[0025] The application will be described in more detail below based on the embodiments and with reference to the drawings.

[0026] As Figures 1-4 shown in the drawings, the application provides a kind of auxiliary device for frog replacement, including pull rope and slide rail 10, slide rail 10 has the guide surface 20 of inclination along the same direction, slide rail 10 can be overlapped on rail and form limit structure with it, one end of pull rope can be connected with frog located at one side of rail, the other end is connected with power component, power component can drive pull rope to move, to make frog can be moved along guide surface 20 from one side of rail to the other side.

[0027] Specifically, the frog needing replacement is located in the middle of the rail on both sides of track, in the process of replacement, the frog needing replacement needs to be moved to the ballast shoulder outside the rail on both sides, which is the process of derailing; and the frog after being repaired or the new frog is moved from outside the rail to between the rail on both sides, which is the process of entering the rail. In use, the power component of pull rope and frog are located on both sides of rail respectively, at this time, slide rail 10 is located on the same side with frog. When slide rail 10 is overlapped on rail, the low end of slide rail 10 is flush with the ground, and the high end of slide rail 10 is flush with the upper end surface of rail or the high end of slide rail 10 is higher than the upper end surface of rail, to ensure that the frog can pass over the rail in the process of moving along slide rail 10.

[0028] In one embodiment, slide rail 10 includes two side guards 11 arranged side by side, the two side guards 11 are connected with each other by connecting piece 12, the two side guards 11 have working surface 21 located in the same plane, and the working surface 21 of the two side guards 11 constitutes guide surface 20. Through this embodiment, the working surface 21 on the two side guards 11 with a certain spacing constitutes guide surface 20, which reduces the contact area between frog and slide rail 10 while improving the stability of contact.

[0029] Specifically, the two side guards 11 are parallel to each other, that is, the spacing between the two side guards 11 is uniform, and the connecting piece 12 is in the form of a plate, a plurality of plate structures are arranged between the two side guards 11, and preferably, an included angle is formed between adjacent plate structures to improve the stability of the connecting piece 12 connecting the two side guards 11. The upper end surface of the two side guards 11 is the working surface 21, and the working surface 21 of the two side guards 11 is located in the same plane and constitutes guide surface 20 together. When the frog moves along guide surface 20, the frog can contact the working surface 21 of the two side guards 11 at the same time. The two side guards 11 with a certain spacing support the frog, ensuring the stability of the frog during movement, the space between the two side guards 11 does not interfere with the frog, reducing the friction contact area, and facilitating the movement of the pull rope in the space between the two side guards 11. In the process of moving the frog, a plurality of slide rails 10 can also be arranged according to the length of the frog.

[0030] In one embodiment, two slide rails 10 can be symmetrically arranged to form a whole, the guide surfaces 20 of the two slide rails 10 are respectively located on both sides of the rail, and the top ends of the two slide rails 10 have horizontal surfaces for connecting the two guide surfaces 20. Through this embodiment, the frog moves upward from below through one of the slide rails 10 to cross the rail along the guide surface 20 of the slide rail 10, and after crossing the rail, moves downward from above through the slide rail 10 on the other side, so that the frog can smoothly slide from a high place to the ground, avoiding the safety hazards of damaging the frog itself and injuring the operator caused by falling from a high place.

[0031] Specifically, when the slide rail 10 is arranged on only one side of the rail, although the frog can also cross the rail and move upward from below along the guide surface 20 of the slide rail 10 to the high place of the rail, when moving downward from the high place of the rail, the rail directly falls, which can damage the rail and cause safety hazards to the operator. As shown in FIG. 1, two frogs are combined to form a whole, and the two slide rails 10 are respectively overlapped on both sides of the rail. When the frog moves along one of the slide rails 10 to the high place of the rail, it can smoothly slide downward along the other slide rail 10, avoiding the safety hazards caused by the direct falling of the frog. Figure 3 and 4 The mechanisms of the two slide rails 10 are consistent, and when the rail is a single rail, the two slide rails 10 can be simultaneously overlapped on the single rail, at which time the two slide rails 10 are arranged in a staggered manner, but the upper end surfaces (horizontal surfaces) are located on the same plane. Similarly, when the rail is a double rail, the two slide rails 10 are stacked and placed.

[0032] In one embodiment, a rotatable roller 30 is arranged between the two side guards 11, and the roller 30 is lower than the plane on which the guide surface 20 is located. When the frog is moved by the pulling rope, the pulling rope can be in contact with the outer wall of the roller 30 in the circumferential direction. Through this embodiment, the roller 30 can assist in supporting the pulling rope at the corner and other positions, avoiding the contact and friction between the pulling rope and the sharp corner and other positions, and avoiding the safety hazards such as breakage, so that the pulling rope is more smoothly transitioned at the corner, and the service life of the pulling rope is improved.

[0033] Specifically, the position of the action point of the pulling rope and the power assembly is lower than the upper end surface of the rail, so that in the use process of the pulling rope, the roller 30 ensures that the pulling rope can be smoothly transitioned at the corner, and the roller 30 is rotated to reduce the friction loss between the roller 30 and the pulling rope.

