Description

Technical Field

[0001] The present application relates to the field of railway vehicle shunting, and in particular to a railway vehicle traction device and a railway locomotive. Background Art

[0002] Railway vehicles can be divided into freight trains for transporting goods and passenger trains for carrying passengers according to their load. Railway vehicles can generally be divided into the locomotive part and the carriage part. For freight trains, the power for their operation is provided by the locomotive part, and the carriage part moves along the rails under the traction of the locomotive part.

[0003] Freight trains need to be loaded and unloaded in ports, mines and freight yards. During the operation, freight trains are required to move slowly in the loading and unloading area. Since the manufacturing cost and use cost of the front part are high, in order to improve the utilization rate of the front part and reduce the use cost, after the freight train moves to the above-mentioned area, the front part will be separated from the carriage part and leave. The movement of the carriage part in the loading and unloading area is completed by other traction equipment.

[0004] At present, the Chinese invention patent application with the announcement number CN113002252A discloses a dual-purpose tractor for road and rail, including a front drive device, fixed on the chassis of the vehicle body, the front drive device includes two first steel wheels for simultaneously realizing both driving and guiding; a steering device, fixed on the chassis of the vehicle body, the steering device includes two first rubber wheels for realizing steering; a rear drive device, fixed on the chassis of the vehicle body, the rear drive device includes a plurality of second rubber wheels for realizing driving; a guiding device, fixed on the chassis of the vehicle body, the guiding device includes two second steel wheels for realizing guiding. The first steel wheel is both guiding and driving like the steel wheel of a train, and the steering rubber wheel does not contact the rail, so the tractor will not fall off the rail, the two first steel wheels and the rear drive device (2, 4 or 6 driving rubber wheels) are mixedly driven to increase the traction force, and the rear driving rubber wheel can be increased or decreased according to the weight of the traction cargo, and the front and rear ends of the vehicle body are provided with a weight-aiding force-increasing system to greatly increase the traction weight.

[0005] With respect to the above-mentioned related technologies, the inventors believe that the weight of the tractor provides the positive pressure required for the friction drive between the wheels and the rails, and the maximum traction it can provide depends on the weight of the conventional tractor and the friction coefficient between the wheels and the rails of the conventional tractor. Since the friction coefficient between the wheels and the rails is difficult to increase, the improvement of traction can only be achieved by increasing the weight of the tractor. Under the demand for high traction, there is a defect that the manufacturing cost and the use cost of the tractor are increasingly high. Summary of the invention

[0006] In order to alleviate the problem that improving the traction force of a tractor will increase the use cost and manufacturing cost, the present application provides a railway vehicle traction device.

[0007] The present application provides a railway vehicle traction device, which adopts the following technical solution:

[0008] A railway vehicle traction device comprises a frame, a moving mechanism, a frame positioning mechanism, a traction mechanism and a traction rope guiding mechanism, wherein the moving mechanism is connected to the frame, the frame moves along the rails through the moving mechanism, the frame positioning mechanism is connected to the frame, the frame positioning mechanism is used to limit the movement of the frame along the rails, the traction mechanism is connected to the frame, the traction mechanism is used to traction the carriage part of a freight train to move, the traction rope guiding mechanism is arranged on a side of the frame close to the carriage part, the traction rope guiding mechanism is connected to the rails, the traction rope guiding mechanism is connected to the frame through a connecting rod, one end of the connecting rod is hinged to the frame, the other end of the connecting rod is connected to the traction rope guiding mechanism, and the traction rope guiding mechanism is used to adjust the extension direction of the traction rope of the traction mechanism.

[0009] By adopting the above technical scheme, when the carriage part of the freight train is towed, in the forward direction of the carriage part, the moving mechanism is used to drive the frame to move along the rails in the direction away from the carriage part. As the frame moves, the traction mechanism connected to the frame unwinds the traction rope. When the frame moves a set length, the moving mechanism stops working, the frame is positioned by the frame positioning mechanism to limit the movement of the frame along the rails, and the traction mechanism reels in the traction rope. During the rewinding of the traction rope, the carriage part is driven to move in the direction close to the frame. The traction rope guide mechanism is used to adjust the extension direction of the traction rope, so that when the traction mechanism is towing the carriage part, the traction rope remains horizontal between the traction mechanism and the traction rope guide mechanism. The traction force applied by the tractor to the carriage part is determined by the pulling force applied by the traction mechanism to the traction rope, thereby reducing the influence of the traction vehicle's own weight on the traction force, and alleviating the problem that the traction force of the tractor will increase the use cost and manufacturing cost.

