[0033] In this embodiment, when it is necessary to take out the I-beam body 2 placed upright inside the anti-dumping mechanism 1, the controller 111 is first used to close the four electromagnets 117, and then the two servo electric cylinders 106 are started by the controller 111. At this time, one of the started servo electric cylinders 106 will drive the corresponding mounting plate 107 to move vertically upward under the cooperation of the first slider 104 and the corresponding rectangular hole 116. At the same time, the other started servo electric cylinder 106 will drive the corresponding mounting plate 107 to move vertically upward under the cooperation of the second slider 105 and the corresponding rectangular hole 116.

When the second slider 105 moves to the point where it can no longer move, the controller 111 is used to turn off the other motor 108. At this time, the other motor 108 that is turned off will stop the corresponding two electromagnets 117 from moving under the cooperation of the above-mentioned components, and then the controller 111 is used to start one of the motors 108. At this time, the started motor 108 will be on the placement rack 1 01. The corresponding rectangular plate 114, the corresponding cylindrical hole 115 and the first bearing cooperate to drive the first threaded rod 109 to rotate, and the rotating first threaded rod 109 will drive the first slider 104 to move towards the direction close to the motor 108 under the cooperation of the two slide grooves 103. At the same time, the moving first slider 104 will drive the corresponding two electromagnets 117 to move under the cooperation of the corresponding servo electric cylinder 106, the corresponding rectangular hole 116 and the corresponding mounting plate 107. When the first slider 104 moves to the point where it can no longer move, the controller 111 can be used to directly turn off one of the motors 108 (such as Figure 3 The I-beam bodies 2 in the two rectangular grooves 102 can then be lifted and removed by using the prepared crane, slings and other components. When it is necessary to move the two upright I-beam bodies 2 to the interior of the anti-dumping mechanism 1, simply perform the reverse operation according to the above steps.

[0034] Embodiment 2: According to Figure 1-Figure 9 As shown, the anti-dumping mechanism 1 is provided with an auxiliary mechanism 3, which includes an air pump 301, two guide holes 305, two auxiliary holes 306 and two discharge holes 309. A filter plate 302 is installed at the air inlet end of the air pump 301, a three-way pipe 303 is installed at the air outlet end of the air pump 301, and hoses 304 are installed at both air outlet ends of the three-way pipe 303. A round tube 307 is fixedly sleeved inside each auxiliary hole 306, and a guide shell 308 is installed at the air outlet end of each round tube 307. The air pump 301 is electrically connected to the controller 111, and the air outlet ends of the two hoses 304 are movable through the placement rack. On one side of 101, the air outlet end of each hose 304 is movably connected to the inside of each guide hole 305, and the air outlet end of each hose 304 is installed with the air inlet end of each round tube 307 respectively. The two guide holes 305 are both opened on one side of the second slider 105 near the bottom position, and the two auxiliary holes 306 are both opened on one side of the first slider 104 near the bottom position, each guide shell 308 is respectively located inside each slide groove 103, and each discharge hole 309 is respectively opened on one side of each rectangular plate 114, and the interior of each discharge hole 309 is respectively connected with the interior of each slide groove 103.

[0035] In this embodiment, when it is necessary to remove large particles such as stones accumulated inside the chute 103 (such as Figure 3In the state shown, there are large particles accumulated inside the two chutes 103), at this time, the air pump 301 is first started by the controller 111, and the started air pump 301 will, with the cooperation of the filter plate 302, draw air from the environment into the inside of the air pump 301, and filter out particles such as dust mixed in the air, and then transport it to the inside of the three-way pipe 303, and then transport it to the inside of the two hoses 304, and then with the cooperation of the corresponding guide holes 305 and the corresponding auxiliary holes 306, transport it to the inside of the two round tubes 307, and then transport it to the inside of the two guide shells 308, and then spray it from the air outlet ends of the two guide shells 308. When air is sprayed from the air outlet ends of the two guide shells 308, the controller 111 is used to start one of the motors 108. At this time, the started motor 108 can, with the cooperation of the above-mentioned components, drive the first slider 104 to move towards the direction close to the rectangular plate 114 for water The first slider 104 moves horizontally, and the horizontally moving first slider 104 will drive the two guide shells 308 and the air outlet ends of the two hoses 304 to move with the cooperation of the two auxiliary holes 306 and the two circular tubes 307. At this time, with the cooperation of the two discharge holes 309 and the two guide shells 308 that move horizontally and spray gas at the air outlet ends, the large particles accumulated in the two chutes 103 can be cleared. When the two guide shells 308 are moved to the point where they can no longer move, the air pump 301 is turned off by the controller 111, and then the first slider 104 is reset by the cooperation of the controller 111 and one of the motors 108 (when the first slider 104 is reset, it is necessary to manually cooperate with the movement of the first slider 104 to slowly move the two hoses 304 out of the inside of the two chutes 103 respectively). When the first slider 104 is reset to its original position, one of the motors 108 can be directly turned off by the controller 111.

