The immobilization of the material filling-the loading and application method of the weighing instrument
1. Limit switch structure When building a material filling scale, the allowable offset is determined based on the weighing instrument and the installation accessories. Although this mounting accessory is self-centering, that is, self-calibrating, the limit switch is constructed to better ensure that the displacement of the filling does not exceed the larger allowable lateral displacement of the weighing device. Such as viewing angle blocker, or vulcanized rubber buffer. 2. Reverse direction ascent maintenance If the center of gravity of the material filling is located above the bearing point, and the damage caused by wind and other external forces cannot be removed, the material filling should be raised to maintain the organization in the opposite direction for the random falling or rising design plan. Must be designed for secondary maintenance or designed for maintenance in the opposite direction. For example, ascending maintenance can be accomplished in many ways by adding vertical spiral rods around the bearing point. The anchor bolt rod connected with the material grouting should be suspended in the air according to the buried hole on the loading plate. The maintenance gap is adjusted according to the two nuts located on the screw of the extruder. Depending on the size of the punched holes on the two loading boards, a larger lateral offset can also be defined. 3. The pendulum rod must be fixed with the pendulum rod when using the non-self-centering multi-ball rubber bearing or similar accessories. The specification and overall design of the pendulum rod should reasonably limit the unnecessary deviation of the material to be measured, such as the material filling, and reduce the hazards as much as possible in the precise measurement orientation. The ways to swing the rod are: 4. Steel wire rope compression: This plan is not harmful in the direction of gravity. 5. Anchor bolt support rod: In this plan, the externally threaded rod will only control the upward azimuth force of the bundle axis. In order to better be able to bundle the tubes in detail, two such support rods must be installed on one shaft. 6. Flat stick guide rod: The flat stick plan actually has extra force on the vertical position to cause weighing error. However, because the length of the flat rod is relatively long, even if the section size is relatively large, the extra bending force caused by it is relatively small. But in the case of calibration, the power of this accessory must also be paid more attention. 7. Pin swing rod: Under normal conditions, the extra force of the pin swing rod to the vertical position is not large. As everyone knows, if the swing rod is skewed in the horizontal direction, it is likely to cause the swing rod to be clamped. This causes sliding friction and increases the danger of extra force in the vertical position. Therefore, pay special attention to the precise positioning of the measured object during installation. The engine pull cylinders in many directions must have a relatively good relative position, and there must be no horizontal skew. 8. Anchor bolt swing rod with joint bearing: The anchor bolt swing rod with joint bearing is similar to the pin swing rod, but because the joint bearing can rotate at will in each direction, it can prevent the sliding friction of the pin swing rod. The harm. Therefore, in the case of installation, it is sufficient to level the pendulum rod. However, it must be noted that the lubrication of joint bearings must be done well, especially in the outdoor natural environment.