[0034] In one embodiment, the guide surface 20 gradually inclines upward in the direction close to the rail.

[0035] In one embodiment, the slide rail 10 is provided with a limiting groove 40, which is engaged with the rail to form a limiting structure when the slide rail 10 is overlapped with the rail. Through this embodiment, the slide rail 10 forms a limiting structure with the rail when it is overlapped with the rail, and no additional fixing structure is needed for the slide rail 10, which ensures the stability of the slide rail 10 during the movement of the frog, and the structure of the slide rail 10 is simple, and the installation is simple and convenient.

[0036] Specifically, during the movement of the frog, the slide rail 10 is mainly subjected to a transverse component force, and at this time, the limiting groove 40 is engaged with the rail to avoid the transverse position of the slide rail 10, which plays a role in auxiliary fixing of the slide rail 10, and no additional fixing device is needed for the slide rail 10.

[0037] In one embodiment, the power assembly includes a housing 50, the housing 50 is provided with a capstan shaft 51, the end of the pull rope is connected with the capstan shaft 51, and the capstan shaft 51 can rotate to wind the pull rope. Through this embodiment, the pull rope can be stored through the capstan shaft 51, and during the movement of the frog, the pull rope is wound, and the frog is moved by the pull rope, the capstan shaft 51 and the slide rail 10, which is convenient for storage and carrying, and can be used by on-site combination, and the use requirement of the site is low, and it is easy to popularize and use.

[0038] Specifically, the power assembly can be a traction device, such as a traction locomotive, etc., but due to the environmental limitations of the railway track, it is likely that it does not have a large space operation condition. Therefore, the housing 50 and the capstan shaft 51 of the present application are free from environmental display, such as Figure 1 and 2 , the rotation of the capstan shaft 51 can store the pull rope (the pull rope is not shown in the figure), and during the winding of the pull rope, the frog is moved. Figure 2 In this embodiment, the housing 50 includes fixing plates on both sides and a connecting plate between the fixing plates, which are spliced to form the housing 50, and the connecting plate is located outside the capstan shaft 51.

[0039] At the guard rail part of the frog, the pull rope cannot be directly hung to the bottom of the frog due to the shielding of the guard rail, and at this time, a hook plate needs to be arranged at the end of the pull rope for transition connection. No hook plate is needed at the place without guard rail.

[0040] In one embodiment, the side wall of the housing 50 is provided with a fixing box 60, the inside of the fixing box 60 is provided with a turbine 61, the turbine 61 is sleeved on the capstan shaft 51, the fixing box 60 is further provided with a worm 62 which is engaged with the turbine 61, and the worm 62 is detachably connected with a driving assembly. Through this embodiment, the rotation of the capstan shaft 51 is realized through the transmission of the turbine 61 and the worm 62, which ensures the stability of the capstan shaft 51 during winding.

[0041] Specifically, the fixed box 60 is an oil tank. Bearings and positioning sleeves are also fitted at both ends of the worm 62 to improve the stability of the worm 62 during rotation. One end of the winch shaft 51 is connected to the worm wheel. An oil seal structure fitted on the winch shaft 51 is also provided on the housing 50 to seal the internal lubricating oil of the fixed box 60.

[0042] In one embodiment, the drive assembly includes an internal combustion bolt wrench. One end of the worm gear 62 passes through the fixed housing 60 and is fitted with a power input nut 63, which is compatible with the internal combustion bolt wrench. This embodiment allows for a detachable transmission connection between the internal combustion bolt wrench and the winch shaft 51, facilitating separate carrying and use. One internal combustion bolt wrench can be paired with multiple power input nuts 63, reducing the requirements on the equipment.

[0043] Specifically, internal combustion bolt wrenches are commonly used tools in railway maintenance. The power input nut 63 of this application is compatible with internal combustion bolt wrenches. When it is necessary to reel in the rope, the internal combustion bolt wrench is connected to the power input nut 63 to achieve a quick and easy transmission connection with the worm gear 62. When it is not necessary to reel in the rope, the internal combustion bolt wrench is disengaged from the power input nut 63, making disassembly quick and easy. The drive assembly, rope, housing 50, and slide rail 10 are all modular structures, which are simple and convenient to use in combination, and the modular structure facilitates storage and transportation.

[0044] In one embodiment, the housing 50 is further provided with a positioning buckle 52, which can be used to fix the power assembly. In this embodiment, the positioning buckle 52 is located on the side of the housing 50 away from the frog. When the winch shaft 51 moves against the frog to increase power, the positioning buckle 52 can apply a reaction force to the housing 50, thereby improving the stability of the housing 50 during use.

[0045] Specifically, when the slide rail 10 overlaps with one side of the rail, the positioning buckle 52 can engage with the other side of the rail to form a limiting structure, or the positioning buckle 52 can connect with other structures on the rail to apply a force to the housing 50 away from the frog direction, thereby improving the stability of the housing 50. The direction of the pull rope on the winch shaft 51 and the positioning buckle 52 are located on opposite sides of the winch shaft 51.
