Description

Technical Field

[0001] The utility model relates to the technical field of expansion joints, in particular to an expansion joint forging for connecting structural parts. Background Art

[0002] At present, expansion joints are set at appropriate positions on contact rails to adjust the thermal expansion and contraction caused by environmental changes and temperature rise, and are important components of the contact rail system. However, there are still some shortcomings in the expansion joints used today: when connecting two sets of hollow rails, the expansion joints need to be inserted into the two sets of rails, and then they are screwed together by corresponding external bolts. When screwing together, the operator needs to tighten the rails and joints to prevent the two from moving relative to each other and being unable to quickly screw the bolts together. This not only requires the operator to tighten the rails for a long time, which increases labor consumption, but also easily causes the rails and joints to move relative to each other, affecting the subsequent screwing quality. Therefore, we propose an expansion joint forging for connecting structural parts.

[0003] The application number is 202122729391.9, which discloses an expansion joint forging for connecting bridges, including an expansion joint, and sliding grooves are provided at both ends of the upper and lower sides of the expansion joint, and each sliding groove is penetrated and movably installed on a push plate. The utility model can make the rotating rod rotate with the fixed rod as the center of the circle as the expansion joint is inserted through the horizontal movement of the push block at the bottom and the push block is pressed and pushed, so that the clamping plate on the side of the rotating rod rotates and fits against the inner wall of the track. The synchronous relative rotation of the two sets of clamping plates ensures that the expansion joint can be initially and stably fitted to the inner wall of the track, thereby simplifying the operating steps required for clamping and avoiding the labor consumption of the operator for long-term hand-held clamping during the subsequent screwing process, thereby improving the subsequent screwing efficiency, which is more practical and suitable for wide promotion and use.

[0004] However, there are some shortcomings: although the expansion joint structure adopted by the device takes into account the efficiency of screwing and is more convenient, it cannot guarantee the sealing and fixity of the expansion joint. Utility Model Content
