[0045] The technical solution of this application will be further described below with reference to specific embodiments and accompanying drawings.

[0046] Please see Figure 1 This application discloses a rail lifting device 1, including a base 11, a support assembly 12, and a lifting assembly 13. The base 11 is used to be disposed below the rail and in a first direction (e.g., Figure 1 The rail is clamped on both sides (as shown in the X direction). The support assembly 12 is disposed on the base 11, and the lifting assembly 13 is disposed on the support assembly 12, and the lifting assembly 13 is used to lift the rail.

[0047] In this application, the rail lifting device 1 can be used to lift frogs or other rail components, and is not limited to this application.

[0048] The first direction can be roughly horizontal and can be roughly perpendicular to the extension direction of the rail component.

[0049] The working principle of this embodiment is as follows:

[0050] First, move the base 11 under the rail to be clamped, then clamp both sides of the rail to fix the base 11 to the rail. The support assembly 12 is installed on the base 11, and the lifting assembly 13 is mounted on the support assembly 12. The lifting device first lifts the old rail from the preset position and places it in the first placement position, then lifts the new rail from the second placement position and places it in the preset position, thus completing the rail replacement.

[0051] In this embodiment, by placing the base 11 under the rail and clamping the two sides of the rail, a stable support is provided for the lifting assembly 13, which avoids the lifting assembly 13 from shifting its center of gravity and causing the rail lifting device 1 to tip over when replacing rail parts, thus preventing safety accidents. At the same time, the rail lifting device 1 can save manpower and improve handling efficiency.

[0052] Please continue reading. Figure 1 In some embodiments, the base 11 includes a main body 111, which is disposed below the rail. The upper surface of the main body 111 is provided with a first clamping member 112 and a second clamping member 113. The first clamping member 112 is fixedly disposed on the main body 111, and the second clamping member 113 is detachably disposed on the main body 111. The first clamping member 112 and the second clamping member 113 respectively clamp the two sides of the rail in a first direction.

[0053] The working principle of this embodiment is as follows:

[0054] Before installing the base 11, remove the second clamp 113 from the main body 111.

[0055] The main body 111 without the second clamping member 113 is moved to the underside of the rail to be clamped, and then moved laterally in the first direction until the first clamping member 112 abuts against the surface of one side of the rail. The second clamping member 113 is then installed on the main body 111, at which point it abuts against the surface of the other side of the rail, so that the first clamping member 112 and the second clamping member 113 clamp the surfaces of both sides of the rail, thereby fixing the main body 111 of the base 11 to the rail.

[0056] Support component 12 is installed on base 11, and lifting component 13 is set on support component 12. The lifting device first lifts the old rail component at the preset position and places it in the first placement position, then lifts the new rail component at the second placement position and places it in the preset position, thereby completing the replacement of the rail component.

[0057] In this embodiment, the main body 111 of the base 11 is placed under the rail, and the two sides of the rail are clamped by the first clamping member 112 and the second clamping member 113, which provides stable support for the lifting assembly 13. This avoids the lifting assembly 13 from shifting its center of gravity when replacing rail parts, which could cause the rail lifting device 1 to tip over and prevent safety accidents. At the same time, the rail lifting device 1 can save manpower and improve handling efficiency.

[0058] In some other embodiments, the second clamping member 113 may be slidably disposed on the main body 111 and may be close to or away from the first clamping member 112.

[0059] Please refer to the following: Figure 1 and Figure 2 In some embodiments, the base 11 also includes a second direction (e.g., Figure 2 A rod 114 extending in the Y direction (as shown in the middle) is connected to one end of the main body 111, and both ends of the rod 114 are provided with a function that can extend in a third direction (such as...). Figure 1 The support rod 115 moves in the Z direction (as shown in the middle), wherein the second direction is perpendicular to the first direction and perpendicular to the third direction.

[0060] The second direction can be approximately horizontal and parallel to the extension direction of the rail component. The third direction can be approximately perpendicular to the vertical direction.

[0061] In addition, the support rod 115 can be threaded into the base 11.

