Description

Technical Field

[0001] This utility model relates to the field of beam transport tools, and in particular to a beam transport system for F-beams. Background Technology

[0002] A special type of F-beam (such as...) has appeared on the market. Figure 1 As shown in the figure, it has been used in the construction of cross-sea bridges. Its unique design integrates pedestrian walkways, utility tunnels and green planting areas, which not only simplifies the on-site construction process, but also reduces the risk of pollution to the marine environment, achieving a unity of functionality and aesthetics.

[0003] Because the F-beam is an irregularly shaped beam with a huge weight (usually exceeding 400 tons), it needs to be prefabricated in sections at the beam fabrication yard and then transported to the construction site for installation. Existing methods of sectioning include... Figure 1 As shown, the structure is typically divided into three parts: A, B, and C. Parts A and B are roughly conventional "I"-shaped beams and can be transported to a standard beam transport vehicle using traditional wire rope hoisting. However, part C is an irregularly shaped block. To ensure its safe lifting, a special lifting device is required to support its bottom surface. The lifting device and part C are then transported to the construction site together without being removed (to facilitate the bridge erecting machine's direct lifting and erection of part C on-site). If a standard beam transport vehicle is used to transport part C, the lifting rod of the bottom lifting device will protrude downwards, preventing the part C and the lifting device from being placed stably on the transport vehicle, posing a significant risk of overturning. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing beam transport vehicles, which cannot stably place the C block on the beam transport vehicle when transporting F beams, resulting in a significant risk of overturning, and to provide a beam transport system for F beams.

[0005] In a first aspect, the present invention provides a beam transport system for F-beams, comprising: The beam transport vehicle has a support beam rotatably connected to its top surface, and a pad beam can be detachably installed on the top surface of the support beam. The top surface of the pad beam has a clearance groove, and the number, size, and position of the clearance groove match the hanging rod protruding from the bottom surface of block C of beam F.

[0006] The beam transport system for F-beams provided by this utility model, by setting up a pad beam and precisely matching the shape, size, and position of the clearance groove with the protruding lifting rod at the bottom of the C-block of the F-beam, allows the protruding lifting rod at the bottom of the C-block to enter the clearance groove during transportation, ensuring that the C-block beam can be placed stably and reliably on the top surface of the pad beam. This eliminates the risk of overturning during transportation, and eliminates the need to remove the C-block lifting equipment during transportation, thus improving overall construction efficiency. The support beam and the pad beam can be detached. When transporting other beams, such as I-beams and T-beams, the pad beam can be removed, which improves the utilization rate and versatility of the beam transport vehicle. The top of the beam transport vehicle is rotatably connected to a support beam, which allows the support beam to rotate at a certain angle during transportation, making it easier for the beam transport vehicle to turn and improving its passability.

[0007] Preferably, the support beam is rotatably connected to the beam transport vehicle via a rotating shaft.

[0008] With this structural design, when the C block is hoisted onto the beam transport vehicle, the support beam is connected to the beam transport vehicle's pivot, making it easier to adjust the position of the support beam and allowing the C block to be placed more stably on the beam transport vehicle's frame.

[0009] Preferably, two stops are installed on the top surface of the pad beam, and the positions of the stops are adjustable.

[0010] This structural design allows for the installation of adjustable stops on the top surface of the pad beam to accommodate bottom beams of different C-block sizes. During transportation, the stops also restrict the displacement of the bottom beams, thereby preventing the C-blocks from slipping and improving the safety of transporting the C-blocks.

[0011] Preferably, a plurality of bolt holes are formed on the top surface of the pad beam along the length direction of the pad beam, and the stop block is connected to the bolt holes by bolts.

[0012] With this structural design, several bolt holes are made along the length of the pad beam, allowing the stop blocks to be adjusted and positioned along the entire length of the pad beam in units of hole spacing. Operators can select the most suitable bolt holes to fix the stop blocks according to the bottom beam size of different C blocks.

[0013] Preferably, one end of the pad beam is hinged to a support rod, which is used to support the C block.

[0014] With this structural design, the center of gravity of block C is offset due to its irregular shape. The hinged support rod provides an adjustable additional support point. In use, the support rod can be passed through the hollow area at the bottom of block C (for weight reduction) and abut against the vertical wall of block C, further improving the stability of block C during transportation.

[0015] Preferably, a buffer pad is installed at the end of the support rod away from the pad beam.

[0016] With this structural design, the buffer pad can be made of elastic or flexible materials (such as rubber, polyurethane, etc.). It ensures that when the support rod contacts the C-block beam, it is not a rigid point contact, but a flexible surface contact. This effectively disperses the local pressure applied to the C-block by the support rod, prevents stress concentration in the contact area, and thus avoids structural damage to the C-block.

[0017] Preferably, the support rod includes a screw and a sleeve, the sleeve being threadedly connected to the screw, and the screw being hinged to the pad beam.

