Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of traction equipment, in particular to a traction connecting piece for rail transportation. Background Art
[0002] Traction connectors for rail transit play a vital role in train operation and are one of the key components to ensure the safe and smooth operation of trains. Traction connectors can transmit the traction force during train operation and ensure that the train can run continuously and smoothly.
[0003] In the prior art, since the track has curved sections and ramps, the horizontality of the connectors cannot be guaranteed when rail vehicles pass through, resulting in uneven force on the connectors, which in turn causes wear of the connectors during the tilting and bending process, seriously affecting the life cycle of the connectors. The existing traction connectors are inconvenient to adjust their own height during installation, which makes the operation more difficult during installation, especially at the train connection. Due to the inconvenience of height adjustment, the installation process takes a long time and the installation quality is affected: it is difficult to ensure the perfect match between the traction connector and the train connection. Therefore, we propose a traction connector for rail transit. Utility Model Content

[0011] The technical effect of adopting the above-mentioned further scheme is: by connecting the buffer connecting rod with the buffer hydraulic rod, when the train is subjected to impact or vibration during operation, the buffer hydraulic rod and the buffer spring can work together to absorb and disperse the impact energy. By absorbing and dispersing the impact energy, the buffer hydraulic rod and the buffer spring can reduce the wear and fatigue between the various components of the train, thereby extending the service life of the train and its components.
[0012] As a preferred solution of the present invention, the support adjustment assembly includes an adjusting bolt, the adjusting bolt is threadedly connected to the buffer connecting rod, and a supporting foot is provided at the bottom of the adjusting bolt.

[0018] 2. In the present invention, the design of the support adjustment component facilitates the adjustment of its own height during installation, so that the traction connector can be quickly and accurately adjusted to the required height during the installation process, greatly shortening the installation time and improving work efficiency.
