Description

Technical Field

[0001] This utility model relates to the field of beam transport vehicle technology, and in particular to a beam transport and fastening device and a beam transport vehicle. Background Technology

[0002] A girder transporter is a specialized engineering vehicle used to transport large precast concrete components (such as bridge beams, box girders, and T-beams). It is widely used in highway, railway, bridge, and building construction projects, playing a crucial role, especially when transporting heavy precast components over long distances or in complex terrain. During bridge girder replacement, girder transporters are used to load and transport old or new beams. A crane is used to accurately place the beam onto the designated position on the transporter, ensuring the beam's center of gravity is aligned with the transporter's centerline for balance. The transporter then drives the old or new beam to the designated location.

[0003] However, existing beam transport vehicles cannot reliably secure the beams during transport. On the one hand, the beam transport vehicle will vibrate due to road conditions during transport, which can easily cause the beams to fall off the vehicle. On the other hand, the beam transport vehicle will generate centripetal force when passing through curves, which can easily cause the beams to overturn laterally, resulting in low safety.

[0023] Because existing beam transport vehicles cannot reliably secure the beams during transport, the beams are prone to falling off the vehicle due to vibrations caused by road conditions. Furthermore, the beam transport vehicles generate centripetal forces when passing through curves, which can easily cause the beams to overturn laterally, resulting in low safety.

[0024] Therefore, this embodiment provides a beam transport fastening device, which is installed on a beam transport vehicle and can fasten the beam placed on the beam transport vehicle to prevent the beam from falling off the vehicle or overturning, thereby improving the safety of transportation.

[0025] Please see Figure 1 , Figure 2 and Figure 3 The beam transport and fastening device provided in this embodiment includes an adjustment component 1 and a clamping component 2. The adjustment component 1 is installed on the beam transport vehicle 10 and connected to the clamping component 2. The beam 20 can be clamped by the adjustment component 1 and the clamping component 2, and the beam 20 is fastened to the beam transport vehicle 10.

[0026] Specifically, please refer to Figure 1 Two adjustment components 1 are provided, which are arranged opposite each other and installed on both sides of the beam transport vehicle 10 in the width direction, with the beam 20 placed between the two adjustment components 1. Further, please refer to... Figure 2 and Figure 3 The adjustment component 1 includes a sleeve 11, a first connector 12, and a second connector 13. The sleeve 11 has reverse internal threads at both ends. One end of the first connector 12 and one end of the second connector 13 are respectively screwed to the two ends of the sleeve 11. The other end of the second connector 13 is hinged to the beam transport vehicle 10. By screwing the sleeve 11, the distance between the first connector 12 and the second connector 13 extending into the sleeve 11 is simultaneously extended or shortened, thereby adjusting the overall height of the adjustment component 1 to adapt to beams 20 of different specifications.

[0027] Specifically, please refer to Figure 2 The clamping assembly 2 includes a pressure plate 21. Both ends of the pressure plate 21 are connected to the other ends of two first connecting members 12 located on either side of the beam transport vehicle 10 in the width direction. Tightening the sleeve 11 adjusts the distance between the first connecting member 12 and the second connecting member 13 extending into the sleeve 11, thereby adjusting the height of the pressure plate 21 so that it can be firmly pressed against the top of the beam body 20. Preferably, the pressure plate 21 is arranged along the width direction of the beam body 20.

[0028] This embodiment, by setting two adjustment components 1, can not only press the pressure plate 21 tightly onto the top of the beam 20, thereby securing the beam 20 to the beam transport vehicle 10, but also block the beam 20 when the beam transport vehicle 10 generates centripetal force, providing lateral force to the beam 20 to prevent the beam 20 from overturning.

[0029] For example, please refer to Figure 2The first connector 12 provided in this embodiment includes a plug rod 121, a connecting rod 122, and a connecting cylinder 123. The outer wall of the plug rod 121 is provided with external threads, so that it can be inserted into and screwed to the inner wall of the sleeve 11. One end of the connecting rod 122 is connected to the end of the plug rod 121, and the other end is fixed to the connecting cylinder 123. The connecting cylinder 123 is used to connect the pressure plate 21. Preferably, the end of the pressure plate 21 is provided with at least two through holes at intervals along its length direction. The connecting cylinder 123 passes through the corresponding through holes. The end of the pressure plate 21 is inserted into the connecting cylinder 123, and bolts are used to pass through the openings on the connecting cylinder 123 and the corresponding through holes on the pressure plate 21 and fix them, thereby connecting the pressure plate 21 to the connecting cylinder 123.

[0030] With the above settings, the connection between the pressure plate 21 and the connecting cylinder 123 can be realized, and the length of the pressure plate 21 extending into the connecting cylinder 123 can be adjusted, improving the adaptability to the beam 20 and providing greater flexibility.

[0031] In this embodiment, the connecting rod 122 is hinged to the insert rod 121, thereby allowing the angle between the connecting rod 122 and the insert rod 121 to be freely adjusted according to the specifications of the beam 20, further improving flexibility. For example, a first hinge plate (not shown in the figure) is fixed to the end of the insert rod 121, and the first hinge plate is vertically arranged. A second hinge plate (not shown in the figure) is fixed to one end of the connecting rod 122, and the second hinge plate is vertically arranged. The first hinge plate and the second hinge plate are fitted together, and a first hinge hole is formed in the first hinge plate. A corresponding second hinge hole is formed in the second hinge plate. A pin is passed through the first hinge hole and the second hinge hole and fixed, thereby achieving the hinge between the connecting rod 122 and the insert rod 121. Preferably, the first hinge plate is welded to the end of the insert rod 121, and the second hinge plate is welded to the end of the connecting rod 122.

