Description

Technical Field

[0001] This application relates to the field of track technology, and in particular to a track-taking device for confined spaces at railway frogs. Background Technology

[0002] Rail replacement is a frequent routine operation in railway engineering. Rails not only form the foundation for train movement but also serve as the core channel for track circuits, playing a crucial role in monitoring train occupancy and transmitting operational information. To prevent poor connection between rail circuits, reduce circuit resistance, and ensure stable signal transmission, connecting wires are typically installed between rails. Since both track circuits and connecting wires are electrical engineering equipment, track maintenance personnel must cooperate with electrical engineering specialists to dismantle and reassemble the connecting wires during rail replacement operations.

[0003] During the installation and removal of connecting lines, wire pickers and punches are indispensable specialized tools. These tools can effectively install and remove connecting lines in rail replacement operations on ordinary rails, meeting operational requirements. However, in rail replacement operations at railway frogs, the special shape of the frog structure results in an extremely unique installation position for the connecting lines, creating a restricted working space and greatly limiting the application of traditional tools.

[0004] In existing technologies, the wire take-up head of traditional wire take-up devices is relatively large, making it difficult to effectively stress the plug head of the connecting wire within the confined space of the frog. Reducing the size of the wire take-up head to fit the space would severely compromise its structural strength, leading to easy damage and unusability. Traditional punches, being straight iron rods, are also ill-suited to the confined space of the frog, making it difficult to reach the designated working position. More critically, using existing tools for connecting wire removal and installation at the frog not only makes it difficult to remove the connecting wire smoothly but also easily damages the connecting wire mounting holes on the frog. Damaged mounting holes require re-welding repair by engineering professionals, which not only increases additional work procedures and costs but also significantly prolongs the rail replacement cycle, resulting in extremely low overall work efficiency and severely impacting the normal operation of the railway line.

[0005] Therefore, the existing tools have poor compatibility in the process of disassembling and assembling connecting lines in the confined space of railway frogs, which is not conducive to the smooth progress of rail replacement operations. Utility Model Content

[0006] Therefore, it is necessary to provide a railway frog confined space wire-taking device to address the problem of poor adaptability of existing tools in the process of assembling and disassembling connecting lines in the confined space of railway frogs.

[0007] This utility model provides a railway frog confined space wire-taking device, comprising: a punch body, the punch body including a punching part and a force-receiving part, one end of the punching part being fixedly connected to one end of the force-receiving part, both the punching part and the force-receiving part extending in a straight line, the extension direction of the punching part and the extension direction of the force-receiving part forming an obtuse angle; and a handle connected to one side of the force-receiving part.

[0008] According to one embodiment of the present invention, the stamping part and the force-bearing part are integrally formed.

[0009] According to one embodiment of the present invention, the cross-sectional dimension of the punch body gradually decreases from the end of the force-receiving part away from the stamping part to the end of the stamping part away from the force-receiving part.

[0010] According to one embodiment of the present invention, the handle includes: a grip portion, the grip portion being annular; and a connecting portion, the connecting portion extending in a straight line, one end of the connecting portion being fixedly connected to the grip portion, and the other end being fixedly connected to the force-receiving portion.

[0011] According to one embodiment of the present invention, the gripping part and the connecting part are integrally formed.

[0012] According to one embodiment of the present invention, it further includes: an angle adjustment component, wherein the handle is rotatably connected to the force-receiving part, the angle adjustment component connects the handle and the force-receiving part, and the angle adjustment component is used to adjust the included angle between the handle and the force-receiving part.

[0013] According to one embodiment of the present invention, the angle adjustment assembly includes: an adjustment plate, one end of which is fixedly connected to the force-bearing part, and the adjustment plate is provided with an arc-shaped groove; a positioning bolt, the positioning bolt including a threaded section and a head fixedly connected to the threaded section, the threaded section passing through the arc-shaped groove and being threadedly connected to the handle through a threaded through hole located on the handle, and the head clamping the adjustment plate with the handle.

[0014] According to one embodiment of the present invention, a rotating part is provided at one end of the handle near the force-receiving part. The rotating part is provided with a connecting groove and a first shaft hole communicating with the connecting groove. The force-receiving part passes through the connecting groove and is provided with a second shaft hole axially aligned with the first shaft hole. The force-receiving part and the handle are rotatably connected by a transition shaft passing through the first shaft hole and the second shaft hole.

[0015] According to one embodiment of the present invention, the punch body further includes a positioning part, which is fixedly disposed on the outside of the stamping part.

