[0045] The technical solution of the present application will be further described below in conjunction with specific embodiments and drawings.

[0046] See also Figure 1 The present application embodiment 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 arranged under the rail and in a first direction (such as Figure 1 The support assembly 12 is arranged on the base 11, and the lifting assembly 13 is arranged on the support assembly 12, and the lifting assembly 13 is used to lift the rail member.

[0047] In the present application, the rail lifting device 1 can be used for lifting frogs, and can also be used for lifting other rails, which is not limited here.

[0048] The first direction may be substantially a horizontal direction, and the first direction may be substantially perpendicular to an extension direction of the rail.

[0049] The working principle of this embodiment is:

[0050] First, the base 11 is moved to the lower side of the rail to be clamped, and then the two side surfaces of the rail are clamped, so that the base 11 is fixed to the rail. The support assembly 12 is installed on the base 11, and the lifting assembly 13 is arranged on the support assembly 12. The lifting device first lifts the old rail member at the preset position and places it in the first placement position, and then lifts the new rail member at the second placement position and places the new rail member at the preset position, so as to complete the replacement of the rail member.

[0051] This embodiment provides stable support for the lifting assembly 13 by placing the base 11 under the rail and clamping the two side surfaces of the rail, thereby preventing the lifting assembly 13 from shifting its center of gravity when replacing the rail and causing the rail lifting device 1 to tip over, thereby 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 used to be set under the rail. A first clamping member 112 and a second clamping member 113 are set on the upper surface of the main body 111. The first clamping member 112 is fixedly set on the main body 111, and the second clamping member 113 is detachably set on the main body 111. The first clamping member 112 and the second clamping member 113 respectively clamp the two side surfaces of the rail in the first direction.

[0053] The working principle of this embodiment is:

[0054] Before installing the base 11 , the second clamping member 113 is detached from the main body 111 .

[0055] The main body 111 without the second clamping member 113 is moved to the bottom of the rail to be clamped, and is 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, and 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.

[0056] The support assembly 12 is mounted on the base 11, and the lifting assembly 13 is disposed on the support assembly 12. The lifting device first lifts the old rail member at the preset position and places it at the first placement position, then lifts the new rail member at the second placement position and places the new rail member at the preset position, thereby completing the replacement of the rail member.

[0057] This embodiment provides stable support for the lifting assembly 13 by placing the main body 111 of the base 11 under the rail and clamping the two side surfaces of the rail through the first clamping member 112 and the second clamping member 113, thereby preventing the lifting assembly 13 from shifting its center of gravity when replacing the rail and causing the rail lifting device 1 to tip over, thereby preventing 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 also read Figure 1 and Figure 2 In some embodiments, the base 11 further includes a Figure 2 The rod 114 is connected to one end of the main body 111, and both ends of the rod 114 are provided with a third direction (as shown in the Y direction). Figure 1 A support rod 115 is movable in the second direction (as shown in the Z direction), wherein the second direction is perpendicular to the first direction and perpendicular to the third direction.

[0060] The second direction may be substantially horizontal, and the second direction may be substantially parallel to the extension direction of the rail member. The third direction may be substantially perpendicular to the vertical direction.

[0061] In addition, the support rod 115 can be engaged with the base 11 through threads.

[0062] The working principle of this embodiment is:

[0063] Before installing the base 11 , the second clamping member 113 is detached 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 inner side of the rail to be clamped, and then moved to the bottom of the rail to be clamped and moved laterally along 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 inner side 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, at this time, the second clamping member 113 is located on the outer side of the rail to be clamped, so that the first clamping member 112 and the second clamping member 113 are respectively clamped on 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 the base 11 is installed on the upper surface of two adjacent sleepers at this time. Since the upper surface of the sleeper between the two rails is not a plane, when the base 11 is installed on the upper surface of two adjacent sleepers, the contact area between the base 11 and the sleeper is small, resulting in insufficient support of the sleeper to the base 11. In order to solve this problem, the two support rods 115 can be moved along the third direction so that the bottom surfaces of the two support rods 115 are respectively in contact with the upper surfaces of the two sleepers, thereby improving the support effect on the base 11.

