Description

Technical Field

[0001] The utility model relates to the technical field of railway track ballast shaping, in particular to a railway track ballast shaping device. Background Art

[0002] In view of the pain points of ordinary railway lines, such as insufficient ballast before tamping, inconvenient restoration of the roadbed shape after tamping, and difficulty in cleaning the floating ballast on the pillow surface, the construction method currently adopted by the engineering section has the following shortcomings:

[0003] (1) Using an excavator to dig the ballast at the bottom of the slope will not only create an excavation section but also affect the appearance of the roadbed;

[0004] (2) When using an excavator to unload ballast, the ballast is not uniform and continuous along the line direction, and there is ballast accumulation and spacing. Even if the bucket is used to flatten it, ballast will still accumulate on the top of the rail and in the fastener area. The workload of manual cleaning and ballast leveling is large and the efficiency is low. If the cleaning is not in place, there is a risk of affecting driving safety;

[0005] (3) After the large machine tamping, the ballast splashed on the pillow surface and pillow shoulder has to be cleaned manually, which is labor-intensive and inefficient;

[0006] (4) According to the existing large-scale machine group tamping operation, the operating efficiency of a skylight point is about 5-7 kilometers. To match this efficiency, multiple excavators and a large number of manpower are required to meet it, which increases the risk of on-site construction management and control.

[0007] Based on the above analysis, mechanized assembly line operation, greatly improving the efficiency of ballast shaping operations, and significantly reducing the number of excavators and labor are the best solutions to solve the current pain points of ballast shaping construction before and after large-scale machine tamping in the maintenance section. Summary of the invention

[0009] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a railway ballast shaping device, including a supporting frame, a side plow ballast scraping mechanism, a first hydraulic rotary drive, a quick connector, and a walking wheel set.

The side plow ballast scraping mechanism includes a ballast scraping plate a, a second hydraulic rotary drive b, a guide groove block c, a spiral locking buckle d, and a side plow plate e. The spiral locking buckle d is composed of an upper U-shaped groove d1, a pulling rod d2, a lower U-shaped groove d3, a connecting pin d4, a right-handed screw d5, a spiral sleeve d6, and a left-handed screw d7. The upper U-shaped groove d1 is connected to the side plow plate e through a connecting pin, and the lower U-shaped groove d3 is connected to the ballast scraping plate a through a connecting pin. The spiral sleeve d6 is welded into a whole by two left-handed nuts and a bracket, and the upper U-shaped groove d1 and the right-handed screw d5 are welded into a As a whole, the spiral sleeve passes through the lower U-shaped groove d3 and the left-handed screw rod d7 are welded into a whole and pass through the spiral sleeve. The guide groove block c is arranged on the side plowboard e, and the scraper board a is provided with a matching slide groove. When the pull rod d2 is rotated clockwise, the pull rod d2 will drive the spiral sleeve d6 to rotate, and the left-handed screw rod d7 connected thereto will move upward, driving the lower U-shaped groove d3 to move upward accordingly. The lower U-shaped groove d3 drives the scraper board a to pass through the guidance of the guide groove block c and move upward as a whole, thereby reducing the relative height between the side plowboard e and the scraper board a; when the pull rod d2 is rotated counterclockwise, the pull rod d2 will drive the spiral sleeve d6 to rotate, and the left-handed screw rod d7 connected thereto will move downward, driving the lower U-shaped groove d3 to move downward accordingly. The U-shaped groove d3 drives the scraper board a to pass through the guidance of the guide groove block c and move downward as a whole, thereby increasing the relative height between the side plowboard e and the scraper board a.

[0010] In the above technical solution, the side plow scraper mechanism is fixed on the left and right sides of the supporting frame through a supporting seat and a supporting shaft, and the side plowboard e is driven to rotate through the second hydraulic rotary drive b to adjust the angle between the side plowboard and the track, thereby adjusting the amount range of separated ballast, and the height of the scraper board a is adjusted through the spiral locking buckle d to adapt to the height of different roadbed gravel.

[0011] In the above technical solution, the running wheel group includes rollers, bearings, and a rotating shaft, and the running wheel 5 control device moves along the railway rails without going off the track.

[0012] In the above technical solution, the support frame is welded from profiles, on which the side plow ballast scraping mechanism, hydraulic rotary drive, quick connector, and walking wheel set are installed, and the support frame plays the role of overall support.

[0013] The utility model provides a railway ballast shaping device, which is driven by an excavator to move along the railway, and distributes the ballast on both sides of the sleepers to the area of ​​the track center close to the rails, so that the ballast crushed stones are more evenly distributed; the ballast distribution opening and closing angles are adjusted by a hydraulic motor, so that the opening and closing angles can be increased or decreased according to actual needs; and manual shaping of the crushed stones on the track bed slope is replaced, thereby improving the working efficiency.
