Description

Technical Field

[0001] This invention relates to the field of cargo lifting technology, and more specifically, to a loading and unloading boom with full-stroke lateral shift function. Background Technology

[0002] In traditional hoisting operations, to meet the load-bearing and handling requirements of heavy goods such as glass, stone (e.g., granite, marble), and wood planks, large-tonnage forklifts, cranes, and extra-long booms are typically used. These devices require precise control of their position and angle when moving large, fragile items into containers to ensure safe and accurate placement. However, due to their large size and complex structure, large-tonnage forklifts are limited in operation within confined workshops or warehouses, making it difficult to flexibly adjust the handling position and angle. This often necessitates multiple adjustments, increasing the difficulty of operation, the risk of damage to goods, and the cost of loading fragile goods into containers. Therefore, providing a more flexible and efficient loading and unloading equipment is crucial to addressing these issues. Summary of the Invention

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please refer to Figure 1 The present invention provides a loading and unloading boom with full-stroke lateral shift function, including a frame beam 1, a sliding sleeve 2, a sliding rod 21, a moving trolley 3, a towing handle 31, a support frame 4 for supporting and fixing the top and bottom of the goods on both sides, a swing lateral shift mechanism 5 for connecting to a forklift and driving one end of the frame beam 1 to swing left and right and move laterally, and a lifting drive device 6 for driving the other end of the frame beam 1 to move up and down, etc. The components of this embodiment will be described in detail below with reference to the accompanying drawings.

[0028] like Figure 1 As shown, there are two sliding sleeves 2, which are slidably mounted on the frame beam 1 respectively. There are two sliding rods 21, which are slidably connected to the sliding sleeves 2 in a direction perpendicular to the frame beam 1 respectively. Each support frame 4 has a groove 40 on its outer side for engaging with the sliding rod 21. The frame beam 1 is installed in conjunction with the support frame 4 by engaging the sliding rod 21 with the groove 40. The swing lateral movement mechanism 5 is rotatably connected to one end of the frame beam 1. The moving trolley 3 is connected to the other end of the frame beam 1. The lifting drive device 6 is fixedly mounted on the moving trolley 3 facing upward. The output part of the lifting drive device 6 is connected to the other end of the frame beam 1 and can drive it to move up and down. The drag handle 31 is fixedly connected to the front end of the moving trolley 3.

[0029] like Figure 8As shown, this embodiment takes glass hoisting as an example. During implementation, the gantry beam 1 is used in conjunction with the sliding sleeve 2 and the sliding rod 21 to directly support the glass fixedly installed on the two support frames 4. The glass 101 can be made up of 15 pieces of glass with the same specifications with a total thickness. The dimensions of each piece of glass are 3660mm in length, 2440mm in height, and 10mm in thickness. Due to the large volume and heavy weight of the glass, the sliding sleeve 2 will not slide on its own when bearing the load. It has high overall strength and can provide stable support, positioning, and fixing functions, thus improving the safety of glass bearing. By pulling the drag handle 31, the entire boom of the mobile trolley 3 can be moved. The swing lateral movement mechanism 5 allows one end of the gantry beam 1 to swing left and right, increasing the flexible control of the glass and providing a larger operating range. The lifting drive device 6 is installed on the mobile trolley 3 and can drive the gantry beam 1 to move up and down, adapting to different height loading and unloading needs and helping to accurately load and unload containers.

[0030] like Figure 7 As shown, each support frame 4 may include a base plate 41, a lower protective cover 42, an upper protective cover 43, and rectangular tubes 44. The lower protective cover 42 and the upper protective cover 43 have a cross-section of []. Four rectangular tubes 44 are provided and connected in pairs parallel to each other between the inner walls of the lower protective cover 42 and the upper protective cover 43. The base plate 41 is fixedly connected to the bottom surface of the lower protective cover 42, and the support groove 40 is positioned downwards on the back of the upper protective cover 43. The lower protective cover 42 and the upper protective cover 43 can respectively fix and protect the bottom and top of the glass. The base plate 41 can provide support for the equipment, ensuring that the glass will not slip during handling. The rectangular tubes 44 enhance the overall load-bearing capacity and resistance to deformation, ensuring stability under heavy loads.

[0031] Specifically, the sliding sleeve 2 can be configured as a hollow square tube structure. The top of the sliding sleeve 2 is provided with a connecting hole seat 20 perpendicular to its opening direction. The sliding rod 21 is slidably connected in the connecting hole seat 20. The limiting pieces 211 at both ends of the sliding rod 21 can abut against the two ends of the outer wall of the connecting hole seat 20 when moving back and forth.