[0066] The support assembly 12 is mounted on the base 11, and the lifting assembly 13 is disposed on the support assembly 12. The lifting device first lifts the old rail member at the preset position and places it at the first placement position, then lifts the new rail member at the second placement position and places the new rail member at the preset position, thereby completing the replacement of the rail member.

[0067] In this embodiment, the main body 111 of the base 11 is placed under the rail, and the two side surfaces of the rail are clamped by the first clamping member 112 and the second clamping member 113, and the support rod 115 is abutted against the upper surface of the sleeper, thereby providing stable support for the lifting assembly 13, avoiding the center of gravity shift of the lifting assembly 13 when replacing the rail, causing the rail lifting device 1 to tip over, and preventing safety accidents. At the same time, the rail lifting device 1 can save manpower and improve transportation 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 opposite to each other, and the main body 111 is connected to the first surface 1141. The base 11 further includes a first support plate 1191 and a second support plate 1192, the first support plate 1191 is connected to the first surface 1141 and the main body 111, the second support plate 1192 is connected to the second surface 1142, and the lower surface of the first support plate 1141, the lower surface of the second support plate 1192, the lower surface of the rod portion 114, and the lower surface of the main body 111 are coplanar.

[0070] The working principle of this embodiment is:

[0071] Before installing the base 11 , the second clamping member 113 is detached 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 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, and then moved to the bottom of the rail to be clamped and moved laterally along 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, at this time, 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 are respectively clamped on the surfaces of the outer and inner sides of the rail to be clamped, 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, and since the ballast layer is formed by multiple crushed ballasts, the support rod 115 cannot provide support for the base 11 at this time. However, at this 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, thereby improving the supporting effect on the base 11.

[0074] The support assembly 12 is mounted on the base 11, and the lifting assembly 13 is disposed on the support assembly 12. The lifting device first lifts the old rail member at the preset position and places it at the first placement position, then lifts the new rail member at the second placement position and places the new rail member at the preset position, thereby completing the replacement of the rail member.

[0075] In this embodiment, the main body 111 of the base 11 is placed under the rail, and the two side surfaces 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, thereby providing stable support for the lifting assembly 13, avoiding the center of gravity shift of the lifting assembly 1 when replacing the rail, causing the rail lifting device 1 to tip over, and preventing safety accidents. At the same time, the rail lifting device 1 can save manpower and improve handling efficiency.

[0076] See also 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 respectively located on both sides of the main body 111 in the second direction, and the two first support members 116 are respectively overlapped on the upper surfaces of the sleepers on both sides of the main body 111.

[0077] The working principle of this embodiment is:

[0078] Before installing the base 11 , the second clamping member 113 is detached from the main body 111 .

[0079] Move the main body 111 without the second clamping member 113 to the bottom of the rail to be clamped, and move it transversely in the first direction until the first clamping member 112 abuts against the surface of one side of the rail. Move the base 11 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. Then install the second clamping member 113 on the main body 111, and the second clamping member 113 abuts against the surface on the other side of the rail, so that the first clamping member 112 and the second clamping member 113 clamp the surfaces on both sides of the rail, thereby fixing the main body 111 of the base 11 to the rail.

[0080] The support assembly 12 is mounted on the base 11, and the lifting assembly 13 is disposed on the support assembly 12. The lifting device first lifts the old rail member at the preset position and places it at the first placement position, then lifts the new rail member at the second placement position and places the new rail member at the preset position, thereby completing the replacement of the rail member.

[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 are respectively overlapped on the upper surfaces of the sleepers on both sides of the main body 111, and the first clamping member 112 and the second clamping member 113 clamp the two side surfaces of the rail, thereby providing stable support for the lifting assembly 13, avoiding the center of gravity shift of the lifting assembly 1 when replacing the rail, causing the rail lifting device 1 to tip over, and preventing safety accidents. At the same time, the rail lifting device 1 can save manpower and improve the 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 member 117 is provided at one end of the first support member 116 away from the rod portion 114 in the first direction, and the second support member 117 extends along the second direction, and both ends of the second support member 117 protrude from both sides of the sleeper respectively, and the parts of the second support member 117 protruding from the sleeper at both ends are provided with clamps 14 that can move along the third direction, and the clamps 14 are used to clamp the sleeper.

[0084] The working principle of this embodiment is:

[0085] Before installing the base 11 , the second clamping member 113 is detached from the main body 111 .

