Description

Technical Field

[0001] The utility model relates to the technical field of speed limiting equipment, in particular to a forklift speed limiting device. Background Art

[0002] The authorization announcement number CN210416229U discloses a forklift speed limit alarm device, which is provided with an oil supply pipeline; a throttle valve connected in series on the oil supply pipeline; a speed regulating alarm installed on the locomotive, and the speed regulating alarm is electrically connected to the control end of the throttle valve. The speed regulating alarm can be used to detect the running speed of the forklift, and the speed regulating alarm can be used to control and alarm the running speed of the forklift. Once the forklift travels at a speed exceeding the set speed, the alarm will raise the alarm of "you have exceeded the speed limit", and the throttle valve will limit the amount of oil entering the accelerator to ensure that the upper limit of the forklift speed does not exceed the set speed, which greatly improves the safety factor of the forklift travel process.

[0003] The working principle of the device is to use the throttle valve to control the oil intake of the accelerator to ensure that the upper limit of the forklift speed does not exceed the set speed. However, when installing the device, the throttle valve needs to be installed on the oil supply pipeline on the forklift, and the oil supply pipeline on the forklift needs to be modified, which makes the installation too complicated. Therefore, we propose a forklift speed limiter. Utility Model Content

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0024] Reference Figure 1-4 A forklift speed limiting device includes a forklift accelerator pedal 1 and a speed meter 2. An active speed limiting structure for the forklift is arranged on the right side of the forklift accelerator pedal 1. The active speed limiting structure for the forklift includes an assembly component that can be assembled with the forklift accelerator pedal 1 as a whole, and a throttle reset assembly arranged on the right side of the forklift accelerator pedal 1.

[0025] The assembly component includes a clamping frame 3, the upper surface of which is threadedly connected with an assembly bolt 4, the lower end of which extends to the inner wall of the clamping frame 3 and is fixedly connected with a clamping plate 5. The clamping frame 3 is placed on the forklift throttle pedal 1, and then the assembly bolt 4 is tightened, thereby driving the clamping plate 5 to clamp the forklift throttle pedal 1.

[0026] The throttle reset assembly includes a mounting box 6, on the surface of which a mounting plate 14 is fixedly mounted. A mounting hole is provided on the surface of the mounting plate 14, and a self-tapping screw is passed through the mounting hole so that the mounting box 6 can be fixed in the forklift cab. At this time, the mounting box 6 is on the right side of the forklift throttle pedal 1.

[0027] A guide rod 7 is fixedly connected to the inner wall of the installation box 6, and a slider 8, a compression spring 9 and an electromagnet 10 are respectively sleeved on the surface of the guide rod 7. The electromagnet 10 is fixedly installed on the inner left side wall of the installation box 6, and an iron ring 11 is fixedly connected to the left side of the slider 8. One end of the compression spring 9 is fixedly connected to the inner right side wall of the installation box 6, and the other end of the compression spring 9 is fixedly connected to the right end of the slider 8. The compression spring 9 can drive the iron ring 11 close to the electromagnet 10 in the initial state.

[0028] An adjustable support rod is hinged at the upper end of the slider 8, and the end of the adjustable support rod away from the slider 8 is hinged to the lower end of the clamping frame 3. The adjustable support rod is composed of a threaded barrel 12 and a threaded rod 13 threadedly connected to the inner wall of the threaded barrel 12. The end of the threaded rod 13 away from the threaded barrel 12 is hinged to the surface of the slider 8, and the end of the threaded barrel 12 away from the threaded rod 13 is hinged to the lower end of the clamping frame 3.

[0029] When the installation box 6 is fixed to the right side of the forklift accelerator pedal 1, the threaded rod 13 is rotated, and the screw transmission between the threaded rod 13 and the threaded tube 12 is utilized to change the distance between the installation box 6 and the clamping frame 3, thereby changing the position and angle of the clamping frame 3, so that the clamping frame 3 can better clamp the forklift accelerator pedal 1.

[0030] The speed meter 2 is internally provided with a speed measuring unit and a control unit that can control the opening and closing of the electromagnet 10. When the forklift accelerator pedal 1 is stepped on, the adjustable support rod will push the slider 8 to slide to the right along the surface of the guide rod 7, and drive the iron ring 11 away from the electromagnet 10. When the forklift is overspeeding, the control unit inside the speed meter 2 will control the electromagnet 10 to open, and the electromagnet 10 can be used to absorb the iron ring 11, thereby driving the slider 8 to move to the left and reset. When the slider 8 moves to the left, the adjustable support rod can be used to push the forklift accelerator pedal 1 to reset, so that the operator can no longer step on the forklift accelerator pedal 1 and the forklift is in idle speed. When the forklift speed decreases, the electromagnet 10 will be closed.

[0031] Compared with the prior art, the device uses self-tapping screws to fix the installation box 6 on the right side of the forklift accelerator pedal 1, and then uses the assembly component to assemble the throttle reset component and the forklift accelerator pedal 1 into one, without changing the oil supply pipeline of the forklift, so that the device can be quickly installed.
