Background technology
Railway has been realized raising speed by a large scale at present, in order to firmly establish the theory of security developments, scientific development, guarantee that safety of railway traffic is stable, therefore the corresponding raising of the quality index of rail track has also proposed the higher quality requirements to the test measuring device of rail track.Railway gauge rule is one of special measuring tool that detects rail track.Its quality will directly affect the quality of rail track.Patent ZL201220121895.0 scale class standard railway gauge rule, by using, scheme is feasible.But blemish in an otherwise perfect thing is to live in surveying seat, needs to improve Gu the survey seat is taken the rail level wearing quality.Because gauging rule has the requirement of insulating property, survey seat so live, must insulate Gu survey the material of seat, generally be to adopt engineering plastics to make.In use, live to survey seat, a solid rail level of taking of surveying at first contacts with rail surface, and contact frequency is very high, and one-period (three months) gets off, and frequency of exposure reaches more than 100,000 times, and taking rail level all can have in various degree wearing and tearing.If survey the severity that seat is taken the rail level wearing and tearing, will affect the measuring accuracy of the measuring accuracy, particularly superelevation of gauging rule.At present, survey the material of seat and generally select the enhancing tenacity increased nylon, 0 grade, 1 grade gauging rule one-period gets off and must change, and 2 grades of gauging rules use two cycles also must change at most.In order to address this problem, the employing steel plate that has is fixed on live to be surveyed seat and admittedly surveys the taking on the rail level of seat, although this scheme has temporarily solved the wearing quality problem, it has increased manufacture difficulty and maintenance difficulty, and cost is also very high.The utility model adopts antifriction metal (AFM) to be embedded in to live surveys seat, and a solid scheme of surveying in the seat has improved surveys seat alive, a solid wearing quality of taking rail level of surveying, and making and keep in repair also very simply, cost is low, and cost performance is very high.
Summary of the invention
The purpose of this utility model is to provide a kind of standard railway gage chi, this gauging rule has changed seat, the solid not wear-resisting fault of construction of seat of surveying surveyed alive, inlay antifriction metal (AFM) the survey seat of living, the solid survey in the seat, increase the wearing quality that it takes rail level, thus measuring accuracy and the serviceable life of assurance gauging rule.
The purpose of this utility model is achieved through the following technical solutions:
The standard railway gage chi, described gauging rule includes blade, lives and survey seat, solid survey seat, the gauge head of living, solid gauge head, active end insulation sleeve, insulation sleeve, rail gauge measuring apparatus, ultra-high measurement mechanism, handle assembly and shock attenuation device, described living surveyed seat, Gu survey the below, two ends that seat is installed in blade, the gauge head of living is connected with rail gauge measuring apparatus, Gu gauge head is installed on the solid survey seat, antifriction metal (AFM) is embedded in to live and surveys in seat and the solid framework of surveying seat, is point-like and is evenly arranged; The framework of surveying seat and solid survey seat alive is fixed on the blade through screw, the active end insulation sleeve is installed in the front end of blade, insulation sleeve is installed in the rear end of blade, rail gauge measuring apparatus, ultra-high measurement mechanism, handle assembly are installed in the top of blade, and shock attenuation device is installed in the both sides of the following and ultra-high measurement mechanism of gauge head alive, solid gauge head.
Described standard railway gage chi, described antifriction metal (AFM) be cylindric or triangle column or polygon column fixing, plug-type be embedded in to live survey in seat 1 and the solid framework of surveying seat.
Advantage of the present utility model and effect are:
1. the utility model adopts antifriction metal (AFM) to be embedded in the seat of surveying alive, Gu in the survey seat, so that the seat of surveying alive improves greatly Gu the survey seat is taken the rail level wearing quality.
2. the utility model has the accuracy of measurement height by application attestation, and is easy to operate, easy-maintaining, and the characteristics such as life-span length have been filled up the blank of China's scale class standard railway gauge rule without 0 class precision grade.
3. the utility model is easily made, easy-maintaining, and cost is low, and cost performance is high.
