Problems solved by technology

In this measurement method, it is necessary to go through the process of manual zero leveling and multiple manual tests, and there is a large cumulative error, and it is necessary to test the distance from the end of the meter stick to the axis of the stern shaft when the meter stick is horizontal. Difficulty and low measurement efficiency
The original measurement method has the characteristics of low precision, low efficiency, complex measurement and incapability of dynamic measurement, which can no longer meet the needs of modern production

Embodiment 1

[0013] Such as figure 1 Shown is Embodiment 1 of the present invention, an inclinometer, which includes a dial 1, a balance device, and a pointer 2 that is rotatably connected to the dial 1, and the pointer 2 keeps pointing to Invariably, there is a straight reference edge 3 on the dial 1 , and the scale lines on the dial 1 are evenly distributed along the circular arc with the connection point between the dial 1 and the pointer 2 as the center. The balance device includes a weight 4, a casing pipe 5, a threading pipe 6 and a suspension rope 7, the casing pipe 5 is fixedly arranged on the pointer 2, and the threading pipe 6 is fixed along the reference side 3 Set on the dial 1 , one end of the suspension rope 7 is connected to the weight 4 , and the other end passes through the casing pipe 5 and the threading pipe 6 sequentially. The suspension rope 7 adopted in this embodiment is a steel wire rope.

Embodiment 2

[0017] Such as figure 2 Shown is the second embodiment of the present invention, which is mainly different from the first embodiment in that: the balance device is a hanging weight 9 connected to the pointer 2 in rotation. Using the reference side 3 as a reference for inclination measurement, the hanging weight 9 can be connected to the pointer 2 through a rope, or directly connected to the pointer 2 through a pin.

[0018] The inclination measuring instrument can directly read the inclination angle of the measured shaft, simplifies the process of measuring the inclination angle, and thus has the characteristics of convenient measurement, high precision and dynamic measurement. In addition, the dial 1 and the pointer 2 of the inclinometer are both made of glass fiber reinforced plastic, so it has the characteristics of low cost and easy portability.

Abstract

The invention discloses a dip meter and aims to provide the dip meter which is capable of conveniently and dynamically measuring a shafting dip angle and is high in test accuracy. The dip meter comprises a dial (1), a balancing device and a pointer (2), wherein the pointer (2) is rotatably connected with the dial (1); the pointing direction of the pointer (2) remains unchanged under the action of the balancing device; a straight reference edge (3) is arranged on the dial (1); scale lines on the dial (1) are uniformly distributed along a circular arc which takes a connection point of the dial (1) and the pointer (2) as the center of a circle. During measurement, the dial (1) is rotated to enable the reference edge (3) to be parallel to a measured object, and a dig angle of the measured object can be obtained according to the reading of the pointer (2). The dip meter is mainly applied to the field of testing of ship shafting dip angles.

Description

technical field [0001] The invention relates to an inclinometer. Background technique [0002] In the marine field, in order to ensure the installation accuracy of shafting parts such as the stern shaft, it is often necessary to test the inclination angle of the stern shaft. The traditional method of measuring the stern shaft is: align the head end of a 1-meter ruler with a spirit level with one end of the stern shaft, then use a tape measure to measure the vertical distance from the end of the ruler to the axis of the stern shaft, and then use trigonometric functions to calculate the inclination angle of the stern shaft . In this measurement method, it is necessary to go through the process of manual zero leveling and multiple manual tests, and there is a large cumulative error, and it is necessary to test the distance from the end of the meter stick to the axis of the stern shaft when the meter stick is horizontal. It is difficult and the measurement efficiency is low. ...
