DETAILED DESCRIPTION

[0026] In the following, exemplary embodiments of the present application will be described with reference to the drawings. In the description, not all the features of the actual embodiments are described for the sake of clarity and conciseness. It should be appreciated, however, that many implementation-specific decisions can have to be made in order to develop any such actual embodiment, to achieve the developer's specific goals, such as compliance with system- and business-related constraints, which will vary from one implementation to another. It should also be appreciated that such a development effort might be very complex and time-consuming, but would nevertheless be a routine undertaking for those of ordinary skill in the art having the benefit of this disclosure.

[0027] It should also be noted that, in the description of the present application, only the device structures and / or processing steps that are closely related to the solution according to the present application are shown in the drawings, and other details that are not closely related to the present application are omitted.

[0028] It should be noted that the technical or scientific terms used in the present application should be understood as having their ordinary meaning to a person of ordinary skill in the art, unless otherwise defined.

[0029] In the description of the embodiments of the present application, the meaning of "a plurality of" is at least two, for example, two, three, etc., unless otherwise explicitly and specifically limited.

[0030] At present, in order to protect the railway switch, the relevant technology sets a protective cover to cover the part where the rod is connected to the railway switch, so as to prevent rain, snow or water dripping from vehicles from entering the shell of the railway switch and causing adverse effects on the railway switch.

[0031] The inventors of this application have discovered that such protection cannot guarantee that the railway switch machine body will not be damaged. Because some vehicles have long mileages, such as vehicles traveling from southern China to northern China, there is water on the vehicle body in the southern region (for example, due to rainy weather, etc.). Once the temperature drops in the north, the water freezes and forms icicles or ice blocks. During the driving process, the icicles or ice blocks will fall at a high speed and hit the railway switch machine, damaging it.

[0032] In response to the above-mentioned problems, an embodiment of the present application provides a protective device suitable for a railway switch, which is used to prevent ice or icicles falling from a vehicle from damaging the railway switch.

[0033] See also Figure 1 , Figure 1 The schematic diagram shows a structure in which a railway switch machine is connected to two sleepers under a rail through two switch machine mounting members. The railway switch machine 10 is connected to two sleepers 30 under a rail through two switch machine mounting members 20 .

[0034] See also Figures 2 to 5 , Figures 2 to 5 Schematic diagrams of the structure of the protective device provided by the embodiment of the present application installed on both sides of a railway switch machine, viewed from different angles, are shown. The protective device provided by the embodiment of the present application may include two protective members 40. The two protective members 40 are arranged on opposite sides of the railway switch machine 10 along the extension direction of the rails (i.e., the arrangement direction of the sleepers 30), and each protective member 40 is connected to a switch machine mounting member 20.

[0035] Each guard member 40 includes a guard body 41 and a mounting portion 42 connected to the guard body 41. The mounting portion 42 is used to connect to a corresponding switch machine mounting member 20 via a fastener 43. The side of the guard body 41 facing away from the railway switch machine 10 forms a guard surface 411 to reduce the impact force from objects extending in the direction of the rails.

[0036] The protection device provided by the embodiment of the present application is provided with two protection pieces 40 on both sides of the railway switch machine 10 along the extension direction of the railway, so that when a vehicle passes by, the ice and snow foreign matters and other articles falling from the vehicle will impact one of the protection pieces 40, which is conducive to reducing the risk of the railway switch machine 10 being damaged by the ice and snow foreign matters and other articles falling from the vehicle. Since the protection piece 40 is connected with the switch machine mounting 20, the installation of the protection piece 40 is stable, and the cost of installing the protection piece 40 is reduced. The embodiment of the present application further forms a protection surface 411 on the side of the protection body 41 opposite to the railway switch machine 10, so as to reduce the impact force of the objects from the extension direction of the railway, which is conducive to reducing the risk of the protection piece 40 being damaged by the ice and snow foreign matters and other articles falling from the vehicle.

[0037] Referring to Figure 2 In some embodiments, the length of the two protection pieces 40 along the extension direction of the sleeper 30 is substantially the same as the length of the railway switch machine 10 along the extension direction of the sleeper 30, so that the protection piece 40 can provide more comprehensive protection for the articles flying along the direction of the vehicle.

[0038] In some embodiments, the protection surface 411 is a slope. The end of the slope close to the railway switch machine 10 is higher than the end of the slope away from the railway switch machine 10. That is, the slope extends upwardly and inclines towards the direction of the railway switch machine 10. In this way, the impact force of the objects from the extension direction of the railway is deflected and dispersed, thereby reducing the risk of the protection piece 40 and the railway switch machine 10 being damaged.

