Description

Technical Field

[0001] This invention relates to the field of industrial material handling equipment technology, and more specifically to a shock-absorbing forklift for transporting goods. Background Technology

[0002] In modern logistics and industrial production, shock-absorbing forklifts are among the most commonly used machines for handling goods in the logistics industry. As an indispensable handling tool, forklifts undertake the task of transferring goods between different stages. The operator inserts the forks of the shock-absorbing forklift into the pallet's slots and transfers the goods by adjusting the height of the forks. During goods transportation, traditional forklift shock absorbers exhibit significant vibrations when handling goods. Due to the lack of an effective shock absorption mechanism, goods are easily shaken off, leading to damage and causing breakage or detachment at the forklift's joints, rendering the forks unable to properly support the goods. Furthermore, when traveling on uneven roads, over speed bumps, or during loading and unloading operations, the impact force is directly transmitted to the goods, causing damage. Therefore, this solution provides a new shock-absorbing forklift for transporting goods. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the present invention provides a shock-absorbing forklift, which has the advantage of absorbing impact force by setting shock-absorbing wheel sets, effectively preventing the impact force from being transmitted to the goods, and greatly reducing the damage to the goods caused by bumps.

[0004] The technical solution adopted by this invention to solve its technical problem is:

[0005] A shock-absorbing forklift includes a frame with a fixed mast. Two shock-absorbing wheel sets are symmetrically mounted on the left side of the frame, and two auxiliary wheels are symmetrically rotatably connected to the right side of the frame. Two vertical slots are symmetrically opened on the inner side of the mast, and a T-block is slidably connected between the two vertical slots. A motor I is fixedly mounted on the frame, and a lead screw I is connected to the output shaft of the motor I. The lead screw I is threadedly connected to the T-block. A frame is fixedly mounted on the T-block, and a crossbeam is mounted on the frame. Two adjustable fork arms are symmetrically mounted on the crossbeam.

[0006] Two symmetrical sliding grooves are provided on the frame, and clamping components are slidably connected in both sliding grooves. Electric push rods I are fixed between the two clamping components and the frame.

[0007] The clamping component includes a side frame slidably connected in a groove. One end of the side frame is fixed to the telescopic end of the electric push rod I. Two C-shaped frames are symmetrically fixed to the other end of the side frame. A disc is rotatably connected between the two C-shaped frames. A motor IV is fixed to the side frame. The disc is fixed to the output shaft of the motor IV. A cross is fixed to the disc. A turntable is fixed inside the cross.

[0008] Electric push rods II are fixedly connected to all four ends of the cross. Each electric push rod II has a folding rod fixedly connected to its telescopic end. Each folding rod has an angle plate fixedly connected to the inner side of the turntable. Attached Figure Description

Detailed Implementation

[0025] like Figures 1 to 6 As shown:

[0026] A shock-absorbing forklift includes a frame 101 fixedly connected to a mast 105. Two shock-absorbing wheel sets are symmetrically mounted on the left side of the frame 101, and two auxiliary wheels 111 are symmetrically rotatably connected to the right side of the frame 101. Two vertical slots 106 are symmetrically opened on the inner side of the mast 105, and a T-block 303 is slidably connected between the two vertical slots 106. A motor I 107 is fixedly connected to the frame 101. A lead screw I 108 is connected to the output shaft of the motor I 107 through a coupling. The lead screw I 108 is threadedly connected to the T-block 303. A frame 301 is fixedly connected to the T-block 303. A crossbeam 201 is mounted on the frame 301. Two adjustable fork arms 205 are symmetrically mounted on the crossbeam 201.

[0027] Two handles 110 are symmetrically fixed to the middle of the gantry frame 105.

[0028] A handle 109 is fixedly connected to the upper end of the gantry frame 105.

