Description

Technical Field

[0001] The present invention relates to the technical field of transport forklifts, in particular to a cargo anti-falling transport forklift. Background Art

[0002] Traditional forklifts rely heavily on overall forklift movement during cargo handling and pallet placement, a particularly significant issue when adjusting cargo position and center of gravity. Typically, when lifting cargo to a certain height or moving it to a target location, the forklift frequently needs to move forward, backward, or steer to precisely position the cargo. However, this approach not only requires highly skilled operators but also significantly restricts the forklift's overall movement in confined spaces or densely packed warehouses, leading to inefficient operations.

[0003] Furthermore, when placing or adjusting cargo on a traditional forklift, the friction between the cargo and the forklift surface is limited. This can cause the cargo to tilt, slide, or even fall over, especially when its center of gravity shifts, causing damage and potential safety hazards. This is particularly common during cargo transportation, loading and unloading, and warehousing operations. For heavier cargo, precise center of gravity control is difficult, resulting in poor stability and a high risk of handling.

[0004] Traditional forklifts typically rely on direct contact between the cargo and the forks to maintain stability. When moving or adjusting cargo, the lack of support and control at the bottom of the cargo causes the cargo to easily shift on the forks, making it difficult to maintain balance. This not only increases the risk of cargo falling during transport but also leads to inefficient cargo movement, failing to meet the requirements for efficient and safe cargo handling.

[0005] In response to the above-mentioned defects of the prior art, the present invention provides a cargo anti-slip transport forklift, which, through innovative design, achieves precise movement of cargo and adjustment of the center of gravity, improves stability during the transport process, avoids the excessive reliance of traditional forklifts on the overall movement of the forklift when adjusting the position of the cargo, and ensures the safety and efficiency of the cargo during the movement. Summary of the Invention

[0006] The present invention aims to solve one of the technical problems existing in the prior art or related technologies.

[0007] To this end, the technical solution adopted by the present invention is as follows: a cargo anti-slip handling forklift, comprising: a forklift frame, a synchronous guide group and a supporting assembly, wherein a first fork rod and a second fork rod are fixedly mounted on the surface of the forklift frame, a transmission box is fixedly mounted on the bottom surfaces of the first fork rod and the second fork rod, the number of the synchronous guide groups is several and evenly distributed on the surface of the transmission box, a first motor and a second motor are fixedly mounted on one end of the transmission box, the synchronous guide group comprises a guide box, a first worm and a second worm, both ends of the guide box are provided with a sliding sleeve groove, a bearing seat is rotatably sleeved on the surface of the first worm and the second worm, and the bearing seat is slidably sleeved on the surface of the sliding sleeve groove, and the ends of the first worm and the second worm on the surface of the several adjacent guide box surfaces are connected one by one by a universal coupling;

[0008] The transmission wheel is rotatably mounted on the surface of the wheel axle seat and a bevel gear disk is fixedly mounted on one side of the transmission wheel, and both ends of the transmission key shaft pass through the surface of the rotation support platform, and the two ends are respectively transmission-connected to the surfaces of the second worm gear and the bevel gear disk.

[0009] In a preferred example, the present invention can be further configured as follows: the first fork rod and the second fork rod have the same structure and are L-shaped, and the first fork rod and the second fork rod are arranged parallel to each other and fixedly mounted on the surface of the forklift frame.

[0010] In a preferred example, the present invention can be further configured as follows: the surfaces of the first fork rod and the second fork rod are provided with a plurality of through holes corresponding one-to-one to the guide boxes for ejecting the transmission wheel.

[0011] In a preferred example, the present invention can be further configured as follows: several adjacent first worms are synchronously connected through a universal coupling, and the first worm located at one end is connected to the output end of the first motor through a universal coupling; several adjacent second worms are synchronously connected through a universal coupling, and the second worm located at one end is connected to the output end of the second motor through a universal coupling.

[0012] Specifically, the first worm gear and the second worm gear are driven by the first motor and the second motor respectively, and the connection of multiple universal couplings is used to ensure that each supporting component maintains a connection effect during the lifting movement.

[0013] In a preferred example, the present invention can be further configured as follows: the sliding groove is arranged vertically to guide the first worm and the second worm to move up and down, the bottom surface of the hydraulic push rod is provided with a component fixedly connected to the bottom surface of the lifting top seat, and the component is made of flexible rubber material, and the bottom end thereof abuts against the bottom surface of the guide box inner cavity.

[0014] Specifically, under the telescopic drive control of the hydraulic jack, the lifting and lowering of the lifting jack seat as a whole and the lifting and lowering movement of the turntable are realized. The lifting and lowering of the turntable is realized under the insertion of the spline rod, and the synchronous rotation between the turntable and the first worm gear can be maintained. Under the drive of the hydraulic jack, the lifting jack seat and the turntable are lifted as a whole until the maximum lifting limit is reached. The turntable can also be lifted to a certain height under the guidance of the spline rod until the top surface of the transmission wheel determines the top surface of the first fork rod and the second fork rod for contacting the surface cargo.

