Description
Technical Field
[0001] The utility model relates to the technical field of fixed brackets, in particular to a single-tube fixed bracket for an underground section of urban rail transit. Background Art
[0002] With the rapid development of urbanization, the construction of urban rail transit systems has received increasing attention. Rail transit tools such as subways and light rails are popular among urban residents because of their punctuality, speed and large capacity. However, in the construction of urban rail transit, the layout and fixation of wire pipes in underground sections is a technical problem. Wire pipes, such as lighting threading pipes, evacuation indication threading pipes, FAS (fire alarm system) threading pipes, etc., are important facilities in the underground sections of urban rail transit. These wire pipes carry important lines such as electricity, signals and data, which are crucial to the safe and stable operation of urban rail transit. In traditional urban rail transit construction, special brackets for wire pipes are usually installed on the side walls of tunnels. The single threading pipe is generally fixed to these special brackets by U-shaped clamps and bolts. However, this traditional installation method has many disadvantages.
[0003] The current construction efficiency is low. Since bolts and U-shaped clamps are needed for fixing, the position needs to be repeatedly adjusted and the bolts need to be tightened during the installation process, which undoubtedly increases the difficulty and time cost of construction. Secondly, the traditional installation method is not convenient for the installation and adjustment of the wire pipe during construction. Once the wire pipe needs to be adjusted or replaced, it is often necessary to loosen the bolts, adjust the U-shaped clamp, and then retighten the bolts. The process is cumbersome and time-consuming. Moreover, the tightening state of the bolts is crucial to operational safety. If the bolts are not tightened or become loose later, the wire pipe may fall off or shift, which will have a serious impact on the operational safety of urban rail transit. Utility Model Content
[0004] The purpose of the utility model is to make up for the deficiencies of the prior art and to provide a single-tube fixing bracket for an underground section of urban rail transit.

[0006] Preferably, the adjustment mechanism comprises a circular rotating cylinder and a circular sliding rod, and the circular rotating cylinder is fixedly connected to the bottom surface of the elastic bite pipe clamp.
[0007] Preferably, a circular rotating block is rotatably connected inside the circular rotating drum, and an adjusting screw is fixedly connected to the bottom surface of the circular rotating block.

[0020] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.
[0021] See also Figure 1 to Figure 3 A single-tube fixed bracket for an underground section of urban rail transit comprises an angle steel bracket 1, a bolt mounting hole 2 is opened inside the angle steel bracket 1, an elastic bite pipe clamp 3 is arranged above the angle steel bracket 1, two anti-slip limit strips 4 are fixedly connected to the inner side of the elastic bite pipe clamp 3, and an adjustment mechanism 5 is arranged on the bottom surface of the elastic bite pipe clamp 3.
[0022] The adjustment mechanism 5 includes a circular rotating cylinder 501 and a circular sliding rod 505. The circular rotating cylinder 501 is fixedly connected to the bottom surface of the elastic bite pipe clamp 3. The circular rotating block 502 is rotatably connected inside the circular rotating cylinder 501, and the bottom surface of the circular rotating block 502 is fixedly connected to the adjusting screw 503. The adjusting screw 503 is rotatably connected to the inside of the circular rotating cylinder 501, and the outer surface of the adjusting screw 503 is threadedly connected to the threaded cylinder 504. The threaded cylinder 504 is fixedly connected to the inside of the angle steel bracket 1, and the circular sliding rod 505 is fixedly connected to the bottom surface of the elastic bite pipe clamp 3. One end of the circular sliding rod 505 away from the elastic bite pipe clamp 3 is fixedly connected to the limiting circular plate 506, and the circular sliding rod 505 is slidably connected to the inside of the angle steel bracket 1.
[0023] The adjusting mechanism 5 is used to adjust the height of the elastic bite pipe clamp 3 to adapt to the wire pipes in different installation positions. The adjusting mechanism 5 includes the following parts: a circular rotating drum 501: This is a cylindrical cylinder, which is fixedly connected to the bottom surface of the elastic bite pipe clamp 3. The circular rotating drum 501 is made of a lightweight and high-strength aluminum alloy material to reduce the weight of the entire fixed bracket while ensuring mechanical strength.
[0024] The circular rotating block 502 is a component that can rotate inside the circular rotating drum 501. The circular rotating block 502 is made of hard alloy with good wear resistance to ensure its stability and durability in long-term use.
