Obviously, the described embodiments are only a part rather than all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0040] In the present application, the terms "installation", "setting", "providing", "connection", and "coupling" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral structure; it may be a mechanical connection or an electrical connection; it may be directly connected, or indirectly connected through an intermediate medium, or there may be internal communication between two devices, components, or parts. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0041] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, components, or parts (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, components, or parts. Unless otherwise specified, the meaning of "a plurality" is two or more.

[0042] The technical solutions of the present application will be further described below with reference to specific embodiments and the accompanying drawings.

[0043] Please refer to Figure 1 and Figure 2 , an embodiment of the present application provides a handling device 1, including a matching component 11 and a clamping component 12. The matching component 11 is used to be connected to the first side surface 21 of the switch rail 2. The matching component 11 has an inclined surface 1121, and the inclined surface 1121 is inclined relative to the first side surface 21. The distance between the upper end of the inclined surface 1121 and the first side surface 21 is greater than the distance between the lower end of the inclined surface 1121 and the first side surface 21. The clamping component 12 includes a first jaw 121 and a second jaw 122 connected to each other. The first jaw 121 clamps on the inclined surface 1121, and the second jaw 122 is used to clamp the second side surface 22 of the switch rail 2 opposite to the first side surface 21, and the clamping component 12 can provide an upward vertical (as shown by Z in Figure 1 ) acting force.

[0044] Wherein, both the first side surface 21 and the second side surface 22 of the switch rail 2 can extend in the vertical direction. In addition, the matching component 11 can be connected to the switch rail 2 through bolts 31 to improve the connection stability between the matching component 11 and the switch rail 2.

[0045] In this embodiment, the second jaw 122 clamps on the second side surface 22 of the switch rail 2, and the first jaw 121 clamps on the inclined surface 1121 of the matching component 11 to clamp the connecting body of the matching component 11 and the switch rail 2. It can be understood that when the first jaw 121 clamps on the inclined surface 1121, a force perpendicular to the inclined surface 1121 is applied to the inclined surface 1121. Since the distance between the upper end of the inclined surface 1121 and the first side surface 21 is greater than the distance between the lower end of the inclined surface 1121 and the first side surface 21, the force applied by the first jaw 121 to the inclined surface 1121 has a vertically upward component force, and the vertically upward component force can support the matching component 11. Compared with the prior art handling device 1 that directly clamps the first side surface 21 and the second side surface 22 and maintains the stability of the switch rail 2 through the frictional force formed by the first side surface 21 and the second side surface 22, the vertically upward component force of the force applied by the first jaw 121 of the embodiment of the present application to the inclined surface 1121 can support the matching component 11, thereby improving the stability of clamping the connecting body of the matching component 11 and the switch rail 2.

[0046] Please continue to refer to Figure 1 With Figure 2 , in some embodiments, the matching component 11 includes a first matching member 111 and a second matching member 112. The first matching member 111 is attached to and connected to the first side surface 21. The second matching member 112 is connected to the first matching member 111 and is located above the first matching member 111. An inclined surface 1121 is provided on the side of the second matching member 112 facing away from the first side surface 21.

[0047] Among them, the first matching member 111 can be connected to the switch rail 2 by bolts 31, and the second matching member 112 is provided with an inclined surface 1121, so as to ensure the strength of the second matching member 112 and avoid the situation that the second matching member 112 breaks due to stress concentration when the first jaw 121 clamps the inclined surface 1121.

[0048] In some other embodiments, the matching component 11 may only include the second matching member 112.

[0049] Please continue to refer to Figure 1 With Figure 2 , in some more specific embodiments, the matching component 11 further includes a thickening member 113 and a third matching member 114. The thickening member 113 is attached to the first side surface 21 and is located above the second matching member 112. The third matching member 114 is connected to the second matching member 112 and is located above the second matching member 112, and the third matching member 114 is provided on the side of the thickening member 113 facing away from the first side surface 21.

[0050] Among them, the thickness of the third fitting 114 may be equal to the thickness of the first fitting 111 or slightly less than the thickness of the first fitting 111, which is not limited herein, so as to prevent the mass of the third fitting 114 from being too large due to its excessive thickness.

