Description

Technical Field

[0001] This utility model relates to the field of railway maintenance tools, and in particular to a ballast limiting device for railway track slopes. Background Technology

[0002] As a vital national transportation infrastructure, the stability and safety of railways directly impact train operation efficiency and passenger safety. In railway track structures, the ballast laid beneath and on both sides of the sleepers is a crucial component ensuring track stability. The stones beneath the sleepers serve as the roadbed, reducing vibration and minimizing damage to the track surface. However, the stones must be laid below the level of the rails, not exceeding a certain height; otherwise, they could be lifted by passing trains, striking maintenance workers nearby or trains on adjacent tracks, causing accidents.

[0003] Traditional ballast height control relies on manual leveling. This involves multiple workers using rakes, shovels, and other tools to manually level the ballast along both sides of the track, visually assessing whether the ballast height meets standards. This manual leveling method is slow, and for long-distance railway lines, it often requires a large number of workers working continuously to maintain a section of the line. This is insufficient to meet the rapid maintenance needs of modern railway operations and hinders the improvement of leveling efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a ballast limiting device for railway track slopes, which aims to overcome the problems of low efficiency and high labor costs in the traditional method of manually leveling ballast on railway slopes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a ballast limiting device for railway track slope, comprising a support frame, the support frame being T-shaped, with limiting arms detachably connected to both the left and right sides of the support frame, a level fixed horizontally at the end of the limiting arm, a push rod fixedly connected to the middle of the support frame, bearing seats fixedly connected to the front and rear sides of the lower left end and the lower right end of the support frame, a guide wheel that can roll on the rail being connected to the inner wall of the bearing seat via a rotating shaft, and a limiting mechanism fixed to the left side of the support frame;

[0006] The limiting mechanism includes a mounting base fixedly connected to the lower part of the support frame. A limiting component is slidably connected to the inner wall of the mounting base. A screw is threadedly connected to the upper part of the limiting component. An anti-slip component is threadedly connected to the screw. A connecting component is rotatably connected to the lower part of the screw. The connecting component is fixedly connected to the upper part of the support frame.

[0007] Furthermore, the limiting member is U-shaped.

[0008] Furthermore, a rotating cylinder is rotatably connected to the middle of the limiting member.

[0009] Furthermore, the ends of both sets of limiting arms away from the support frame are bent upwards, and the level is fixed to the upper side of the bent portion.

[0010] Furthermore, the support frame is provided with a drive assembly, which includes three sets of synchronously rotating flywheels. Two sets of flywheels are coaxially connected to the shafts of the two sets of guide wheels on the left side, and the other set of flywheels is connected to the support frame through a support base and coaxially connected to the drive motor. The drive motor is fixed on the support frame.

[0011] Furthermore, the three sets of flywheels are connected via the same chain drive.

[0012] Furthermore, a battery compartment is fixed in the middle of the support frame, and the battery in the battery compartment is electrically connected to the drive motor.

[0013] Furthermore, a controller is fixed on the push rod, and the drive motor is electrically connected to the controller.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. Compared with the traditional method of manually leveling ballast on slopes, which requires a large number of workers, this utility model can conveniently complete the height limiting and leveling of ballast through the limiting arm, greatly reducing the number of workers required and lowering labor costs. It can be driven forward by a motor through the drive component or manually pushed by a push rod. Both movement methods can quickly move along the track. Compared with manual leveling, it significantly improves the operation speed and meets the needs of rapid maintenance under the modern operation of railways.

[0016] 2. In this utility model, the limiting member can be moved up and down to adjust to a suitable position. When the device moves on the rail, the crossbar at the bottom of the limiting arm will flatten any stones that exceed the height. When the limiting arm is hit by stones, the limiting member can maintain the stability of the device and prevent it from falling off the rail, thus improving the stability of the device.

[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figures 1 to 3 This utility model provides a ballast limiting device for railway track slopes, including a support frame 1. The support frame 1 is T-shaped and serves as the core load-bearing structure, used to connect and fix other components. Its rigid structure disperses the impact force during operation, ensuring the overall stability of the device. Limiting arms 4 are bolted to the inner walls of both sides of the support frame 1, sliding inside the support frame 1 and adjustable in length. These arms can directly contact and flatten protruding ballast on the track slope, pushing ballast exceeding a specified height below the target height. The two sets of limiting arms 4 are located away from the support frame 1. One end is bent upwards, and a level 5, which is a bubble level, is fixed horizontally at the end of the limiting arm 4. It is used to monitor the horizontal status of the device in real time and help the operator adjust the balance of the device in time. A push rod 6 is fixedly connected in the middle of the support frame 1. It can be used as a gripping part for manually pushing the device and also provides an installation position for the controller, so that the operator can control it in real time. Bearing seats 2 are fixedly connected to the front and rear sides of the lower left end and the lower right end of the support frame 1. They provide a stable installation base for the guide wheel 3 and limit the displacement of the guide wheel 3 to ensure that it rolls along the direction of the rail.

