Description

Technical Field

[0001] This invention relates to the field of bridge construction technology, specifically to a device and control method for preventing overturning during long-distance transportation of ultra-long I-beams. Background Technology

[0002] The main span of the North Ring Road Bridge in Section No. QL11 of the Western Land-Sea New Corridor (Pinglu) Canal Overpass Project is 372m. The main bridge deck consists of grid beams arranged in 43m sections. Except for the end crossbeams which use box sections, the rest are I-beam sections. The entire bridge has a total of 153 main / secondary crossbeams (I-beams), all of which are extra-long components of 43m. The bridge required long-distance truck transport from the factory to the bridge site assembly yard, a total of 38 kilometers, along winding, bumpy, and poorly maintained roads with many curves and small turning radii.

[0003] The conventional method for preventing overturning of I-beams (grid beams) during long-distance transport of bridge decks is through hydraulic jack support or direct spot welding restraint. Hydraulic jack support involves installing jacks on the transport vehicle. During use, the I-beam is placed on the transport vehicle, and jacks located on opposite sides of the I-beam provide support. For example, CN216659726U discloses a novel beam support transport vehicle. The transport vehicle has a support beam mounted on its upper end. Both ends of the support beam are hinged to support rods. A support mechanism is provided on one side of each support rod, and a mounting frame is fixed to one end of each support rod. Jacks are installed within the mounting frame, and a pad is fixed to the piston rod end of each jack. Mounting blocks are fixed to both sides of the upper end of the support beam. A hand-operated hoist is mounted on the upper end of each mounting block via a fixing frame. Two hand-operated hoists on the same support beam share a pull rope. When in use, control the jack to push the T-beam plate to the middle position of the support beam and provide support.

[0004] However, under conditions of tight schedules, excessively long components, and heavy weight, this anti-tipping method is no longer applicable for the following reasons: To address the tight schedule, multiple I-beams need to be transported at once to improve transportation efficiency. When using hydraulic jacks for anti-tipping, the hydraulic jacks can only support the two outermost I-beams, and can only support the portion of the I-beams placed on the transport vehicle. When the I-beams are excessively long, such as 43m long components, both ends of the I-beams extend beyond the transport vehicle, forming long cantilever ends. When the transport vehicle experiences bumps or sharp turns during transportation, the anti-tipping method using hydraulic jacks cannot provide stable support for multiple I-beams, leading to relative movement between the multiple I-beams and the risk of overturning.

[0005] Direct spot welding constraint means directly spot welding the I-beam to the transport vehicle or between adjacent I-beams to form a temporary fixed constraint. However, under conditions such as tight schedule, excessively long components, and heavy weight, this anti-overturning method is no longer applicable for the following reasons: (1) The anti-overturning method of direct spot welding constraint requires workers to perform a large number of spot welding operations between the I-beam and the transport vehicle or between adjacent I-beams, which is a large amount of manual labor, and the subsequent installation and removal of spot welding constraint is difficult, reducing construction efficiency; (2) When the transport vehicle is bumpy or encounters a sharp turn during transportation, for the transportation of multiple long and heavy I-beams, direct spot welding fixation poses a risk of overturning due to easy disturbance of the weld seam, and the temporary fixed constraint formed by spot welding during the turn will cause the structure of the I-beam to deform. Summary of the Invention

[0006] The present invention aims to solve at least one of the problems mentioned in the background art above, and provides an anti-overturning device for long-distance transportation of ultra-long I-beams, which can be applied to the long-distance transportation of multiple ultra-long thin plate easily deformable I-beams at one time, and prevents the overturning of ultra-long I-beams during long-distance transportation.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0008] An anti-tipping device for long-distance transportation of ultra-long I-beams includes an upper crossbeam, a lower crossbeam, and two side wing beams. The lower crossbeam is arranged parallel to and spaced apart from the upper crossbeam. One end of each of the two side wing beams is rotatably connected to the opposite ends of the upper crossbeam, and the other end of each of the two side wing beams is detachably connected to the opposite ends of the lower crossbeam. The two side wing beams, the upper crossbeam, and the lower crossbeam together form a fixed space for fixing the I-beam.

[0009] Furthermore, the upper crossbeam includes a crossbeam body and two mounting seats, the two mounting seats are respectively disposed at opposite ends of the crossbeam body, and one end of each of the two side wing beams is rotatably connected to the two mounting seats.