[0032] like Figure 2 As shown, the swing lateral movement mechanism 5 may include a lateral movement connecting seat 51 for forklift connection, a swing assembly 52 and a lateral movement drive device 53. The lateral movement drive device 53 is mounted on the front of the lateral movement connecting seat 51 along its length direction. The swing assembly 52 is connected to the output part of the lateral movement drive device 53 and is driven to move laterally by the lateral movement drive device 53. The top of the swing assembly 52 is hinged to one end of the frame beam 1.

[0033] like Figure 3As shown, the lateral movement drive device 53 may include a rack 530, a round rod 531, a sliding module 532, a spur gear 533, a gear drive device 534, and a reducer 5341. The cross-section of the lateral movement connecting seat 51 is inverted. The rack 530 is installed downward along the length direction of the lateral movement connecting seat 51 at the upper front end of the lateral movement connecting seat 51. Two round rods 531 are provided and are connected in parallel at intervals on both sides of the lateral movement connecting seat 51 and located below the rack 530. The sliding module 532 is slidably connected to the two round rods 531. The gear drive device 534 is installed inside the sliding module 532 through the reducer 5341. The spur gear 533 meshes with the teeth of the rack 530. The output part of the gear drive device 534 is connected to the spur gear 533 through the reducer 5341 through the back of the sliding module 532 and drives it to rotate, thereby driving the sliding module 532 to move back and forth along the length direction of the lateral movement connecting seat 51.

[0034] In this embodiment, the rack 530 meshes with the spur gear 533 through its teeth, converting the rotational motion of the spur gear 533 driven by the gear drive device 534 into the linear motion of the sliding module 532, while simultaneously driving the swing component 52 to move laterally, ensuring the accuracy and stability of the lateral movement.

[0035] Preferably, to further improve the smoothness of linear sliding of the sliding module 532 and prevent it from wobbling back and forth during sliding, the lateral drive device 53 may further include an L-shaped plate 5321, a first pulley 535, a second pulley 536, a third pulley 537, a guide rail 538, and a guide wheel 539. The top surface of the rack 530 is recessed with a guide groove 5301 along its length. The L-shaped plate 5321 is fixedly connected downwards to the top of the back of the sliding module 532 and extends outwards from the outside of the rack 530. The first pulley 535 is mounted downwards on the L-shaped plate 5321. The bottom surface of the horizontal section of the L-shaped plate 5321 rolls in contact with the guide groove 5301. The second pulley 536 is installed on the front of the vertical section of the L-shaped plate 5321 and rolls in contact with the upper back of the side-shifting connecting seat 51. The third pulley 537 is installed on the back of the sliding module 532 and rolls in contact with the lower front of the side-shifting connecting seat 51. The guide rail 538 is installed in the middle of the front of the side-shifting connecting seat 51 along the length direction of the side-shifting connecting seat 51. The guide wheel 539 is rotatably connected to the back of the sliding module 532 and rolls in contact with the top surface of the guide rail 538.

[0036] Furthermore, the swing assembly 52 may include a hinge seat 521, a connecting plate 522, a fixed column 523, a seamless tube 524, and a thrust bearing 525. The hinge seat 521 is hinged to one end of the frame beam 1. The bottom surface of the hinge seat 521 is fixedly mounted on the top surface of the connecting plate 522. The bottom surface of the connecting plate 522 is rotatably mounted on the fixed column 523 through the thrust bearing 525. The seamless tube 524 is fixedly sleeved on the outer wall of the fixed column 523. The fixed column 523 is fixedly connected to the front of the sliding module 532 through the seamless tube 524.

[0037] The swing assembly 52 is hinged to one end of the frame beam 1, so that one end of the frame beam 1 can swing up and down within a certain range when the lifting drive device 6 moves up and down. The thrust bearing 525 allows the connecting plate 522 to be rotatably mounted on the fixed column 523, thus enabling one end of the frame beam 1 to swing within a certain range and ensuring smooth rotation.

[0038] like Figure 4 and Figure 5 As shown, specifically, the swing lateral shifting mechanism 5 may further include a fixing block 54 for engaging with the upper end of the forklift mast and a connecting block 55 for detachably connecting with the lower end of the forklift mast. The fixing block 54 is provided in several pieces and is arranged downwards at intervals on the upper back of the lateral shifting connecting seat 51. Each fixing block 54 has a first slot 541 recessed on one side of its bottom. The connecting block 55 is provided in several pieces and is arranged upwards at intervals on the lower back of the lateral shifting connecting seat 51. Each connecting block 55 has a second slot 551 recessed on one side of its top. Each connecting block 55 has a mounting hole 552 penetrating its front and back sides.

