Technical Field

[0001] The present invention relates to the field of heavy-load unmanned AGV, and in particular to a heavy-load unmanned AGV with a protective function. Background Art

[0002] A heavy-duty unmanned AGV is a load-bearing AGV unmanned transport vehicle that uses visual recognition navigation technology and accurate positioning. It is used to transport heavy objects.

DETAILED DESCRIPTION

[0022] The following is combined with Figure 1-5 This application is described in further detail.

[0023] Example 1

[0024] See also Figures 1 to 3 , which is the first embodiment of the present invention, and this embodiment provides a technical solution: a heavy-duty unmanned AGV with automatic identification function, comprising

[0025] AGV trolley body 1, wheels 11 installed on both sides of the AGV trolley body 1, a pallet 2 fixed on the top surface of the AGV trolley body 1, a support column 4 fixed on the front surface of the AGV trolley body 1, and a visual recognition probe 5 installed on the top of the support column 4. An identification head is also provided at the bottom center of the AGV trolley body 1 for identifying the route on the bottom surface (this part of the identification function is a prior art, and the specific details can be referred to the existing patent with publication number CN215157996U, which will not be repeated here); considering that in order to facilitate unloading of heavy objects An adjustable enclosure mechanism is provided at the edges of both sides of the pallet 2, and the adjustable enclosure mechanism includes a limit baffle 31, a base strip 32 and an adjustment assembly 33. The limit baffle 31 movably passes through the edge of the pallet 2, and the top of the limit baffle 31 extends out of the top surface of the pallet 2, which can effectively block and limit the goods placed on the top of the pallet 2 to prevent the goods from falling from both sides when the pallet 2 is transporting the goods, and the bottom end of the limit baffle 31 is welded and fixed with a base strip 32 relative to the bottom of the pallet 2, and the adjustment structure 33 is arranged between the pallet 2 and the limit baffle 31.

[0026] Wherein, a strip-shaped through hole is provided at both side edges of the support plate 2 for the limit baffle 31 to pass through.

[0027] The cam 334 is a spring loaded part which is adapted to move the cam 335 in a direction of rotation with the spring 336 engaged to move the cam 336 in a direction of rotation.

[0028] The later operator can push the shift block 331 to make the connecting block 337 move sideways with the inner slider 335 and gradually compress the spring 334, so that the end of the limit rod 336 moves out of the limit slot 332, and the limit on the limit baffle 31 can be released. At this time, the limit baffle 31 can be slid up and down for adaptive height adjustment. When it is adjusted to a suitable height, release the shift block 331, the spring 334 will push the inner slider 335 back to reset, and make the limit rod 336 rebound and get stuck in the limit slot 332 at other positions, so that the limit baffle 31 can be limited again, completing the height adjustment of the limit baffle 31.

[0029] Among them, a cylindrical groove is opened on one side surface of the inner sliding block 335, one end of the spring 334 is embedded in the cylindrical groove, and the other end of the spring 334 is fixed on the inner wall of the inner sliding groove 333 to ensure the installation stability of the spring 334.

[0030] Among them, a pop-up hole is opened between the inner slide groove 333 and the strip-shaped through hole, and the pop-up hole corresponds to the limiting card rod 336 to facilitate the smooth pop-up and subsequent activities of the end of the limiting card rod 336.

[0031] Example 2

[0032] See also Figures 1 to 5 , which is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but differs in that it further includes a base sleeve 6 fixed on the rear surface of the visual recognition probe 5, the base sleeve 6 is slidably sleeved on the support column 4, and a clamping limit assembly 7 is provided on the base sleeve 6, a sleeve hole 61 is opened through the surface of the base sleeve 6, and the sleeve hole 61 is adapted to the support column 4, so that the base sleeve 6 can be smoothly slid on the surface of the support column 4 for subsequent height adjustment of the visual recognition probe 5.

[0033] The clamping and limiting structure 7 includes a rectangular inner groove 72 opened on the inner wall of one side of the sleeve hole 61, an inner plate 74 installed in the rectangular inner groove 72, and two connecting rods 73 fixed on the surface of one side of the inner plate 74. The ends of the two connecting rods 73 pass through the outside of the base sleeve 6 and are fixed with a pull plate 71. A clamping pad 75 is glued and fixed to the other side surface of the inner plate 74, and the clamping pad 75 is in tight contact with the support column 4 to achieve the clamping and limiting of the base sleeve 6 during daily use and ensure the installation stability of the visual recognition probe 5. The clamping and limiting structure 7 also includes two reset springs 76 arranged between the pull plate 71 and the base sleeve 6.

[0034] If you want to adjust the height of the visual recognition probe 5 laterally, you only need to pull the pull plate 71 to stretch the two reset springs 76 and move the inner plate 74 and the pressing pad 75 to the side, so that the pressing pad 75 is no longer pressed against the support column 4, and the limit on the base sleeve 6 can be released. At this time, the base sleeve 6 can be slid up and down on the surface of the support column 4 to change the height of the visual recognition probe 5. When the visual recognition probe 5 is adjusted to a suitable height, release the pull plate 71, and the two reset springs 76 will pull the pull plate 71 back, and make the connecting rod 73 rebound with the inner plate 74 and the pressing pad 75, and finally make the pressing pad 75 press against the surface of the support column 4, so as to achieve the pressing limit of the base sleeve 6 and the visual recognition probe 5, thereby completing the height adjustment of the visual recognition probe 5.

[0035] Among them, two tension spring installation grooves are opened on the side of the base sleeve 6, one end of the reset tension spring 76 is fixed in the tension spring installation groove, and the other end of the reset tension spring 76 is fixedly connected to the pull plate 71.

[0036] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