[0086] Move the main body 111 without the second clamping member 113 to the bottom of the rail to be clamped, and move it horizontally in the first direction until the first clamping member 112 abuts against the surface of one side of the rail. Move the base 11 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 move the clamping jaws 14 in the vertical direction so that the clamping jaws 14 clamp the sleepers. Then install the second clamping member 113 on the main body 111, and at this time, the second clamping member 113 abuts against the surface on the other side of the rail, so that the first clamping member 112 and the second clamping member 113 clamp the surfaces on both sides of the rail, thereby fixing the main body 111 of the base 11 to the rail.

[0087] The support assembly 12 is mounted on the base 11, and the lifting assembly 13 is disposed on the support assembly 12. The lifting device first lifts the old rail member at the preset position and places it at the first placement position, then lifts the new rail member at the second placement position and places the new rail member at the preset position, thereby completing the replacement of the rail member.

[0088] The clamp 14 may include a rod 141, a clamping claw portion 142 and a locking portion 143, wherein the rod 141 is disposed on a portion of the second support member protruding from the sleeper and can move along a third direction, the clamping claw portion 142 and the locking portion 143 are respectively connected to the rod 141, and the clamping claw portion 142 and the locking portion 143 are respectively located on both sides of the second support member in the third direction. The process of the clamp 14 clamping the sleeper is specifically as follows: first, the rod 141 is moved along the third direction and the rod 141 is rotated at the same time to adjust the position of the clamping claw portion 142 and make the clamping claw portion 142 abut against the lower surface of the sleeper, and then the locking portion 143 locks the rod 141 so that the clamping claw portion 142 can be stably clamped on the lower surface of the sleeper, thereby further fixing the base 11.

[0089] This embodiment provides stable support for the lifting assembly 13 by placing the main body 111 of the base 11 under the rail, clamping the two side surfaces of the rail through the first clamping member 112 and the second clamping member 113, and clamping the sleeper with the clamping claw 14, so as to avoid the center of gravity shift of the lifting assembly 13 when replacing the rail, causing the rail lifting device 1 to tip over, thereby preventing safety accidents. At the same time, the rail lifting device 1 can save manpower and improve transportation efficiency.

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

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

[0092] The working principle of this embodiment is:

[0093] First, the base 11 is moved to the bottom of the rail to be clamped, and then the two side surfaces of the rail are clamped, so as to fix the base 11 to the rail.

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

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

[0096] This embodiment provides stable support for the lifting assembly 13 by placing the base 11 under the rail and clamping the two side surfaces of the rail, thereby preventing the lifting assembly 13 from shifting its center of gravity when replacing the rail and causing the rail lifting device 1 to tip over, thereby preventing safety accidents. At the same time, the support frame 122 rotates to transport the rail, which can save manpower and improve transportation efficiency.

[0100] First, the base 11 is moved to the bottom of the rail to be clamped, and then the two side surfaces of the rail are clamped, so as 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 match 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 at the preset position, the support frame 122 rotates the first preset angle around the central axis of the column 121 and places the old rail in the first position, and then lifts the new rail at the second position, the support frame 122 rotates the second preset angle and places the new rail at the preset position, thereby completing the replacement of the rail.

[0103] This embodiment provides stable support for the lifting assembly 13 by placing the base 11 under the rail and clamping the two side surfaces of the rail, thereby preventing the lifting assembly 13 from shifting its center of gravity when replacing the rail and causing the rail lifting device 1 to tip over, thereby preventing safety accidents. At the same time, the support frame 122 rotates to transport the rail, which can save manpower and improve the transportation efficiency. In addition, this embodiment provides the slide groove 1211 and the slide rail 118, so that the column 121 can move along the slide rail 118, thereby reducing the difficulty of installing the column 121.

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

When the column 121 is assembled to the base 11, the reinforcing plate 123 abuts against the end surface of the base 11, and the limit block 124 abuts against the lower surface of the base 11.

[0106] The working principle of this embodiment is:

[0107] First, the base 11 is moved to the bottom of the rail to be clamped, and then the two side surfaces of the rail are clamped, so as 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 match 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 surface of the base 11 until the reinforcing plate abuts against the end surface of the base 11, and the limit block 124 abuts against the lower surface of the base 11, 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.

