Description

Technical Field

[0001] This utility model relates to the field of logistics forklift technology, and in particular to a logistics forklift with anti-tipping function. Background Technology

[0002] Forklifts are industrial material handling vehicles, referring to various wheeled handling vehicles used for loading, unloading, stacking, and short-distance transport of palletized goods. They are commonly used for transporting large items in warehouses and are typically powered by internal combustion engines or batteries. The use of forklifts can greatly improve the efficiency of logistics handling and better meet the needs of logistics transportation.

[0003] When using a logistics forklift, the forks are used to lift the goods off the ground before transferring them. However, when lifting goods, the forklift's center of gravity shifts with the weight of the goods. When the goods are heavy, the forklift may tilt forward, causing the rear of the forklift to lift up. This can easily lead to the goods coming off the forks, as well as injuries to personnel and damage to the forklift, seriously affecting the safety of logistics transportation. Utility Model Content

[0004] The purpose of this application is to provide a logistics forklift with anti-tipping function to solve the problem mentioned in the background art that when using a logistics forklift to lift goods, the center of gravity of the logistics forklift will shift with the weight of the goods. When the weight of the goods is large, the logistics forklift will tilt forward when lifting the goods, causing the rear of the forklift to lift up. This not only easily causes the goods to fall off the forklift, but also easily causes personal injury and damage to the forklift.

[0005] To achieve the above objectives, this application provides the following technical solution: a logistics forklift with anti-tipping function, comprising a forklift body, fixing blocks fixed on the left and right sides of the forklift body, a U-shaped seat fixed at the bottom of the fixing blocks, a drive motor mounted on the U-shaped seat, and a drive gear rotatably connected between the relative inner walls of the U-shaped seat via bearings, the drive gear being driven by the drive motor, a carrier plate slidably disposed inside the U-shaped seat, a rack fixed at the top of the carrier plate, the rack meshing with the drive gear, locking blocks fixed on the left and right sides of the carrier plate, a sliding groove for sliding the locking blocks being opened inside the U-shaped seat, a plurality of first rollers mounted at the bottom of the carrier plate, and a counterweight assembly mounted at the rear of the forklift body, the counterweight assembly being used to increase the counterweight of the forklift body.

[0006] Furthermore, a driven gear is rotatably connected between the relative inner walls of the U-shaped seat via a bearing, and the driven gear meshes with the rack.

[0007] Furthermore, limit baffles are fixed at both the front and rear ends of the carrier plate.

[0008] Furthermore, the forklift body and the two loading platforms are arranged in parallel.

[0009] Furthermore, the counterweight assembly includes an electric push rod, which is installed at the rear of the forklift body. A load block is installed at the output end of the electric push rod, a counterweight block is fixed to the top of the load block, and two second rollers are installed at the bottom of the counterweight block.

[0010] Furthermore, two fixed cylinders are fixed to the bottom of the counterweight block, and an adjusting rod is slidably inserted into the opening of the fixed cylinder. The outer end of the adjusting rod is fixedly installed at the rear of the forklift body.

[0011] In summary, the technical effects and advantages of this utility model are as follows:

[0012] In this invention, after the forklift body lifts the goods off the ground, the drive motor can be activated to drive the drive gear to rotate, so that the drive gear meshes with the rack and drives the rack to extend towards the front of the forklift body. In this way, the carrier plate and the first roller at its bottom can move with the rack to directly under the goods, forming a more stable support for the goods in conjunction with the forklift body. This ensures that even if the center of gravity changes after the forklift body lifts the goods, it can remain stable and will not tip over, thus ensuring the safety of logistics transportation.