[0024] Reference Figures 1 to 3The inner wall of the bearing housing 2 is connected to a guide wheel 3 that can roll on the rail via a rotating shaft, ensuring that the device moves along the rail and reducing the frictional resistance between the device and the rail, making the movement smoother. The left side of the support frame 1 is fixed with a limiting mechanism 8. The limiting mechanism 8 includes a mounting seat 81 fixedly connected to the lower part of the support frame 1, providing a sliding channel for the limiting member 82, restricting it to move only in the vertical direction. The inner wall of the mounting seat 81 is slidably connected to the limiting member 82. The limiting member 82 is U-shaped, and a rotating cylinder is rotatably connected to the middle of the limiting member 82 via a screw 8. 3. After adjusting the height, it fits against both sides of the rail, providing lateral support when the device is impacted; the rotating drum can reduce friction with the rail, and the limiting member 82 is threadedly connected to the screw 83. When rotated, it can drive the limiting member 82 to slide up and down along the mounting base 81 to achieve height adjustment. The screw 83 is threadedly connected to the anti-slip member 84. After being tightened with the limiting member 82, it can lock the position of the limiting member 82 to prevent it from shifting due to vibration or impact during operation. The lower part of the screw 83 is rotatably connected to the connecting member 85, which is fixedly connected to the support frame 1.

[0025] Reference Figures 1 to 3 The support frame 1 is equipped with a drive assembly 7, which includes three sets of synchronously rotating flywheels 71. Each flywheel 71 has a ratchet mechanism inside. Two sets of flywheels 71 are coaxially connected to the rotating shafts of the two guide wheels 3 on the left side. The third set of flywheels 71 is connected to the support frame 1 via a support base 74 and coaxially connected to a drive motor 75. The drive motor 75 is fixed to the support frame 1 and drives the guide wheels 3 to rotate via the flywheels 71 and a chain 72, thus enabling the device to move. The three sets of flywheels 71 are connected by the same chain 72, transmitting the power of the drive motor 75 to the rotating shafts of the guide wheels 3, causing them to rotate and enabling the device to move using the motor. A battery compartment 73 is fixed in the middle of the support frame 1, with a built-in battery providing power to the drive motor 75 and the controller, freeing the device from external power supply limitations and making it suitable for environments without power supply, such as in the field. A controller is fixed on the push rod 6 to control the start, stop, speed adjustment, and pause of the drive motor 75, achieving automated movement control of the device and improving operational convenience.

[0026] In use, this utility model is placed on the rail, with the guide wheel 3 in contact with the rail. Then, the screw 83 in the limiting mechanism 8 is rotated, driving the U-shaped limiting member 82 to slide up and down along the mounting base 81, adjusting it to a position suitable for both sides of the rail. The anti-slip member 84 is tightened to lock the height of the limiting member 82, preventing displacement due to vibration or impact during operation. The horizontal status of the device can be observed through the level 5 on the outside of the limiting arm 4. This device supports two movement modes, which can be switched between manual pushing and motor driving via the controller on the push rod 6.

[0027] In motor-driven mode, the battery in battery compartment 73 powers drive motor 75. The controller starts drive motor 75, and its output shaft drives upper flywheel 71 to rotate. Upper flywheel 71 drives two other sets of flywheels 71 to rotate synchronously via chain 72, which in turn drives guide wheel 3 to roll along the rail, enabling the device to move automatically. Flywheel 71 has a built-in ratchet mechanism to ensure that power is transmitted in only one direction when the motor is driven.

[0028] When manually pushing, the drive motor 75 is turned off, the operator holds the push rod 6 to push the device, the guide wheel 3 rolls along the rail, and the ratchet mechanism of the flywheel 71 rotates freely, which does not affect manual movement.

[0029] When the device moves, the limiting arms 4 on both sides directly contact the ballast on the track slope. Due to the height limitation of the limiting arms 4, ballast exceeding the specified height is pushed down to below the target height. When the limiting arms 4 are hit by ballast, the limiting member 82 is tightly connected to the support frame 1 through the mounting base 81, providing lateral support force. Together with the T-shaped support frame 1, this prevents the device from shaking or derailing.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
