The main function of the roadbed is to provide the necessary conditions for the laying of the track or road surface and the operation of trains or vehicles, and to bear the static and dynamic loads of the track and locomotives or the road surface and traffic loads, while transferring and spreading the loads to the depths of the foundation. However, during the construction of existing roadbeds, it is inconvenient to fit the sides of the roadbed piles according to their length and width, resulting in poor adaptability, which affects the support effect and makes them prone to tipping over. Therefore, in order to avoid the above-mentioned technical problems, it is indeed necessary to provide a side fixing mechanism for roadbed construction to overcome the defects of the existing technology. Utility Model Content

[0003] This utility model provides a side fixing mechanism for roadbed construction, which can effectively solve the problems mentioned in the background art, such as the inconvenience of fitting the side of the roadbed pile according to its length and width, poor adaptability, affecting the support effect, and easy to cause tilting.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a side fixing mechanism for roadbed construction, comprising two fixed horizontal piles, and a length adjustment mechanism is provided between the two fixed horizontal piles. The length adjustment mechanism includes an internal threaded cylinder, a bidirectional threaded rod, an adjusting groove, an extension reinforcing plate, a positioning frame, a shifting sleeve, and an anti-deviation buckle plate. Both of the fixed horizontal piles have internally threaded cylinders that are snapped into them, and both of the internally threaded cylinders have bidirectional threaded rods that are threadedly connected to them. Both of the two fixed horizontal piles are provided with adjustment grooves at the top and bottom. An extension reinforcement plate is movably connected inside the adjustment groove, and a positioning frame is engaged between the two opposite extension reinforcement plates. A toggle sleeve is engaged at the position inside the positioning frame on the outside of the bidirectional threaded rod. Both of the extended reinforcing plates located on the same side have anti-deviation buckles attached to one end at equal intervals.

[0005] Preferably, the fixed horizontal stake is provided with a side limiting and folding mechanism, which includes a rotating groove, a rotating block, an adjusting shaft seat, an adjusting push rod, a C-shaped limiting frame, an anti-deviation groove, a limiting slider, and a side clamping plate. One end of the fixed horizontal pile is provided with a rotating groove, and a rotating block is rotatably connected inside the rotating groove. One end of the rotating block is engaged with an adjusting shaft seat, and an adjusting push rod is threadedly connected inside the adjusting shaft seat. Both ends of the adjusting push rod are rotatably connected to C-shaped limit frames, and one end of the C-shaped limit frame is provided with an anti-deviation groove. One end of the adjusting shaft seat is engaged with a limit slider at the position inside the anti-deviation groove. One end of the C-shaped limiting frame is clamped to a side clamp.

[0006] Preferably, the threads at both ends of the bidirectional threaded rod rotate in opposite directions, anti-slip textures are evenly distributed at the middle position of the outer side of the actuating sleeve, and one end of the anti-deviation buckle plate is attached to one end of the fixed horizontal post.

[0007] Preferably, one end of the adjusting push rod passes through one end of the C-shaped limiting frame, and a knob is engaged with one end of the adjusting push rod; the outer side of the limiting slider is slidably connected to the inner wall of the anti-deviation groove.

[0010] Compared with the prior art, the advantages of this utility model are: the structure of this utility model is scientific and reasonable, and it is safe and convenient to use. 1. Equipped with a length adjustment mechanism, the bidirectional threaded rod rotates inside the inner threaded cylinder by moving the sleeve. The positioning frame, extension reinforcement plate, and adjustment groove work together to limit the fixed cross pile, preventing it from rotating. This forces the bidirectional threaded rod to push the two inner threaded cylinders to move synchronously in opposite directions, thereby pushing the two fixed cross piles to move. This adjusts the distance between the two fixed cross piles, making it easier to adjust the distance between the ends of the two fixed cross piles according to the length of the roadbed. It also changes the clamping position of the two side clamps, allowing them to fit roadbeds of different lengths, improving adaptability and ensuring the fixing effect.

[0011] 2. Equipped with a side limiting and folding mechanism, the C-shaped limiting frame moves along the inside of the adjusting shaft seat by rotating the adjusting push rod, and the side clamp moves together. The extension length of the side clamp is adjusted according to the width of the roadbed, which facilitates the fixing of the cross stake and the roadbed, further improving the fixing effect. When not in use, the adjusting shaft seat, C-shaped limiting frame and side clamp can be easily rotated and folded by the cooperation of the rotating groove and rotating block, so that they are parallel to the fixing cross stake, reducing the area and making it easy to carry and store.

[0012] 3. It is equipped with a positioning baffle, positioning pin and positioning screw hole. The positioning baffle is fixed by the cooperation of the positioning pin and positioning screw hole, thereby improving the stability of the adjusting axle seat, ensuring the perpendicularity with the fixed horizontal pile, and increasing the fixing effect on the side of the roadbed.

