DETAILED DESCRIPTION

[0025] It should be noted that the following detailed descriptions are all illustrative and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0026] Embodiment 1

[0027] This embodiment provides a road curve protection device, such as Figure 1-5 As shown, it includes a first rotating member 1; a first fastener 2; a first protective member 3 and a column 4; a second fastener 5; a second rotating member 6; and a second protective member 7. The first rotating member 1 and the second rotating member 6 are respectively installed on the upper half of the side of the column 4, and the lower half of the column 4 can be directly driven into the foundation by a hydraulic pile driver, or can be cast by hydraulic concrete.

[0028] The first rotating member 1 includes: a first clamp 10, a second clamp 11, and a connecting portion 9; the first clamp 10 and the second clamp 11 are circular opening structures, and connecting portions 9 are arranged on both sides of the openings. The connecting portion 9 is composed of two steel plates, and each steel plate is connected to the same side of the openings of the first clamp and the second clamp respectively; since the circular clamp is installed on the side of the column, the rotating member as a whole can rotate with the column as the axis.

[0029] The first rotating member 1 and the second rotating member 6 are arranged crosswise up and down. The crosswise arrangement means that the second clamps 11 of the two rotating members are respectively placed in the gap between the first clamp 10 and the second clamp 11 of the other rotating member. The specific cross structure diagram is shown in FIG. Figure 6 As shown, finally, the two rotating parts are sleeved on the upper half of the side of the column 4; the first rotating part 1 is connected to the first protective part 3 through the first fastener 2, the first protective part 3 and the second protective part 7 have the same structure, the protective part can be a steel plate or a high-strength polymer plate, and the cross-section can be processed into a C shape or an M shape to improve the strength of the protective part.

[0030] The first fastener 2 has the same structure as the second fastener 5 and may be a bolt and a nut; the first fastener 2 can not only install the protective part on the rotating part, but also adjust the tightness of the first rotating part 1 and the column 4 through the bolt and the nut; the opening structure reserves a certain gap for the connecting part 9 to tighten the first clamp 10 and the second clamp 11. After the connecting part 9 is tightened, the first clamp 10 and the second clamp 11 are in close contact with the column 4 to ensure the reliability of the installation.

[0031] The method for connecting and adjusting the second fastener 5 to the second rotating member 6 and the second protective member 7 is the same and will not be described in detail. The angle between the first rotating member 1 and the second rotating member 6 can be adjusted according to the actual road conditions.

[0032] In order to facilitate the processing of the rotating parts, the first clamp 10, the second clamp 11 and the connecting part 9 can be connected by welding, or they can be processed by directly bending the steel plate using a bending machine. The processing method can be flexibly selected during the specific construction process to minimize the complexity of the construction.

[0033] The connecting parts 9 of the first rotating member 1 and the second rotating member 6 are both provided with through holes 13, and the first fastener 2 can pass through the connecting hole 12 at the end of the first protective member 3 and the through hole 13 of the connecting part 9 to connect the first rotating member 1 and the first protective member 3 as a whole. Since the first rotating member 1 and the second rotating member 6 have the same structure, the connection method of the second rotating member 6 and the second protective member 7 is the same as the above steps. In addition, the first rotating member 1 and the second rotating member 6 are arranged crosswise up and down so that the first protective member 3 and the second protective member 7 are at the same height when installed, ensuring the overall aesthetics of the protective device.

[0034] The first protective member 3 and the second protective member 7 are made of steel or high-strength polymer. If the protective member is made of steel, it can be directly formed by rolling using a steel plate. If the protective member is made of a high-strength polymer, it can be formed by thermoplasticization + cooling using a mold. A connecting hole 12 is also provided at the end of the protective member to connect with the rotating member.

[0035] The column 4 is a steel pipe, preferably made of an anti-corrosion material such as stainless steel. A cover adapted to the diameter of the column 4 is arranged at the top of the column 4 to prevent water from accumulating inside the column 4 when it rains, thereby reducing the foundation strength.

[0036] Below the second rotating member 6, a blocking block 8 is provided on the side of the column 4, which can be connected to the column by welding; the setting of the blocking block 8 ensures that the protective parts on the entire road are at the same height after installation, ensuring a consistent appearance.

[0037] Installation steps:

[0038] In the construction section, the column is pressed into the ground below the surface by a pile driver or fixed by pouring concrete, the first rotating part and the second rotating part are crossed and all the hoops are ensured to be coaxial, all the hoops are inserted into the upper half of the column, and then the connecting hole of the first protective part is aligned with the through hole of the first rotating part, the first protective part and the first rotating part are connected by the first fastener bolt and the bolts and nuts are pre-tightened. The connection steps of the second rotating part and the second protective part are the same as the connection steps of the first rotating part and the first protective part, and they are not repeated here. After pre-tightening, the first rotating part and the second rotating part are rotated according to the actual situation of the curve. After the angle is adjusted appropriately, the bolts and nuts are finally tightened. At this time, the hoop of the rotating part fits tightly against the side of the column, and the protective part and the rotating part are also firmly connected.

[0039] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
