Description

Technical Field

[0001] The utility model relates to the technical field of internal combustion counterbalanced forklifts, and particularly to a forklift with stepless adjustment function. Background Art

[0002] Internal combustion counterbalanced forklifts are devices widely used in the fields of logistics, manufacturing, and warehousing, and are designed to provide efficient cargo loading, unloading, and handling capabilities.

[0003] The existing Chinese patent (Publication No.: CN204454456U) proposes a forklift. The key points of its technical solution are a forklift including a forklift body, where the forklift body includes a handling part and an operating part. A protective device is connected between the handling part and the operating part. The protective device includes a guardrail and a connecting frame. The guardrail includes a horizontal plate and several baffle plates. The horizontal plate is fixedly connected to the connecting frame. One end of each baffle plate is fixedly connected to the connecting frame, and the other end is fixedly connected to the horizontal plate. A connecting groove detachably matched with the connecting frame is provided on the handling part or the operating part.

[0004] Due to the possible bumpy phenomenon during the handling journey in the above technical solution, the goods may tilt towards the operating part. Due to the existence of the guardrail, it can effectively prevent the goods from tilting towards the operator, improving the safety of the operator during the operation. And due to the existence of the strengthening part, it can strengthen the strength of the guardrail, enabling the guardrail to have sufficient strength to support the tilted goods, further improving the safety of the operator during the operation.

[0005] However, a limiting component is not provided on the side far from the driver in the above device. During transportation, the goods are likely to shake or even fall due to operations such as vibration, sudden stop, or turning. Without a limiting component, it is necessary to frequently check and confirm the stability of the goods, and the operation speed will be affected, thus reducing the overall operation efficiency. Therefore, we propose a forklift with stepless adjustment function. Summary of the Utility Model

A second motor 53 is arranged on the top of the slide rail 51. The output end of the second motor 53 is fixedly connected to a lead screw 52. The lead screw 52 is rotatably connected in the slide rail 51. A top plate 54 is arranged on the slide rail 51. The top plate 54 is connected to a second slider in the slide rail 51. A chute 6 is opened on the top of the top plate 54. A first slider 56 is slidably connected in the chute 6. A limiting plate 55 is connected to the bottom of the first slider 56. A fixed plate 7 is arranged on the first bracket 2. A first electric telescopic rod 58 is arranged on the fixed plate 7. A connecting rod 59 is rotatably connected to the first electric telescopic rod 58. One end of the connecting rod 59 away from the first electric telescopic rod 58 is connected to the first slider 56. A locking plate 57 is arranged on the top plate 54. By setting the limiting component 5, when the first electric telescopic rod 58 is turned on, the connecting rods 59 on both sides are driven to move. The connecting rods 59 drive the first slider 56 to slide in the chute 6. The first slider 56 drives the limiting plate 55 at the bottom to fit with the goods, so as to limit the goods. The locking plate 57 is set to limit the side of the goods away from the driver;

[0034] Furthermore, as Figure 3 shown: On one side of the top plate 54 close to the locking plate 57, a flipping assembly 8 is provided. The flipping assembly 8 includes a housing 81. A clamping groove 83 is formed on the top plate 54. A rotating rod 82 is rotatably connected in the clamping groove 83. A third motor is arranged in the housing 81. The rotating rod 82 is fixedly connected to the output end of the third motor. By providing the flipping assembly 8, when the third motor is started, the rotating rod 82 is driven to rotate, and the rotating rod 82 drives the locking plate 57 to rotate. When unloading is required, the locking plate 57 can be retracted, and when transporting, the locking plate 57 is put down;

[0035] In the above solution, there is also a problem that the distance between the fork arms 3 should be adjustable according to the size of the goods, as Figure 2 shown: The adjusting assembly 4 includes a second bracket 41. A first motor 42 is arranged on the second bracket 41. The output end of the first motor 42 is fixedly connected to a screw rod 43. A sliding member 44 is sleeved on the screw rod 43. The bottom of the sliding member 44 is connected to the fork arm 3. By providing the adjusting assembly 4, when the first motor 42 is started, the screw rod 43 is driven to rotate, and the screw rod 43 drives the sliding member 44 and the fork arm 3 to be adjusted, so that the distance between the two fork arms 3 can be adjusted according to the size of the goods;

[0036] In the above solution, there is also a problem that when there is no defined forklift chassis, it is not convenient to unload goods, as Figure 2 and Figure 4 shown: A boosting assembly 9 is arranged on one side of the first bracket 2 close to the fork arm 3. The boosting assembly 9 includes a connecting plate 91. A second electric telescopic rod 92 is arranged on one side of the connecting plate 91 close to the fork arm 3. A ball 10 is arranged on the bottom of the top plate 54 close to the limiting plate 55. By providing the boosting assembly 9, the problem of inconvenient unloading when there is no defined forklift chassis is prevented. By providing the ball 10, it assists in unloading and reduces the friction generated during unloading;

[0037] Furthermore, as Figure 1 shown: A seat 12 is arranged on the top of the vehicle body 1. A protective frame 13 is arranged on one side of the top of the vehicle body 1 close to the seat 12. Wheels 14 are arranged at the bottom of the vehicle body 1. By providing the protective frame 13, the head of the driver is protected to prevent the goods from falling and causing harm to the staff.

[0038] Working principle: As Figure 1 - Figure 4As shown in the figure, first, start the first motor 42 to drive the screw rod 43 to rotate. The screw rod 43 drives the sliding member 44 and the fork arm 3 to adjust, and the distance between the two fork arms 3 can be adjusted according to the size of the goods. Then, lift the goods. Before transportation, start the first electric telescopic rod 58 to drive the connecting rods 59 on both sides to move. The connecting rods 59 drive the first slider 56 to slide in the chute 6. The first slider 56 drives the limit plate 55 at the bottom to fit with the goods to limit the goods. The locking plate 57 is provided to limit the side of the goods away from the driver. When unloading at the designated position, start the third motor to drive the rotating rod 82 to rotate. The rotating rod 82 drives the locking plate 57 to rotate to prevent blocking the unloading. If there is no defined forklift chassis, when it is inconvenient to unload, by setting the boosting component 9, it can prevent the problem of inconvenient unloading when there is no defined forklift chassis. By setting the ball 10, it can assist in unloading and reduce the friction generated during unloading.
