DETAILED DESCRIPTION

[0030] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0031] See also Figure 1-11The utility model provides a transport vehicle for placing curbstones, including a crossbar 1 and two sets of clamps 6. A rotating column 11 is fixedly connected to the lower surface of the crossbar 1 and a position one-third away from the front side. A column 2 is connected below the crossbar 1. A rotating hole 21 is opened on the upper surface of the column 2. The rotating column 11 is rotatably connected to the inside of the rotating hole 21. The lower end of the column 2 is fixedly connected to a crossbeam 22. The upper surface of the crossbeam 22 is symmetrically fixedly connected to a diagonal brace 23 on both sides of the column 2. The left and right ends of the crossbeam 22 are rotatably connected to wheels 24. The left and right sides of the crossbar 1 and a position one-third away from the front side are fixedly connected to the crossbeam 22. The positions of the two sets of fixed seats 3 are fixedly connected with the fixed seats 3, and the front sides of the two groups of fixed seats 3 and the ends away from the cross bar 1 are fixedly connected with the slide rail seats 4. The interior of the slide rail seats 4 is provided with a slide groove 41, and the lower surface of the slide groove 41 is penetrated by a through groove 42. The interior of the slide groove 41 is slidably connected with a moving block 51, and the lower surface of the moving block 51 is rotatably connected with a hook 5. The two sets of clamps 6 are movably hoisted under the hook 5 on the corresponding side respectively. The interior of the slide rail seat 4 is connected with a transmission assembly 7 for driving the moving block 51 to slide, and the left and right sides of the rear end of the cross bar 1 are connected with movable handles 8 for controlling the operation of the transmission assembly 7.

[0032] The utility model provides two sets of clamps 6. During the process of transporting the curbstone, the two sets of clamps 6 respectively clamp the two ends of the curbstone, which can reduce the shaking of the curbstone during transportation, thereby increasing the stability of transportation. Secondly, when placing the curbstone, the operator used to operate the transport vehicle can control the two sets of clamps 6 to move along the slide rail seat 4 through the two sets of movable handles 8 on the left and right, thereby completing the positioning and fine-tuning of the position of the curbstone (the specific operation method is: rotating the movable handle 8, the movable handle 8 drives the moving block 51 to move along the slide 41 through the transmission component 7, and the moving block 51 drives the clamp 6 to move through the hook 5). This operation method only requires one person to operate, and the other person can be located in front of the curbstone placement position to direct, which effectively saves the manpower required for adjustment. At the same time, the operator does not need to directly contact the curbstone when placing the curbstone, which reduces the risk of collision and improves operational safety.

[0033] Specifically, the crossbar 1 is in a rotating structure with respect to the upright post 2. In actual transportation, the operator can change the position of the curbstone by rotating the crossbar 1 without changing the orientation of the wheels 24.

[0034] It should be noted that the clamp 6 adopts a lifting ring clamp, which is a conventional clamp 6 used for transporting curbstones in the prior art, and its structure will not be described in detail herein.

[0035] Furthermore, a solid block 31 is provided in the middle of the fixed seat 3, and a hollow cavity 32 is provided inside the fixed seat 3 and on both sides of the solid block 31. The transmission assembly 7 includes a threaded rod 71, a short shaft rod 73 and a long shaft rod 76. The threaded rod 71 is rotatably connected to the inside of the slide rail seat 4, and the moving block 51 is threadedly sleeved on the outside of the threaded rod 71. The rear end of the threaded rod 71 passes through the slide rail seat 4 and extends to the inside of the hollow cavity 32. The rear end of the threaded rod 71 is fixedly connected to a bevel gear 1 72, and the interior of the solid block 31 is rotatably connected to a short shaft rod 73. The end of the short shaft rod 73 away from the cross bar 1 is fixedly connected to a bevel gear 2 74, and the bevel gear 2 74 is meshed with the bevel gear 1 72. The end of the short shaft rod 73 close to the cross bar 1 is fixedly connected to a bevel gear 3 75. There are multiple groups of ear plates 12 fixedly connected on both the left and right sides. The ear plates 12 are internally rotatably connected with a long shaft rod 76. The front end of the long shaft rod 76 is fixedly connected with a bevel gear four 77. The bevel gear four 77 is meshed with the bevel gear three 75. The left and right sides of the rear end of the cross bar 1 are fixedly connected with the mounting seat 13. The long shaft rod 76 extends through and extends into the interior of the mounting seat 13. The rear end of the long shaft rod 76 is fixedly connected with a bevel gear five 78. The side of the bevel gear five 78 away from the cross bar 1 is meshed with a bevel gear six 79. The interior of the bevel gear six 79 is fixedly connected with a connecting shaft rod 710. The connecting shaft rod 710 extends through and extends to the outside of the side of the mounting seat 13 away from the cross bar 1, and the connecting shaft rod 710 is rotatably connected to the mounting seat 13. The movable handle 8 is fixedly sleeved on the outside of the connecting shaft rod 710.

