Description

Technical Field

[0001] This utility model relates to the technical field of rail locomotive parking equipment, and specifically discloses an automatic parking device for rail locomotives and a rail locomotive. Background Technology

[0002] Rail locomotives are special-purpose powered vehicles that rely on rails to run. They are mainly used to haul railway trains, urban rail transit vehicles, or carry out transportation operations within industrial and mining enterprises. Before a rail locomotive stops, a parking device is usually required to park it.

[0003] Chinese patent CN222346997U discloses an automatic parking device for a rail locomotive, comprising: a brake seat disposed on the outside of a wheel, an installation compartment provided on the side of the brake seat near the wheel, a retractable brake shoe provided in the installation compartment, and a drive block movably mounted on one side of the brake seat. One end of the drive block can be inserted between the brake seat and the brake shoe. The drive block is used to drive the brake shoe to extend out of or retract from the brake seat. The drive block has a rectangular columnar structure, and the bottom of the drive block near the brake shoe has an inclined surface, one end of which extends between the brake seat and the brake shoe. This utility model adds a movable drive block... The automatic parking device for rail locomotives, which increases the distance between the brake shoes and the brake seat by moving the drive block, can limit the brake shoes on the brake seat and prevent them from retracting into the brake seat, thus improving the stability of the brake shoes during parking. However, during the use of the above device, the components that require electricity, such as the motor, are highly dependent on the external power supply and do not have the corresponding endurance. When the locomotive's own power supply system fails, it cannot supply power to the motor, thereby affecting the normal use of the motor and the above device, which to some extent increases the limitations of the above device. Therefore, in order to solve the above problems, this utility model proposes an automatic parking device for rail locomotives and a rail locomotive. Utility Model Content

[0004] The present invention aims to provide an automatic parking device for rail locomotives and a rail locomotive, which can reduce the dependence of electrically powered components such as electric telescopic rods on external power sources, and ensure that the electric telescopic rods can still extend and retract smoothly when the locomotive's own power supply fails, thereby driving the L-shaped push plate and its connecting parts to move, and ensuring the effectiveness of the device.

[0005] This utility model is achieved through the following technical solution:

[0006] An automatic parking device for a railcar and a railcar include a wheel body. A parking mechanism is provided on one side of the wheel body, and a protective mechanism is provided on the outer side of the parking mechanism. The parking mechanism includes an arc-shaped plate, with anti-slip pads and mounting plates respectively provided on both sides of the arc-shaped plate. An L-shaped push plate is provided on one side of the mounting plate, and two mounting shafts are symmetrically connected to the side of the L-shaped push plate near the mounting plate. An electric telescopic rod is connected to the middle of the side of the L-shaped push plate away from the mounting plate, and a support plate is connected to the outer side of the electric telescopic rod. Guide rods are provided on both sides of the electric telescopic rod. The protective mechanism includes a housing, with a battery compartment provided on the inner side of the housing away from the L-shaped push plate. A battery is provided inside the battery compartment, and a wiring hole is provided on the side of the battery compartment near the electric telescopic rod. A reserved hole corresponding to the position of the battery compartment is provided on one side of the housing.

[0007] As a further feature of the above solution, a groove is provided on one side of the arc-shaped plate, which can fit against the protrusion on one side of the wheel body to avoid conflict between the arc-shaped plate and the protrusion on one side of the wheel body, thus ensuring the braking effect of the parking mechanism on the wheel body. The mounting plate has two symmetrical mounting holes inside, and two mounting shafts pass through the two mounting holes respectively. Nuts are threaded on the outside of the mounting shafts to facilitate the disassembly and assembly of the mounting plate, so as to replace the mounting plate and the arc-shaped plate and the worn anti-slip pad, thus ensuring the anti-slip effect of the anti-slip pad.

[0008] As a further feature of the above solution, the ends of both guide rods near the L-shaped push plate are connected to the L-shaped push plate, facilitating the assembly and disassembly of the guide rods. The guide rods pass through the interior of the support plate and are slidably connected to the support plate, providing stable support for the L-shaped push plate and its connecting components, reducing the downward force exerted by the above components on the telescopic end of the electric telescopic rod, and extending the service life of the electric telescopic rod. Springs are fitted on the outer sides of both guide rods to limit the position of the L-shaped push plate and its connecting components.

[0009] As a further feature of the above solution, both ends of the spring are connected to connecting rings, and the guide rod passes through the interior of the connecting ring and is slidably connected to the connecting ring, which can avoid positional conflict between the guide rod and the connecting ring. The two ends of the connecting ring are detachably connected to the L-shaped push plate and the support plate, respectively, which facilitates the installation and maintenance of the spring.