[0015] In a preferred example, the present invention can be further configured as follows: a sleeve is provided on the inner side of the guide box and is sleeved on the surface of the first worm and the second worm, and the sleeve is slidably installed on the inner wall of the guide box to guide the lifting and sliding of the first worm and the second worm.

[0016] In a preferred example, the present invention can be further configured as follows: the surface of the transmission wheel is provided with an anti-slip layer, and the anti-slip layer is a flexible rubber material component to prevent the material from slipping when moving and achieve flexible contact with the material.

[0017] In a preferred example, the present invention can be further configured as follows: the ends of the first motor and the second motor are electrically connected to a control system, and the control system includes an independent drive control module and a synchronization control module. Under the independent drive of the first motor, the vertical axial rotation of the first worm gear and the turntable is realized, the direction of the transmission wheel is adjusted, and the direction of material movement is changed; under the joint drive of the first motor and the second motor, the rotation of the second worm gear is realized, and the rolling rotation of the transmission wheel on the surface of the wheel axle seat is realized through the transmission of the transmission key shaft and the bevel gear disk, and the lateral conveying of the material in the rolling direction of the transmission wheel is realized to adjust the center of gravity and moving position of the material.

[0018] The beneficial effects achieved by the present invention are:

[0019] 1. In the present invention, the first motor and the second motor drive the rotation of the transmission wheel to achieve precise movement and position adjustment of the goods, ensuring high stability of the materials during transportation and avoiding tilting or falling off. At the same time, the steering of the transfer platform and the rolling transmission of the transmission wheel can accurately adjust the position of the goods, so that the center of gravity of the goods can be adjusted to always maintain the best balance during transportation, avoiding the dumping of the goods due to unstable center of gravity.

[0020] 2. In the present invention, the lifting function of the hydraulic jack is used to ensure that during the position adjustment process, the goods can be pushed out by the transmission wheel and move smoothly, avoiding direct friction with the first fork rod and the second fork rod, thereby improving the safety of the movement of the goods. After the adjustment is completed, the transmission wheel will automatically descend and hide inside the first fork rod and the second fork rod, so that the goods are in direct contact with the fork rod, ensuring the stability of the goods during transportation.

[0021] 3. In the present invention, the rolling rotation function of the transmission wheel can realize efficient lateral movement of the goods on the surface of the first fork rod and the second fork rod, thereby simplifying the adjustment steps of the forklift during the transportation process, reducing the dependence on the overall movement of the forklift, and improving the efficiency of cargo position adjustment and loading and unloading.

DETAILED DESCRIPTION

[0032] To make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other without conflict.

[0033] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention.

[0034] A cargo-preventing forklift truck provided by some embodiments of the present invention will be described below with reference to the accompanying drawings.

[0035] Combine Figures 1-6 As shown in the figure, the present invention provides a cargo anti-drop forklift, which includes a forklift frame 100, a synchronous guide assembly 200, and a support assembly 300. The forklift frame 100 is the main supporting structure, and two parallel lifting structures, a first fork rod 110 and a second fork rod 120, are fixedly mounted on its surface to support the cargo to be transported.

[0036] The first and second fork rods 110, 120 are L-shaped, with a transverse support structure, a transmission box 130, fixedly connected to their bottom surfaces. This structure provides stability and support for the entire device. The arrangement of the transmission box 130 ensures that the cargo will not tilt or become unbalanced during the lifting process.

[0037] 2. Synchronous Guide Group Synchronous Guide Group 200 Structure and Working Principle

[0038] The synchronous guide assembly 200 is a key component responsible for adjusting the height and position of the cargo. It mainly includes a guide box 210, a first worm gear 220, and a second worm gear 230. The guide box 210 is a longitudinal guide rail structure with vertical sliding grooves 211 at both ends to guide the up and down movement of the first and second worm gears 220 and 230.

[0039] The first and second worm gears 220 and 230 are rotatably sleeved with bearing seats. The bearing seats are slidably mounted on the surface of the sliding sleeve groove 211, thereby ensuring stable vertical movement of the first and second worm gears 220 and 230. Adjacent first and second worm gears 220 and 230 are connected one by one via a universal coupling to achieve synchronous movement.

[0040] In particular, through the connection of the universal joint, it is ensured that the supporting components 300 inside each guide box 210 maintain synchronous drive during the lifting movement, and then the synchronous steering of the transfer platform 320 inside each guide box 210 and the synchronous rolling operation of the transmission wheel 330 are achieved through a single first motor 131 and a second motor 132, thereby avoiding the complexity of multiple controls and improving the operating efficiency of the equipment.

