[0003] Existing patent CN221629418U discloses an auxiliary support device for a paver, including a mounting plate. A fixed plate is fixedly mounted on the front side of the mounting plate, and a drive motor is fixedly mounted on the right side of the fixed plate. The output end of the drive motor extends through the fixed plate to the left side of the fixed plate and is fixedly mounted with a screw. A movable plate is threadedly connected to the surface of the screw. A first hinge seat is fixedly mounted on the front side of the movable plate. A first robotic arm is hinged inside the first hinge seat. A rotating shaft is fixedly mounted inside the first robotic arm. A second robotic arm is rotatably connected to the surface of the rotating shaft. A caster wheel is provided at the bottom of the second robotic arm. A lifting assembly is provided at the rear side of the second robotic arm, and a support block is provided at the rear side of the second robotic arm via the lifting assembly.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 4This utility model provides a technical solution: an auxiliary support device for a paver, including a frame 1, a first robotic arm 11, and a second robotic arm 12. The frame 1 is equipped with an adjustment component, and the second robotic arm 12 is equipped with a support component. The adjustment component includes a sliding opening 21 within the frame 1, adjustment seats 22 respectively located on both sides of the sliding opening 21, a through opening 23 at the top of the sliding opening 21, a groove 24 at the top of the adjustment seat 22, a sliding rod 25 within the groove 24, a spring 26 sleeved on the outside of the sliding rod 25, a plurality of arc-shaped grooves 27 evenly arranged on both sides of the top of the through opening 23, and a circular plate 28 fixedly connected to the outside of the sliding rod 25. The circular plate 28 and the arc-shaped grooves 27... The sliding rod 25 is slidably connected to the sliding groove 24, and the adjusting seat 22 is slidably connected to the sliding opening 21. The first robotic arm 11 is hinged to the adjusting seat 22, and the second robotic arm 12 is hinged to the first robotic arm 11. Vertical movement of the sliding rod 25 can deform the spring 26, simultaneously causing the circular plate 28 to disengage from the arc-shaped groove 27, releasing the adjusting seat 22. Pushing the adjusting seat 22 allows for position adjustment. The spring 26 can reset the circular plate 28, causing it to re-enter other arc-shaped grooves 27, thus fixing the adjusted adjusting seat 22 and preventing its movement. Each adjusting seat 22 can be adjusted individually. A support groove 41 is provided at the bottom of the sliding opening 21 for adjustment. A support block 42 is fixedly connected to the top of the adjustment seat 22. The support block 42 is slidably connected to the support groove 41. The support block 42 can move synchronously with the adjustment seat 22, which can guide the adjustment seat 22 and improve the stability of the adjustment seat 22. An anti-rotation groove 51 is opened at the bottom of the slide rod 25. An anti-rotation plate 52 is fixedly connected to the bottom of the groove 24. The anti-rotation plate 52 is slidably connected to the anti-rotation groove 51. The vertical movement of the slide rod 25 can make the anti-rotation plate 52 slide in the anti-rotation groove 51. The anti-rotation groove 51 can restrict the slide rod 25 and prevent the slide rod 25 from rotating, thereby preventing the spring 26 from rotating and being damaged. A connecting plate 61 is fixedly connected to the top of the slide rod 25. A pull ring is fixedly connected to the top of the connecting plate 61. 62. The pull ring 62 facilitates the movement of the connecting plate 61, which in turn facilitates the vertical movement of the slide rod 25, and facilitates the release of the adjusting seat 22. A first hydraulic rod 81 is provided between the adjusting seat 22 and the first robotic arm 11, and a second hydraulic rod 82 is provided between the first robotic arm 11 and the second robotic arm 12. The two ends of the first hydraulic rod 81 are hinged to the adjusting seat 22 and the first robotic arm 11, respectively, and the two ends of the second hydraulic rod 82 are hinged to the first robotic arm 11 and the second robotic arm 12, respectively. The operation of the first hydraulic rod 81 can drive the first robotic arm 11 to rotate to both sides, and the second hydraulic push rod can push the second robotic arm 12 to rotate around the hinge point of the first robotic arm 11 and the second robotic arm 12.

[0026] Please see Figure 1 , Figure 2 , Figure 5 as well as Figure 6 The supporting components include a mounting port 31 on one side of the second robotic arm 12, a motor 32 fixedly connected to the top of the mounting port 31, a screw 33 fixedly connected to the bottom of the motor 32, a movable plate 34 connected to the outside of the screw 33, a first support rod 35 fixedly connected to both sides of the bottom of the movable plate 34, and a first support 36 fixedly connected to the bottom of the first support rod 35. The screw 33 is screwed to the movable plate 34 and rotatably connected to the inner wall of the mounting port 31. The motor 32 can drive the screw 33 to rotate, which allows the movable plate 34 to move vertically, thereby driving the first support rod 35 and the first support 36 to move vertically, causing the first support 36 to move down and contact the ground, thus providing stable support. Extension plates 71 are fixedly connected to the four sides of the movable plate 34. A second support rod 72 is fixedly connected to the bottom of the extension plate 71, and a second support 73 is fixedly connected to the bottom of the second support rod 72. The second support rod 72 and the second support 73 can increase the support points, thereby further improving the support stability.

[0027] Working principle: During operation, when adjustment of the adjusting seat 22 is required, the pull ring 62 can be pulled. The movement of the pull ring 62 causes the connecting plate 61 to move upward, which in turn causes the slide rod 25 to move upward. The upward movement of the slide rod 25 causes the spring 26 to deform, simultaneously causing the circular plate 28 to move upward. The movement of the circular plate 28 disengages from the arc groove 27, allowing the adjusting seat 22 to be moved to the appropriate position, aligning the circular plate 28 with the arc groove 27. Releasing the pull ring 62 causes the spring 26 to return to its original position, which in turn causes the circular plate 28 to return to its original position, allowing the circular plate 28 to be inserted into the arc groove 27. The adjusted seat 22 can be fixed to prevent it from moving. When support is needed, the motor 32 starts and drives the screw 33 to rotate. The rotation of the screw 33 drives the moving plate 34 to move down. The moving plate 34 moves down and drives the extension plate 71 to move down, which in turn causes the first support rod 35 and the second support rod 72 to move down, which in turn causes the first support 36 and the second support 73 to move down, thus enabling multi-point support and improving support stability. The above is the working process of the entire device. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
