Abstract
The utility model provides a measure instrument of elbow in pit, include: the protractor comprises a protractor body, a first graduated scale, a second graduated scale and a fixing pin, wherein the first graduated scale and the second graduated scale are overlapped and are rotationally fixed at the circle center of the protractor body through the fixing pin. The utility model discloses an instrument of measurement elbow in pit realizes angle and the length of accurate measurement elbow simultaneously.
Description
Technical Field
The utility model relates to a measuring equipment field, in particular to measure instrument of elbow in pit.
Background
In order to lay the underground laid pipeline according to the standardized requirements after the underground roadway turns or the underground chamber is constructed, an elbow is often additionally arranged at the turning position of the roadway or the underground chamber, the elbow is usually a standard elbow, the angle and the length of the elbow are fixed, the underground production requirement cannot be met, the elbow needs to be machined according to the actual situation of the underground site, the angle and the length of the elbow need to be accurately measured, and multiple reworking can be caused if the measurement is inaccurate, so that the labor intensity is increased, and the operation efficiency is reduced.
SUMMERY OF THE UTILITY MODEL
For solving the unable accurate problem of measurement of elbow angle and length in the pit among the prior art, the utility model provides a measure instrument of elbow in the pit.
The technical scheme of the utility model is realized like this:
a tool for measuring downhole bends, comprising: the protractor comprises a protractor body, a first graduated scale, a second graduated scale and a fixing pin, wherein the first graduated scale and the second graduated scale are overlapped and are rotationally fixed at the circle center of the protractor body through the fixing pin.
Preferably, the first scale is a retractable scale.
Preferably, the second scale is a retractable scale.
Preferably, the protractor is made of stainless steel.
Preferably, the first graduated scale and the second graduated scale are made of stainless steel.
Preferably, scales are arranged on the front and back surfaces of the protractor.
Preferably, scales are arranged on the front and back surfaces of the first graduated scale and the second graduated scale.
Preferably, in the tool for measuring the downhole elbow, two transparent gaskets are further included, the two transparent gaskets are respectively arranged on the inner sides of the first graduated scale and the second graduated scale, one transparent gasket is located between the first graduated scale and the protractor, and the other transparent gasket is located between the second graduated scale and the protractor.
The utility model has the advantages that: the utility model discloses an instrument of measurement elbow in pit utilizes protractor and pivoted first scale and second scale, realizes the accurate measurement to elbow angle and length simultaneously. And simple structure, the cost of manufacture is low, and portable improves the operating efficiency.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings needed to be used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without inventive exercise.
Fig. 1 is a schematic structural view of an embodiment of a tool for measuring a downhole elbow according to the present invention.
In the figure:
1. a protractor; 2. a first scale; 3. a second scale; 4. and fixing the pin.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
A tool for measuring downhole bends, as shown in fig. 1, comprising: protractor 1, first scale 2, second scale 3 and fixed pin 4, first scale 2 and the stack of second scale 3 to fix the centre of a circle department at the protractor through fixed pin 4 pivoted. First scale and second scale all set up to the telescopic scale, are convenient for be suitable for and measure the not elbow of equidimension.
The protractor 1 is made of stainless steel. First scale 2 and second scale 3 adopt stainless steel. Scales are arranged on the front and back surfaces of the protractor 1. The front and back surfaces of the first graduated scale 2 and the second graduated scale 3 are provided with scales. The protractor, the first graduated scale and the second graduated scale are structured, so that the wear resistance and the use convenience of the protractor are improved.
In the instrument of measurement elbow in the pit, still include two transparent gaskets, set up respectively the inboard of first scale and second scale, a transparent gasket is located between first scale and the protractor, and another transparent gasket is located between second scale and the protractor for the stability of first scale and second scale when further guaranteeing to measure avoids first scale or the relative protractor of second scale to slide or rotate.
In the using mode, the first graduated scale is fixed to 0 degree, then the second graduated scale reads out the angle on the protractor through rotation, and then the first graduated scale and the second graduated scale stretch out and draw back to read out the length, so that the angle and the length of the elbow to be machined can be accurately measured.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