[0016] According to one embodiment of the present invention, the positioning part gradually tilts from one end connected to the stamping part to one end away from the stamping part toward one end close to the stamping part and away from the force-bearing part. Multiple positioning parts are provided, and the multiple positioning parts are spaced apart along the circumference of the stamping part.

[0017] The aforementioned railway frog confined space wire-taking device, during the assembly and disassembly of connecting wires within the confined space of a railway frog, involves the operator holding the handle in a stable position, ensuring the punching part of the punch body contacts the plug head of the connecting wire. The connection point between the punching part and the force-bearing part contacts the top surface of the track base plate. Pressure is then applied to the force-bearing part through hammering or other methods. At this point, the contact point with the top surface of the track base plate forms a fulcrum, transmitting the force received by the force-bearing part to the punching part. The punching part impacts the plug head of the connecting wire, causing it to insert or disengage from the mounting hole, thus achieving the assembly and disassembly of the connecting wire. Because the extension direction of the punching part and the extension direction of the force-bearing part form an obtuse angle, it can better adapt to the confined space of a railway frog, and the force can be transmitted through cooperation with the track base plate, making operation more convenient.

[0035] Combination Figure 1 and Figure 2 This utility model provides a railway frog confined space wire-taking device, including a punch body 100 and a handle 200. The punch body 100 includes a punching part 110 and a force-receiving part 120. One end of the punching part 110 is fixedly connected to one end of the force-receiving part 120. Both the punching part 110 and the force-receiving part 120 extend in a straight line, and the extension direction of the punching part 110 and the extension direction of the force-receiving part 120 form an obtuse angle. The handle 200 is connected to one side of the force-receiving part 120.

[0036] During operation, the punching part 110 of the punch body 100 can accurately align with the plug head 600 of the connecting line within the confined space of the railway frog. The connecting corner of the punching part 110 and the force-bearing part 120 is tightly fitted with the top surface of the track base plate 500 to form a stable support point. The operator holds the handle 200 and uses it to stably control the position of the punch body 100, ensuring that the punching part 110 and the plug head 600 always maintain accurate contact, without needing to extend their hands or most of the tool into the confined space. When a hammering force or other force is applied to the force-bearing part 120, the punch body 100 uses the contact point with the track base plate 500 as a fulcrum to transmit the force to the punching part 110, enabling the punching part 110 to generate a concentrated and directional impact force on the plug head 600.

[0037] This structure adapts to the confined space of railway frogs. The obtuse angle formed by the stamping part 110 and the force-bearing part 120 avoids the structural obstacles of the frog, solving the problem that traditional tools, due to their large size or upright shape, cannot operate effectively in confined spaces. By using the track base plate 500 as a fulcrum to transmit force, the efficiency of impact force transmission is ensured, and uneven force distribution on the plug head 600 caused by force offset is avoided. This effectively protects the mounting holes for the connecting lines on the frog, eliminating the need for additional welding repairs after damage to the mounting holes. Simultaneously, the handle 200 allows operators to complete the work in a comfortable operating posture, reducing operational difficulty and physical exertion. This makes the disassembly and assembly of the connecting lines smoother and faster, significantly shortening the rail replacement cycle, improving overall operational efficiency, and ensuring the normal operation of the railway line.

[0038] Optionally, the cross-sectional shape of the stamping part 110 and the force-bearing part 120 is circular, elliptical or polygonal, etc.

[0039] According to one embodiment of the present invention, the stamping part 110 and the force-bearing part 120 are integrally formed.

[0040] In some embodiments, the stamping part 110 and the force-bearing part 120 are formed into a complete component through a processing technology such as integral forging or casting. There are no splicing gaps or additional connecting structures between the two, and the materials are consistent. The transition from the force-bearing part 120 to the stamping part 110 is natural and smooth, ensuring the structural integrity of the entire punch body 100.

[0041] The one-piece molding structure gives the punch body 100 higher overall structural strength. When external force is applied to the force-bearing part 120, it can be directly and smoothly transmitted to the stamping part 110 without force loss or structural loosening or breakage at the joint. This effectively avoids tool damage caused by failure of the splicing structure, extends the service life of the device, and ensures the stability and reliability of force transmission during operation, thereby improving the success rate of disassembly and assembly operations.

[0042] According to one embodiment of the present invention, the cross-sectional dimension of the punch body 100 gradually decreases from the end of the force-receiving part 120 away from the stamping part 110 to the end of the stamping part 110 away from the force-receiving part 120.