[0039] As Figures 7 to 10 shown, Figure 7 and Figure 8 show the schematic views of the protection piece facing the hinge side of the shell of the railway switch machine from different angles according to an embodiment of the present application; Figure 9 and Figure 10 show the schematic views of the protection piece facing the locking side of the shell of the railway switch machine from different angles according to an embodiment of the present application. In some embodiments, the side of the protection body 41 facing the railway switch machine 10 forms an abutting surface 412, which is used to abut against the shell of the railway switch machine 10 to support the shell of the railway switch machine 10 along the extension direction of the railway. In such embodiments, when the shell of the railway switch machine 10 is subjected to an impact force, the abutting surface 412 can support the railway switch machine 10, so as to reduce the impact borne by the shell of the railway switch machine 10, thereby reducing the risk of the railway switch machine 10 being damaged.

[0040] In some embodiments, the surface of the mounting portion 42 facing the railway switch machine 10 can also abut against the housing of the railway switch machine 10 to support the housing of the railway switch machine 10 together with the abutment surface 412 along the extension direction of the rail, thereby reducing the impact on the housing of the railway switch machine 10 and reducing the risk of damage to the railway switch machine 10.

[0041] Referring to Figures 3 to 5 In some embodiments, the housing of the railway switch machine 10 includes a housing body 11 having an upper opening and a housing cover 12 having a lower opening, and the housing cover 12 is connected to the housing body 11 to open or close the housing body 11. The abutment surface 412 is used to abut against the housing body 11. In this way, the abutment surface 412 supports the railway switch machine 10 while not affecting the opening and closing of the housing body 11, thereby reducing the risk of damage to the railway switch machine 10 and not affecting the normal use of the railway switch machine 10.

[0042] Referring to Figure 1 and Figure 5 In some embodiments, the housing cover 12 and the housing body 11 are hinged on one side facing one switch mounting member 20 through a hinge portion 13 and are locked or unlocked on the other side facing the other switch mounting member 20 through a locking portion 14. In other words, the housing cover 12 and the housing body 11 are hinged through the hinge portion 13, and the housing cover 12 and the housing body 11 are locked or unlocked through the locking portion 14, and the hinge portion 13 and the locking portion 14 are respectively arranged on both sides of the railway switch machine 10 along the extension direction of the rail.

[0043] The surface of the protective body 41 facing the housing cover 12 is recessed away from the housing cover 12 to form a clearance space 401. The abutment surface 412 is used to abut against the housing body 11, and the clearance space 401 is formed above the abutment surface 412. The present embodiment ensures the normal function of the housing body 11 and the housing cover 12 by forming the clearance space 401 in both protective members 40. Specifically, by forming the clearance space 401 in both protective members 40, the locking portion 14 can be operated to lock or unlock the housing cover 12 and the housing body 11, and the housing cover 12 can be moved to the maximum open position relative to the housing body 11.

[0044] Referring to Figure 1 Since the housing cover 12 needs to rotate around the hinge portion 13 during locking or unlocking, in some embodiments, the size of the clearance space 401 formed by the protective member 40 facing the hinge portion 13 along the extension direction of the rail is greater than the size of the clearance space 401 formed by the protective member 40 facing the locking portion 14 along the extension direction of the rail, thereby facilitating the housing cover 12 to move to the maximum open position relative to the housing body 11.

[0045] In some embodiments, the size of the guard 40 facing the hinge part 13 along the extension direction of the rail is larger than the size of the switch machine mounting part 20, and the size of the guard 40 facing the locking part 14 along the extension direction of the rail is smaller than the size of the switch machine mounting part 20.

[0046] In order to ensure the installation stability of the guard 40, the size of the guard 40 facing the locking part 14 along the extension direction of the rail is smaller than the size of the switch machine mounting part 20. Since the size of the space 401 formed by the guard 40 facing the hinge part 13 along the extension direction of the rail is relatively large, in order to ensure that the included angle between the guard surface 411 and the horizontal plane is within a relatively appropriate range, the size of the guard 40 facing the hinge part 13 along the extension direction of the rail is relatively large, which is larger than the size of the switch machine mounting part 20, which may cause the installation of the guard 40 facing the hinge part 13 to be not stable enough.

