Embodiment Construction

[0026] see figure 1 with figure 2 , shows the built-in regulator of the slab track bed of the present invention.

[0027] The slab track bed built-in regulator includes a slab track bed built-in fixer 1 and a built-in adjustment mechanism 2, the built-in fixer 1 is embedded in the slab track bed, see figure 2 , which can be four symmetrically arranged and distributed in the four positioning holes of the slab-type track bed. The built-in adjustment mechanism 2 is installed in the arranged built-in fixer 1 to form a supporting position for the entire track bed, so that Precisely adjust the position and height of the bed plate.

[0028] Wherein, the built-in fixer 1 can be made of MC nylon to improve connection strength and effect, see image 3 , the built-in fixer 1 is a cylindrical structure, the inner edge of which is provided with a coarse tooth internal thread 11, and the outer edge is provided with a plurality of annular bosses arranged at intervals. During fixing, the...

Abstract

The invention relates to a plate type roadbed built-in adjuster. The plate type roadbed built-in adjuster comprises plate type roadbed built-in fixators and built-in regulating mechanisms, wherein the built-in fixators are embedded in a plate type roadbed, and are arrayed and distributed in positioning holes of a plate type roadbed plate; the built-in regulating mechanisms are mounted in the built-in fixators which are well arranged so as to perform bearing positioning to the whole roadbed plate, and the position height of the roadbed plate is accurately regulated. The integral structure of the plate type roadbed built-in adjuster disclosed by the invention adopts the combination of a plurality of small components, and built-in screw threads are buried in advance and casted, so that transporting the plate type roadbed plate is facilitated, the structures of the built-in regulating mechanisms are compact and precise, and coarse adjustment and fine adjustment exist; vertebral body structures and center holes are designed in the regulating mechanisms, so that disassembling operation after the casting is facilitated; the regulating accuracy is improved, the construction efficiency is improved, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field related to height adjustment of a ballast bed, in particular to a built-in adjuster of a slab ballast bed. Background technique [0002] It is relatively difficult to adjust the existing track bed slab, and there are few suitable tools. [0003] For this reason, in view of the above-mentioned defects, the designer of the present invention researched and designed a built-in adjuster for the slab track bed to overcome the above-mentioned defects by concentrating on research and design, and integrating experience and achievements in related industries for many years. Contents of the invention [0004] The object of the present invention is to provide a built-in adjuster for a slab track bed, which has a simple structure and is easy to operate, and can efficiently and conveniently realize the adjustment of the positioning accuracy of the track bed slab to meet different requirements. [0005] In order to solv...
