Technical Field
[0001] This utility model belongs to the field of ship loader technology, and specifically relates to a self-vertical support for the boom of a ship loader. Background Technology
[0002] In large port machinery such as ship loaders and gantry cranes, to achieve accurate signal reception of the GNSS positioning system, a "weighted pendulum self-vertical support" is needed to ensure that the antenna is always perpendicular to the ground. The core structure of this support consists of a U-shaped plate, a hollow rotating shaft, an annular block (counterweight carrier), a ball joint, and an antenna mount. The ball joint, as a key connecting component, connects the annular block and the antenna mount. It must allow the antenna mount to flexibly adjust its angle with the weighted pendulum arm, while also ensuring structural stability under harsh conditions such as salt spray, rain, and strong vibration. As the operating efficiency of port machinery increases, the frequency of antenna maintenance (such as signal calibration and component replacement) has increased significantly. The ease of installation and disassembly between the antenna mount and the ball joint has gradually become a key factor affecting the efficiency of equipment operation and maintenance.
[0003] In current gravity pendulum self-vertical supports, the connection between the antenna mount and the ball joint is mostly fixed by bolts or welded. The bolt fixing method requires multiple sets of bolts to lock the antenna mount flange to the mounting seat on the ball joint. Tools such as wrenches are required during disassembly and assembly. In the high humidity and salt spray environment of the port, the bolts are prone to rust and jamming. Each maintenance takes a long time, and repeated disassembly can easily lead to stripped threads, affecting the reliability of the structure. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a self-vertical support for ship loader booms.
[0005] To achieve the above objectives, this utility model provides a self-vertical support for a ship loader boom, comprising a boom body, a U-shaped plate connected to the upper end of the boom body, a rotating rod connected to the upper part of one side of the U-shaped plate, one end of the rotating rod extending through to one side of the U-shaped plate, a connecting ring connected to the middle of the outer wall of the rotating rod, a connecting rod connected to the middle of the lower end of the connecting ring, a counterweight connected to the lower end of the connecting rod, a support block connected to the middle of the upper end of the connecting ring, a mounting plate connected to the upper end of the support block, a ball joint connected to the upper end of the mounting plate, a quick-release mechanism connected to the upper end of the ball joint, and an antenna mount connected to the upper end of the quick-release mechanism.
[0006] In the above technical solution, further, both ends of the rotating rod are connected to rotating blocks, the two rotating blocks are respectively located on both sides of the U-shaped plate, one side of the two rotating blocks is connected to a damper, and the lower ends of the two dampers are rotatably connected to both sides of the U-shaped plate.
[0007] In the above technical solution, the quick-release mechanism further includes a mounting base, an mounting groove is provided in the middle of the upper end of the mounting base, a fixing block is connected to the lower end of the inner wall of the mounting groove, and a connecting groove is provided in the middle of the upper end of the fixing block.
[0008] In the above technical solution, the cross-sectional shape of the connecting groove is convex, and a buffer spring is circumferentially connected to the lower end of the inner wall of the connecting groove. A pressing block is connected to the upper end of the buffer spring. The cross-sectional shape of the pressing block is convex. The pressing block is located inside the connecting groove. A stabilizing groove is opened inside the fixing block corresponding to both sides of the connecting groove. A stabilizing block is connected to both sides of the pressing block corresponding to the two stabilizing grooves. The stabilizing block slides inside the stabilizing groove.
[0009] In the above technical solution, the upper end of the extrusion block is connected to a mounting plate, and the lower end of the mounting plate is circumferentially connected to three sets of insert rods. The upper end of the mounting base is provided with a sliding groove corresponding to the three insert rods. The sliding groove is L-shaped, and the three insert rods are respectively located inside the three sliding grooves.
[0010] In the above technical solution, a connecting block is further connected to the lower part of one side of each of the three plug rods, and a plug is connected to the middle of the upper end of each of the three connecting blocks. The three plugs are located below the mounting base. Slots are provided at the lower end of the mounting base corresponding to the multiple plugs. The shape of the plugs is adapted to the shape of the slots. The three plugs are respectively inserted into the three slots.
[0011] In the above technical solution, further, buffer blocks are connected to both sides of the inner wall of the U-shaped plate, and the two buffer blocks are sleeved on both sides of the outer wall of the rotating rod. The buffer blocks are made of rubber.
