Description

Technical Field

[0001] The utility model relates to the technical field of rail transit connection components, and particularly relates to a modular aluminum profile connection component for rail transit. Background Technique

[0002] With the rapid development of rail transit, the requirements for the performance and safety of vehicles are getting higher and higher. As the main structural material of rail transit vehicles, the performance of the connection components of aluminum profiles directly affects the overall performance and safety of the vehicles.

[0003] In the prior art, through retrieval, it is found that the Chinese patent discloses "an aluminum profile structural member for rail transit", and its application number is "202121410231.1". This patent mainly includes a track body and a connection component. One side of the track body is provided with a through hole, and a bolt is installed through the through hole. The connection component includes an embedded frame, and one side of the top end of the embedded frame is mutually attached to one side of one end of the track body. A fixed block is fixedly installed at the top end of the embedded frame. One end of the bolt penetrates through the fixed block, and nuts are connected to the left and right sides of the fixed block. Four groups of support plates are connected to one side of the embedded frame, and a support plate is jointly connected to one side of the support plates. A fixed seat is fixedly installed on one side of the support plate, and a touch switch is fixedly installed on one side of the fixed seat. A thimble is installed on one side of the embedded frame at a position corresponding to the touch switch. A spring is fixedly installed on the outer side of the embedded frame near the thimble, and one end of the spring abuts against the fixed seat. Although the above aluminum profile structural member for rail transit has relatively high overall stiffness, strength and stability, and can effectively ensure the normal use of the track. However, when using bolts and nuts to connect the connection component and the track body in the above structural member, it is necessary to open holes in the track body, and the opening of the holes will weaken the cross-sectional area of the track body, thereby reducing its structural strength and stability, which may affect the safety and normal operation of rail transit; and when setting springs and support plates to meet the buffering requirements, the deformation ability of the support plates made of rigid materials after being stressed is limited, which is prone to stress concentration and rapid damage, and the fixed structure between the support plates, the support plate and the connection component makes it inconvenient to maintain and replace the support plates. Therefore, the utility model provides a modular aluminum profile connection component for rail transit to solve the problems raised in the above background technique. Summary of the Utility Model

The function of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model. However, it should not be construed as a limitation on the protection scope of the present utility model.

[0023] Referring to Figures 1-4 , in an embodiment of the present utility model, a modular aluminum profile connecting member for rail transit includes a rail body 1, an embedded part 2, a connecting member 7, and a connecting plate 4. A plurality of first screws 3 are evenly and fixedly connected to the top of the embedded part 2. The connecting plate 4 is connected to the first screws 3 through first nuts 5. The connecting member 7 is attached to the outer side of the rail body 1, and a buffer pad 6 is provided between the connecting plate 4 and the connecting member 7. A U-shaped lower mounting plate 14 is fixedly connected to the side of the connecting member 7 close to the connecting plate 4. The buffer pad 6 is located inside the lower mounting plate 14. After the connecting member 7 is attached to the outer side of the rail body 1, the buffer pad 6 is placed inside the lower mounting plate 14. The connecting plate 4 is connected to the first screws 3 through first nuts 5. The connection operation is simple and stable. Thus, by providing the buffer pad 6 between the connecting plate 4 and the connecting member 7, the rail body 1 can be buffered. Moreover, the overall structure is simple, and it is convenient to disassemble and assemble components such as the connecting member 7, the buffer pad 6, and the connecting plate 4, which is convenient for maintenance and has strong practicability.

[0024] A second screw 8 is fixedly connected to the top of the connecting member 7. A support plate 10 is attached to the outer side of the rail body 1 and above the second screw 8. A third screw 11 is fixedly connected to the bottom of the support plate 10. The top of the second screw 8 is threadedly connected to an internal thread sleeve 9, and the bottom of the third screw 11 is threadedly connected to the internal thread sleeve 9. The internal thread sleeve 9 is threadedly connected to the outer side of the second screw 8. Move the support plate 10 to be attached to the outer side of the rail body 1, and rotate the internal thread sleeve 9 to be threadedly connected to the third screw 11, then the connection work between the connecting member 7 and the support plate 10 can be completed. Furthermore, under the action of the support plate 10, the connecting member 7 can be better attached to the outer side of the rail body 1 to improve the connection stability between the connecting member 7 and the rail body 1.

[0025] An upper mounting plate 15 is attached to the top of the buffer pad 6. Two Z-shaped connecting pieces 16 are symmetrically and fixedly connected to the top of the upper mounting plate 15. Two fourth screws 17 are symmetrically and fixedly connected to the top of the connecting plate 4. Both of the two connecting pieces 16 are connected to the corresponding fourth screws 17 through third nuts 18. The upper mounting plate 15 can be fixed through the cooperation connection among the connecting pieces 16, the third nuts 18, and the fourth screws 17. Thus, under the action of the upper mounting plate 15, the buffer pad 6 can be better fixed. Moreover, the movable mounting method of the upper mounting plate 15 is convenient for disassembly to facilitate the replacement operation of the buffer pad 6, which is convenient to use.

[0026] On one side of the connecting member 7 and the support plate 10 that are in contact with the track body 1, anti-slip pads 19 are provided. The anti-slip pads 19 are used to increase the friction between the connecting member 7 and the support plate 10 and the track body 1, so that the connecting member 7 and the support plate 10 can be more closely attached to the track body 1.

[0027] On the outer sides of the second screw 8 and the third screw 11, second nuts 13 that are in contact with the ends of the internal thread sleeves 9 are threadedly connected. The second nuts 13 screwed onto the second screw 8 and the third screw 11 can enhance the stability of the connection between the second screw 8, the third screw 11 and the internal thread sleeve 9.

[0028] The connecting member 7, the support plate 10 and the two anti-slip pads 19 are all provided with an L-shaped structure. The L-shaped anti-slip pads 19 can increase the contact area with the track body 1 to improve the stability of the connection between the connecting member 7 and the support plate 10 and the track body 1.

[0029] On the outer side of the internal thread sleeve 9, two handles 12 are symmetrically and fixedly connected. By operating the handles 12, the internal thread sleeve 9 can be driven to rotate, making the rotation of the internal thread sleeve 9 more convenient.

[0030] Working principle: First, move the connecting member 7 to fit against the outer side of the track body 1, place the buffer pad 6 inside the lower mounting plate 14, and connect the connecting plate 4 to the first screw 3 through the first nut 5. The connection operation is simple and stable. Thus, by arranging the buffer pad 6 between the connecting plate 4 and the connecting member 7, the track body 1 can be buffered;

[0031] Then move the support plate 10 to fit against the outer side of the track body 1, and rotate the internal thread sleeve 9 to be threadedly connected with the third screw 11, so that the connection work between the connecting member 7 and the support plate 10 can be completed. Furthermore, under the action of the support plate 10, the connecting member 7 can be better attached to the outer side of the track body 1 to improve the stability of the connection between the connecting member 7 and the track body 1;

[0032] Fit the upper mounting plate 15 against the top of the buffer pad 6. The upper mounting plate 15 can be fixed through the cooperation connection between the connecting member 16, the third nut 18 and the fourth screw 17. Thus, under the action of the upper mounting plate 15, the buffer pad 6 can be better fixed, and the movable mounting method of the upper mounting plate 15 is convenient for disassembly to facilitate the replacement operation of the buffer pad 6. The overall structure is simple, and the connecting member 7, the buffer pad 6, the connecting plate 4 and other components that are easy to disassemble and assemble are convenient for maintenance and have strong practicability.