[0062] The working principle of this embodiment is as follows:

[0063] Before installing the base 11, remove the second clamp 113 from the main body 111.

[0064] The main body 111 without the second clamping member 113 is first moved between the two rails. In other words, the main body 111 without the second clamping member 113 is first moved to the inside of the rail to be clamped, then moved to the bottom of the rail to be clamped and moved laterally in the first direction until the first clamping member 112 abuts against the surface of one side of the rail to be clamped. At this time, the first clamping member 112 is located between the two rails, that is, the first clamping member 112 is located on the inside of the rail to be clamped. Then, the second clamping member 113 is installed on the main body 111. At this time, the second clamping member 113 abuts against the surface of the other side of the rail to be clamped. In other words, the second clamping member 113 is located on the outside of the rail to be clamped, so that the first clamping member 112 and the second clamping member 113 respectively clamp the inner and outer surfaces of the rail to be clamped, thereby fixing the main body 111 of the base 11 to the rail.

[0065] It should be noted that, at this point, the base 11 is installed on the upper surface of two adjacent sleepers. Since the portion of the sleeper's upper surface between the two rails is not flat, the contact area between the base 11 and the sleepers may be too small, resulting in insufficient support from the sleepers for the base 11. To solve this problem, the two support rods 115 can be moved along a third direction, so that the bottom surfaces of the two support rods 115 abut against the upper surfaces of the two sleepers respectively, thereby improving the support for the base 11.

[0066] Support component 12 is installed on base 11, and lifting component 13 is set on support component 12. The lifting device first lifts the old rail component at the preset position and places it in the first placement position, then lifts the new rail component at the second placement position and places it in the preset position, thereby completing the replacement of the rail component.

[0067] In this embodiment, the main body 111 of the base 11 is placed under the rail, and the two sides of the rail are clamped by the first clamping member 112 and the second clamping member 113. At the same time, the support rod 115 abuts against the upper surface of the sleeper, providing stable support for the lifting assembly 13. This prevents the lifting assembly 13 from shifting its center of gravity when replacing rail parts, thus avoiding the rail lifting device 1 from tipping over and preventing safety accidents. At the same time, the rail lifting device 1 can save manpower and improve handling efficiency.

[0068] In some other embodiments, the support rod 115 may be disposed on the main body 111 of the base 11.

[0069] In other embodiments, the rod portion 114 has a first surface 1141 and a second surface 1142 facing away from each other, and the main body portion 111 is connected to the first surface 1141. The base 11 also includes a first support plate 1191 and a second support plate 1192, the first support plate 1191 being connected to the first surface 1141 and the main body portion 111, and the second support plate 1192 being connected to the second surface 1142, and the lower surfaces of the first support plate 1141, the second support plate 1192, the rod portion 114, and the main body portion 111 are coplanar.

[0070] The working principle of this embodiment is as follows:

[0071] Before installing the base 11, remove the second clamp 113 from the main body 111.

[0072] The main body 111 without the second clamping member 113 is first moved to the side of the rail to be clamped that is away from the matching rail. In other words, the main body 111 without the second clamping member 113 is first moved to the outside of the rail to be clamped, then moved to the bottom of the rail to be clamped and moved laterally in the first direction until the first clamping member 112 abuts against the surface of one side of the rail to be clamped. At this time, the first clamping member 112 is located on the outside of the rail to be clamped. Then, the second clamping member 113 is installed on the main body 111. At this time, the second clamping member 113 abuts against the surface of the other side of the rail to be clamped. In other words, the second clamping member 113 is located on the inside of the rail to be clamped, so that the first clamping member 112 and the second clamping member 113 clamp the outer and inner surfaces of the rail to be clamped respectively, thereby fixing the main body 111 of the base 11 to the rail.

[0073] It should be noted that at this time, the base 11 is supported by the ballast layer. Since the ballast layer is composed of multiple pieces of crushed ballast, the support rod 115 cannot provide support for the base 11. However, the first support plate 1191 and the second support plate 1192 can increase the contact area between the base 11 and the ballast layer, thereby improving the support effect on the base 11.

