Description

Technical Field

[0001] The utility model relates to the field of arch bridge construction, in particular to a construction device for a through arch bridge. Background Art

[0002] Arch bridges are one of the most widely used bridge structures. When constructing an arch bridge and installing the middle cross beam and arch rib support, a steel trestle is mostly built on one side of the bridge, and then a floating crane, crawler crane or truck crane is used to hoist the middle cross beam or arch rib support. The traditional construction method is to build a steel trestle and then the crane goes onto the steel trestle for construction. The width of the steel trestle must meet the requirements of the crane, wasting a large amount of materials. This construction method has a high cost and low construction efficiency. A floating crane usually requires a ship and is usually used for water construction, relying on buoyancy to support the equipment, with low construction efficiency and high construction cost. Crawler cranes and truck cranes are restricted under poor ground conditions and may not be applicable in all construction environments. At the same time, the temporary steel trestle built after the traditional through arch bridge construction is relatively difficult to disassemble, time-consuming and laborious. It is also relatively difficult to hoist the middle cross beam and arch rib support during the hoisting process, wasting a lot of manpower and material resources. For this reason, we propose a construction device for a through arch bridge to solve the above problems. Content of the Utility Model

[0003] The utility model provides a construction device for a through arch bridge, which solves the problems that when using a floating crane, crawler crane or truck crane to hoist the middle cross beam or arch rib support to build an arch bridge, it is necessary to build and disassemble a steel trestle, with a high construction cost, low construction efficiency, and time-consuming and laborious during the hoisting process of the middle cross beam and arch rib support.

[0004] To solve the above technical problems, the technical solution adopted by the utility model is: a construction device for a through arch bridge, including two rows of side beam frames and two rows of bottom beam frames. The side beam frames are located outside the bottom beam frames. A connecting beam system is provided between the side beam frames and the bottom beam frames. Two moving gantry cranes are provided on the side beam frames. A traveling lifting beam is provided on the gantry cranes. A plurality of sliding lifting blocks are provided on the lifting beam;

[0006] On one side of the end side beam frame, a transport vehicle is provided, and the transport vehicle is used to transport the middle cross beam, arch rib support, side beam frame and bottom beam frame;

[0007] Tracks are provided on the top of the side beam frames, and electrical systems are provided at the bottoms on both sides of the gantry cranes.

[0008] In a preferred solution, the two ends of the gantry crane abut against the tracks and slide, a horizontally moving crane is provided on the gantry crane, and side hoisting winches are provided on both sides of the gantry crane.

[0009] In the preferred solution, a pile cap, a main cross beam, a main longitudinal beam, and a distribution beam are successively arranged on the top of the side beam frame and the bottom beam frame. The track is arranged on the distribution beam of the side beam frame. The bottom beam frame includes a plurality of second pile foundations. Top lifting lugs, a plurality of side lifting lugs, and a plurality of bottom lifting lugs are arranged on the bottom beam frame. A wire pulley is arranged on one side of the distribution beam at the top of the side beam frame.

[0010] In the preferred solution, the lifting beam includes main beams on both sides. The main beams are connected to the crane. A plurality of sliding lifting blocks are arranged on the main beams. Electric hoists are arranged at the bottoms of the lifting blocks. Positioning grooves are arranged on the main beams. A lead screw is arranged between the two main beams, and a motor is arranged at the end of the lead screw.

[0011] In the preferred solution, a hydraulic cylinder is arranged on the lifting block. A bearing bush is arranged at the top of the hydraulic cylinder. The bearing bush is connected to the lead screw. Telescopic second hydraulic cylinders are arranged on both sides of the lifting block. The second hydraulic cylinders abut against the positioning grooves on the main beam.

[0012] In the preferred solution, the connecting beam system includes a plurality of hoops installed on the first pile foundation and a plurality of ring frames installed on the second pile foundation. Connecting tie rods are arranged between the hoops and the ring frames at the horizontal position. A rotating device is arranged on the hoops at the horizontal position.

[0013] In the preferred solution, the rotating device includes a turntable rotatably connected to the hoop. A plurality of grooves are arranged on the hoop. Supports are arranged on both sides of the turntable. A rotating locking rod is arranged on the support. A locking block is arranged at one end of the locking rod. A hinged cylinder is arranged at the other end of the locking rod. The cylinder is installed on the hoop.

[0014] In the preferred solution, a connecting column is arranged on the ring frame. The connecting tie rod includes a first connecting rod and a second connecting rod. A bidirectional screw is arranged between the first connecting rod and the second connecting rod. The first connecting rod is connected to the turntable. A plurality of rotatably connected clamps are arranged at one end of the second connecting rod. The clamps are clamped on the connecting column. Both ends of the connecting column are connected to the ring frame through nuts.

