It is one of the main forms of track structure. It has the advantages of good elasticity, low price, easy replacement and maintenance, and good noise absorption.

[0003] At present, when laying ballasted track sleepers on a curve, the method usually adopted is: transporting the sleepers to the construction site, and then lifting and swinging them by machinery and manual labor. This method is not limited by the track laying base and site conditions, and is relatively flexible. The ballast can be pre-laid and the sleepers can be lifted and swung after the roadbed and bridge culvert are formed. However, when the above method is used to lay ballasted track sleepers on a curve, the curve laying of ballasted track sleepers requires precise positioning of the sleepers to ensure their use effect after laying; and the above laying process

[0004] It is difficult to effectively control the laying accuracy requirements, resulting in the entire laying process being subject to significant human interference factors, and it is impossible to achieve the sleeper spacing and squareness control when laying ballasted track with a small radius of 500mm-750mm, and the adjustment of the sleeper spacing and squareness during track fine-tuning after laying is completed; at the same time, after searching, a long rail pushing and laying device for curved sections disclosed in Patent No. CN215164222U can prevent overturning during the pushing process of laying long rails in curved sections when in use, reduce the occurrence of long rails colliding with sleeper shoulders, and solve the problem that the existing long rails are prone to overturning and damage to sleepers when being pushed and laid in curved sections; but it does not solve the problem of large human interference and difficulty in effectively controlling the accuracy of ballasted track sleepers during curved laying as mentioned above.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example 1: Please refer to Figure 1 , Figure 2 and Figure 3 The utility model provides a technical solution: a construction device for controlling the squareness of sleepers of a small radius ballasted track, comprising:

[0029] A mounting platform 1, wherein two support blocks 101 are fixedly connected to the bottom of the mounting platform 1, a mounting groove 102 is provided on the top of the mounting platform 1, and a slide groove connected to the mounting groove 102 is provided on the top of the mounting platform 1;

[0030] The driving mechanism 2 includes a template component 21 arranged inside the mounting groove 102, and an adjusting component 22 is arranged inside the slide groove. The adjusting component 22 cooperates with the template component 21 to be used for laying square curves of sleepers; the adjusting component 22 includes a connecting plate 2201 slidably connected to the inner wall of the slide groove, and a slide 2203 is slidably connected to the top of the mounting platform 1, and an adjusting screw 2204 is arranged on the top of the slide 2203, and the lower end of the adjusting screw 2204 passes through a thread and passes through the slide 2203 and is rotatably connected to the top of the connecting plate 2201; when in use, the height of the connecting plate 2201 can be adjusted by rotating the adjusting screw 2204 forward and reversely, and the setting of the slide 2203 can make the connecting plate 2201 slide on the inner wall of the slide groove and drive the adjusting screw 2204 to move synchronously through the slide 2203, thereby not affecting the movement of the connecting plate 2201.

[0031] Example 2: Please refer to Figure 2 , Figure 3 and Figure 4 The bottom of the connecting plate 2201 is fixedly connected with a connecting block 2207, and a sliding groove is passed through the lower end of the connecting block 2207. A clearance area 2208 is opened on one side of the connecting block 2207, and a baffle 2209 is arranged on the inner wall of the clearance area 2208. Two symmetrically distributed connecting rods 2205 are fixedly connected to the other side of the baffle 2209. The bottom of the connecting rod 2205 is fixedly connected with evenly distributed limit rods 2206. The top of the baffle 2209 is fixedly connected with a rotating shaft 2210. The upper end of the rotating shaft 2210 passes through the clearance area 2208 and is rotatably connected to the inner wall of the connecting block 2207. A torsion spring 2212 is fixedly connected to the surface of the rotating shaft 2210, and the other end of the torsion spring 2212 is fixedly connected to the inner wall of the connecting block 2207. When in use:

[0032] (1) The square of the sleeper to be adjusted is placed below the baffle plate 2209 and two adjacent connecting rods 2205, and the connecting plate 2201 is driven downward by the adjusting screw 2204, so that the connecting block 2207 is moved downward synchronously. In this process, the limiting rods 2206 can be located on both sides of the square of the sleeper, so that the position of the sleeper can be limited by the limiting rods 2206 when the baffle plate 2209 is used to push the sleeper to be square.

