Description

Technical Field

[0001] This utility model belongs to the field of box girder end sealing technology, specifically relating to a railway box girder end sealing device. Background Technology

[0002] With the rapid development of high-speed railways, high efficiency in individual construction processes is essential to meet the overall construction needs. In the prefabrication of box girders, construction teams must be able to complete the end-sealing of at least two spans per day. The supply of concrete and the accurate installation of the end-sealing device determine the daily progress of the end-sealing work. In the past, end-sealing operations mostly used sleepers and clips to fix the end-sealing baffles, which did not provide adequate fixation and was time-consuming and labor-intensive. Moreover, during construction, loosening of the fixation could affect the quality of the finished product, and even slippage of the device could lead to concrete waste, wasted time and labor, and delays in the construction schedule. Summary of the Invention

[0003] The purpose of this invention is to provide a railway box girder end sealing device to address the problem of concrete leakage caused by loose end seals on box girders.

[0004] The technical solution of this utility model: A railway box girder end sealing device includes an open steel plate 1, which is circular with a square opening at one end. Two fan-shaped baffles 2 are vertically welded to the two sides of the square opening. The bottom edge of the square opening is carved out into the two sides to form mounting grooves. A fan-shaped half-section baffle 3 is installed on the opening. The shape of the fan-shaped half-section baffle 3 is the same as the shape of the opening. The bottom ends of the fan-shaped half-section baffle 3 have extending shafts, which are placed in the mounting grooves. The front side of the mounting groove is blocked by the two fan-shaped baffles 2, and the rear side of the mounting groove is blocked by a stop block 6, which is welded and fixed to the open steel plate 1.

[0005] A hole is made in the middle of the open steel plate 1 and a nut 5 is welded on.

[0006] A long strip of baffle 4 is welded between the two fan-shaped baffles 2 to limit the rotation angle of the fan-shaped half-section baffle 3.

[0007] The fan-shaped half-section baffle 3 and the open steel plate 1 are connected by a hinge.

[0008] The upper end of the fan-shaped baffle 2 is provided with an insertion hole and a pin, and the fan-shaped half of the baffle 3 is equipped with a pin sleeve.

[0009] The three open steel plates 1 are connected as one unit, and are equipped with three openings and corresponding fan-shaped half-section cutting baffles 3 installation structures.

[0010] The beneficial effects of this utility model are: The installation process is simpler and more convenient, saving manpower and resources and improving end-sealing efficiency. All materials used are commercially available, and the finished device can be manufactured without extensive processing.

[0011] This novel end-sealing device can be precisely fixed using two long bolts, a simple, efficient, and secure process. During construction, the baffle at the filling port can be opened or closed as needed. This saves time on fixing and filling, improving end-sealing efficiency.

[0012] The fan-shaped section of the end-sealing device can be adjusted in angle along two fan-shaped baffles. After the concrete is poured, the baffles can be rotated to seal the concrete. The box girder end-sealing device is bolted to the existing bolt holes in the anchorage. This connection is more secure and convenient than before. The opening at the top of the device forms a loading area, preventing concrete from spilling and allowing it to be smoothly loaded into the anchorage using its own weight. This makes the entire end-sealing process more convenient, and the more secure and fitting connection between the device and the anchorage results in a better finished product and higher efficiency.

[0019] Example 1: like Figure 1A railway box girder end-sealing device includes an open steel plate 1, which is circular with a square opening at one end. Two fan-shaped baffles 2 are vertically welded to both sides of the square opening. Installation grooves are carved out on both sides of the bottom edge of the square opening. A fan-shaped half-section baffle 3 is installed on the opening, and the shape of the fan-shaped half-section baffle 3 is the same as the opening shape. The bottom ends of the fan-shaped half-section baffle 3 have extending shafts, which are placed in the installation grooves. The fan-shaped half-section baffle 3 is installed into the opening of the circular open steel plate 1. A stop block 6 is welded to the side of the installation groove where the fan-shaped baffles 2 are not welded. The front side of the installation groove is blocked by the two fan-shaped baffles 2, and the rear side of the installation groove is blocked by the stop block 6, thus sealing the two ends of the rotating shafts of the fan-shaped half-section baffle 3 within the installation groove. The two fan-shaped baffles 2 and the fan-shaped half-section baffle 3 form a baffle plus movable opening structure, controlling the opening and closing of the loading port. The fan-shaped baffles on both sides can be used to prevent concrete from spilling. A hole is made in the middle of the open steel plate 1 and a nut 5 is welded on. The device completely covers the anchor hole. Two small holes are made at the positions corresponding to the positions of the bolt holes in the anchor hole, extending outward. Nuts 5 are inserted and welded firmly to the circular open steel plate 1.

[0020] A long strip of baffle 4 is welded between the two fan-shaped baffles 2 to limit the rotation angle of the fan-shaped half-section baffle 3.

[0021] Furthermore, the upper end of the fan-shaped baffle 2 has two insertion holes and is equipped with pins, and the fan-shaped half of the baffle 3 is fitted with a pin sleeve, which can be used to restrict the baffle to different positions.

[0022] Example 2: like Figure 5 This embodiment adds a hinge structure to embodiment 1, and the fan-shaped half-section baffle 3 and the open steel plate 1 are connected by a hinge. Figure 3 and Figure 4 In this embodiment, the circular open steel plate 1 and the fan-shaped half-cutting baffle 3 are cut from the same circular plate. In order to ensure that there is no interference during rotation, more material is removed from the rotating shaft part at both ends of the fan-shaped half-cutting baffle 3, making it smaller than the size of the mounting groove.

[0023] Example 3: In this example, the three open steel plates 1 from Example 1 are connected into one piece, with the structure as follows: Figure 6 The three open steel plates 1 are connected as one, and are equipped with three openings and corresponding fan-shaped half-section cutting baffles 3 installation structures.

[0024] Example 4: This example is based on Example 2, where three open steel plates 1 are connected as one piece, with the structure as follows. Figure 7The three open steel plates 1 are connected as one unit, and are equipped with three openings and corresponding fan-shaped half-section cutting baffles 3 plus movable opening structures.
