A railway ballast laying device and method

Abstract

A railway ballast laying device and method, belonging to the field of railway ballast laying, addresses the problem of placing large stones into the groove first, then laying smaller stones on top of the large stones. To allow the smaller stones to enter the gaps between the large stones, a vibratory machine cannot be used to vibrate them, as this would cause the large stones to crack at high frequencies. Manual pushing using push rods is too cumbersome and affects work efficiency. This invention incorporates a pushing mechanism and a sliding mechanism. The pushing mechanism can adapt to settlement areas of different sizes, while the sliding mechanism can push coarse material to fill the gaps. Compared to existing technologies, this method can automatically push coarse material to fill settlement areas of different widths and depths without manual pushing, thus saving manpower.

Description

Technical Field

[0002] The ballast laying device refers to the equipment used to lay ballast on railway tracks. Ballast is mainly used to support the tracks, drain water, and stabilize the roadbed.

[0003] Patent CN112252096A discloses a ballast laying device for railway construction, including a working box. A first rotating shaft is rotatably mounted on the front and rear ends of the working box. A transport cavity is provided inside the working box. In existing ballast laying devices, due to vibration and pressure during compaction, some ballast may settle. Therefore, ballast filling is required during compaction. To provide rigid support and better filling performance and compactness, railway ballast laying typically uses stones of varying sizes simultaneously. To better mix and arrange the stones, larger stones are usually placed into the groove first, and then smaller stones are laid on top of the larger stones. To allow the smaller stones to enter the gaps between the larger stones, a vibratory machine cannot be used to vibrate them, as this would cause the larger stones to crack at high frequencies. Instead, a pusher is used to push them, which is too cumbersome and affects work efficiency.

The connection between the baffle 805 and the main body 1 of the slag compactor is a fixed connection. The connection between the first baffle 801 and the third baffle 805 is a sliding connection, and the connection between the first baffle 801 and the second baffle 802 is a hinge connection, allowing the first baffle 801 to slide on the surface of the third baffle 805 without causing the second baffle 802 to slide laterally. The second baffle 802 has a second groove 806 inside, and a first spring 807 is fixedly connected to the inner side of the second groove 806. A fourth baffle 808 is provided at the left end of a spring 807.

A slider 9103 is threadedly connected to the outer side of the threaded rod 9102. A second hole 9104 is provided on the inner side of the upper part of the slider 9103. A fourth groove 9105 is connected to the left side wall of the first groove 6. A guide groove 9106 is connected to the inner wall of the fourth groove 9105. The guide groove 9106 has a wavy appearance when viewed from above. The guide groove 9106 and the guide rod 9107 are fitted with a clearance fit. The guide rod 9107 and the first push rod 9108 are fixedly connected, so that the first push rod 9108 can drive the guide rod 9108 when it moves. Rod 9107 moves inside guide groove 9106 and swings along the trajectory of guide groove 9106. Guide rod 9107 is provided inside guide groove 9106. First push rod 9108 is provided inside fourth groove 9105. First push rod 9108 is nested inside second hole 9104. The external structure of first push rod 9108 is cuboid, and the upper and lower sides of first push rod 9108 fit with the inner side of fourth groove 9105. The front and back width of fourth groove 9105 is greater than the front and back width of first push rod 9108, so that first push rod 9108 will not rotate or wobble when moving back and forth inside fourth groove 9105, but will only make smooth back and forth movement.

[0034] The elastic mechanism 92 includes a connecting rod 9201 fixedly connected to the right end below the first push rod 9108.

The outer rear surface of the eighth baffle 9208 is in contact with the inner surface of the fourth hole 9206, and the two front sides of the eighth baffle 9208 are inclined surfaces. The lower end surface of the fourth hole 9206 is connected to the lower end surface of the sixth baffle 812, and the lower end surface of the eighth baffle 9208 and the lower end surface of the sixth baffle 812 are on the same plane. This allows the connecting rod 9201 to move to the left, driving the eighth baffle 9208 to move along the inclined side of the eighth baffle 9208 towards the inside of the fourth hole 9206. After moving past the range of the eighth baffle 9208, the eighth baffle 9208 immediately returns to its original position, blocking the sixth baffle 812.