[0043] In some embodiments, the cross-sectional dimensions of the punch body 100 gradually decrease from the end of the force-receiving portion 120 away from the stamping portion 110 to the end of the stamping portion 110 away from the force-receiving portion 120. The force-receiving portion 120 maintains a relatively large cross-section to withstand external forces such as hammering, while the stamping portion 110 gradually reduces its cross-sectional dimensions along the extension direction, so that the end of the stamping portion 110 can form a concentrated working end and facilitate the stamping of the plug head 600.

[0044] The gradual design of the cross-sectional dimensions ensures that the force-bearing part 120 has sufficient structural strength to resist external impacts, while also allowing the stamping part 110 to accurately extend into the narrow working space and contact the plug head 600, thus achieving concentrated force transmission. This avoids the problem of insufficient strength caused by the stamping part 110 being too large to fit the limited space or the force-bearing part 120 being too small. At the same time, it reduces the interference of tools in the space, making the placement and adjustment of the punch body 100 more flexible and convenient, and improving the operability of the operation.

[0045] According to one embodiment of the present invention, the handle 200 includes a gripping portion 210 and a connecting portion 220. The gripping portion 210 is annular, and the connecting portion 220 extends in a straight line. One end of the connecting portion 220 is fixedly connected to the gripping portion 210, and the other end is fixedly connected to the force-receiving portion 120.

[0046] The ring-shaped grip 210 provides a stable grip point for the operator, increases the contact area between the hand and the grip 210, prevents hand slippage during operation, and improves operational safety. The straight-line extending connecting part 220 ensures smooth force transmission between the handle 200 and the force-bearing part 120. At the same time, the reasonable structural layout allows the operator to complete the operation without having to put their hands close to the confined space, reducing the difficulty of operation and physical exertion, and improving the comfort and efficiency of the operation.

[0047] According to one embodiment of the present invention, the gripping part 210 and the connecting part 220 are integrally formed.

[0048] In some embodiments, the grip 210 and the connecting part 220 are made of the same raw material and are processed in one piece, such as by bending or shaping a metal rod, so that the grip 210 and the connecting part 220 naturally transition into a whole, without any additional connecting parts 220 or splicing gaps between them, resulting in a compact and complete structure.

[0049] For example, the grip portion 210 and the connecting portion 220 are formed from the same metal rod. By bending one end of the metal rod, the end of the metal rod contacts the position near the middle of the metal rod to form an elongated grip portion 210, and the part of the metal rod outside the grip portion 210 forms the connecting portion 220.

[0050] The one-piece molded handle 200 structure makes the connection between the grip 210 and the connecting part 220 stronger, effectively withstanding the force transmitted during operation, avoiding operational errors or tool damage caused by loose connection, while simplifying the processing technology of the handle 200, reducing assembly steps, lowering production and manufacturing costs, and making the overall structure simpler, making it easier for operators to carry and use, and improving the practicality of the tool.

[0051] Combination Figure 3According to one embodiment of the present invention, the railway frog confined space wire taking device further includes an angle adjustment component 300, the handle 200 is rotatably connected to the force receiving part 120, the angle adjustment component 300 connects the handle 200 and the force receiving part 120, and the angle adjustment component 300 is used to adjust the included angle between the handle 200 and the force receiving part 120.

[0052] In some embodiments, the handle 200 and the force-receiving part 120 are rotatably connected, and the angle adjustment component 300 is installed between them to fix the relative position after rotation. The operator can rotate the handle 200 to adjust the angle between it and the force-receiving part 120 according to the actual structure of the restricted space of the turnout and the working angle requirements. After adjusting to a suitable posture, the angle is locked by the angle adjustment component 300 to prevent the handle 200 from rotating arbitrarily during operation.

[0053] The adjustable angle design allows the device to adapt to the limited space of turnouts of different sizes and structures. No matter how the angle of the working position changes, the operator can find a comfortable and effective operating posture by adjusting the handle by 200 degrees. This avoids the problem of not being able to apply force or applying force unevenly due to space angle limitations, further improving the adaptability and flexibility of the device, making the operation process smoother, and improving its applicability in different working scenarios.

[0054] According to one embodiment of the present invention, the angle adjustment assembly 300 includes an adjustment plate 310 and a positioning bolt 320. One end of the adjustment plate 310 is fixedly connected to the force-bearing part 120, and the adjustment plate 310 is provided with an arc-shaped groove 311; the positioning bolt 320 includes a threaded section and a head fixedly connected to the threaded section, the threaded section passes through the arc-shaped groove 311 and is threadedly connected to the handle 200 through a threaded through hole located in the handle 200, and the head clamps the adjustment plate 310 with the handle 200.

