Technical Field

[0001] This utility model belongs to the field of dust prevention technology for subway vehicle bogies, specifically a dust cover for subway vehicle bogies. Background Technology

[0002] A subway car bogie dust cover is a device specifically designed to protect subway car bogies from dust, dirt, and other external environmental factors. Its main function is to prevent dust and impurities from entering the bogie's interior, thereby protecting the bogie's mechanical components from damage and extending its service life.

[0003] Currently, existing dust covers for subway car bogies are generally used in a completely sealed manner. This can lead to excessively high internal temperatures after prolonged use, which can affect the bogie's steering performance and pose a risk of breakage due to overheating, resulting in serious safety hazards. Therefore, it is necessary to design a new type of dust cover for subway car bogies. Summary of the Invention

[0004] To address the aforementioned issues, and to resolve the problem that existing subway car bogie dust covers, which are generally used in a completely sealed manner, often lead to excessively high internal temperatures after prolonged use, affecting the bogie's steering performance and posing a risk of breakage due to overheating—a serious safety hazard—this invention provides a subway car bogie dust cover that effectively provides a surround-seal dustproof function for the subway car bogie. It also allows for timely cooling of the bogie when environmental conditions permit, and the seal can be quickly restored after cooling. Furthermore, the first and second flow holes filter the airflow, ensuring the dustproof effect of the subway car bogie dust cover and preventing overheating of the subway car bogie, thus improving the performance of the subway car bogie.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dust cover for a subway car bogie, comprising a protective component, wherein a fixed end of a linear drive component is provided on the outer wall of the protective component, and a sealing component is detachably connected to the movable end of the linear drive component. The protective component is used to connect to the subway car bogie and perform protective operations on the subway car bogie. The linear drive component is used to drive the sealing component to move linearly, thereby allowing the sealing component to open or close the ventilation component of the protective component, thus completing the conversion between dust protection and ventilation of the dust cover.

[0006] The aforementioned dust cover for a subway car bogie includes a housing. A protective groove is formed on one side of the outer wall of the housing, and a recess is formed on the other side of the outer wall of the housing. A first flow hole is formed on the inner side wall of the recess. A side groove is formed on the outer wall of the bottom surface of the housing, and a second flow hole is formed on the inner side wall of the side groove. A limiting groove and a slot are also formed on the outer surface of the housing, wherein the slot can laterally cut off the second flow hole.

[0007] A connecting plate is provided on the outer wall of the opening end of the protective groove, and a connecting hole is provided on the outer wall of the connecting plate.

[0008] The aforementioned dust cover for a subway car bogie includes a linear drive assembly comprising an electric cylinder, which is detachably connected to the upper surface of the housing, and the lower end of a pneumatic telescopic rod is slidably connected to the inner wall of the electric cylinder.

[0009] The aforementioned dust cover for a subway vehicle bogie includes a sealing assembly comprising an end plate, the end plate being detachably connected to the upper end of a pneumatic telescopic rod, a limiting rod being provided on the outer wall of the end plate facing the housing, and the outer wall of the limiting rod being slidably connected to the inner wall of the limiting groove, and a sealing ring being provided on the outer wall of the end plate facing the housing, and the outer wall of the sealing ring being fitted with the inner wall of the groove.

[0010] The aforementioned dust cover for a subway car bogie includes a sealing assembly that further includes an insert plate. The insert plate is disposed on the outer wall of the end plate facing the housing, and the outer wall of the insert plate fits into the inner wall of the slot.

[0011] The aforementioned dust cover for a subway vehicle bogie has four limiting rods and four limiting grooves, and the four limiting grooves are evenly distributed on the outer surface of the housing.

[0012] The aforementioned dust cover for a subway vehicle bogie has multiple first flow holes and multiple second flow holes, with the multiple first flow holes evenly distributed on the inner sidewall of the groove, and the multiple second flow holes evenly distributed on the inner sidewall of the side groove.

[0013] The aforementioned dust cover for a subway car bogie has multiple connecting holes, all of which are used to connect with external fasteners to the subway car bogie.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) First, move the shell and fit the connecting plate with the support of the subway car bogie. Then, use external fasteners along the connecting holes to make the connecting plate and the support of the subway car bogie detachable. This allows the shell and the support of the subway car bogie to be detachable, so that the protective groove can perform dust protection on the subway car bogie. This effectively realizes that the dust cover of the subway car bogie has the function of providing a surrounding seal for dust protection. The dust cover and the subway car bogie are easy to install and remove. The dust cover of the subway car bogie has a simple structure and strong practicality.

[0016] (2) The pneumatic telescopic rod is driven to extend and slide by the operation of the electric cylinder, thereby driving the end plate to move linearly. This causes the sealing ring to disengage from the groove and exposes the first flow hole. At the same time, the second flow hole is exposed as the insert plate slides along the slot. This allows the external airflow to flow into the protective groove through the first flow hole and then out through the second flow hole, thus cooling the subway car bogie inside the groove in time. The linear sliding action of the limit rod along the limit groove ensures the stability of the linear movement of the end plate. This effectively realizes that the subway car bogie dust cover has the function of timely cooling and temperature reduction of the subway car bogie when the environment permits. After cooling and temperature reduction, it can also quickly reset the seal. At the same time, the airflow can be filtered through the first and second flow holes. This not only ensures the dustproof effect of the subway car bogie dust cover, but also avoids the subway car bogie from overheating, improves the performance of the subway car bogie, and eliminates the existing safety hazards. The subway car bogie dust cover has a simple structure and strong practicality. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model. Example

[0025] Depend on Figures 1-5 This invention discloses a dust cover for a subway car bogie, comprising a protective component 1. The outer wall of the protective component 1 is provided with a fixed end of a linear drive component 2, and the movable end of the linear drive component 2 is detachably connected to a sealing component 3. The protective component 1 is used to connect to the subway car bogie and perform protective operations on the subway car bogie. The linear drive component 2 is used to drive the sealing component 3 to move linearly, thereby allowing the sealing component 3 to open or close the ventilation component of the protective component 1, thus completing the conversion between dust protection and ventilation of the dust cover. This invention enables the subway car bogie dust cover to have the function of providing a surrounding seal for dust protection, and the assembly and disassembly of the dust cover from the subway car bogie is relatively convenient.

