Specific embodiment
Present invention will be described in further detail below with reference to the accompanying drawings, described to be explanation of the invention rather than limit
It is fixed.
As shown in Figure 1, a kind of mechanical horizontal measuring instrument, including shell 1, divide pointer 3, degree pointer 5, shot 9, degree pointer
Axis 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 divide pointer
One end of 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 fixed on degree needle pivot 11
The end of degree of being mounted on needle pivot 11, and it is located at the outside of cover board 7, degree of being provided with dial 6 on cover board 7 spends the finger of dial 6
It is ± 90 ° that demonstration, which is enclosed,.Degree pointer gear 10 and shot 9 are located at the inside of shell 1.Shot 9 is solid by swing rod and degree needle pivot 11
Even, it is 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
11 drives degree pointer 5 of needle pivot and the degree rotation of pointer gear 10 are spent in dynamic degree needle pivot rotation, and spend pointer gear 10 further through
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
Drive divides pointer gear 15 to rotate, and divides pointer gear 15 by dividing the drive of pointer driving shaft 16 that pointer internal gear 17 is divided to rotate, point
Pointer internal gear 17 divides pointer 3 to rotate together to drive, and 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, be exactly rotate 60 °, if feedback to being exactly 60' on 4, to realize dividing for horizontal measuring instrument
Class precision.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 consistent
's.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.
