Description

Technical Field

[0001] The utility model relates to the technical field of ballastless track construction, in particular to a cutting device for geotextile used for ballastless track. Background Art

[0002] At present, the technical application of ballastless track has gradually replaced the existing ballasted track construction in high-speed railways. As the bearing basis for high-speed railway trains, the construction quality of ballastless track is particularly critical.

[0003] According to the construction form of ballastless track, it consists of two parts: a base plate and a roadbed plate. A layer of geotextile is laid between the two parts to act as an isolation layer. In order to effectively control the displacement and misalignment of the two parts, two limit grooves are set on each independent base plate, and an isolation layer (geotextile) is also laid at the bottom of the groove.

[0004] Considering the convenience of dismantling the limiting template and design requirements, the structure of the limiting groove is a three-dimensional T-shaped mode that is narrow at the bottom and wide at the top. This causes the size of the geotextile cut from the upper mouth to be larger than the size required at the bottom of the groove, and secondary cutting is required to meet the needs of use. This not only reduces construction efficiency and increases labor costs, but also poses quality risks due to uneven cutting. Utility Model Content

[0028] The present invention will now be discussed with reference to exemplary embodiments. It should be understood that the embodiments discussed are only intended to enable those skilled in the art to better understand and implement the present invention, rather than to imply any limitation on the scope of the present invention.

[0029] As used herein, the term “including” and variations thereof are to be interpreted as open-ended terms meaning “including, but not limited to.” The term “based on” is to be interpreted as “based, at least in part, on.” The terms “one embodiment” and “an embodiment” are to be interpreted as “at least one embodiment.”

[0030] Figure 1 A diagram schematically showing the structural arrangement of the base plate of the ballastless track; Figure 2 A diagram schematically showing a construction state of a cutting device for geotextile for ballastless track on a base plate according to an embodiment of the utility model; Figure 3 A schematic diagram showing the structural arrangement of a cutting device for geotextile for ballastless track according to an embodiment of the utility model; Figure 4 A schematic top view of a cutting tool according to an embodiment of the present invention is shown; Figure 5 The top view of a rectangular limiting ring according to an embodiment of the utility model is schematically shown. Figure 1-Figure 5 As shown, in this embodiment, the cutting device of the geotextile for ballastless track includes:

[0031] A cutting tool 1 is arranged in a limiting groove 2 of a base plate 11 of a ballastless track, and cuts the geotextile at the bottom and top of the limiting groove 2;

[0032] A rectangular limiting ring 3 is supported above the limiting groove 2, and its inner wall is aligned with the inner wall of the upper end of the limiting groove 2;

[0033] A rectangular pressure plate 4 is arranged in the rectangular limiting ring 3, and its outer wall is slidably connected with the inner wall of the rectangular limiting ring 3, and can reciprocate along the vertical direction;

[0034] The driving component 5 drives the rectangular pressing plate 4 to move back and forth in the vertical direction, transmits force to the cutting tool 1 through the rectangular pressing plate 4, and cuts the geotextile located at the bottom and top of the limiting groove through the cutting tool. In this way, the driving component 5 can drive the rectangular pressing plate 4 to move up and down in the rectangular limiting ring 3. When moving to the bottom, the rectangular pressing plate 4 and the cutting tool 1 located in the limiting groove 2 abut each other, thereby applying pressure to the cutting tool 1. Through the squeezing between the rectangular pressing plate 4 and the top of the cutting tool 1 and the squeezing of the bottom of the cutting tool 1 to the bottom of the limiting groove 2, the cutting tool 1 can simultaneously cut the geotextile located above it (i.e., between the top of the rectangular pressing plate 4 and the cutting tool 1) and the geotextile located below it (i.e., at the bottom of the limiting groove 2), thereby effectively improving construction efficiency, reducing labor costs, and effectively avoiding the quality risks caused by uneven cutting.

[0035] Furthermore, if Figure 3 and Figure 5 As shown, in this embodiment, a pedal 6 abutting against the base plate is provided on the bottom outer wall of the rectangular limiting ring 3. With such a configuration, during the construction and cutting of the geotextile, the position of the rectangular limiting ring 3 can be stabilized and secure by stepping on the pedal 6, thereby ensuring that the movement trajectory of the rectangular pressing plate 4 is stable and reliable, which can effectively ensure that the geotextile is accurately cut through the mutual extrusion between the rectangular pressing plate 4 and the cutting tool 1, thereby ensuring the quality of the geotextile.

[0036] Furthermore, if Figure 3 and Figure 4 As shown, in this embodiment, the cutting tool 1 is an annular knife, and its top and bottom ends have annular blades;

[0037] The vertical cross section of the cutting tool 1 is an isosceles trapezoid, and the upper base of the isosceles trapezoid is located above the lower base. This arrangement allows the cutting tool 1 to be adapted to the shape of the limiting groove 2 of the base plate, ensuring that the cutting tool 1 can be accurately embedded in the limiting groove 2 of the base plate, and the geotextile located on its upper and lower sides is squeezed and cut through its upper and lower annular blades, so that the size of the cut geotextile is high and the cutting quality is guaranteed; and the above arrangement can achieve the simultaneous cutting of the upper and lower geotextiles of different sizes required for the limiting groove 2 of the base plate of the ballastless track, effectively solving the problem of the need for secondary cutting of the geotextile in the traditional solution, and effectively improving the construction efficiency.

[0038] Furthermore, if Figure 3 As shown, in this embodiment, the driving assembly 5 includes: a first connecting rod 7, a second connecting rod 8, a driving rod 9 and a supporting rod 10;

[0039] The first connecting rod 7 is arranged along the vertical direction, one end of which is connected to the rectangular pressing plate 4, and the other end is connected to the second connecting rod 8;

[0040] The second connecting rod 8 is an arc-shaped rod, one end of which is connected to the top end of the first connecting rod 7, and the other end is connected to the driving rod 9;

[0041] The driving rod 9 is arranged in the horizontal direction, one end of which is connected to the arc rod and the other end is a free end;

[0042] The support rod 10 is arranged along the vertical direction, one end of which is connected to the top of one side of the rectangular limiting ring 3, and the other end is hinged on the outer wall of the end of the driving rod 9 close to the arc rod. In this way, by driving the free end of the driving rod 9 to move up and down, the other end of the driving rod 9 can drive the arc rod and the first connecting rod 7 to move, so that the first connecting rod 7 moves up and down, thereby driving the rectangular pressing plate 4 to move up and down, so as to achieve cutting of the geotextile or leaving the cutting state, making the operation convenient and quick, and effectively improving the construction efficiency.

[0043] According to the above solution of the utility model, the utility model can effectively solve the problem that the traditional solution requires secondary cutting of the geotextile, resulting in low cutting efficiency and inability to ensure cutting quality.

[0044] According to the above scheme of the utility model, the cutting size error of the isolation layer (geotextile) at the limiting groove can be effectively guaranteed, thereby ensuring the construction quality.

[0045] According to the above scheme of the utility model, the cutting efficiency of the isolation layer (geotextile) at the limiting groove can be effectively improved and the construction cost can be reduced.

[0046] According to the above scheme of the utility model, the cutting consumption of the isolation layer (geotextile) at the limiting groove can be effectively reduced, thereby reducing the material cost.

[0047] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
