[0002] In related technologies, the process of replacing the boom of the coupler buffer device is usually as follows: the car is shunted into the vehicle maintenance depot, the coupler is lifted by a special crane in the vehicle maintenance depot, and then the coupler or boom is replaced. This operation method requires the car to be shunted in and out of the depot, which is cumbersome and also prolongs the locomotive and rolling stock preparation time. Utility Model Content

[0018] A fixed base is provided, wherein the side of the support platform facing away from the lifting mechanism is connected to the fixed base;

[0019] The traveling wheel is rotatably mounted on the fixed base and is used to drive the fixed base to move along the tangential direction of the traveling wheel.

[0020] In one embodiment, the walking wheel has a working state and a non-working state;

[0027] In one embodiment, the coupler buffer device includes a boom; the lifting device also includes a storage rack for storing the boom.

[0028] In this technical solution, a lifting mechanism can be used to drive a support member upwards along a first direction to the height of the coupler buffer device, and the support member supports and fixes the coupler buffer device. Then, the coupler buffer device is removed from the vehicle, and the lifting mechanism drives the support member downwards along the first direction to replace components such as the coupler buffer device's boom.

Detailed Implementation

[0035] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0036] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application 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, and therefore should not be construed as a limitation of this application.

[0037] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0038] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0039] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0040] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0041] The function of the coupler buffer device is to couple locomotives and rolling stock, transmit traction and braking forces, and mitigate longitudinal impacts and vibrations caused by coupling, train deceleration, or stopping. The coupler boom is a crucial component of the coupler buffer device; its function is to bear the weight of the coupler, keeping its swing within a certain range and automatically resetting. Due to long-term load-bearing and displacement, deformation is prone to occur. To ensure train operation safety, the coupler boom must be replaced when deformed.

[0042] In related technologies, the process of replacing the boom of the coupler buffer device is usually as follows: the car is shunted into the vehicle maintenance depot, the coupler is lifted by a special crane in the vehicle maintenance depot, and then the coupler or boom is replaced. This operation method requires the car to be shunted in and out of the depot, which is cumbersome and also prolongs the locomotive and rolling stock preparation time.

[0043] Based on this, this application designs a lifting device to solve the above-mentioned technical problems.

[0044] Figure 1 A schematic diagram of the lifting device 10 in one embodiment of this application is shown.

[0045] Please see Figure 1 One embodiment of this application provides a lifting device 10 for a coupler buffer device (not shown in the figure). The lifting device 10 includes a support member 1, a limiting member 2, a lifting mechanism 3, and a support platform 4.

[0046] The support member 1 supports and secures the coupler buffer device. The lifting mechanism 3 is connected to the support member 1 to drive the support member 1 to move along a first direction F1, which is parallel to the direction from the top to the bottom of the support member 1. The lifting mechanism 3 is mounted on a support platform 4, and a limiting member 2 is mounted on the support platform 4 to limit the movement of the lifting mechanism 3 along a second direction F2 and a third direction F3. The first direction F1, the second direction F2, and the third direction F3 are all perpendicular to each other.

[0047] Thus, when the lifting device 10 is in use, the lifting mechanism 3 can drive the support member 1 to move upward along the first direction F1 to the height where the coupler buffer device is located, and the support member 1 can support and fix the coupler buffer device. Specifically, the support member 1 is used to fix the coupler of the coupler buffer device, and thus can support and fix the coupler buffer device. Then, the coupler buffer device is removed from the vehicle, and the lifting mechanism 3 drives the support member 1 to move downward along the first direction F1 so as to replace the lifting rod and other components of the coupler buffer device. After the replacement is completed, the replaced coupler buffer device is fixed on the support member 1, and then the lifting mechanism 3 drives the support member 1 to move upward along the first direction F1 to the height required by the coupler buffer device, and then the coupler buffer device is installed on the corresponding vehicle. Thus, the lifting device 10 of this application is designed based on the load-bearing and installation requirements of the coupler buffer device, utilizing the disassembly structure and related requirements of the boom. This allows for quick and convenient boom replacement by a single person at the vehicle maintenance site, significantly reducing locomotive and rolling stock maintenance time, increasing locomotive and rolling stock turnaround rate, and ultimately improving railway transportation efficiency. Furthermore, the first limiting member 2 restricts the movement of the lifting mechanism 3 along the second direction F2 and the third direction F3, improving the operational stability of the lifting mechanism 3 and allowing for better utilization of the lifting mechanism 3 to complete the boom replacement operation.

