Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and particularly to a ballast cleaning device and a long rail vehicle group. Background Art

[0002] A long rail vehicle group is a special vehicle group composed of a variety of special vehicles with different functions and structures for transporting and welding long rails. In the construction of a railway seamless line, the long rail vehicle group is responsible for the tasks of loading, transporting, unloading and recycling old rails of long rails. For example, the long rail vehicle group has the function of unloading the transported rails to both sides of the line. In order to make the unloaded rails be stored stably on both sides of the line and ensure that the rail surface of the unloaded rails is not higher than the rail surface of the line, it is necessary to level the ballast protruding on both sides of the line. That is to say, in order to provide a stable and safe storage space for the rails, a groove with a flat bottom needs to be dug out on the originally protruding ballast.

[0003] At present, in order to level the ballast before the rail unloading operation, most railway administrations adopt manual operation, and a few have installed rigid fixing devices on the vehicles used during the rail unloading operation. In the prior art, the device consists of a column and a scraper. The column is vertically installed on the side of the vehicle by means of bolt fastening and extends towards the ground, and the scraper is installed at its lower end. When it is necessary to level the ballast before the rail unloading operation, the device is installed on the vehicle. After manually adjusting the height of the scraper at the lower end, the locomotive is started to pull the operation vehicle to level the ballast at the place where the vehicle passes. When encountering signal equipment or turnouts beside the road during the operation, stop to disassemble the device, and then reinstall it after passing. After the operation is completed, remove the device and store it separately.

[0004] However, the above-mentioned device needs to be manually installed and disassembled during the operation, which takes a long time and has low operation efficiency. Moreover, when there are large-weight obstacles such as old rails buried in the ballast, it is impossible to identify hidden obstacles in advance. When encountering them during the operation, collisions will occur, damaging the operation device and even endangering the safety of train operation. Summary of the Invention

One end of the two fourth side plates 4013 is fixedly connected to the fourth base plate 4012, and the other ends of the two fourth side plates 4013 are respectively provided with sixth through holes 40131 for hinged connection with one end of the swing arm 402.

[0144] It should be noted that a limiting plate 4014 is further provided on the side of the stopper 4011 away from the swing arm 402. The limiting plate 4014 is fixedly arranged on the fourth side plate 4013, and the limiting plate 4014 can play a role in improving the stability of the stopper 4011.

[0145] As Figure 18 and Figure 19 shown, the swing arm 402 includes a first swing arm 4021, a second swing arm 4022, a connecting shaft 4023 and a second pin shaft 4024. The second pin shaft 4024 is arranged between the first swing arm 4021 and the second swing arm 4022, and the second pin shaft 4024 is used to connect the swing arm support 401 and the connecting frame 301. The connecting shaft 4023 is arranged in the middle of the first swing arm 4021 and the second swing arm 4022 for connecting with the other end of the elastic member 302, and the connecting shaft 4023 abuts against the first movable groove 30111 and the second movable groove 30121.

[0146] It should be noted that when the swing arm 402 is in a vertical state, if the push rod 102 retracts, it will drive the sliding member 202 to move in the sliding groove 2011, thereby driving the connecting frame 301 to move. Since one end of the elastic member 302 is fixed to the swing arm 402 and the other end is fixed to the connecting frame 301, the elastic member 302 will be stretched, thereby generating a certain pulling force on the swing arm 402, driving the actuating assembly 50 mounted on the swing arm 402 to level the ballast.

[0147] It should be noted that when the first swing arm 4021 and the second swing arm 4022 are retracted, the first movable groove 30111 and the second movable groove 30121 respectively contact the connecting shaft 4023, so as to push the first swing arm 4021 and the second swing arm 4022 to rotate. When the first swing arm 4021 and the second swing arm 4022 of the swing arm are extended, the first movable groove 30111 and the second movable groove 30121 are separated from the connecting shaft 4023, but the plates on the upper sides of the first movable groove 30111 and the second movable groove 30121 will rest on the connecting shaft 4023, so as to ensure that the first connecting frame 3011 and the second connecting frame 3012 will not fall off from the connecting shaft 4023.

[0148] In addition, an installation plate 4025 can be further provided at one end of the swing arm 402 away from the swing arm support 401, and the installation plate 4025 is used for installing the actuating assembly 50.

[0149] It should be noted that the mounting plate 4025 can be detachably connected to the swing arm 402. For example, it can be connected by threaded connection, pin connection or snap connection. The specific structure of the detachable connection is not limited in this embodiment. Further, the mounting plate 4025 and the swing arm 402 can also be non-detachably connected. For example, the connecting ends of the mounting plate 4025 and the swing arm 402 are both made of metal, and at this time, they can be connected by welding.

[0150] Specifically, a seventh through hole 4026 is provided on the mounting plate 4025, and the actuating assembly 50 is mounted on the mounting plate 4025 through the seventh through hole 4026.

[0151] In addition, as Figures 20 to 22 shown, the actuating assembly 50 includes a push plate 501, a cover plate 502, a fifth bottom plate 503 and two relatively arranged fifth side plates 504. One ends of the two fifth side plates 504 are fixedly connected to the fifth bottom plate 503, and the other ends of the two fifth side plates 504 are fixedly connected to the push plate 501.

