Description

Technical Field

[0001] This application relates to the field of railway passenger car modification technology, specifically to an external structure for railway passenger car sleepers. Background Technology

[0002] To prevent the indiscriminate discharge of toilet waste during the use of Type 22 railway passenger cars, waste bins must be installed under the cars to collect and centrally treat the waste. However, the Type 22 railway passenger cars use tread-braced bogies, which limit the space outside the sleepers under the cars. When modifications to the waste bin installation structure are needed, the waste bins would interfere with the bogies or footboards, making such modifications impossible. Utility Model Content

Detailed Implementation

[0043] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this application are only for explaining this application and are not intended to limit this application.

[0044] like Figures 1-4As shown, this application embodiment provides a railway passenger car sleeper external structure, which is a modification of the existing railway passenger car sleeper external structure. The railway passenger car sleeper external structure includes a buffer beam 1, a traction beam 2, a side beam 3, a cross beam 4, a longitudinal beam 5, a waste bin assembly 6, and a footrest 7.

[0045] The buffer beam 1, traction beam 2 and side beam 3 are all basic structures of the original railway passenger car sleeper external structure; among them, there are two traction beams 2, which are arranged at intervals, and one end of the two traction beams 2 is perpendicularly connected to the middle of the buffer beam 1; the two side beams 3 are located on both sides of the traction beam 2 and are arranged parallel to the traction beam 2 at intervals, and one end of the side beam 3 is connected to the end of the buffer beam 1 through the footboard panel 8.

[0046] The crossbeam 4 is connected between the traction beam 2 and the side beam 3. The crossbeam 4 can be made of No. 18 channel steel. There are two crossbeams 4. One crossbeam 4 is connected between the side beam 3 on both sides and the traction beam 2. The two ends of the crossbeam 4 are fully welded to the traction beam 2 and the side beam 3 respectively. The crossbeam 4 is perpendicular to the traction beam 2 and the side beam 3. The crossbeam 4 is installed at a position 2070mm away from the sleeper beam in the outer structure of the railway passenger car in the length direction. This position can ensure that the waste bin assembly 6 will not interfere with the bogie in the outer structure of the railway passenger car after installation.

[0047] The longitudinal beam 5 connects the buffer beam 1 and the cross beam 4. The longitudinal beam 5 can also be made of No. 18 channel steel. There are two longitudinal beams 5. Each cross beam 4 is connected to the buffer beam 1. The two ends of the longitudinal beam 5 can be fully welded to the cross beam 4 and the buffer beam 1. On the side of the manual braking device in the outer structure of the railway passenger car sleeper, the distance between the longitudinal beam 5 on this side and the center line of the car body is 840mm. The longitudinal beam 5 at this position will not interfere with the manual braking device, nor with the spring structure on the foot pedal panel 8. On the side of the windshield structure in the outer structure of the railway passenger car sleeper, the distance between the longitudinal beam 5 on this side and the center line of the car body is 700mm. The longitudinal beam 5 at this position will not interfere with the windshield system on the buffer beam 1, nor with the spring structure on the foot pedal panel 8. At the same time, it can facilitate the installation of the waste bin assembly 6.

[0048] The waste bin assembly 6 is connected to the longitudinal beam 5.

[0049] Foot pedal 7 is connected to foot pedal enclosure 8, wherein the length of the lowest pedal in foot pedal 7 is less than the length of the upper pedal, so as to avoid the waste bin assembly 6.

[0050] The railway passenger car sleeper external structure provided in this application is a modification based on the existing railway passenger car sleeper external structure. By adding a crossbeam 4 and a longitudinal beam 5, a connection base is provided for the waste bin assembly 6 to form a stable support for the waste bin assembly 6. The length of the pedal at the bottom of the foot pedal 7 is reduced to avoid the waste bin assembly 6, so that the railway passenger car sleeper external structure has the function of waste collection.

[0051] In some alternative embodiments, such as Figure 2 As shown, the pedal 7 includes a first-level pedal 71, a second-level pedal 72, and a third-level pedal. The first-level pedal 71 is connected to the pedal surround 8 at both ends along its length. The second-level pedal 72 is connected to the pedal surround 8 at both ends along its length and is arranged parallel to and spaced apart from the first-level pedal 71. The second-level pedal 72 is the same length as the first-level pedal 71. One end of the third-level pedal is connected to the pedal surround 8 and is arranged parallel to and spaced apart from the second-level pedal 72. The length of the third-level pedal is shorter than that of the second-level pedal 72. The other end of the third-level pedal is connected to the second-level pedal 72 through a side plate assembly. In the working state, the third-level pedal is located at the bottom. This is equivalent to cutting off a certain length of the lowest pedal in the pedal 7 while keeping the width unchanged, ensuring that the third-level pedal functions normally.

[0052] In some optional embodiments, the side plate assembly includes a side plate body 74 and a side plate mounting plate 75; one end of the side plate body 74 is connected to the other end of the third-level pedal; the side plate mounting plate 75 is connected to the second-level pedal 72 and to the other end of the side plate body 74; wherein the surface of the side plate body 74 forms an angle with the surface of the second-level pedal 72.

[0053] In this embodiment, the inclined design of the side panel body 74 can reserve more space between the second-level pedal 72 and the third-level pedal, making it easier for people to get on the vehicle.

[0054] In some optional embodiments, the side plate mounting plate 75 is provided with a plurality of bolt holes spaced apart along the length direction, and the side plate body 74 is connected to the side plate mounting plate 75 by bolts; this can improve the connection strength between the side plate body 74 and the second-level pedal 72 and ensure the safety of the foot pedal 7.

[0055] In some optional embodiments, the waste bin assembly 6 includes a waste bin body and a mounting bracket; the mounting bracket is welded to the longitudinal beam 5, and the waste bin body and the mounting bracket are detachably coupled; this facilitates the maintenance and replacement of the waste bin.

[0056] In some optional embodiments, the hanger includes a hook 61 and a connecting plate 62; the hook 61 is welded to the longitudinal beam 5, and the number of hooks 61 can be set to multiple, with multiple hooks 61 arranged parallel and spaced along the length of the longitudinal beam 5, and each hook 61 is L-shaped; the connecting plate 62 is connected to the hook 61, and the connecting plate 62 is set as an L-shaped plate to form a larger connection area with the hook 61. The connecting plate 62 has a connection hole for fitting the waste bin body, wherein the waste bin body can be fitted with the connecting plate 62 by bolts, which ensures the connection strength and achieves the purpose of disassembly.
