Description

Technical Field

[0001] This utility model relates to the field of forklift technology, specifically to a remotely controlled rear-wheel steering forklift. Background Technology

[0002] In modern logistics, warehousing, and various industrial production scenarios, forklifts, as key material handling equipment, play a vital role in improving the efficiency of loading, unloading, transportation, and stacking of goods. As industries continuously increase their demands for production efficiency and safety, higher requirements are being placed on the ease of operation, maneuverability, and adaptability of forklifts.

[0003] Traditional forklifts are typically operated manually on-site. Operators sit in the driver's seat and use steering wheels, joysticks, and other control devices to drive, steer, and move goods. However, this method has limitations. In hazardous work environments, such as in chemical production where flammable, explosive, toxic, or hazardous materials are being handled, or when working in areas with high shelving, operators face significant safety risks. Furthermore, the operator's field of vision may be limited, preventing a comprehensive view of the surrounding environment. This can lead to collisions, scrapes, and other accidents, impacting operational safety and efficiency. While front-wheel steering forklifts can meet basic steering needs in spacious work areas, their larger turning radius results in insufficient maneuverability in narrow warehouse aisles or complex work scenarios. For example, when moving goods between densely packed shelves, such forklifts require multiple steering adjustments to accurately reach the target location. This not only increases operation time and reduces efficiency but can also accelerate equipment wear due to frequent turning. Utility Model Content

[0004] The purpose of this invention is to provide a remotely controlled rear-wheel steering forklift for easy adjustment, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a remotely controlled rear-wheel steering convenient control forklift, including a vehicle body, an installation groove is provided below the vehicle body, a steering assembly is provided inside the installation groove, the steering assembly includes a rotating shaft and a fixed plate, the fixed plate is fixed inside the installation groove, several fixed rods are fixed below the fixed plate, a base plate is fixed below the several fixed rods, a hydraulic motor is fixed below the base plate, a drive gear is fixed on the output shaft of the hydraulic motor, the rotating shaft is rotatably disposed between the fixed plate and the base plate, a driven gear is fixed on the rotating shaft, and the driven gear meshes with the drive gear.

[0006] A transmission gear is fixed on the rotating shaft, and the transmission gear is located below the driven gear. A signal receiver is fixed on the base plate, and the signal receiver is electrically connected to the hydraulic motor.

[0007] With the above structure, the hydraulic motor drives the drive gear to rotate through the output shaft, the drive gear drives the driven gear to rotate, and the driven gear drives the rotating shaft to rotate.

[0008] The steering assembly also includes a rotating disk, which is rotatably mounted on a base plate. A ring gear is fixed above the rotating disk, and belts are provided on the ring gear and the transmission gear. A steering shaft is fixed below the rotating disk.

[0009] With the above structure, the rotating shaft drives the transmission gear to rotate, the transmission gear drives the ring gear to rotate via a belt, the ring gear drives the rotating disk to rotate, and the rotating disk drives the steering shaft to rotate.

[0010] The steering shaft is T-shaped, and two steering wheels are rotatably mounted on the steering shaft.

[0011] The above structure, with its T-shaped steering shaft and two rotating steering wheels, provides more stable support, ensuring that the two steering wheels maintain a relatively stable position and trajectory during rotation. The two steering wheels enable the forklift's rear wheels to achieve flexible steering operations, improving the forklift's stability and maneuverability during driving and turning, and better adapting to different working environments and operational needs.

[0012] A control console and grippers are fixed on the top of the vehicle body, and two wheels are installed on the bottom of the vehicle body.

[0013] With the above structure, the control console facilitates the operation and monitoring of the forklift's running status, and also allows the operator to input various operating commands and view operating parameters. The grippers are the core components of the forklift to realize the function of handling goods, and can grab and place goods to complete the basic operating tasks of the forklift. The two wheels and the steering wheels work together to form the complete driving system of the forklift, enabling the forklift to move normally on the ground and perform various steering operations.

[0014] Compared with the prior art, the beneficial effects of this utility model are: By combining the vehicle body and steering components, remote control operation is achieved, eliminating the need for an operator in the driver's seat. This frees the operator from limited visibility, allowing for a comprehensive view of the surrounding environment and preventing accidents such as collisions and scratches during operation. Simultaneously, this design enables the forklift to turn with a small turning radius in narrow warehouse aisles or complex operating environments, accurately reaching the target location without multiple steering adjustments. This not only shortens operation time but also improves operational efficiency. Attached Figure Description

[0021] The steering shaft 9 is T-shaped, and two steering wheels 6 are rotatably mounted on the steering shaft 9. The T-shaped structure of the steering shaft 9 with two steering wheels 6 provides more stable support, ensuring that the two steering wheels 6 maintain a relatively stable position and movement trajectory during rotation. The two steering wheels 6 enable the rear wheels of the forklift to achieve flexible steering operation, improving the stability and maneuverability of the forklift during driving and turning, and better adapting to different working environments and operational needs.

[0022] The control console 1 and gripper 5 are fixed on the top of the vehicle body 2, and two wheels 4 are installed on the bottom of the vehicle body 2.

The two wheels 4 cooperate with the steering wheels 6 to form the complete driving system of the forklift, enabling the forklift to move normally on the ground and perform various steering operations.

[0023] Working principle: The remote control sends a signal to the signal receiver 15, which then sends the signal to the hydraulic motor 16. The hydraulic motor 16 drives the drive gear 18 to rotate via the output shaft. The drive gear 18 drives the driven gear 11 to rotate, which in turn drives the rotating shaft 12 to rotate. The rotating shaft 12 drives the transmission gear to rotate, which in turn drives the ring gear 7 to rotate via the belt 8. The ring gear 7 drives the rotating disc 17 to rotate, which in turn drives the steering shaft 9 to rotate. The steering shaft 9 drives the two steering wheels 6 to rotate. This system eliminates the need for an operator in the driver's seat, ensuring unrestricted visibility and allowing for a comprehensive view of the surrounding environment. This avoids accidents such as collisions and scratches caused by limited visibility. Furthermore, in narrow warehouse aisles or complex work environments, the forklift can turn with a small turning radius, accurately reaching the target position without multiple direction adjustments. This not only reduces operation time but also improves work efficiency.