[0055] In some embodiments, one end of the adjusting plate 310 is fixed to the side of the force-bearing part 120. The arc-shaped groove 311 on the adjusting plate 310 provides a moving path for the positioning bolt 320. After the threaded section of the positioning bolt 320 passes through the arc-shaped groove 311, it engages with the threaded through hole on the handle 200 and is tightened, so that the head of the positioning bolt 320 and the side of the handle 200 together clamp the adjusting plate 310. When the angle needs to be adjusted, the positioning bolt 320 is loosened, and the handle 200 can drive the positioning bolt 320 to move along the arc-shaped groove 311 to achieve the angle adjustment. After the adjustment is in place, the positioning bolt 320 is tightened again to complete the locking.

[0056] This angle adjustment component 300 has a simple and reliable structure. The arc groove 311 can accurately limit the rotation trajectory of the handle 200, ensuring the accuracy of angle adjustment. The clamping and fixing method of the positioning bolt 320 can provide sufficient locking force to prevent angle deviation caused by vibration during operation. At the same time, it is easy to operate. Operators can complete the angle adjustment and locking without the need for additional tools, which improves the convenience and efficiency of operation and ensures the stability of operation at different angles.

[0057] According to one embodiment of the present invention, a rotating part 230 is provided at one end of the handle 200 near the force-receiving part 120. The rotating part 230 is provided with a connecting groove and a first shaft hole communicating with the connecting groove. The force-receiving part 120 passes through the connecting groove and is provided with a second shaft hole axially aligned with the first shaft hole. The force-receiving part 120 and the handle 200 are rotatably connected by a transition shaft passing through the first shaft hole and the second shaft hole.

[0058] The connecting groove on the rotating part 230 can wrap around a part of the force-receiving part 120, so that the force-receiving part 120 is embedded in the connecting groove. After the first shaft hole and the second shaft hole are axially aligned, the adapter shaft passes through the two shaft holes to connect the rotating part 230 and the force-receiving part 120. The fit between the adapter shaft and the shaft hole ensures smooth rotation, while restricting the relative movement of the two in other directions. When the operator turns the handle 200, the rotating part 230 rotates around the adapter shaft relative to the force-receiving part 120.

[0059] This rotating connection structure makes the rotation of the handle 200 more flexible and smooth. The connecting groove increases the contact area between the rotating part 230 and the force-bearing part 120, improving the stability and structural strength of the connection and preventing shaking or jamming during rotation. The adapter shaft ensures the fixation of the rotation center, making the angle adjustment more precise and controllable, further improving the reliability of angle adjustment and ensuring the stability of force transmission during operation.

[0060] According to another embodiment of this utility model, the handle 200 is welded to the force-bearing part 120. Welding ensures a stable connection between the handle 200 and the force-bearing part 120, preventing damage during prolonged use.

[0061] Combination Figure 4 According to one embodiment of the present invention, the punch body 100 further includes a positioning part 400, which is fixedly disposed on the outside of the stamping part 110.

[0062] In some embodiments, the positioning part 400 is fixed to the outer surface of the stamping part 110 and is located close to the end of the stamping part 110. When the stamping part 110 contacts the plug head 600, the positioning part 400 forms a gap with the frog surface. When the stamping part 110 enters the mounting hole and pushes out the plug head 600, the positioning part 400 contacts the frog surface to limit the position of the stamping part 110, so as to prevent the stamping part 110 from being excessively inserted into the mounting hole during operation and causing damage to the mounting hole, and to facilitate the removal of the stamping part 110 from the mounting hole.

[0063] According to one embodiment of the present invention, the positioning part 400 gradually tilts from the end connected to the stamping part 110 to the end away from the stamping part 110 toward the end close to the stamping part 110 away from the force-bearing part 120. Multiple positioning parts 400 are provided, and the multiple positioning parts 400 are arranged at intervals along the circumference of the stamping part 110.

[0064] When the stamping part 110 is inserted into the mounting hole and ejects the plug head 600, multiple inclined positioning parts 400 can contact the surface of the fork located outside the mounting hole from different directions, and work together to position it. On the one hand, this can prevent the stamping part 110 from tilting or shaking and damaging the mounting hole, and on the other hand, it can prevent a single positioning part 400 from being damaged due to excessive force.

[0065] The positioning part 400 can adopt a rod-shaped or plate-shaped structure. Optionally, the positioning part 400 is an elastic element that can produce a certain elastic bending deformation, which can prevent the positioning part 400 from rigidly contacting the frog surface and damaging the positioning part 400 or the frog.

[0066] In some other embodiments, the positioning part 400 is an annular plate arranged around the outside of the stamping part 110, which can also play a positioning role.

[0067] 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.

[0068] 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.
