It can be a proximity switch assembly and an induction sheet. The induction sheet is arranged on the runner 2, the proximity switch assembly is arranged below the induction sheet, and the number of turns of the friction member 3 is recorded when the in...

Embodiment 2

[0132] Example 2, combined with Figure 8-14 , the difference between this embodiment and embodiment 1 is that this embodiment also includes:

[0133] A support 6; a rotating shaft 7, which is rotated and installed on the support 6; a pulley 8, which is installed on the rotating shaft 7; a belt 9, which is used to be installed on the meter wheel of the meter counter A, On the pulley 8; a rotating part 10 is used to drive the rotating shaft 7 to rotate, and the rotating part 10 can be a motor, so that the output shaft of the motor is connected with the rotating shaft 7 to drive the rotating shaft 7 to rotate; a second circle The number detection assembly 11 is used to detect the number of turns of the belt 9; it can be existing equipment, and can refer to the first number of turns detection assembly.

[0134] The friction member 3 is in line contact with the meter wheel of the meter counter A. In order to simulate different application scenarios of meter counter A. The frict...

Embodiment 3

[0141] Example 3, combined with Figure 15 , the present embodiment discloses a mechanical meter counter inspection method, comprising:

[0142] Step S00: installing the first friction member on the running wheel, and making the first friction member contact the first meter counting wheel of the meter counter.

[0143] Step S01: Fix the meter counter with a clamp.

[0144] Step S02: Using the power part to drive the runner to rotate.

[0145] Step S03: Calculate the rotation number S1 of the first friction member by using the first rotation detection component.

[0146] Step S04: The reading on the meter counter is P1.

[0147] Step S05: The error of the meter counter is: θ1=(P1-P2) / P2, wherein, the P2=S1*2πr 1 , r 1 is the distance between the contact point between the first friction member and the first meter wheel of the meter counter and the rotation center of the running wheel.

[0148] Use the friction parts to drive the first meter counter wheel to rotate, simulat...

Abstract

The invention discloses a mechanical meter counter inspection device comprising a clamp used for clamping a meter counter; a rotating wheel; the friction piece is arranged on the rotating wheel, and the friction piece is used for being in contact with a meter counting wheel of the meter counter; the power part is used for driving the rotating wheel to rotate; and the first turn number detection assembly is used for detecting the number of turns of rotation of the friction piece. The friction piece is detachably connected with the rotating wheel; the friction pieces at least comprise the first friction piece and the second friction piece, the roughness of the first friction piece is different from that of the second friction piece, the first friction piece and the second friction piece can be used for conducting error testing on the first meter counting wheel and the second meter counting wheel of the meter counter, then the first meter counting wheel and the second meter counting wheel are averaged, and therefore it is guaranteed that the testing error is accurate.

Description

technical field [0001] The invention relates to the technical field of meter counter maintenance, in particular to a mechanical meter counter inspection device. Background technique [0002] A meter counter is a widely used length measuring instrument. The meter counter generally includes a rotating shaft, two meter counting wheels installed at both ends of the rotating shaft, and a meter counting assembly installed on the rotating shaft. [0003] The measurement accuracy of the meter counter is very important, and it needs to be checked from time to time during use. [0004] In the Chinese patent application number: CN201410438754.5, a steel wire rope accurate meter counting device is disclosed, which includes an upper crimping wheel and a lower crimping wheel. There is a meter counting wheel in the middle of the wheel, and another pressing wheel is arranged above the contact surface between the meter counting wheel and the steel wire rope. The wire passing wheel presses t...
