Specific embodiment
The following describes the utility model in further detail with reference to the accompanying drawings, it is described be the explanation to the utility model and
It is not to limit.
As shown in Figure 1, a kind of mechanical horizontal measuring instrument, including shell 1, pointer 3, degree pointer 5, shot 9, degree is divided to refer to
Needle shaft 11 divides pointer driving shaft 16 and divides pointer driven shaft 19；
Wherein, which includes shell 2 and is mounted on its positive cover board 7, and shell 2 is the rectangular box of a side opening
Son, 7 spiral-lock of cover board close shell 2 in the open side of shell 2.
As shown in figure 3, cover board 7 is made of transparent hard plastic material, therefore it can intuitively see very much tooth in shell 1
The drive state of wheel, it is convenient for safeguarding.
The inside of shell 1 successively degree of being horizontally mounted needle pivot 11, transmission shaft 13 and divides pointer driving shaft 16 and from bottom to top
Divide pointer driven shaft 19, and is located in same vertical line；It spends needle pivot 11, transmission shaft 13 and divides pointer driving shaft 16 and point finger
One end of needle driven shaft 19 is connect with cover board, and the other end is connect with the bottom plate of shell 2.
As shown in Fig. 2, successively degree of installation pointer 5, degree pointer gear 10 and shot 9, degree pointer 5 are solid on degree needle pivot 11
Dingan County is located at the outside of cover board 7 mounted in the end of degree needle pivot 11, and degree of being provided with dial 6 on cover board 7 spends dial 6
Indicating range be ± 90 °.Degree pointer gear 10 and shot 9 are located at the inside of shell 1.Shot 9 passes through swing rod and degree needle pivot
11 are connected, and are located at the lower section of degree needle pivot 11 under gravity.
As shown in figure 4, the two sides of degree 11 horizontal process of needle pivot are also respectively provided with bar 8, prevent from shot 9 from turning over being more than
90°。
Shot 9 is connect by swing rod with degree needle pivot 11, and swing rod is welded with shot 9 and degree needle pivot 11 respectively.
As illustrated in figs. 5-7, transmission shaft gear wheel 14 and shaft pinion 12, the small tooth of transmission shaft are fixed on transmission shaft 13
Wheel 12 is engaged with degree pointer gear 10.
Divide on pointer driving shaft 16 and be fixed with point pointer internal gear 17 and divide pointer gear 15, divides pointer internal gear 17 close
The side of cover board divides pointer gear 15 to engage with transmission shaft gear wheel 14.
Divide on pointer driven shaft 19 and be fixedly installed a point pointer external gear 18, divides pointer external gear 18 and divide pointer internal gear
17 engagements；The end of point pointer driven shaft 19 is also fixedly installed with point pointer 3, the outside for dividing pointer 3 to be located at cover board 7, on cover board 7
It is provided with scale division disk 4, due to the numerical value for indicating that pointer 3 is divided to indicate.
Wherein, pointer gear 10 is spent, shaft pinion 12, transmission shaft gear wheel 14, divides pointer gear 15, divide in pointer
Gear 17 and pointer external gear 18 is divided to be straight spur gear, modulus m=1, the facewidth is b=5mm, and pressure angle is
20°。
Spend the tooth number Z of pointer gear 101=100；
The tooth number Z of shaft pinion 122=20；
The tooth number Z of transmission shaft gear wheel 143=100；
Divide the tooth number Z of pointer gear 154=25；
Divide the tooth number Z of pointer internal gear 175=60；
Divide the tooth number Z of pointer external gear 186=20.
When horizontal measuring instrument is placed on measuring surface, shot 9 under the effect of gravity, is remained vertically downward, shot band
Dynamic degree needle pivot rotation, spends 11 drive degree pointer 5 of needle pivot and degree pointer gear 10 rotates, and it is logical to spend pointer gear 10
Crossing shaft pinion 12 drives transmission shaft 13 to rotate, and transmission shaft 13 drives transmission shaft gear wheel 14 to rotate, transmission shaft gear wheel
14 drives divide pointer gear 15 to rotate, and divide pointer gear 15 by dividing the drive of pointer driving shaft 16 that pointer internal gear 17 is divided to rotate,
Divide pointer internal gear 17 to divide pointer 3 to rotate together to drive, realizes the horizontal measurement of measuring surface.
Gear ratio calculates as follows:
i16=Z2*Z4*Z6/Z1*Z3*Z5=20*25*20/100*100*60=1/60
I16 is for degree pointer gear 10 and to divide the transmission ratio between pointer external gear.
Therefore, every 1 circle of rotation of degree pointer gear 10, divides pointer internal gear 17 that need to rotate 60 circles, namely the degree every rotation of pointer 5
1 °, pointer 3 is divided to rotate 1/6 week, that is, is exactly to rotate 60 °, if feeding back to being exactly 60' on 4, to realize horizontal measuring instrument
Effectiveness of classification.Again according to the judgement in gear train assembly gear drive direction, spends pointer 5 and the direction of rotation of pointer 3 is divided to be one
It causes.To very convenient reading data.
The mechanical horizontal measuring instrument realizes horizontal measurement by accurate transmission ratio, can satisfy underground heading equipment peace
Required precision required for horizontal measurement is filled, and not be driven biggish torque, all gears can use plastic production,
Therefore at low cost, aspect is carried, and the horizontal measuring instrument is small in size, simple to operate, when worker can be carried around or is long
Between be placed in underground, the horizontal measurement of all engineering water planes suitable for classification, manufacturing cost is cheap, have bigger market
Value.
The above content is only to illustrate the technical idea of the utility model, and the protection model of the utility model cannot be limited with this
Enclose, it is all according to the utility model proposes technical idea, any changes made on the basis of the technical scheme each falls within this reality
Within protection scope with novel claims.
