Description

Technical Field

[0001] This utility model relates to the field of beam transport vehicle technology, specifically a tire beam transport vehicle for single and double-line beam transport. Background Technology

[0002] Beam transport vehicles are large-scale special transport equipment designed specifically for bridge engineering. Their core function is to safely and efficiently transport precast concrete beams. They are commonly used in bridge construction scenarios such as highways, railways, and high-speed railways. Their design needs to be adapted to the weight and size of the beams. They usually adopt a multi-axle, multi-wheel structure to distribute the load and avoid damage to the road surface or beams. Equipped with hydraulic suspension and steering systems, they can achieve precise positioning and steering to meet the transportation needs of complex construction sites (such as between bridge prefabrication yards and beam erection points).

[0003] In the construction of bridges for highways, railways, and high-speed railways, when prefabricated girder bridges need to be transferred from the prefabrication yard to the girder erection site, the girder transport vehicle undertakes the core transportation task. When transporting and handling girder bridges, the girder transport vehicle needs to use a double-track transport method. However, most double-track girder transport vehicles currently face problems such as the girder blocking the vehicle body when turning, height differences in the ground environment, and suspension buffer support during actual girder transport. It is still difficult to achieve a relatively stable girder transport.

[0004] Meanwhile, in the beam loading stage of bridge construction, the current common practice is to "position first, then fix". First, the precast beam is placed on the bearing platform of the beam transport vehicle using hoisting equipment such as gantry cranes and cranes. Then, the workers use high-strength straps to tie and fix the beam at key stress points on both sides and ends. However, this fixing method is time-consuming and labor-intensive in actual operation, and there is also a certain degree of danger in the positioning process (i.e., when the beam is still suspended in the air).

[0005] Based on this, the present invention provides a tire beam transport vehicle with single and double lines to solve the above problems. Utility Model Content

[0006] In view of the above situation and to overcome the defects of the prior art, this utility model provides a tire beam transport vehicle with single and double lines.

[0030] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figures 1 to 6 The detailed description of the embodiments will make this clear. All references to the following embodiments are made with reference to the accompanying drawings.

[0031] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings.

[0032] This utility model relates to a tire-mounted beam transport vehicle with single and double lines, comprising a tractor unit 1, a main beam transport frame 2 connected to the tractor unit 1, and a secondary beam transport frame 6 connected to the main beam transport frame 2. There are two tractor units 1, two main beam transport frames 2, and two secondary beam transport frames 6, enabling the transport of large beams and improving transport efficiency. Three sets of connecting frames 8, composed of welded square tubing, are provided between the two main beam transport frames 2 and between the two secondary beam transport frames 6. A traction frame 14 is provided between the connecting frames 8 at the rear of the main beam transport frame 2 and the front of the secondary beam transport frame 6. The structure is a triangular configuration composed of multiple square tubes. Each of the two main beam-carrying frames 2 and the two auxiliary beam-carrying frames 6 has a beam-supporting trolley pallet 3. Each beam-supporting trolley pallet 3 is rotatably connected to a beam-supporting trolley rotating plate 4. Two symmetrically distributed overlapping seats 37 are fixedly installed above each beam-supporting trolley rotating plate 4. Multiple connecting hinge frames 9 are fixedly installed on one side of each of the two main beam-carrying frames 2 and the two auxiliary beam-carrying frames 6. Each set of connecting frames 8 is hinged within four connecting hinge frames 9. The hinge frames 9 and connecting frames 8 cooperate to achieve a staggered connection between the two main beam-carrying frames 2 and the two auxiliary beam-carrying frames 6, adapting to different ground heights during actual transportation. A rear overlapping seat is fixedly installed above the overlapping seats 37 on the auxiliary beam-carrying frame 6. Frame 7, with a pulley frame 17 fixedly installed on the rear connecting frame 7, and a support pulley 18 rotatably connected inside the pulley frame 17, the support pulley 18 can support the main beam, and in conjunction with the external towing system, move to the foremost front of the main beam transport frame 2. Two front suspension hydraulic systems are provided between the two main beam transport frames 2 and their corresponding beam-supporting trolley pallets 3. The two front suspension hydraulic systems are symmetrically arranged between one beam-supporting trolley pallet 3 and the two main beam transport frames 2, and are hydraulically connected in series. Two rear suspension hydraulic systems are provided between the two sub-frames 6 and their corresponding beam-supporting trolley pallets 3. The two rear suspension hydraulic systems are symmetrically arranged between one beam-supporting trolley pallet 3 and the two sub-frames 6, and are independent hydraulic systems. The system consists of a front suspension hydraulic system forming a stable suspension structure, and a rear suspension hydraulic system forming two independent and stable suspension structures. These, along with four connecting seats 37, create a four-point support, three-point load-bearing structure, ensuring the stability of the beam during transport. A support frame 15 is fixedly installed on one side of the front connecting frame 8 on the beam transport subframe 6. A secondary articulation frame 16 is fixedly installed on one side of the support frame 15. The traction frame 14 is hinged within the secondary articulation frame 16. A rear articulation frame 11 is fixedly installed on one side of the traction frame 14. A front articulation frame 10 is fixedly installed on one side of the rear connecting frame 8 on the beam transport main frame 2. Both the rear articulation frame 11 and the front articulation frame 10 are rotatably connected to a connecting block 13 via a fixed pin 12. A pull ring 34 is rotatably connected above the fixed pin 12.By setting up a front hinge frame 10, a rear hinge frame 11, and an auxiliary hinge frame 16, the connection of the transport structure with staggered front and rear heights can be accommodated, allowing the transport structure to adapt to environments with different ground heights.

