[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Please refer to Figure 1 An embodiment of the present invention provides a loading and unloading boom with a 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 supporting frame 4 for supporting and fixing the top and bottom of the goods on both sides, a swinging and lateral shifting 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.

During implementation, the frame beam 1 is used in conjunction with the sliding sleeve 2 and the sliding rod 21, which can directly support the glass fixedly mounted on the two supporting frames 4. The glass 101 can be composed of 15 pieces of glass of the same specification with a total thickness. The size of each piece of glass is 3660mm in length, 2440mm in height, and 10mm in thickness. Due to the large volume and heavy tonnage of the glass, the sliding sleeve 2 will not slide by itself when bearing the load. It has high overall strength and can provide stable support, positioning and fixing effects, thereby improving the safety of glass bearing. By pulling the drag handle 31, the entire boom of the mobile trolley 3 can be driven to move. The swinging side shifting mechanism 5 enables one end of the frame beam 1 to swing left and right, thereby 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, which can drive the frame beam 1 to move up and down to adapt to the loading and unloading requirements of different heights, and is conducive to accurate loading and unloading of cabinets.

The cross section of the side shift connecting seat 51 is arranged in an inverted [] shape. The rack 530 is installed downward on the front upper end of the side shift connecting seat 51 along the length direction of the side shift connecting seat 51. Two round rods 531 are provided and are respectively connected to the two sides of the side shift connecting seat 51 in parallel and spaced apart and are located below the rack 530. The sliding module 532 is slidably connected to the two round rods 531. The gear driving device 534 is installed inside the sliding module 532 through the reducer 5341. The spur gear 533 is meshed with the tooth position of the rack 530. The output part of the gear driving device 534 passes through the back side of the sliding module 532 through the reducer 5341 and is transmission-connected to the spur gear 533 and drives it to rotate, thereby driving the sliding module 532 to move back and forth along the length direction of the side shift connecting seat 51.

[0034] When this embodiment is implemented, the rack 530 meshes with the spur gear 533 through the tooth position, converting the rotational motion of the spur gear 533 driven by the gear driving device 534 into the linear motion of the sliding module 532, while driving the swing assembly 52 to move sideways, ensuring the accuracy and stability of the lateral movement.

[0035] Preferably, in order to further improve the smoothness of the linear sliding of the sliding module 532 and prevent it from shaking back and forth when sliding, the side shift driving device 53 may also 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 concavely provided with a guide groove 5301 along its length direction. The L-shaped plate 5321 is fixedly connected downwardly to the top of the back of the sliding module 532 and extends out of the outer side of the rack 530. The first pulley 535 is installed downwardly on the L-shaped plate 5321. The bottom surface of the horizontal section of the L-shaped plate 5321 is in rolling 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 is in rolling contact with the upper back side of the side shift connecting seat 51, the third pulley 537 is installed on the back side of the sliding module 532 and is in rolling contact with the lower front side of the side shift connecting seat 51, the guide rail 538 is installed in the middle of the front side of the side shift connecting seat 51 along the length direction of the side shift connecting seat 51, and the guide wheel 539 is rotatably connected to the back side of the sliding module 532 and is in rolling contact with the top surface of the guide rail 538.

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

[0037] Among them, the swing component 52 is hinged to one end of the frame beam 1, so that when the lifting drive device 6 moves up and down, one end of the frame beam 1 can swing up and down within a certain range, and the thrust bearing 525 enables the connecting plate 522 to be rotatably set on the fixed column 523, so that one end of the frame beam 1 can swing within a certain range, ensuring the smoothness of rotation.

[0038] like Figure 4 and Figure 5 As shown, specifically, the swing side-shift mechanism 5 can also include a fixed block 54 for clamping 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 fixed block 54 is provided with a plurality of blocks and are arranged at intervals downward on the upper back side of the side-shift connecting seat 51. A first clamping groove 541 is recessed on one side of the bottom of each fixed block 54. The connecting block 55 is provided with a plurality of blocks and are arranged at intervals upward on the lower back side of the side-shift connecting seat 51. A second clamping groove 551 is recessed on one side of the top of each connecting block 55. Each connecting block 55 has a mounting hole 552 that runs through the front and back sides thereof.

[0039] During specific implementation, the back of the side-shift connecting seat 51 can be detachably installed on the forklift through the forklift mast 102. When the present embodiment needs to be installed on the forklift, the upper clamping strip of the forklift mast 102 is clamped with the first clamping groove 541, and then the second clamping groove 551 of the connecting block 55 is clamped with the lower clamping strip of the forklift mast 102. Finally, a locking screw is inserted into each mounting hole 552 and fixedly connected to the side-shift connecting seat 51.

[0040] like Figure 6 and Figure 7As shown, the mobile trolley 3 may include an electric fork wheel 32, a fork arm fixing plate 33, a trolley sleeve 34, a crane roller 341, a first limit block 342, and a second limit block 343.

[0041] Preferably, the mobile trolley 3 may further include a trolley inner sleeve 344, a trolley outer sleeve 345, a controller 346 and a power supply battery 347. The trolley inner sleeve 344 is sleeved on the outer side of the lifting drive device 6 and its top surface is fixedly connected to the bottom surface of the trolley sleeve 34.

The controller 346 and the power supply battery 347 are respectively installed on the fork arm fixing plate 33. The trolley inner sleeve 344 can protect the lifting drive device 6 from external interference, and the trolley outer sleeve 345 can protect its internal components, thereby increasing the stability and integrity of the structure.

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

[0043] During specific implementation, the electric fork wheel 32 can provide strong traction for the mobile trolley 3, and the battery 347 and the controller 346 ensure the power source and automatic control of the entire mobile trolley 3, so that the mobile trolley 3 can work independently without an external power supply connection, thereby improving the flexibility and convenience of the mobile trolley 3. The mobile trolley 3 can move axially along the frame beam 1 through the trolley sleeve 34 and the crane roller 341. The first limit block 342 and the second limit block 343 are respectively separated from the trolley sleeve 34 by one end distance. 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 and lateral shifting mechanism 5 swings or shifts sideways, the risk of passive braking is reduced, and the trolley sleeve 34 can be prevented from slipping during lifting or lateral movement.

In addition, the present invention can achieve fast and convenient overall disassembly and assembly without the need for secondary modification of the forklift, and is flexible and convenient to use. Compared with traditional lifting equipment, it has a simple structure, strong bearing capacity, and is convenient to carry and move, which improves loading and unloading efficiency and operational flexibility, and has low production costs.