[0051] In addition, the thickening member 113 is disposed between the third fitting 114 and the first side surface 21, such that the distance between the surface of the third fitting 114 facing away from the first side surface 21 and the first side surface 21 is greater than the distance between the surface of the first fitting 111 facing away from the first side surface 21 and the first side surface 21. As a result, when the second fitting 112 is connected between the first fitting 111 and the third fitting 114, an inclined surface 1121 is formed.

[0052] In some other more specific embodiments, the fitting assembly 11 only includes the third fitting 114. The third fitting 114 is attached to the first side surface 21, and the distance between the surface of the third fitting 114 facing away from the first side surface 21 and the first side surface 21 is greater than the distance between the surface of the first fitting 111 facing away from the first side surface 21 and the first side surface 21, so that the second fitting 112 forms an inclined surface 1121.

[0053] In some embodiments, the inclined surface 1121 is provided with a groove (not shown in the figure). The first jaw 121 clamps the inclined surface 1121 and passes through the groove.

[0054] In this embodiment, when the first jaw 121 clamps the inclined surface 1121, such that the vertical upward component of the force exerted by the first jaw 121 on the inclined surface 1121 bears the fitting assembly 11 and the switch rail 2, the first jaw 121 passing through the groove can enhance the stability of the first jaw 121 clamping the second fitting 112, thereby further enhancing the clamping effect of the clamping assembly 12 on the connection body of the fitting assembly 11 and the switch rail 2, and avoiding the situation of detachment when the handling device 1 handles the switch rail 2.

[0055] In some other embodiments, the first jaw 121 may only clamp the inclined surface 1121.

[0056] Please continue to refer to Figure 1 and Figure 2 , in some more specific embodiments, a gap is formed between the second fitting 112 and the first side surface 21. The groove penetrates the second fitting 112. One end of the first jaw 121 away from the second jaw 122 clamps the inclined surface 1121 and extends into the gap through the groove.

[0057] In this embodiment, the first jaw 121 extends into the gap formed between the second fitting 112 and the first side surface 21 through the groove, which can prevent the first jaw 121 from detaching from the second fitting 112 due to the excessive mass of the switch rail 2.

[0058] In some other more specific embodiments, the second engaging member 112 can also be attached to the first side surface 21, and the first clamping jaw 121 is inserted into the groove.

[0059] Please refer to again Figure 1 , in some embodiments, the clamping assembly 12 further includes a support rod 123, and the support rod 123 is connected to the second clamping jaw 122; the handling device 1 further includes a moving assembly 13, and the moving assembly 13 is connected to the support rod 123 and is configured to drive the support rod 123 to move when the first clamping jaw 121 clamps the inclined surface 1121 and the second clamping jaw 122 clamps the second side surface 22.

[0060] Wherein, the axial direction of the support rod 123 can be in the vertical direction, so as to apply a vertically upward acting force to the support rod 123 while the clamping assembly 12 clamps the switch rail 2, so that the clamping assembly 12 clamps the switch rail 2 and lifts the switch rail 2 upward and suspends it, for convenient handling.

[0061] In addition, after the switch rail 2 is suspended, the moving assembly 13 can move substantially in the horizontal direction to drive the support rod 123 to move substantially in the horizontal direction, so as to achieve the purpose of handling the switch rail 2.

[0062] In some other embodiments, after the switch rail 2 is suspended, the support rod 123 can also be held and moved by the staff to handle the switch rail 2.

[0063] Please refer to together Figure 1 With Figure 3 , in some more specific embodiments, the moving assembly 13 includes a moving cylinder 131 and a moving wheel 132. The moving cylinder 131 is disposed at one side of the support rod 123 at intervals and is connected to the support rod 123. The moving wheel 132 is connected to the moving cylinder 131, and the moving wheel 132 is configured to drive the support rod 123 to move through the moving cylinder 131.

[0064] Wherein, the moving cylinder 131 is disposed at one side of the support rod 123 at intervals, so as to avoid interference between the moving cylinder 131 and the clamping assembly 12, etc.