[0033] (2) By moving the connecting block 2207, it can slide on the inner wall of the slide groove through the connecting plate 2201, and in this process, it can drive the baffle plate 2209 to move synchronously. The torsion spring 2212 is set to limit the position of the baffle plate 2209 under normal conditions, so that it can push the rail sleeper to move in the direction of the installation groove 102 during the process of driving the baffle plate 2209 to move.

[0034] Example 3: Please refer to Figure 2 , Figure 3 and Figure 4The adjustment assembly 22 further includes a hydraulic push rod 2202 disposed inside the mounting platform 1, the output shaft of the hydraulic push rod 2202 passes through the mounting platform 1 and is fixedly connected to a driving block 2211, the cross-sectional shape of the driving block 2211 is "T"-shaped, a driving groove is provided on one side of the connecting plate 2201 away from the connecting rod 2205, and the driving block 2211 is slidably connected to the inner wall of the driving groove;

[0035] By starting the hydraulic push rod 2202, the driving block 2211 can be driven to move the connecting block 2207, thereby achieving the effect of adjusting the square position of the sleeper. There is no need for staff to push it, and the operation is simple.

[0036] Example 4: Please refer to Figure 2 , Figure 3 and Figure 4 The template assembly 21 includes a template body 2101 arranged inside the installation groove 102, one side of the template body 2101 is arranged in a curved surface, and the other side of the template body 2101 is fixedly connected to a limiting block 2102, and the inner wall of the installation groove 102 is provided with a limiting groove matching the limiting block 2102; when in use, the template body 2101 can be replaced according to actual needs, so as to realize the installation of template bodies 2101 with different curvatures. During the installation process, the limiting block 2102 is aligned with the limiting groove and the template body 2101 is placed. After the template body 2101 is in place, the hydraulic push rod 2202 can be started to drive the sleeper to move in the direction of the template body 2101, and the end of the sleeper that is prevented from moving along the curved surface of the template body 2101 away from the baffle 2209 can be deviated along the curved surface. In this process, the limit rod 2206 can be pushed to make the connecting rod 2205 drive the baffle 2209 to rotate with the rotating shaft 2210 as the center, thereby not affecting the displacement of the template body 2101 affected by the curved surface. At the same time, the torsion spring 2212 can be tightened to facilitate the subsequent reset of the limit rod 2206 after separation from the sleeper.

[0037] The construction process of the construction equipment for controlling the squareness of the sleepers of the small radius ballasted track as described in the above embodiments 1 to 4 is as follows:

[0038] When the utility model is in use, the template body 2101 of the corresponding curvature is installed inside the installation groove 102 through the limit block 2102 and the limit groove according to the actual situation, and the rail sleeper that needs to be adjusted is placed below the baffle 2209 and the two adjacent connecting rods 2205, and the connecting plate 2201 is driven to move downward by adjusting the screw rod 2204, so that the connecting block 2207 moves downward synchronously. In this process, the limit rod 2206 can be located on both sides of the rail sleeper square, so that when the baffle 2209 pushes the rail sleeper square, its position is limited by the limit rod 2206, and the rail sleeper can be driven to move in the direction of the template body 2101 by starting the hydraulic push rod 2202. The movement prevents the end of the sleeper away from the baffle 2209 from being able to deviate along the curved surface after contacting the curved surface of the template body 2101. During this process, the limit rod 2206 can be pushed to make the connecting rod 2205 drive the baffle 2209 to rotate with the rotating shaft 2210 as the center, thereby not affecting the deviation of the template body 2101 affected by the curved surface. At the same time, the torsion spring 2212 is tightened to facilitate the subsequent reset of the limit rod 2206 after the square is separated from the sleeper. After the adjustment is completed, the adjusting screw 2204 is rotated in the opposite direction to make the connecting plate 2201 move up, which can drive the connecting block 2207 to move up synchronously, so that the limit rod 2206 is separated from the square of the sleeper, thereby completing the adjustment of the square position of the sleeper.