[0048] In some embodiments, the lifting mechanism 3 is a hydraulic jack. Thus, the lifting operation of the coupler buffer device can be better achieved through hydraulic system transmission.

[0049] In this application, after the coupler buffer device is installed on the vehicle, the height of the horizontal center line of the coupler tongue of the coupler buffer device from the ground or rail surface in the empty state is H. The corresponding H for passenger cars is 880mm (+10mm, -5mm), and the corresponding H for freight cars is 880mm (+10mm, -10mm). Therefore, in this application, the stroke of the crane mechanism 3 is set to 420mm-820mm, and the rated lifting capacity of the crane mechanism 3 is set to 5 tons. The height of the support platform 4 along the first direction F1 is set to 400mm-500mm. In this way, the working height requirements of the coupler buffer device can be met, and the support stability of the coupler buffer device can be improved, thereby meeting the operational requirements of locomotive and rolling stock such as changing the boom.

[0050] In some embodiments, please refer to Figure 1 and Figure 2 The limiting member 2 includes a first limiting part 21 and a second limiting part 22 connected together. The first limiting part 21 is located on one side of the crane mechanism 3 along the second direction F2 to restrict the movement of the crane mechanism 3 along the second direction F2. The second limiting part 22 is located on one side of the crane mechanism 3 along the third direction F3 to restrict the movement of the crane mechanism 3 along the third direction F3.

[0051] Thus, the first limiting part 21 restricts the movement of the crane mechanism 3 along the second direction F2, and the second limiting part 22 restricts the movement of the crane mechanism 3 along the third direction F3. In this way, the movement of the crane mechanism 3 can be restricted from multiple directions, thereby improving the stability of the crane mechanism 3 during operation and reducing the probability of the crane mechanism 3 moving during operation, so as to better utilize the crane mechanism 3 to complete the boom replacement operation.

[0052] In some embodiments, such as Figure 3 As shown, the limiting member 2 includes two first limiting parts 21 disposed opposite to each other along the second direction F2, and two second limiting parts 22 disposed opposite to each other along the third direction F3.

[0053] In this way, the crane mechanism 3 can be limited to the two first limiting parts 21 along the second direction F2, and the crane mechanism 3 can be limited to the two second limiting parts 22 along the third direction F3. This can better improve the stability of the crane mechanism 3 during operation, and thus better utilize the crane mechanism 3 to complete the boom replacement operation.

[0054] In some embodiments, the coupler buffer device includes a coupler, and the top of the support member 1 is provided with a slot 11 adapted to the coupler.

[0055] The coupler can be snapped into the slot 11, and the coupler buffer device can be supported and fixed by the support member 1. It is also convenient to remove the coupler and the coupler buffer device from the support member 1. In addition, during the lifting operation of the coupler buffer device, since the coupler is snapped into the slot 11, the coupler is not easy to slip off the support member 1, thereby improving the convenience and stability of the coupler buffer device.

[0056] In some embodiments, the support member 1 is symmetrically arranged with reference to the central axis of the slot 11.

[0057] This improves the stability of the coupler buffer device fixed by the support 1, which in turn facilitates better replacement of the coupler buffer device boom using the lifting device 10.

[0058] In some embodiments, the top of the support platform 4 is provided with a bearing surface 41 for supporting the lifting mechanism 3 and perpendicular to the first direction F1. The lifting mechanism 3 is fixed on the bearing surface 41, and the orthographic projection of the lifting mechanism 3 on the bearing surface 41 is located within the range of the edge of the bearing surface 41.

[0059] The bearing surface 41 is perpendicular to the first direction F1 and is used to support the lifting mechanism 3. The orthographic projection of the lifting mechanism 3 on the bearing surface 41 is located within the range of the edge of the bearing surface 41. In this way, the installation stability of the lifting mechanism 3 can be improved, which in turn helps to improve the stability of the lifting operation of the coupler buffer device.

