Description

Technical Field

[0001] This application relates to the technical field of safety protection for port loading and unloading equipment, and in particular to an anti-collision auxiliary device for a ship unloader. Background Technology

[0002] Ship unloaders are important equipment used in ports and docks to unload cargo from ships. Their working principle mainly utilizes grabs that can continuously transport bulk cargo from the ship's hold to the boom, and in conjunction with the unloading hoppers set on the bulge, transfers the cargo to the conveyor below the unloading hoppers.

[0003] The two parallel side plates on the hopper are usually flipped. The side plate closer to the cargo ship is the front flip plate, and the side plate farther away from the cargo ship is the rear flip plate. When unloading, the front flip plate flips to a horizontal state, thus forming a feed inlet on one side of the hopper. The grab bucket can enter the hopper from the feed inlet and unload the clamped material, which falls onto the conveyor below through the hopper.

[0004] In related technologies, since the grab bucket is hoisted by means of steel wire rope, it will sway continuously during the movement. When the surrounding wind is strong or the grab bucket moves too fast, the grab bucket entering the unloading hopper may collide with the rear flap of the unloading hopper, which will not only affect the unloading speed, but may also bring safety hazards. Utility Model Content

[0005] To prevent the grab bucket from directly impacting the side wall of the unloading hopper during operation, this application provides an anti-collision auxiliary device for the unloading machine.

[0006] This application provides a collision avoidance auxiliary device for a ship unloader, which adopts the following technical solution:

[0007] A collision avoidance auxiliary device for a ship unloader includes a positioning frame disposed within a hopper. The positioning frame includes a first plate parallel to a rear tilting plate and second plates disposed on both sides of the first plate. A buffer plate is slidably disposed between the two second plates. The buffer plate is located on the side of the first plate facing the grab bucket. A plurality of first springs are arranged in an array between the buffer plate and the first plate. The second plates are also provided with a positioning component and an unlocking component. When the buffer plate moves toward the first plate, the positioning component can restrict the buffer plate from sliding in the opposite direction from the first plate. The unlocking component can unlock the restriction imposed on the buffer plate by the positioning component.

[0008] By adopting the above technical solution, when the grab bucket impacts the buffer plate, the first spring can provide a buffering effect when the grab bucket contacts the rear buffer plate, reducing the impact force; that is, it can prevent the grab bucket from directly impacting the rear flap plate under violent shaking, and at the same time, it can improve the efficiency of the grab bucket and enhance the stability of the grab bucket during unloading.

[0009] Optionally, guide blocks are provided at both ends of the buffer plate, and guide grooves are provided on the side wall of the second plate for the guide blocks to slide.

[0010] By adopting the above technical solution, the guide block slides in the guide groove, ensuring the stability and directionality of the buffer plate during the sliding process.

[0011] Optionally, the positioning component includes a positioning block and a second spring. A groove is provided on the side wall of the second plate for the positioning block to slide. The second spring is disposed between the bottom wall of the groove and the positioning block. The extension direction of the groove is perpendicular to the sliding direction of the buffer plate. A chamfer is provided on the side of the positioning block away from the first plate. When the buffer plate slides toward the first plate, the buffer plate abuts against the chamfer of the positioning block.

[0012] By adopting the above technical solution, when the buffer plate is impacted and slides towards the first plate, the positioning block is pushed by the chamfer and reset by the elastic force of the second spring, thus restricting the reverse sliding of the buffer plate and realizing the automatic positioning and locking of the buffer plate.

[0013] Optionally, a limiting block is provided on the outer wall of the positioning block, and the second plate has a limiting groove on the side wall of the slide groove for the limiting block to slide.

[0014] By adopting the above technical solution, the limiting block slides within the limiting groove, restricting the movement range of the positioning block and preventing the positioning block from detaching from the groove.

