DETAILED DESCRIPTION

[0042] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0043] The laser ranging sensor in the related technology is susceptible to on-site interference, which leads to the technical problem of false detection of laser ranging. The reason for this problem is that when the loader is unloading, although the chute is lowered close to the bottom of the ship, dust is still inevitably generated after unloading. The dust will affect the accuracy of laser ranging and lead to the problem of false detection of laser ranging.

[0044] In view of the above technical problems, the embodiments of the present application provide a ship loader chute anti-bottoming system, a ship loader and an anti-bottoming method, by arranging the detection end of the telescopic member below the chute bottom, so that the telescopic member touches the ship bottom before the chute bottom, thereby realizing the chute anti-bottoming. And the trigger connected to the telescopic member controls the telescopic member to be retracted above the chute bottom after the chute touches the bottom, so as to avoid the material after unloading from damaging the telescopic member and not affecting the normal operation of the ship loader.

[0045] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0046] refer to Figure 1 The present application provides a ship loader chute anti-bottoming system, which includes a chute 10 and a telescopic mechanism 20. The telescopic mechanism 20 is installed on the chute 10. For example, the telescopic mechanism 20 can be installed on the outer peripheral side wall of the chute 10.

[0047] like Figure 2As shown, the telescopic mechanism 20 includes a lifting module 21, a telescopic member 22 and a trigger 23. The lifting module 21 is a driving source in the telescopic mechanism 20, and the lifting module 21 is used to drive the telescopic member 22 to move toward the bottom of the ship or move away from the bottom of the ship. The lifting module 21 can be a device that can provide power, such as a motor, a pneumatic cylinder or a hydraulic cylinder, and this application does not limit it.

[0048] refer to Figure 1 and Figure 2 The lifting module 21 is installed on the chute 10, for example, the lifting module 21 is installed in the innermost layer of the chute 10, so that the lifting module 21 can be lowered synchronously with the chute 10 during the step-by-step lowering process of the chute 10.

[0049] refer to Figure 2 The telescopic member 22 is connected to the lifting module 21, and the telescopic member 22 is connected to the output end of the lifting module 21, so that the lifting module 21 can drive the telescopic member 22 to move. The telescopic member 22 has a detection end 221 and a connection end 222, wherein the detection end 221 is the end close to the bottom of the ship, and the connection end 222 is the end away from the bottom of the ship. The detection end 221 is located below the bottom of the chute 10, so that the detection end contacts the bottom of the ship before the chute 10, thereby preventing the chute 10 from touching the bottom. The detection end 221 of the telescopic member 22 can be cylindrical, square or ring-shaped, and this application does not limit it.

[0050] refer to Figure 2 , the connection end 222 is connected to the trigger 23. When the trigger 23 receives the first signal, the chute 10 stops lowering to prevent the chute 10 from touching the bottom, and then the telescopic member 22 is recovered through the lifting module 21. When the trigger 23 receives the second signal, the telescopic member 22 retracts to the bottom of the chute 10. This prevents the first signal and the second signal from being transmitted to the trigger 23 through the external controller. The specific communication method can be wired communication or wireless communication. The telescopic member 22 is recovered to the bottom of the chute 10 to prevent the material after unloading from damaging the telescopic member 22. Then the chute 10 can be unloaded normally without affecting the normal operation of the ship loader.

[0051] The ship loader chute anti-bottoming system provided in the present application is connected to the lifting module 21 through the telescopic member 22, so that the lifting module 21 can drive the telescopic member 22 to move toward the bottom of the ship or move away from the bottom of the ship. Since the detection end 221 of the telescopic member 22 is located below the bottom of the chute 10, the telescopic member 22 contacts the bottom of the ship before the chute 10 during the lowering process of the chute 10, thereby preventing the chute 10 from touching the bottom.

[0052] When the telescopic member 22 abuts against the bottom of the ship, the telescopic member 22 moves away from the bottom of the ship. Since the trigger 23 is connected to the connecting end 222 of the telescopic member 22, the telescopic member 22 can drive the trigger 23 to move away from the bottom of the ship. When the trigger 23 receives the first signal, the chute 10 stops lowering to place the chute 10 in the working position. The telescopic member 22 is driven back to the bottom of the ship by the lifting module 21. When the trigger 22 receives the second signal, the telescopic member 22 retracts to above the bottom of the chute 10, and the telescopic member 22 stops moving to avoid damage to the telescopic member 22 by the material after the chute 10 is unloaded.

