Description

Technical Field

[0001] This utility model relates to the field of railway freight car coupler maintenance training device, specifically a railway freight car coupler training bracket. Background Technology

[0002] The connection between railway freight cars usually adopts the James coupler. There is a coupler between the two cars to be connected. The two couplers are connected by a "handshake". Patent document CN219857156U discloses the "handshake" connection method. After the two couplers are connected, the couplers are locked by the locking iron set on the coupler to complete the stable connection of the couplers. When it is necessary to separate the connected couplers, the locking iron structure on the coupler needs to be unlocked by using the coupler lifting rod and moving the two cars away to complete the separation of the couplers. The coupler lifting rod is usually equipped with a front hook at the head and a rear hook at the tail. The front hook is a small hook used to hook the locking iron structure, and the rear hook is perpendicular to the rod body and serves as the operating handle.

[0003] As a fundamental component of railway freight cars, the coupler is one of the most basic and important parts. Its function is to connect locomotives and cars, and cars themselves, to transmit traction force and mitigate longitudinal forces and impacts between vehicles. Its technical condition plays a crucial role in the safe operation of the train. Currently, the quality of regular coupler maintenance and the inspection and maintenance procedures during daily use are fundamental means to ensure its good technical condition. Therefore, improving the coupler inspection and maintenance skills of operators is extremely important.

[0004] Currently, regular inspections and troubleshooting offer limited opportunities for training maintenance personnel, and the types of faults they encounter are also limited. This fails to provide maintenance personnel with more comprehensive learning opportunities, especially for new employees, whose training cycles are long and which is not conducive to the skill enhancement needs of outstanding employees. Therefore, it is essential to design and develop a training support for railway freight car couplers.

[0005] The coupler training stand should facilitate disassembly, maintenance, and assembly. It should be used by new employees to understand the coupler's structure and internal management; meet the daily training and skills enhancement requirements of employees; and facilitate employee skill level assessment and vocational skills competitions. By setting different fault types in the coupler training, employees can master comprehensive maintenance skills. Typically, the length of the hook lifting rod is not uniform. For example, the requirements for the hook lifting rod length differ between the maintenance workshop and the operation workshop during coupler inspection and maintenance operations. The maintenance workshop uses a short hook lifting rod, while the operation workshop uses a long one. Therefore, the coupler training stand should be able to accommodate operations using hook lifting rods of different lengths. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a training bracket for railway freight car couplers, which solves the problem that the current inspection and maintenance operations of railway freight car couplers cannot meet the practical needs of relevant maintenance personnel.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A railway freight car coupler training support includes a vertical frame with two legs. The upper part of the vertical frame has a coupler seat hole, and the lower ends of the legs are connected to base plates. Two vertical frames are horizontally arranged: a front frame and a rear frame. The coupler has a hook head and a hook tail. The hook head has a locking iron, and the hook tail passes through the coupler seat hole of the front frame and into the coupler seat hole of the rear frame. A coupler limiter is provided on the front frame. A hook lifting rod seat is connected to the front frame, and the hook lifting rod seat has a hook lifting rod seat hole. The hook lifting rod has a front hook and a rear hook. The front hook of the hook lifting rod passes through the hook lifting rod seat hole and connects to the locking iron. The extension length of the base plate relative to the vertical frame is longer on the hook head side than on the hook tail side.

[0009] Preferably, the front-end support is connected to a first square tube, a second square tube is slidably nested inside the first square tube, and a hook lifting rod seat is connected to the extended end of the second square tube.

[0010] Preferably, the hook lifting rod seat hole is configured as an elongated hole, the length of the elongated hole is longitudinal, and a wide hole is connected to the upper end of the elongated hole.

[0011] Preferably, the coupler limiting device is a fixing plate and a limiting screw. The fixing plate is fixedly installed above the coupler seat hole of the front upright. The fixing plate is provided with a threaded hole, and the limiting screw is screwed in from the upper end of the threaded hole for engagement.

[0012] This utility model provides a training bracket for railway freight car couplers. It has the following beneficial effects:

[0013] By setting up front and rear uprights, the coupler is stably seated in the coupler seat hole. The movement of the coupler relative to the coupler seat hole can be limited by adjusting the limit screws. By sliding and nesting the second square tube, the extended end of the second square tube is connected to the hook lifting rod seat, which can adjust the distance between the hook lifting rod seat and the coupler. This facilitates the adaptation of the hook lifting rod seat to hook lifting rods of different lengths. The coupler training bracket provides a stable and easy-to-operate coupler training platform, solving the problem that the current inspection and maintenance operations of railway freight car couplers cannot meet the practical needs of relevant maintenance personnel.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" or "linked" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this utility model based on the specific circumstances.