[0012] Compared with the prior art, the present invention has the following beneficial effects: This device, through a U-shaped plate, rotating rod, connecting ring, and counterweight, uses gravity to keep the support block, mounting plate, and upper ball joint and antenna mount perpendicular to the ground, effectively compensating for attitude deviations caused by pitch and vibration of the port machinery boom. At the same time, the dampers on both sides of the rotating rod apply damping force through the rotating block, which can slow down the swing speed of the rotating rod and prevent the antenna from affecting signal reception due to violent shaking. The rubber buffer block on the inner wall of the U-shaped plate can provide elastic buffer when the rotating rod rotates to the limit position, preventing rigid collisions between components and significantly improving the service life and operational stability of the overall structure under harsh working conditions such as salt spray and strong vibration. The quick-release mechanism, through the cooperation of the mounting base and mounting plate, guides the insertion rod with an L-shaped sliding groove to complete the insertion, rotation, and locking actions. Combined with the elastic force of the buffer spring, the insertion block and slot are precisely connected. The entire process can achieve rapid assembly and disassembly of the antenna mount without tools. Compared with the traditional bolt fixing method, it shortens the maintenance time per operation and effectively reduces the operational intensity of maintenance personnel. Moreover, the stabilizing blocks on both sides of the compression block cooperate with the stabilizing groove to prevent the mounting plate from shifting and ensure the positioning accuracy of the antenna mount after each assembly and disassembly. At the same time, the convex structure of the connecting groove and the compression block can prevent the components from loosening, further ensuring the reliability of the quick-release structure and adapting to the actual needs of high-frequency maintenance of port machinery.

[0015] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0016] like Figures 1-7 The image shows a self-vertical support for a ship loader boom.
[0017] The system includes a boom body 1, with a U-shaped plate 2 connected to the upper end of the boom body 1. A rotating rod 3 is connected to the upper part of one side of the U-shaped plate 2. One end of the rotating rod 3 extends through to one side of the U-shaped plate 2. A connecting ring 6 is connected to the middle of the outer wall of the rotating rod 3. A connecting rod 7 is connected to the middle of the lower end of the connecting ring 6. A counterweight 8 is connected to the lower end of the connecting rod 7. A support block 9 is connected to the middle of the upper end of the connecting ring 6. A mounting plate 10 is connected to the upper end of the support block 9. A ball joint 11 is connected to the upper end of the mounting plate 10. A quick-release mechanism is connected to the upper end of the ball joint 11. An antenna mount 24 is connected to the upper end of the quick-release mechanism. Rotating blocks 4 are connected to both ends of the rotating rod 3. The two rotating blocks 4 are located on both sides of the U-shaped plate 2. A damper 5 is connected to one side of the two rotating blocks 4. The lower ends of the two dampers 5 are rotatably connected to both sides of the U-shaped plate 2. Buffer blocks 25 are connected to both sides of the inner wall of the U-shaped plate 2. The two buffer blocks 25 are sleeved on both sides of the outer wall of the rotating rod 3. The buffer blocks 25 are made of rubber. The boom body 1 provides the installation foundation for the overall structure and moves synchronously with the port machinery's operation. The U-shaped plate 2 supports the boom 3 and related components, providing stable rotational support for the boom 3. The boom 3 rotates around its own axis, driving the connecting ring 6 and the upper structure to achieve adaptive angle adjustment. The rotating block 4 connects the boom 3 to the damper 5, transmitting damping force to regulate the boom 3's rotation state. The damper 5 applies resistance to the boom 3's rotation, slowing its swing speed and preventing severe shaking caused by boom vibration. The connecting ring 6 fixes the connecting rod 7 to the support block 9, enabling force transmission between the counterweight block 8 and the upper structure. The connecting rod 7 suspends the counterweight block 8 and... To ensure the stability of its vertically hanging state, the counterweight 8 is used to generate a constant torque using gravity, so that the connecting ring 6 and the upper structure always maintain a vertical orientation to the ground. The support block 9 is used to raise the height of the mounting plate 10 to avoid interference with the lower structure. The mounting plate 10 is used to fix the ball joint 11 and provide it with a horizontal installation reference. The ball joint 11 is used to enable the antenna mount 24 to rotate flexibly at multiple angles, compensating for attitude deviations caused by installation errors and operating vibrations. The buffer block 25 is used to provide elastic buffer when the rotating rod 3 rotates to its limit position, preventing the rotating rod 3 from having a rigid collision with the U-shaped plate 2. The antenna mount 24 is used to install and fix the GNSS antenna, ensuring the stable bearing of the antenna.
