted into the groove on the outer wall of the frame to longitudinally position the frame in the insertion groove. At the same time, the moving block can also move to insert the insertion rod into the hole at the bottom end of the frame to horizontally position the frame in the insertion groove, thus avoiding the cumbersome bolt positioning method and improving the connection stability between the winch unit and the experimental device.

Detailed implementation manners

[0071] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0072] The present invention provides a Figures 1-8 winch load experiment device based on a rocker boom tower control system as shown. Embodiment

[0073] It includes a first base 101, a second base 102, a hoist unit, a mounting mechanism, a load assembly, and a first buffer mechanism. The hoist unit is arranged at the top of the first base 101, the mounting mechanism is arranged between the hoist unit and the first base 101, the load assembly is arranged at the top of the second base 102, and the first buffer mechanism is arranged inside the second base 102. The first buffer mechanism is used to mitigate the impact force when the load assembly falls. The hoist unit is fixed through the mounting mechanism, and then the hoist unit is connected to the load assembly, and the load experiment can be carried out. When the load limit is exceeded, when the load assembly falls, the first buffer mechanism can buffer the falling impact force, thereby avoiding a large impact force between the second base 102 and the load assembly, improving the working stability of the experimental device and extending the service life of the experimental device.

[0074] Among them, the first buffer mechanism includes a movable plate 402, a top block 403, and a third spring 407. A second movable cavity 401 is formed inside the second base 102. The outer wall of the movable plate 402 is slidably connected to the inner wall of the second movable cavity 401. The bottom end of the top block 403 is fixedly connected to the top end of the movable plate 402. A plurality of top blocks 403 are arranged at the top of the movable plate 402. A rubber pad is attached to the top end of the top block 403. A top groove 404 is formed at the top of the second base 102. The outer wall of the top block 403 is movably inserted into the inner wall of the top groove 404. A boss 405 is fixedly connected to the bottom end of the inner wall of the second movable cavity 401. Bottom holes 406 are formed at the bottom ends of the movable plate 402 and the top block 403. The boss 405 is inserted into the inner wall of the bottom hole 406. The third spring 407 is arranged between the top end of the boss 405 and the inner wall of the bottom hole 406. A second buffer mechanism is arranged below the movable plate 402. After the feed box 301 is lifted by the operation of the machine body 104, the top block 403 moves upward under the elastic action of the third spring 407. The movement of the top block 403 drives the movement of the movable plate 402 until the movable plate 402 abuts against the top end of the inner wall of the second movable cavity 401, so that when the feed box 301 falls, it will first contact a plurality of top blocks 403, thereby causing the top block 403 to move downward, and the falling impact force can be buffered through the third spring 407, avoiding a large hard collision between the feed box 301 and the second base 102.

[0075] Among them, the second buffer mechanism includes a top plate 502, a connecting rod 504, a fourth spring 509, a piston plate 508 and a pressurizing mechanism. A clamping hole 501 is formed at the bottom end of the inner wall of the second moving cavity 401. The top plate 502 is inserted into the inner wall of the clamping hole 501. The top end of the connecting rod 504 is fixedly connected to the bottom end of the top plate 502. Rubber pads are attached to the bottom end of the moving plate 402 and the top end of the top plate 502. A communication hole 503 is formed in the inner wall of the clamping hole 501. The outer wall of the connecting rod 504 is movably inserted into the inner wall of the communication hole 503. An inflation cavity 506 is formed in the inner wall of the communication hole 503. A pressing plate 507 is slidably connected to the inner wall of the inflation cavity 506. The top end of the pressing plate 507 is fixedly connected to the bottom end of the connecting rod 504. The fourth spring 509 is arranged below the pressing plate 507. The piston plate 508 is slidably connected to the inner wall of the inflation cavity 506. The piston plate 508 is arranged below the fourth spring 509. The pressurizing mechanism is arranged below the piston plate 508. The pressurizing mechanism includes an air pump 510 and a connecting pipe 512. An air inlet pipe 511 is arranged at the output end of the air pump 510. The air inlet pipe 511 is fixedly inserted into the interior of the second base 102. The connecting pipe 512 is fixedly inserted into the outer wall of the air inlet pipe 511. The interior of the connecting pipe 512 is communicated with the interior of the inflation cavity 506. When the air pump 510 works, it continuously inflates the air inlet pipe 511, and then through the connection of the connecting pipe 512, the gas enters the interior of the inflation cavity 506, squeezing the top end of the piston plate 508, causing the piston plate 508 to rise. The rising of the piston plate 508 drives the fourth spring 509 to rise and compresses the fourth spring 509. The rising of the fourth spring 509 drives the pressing plate 507 to rise. The rising of the pressing plate 507 drives the connecting rod 504 to rise. The rising of the connecting rod 504 drives the top plate 502 to rise. Thus, when the material box 301 falls and drives the top block 403 and the moving plate 402 to descend, during the descending process of the moving plate 402, it will contact the rising top plate 502, causing the top plate 502 to move downward, and then through the connection of the connecting rod 504, driving the pressing plate 507 to move downward. The downward movement of the pressing plate 507 can buffer the impact force through the fourth spring 509. At the same time, the fourth spring 509 will also generate an impact force on the piston plate 508, causing the piston plate 508 to move downward. At this time, the compressed air below the piston plate 508 will buffer the piston plate 508. Therefore, three buffer protections can be carried out during the falling process of the material box 301, further ensuring the stability of the operation of the experimental device. The air pump 510 is electrically connected to an external power supply through an external switch, which is convenient for the operator to control the air pump 510 and improves the safety and convenience of the operation of the air pump 510. Embodiment