[0010] As a further feature of the above solution, a through hole is provided at the end of the outer casing away from the battery compartment to avoid positional conflicts between the outer casing and components such as the L-shaped push plate and the arc plate in the parking mechanism. The two sides of the support plate are detachably connected to the two sides of the outer casing, facilitating the installation and maintenance of the support plate and its connecting components. A sealing plate is provided on the side of the reserved hole away from the battery, and both ends of the sealing plate are detachably connected to the outer casing, facilitating the installation and removal of the sealing plate and providing convenience for users to connect the battery to an external power source. A label plate is provided on one side of the sealing plate to facilitate the labeling of information such as the battery model and charging voltage.

[0011] As a further feature of the above solution, the top and bottom ends of the outer shell are detachably connected to a top plate and a bottom plate, respectively, to facilitate the disassembly and assembly of the above components and to maintain the relevant components in the outer shell and the parking mechanism inside.

[0012] As a further feature of the above solution, the electric telescopic pole is connected to the battery via a power cord, which facilitates the battery to power the electric telescopic pole and reduces the electric telescopic pole's dependence on an external power source. The electric telescopic pole is also connected to the terminal device via an electrical signal, which allows the user to control the extension and retraction of the electric telescopic pole to move the corresponding components.

[0013] The present invention has the following beneficial effects during use:

[0014] The combination of mounting plate, mounting shaft, and nut in the parking mechanism allows users to easily disassemble and assemble the mounting plate to replace the mounting plate and its connected arc plate and worn anti-slip pad, ensuring the friction effect between the anti-slip pad and the wheel body.

[0015] The use of electric telescopic booms allows for the extension of the boom before parking, pushing components such as the L-shaped push plate and the arc plate towards the wheel body. This causes the anti-slip mat to contact the wheel body and generate friction, preventing the wheel body from rolling. The combination of the battery compartment, battery, and sealing plate reduces the dependence of the electric telescopic boom and the device on an external power source, ensuring that the device can still function stably when the locomotive's power supply fails.

[0027] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The following will refer to the appendix... Figures 1-9 This application will be described in detail with reference to the embodiments.

[0029] This embodiment discloses an automatic parking device for a rail locomotive and a rail locomotive, including a wheel body 1. A parking mechanism 2 is provided on one side of the wheel body 1, and a protective mechanism 3 is provided on the outer side of the parking mechanism 2. The parking mechanism 2 includes an arc-shaped plate 21, and anti-slip pads 212 and mounting plates 22 are respectively provided on both sides of the arc-shaped plate 21. An L-shaped push plate 23 is provided on one side of the mounting plate 22. Two mounting shafts 24 are symmetrically connected to the side of the L-shaped push plate 23 closest to the mounting plate 22, and the side of the L-shaped push plate 23 furthest from the mounting plate 22... An electric telescopic rod 25 is connected in the middle, and a support plate 26 is connected to the outside of the electric telescopic rod 25. Guide rods 27 are provided on both sides of the electric telescopic rod 25. The protective mechanism 3 includes a housing 31. A battery compartment 312 is provided on the inner side of the housing 31 away from the L-shaped push plate 23. A battery 32 is provided inside the battery compartment 312. A wiring hole 313 is provided on the side of the battery compartment 312 near the electric telescopic rod 25. A reserved hole 314 corresponding to the position of the battery compartment 312 is provided on one side of the housing 31.

[0030] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 7 As shown, a groove 211 is provided on one side of the arc plate 21, which can fit against the protrusion on one side of the wheel body 1 to avoid conflict between the arc plate 21 and the protrusion on one side of the wheel body 1, thus ensuring the braking effect of the parking mechanism 2 on the wheel body 1. Two mounting holes 221 are symmetrically arranged inside the mounting plate 22, and two mounting shafts 24 pass through the two mounting holes 221 respectively. Nuts 241 are threaded on the outside of the mounting shafts 24 to facilitate the disassembly and assembly of the mounting plate 22, so as to replace the mounting plate 22 and the arc plate 21 connected thereto and the worn anti-slip pad 212, thus ensuring the anti-slip effect of the anti-slip pad 212.

[0031] like Figure 2 , Figure 3 and Figure 7 As shown, the ends of the two guide rods 27 near the L-shaped push plate 23 are connected to the L-shaped push plate 23, facilitating the disassembly and assembly of the guide rods 27. The guide rods 27 pass through the interior of the support plate 26 and are slidably connected to the support plate 26, providing stable support for the L-shaped push plate 23 and its connecting components, reducing the downward force exerted by the above components on the telescopic end of the electric telescopic rod 25, and extending the service life of the electric telescopic rod 25. Springs 28 are sleeved on the outer sides of the two guide rods 27, which can limit the position of the L-shaped push plate and its connecting components.