[0152] It should be noted that the push plate 71 can be a pressed part, that is, the push plate 71 is an integrally formed structure pressed by a whole steel plate through a mold. When the push plate 71 is a pressed part, the overall rigidity of the push plate 71 is better.

[0153] As Figures 23 to 25 shown, the push plate 501 includes a first surface 5011, a second surface 5012 and a third surface 5013 connected between the first surface 5011 and the second surface 5012. The third surface 5013 is fixedly connected to the other ends of the two fifth side plates 504 and the third surface 5013 is parallel to the fifth bottom plate 503; there is a first preset angle between the first surface 5011 and the third surface 5013 and the extending direction of the first surface 5011 faces the fifth bottom plate 503; there is a second preset angle between the second surface 5012 and the third surface 5013 and the extending direction of the second surface 5012 is away from the fifth bottom plate 503.

[0154] It should be noted that when there is a certain angle between the first surface 5011 and the third surface 5013 and there is a certain angle between the second surface 5012 and the third surface 5013, the push plate 501 can play a guiding role when leveling the ballast, and divert the excess ballast to the outside of the vehicle.

[0155] Specifically, the first preset angle and the second preset angle can be 60° - 120°. In actual use, the first preset angle and the second preset angle can be selected within the above range according to the requirements in the actual application scenario. The specific values of the first preset angle and the second preset angle are not limited in this embodiment. As a preferred implementation, the first preset angle can be 96°.

[0156] In the first embodiment of the present invention, the ballast cleaning device drives the sliding member to move on the support platform by shortening the push rod, thereby driving the connecting frame to move. By arranging a limit block on the swing arm support, the swing arm is kept in a vertical state. The connecting frame pulls the elastic member to make it stretch, thereby generating a pulling force on the swing arm and driving the execution assembly to level the ballast. When encountering a large-weight obstacle that cannot be pushed, the resistance received by the execution assembly exceeds the pulling force provided by the elastic member, causing the swing arm to rotate under the action of the obstacle, thereby avoiding damage to the device, and it can automatically return to the vertical state after passing through the obstacle. When encountering signal equipment or a turnout, the push rod extends and drives the sliding member to move on the support platform, thereby shortening the elastic member. The swing arm rotates to a horizontal state under the action of the connecting frame to avoid damaging devices such as cables and signals. Therefore, the present invention can realize continuous automatic ballast cleaning without stopping, and at the same time can reduce labor costs and improve the efficiency and safety performance of the operation process.

[0157] Embodiment Two

[0158] Figure 26 is a schematic structural diagram of the long rail car group provided by the second embodiment of the present invention.

[0159] On the basis of the above-mentioned first embodiment, the second embodiment of the present invention further provides a long rail car group 100, as Figure 26 shown. The long rail car group 100 includes a vehicle body 2 and the ballast cleaning device 1 in the first embodiment above.

[0160] Among them, ballast cleaning devices 1 are respectively arranged on both sides of the vehicle body 2. The ballast cleaning devices 1 are fixedly connected to the side beams 21 on both sides of the vehicle body 2. Specifically, the push rod seat 101, the support platform 201, and the swing arm support 401 are welded and fixed to the side beam 21. The two ballast cleaning devices 1 are symmetrically arranged along the center line of the vehicle body 2 to level the ballast on the outer sides of the two tracks at the same time.

[0161] It should be noted that a lock seat (not shown in the figure) is also arranged on the side beam 21. When the long rail car group 100 stops operating, the swing arm 402 of the ballast cleaning device 1 is connected to the lock seat. For example, the swing arm 402 can be fixedly connected to the lock seat through a round pin and a split pin.

[0162] In addition, a control console can also be arranged on the vehicle body 2, and the control console is used to control the lowering and retracting of the ballast cleaning device 1.

[0163] Other technical features are the same as those in the first embodiment and can achieve the same technical effects, and will not be elaborated here one by one.

[0164] The long rail vehicle group provided in the second embodiment of the present invention includes a vehicle body and a ballast cleaning device. The ballast cleaning device drives a sliding member to move on a support platform by shortening a push rod, thereby driving a connecting frame to move. By providing a limit block on a swing arm support, the swing arm is kept in a vertical state. The connecting frame pulls an elastic member to make it elongate, thereby generating a pulling force on the swing arm and driving an execution assembly to level the ballast. When encountering a large-weight obstacle that cannot be pushed, the resistance received by the execution assembly exceeds the pulling force provided by the elastic member, causing the swing arm to rotate under the action of the obstacle, thereby avoiding damage to the device, and it can automatically return to the vertical state after passing the obstacle. When encountering a signal device or a turnout, the push rod elongates and drives the sliding member to move on the support platform, thereby shortening the elastic member, and the swing arm rotates to a horizontal state under the action of the connecting frame to avoid damaging devices such as cables and signals. Therefore, the present invention can realize continuous automatic ballast cleaning without stopping, and at the same time can reduce labor costs and improve the efficiency and safety performance of the operation process.