[0033] In this embodiment, firstly, two main beam transport frames 2 and two auxiliary beam transport frames 6 are hinged together by connecting hinge frames 9 and connecting frames 8. Then, the main beam transport frame 2 is moved by the tractor head 1, so that the front hinge frame 10 on the connecting frame 8 side of the main beam transport frame 2 and the rear hinge frame 11 on the connecting frame 8 side of the auxiliary beam transport frame 6 are close together. Then, the connecting block 13 is placed in the front hinge frame 10 and the rear hinge frame 11, and the connecting block 13 is connected to the front hinge frame 10 and the rear hinge frame 11 by means of the fixing pin 12, thereby realizing the connection between the main beam transport frame 2 and the auxiliary beam transport frame 6.

[0034] Then, the main beam is placed above the rotating plate 4 of the beam-carrying trolley on the beam-carrying subframe 6, and with the help of the external towing system and the support pulley 18, the main beam is pulled towards the tractor head 1 until it is close to the tractor head 1. During transportation, when the tractor head 1 turns, it drives the main beam-carrying frame 2 to turn. The rotation between the beam-carrying trolley pallet 3 and the beam-carrying trolley rotating plate 4 can prevent the main beam from getting stuck on the beam-carrying subframe 6 and ensure the stability of turning.

[0035] When the ground is uneven in height from front to back or from side to side, the hinge between the connecting hinge frame 9 and the connecting frame 8 is used to compensate for the height misalignment between the left and right sides. At the same time, the auxiliary hinge frame 16 is used to compensate for the height misalignment between the front and back.

[0036] When the transport equipment vibrates during transport, it works in conjunction with a front suspension hydraulic system, two rear suspension hydraulic systems, and four supporting overlap seats 37 to form a four-point support and three-point force-bearing state, which stabilizes and buffers the vibration of the transported beam and ensures the safety of the transported beam.

[0037] As an example, a bottom beam 36 is fixedly installed at the rear of each of the two beam transport subframes 6. A hydraulic rod 35 is provided inside the bottom beam 36, and a foot 30 is fixedly installed at the bottom end of the output shaft of the hydraulic rod 35.

[0038] In this embodiment, when loading and unloading the main beam, the hydraulic rod 35 can be controlled to work, driving the foot 30 to descend, thereby providing fixed support for the overall transport structure.

[0039] As an example, two symmetrically distributed overlap limiting frames 21 are fixedly installed inside the rear overlap frame 7. The overlap limiting frame 21 is a metal block with one side inclined. Each overlap limiting frame 21 has two symmetrically distributed limiting grooves 22. Each limiting groove 22 is slidably connected to a limiting slider 23. The limiting groove 22 is an inclined groove. The top of every two adjacent limiting sliders 23 is fixedly installed with the same adjusting block 24. The top of each adjusting block 24 is fixedly installed with a positioning plate 20. The positioning plate 20 is a T-shaped metal frame. A side lifting plate 27 is fixedly installed on one side of each of the two adjusting blocks 24. A main lifting frame 25 is slidably connected to the surface of each side lifting plate 27. A threaded rod 28 is threadedly connected to the main lifting frame 25. An overlap plate 19 is fixedly installed on the top of the threaded rod 28. The threaded screw 28 is used to adjust the height of the overlapping plate 19. The height of the overlapping plate 19 is related to the moving distance of the positioning plate 20. The surface of the overlapping plate 19 is provided with a pry bar groove 31. The surface of the threaded screw 28 is threaded with a fixing nut 29, which is used to lock the threaded screw 28. The main lifting frame 25 is provided with a support slide groove 26. The side lifting plate 27 is slidably connected in the support slide groove 26. The rear overlapping frame 7 is fixedly installed with a connecting rod 32. The surface of the connecting rod 32 is slidably connected with a lifting sleeve 33. A return spring is provided between the lower part of the lifting sleeve 33 and the rear overlapping frame 7. The lifting sleeve 33 is fixedly installed on one side of the main lifting frame 25. The front overlapping frame 5 is fixedly installed above the overlapping seat 37 on the main beam transport frame 2. The front overlapping frame 5 is used to support the overlapping of the main beam.

