AI Technical Summary

Technical Problem

Existing track fixing methods mostly use nut adjustment springs, which are difficult to meet multi-dimensional fixing needs, especially under complex operating environments and forces in different directions, the fixing effect is limited.

Method used

The multi-dimensional fixed track fasteners are used. Through the pre-embedded base plate, limit screws, limit nuts and unique fastening components, combined with buffer pads, the track can be fixed and shock-absorbing in multiple dimensions. The adjustment bolts drive the fixing blocks and limit blocks to tighten and limit the track by using the cooperation of limit rods and springs.

Benefits of technology

It improves the stability and reliability of the track, effectively meets the multi-dimensional fixing requirements in complex operating environments, reduces vibration damage to the track and fixing structure, extends service life, and enhances adaptability.

Abstract

The utility model relates to the technical field of rails, in particular to a multi-dimensional fixed rail fastener. According to the technical scheme, the device comprises a rail and a pre-embedded bottom plate arranged on the bottom face of the rail, two limiting screws are fixedly arranged on the upper surface of the pre-embedded bottom plate, and the limiting screws are each sleeved with a set of limiting nuts in a threaded mode; the limiting screw rod is movably sleeved with the supporting plate, and a fastening assembly used for fixing the track is fixedly arranged on the upper surface of the supporting plate. According to the rail fixing device, the rail can be stably fixed in a multi-dimensional mode, acting force in different directions can be effectively coped with, the stability and reliability of rail fixing are greatly improved, and the multi-dimensional fixing requirement under the complex operation environment is met.