[0047] In order to solve the above problems, referring to Figure 1 and Figure 4 In some embodiments, the side of the switch machine mounting part 20 away from the railway switch machine 10 forms a reinforcing rib 21 to reinforce the mechanical strength of the switch machine mounting part 20. Referring to Figure 4 and Figure 5 The bottom of the guard body 41 of the guard 40 facing the hinge part 13 forms a first space-allowing groove 413; when the guard body 41 is installed on the switch machine mounting part 20 through the mounting part 42, the reinforcing rib 21 is located in the first space-allowing groove 413. Since the guard body 41 forms the first space-allowing groove 413 and the reinforcing rib 21 is located in the first space-allowing groove 413, the installation of the guard 40 facing the hinge part 13 is realized, and the installation stability of the guard 40 is also improved.

[0048] A gap is formed between the guard body 41 of the guard 40 facing the locking part 14 and the reinforcing rib 21 of the corresponding switch machine mounting part 20. Since the guard 40 may be damaged due to the impact force after long-term use, it needs to be repaired or replaced regularly. The gap between the guard body 41 and the reinforcing rib 21 can facilitate the installation and disassembly of the guard 40, thereby improving the maintenance efficiency.

[0049] Referring to Figure 8 In some embodiments, the abutting surface 412 of the guard 40 facing the hinge part 13 is recessed in the direction away from the shell body 11 to form a third space-allowing groove 404. The third space-allowing groove 404 provides a space for the hinge part 13, which is beneficial to the opening or closing of the shell cover body 12 relative to the shell body 11.

[0050] Referring to Figure 9 andFigure 10 In some embodiments, the space 401 of the shield 40 on the side facing the locking portion 14 is recessed in a direction away from the shell body 11 to form a second recessed slot 403, which provides a space for the locking portion 14 and facilitates locking or unlocking of the shell cover 12 and the shell body 11.

[0051] Referring to Figures 2 to 4 In some embodiments, the shield body 41 forms a channel 402 extending along the extension direction of the rail, for the cable of the railway switch machine 10 to pass through. In such embodiments, the installation of the shield 40 does not change the original cable arrangement of the railway switch machine 10, and can also avoid the cable joints being exposed to the external environment, reducing the risk of damage to the cable joints.

[0052] In some embodiments, the mounting portion 42 is connected to the railway switch machine 10 and the corresponding switch mounting member 20 by the fastener at the same time, so that the connection of the shield 40, the railway switch machine 10 and the switch mounting member 20 is improved, further ensuring the stability of the installation of the shield 40 and reducing the cost of installing the shield 40.

[0053] Referring to Figure 1 In some embodiments, the side of the railway switch machine 10 facing the switch mounting member 20 forms a mounting lug 15 with a mounting hole.

[0054] Referring to Figure 5 , Figures 7 to 10 The mounting portion 42 includes a first mounting sub-portion 421 and a second mounting sub-portion 422 connected to the first mounting sub-portion 421. The first mounting sub-portion 421 forms a recessed mounting slot 4211 at a position corresponding to the mounting lug 15, and a first mounting hole 4212 above the recessed mounting slot 4211, so that the first mounting sub-portion 421 and the mounting lug 15 are connected to the switch mounting member 20 by the same fastener 43, realizing the connection of the shield 40, the railway switch machine 10 and the switch mounting member 20, thereby improving the stability of the three. In addition, the second mounting sub-portion 422 forms a second mounting hole 4221 at a position corresponding to the first mounting hole 4212 away from the mounting lug 15, so as to be connected to the switch mounting member 20 by another fastener 43. In this way, the assembly and disassembly between the shield 40 and the switch mounting member 20 are facilitated, and the stability of the installation of the shield 40 on the switch mounting member 20 is improved.

[0055] In some embodiments, referring to Figure 5The top surface 414 of the protection body 41 is flush with the top surface 414 of the shell cover body 12. The top surface 414 of the protection body 41 is flush with the top surface 414 of the shell cover body 12, that is, the height of the protection member 40 is the same as the height of the railway switch machine 10, so that the protection member 40 can effectively shield the shell of the railway switch machine 10, preventing objects from the direction of the rail extension from directly hitting the railway switch machine 10, thereby reducing the risk of damage to the railway switch machine 10, while not affecting the safety of the vehicle.

[0056] Referring to Figure 6 The bottom surface 4011 of the accommodation space 401 is flush with the top surface 414 of the shell body 11. The bottom surface 4011 of the accommodation space 401 is arranged to be flush with the top surface 414 of the shell body 11, which is conducive to the rotation of the shell cover body 12 in the accommodation space 401, and also provides better support for the shell body 11.

[0057] For the embodiments of the present application, it should also be noted that the embodiments and features in the embodiments of the present application can be combined with each other to obtain new embodiments without conflict.

[0058] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto, and the protection scope of the present application shall be subject to the protection scope of the claims.
