Description

Technical Field

[0001] This utility model belongs to the field of railway track maintenance technology, specifically relating to a track side ballast leveling and track center ballast filling machine. Background Technology

[0002] In the field of railway track maintenance, the ballast bed, as a crucial component of the track structure, directly affects the safety and smoothness of train operation. Long-term exposure to train dynamic loads and environmental factors makes ballast prone to displacement, breakage, or loss, especially in the center area between sleepers, where ballast loss is more pronounced. Traditional ballast replenishment operations rely heavily on manual labor or semi-mechanized equipment, resulting in low efficiency and uneven ballast distribution. With the increasing load on railway transportation, the demand for efficient and precise ballast replenishment technology is becoming increasingly urgent.

[0003] In the prior art, invention patent CN116254729A discloses a track center ballast filling machine, which uses chain-driven ballast hooks to grab ballast stones. As the traveling frame moves, the ballast hooks reciprocate to perform ballast grabbing, conveying, and filling actions. The ballast hooks on the chain are not continuous, with gaps in between. Therefore, the intermittent movement of the ballast hooks easily leads to uneven ballast distribution. Especially during the equipment's movement, the cycle of the ballast hooks and the moving speed of the traveling frame are difficult to precisely match, causing ballast stone accumulation or missed filling. Furthermore, the uneven grabbing of ballast stones on the track side by the ballast hooks easily exacerbates the fluctuation of ballast stones on the track side. Utility Model Content

[0004] This invention aims to solve the problem of uneven ballast filling and disruption of the ballast stones on the side of the track in existing track filling machines.

[0005] This utility model provides the following technical solution: a track side ballast leveling and center ballast replenishment machine, including a track vehicle, a U-shaped screw conveyor, and a toothed roller; the toothed roller is parallel to the U-shaped screw conveyor and along the forward direction of the track vehicle, and is located in front of the U-shaped screw conveyor; the toothed roller includes a central roller shaft and a row of teeth arranged in a ring around the roller shaft; a toothed shovel plate is provided on the side of the U-shaped screw conveyor near the toothed roller, the bottom end of the toothed shovel plate can be inserted into the ballast on the track side, and the top end of the toothed shovel plate is fixed to the top inlet edge of the U-shaped screw conveyor; the teeth of the toothed shovel plate and the teeth of the toothed roller are staggered, so that the toothed roller can pass through the toothed shovel plate and push the ballast scooped up by the toothed shovel plate into the U-shaped screw conveyor; the discharge port of the U-shaped screw conveyor is located at the center of the track.

[0006] Furthermore, a first motor reducer assembly is installed at the upper end of the U-shaped screw conveyor. The first motor reducer assembly is connected to the upper end of the screw conveyor shaft of the U-shaped screw conveyor. The lower end of the screw conveyor shaft passes through the housing of the U-shaped screw conveyor and is connected to the drive pulley. The lower end of the comb roller shaft is connected to the driven pulley. The drive pulley and the driven pulley are connected by a belt.

[0007] Furthermore, the two ends of the comb roller shaft are mounted on bearing brackets, which are fixed to the housing of the U-shaped screw conveyor.

[0008] Furthermore, a swing frame is fixed on the casing of the U-shaped screw conveyor. The swing frame is hinged to the railcar, and two hydraulic cylinders connect the swing frame and the railcar.

[0009] Furthermore, the railcar includes a frame and two sets of front and rear rail wheelsets. A driven sprocket is connected to the axle of the rear rail wheelset. A second motor reducer set is installed on the frame. A driving sprocket is installed on the output shaft of the second motor reducer set. The driving sprocket and the driven sprocket are connected by a chain.

[0010] Furthermore, a battery is also installed on the frame, with the battery and the second motor reducer assembly located on the side away from the U-shaped screw conveyor.

[0011] Furthermore, a guide plate is installed on the discharge port of the U-shaped screw conveyor.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] This utility model provides a track side ballast leveling and core ballast replenishment machine, which uses a comb tooth shovel plate in conjunction with a comb tooth roller for ballast leveling and a spiral conveyor for directional ballast replenishment. It solves the problem of uneven ballast distribution in traditional equipment, and has the advantages of high efficiency, precision and economy. It is suitable for track bed maintenance needs in various scenarios such as railway trunk lines, heavy-load lines and complex slopes.

[0014] The comb teeth of the comb roller are staggered with the comb tooth shovel plate. Through continuous rotation, the ballast on the side of the track is evenly scraped (ballast leveling) and precisely fed into the U-shaped screw conveyor. The U-shaped screw conveyor lifts the ballast to the center of the track through the screw conveyor shaft. The guide plate at the discharge port controls the landing point of the ballast, realizing continuous and uniform ballast replenishment in the center area and filling the problem of ballast accumulation or voids caused by intermittent feeding in traditional grab bucket equipment.