[0036] The effect and working principle of the whole mechanism are as follows: when it is necessary to take out the I-beam body 2 placed upright inside the anti-dumping mechanism 1, the four electromagnets 117 are first turned off by the controller 111, and then the two servo electric cylinders 106 are started by the controller 111. At this time, one of the started servo electric cylinders 106 will drive the corresponding mounting plate 107 to move vertically upward under the cooperation of the first slider 104 and the corresponding rectangular hole 116, and at the same time, the other started servo electric cylinder 106 will drive the corresponding mounting plate 107 to move vertically upward under the cooperation of the second slider 105 and the corresponding rectangular hole 116. At the same time, the two moving parts are The vertically upwardly moving mounting plates 107 will drive the corresponding two electromagnets 117 to move vertically upward. When the four electromagnets 117 are moved to the point where they can no longer move, each I-beam body 2 is separated from the corresponding two electromagnets 117. At the same time, the two servo electric cylinders 106 are closed by the controller 111. Then, the controller 111 is used to start another motor 108. At this time, the started motor 108 will drive the second threaded rod 110 to rotate under the cooperation of the placement rack 101, the corresponding rectangular plate 114, the corresponding cylindrical hole 115 and the second bearing. The rotating second threaded rod 110 will rotate under the cooperation of the two slide grooves 103. The second slider 105 is driven to move in the direction close to the motor 108. At the same time, the moving second slider 105 will drive the corresponding two electromagnets 117 to move together with the cooperation of the corresponding servo electric cylinder 106, the corresponding rectangular hole 116 and the corresponding mounting plate 107. When the second slider 105 moves to the point where it can no longer move, the controller 111 is used to turn off the other motor 108. At this time, the other motor 108 that is turned off will stop the corresponding two electromagnets 117 from moving with the cooperation of the above-mentioned components. Then, the controller 111 is used to start one of the motors 108. At this time, the started motor 108 will stop moving when the second slider 105 is put. The rack 101, the corresponding rectangular plate 114, the corresponding cylindrical hole 115 and the first bearing cooperate to drive the first threaded rod 109 to rotate, and the rotating first threaded rod 109 will drive the first slider 104 to move towards the direction close to the motor 108 under the cooperation of the two slide grooves 103. At the same time, the moving first slider 104 will drive the corresponding two electromagnets 117 to move under the cooperation of the corresponding servo electric cylinder 106, the corresponding rectangular hole 116 and the corresponding mounting plate 107. When the first slider 104 moves to a point where it can no longer move, the controller 111 can be used to directly turn off one of the motors 108 (such as Figure 3The state shown in the figure) is then achieved by using the prepared crane and slings and other components to lift and remove the I-beam bodies 2 in the two rectangular grooves 102. When it is necessary to move the two upright I-beam bodies 2 to the interior of the anti-dumping mechanism 1, the above-mentioned operation steps can be directly reversed. When it is necessary to remove large particles such as stones accumulated in the chute 103 (such as Figure 3 In the state shown, there are large particles accumulated inside the two chutes 103), at this time, the air pump 301 is first started by the controller 111, and the started air pump 301 will, with the cooperation of the filter plate 302, draw air from the environment into the inside of the air pump 301, and filter out particles such as dust mixed in the air, and then transport it to the inside of the three-way pipe 303, and then transport it to the inside of the two hoses 304, and then with the cooperation of the corresponding guide holes 305 and the corresponding auxiliary holes 306, transport it to the inside of the two round tubes 307, and then transport it to the inside of the two guide shells 308, and then spray it from the air outlet ends of the two guide shells 308. When air is sprayed from the air outlet ends of the two guide shells 308, the controller 111 is used to start one of the motors 108. At this time, the started motor 108 can, with the cooperation of the above-mentioned components, drive the first slider 104 to move towards the direction close to the rectangular plate 114 for water The first slider 104 moves horizontally, and the horizontally moving first slider 104 will drive the two guide shells 308 and the air outlet ends of the two hoses 304 to move with the cooperation of the two auxiliary holes 306 and the two circular tubes 307. At this time, with the cooperation of the two discharge holes 309 and the two guide shells 308 that move horizontally and spray gas at the air outlet ends, the large particles accumulated in the two chutes 103 can be cleared. When the two guide shells 308 are moved to the point where they can no longer move, the air pump 301 is turned off by the controller 111, and then the first slider 104 is reset by the cooperation of the controller 111 and one of the motors 108 (when the first slider 104 is reset, it is necessary to manually cooperate with the movement of the first slider 104 to slowly move the two hoses 304 out of the inside of the two chutes 103 respectively). When the first slider 104 is reset to its original position, one of the motors 108 can be directly turned off by the controller 111.