[0010] Furthermore, the upper crossbeam is horizontally positioned, and the rotation axis of the side wing beam is horizontally positioned and perpendicular to the length direction of the upper crossbeam.

[0011] Furthermore, each of the mounting seats includes two mounting plates, which are arranged at intervals relative to each other and one end is fixed to the bottom surface of the crossbeam body; one end of the side wing beam is inserted between the two mounting plates corresponding to the mounting seat and is rotatably connected to the two mounting plates through a rotating component.

[0012] Furthermore, the upper crossbeam also includes two first lifting lugs, which are respectively fixed to opposite ends of the crossbeam body and are both located on the top surface of the crossbeam body.

[0013] Furthermore, the lower crossbeam includes a crossbeam body and two connecting seats, the two connecting seats being respectively located at opposite ends of the crossbeam body, and the ends of the two side wing beams away from the upper crossbeam being detachably connected to the two connecting seats respectively.

[0014] Furthermore, each of the connecting seats includes two connecting plates, which are arranged at intervals relative to each other and one end is fixed to the top surface of the main body of the crossbeam; the end of the side wing beam away from the upper crossbeam is inserted between the two connecting plates corresponding to the connecting seat and is detachably connected to the two connecting plates through a connector.

[0015] Furthermore, the lower crossbeam also includes two second lifting lugs, which are respectively fixed to the opposite ends of the crossbeam body and respectively disposed on the end faces of the opposite ends of the crossbeam body.

[0016] This invention further provides a method for preventing overturning during long-distance transportation of ultra-long I-beams, comprising the following steps:

[0017] S1, multiple I-beams are placed side by side on the transport vehicle, with the middle part of the I-beams supported on the transport vehicle and the two ends of the I-beams located outside the transport vehicle to form cantilever ends; then, multiple I-beams are tied to the transport vehicle with steel wire ropes to initially fix multiple I-beams to the transport vehicle to form a combined component;

[0018] S2, providing the anti-tipping device for long-distance transportation of the ultra-long I-beam, wherein two such anti-tipping devices are respectively installed on the two cantilever ends of the I-beam, and the anti-tipping device is sleeved on the outside of the combined component formed by the multiple I-beams through the corresponding fixed space. The installation method of the anti-tipping device for long-distance transportation of the ultra-long I-beam is as follows:

[0019] S21, In the initial state, the lower crossbeam and the side wing beam are separated, and the upper crossbeam and the side wing beam are rotatably connected.

[0020] S22, the semi-finished product formed by connecting the upper crossbeam and the side wing beam is hoisted onto the corresponding cantilever end, so that the upper crossbeam is supported on the top surface of the multiple I-beams, and the two side wing beams are respectively located on opposite sides of the combined component composed of the multiple I-beams;

[0021] S23, the lower crossbeam is lifted upward to the bottom end of the side wing beam by hoisting equipment, and the opposite ends of the lower crossbeam are connected to the bottom ends of the two side wing beams respectively, so that the lower crossbeam is supported on the bottom surface of the multiple I-beams, and the two side wing beams are respectively clamped on the opposite sides of the combined component.

[0022] Furthermore, after the multiple I-beams arrive at their destination, firstly, the steel wire ropes connecting the combined component and the transport vehicle are removed. Then, two hoisting devices are connected to the anti-tipping devices for long-distance transport of the two ultra-long I-beams, and the anti-tipping devices and the combined component are lifted together by the hoisting devices to transport the anti-tipping devices and the combined component from the transport vehicle to the preset storage location. Finally, the connection between the lower crossbeam and the two side wing beams is released, and the semi-finished product composed of the upper crossbeam and the two side wing beams is lifted as a whole by the hoisting devices to detach the semi-finished product from the combined component.

[0023] By adopting the above technical solution, the present invention has the following beneficial effects:

[0024] After multiple I-beams are initially fixed onto the transport vehicle, two extra-long I-beam long-distance transport anti-tipping devices are installed on the two cantilever ends of the I-beams located outside the transport vehicle. These devices, through corresponding fixed spaces, are fitted over the combined component formed by the multiple I-beams to constrain the cantilever ends of the I-beams outside the transport vehicle. This improves the stability of the extra-long I-beams during transport and small-radius turns, preventing overturning during long-distance transport. Compared to the temporary consolidation method of spot welding in existing technologies, this extra-long I-beam long-distance transport anti-tipping device minimizes the risk of torsional deformation of the I-beams. Furthermore, this device is suitable for the long-distance transport of multiple extra-long, thin-plate, easily deformable I-beams, improving transport efficiency.