[0074] Support component 12 is installed on base 11, and lifting component 13 is set on support component 12. The lifting device first lifts the old rail component at the preset position and places it in the first placement position, then lifts the new rail component at the second placement position and places it in the preset position, thereby completing the replacement of the rail component.

[0075] In this embodiment, the main body 111 of the base 11 is placed under the rail, and the two sides of the rail are clamped by the first clamping member 112 and the second clamping member 113. At the same time, the first support plate 1191 and the second support plate 1192 can increase the contact area between the base 11 and the ballast layer, providing stable support for the lifting assembly 13. This prevents the lifting assembly 13 from shifting its center of gravity when replacing rail parts, thus avoiding the rail lifting device 1 from tipping over and preventing safety accidents. At the same time, the rail lifting device 1 can save manpower and improve handling efficiency.

[0076] Please see Figure 2 In some embodiments, the main body 111 is located between two adjacent sleepers. The rod 114 is provided with two first support members 116, which are located on both sides of the main body 111 in the second direction, and the two first support members 116 overlap the upper surface of the sleepers on both sides of the main body 111.

[0077] The working principle of this embodiment is as follows:

[0078] Before installing the base 11, remove the second clamp 113 from the main body 111.

[0079] The main body 111 without the second clamping member 113 is moved to the underside of the rail to be clamped, and then moved laterally in the first direction until the first clamping member 112 abuts against the surface of one side of the rail. The base 11 is moved in the second direction until the two first support members 116 are respectively placed on the upper surfaces of the sleepers on both sides of the main body 111. The second clamping member 113 is then installed on the main body 111, at which point the second clamping member 113 abuts against the surface of the other side of the rail, so that the first clamping member 112 and the second clamping member 113 clamp the surfaces of both sides of the rail, thereby fixing the main body 111 of the base 11 to the rail.

[0080] Support component 12 is installed on base 11, and lifting component 13 is set on support component 12. The lifting device first lifts the old rail component at the preset position and places it in the first placement position, then lifts the new rail component at the second placement position and places it in the preset position, thereby completing the replacement of the rail component.

[0081] In this embodiment, the main body 111 of the base 11 is placed under the rail, and the position of the main body 111 is adjusted so that the two first support members 116 respectively overlap the upper surface of the sleepers on both sides of the main body 111. The two sides of the rail are clamped by the first clamping member 112 and the second clamping member 113, which provides stable support for the lifting assembly 13. This avoids the lifting assembly 13 from shifting its center of gravity when replacing rail parts, which could cause the rail lifting device 1 to tip over and prevent safety accidents. At the same time, the rail lifting device 1 can save manpower and improve handling efficiency.

[0082] In some other embodiments, the two first support members 116 may overlap the upper surface of the rail.

[0083] Please continue reading. Figure 2 In some embodiments, a second support 117 is provided at one end of the first support member 116 away from the rod 114 in a first direction. The second support member 117 extends along a second direction, and both ends of the second support member 117 protrude from both sides of the sleeper. The portions of the two ends of the second support member 117 that protrude from the sleeper are provided with grippers 14 that can move along a third direction. The grippers 14 are used to hold the sleeper.

[0084] The working principle of this embodiment is as follows:

[0085] Before installing the base 11, remove the second clamp 113 from the main body 111.

[0086] The main body 111 without the second clamping member 113 is moved to the underside of the rail to be clamped, and then moved laterally in the first direction until the first clamping member 112 abuts against the surface of one side of the rail. The base 11 is moved in the second direction until the two first support members 116 are respectively placed on the upper surfaces of the sleepers on both sides of the main body 111, and the clamping jaws 14 are moved vertically to clamp the sleepers. The second clamping member 113 is then installed on the main body 111, at which point the second clamping member 113 abuts against the surface of the other side of the rail, so that the first clamping member 112 and the second clamping member 113 clamp the surfaces of both sides of the rail, thereby fixing the main body 111 of the base 11 to the rail.