[0015] Optionally, the unlocking component includes an unlocking rod, a connecting rod, and a power component. One end of the unlocking rod is slidably inserted into the positioning block. The end of the unlocking rod inserted into the positioning block is provided with an anti-detachment block. The positioning block has a movable groove for the anti-detachment block to slide. The unlocking rod and the positioning block are arranged in a one-to-one correspondence. The other end of the unlocking rod passes through the second spring and is connected to the connecting rod. The power component can drive the connecting rod to slide towards or away from the positioning block.

[0016] By adopting the above technical solution, the power component drives the linkage rod to slide, which in turn drives the unlocking rod and the positioning block to slide, thereby realizing the function of unlocking the buffer plate.

[0017] Optionally, the power component includes a motor and a screw, the motor is connected to one end of the screw, and the other end of the screw passes through the connecting rod and is threadedly connected to the connecting rod.

[0018] By adopting the above technical solution, the motor drives the screw to rotate, and the connecting rod slides through the threaded connection.

[0019] Optionally, mounting blocks are provided on the two opposite side walls of the second plate, and mounting grooves for the mounting blocks to slide into are opened from top to bottom on the upper surface of the two side plates of the hopper.

[0020] By adopting the above technical solution, the mounting block is slidably inserted into the mounting groove, realizing a stable connection between the positioning frame and the hopper, and improving the installation convenience and stability of the device.

[0021] Optionally, the hopper has a placement groove at the lower end of the mounting groove, and the placement groove is located on the side of the mounting groove near the rear flap.

[0022] By adopting the above technical solution, when the mounting block slides to the lower end of the mounting groove, it falls into the positioning groove, which can restrict the upward sliding of the mounting block and achieve more stable positioning.

[0023] Optionally, a mounting plate can be detachably installed on the hopper, and the mounting plate can be inserted into the mounting groove.

[0024] Optionally, the mounting plate is fixed to the hopper by locking bolts.

[0025] By adopting the above technical solution, the mounting plate can be inserted into the mounting slot and fixed to the hopper by locking bolts, realizing the quick installation and disassembly of the device and improving the stability of the anti-collision auxiliary device during installation.

[0026] Optionally, a buffer pad is provided on the side wall of the buffer plate opposite to the first plate.

[0027] In summary, this application includes at least one of the following beneficial effects:

[0028] 1. The combination of the buffer plate and the first spring can buffer the grab bucket that shakes violently, preventing the grab bucket from directly hitting the rear tipping plate and improving the safety of the ship unloader during operation;

[0029] 2. Through the cooperation of the positioning and unlocking components, the grab bucket can effectively dissipate energy, reduce the shaking degree of the grab bucket when it hits the buffer plate, and improve the accuracy and stability during unloading. Attached Figure Description

Detailed Implementation

[0036] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0037] This application discloses an anti-collision auxiliary device for a ship unloader. (Refer to...) Figure 1 The ship unloader includes a boom 101, a main beam 102 mounted on the upper end of the boom 101, a control vehicle 103 that reciprocates and slides on the main beam 102, a grab bucket 104 mounted below the control vehicle 103, and a discharge bucket 105 fixed to the boom 101. The grab bucket 104 is hoisted onto the control vehicle 103 by means of steel wire ropes, etc. The two side plates of the discharge bucket 105 facing the active side can be flipped, with the one closer to the grab bucket 104 being the front flip plate 106 and the one farther away from the grab bucket 104 being the rear flip plate 107. The anti-collision auxiliary device of this application is detachably installed inside the discharge bucket 105 and installed on the side of the rear flip plate 107 facing the grab bucket 104, thereby preventing the grab bucket 104 from directly impacting the rear flip plate 107 under violent shaking.