[0025] The aforementioned anti-tipping device for long-distance transport of ultra-long I-beams can be used as a lifting tool after multiple I-beams have been transported to the designated location. This allows multiple I-beams to be lifted simultaneously from the transport vehicle to the preset storage position, improving unloading efficiency. Furthermore, using the anti-tipping device as a lifting tool reduces the likelihood of deformation during the lifting process of ultra-long I-beams.

[0026] The aforementioned anti-tipping device for long-distance transportation of ultra-long I-beams is easy to install and dismantle, enabling rapid assembly and disassembly of multiple I-beams and improving construction efficiency. Attached Figure Description

The lower crossbeam 30 is arranged parallel to and spaced apart from the upper crossbeam 10. One end of each side wing beam 50 is rotatably connected to the opposite ends of the upper crossbeam 10, and the other end of each side wing beam 50 is detachably connected to the opposite ends of the lower crossbeam 30.

[0039] In this embodiment, the upper crossbeam 10 is horizontally arranged. The upper crossbeam 10 includes a crossbeam body 11, two mounting seats 13 and two first lifting lugs 15.

The provision of the first stiffening plates 116 can increase the rigidity of the upper crossbeam 10. In this embodiment, the first stiffening plate 116 is disposed near the end of the first I-beam 110.

[0041] Two mounting bases 13 are respectively disposed at opposite ends of the bottom surface of the crossbeam body 11. Each mounting base 13 includes two mounting plates 131, which are arranged at intervals and one end is fixed to the bottom surface of the crossbeam body 11. In this embodiment, the two mounting plates 131 are arranged at intervals along the width direction of the crossbeam body 11, and one end of the mounting plate 131 is fixed to the bottom surface of the first lower flange plate 114. Each mounting plate 131 is provided with a mounting hole 132. In this embodiment, two first lifting lugs 15 are respectively fixed to opposite ends of the top surface of the first upper flange plate 113.

[0042] In this embodiment, the lower crossbeam 30 is horizontally arranged. The lower crossbeam 30 includes a crossbeam body 31, two connecting seats 33 and two second lifting lugs 35. The two connecting seats 33 are respectively located at opposite ends of the crossbeam body 31. The two second lifting lugs 35 are respectively fixed to opposite ends of the crossbeam body 31 and are respectively located on the end faces of opposite ends of the crossbeam body 31.

[0043] In this embodiment, the main body 31 of the crossbeam is generally rectangular in shape, including a second I-beam 310, two second end plates 315, and a plurality of second stiffening plates 316. The structure of the second I-beam 310 is prior art, including a second vertical plate 312, a second upper flange plate 313 vertically fixed to the top of the second vertical plate 312, and a second lower flange plate 314 vertically fixed to the bottom of the second vertical plate 312.

A plurality of second stiffening plates 316 are respectively disposed on opposite sides of the second vertical plate 312, and each second stiffening plate 316 is fixedly connected to the side face of the second vertical plate 312, the second upper flange plate 313, and the second lower flange plate 314. The provision of the second stiffening plates 316 can increase the rigidity of the lower crossbeam 30. In this embodiment, the second stiffening plate 316 is disposed near the end of the second I-beam 310.

[0044] Two connecting seats 33 are respectively disposed at opposite ends of the top surface of the crossbeam body 31. Each connecting seat 33 includes two connecting plates 331, which are arranged relatively apart and one end is fixed to the top surface of the crossbeam body 31. In this embodiment, the two connecting plates 331 are arranged relatively apart along the width direction of the crossbeam body 31, and one end of the connecting plate 331 is fixed to the top surface of the second upper flange plate 313. Each connecting plate 331 is provided with a connecting hole 332. In this embodiment, two second lifting lugs 35 are respectively fixed to the outer side of the two second end plates 315 facing away from the second I-beam 310.