[0029] The control motor I107 starts, driving the lead screw I108 to rotate. The lead screw I108 drives the two forks 205 on the frame 301 and crossbeam 201 to move downwards. Holding the two handles 110, push the forklift to move as a whole. The two forks 205 are inserted under the pallet. Then, the control motor I107 starts in reverse, driving the lead screw I108 to move the two forks 205 on the frame 301 and crossbeam 201 upwards to lift the goods. Then, holding the two handles 110, push the forklift to the designated position. When the forklift passes over uneven ground, a vertical impact force will be generated between the goods and the forks 205. The two shock-absorbing wheel sets can absorb the impact force and prevent the impact force from being transmitted to the goods, reducing the damage to the goods caused by bumps.

[0030] When the auxiliary wheels 111 pass over speed bumps or uneven surfaces, the handle 110 can be pulled to tilt the frame 101 around the two shock-absorbing wheel sets. The two auxiliary wheels 111 are raised and maintained in this state to propel the forklift. This prevents the vibration generated when the auxiliary wheels 111 pass over speed bumps from being transmitted to the goods. In this way, only the two shock-absorbing wheel sets absorb the impact force through the speed bump, and the handle 109 can assist in gripping, further improving the stability of operating the forklift. Alternatively, the auxiliary wheels 111 can also be swivel casters with shock absorption.

[0031] like Figure 5 As shown:

[0032] The crossbeam 201 is fixedly connected to a dovetail rail 202 and a motor II 203. Both fork arms 205 are slidably connected to the dovetail rail 202. The output shaft of the motor II 203 is connected to one end of a bidirectional screw 204 through a coupling. The other end of the bidirectional screw 204 is rotatably connected to the crossbeam 201. The two fork arms 205 are respectively threaded to both ends of the bidirectional screw 204.

[0033] When the motor II 203 starts, it drives the bidirectional screw 204 to rotate. The dovetail rail 202 and the fork arm 205 cooperate to guide and limit the fork arm 205. The bidirectional screw 204 drives the two fork arms 205 to move closer or further apart, changing the distance between the two fork arms 205, thus making it suitable for pallets of different widths or for lifting goods of different lengths.

[0034] like Figures 7 to 12 As shown:

[0035] Two symmetrical sliding grooves 302 are provided on the frame 301. Clamping components are slidably connected in both sliding grooves 302. Electric push rods I 304 are fixedly connected between the two clamping components and the frame 301.

[0036] The clamping component includes a side frame 401 slidably connected in the slide groove 302. One end of the side frame 401 is fixed to the telescopic end of the electric push rod I 304, and the other end of the side frame 401 is symmetrically fixed to two C-shaped frames 402. A disc 404 is rotatably connected between the two C-shaped frames 402. A motor IV 403 is fixed to the side frame 401. The disc 404 is fixed to the output shaft of the motor IV 403. A cross 405 is fixed to the disc 404, and a turntable 406 is fixed inside the cross 405.

[0037] After the two fork arms 205 lift the goods, the telescopic ends of the two electric push rods I 304 are retracted, which drives the two side frames 401 to move closer to each other. The two side frames 401 drive the two turntables 406 to move closer to the goods on the fork arms 205 until the two turntables 406 are respectively attached to the two sides of the goods, limiting the two sides of the goods to prevent the goods from falling from the side during the movement of the forklift, or from moving left and right due to uneven road surface.

[0038] The cross 405 is fixedly connected to four ends of an electric push rod II 407. Each electric push rod II 407 is fixedly connected to a folding rod 408 at its telescopic end. Each folding rod 408 is fixedly connected to a corner plate 409 that fits against the inner side of the turntable 406.

[0039] When the two turntables 406 are respectively attached to both sides of the goods, the telescopic ends of the four electric push rods II 407 at the bottom are retracted, driving the four folding rods 408 at the bottom to move upward until the four corner plates 409 at the bottom move upward to lift the goods and form a certain gap between them and the fork arms 205, leaving space for the goods to flip. Then, the telescopic ends of the four electric push rods II 407 at the top are also retracted, and the four folding rods 408 at the top drive the four corner plates 409 at the top to move downward until they contact and abut against the goods. The multiple corner plates 409 on both sides work together to further lift the goods on the two fork arms 205 from both sides. Then, the motors IV 403 on both sides are started to drive the two discs 404 to rotate. The two discs 404 rotate synchronously through the cross 405, the turntable 406 and the multiple corner plates 409 holding the goods, thereby realizing the flipping of the goods.

