Description

Technical Field

[0001] The utility model relates to the technical field of forklifts, in particular to a three-way forklift line-of-sight blind area assistance system. Background Technique

[0002] The intensive storage method of narrow aisles and high shelves has always been the mainstream direction of the Chinese warehousing industry. The three-way forklift is an excellent choice for adapting to this warehousing method. It is precisely this intensive storage method that determines that vision is extremely important for the three-way forklift. The quality of vision directly determines the difficulty of stacking operations. However, when stacking, since the operator is located on the ground and the fork position is relatively high, and the forklift mast, oil circuit, etc. inevitably cause a certain degree of obstruction to the vision, it is very difficult for the operator to grasp the relative position relationship between the fork and the shelf, resulting in difficult control of the stacking accuracy.

[0003] The usual method is to install a camera on the fork carriage to obtain the image when picking up the goods, and then transmit it through a cable to the display installed on the overhead guard. The operator can obtain the image information from this to assist in stacking. However, this way of wired data transmission determines that the wiring distance is relatively long, and during the lifting and lowering process of the fork, the cable inevitably needs to be frequently stretched and contracted, resulting in an impact on the service life of the cable. In addition, since the camera must be installed on the fork carriage, and there is still a distance between the fork and the shelf during stacking, the image obtained by the camera does not necessarily accurately reflect the relative position relationship between the fork and the shelf.

[0025] Please refer to Figures 1-4 As shown, an embodiment of the present utility model is an auxiliary system for the blind spot of vision of a three-way forklift, including an image acquisition module, a cross laser probe 1 and a video receiving terminal.

[0026] Among them, please refer to Figure 1As shown in the figure, the image acquisition module includes a mounting bracket 2, an upper wireless camera 4 integrated with a wireless transmitter 3, and a lower wireless camera 5 integrated with a wireless transmitter 3. The mounting bracket 2 is vertically installed on the forklift fork frame 6. The upper wireless camera 4 is fixedly installed at the top of the mounting bracket 2. The lower wireless camera 5 is fixedly installed at the bottom of the forklift fork frame 6. The lower wireless camera 5 is preferably arranged in the middle of the left fork 10 and the right fork 11 arranged side by side, and the lower wireless camera 5 and the upper wireless camera 4 are on the same vertical line. The cross laser probe 1 is fixedly installed on the lower wireless camera 5. Please refer to Figure 2 As shown in the figure, specifically, an interface for the cross laser probe 1 can be reserved on the lower wireless camera 5, and the cross laser probe 1 is installed in the reserved interface for the cross laser probe 1.

[0027] Please refer to Figure 1 and Figure 4 As shown in the figure, the video receiving terminal includes a display 8 integrated with a wireless receiver 7. The display 8 is arranged on the forklift overhead guard 9. The display 8 may specifically include a first display 81 and a second display 82, and the wireless receiver 7 is integrated on both the first display 81 and the second display 82; both the upper wireless camera 4 and the lower wireless camera 5 are wirelessly communicatively connected to the display 8. Specifically, the first display 81 is wirelessly communicatively connected to the upper wireless camera 4, and the first display 81 is used to display the images captured by the upper wireless camera 4. The second display 82 is wirelessly communicatively connected to the lower wireless camera 5, and the second display 82 is used to display the images captured by the lower wireless camera 5.

[0028] It should be noted that the three-way forklift line-of-sight blind area assistance system further includes a vehicle-mounted power supply module. The image acquisition module, the cross laser probe 1, and the video receiving terminal are all electrically connected to the vehicle-mounted power supply module. In specific implementation, the vehicle-mounted power supply module may include a first vehicle-mounted power supply 12 and a second vehicle-mounted power supply 13. The first vehicle-mounted power supply 12 supplies electrical energy to the upper wireless camera 4, the cross laser probe 1, and the lower wireless camera 5. The second vehicle-mounted power supply 13 supplies electrical energy to the first display 81 and the second display 82.

[0029] In addition, the cameras, cross laser probe 1, display 8, etc. adopted in this application are all common devices in the art, and those skilled in the art can easily obtain the above devices by reading the specification.

[0030] Please refer to Figure 3As shown in the figure, in the present application, a cross laser probe 1 is installed on the lower wireless camera 5, and the transmission of images no longer depends on traditional data lines. The cross laser probe 1 emits a laser beam in the horizontal and vertical directions respectively along the shooting direction of the lower wireless camera 5, and a cross light spot 14 with a certain length can be presented in the horizontal and vertical directions of the shelf or the tray. The vertical laser line light spot can intuitively provide the operator with the current position of the vehicle fork in the roadway, facilitating the operator to quickly locate the shelf position where the goods to be picked up or placed are located. The horizontal laser line light spot is captured by the camera and presented to the operator through the display 8. The operator can know how to adjust the forklift forks during the process of loading or unloading goods based on the relative position of the light spot and the shelf or the tray in the display 8.

[0031] Therefore, when using a forklift to pick up goods, the cross light spot 14 ensures the speed and accuracy during picking. However, when the forklift picks up goods for stacking, the lower wireless camera 5 and the cross laser probe 1 will be blocked by the goods and lose their functions, and the information captured by the lower wireless camera 5 cannot be transmitted to the operator. At this time, the upper wireless camera 4 installed on the upper part of the forklift fork frame 6 with an installation height higher than the height of the goods can present the spacing relationship between the goods and the shelf crossbeam to the operator through the display 8. The operator can adjust the lifting position of the tray based on the information in the display 8 to ensure the safe stacking of the goods.

[0032] It should be noted that the cross laser used in the present application is a green laser. Since the shelf crossbeams, columns and trays are mostly orange or blue, the use of a green laser results in a significant color difference, which is convenient for the operator to identify. The green laser is just one type of laser application. The use of a red or other eye-catching color laser also falls within the protection scope of this patent.

[0033] In summary, by utilizing the auxiliary functions of the cross laser probe 1 and the upper wireless camera 4 installed on the forklift fork frame 6, the operator can pick up and place goods more quickly and accurately, improving the safety and reliability of the three-way forklift stacking operation during high-position operation. It solves the problem that the forklift forks are at a relatively high position and the view is blocked by the forklift mast, oil circuit, etc., making it easier for the operator to grasp the relative position relationship between the forklift forks and the shelf, and significantly improving the stacking accuracy.

[0034] The above has described the preferred embodiments of the present utility model in detail, and it should not be considered as limiting the scope of implementation of the present utility model. All equivalent changes and improvements made according to the scope of the present utility model application should still fall within the patent coverage scope of the present utility model.
