Embodiment 1

[0041] The measuring device of a kind of vertical track verticality and flatness of this example is applied to the measurement of the verticality of the vertical track, including a measuring unit and a positioning unit, and the measuring unit is a total station; figure 1 As shown, the positioning unit includes a measuring rod 1, a connecting piece 2 and a magnetic base 3; wherein, the measuring measuring rod 1 is fixed on the upper surface of the magnetic base 2 through the connecting piece 2; the flatness of the bottom surface of the magnetic base 2 is less than 0.005mm. Measuring rod 1 is an inner diameter micrometer measuring rod with an accuracy of 0.005mm; the cross section of connecting piece 2 is a T-shaped cylindrical structure, the top end is provided with connecting piece thread groove 22, the lower part is connecting piece threaded rod 21, connecting piece thread groove 22 and measuring The threaded rod 12 at the tail end of the measuring rod 1 is matched and connect...

Embodiment 2

[0060] A kind of perpendicularity measuring device of this example is applied to the perpendicularity of the vertical plane in the narrow space. The basic structure is the same as that of embodiment 1, and the improvement is that: the side of the magnetic base 3 is provided with a magnetic on-off knob 32; and the whole positioning The unit is miniaturized to facilitate positioning in a small space; the measuring unit is the theodolite.

[0061] The measuring method of the measuring device of vertical track verticality and flatness of this example, its step is basic embodiment 1, and difference is: step D, measuring unit selection: the theodolite is placed on its eyepiece and can see inner diameter micrometer amount The position of the measuring rod convex surface 11 of the rod; step H is not required, only the verticality of the vertical plane in the narrow space is detected.

Embodiment 3

[0063] A kind of flatness measuring device of this example is applied to the flatness of the plane in the closed space, and the structure is the same as that of embodiment 2, and the closed space needs to be provided with a visible window (such as a glass window) that can be observed from the outside. The difference is: measurement The unit is a spirit level.

[0064] A vertical rail verticality and flatness measuring device and its measuring method of this example, its steps are basic embodiment 2, the difference is: step D, measuring unit position selection: place the spirit level on its eyepiece to see The position of the measuring rod convex surface 11 of the inner diameter micrometer measuring rod; step H is not required, only the flatness of the plane in the closed space is detected.

Abstract

The invention discloses a measuring device for perpendicularity and planeness of a vertical type rail and a measuring method thereof, and belongs to the technical field of measurement of the perpendicularity and planeness. The measuring device for the perpendicularity and planeness of the vertical type rail comprises a measuring unit and a positioning unit. The measuring unit comprises a total station or a theodolite or a gradienter. The positioning unit comprises a measuring rod, a connecting piece and a magnetic base. The measuring rod is fixed to the upper surface of the magnetic base through the connecting piece. The planeness of the bottom face of the magnetic base is smaller than 0.005 mm. The measuring method includes the steps of assembling, absorbing, zero returning, measuring unit position selection, eyepiece observation, adjusting, measuring point replacement and rail debugging. According to the device and the method, the measuring unit and the positioning unit are arranged in a separated mode, the positioning unit achieves accurate positioning through the measuring rod and attraction by the magnetic, and the purpose of accurate measuring of the perpendicularity and planeness in any space without being affected by external factors can be achieved.

Description

technical field [0001] The invention belongs to the technical field of verticality and flatness measurement, and in particular relates to a measuring device and a measuring method for the verticality and flatness of a vertical track. Background technique [0002] During the installation and commissioning of the vertical track, it is necessary to use measuring tools to measure the flatness and verticality of the vertical track. In the past, when measuring the verticality and flatness of vertical rails (or planes), the common method was to use pendants and steel tapes to measure the verticality and flatness of the equipment. This method is extremely susceptible to wind, vibration and other factors. It is not easy to control, and the reading accuracy of the steel tape is low, resulting in poor measurement accuracy. [0003] Chinese Patent Publication No.: CN105004252A, Publication Date: 2015.10.28 discloses a method for detecting the perpendicularity between the splicing surfa...