[0032] like Figure 2 , Figure 3 and Figure 7As shown, both ends of the spring 28 are connected to connecting rings 281. The guide rod 27 passes through the interior of the connecting ring 281 and is slidably connected to the connecting ring 281, which can avoid positional conflict between the guide rod 27 and the connecting ring 281. Both ends of the connecting ring 281 are detachably connected to the L-shaped push plate 23 and the support plate 26, respectively, which facilitates the installation and maintenance of the spring 28.

[0033] like Figure 1 , Figure 2 , Figure 5 and Figure 9 As shown, the outer casing 31 has a through hole 311 at the end away from the battery compartment 312, which can prevent the outer casing 31 from interfering with the position of components such as the L-shaped push plate 23 and the arc plate 21 in the parking mechanism 2. The two sides of the support plate 26 are detachably connected to the two sides of the outer casing 31, which facilitates the installation and maintenance of the support plate 26 and its connecting components. The reserved hole 314 has a sealing plate 33 on the side away from the battery 32. Both ends of the sealing plate 33 are detachably connected to the outer casing 31, which facilitates the installation and removal of the sealing plate 33 and provides convenience for users to connect the battery 32 to an external power source. A label plate 34 is provided on one side of the sealing plate 33 to facilitate the labeling of information such as the battery model and charging voltage.

[0034] like Figure 1 and Figure 8 As shown, the top plate 35 and the bottom plate 36 are detachably connected to the upper and lower ends of the outer casing 31, respectively, which facilitates the disassembly and assembly of the above-mentioned components and the maintenance of the relevant components in the outer casing 31 and the parking mechanism 2 inside it.

[0035] like Figure 2 and Figure 3 As shown, the electric telescopic pole 25 is connected to the battery 32 via a power cord, which facilitates the battery 32 to supply power to the electric telescopic pole 25 and reduces the electric telescopic pole 25's dependence on an external power source. The electric telescopic pole 25 is connected to the terminal device via an electrical signal, which facilitates the user to control the extension and retraction of the electric telescopic pole 25 to drive the movement of corresponding components.

[0036] The automatic parking device and railcar disclosed in this embodiment are as follows: Before use, the top plate 35 and the sealing plate 33 are removed, the charging port of the battery 32 is aligned with the reserved hole 314, and the electric telescopic rod 25 is connected to the battery 32 using a power cable. The connection between the top plate 35 and the outer casing 31 is then restored. Depending on the specific model of the railcar to which the device is applied, a corresponding connecting component (not shown) is added above the top plate 35 so that the device can be installed on one side of a wheel body 1 of the railcar. After installation, the charging port of the battery 32 is connected to an external power source via a charging cable to charge the battery 32. Once fully charged, the connection between the battery 32 and the external power source is disconnected, the charging cable is unplugged, and the connection between the sealing plate 33 and the outer casing 31 is restored. The terminal device used to control the electric telescopic rod 25, such as a remote control, is placed in the hand of the railcar driver or in the railcar cab. For use, when parking is required, the terminal device is used to control the extension of the electric telescopic rod 25, stretching the two springs 28, causing the guide rod 27 to slide at both ends inside the support plate 26, pushing the L-shaped push plate 23, mounting plate 22, arc plate 21 and anti-slip pad 212 toward the pulley. After the anti-slip pad 212 and the slot 211 respectively press against the wheel body 1 and the convex plate on one side of the wheel body 1, the terminal device is used to control the electric telescopic rod 25 to stop extending. The electric telescopic rod 25, through the pressure applied to the wheel body 1 by the slot 211 and the anti-slip pad 212, and the friction between the anti-slip pad 212 and the wheel body 1, can effectively prevent the wheel body 1 from rolling, thereby achieving the purpose of parking. When parking, the terminal device is used again to control the electric telescopic rod 25 to retract, causing the slot 211 and the anti-slip pad 212 to separate from the wheel body 1, releasing the fixation on the wheel body 1.

[0037] The automatic parking device for a rail locomotive disclosed in this utility model, as well as the wheel body 1, arc plate 21, anti-slip pad 212, mounting plate 22, L-shaped push plate 23, mounting shaft 24, nut 241, electric telescopic rod 25, guide rod 27, spring 28, connecting ring 281, outer shell 31, battery 32, sealing plate 33, marking plate 34, top plate 35, and bottom plate 36 in the rail locomotive, are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
