Railway rail turning device

Abstract

The application relates to a rail turning device for railway rail turning. The rail turning device for railway rail turning comprises a rail turning mechanism and a prying mechanism. The rail turning mechanism comprises a clamping part and a handle part connected with each other. The clamping part is provided with a clamping opening capable of clamping on a rail to be turned. Rotating the handle part in the direction of the rail to be turned can drive the clamping part to turn the rail. The prying mechanism is detachably connected to the handle part and can drive the handle part to rotate synchronously. By arranging the clamping part, the clamping opening on the clamping part is clamped on the rail to be turned, and the handle part is driven to rotate synchronously by the prying mechanism, so that the rail is turned. Since the prying mechanism is detachably connected to the handle part, the prying mechanism and the rail turning mechanism can be separated in a non-working state, so that the space occupation of the rail turning device is reduced, and the storage and transportation are more convenient.

Description

Technical Field

[0001] This application relates to the field of railway maintenance technology, and in particular to a rail turner for turning railway rails. Background Technology

[0002] With the rapid development of the railway industry, heavy-haul railways are experiencing a year-on-year increase in heavy-haul transport volume. Affected by this increased volume, rail damage is also increasing annually. Since severely damaged rails require immediate replacement, a large number of spare rails need to be prepared on-site for timely replacement. Most of these spare rails are stored under the shoulder, and for aesthetic reasons and to avoid obstructing the movement of daily inspection personnel, they are usually stored near the barbed wire fence. During construction, it is generally necessary to turn the rails over, which requires the use of rail turners.

[0003] Traditional track tilters are quite large, which makes them inconvenient to store and transport. Utility Model Content

[0004] Therefore, it is necessary to provide a rail-turning device for railway rails that can separate the rail-turning mechanism and the prying mechanism when not in operation, making it convenient for storage and transportation.

[0005] This application provides a rail-turning device for railway rails, which includes:

[0006] A rail-turning mechanism, comprising a locking part and a handle part connected to each other, wherein the locking part is provided with a locking port, the locking port being able to lock onto the rail to be turned, and rotating the handle part along the direction to be turned of the rail can drive the locking part to turn the rail.

[0007] The prying mechanism is detachably connected to the handle and can drive the handle to rotate synchronously.

[0008] In one embodiment, the handle portion includes:

[0009] An extension rod, the first end of which is connected to the side of the locking part away from the locking opening, and the second end of which extends away from the locking opening;

[0010] A connecting rod is connected to the second end of the extension rod and extends in a direction perpendicular to the direction to be flipped; the prying mechanism is sleeved on the connecting rod along the extension direction of the connecting rod.

[0011] In one embodiment, a limiting element is provided on the connecting rod and / or the prying mechanism, the limiting element being used to restrict the rotation of the prying mechanism relative to the connecting rod, so that the connecting rod and the prying mechanism rotate synchronously.

[0012] In one embodiment, at least two prying mechanisms are provided, and the at least two prying mechanisms are spaced apart along the extension direction of the connecting rod.

[0013] In one embodiment, at least two limiting members are fixedly provided on the connecting rod, and each prying mechanism can be fitted onto one of the limiting members.

[0014] In one embodiment, the limiting member is provided at least at both ends of the connecting rod in the extension direction.

[0015] In one embodiment, the limiting member is disposed on the connecting rod and is configured as a nut structure; the prying mechanism is provided with a corresponding matching slot, and the nut structure can be inserted into the slot.

[0016] In one embodiment, the locking part is provided with at least two locking ports, and the diameters of the at least two locking ports are different.

[0017] In one embodiment, the locking part is configured as a triangular structure with three locking surfaces connected end to end in sequence; wherein the handle part is connected to the connection of two of the locking surfaces, and at least two of the locking surfaces are provided with locking openings.

[0018] In one embodiment, a hook is provided on one side of the locking port, which can lock onto one surface of the rail; the other side of the locking port can abut against the opposite surface of the rail to form a lever fulcrum.

