Technical Field

The invention belongs to the technical field of high-speed railway ballastless track construction, relates to construction of ballastless track bed plates, and particularly relates to a slope collecting device for a drainage slope during pouring construction of ballastless track bed plates.

Background

Both sides of a high-speed railway ballastless track bed plate are generally provided with drainage slopes with certain slopes. The bed plate adopts concrete placement, and after concrete placement accomplished, the domatic face that needs to carry out the manual work of bed plate top surface and drainage slope was received the face. At present constructor all adopts the straight angle spatula when receiving the face, and the problem that exists need receive the face respectively to bed plate top surface and domatic, and not only the efficiency of construction is low, and the bed plate top surface is difficult to control with the line type of domatic juncture and the slope precision of drainage slope moreover, influences construction quality.

Disclosure of Invention

The invention aims to solve the problems and provides a construction device special for collecting a drainage slope of a ballastless track bed plate, so that the construction efficiency and the construction quality are improved.

The technical scheme of the invention is as follows:

the utility model provides a ballastless track bed plate drainage slope receipts slope device which characterized in that: the slope collecting scraper is characterized by comprising a rectangular slope collecting scraper and a rectangular slope control scraper, wherein the length of the slope collecting scraper is equal to the width of a drainage slope of a ballastless track base plate, and one end of the slope collecting scraper is aligned with one end of the slope control scraper and is rotationally connected with the slope control scraper through a hinge; an inverted U-shaped handle is arranged on the top surface of the slope retracting scraper along the direction perpendicular to the butt joint seam of the slope control scraper, and a through hole is formed in one side, facing the slope control scraper, of the handle; the top surface of the gradient control scraper is provided with two lug plates; an adjusting rod is movably connected between the handle and the lug plates, one end of the adjusting rod is rotatably connected with the two lug plates through a pin shaft, the other end of the adjusting rod penetrates through a through hole in the handle, and a positioning nut is respectively screwed on two sides of the through hole.

The slope collecting scraper and the slope control scraper are arranged and connected into an organic whole through the hinges, and the boundary between the top surface of the base plate and the drainage slope surface can be formed at one time, so that the construction efficiency can be improved, and the slope precision of the drainage slope can be ensured. The included angle can be adjusted in a flexible way between the slope scraper and the slope control scraper, and the slope scraper is suitable for construction of drainage slopes with different slopes.

Detailed Description

As shown in fig. 1 and 2, the slope collecting scraper comprises a rectangular slope collecting scraper 1 and a rectangular slope control scraper 2, wherein the length of the slope collecting scraper 1 is equal to the width of a drainage slope of a ballastless track base plate, one end of the slope collecting scraper 1 is aligned with one end of the slope control scraper 2, a hinge 3 is arranged at the joint of the slope collecting scraper and the slope control scraper, and two sides of the hinge 3 are respectively connected with the top surfaces of the slope collecting scraper 1 and the slope control scraper 2; an inverted U-shaped handle 4 is arranged on the top surface of the slope retracting scraper 1 along the direction perpendicular to the aligned joint of the slope control scraper, and a through hole is formed in one side, facing the slope control scraper, of the handle; the top surface of the gradient control scraper 2 is provided with two lug plates 5; an adjusting rod 6 is movably connected between the handle 4 and the ear plates 5, one end of the adjusting rod 6 is rotatably connected with the two ear plates 5 through a pin shaft, and the other end of the adjusting rod penetrates through a through hole in the handle and is respectively in threaded connection with a positioning nut 7 on two sides of the through hole.

According to the structure, the two positioning nuts 7 on the adjusting rod 6 are loosened, the slope retracting scraper 1 and the slope control scraper 2 can freely rotate around the loose-leaf shaft to form a certain included angle, and the included angle can be fixed by screwing the two positioning nuts.

When the slope retracting scraper is used, the included angle between the slope retracting scraper and the slope control scraper is determined according to the designed included angle between the top surface of the base plate and the slope surface of the drainage slope.

As shown in fig. 3, after the concrete of the base plate is poured, the slope retracting scraper 1 is placed on the drainage slope of the base plate 8, the slope control scraper 2 is placed on the top surface of the base plate 8, the handle 4 is held by hand to move the slope retracting scraper and the slope control scraper longitudinally along the base plate, so that the top surface of the base plate and the drainage slope can be retracted simultaneously, and the slope of the drainage slope can be ensured to meet the design requirements; meanwhile, lines at the junction of the top surface and the slope surface can be formed at the joint of the slope collecting scraper and the slope control scraper, and the line type can be kept straight, so that the appearance quality is ensured.
