The current AGV unmanned forklifts are basically equipped with many protective safety devices, such as emergency stop buttons, safety anti-collision edge, obstacle avoidance radar, etc., among which the anti-collision edge of the unmanned forklift is also It is constantly being updated.
AGV forklift is a commonly used automatic storage and transportation tool, which mainly refers to the forklift to move and stack goods on the warehouse shelves under the guidance of the computer, or to remove the goods from the shelves and move them to a designated location. The rear anti-collision device is used to detect whether the front of the AGV forklift forks hits goods, pedestrians and other obstacles. At present, the AGV forklifts on the market are rarely equipped with rear anti-collision devices. The existing rear anti-collision devices generally use Photoelectric sensors are used to detect obstacles. Although the photoelectric sensors occupy a small space, they are easily interfered by environmental factors such as dust, and are prone to false detection and shutdown, and even forks hitting people, hitting shelves, and hitting other obstacles, etc. Happening.
Technical realization elements: In order to solve the problems in the prior art, there is a forklift rear anti-collision device and an AGV forklift using the device. A rear anti-collision device for a forklift includes an inner mounting frame, an outer mounting frame, an upper cover, a detection touch panel, a photoelectric sensor, and a micro switch. Between the detection touch plate and the upper cover plate, the photoelectric sensor and the micro switch are both arranged between the upper cover plate and the inner mounting frame, and the photoelectric sensor is placed on the upper cover plate. At one end of the cover plate, one end of the detection contact plate is provided with an inner detection plate used in conjunction with the micro switch, and a tension spring is provided between the inner mounting frame and the inner mounting frame.