[0020] In the description of the embodiments of this utility model, it should be noted that the terms "upper", "lower", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0021] Please see Figures 1-3This utility model provides a technical solution: a railway freight car coupler training support, comprising a frame 1 with two legs 11, a coupler seat hole 12 on the upper part of the frame 1, and a base plate 2 connected to the lower end of each leg 11; the frame 1 is configured in two horizontal directions, namely a front frame 1a and a rear frame 1b; the coupler 3 is provided with a hook head 31 and a hook tail 32, the hook head 31 is provided with a locking iron, and the hook tail 32... The hook rod passes through the coupler seat hole 12 of the front upright 1a and into the coupler seat hole 12 of the rear upright 1b; the front upright 1a is provided with a coupler limiter 4; the front upright 1a is connected to a hook lifting rod seat 5, the hook lifting rod seat 5 is provided with a hook lifting rod seat hole 51, the hook lifting rod 6 is provided with a front hook and a rear hook, the front hook of the hook lifting rod 6 passes through the hook lifting rod seat hole 51 and is connected to a locking iron, and the extension length of the base plate 2 relative to the upright 1 is longer on the hook head 31 side than on the hook tail 32 side. It should be noted that: The upright frame 1, i.e., the vertical support, consists of two frames: a front upright 1a and a rear upright 1b. These two frames provide a stable platform for the coupler 3, ensuring the key component, the hook head 31 of the coupler 3, is suspended in the air for easy observation, disassembly, assembly, and maintenance. The coupler limiter 4 is used to fix the hook tail 32 of the coupler 3 after it enters the coupler seat hole 12. The extension length of the base plate 2 relative to the upright frame 1 is longer on the hook head 31 side than on the hook tail 32 side, allowing the coupler training support and coupler to be properly positioned. The center of gravity of the 3 is placed on the base plate 2, which enhances the overall stability. The front hook of the hook lifting rod 6 is small and can pass through the hook lifting rod seat hole 51 and connect with the locking iron of the coupler 3. Usually, the specific connection method is as follows: the front hook of the hook lifting rod 6 is connected to the lower locking pin shaft of the coupler 3. The shaft is connected to the coupler locking iron through the lower locking pin assembly (the lower locking pin assembly refers to the hook tongue, hook tongue pin, hook tongue push iron and other components that support the lower locking pin shaft and the locking iron). By pulling or rotating the hook lifting rod 6, the locking state of the locking iron on the coupler 3 can be released, which is to prepare for further observation, disassembly and maintenance of the coupler.

[0022] Please see Figures 1-3 In this embodiment, the front-end support 1a is connected to a first square tube 7, and a second square tube 8 is slidably nested inside the first square tube 7. The extended end of the second square tube 8 is connected to a hook lifting rod seat 5. It should be noted that by pushing and pulling the second square tube 8, the distance between the hook lifting rod seat 5 and the coupler 3 can be changed, making it convenient for the hook lifting rod seat 5 to be adapted to hook lifting rods 6 of different lengths. By pulling or rotating the hook lifting rod 6, the locking state of the locking iron on the coupler 3 can be released, simulating the actual unhooking operation, which is convenient for observation, training and further disassembly of the coupler.

[0023] Please see Figure 1In this embodiment, the hook lifting rod seat hole 51 is set as an elongated hole 511, the length of which is longitudinal, and a wide hole 512 is connected to the upper end of the elongated hole 511. It should be noted that the operation process of the hook lifting rod 6 linking with the locking iron to release the locking iron from the coupler 3 is as follows: by lifting the rear hook of the hook lifting rod 6 (the rear hook is the operating handle), the rod end located on the rear hook is raised to the wide hole 512. Then, by rotating and pulling the hook lifting rod 6, the locking iron is disengaged from the locking position of the coupler 3. Because the rod end located on the rear hook has a certain degree of lateral swing during the above operation, the wide hole 512 provides space for the rod end to swing. At the same time, the setting of the elongated hole 511 and the wide hole 512 also facilitates the front hook of the hook lifting rod 6 to pass through the hook lifting rod seat hole 51 and connect with the locking iron of the coupler 3.

[0024] Please see Figure 1 , Figure 3 In this embodiment, the coupler limiting device 4 is configured as a fixing plate 41 and a limiting screw 42. The fixing plate 41 is fixedly disposed above the coupler seat hole 12 of the front support 1a. The fixing plate 41 is provided with a threaded hole, and the limiting screw 42 is screwed into the threaded hole from the upper end for engagement. It should be noted that by rotating the limiting screw 42 so that the lower end of the limiting screw 42 contacts the coupler 3, the relative movement between the coupler 3 and the coupler seat hole 12 can be restricted.

[0025] The working principle and usage process of this utility model are as follows: The hook tail 32 of the coupler 3 passes through the coupler seat hole 12 of the front upright 1a and into the coupler seat hole 12 of the rear upright 1b, and is fixed by the coupler limit 4; the front hook of the hook lifting rod 6 passes through the hook lifting rod seat hole 51 and connects to the locking iron of the coupler 3; by pushing or pulling the second square tube 8, the second square tube 8 can be retracted or extended relative to the first square tube 7, that is, the distance between the hook lifting rod seat 5 and the coupler 3 is changed, which is convenient for adapting to hook lifting rods 6 of different lengths; by supporting the rear hook of the hook lifting rod 6 (the rear hook is the operating handle), the rod end located on the rear hook is raised to the wide hole 51. At point 2, the locking iron is disengaged from the locking position of the coupler 3 by rotating and pulling the hook lifting rod 6, thus releasing the locking iron from the coupler 3 and preparing for further observation, disassembly, and maintenance of the coupler 3. The coupler training bracket keeps the hook head 31 of the coupler 3 in a stable suspended state, facilitating observation, disassembly, assembly, and maintenance. Similarly, the coupler training bracket is also an assembly platform for the coupler 3 components. By setting different faults on the coupler, the coupler training bracket can achieve comprehensive fault repair training, solving the problem that the current inspection and maintenance operations of railway freight car couplers cannot meet the practical needs of relevant maintenance personnel.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