[0018] The quick-release mechanism includes a mounting base 12, with a mounting groove 13 in the middle of its upper end. A fixing block 14 is connected to the lower end of the inner wall of the mounting groove 13. A connecting groove 15 is formed in the middle of the upper end of the fixing block 14. The connecting groove 15 has a convex cross-sectional shape. Buffer springs 16 are circumferentially connected to the lower end of the inner wall of the connecting groove 15. A pressing block 17 is connected to the upper end of the buffer springs 16. The pressing block 17 has a convex cross-sectional shape and is located inside the connecting groove 15. Stabilizing grooves are formed inside the fixing block 14 corresponding to both sides of the connecting groove 15. Stabilizing blocks are connected to both sides of the pressing block 17 corresponding to the two stabilizing grooves. The stabilizing blocks slide inside the stabilizing grooves. The upper end of the pressure block 17 is connected to the mounting plate 18, and the lower end of the mounting plate 18 is circumferentially connected to the insertion rods 19. There are three sets of insertion rods 19. The upper end of the mounting base 12 is provided with a sliding groove 20 corresponding to the three insertion rods 19. The sliding groove 20 is L-shaped. The three insertion rods 19 are located inside the three sliding grooves 20 respectively. The lower part of one side of the three insertion rods 19 is connected to the connecting block 21. The middle part of the upper end of the three connecting blocks 21 is connected to the insertion block 22. The three insertion blocks 22 are located below the mounting base 12. The lower end of the mounting base 12 is provided with slots 23 corresponding to the multiple insertion blocks 22. The shape of the insertion block 22 is adapted to the shape of the slot 23. The three insertion blocks 22 are respectively inserted into the three slots 23. Mounting base 12 is used to connect ball joint 11 to other components of quick-release mechanism, providing a mounting carrier. Mounting groove 13 is used to accommodate the lower structure of fixing block 14 and pressing block 17, realizing a concealed layout of components. Fixing block 14 is used to fix buffer spring 16 and provide a machining basis for connecting groove 15 and stabilizing groove. Connecting groove 15 is used to provide space for pressing block 17 to move up and down, and restricts the movement trajectory of pressing block 17 through convex structure. Buffer spring 16 is used to generate restoring force through elastic deformation, pushing pressing block 17 and upper structure to achieve locking and separation. Pressing block 17 is used to transmit the elastic force of buffer spring 16, driving mounting plate 18 to achieve up and down movement and locking. The stabilizing groove and stabilizing block work together to limit the movement direction of the pressing block 17, preventing it from shifting or rotating during movement. The mounting plate 18 is used to connect the antenna base 24 and the insertion rod 19, serving as the direct load-bearing component of the antenna base 24. The insertion rod 19 is used to slide along the slide groove 20 to achieve the positioning and rotation guidance of the mounting plate 18. The slide groove 20 is used to guide the insertion rod 19 to complete the insertion, rotation, and locking action process through the L-shaped structure. The connecting block 21 is used to connect the insertion rod 19 and the insertion block 22 to achieve the transmission of force and motion. The insertion block 22 works with the slot 23 to achieve the mechanical locking of the mounting plate 18 and the mounting base 12 through insertion, preventing the antenna base 24 from accidentally falling off.
[0019] Working principle: When the device is running, the boom body 1 serves as the basic load-bearing structure, driving the U-shaped plate 2 to move synchronously with the operation of the port machinery. The rotating rod 3 is connected to the U-shaped plate 2 through the rotating blocks 4 at both ends, and can rotate freely around its own axis. When the boom pitches or swings, the connecting ring 6 rotates synchronously with the rotating rod 3. The counterweight 8 suspended at its lower end through the connecting rod 7 always remains in a drooping state under the action of gravity. Then, the connecting ring 6 drives the rotating rod 3 to adaptively adjust the angle, so that the support block 9, the mounting plate 10, the ball joint 11 above, and the antenna mount 24 always maintain a vertical attitude to the ground, realizing the self-vertical function of the antenna.
[0020] During the rotation of the boom 3, the dampers 5 on both sides apply damping force to it through the rotating block 4, which slows down the swing speed of the boom 3 and avoids violent shaking caused by boom vibration; the rubber buffer block 25 on the inner wall of the U-shaped plate 2 provides elastic buffer when the boom 3 rotates to the limit position, preventing the boom 3 from having a rigid collision with the U-shaped plate 2 and protecting the structural integrity.
[0021] During the operation of the quick-release mechanism, when installing the antenna mount 24, first align the three sets of insert rods 19 at the lower end of the mounting plate 18 with the vertical section of the L-shaped slide groove 20 of the mounting base 12, and press the mounting plate 18 down. At this time, the pressing block 17 is pressed and moves downward along the connecting groove 15, simultaneously compressing the buffer spring 16. The stabilizing blocks on both sides of the pressing block 17 slide vertically along the stabilizing groove of the fixing block 14 to ensure smooth movement. As the mounting plate 18 moves down, the insert rods 19 drive the connecting block 21 and the insert block 22 to move downward synchronously until the insert block 22 is lower than the lower end face of the mounting base 12. While maintaining the downward pressing state, rotate the mounting plate 18 so that the insert rods 19 slide along the arc section of the slide groove 20, driving the insert block 22 to rotate synchronously to directly below the slot 23. At this time, release the mounting plate 18, the buffer spring 16 releases its elastic force to push the pressing block 17 upward to reset, driving the insert block 22 to accurately insert into the slot 23, completing the locking and fixing of the antenna mount 24. During disassembly, press down on the mounting plate 18 to disengage the insert 22 from the slot 23, rotate it in the opposite direction to release it, and then lift the mounting plate 18 upwards under the action of the spring force to achieve quick separation of the antenna mount 24.