[0053] In some embodiments, reference Figure 2 The telescopic mechanism 20 further includes a first travel switch 24 and a second travel switch 25. The first travel switch 24 is located on the trigger 23, and the second travel switch 25 is located on the first travel switch 24. Both the first travel switch 24 and the second travel switch 25 can be installed on the outer periphery of the chute.

[0054] When the telescopic member 22 drives the trigger 23 to trigger the first travel switch 24 , the first travel switch 24 sends a first signal to the trigger 23 to stop the chute 10 from being lowered and drives the telescopic member 22 to retract through the lifting module 21 .

[0055] When the telescopic member 22 drives the trigger 23 to trigger the second travel switch 25 , the second travel switch 25 sends a second signal to the trigger 23 to retract the telescopic member 22 to the bottom of the chute 10 .

[0056] refer to Figure 2 In some embodiments, the lifting module 21 includes a housing 211, a lead screw 212 and a slide 213. The housing 211 is mounted on the chute 10, the lead screw 212 is mounted in the housing 211, the slide 213 is sleeved on the lead screw 212, and the telescopic member 22 is inserted into the slide 213, for example, the telescopic member 22 is inserted into the sliding bearing in the slide 213.

[0057] When lowering the chute 10, the lead screw 212 is rotated to move the slide 213 and the telescopic member 22 downward, so that the detection end 221 of the telescopic member 22 is located below the chute 10. When the telescopic member 22 contacts the bottom of the ship, the telescopic member 22 moves upward under the action of the bottom of the ship.

[0058] It should be noted that the lifting module 21 may further include a spring 214 , and the spring 214 is connected to the telescopic member 22 . During the telescopic process of the telescopic member 22 , the spring 214 plays a buffering role.

[0059] refer to Figure 1 and Figure 2In some embodiments, the ship loader chute bottoming prevention system further includes a drum 30, which is connected to the chute 10, and an armored cable 40 is wound between the drum 30 and the chute 10. The drum 30 lowers and recovers the chute 10 through the armored cable 40. The armored cable 40 can carry the chute 10, and supply power and transmit signals to mechanisms such as the upgrade module installed on the chute 10.

[0060] refer to Figure 1 In some embodiments, a conductive slip ring 31 is installed on the reel 30. The conductive slip ring 31 is an electric rotary connector that can realize continuous transmission of signals and data between two relatively rotating mechanisms. The armored cable 40 has wires and signal wires. The wires are electrically connected to the conductive slip ring 31, and the signal wires are signal-connected to the conductive slip ring. The conductive slip ring 31 supplies power to the armored cable 40 and transmits signals.

[0061] In some embodiments, the lifting module 21 is electrically connected to the wire, so as to power the lifting module 21. The lifting module 21 and the trigger 23 are both connected to the signal line signal, so as to realize the signal transmission between the lifting module 21 and the trigger 23.

[0062] In some embodiments, a distance measuring sensor is also included. The distance measuring sensor is installed on the chute 10. The distance measuring sensor is connected to the armored cable 40 for signal. The distance measuring sensor can detect the distance between the chute 10 and the bottom of the ship. The distance measuring sensor can be used as an auxiliary anti-bottoming device to further improve the safety of anti-bottoming.

[0063] In some embodiments, there are multiple telescopic mechanisms 20, such as two, three, four or more. Multiple telescopic mechanisms 20 are arranged at equal intervals along the periphery of the chute 10, so that anti-bottoming protection is achieved through each telescopic mechanism 20 to prevent the chute 10 from tilting to one side.

[0067] B. When the telescopic member 22 touches the bottom of the ship, the telescopic member 22 drives the trigger 23 to move in a direction away from the bottom of the ship.

[0068] C. When the trigger 23 receives the first signal, the chute 10 stops lowering, and the lifting module 21 drives the telescopic member 22 to continue moving in a direction away from the bottom of the ship.

[0069] D. When the trigger 23 receives the second signal, the telescopic member 22 retracts to above the bottom of the chute 10, and the telescopic member 22 stops moving.