[0045] One end of each side wing beam 50 is rotatably connected to one of the two mounting bases 13. In this embodiment, the top end of the side wing beam 50 is inserted between the two mounting plates 131 of the corresponding mounting base 13 and is rotatably connected to the two mounting plates 131 via a rotating member 80. The rotation axis of the side wing beam 50 is horizontally set and perpendicular to the length direction of the upper crossbeam 10. Specifically, the top end of the side wing beam 50 is provided with a rotating hole 51; the rotating member 80 is a bolt, which includes a first screw part 82 with a first bolt head 81 and a first nut 83 that mates with the first screw part 82. During installation, the first screw part 82 passes through the mounting holes 132 of the two mounting plates 131 and the rotating hole 51 at the top end of the side wing beam 50 to rotatably connect the top end of the side wing beam 50 to the upper crossbeam 10. The first nut 83 is threaded onto the end of the first screw portion 82 that is away from the first bolt head 81, so that both mounting plates 131 are located between the first bolt head 81 and the first nut 83, thereby preventing the side wing beam 50 from accidentally detaching from the upper crossbeam 10 through the cooperation of the first bolt head 81 and the first nut 83.

[0046] The ends of the two side wing beams 50 away from the upper crossbeam 10 are detachably connected to the two connecting seats 33. In this embodiment, the bottom end of the side wing beam 50 away from the upper crossbeam 10 is inserted between the two connecting plates 331 of the corresponding connecting seats 33 and is detachably connected to the two connecting plates 331 through a connector 90. Specifically, the bottom end of the side wing beam 50 is provided with an insertion hole 52; the connector 90 is a bolt, and the connector 90 includes a second threaded part 92 with a second bolt head 91 and a second nut 93 that mates with the second threaded part 92. During installation, the second threaded part 92 passes through the connecting hole 332 of the two connecting plates 331 and the insertion hole 52 at the bottom end of the side wing beam 50 to detachably connect the bottom end of the side wing beam 50 to the lower crossbeam 30. The second nut 93 is threaded onto the end of the second screw portion 92 that is away from the second bolt head 91, so that both connecting plates 331 are located between the second bolt head 91 and the second nut 93, thereby preventing the side wing beam 50 from accidentally separating from the lower crossbeam 30 through the cooperation of the second bolt head 91 and the second nut 93.

[0047] This invention also provides a method for preventing overturning during long-distance transportation of ultra-long I-beams, comprising the following steps:

[0048] S1, multiple I-beams 210 are placed side by side on the transport vehicle 300, with the middle part of the I-beams 210 supported on the transport vehicle 300 and the two ends of the I-beams 210 located outside the transport vehicle 300 to form cantilever ends; then, multiple I-beams 210 are tied to the transport vehicle 300 by steel wire ropes 400 to initially fix multiple I-beams 210 on the transport vehicle 300 to form a composite component 200.

[0049] S2 provides an anti-tipping device 100 for long-distance transport of ultra-long I-beams. Two ultra-long I-beam anti-tipping devices 100 are respectively installed on the two cantilever ends of the I-beam 210 located outside the transport vehicle 300. The ultra-long I-beam anti-tipping device 100 is fitted onto the combined component 200 formed by multiple I-beams 210 through corresponding fixing spaces 60. The installation method of the ultra-long I-beam anti-tipping device 100 is as follows:

[0050] S21, In the initial state, the lower crossbeam 30 and the side wing beam 50 are separated, while the upper crossbeam 10 and the side wing beam 50 are rotatably connected.

[0051] S22, the semi-finished product formed by connecting the upper crossbeam 10 and the side wing beams 50 is hoisted onto the corresponding cantilever end, so that the upper crossbeam 10 is supported on the top surface of multiple I-beams 210, and the two side wing beams 50 are respectively located on opposite sides of the combined component 200 composed of multiple I-beams 210; specifically, in this embodiment, hoisting equipment such as gantry cranes can be used for hoisting.

[0052] Specifically, the two extra-long I-beam long-distance transport anti-tipping devices 100 are respectively installed on the two cantilever ends of the I-beam 210 located outside the transport vehicle 300, and the distance between the extra-long I-beam long-distance transport anti-tipping device 100 and the free end of the corresponding cantilever end is approximately 1 / 3 of the length of the I-beam 210. During the hoisting of the semi-finished product, the first lifting lug 15 of the upper crossbeam 10 is connected to the hoisting equipment through a hoisting wire rope.

[0053] S23, the lower crossbeam 30 is lifted upward to the bottom end of the side wing beam 50 by lifting equipment such as gantry crane, and the two opposite ends of the lower crossbeam 30 are connected to the bottom ends of the two side wing beams 50 respectively, so that the lower crossbeam 30 is supported on the bottom surface of multiple I-beams 210, and the two side wing beams 50 are respectively clamped on the opposite sides of the composite component 200.

