Description

Technical Field

[0001] This utility model relates to the field of unmanned forklift technology, specifically a forklift designed to prevent excessive stacking. Background Technology

[0002] The intelligent forklift is an industrial vehicle robot that integrates AGV automatic navigation, IoT platform scheduling, multi-sensor fusion algorithms, and barcode technology. It achieves autonomous path planning, cargo identification, handling, and stacking functions through LiDAR, computer vision, wireless communication, and data acquisition technologies. Its core system consists of a scheduling platform and a navigation module (supporting six technologies including natural navigation, laser navigation, and QR code scanning). Equipped with safety radar, a 3D camera, and BSD blind spot monitoring, it can reduce accident rates and adapt to working environments ranging from -10°C to 40°C.

[0003] Existing unmanned forklifts lack structures to limit the height of goods during transport, making it easy to load excessively tall items. This results in an excessively high center of gravity for both the goods and the forklift, increasing the risk of tipping over. Furthermore, existing forklifts lack devices to measure the tilt angle of the forklift in both directions and the fork arms, making it impossible to measure the tilt angle after loading goods in real time, which further increases the risk during forklift movement. Utility Model Content

[0004] The technical problem this invention aims to solve is to overcome existing defects and provide a forklift that prevents excessive stacking. By incorporating an ultrasonic level sensor and an audible and visual alarm, when the forklift is loading goods, if the height of the goods exceeds the ultrasonic level sensor's set value, the ultrasonic level sensor can detect this and trigger an alarm via the audible and visual alarm. This prevents the forklift from loading goods too high, reduces the risk of forklift and goods tipping over, and effectively solves the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a forklift for preventing excessive stacking, comprising an unmanned forklift, wherein a third tilt sensor is provided on one side of the lower part of the unmanned forklift, a first tilt sensor is provided on the other side of the lower part of the unmanned forklift, and a U-shaped support frame is symmetrically arranged on the side of the unmanned forklift away from the third tilt sensor. An ultrasonic level sensor is fixedly connected to the upper outer side of the support frame, and a fork arm is connected to the support frame by a chain. A second tilt sensor is provided on the lower side of the fork arm, and a protective baffle is fixedly connected to the fork arm below the second tilt sensor.

[0006] Furthermore, a limit baffle is provided at the vertical position of the fork arm root, and a limit sensor is installed on the inner side of the vertical structure of the fork arm corresponding to the area where the limit baffle rotates to the vertical position.

[0007] Furthermore, a navigation radar is installed on the upper side of the horizontal plate at the upper end of the support frame, and an obstacle avoidance radar is installed on the lower side of the third tilt sensor.

[0008] Furthermore, a touch screen is installed on the inclined surface of the upper part of the unmanned forklift, and an adjustment button is provided on one side of the touch screen.

[0009] Furthermore, a support wheel is installed on the support arm on the lower side of the fork arm, and an audible and visual alarm is installed on the lower side of the navigation radar.

[0010] Furthermore, the unmanned forklift has three drive wheels on its lower side.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, through the installation of an ultrasonic level sensor and an audible and visual alarm, enables the ultrasonic level sensor to detect when the height of the goods exceeds the set value during loading, and to trigger an alarm via the audible and visual alarm, thereby preventing the forklift from loading goods too high and reducing the risk of the forklift and goods tipping over.

[0013] 2. This utility model, through the installation of tilt sensors No. 1, No. 2 and No. 3, enables real-time measurement of the tilt angle of the unmanned forklift in two directions after the forklift is loaded with goods, and also measures the tilt angle of the forklift in real time, thereby providing timely alarm reminders and reducing the risks during the movement of the forklift after loading goods.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 This embodiment provides a technical solution: a forklift for preventing excessive stacking, including an unmanned forklift 1. A third tilt sensor 14 is installed on one side of the lower part of the unmanned forklift 1, and a first tilt sensor 11 is installed on the other side of the lower part of the unmanned forklift 1. A U-shaped support frame 2 is symmetrically arranged on the side of the unmanned forklift 1 away from the third tilt sensor 14. An ultrasonic level sensor 9 is fixedly connected to the upper outer side of the support frame 2. A fork arm 3 is connected to the support frame 2 by a chain. A second tilt sensor 12 is installed on the lower side of the fork arm 3. A protective baffle 13 is fixedly connected to the fork arm 3 below the second tilt sensor 12.

[0020] like Figure 1-3 As shown, the fork arm 3 can lift the goods from the shelf below. When the goods are placed on the fork arm 3 and the fork arm 3 moves to the bottom, the ultrasonic level sensor 9 can detect whether the goods exceed the set height. When the height of the goods exceeds the set value, the audible and visual alarm 10 will sound an alarm, and then the goods will be unloaded. This avoids the center of gravity of the unmanned forklift 1 and the goods from becoming too high when the height of the goods exceeds the set value, thereby reducing the risk of the unmanned forklift 1 and the goods tipping over. During the movement of the unmanned forklift 1 and the goods, the first tilt sensor 11 and the third tilt sensor 14 can detect the tilt angle of the unmanned forklift 1 in two directions in real time, and the second tilt sensor 12 can detect the tilt angle of the fork arm 3. This allows the tilt angle of the unmanned forklift 1 to be monitored in real time during the movement. When the tilt angle exceeds the set value, the audible and visual alarm 10 will sound an alarm, reducing the risk of the unmanned forklift 1 moving.

[0021] A limit baffle 15 is provided at the vertical position of the root of the fork arm 3, and a limit sensor is installed on the inner side of the vertical structure of the fork arm 3 in the area where the limit baffle 15 is rotated to the vertical position.

[0022] A navigation radar 6 is installed on the upper side of the horizontal plate at the top of the support frame 2, and an obstacle avoidance radar 5 is installed on the lower side of the third tilt sensor 14.

[0023] A touch screen 7 is installed on the sloping surface on the upper part of the unmanned forklift 1, and an adjustment button 8 is set on one side of the touch screen 7.

[0024] A support wheel 4 is installed on the support arm under the fork arm 3, and an audible and visual alarm 10 is installed under the navigation radar 6.

[0025] The unmanned forklift has three drive wheels on its lower side.

[0026] The working principle of a forklift for preventing excessive stacking provided by this utility model is as follows: Figures 1-3 As shown, the fork arm 3 can lift the goods from the shelf below. When the goods are placed on the fork arm 3 and the fork arm 3 moves to the bottom, the ultrasonic level sensor 9 can detect whether the goods exceed the set height. When the height of the goods exceeds the set value, the audible and visual alarm 10 will sound an alarm, and then the goods will be unloaded. This avoids the center of gravity of the unmanned forklift 1 and the goods from becoming too high when the height of the goods exceeds the set value, thereby reducing the risk of the unmanned forklift 1 and the goods tipping over. During the movement of the unmanned forklift 1 and the goods, the first tilt sensor 11 and the third tilt sensor 14 can detect the tilt angle of the unmanned forklift 1 in two directions in real time, and the second tilt sensor 12 can detect the tilt angle of the fork arm 3. This allows the tilt angle of the unmanned forklift 1 to be monitored in real time during the movement. When the tilt angle exceeds the set value, the audible and visual alarm 10 will sound an alarm, reducing the risk of the unmanned forklift 1 moving.