[0025] The adjusting screw 503 is a rod-shaped component with threads, and the height of the elastic bite pipe clamp 3 can be adjusted by rotating it. The adjusting screw 503 is made of high-strength steel to withstand the torque and shear force during the adjustment process.
[0026] The threaded cylinder 504 is a cylindrical component with threads inside, and cooperates with the adjusting screw 503 to achieve height adjustment. The threaded cylinder 504 is made of hard alloy with good wear resistance to ensure the durability and adjustment accuracy of the threads.
[0027] The circular slide bar 505 is a smooth rod-shaped component used to guide the elastic bite pipe clamp 3 to move in the vertical direction. The circular slide bar 505 is made of cemented carbide or stainless steel to improve its wear resistance and corrosion resistance and ensure smoothness and stability of sliding.
[0028] The limiting circular plate 506 is a circular plate located at the bottom of the circular slide rod 505, which is used to limit the movement range of the elastic bite pipe clamp 3. The limiting circular plate 506 is made of hard plastic or metal to improve its durability and stability, and effectively limit the movement range of the elastic bite pipe clamp 3.
[0029] By fixing the angle steel bracket 1 on the tunnel side wall through the bolt mounting hole 2, next, the wire pipe to be fixed is placed in the elastic bite pipe clamp 3. Since the elastic bite pipe clamp 3 has an elastic design, it can tightly hold the wire pipe to prevent it from moving or falling off. At the same time, the anti-drop limit clip 4 also plays a further stabilizing role.
[0030] When the position of the wire tube needs to be adjusted, the circular rotating cylinder 501 can be rotated, and the adjusting screw 503 can be driven to rotate in the threaded cylinder 504 through the circular rotating block 502, so as to realize the up and down movement of the elastic bite pipe clamp 3, and the circular sliding rod 505 slides inside the angle steel bracket 1, ensuring the smoothness and accuracy of the movement of the elastic bite pipe clamp 3, and the limiting circular plate 506 prevents the circular sliding rod 505 from escaping from the angle steel bracket 1, thereby enhancing the safety of the entire fixed bracket.
[0031] The angle bracket 1 is made of high-strength steel and is responsible for providing stable support, ensuring mechanical strength and durability. It can bear the weight of the wire conduit and its accessories and maintain stability during installation and use. The size can be customized according to the actual application scenario to meet the installation requirements of wire conduits of different diameters.
[0032] The bolt mounting hole 2 is opened on the angle steel bracket 1, and the size of the hole can be customized according to the actual application scenario to meet the installation requirements of wire pipes of different diameters. The elastic bite pipe clamp 3 is an elastic clamp used to fix the threading pipe. By using wear-resistant and corrosion-resistant high-strength spring steel material, it can ensure the service life and tightening effect. The size can be customized according to the actual application scenario to meet the installation requirements of wire pipes of different diameters. The anti-drop limit card strip 4 is located on the inner side of the elastic bite pipe clamp 3 and is made of hard plastic or metal to increase the stability of the wire pipe and effectively prevent it from falling off or shifting.
[0033] The elastic bite pipe clamp 3 can tightly hold the wire pipe to prevent the wire pipe from moving or falling off. The inner side of the elastic bite pipe clamp 3 is also fixedly connected with two anti-drop limit clamp strips 4, which further enhances the stability of the wire pipe.
[0034] The angle steel bracket 1 can be 90 degrees or 100 degrees. Figure 4 The 100° angle bracket is shown and can be set up according to specific installation requirements.
[0035] Working principle: When the device is in use, first fix the angle steel bracket 1 on the side wall of the tunnel through the bolt mounting hole 2, and then place the wire pipe to be fixed in the elastic bite pipe clamp 3. Since the elastic bite pipe clamp 3 has an elastic design, it can tightly hold the wire pipe to prevent it from moving or falling off. At the same time, the anti-drop limit clamp strip 4 also plays a further stabilizing role. When the device needs to adjust the position of the wire pipe, the circular rotating cylinder 501 can be rotated, and the adjusting screw 503 is driven to rotate in the threaded cylinder 504 through the circular rotating block 502, so as to realize the up and down movement of the elastic bite pipe clamp 3, and the circular slide bar 505 slides inside the angle steel bracket 1, ensuring the smoothness and accuracy of the movement of the elastic bite pipe clamp 3, and the limiting circular plate 506 prevents the circular slide bar 505 from falling out of the angle steel bracket 1, thereby enhancing the safety of the entire fixed bracket.
