Abstract

The utility model relates to a weights load-on and load-off device in the on-site calibration system used for a sensor or an electronic weigher in the standard device of the liquid flow-rate weighting method. The utility model is composed of an oblique split mechanism, a driving mechanism, and a lifting mechanism; the oblique split mechanism is connected with the driving mechanism by a connecting component; the driving mechanism can push the oblique split to do the translation motion; the lifting mechanism arranged on the oblique surface of the oblique split can do the rectilinear motion from top to bottom; therefore, the utility model can realize the weights load-on and load-off operation. Because the utility model makes use of the oblique split, the lifting capacity of the device is enlarged and the device can realize the self-locked operation. When the utility model weighs and calibrates, the repeatability and the stability of the utility model is enhanced.

Description

Oblique split type counterweight loading and unloading device

The counterweight that the utility model relates in a kind of on-site proving system that is used for fluid flow weight method standard set-up sensor or electronic scales loads and discharge mechanism.

In similar standard set-up, often adopted cylinder that counterweight is directly pushed up or puts down to the load or unload of counterweight, its shortcoming is in the past:

1, for promoting counterweight, cylinder dimensions are relatively large.

2, to promote counterweight reposefully, comparatively strict to the installation requirement of cylinder.

3, counterweight loads, unloading comes in the return motion, and the geometric center of be hard to keep cylinder and counterweight is consistent always, and this just brings certain influence to correctly loading and unloading counterweight and system stable.

The utility model purpose provides the compact load-carrying capacity of a kind of physical dimension big, energy self-locking, action repeatability and the oblique split type counterweight loading and unloading device that has good stability.

For this purpose, the technical solution of the utility model is: it by tiltedly split, driving mechanism, elevating mechanism form, tiltedly split by link and be connected with driving mechanism, driving mechanism promotes tiltedly to split to do translation motion, be arranged on the elevating mechanism moving linearly up and down on the inclined-plane of tiltedly splitting, thereby realize the loading and the unloading of counterweight.

The utility model embodiment is described further in conjunction with the accompanying drawings.

Fig. 1 is the utility model structural representation,

Fig. 2 is the A-A sectional view of Fig. 1;

Fig. 3 is the B-B sectional view of Fig. 1.

By shown in Figure 1, oblique split type counterweight loading and unloading device, it by tiltedly split 2, driving mechanism 4, elevating mechanism 1 form, driving mechanism can be with electronic, pneumatic or the driving mechanism that surges, present embodiment one cylinder is tiltedly split 2 and is connected with the cylinder piston push rod by link 3, by shown in Figure 3, link 3 is made up of fork shaft 22, pin 21 and split pin 23, by pin, fork shaft connects tiltedly to be split, and is locked by split pin.

By shown in Figure 2, elevating mechanism 4 is by casing 8, the bolt 10 of the work guiding of combining, pull bar 7 and roller 5 are formed, 8 liang of side hole 9 of casing, being placed on tiltedly splitting on the roller 62 passes hole 9 and does translation motion, tiltedly split down two rollers are set, tiltedly like this split two rollers below the top roller, make that tiltedly split can be reciprocating stably, each roller all has two bearings 14, be set on bearing pin 16 and the transverse axis 19, bearing is outside equipped with jump ring 18, bearing pin 16 two ends also are provided with jump ring 17,15 and are cover, and two bearings are equipped with roller housing 13 outward, make rectilinear motion stably up and down for making elevating mechanism, be equipped with copper sheathing 20 and last copper sheathing 12 and the pull bar 7 of hanging counterweight down respectively in casing 8 bottoms and loam cake 11, bolt 10 forms movingly, when cylinder promotes tiltedly to split when doing translation motion, makes to place the inclined-plane upper roller of tiltedly splitting to roll, drive bolt 10 and pull bar moving linearly about in the of 7, thus can add counterweight and unload counterweight.

Because the utility model has utilized tiltedly and has split, thereby to rising the counterweight of same weight, the cylinder volume can greatly reduce, the device load-carrying capacity is increased, and energy self-locking, utilize the translation stably tiltedly split and, make in weigh timing signal repeatability and stability and improve, for the long-term stable operation of electronic scales provides necessary guarantee by roller and guide blot and pull bar rectilinear motion stably.