[0060] In some embodiments, the lifting device 10 further includes a traveling wheel 6 and a fixed seat 8. The side of the support platform 4 away from the lifting mechanism 3 is connected to the fixed seat 8. The traveling wheel 6 is rotatably mounted on the fixed seat 8 and is used to drive the fixed seat 8 to move along the tangential direction of the traveling wheel 6.

[0061] This facilitates the movement of the lifting device 10 to the work site, such as the location of the vehicle whose boom needs to be replaced. This improves the mobility of the lifting device 10, making it easy to move it to the work site for operation or to the storage location for storage.

[0062] In some embodiments, the traveling wheels 6 have an active state and an inactive state. When the traveling wheels 6 are in the active state, along the first direction F1, the bottom of the traveling wheels 6 is lower than the bottom of the fixed base 8. When the traveling wheels 6 are in the inactive state, along the first direction F1, the bottom of the traveling wheels 6 is higher than the bottom of the fixed base 8. All traveling wheels 6 are configured to be operablely switchable between the active state and the inactive state.

[0063] Thus, when it is necessary to move the lifting device 10, such as to the work site, the traveling wheels 6 can be switched to the working state. At this time, along the first direction F1, the bottom of the traveling wheels 6 is lower than the bottom of the fixed seat 8, which facilitates the driving of the fixed seat 8 to move along the tangential direction of the traveling wheels 6, thereby moving the lifting device 10 to the work site. After the movement of the lifting device 10 is completed, the traveling wheels 6 can be switched to the non-working state. At this time, along the first direction F1, the bottom of the traveling wheels 6 is higher than the bottom of the fixed seat 8. The fixed seat 8 is set on the ground where the work site is located, making it difficult for the lifting device 10 to move, which helps to improve the operational stability of the lifting device 10.

[0064] In some embodiments, the lifting device 10 includes a handpiece 5 connected to a fixed base 8 to drive the fixed base 8 to move along the tangential direction of the traveling wheel 6.

[0065] The handheld component 5 can drive the fixed base 8 to move along the tangential direction of the traveling wheel 6, which improves the mobility of the lifting device 10 and makes it easy to move to the work site for operation or to the storage site for storage.

[0066] In some embodiments, the walking wheel 6 is rotatably mounted on the fixed base 8 via the connecting seat 61. Specifically, one end of the connecting seat 61 is connected to the end of the fixed base 8 where the hand-held part 5 is provided, and the walking wheel 6 is rotatably mounted on the other end of the connecting seat 61.

[0067] Thus, the end of the handle 5 away from the fixed base 8 can be pressed down to lift the end of the fixed base 8 away from the handle 5, and the traveling wheel 6 is hinged to the end of the connecting seat 61 away from the fixed base 8. In this way, the traveling wheel 6 will fall down under the action of gravity, so that the traveling wheel 6 is lower than the bottom of the fixed base 8, and the traveling wheel 6 can be switched to the working state; conversely, the end of the handle 5 away from the fixed base 8 can be lifted up and the traveling wheel 6 can be lifted above the fixed base 8, and the traveling wheel 6 can be switched to the non-working state.

[0068] Specifically, the handheld component 5 includes a handheld part 51 and a connecting part 52, which are arranged intersectingly, and the connecting part 52 is connected between the fixed base 8 and the handheld part 51.

[0069] Optionally, the hand-held part 51 and the connecting part 52 are arranged vertically.

[0070] This makes it easy to operate the handpiece 51 to switch the traveling wheels 6 between working and non-working states, and also makes it easy to move the lifting device 10 when the traveling wheels 6 are in working state.

[0071] In some embodiments, the coupler buffer device includes a boom, and the lifting device 10 further includes a storage rack 7 for storing the boom.

[0072] Optionally, the storage rack 7 is provided with a storage slot 71, the opening of which is perpendicular to the first direction F1.

[0073] In this way, the storage rack 7 can be used to store the boom, making it easy to replace the boom that needs to be replaced on the coupler buffer device, thus improving the convenience of boom replacement.

[0074] The lifting device 10 of this application can solve the problem that the replacement of locomotive booms cannot be completed within the locomotive preparation time. After using the lifting device 10, the boom deformation fault can be dealt with during the locomotive preparation time, which greatly shortens the operation time, reduces the workload of the operators, and improves the operation efficiency.

[0075] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0076] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
