The invention has the beneficial effects as follows: the invention solves the difficult problem that pendulum cannot be weighed, achieve the correct amount to pendulum.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described:
Fig. 1 is that part of the present invention cuts open front view;
Fig. 2 is the A-A view of Fig. 1;
In figure: 1-base, 2-backstay, 3-lower connecting rod, 4-S type LOAD CELLS, 5-upper connecting rod, 6-are top, 7-weighing instrument, 8-abutment sleeve, 9-setting nut, 10-gathering sill, 11-trip bolt, 12-adjust screw, 13-spirit bubble.
Embodiment
As shown in Figure 1 and Figure 2, the present invention includes base 1, that backstay 2, lower connecting rod 3, S type LOAD CELLS 4 and S type LOAD CELLS top are arranged is top, base 1 is provided with levelling device, and backstay 2 adopts hollow structure, and the lower end of backstay 2 is fixedly connected on the middle part of base 1.The upper end of described backstay 2 and the junction of lower connecting rod 3 are provided with abutment sleeve 8, the upper end of described abutment sleeve 8 is placed on lower connecting rod 3, the lower end of described abutment sleeve 8 is fixedly connected with the upper end of backstay 2, the upper surface of described abutment sleeve 8 is also provided with setting nut 9, described setting nut 9 is threaded with the lower end of lower connecting rod 3, the inside of backstay 2 is stretched in the lower end of described lower connecting rod 3 through abutment sleeve 8, on lower connecting rod 3, correspondence arranges threaded part and is provided with a gathering sill 10 vertically, one side of the abutment sleeve 8 corresponding with gathering sill 10 is provided with a trip bolt 11, the end of trip bolt 11 stretches in the gathering sill 10 of setting on lower connecting rod 3 through abutment sleeve 8.Described S type LOAD CELLS 4 is arranged at the upper end of lower connecting rod 3, the upper connecting rod 5 that described S type LOAD CELLS 4 is arranged by its upper end is threadedly connected to top 6, the upper end of upper connecting rod 5 is provided with external thread, top 6 correspondences are provided with internal thread, what screw thread adopted herein is fine thread, and described S type sensor 4 connects a weighing instrument 7 by signal cable.
Described levelling device comprises and is arranged on four corners that on base 1 four adjustment screws 12 and a spirit bubble 13, four adjustment screws 12 are distributed in base 1.
When using of the present invention, first utilize the levelling device on base, the levelness of adjustment base.Adjustment screw is regulated, until bubble mediates in spirit bubble, to realize the leveling of base according to the situation of bubble in spirit bubble.Then by rotation to horizontal level wait claim pendulum be placed on top on, if the height of weighing instrument does not mate with the height of the pendulum being in horizontal level, need to weighing instrument carry out height adjustment.Point coarse adjustment and accurate adjustment two step is highly regulated to realize, first trip bolt is unscrewed during coarse adjustment, then setting nut is twisted, lower connecting rod is elevated, thus drive S type LOAD CELLS and top lifting, to complete the coarse adjustment of weighing instrument height, after coarse adjustment completes, tighten the position that lower connecting rod after coarse adjustment fixed by trip bolt, accurate adjustment is then by rotating the top fine adjustments realizing height.On the basis carrying out first two steps, just can read pendulum accurately from weighing instrument and to weigh value.
Except the technical characteristic described in above-mentioned instructions, be the known technology of those skilled in the art.
