Description

Technical Field

[0001] The utility model relates to the technical field of level measurement, in particular to a level accuracy measurement auxiliary tool. Background Art

[0002] When measuring the horizontal accuracy of the equipment, the liquid plate is usually placed on the upper surface of the equipment, and the collimating light tube is set up directly above the liquid plate through a bracket. The stable liquid in the liquid plate is used as the local horizontal reference, and the verticality of the collimating light tube is adjusted by using the angle difference between the emitted and received light, and then the horizontal accuracy of the equipment is measured by the collimating light tube.

[0003] At present, the main problems with the horizontal accuracy measurement of existing equipment are: because the measurement location of the equipment is fixed and there is a large convection of air above the measurement area, the liquid in the liquid tray cannot remain stable (that is, the horizontal reference of the liquid surface shakes), which results in personnel being able to roughly adjust the verticality of the collimating light tube according to the middle value of the reference shake, thereby affecting the accuracy of the equipment's horizontal accuracy measurement results; second, the liquid tray is placed on the equipment, and since the outer shell will have micro-frequency vibrations when the equipment is running, the liquid in the liquid tray will have micro-frequency fluctuations, affecting the stability of the liquid, thereby affecting the accuracy of the equipment's horizontal accuracy measurement results; third, due to the increase in temperature during equipment operation, the heat will be transferred to the liquid in the liquid tray, causing the viscosity and stability of the liquid to decrease, thereby affecting the accuracy of the equipment's horizontal accuracy measurement results; fourth, the horizontal accuracy measurement adopts a long-term averaging method to adjust the verticality of the collimating light tube, which is time-consuming, thereby affecting the accuracy of the equipment's horizontal accuracy measurement results; fifth, the liquid tray is placed on the equipment, and there is a safety risk that the liquid in the liquid tray will spill onto the equipment, causing the equipment performance to decline. Utility Model Content

[0004] In order to overcome the defects of the prior art that the liquid in the liquid pan is unstable, resulting in inaccurate measurement results and safety risks, the utility model provides a horizontal accuracy measurement auxiliary tool.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a horizontal precision measurement auxiliary tool, including a support frame, on which an upper turntable and a lower turntable are rotatably connected from top to bottom in sequence, the upper turntable is provided with an upper light-through hole, light-through glass and a visible upper fan ring hole, and the lower turntable includes a lower light-through hole, an annular disc support and a visible lower fan ring hole.

[0006] As a further improvement of the utility model, the support frame includes a support frame, a rotating shaft support is provided at the top center position of the support frame, and a plurality of support legs are evenly distributed at the bottom of the support frame.

[0007] As a further improvement of the utility model, a supporting foot is provided at the bottom of the supporting leg.

[0008] As a further improvement of the present invention, the supporting legs are telescopic supporting legs.

[0009] As a further improvement of the utility model, the light-transmitting glass is coated glass.

[0010] As a further improvement of the utility model, the upper turntable and the lower turntable are rotatably connected to the rotating shaft support through corresponding bearing seats respectively.

[0011] Compared with the prior art, the utility model has the beneficial effects: in this scheme, the liquid disc is placed in the annular disc holder on the lower turntable, and the upper turntable and the lower turntable are slowly rotated so that the collimating light tube, the light-transmitting glass, and the liquid disc are in the same straight line. The light-transmitting glass blocks air convection so that the liquid in the liquid disc is stabilized at the local horizontal plane. The collimating light tube is adjusted to be perpendicular to the local horizontal plane, and the upper turntable and the lower turntable are slowly rotated again so that the upper light-transmitting hole, the lower light-transmitting hole, and the collimating light tube are in the same straight line, thereby performing the horizontal accuracy measurement of the equipment, effectively solving the problem of inaccurate measurement results caused by the instability of the liquid in the liquid disc during the horizontal accuracy measurement of the equipment, reducing the measurement error of the equipment, shortening the measurement time of the equipment, and ensuring the safety of the equipment.

[0019] When in use, place the auxiliary tool on the equipment so that the auxiliary tool is roughly horizontal. The collimating light tube is set above the auxiliary tool through the bracket. Through the visible upper fan ring hole 33 on the upper turntable 3, the liquid plate is placed in the annular plate holder 22 on the lower turntable 2. The visible upper fan ring hole 33 serves to increase the field of view and the space for placing the liquid plate. The annular plate holder 22 acts as a limiter for the liquid plate when the lower turntable 2 rotates. Slowly rotate the upper turntable 3 and the lower turntable 2 so that the collimating light tube, the light-transmitting glass 32, and the liquid plate are in the same straight line. The light-transmitting glass 32 blocks air convection so that the liquid in the liquid plate is stable at the local horizontal plane. At this time, the collimating light tube can be adjusted to be perpendicular to the local horizontal plane. Slowly rotate the upper turntable 3 and the lower turntable 2 again so that the upper light-transmitting hole 31, the lower light-transmitting hole 21, and the collimating light tube are in the same straight line, so as to measure the horizontal accuracy of the equipment.

The supporting leg 13 is a retractable supporting leg to ensure the stability of the supporting leg 13 and the height of the auxiliary device is variable. The upper turntable 3 and the lower turntable 2 are rotatably connected to the rotating shaft support 11 through corresponding bearing seats 4 respectively.

[0021] The support leg 13 is made of a stainless steel hollow tube with a diameter of φ25mm. The height of the support leg 13 is H430mm. The distance between two adjacent support legs 13 is L430mm. The upper turntable 3 and the lower turntable 2 are 8mm thick stainless steel plates with a diameter of φ550mm. The upper turntable 3 and the lower turntable 2 are each surrounded by 15mm, thereby improving the rigidity of the turntable.