[0018] With this structural design, the sleeve and screw are threaded together. The effective length of the support rod can be adjusted by rotating the sleeve, ensuring that the support rod is accurately fitted to the predetermined support position of block C, providing stable support force and improving the stability of block C transportation.

[0019] Preferably, the sleeve is fixedly mounted with a handle, and the extension direction of the handle is perpendicular to the extension direction of the sleeve.

[0020] This structural design provides a large lever arm for the handle. Operators can easily adjust the length of the support rod by turning the handle, improving work efficiency.

[0021] Preferably, it further includes a plurality of wedge-shaped blocks, which are inserted between the top surface of the beam transport vehicle and the support beam.

[0022] With this structural design, the support beam does not require rotational freedom during long-distance straight transport on a smooth road surface. By inserting wedge blocks, the beam can be prevented from rotating accidentally, resisting the torsional moment caused by lateral wind force, lateral impact and minor road surface unevenness, and preventing unnecessary swaying of the beam during transportation.

[0023] Preferably, the pad beam is bolted to the support beam.

[0024] With this structural design, when transporting irregularly shaped C-blocks, the bolts securely fix the pad beam to the support beam; when transporting regular A or B beams or other standard beams, the pad beam can be quickly and easily removed, improving operational efficiency.

[0025] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention provides a beam transport system for F-beams. By setting up a pad beam and precisely matching the shape, size, and position of the clearance groove with the protruding lifting rod at the bottom of the C-block of the F-beam, the protruding lifting rod at the bottom of the C-block can enter the clearance groove during transportation, ensuring that the C-block beam can be placed stably and reliably on the top surface of the pad beam. This eliminates the risk of overturning during transportation, and eliminates the need to remove the C-block lifting equipment during transportation, thus improving overall construction efficiency.

[0034] Example 1 This embodiment provides a beam transport system for F-beams, mainly used for transportation. Figure 1 Block C of beam F in the middle.

[0035] like Figure 2 As shown, when transporting block C100, the lifting equipment and block C100 need to be transported together. Figure 2 The bottom of block C 100 is supported by the bottom beam 300 of the lifting device. The lower end of the lifting rod 200 passes through the bottom plate of block C 100 and is screwed to the bottom beam 300. Therefore, the lower end of the lifting rod 200 and the nut will protrude from the lower surface of the bottom beam 300, causing the bottom beam 300 to be unable to be stably placed on the top surface of the beam transport vehicle 1 frame.

[0036] Specifically, the beam transport system for beam F in this embodiment includes: The beam transport vehicle 1 has a supporting beam 2 rotatably connected to the top surface of its frame, such as... Figure 2 As shown, the support beam 2 and the beam transport vehicle 1 can be rotatably connected via a pivot 21. When the C block 100 is hoisted onto the beam transport vehicle 1, the support beam 2 is connected to the pivot 21 of the beam transport vehicle 1, which facilitates the adjustment of the position of the support beam 2, making it easier to place the C block 100 stably on the frame of the beam transport vehicle 1.

[0037] A pad beam 3 is detachably installed on the top surface of the support beam 2. Specifically, in this embodiment, the pad beam 3 and the support beam 2 can be connected by bolts. With this structural arrangement, when it is necessary to transport irregularly shaped C blocks 100, the bolts firmly fix the pad beam 3 to the support beam 2; when it is necessary to transport conventional A and B beam blocks or other standard beams, the pad beam 3 can be quickly and easily removed, improving work efficiency.

[0038] Among them, the top surface of the pad beam 3 has a clearance groove 31, the number, size, and position of which match the protruding hanger 200 on the bottom surface of block C of beam F. Specifically, as shown in... Figure 6 As shown, two clearance grooves 31 are provided on the top surface of the pad beam 3. The clearance grooves 31 can be rectangular grooves. The position of the clearance grooves 31 corresponds to the position of the lower end of the lifting rod 200 protruding from the lower surface of the bottom beam 300 of the lifting device, so that the lower end of the lifting rod 200 and the nut can enter the clearance grooves 31, and the bottom beam 300 can be placed stably on the upper surface of the pad beam 3.

[0039] The beam transport system for F-beam provided in this embodiment uses a pad beam 3 and precisely matches the shape, size, and position of the clearance groove 31 with the protruding lifting rod 200 at the bottom of block C 100 of F-beam. During transport, the protruding lifting rod 200 at the bottom of block C 100 can enter the clearance groove 31, ensuring that the beam body of block C 100 can land stably and reliably on the top surface of the pad beam 3, eliminating the risk of overturning during transport. The lifting equipment for block C 100 does not need to be removed during transport, thus improving overall construction efficiency.

[0040] The support beam 2 and the pad beam 3 are detachably connected. When transporting other beams, such as I-beams and T-beams, the pad beam 3 can be removed, which improves the utilization rate and versatility of the beam transport vehicle 1.

