Description

A device for measuring the height of an instrument

Technical Field

The utility model belongs to the technical field of outdoor height measurement and mapping, and particularly relates to a device for measuring the height of an instrument.

Background technique

The instrument height refers to the vertical distance from the center of the instrument dial to the measuring station. It is a basic parameter that must be input when performing elevation measurement and other work, and is the basic basis for subsequent internal calculations. Measuring the instrument height is an important task in surveying and mapping, and the accuracy of the instrument height directly affects the accuracy of the final measurement result. At present, the common method for measuring the instrument height is the steel ruler distance method, that is, a horizontal line is marked on the outer wall of the instrument, which is horizontal with the center of the instrument dial, and then the tape measure is used to directly measure the slant distance from the control point to the horizontal line marked on the instrument, and then a certain value is deducted according to the experience of the surveyor. This method is simple to operate and widely used, but the measurement error is large, and the human influence factor in the slant height measurement process is large. This is an unavoidable factor in precision engineering measurement. How to improve the measurement accuracy of the instrument height is a very important basic issue.

Summary of the invention

The purpose of the utility model is to solve the problem of low precision in the existing instrument height measurement, and provide a device for measuring the height of the instrument. The device can not only reduce the error when measuring the height of the instrument, but also facilitate on-site installation and disassembly without special tools.

In order to achieve the above purpose, the utility model adopts the following technical solutions:

A measuring device for measuring the height of an instrument, comprising a graduated ruler, a connecting plate, an upper fixing plate, a lower fixing plate and a tape fixing box;

The scale ruler is arranged vertically, and the bottom end of the scale ruler is fixedly connected to one end of a horizontally arranged connecting plate, and one end of an upper fixing plate and a lower fixing plate arranged horizontally are respectively fixedly connected to the lower part of the scale ruler, and the upper fixing plate and the lower fixing plate are used to fix the device to the instrument, and a tape measure fixing box is arranged at the other end of the connecting plate for placing the tape measure.

Furthermore, in the above-mentioned measuring device for measuring the height of the measuring instrument, the lower fixing plate is provided with fixing bolts for fixing the lower fixing plate below the instrument.

Furthermore, in the measuring device of the height of the measuring instrument, the middle part of the scale ruler is hollowed out.

Furthermore, in the measuring device for measuring the height of the measuring instrument, the top of the measuring tape fixing box has no top cover, the bottom is provided with a square hole, and the connecting plate is correspondingly provided with a same square hole.

Furthermore, in the measuring device for measuring the height of the measuring instrument, an elastic clip of the measuring tape is provided in the measuring tape fixing box.

Compared with the prior art, the beneficial effects of the present invention are:

1. This device can measure the distance between the connecting steel plate and the ground and the height of the instrument itself with high precision, and obtain the accurate overall height of the instrument by adding the two heights, which can effectively avoid the error caused by directly measuring the height of the instrument.

2. The device is easy to install and disassemble on site without the need for special tools.

Detailed ways

Example

A measuring device for measuring the height of an instrument, as shown in FIGS. 1 to 3 , comprises a graduated ruler 1 , a connecting plate 5 , an upper fixing plate 2 , a lower fixing plate 3 and a tape fixing box 6 ;

The scale ruler is arranged vertically, and the middle part of the scale ruler is hollowed out. The bottom end of the scale ruler is fixedly connected to one end of a horizontally arranged connecting plate. One ends of an upper fixing plate and a lower fixing plate arranged horizontally are respectively fixedly connected to the bottom of the scale ruler. The upper fixing plate and the lower fixing plate are used to fix the device to the instrument. A fixing bolt 4 is provided on the lower fixing plate for fixing the lower fixing plate under the instrument. A tape measure fixing box is arranged at the other end of the connecting plate for placing a tape measure. There is no top cover on the top of the tape measure fixing box, and a square hole is provided on the bottom. The same square hole is correspondingly provided on the connecting plate. A tape measure elastic clip 7 is provided in the tape measure fixing box.

When the utility model is used, the instrument base 8 is placed on the tripod and fixed, the platform 9 of the tripod and the instrument base are inserted between the upper and lower fixed plates of the device, and the platform and base of the tripod are fixed by fixing screws; then the measuring instrument 10 is placed on the base, and the height of the instrument is read through the hollow part of the scale ruler; the tape measure is placed in the tape measure fixing box, and the tape measure is fixed with the elastic clip of the tape measure, and the tape measure belt is pulled out from the hole below the tape measure fixing box to the ground, so that the height between the lower end of the connecting plate and the ground can be obtained, and the height of the instrument and the height from the instrument to the ground can be added to obtain the overall height of the instrument with high precision. Provide high-quality data support for the next step of measurement. After the measurement is completed, the device can realize the installation and disassembly of the measuring instrument on the platform without tools, and has a simple structure and is easy to use.