[0087] Support component 12 is installed on base 11, and lifting component 13 is set on support component 12. The lifting device first lifts the old rail component at the preset position and places it in the first placement position, then lifts the new rail component at the second placement position and places it in the preset position, thereby completing the replacement of the rail component.

[0088] The gripper 14 may include a rod 141, a gripper portion 142, and a locking portion 143. The rod 141 is disposed on the portion of the second support member that protrudes from the sleeper and can move along a third direction. The gripper portion 142 and the locking portion 143 are respectively connected to the rod 141, and the gripper portion 142 and the locking portion 143 are respectively located on both sides of the second support member in the third direction. The specific process of the gripper 14 gripping the sleeper is as follows: first, the rod 141 is moved along the third direction and rotated simultaneously to adjust the position of the gripper portion 142 and make the gripper portion 142 abut against the lower surface of the sleeper. Then, the locking portion 143 locks the rod 141, so that the gripper portion 142 can be stably gripped on the lower surface of the sleeper, thereby further fixing the base 11.

[0089] In this embodiment, the main body 111 of the base 11 is placed under the rail, and the two sides of the rail are clamped by the first clamping member 112 and the second clamping member 113, and the sleepers are clamped by the jaws 14. This provides stable support for the lifting assembly 13, and avoids the lifting assembly 13 from shifting its center of gravity when replacing rail parts, which could cause the rail lifting device 1 to tip over, thus preventing safety accidents. At the same time, the rail lifting device 1 can save manpower and improve handling efficiency.

[0090] In some other embodiments, a gripper 14 for holding a sleeper may also be provided at the end of the first support 116 away from the rod 114 in the first direction.

[0091] Please refer to it again. Figure 1In some embodiments, the support assembly 12 includes a column 121 and a support frame 122. The column 121 is detachably mounted on the base 11. The support frame 122 is rotatably connected to the column 121 and can rotate about the central axis of the column 121. The lifting assembly 13 is mounted on the support frame 122.

[0092] The working principle of this embodiment is as follows:

[0093] First, move the base 11 to the bottom of the rail to be clamped, and then clamp the two sides of the rail to fix the base 11 to the rail.

[0094] The column 121 of the support assembly 12 is installed on the base 11, the support frame 122 is installed on the column 121, and the lifting assembly 13 is placed on the support frame 122.

[0095] The lifting device first lifts the old rail component at the preset position. The support frame 122 rotates around the central axis of the column 121 by a first preset angle and places the old rail component in the first placement position. Then, the new rail component at the second placement position is lifted. The support frame 122 rotates by a second preset angle and places the new rail component in the preset position, thereby completing the replacement of the rail component.

[0096] In this embodiment, by placing the base 11 under the rail and clamping the two sides of the rail, a stable support is provided for the lifting assembly 13, which avoids the lifting assembly 13 from shifting its center of gravity and causing the rail lifting device 1 to tip over when replacing rail parts, thus preventing safety accidents. At the same time, the support frame 122 can save manpower and improve handling efficiency when rotating and transporting rail parts.

[0097] In some other embodiments, the column 121 can be rotatably mounted on the base 11.

[0098] Please refer to the following: Figure 2 , Figure 3 and Figure 4 In some embodiments, the base 11 is provided with a slide rail 118 extending in a first direction, and the column 121 is provided with a groove 1211 that mates with the slide rail 118. The column 121 is configured to move along the slide rail 118 when the groove 1211 mates with the slide rail 118.

[0099] The working principle of this embodiment is as follows:

[0100] First, move the base 11 to the bottom of the rail to be clamped, and then clamp the two sides of the rail to fix the base 11 to the rail.

[0101] Align the slide groove 1211 with the slide rail 118 and make the slide groove 1211 engage with the slide rail 118. Then move the column 121 along the slide rail 118 so that the column 121 is installed on the base 11. Then install the support frame 122 on the column 121 and set the lifting assembly 13 on the support frame 122.

[0102] The lifting device first lifts the old rail component at the preset position. The support frame 122 rotates around the central axis of the column 121 by a first preset angle and places the old rail component in the first placement position. Then, the new rail component at the second placement position is lifted. The support frame 122 rotates by a second preset angle and places the new rail component in the preset position, thereby completing the replacement of the rail component.