[0013] In this invention, an electric push rod can be used to push the counterweight away from the forklift body, so that when the forklift body lifts goods, the counterweight can change the center of gravity position in conjunction with the forklift body, preventing the rear of the forklift body from tilting up. The two second rollers can not only support the counterweight, but also facilitate the electric push rod to move the counterweight. The use of the fixed cylinder and the adjusting rod can distribute the force on the second rollers and improve the stability of the counterweight during use. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example: Reference Figure 1-5 The forklift shown includes a forklift body 1, with fixed blocks 2 on both the left and right sides of the forklift body 1. A U-shaped seat 3 is fixed to the bottom of each fixed block 2, and a drive motor 4 is mounted on the U-shaped seat 3. A drive gear 5 and a driven gear 10 are rotatably connected between the relatively inner walls of the U-shaped seat 3 via bearings. The drive gear 5 is driven by the drive motor 4. A carrier plate 6 is slidably disposed inside the U-shaped seat 3. The forklift body 1 and the two carrier plates 6 are arranged parallel to each other, allowing the two carrier plates 6 to move only in the forward and backward directions of the forklift body 1. A rack 7 is fixed to the top of the carrier plate 6, and both the drive gear 5 and the driven gear 10 mesh with the rack 7. The driven gear 10 can be used to separate... The force of the loose block 8 is borne by the left and right sides of the carrier plate 6. The U-shaped seat 3 has a sliding groove for the sliding of the block 8. The two blocks 8 can ensure the stability of the connection between the U-shaped seat 3 and the carrier plate 6, so that the carrier plate 6 will not tilt when subjected to force. Multiple first rollers 9 are installed at the bottom of the carrier plate 6. The use of multiple first rollers 9 can not only support the carrier plate 6, but also facilitate the movement of the carrier plate 6. Limiting baffles 11 are fixed at the front and rear ends of the carrier plate 6. The two limiting baffles 11 can prevent the U-shaped seat 3 from completely separating from the carrier plate 6, and can also prevent the rack 7 from completely separating from the drive gear 5. A counterweight assembly is installed at the rear of the forklift body 1. The counterweight assembly is used to increase the counterweight of the forklift body 1.

[0023] After the forklift body 1 lifts the goods off the ground, the drive motor 4 can be activated to drive the drive gear 5 to rotate, so that the drive gear 5 meshes with the rack 7, causing the rack 7 to extend towards the front of the forklift body 1. In this way, the carrier plate 6 and its bottom first roller 9 can move with the rack 7 to directly under the goods, forming a more stable support for the goods in conjunction with the forklift body 1. This ensures that even if the center of gravity changes after the forklift body 1 lifts the goods, it can remain stable and will not tip over, thus ensuring the safety of logistics transportation. The drive motor 4 drives the drive gear 5 to rotate, which can cause the rack 7 to change its position and prevent the rack 7 from interfering with the normal lifting of wider goods by the forklift body 1.

[0024] The counterweight assembly includes an electric push rod 12, which is installed at the rear of the forklift body 1. A carrier block 13 is installed at the output end of the electric push rod 12. A counterweight block 14 is fixed at the top of the carrier block 13. Two second rollers 15 are installed at the bottom of the counterweight block 14. Two fixed cylinders 16 are fixed at the bottom of the counterweight block 14. An adjusting rod 17 is slidably inserted into the opening of the fixed cylinder 16. The outer end of the adjusting rod 17 is fixedly installed at the rear of the forklift body 1.

[0025] The electric push rod 12 can be used to push the counterweight 14 away from the forklift body 1, so that when the forklift body 1 lifts goods, the counterweight 14 can change the center of gravity position in conjunction with the forklift body 1, preventing the rear of the forklift body 1 from tilting up. The two second rollers 15 can not only support the counterweight 14, but also facilitate the electric push rod 12 to push the counterweight 14 to move. The use of the fixed cylinder 16 and the adjusting rod 17 can distribute the force on the second rollers 15 and improve the stability of the counterweight 14 during use.

[0026] Working principle of this utility model:

[0027] The operator moves the forklift body 1 to the location of the goods. The operator then moves the forks on the forklift body 1 to the bottom of the goods. To prevent the rear of the forklift body 1 from tilting up due to excessive weight, the electric push rod 12 can be extended in advance. This push rod 12 pushes the counterweight block 14 away from the forklift body 1 via the second roller 15. In this way, the counterweight block 14, together with the forklift body 1, can lift the goods off the ground, ensuring that the rear of the forklift body 1 will not tilt up after the center of gravity changes. When the forklift body 1 is not picking up goods, the electric push rod 12 is in the retracted state. At this time, the distance between the counterweight block 14 and the forklift body 1 is small, reducing the space occupied.

[0028] After the goods are lifted, in order to further ensure the safety of the forklift body 1 when transferring goods, the drive motor 4 can be operated to drive the drive gear 5 to rotate. The drive gear 5 drives the rack 7 to move, so that the rack 7, the carrier plate 6 and multiple first rollers 9 move directly under the goods. In this way, a more stable support shape can be formed for the goods, ensuring that the forklift body 1 will not tip over when the goods are transferred, thus ensuring the safety of logistics transportation. The rack 7 is folded at a slightly rear position when the forklift body 1 picks up the goods, in order to prevent the rack 7 from interfering with the normal picking up of goods by the forks on the forklift body 1.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