[0039] In practice, the back of the side-shifting connector 51 can be detachably installed on the forklift via the forklift mast 102. When this embodiment needs to be installed on the forklift, the upper snap-fit ​​strip of the forklift mast 102 is snapped into the first snap-fit ​​groove 541, the second snap-fit ​​groove 551 of the connecting block 55 is snapped into the lower snap-fit ​​strip of the forklift mast 102, and finally the locking screws are inserted into each mounting hole 552 and fixedly connected to the side-shifting connector 51.

[0040] like Figure 6 and Figure 7As shown, the mobile trolley 3 may include electric fork wheels 32, fork arm fixing plate 33, trolley sleeve 34, crane rollers 341, first limiting block 342, and second limiting block 343. The trolley sleeve 34 is fitted onto the other end of the frame beam 1. Several crane rollers 341 are provided and are rotatably arranged opposite each other on the lower part of the inner wall surface of the trolley sleeve 34. The crane rollers 341 respectively roll in contact with the bottom surface of the frame beam 1. The first limiting block 342 and the second limiting block 343 are each provided in three pieces. The first limiting block 342 and the second limiting block 343 are respectively fixedly connected to the top surface and the side surfaces of the frame beam 1 at a distance from both ends of the trolley sleeve 34. The electric fork wheels 32 are installed on the bottom surface of the fork arm fixing plate 33. The lifting drive device 6 is fixedly installed facing upward on the top surface of the fork arm fixing plate 33. The output part of the lifting drive device 6 is connected to the bottom surface of the trolley sleeve 34 and can drive it to move up and down.

[0041] Preferably, the mobile trolley 3 may further include an inner trolley sleeve 344, an outer trolley sleeve 345, a controller 346, and a battery 347. The inner trolley sleeve 344 is fitted onto the outer side of the lifting drive device 6, with its top surface fixedly connected to the bottom surface of the trolley sleeve 34. The outer trolley sleeve 345 is fitted onto the outer side of the inner trolley sleeve 344, with its bottom surface fixedly connected to the fork arm fixing plate 33. The controller 346 and the battery 347 are respectively mounted on the fork arm fixing plate 33. The inner trolley sleeve 344 can protect the lifting drive device 6 from external interference, and the outer trolley sleeve 345 can protect its internal components, increasing the stability and integrity of the structure.

[0042] Furthermore, the lifting drive device 6 can preferably be configured as a hydraulic cylinder. The hydraulic cylinder can be connected to the oil pipe via a high-pressure oil pipe quick connector, allowing for quick disassembly. The hydraulic cylinder can provide a smooth and continuous power output, has a large lifting force, can precisely control the lifting and lowering movement of the glass, and the lifting process is smooth, reducing impact and vibration, and can maintain stable lifting and lowering action under different loads.

[0043] In specific implementation, the electric fork wheel 32 can provide strong traction for the mobile trolley 3, and the battery 347 and controller 346 ensure the power source and automated control of the entire mobile trolley 3, enabling the mobile trolley 3 to work independently without external power connection, improving the flexibility and convenience of the mobile trolley 3. The mobile trolley 3 can move axially along the gantry beam 1 through the trolley sleeve 34 and crane rollers 341. The first limit block 342 and the second limit block 343 are respectively left with a distance from the trolley sleeve 34. In order to avoid the collision between the trolley sleeve 34 and the first limit block 342 and the second limit block 343 when the swinging or lateral movement mechanism 5 swings or moves laterally, the risk of passive braking is reduced, and the trolley sleeve 34 can also be prevented from slipping when lifting or moving laterally.

[0044] In summary, this invention allows for convenient adjustment of the angle and position of goods and adapts to loading and unloading needs at different heights, providing a wider operating range and improving lifting coordination and continuity. Furthermore, this invention enables quick and easy overall assembly and disassembly without requiring secondary modifications to the forklift, making it flexible and convenient to use. Compared to traditional lifting equipment, it has a simple structure, strong load-bearing capacity, and is easy to handle and move, improving loading and unloading efficiency and operational flexibility, while also having low production costs.

[0045] It should be noted that, depending on actual needs, this invention is not only applicable to the hoisting of glass, but also to the hoisting of heavy goods such as stone (e.g., granite, marble), wood panels, alloy profiles, etc., except for glass mentioned in this embodiment.

[0046] The above embodiments are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present invention shall be considered equivalent substitutions and shall be included within the protection scope of the present invention.