[0076] Compared with the first embodiment, the hoisting unit includes a frame 103 and a body 104. The installation mechanism is arranged between the frame 103 and the first base 101. The body 104 is fixedly connected to the top of the frame 103. A groove is formed on the outer wall of the frame 103, and an installation hole is formed in the groove. Generally, the hoisting unit is installed and made to work by inserting bolts into the installation holes.

[0077] Among them, the installation mechanism includes an embedded groove 200, a plug 203, a moving block 204, a fixed rod 205, a fixed disk 208, a first spring 209 and a reinforcement mechanism. The embedded groove 200 is formed at the top of the first base 101. The outer wall of the frame 103 is movably inserted and connected with the inner wall of the embedded groove 200. A first moving cavity 201 is formed inside the first base 101. An activity groove 202 is formed between the first moving cavity 201 and the embedded groove 200. The outer wall of the plug 203 is slidably connected with the inner wall of the activity groove 202. The moving block 204 is slidably arranged on the inner wall of the first moving cavity 201. The fixed rod 205 is fixedly connected to the inner wall of the first moving cavity 201. A connection hole 206 is formed on one side of the plug 203. The outer wall of the fixed rod 205 is movably inserted and connected with the inner wall of the connection hole 206. A connection cavity 207 is formed on the inner wall of the connection hole 206. The outer wall of the fixed disk 208 is slidably connected with the inner wall of the connection cavity 207. One end of the fixed rod 205 is fixedly connected to one side of the fixed disk 208. The first spring 209 is arranged on one side of the fixed disk 208. The first spring 209 is sleeved on the outer wall of the fixed rod 205. The reinforcement mechanism is arranged at the top of the moving block 204. When the hoisting unit is conducting an experiment, the frame 103 is directly inserted into the embedded groove 200, and then the moving block 204 is moved. During the movement of the moving block 204, the plug 203 will be extruded, so that the plug 203 moves out of the activity groove 202 and is inserted into the groove on the outer wall of the frame 103, thereby longitudinally positioning the frame 103 in the embedded groove 200. Moreover, a groove adapted to the fixed rod 205 is formed at the top of the moving block 204, so that the fixed rod 205 will not block the movement of the moving block 204, and the moving block 204 can stably move in the first moving cavity 201. At the same time, the first spring 209 is positioned by the fixed disk 208, so that after the moving block 204 moves in the reverse direction, the plug 203 will automatically move in the reverse direction and retract into the activity groove 202, thereby improving the convenience of the installation mechanism.

[0078] Among them, the reinforcement mechanism includes a plug rod 211, an inclined surface 212, a second spring 215, a roller 221 and a synchronization mechanism. At the bottom end of the inner wall of the slot 200, a movable hole 210 is opened. The inside of the movable hole 210 is communicated with the inside of the first movable cavity 201. The outer wall of the plug rod 211 is movably inserted and connected with the inner wall of the movable hole 210. The inclined surface 212 is opened at the top end of the moving block 204. An annular groove 213 is opened on the inner wall of the movable hole 210. A fixed ring 214 is slidably connected to the inner wall of the annular groove 213. The fixed ring 214 is fixedly sleeved on the outer wall of the plug rod 211. The second spring 215 is arranged at the top end of the fixed ring 214. The second spring 215 is sleeved on the outer wall of the plug rod 211. A rotating groove 220 is opened at the bottom end of the plug rod 211. The roller 221 is rotatably connected to the inner wall of the rotating groove 220. The synchronization mechanism is arranged inside the first movable cavity 201. The synchronization mechanism is used for the synchronous movement of the two moving blocks 204. When the moving block 204 moves, the inclined surface 212 will squeeze the roller 221, so that the plug rod 211 rises in the movable hole 210, and the plug rod 211 is inserted into the hole at the bottom end of the frame 103, so as to horizontally position the frame 103 in the slot 200. And a groove adapted to the plug rod 211 is opened on the outer wall of the plug block 203, so that when the plug block 203 is inserted into the groove on the outer wall of the frame 103, it will not be blocked by the plug rod 211. At the same time, through the arrangement of the second spring 215, after the moving block 204 moves in the reverse direction, the plug rod 211 can automatically move down and retract into the movable hole 210, thereby improving the convenience of the reinforcement mechanism.

