Description

Technical Field

[0001] The utility model relates to the technical field of slope measurement, in particular to a slope measurement device for ballastless track construction. Background Technique

[0002] The high-speed railway track slab is a new type of sub-rail component that distributes the load transmitted by the train through the rail to the base under the slab, and is one of the devices to ensure the fast and safe operation of high-speed rail vehicles. During the construction of cast-in-place concrete for the track slab, the slope control of the concrete surface is generally carried out manually with a concrete trowel. However, manual operation relies on the eyes of the operator for observation, which is prone to large slope errors and fails to meet the design requirements.

[0003] For example, the Chinese patent with the publication number CN 204644815 U discloses a slope detection device for a double-block ballastless track bed slab, including a movable steel frame and multiple groups of detection devices arranged at the lower end of the movable steel frame. The characteristics are as follows: the detection device includes a slope ruler and connecting rods respectively connected to the slope ruler and the movable steel frame. The connecting rod is connected to the movable steel frame through a height adjustment mechanism. The height adjustment mechanism includes a threaded rod and a nut. The lower end of the threaded rod is connected to the top end of the connecting rod, the top end of the threaded rod passes through the movable steel frame, and the nut is located on the threaded rod on both sides of the movable steel frame. The detection device also includes a scale, and the scale is installed at the top end of the nut, and there are scales on the scale. The utility model has a simple structure, convenient operation, fast measurement and positioning speed, high positioning accuracy, is applicable to the slope measurement of ballastless track bed slabs of various specifications and sizes, and the quality effect of plastering meets the design and construction requirements, ensuring the construction quality of double-block ballastless tracks.

[0004] Although the above device has high positioning accuracy and fast measurement speed during slope measurement, in the subsequent concrete plastering, if the concrete at the top of the ballastless track bed slab is too high, the user needs to continuously move the whole device back and forth for leveling, which is relatively laborious to use. Therefore, we propose a slope measurement device for ballastless track construction to solve the above problems. Content of the Utility Model

[0023] Embodiment: As Figures 1-4 shown, the present invention provides a slope measuring device for ballastless track construction, including an assembly table 11. Smoothing components 33 are arranged on both sides of the bottom of the assembly table 11. Control components 22 for changing the working state of the smoothing components 33 are arranged on both sides of the assembly table 11. Handle 101101 is fixedly connected to both sides of the top of the assembly table 11. A level 102102 is installed in the middle of the assembly table 11. Fixed rods 103103 are fixedly connected to both sides of the bottom of the assembly table 11. The two fixed rods 103103 are symmetrically distributed along the axis of the assembly table 11. A sliding table 104104 is fixedly connected to the end of the fixed rod 103103 away from the assembly table 11. A track 105105 is arranged at the bottom of the sliding table 104104. The sliding table 104104 is placed on the top of the track 105105 and is slidably connected thereto. Roadbed slabs are arranged on both sides of the track 105. The top of the roadbed slab is in contact with the smoothing component 33. The cooperation of multiple components improves the use comfort of the device and eliminates the need for repeated smoothing of the ballastless slab 106106.

[0024] Among them, two threaded rollers 201201 are provided in the control component 22. The two threaded rollers 201201 are placed on both sides of the assembly table 11. One end of the threaded roller 201201 penetrates through the assembly table 11 and extends to the bottom of the table. The two threaded rollers 201201 are symmetrically distributed along the axis of the assembly table 11. The threaded roller 201201 is threadedly connected to the assembly table 11. A screwing wheel 202202 is fixedly connected to the top of the threaded roller 201201. A positioning plate 203203 is arranged on the side of the two threaded rollers 201201 close to the center of the assembly table 11. A plurality of uniformly distributed scale grooves 204204 are formed on the surface of the positioning plate 203203. An assembly cylinder 205205 is sleeved on the bottom of the threaded roller 201201. A rotating bearing 206206 is arranged inside the assembly cylinder 205205. The outer ring wall of the rotating bearing 206206 is fixedly connected to the assembly cylinder 205205, and the inner ring wall of the rotating bearing 206206 is fixedly connected to the threaded roller 201201. A connecting roller 207207 is fixedly connected to the end of the assembly cylinder 205205 away from the threaded roller 201201. The bottom of the connecting roller 207207 is in contact with the leveling component 33. During the period when the concrete of the roadbed slab 106106 is poured and enters the surface leveling process, the threaded rollers 201201 on both sides of the assembly table 11 are adjusted, and the height is calculated according to the set positioning plate 203203 and scale grooves 204204. At the same time, the threaded rollers 201201 are adjusted in cooperation with the level 102102, so that the gradient ruler 301301 at the bottom of the threaded roller 201201 can be adapted to different angles.

[0025] Furthermore, two gradient gauges 301301 are provided in the leveling component 33. The tops of the two gradient gauges 301301 are fixedly connected to the bottoms of the two connecting rollers 207207 respectively. Inclined surfaces 302302 are formed on both sides of the gradient gauge 301301, and the two inclined surfaces 302302 on both sides are symmetrically distributed along the axis of the gradient gauge 301301. A horizontal platform 303303 is formed in the middle of the gradient gauge 301301. Two groups of toggle plates 304304 are installed on the top of the horizontal platform 303303. A communication window 305305 is formed on the side of the gradient gauge 301301 away from the center of the assembly table 11. The bottom of the gradient gauge 301301 contacts the roadbed slab 106106. The assembly table 11 is placed on the top, and the two sliding platforms 104104 at its bottom are placed on the top surface of the track 105105. The gradient gauges 301301 on both sides press on the roadbed slab 106106. The user moves the whole device by grasping the handle 101101. When moving the whole device along the direction of the track 105105, the inclined surfaces 302302 formed on both sides of the gradient gauge 301301 are convenient for shoveling up the concrete on the roadbed slab 106106 whose top surface is higher than the gradient gauge 301301. The shoveled concrete is discharged from the communication window 305305 driven by the multiple toggle plates 304304 on the top of the horizontal platform 303303. The discharged concrete can be used in subsequent low-lying areas, and thus the top surface of the roadbed slab 106106 can be leveled.

[0026] Working principle: When using this device, during the period from the completion of the concrete pouring of the roadbed slab 106106 to the surface leveling, the threaded rollers 201201 on both sides of the assembly table 11 are adjusted, and the height is calculated according to the set positioning plates 203203 and scale grooves 204204. At the same time, the threaded rollers 201201 are adjusted in cooperation with the spirit level 102102, so that the gradient gauges 301301 at the bottoms of the threaded rollers 201201 can be adapted to different angles; then the assembly table 11 is placed on the top, and the two sliding platforms 104104 at its bottom are placed on the top surface of the track 105105. The gradient gauges 301301 on both sides press on the roadbed slab 106106. The user moves the whole device by grasping the handle 101101. When moving the whole device along the direction of the track 105105, the inclined surfaces 302302 formed on both sides of the gradient gauge 301301 are convenient for shoveling up the concrete on the roadbed slab 106106 whose top surface is higher than the gradient gauge 301301. The shoveled concrete is discharged from the communication window 305305 driven by the multiple toggle plates 304304 on the top of the horizontal platform 303303. The discharged concrete can be used in subsequent low-lying areas, and thus the top surface of the roadbed slab 106106 can be leveled. Compared with the existing device, it is not necessary to repeatedly level and push and pull, which is more labor-saving. Only by easily moving the device can the large-area leveling work be completed, reducing the labor intensity and improving the safety and comfort of construction.