[0041] 3. Structure and Function of Support Assembly 300

[0042] The support assembly 300 is a key component for precisely moving and adjusting cargo in the present invention. It includes a lift base 310, a rotating support platform 320, a transmission wheel 330, a hydraulic jack 340, and a transmission key shaft 350. Specifically, the lift base 310 of the support assembly is fixedly mounted on the top of the guide box 210. Through its internal transmission mechanism, it directly contacts and adjusts the cargo.

[0043] A guide hole conduction rod 311 is provided on the surface of the lifting top seat 310, and a first worm gear 312 and a second worm gear 313 of a transmission device that are in transmission contact with the conduction rod 311 are provided inside the lifting top seat 310, which are respectively connected to the first worm 220 and the second worm 230, for transmitting vertical movement to the supporting assembly 300.

[0044] The hydraulic jack 340 of the jacking assembly is fixedly mounted on the bottom surface of the lifting base 310 and is connected at its top end to the rotating support 320 slidably mounted on the surface of the lifting base 310. During operation, the hydraulic jack 340 of the jacking assembly lifts the rotating support 320 to push the driving wheel 330 onto the surfaces of the first fork 110 and the second fork 120, so that it contacts the bottom of the cargo and adjusts its position.

[0045] After the position adjustment of the cargo is completed, the hydraulic push rod 340 will automatically retract, so that the transmission wheel 330 is hidden inside the first fork rod 110 and the second fork rod 120, so that the cargo is in direct contact with the surface of the first fork rod 110 and the second fork rod 120, ensuring the stability of the cargo during transportation and reducing unnecessary friction and the risk of tipping.

[0046] 4. Working principle of rolling and steering mechanism

[0047] In the present invention, the rolling and steering functions of the support assembly 300 are achieved through the coordination of multiple components. Specifically, the upper and lower surfaces of the rotating support 320 are respectively provided with a wheel axle seat 321 and a spline rod 322, which are used to fix the rolling device transmission wheel 330 and cooperate with the socket transmission member to achieve rolling and steering adjustment of the cargo.

[0048] The transmission wheel 330 can roll on the axle seat 321 through the rolling bearing installed on its surface to achieve the lateral movement of the goods. At the same time, the surface of the transmission wheel 330 is also provided with an anti-skid layer to ensure that the goods will not slide or shift during the rolling process.

[0049] When the first motor 131 is driven alone, the vertical axial rotation of the first worm gear 312 and the turntable 320 enables directional control of the transmission wheel 330, allowing the direction of cargo movement to be changed as needed. When the first and second motors 131 and 132 are driven jointly, the second worm gear 313 and the transmission key shaft 350 work together, guided by the bevel gear plate 331 of the transmission device, to ensure synchronous movement of the transmission wheel 330 during rolling. This allows cargo to move smoothly in the rolling direction of the transmission wheel 330, achieving efficient lateral transport.

[0050] Through this structural design, the present invention can accurately adjust the position and center of gravity of the cargo, ensuring that the cargo always maintains an optimal balance during the lifting and transportation process.

[0051] 5. Control system and operation process

[0052] The control system of the present invention includes an independent drive control module and a synchronization control module, which are responsible for the coordinated control of each component during the entire handling process. In actual operation, the control system can be driven by a single first motor 131 and a second motor 132 to achieve the synchronous steering and rolling of the supporting components inside each guide box 210.

[0053] The specific operation process is as follows:

[0054] Lifting and Jacking: Once the cargo is lifted off the ground by the first and second forks 110, 120, the hydraulic jack 340 of the jacking assembly is activated by the control system, lifting the transmission wheel 330 in the support assembly to the surface of the first and second forks 110, 120, and into contact with the bottom of the cargo. This allows the cargo's center of gravity to be further adjusted.

[0055] Direction and Position Adjustment: When the transmission wheel 330 contacts the bottom of the cargo, the control system, driven by the single first motor 131, vertically rotates the first worm gear 312 and the turntable 320, changing the cargo's direction of movement. Subsequently, the rolling surface of the transmission wheel 330 allows the cargo to move laterally across the first and second fork rods 110, 120.

[0056] Rolling and transmission control: When the first motor 131 and the second motor 132 are jointly driven, the transmission device of the transmission key shaft 350 and the bevel gear plate 331 is used to achieve synchronous movement of the transmission wheel 330 and the cargo during the rolling process, so that the cargo can move smoothly in the horizontal direction and complete the precise position adjustment of the cargo.

[0057] Positioning and Stable Transportation: After position adjustment is complete, the hydraulic jack 340 of the lifting assembly automatically descends, completely concealing the drive wheel 330 within the first and second fork rods 110, 120. This allows the cargo to directly contact the fork rod surfaces, ensuring stability during handling. At this point, the cargo is secure, preventing the risk of tilting or falling during transportation.
