CN202101813U - Special sensor for weight and center of gravity measurement of large part - Google Patents

Abstract

The utility model relates to a special sensor for weight and center of gravity measurement of a large part. The special sensor comprises a contact-type sensor and a lifting jack, wherein the lower part of the contact-type sensor is flexibly connected with the lifting jack, and the top end of the sensor is in contact with the large part under test. The special sensor is not only simple in structure but is also not constrained by the environment factors such as site, and the like, and is convenient to maintain and verify. Meanwhile, the measurement of weight and center of gravity of the large part can be ensured and carried out safely, and the work efficiency is increased while the precision is ensured.

Description

The heavy parts weight center of gravity is measured sensor special

Technical field

The utility model relates to a kind of heavy parts weight center of gravity and measures sensor special, is applicable to the heavy parts that can jack-up, belongs to a kind of structural design field of load transducer.

Background technology

All the time, the weight of a part of heavy parts and center of gravity measurement all are to adopt following two kinds of methods.

1) on-ground weigher is installed in factory building, heavy parts is drawn on the on-ground weigher, then with after heavy parts jack-up and the frame level, the supported weight of each lifting jack of weighing is calculated gross weight and center of gravity then respectively.This kind method needs the special-purpose heavy parts factory building of weighing, the on-ground weigher that underground installation is huge, and the expense of factory building and on-ground weigher is all very high; Before and after weighing, all need move heavy parts, workload is big; On-ground weigher is not because removable; Calibration, calibrating, maintenance all must be carried out to the scene, and receive limitation of field condition, and be very inconvenient.

2) with lifting jack with heavy parts jack-up, be placed under the heavy parts with packaged type dull and stereotyped title, again heavy parts is fallen, treat the heavy parts level after, each dull and stereotyped supported weight of claiming of weighing is calculated gross weight and center of gravity then respectively.Though this method is not limited by or not the place, because the dull and stereotyped size of claiming is limit, it is more convenient that this method is measured weight ratio; But the center of gravity measurement existing problems are: owing to behind each jack-up heavy parts, again heavy parts is put into flat board and deserves to be called, heavy parts is difficult to level-off; Can only test one after another; Sometimes a horizontal adjustment needs the jack-up heavy parts 7 to 8 times, and workload is very big, and the work period is also long.

Summary of the invention

The technical matters that the utility model will solve provides a kind of heavy parts weight center of gravity and measures sensor special, and this sensor special is not only simple in structure, and does not receive environmental limit such as place, and working service and calibrating are convenient.Can guarantee simultaneously the measurement of heavy parts weight center of gravity, improve work efficiency in the time of not only security implementation, and assurance precision.

For overcoming the above problems; The concrete technical scheme of the utility model is following: a kind of heavy parts weight center of gravity is measured sensor special; Comprise touch sensor and lifting jack, the underside of touch sensor connects lifting jack, and the top of sensor contacts with heavy parts to be measured.

This heavy parts weight center of gravity is measured sensor special and is selected for use sturdy and durablely, and the sensor that the dependable performance precision is high is used to be installed in lifting jack, thereby does not receive environmental limit such as place, and working service and calibrating are convenient.Can guarantee simultaneously the measurement of heavy parts weight center of gravity, improve work efficiency in the time of not only security implementation, and assurance precision.

Description of drawings

Fig. 1 measures the sensor special structural representation for the heavy parts weight center of gravity.

Schematic layout pattern when Fig. 2 measures for adopting the heavy parts weight center of gravity to measure sensor special.

Embodiment

As shown in Figure 1, a kind of heavy parts weight center of gravity is measured sensor special, comprises touch sensor 1 and lifting jack 2, and the underside of touch sensor 1 connects lifting jack 2, and the top of sensor 1 contacts with heavy parts 3 to be measured.

The heavy parts weight center of gravity is measured the measuring method of sensor special to heavy parts, may further comprise the steps:

1) factory building with sealing is the test site, and ground is smooth;

2) sensor special is connected with corresponding test instrumentation, carries out zero clearing after the energising;

3) according to the horizontal situation under the heavy parts laying state, with three lifting jack that have sensor special simultaneously with heavy parts jack-up, three lifting jack distributions triangular in shape, as shown in Figure 2;

4) slowly adjust lifting jack, make heavy parts laterally, vertical equity;

5) after the heavy parts level, the data of record on the test instrumentation are carried out the calculating of weight and center under the specified states.

Claims (1)

1. a heavy parts weight center of gravity is measured sensor special; It is characterized in that: comprise touch sensor (1) and lifting jack (2); The underside of touch sensor (1) connects lifting jack (2), and the top of sensor (1) contacts with heavy parts to be measured (3).
