A highly stable and adjustable railway track positioning fitting and its operation method

Abstract

The invention discloses a highly stable and adjustable railway track positioning accessory and an operation method thereof. The control sleepers are fixedly arranged on the base at equal distances, and the control sleepers are symmetrically arranged and connected with support pads; , The cooperation between the pre-positioning column piece and the adjustment and positioning accessories can be adjusted according to the actual construction requirements, and the positioning work has been completed before it is fixed. Fast and stable locking, replacing the bolt fixing method in the prior art, can ensure the accuracy of its position positioning, avoid the phenomenon of position offset and dislocation during the tightening process, ensure the construction quality, and avoid the repeated debugging of the staff. operation, improve work efficiency and ensure the economic benefits of the overall construction.

Description

technical field [0001] The invention relates to the technical field of railway track construction, in particular to a highly stable and adjustable railway track positioning fitting and an operation method thereof. Background technique [0002] Railway tracks are referred to as rails, rails, tracks, etc., which are mainly used on railways and cooperate with point switches to enable trains to walk without turning; railway tracks are usually composed of two parallel steel rails, which are fixed on the sleepers and sleepers. Below is the road ballast; it is fastened by railway accessories such as rail braces, fasteners, rail presses, road splints, elastic strips, and railway spikes. [0003] The Chinese patent document with the currently authorized publication number CN212670155U discloses a rail connection mechanism for railway track laying, which adopts the method of slowly advancing the first rail and the second rail along the length direction of the rail to cooperate and con...

Problems solved by technology

[0004] The above-mentioned scheme and the prior art all install and fix the rail on the sleeper, that is, fix it on the sleeper through the support pad, and fix the sleeper on the support base equidistantly. In the actual construction process, two Rails are used for positioning. The operation in the prior art is complicated and troublesome, and the error is relatively large. There is no corresponding control mechanism for auxiliary positioning. When fixing, fastening bolts are generally used for fastening, and the bolts are tightened. When it is used, it will also produce a certain error, which will cause the position of the support pad to shift, and the staff will need to carry out corresponding adjustments, which will greatly affect the work efficiency, the overall construction stability is not enough, and the quality cannot be guaranteed, thus affecting the overall economic benefits of construction
