Abstract
The invention discloses a kind of standard test weight, the primary structure feature is that below, this standard test weight front and below, side are provided with each two of symmetrical grooves, above four jiaos be arranged with groove, groove respectively is fixed with the spreader that is used for steady handling, upper central is provided with rectangular boss, and bottom surface central authorities are provided with the rectangular recess that cooperates with rectangular boss.This standard test weight material, quality, class of accuracy all meet the requirement of JJG99-2006 " counterweight " national metrological verification regulations, its easy to use, transportation safety, and stably multilayer stacks loading and unloading.Simultaneously available fork truck or crane four directions be to loading and unloading, and putting than the zonule, safe.
Description
Technical field
The present invention relates to a kind of counterweight, refer in particular to a kind of class of accuracy that is used to examine and determine
The standard test weight of level and following large-scale weighing machine.
Background technology
The counterweight profile of tradition calibrating large-scale weighing machine is a rectangle or cylindrical, has only the two sides fork pockets, does not have top convex surface and following groove.Since above have only two grooves and the spreader of symmetry, when handling, be difficult to reach steadily and move, stack and transport also dangerous, need join auxiliary ruggedized equipment.This class counterweight majority can not be carried with fork truck, and the perform region requires big, inefficiency.Overcome above-mentioned shortcoming so development is a kind of, handling is steady, and the counterweight that stacks with transportation safety is necessary.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of standard test weight, and this standard test weight has increased fork pockets that cooperates with fork truck and the groove spreader that cooperates handling again on traditional rectangle counterweight basis, more to meet stacking and the transportation safety requirement of counterweight.
Technical matters of the present invention is solved by following scheme: standard test weight, profile is a rectangular parallelepiped, fork pockets is established on the two sides, groove and spreader that symmetry is arranged above, positive central authorities are provided with counterweight and adjust the chamber, it is characterized in that: described fork pockets is the groove of each two symmetry of positive below and below, side, above four jiaos be arranged with described groove, described groove respectively is fixed with the described spreader that is used for steady handling, and upper central is provided with rectangular boss, and bottom surface central authorities are provided with the rectangular recess that cooperates with rectangular boss.
The present invention also comprises following scheme: the rectangular recess of the rectangular boss of described upper central and bottom surface central authorities is the inclination angle.
Advantage of the present invention is: this standard test weight material, quality, class of accuracy all meet the requirement of JJG99-2006 " counterweight " national metrological verification regulations, and its easy to use, transportation safety can be increased work efficiency, but and multilayer stack loading and unloading.Simultaneously available fork truck or crane four directions be to loading and unloading, and can put than the zonule, and the rectangle convex surface on the big case of groove fit automobile of bottom surface design no longer needs any reinforcing in transit, and is safe.

Fig. 2 is the right view of this standard test weight
Fig. 3 is that figure cuts open in the office of overlooking of this standard test weight
Fig. 4 is the upward view of this standard test weight
Embodiment
Below in conjunction with accompanying drawing for an embodiment: as Fig. 1-shown in Figure 4, this standard test weight is mainly used in the calibrating class of accuracy
Level and following large-scale weighing machine.Rectangular parallelepiped physical dimension is 850 * 600 * 380 (mm).
As shown in Figure 1, the positive central authorities of standard test weight are provided with and adjust chamber 1, are used for certified weights and carry out counterweight when overproof.As shown in Figure 1 and Figure 2, positive below and below, side are provided with the groove 2,3 each two of symmetry, make things convenient for fork truck to carry.As shown in Figure 3, above four jiaos be arranged with groove 4, groove 4 respectively is fixed with the spreader 5 that is used for steady handling.As Fig. 1, Fig. 2, shown in Figure 3, upper central is provided with rectangle boss 6.As Fig. 1, shown in Figure 4, bottom surface central authorities are provided with rectangular recess 7.Rectangle boss 6 and rectangular recess 7 are the inclination angle.When up and down two standard test weights stacked, the rectangular recess 7 of last standard test weight bottom surface just in time cooperated with following rectangle boss 6 above the standard test weight and stacks, and increases its stability.
Claims (2)
1, standard test weight, profile is a rectangular parallelepiped, fork pockets is established on the two sides, groove and spreader that symmetry is arranged above, positive central authorities are provided with counterweight and adjust the chamber, it is characterized in that: described fork pockets is the groove of each two symmetry of positive below and below, side, above four jiaos be arranged with described groove, described groove respectively is fixed with the described spreader that is used for steady handling, and upper central is provided with rectangular boss, and bottom surface central authorities are provided with the rectangular recess that cooperates with rectangular boss.