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

[0110] This embodiment provides stable support for the lifting assembly 13 by placing the base 11 under the rail and clamping the two side surfaces of the rail, thereby preventing the lifting assembly 13 from shifting its center of gravity when replacing the rail and causing the rail lifting device 1 to tip over, thereby preventing safety accidents. At the same time, the support frame 122 rotates to transport the rail, which can save manpower and improve the transportation efficiency. In addition, this embodiment is provided with a reinforcing plate 123, so that the column 121 can stop after moving the support frame 122 to the installation position during the sliding process, thereby improving the accuracy of the installation of the column 121. In addition, the limit block 124 can limit the column 121.

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

[0112] Please refer again Figure 1 In some embodiments, the support frame 122 includes a sleeve 1221, a cantilever 1222, and an inclined rod 1223. The sleeve 1221 is sleeved on the column 121 and can rotate around 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 inclined rod 1223 is connected to the outer side surface of the sleeve 1221, and the other end of the inclined rod 1223 is connected to the cantilever 1222.

[0113] The inclined rod 1223 is inclined relative to the sleeve 1221 and the cantilever 1222, so that a triangular structure can be formed between the inclined rod 1223, the cantilever 1222 and the sleeve 1221, which prevents the cantilever 1222 from being deformed or tilted when the lifting assembly 13 lifts the rail, thereby ensuring the stability of the cantilever 1222. At the same time, the two ends of the inclined rod 1223 are respectively connected to the sleeve 1221 and the cantilever 1222, which can further disperse the load and avoid excessive load at the connection between the sleeve 1221 and the cantilever 1222.

[0114] In some other embodiments, 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 cylinder 133, and a first load-bearing chain 132. The hook 131 is used to hook the rail, the 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 cylinder 133. The cylinder 133 can drive the hook 131 to rise or fall through the first load-bearing chain 132.

[0116] The first load-bearing chain 132 may be an iron chain, or may be made of other metals with greater strength, which is not limited here.

[0117] The working principle of this embodiment is:

[0118] First, the first load-bearing chain 132 is detached from the oil cylinder, the hook 131 is hooked on the old rail, and the piston rod of the oil cylinder 133 is extended at the same time, and then the first load-bearing chain 132 is straightened and connected to the piston rod. The piston rod of the oil cylinder 133 is shortened to drive the hook 131 to rise through the first load-bearing chain 132 to lift the old rail. The oil cylinder 133 then extends the piston rod to make the first load-bearing chain 132 drive the hook 131 to descend, so that the old rail descends to the first placement position, and the hook 131 is separated from the old rail, so that the old rail is placed in the first placement position, and the first load-bearing chain 132 can be detached from the oil cylinder at the same time.

[0119] After placing the old rail at the first placement position, hook the new rail with the hook 131, and at the same time, extend the piston rod of the oil cylinder 133, and then straighten the first load-bearing chain 132 and connect it to the piston rod. The piston rod of the oil cylinder 133 is shortened to drive the hook 131 upward through the first load-bearing chain 132 to lift the new rail. After the new rail is lifted, the oil cylinder 133 drives the hook 131 downward through the first load-bearing chain 132 to install the new rail to the preset position.

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

[0121] By connecting the first load-bearing chain 132 through the oil 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 component 13 will not break during the lifting process.

[0122] In some other embodiments, the oil cylinder 133 may also be replaced by a gas cylinder or the like.

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

[0124] The two hooks 131 hook the two sides of the rail, which can balance the rail when lifting the rail, reduce the shaking or tilting of the rail during lifting, and improve the safety of the lifting process. At the same time, the two hooks 131 hook the rail can disperse the load on the hook 131, and prevent a single hook 131 from being damaged by excessive load. In addition, the two second load chains 135 are respectively connected to the two hooks 131, and the distance between the two hooks 131 can be easily adjusted to adapt to rails of different widths or shapes, thereby expanding the scope of application of the rail lifting device 1.

[0125] In some other embodiments, the number of the first load-bearing chains 132 is two, one end of each of the two first load-bearing chains 132 is connected to the oil cylinder 133 , and the other ends of the two first load-bearing chains 132 are respectively connected to the two hooks 131 .
