Description

Lower suspension mechanism for weight volume measurement

Technical Field

The invention relates to the field of metering, in particular to a lower suspension mechanism for measuring the volume of a weight.

Background

At present, the weight is mostly measured by a liquid static pressure method, namely a measuring method taking liquid density as a reference, and the volume of the weight is calculated by buoyancy force of the measured weight in liquid. Require the weight to place on mass balance appearance central reference line when the weight is measured, if balancing unit has taken place the skew during measurement, directly can influence measuring accuracy, at present most measuring device adopt hang down the balance dish through the couple and hang under the mass comparator, and this kind of couple is connected and is made the offset of measuring central point easily, and the equilibrium is not good. The invention provides a lower suspension mechanism for weight volume measurement, which solves the technical problem.

Disclosure of Invention

Aiming at the defects in the prior art, the invention provides a lower suspension mechanism for weight volume measurement.

The invention is realized by the following technical scheme:

the utility model provides a hang mechanism down for weight volume when survey which characterized in that, includes mass comparator response scale dish, response connection piece I, response connection piece II, rack and gyro wheel.

The bilateral symmetry of quality comparator response scale has response connection piece I and response connection piece II form similar shoulder pole structure, and at the both ends of response connection piece I and the hollow rack of response connection piece II's lower extreme difference fixed connection "U" type, semicircular standing groove has been seted up respectively on two frame plates of rack, and the gyro wheel comprises gyro wheel body and gyro wheel neck, and the gyro wheel neck is placed to the standing groove, and the gyro wheel body is located the well kenozooecium of rack.

Further, this lower suspension mechanism still includes backup pad, control lever, handle, bearing wheel, fixed block I and fixed block II, quality comparator lower plate.

The mass comparator lower plate one end is located the long limit end of two "L" shape backup pads that rack both sides and symmetry set up through two fixed block I fixed connection, and two fixed block II of fixed connection on the lower plate other end of mass comparator, fixed connection control lever between two fixed block II are provided with the carrier wheel of two water droplet forms on the control lever, and the minor face and the long limit turning portion of two "L" shape backup pads are placed on the carrier wheel. Support grooves are respectively formed in the two support plates and in the same axis position with the placing groove, the roller necks can be placed in the support grooves, and a handle is arranged at one end of the control rod.

Furthermore, the roller body is detachably and vertically connected with a lower hanging scale pan through a suspension rod.

Compared with the prior art, the lower suspension mechanism has the following beneficial effects: the lower suspension mechanism of the shoulder pole structure provided by the invention has good balance, can keep the central point of the mass comparator unchanged in the largest range, reduces the introduction of unbalance loading of a measuring instrument, and simultaneously, because the support plate structure is arranged, when the lower suspension scale is not needed, the roller is lifted up by rotating the handle and separated from the placing frame, so that the dual-purpose machine is realized.

Detailed Description

The technical scheme of the invention is clearly and completely described below by combining specific embodiments. It is obvious that the described embodiments are only some of the embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 and 2, the lower suspension mechanism for weight volume measurement comprises a mass comparator induction scale pan 1, an induction connecting sheet I2, an induction connecting sheet II 21, a placing frame 3 and a roller 4.

The both sides symmetry of mass comparator response scale 1 is connected with response connection piece I2 and response connection piece II 21, forms similar shoulder pole structure, the lower extreme of response connection piece I2 and response connection piece II 21 respectively fixed connection "U" type hollow rack 3's both ends, semicircular standing groove 31 has been seted up respectively on the frame plate of rack 3, gyro wheel 4 comprises gyro wheel body 41 and gyro wheel neck 42, gyro wheel neck 42 is placed to standing groove 31, gyro wheel body 41 is located the well kenozooecium of rack 3. The roller body 41 is vertically detachably connected with a mass balancing device through a suspension rod 11.

The roller body 41 of the roller 4 is connected with the lower suspension scale through the suspension rod 11, after the weight is placed into the lower suspension scale, the roller 4 senses gravity, because the roller neck 42 of the roller 4 is placed on the placing rack 3, the two ends of the placing rack are connected with the sensing connecting sheet I2 and the sensing connecting sheet II 21, the sensing connecting sheet I2 and the sensing connecting sheet II 21 are connected with the sensing scale 1 of the mass comparator, so the sensing scale 1 of the mass comparator senses gravity signals, and mass data are obtained.

In this example, the lower suspension mechanism further comprises a support plate 5, a control rod 6, a handle 7, a bearing wheel 8, a fixing block I9 and a fixing block II 10. One end of a lower base plate 12 of the mass comparator is fixedly connected with long-edge ends 5 of two L-shaped supporting plates which are positioned at two sides of the placing rack 3 and symmetrically arranged through two fixing blocks I9, the other end of the lower base plate 12 of the mass comparator is fixedly connected with two fixing blocks II 10, a control rod 6 is fixedly connected between the two fixing blocks II 10, two water-drop-shaped bearing wheels 8 are arranged on the control rod 6, and short-edge corner parts and long-edge corner parts of the two L-shaped supporting plates 5 are placed on the bearing wheels 8; the two support plates 5 are respectively provided with a support groove 51 at the same axial position with the placing groove 31, the roller neck 42 can be placed in the support groove 51, and one end of the control rod 6 is provided with the handle 7.

When the lower suspension mechanism is used, the supporting groove 51 and the roller neck 42 are in a separated position and cannot bear the gravity of the roller 4, after the lower suspension mechanism is used, the bearing wheel 8 can be controlled to rotate through the handle 7, and the bearing wheel 8 is in an irregular water drop shape, so that the supporting plate 5 can be driven to rise or fall relative to the horizontal plane. The bearing wheel 8 can be rotated through the handle 7, so that the supporting plate 5 rises, and the supporting groove 51 drives the roller 4 to rise, thereby suspending the whole roller 4 in the placing frame 3. For convenience of use, the suspension rod 11 may be detachably attached to the roller body 41.
