Technical Field
[0001] This utility model relates to the field of beam transport vehicle technology, and in particular to an adjustable beam transport vehicle. Background Technology
[0002] In the construction of highway and railway bridges, precast beams need to be transported from the beam fabrication yard to the bridge erection site. During the transportation process, beam transport vehicles are used. These vehicles are special engineering vehicles used to transport large precast concrete beams and play a key role in large-scale infrastructure projects such as bridge construction and railway engineering.
[0003] In the construction of highway and railway bridges, beams of different sizes are required. However, traditional beam transport vehicles can only transport beams of fixed sizes. When other sizes of beams need to be transported, the lack of a suitable limiting mechanism makes it easy for the beams to fall off during transportation, which is extremely dangerous.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0026] Reference Figure 1-5 An adjustable beam transport vehicle includes a beam transport vehicle body 1, an end limiting plate 4, and a side limiting plate 5. A strip groove 11 is provided at one end of the top of the beam transport vehicle body 1, and an end mounting groove 13 is provided at one end of the strip groove 11. A motor 2 is fixedly installed in the end mounting groove 13. The motor 2 drives a lead screw 21, which is located in the strip groove 11. Grooves 12 are provided at both ends of the top of the beam transport vehicle body 1. Side mounting grooves 14 are provided at the outer ends of the two grooves 12. A motor 3 is fixedly installed in the side mounting groove 14. The motor 3 drives a lead screw 31, which is located in the groove 12.
[0027] The end limiting plate 4 has a first nut pair 41 at its bottom, which is threaded onto the lead screw 21. The side limiting plate 5 has a second nut pair 51 at its bottom, which is threaded onto the lead screw 31. This allows the motor 2 to drive the end limiting plate 4 to move, and the motor 3 to drive the side limiting plate 5 to move.
[0028] Meanwhile, bearings 6 are embedded in both sides of the inner wall of the strip groove 11, and sliding grooves 111 are opened on the other two sides of the inner wall of the strip groove 11.
[0029] Furthermore, both ends of the lead screw 21 are connected to two bearings 6 respectively. When the lead screw 21 rotates, the main body 1 of the beam transport vehicle will not rotate under the action of the bearings 6.
[0030] Meanwhile, both ends of the first nut assembly 41 are provided with sliders 411, which slide within the groove 111. Slider 411 makes the movement of the end limiting plate 4 more stable.
[0031] Meanwhile, bearings 7 are embedded in both sides of the inner wall of the groove 12, and sliding grooves 121 are opened on both other sides of the inner wall of the groove 12.
[0032] Furthermore, both ends of the lead screw 31 are connected to two bearings 7 respectively. When the lead screw 31 rotates, the main body 1 of the beam transport vehicle will not rotate under the action of the bearings 7.
[0033] Meanwhile, sliders 511 are provided on both sides of the second nut assembly 51. Slider 511 slides within the groove 121, making the movement of the side limiting plate 5 more stable.
[0034] Furthermore, two fixing rings 52 are provided on the back side of the side limiting plate 5. A fixing rope 10 is fixedly connected inside the fixing ring 52. The other end of the fixing rope 10 is fixedly connected to the fixing ring 52 of the other side limiting plate 5. The fixing rope 10 binds the beam to the beam transport vehicle body 1, which facilitates the safe transport of the beam transport vehicle body 1.
[0035] Meanwhile, threaded holes 9 are provided on the top of both the first nut assembly 41 and the second nut assembly 51.
[0036] Furthermore, threaded posts 8 are provided at the bottom of both the end limiting plate 4 and the side limiting plate 5. The threaded posts 8 are threaded into the threaded holes 9. Rotating the end limiting plate 4 and the side limiting plate 5 facilitates the replacement of the end limiting plate 4 and the side limiting plate 5.
[0037] In this embodiment, the beam is transported onto the beam transport vehicle body 1 via external equipment. Then, two motors 2 at one end of the two beam transport vehicle bodies 1 are simultaneously started. Motors 2 drive lead screws 21 to rotate, causing the first nut assembly 41 to move under the rotation of the lead screws 21. This causes the two end limiting plates 4 of the two beam transport vehicle bodies 1 to move towards each other, making close contact with both ends of the beam. The end limiting plates 4 limit the beam. Then, two motors 3 of the two beam transport vehicle bodies 1 are started. Drive the second lead screw 31 to rotate, and the second nut pair 51 moves towards the beam under the rotation of the second lead screw 31, so that the two side limiting plates 5 are in close contact with the two ends of the beam. The side limiting plates 5 play a limiting role for the beam. Then, one end of the fixing rope 10 is fixedly connected to the fixing ring 52. Then, the fixing rope 10 is wrapped around the beam and tightened, and the other end of the fixing rope 10 is fixedly connected to the fixing ring 52 of the opposite side limiting plate 5. At this time, the fixing rope 10 firmly binds the beam to the main body 1 of the beam transport vehicle, which facilitates the safe transport of the beam.
[0038] At the same time, rotate the end limiting plate 4 and the side limiting plate 5 to remove the end limiting plate 4 and the side limiting plate 5 from the first nut pair 41 and the second nut pair 51, and replace them with end limiting plates 4 and the side limiting plate 5 that conform to the shape of the beam.
[0039] In this invention, the positions of the end limiting plate 4 and the side limiting plate 5 are adjusted according to the size of the beam. The end limiting plate 4 and the side limiting plate 5 limit the beam, enabling the beam transport vehicle to safely transport beams of different sizes, thus providing greater flexibility.
[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
