Test device and test method for construction line type of tramway grooved rail laying

Abstract

The invention discloses a line type testing device for rail laying construction, which comprises two completely identical fixing mechanisms arranged from front to back, and the two fixing mechanisms are respectively a first fixing mechanism located at the opposite front side and a second fixing mechanism located at the rear side. The fixing mechanism is characterized in that a winding mechanism is fixed on the upper side of the first fixing mechanism, a reference positioning mechanism is fixed on the upper side of the second fixing mechanism, a measuring tape is connected between the winding mechanism and the reference positioning mechanism, and the winding mechanism There is also a measuring belt auxiliary support mechanism under the mechanism. After the positioning is completed, the winding mechanism can tighten the measuring tape and cooperate with the measuring tape auxiliary straightening device to keep the measuring tape in a horizontal and straight state, preventing the measuring tape from forming a radian and causing a large measurement error, making the measurement more accurate; And the side of the take-up roller fits the middle right side of the rail, so that the measuring tape is stretched along the side of the rail. When encountering a bend, the distance and line type can still be accurately measured, and the scope of application is wider.

Description

technical field [0001] The invention relates to the technical field of trough-shaped track laying construction, in particular to a testing device and a testing method for the laying construction line of a tramway trough-shaped rail. Background technique [0002] Modern tram is an advanced public transportation mode that is fully upgraded and transformed on the basis of traditional tram. It has the characteristics of medium capacity, novel design, environmental friendliness, and resource conservation. It can well meet the urban environment and social needs. Basic requirements for sustainable development. Since its application, it has been widely recognized by countries all over the world. At present, modern trams are operating in about 100 countries in Europe and more than 100 cities in North America, becoming one of the backbone forms of urban public transportation. In Asian countries such as Japan, modern trams are also widely used. [0003] Since the track structure of ...

Problems solved by technology

[0004] Most of the existing rail alignment detection methods are the method of pulling wire ropes, such as Chinese patent publication CN 210596850 U "a railway line rail alignment detection device" and CN 102409586 A "railway line rail alignment detection device and detection method", All disclose the method of using a pull wire rope to measure the rail shape. Since there is no accurate reference and reliable positioning device when fixing, the positioning is not accurate enough, and the measurement line cannot be guaranteed to be tight, forming a large arc that leads to the detection result The deviation is large, which affects the quality of tram rail laying