[0079] Among them, the synchronization mechanism includes a turntable 216, a connecting rod 219 and a servo motor 218. The turntable 216 is rotatably connected to the inner wall of the first movable cavity 201. The end of the connecting rod 219 is rotatably connected to the side of the top end of the turntable 216. The other end of the connecting rod 219 is rotatably connected to the top end of the moving block 204. An installation cavity 217 is opened inside the first base 101. The servo motor 218 is installed inside the installation cavity 217. The output end of the servo motor 218 is drivingly connected to the bottom end of the turntable 216. By driving the turntable 216 to rotate through the operation of the servo motor 218, under the connection of the connecting rod 219, the two moving blocks 204 can move synchronously relative to each other or move away from each other, further improving the convenience of the installation mechanism and the reinforcement mechanism. The servo motor 218 is electrically connected to the external power supply through an external switch, which is convenient for the operator to control the servo motor 218 and improves the safety and convenience of the operation of the servo motor 218.

The rope passing roller 305 is rotatably connected between the two vertical plates 304. A connecting column 306 is fixedly connected to the top of the material box 301, and the connecting ring 307 is arranged at the top of the connecting column 306. The I-shaped block 309 is fixedly connected to the material box 301. Guide grooves 308 are opened on both sides of the fixed frame 302, and the I-shaped block 309 is slidably arranged on the inner wall of the guide groove 308. A rotating cavity 310 is opened in the inner wall of the I-shaped block 309, and the rotating wheel 311 is rotatably connected to the inner wall of the rotating cavity 310. The outer wall of the rotating wheel 311 is attached to the outer wall of the guide groove 308. Pull out the steel wire rope in the machine body 104 and bypass it from the top of the rope passing roller 305 and then connect it to the connecting ring 307. Then add the required amount of water into the material box 301. At this time, the machine body 104 works, and the released steel wire rope is gradually wound up. At the same time, the wound steel wire rope lifts the material box 301 to conduct the load experiment of the machine body 104. A water inlet pipe is arranged at the top of the material box 301, and a baffle is arranged at the top of the water inlet pipe by means of flange connection. Thus, water can be added into the material box 301 through the water inlet pipe, and the baffle blocks the splashing of water, so as to avoid the phenomenon of water spilling out of the material box 301 during the load experiment, thereby improving the working stability of the load component.

[0081] The present invention also provides a winch load experiment method based on a rocker boom centralized control system, including the following steps:

[0082] Step 1: Embed the winch unit to be tested into the embedding groove 200. Then the servo motor 218 works to drive the turntable 216 to rotate counterclockwise. Through the connection of the connecting rod 219, the counterclockwise rotation of the turntable 216 drives the two moving blocks 204 to move towards each other. The movement of the moving block 204 causes the inclined surface 212 to squeeze the roller 221, so that the insertion rod 211 rises, and the insertion rod 211 is inserted out of the movable hole 210 and inserted into the installation hole at the bottom end of the frame 103. The moving block 204 continues to move to squeeze the insertion block 203, so that the insertion block 203 can be moved out of the movable groove 202 and inserted into the outer wall of the frame 103, thereby completing the horizontal and vertical positioning of the frame 103 in the embedding groove 200.

[0083] Step 2: Pull out the steel wire rope in the machine body 104, wind it around from the top of the wire rope roller 305 and connect it with the connecting ring 307. Then add the required amount of water into the material box 301. At this time, the machine body 104 works, and the released steel wire rope is gradually wound up. At the same time, the wound steel wire rope lifts the material box 301 to conduct a load test on the machine body 104;

[0084] Step 3: After the material box 301 is lifted by the work of the machine body 104, the top block 403 moves upward under the elastic action of the third spring 407. The movement of the top block 403 drives the movable plate 402 to move until the movable plate 402 abuts against the top end of the inner wall of the second movable cavity 401, causing the first buffer mechanism to start working. Then the air pump 510 works to continuously inflate the air inlet pipe 511. Then, through the connection of the connecting pipe 512, the gas enters the inside of the inflation cavity 506 and squeezes the top end of the piston plate 508, causing the piston plate 508 to rise. The rise of the piston plate 508 drives the fourth spring 509 to rise and compresses the fourth spring 509. The rise of the fourth spring 509 drives the abutting plate 507 to rise. The rise of the abutting plate 507 drives the connecting rod 504 to rise. The rise of the connecting rod 504 drives the top plate 502 to rise, causing the second buffer mechanism to start working.