[0041] The top surface of the beam transport vehicle 1 is rotatably connected to the support beam 2. During transportation, the support beam 2 is allowed to rotate at a certain angle, which facilitates the turning of the beam transport vehicle 1 and improves the passability of the beam transport vehicle 1.

[0042] Furthermore, such as Figure 2 , Figure 5 As shown, two stops 4 are installed on the top surface of the pad beam 3, and the positions of the stops 4 are adjustable. This structural design allows for the installation of adjustable stops 4 on the top surface of the pad beam 3 to accommodate the bottom beam 300 of different sized C-blocks 100. During transportation, the stops 4 also limit the displacement of the bottom beam 300, thus preventing slippage of the C-block 100 and improving the safety of the C-block 100 during transport. In this embodiment, the stops 4 can be welded from I-beams or angle steel.

[0043] Specifically, such as Figure 5 , Figure 6 As shown, the top surface of the pad beam 3 is along the length direction of the pad beam 3 (e.g., Figure 6Several bolt holes 32 are made in the left and right directions, and the stop block 4 is connected to the bolt holes 32 by bolts. With this structure, several bolt holes 32 are made along the length of the pad beam 3, which allows the stop block 4 to be adjusted and positioned in units of hole spacing along the entire length of the pad beam 3. The operator can select the most suitable bolt holes 32 to fix the stop block 4 according to the size of the bottom beam 300 at the bottom of different C blocks 100.

[0044] Furthermore, such as Figure 3 , Figure 4 As shown, the beam transport system for the F-beam provided in this embodiment also includes several wedge blocks 6. Specifically, the number of wedge blocks 6 can be four, six, or eight, and the wedge blocks 6 can be arranged on both sides of the support beam 2. The wedge tips of the wedge blocks 6 can be inserted between the top surface of the beam transport vehicle 1 and the support beam 2. With this structural arrangement, the wedge blocks 6 can be removed when the support beam 2 needs to be rotated. When carrying out long-distance straight transport on a smooth road surface, the support beam 2 does not require rotational freedom. By inserting the wedge blocks 6, accidental rotation of the support beam 2 can be prevented, resisting lateral wind forces, lateral impacts, and torsional moments caused by minor road surface irregularities, thus preventing unnecessary swaying of the beam during transport.

[0045] Example 2 Based on Example 1, the beam transport system for beam F provided in this example has a support rod 5 hinged to one end of the pad beam 3. The support rod 5 is used to support block C 100. Specifically, as shown... Figure 2 As shown, support rod 5 can be installed at the right end of pad beam 3. Furthermore, support rod 5 can be installed on the side of C block 100 where the center of gravity is offset, and C block 100 will be prefabricated at its cantilevered end (specifically, for example...). Figure 1 At the right-middle end, the cantilevered end of block C100 (mainly serving as a pedestrian walkway, primarily bearing relatively small pedestrian loads) is designed with a hollowed-out shape to further reduce the overall weight of beam F. One end of the support rod 5 is hinged to the pad beam 3, and the other end can pass through the hollowed-out part of block C100, supporting it on the vertical wall of block C100.

[0046] With this structural arrangement, the center of gravity of block C 100 is offset due to its irregular shape. The hinged support rod 5 provides an adjustable additional support point. In use, the support rod 5 can be passed through the hollow area at the bottom of block C 100 (for weight reduction) and abut against the vertical wall of block C 100, further improving the stability of block C 100 during transportation.

[0047] Furthermore, such as Figure 7As shown, a buffer pad 51 is installed at the end of the support rod 5 away from the pad beam 3. The buffer pad 51 can be made of elastic or flexible materials (such as rubber, polyurethane, etc.). It can ensure that when the support rod 5 contacts the beam body of block C 100, it is not a hard point contact, but a flexible surface contact. This effectively disperses the local pressure applied to block C 100 by the support rod 5, prevents stress concentration in the contact area, and thus avoids structural damage to block C 100.

[0048] Furthermore, the support rod 5 includes a screw 52 and a sleeve 53. The internal thread of the sleeve 53 is connected to the external thread of the screw 52, ​​and the screw 52 is hinged to the pad beam 3. With this structural arrangement, the sleeve 53 is threadedly connected to the screw 52, ​​and the effective length of the support rod 5 can be adjusted by rotating the sleeve 53. This ensures that the support rod 5 is accurately fitted to the predetermined support position of block C 100, providing stable support force and improving the stability of block C 100 during transportation.

[0049] Furthermore, a handle 531 is fixedly mounted on the sleeve 53, with the extension direction of the handle 531 perpendicular to the extension direction of the sleeve 53. This structural arrangement provides a larger lever arm for the handle 531. The operator can easily adjust the length of the support rod 5 by rotating the handle 531, improving work efficiency.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