[0010] Optionally, the frame positioning mechanism includes a mounting plate, a positioning assembly, a lifting assembly and a distance detection sensor, the mounting plate is connected to the frame through the lifting assembly, the lifting assembly drives the mounting plate to move in a direction close to or away from the ground, the traction mechanism is arranged on the side of the mounting plate away from the ground, the positioning assembly is arranged on the side of the mounting plate close to the ground, the positioning assembly includes two positioning columns, the two positioning columns are arranged along the width direction of the frame, the positioning columns are fixedly connected to the mounting plate, the positioning columns are used to abut against the side walls of the rail sleepers, the distance detection sensor is arranged on the side of the mounting plate close to the ground, the distance detection sensor is located between the two positioning columns, and the distance detection sensor is electrically connected to the moving mechanism.

[0011] By adopting the above technical scheme, when the frame stops moving, the lifting assembly is used to drive the mounting plate to move in a direction close to the ground, so that the positioning column moves to one side of the rail sleeper. When the traction mechanism pulls the carriage part, the traction device moves in a direction close to the carriage part under the reaction force, so that the positioning column abuts against the side wall of the rail sleeper, thereby limiting the movement of the frame along the rail direction; during the movement of the frame, the distance detection sensor is used to detect the distance between the mounting plate and the ground. When the data detected by the distance detection sensor is less than the set value, the distance detection sensor transmits a signal to the moving mechanism, so that the moving mechanism continues to drive the frame to move, thereby reducing the possibility that the positioning column is located above the rail sleeper after the frame stops moving, thereby avoiding affecting subsequent work; in addition, two positioning columns are arranged along the width direction of the frame. After the positioning column abuts against the rail sleeper, the mounting plate is subjected to uniform force, thereby reducing the possibility of torsional stress between the mounting plate and the frame, thereby increasing the service life of the mounting plate.

[0013] By adopting the above technical solution, multiple groups of positioning components are arranged along the length direction of the frame. When positioning the frame, each group of positioning components abuts against the side wall of a rail sleeper, so that the force on the mounting plate is more uniform, thereby improving the stability of the frame positioning mechanism in positioning the frame.

[0020] By adopting the above technical solution, the wheel is made of high-strength permanent magnet material. When the carriage part is towed, the adhesion between the wheel and the rail is increased, thereby improving the working stability of the traction device; by arranging a rubber ring on the wheel and the rubber ring is located in the wheel groove, during the movement of the traction device, the rubber ring on the wheel abuts against the rail, thereby reducing the wear of the wheel and increasing the service life of the wheel.

[0022] In order to alleviate the problem that improving the traction force of a tractor will increase the use cost and manufacturing cost, the present application provides a railway locomotive.

[0023] The present application provides a railway locomotive, which adopts the following technical solution:

The data detected by the pressure detection sensor is used to determine whether the railway vehicle traction device is towing the carriage part. When the railway vehicle traction device stops traction, the pressure detection sensor transmits a signal to the braking mechanism, and the braking mechanism limits the movement of the carriage part, thereby reducing the possibility of the carriage part colliding with the railway vehicle traction device under the action of inertia.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] When the carriage part of the freight train is towed, in the forward direction of the carriage part, the moving mechanism is used to drive the frame to move along the rails in the direction away from the carriage part.

[0028] When the frame stops moving, the lifting assembly is used to drive the mounting plate to move in a direction close to the ground, so that the positioning column moves to one side of the rail sleeper. When the traction mechanism pulls the carriage part, the traction device moves in a direction close to the carriage part under the reaction force, so that the positioning column abuts against the side wall of the rail sleeper, thereby limiting the movement of the frame along the rail direction; during the movement of the frame, the distance detection sensor is used to detect the distance between the mounting plate and the ground. When the data detected by the distance detection sensor is less than the set value, the distance detection sensor transmits a signal to the moving mechanism, so that the moving mechanism continues to drive the frame to move, thereby reducing the possibility that the positioning column is located above the rail sleeper after the frame stops moving, thereby avoiding affecting subsequent work; in addition, two positioning columns are arranged along the width direction of the frame. After the positioning column abuts against the rail sleeper, the mounting plate is evenly stressed, thereby reducing the possibility of torsional stress between the mounting plate and the frame, thereby increasing the service life of the mounting plate;

[0029] By using wheels made of high-strength permanent magnet materials, the adhesion between the wheels and the rails is increased when the carriage is towed, thereby improving the working stability of the traction device; by arranging rubber rings on the wheels and the rubber rings are located in the wheel grooves, during the movement of the traction device, the rubber rings on the wheels abut against the rails, thereby reducing the wear on the wheels and increasing the service life of the wheels.