[0019] The aforementioned rail-turning device for railway rails utilizes a locking mechanism that engages with the rail to be turned. A prying mechanism drives the handle to rotate synchronously, thus turning the rail. Because the prying mechanism is detachably connected to the handle, it can be separated from the rail-turning mechanism when not in operation, reducing the space occupied by the rail-turning device and facilitating storage and transportation.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] See Figure 1 , Figure 1 This illustration shows a schematic diagram of the working state of a rail flipper provided in one embodiment of this application. This application provides a rail flipper for railway rail flipping, which can be used to flip rails prepared on a railway line to quickly adjust the rails to the working angle. Specifically, the rail flipper includes a rail flipping mechanism 1 and a prying mechanism 2. The rail flipping mechanism 1 includes a locking part 11 and a handle part 12 connected together. The locking part 11 is provided with a locking opening 111, which can lock onto the rail 100 to be flipped. Rotating the handle part 12 along the direction to be flipped of the rail 100 can drive the locking part 11 to flip the rail 100. The prying mechanism 2 is detachably connected to the handle part 12 and can drive the handle part 12 to rotate synchronously. Specifically, the rail 100 is generally an I-beam rail, and the direction to be flipped of the rail 100 is as follows... Figure 1 The direction indicated by the middle arrow F.

[0035] The rail flipper provided in this embodiment of the application uses a locking part 11 to lock onto the rail 100 to be flipped via a locking port 111. The lever mechanism 2 drives the handle part 12 to rotate synchronously, thereby achieving the purpose of flipping the rail 100. Since the lever mechanism 2 is detachably connected to the handle part 12, it can be separated from the rail flipping mechanism 1 when not in operation, reducing the space occupied by the rail flipper and making it more convenient for storage and transportation.

[0036] Please see Figure 2 and Figure 3 , Figure 2 A schematic diagram of the disassembly structure of the track tilter provided in one embodiment of this application is shown; Figure 3 A schematic diagram of the tilting mechanism 1 provided in one embodiment of this application is shown.

[0037] In some embodiments, the handle portion 12 includes an extension rod 121 and a connecting rod 122. The first end 1211 of the extension rod 121 is connected to the side of the locking portion 11 facing away from the locking opening 111, and the second end 1212 of the extension rod 121 extends away from the locking opening 111. The connecting rod 122 is connected to the second end 1212 of the extension rod 121 and extends perpendicular to the direction to be flipped. The prying mechanism 2 is sleeved onto the connecting rod 122 along its extension direction. By providing the extension rod 121 to connect the connecting rod 122 and the locking portion 11, the installation of the connecting rod 122 is more convenient. By extending the connecting rod 122 perpendicular to the direction to be flipped, both ends of the connecting rod 122 protrude beyond the extension rod 121, thereby providing a sleeve space for the prying mechanism 2.

[0038] Optionally, the tilting mechanism 1 is designed as a single integrated structure to achieve better structural strength and eliminate assembly steps, making it easy to operate.

[0039] Of course, for ease of storage and transportation, the locking part 11 and the handle part 12 can also be made into a detachable structure, for example, by using a bolt connection.

[0040] In some embodiments, a limiting member 1221 is provided on the connecting rod 122 and / or the prying mechanism 2. The limiting member 1221 is used to restrict the rotation of the prying mechanism 2 relative to the connecting rod 122 so that the connecting rod 122 and the prying mechanism 2 rotate synchronously.

[0041] Optionally, the limiting member 1221 is disposed on the connecting rod 122 and is constructed as a nut structure; the prying mechanism 2 is provided with a corresponding matching slot 221, and the nut structure can be inserted into the slot 221. Through the insertion and engagement of the nut structure and the slot 221, the prying mechanism 2 and the connecting rod 122 are detachably connected, while the rotation of the prying mechanism 2 relative to the connecting rod 122 is restricted.