[0038] Reference Figure 1 and Figure 2In this embodiment, the anti-collision auxiliary device includes a positioning frame 1 disposed within the hopper. The positioning frame 1 includes a first plate 11 parallel to the rear tilting plate and second plates 12 disposed on both sides of the first plate 11. A buffer plate 2 is slidably disposed between the two second plates 12. The buffer plate 2 is located on the side of the first plate 11 facing the grab bucket 104. A plurality of first springs 3 are arranged in an array between the buffer plate 2 and the first plate 11, forming a buffer cavity between the first plate 11, the two second plates 12, and the buffer plate 2. A positioning component 4 and an unlocking component 5 are also disposed on the second plate 12. When the buffer plate 2 moves toward the first plate 11, the positioning component 4 can restrict the buffer plate 2 from sliding in the opposite direction from the first plate 11; the unlocking component 5 can unlock the restriction of the positioning component 4 on the buffer plate 2. More preferably, a buffer pad 7 is fixed on the side wall of the buffer plate 2 away from the buffer cavity. The buffer pad 7 can be made of rubber material, which has good shock absorption performance and can further reduce the impact force generated by the collision.

[0039] When the buffer plate 2 is impacted by the grab bucket 104 and slides towards the first plate 11, the first spring 3 provides a buffering force to reduce the impact speed of the grab bucket 104. When the grab bucket 104 moves to the farthest distance, the positioning component 4 can fix the buffer plate 2 to prevent the buffer plate 2 from moving in the opposite direction under the reaction force of the first spring 3. After the grab bucket 104 successfully unloads material in the discharge hopper 105, it slides out of the discharge hopper 105. At this time, the unlocking component 5 can unlock the restriction of the positioning component 4 on the buffer plate 2, and the buffer plate 2 slides back to its original position under the action of the first spring 3.

[0040] Reference Figure 2 and Figure 3 Specifically, in this embodiment, the positioning component 4 includes a positioning block 41 and a second spring 42. A groove 122 for sliding the positioning block 41 is provided on the side wall of the second plate 12. The second spring 42 is disposed between the bottom wall of the groove 122 and the positioning block 41. The extension direction of the groove 122 is perpendicular to the sliding direction of the buffer plate 2. The positioning block 41 has a chamfer on the side away from the first plate 11. When the buffer plate 2 slides towards the first plate 11, the buffer plate 2 abuts against the chamfer of the positioning block 41, which can drive the positioning block 41 to slide into the groove 122. After the buffer plate 2 passes the positioning block 41, the positioning block 41 slides out of the groove 122 again under the action of the second spring 42, thereby restricting the buffer plate 2 from sliding away from the first plate 11.

[0041] Reference Figure 3 and Figure 4In a further preferred embodiment, a limiting block 411 is fixed on the outer wall of the positioning block 41, and a limiting groove 123 is opened on the side wall of the slide groove 122 for the limiting block 411 to slide. The limiting groove 123 is connected to the slide groove 122. When the limiting block 411 abuts against the side wall of the limiting groove 123 near the buffer cavity, the chamfered part of the positioning block 41 extends into the buffer cavity. When the limiting block 411 slides against the side wall of the limiting groove 123 away from the buffer cavity, the positioning block 41 is completely retracted into the slide groove 122.

[0042] Reference Figure 4 and Figure 5 The unlocking component 5 includes an unlocking rod 51, a connecting rod 52, and a power component 53. The unlocking rod 51 can be a round rod. One end of the unlocking rod 51 is slidably inserted into the positioning block 41. The end of the unlocking rod 51 inserted into the positioning block 41 is provided with an anti-detachment block 511. The anti-detachment block 511 can also be circular in cross-section, and its diameter is larger than that of the unlocking rod 51. The positioning block 41 has a movable groove 412 for the anti-detachment block 511 to slide. The unlocking rod 51 and the positioning block 41 are arranged in a one-to-one correspondence. The other end of the unlocking rod 51 passes through the second spring 42 and is connected to the connecting rod 52. Correspondingly, the second plate 12 also has a corresponding groove for the unlocking rod 51 and the connecting rod 52 to slide. The power component 53 can drive the connecting rod 52 to slide towards or away from the positioning block 41. The power component 53 includes a motor 531 and a screw 532. The motor 531 is connected to one end of the screw 532, and the other end of the screw 532 passes through the connecting rod 52 and is threadedly connected to the connecting rod 52.

