Description

Technical Field

[0001] The utility model relates to the technical field of steering, in particular to a steering structure for an electric forklift. Background Art

[0002] A forklift is a self-propelled loading and unloading conveying machinery equipped with forks and lifting devices. It is a variety of wheeled transport vehicles for loading and unloading, stacking and short-distance transportation of palletized goods. With the widespread popularization of new energy vehicles, electric forklifts have also begun to appear on the market. The steering wheel of a normal car is turned about one and a half turns, while the steering wheel of a forklift is turned about two and a half to three turns. This causes many students to be very confused when learning to drive a forklift. They don't know how many turns they have made to turn the steering wheel, or how many turns they should make to return to the center, which affects their learning effect. Utility Model Content

[0006] Through the above scheme, the mounting plate can be fixed on the forklift instrument panel through the bracket. When the steering wheel is turned, the forklift steering shaft can be driven to rotate to drive the forklift in the direction of travel. When the forklift steering shaft is turned, the circle plate can be driven to rotate. The number of circles of the circle plate is counted by the set circle number sensor, and the data is transmitted to the controller in real time. The controller displays the number of circles through the display. The forklift trainee can directly observe how many circles his steering wheel has made through the display to avoid confusion caused by circles of the steering wheel. At the same time, the threaded rod can be driven to rotate through the driving component, so that the slider moves on the inner wall of the vertical opening, thereby driving the connecting plate and the display to move, and the height of the display can be adjusted to facilitate the use of trainees of different heights.

[0007] Preferably, the driving assembly includes a rotating shaft, a second bevel gear fixed to one end of the rotating shaft, and a handle fixed to the other end of the rotating shaft.

[0008] Through the above solution, the handle can be turned to drive the rotating shaft to rotate, thereby driving the No. 2 bevel gear to rotate, and then driving the No. 1 bevel gear and the threaded rod to rotate.

[0009] Preferably, the second bevel gear is meshed with the first bevel gear.

[0010] Through the above scheme, the No. 2 bevel gear can smoothly drive the No. 1 bevel gear to rotate.

[0011] Preferably, the connecting plate is a "T"-shaped structure.

[0012] Through the above scheme, it is convenient to adjust the lifting.

[0013] Preferably, the slider is slidably connected to the inner wall of the vertical opening, a threaded through hole is opened on the outer wall at the top of the slider, and the slider is threadedly connected to the threaded rod.

[0014] With the above solution, when the threaded rod rotates, the sliding block is limited by the inner wall of the vertical opening and does not rotate along with the rotation of the threaded rod, but moves along the inner wall of the vertical opening.

[0015] Preferably, the four corners of the display are fixed to the connecting plate by bolts.

[0016] Through the above solution, the installation of the monitor is completed.

[0017] Preferably, the revolution sensor and the display are both connected to the controller via a signal line, and the controller is connected to an external power source via a power line.

[0018] Through the above scheme, the controller can control the circle sensor and the display.

[0019] The beneficial effects of the utility model are:

[0020] The mounting plate can be fixed on the forklift instrument panel by the bracket. When the steering wheel is turned, the forklift steering shaft and the circle plate can be driven to rotate. The number of circles of the circle plate can be counted by the set circle number sensor and transmitted to the controller in real time. The controller displays the number of circles through the display. The forklift trainee can directly observe how many circles his steering wheel has made through the display to avoid confusion when the steering wheel is circling. At the same time, the threaded rod can be driven to rotate by the driving component to move the slider on the inner wall of the vertical opening. The height of the display can be adjusted to facilitate use by trainees of different heights. BRIEF DESCRIPTION OF THE DRAWINGS