[0042] In other embodiments, the limiting member 1221 may also be configured as a limiting block, which protrudes from the outer peripheral surface of the connecting rod 122. A connecting groove is provided on the prying mechanism 2, which is used to fit onto the connecting rod 122. A groove is further provided on the groove wall of the connecting groove so that the limiting block can be inserted into the groove, thereby restricting the rotation of the prying mechanism 2 relative to the connecting rod 122.

[0043] In some embodiments, at least two prying mechanisms 2 are provided. When the rail 100 is heavy, multiple operators can operate one prying mechanism 2 respectively and work together to flip the rail 100.

[0044] Specifically, at least two prying mechanisms 2 are spaced apart along the extension direction of the connecting rod 122, so that at least two prying mechanisms 2 can apply a uniform and consistent prying force to the connecting rod 122, which is more conducive to realizing the flipping operation of the rail 100.

[0045] Correspondingly, at least two limiting members 1221 are fixedly provided on the connecting rod 122, and each prying mechanism 2 can be fitted onto a limiting member 1221, so that each prying mechanism 2 can move synchronously with the connecting rod 122.

[0046] Optionally, limiting members 1221 are provided at least at both ends of the connecting rod 122 in the extending direction. That is, the prying mechanism 2 can be sleeved on both ends of the connecting rod 122. On the one hand, the prying mechanism 2 can be quickly sleeved on the limiting members 1221 at the ends; on the other hand, it is also beneficial to position the two prying mechanisms 2 so that the two prying mechanisms 2 are symmetrically arranged relative to the extension rod 121, thereby enabling the application of a uniform prying force to the rail-turning mechanism 1.

[0047] Combination Figure 2 and Figure 4 , Figure 4 A schematic diagram of the prying mechanism 2 provided in one embodiment of this application is shown. In some embodiments, the prying mechanism 2 includes a pry bar 21 and a pry head 22. The pry head 22 is disposed at one end of the pry bar 21, and the aforementioned slot 221 is provided on the pry head 22. The other end of the pry bar 21 is used for gripping by the operator. By providing the pry head 22, the area of ​​the slot 221 is increased, and the slot 221 has a larger wall thickness, thereby improving the resistance to twisting.

[0048] Please see Figure 2 and Figure 3 In some embodiments, the locking part 11 is provided with at least two locking openings 111, and the diameters of the at least two locking openings 111 are different. By providing multiple locking openings 111, the locking part 11 can be locked at different parts of the rail 100, so as to realize the flipping of the rail 100 in various states.

[0049] Specifically, the locking part 11 is configured as a triangular structure with three locking surfaces connected end to end in sequence; wherein the handle part 12 is connected to the connection point of two of the locking surfaces, and locking openings 111 are provided on at least two of the locking surfaces.

[0050] In this embodiment, locking openings 111 are provided on two locking surfaces. In other embodiments, depending on the flipping requirements, locking openings 111 may be provided on all three locking surfaces to improve the applicability of the track flipper.

[0051] Combination Figure 1 and Figure 3 As shown, in some embodiments, a hook 112 is provided on one side of the locking port 111, which can lock onto one surface of the rail 100. The other side of the locking port 111 can abut against the opposite surface of the rail 100 to form a lever fulcrum.

[0052] by Figure 1 Taking the rail 100 shown as an example, when flipping the rail 100, the hook 112 is locked onto the bottom side of the upper crossbeam of the rail 100, and the other side of the locking port 111 is pressed against the top side of the upper crossbeam of the rail 100. By rotating the pry bar 21 counterclockwise, the rail 100 can be flipped counterclockwise.

[0053] Because the upper crossbeam of rail 100 is relatively thick, a larger locking opening 111 can be used to lock rail 100 when it is being jammed and flipped. The lower crossbeam of rail 100 is relatively thin, so a smaller locking opening 111 can be used to lock rail 100.

[0054] 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.

[0055] 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.