[0040] In this embodiment, before placing the main beam, a pry bar can be inserted into the pry bar slot 31 according to the width of the main beam. Then, the overlapping plate 19 is rotated, which drives the threaded rod 28 to rotate, thereby causing the threaded rod 28 and the overlapping plate 19 to rise and fall, adjusting the height of the overlapping plate 19. After adjusting the height of the overlapping plate 19, the fixing nut 29 is rotated to press against the main lifting frame 25, locking the threaded rod 28 and the overlapping plate 19, thus fixing the height of the overlapping plate 19. The main beam is placed on the lap plate 19, and gravity presses down the lap plate 19 and the main lifting frame 25, thereby pressing down the side lifting plate 27 and the adjusting block 24. When the adjusting block 24 descends, the limiting slider 23 slides downward and inward in the limiting slide groove 22. During the inward sliding of the limiting slider 23, it can drive the adjusting block 24 and the positioning plate 20 to slide inward as well. When the beam presses on the rear lap frame 7, the positioning plate 20 stops sliding inward. At this time, the positioning plate 20, which has been adjusted to a certain position, can provide limiting support for the beam.

[0041] Working principle:

[0042] S1. First, the two main beam transport frames 2 and the two auxiliary beam transport frames 6 are hinged to the connecting frame 8 through the connecting hinge frame 9. Then, the front hinge frame 10 on the connecting frame 8 side of the main beam transport frame 2 is brought close to the rear hinge frame 11 on the connecting frame 8 side of the auxiliary beam transport frame 6. The connecting block 13 is placed into the front hinge frame 10 and the rear hinge frame 11 and connected with the fixing pin 12 to realize the connection between the main beam transport frame 2 and the auxiliary beam transport frame 6. At the same time, the auxiliary hinge frame 16 ensures the adaptability of the front and rear connection between the two.

[0043] S2. Then, place the main beam on the beam-carrying trolley rotating plate 4 on the beam transport subframe 6. With the help of the external towing system and the support pulley 18 in the pulley frame 17 on the rear overlap frame 7, pull the main beam close to the tractor head 1. The front overlap frame 5 cooperates with the rear overlap frame 7 to overlap and support the main beam. Before placing, according to the width of the main beam, use a pry bar to insert into the pry bar slot 31 of the overlap plate 19 and rotate the threaded screw 28 to adjust its height. Then lock it with the fixing nut 29. After the main beam is placed, press down on the overlap plate 19 and the main lifting frame 25, so that the side lifting plate 27 drives the adjusting block 24 to descend. The limiting slider 23 slides down and moves inward in the limiting groove 22 of the overlap limiting frame 21, driving the positioning plate 20 to limit the main beam.

[0044] S3. During transportation, when the tractor head 1 turns, the beam-supporting trolley pallet 3 and the beam-supporting trolley rotating plate 4 rotate relative to each other to prevent the main beam from getting stuck on the beam-carrying subframe 6. When the ground is uneven in height in the front and back or left and right, the connection between the connecting hinge frame 9 and the connecting frame 8 realizes the left and right height misalignment compensation, and the sub-hinged frame 16 realizes the front and back height misalignment compensation.

[0045] S4. When vibration occurs, the front suspension hydraulic system connected in series between the two main beam transport frames 2 and the corresponding beam support trolley pallet 3, and the independent rear suspension hydraulic system between the two sub-frames 6 and the corresponding beam support trolley pallet 3, together with the four overlapping seats 37, form a four-point support and three-point force state to buffer the vibration.

[0046] S5. During loading and unloading, the hydraulic rod 35 inside the bottom beam 36 behind the beam transport subframe 6 drives the foot 30 to descend, thus fixing and supporting the overall structure.

[0047] This utility model has the following beneficial technical effects.

[0048] 1. This utility model, by setting up a double-set traction tractor head 1, a beam transport main frame 2, and a beam transport sub-frame 6, can adapt to large-size beams and solve the problem of insufficient load-bearing capacity in traditional systems. The connecting hinge frame 9, the connecting frame 8, the front hinge frame 10, the rear hinge frame 11, and the sub-hinge frame 16 respectively compensate for the height difference between the left and right sides and the front and rear sides of the ground. The beam support trolley tray 3 and the rotating plate 4 ensure turning stability. The front suspension hydraulic system, the rear suspension hydraulic system, and the overlapping seat 37 buffer vibration. The fixed pin shaft 12 and the hydraulic rod 35 improve the stability of operation and support.

[0049] 2. This utility model automatically adapts to beams of different widths by setting up the linkage between the overlapping limit frame 21 (limiting slide groove 22), the limiting slider 23, the adjusting block 24 and the positioning plate 20. The pry bar is inserted into the pry bar slot 31 to rotate the overlapping plate 19, which drives the threaded screw 28 to adjust the height. The fixing nut 29 is locked, making the operation convenient. The connecting rod 32, the lifting sleeve 33 and the return spring help the structure to reset and reduce wear. The front overlapping frame 5 and the rear overlapping frame 7 form a double support to distribute the weight.

[0050] 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 the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
