Description

Technical Field

[0001] The invention relates to the field of ship loader chutes, and in particular to a ship loader chutes anti-collision device and a use method thereof. Background Art

[0002] Ship loaders are large bulk material machines used for loading at bulk material terminals. Generally, ship loaders are composed of arm belt conveyors, transition belt conveyors, telescopic chute, tail car, running device, gantry, tower, pitch device, slewing device, etc. Hard materials are transported into the ship's hold through the chute.

[0003] At least the following problems have not been solved in the prior art: when the ship loader is loading materials through the telescopic chute, it is necessary to load materials into different cargo bins. Therefore, during the movement of the telescopic chute, the upwardly moving chute pipe head may collide with the edge of the material port of the cargo bin, causing damage to the chute pipe head. Therefore, it is necessary to protect the edge of the chute. The current ship loader chute anti-collision device is to set a buffer protection structure on the outer wall of the chute. However, after the chute contacts the edge of the cargo bin, although the buffer protection structure has a certain buffering effect, the chute will still be subjected to a certain horizontal impact force, and it is difficult to effectively reduce the collision impact force on the chute. Therefore, a collision prevention device is needed that can effectively reduce the impact force on the chute. Summary of the invention

[0007] Preferably, the release mechanism includes a first connecting block, the first connecting block is fixedly connected to the extended end of the connecting telescopic rod, a pushing rod is hinged on the inner wall of the first connecting block, one end of the pushing rod is hinged on the second connecting block, a support frame is fixedly connected to the bottom of the second connecting block, a one-way roller is fixedly connected to the inside of the support frame, a buffer bin is tightly fitted on the outer wall of the second connecting block, the buffer bin is fixedly connected to the external cylinder, vertical grooves are opened on both sides of the inner wall of the buffer bin, and the one-way roller abuts against the inner wall of the vertical grooves.

[0008] Preferably, the moving assembly includes a mounting block, which is fixedly connected to the external cylinder, one side of the mounting block is fixedly connected to a spring telescopic rod, one end of the spring telescopic rod is fixedly connected to an arc plate, the middle part of the arc plate is fixedly connected to the sliding bin, and the lower end of the arc plate is fixedly connected to the pushing tooth plate.

[0009] Preferably, a limiting rod passes through the interior of the sleeve ring, and a positioning cylinder is fixedly connected to the upper end of the limiting rod, and the positioning cylinder is fixedly sleeved on the slide tube.

[0010] Preferably, a mounting ring is fixedly installed on the middle outer wall of the chute pipe, a docking ring is fixedly connected to the upper end of the chute pipe, a mounting frame for mounting on a ship loader is fixedly connected to the outer wall of the docking ring, a square groove is provided at the upper end of the mounting frame, screw holes are provided inside the square groove, and a switch sensor is fixedly connected to the outer wall of the mounting ring.

[0011] Preferably, the method for using the ship loader chute anti-collision device comprises the following steps: S1: First, the mounting frame is fixed on the arm of the ship loader, and then the chute pipe is adjusted and moved by the ship loader. During the movement of the chute pipe, the fitting baffle at the bottom can contact the surface of the obstacle, and at the same time drive the fitting baffle and the six-fold rod connected to it to move toward the middle. Since the slider connected to the fitting baffle is limited and slides inside the sliding bin, when it is pushed, the three fitting baffles are simultaneously stuck to the surface of the obstacle, prompting the fitting baffle and the six-fold rod to evenly distribute the thrust they receive; S2: After the three fitting baffles contact the obstacle, the continuous pushing force they receive drives the connecting telescopic rod to retract, so that the first connecting block connected to the outer wall moves toward the middle at the same time, so that when it is pushed again, it can push the second connecting block to slide in the buffer bin with resistance through the connected pushing rod. At the same time, the one-way roller connected to the support frame at the lower end of the second connecting block rotates on the surface of the vertical groove, so that it cooperates with the connected buffer mechanism to buffer the impact force, and at the same time continues to drive the arc plate to push toward the middle, so that the arc plate pushes the spring telescopic rod to compress, and the lower end synchronously drives The toothed plate is pushed to move, so that the toothed plate drives the transmission gear and the driving gear to rotate while being pushed, so that the driving gear rotates and drives the gear ring cylinder to rotate, and at the same time, the rotating gear ring cylinder drives the surrounding driving gears to rotate, forming an iris rotating mechanism, which converts and buffers the extrusion impact force of the three fitting baffles, and makes the gear ring cylinder rotate and move upward on the sliding groove outside the chute tube, so that the tube head at the lower end of the chute tube moves up, and at the same time drives the connected gear ring cylinder to move up, and adjusts the height of the lifting mechanism to prevent the chute tube from being subjected to horizontal impact force; S3: After the fitting baffle passes the obstacle, the compressed spring telescopic rod is released, and the arc plate and the fitting baffle are released at the same time. When resetting, the second connecting block inside the buffer bin moves by friction, so that the one-way roller on the connecting support frame stops rotating when it contacts the inner wall of the vertical groove for resetting, thereby increasing the resistance during resetting, avoiding the end of the chute pipe from falling too fast and colliding with the obstacle, causing damage to the end of the chute pipe, and at the same time reducing the descending and resetting speed of the lifting mechanism. When the chute pipe moves to the second cargo hold, the chute pipe slowly moves down to open the opening, completing the warehouse transfer operation.

