Description

Technical Field

[0001] This utility model relates to the field of railway construction technology, specifically a railway track laying support device for railway track transportation construction. Background Technology

[0002] Tracks typically consist of two parallel steel rails, which are fixed on sleepers. Below the sleepers is the ballast. Steel rails can withstand greater weight than other materials.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN210315089U) discloses a waterproof display and control instrument, including a mounting base, a sleeper housed within the mounting base, a rail mounted on the sleeper, and a sealing ring on the inner wall of the mounting base. The mounting base is connected to the rail via a first bolt passing through the sealing ring. A support plate is housed within the mounting base, and the sleeper is supported on the support plate. This rail laying support device for railway track construction, through the fixing of the sleeper to the mounting base, allows the sleeper to be supported and positioned by the mounting base, improving the stability of the sleeper. The mounting base can be positioned vertically by inserting square rods on both sides of the internal box into the ground, and can be positioned horizontally by the internal box being placed in a ground groove, thereby improving the overall structural stability.

[0004] Although the aforementioned patented mounting base can be positioned vertically by inserting square rods on both sides of the built-in box into the ground, and can be positioned horizontally by placing the built-in box in the ground groove, thereby improving the stability of the overall structure, the above technology makes it difficult to adjust the width of the rail laying support device on both sides during use. In the laying of rails of different widths, construction workers need to frequently change rail laying support devices of different specifications, thus wasting a lot of manpower and time costs and reducing the construction efficiency of construction workers.

[0005] Therefore, this utility model provides a rail laying support device for railway track construction to solve the above problems. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] This utility model provides a rail laying support device for railway track construction, such as... Figures 1 to 5 As shown, it includes an embedded box 1, a rectangular frame 2 is fixedly installed on the upper surface of the embedded box 1, iron pillow blocks 3 are slidably connected to both sides inside the rectangular frame 2, and an adjustment component 4 is provided on the surface of the embedded box 1.

[0030] The adjusting assembly 4 includes a first sliding groove formed on the inner side wall of the iron pillow block 3. A double-acting screw 401 is rotatably connected to the upper surface of the embedded box 1 via a support plate. Fixing plates are fixedly installed on the inner side walls of the first sliding grooves on both sides. The double-acting screw 401 is threaded through the inner side of the fixing plates on both sides. A rotating rod 402 is rotatably connected to the surface of the rectangular frame 2. A bevel gear 403 is fixedly installed at the bottom of the rotating rod 402 and at the middle of the outer surface of the double-acting screw 401. The bevel gears 403 on both sides mesh with each other. A cylindrical groove is formed inside the rotating rod 402. A sliding column 404 is slidably connected inside the cylindrical groove. The bottom of the sliding column 404 is fixedly installed... A limiting spring 405 is installed and fixedly mounted on the inner bottom wall of the cylindrical groove. A pressure rod 406 is fixedly mounted on the top of the sliding column 404. Several second sliding grooves are opened on the outer surface of the rotating rod 402. An annular plate 407 is fixedly mounted on the outer surface of the sliding column 404 by a locking block. The locking block is slidably connected to the inside of the second sliding groove. Limiting columns 408 are arranged in annular array on the upper surface of the annular plate 407. Limiting holes are opened on the inner top wall of the rectangular frame 2. The limiting columns 408 are adapted to the limiting holes. An insert rod 409 is slidably connected through the outer surface of the pressure rod 406 and the rotating rod 402. One end of the insert rod 409 is threadedly connected to a limiting nut.

[0031] When it is necessary to adjust the distance between the iron pillow blocks 3 on both sides, the operator first removes the limiting nut on the surface of the insertion rod 409 to prevent the pressure rod 406 from sliding inside the rotating rod 402 when not in use. Then, the pressure rod 406 drives the sliding column 404 to slide downward inside the rotating rod 402. The sliding column 404 drives the annular plate 407 to move synchronously through the locking block. During the movement, the sliding column 404 presses the lower limiting spring 405, and the annular plate 407 drives the upper limiting column 408 to disengage from the limiting hole. At this time, the rotating rod 402 is in a rotating state. The rotating rod 402 drives the bottom bevel gear 403 to rotate, which in turn drives the meshing bevel gear 403 below and the internal double-acting screw 401 to rotate. The double-acting screw 401 drives the fixing plate and the iron sleeper block 3 to slide on the surface of the embedded box 1. The iron sleeper block 3 drives the upper rail body 5 to move synchronously. Thus, when laying rails of different widths is a heavy task, it is not necessary to frequently change rail support devices of different width specifications, thereby reducing manpower and time costs, alleviating the company's construction costs and improving the construction efficiency of workers.

[0032] The upper surface of the iron sleeper block 3 is bolted with a rail body 5, and the two sides of the embedded box 1 are slidably connected with mounting plates 6, which are fixedly connected to the iron sleeper block 3 by bolts.

[0033] During the sliding process, the iron sleeper block 3 drives the upper rail body 5 to move synchronously. The mounting plate 6 is connected to the iron sleeper block 3 by bolts. The iron sleeper block 3 will drive the mounting plate 6 to move synchronously. The mounting plate 6 slides outward or inward inside the embedded box 1 to ensure the stability of the iron sleeper block 3 when adjusting its width.

[0034] Several positioning rods 7 are slidably connected to both sides of the iron pillow block 3. A sliding plate 8 is fixedly installed at one end of each positioning rod 7. A support rod 9 is rotatably connected to the side surface of the sliding plate 8 through a hinge seat. A lower pressure plate is rotatably connected to the other end of the support rod 9 through a hinge seat. A column 10 is fixedly installed on the upper surface of the lower pressure plate. The column 10 is slidably connected to the surface of the embedded box 1 and the rectangular frame 2. A top plate 11 is fixedly installed on the top of the two columns 10. A through hole is opened on the surface of the top plate 11. A locking rod is fixedly installed on both sides of the inner sidewall of the embedded box 1. A permanent magnet 12 is fixedly installed at one end of the locking rod and on the outer surface of the column 10. The permanent magnets 12 on the upper and lower sides attract each other. A guide post is slidably connected to both sides of the sliding plate 8. A return spring 13 is fixedly installed on the side surface of the sliding plate 8. The other end of the return spring 13 is fixedly installed on the outer surface of the guide post. The magnetic force of the permanent magnet 12 is much greater than the elastic force of the return spring 13.

[0035] Workers first dig a groove for embedding, then place the embedding box 1 in the groove, and then press the top plate 11 down. The top plate 11 drives the column 10 to slide down, the column 10 drives the lower pressure plate to slide down, and the lower pressure plate drives the two side support rods 9 to move. The support rods 9 drive the two side sliding plates 8 to slide on the outer surface of the guide column. When the sliding plates 8 slide, the two side return springs 13 are stretched and deformed. The sliding plates 8 drive the positioning rods 7 to insert into the soil on both sides, ensuring the stability of the embedding box 1 during installation. During the sliding process, the permanent magnets 12 on the surface of the column 10 are magnetically attracted and connected to the permanent magnets 12 below, thereby limiting the position of the column 10. When disassembly is required, the top plate 11 is pulled upward forcefully, so that the permanent magnets 12 on the upper and lower sides are removed from the range of magnetic attraction. Then, the return force of the return springs 13 assists the workers in the disassembly operation, improving the workers' work efficiency.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
