[0033] It also includes a load-bearing plate 7, which is arranged on the top of the vehicle body 1 to support the box beam.

[0034] Embodiment 2

[0035] Reference Figure 1-Figure 5 , the present invention provides a new technical solution based on the first embodiment:

[0036] In the present invention, a positioning groove 18 is provided on the top of the vehicle body 1, and a turntable 5 is rotatably connected in the positioning groove 18. A guide column 6 is fixedly connected to the surface of the turntable 5. The load-bearing plate 7 is slidably sleeved on the circumference of the guide column 6. Two first hydraulic cylinders 19 are fixedly installed on the top of the turntable 5. One end of the hydraulic rod of the first hydraulic cylinder 19 is fixed to the bottom of the load-bearing plate 7. When the ground has a slope, the first hydraulic cylinder 19 is started, and the first hydraulic cylinder 19 can drive the load-bearing plate 7 to move, thereby adjusting the level of the box beam and improving the stability of transportation.

[0037] In particular, a plurality of fixing sleeves 22 are fixedly connected to the bottom of the positioning groove 18 , and the tops of the fixing sleeves 22 are rotatably connected to balls 23 supporting the turntable 5 , so that the stability of the rotation of the turntable 5 is increased by the balls 23 .

[0038] It should be noted that side plates 20 are fixedly connected to both sides of the load-bearing plate 7, and multiple wedge blocks 31 are welded between the bottom of the side plates 20 and the load-bearing plate 7. The side plates 20 are welded to the load-bearing plate 7 to facilitate the transportation of the box girder.

[0039] In the present invention, two guiding telescopic rods 21 are fixedly connected to the surface of the turntable 5 , and the tops of the two telescopic rods 21 are respectively fixed to the two side plates 20 , so that the telescopic rods 21 are used to further increase the stability of the load-bearing plate 7 .

[0040] In particular, the bottom of the vehicle body 1 is also provided with an adjustment mechanism 24 for adjusting the position of the vehicle body 1. The adjustment mechanism 24 includes a mounting groove 25. The mounting groove 25 is opened at the bottom of the vehicle body 1. A second guide rail 26 is provided at the bottom of the mounting groove 25. A second slider 27 is slidably connected in the second guide rail 26. Two mounting seats 29 are fixedly connected to the surface of the second slider 27. A second hydraulic cylinder 28 is rotatably connected between the mounting seats 29 and the top of the mounting groove 25. The two second hydraulic cylinders 28 are opposite and inclined. A third hydraulic cylinder 30 is fixedly connected to the inner wall of one side of the second guide rail 26. One end of the hydraulic rod of the third hydraulic cylinder 30 is fixed to the second slider 27. When the second hydraulic cylinder 28 is started, the second hydraulic cylinder 28 drives the second guide rail 26 to move downward so that the second guide rail 26 contacts the ground.

[0041] It should be noted that two vertical plates are arranged at both ends of the load-bearing plate 7, and a through fixing hole 9 is opened on one side of the two vertical plates. The fixing hole 9 is convenient for tying the box girder with steel wire ropes.

[0042] In the present invention, a sealing ring 8 is fixedly connected to the circumference of the turntable 5 . The sealing ring 8 is located above the vehicle body 1 . The sealing ring 8 reduces the entry of impurities into the interior of the turntable 5 .

[0043] In particular, an extension frame 4 is welded to one side of the vehicle body 1, and the extension frame 4 is a working station for operators.

[0044] The beneficial effects of the intelligent transportation device for prefabricated box beam transportation of the present invention are as follows:

[0045] Protection mechanism design: The protection mechanism 3 at the front end of the device is composed of a slide bar 10, a first guide rail 11, a first slider 13 and a baffle 15, etc., which can effectively prevent animals or pedestrians from being crushed during transportation. The baffle 15 is tilted, which can not only guide the collision object to the side of the vehicle body 1, but also buffer it through the slide bar 10 and the first spring 12 when it is hit, avoiding direct impact, greatly improving the safety of transportation.

