[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] like Figures 1-4As shown in the figure, this utility model embodiment proposes a portable adjustable curbstone transport and installation vehicle, including:

[0022] Mounting rod 1 has two rotatable casters 2 at both ends. A connecting pipe 3 is fixedly connected to the mounting rod 1, and two adjustable handrails 7 are installed on the connecting pipe 3. The outer walls of both handrails 7 are fixed with rubber anti-slip sleeves, which makes it convenient for workers to hold and control the connecting pipe 3. An adjusting pipe 6 is slidably connected inside the connecting pipe 3. The handrails 7 are fixed to the adjusting pipe 6. Bolts are threaded onto the connecting pipe 3, and the bolts abut against the adjusting pipe 6 to position the adjusting pipe 6. Loosening the bolts adjusts the position of the adjusting pipe 6, which in turn adjusts the position of the handrails 7. This allows adjustment of the length of the connecting pipe 3 and the adjusting pipe 6 to accommodate different construction workers. This also adjusts the lever arm length, which can be adjusted according to the weight of the curbstone being clamped, in order to control the movement of the entire device.

[0023] In addition, a support leg 5 is fixedly connected to the bottom of the connecting pipe 3. When the device is placed horizontally, the support leg 5 is against the ground, so that the device can be flattened.

[0024] The mounting plate 9 is located above one side of the mounting rod 1. Multiple hanging holes 17 are provided on the mounting plate 9. The mounting rod 1 is equipped with a support frame 4. The connecting pipe 3 is equipped with a support pipe 21. The support pipe 21 is rotatably connected to the support frame 4. The bottom of the support pipe 21 is fixed with a support block. Both the support block and the support frame 4 are provided with through holes. The connecting shaft passes through the through holes to realize the rotatable installation of the two.

[0025] The other end of the support tube 21 is hinged to a hook 14, and a U-shaped block 13 is rotatably installed at the end of the support tube 21. The hook 14 is fixed to the bottom of the U-shaped block 13 by a chain. The hook 14 is hung in one of the hanging holes 17. The bottom of the hanging plate 9 is fixedly connected to a first horizontal arm 8. A second horizontal arm 10 is movably provided on the first horizontal arm 8. The first horizontal arm 8 and the second horizontal arm 10 slide against each other and can also be separated.

[0026] Both the first horizontal arm 8 and the second horizontal arm 10 have L-shaped clamps 11 fixed at opposite ends. Both the first horizontal arm 8 and the second horizontal arm 10 have multiple adjustment holes 12. Limiting bolts 15 are inserted through the adjustment holes 12 on the first horizontal arm 8 and the second horizontal arm 10. The limiting bolts 15 pass through different or the same adjustment holes 12 on the first horizontal arm 8 and the second horizontal arm 10. At this time, the first horizontal arm 8 and the second horizontal arm 10 are in different positions, resulting in an imbalance between the first horizontal arm 8 and the second horizontal arm 10. Therefore, it is necessary to hang the hooks 14 in different hanging holes 17 to ensure that the first horizontal arm 8 and the second horizontal arm 10 are in balance, so as to more stably clamp and move the curbstone.

[0027] As mentioned above, the limiting bolt 15 passes through different adjustment holes 12 on the first cross arm 8 and the second cross arm 10 to adjust the total length of the first cross arm 8 and the second cross arm 10, thereby controlling the distance between the two L-shaped clamps 11 and clamping curb stones of different lengths.

[0028] The limiting bolt 15 has a locking hole 16. A hexagonal ring 18 is slidably connected to the limiting bolt 15 and can abut against the second cross arm 10. A slidably positioned positioning pin 19 passes through the hexagonal ring 18. The positioning pin 19 is slidably connected in the locking hole 16 to fix the hexagonal ring 18 to the limiting bolt 15. A spring 20 is fixedly connected to the positioning pin 19. The spring 20 is fixedly connected to the hexagonal ring 18. In this way, the first cross arm 8 and the second cross arm 10 can be fixed together, making them difficult to separate. Because of the setting of the spring 20, the positioning pin 19 is not easy to disengage from the locking hole 16, thus ensuring that the limiting bolt 15 stably limits the first cross arm 8 and the second cross arm 10. There is no situation where the bolt and nut would loosen due to the use of bolts for limiting. Therefore, the first cross arm 8 and the second cross arm 10 are not easy to disengage, making it more convenient and stable to use.

[0029] When in use, move the entire device to the curbstone position so that the two L-shaped clamps 11 are on both sides of the curbstone. The construction worker presses down the handrail 7 to move the adjusting pipe 6, connecting pipe 3, and support pipe 21 downward. At this time, due to gravity, the two L-shaped clamps 11 rotate downward, that is, the first horizontal arm 8 and the second horizontal arm 10 rotate around the limit bolt 15 as the axis. The L-shaped clamps 11 abut against the curbstone. Due to the pulling force of the hook 14 on the scraper 9 and the first horizontal arm 8, the L-shaped clamps 11 at the end of the first horizontal arm 8 rotate downward and abut against the curbstone. Finally, the two L-shaped clamps 11 abut against the curbstone and can clamp the curbstone. Continuing to press the handrail 7 to move it down can make the curbstone leave the ground. Pushing the handrail 7 and using the moving wheels 2 can move and transfer the curbstone. It can be operated by a single person.

[0030] After pushing the curbstone to the designated location, slowly lift the handrail 7 and let it fall completely. Do not press down on the handrail 7 yet. Pull the handrail 7 backward. After the L-shaped clamp 11 is separated from the curbstone, press down the handrail 7 appropriately to adjust it to a comfortable height for the trolley to transport the next stone.

[0031] In summary, the position of the L-shaped clamp 11, which can be adjusted according to the length of the curbstone, can be used to accommodate curbstones of different sizes, reducing the difficulty of transporting curbstones. It also ensures smooth and convenient feeding, is easy to operate, can be operated by a single person, saves costs, has high safety, is highly practical, and can guarantee safety during transportation. It can also effectively prevent the first cross arm 8 and the second cross arm 10 from detaching.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
