Description

Technical Field

[0001] This invention relates to the field of auxiliary equipment for moving rail vehicles, and more particularly to a hand-operated train carriage booster device. Background Technology

[0002] In railway vehicle dispatching and maintenance, it is often necessary to move single or multiple detached carriages short distances to designated maintenance positions or for regrouping. Currently, such movements mostly rely on manual pushing, which requires multiple people working together. Furthermore, due to the large mass of the train carriages and the high static friction between the wheels and the rails, the pushing process is extremely strenuous, resulting in low efficiency. In addition, manual pushing makes it difficult to precisely control the direction and speed of the carriages, posing safety risks such as slippage and derailment, especially in confined spaces or with complex track conditions, further increasing the operational difficulty.

[0003] Therefore, existing technologies lack a dedicated device that is structurally sound, easy to operate, and capable of stable and labor-saving short-distance movement of train carriages. It is necessary to propose a hand-operated train carriage propulsion device to overcome the shortcomings of the aforementioned manual pushing methods and improve the efficiency, safety, and controllability of shunting operations. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention proposes a hand-operated train carriage propulsion device. This device mounts the entire mechanism on top of the rails, ensuring that the movement of the carriage does not obstruct the normal passage of other railway lines. Simultaneously, this invention innovatively incorporates a contoured groove at one end of the drive wheel and adds a rubber coating layer to the drive wheel, increasing the contact area and friction coefficient between the train wheel and the drive wheel. This effectively solves the slippage problem between the train wheel and the drive wheel, achieving efficient transmission between them.

[0005] This invention proposes a hand-operated train carriage booster device, comprising a handrail, a connecting plate, and a booster. The booster includes a power output unit, a chain drive mechanism, a baffle frame, a push wheel assembly, and support wheels. The power output unit is located on the inner side of the baffle frame, and the chain drive mechanism is located on the outer side. The output shaft of the power output unit is connected to the chain drive mechanism. The push wheel assembly is located on the lower inner side of the baffle frame, and both ends of the push wheel assembly are movably connected to the baffle frame. A handrail is located on the upper outer side of the baffle frame. The handrail is adjustablely fixed to the baffle frame through a slotted hole on the upper part of the baffle frame, allowing the operator to adjust the height and angle of the handrail according to their height and operating habits to obtain the optimal operating posture and prevent upper limb fatigue.

[0006] It should be noted that, unless otherwise stated, "connection" and "installation" in this application refer to rigid fixing (such as copper pillars, bolts, or key connections). "Transverse" refers to the direction perpendicular to the direction of travel of the hand-operated train car propulsion device in the horizontal plane.

[0007] The support wheel is rotatably mounted on the rear side of the power output unit to provide stable rear-end support for the entire device, allowing it to be placed securely on the rails.

[0008] The drive wheel assembly is located below the inner side of the baffle frame, and its two ends are rotatably connected to the baffle frame. The drive wheel assembly includes one drive wheel and two auxiliary wheels. The two auxiliary wheels are located on the left and right sides below the drive wheel, respectively, and the rims of the auxiliary wheels overlap with the rims of the drive wheel, increasing the stability of the device when running on the rail. The outer circumferential surface of the drive wheel directly abuts against the outer circumferential surface of the train wheel and drives the train wheel to rotate through friction, serving as the final actuator for transmitting thrust. It should be noted that the drive wheel has a specially shaped contoured groove at its end near the inner side of the rail. The shape of this groove perfectly conforms to the shape of the train wheel, thereby increasing the contact area and friction, effectively preventing slippage and protecting the wheel tread.

[0009] The chain drive mechanism includes two driving sprockets, two driven sprockets, and a chain. The driving sprockets are coaxially connected to the output shaft of the power output unit, and the driven sprockets are located in front of the driving sprockets and coaxially connected to the auxiliary sprockets in the drive wheel assembly. The chain is sleeved and installed outside the driving and driven sprockets, transmitting power from the power output unit to the auxiliary sprockets.

[0010] The drive wheel and auxiliary wheel each include a rubber coating and an axle body. The rubber coating is fitted onto the outside of the axle body, and both ends of the axle body are inserted into holes in the baffle frame, forming a rotating mechanism. This ensures sufficient friction, provides cushioning and protection for the train wheels, and also gives the drive wheel and auxiliary wheel sufficient strength.

[0011] It should be noted that the two booster devices are distributed symmetrically on both sides and are fixed to the upper surface of the connecting plate in a laterally adjustable manner. This structure allows the device to adapt to different car sizes and track gauges. By adjusting the width between the two booster devices, it is ensured that the drive wheel can be accurately aligned with and press against the wheels on both sides of the car.

[0012] Technical Effects: This invention provides a hand-operated train carriage propulsion device suitable for moving and propelling various train carriages, especially the C70 type general-purpose open wagon and various train carriages derived from the C70 type open wagon. The drive wheel has grooves that mate with the wheels of the C70 type open wagon, achieving a good transmission effect between the wheels and the hand-operated train carriage propulsion device, enabling the carriage to move even when the C70 type open wagon is fully loaded. Furthermore, the hand-operated train carriage propulsion device only occupies the space above the rails during operation, without affecting the normal passage of other railway lines.

[0024] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that these embodiments are only used to illustrate the technical solutions of the present invention and should not be construed as limiting the present invention.

[0025] It should be noted that the same reference numerals may be used repeatedly in different examples of this invention. This repetition is only for the purpose of brevity and clarity of expression and does not in itself indicate a specific relationship between the different embodiments and / or settings described.