[0039] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present application is not limited by the specific embodiments disclosed below. It should be noted that the embodiments of the present application and the features in each embodiment may be combined with each other without conflict.

[0040] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a communication; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0041] The present application embodiment discloses a railway vehicle traction device. Figure 1 and Figure 2A railway vehicle traction device includes a frame 100, a moving mechanism 200, a frame positioning mechanism 300, a traction mechanism 400 and a traction rope guiding mechanism 500. The moving mechanism 200 is installed on the frame 100, and the frame 100 moves along the rail 600 through the moving mechanism 200. The frame positioning mechanism 300 is connected to the frame 100, and the frame positioning mechanism 300 is used to limit the movement of the frame 100 along the rail 600. The traction mechanism 400 is installed on the frame 100, and the traction mechanism 400 is used to traction the carriage part 800 of the freight train to move. The traction rope guiding mechanism 500 is located on the side of the frame 100 close to the traction carriage part 800, and the traction rope guiding mechanism 500 is installed on the rail 600. The traction rope guiding mechanism 500 is movably connected to the frame 100 through a connecting rod, and the traction rope guiding mechanism 500 is used to adjust the extension direction of the traction rope 410 of the traction mechanism 400.

[0042] When the carriage part 800 of the freight train is towed, the moving mechanism 200 is used to drive the frame 100 to move along the track in the direction away from the carriage part 800. As the frame 100 moves, the traction mechanism 400 connected to the frame 100 unwinds the traction rope 410. When the frame 100 moves a set length, the moving mechanism 200 stops working, and the frame positioning mechanism 300 is used to position the frame 100 to limit the movement of the frame 100 along the track. The traction mechanism 400 reels the traction rope 410. During the winding process, the carriage part 800 is driven to move toward the frame 100. The traction rope guiding mechanism 500 is used to adjust the extension direction of the traction rope 410 so that when the traction mechanism 400 is traction on the carriage part 800, the traction rope 410 is kept horizontal between the traction mechanism 400 and the traction rope guiding mechanism 500. The traction force applied by the tractor to the carriage part 800 is determined by the tension applied by the traction mechanism 400 to the traction rope 410, thereby reducing the influence of the tractor's own weight on the traction force, and alleviating the problem that the use cost and manufacturing cost of the tractor will increase when the traction force is increased.

[0043] Reference Figure 2 and Figure 3 The mobile mechanism 200 includes a driving assembly and a plurality of wheel 210 assemblies. The plurality of wheel 210 assemblies are arranged at intervals along the length direction of the frame 100. The wheel 210 assembly includes two wheels 210, which are respectively mounted on both sides of the length direction of the frame 100, and the two wheels 210 are connected by a transmission shaft. The driving assembly includes a driving motor, which is connected to one of the transmission shafts.

[0044] The wheel 210 is provided with a wheel groove 220 for cooperating with the rail 600 . The wheel groove 220 is provided along the circumference of the wheel 210 . The wheel groove 220 is located in the middle position of the axial direction of the wheel 210 . The wheel 210 is made of high-strength permanent magnetic material. A rubber ring 230 is sleeved on the wheel 210 . The rubber ring 230 is located in the wheel groove 220 .

[0045] The wheel 210 is made of a high-strength permanent magnet material. When the carriage part 800 is towed, the adhesion between the wheel 210 and the rail 600 is increased, thereby improving the working stability of the traction device; by sleeved with a rubber ring 230 on the wheel 210 and the rubber ring 230 being located in the wheel groove 220, during the movement of the traction device, the rubber ring 230 sleeved on the wheel 210 abuts against the rail 600, thereby reducing the wear of the wheel 210 and increasing the service life of the wheel 210.

