Description

Technical Field

[0001] The invention belongs to the technical field of track structures, and in particular relates to an assembled track structure. Background Art

[0002] Ballastless track refers to a track structure that uses concrete, asphalt mixture and other integral foundations to replace the granular gravel roadbed. It is also called ballastless track and is the most advanced track technology in the world today. Compared with ballasted track, it has the advantages of good smoothness, good stability, long service life and good durability. For example, the invention patent with publication number CN108914714A provides an assembled sleeper plate or track plate ballastless track structure and assembly method, which is provided by a plurality of prefabricated sleeper plates or prefabricated track plates arranged longitudinally at intervals on the lower foundation of the track and connected accordingly, a longitudinal connector is arranged between two adjacent plates, and concrete is poured in the connection area to form an assembled integral structure of the track plate; and a limiting component can be provided as needed in the longitudinal connection area, and concrete is poured on the limiting component, so that each sleeper plate and the lower foundation of the track form an integral structure, thereby effectively realizing the connection and limiting of each sleeper plate. When assembling the ballastless track of this structure, it is necessary to use an alignment measuring device to measure whether the prefabricated track plate and the lower track foundation are aligned, and the prefabricated track plate needs to be fixed by a fixing device. It is usually necessary to set multiple pads between the prefabricated track plate and the lower track foundation to form a space for pouring concrete between the prefabricated track plate and the lower track foundation. The need to frequently use measuring equipment and fixing devices affects the assembly efficiency. During the alignment process, because the pads are not fixed, they are easily pushed during the process of adjusting the position of the prefabricated track plate, and it takes time to adjust to the initial position. In addition, due to the flatness problem of the lower track foundation, the use of pads of the same height will affect the smoothness of the track, so it is necessary to make improvements. Summary of the invention

[0003] In order to solve the above-mentioned defects of the prior art, the present application provides an assembled track structure, in which the fixing holes on the prefabricated track plate can be inserted into the first fixing column to complete the alignment, and after the support seat is connected to the first guide column, there is no need to adjust the position during subsequent assembly, which can effectively improve the assembly efficiency.

[0004] In order to achieve the above object, the present invention adopts the following technologies: An assembled track structure, comprising: A base, with a plurality of first guide columns arranged in an array along the length direction on both sides of the top; A plurality of pairs of support seats are arranged in an array along the length direction of the base, and the number of the pairs of support seats is the same as the number of the first guide pillars. The support seats are provided with a plurality of vertical through holes, and the plurality of first guide pillars are respectively inserted into the vertical through holes of the plurality of support seats. Two groups of first fixing pillars are provided on the top of the support seats along the length direction of the base; A plurality of prefabricated track plates are laid on the support seat along the length direction of the base, and the bottom of the prefabricated track plates are provided with four groups of fixing holes in a rectangular array, and the four groups of fixing holes at the bottom of each prefabricated track plate are respectively connected to the four groups of first fixing columns facing inward on the two adjacent pairs of support seats; A pair of steel rails are arranged on both sides of the top of the prefabricated track slab.

[0005] Furthermore, each group of first guide columns is four in number and arranged in a rectangular array. The support seat includes a rectangular block with a hollow interior. Four vertical through holes are opened in a rectangular array on the top of the rectangular block. A pair of connecting blocks are vertically provided at both ends of the rectangular block, and a first fixing column is provided on the connecting block.

[0006] Furthermore, both ends of the bottom of the prefabricated track plate have symmetrical first inclined surfaces, a support block is provided between each pair of connecting blocks, and the top of the support block has a second inclined surface matching the first inclined surface, which is used to cooperate with the first inclined surface to support the prefabricated track plate, and the support block has a threaded hole at one end facing the rectangular block, and connecting holes are provided at both ends of the rectangular block, and adjusting screws are rotatably connected in the connecting holes, and the adjusting screws are threadedly connected in the threaded holes.

[0007] Furthermore, the adjusting screw includes a screw body and a retaining ring, wherein the retaining ring is arranged outside the screw body, and when the screw rod of the screw body is completely inserted into the connecting hole, the retaining ring abuts against the side of the rectangular block facing the supporting block.

[0008] Furthermore, the height of the top of the first guide column is greater than the height of the top of the support seat, and a pair of first notches are symmetrically opened at both ends of the prefabricated track plate to accommodate the first guide column.

DETAILED DESCRIPTION

[0025] To make the objectives, technical solutions and advantages of the embodiments of the present invention more clear, the implementation modes of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] The present application embodiment provides an assembled track structure, such as Figure 1-Figure 8 As shown, it includes a base 1, a support seat 2, a prefabricated track plate 3, a rail 4, etc.

[0027] Specifically, both sides of the top of the base 1 are provided with multiple groups of first guide columns 101 in an array along the length direction. The first guide columns 101 can be pre-buried before the base 1 is cast to form an integral structure with the base 1; the support seats 2 are arranged in multiple pairs in an array along the length direction of the base 1, and the number of support seats 2 is the same as the number of groups of first guide columns 101. Multiple vertical through holes 201 are opened on the support seats 2, and multiple groups of first guide columns 101 are respectively penetrated in the vertical through holes 201 of multiple support seats 2, and two groups of first fixing columns 206 are arranged on the top of the support seat 2 along the length direction of the base 1; multiple prefabricated track plates 3 are laid on the support seats 2 along the length direction of the base 1, and the bottom of the prefabricated track plates 3 is provided with four groups of fixing holes 301 in a rectangular array, and the four groups of fixing holes 301 at the bottom of each prefabricated track plate 3 are respectively connected to the four groups of first fixing columns 206 facing inward on the two adjacent pairs of support seats 2; the rails 4 are a pair and are arranged on both sides of the top of the prefabricated track plates 3.

