Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, specifically a steel box girder segment transportation device. Background Technology

[0002] In modern bridge and building engineering, steel box girders are used as the main load-bearing components. They have good strength and stability. In combination with the construction site conditions, water transport is generally used to transport the segmental girders to the hoisting location.

[0003] Chinese utility model patent CN218199338U discloses a modular steel box girder segmental barge transport frame: it includes four steel pipe columns forming a square frame. Each steel pipe column has horizontally extending channel steel braces on its adjacent sides. Each channel steel brace has several pre-drilled bolt holes. The channel steel braces between two horizontally adjacent steel pipe columns are connected back-to-back, and the pre-drilled bolt holes of the two channel steel braces partially or completely overlap. The horizontally adjacent steel pipe columns are fixed by bolts passing through the pre-drilled bolt holes. The channel steel braces between two longitudinally adjacent steel pipe columns are also connected back-to-back, and the pre-drilled bolt holes of the two channel steel braces partially or completely overlap. The longitudinally adjacent steel pipe columns are fixed by bolts passing through the pre-drilled bolt holes.

[0004] However, existing technologies still have shortcomings:

[0005] The above solutions only adjust the length and width of the support base, which can support steel box girder sections of different sizes, but cannot limit their movement, affecting the stability of the equipment during transportation. Utility Model Content

[0006] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a steel box girder segment transportation device, which solves the problem in the prior art that it cannot achieve limiting of steel box girder segments of different sizes, affecting the stability of the device during transportation.

[0007] To achieve the above objectives, this utility model proposes a steel box girder segment transportation device, including a barge. A support frame is fixedly installed on the barge, and several sleepers are fixedly arranged on the support frame. A steel box girder segment body is placed on the sleepers. Two diagonal braces are respectively arranged on both sides of the steel box girder segment body. One end of the diagonal brace abuts against the support frame, and the other end abuts against the steel box girder segment body. Two steel ropes are arranged in both the transverse and longitudinal directions of the steel box girder segment body for binding and reinforcing the steel box girder segment body.

[0008] As a further embodiment of this utility model, an anti-slip pad is fixedly provided on the sleeper.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] To prevent the steel box girder segments from overturning or sliding during transportation, binding and reinforcement devices are installed on the segments.

[0024] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] like Figure 1-4 As shown, a steel box girder segment transportation device includes a barge 1, which is equipped with a ballast pump. A support frame 3 is fixedly installed on the barge 1, and several sleepers 4 are fixedly arranged on the support frame 3. Anti-slip pads 5 are fixedly arranged on the sleepers 4, and steel box girder segments 7 are placed on the sleepers 4. The length direction of the steel box girder segments 7 is along the center line of the bow and stern of the barge 1 deck, which can reduce the tilt of the barge 1 during transportation. Due to the uneven weight distribution along the length direction of the segments, the barge 1 may still experience longitudinal tilt after loading. When longitudinal tilt occurs, the ballast water can be adjusted by the barge's own ballast pump to maintain the balance of the hull. Two diagonal braces 8 are respectively arranged on both sides of the steel box girder segments 7. The diagonal braces 8 are symmetrically distributed on both sides of the steel box girder segments 7. One end of the steel box girder abuts against the support frame 3, and the other end abuts against the steel box girder segment body 7. Two wedge blocks 6 are provided on the top and bottom plates of the steel box girder segment body 7. The wedge blocks 6 are placed between the steel box girder segment body 7 and the barge 1 to increase the stability of the steel box girder segment body 7. Two steel ropes 9 are provided in the horizontal and vertical directions of the steel box girder segment body 7. The steel ropes 9 are used to bind and reinforce the steel box girder segment body 7. The support frame 3 is provided with a guide groove 12 to facilitate the steel ropes 9 set in the width direction of the steel box girder segment body 7 to pass through the guide groove 12 and bind the steel box girder segment body 7. In this embodiment, the anti-slip pad 5 is a rubber pad. In specific implementation, it can also be a plastic pad or a composite anti-slip material. During installation, fireproof cloth is wrapped at all contact points between the binding structure and the coating surface of the beam segment to prevent damage to the coating layer. In this application, the steel box girder segment 7 is laid down and then limited; the specific reason is that the height of the steel box girder segment 7 exceeds the height limit of the bridges passed in the transportation route. In specific implementation, the installation method can be selected according to the road conditions.

[0026] As one embodiment of this example, the diagonal brace 8 includes a support rod 10 and a top plate 11. The support rod 10 and the top plate 11 are rotatably connected. The top plate 11 abuts against the steel box girder segment body 7, and the support rod 10 abuts against the support frame 3.

[0027] As one implementation method in this embodiment, a fence 2 is fixedly installed on the barge 1 to increase the safety of workers during construction.

[0028] After the main body 7 of the steel box girder is installed, it can be transported. Considering the characteristics of wind, waves, and currents in the navigation area, the segments are tied and fixed according to the lashing plan after being loaded onto the ship. During navigation, the operators should frequently check the lashing and fixing, and take measures such as tightening if there is any loosening. After being transported to the hoisting point below the bridge site to be processed, it can be hoisted after being anchored and positioned. The barge 1 should not stop its engine during hoisting. The engine and rudder effect should be used to assist in adjusting and stabilizing the position of the transport ship, and to be ready for emergency response at any time. In order to ensure the positioning effect of the transport ship in the case of large water flow, an anchored boat can be used for auxiliary positioning to ensure the positioning and adjustment of the barge 1.

[0029] Working principle:

[0030] First, the steel box girder segment 7 is placed along the center line of the bow and stern of the deck of the barge 1. The steel box girder segment 7 is placed on the sleepers 4. Then, two wedge blocks 6 are set on the top and bottom plates of the steel box girder segment 7. The wedge blocks 6 are placed between the steel box girder segment 7 and the barge 1. Next, two diagonal braces 8 are installed on both sides of the steel box girder segment 7 to abut the top plate 11 and the steel box girder segment 7. The support rod 10 abuts the support frame 3. Two steel ropes 9 are set in the horizontal and vertical directions of the steel box girder segment 7 to bind and reinforce it. Then, the barge 1 is started for transportation. After the barge 1 is transported to the lifting point below the bridge site, the limiting of the steel ropes 9 and the diagonal braces 8 is removed. The steel box girder is flipped and straightened by the bridge deck crane and then lifted onto the bridge.
