Description

Technical Field

[0001] The present application relates to the technical field of vibration isolation connectors, and specifically to a vibration isolation connector for rail vehicles. Background Technique

[0002] The existing vibration isolation connectors for rail vehicles are steel spring vibration isolation elements made of steel springs. The steel spring vibration isolation elements are used to elastically connect the ground and the floating slab, so that the vibration transmitted from the floating slab to the vehicle body can be slowed down through the elasticity and attenuation of the steel spring vibration isolation elements, thereby achieving the vibration isolation effect. In addition, during the working process of the steel spring vibration isolation elements, a large shear force is also borne along their axial direction, which requires a certain stability for the rubber steel spring vibration isolation elements. However, the current steel spring vibration isolation elements are difficult to achieve good stability, and it is not easy to replace the steel springs. Since the springs are consumables, when they reach a certain service life, if the replacement operation is not carried out in time, the use effect of the springs will be affected. Therefore, we propose a vibration isolation connector for rail vehicles to solve the above problems. Utility Model Content

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0023] Embodiment

[0024] Please refer to Figures 1-4 , a vibration isolation connecting piece for a rail vehicle, comprising a fixing plate 1 and a fixing seat 4. The bottom end of the fixing plate 1 is provided with a support seat 8 through a sliding mechanism; the top end of the fixing plate 1 is fixedly installed with a connecting plate 3 through a plurality of springs 2. The top end of the connecting plate 3 is fixedly installed with a plurality of fixing columns 6. A plurality of fixing grooves 5 are opened at the bottom end of the fixing seat 4, and the top end of each fixing column 6 is respectively clamped with each fixing groove 5. A screw rod 7 is longitudinally slid and rotatably installed in the middle area of the connecting plate 3. The top end of the screw rod 7 is fixedly installed with a limiting plate 31, and the bottom area of the screw rod 7 is screwed with the top end of the fixing plate 1; the bottom end of the fixing plate 1 is attached to the top end of the support seat 8; a sliding groove 9 is opened at the top end of the support seat 8, and a slider 10 is slidably installed on the sliding groove 9. The slider 10 is fixedly installed at the bottom end of the fixing plate 1; two protective plates 13 are symmetrically attached to the top end of the support seat 8. A fixing screw 14 is screwed on each protective plate 13, and the bottom area of each fixing screw 14 is screwed with the top end of the support seat 8. Through the installation of the protective plate 13 and the fixing screw 14, the other end of the outer side wall of the fixing plate 1 is fixed. Two limiting frames 12 are symmetrically fixedly installed at the top end of the support seat 8, and the outer side wall of each limiting frame 12 is attached to the outer side wall of the fixing plate 1. By installing the limiting frame 12, the fixing plate 1 performing the sliding operation is limited.

[0025] Please refer to Figures 1-4 , a damper 11 is arranged inside each spring 2. For this vibration isolation connecting piece for a rail vehicle, through the expansion and contraction of the spring 2, effective buffering and vibration reduction operations are performed on the rail vehicle at the top end of the fixing seat 4 through the transmission of the connecting plate 3, the fixing column 6 and the fixing seat 4. Through the sliding operation of the slider 10 on the sliding groove 9 opened on the support seat 8, it is convenient to quickly replace the fixing plate 1 and the spring 2 at the top end of the fixing plate 1. By screwing the screw rod 7 with the top end of the fixing plate 1, the connecting plate 3 is driven to compress the spring 2, so that the fixing column 6 is separated from the fixing seat 4, thereby facilitating the quick disassembly and replacement operations of the spring 2, ensuring the use effect of the spring 2, improving the working efficiency of workers, and improving the practicability.

[0026] Please refer to Figure 1, it should also be noted that a rotating disk 15 is fixedly installed on the outer side wall of the screw rod 7. The rotating disk 15 is located below the connecting plate 3. By installing the rotating disk 15, it is convenient for the user to rotate the screw rod 7.

[0027] Please refer to Figure 1 , a plurality of top plates 16 are fixedly installed at the top end of the fixed plate 1. By installing the top plates 16, the telescopic spring 2 is limited.

[0028] In summary, when the vibration isolation connector for rail vehicles is in use, through the cooperation of the spring 2 and the damper 11, the track and the vehicle at the top end of the fixed seat 4 are buffered. When the spring 2 needs to be replaced, the fixing screw 14 is rotated, so that the protection plate 13 is separated from the support seat 8. Since the screw rod 7 and the top end of the fixed plate 1 are screwed, when the rotating disk 15 is rotated, the screw rod 7 is driven to rotate synchronously. Through the rotation operation of the screw rod 7 and the top end of the fixed plate 1, the connecting plate 3 moves under the limitation of the limiting plate 31. Through the movement of the connecting plate 3, the spring 2 is compressed, so that the fixing column 6 is separated from the fixing groove 5 opened at the bottom end of the fixed seat 4. The slider 10 at the bottom end of the fixed plate 1 slides in the sliding groove 9 opened at the top end of the support seat 8, so that the fixed plate 1 drives the spring 2 to be separated from the support seat 8. The fixed plate 1 and the spring 2 to be replaced are operated in the reverse process of the above operation, and the fixed plate 1 and the spring 2 are reinstalled.

[0029] Although the embodiments of the present application have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present application.
