Abstract
The utility model discloses a novel height-measuring tape for a coal mine tunnel. The novel height-measuring tape is mainly formed by combining a stainless steel telescopic rod with a steel measuring tape. The novel height-measuring tape is characterized in that the distance from a lower telescopic rod to the reading position of the steel measuring tape is a fixed value; the lower end of the steel measuring tape is fixed in a handle, and the upper end of the steel measuring tape is fixed at the upper end of an upper telescopic rod; and the degree of the steel measuring tape can be read from a transparent part of the handle. The novel height-measuring tape for the coal mine tunnel has the advantages of simple structure, convenience in carrying, error reduction and time saving.
Description
Technical field
The utility model relates to height measuring device, especially relates to a kind of novel coal mine roadway height measuring device.
Background technology
At present, a lot of collieries need for a few thing, need measure some basic parameters of underworkings, such as head-room, width and tunnel area.Although just can directly measure width, highly survey the comparison difficulty with tape measure.Surveying high great majority now is with a telescopic pole; When it runs into the top, tunnel, to cross it again and survey its length, the high mode of such survey is not only not too convenient; Also may occur than mistake; Because to the process of horizontality, may slide to some extent, thereby make test data not accurate enough by the junction from vertical for pole.
Summary of the invention
The utility model purpose is to overcome the deficiency of above condition, and a kind of novel coal mine roadway height measuring device is provided.
The utility model solves the technical scheme that its technical matters adopted: a kind of novel coal mine roadway height measuring device; It is by expansion link and steel tape be combined into; Expansion link is divided into upper and lower two parts, but and two flexible, be handle in two-part junction; Handle inside is provided with the steel tape dish, and the upper end of steel tape is fixed on the upper end of expansion link; Following expansion link is fixed value 1.5m to tape measure Pan Dushuochu, when last expansion link is stretched to certain position, and can be from the transparent steel tape number of degrees of reading of handle.
The utility model compared with prior art can produce following good effect:
When 1) measuring head-room, avoided from the vertical reading error to the horizontality process;
When 2) measuring head-room, practiced thrift from vertically to the horizontality process during this period of time;
3) the utility model is simple in structure, and is cheap, is easy to carry, easy to use, can reduce error, saves time.

Embodiment
Below in conjunction with accompanying drawing the practical implementation of the utility model is done further to describe:
Embodiment one: a kind of novel coal mine roadway height measuring device of the utility model, following expansion link is all stretched, and vertically be placed on the ground; To go up expansion link and steel tape stretches lentamente; Touch the tunnel until its top, read the number of degrees of steel tape and add 1.5m this moment, is exactly height of tunnel.