[0065] In this embodiment, after the switch rail 2 is suspended, the moving wheel 132 rolls on the ground or the track, etc., and can drive the moving cylinder 131 to move, so as to drive the support rod 123 to move, so as to achieve the effect of handling the switch rail 2. By moving the switch rail 2 with the moving wheel 132, the handling efficiency can be improved, and at the same time, the load of the staff during the handling process can be reduced.

[0066] In some other more specific embodiments, the staff can also directly move the moving cylinder 131 to handle the switch rail 2.

[0067] Please refer to Figure 3, in some embodiments, a communicating guiding groove (not shown in the figure) and a receiving cavity 1311 are provided in the moving cylinder 131. The guiding groove is located between the receiving cavity 1311 and the support rod 123. The moving assembly 13 further includes a guiding rod 133 and a connecting member 134. The guiding rod 133 is disposed in the receiving cavity 1311, and the axial direction of the guiding rod 133 is parallel to the axial direction of the support rod 123. The connecting member 134 is inserted through the guiding groove, and one end of the connecting member 134 is connected to the support rod 123, and the other end is connected to the guiding rod 133 and can move along the axial direction of the guiding rod 133 to drive the support rod 123 to move relative to the axial direction of the guiding rod 133.

[0068] Wherein, the axial direction of the guiding rod 133 is in the vertical direction.

[0069] In this embodiment, the support rod 123 is connected to the guiding rod 133 through the connecting member 134, and the connecting member 134 can move along the axial direction of the guiding rod 133 on the guiding rod 133, so that the support member can be driven to move vertically upward to suspend the switch rail 2.

[0070] The working principle of this embodiment is as follows: First, the mating assembly 11 is installed on the first side surface 21 of the switch rail 2 to be carried, and then the moving assembly 13 is placed on one side of the switch rail 2 to be carried, and the clamping assembly 12 and the support rod 123 are located above the switch rail 2 to be carried. After the carrying device 1 is in place, the connecting member 134 moves downward along the guiding rod 133 to drive the support rod 123 to move downward, so that the clamping assembly 12 can clamp the connecting body of the mating assembly 11 and the switch rail 2. After clamping, the connecting member 134 moves upward along the guiding rod 133 to drive the clamping assembly 12 to move upward through the support rod 123, so that the switch rail 2 is suspended, and the moving wheels 132 move to carry the switch rail 2.

[0071] In some other embodiments, the end of the connecting member 134 away from the support rod 123 can be disposed in the guiding groove and can move in the guiding groove.

[0072] In some more specific embodiments, the guiding rod 133 is rotatably disposed in the receiving cavity 1311. The guiding rod 133 is provided with an external thread, and the end of the connecting member 134 connected to the guiding rod 133 is provided with an internal thread. The connecting member 134 and the guiding rod 133 are connected by threads.

[0073] In this embodiment, the guiding rod 133 and the connecting member 134 are connected by threads, so that the connecting member 134 can move along the axial direction of the guiding rod 133 by rotating the guiding rod 133.

[0074] Exemplarily, one end of the guiding rod 133 protrudes from the moving cylinder 131, and a handle is connected to the end protruding from the moving cylinder 131. The staff can rotate the guiding rod 133 by rotating the handle.

[0075] In some other more specific embodiments, the connecting member 134 and the guide rod 133 may also be connected by a rack and pinion.

[0077] In this embodiment, the support rod 123 and the connecting member 134 are connected by a thread, so that the connecting member 134 can rotate around the axial direction of the support rod 123, that is, the connecting member 134 can move along the axial direction of the support rod 123. The connecting member 134 can move along the axial direction of the support rod 123, that is, the relative position between the connecting member 134 and the support rod 123 can be adjusted, so that the distance between the connecting member 134 and the clamping assembly 12 in the axial direction of the support rod 123 can be adjusted.

[0078] In some other more specific embodiments, the support rod 123 may also be provided with a rail, and the connecting member 134 is arranged on the rail and can move along the rail.