[0032] Furthermore, the clamping assembly 2 also includes several pushing units, which are installed on the pressure plate 21 and used to push the top of the beam 20 to further tighten the beam 20.

[0033] Preferably, a plurality of pushing units are installed at intervals along the length of the pressure plate 21, so that the plurality of pushing units apply force evenly to the beam 20 along the width direction.

[0034] Specifically, please refer to Figure 2 The push unit includes a push screw 22 and a nut 23. The nut 23 is fixed to the top of the pressure plate 21 and several through holes are opened in the pressure plate 21. The through holes correspond one-to-one with the nut 23. The push screw 22 is screwed to the nut 23 and one end of the push screw 22 passes through the pressure plate 21. By further screwing the push screw 22, one end of the push screw 22 is pressed against the top of the beam 20.

[0035] Optionally, the push unit also includes a push plate, which is fixed to one end of the push screw 22. The push plate is used to press against the top of the beam 20 to increase the contact area with the beam 20 and optimize the fastening effect on the beam 20.

[0036] The beam transport and fastening device provided in this embodiment also includes a first transverse component 3 and a second transverse component 4. Both the first transverse component 3 and the second transverse component 4 are used to provide transverse support force for the beam 20 to further prevent the beam 20 from overturning under the action of centripetal force.

[0037] Specifically, please refer to Figure 1 Two first transverse components 3 are provided, and the two first transverse components 3 provide transverse and opposite forces to the beam 20 to balance the transverse forces on the beam 20. For example, the two first transverse components 3 are symmetrically arranged and respectively installed on both sides of the beam transport vehicle 10 in the width direction. Please refer to [reference needed]. Figure 2 The first transverse component 3 includes a first screw block 31 and a horizontally arranged first adjusting screw 32. The first screw block 31 is fixed to the beam transport vehicle 10, and the first adjusting screw 32 is screwed to the first screw block 31. Tightening the first adjusting screw 32 causes one end to abut against the side wall of the beam 20, providing transverse support force for the beam 20.

[0038] With the above configuration, one end of each of the two first adjusting screws 32 can abut against the two side walls in the width direction of the beam 20, thereby providing a balanced lateral support force for the beam 20 and preventing the beam 20 from overturning under the action of centripetal force.

[0039] Because a through groove 201 is provided in the middle region of the bottom of the beam 20 along its length, the second transverse component 4 applies a balanced transverse force to the groove wall of the through groove 201, further stabilizing the beam 20. For example, please refer to... Figure 1 Two second transverse components 4 are provided, which provide lateral and opposite forces to the beam 20 to balance the lateral forces on the beam 20. The two second transverse components 4 are symmetrically arranged and installed in the middle area of ​​the beam transport vehicle 10 so as to apply force to the through groove 201 in the middle area of ​​the bottom of the beam 20 after loading the beam 20. Please refer to [link to relevant documentation]. Figure 2 The second transverse component 4 includes a second screw block 41 and a horizontally arranged second adjusting screw 42. The second screw block 41 is fixed to the beam transport vehicle 10, and the second adjusting screw 42 is screwed to the second screw block 41. Tightening the second adjusting screw 42 causes one end to abut against the groove wall of the through groove 201, providing transverse support force for the beam 20.

[0040] With the above settings, one end of each of the two second adjusting screws 42 can abut against the two groove walls in the width direction of the through groove 201, further strengthening the lateral support of the beam 20 and preventing the beam 20 from overturning under the action of centripetal force.

[0041] Preferably, a reinforcing plate is fixed to both the end of the first adjusting screw 32 near the beam 20 and the end of the second adjusting screw 42 near the beam 20. The reinforcing plate is used to press against the beam 20 to increase the contact area with the beam 20 and optimize the support effect on the beam 20.

[0042] The beam transport and fastening device provided in this embodiment also includes a support component 5, which is used to provide support force for the variable cross-section load position of the beam 20, and further prevent the beam 20 from overturning.

[0043] Specifically, please refer to Figure 1 There are two support components 5, which are arranged opposite each other and installed on both sides of the beam transport vehicle 10 in the width direction. Please refer to [link / reference]. Figure 2 The support component 5 includes a connecting pipe 51 and a telescopic member 52. One end of the connecting pipe 51 is hinged to the beam transport vehicle 10, and the telescopic member 52 is inserted into and screwed to the other end of the connecting pipe 51.

[0044] Preferably, please refer to Figure 2 The ends of the two connecting pipes 51 furthest from the telescopic member 52 are both hinged to the beam transport vehicle 10. More preferably, the ends of the two connecting pipes 51 furthest from the telescopic member 52 are respectively hinged to the tops of two first threaded blocks 31 mounted on the beam transport vehicle 10 to improve overall integrity. For example, the connecting pipes 52 are hinged to the first threaded blocks 31 via hinge shafts.

[0045] With the above settings, the two expansion joints 52 are screwed on to adjust the length of the expansion joints 52 extending out of the connecting pipe 51, so that the ends of the two expansion joints 52 away from the connecting pipe 51 can abut against the variable cross-section load-bearing positions on both sides of the beam 20 in the width direction.

[0046] This embodiment also provides a beam transport vehicle 10, which is equipped with a plurality of the above-mentioned beam transport fastening devices. The plurality of beam transport fastening devices are installed at intervals along the length direction of the beam transport vehicle 10. The plurality of beam transport fastening devices act on different areas along the length direction of the beam 20 to ensure that the beam 20 is fastened to the beam transport vehicle 10 and to prevent the beam 20 from falling off the vehicle or overturning during transportation.

[0047] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
