Abstract
Description
Technical Field
[0001] This utility model relates to the field of electric stacker technology, specifically to an automatic sensing and anti-collision device for electric stackers. Background Technology
[0002] In today's rapidly developing modern industrial and logistics systems, various efficient and intelligent material handling equipment have become key elements in ensuring the smooth operation of production and distribution. Among them, electric stackers, as an industrial material handling equipment driven by electricity, have been widely used in warehousing, logistics, manufacturing and many other fields due to their many advantages such as environmental protection, energy saving and flexible operation.
[0003] Existing electric stackers have the following drawbacks: the initial height of the lifting mechanism's frame structure is higher than the goods being transported. In actual operation, when the electric stacker is performing lifting operations, the operator's attention is mostly focused on the goods. They need to constantly monitor whether the goods are placed stably and whether they will slip, to ensure the safety of the goods during handling.
[0004] However, while operators are focused on the goods, the frame structure is quietly rising. Due to the initial height of the frame structure and the lack of effective monitoring and early warning mechanisms during the raising process, operators find it difficult to detect changes in the distance between the frame structure and the surrounding environment (such as the top of the warehouse, the top of the shelves, etc.). Once the frame structure rises to approach or touches an overhead obstacle, it can easily cause irreparable damage. Therefore, an automatic sensing and anti-collision device for electric stackers is needed to address this problem. Utility Model Content
[0005] The purpose of this invention is to provide an automatic sensing and anti-collision device for electric stackers to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic sensing and anti-collision device for an electric stacker, comprising a vehicle body, a lifting mechanism provided on one side of the vehicle body, the lifting mechanism comprising a fixed frame, a movable frame, hydraulic cylinders, and a first radar ranging device, the fixed frame provided on one side of the vehicle body, the movable frame being movably arranged inside the fixed frame, hydraulic cylinders being fixedly arranged on both sides inside the fixed frame, the movable ends of the hydraulic cylinders being fixedly connected to the movable frame, the first radar ranging device being fixedly arranged on both sides of the upper end of the movable frame, and a shooting mechanism being provided inside the movable frame.
[0007] Preferably, the shooting mechanism includes a fixed block, a first rotating arm, a first servo motor, a second servo motor, a second rotating arm, and a camera. A fixed block is fixedly installed on one side inside the movable frame. The first rotating arm is movably installed on the upper end of the fixed block via a rotating shaft. The first servo motor is fixedly installed on the lower end of the fixed block. The power output shaft of the first servo motor is connected to the rotating shaft where the first rotating arm is located. A second servo motor is fixedly installed on one side of the lower end of the first rotating arm. A second rotating arm is fixedly installed on the lower end of the second servo motor. A camera is fixedly installed on one side of the lower end of the second rotating arm. The shooting mechanism can capture the side of the goods away from the driver when the device is transporting and lifting goods, so as to prevent the goods from being too high and obstructing the driver's view, thus preventing the goods from colliding.
[0008] Preferably, a display screen is fixedly installed on one side of the vehicle body, and the camera is electrically connected to the display screen. The camera can transmit the captured image to the display screen, so that the driver can clearly see the side of the goods away from the driver through the display screen. The camera of this device should shoot vertically downwards.
[0009] Preferably, a second radar ranging device is fixedly installed at the upper end of the first rotating arm. The second radar ranging device can monitor the situation at the upper ends of the first and second rotating arms in real time to prevent the first and second rotating arms from hitting each other when the movable frame is raised and lowered after they are unfolded.
[0010] Preferably, a buzzer is fixedly installed on one side of the display screen. The buzzer can sound an alarm to alert the driver when the first radar ranging device and the second radar ranging device detect an abnormal distance, so as to prevent a collision with the top.
[0011] Preferably, a seat is fixedly installed inside the vehicle body, and a control knob is provided on one side of the upper end of the seat. The control knob is electrically connected to the first servo motor and the second servo motor. The rotation of the first servo motor and the second servo motor can be controlled by the control knob, thereby driving the camera to rotate and unfold.
[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model is equipped with a first radar ranging device and a second radar ranging device at the upper end of the movable frame, so that when the movable frame lifts the goods, it can monitor in real time whether there are obstacles at the top of the highest point of the lifting gantry. When the obstacle enters the threshold distance, this device can promptly use a buzzer to sound an alarm to play a collision prevention role.
[0013] 2. When this utility model is in use, the camera can capture the side of the goods away from the driver when the device is transporting and lifting the goods, so that the driver can clearly see the other side of the goods, thus preventing the goods from being too high and obstructing the driver's view, which could lead to a collision. At the same time, when the camera of this device is not in use, the first rotating arm and the second rotating arm can be rotated and folded together and stored inside the movable frame, so as not to take up space and to facilitate use.

A display screen 12 is fixedly installed on one side of the interior of the vehicle body 1. The camera 11 is electrically connected to the display screen 12. The camera 11 can transmit the captured image to the display screen 12, so that the driver can clearly see the side of the goods away from the driver through the display screen 12. The camera 11 of this device should be vertically downward for shooting. A second radar ranging device 13 is fixedly installed on the upper end of the first rotating arm 7. The second radar ranging device 13 can monitor the situation of the upper ends of the first rotating arm 7 and the second rotating arm 10 in real time to prevent the first rotating arm 7 and the second rotating arm 10 from hitting the top when the movable frame 3 is raised and lowered after the first rotating arm 7 and the second rotating arm 10 are unfolded.