Detailed Implementation

[0015] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0016] Example: Figure 1-4 As shown, this utility model provides a technical solution, a side fixing mechanism for roadbed construction, including two fixed horizontal piles 1, and a length adjustment mechanism 2 is provided between the two fixed horizontal piles 1. The length adjustment mechanism 2 includes an internal threaded cylinder 201, a bidirectional threaded rod 202, an adjusting slide 203, an extension reinforcing plate 204, a positioning frame 205, a moving sleeve 206, and an anti-deviation buckle plate 207. Both fixed horizontal piles 1 have internally threaded cylinders 201 that are snapped into them, and both internally threaded cylinders 201 have bidirectional threaded rods 202 that are threadedly connected to them. The top and bottom of the two fixed horizontal piles 1 are provided with adjustment grooves 203. The adjustment grooves 203 are movably connected with extension reinforcing plates 204. The two opposite extension reinforcing plates 204 are locked with positioning frames 205. The outside of the bidirectional threaded rod 202 is locked with a toggle sleeve 206 corresponding to the position inside the positioning frame 205. Two extended reinforcing plates 204 located on the same side are each equidistantly clamped with anti-deviation buckle plates 207. In order to facilitate the adjustment of the distance between the two fixed horizontal piles 1, the threads at both ends of the two-way threaded rod 202 rotate in opposite directions. Anti-slip textures are evenly provided at the middle position of the outer side of the sliding sleeve 206. One end of the anti-deviation buckle plate 207 is attached to one end of the fixed horizontal pile 1. The fixed horizontal pile 1 is equipped with a side limiting and folding mechanism 3, which includes a rotating groove 301, a rotating block 302, an adjusting shaft seat 303, an adjusting push rod 304, a C-shaped limiting frame 305, an anti-deviation groove 306, a limiting slider 307, and a side clamping plate 308. One end of the fixed horizontal pile 1 is provided with a rotating groove 301. A rotating block 302 is rotatably connected inside the rotating groove 301. One end of the rotating block 302 is snapped with an adjusting shaft seat 303. An adjusting push rod 304 is threadedly connected inside the adjusting shaft seat 303. Both ends of the adjusting push rod 304 are rotatably connected to C-shaped limit frames 305, and one end of the C-shaped limit frame 305 is provided with an anti-deviation groove 306. One end of the adjusting shaft seat 303 is engaged with a limit slider 307 at the position inside the anti-deviation groove 306. One end of the C-shaped limiting frame 305 is clamped to a side clamp 308. In order to facilitate the adjustment of the position of the side clamp 308, one end of the adjusting push rod 304 passes through one end of the C-shaped limiting frame 305, and one end of the adjusting push rod 304 is clamped to a knob. The outer side of the limiting slider 307 is slidably connected to the inner wall of the anti-deviation groove 306. One end of the adjusting shaft seat 303 is fitted with a positioning baffle 4. One end of the positioning baffle 4 is connected to a positioning pin 5 at equal intervals by a thread, and one end of the fixed horizontal post 1 is provided with positioning screw holes 6 at equal intervals. In order to improve the stability of the adjusting shaft seat 303, one end of the positioning baffle 4 is in contact with one end of the fixed horizontal post 1, and one end of the positioning pin 5 is embedded in the positioning screw hole 6.

[0017] The working principle and usage process of this utility model are as follows: First, during use, by moving the sleeve 206, the bidirectional threaded rod 202 is driven to rotate inside the inner threaded cylinder 201. With the cooperation of the positioning frame 205, the extension reinforcement plate 204 and the adjusting slide 203, the fixed horizontal pile 1 is limited to prevent the fixed horizontal pile 1 from rotating. This forces the bidirectional threaded rod 202 to push the two inner threaded cylinders 201 to move synchronously in opposite directions, thereby pushing the two fixed horizontal piles 1 to move and adjusting the distance between the two fixed horizontal piles 1. This makes it easier to adjust the distance between the ends of the two fixed horizontal piles 1 according to the length of the roadbed, thus improving adaptability. Next, by adjusting the fixed cross post 1, the positions of the two side clamps 308 are changed, allowing the side clamps 308 to fit with roadbeds of different lengths, thus improving adaptability. In addition, rotating the adjusting push rod 304 moves the C-shaped limiting frame 305 along the inside of the adjusting shaft seat 303, and moves the side clamps 308 together. The extension length of the side clamps 308 is adjusted according to the width of the roadbed, making it easier for the fixed cross post 1 to fit with the roadbed, further improving the fixing effect. When not in use, the rotating groove 301 and the rotating block 302 cooperate to easily rotate and fold the adjusting shaft seat 303, the C-shaped limiting frame 305 and the side clamps 308, making them parallel to the fixed cross post 1, reducing the occupied area and making them easy to carry and store. Finally, when the adjusting shaft seat 303 and the C-shaped limiting frame 305 rotate open, the positioning baffle 4 is brought into contact with the fixed horizontal pile 1, and the positioning baffle 4 is fixed by the cooperation of the positioning pin 5 and the positioning screw hole 6, thereby improving the stability of the adjusting shaft seat 303, ensuring the vertical effect with the fixed horizontal pile 1, and increasing the fixing effect on the side of the roadbed.