[0036] Specifically, by rotating the movable handle 8 forward and backward, the movable block 51 can slide back and forth inside the slide groove 41, allowing the operator to manipulate the movement of the clamp 6 through the movable handle 8 to achieve precise adjustment of the clamp 6, thereby adjusting the position of the curbstone. Specific operation method: Rotate the movable handle 8, the movable handle 8 drives the bevel gear 6 79 to rotate through the connecting shaft 710, and the bevel gear 6 79 in turn drives the bevel gear 5 78 engaged therewith to rotate, and the bevel gear 5 78 drives the bevel gear 4 77 to rotate through the long shaft 76, and the bevel gear 4 77 in turn drives the bevel gear 3 75 engaged therewith to rotate, and the bevel gear 3 75 drives the bevel gear 2 74 to rotate through the short shaft 73, and the bevel gear 2 74 in turn drives the bevel gear 1 72 engaged therewith to rotate, and the bevel gear 1 72 drives the threaded rod 71 to rotate, at which point the movable block 51 undergoes a displacement change. If the moving direction of the movable block 51 needs to be changed, it is only necessary to change the rotation direction of the movable handle 8.

[0037] Furthermore, a fixed sleeve 9 is rotatably connected to the outside of the connecting shaft 710 and located between the mounting seat 13 and the movable handle 8. The fixed sleeve 9 is fixed to the mounting seat 13, and a fixed handle 91 is fixedly provided on the outside of the fixed sleeve 9.

[0038] Specifically, the fixing sleeve 9 forms a fixed structure with the crossbar 1 through the mounting seat 13. The operator can operate the transport vehicle by holding the fixing handle 91, making the operation more stable.

[0039] Furthermore, a threaded buckle 7101 is provided on the outer wall of the connecting shaft 710 and located between the fixed sleeve 9 and the movable handle 8. The outer threaded sleeve of the threaded buckle 7101 is provided with a locking nut 92 for limiting the rotation of the movable handle 8.

[0040] Specifically, during the transport of a curbstone, the stability of the curbstone held by the clamp 6 needs to be ensured. The operator can tighten the locking nut 92 until it abuts against one side of the fixed sleeve 9. This prevents the movable handle 8 from rotating, thereby preventing the movement of the clamp 6. This effectively locks the position of the clamp 6, ensuring the stability and safety of the curbstone during transport.

[0041] Furthermore, an annular groove 25 is provided on the outer wall of the column 2, and a movable ring 26 is rotatably connected inside the annular groove 25. The movable ring 26 is fixedly connected with diagonal struts 27 on all four sides. The upper ends of the two groups of diagonal struts 27 on the front and rear sides are fixed to the cross bar 1, and the upper ends of the two groups of diagonal struts 27 on the left and right sides are fixed to the two groups of fixed seats 3 respectively.

[0042] Specifically, when the crossbar 1 and the column 2 rotate relative to each other, the crossbar 1 can drive the four sets of diagonal braces 27 and the movable ring 26 to rotate together. The diagonal braces 27 and the movable ring 26 provide additional support for the crossbar 1 and the fixed base 3, making the structure more solid, while not affecting the relative rotation between the crossbar 1 and the column 2.

[0043] Furthermore, guide grooves 43 are provided on both the left and right sides of the slide groove 41 , and rollers 52 are rotatably connected to both the left and right sides of the moving block 51 , and the rollers 52 are slidably connected inside the guide grooves 43 .

[0044] Specifically, when the displacement of the moving block 51 changes, the roller 52 is driven to slide inside the guide groove 43 , so that the moving block 51 moves more smoothly and the adjustment is smoother.

[0045] Furthermore, multiple groups of connecting rods 44 are fixedly connected between the cross bar 1 and the slide rail seat 4, multiple groups of vertical rods 45 are fixedly connected to the lower surface of the cross bar 1, and three diagonal braces 46 are fixedly connected between the connecting rods 44 and the vertical rods 45.

[0046] Specifically, the connecting rod 44, the vertical rod 45 and the diagonal support 46 form a stable triangular structure, which can provide additional support for the slide rail seat 4, enhance the stability of the connection between the cross bar 1 and the slide rail seat 4, and ensure the firmness and durability of the overall structure.

[0047] Furthermore, a fixing rod 10 is fixedly connected to the rear side of the lower surface of the crossbar 1 , and a footrest ring 101 is fixedly connected to the lower end of the fixing rod 10 .

[0048] Specifically, by adding the pedal ring 101, the operator can use the pedal ring 101 to assist in exerting force when lifting the curbstone, thereby reducing the force exerted by both hands and making the operation easier and more efficient.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