[0046] Reference Figure 4 and Figure 5 The frame positioning mechanism 300 includes a mounting plate 310, a positioning assembly, a lifting assembly 330 and a distance detection sensor 340. The mounting plate 310 is connected to the frame 100 through the lifting assembly 330, and the lifting assembly 330 drives the mounting plate 310 to move in a direction close to or away from the ground. The traction mechanism 400 is installed on the side of the mounting plate 310 away from the ground, and the positioning assembly is installed on the side of the mounting plate 310 close to the ground.

[0047] The frame 100 is provided with a guide groove, which is provided along the moving direction of the mounting plate 310. A slider is fixedly connected to the side wall of the mounting plate 310, and the slider is slidably connected in the guide groove. A connecting seat 332 is fixedly connected to the side of the mounting plate 310 away from the ground, and a connecting groove 333 is provided on the connecting seat 332, and the connecting groove 333 is provided along the length direction of the frame 100. The lifting assembly 330 includes an electric push cylinder 331, the cylinder body of the electric push cylinder 331 is fixedly connected to the frame 100, and a connecting block 334 is fixedly connected to the piston rod of the electric push cylinder 331, and the connecting block 334 is slidably connected in the connecting groove 333.

[0048] The positioning assembly includes two positioning columns 320, which are arranged along the width direction of the frame 100. The positioning columns 320 are fixedly connected to the mounting plate 310. The positioning columns 320 are used to abut against the side walls of the rail sleepers 700. The positioning columns 320 and the mounting plate 310 are integrally formed to improve the structural strength of the connection between the positioning columns 320 and the mounting plate 310, thereby improving the stability of the positioning of the frame 100.

[0049] The distance detection sensor 340 is disposed on a side of the mounting plate 310 close to the ground. The distance detection sensor 340 is used to detect the distance between the mounting plate 310 and the ground. The distance detection sensor 340 is electrically connected to the driving motor.

[0050] There are multiple groups of positioning components, which are spaced apart along the length direction of the frame 100. The distance between two adjacent groups of positioning components is equal to the distance between two adjacent rail sleepers 700. The distance detection sensor 340 is located between two positioning columns 320 of one group of positioning components.

[0051] When the vehicle frame 100 stops moving, the electric push cylinder 331 is used to drive the mounting plate 310 to move toward the ground, so that the positioning column 320 moves to one side of the rail sleeper 700. When the traction mechanism 400 pulls the car body part 800, the traction device moves toward the car body part 800 under the reaction force, so that the positioning column 320 abuts against the side wall of the rail sleeper 700, thereby limiting the movement of the vehicle frame 100 along the track direction.

[0052] During the movement of the vehicle frame 100, the distance detection sensor 340 is used to detect the distance between the mounting plate 310 and the ground. When the data detected by the distance detection sensor 340 is less than the set value, the distance detection sensor 340 transmits a signal to the drive motor, so that the drive motor continues to drive the vehicle frame 100 to move, thereby reducing the possibility that the positioning column 320 is located above the railroad sleeper 700 after the vehicle frame 100 stops moving, thereby avoiding affecting subsequent work. In addition, two positioning columns 320 are set along the width direction of the vehicle frame 100. After the positioning columns 320 abut against the railroad sleeper 700, the mounting plate 310 is evenly stressed, thereby reducing the possibility of torsional stress between the mounting plate 310 and the vehicle frame 100, thereby increasing the service life of the mounting plate 310.

[0053] Reference Figure 2 and Figure 4 By setting a plurality of positioning components along the length direction of the frame 100, when positioning the frame 100, each positioning component abuts against the side wall of a rail sleeper 700, so that the force on the mounting plate 310 is more uniform, thereby improving the stability of the frame positioning mechanism 300 in positioning the frame 100.

[0054] Reference Figure 5 The piston rod of the electric push cylinder 331 is movably connected to the mounting plate 310 through the cooperation of the connecting block 334 and the connecting groove 333, thereby reducing the possibility of bending stress generated between the piston rod of the electric push cylinder 331 and the cylinder body when the positioning mechanism is working, thereby improving the service life of the electric push cylinder 331; the mounting plate 310 is slidably connected to the frame 100 along the height direction of the frame 100 through the cooperation of the guide block and the guide groove, thereby limiting the movement of the mounting plate 310 along the length direction of the frame 100, thereby improving the working stability of the mounting plate 310.

[0055] Reference Figure 1 and Figure 6The traction rope guide mechanism 500 includes a mounting platform 510, a guide pulley 520, a plurality of rollers 530 and a plurality of limiting wheels 540.
