Referring to fig. 1, the unloading and loading vehicle comprises a vehicle body 9, a support frame 91 for supporting cargos is rotatably arranged on the vehicle body 9, the support frame 91 comprises a first support part 911 vertically arranged and a second support part 912 horizontally arranged, and the second support part 912 is connected with the lower end of the first support part 911. The first support portion 911 and the second support portion 912 make the support frame 91 in an L-shape as a whole. The second support portion 912 is provided with a tongue plate 92 in a sliding manner, a first hydraulic cylinder 93 is arranged on one side of the tongue plate 92 close to the first support portion 911, the first hydraulic cylinder 93 is rotatably connected with the support frame 91, and the tongue plate 92 is connected with a piston rod of the first hydraulic cylinder 93. The vehicle body 9 is provided with a second hydraulic cylinder 94, and a piston rod of the second hydraulic cylinder 94 is rotatably provided with the first support part 911.

The end of the second support portion 912 remote from the first support portion 911 is regarded as the front end of the vehicle body 9, and the end of the first support portion 911 remote from the second support portion 912 is regarded as the rear end of the vehicle body 9. After loading the goods, the vehicle body 9 moves forwards, which means that the front end of the vehicle body 9 is positioned in front of the moving direction; on the other hand, the vehicle body 9 travels backward, meaning that the rear end of the vehicle body 9 is located forward in the traveling direction.

The embodiment of the application discloses control system of door plant unloading car.

Example 1

Referring to fig. 1 and 2, a control system of a door panel unloading vehicle includes a controller 1, a camera 2, a display 3, a distance sensor 4, and a load sensor 6. The camera 2 is arranged below the front end of the vehicle body 9 and is used for shooting images in front of the vehicle body 9 when the vehicle body 9 moves forwards; the camera 2 is electrically connected to the display 3, and transmits the captured image to the display 3. The display 3 is used for receiving the images transmitted by the camera 2 and displaying the images on the display 3 for the workers to view. The workman is when the transportation door plant is isometric great, high higher goods, looks over the road conditions in automobile body 9 the place ahead in real time through display 3 to guarantee the walking security of unloading the car. Because the workman can look over the road conditions in front of automobile body 9 in real time, just also need not to drive automobile body 9 and move backward, make automobile body 9 reach the unloading position after, can directly unload, need not rotatory automobile body 9, convenient and fast helps improving handling efficiency.

Referring to fig. 1 and 2, a controller 1 is electrically connected to a camera 2 for controlling the turning on and off of the camera 2. The controller 1 can be an MCU, a singlechip or a PLC control system. The controller 1 and the display 3 are both mounted at the rear end of the vehicle body 9, so that a worker can operate the controller 1 and view images on the display 3 when the vehicle body 9 is walking forward.

Referring to fig. 1 and 2, the distance sensor 4 is mounted on the front end of the vehicle body 9 and electrically connected to the controller 1. The distance sensor 4 is configured to detect a distance between an object in a traveling direction of the vehicle body 9 and a front end of the vehicle body 9, thereby generating distance data and transmitting the distance data to the controller 1. In particular, the distance sensor 4 may be an infrared sensor, a proximity sensor or a radar sensor.

After receiving the distance data transmitted from the distance sensor 4, the controller 1 controls the vehicle body 9 to stop according to the distance data. Specifically, a distance threshold is preset in the controller 1, and the distance threshold is set manually, for example, in this embodiment, the distance threshold is equal to the length of the tongue plate 92; in another embodiment, the distance threshold may also be greater than the length of the tongue plate 92 and less than 1.5 times the length of the tongue plate 92. When the distance data received by the controller 1 is equal to or less than the distance threshold, the controller 1 controls the vehicle body 9 to decelerate and stop. On one hand, when an obstacle suddenly appears on the running path of the vehicle body 9, a worker cannot stop the vehicle in time, and the controller 1 brakes the vehicle body 9, so that the safety is improved conveniently; on the other hand, when the vehicle body 9 travels to the loading position or the unloading position, the controller 1 can control the vehicle body 9 to decelerate and stop without a worker manually braking the vehicle body 9, which contributes to improvement of the position control accuracy of the vehicle body 9, thereby facilitating loading or unloading.

Referring to fig. 1 and 2, the distance sensor 4 is electrically connected with an alarm 5, and the alarm 5 is used for receiving the distance data transmitted by the distance sensor 4 and giving an alarm when the distance data is equal to or less than a preset distance threshold. Note that the distance threshold in the alarm 5 is the same as the distance threshold in the controller 1. The alarm 5 may be provided separately from the distance sensor 4, may be integrated in the distance sensor 4, or may use the distance sensor 4 having an alarm function.

Referring to fig. 1 and 2, a load sensor 6 is mounted on the vehicle body 9 for detecting a load of a cargo on the vehicle body 9 and generating load data. In the present embodiment, the load sensor 6 is installed below the second support portion 912 for detecting the load on the support bracket 91. The load cell 6 may be a load cell or a pressure sensor, and the load cell 6 is electrically connected to the controller 1 for transmitting load data to the controller 1. The controller 1 is configured to receive the load data and control the traveling speed of the vehicle body 9 based on the load data. Specifically, the larger the load is, the smaller the running speed is, so that the running safety of the unloading vehicle and the stability of goods are ensured conveniently. When the unloading vehicle is unloaded, the controller 1 controls the running speed of the vehicle body 9 to reach the maximum value, so that the vehicle body 9 can move quickly, and the unloading efficiency is improved.

The implementation principle of the embodiment 1 is as follows: when the goods need to be loaded, the worker drives the vehicle body 9 to move to the position near the goods, the distance sensor 4 continuously transmits distance data to the controller 1, and when the front end of the vehicle body 9 is only one tongue plate 92 away from the goods, the controller 1 controls the vehicle body 9 to stop. Then the controller 1 controls the tongue plate 92 to extend, and a worker loads goods onto the vehicle body 9; during which the load sensor 6 continuously transmits load data to the controller 1.

After the loading is completed, the controller 1 limits the maximum traveling speed of the vehicle body 9 based on the load data, and the worker drives the vehicle body 9 to move to the unloading position. During which the worker views the road condition on the traveling path of the vehicle body 9 through the display 3 to ensure safe traveling of the vehicle body 9.

When the vehicle body 9 moves to the vicinity of the unloading position and the front end of the vehicle body 9 is separated from the unloading position by only one length of the tongue plate 92, the controller 1 controls the vehicle body 9 to stop and simultaneously controls the tongue plate 92 to retract. The goods on the tongue plate 92 automatically fall to the unloading area, so that the loading and unloading efficiency is improved.
