Description

Technical Field

[0001] This utility model relates to the field of bridge construction, and in particular to a bridge concrete pouring system. Background Technology

[0002] Traditional bridge engineering concrete pouring involves pumping concrete into the formwork using a concrete pump or lifting it in using a tower crane or truck crane. This method has several drawbacks for bridge concrete pouring construction: ① In complex mountainous areas with ravines, the terrain and weather conditions result in extremely poor transportation conditions, making it difficult to transport high-quality sand and gravel raw materials. The local sand and gravel raw materials are poorly mixed with cement and other additives, making it impossible to pump concrete.

[0003] ② The bridge is designed to span a long distance across the valley. Due to the limitations of the long-span bridge and the valley terrain, the lifting range of tower cranes and other hoisting machinery is insufficient to cover the pouring area.

[0004] ③ The vertical height of the concrete pouring section of the bridge project exceeds 100 meters, and the horizontal length is 100 meters. The installation and dismantling of the pump pipe takes a long time, is dangerous, and is difficult to deal with. Utility Model Content

[0005] The purpose of this utility model is to provide a bridge concrete pouring system that addresses the problem that existing technologies, such as pumping concrete into the formwork or using tower cranes or truck cranes, are not suitable for bridges with long spans across river valleys in mountainous areas.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A bridge concrete pouring system includes a gantry assembly, a lifting assembly, a hopper, a transport trolley, and a shuttle. The gantry assembly is located at the end of a pre-formed concrete segment of the bridge. The lifting assembly is connected to the gantry assembly. The hopper is used for loading and unloading concrete, and the lifting assembly can connect to and lift the hopper. The transport trolley transports the hopper to a position below the gantry assembly. The shuttle is located below the lifted hopper and is used to guide the concrete unloaded from the hopper to the area of ​​the concrete segment to be poured in front of the pre-formed concrete segment.

[0007] The bridge concrete pouring system described in this utility model, through the combination of the hopper loading and the transport trolley, can transport concrete to the gantry assembly. By setting up the gantry assembly and the lifting assembly, the system achieves high strength and can withstand the lifting of large volumes of concrete. The hopper is lifted, and the chute guides the unloaded concrete from the hopper to the pouring area. Thus, in the construction of long-span bridges crossing river valleys in mountainous areas, it is not necessary to pump concrete into the formwork or use tower cranes or truck cranes for hoisting. This concrete pouring system has a simple structure, is easy to use, and has good performance.

[0008] As a preferred technical solution of this utility model, the lifting assembly includes a hanger, an electric hoist, and a hoisting rope. The electric hoist is connected to the gantry assembly, and the electric hoist is connected to the hanger via the hoisting rope. The hanger is detachably connected to the hopper.

[0009] As a further preferred technical solution of this utility model, the hanger includes a cross, with an upper lifting lug connected to the top of the center position of the cross, the upper lifting lug being connected to the lifting rope, and lower lifting lugs connected to the bottom of the four ends of the cross, the lower lifting lugs being detachably connected to the hopper.

[0010] As a further preferred technical solution of this utility model, the lower lifting lug is connected to the hopper by a hanging rope.

[0011] As a preferred technical solution of this utility model, the gantry assembly includes four columns. Two adjacent columns in the transverse direction are connected by a crossbeam, and two adjacent columns in the longitudinal direction are connected by a longitudinal beam. The longitudinal beam is disposed on the crossbeam, and a load-bearing beam is connected to the longitudinal beam. The load-bearing beam is connected to the lifting assembly.

[0012] As a further preferred technical solution of this utility model, the column and the corresponding crossbeam are connected by diagonal bracing.

[0013] As a further preferred technical solution of this utility model, a horizontal connecting rod is connected between two adjacent columns in the transverse direction, and a longitudinal connecting rod is connected between two adjacent columns in the longitudinal direction.

[0014] As a further preferred technical solution of this utility model, a suspension component is connected to the gantry assembly, and the suspension component is used to detachably connect the gantry assembly to the diamond-shaped hanging basket flower rack.

[0015] With this structural design, the gantry assembly is detachably connected to the diamond-shaped hanging basket flower rack via the suspension assembly, allowing the gantry assembly to move with the diamond-shaped hanging basket flower rack to the next construction section without the need for a separate drive mechanism. This makes movement convenient and quick, reduces the use of hoisting machinery, and lowers construction costs.

[0016] As a further preferred technical solution of this utility model, the suspension assembly includes a first hanging ear and a second hanging ear. The first hanging ear is connected to two columns close to the concrete segment to be poured, and the second hanging ear is connected to two columns away from the concrete segment to be poured.

Thus, in the construction of bridges with large spans across river valleys in mountainous areas, it is not necessary to pump concrete into the formwork or use tower cranes, truck cranes, etc. to lift it into the formwork. This concrete pouring system has a simple structure, is easy to use, and has good effect. 2.

[0021] The present invention will be further described in detail below with reference to experimental examples and specific embodiments. However, this should not be construed as limiting the scope of the above-mentioned subject matter of the present invention to the following embodiments. All technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0022] Unless otherwise specified, the use of terms such as "upper," "lower," "left," "right," "center," "inner," and "outer" to indicate orientation or positional relationships in the description of specific embodiments of this utility model is based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product / equipment / device is typically placed during use. These terms are merely for the purpose of facilitating the description of the utility model solution or simplifying the description in specific embodiments, enabling those skilled in the art to quickly understand the solution, and do not indicate or imply that a specific device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship. Therefore, they should not be construed as limitations on this utility model.

[0023] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," and "parallel" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, or parallel, but rather that it can be slightly tilted or have a deviation. For example, "horizontal" merely means that its direction is more horizontal relative to "vertical," not that the structure must be completely horizontal, but can be slightly tilted. Alternatively, it can be simplified to mean that the corresponding device / component / element, when set in a "horizontal," "vertical," "suspended," or "parallel" direction, can have an error / deviation of ±10% relative to the corresponding direction, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and more preferably within ±4%. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the present invention.

Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0027] In related technologies, complex mountainous terrain and weather conditions result in extremely poor transportation, making it difficult to transport high-quality sand and gravel raw materials. Local sand and gravel raw materials also have poor mixing effects with cement and other additives, making concrete pumping impossible. Furthermore, the bridge design involves a 180m span across a river valley, and the limitations imposed by the large span and valley terrain mean that the lifting range of tower cranes and other hoisting machinery is insufficient to cover the pouring area. Therefore, the technical solution of this application was developed, which is described below in conjunction with… Figures 1 to 9 To elaborate.