[0015] The bottom end of the comb-tooth shovel plate fits tightly against the track bed, automatically maintaining a consistent ballast depth as the track vehicle moves, reducing the need for manual intervention. Attached Figure Description

Detailed Implementation

[0022] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0023] like Figures 1-5 As shown, a track side ballast leveling and track center ballast filling machine includes a track vehicle 1, a U-shaped screw conveyor 2, and a comb roller 3;

[0024] The comb roller 3 is parallel to the U-shaped screw conveyor 2 and is located in front of the U-shaped screw conveyor 2 along the forward direction of the railcar 1.

[0025] The comb roller 3 includes a central roller shaft 3.1 and comb tooth rows 3.2 arranged in a ring around the roller shaft 3.1. Each comb tooth row 3.2 consists of comb teeth distributed at equal intervals. The spacing between the comb teeth is smaller than the average particle size of the ballast.

[0026] A comb tooth shovel plate 4 is provided on one side of the U-shaped screw conveyor 2 near the comb tooth roller 3. The bottom end of the comb tooth shovel plate 4 is flush with or lower than the bottom of the U-shaped screw conveyor 2, that is, the bottom end of the comb tooth shovel plate 4 can be inserted into the ballast. The top end of the comb tooth shovel plate 4 is fixed to the top inlet edge of the U-shaped screw conveyor 2, that is, the top end of each comb tooth of the comb tooth shovel plate 4 is fixedly connected to the U-shaped screw conveyor 2. The comb tooth shovel plate 4 intersects with the comb tooth row 3.2 of the comb tooth roller 3. The comb teeth of the comb tooth shovel plate 4 and the comb teeth of the comb tooth roller 3 are staggered, so that the comb tooth row 3.2 can pass through the comb tooth shovel plate 4.

[0027] As the track car 1 moves forward, the bottom of the toothed shovel plate 4 scoops up the ballast. As the toothed roller 3 continues to rotate, the toothed row 3.2 of the toothed roller 3 pushes the ballast along the toothed shovel plate 4 into the U-shaped screw conveyor 2. The U-shaped screw conveyor 2 lifts the ballast upward. The discharge port 2.1 of the U-shaped screw conveyor 2 is located at the center of the track, and the ballast falls from the discharge port 2.1 onto the center of the track.

[0028] A guide plate 16 is installed on the discharge port 2.1 to guide the falling ballast and prevent it from splashing everywhere.

[0029] The railcar 1 travels on the rails. The railcar 1 travels along a stable route, so the toothed shovel 4 smoothly sweeps across the ballast on the side of the rail, flattening the ballast and achieving the effect of uniform ballast application.

[0030] The comb roller 3 utilizes the power of the U-shaped screw conveyor 2. The upper end of the U-shaped screw conveyor 2 is equipped with a first motor reducer 5, which is connected to the upper end of the screw conveyor shaft 2.2 of the U-shaped screw conveyor 2, driving the screw conveyor shaft 2.2 to rotate. The lower end of the screw conveyor shaft 2.2 passes through the housing of the U-shaped screw conveyor 2 and is connected to the drive pulley 6. The lower end of the roller shaft 3.1 of the comb roller 3 is connected to the driven pulley 7. The drive pulley 6 and the driven pulley 7 are connected by a belt 8, so that when the first motor reducer 5 drives the screw conveyor shaft 2.2 to rotate, it drives the comb roller 3 to rotate.

[0031] Specifically, the comb roller 3 is connected to the U-shaped screw conveyor 2; the two ends of the roller shaft 3.1 of the comb roller 3 are mounted on the bearing bracket 9, and the bearing bracket 9 is fixed on the housing of the U-shaped screw conveyor 2.

[0032] A swing frame 10 is fixed on the shell of the U-shaped screw conveyor 2. The swing frame 10 is hinged to the railcar 1. Two hydraulic cylinders 11 are connected between the swing frame 10 and the railcar 1. The two hydraulic cylinders 11 drive the swing frame 10 to swing, changing the angle of the U-shaped screw conveyor 2 and the comb roller 3 to adapt to the slope on both sides of the track.

[0033] The railcar 1 includes a frame 1.1 and two sets of front and rear rail wheelsets 1.2. A driven sprocket 12 is connected to the axle of the rear rail wheelset 1.2. A second motor reducer group 17 is installed on the frame 1.1. A drive sprocket 13 is installed on the output shaft of the second motor reducer group 17. The drive sprocket 13 and the driven sprocket 12 are connected by a chain 14.

[0034] A battery 15 is also installed on the frame 1.1. The battery 15 and the second motor reducer group 17 are located on the side away from the U-shaped screw conveyor 2 and are used for counterweight. The battery 15 provides power for the movement of the railcar 1 and the operation of various components.

[0035] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
