Description

Technical Field

[0001] The utility model belongs to the technical field of railway engineering and maintenance, and in particular relates to a railway ballast shaping system. Background Art

[0002] At present, the railway engineering section adopts the "excavator + manual" method to carry out construction work. The construction method is as follows:

[0003] 1) Before the large machine tamping, the excavator uses the bucket to dig up the ballast at the bottom of the line slope along the length of the line, and then unloads the ballast in the bucket to the tamping area on both sides of the rail;

[0004] 2) Manually level the ballast on both sides of the rails to make the ballast continuous and accumulated on both sides of the rails;

[0005] 3) After the large machine tamping, the excavator uses the bucket or scraper to shape the slope;

[0006] 4) Manually clean the floating ballast on the pillow surface and remove the ballast mixed in the fastener area.

[0007] The construction method currently adopted by the engineering section has the following shortcomings:

[0008] 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;

[0009] 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 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;

[0010] 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;

[0011] 4) According to the existing large-scale machine group tamping operation, multiple excavators and a large number of manpower are needed to meet the needs, which increases the risk of on-site construction management and control.

[0012] 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.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0037] like Figure 1 As shown, this embodiment provides a railway ballast shaping system, including two fast-moving excavators A and B, a tilting bucket attachment 3, a track plow attachment 5 and a cleaning attachment 4, which is mainly suitable for standard 60kg / m rails, 1435mm gauge, type II sleepers or type III sleepers in the railway system.

[0038] like Figure 2 As shown, the working method is as follows:

[0039] 1. Before tamping, excavator A cooperates with the tilting bucket attachment to move along the line direction, and controls the tilting bucket to gather the ballast at the bottom of the slope to the shoulder;

[0040] 2. At this time, excavator B cooperates with the track center plow attachment to move along the line direction, and uses the track center plow to distribute the shoulder ballast to the track center area close to the rail;

[0041] 3. After tamping, excavator A cooperates with the tilting bucket attachment to move along the route to shape the slope to make it more uniform;

[0042] 4. At this time, excavator B cooperates with cleaning accessories to move along the line direction to clean the ballast on the pillow surface and pillow shoulders, and sweeps the ballast on the pillow surface and pillow shoulders into the gaps between the sleepers.

[0043] In this embodiment, the tilting bucket attachment is a standard excavator bucket, which is mainly used to dig up the ballast at the bottom of the line slope in sequence along the length direction of the line, and then unload the ballast in the bucket to the tamping area on both sides of the rail. Figure 1 shown.

[0044] In this embodiment, if Figure 3 As shown, the track core plow attachment 5 includes a supporting frame 51, a side plow scraping mechanism 52, a first hydraulic rotary drive 53, a quick connector 54, and a walking wheel set 55.

[0045] The support frame 51 in the device is welded from profiles, on which are installed a side plow ballast scraping mechanism 52, a first hydraulic rotary drive 53, a quick connector 54, and a walking wheel set 55, which play the role of overall support; the quick connector 54 is used to connect the device to the excavator arm, and the excavator drives the device to move on the railway rail line; the first hydraulic rotary drive 53 controls the overall rotation and swing of the device, as well as the reversing operation; the walking wheel set 55 controls the device to move along the railway rails so as not to go off the track; the side plow ballast scraping mechanism 52 is used to pull off the ballast on the sleepers and on the side of the roadbed so that it is evenly distributed near the rails. The specific usage scenarios are as follows: Figure 4 shown.

[0046] like Figure 5 , 6 As shown, the side plow scraping mechanism 52 includes a scraping plate a, a second hydraulic rotary drive b, a guide groove block c, a spiral locking buckle d, and a side plowboard e. The spiral locking buckle d is composed of an upper U-shaped groove d1, a pull 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. Figure 7 As shown, the upper U-shaped groove d1 is connected to the side plowboard e through a connecting pin, the lower U-shaped groove d3 is connected to the scraper board a through a connecting pin, the spiral sleeve d6 is welded into a whole by two left-handed nuts and a bracket, the upper U-shaped groove d1 and the right-handed screw d5 are welded into a whole and pass through the spiral sleeve, the lower U-shaped groove d3 and the left-handed screw 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 connected to it will rotate at the same time. The screw rod d7 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 at the same time, the left-handed screw rod d7 connected to it 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.