[0103] In this embodiment, by placing the base 11 below the rail and clamping the two sides of the rail, a stable support is provided for the lifting assembly 13. This prevents the lifting assembly 13 from shifting its center of gravity during rail replacement, thus avoiding the rail lifting device 1 from tipping over and preventing safety accidents. Simultaneously, the rotating support frame 122 can save manpower and improve handling efficiency when transporting rail components. Furthermore, by setting the slide groove 1211 and the slide rail 118, this embodiment allows the column 121 to move along the slide rail 118, thereby reducing the difficulty of installing the column 121.

[0104] In some other embodiments, the slide 1211 can be disposed on the base 11, and the slide rail 118 can be disposed on the column 121.

[0105] Please refer to the following: Figure 1 , Figure 3 and Figure 4 In some embodiments, the column 121 is connected to a reinforcing plate 123, and a limiting block 124 is provided at the bottom of the reinforcing plate 123, the limiting block 124 protruding from the reinforcing plate 123 in a first direction. When the column 121 is assembled to the base 11, the reinforcing plate 123 abuts against the end face of the base 11, and the limiting block 124 abuts against the lower surface of the base 11.

[0106] The working principle of this embodiment is as follows:

[0107] First, move the base 11 to the bottom of the rail to be clamped, and then clamp the two sides of the rail to fix the base 11 to the rail.

[0108] Align the slide groove 1211 with the slide rail 118 and make the slide groove 1211 engage with the slide rail 118. Then move the column 121 along the slide rail 118. During the movement of the column 121, the reinforcing plate 123 gradually approaches the end face of the base 11 until the reinforcing plate abuts against the end face of the base 11. At the same time, the limiting block 124 abuts against the lower surface of the base 11, thereby allowing the column 121 to be installed on the base 11. Then install the support frame 122 on the column 121 and set the lifting assembly 13 on the support frame 122.

[0109] The lifting device first lifts the old rail component at the preset position. The support frame 122 rotates around the central axis of the column 121 by a first preset angle and places the old rail component in the first placement position. Then, the new rail component at the second placement position is lifted. The support frame 122 rotates by a second preset angle and places the new rail component in the preset position, thereby completing the replacement of the rail component.

[0110] In this embodiment, by placing the base 11 below the rail and clamping the two sides of the rail, a stable support is provided for the lifting assembly 13. This prevents the lifting assembly 13 from shifting its center of gravity during rail replacement, thus avoiding the rail lifting device 1 from tipping over and preventing safety accidents. Simultaneously, the rotating support frame 122 can save manpower and improve handling efficiency when transporting rail components. Furthermore, this embodiment includes a reinforcing plate 123, allowing the column 121 to move to the installation position of the support frame 122 and stop during sliding, thereby improving the installation accuracy of the column 121. In addition, the limiting block 124 can limit the movement of the column 121.

[0111] In some other embodiments, a receiving groove can be provided on the end face of the base 11, and when the column 121 is assembled on the base 11, the limiting block 124 is embedded in the receiving groove.

[0112] Please refer to it again. Figure 1 In some embodiments, the support frame 122 includes a sleeve 1221, a cantilever 1222, and a diagonal rod 1223. The sleeve 1221 is fitted onto the column 121 and is rotatable about the central axis of the column 121. The cantilever 1222 is disposed on the top surface of the sleeve 1221, and the lifting assembly 13 is disposed on the cantilever 1222. One end of the diagonal rod 1223 is connected to the outer surface of the sleeve 1221, and the other end of the diagonal rod 1223 is connected to the cantilever 1222.

[0113] The diagonal brace 1223 is inclined relative to both the sleeve 1221 and the cantilever 1222, forming a triangular structure among the diagonal brace 1223, the cantilever 1222, and the sleeve 1221. This prevents the cantilever 1222 from deforming or tilting when the lifting assembly 13 lifts the rail component, ensuring the stability of the cantilever 1222. Furthermore, the two ends of the diagonal brace 1223 are connected to the sleeve 1221 and the cantilever 1222 respectively, further distributing the load and preventing excessive load at the connection between the sleeve 1221 and the cantilever 1222.