[0012] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, the height of the tube head of the chute pipe is raised by a lifting mechanism. When the position of the chute pipe is adjusted, the buffer mechanism of the tube head will contact the surface of the obstacle, so that it is pushed to push the moving component toward the middle. At this time, an iris rotating structure is formed inside the lifting mechanism, so that the lifting mechanism rotates on the chute pipe, driving the tube head of the chute pipe to move upward when it contacts the obstacle, to perform evasive protection, to prevent the tube head from being directly hit, and through the upward movement of the tube head of the chute pipe, the lateral impact force it is subjected to is converted into its upward force, and the horizontal impact force it is subjected to is converted, thereby further reducing the impact force it is subjected to.

[0013] In the present invention, when the buffer mechanism contacts the surface of the obstacle, multiple fitting baffles can be adjusted to increase the contact area of ​​the obstacle surface, so that the contact area can be diffused during collision and the purpose of buffering can be achieved. When the fitting baffle contacts, the lifting mechanism is used to push it upward to avoid direct collision that causes bending and damage to the chute tube.

[0014] In the present invention, the release mechanism reduces the friction when the lifting mechanism moves upward, and the chute pipe can slowly move downward when passing through an obstacle, so that the friction of the bottom contact of the chute pipe is reduced when passing through the obstacle, thereby reducing the wear of the bottom pipe head of the chute pipe.

[0025] The use method and advantages of the present invention: The use method of the ship loader chute anti-collision device has the following working process: like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown: S1: First, the mounting frame 10 is fixed on the arm of the ship loader, and then the chute tube 1 is adjusted and moved by the ship loader. During the movement of the chute tube 1, the fitting baffle 36 at the bottom can contact the surface of the obstacle, and at the same time drive the fitting baffle 36 and the six-fold rod 34 connected thereto to move toward the middle. Since the slider 37 connected to the fitting baffle 36 is limited and slides inside the sliding bin 33, when it is pushed, the three fitting baffles 36 are simultaneously stuck to the surface of the obstacle, so that the fitting baffle 36 and the six-fold rod 34 evenly distribute the thrust they receive; S2: After the three fitting baffles 36 contact the obstacle, the continuous pushing force drives the connecting telescopic rod 32 to retract, so that the first connecting block 41 connected to the outer wall moves toward the middle at the same time, so that when it is pushed again, it can push the second connecting block 43 to slide in the buffer bin 46 through the connected pushing rod 42, and at the same time, the one-way roller 45 connected to the support frame 44 at the lower end of the second connecting block 43 rotates on the surface of the vertical groove 47, so that it cooperates with the connected buffer mechanism 3 to buffer the impact force, and at the same time continues to drive the arc plate 53 to push toward the middle, so that the arc plate 53 pushes the spring telescopic rod 52 to compress, and the lower end synchronously drives The toothed plate 22 is pushed to move, so that the toothed plate 22 drives the transmission gear 23 and the driving gear 24 to rotate while being pushed, so that the driving gear 24 rotates while driving the ring gear cylinder 25 to rotate, and the rotating ring gear cylinder 25 drives the surrounding driving gears 24 to rotate, forming an iris rotating mechanism, which converts and buffers the extrusion impact force of the three fitting baffles 36, and makes the ring gear cylinder 25 rotate and move upward on the sliding groove 12 outside the chute tube 1, so that the pipe head at the lower end of the chute tube 1 moves up, and at the same time drives the connected ring gear cylinder 25 to move up, and adjusts the height of the lifting mechanism 2 to prevent the chute tube 1 from being subjected to horizontal impact force; S3: After the fitting baffle 36 passes the obstacle, the compressed spring telescopic rod 52 is released, and the arc plate 53 and the fitting baffle 36 are released at the same time. When resetting, the second connecting block 43 inside the buffer bin 46 moves by friction, so that the one-way roller 45 on the connecting support frame 44 stops rotating when it contacts the inner wall of the vertical groove 47 for resetting, thereby increasing the resistance during resetting, preventing the end of the chute pipe 1 from falling too fast and colliding with the obstacle, thereby causing damage to the end of the chute pipe 1, and at the same time reducing the descending and resetting speed of the lifting mechanism 2. When the chute pipe 1 moves to the second cargo hold opening, the chute pipe 1 slowly moves down to open the opening, completing the warehouse opening transfer operation.