[0028] During the assembly process, the support seat 2 is first connected to the first guide column 101 on the base 1 through the vertical through hole 201, and then the four groups of fixing holes 301 at the bottom of the prefabricated track plate 3 are aligned with the four groups of first fixing columns 206 facing inward of the two adjacent pairs of support seats 2, and the prefabricated track plate 3 is lowered onto the support seat 2 to complete the alignment. At this time, the first guide column 101 can limit the movement of the support seat 2, and the first fixing column 206 can limit the movement of the prefabricated track plate 3. After pouring concrete between the base 1 and the prefabricated track plate 3, the rail 4 is installed on the prefabricated track plate 3 to complete the assembly.

[0029] Preferably, see Figure 2, the height of the top of the first guide column 101 is greater than the height of the top of the support seat 2, and a pair of first notches 303 are symmetrically opened at both ends of the prefabricated track plate 3 to accommodate the first guide column 101. After concrete is injected into the first notch 303, the first guide column 101 and the concrete can form an integral structure, thereby improving the stability of the prefabricated track plate 3 after installation. Further preferably, a second fixing column 306 is provided in the first notch 303, and the length direction of the second fixing column 306 is parallel to the length direction of the base 1. Specifically, the second fixing column 306 can be embedded when the prefabricated track plate 3 is formed. After concrete is injected into the first notch 303, the second fixing column 306 can form an integral structure with the concrete, thereby allowing the prefabricated track plate 3 and the poured concrete to form an integral structure, thereby further improving the stability of the prefabricated track plate 3.

[0030] For details, see Figure 4 Two drainage channels 103 are provided on the base 1 along the length direction, which are used to timely remove and reduce the water accumulation in the track structure, and multiple pairs of support seats 2 are located between the two drainage channels 103. Specifically, a second notch 304 is symmetrically provided at both ends of the prefabricated track plate 3, and the second notch 304 is located between a pair of first notches 303. When multiple prefabricated track plates 3 are fixed on the support seats 2, the second notches 304 on the adjacent prefabricated track plates 3 are surrounded to form a receiving groove 305. Because the receiving groove 305 is in the middle position, templates for pouring concrete are set on both sides of the prefabricated track plate 3, and then concrete is poured into the receiving groove 305 to pour concrete between the base 1 and the prefabricated track plate 3.

[0031] Preferably, see Figure 4 , Figure 6 A plurality of third fixing columns 102 are arranged in an array along the length direction on the top of the base 1. The plurality of third fixing columns 102 are respectively located in a plurality of receiving grooves 305. When concrete is poured from the receiving grooves 305, the third fixing columns 102 can form an integral structure to limit the movement of the prefabricated track plate 3 in the length direction of the base 1 and improve its stability during use.

[0032] For details, see Figure 5 Each group of first guide columns 101 has four in number and is arranged in a rectangular array. The support seat 2 includes a hollow rectangular block 202. Four vertical through holes 201 are opened in a rectangular array on the top of the rectangular block 202. A pair of connecting blocks 203 are vertically arranged at both ends of the rectangular block 202. A first fixing column 206 is arranged on each connecting block 203. Through this arrangement, the support seat 2 has a hollow structure, which can reduce the amount of materials used and save manufacturing costs.

[0033] Preferably, see Figure 3 , Figure 5 , Figure 7, both ends of the bottom of the prefabricated track plate 3 have symmetrical first inclined surfaces 302, and a support block 204 is provided between each pair of connecting blocks 203. The top of the support block 204 has a second inclined surface 2041 that matches the first inclined surface 302, which is used to cooperate with the first inclined surface 302 to support the prefabricated track plate 3. The support block 204 has a threaded hole 2042 at one end facing the rectangular block 202, and both ends of the rectangular block 202 have connecting holes, and the connecting holes are rotatably connected with adjusting screws 205, which are threadedly connected in the threaded holes 2042. Specifically, the two sides of the support block 204 are respectively in contact with a pair of connecting blocks 203. When it is measured that the substrate 1 has an uneven part, the distance between the support block 204 and the rectangular block 202 can be adjusted by screwing the adjusting screws 205, thereby adjusting the height of the prefabricated track plate 3 supported by the support block 204, so that the heights of the multiple prefabricated track plates 3 after installation are consistent. Specifically, in one embodiment, refer to Figure 8 The adjusting screw 205 includes a screw body 2051 and a retaining ring 2052. The retaining ring 2052 is arranged outside the screw body 2051. When the screw rod of the screw body 2051 is completely inserted into the connecting hole, the retaining ring 2052 abuts against the side of the rectangular block 202 facing the supporting block 204. The retaining ring 2052 can be installed on the screw rod after the screw rod of the screw body 2051 is completely inserted into the connecting hole. Specifically, it can be connected by clamping or welding to limit the movement of the screw body 2051 in the length direction of the base 1.
