DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0031] Combine the following Figures 1 to 4 , describing an embodiment of the utility model.

[0032] In the related art, when observing the position of the brake rail of a railway parking device, on-site staff are required to be located on one side of the railway parking device and observe from the top of the railway parking device downwards in order to see the position information of the brake rail. Since the train usually stops on the railway parking device when the railway parking device is in working condition, the on-site staff are blocked by the train and cannot observe the brake rail conveniently and quickly, and therefore cannot effectively judge the braking status of the railway parking device.

[0033] According to an embodiment of the utility model, on the one hand, an easily identifiable parking anti-slip position display device is provided, which is used to display the braking state of the parking device. The parking device includes a main body 3 and a travel switch assembly 4. The travel switch assembly 4 can be laterally moved on the main body 3. The position display device includes: a reference component 1 and a position display component 2. The reference component 1 is arranged on the main body 3. The reference component 1 has a reference structure 101 fixedly arranged relative to the main body 3. The position display component 2 is arranged on the travel switch assembly 4 and cooperates with the reference structure 101. The position display component 2 has a braking state in which it moves forward with the travel switch assembly 4 and is in a first relative position relative to the reference structure 101. The position display component 2 also has a relief state in which it moves reversely with the travel switch assembly 4 and is in a second relative position relative to the reference structure 101.

[0034] In the position display device of the present embodiment, a reference component 1 is set on the main body 3 and a reference component 1 is set on the travel switch assembly 4. Since the travel switch assembly 4 is usually located at one end of the middle part of the main body 3 and is telescopically movable along the extension direction of the railway, the position display component 2 can be telescopically movable along with the state change of the travel switch assembly 4. When the position of the position display component 2 moves, the relative position with the reference structure 101 of the reference component 1 will change. At the same time, the position display device is not blocked by the train. Therefore, on-site staff can directly observe the relative position state of the position display component 2 and the reference structure 101 at this time, and can quickly and effectively judge the working state of the parking device, thereby effectively solving the problem of time-consuming and labor-intensive state judgment method of existing railway parking devices.

[0035] It should be noted that horizontal refers to Figure 1 The "lateral" direction indicated by the middle arrow, the forward movement and the reverse movement respectively refer to movement in two opposite directions along the lateral direction, and the specific direction of one of the movement directions is not strictly limited, as long as the movement directions are opposite.

[0036] It can be understood that, as an alternative implementation, the reference component 1 may not be provided separately, and the structure near the main body 3 of the parking device may be directly used as the reference component 1, which can only clearly reflect the position change of the position indicating component 2.

[0037] Specifically, there is no limitation on the specific structure of the position indicating component 2 , which may be a columnar, block-shaped, spherical or frame structure, as long as it can move together with the travel switch assembly 4 .

[0038] Furthermore, there is no limitation on the specific form of the reference component 1. The reference component 1 may have a through hole for the position display component 2 to pass through, and a status display window is provided on the side wall of the through hole. The position of the segments of the position display component 2 appearing in the status display window is different to reflect the position information of the position display component 2. The reference component 1 may also form a reference surface on one end face along the moving direction of the position display component 2, and the position information of the position display component 2 is reflected by the length of the position display component 2 exceeding the reference surface, and so on. The methods can be flexibly selected according to the needs.

[0039] In this embodiment, the reference component 1 is located on one side of the position indicating component 2. The reference component 1 forms a reference structure 101 along the moving direction of the position indicating component 2 and on the end face away from the travel switch assembly 4. This form of reference structure 101 is simple in structure and easy to process. At the same time, when the relative position of the end face and the position indicating component 2 changes, it is easier to identify.

[0040] Specifically, there is no limitation on the matching mode between the reference component 1 and the position display component 2. The reference component 1 can be spaced apart from the position display component 2, and the position display component 2 can also be movably arranged on the reference component 1, as long as the relative position change between the end face corresponding to the reference component 1 and the position display component 2 can be easily observed.

[0041] In this embodiment, the position indicating component 2 includes a first mating segment 201 and a second mating segment 202 which are connected in sequence in the direction close to the travel switch assembly 4. When the position indicating component 2 is in a braking state, the second mating segment 202 is located on the side of the reference structure 101 close to the travel switch assembly 4. When the position indicating component 2 is in a relief state, at least a portion of the second mating segment 202 is located on the side of the reference structure 101 away from the travel switch assembly 4. Different segments mating with the reference structure 101 represent that the position indicating component 2 is in different positions, and the method is simple and reliable.