[0046] Roller design: The roller 16 design at the bottom of the baffle 15 makes the baffle 15 move more smoothly, while also maintaining the contact between the baffle 15 and the ground, avoiding a large gap at the bottom, and further improving the safety of use.

[0047] Design of load-bearing plate and turntable: The load-bearing plate 7 is slidably sleeved on the circumference of the guide column 6 and is connected to the turntable 5 through the first hydraulic cylinder 19. When the ground is sloped, the first hydraulic cylinder 19 is started to drive the load-bearing plate 7 to move, thereby adjusting the level of the box beam and improving the stability of transportation.

[0048] Telescopic rod and ball design: The telescopic rod 21 on the surface of the turntable 5 is connected to the side plate 20, which increases the stability of the load-bearing plate 7; the ball 23 design at the bottom of the turntable 5 increases the rotation stability of the turntable 5, further improving the overall transportation stability.

[0049] Multiple spring design: The top and bottom of the first slider 13 are respectively fixedly connected with the second spring 14 and the third spring 17 with different lengths. This design enables the baffle 15 to be buffered by the springs when it is hit in different directions, thereby improving the stability and safety of the device.

[0050] Adjustment mechanism design: The adjustment mechanism 24 at the bottom of the device can adjust the angle of the vehicle body 1 through the cooperation of the second hydraulic cylinder 28 and the third hydraulic cylinder 30. This can assist the vehicle body 1 to pass smoothly when the turning radius of the intersection is small and the vehicle body 1 is difficult to turn, greatly improving the adaptability of the device.

[0051] Sealing ring design: The sealing ring 8 design on the circumference of the turntable 5 can reduce the entry of impurities into the turntable 5, keep the turntable clean and lubricated, increase the service life and reliability of the turntable, and further improve the adaptability of the device.

[0052] Fixing hole design: The fixing holes 9 opened on the vertical plates at both ends of the load-bearing plate 7 facilitate the use of wire ropes to tie the box girder, thereby improving the convenience of loading and unloading.

[0053] Extension frame design: The extension frame 4 design on one side of the vehicle body 1 provides a work station for the operator, facilitates the operation and monitoring of the operator, and improves the convenience of the device.

[0054] Working principle: When in use, at least two transport devices are used in combination to hoist the box beam onto the load-bearing plate 7, and then the box beam is transferred and transported by the vehicle body 1. During transportation, the baffle 15 is set in front of the forward direction of the driving wheel 2, and the forward direction of the driving wheel 2 is blocked by the baffle 15 to avoid crushing animals. At the same time, the baffle 15 is tilted. When animals or pedestrians hit the baffle 15, the baffle 15 can also guide them to the side of the vehicle body 1, further improving the safety of use. When the baffle 15 is collided, the baffle 15 and the slide bar 10 can also move to the side close to the driving wheel 2, and are buffered by the first spring 12 to avoid collision, further improving the safety of the vehicle body 1 in transporting the box beam. When the road surface is uneven, the baffle 15 can also move up and down Movement, thereby maintaining the contact between the roller 16 and the ground, maintaining the height of the baffle 15, avoiding a large gap at the bottom of the baffle 15, and further improving the safety of use. When the ground is sloped, the first hydraulic cylinder 19 is started, and the first hydraulic cylinder 19 can drive the load-bearing plate 7 to move, thereby adjusting the level of the box girder and improving the stability of transportation. When the turning radius of the intersection is small and the vehicle body 1 is difficult to turn, the second hydraulic cylinder 28 is started, and the second hydraulic cylinder 28 drives the second guide rail 26 to move downward, so that the second guide rail 26 contacts the ground, and the hydraulic rod of the second hydraulic cylinder 28 continues to extend, thereby lifting one end of the vehicle body 1, and then the third hydraulic cylinder 30 is started, and the third hydraulic cylinder 30 pushes the second slider 27 to adjust the angle of the vehicle body 1, thereby assisting the vehicle body 1 to pass through the intersection.

[0055] However, as is well known to those skilled in the art, the working principles and wiring methods of the first hydraulic cylinder 19, the second hydraulic cylinder 28 and the third hydraulic cylinder 30 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any selections according to their needs or convenience.

[0056] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