[0040] With the rapid development of modern logistics and manufacturing, the types of goods are becoming increasingly diversified. Many large, heavy, and uniquely shaped goods, such as stacked packages, require not only relocation during handling but also flipping to meet processing, loading, or storage requirements. Traditional forklifts lack flipping capabilities, necessitating manual assistance or additional equipment to complete such operations, leading to complex handling processes, reduced efficiency, and increased costs. The forklift described in this application, however, can not only transport goods but also flip them over for larger items that are difficult to handle manually.

[0041] After the flipping is completed, the extension ends of the four electric push rods II 407 at the lower end are extended to drive the corner plate 409 at the lower end to move downward until the goods fall back onto the two fork arms 205, thus completing the flipping operation of the goods.

[0042] Furthermore, the corner plates 409 on both clamping members are provided with four in the circumferential direction, so they can make multi-point contact and clamp and fix with the goods, thereby enabling the flipping operation of goods of different shapes and meeting the flipping needs of diverse goods.

[0043] Furthermore, such as Figure 13As shown, the width of the angle plate 409 can be set to extend beyond the inner side of the folding bar 408. This increases the width of the angle plate 409, increasing the contact surface with the goods and making the clamping more stable. Secondly, the portion extending beyond the folding bar 408 forms a raised edge, which can be inserted into the cylinder to limit the cylindrical goods, preventing the cylinder from rolling off the fork arm 205 during forklift transport. Specifically, after the two fork arms 205 scoop up the cylinder, the multiple angle plates 409 on the turntable 406 are moved inwards and converge. Then, the two turntables 406 are moved closer together to fit against the sides of the cylinder. Finally, the multiple angle plates 409 are moved away from each other until they abut against the inner wall of the cylinder. Figure 14 As shown, this method limits the movement of the cylinder, preventing it from rolling freely during transportation or when it is bumpy.

[0044] like Figures 6 to 7 As shown:

[0045] Guide rods 305 and motor III 306 are fixedly connected to both ends of the frame 301 respectively. The output shaft of motor III 306 is connected to lead screw II 307 through a coupling. One end of the crossbeam 201 is slidably connected to the guide rod 305, and the other end of the crossbeam 201 is threadedly connected to lead screw II 307.

[0046] Furthermore, the motor Ⅲ306 can be controlled to start and drive the lead screw Ⅱ307 to rotate. The lead screw Ⅱ307 drives the two forks 205 on the crossbeam 201 to move upward, placing the goods between the frame 101 and the two forks 205. Then, the two turntables 406 are brought closer together to clamp the left and right sides of the goods, limiting the left and right sides of the goods and preventing the goods from moving left and right when the forklift passes over uneven surfaces. Then, the motor Ⅲ306 is controlled to drive the two forks 205 to move downward and press against the top of the goods, thereby limiting the goods from the top and preventing the goods from moving up and down when the forklift passes over uneven surfaces.

[0047] like Figures 3 to 4 As shown:

[0048] The shock-absorbing wheel set includes a groove frame 102 fixed to the frame 101, a wheel frame 103 slidably connected in the groove frame 102, and a roller rotatably connected in the wheel frame 103.

[0049] Multiple shock-absorbing springs 104 are fixed between the slot frame 102 and the wheel frame 103. The multiple shock-absorbing springs 104 are used to absorb the vibration when the forklift passes over uneven road surfaces, playing a role in buffering and shock absorption, thereby enabling the forklift to pass over uneven road surfaces smoothly.

[0050] Furthermore, the shock-absorbing wheel set can also be directly fixed to the frame 101 using existing omnidirectional shock-absorbing casters, which can also activate the shock absorption function.
