Abstract
Description
Technical Field
[0001] This utility model relates to the field of AGV hooks, and more specifically, to a traction-type AGV automatic hook device. Background Technology
[0002] AGVs are equipped with automated guidance systems, which ensure that the system can automatically travel along a predetermined route without manual guidance, transporting goods or materials from the starting point to the destination. However, AGVs are not suitable for carrying too much cargo. Compared to AGVs, flatbed trucks can carry more cargo. Therefore, in current cargo handling processes, AGVs are usually hooked to flatbed trucks, and then the AGVs tow the flatbed trucks for movement.
[0003] The existing hook devices do not have additional protective structures at the connection point during use. As a result, the connection point frequently collides with the AGV vehicle and the flatbed vehicle during movement, causing the hook to shake and resulting in poor stability of the hook device. This poses a safety hazard of the connection point falling off, which is an urgent problem to be solved by those skilled in the art. Utility Model Content

[0030] Reference Figures 1-5 An automatic AGV towing hook device includes an AGV transport vehicle connector 1, a housing 2, a fixing plate 3, and a flatbed connector 4. The housing 2 is fixedly connected to the outer wall of the AGV transport vehicle connector 1, the fixing plate 3 is fixedly connected to the outer wall of the housing 2, the flatbed connector 4 is disposed outside the fixing plate 3, the outer wall of the fixing plate 3 is provided with a towing component 5, and the outer wall of the fixing plate 3 is provided with a stabilizing component 6.
[0031] The towing assembly 5 includes a hydraulic push rod 501, a connecting plate 502, a fixing member 503, a plug rod 504, and a retaining ring 505. The hydraulic push rod 501 is fixedly connected to the outer wall of the housing 2. The connecting plate 502 is disposed on the outer wall of the fixing plate 3. The output end of the hydraulic push rod 501 is fixedly connected to the bottom of the connecting plate 502. The outer wall of the connecting plate 502 is slidably connected to the outer wall of the fixing plate 3. When the hydraulic push rod 501 operates, it can push the connecting plate 502 to slide on the outer wall of the fixing plate 3. The fixing member 503 is fixedly connected to the outer wall of the connecting plate 502. The plug rod 504 is installed on the fixing plate. The outer wall of the fixed plate 3 is through which the insertion rod 504 passes through the fixing member 503 and extends to the outer wall of the fixing member 503. The insertion rod 504 is fixedly connected to the fixing member 503. The retaining ring 505 is fixedly connected to the outer wall of the trolley connector 4. The insertion rod 504 passes through the fixing plate 3 and the retaining ring 505, and is slidably connected to the inner wall of the fixed plate 3 and the inner wall of the retaining ring 505. When the fixing member 503 moves the insertion rod 504 under the action of the connecting plate 502, the insertion rod 504 can slide inside the fixing plate 3 and be fixed to the trolley connector 4 by the retaining ring 505.
[0032] By installing a hydraulic push rod 501 and a plug rod 504 on the surface of the AGV transport vehicle connector 1, and placing the flatbed connector 4 on the outer wall of the fixed plate 3, the operation of the hydraulic push rod 501 can be controlled to drive the plug rod 504 to move through the connecting plate 502 and the fixing member 503. This allows the plug rod 504 to pass through the retaining ring 505 and extend to the outside of the fixed plate 3, thereby completing the fixation of the flatbed connector 4. This solves the problem that existing hook devices cannot guarantee the stability of the connection and are prone to falling off during use.

The inner wall of the extension 601 is slidably connected to the outer wall of the insert rod 504. The outer wall of the extension 601 has a groove 6011. When the retaining ring 505 is placed on the surface of the first fixing plate 3 by the movable trolley connector 4, the extension 601 will pass through the first fixing plate 3 and extend to the bottom of the first fixing plate 3, and be fixed by the insert rod 504. The second fixing plate 602 is installed at the bottom of the first fixing plate 3 and is connected to the first fixing plate 3 by bolts. The outer ring 603 is fixed... The bottom of the fixed plate 602 is fixedly connected to the outer wall of the outer ring 603. The outer wall of the outer ring 603 is fixedly connected to the protruding ring 6031, which is engaged with the groove 6011. While the fixed plate 602 is fixed by bolts, the protruding ring 6031 will be engaged with the inside of the groove 6011, further ensuring the stability of the trolley connector 4. The fixed plate 604 is fixedly connected to the outer wall of the outer shell 2. The spring 605 is fixedly connected to the outer wall of the fixed plate 604. The bent plate 606 is fixedly connected to the side of the spring 605 away from the fixed plate 604. The top of the bent plate 606 abuts against the bottom of the extension 601. The bottom of the bent plate 606 is provided with bolts and is fixed to the extension 601 by bolts. The bent plate 606 can be fixedly installed on the bottom of the extension 601 by bolts.
[0034] By installing an outer ring 603 and a bent plate 606 at the bottom of the fixed plate 3, the flatbed truck connector 4 is installed on the outer wall of the fixed plate 3, causing the extension 601 to move to the bottom of the fixed plate 3. Then, the outer ring 603 is moved so that the convex ring 6031 is inserted into the groove 6011 and fixed with bolts. The bent plate 606 is moved so that the bent plate 606 moves to the bottom of the extension 601. Then, the bent plate 606 is connected to the extension 601 with bolts, thereby further ensuring the stable connection between the flatbed truck connector 4 and the AGV transport vehicle connector 1.
[0035] The working principle of this traction-type AGV automatic hook device is as follows: By controlling the operation of the hydraulic push rod 501, the output end of the hydraulic push rod 501 drives the insertion rod 504 to move through the connecting plate 502 and the fixing member 503. After the insertion rod 504 is moved, the trolley connecting member 4 is moved by sliding, so that the extension member 601 passes through the fixing plate 3 and extends to the bottom of the fixing plate 3. At the same time, the bottom of the retaining ring 505 abuts against the outer wall of the fixing plate 3. Then, the hydraulic push rod 501 is controlled to reset, so that the insertion rod 504 passes through the retaining ring 505, thus completing the fixation of the trolley connecting member 4.
