Description

Technical Field

[0001] This utility model relates to the field of rail train technology, specifically a train skirt locking device. Background Technology

[0002] In the field of rail vehicle technology, the fixing device for train skirts plays a crucial role. Currently, existing train skirt locking devices have some significant drawbacks. With ordinary one-way positioning methods, if bolts come loose during train operation, it is highly susceptible to causing the train skirts to warp, affecting the normal operation and safety of the train.

[0003] Based on this, a train skirt locking device is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0004] The purpose of this utility model is to provide a train skirt locking device to solve the problem that if the bolts come loose in the ordinary one-way positioning method in the background art, the train skirt will easily warp, affecting the normal operation and safety of the train.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A train skirt locking device includes a housing, a mounting plate, a fixing cylinder, and a pin cylinder. The housing and the mounting plate are both disposed on the side wall of the train. The pin cylinder is disposed inside the train skirt. The mounting plate is connected to the train skirt by bolts. The fixing cylinder is fixedly connected to the inner side wall of the housing. The pin is slidably connected to the inner side wall of the fixing cylinder. The pin is slidably connected to the inner side wall of the pin cylinder.

[0007] Based on the above technical solutions, this utility model also provides the following optional technical solutions:

[0008] In one alternative: the side wall of the fixed cylinder is provided with a U-shaped groove, and the side wall of the pin is fixedly connected with a pull block, which is slidably connected to the inner side wall of the U-shaped groove.

[0009] In one alternative: a rotating plate is connected to the pin side via a bearing, and a spring is fixedly connected between the rotating plate and the inner wall of the fixed cylinder.

[0010] In one alternative: both the fixing cylinder and the pin sidewall are provided with locking bolt holes, and the locking bolts are threadedly connected to the pin.

[0011] In one alternative: the housing is bolted to a cover.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model changes the traditional unidirectional positioning method by limiting and fixing the train skirt along the X-axis and Y-axis, effectively avoiding the situation where the skirt edge warps due to bolt detachment during train operation, greatly improving the fixing effect of the train skirt, and ensuring the safety and stability of train operation.

[0014] 2. The pin structure of this utility model allows for pre-positioning along the X-axis before bolt positioning along the Y-axis. Workers can quickly pre-fix the train skirt by simply pulling the pin. This design reduces the time spent manually lifting the train skirt and prevents the skirt from shifting during bolt fixing, making the positioning operation of the train skirt more convenient and faster, reducing the labor intensity of workers, and improving work efficiency.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] In one embodiment, such as Figures 1-5 As shown, a train skirt locking device includes a housing 1, a mounting plate 2, a fixing cylinder 3, and a pin cylinder 8. The housing 1 and the mounting plate 2 are both disposed on the side wall of the train. The pin cylinder 8 is disposed inside the train skirt. The mounting plate 2 is connected to the train skirt by bolts. The fixing cylinder 3 is fixedly connected to the inner side wall of the housing 1. The pin 5 is slidably connected to the inner side wall of the fixing cylinder 3. The pin 5 is slidably connected to the inner side wall of the pin cylinder 8.

[0023] Raise the train skirt panel to the position of the four fixed cylinders 3, and align the pin cylinder 8 with the pin 5, so that the pin 5 enters the pin cylinder 8, which can limit the movement of the train skirt panel along the X-axis.

[0024] In one embodiment, the side wall of the fixed cylinder 3 is provided with a U-shaped groove 10, and the side wall of the pin 5 is fixedly connected with a pull block 6, which is slidably connected to the inner side wall of the U-shaped groove 10.

[0025] Manually pull the pin 5 into the fixed cylinder 3 using the pull block 6, and move and rotate the pull block 6 according to the trajectory of the U-shaped groove 10 to lock the pull block 6 into the U-shaped groove 10. At this time, the pin 5 is fully inserted into the fixed cylinder 3.

[0026] In one embodiment, a rotating plate 11 is connected to the pin 5 via a bearing, and a spring 9 is fixedly connected between the rotating plate 11 and the inner wall of the fixed cylinder 3.

[0027] Spring 9 allows pin 5 to maintain its maximum movement along the X-axis. At this time, the locking bolt hole of pin 5 is aligned with the locking bolt hole of fixed cylinder 3, making it convenient for manual screwing in of locking bolt 7.

[0028] In one embodiment, both the fixed cylinder 3 and the pin 5 have locking bolt holes on their sidewalls, and the locking bolt 7 is threadedly connected to the pin 5.

[0029] The locking bolt 7 can fix the position of the pin 5, preventing the pin 5 from moving left or right during train operation, causing it to come off and affecting the positioning of the pin 5 on the Y-axis of the train skirt.

[0030] In one embodiment, the housing 1 is bolted to a cover 4.

[0031] The above embodiments disclose a train skirt locking device, the specific working principle and process of which are as follows:

[0032] Manually pull the pin 5 into the fixed cylinder 3 using the pull block 6, and move and rotate the pull block 6 according to the trajectory of the U-shaped groove 10 until the pull block 6 is locked in the U-shaped groove 10. At this point, the pin 5 is fully inserted into the fixed cylinder 3. Raise the train skirt panel to the position of the four fixed cylinders 3, align the pin cylinder 8 with the pin 5, and then move and rotate the pull block 6 again according to the trajectory of the U-shaped groove 10 to allow the pin 5 to enter the pin cylinder 8. This can limit the movement of the train skirt panel along the X-axis.

[0033] Then, use bolts to fix the train skirt to the mounting plate 2 for limiting and fixing along the Y-axis direction;

[0034] By limiting and fixing the train skirt along the X-axis and Y-axis, the fixing effect of the train skirt is further improved, avoiding the situation where the train skirt will warp when the bolts come loose during the train's operation, which is common in ordinary one-way positioning.

[0035] When bolting the train skirt, it is often necessary to hold the train skirt by hand, and the train skirt is also prone to displacement, making the positioning operation inconvenient. However, by setting the pin 5, the limit in the X-axis direction can be set before bolting in the Y-axis direction, and this can be achieved simply by pulling the pin 5. This allows for quick pre-fixation of the train skirt before subsequent bolt tightening, reducing the time spent manually lifting the train skirt. The train skirt is also less prone to displacement when bolting, making the positioning of the train skirt more convenient.

[0036] The locking bolt 7 can fix the position of the pin 5, preventing the pin 5 from moving left or right during train operation, causing it to come off and affecting the positioning of the pin 5 on the Y-axis of the train skirt.

[0037] Spring 9 allows pin 5 to maintain its maximum movement along the Y-axis. At this time, the locking bolt hole of pin 5 is aligned with the locking bolt hole of fixed cylinder 3, making it convenient for manual screwing in of locking bolt 7.

[0038] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
