Description

Technical Field

[0001] The present application relates to the technical field of electric forklifts, and in particular to an anti-collision warning device for electric forklifts. Background Art

[0002] An electric forklift is powered by electricity, powered by a battery. The battery outputs electrical energy, which is converted into mechanical energy by the motor, driving the forklift's movement and raising and lowering the forks. Compared to traditional fuel-powered forklifts, electric forklifts offer numerous advantages, including ease of operation and environmental friendliness. An electric forklift consists of a chassis, lifting frame, hydraulic system, and forks.

[0003] Currently, electric forklifts are typically operated and controlled by a driver in the cab. However, in actual operation, it is found that it is difficult for the driver to maintain a safe distance from the top of the lifting frame in the cab. This makes it easy for the lifting frame to collide with objects during cargo handling, posing a certain safety hazard. Therefore, to address the above problem, the present application provides an electric forklift anti-collision warning device. Utility Model Content

[0004] In order to solve the problem that a lifting frame is prone to collision, the present application provides an anti-collision warning device for an electric forklift.

[0005] The present application provides an anti-collision warning device for an electric forklift, comprising a forklift body, a lifting frame provided on the forklift body, a fork mounted on the lifting frame, an alarm mounted on the lifting frame, an anti-collision component provided on the top of the lifting frame, the anti-collision component comprising a buffer plate, elastic members symmetrically fixedly connected to the bottom of the buffer plate, a touch-pressure switch fixedly connected to the top of the lifting frame, a protrusion fixedly connected to the bottom of the buffer plate, grooves symmetrically provided on the fork, and infrared ranging sensors fixedly connected to the inside of the grooves on both sides.

[0006] Preferably, the buffer plate is arranged on the top of the lifting frame, and the elastic members on both sides are respectively fixedly connected to the top of the lifting frame.

[0007] Preferably, the touch-pressure switch is arranged between the elastic members on both sides, and the protrusion is vertically arranged on the top of the touch-pressure switch.

[0008] Preferably, the grooves on both sides are symmetrically arranged at the bottom position of the side surface of the fork.

[0009] Preferably, the alarm is connected to the touch-pressure switch via an electric wire, and the infrared ranging sensor is connected to the alarm via an electric wire.

[0010] In summary, this application has the following beneficial technical effects:

[0011] By designing an anti-collision component, when the electric forklift is in operation, the hydraulic system on the forklift body drives the lifting frame and the forks, so that the lifting frame drives the forks to move. When a collision occurs during the lifting of the lifting frame, the elastic member rebounds and resets to relieve the force generated by the buffer plate during the collision, and the touch switch is triggered by the protrusion, so that the alarm warns the driver. At the same time, the infrared ranging sensors on both sides of the forks monitor the distance between the forks and the objects. When the distance is too small, the alarm warns the driver. Compared with the existing technology, this design can avoid the lifting frame 2 from directly colliding with objects during the lifting process, and can also warn the driver in the event of a collision, thereby effectively improving the safety of the electric forklift during operation.

[0017] The following is combined with Figure 1 - Figure 4 This application is described in further detail.

[0018] Example:

[0019] An electric forklift anti-collision warning device is used for electric forklift anti-collision warning to improve the safety of electric forklifts. Figure 1 - Figure 2, including a forklift body 1, a lifting frame 2 is provided on the forklift body 1, and a fork 3 is installed on the lifting frame 2. The lifting frame 2 and the fork 3 are existing components of the forklift body 1. The lifting frame 2 and the fork 3 are driven by the hydraulic system on the forklift body 1, so that the lifting frame 2 drives the fork 3 to move, thereby transporting the goods. An alarm 4 is installed on the lifting frame 2, and the alarm 4 model is BC-81. The alarm 4 warns the forklift driver of the risk of collision. An anti-collision component 5 is provided on the top of the lifting frame 2. The anti-collision component 5 avoids the risk of collision of the lifting frame 2 during the rising process, thereby improving the safety of the forklift when in use;

[0020] During use, the hydraulic system on the forklift body 1 drives the lifting frame 2 and the cargo forks 3, so that the lifting frame 2 drives the cargo forks 3 to move. When the lifting frame 2 is in the process of rising, the anti-collision component 5 avoids the risk of collision of the lifting frame 2 in the process of rising. At the same time, the alarm 4 warns the forklift driver of the risk of collision, thereby improving the safety of the forklift when in use.

[0021] Reference Figure 3 - Figure 4 The anti-collision component 5 includes a buffer plate 6, which is arranged on the top of the lifting frame 2. The buffer plate 6 facilitates the lifting frame 2 to buffer during a collision. The bottom of the buffer plate 6 is symmetrically fixed with an elastic member 7, and the elastic members 7 on both sides are respectively fixedly connected to the top of the lifting frame 2. The rebound reset of the elastic member 7 can alleviate the force generated by the buffer plate 6 during a collision. The top of the lifting frame 2 is fixedly connected with a touch-pressure switch 8, which facilitates the control of the alarm 4 through the touch-pressure switch 8. The touch-pressure switch 8 is arranged between the elastic members 7 on both sides. A protrusion 9 is fixedly connected to the bottom of the buffer plate 6. The protrusion 9 is vertically arranged on the top of the touch-pressure switch 8, so that after the buffer plate 6 is collided, the protrusion 9 triggers the touch-pressure switch 8. The fork 3 is symmetrically provided with a groove 10. Through the groove 10 To facilitate the installation of the infrared distance sensor 11, the grooves 10 on both sides are symmetrically arranged at the bottom position of the side of the fork 3. The infrared distance sensor 11 is fixedly connected to the inside of the grooves 10 on both sides. The model of the infrared distance sensor 11 is E18-D80NK. The infrared distance sensor 11 is used to conveniently monitor the distance between the two sides of the fork 3. The alarm 4 is connected to the touch switch 8 by wires, and the infrared distance sensor 11 is connected to the alarm 4 by wires. In the idle area of ​​this device, all the above-mentioned electrical components, which refer to the power elements, electrical components, and the adapted controller and power supply, are connected by wires. For specific connection means, refer to the following working principle. The electrical connection is completed in the working order of each electrical component. The detailed connection means are well known in the art.

[0022] When the electric forklift is in use, the hydraulic system on the forklift body 1 drives the lifting frame 2 and the cargo fork 3, so that the lifting frame 2 drives the cargo fork 3 to move. When the lifting frame 2 is in the process of rising, the elastic member 7 rebounds and resets, thereby alleviating the force generated by the buffer plate 6 during the collision, and triggers the touch switch 8 through the protrusion 9, so that the alarm 4 warns the driver. At the same time, the infrared ranging sensors 11 on both sides of the cargo fork 3 are used to conveniently monitor the distance between the cargo fork 3 and the object. When the distance is too small, the alarm 4 warns the driver.

[0023] The embodiment of the present application provides an anti-collision warning device for an electric forklift, and its working principle is as follows: when in use, the hydraulic system on the forklift body 1 drives the lifting frame 2 and the cargo fork 3, so that the lifting frame 2 drives the cargo fork 3 to move; when a collision occurs during the lifting process of the lifting frame 2, the elastic member 7 rebounds and resets to relieve the force generated by the buffer plate 6 during the collision, and the touch-pressure switch 8 is triggered by the protrusion 9, so that the alarm 4 warns the driver; at the same time, the infrared ranging sensors 11 on both sides of the cargo fork 3 are used to conveniently monitor the distance between the cargo fork 3 and the object.