[0054] Specifically, when connecting the opposite ends of the lower crossbeam 30 to the bottom ends of the two side wing beams 50, the second screw portion 92 of the connector 90 passes through the connecting holes 332 of the two connecting plates 331 and the insertion holes 52 at the bottom of the side wing beams 50, so as to detachably connect the bottom ends of the side wing beams 50 to the lower crossbeam 30; the second nut 93 of the connector 90 is threaded onto the end of the second screw portion 92 away from the second bolt head 91, so that both connecting plates 331 are located between the second bolt head 91 and the second nut 93. When hoisting the lower crossbeam 30, the second lifting lug 35 of the lower crossbeam 30 is connected to the hoisting equipment by a hoisting wire rope.

[0055] After multiple I-beams 210 arrive at their destination, they need to be transferred from the transport vehicle 300 to a pre-designated storage location, which includes the following steps:

[0056] First, remove the steel wire rope 400 connecting the combined component 200 and the transport vehicle 300.

[0057] Secondly, two lifting devices, such as gantry cranes, are connected to the two extra-long I-beam long-distance transport anti-tipping devices 100 respectively. The two extra-long I-beam long-distance transport anti-tipping devices 100 and the combined component 200 are then lifted together by the lifting devices to transport them from the transport vehicle 300 to a predetermined storage location. In this embodiment, the first lifting lug 15 of the upper crossbeam 10 is connected to the lifting device via a lifting wire rope, and then the two extra-long I-beam long-distance transport anti-tipping devices 100 and the combined component 200 are lifted together by the lifting device. After the combined component 200 is lifted from the transport vehicle 300 to the predetermined storage location, the lower crossbeam 30 is supported on the ground or support frame at the predetermined storage location.

[0058] Finally, disconnect the lower crossbeam 30 from the two side wing beams 50, and then use hoisting equipment to lift the semi-finished product consisting of the upper crossbeam 10 and the two side wing beams 50 as a whole, so that the semi-finished product can be separated from the combined component 200.

[0059] In this embodiment, when disconnecting the lower crossbeam 30 from the two side wing beams 50, the second nut 93 of the connector 90 can be unscrewed from the second screw portion 92, and then the second screw portion 92 of the connector 90 can be directly pulled away from the connecting seat 33 and the side wing beams 50. Finally, the semi-finished product consisting of the upper crossbeam 10 and the two side wing beams 50 is lifted as a whole by hoisting equipment to detach the semi-finished product from the assembly component 200. At the same time, since the side wing beams 50 and the upper crossbeam 10 are rotatably connected, during the hoisting of the semi-finished product, the worker can rotate the side wing beams 50 to a position away from the I-beam 210, and then tighten the first nut 83 to clamp the side wing beams 50 with the two mounting plates 131, so that the side wing beams 50 are kept away from the I-beam 210, avoiding collision between the side wing beams 50 and the I-beam 210 during the hoisting process. The lower crossbeam 30 can be used to support the I-beam 210. After the I-beam 210 above the lower crossbeam 30 is removed, the lower crossbeam 30 can be recycled for reuse. Alternatively, after the semi-finished product consisting of the upper crossbeam 10 and the two side wing beams 50 is separated from the composite component 200, the hoisting equipment can be connected to several I-beams 210, and after the several I-beams 210 are lifted upwards a certain distance, the lower crossbeam 30 can be taken out and recycled for reuse.

[0060] After multiple I-beams 210 are initially fixed onto the transport vehicle 300, two extra-long I-beam long-distance transport anti-tipping devices 100 are respectively installed on the two cantilever ends of the I-beams 210 located outside the transport vehicle 300. The extra-long I-beam long-distance transport anti-tipping devices 100 are fitted onto the two cantilever ends of the multiple I-beams 210 through corresponding fixing spaces 60, so as to constrain the cantilever ends of the I-beams 210 located outside the transport vehicle 300, improve the stability of the extra-long I-beams 210 during transportation and small-radius turns, prevent the extra-long I-beams from overturning during long-distance transportation, and minimize the possibility of twisting deformation of the I-beams 210; and can be applied to the long-distance transportation of multiple extra-long thin plate easily deformable I-beams at one time, thus improving the transportation efficiency.

[0061] The aforementioned anti-tipping device 100 for long-distance transport of ultra-long I-beams can be used as a lifting tool after multiple I-beams 210 have been transported to the designated location. This allows multiple I-beams 210 to be simultaneously lifted from the transport vehicle 300 to the preset storage position, improving unloading efficiency.