[0015] The beneficial effects of the present utility model are as follows: Through the cooperation of the gantry crane and the lifting beam, the side beam frame and the bottom beam frame are successively erected to form a support platform from both ends of the river. The side beam frame and the bottom beam frame are connected by a connecting beam system. Similarly, the middle cross beam is hoisted from both ends of the river to the center by the gantry crane to build the bridge deck on the support platform. After the bridge deck is built, the arch rib support is hoisted through the cooperation of the gantry crane and the lifting beam until the entire bridge is built. Then, in the reverse order, through the cooperation of the gantry crane and the lifting beam, the side beam frame, the bottom beam frame, and the arch rib support are successively disassembled and hoisted from the middle to both ends of the river. The whole device does not require a steel trestle during the process of building the arch bridge, and at the same time, it does not require floating cranes, crawler cranes, or truck cranes to complete the hoisting. The gantry crane and the lifting beam can complete the whole process from installation and construction to disassembly, with high use efficiency, greatly reducing the construction cost, avoiding the process of temporarily building and disassembling the steel trestle, saving time and effort, and greatly saving materials.

[0016] The side hoists on both sides of the gantry crane and the crane and lifting beam at the top cooperate with each other, enabling the lifting of the bottom beam support installed at the bottom of the bridge to the top of the bridge. Then, through coordinated operation, the bottom beam support can be flipped, turning the vertically placed bottom beam support to a horizontal state. Subsequently, it is moved to the transport vehicle by the gantry crane, completing the process of lifting the bottom beam support installed at the bottom of the bridge to the top of the bridge, avoiding the complex construction of using a floating crane with a floating ship to lift the bottom beam support, and greatly saving costs. Similarly, the gantry crane and the lifting beam cooperate with each other, enabling the in-air flipping of the side beam support and the arch rib support, lifting the vertically placed lifted object to a horizontal state, greatly facilitating the lifting process, and enabling the direct lifting and unloading of the lifted object from the transport vehicle, avoiding the process of using other equipment for flipping operations in the middle and accelerating the construction efficiency.

[0017] The overall device has high safety, replacing the traditional process that requires a crane on a steel trestle; it is highly efficient in construction. Since the gantry crane and the lifting beam have a flipping function, the transport vehicle directly transports the relevant structure to the bottom on one side of the bridge, and the gantry crane can directly lift and install the relevant structure from the bottom of the bridge; it has good economic benefits, saves materials, and is fast and efficient in construction. At the same time, it avoids the phenomenon of wasting materials in the traditional construction method of building a steel trestle.

[0018] The connection beam system can be connected and disassembled quickly. By rotating the bidirectional screw, the connecting tie rod can be telescopically tightened, and the hoop can be quickly installed and removed on the side beam support. The fixture at the end of the connecting tie rod can be quickly installed and removed on the bottom beam support. The connecting tie rod can adapt to different distances between the side beam support and the bottom beam support. At the same time, when the bottom beam support and the side beam support are being installed, due to inevitable factors such as the river or the uneven bottom of the riverbed causing deflection and inclination, the rotating device on the hoop can rotate and lock, enabling the connection beam system to connect two relatively inclined supports, so that the side beam support, the bottom beam support, and the connection beam system are connected into a whole, making the overall structure stable, capable of withstanding the impact of the river water, facilitating the installation and construction of the bridge deck, and having great popularization value.

They are connected by the connecting beam system 6 between the side beam frame 4 and the bottom beam frame 5. Similarly, the middle cross beam 8 is hoisted from both ends of the river to the center by the gantry crane 1 to build the bridge deck on the support platform. After the bridge deck is built, the arch rib support 9 is hoisted by the cooperation of the gantry crane 1 and the hanging beam 7 until the entire bridge is built. Then, in the reverse order, through the cooperation of the gantry crane 1 and the hanging beam 7, the side beam frame 4, the bottom beam frame 5 and the arch rib support 9 are sequentially disassembled and hoisted from the middle to both ends of the river. The overall device does not require a steel trestle during the process of building the arch bridge, and at the same time, it does not require floating cranes, crawler cranes or truck cranes to complete the hoisting. The gantry crane 1 and the hanging beam 7 can complete the whole process from installation and construction to disassembly, with high use efficiency, greatly reducing the construction cost, avoiding the process of temporarily building and disassembling the steel trestle, saving time and effort, and greatly saving materials.

Then, it is moved to the transport vehicle 10 by the gantry crane 1, realizing the process of hoisting the bottom beam frame 5 installed at the bottom of the bridge to the top of the bridge, avoiding the complex construction of hoisting the bottom beam frame 5 using a floating ship with a floating crane, and greatly saving the cost. Similarly, the gantry crane 1 and the hanging beam 7 cooperate with each other, and can flip the side beam frame 4 and the arch rib support 9 in the air, and can hoist the vertically placed hoisted object to the horizontal state, greatly facilitating the hoisting process, and can directly lift and unload the hoisted object from the transport vehicle 10, avoiding the process of using other equipment for flipping operations in the middle, and accelerating the construction efficiency.

[0043] The overall device has high safety, replacing the traditional process that requires a crane to access the steel trestle; it is highly efficient in construction. Since the gantry crane 1 and the hanging beam 7 have a flipping function, the transport vehicle 10 can directly transport the relevant structures to the bottom of one side of the bridge, and the gantry crane 1 can directly hoist and install the relevant structures from the bottom of the bridge; it has good economic benefits, saves materials, and is fast and efficient in construction. At the same time, it avoids the phenomenon of wasting materials in the traditional construction method of building a steel trestle.