[0026] Specifically, the protective component 1 includes a housing 101. A protective groove 1010 is formed on one side of the outer wall of the housing 101, and a recess 104 is formed on the other side of the outer wall of the housing 101. A first flow hole 105 is formed on the inner side wall of the recess 104. A side groove 106 is formed on the outer wall of the bottom surface of the housing 101, and a second flow hole 107 is formed on the inner side wall of the side groove 106. A limiting groove 109 and a slot 108 are also formed on the outer surface of the housing 101, wherein the slot 108 can laterally cut off the second flow hole 107. The outer wall of the opening end of the protective groove 1010 is provided with a connecting plate 102, and the outer wall of the connecting plate 102 is provided with a connecting hole 103. By moving the housing 101 and fitting the connecting plate 102 with the subway car bogie support, and then cooperating with the external fastener along the connecting hole 103, the connecting plate 102 and the subway car bogie support can be detachably connected. In addition, the housing 101 and the subway car bogie support can be detachably connected. In this way, the protective groove 1010 can perform dust prevention work on the subway car bogie.

[0027] Specifically, the linear drive assembly 2 includes an electric cylinder 201, which is detachably connected to the upper surface of the housing 101. The lower end of a pneumatic telescopic rod 202 is slidably connected to the inner wall of the electric cylinder 201. The operation of the electric cylinder 201 drives the pneumatic telescopic rod 202 to extend and slide, thereby driving the end plate 301 to move linearly, which in turn drives the sealing ring 303 to disengage from the groove 104 and exposes the first flow hole 105.

[0028] Specifically, the sealing assembly 3 includes an end plate 301, which is detachably connected to the upper end of the pneumatic telescopic rod 202. A limiting rod 302 is provided on the outer wall of the end plate 301 facing the housing 101, and the outer wall of the limiting rod 302 is slidably connected to the inner wall of the limiting groove 109. A sealing ring 303 is also provided on the outer wall of the end plate 301 facing the housing 101, and the outer wall of the sealing ring 303 fits into the inner wall of the groove 104. The sealing assembly 3 enables the subway vehicle bogie dust cover to cool down the subway vehicle bogie in a timely manner when the environment permits, and can quickly reset the seal after cooling down.

[0029] Specifically, the sealing assembly 3 further includes an insert plate 304, which is disposed on the outer wall of the end plate 301 on the side facing the housing 101, and the outer wall of the insert plate 304 fits into the inner wall of the slot 108. The second flow hole 107 can be exposed by the sliding action of the insert plate 304 along the slot 108.

[0030] Specifically, there are four limiting rods 302 and four limiting grooves 109, and the four limiting grooves 109 are evenly distributed on the outer surface of the housing 101. The stability of the linear movement of the end plate 301 is ensured by the linear sliding action of the limiting rods 302 along the limiting grooves 109.

[0031] Specifically, there are multiple first flow holes 105 and multiple second flow holes 107. The multiple first flow holes 105 are evenly distributed on the inner sidewall of the groove 104, and the multiple second flow holes 107 are evenly distributed on the inner sidewall of the side groove 106. The multiple first flow holes 105 and multiple second flow holes 107 allow external airflow to flow into the protective groove 1010 through the first flow holes 105 and then out through the second flow holes 107, thereby enabling timely cooling of the subway vehicle bogie inside the groove 104.

[0032] Specifically, there are multiple connection holes 103, and all of the multiple connection holes 103 are used to connect with external fasteners and the metro vehicle bogie. The multiple connection holes 103 make the detachable connection between the housing 101 and the metro bogie support more secure.

[0033] In use, firstly, the housing 101 is moved and the connecting plate 102 is fitted to the subway car bogie support. Then, external fasteners are used along the connecting hole 103 to detachably connect the connecting plate 102 to the subway car bogie support. This allows the housing 101 to be detachably connected to the subway car bogie support, enabling the protective groove 1010 to perform dust protection on the subway car bogie. This effectively realizes the function of the subway car bogie dust cover in providing a surrounding seal against dust, and the assembly and disassembly of the dust cover to the subway car bogie is relatively convenient. Next, the electric cylinder 201 drives the pneumatic telescopic rod 202 to extend and slide, thereby driving the end plate 301 to move linearly. This causes the sealing ring 303 to disengage from the groove 104, exposing the first flow hole 105. At the same time, the insertion plate 304 moves along the slot 101. The sliding action of 08 exposes the second flow hole 107, allowing external airflow to flow into the protective groove 1010 through the first flow hole 105 and then out through the second flow hole 107, thus providing timely cooling for the metro vehicle bogie inside the groove 104. Meanwhile, the linear sliding action of the limit rod 302 along the limit groove 109 ensures the stability of the linear movement of the end plate 301. This effectively enables the metro vehicle bogie dust cover to provide timely cooling of the metro vehicle bogie when environmental conditions permit, and it can quickly reset and seal after cooling. Furthermore, the first and second flow holes 105 and 107 can filter the airflow, ensuring not only the dustproof effect of the metro vehicle bogie dust cover but also preventing the metro vehicle bogie from overheating, improving the performance of the metro vehicle bogie, and eliminating potential safety hazards.