[0043] When the chamfered portion of the positioning block 41 is located in the buffer cavity, the anti-detachment block 511 abuts against the side wall of the movable groove 412 away from the buffer cavity; when the positioning block 41 slides in the slide groove 122, the anti-detachment block 511 can slide in the movable groove 412; when it is necessary to unlock the positioning assembly 4, the motor 531 is started, the screw 532 is driven to rotate, and the connecting rod 52 is driven to slide away from the buffer cavity, so that all the positioning blocks 41 can be driven to slide into the slide groove 122 through the unlocking rod 51. At this time, the buffer plate 2 can slide to the side away from the first plate 11 under the action of the first spring 3.

[0044] Reference Figure 2 and Figure 3 Both ends of the buffer plate 2 are fixed with guide blocks 21. The guide blocks 21 can be rectangular or T-shaped, etc., and the side wall of the second plate 12 is provided with guide grooves 121 for the guide blocks 21 to slide. This design ensures that the buffer plate 2 maintains linear motion during sliding, preventing it from shifting when impacted and improving the buffering effect. In a specific configuration, the positioning block 41 can be set in the middle of the second plate 12, while the second guide blocks 21 can be set at the upper and lower ends of the buffer plate 2 respectively.

[0045] Reference Figure 2 and Figure 3 Furthermore, to facilitate the removal of the anti-collision auxiliary device, the positioning frame 1 is designed as a detachable structure. Specifically, mounting blocks 13 are fixed on the two parallel side walls of the second plate 12, and mounting grooves 108 are provided on the upper surfaces of the two side plates of the hopper 105 for the mounting blocks 13 to slide downwards. When the mounting blocks 13 slide into the mounting grooves 108, the anti-collision auxiliary device of the positioning frame 1 can be quickly installed on the hopper 105. The mounting blocks 13 are preferably made of high-strength metal to provide stable support. The interior of the mounting blocks 13 can be hollow, and the motor 531 can be installed inside the mounting blocks 13.

[0046] Furthermore, a positioning groove 109 can be provided at the lower end of the mounting groove 108. The positioning groove 109 is located on the side of the mounting groove 108 near the rear flap 107. When the mounting block 13 slides down along the positioning groove 109 and abuts against the bottom wall, it continues to slide horizontally and lock into the positioning groove 109, which can improve the stability of the mounting block 13. At the same time, a mounting plate 6 can be detachably installed in the positioning groove 109. The mounting plate 6 is inserted into the mounting groove 108. The mounting plate 6 can also be fixed to the unloading hopper by several locking bolts. Specifically, an opening for the locking bolts to pass through can be provided at the upper end of the unloading hopper 105, and a corresponding threaded hole is provided on the side wall of the mounting plate 6. After the locking bolt passes through the opening, it is threadedly connected to the threaded hole, thereby ensuring the stability of the positioning frame 1 during installation.

[0047] The implementation principle of the anti-collision auxiliary device for a ship unloader according to this application embodiment is as follows: When unloading through the grab bucket 104, if the grab bucket 104 shakes too much, it will hit the buffer plate 2 and drive the buffer plate 2 to continue moving towards the buffer cavity. At this time, the first spring 3 installed in the buffer cavity and the buffer pad 7 on the surface of the buffer plate 2 can simultaneously buffer and unload the grab bucket 104 to prevent the grab bucket 104 from directly hitting the rear flap 107 of the discharge hopper 105. When the grab bucket 104 moves to the limit position and begins to move in the opposite direction, the buffer plate 2 is blocked by the positioning block 41 and its movement is restricted. After the grab bucket 104 leaves the discharge hopper 105, the motor 531 is started, driving the connecting rod 52 to slide away from the buffer cavity, and the positioning block 41 is unlocked and reset.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