[0035] A method for laying railway ballast involves opening the main body 1 of a ballast compactor at one end. When encountering a settlement area, the first cylinder 804 and the second cylinder 814 are activated to control the discharge range of the discharge port 7. The coarse material bin 3 is opened first to discharge material, followed by the fine material bin 4. Then, the motor 9101 is activated to drive the second push rod 9204 to push the coarse material back and forth, allowing the fine material to enter the gaps between the coarse material. Finally, the hydraulic cylinder 10 is used to press and the pressure roller 2 is used to compact the material, thus achieving the laying of ballast.

[0036] When the main body 1 of the slag compactor is compacting, if the slag in the branch channel settles, the discharge port 7 will stop at the settling point. The second cylinder 814 and the first cylinder 804 will move to make the discharge port 7 conform to the size of the settling point, preventing excessive material from moving out of the settling point. The specific working method is as follows:

[0037] The first cylinder 804 is activated, pushing the first air rod 803 to move the first baffle 801 forward or backward. Because the first baffle 801 and the second baffle 802 are connected by a hinge, and the second baffle 802 is also connected to the main body 1 of the aggregate compactor by a hinge, the distance between the two first baffles 801 changes, and the inclination angle of the second baffle 802 changes. This allows the front and rear width of the discharge port 7 to adapt to the settling area. The second cylinder 814 is activated, pushing the second air rod 813 forward. The movement causes the sixth baffle 812 to move laterally left and right. Since the connection between the sixth baffle 812 and the fifth baffle 810 is a sliding connection, the lateral movement of the sixth baffle 812 will drive the fifth baffle 810 to move laterally left and right. Under the action of the first spring 807, the left side of the fourth baffle 808 is always in contact with the right side of the fifth baffle 810, so that the left and right width of the discharge port 7 can adapt to the settling area and prevent too much material from moving out of the settling area.

[0038] After the material has settled, open the coarse material hopper 3 to discharge the material, which enters the settling area through the guide plate 5. Then open the fine material hopper 4 to discharge the material, spreading the fine material on top of the coarse material. At this point, the fine material needs to be filled into the gaps between the coarse material. The specific working method is as follows:

[0039] The starter motor 9101 drives the threaded rod 9102 to rotate. Because the slider 9103 is slidably connected to the main body 1 of the slag compactor, the slider 9103 slides. Since the first push rod 9108 is nested inside the second hole 9104, it slides back and forth. Because the first push rod 9108 is fixedly connected to the guide rod 9107, and the guide rod 9107 is nested inside the guide groove 9106, the guide rod 9107 swings left and right as it moves back and forth inside the guide groove 9106. The first push rod 9108 swings left and right, which in turn swings the connecting rod 9201 and the second push rod 9204. Because the second push rod 9204 has a cuboid shape, it will directly push the stone to rotate when it encounters uneven stones, allowing the fine material on the upper layer to enter the gaps between the coarse material. Since the depth of each settlement point is different, and the second push rod 9204 is nested inside the third hole 9205, the second push rod 9204 can directly reach the lowest surface of the settlement point under the action of gravity, and can automatically adapt to settlement points of different depths.

[0040] Because the swing distance of the guide groove 9106 is fixed, when adjusting the width of the discharge port 7, the second push rod 9204 and the connecting rod 9201 will inevitably move out of the range of the sixth baffle 812. When the connecting rod 9201 moves to the edge of the eighth baffle 9208, it can push the eighth baffle 9208 to the rear along the edge of the eighth baffle 9208, so that the second spring 9207 stores force. When the connecting rod 9201 moves to the range of the eighth baffle 9208, the eighth baffle 9208 can immediately reset, blocking the subsequent discharge and preventing too much material from moving out of the settling area.

[0041] In conclusion, the method eliminates the need for manual labor to move large stones to fill the gaps, thus saving manpower.

Then use the hydraulic cylinder (10) to press and the pressure roller (2) to compact the material to achieve the spreading.