[0047] The traveling wheel set 55 includes rollers, bearings, and a rotating shaft. The traveling wheel set 55 controls the device to move along the railway rails without crossing the rails.

[0048] In the above embodiment, the side plow scraper mechanism 52 is fixed on the left and right sides of the supporting frame 1 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.

[0049] When in use, the excavator is connected to the track center plow attachment through a quick connector 54. Driven by the excavator, the device moves quickly on the rail line, adjusts the angle between the side plow scraping mechanism and the rail, adjusts the scraping range, drives the scraping plate to pull the gravel ballast on both sides of the line track, and ensures the consistency and uniformity of the gravel ballast on the line track bed.

[0050] In this embodiment, the cleaning attachment is mainly composed of a frame 41, a hydraulic rotary drive 42, a quick connector 43, a lifting mechanism 44, a hydraulic rotary drive assembly 45, a running assembly 46, a roller brush assembly 47, and a protective cover assembly 48. Figure 8 , Fig. 9 shown.

[0051] The frame 41 of the cleaning attachment is welded by profiles and plays the role of overall support. A hydraulic rotary drive 42, a quick connector 43, a lifting mechanism 44, a hydraulic rotary drive assembly 45, a running assembly 46, and a roller brush assembly 47 are installed on it; the hydraulic rotary drive 42 controls the overall rotation and swing of the ballast cleaning device so that the running wheels in the running assembly are just placed on the rails, and the angle can be adjusted at will, which is convenient for adjusting the angle of the ballast cleaning device during hoisting and transportation; the quick connector 43 is used to connect the device to the excavator arm, The device is driven by an excavator to perform mobile operations on the railway rail line; the lifting mechanism 44 drives the lifting and lowering of the screw nut through the hydraulic motor, so that the roller brush assembly 47 is raised and lowered relative to the rail as a whole, and the distance between the roller brush and the sleeper is controlled; the running assembly 46 controls the movement of the ballast cleaning accessories along the railway rail to prevent it from going off the track; the hydraulic rotary drive assembly 45 is used to drive the roller brush assembly 47 to perform circular motion, and through the rolling of the roller brush assembly 47, the ballast gravel on the upper surface of the sleeper is rolled to the gap between the sleepers, ensuring that there is no ballast gravel on the upper surface of the sleeper.

[0052] like Fig.10 As shown, the lifting mechanism 44 includes a hydraulic motor 441, an external fixed guide seat 442, a trapezoidal screw nut seat 443, a trapezoidal screw 444, an inner lifting tube 445, and a running leg 446. The hydraulic motor 441 is connected to the trapezoidal screw 444, the lower end of the running leg 446 is connected to the running roller by a bolt, the upper end of the running leg 446 is connected to the inner lifting tube 445 by a screw, and the trapezoidal nut seat 443 is connected to the inner lifting tube 445 by a bolt. When the hydraulic motor 441 drives the trapezoidal screw 444 to rotate, the nut seat will drive the inner lifting tube 445 to move up and down, thereby driving the running leg to move up and down, controlling the relative position height between the running wheel and the roller brush, and ensuring that the roller brush cleans the gravel on the sleeper during cleaning.

[0053] like Fig.11As shown, the roller brush assembly 47 includes a passive sprocket 471, a supporting bearing seat 472, a hose 473, a roller brush shaft 474, and a pin 475. The hydraulic rotary drive assembly 45 includes a driving sprocket 451, a chain 452, and a hydraulic motor 453. The roller brush assembly 47 and the hydraulic motor 453 are respectively installed at the bottom and top of the skeleton 41. When the hydraulic motors 453 installed on the left and right sides of the skeleton 41 rotate at the same time, the hydraulic motor 453 drives the driving sprocket 451 to rotate, and drives the passive sprocket 471 to rotate through the transmission of the chain 452, thereby driving the rotation of the roller brush shaft 474. The roller brush shaft 474 is connected with hoses 473 of different lengths through pins. When the hose 473 contacts the gravel on the upper surface of the sleeper, the gravel is swept to the gap between the sleepers by rotation. At the same time, the roller brush device is driven by the excavator to move along the railway line, thereby realizing the function of quickly cleaning the gravel on the sleepers along the railway.