[0026] See Figures 1 to 4 This invention provides a hand-operated train carriage booster device, including a handrail 2, a connecting plate 11, a chain drive mechanism 6, and booster devices 1. Two booster devices 1 are symmetrically distributed on the left and right sides of the connecting plate 11 and are fixed to the upper surface of the connecting plate 11 in a left-right adjustable manner.

[0027] See Figures 1 to 6 The booster device 1 includes a power output unit 5, a chain drive mechanism 6, a baffle frame 7, a push wheel assembly 13, and a support wheel 14. The support wheel 14 is rotatably mounted on the rear side of the power output unit 5. Specifically, it can be connected to a bearing seat at the rear of the baffle frame 7 via a shaft connection or similar means. The power output unit 5 is located on the inner side of the baffle frame 7, and its output shaft is connected to the chain drive mechanism 6. Specifically, the power output unit 5 can be fixed to the baffle frame 7 via bolts or similar connections, and the chain drive mechanism 6 can be fixed to the output shaft of the power output unit 5 via a key connection or similar means.

[0028] See Figure 2 The handrail 2 is a detachable and rotatable structure. Specifically, it can be installed on the circular elongated hole at the upper end of the baffle frame 7 via bolts or other connections, facilitating disassembly. It should be noted that when adjusting the tilt angle of the handrail 2, loosen the bolt connection in the elongated hole, press down or lift to adjust the tilt angle, and then retighten the bolt connection after adjusting to the specified angle.

[0029] See Figure 2 and Figure 5The drive wheel assembly 13 includes a drive wheel 3 and two auxiliary wheels 4. The auxiliary wheels 4 are installed horizontally parallel to each other inside the baffle frame 7 at its lower part. Specifically, a rotating structure can be formed by inserting the axle ends of the auxiliary wheels 4 into the holes of the baffle frame 7. The drive wheel 3 is positioned above the auxiliary wheels 4, and both ends of the drive wheel 3 are connected to the inside of the baffle frame 7. It should be noted that the distance between the axis of the drive wheel 3 and the axis of the auxiliary wheels 4 is less than the sum of the radii of the two wheels, so that the rims of the drive wheel 3 and the auxiliary wheels 4 have a certain degree of overlap, which can increase the friction between the drive wheel 3 and the auxiliary wheels 4.

[0030] See Figures 1 to 7 The drive wheel 3 has a contoured groove 12 on its inner side at one end near the inner side of the rail. It should be noted that the shape of the groove 12 is determined by the point cloud data obtained after three-dimensional scanning of the train wheel, which enables the drive wheel 3 to fit the wheel, making it less prone to slippage, more tightly fitted, and providing a better boosting effect.

[0031] See Figures 1 to 6 It should be noted that the circumferential surfaces of the auxiliary wheel 4 and the support wheel 14 are supported on the top surface of the rail to provide forward friction and support force for squeezing the wheel when the wheel is being pushed to move.

[0032] See Figure 2 and Figure 3 The chain drive mechanism 6 is located on the outer side of the middle of the baffle frame 7, and includes a drive sprocket 8, a driven sprocket 10, and a chain 9. The motor output shaft of the power output unit 5 is connected to the center hole of the drive sprocket 8. The drive sprocket 8 and the driven sprocket 10 are arranged front and rear, and the chain 9 is sleeved on the outside of both sprockets to form the chain drive mechanism. Specifically, the driven sprocket 10 and the auxiliary wheel 4 located behind it can be connected by a coupling or other connection method. When the power output unit 5 is started, its motor output shaft drives the drive sprocket 8 at the rear to rotate, and through the transmission action of the chain 9, it simultaneously drives the driven sprocket 10 at the front to rotate, thereby providing transmission power for the rotation of the drive wheel 3.

[0033] See Figure 2 , Figure 3 and Figure 9 The drive wheel 3 and the auxiliary wheel 4 each include a rubber coating layer 15 and a wheel axle body 16. The rubber coating layer 15 is located on the outside of the wheel axle body 16, which increases friction and improves shock absorption performance. Both ends of the wheel axle body 16 are inserted into through holes opened on both sides of the baffle frame 7 to bear most of the reaction force during the pushing process.

[0034] See Figures 1 to 9When propelling the train forward, the power output unit 5 is activated by the contact between the outer circumference of the main body of the drive wheel 3 and the groove 12 with the outer circumference of the train wheel. This drives the drive sprocket 8 at the rear end to rotate, and through the transmission action of the chain 9, it simultaneously drives the driven sprocket 10 at the front end to rotate, thus providing power for the rotation of the drive wheel 3. The corresponding train wheel can be pushed according to the direction of the carriage's movement. If the carriage needs to move forward, the train wheel is pushed forward from the rear of the carriage; if the carriage needs to move backward, the train wheel is pushed backward from the front of the carriage. Friction ensures that the train wheel and the drive wheel 3 rotate synchronously, thus propelling the rail vehicle to the designated position. During the propulsion process, the auxiliary wheel 4 needs to rotate clockwise, and the corresponding drive wheel 3 rotates counterclockwise. Once the rail vehicle has been delivered to the designated position, the drive wheel 3 reverses direction, disengaging the propulsion device.

[0035] The above are merely preferred embodiments of the present invention, used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention. Any non-creative modifications, equivalent substitutions, or improvements made by those skilled in the art based on the principles of the present invention should be included within the scope of protection of the present invention.