[0114] In some other implementations, a counterweight may be added to the end of the cantilever 1222 away from the force-bearing end.

[0115] Please continue reading. Figure 1In some embodiments, the lifting assembly 13 includes a hook 131, a hydraulic cylinder 133, and a first load-bearing chain 132. The hook 131 is used to hook and lift rail components, the hydraulic cylinder 133 is disposed on the cantilever 1222, one end of the first load-bearing chain 132 is connected to the hook 131, and the first load-bearing chain 132 is detachably connected to the hydraulic cylinder 133. The hydraulic cylinder 133 can drive the hook 131 to rise or fall via the first load-bearing chain 132.

[0116] The first load-bearing chain 132 can be an iron chain or made of other metals with high strength, and there is no limitation on it.

[0117] The working principle of this embodiment is as follows:

[0118] First, detach the first load-bearing chain 132 from the hydraulic cylinder, hook the hook 131 onto the old rail component, and simultaneously extend the piston rod of the hydraulic cylinder 133. Then, straighten the first load-bearing chain 132 and connect it to the piston rod. The piston rod of the hydraulic cylinder 133 shortens, causing the hook 131 to rise via the first load-bearing chain 132 to lift the old rail component. The hydraulic cylinder 133 then extends the piston rod, causing the first load-bearing chain 132 to lower the hook 131, allowing the old rail component to descend to the first placement position. The hook 131 then separates from the old rail component, allowing the old rail component to be placed in the first placement position. At the same time, the first load-bearing chain 132 can be detached from the hydraulic cylinder.

[0119] After placing the old rail component in the first placement position, hook 131 is used to hook the new rail component. Simultaneously, the piston rod of hydraulic cylinder 133 is extended, and the first load-bearing chain 132 is taut and connected to the piston rod. The piston rod of hydraulic cylinder 133 shortens, driving hook 131 to rise via the first load-bearing chain 132 to lift the new rail component. After the new rail component is lifted, hydraulic cylinder 133 drives hook 131 to descend via the first load-bearing chain 132 to install the new rail component into the preset position.

[0120] It should be noted that the position where the first bearing chain 132 is taut and connected to the piston rod can be the end of the first bearing chain 132 or other positions of the first bearing chain 132.

[0121] By connecting the first load-bearing chain 132 to the hydraulic cylinder 133 and driving the hook 131 to rise or fall, the lifting efficiency can be significantly improved. At the same time, the first load-bearing chain 132 can withstand a large load, ensuring that the lifting assembly 13 will not break during the lifting process.

[0122] In some other embodiments, the hydraulic cylinder 133 may be replaced by a pneumatic cylinder or the like.

[0123] Please continue reading. Figure 1In some embodiments, there are two hooks 131, which are used to hook the two sides of the lifting rail component. The lifting assembly 13 also includes a lifting ring 134 and two second load-bearing chains 135. The lifting ring 134 is connected to the end of the first load-bearing chain 132 away from the hydraulic cylinder 133. One end of each of the two second load-bearing chains 135 is connected to the lifting ring 134, and the other end of each of the two second load-bearing chains 135 is connected to the two hooks 131 respectively.

[0124] The two hooks 131, positioned on either side of the rail component, balance the rail component during lifting, reducing potential swaying or tilting and improving safety. Simultaneously, the two hooks 131 distribute the load across them, preventing damage from excessive load on any single hook. Furthermore, the two second load-bearing chains 135 connect the two hooks 131 respectively, allowing for easy adjustment of the distance between them to accommodate rail components of different widths or shapes, thus expanding the applicability of the rail lifting device 1.

[0125] In some other embodiments, there are two first carrier chains 132, one end of each first carrier chain 132 is connected to a hydraulic cylinder 133, and the other end of each first carrier chain 132 is connected to two hooks 131.