[0042] Specifically, Figure 1 As shown, in order to more easily distinguish the first mating segment 201 and the second mating segment 202, the first mating segment 201 and the second mating segment 202 need to adopt distinctive appearance features, wherein the manner in which the first mating segment 201 and the second mating segment 202 have different appearance features is not strictly limited, and may be by using different types of materials, or by using different types of colors, or by providing different types of coatings on the outer wall, etc., as long as it is convenient for on-site staff to distinguish the first mating segment 201 and the second mating segment 202.

[0043] In this embodiment, the position indicating assembly 2 includes a position indicating rod and a connecting piece 203. The position indicating rod forms a first mating section 201 and a second mating section 202. The position indicating rod is detachably connected to the travel switch assembly 4 via the connecting piece 203. The connecting piece 203 can effectively improve the flexibility of the position of the position indicating rod.

[0044] Specifically, Figure 1 As shown, the end of the connecting member 203 away from the position indicating rod forms an arc-shaped extending connecting structure, and the connecting structure is provided with through holes for fastening components such as bolts and screws to pass through. This type of connecting member 203 is more stable and reliable when connected to the travel switch assembly 4.

[0045] In this embodiment, one end of the connecting piece 203 forms a connecting end 2031, and the second mating section 202 has a mating hole 2021 that cooperates with the connecting end 2031. The outer wall of the connecting end 2031 is provided with an external thread, and the inner wall of the mating hole 2021 is provided with an internal thread. The connection method is simple and reliable. The assembly can be completed by directly tightening the indicating rod on the connecting end 2031 of the connecting piece 203. The disassembly and assembly are convenient and quick.

[0046] In this embodiment, the position indicating rod is a nylon rod, which is easy to manufacture and not prone to corrosion and oxidation. It is light in weight and more durable.

[0047] It can be understood that, as an alternative implementation, the position display rod can also be a metal rod, a wooden rod or other types of plastic rods, which can be flexibly selected according to needs.

[0048] Preferably, in order to facilitate the separate display of the first mating section 201 and the second mating section 202 of the rod, the nylon rods of the first mating section 201 and the second mating section 202 have different colors. For example, the first mating section 201 can be red and the second mating section 202 can be green, with a large contrast and easy to distinguish.

[0049] In this embodiment, the reference component 1 includes a bearing seat 102 and a guide member 103. The bearing seat 102 is connected to the main body 3. The end face of the bearing seat 102 forms a reference structure 101. The guide member 103 is arranged on the bearing seat 102. The guide member 103 extends along the moving direction of the position display component 2. The position display component 2 slides with the guide member 103 through the matching member 204. The guide member 103 can further support the position display component 2 and can guide the movement of the position display component 2, thereby effectively improving the movement reliability of the position display component 2.

[0050] Among them, there is no limitation on the specific types and structures of the guide member 103 and the matching member 204. The guide member 103 can be a guide rod, a guide groove, a guide rail, etc. The matching member 204 corresponds to the form of the guide member 103. The guide member 103 and the matching member 204 can just play a guiding role.

[0051] In this embodiment, the guide member 103 is a guide rod, one end of the matching member 204 is fixedly connected to the position indicating assembly 2, and the other end is sleeved on the guide rod. The guiding form is simple and reliable, and is easy to manufacture and disassemble.

[0052] In this embodiment, the support base 102 is provided with a receiving groove 1021 for the position display component 2 to pass through. The receiving groove 1021 can effectively protect the position display component 2 and prevent nearby components from interfering with the position display component 2.

[0053] Specifically, Figure 1 and Figure 2 As shown, the bearing seat 102 forms end covers at both ends along the extension direction of the guide member 103, and the end surface of the end cover away from the main body 3 forms a reference structure 101. The end cover away from the main body 3 is provided with a receiving groove 1021 for the position indicating rod to pass through, and the end cover close to the main body 3 is provided with a receiving groove 1021 for the connecting member 203 to pass through.

[0054] In this embodiment, if Figure 2 and Figure 3As shown, the position display device further includes a cover body 7 for accommodating the reference component 1 and the position display component 2 .

[0055] In addition, if Figure 2 and Figure 3 As shown, the cover body 7 is provided with a through hole for the position indicating rod to move through. At this time, the outer end surface of the cover body 7 near the through hole is the reference structure 101. By observing the sections where the position indicating rod passes through the through hole of the cover body 7, the position status of the position indicating rod can be respectively determined.
