Description
Technical field
The utility model relates to a kind of protective device of measuring weighing instrument, particularly relates to a kind of one ton of counterweight comparator device that stops.
Background technology
When weighing the tonnage counterweight, because of counterweight weight big, be difficult for placing in the scale pan, and existing method of putting counterweight can make counterweight when entering the scale pan or shifting out the scale pan, produce bigger impulsive force, large face plate and LOAD CELLS are impacted, not only influence the accuracy and the stability of weighing, also can damage measuring weighing instrument when serious.For this reason, people are for to protect weighing apparatus to do a large amount of work effectively, for example, publication number be CN2763783's " a kind of counterweight adds handler automatically ", it is made up of the column of band lower support piece and the counterweight holder frame of band upper support piece, and it is characterized in that: above-mentioned column and counterweight holder frame are formed the counterweight support; Counterweight is placed on the counterweight holder frame, frames shift moving with the counterweight holder.Publication number be CN2390192's " the weighing protective device of electronic balance (electronic scales) ", form by large face plate, support plate, LOAD CELLS, control handle and eccentric rod gear; Its eccentric rod gear comprises excentric shaft, upward connecting rod, strand connect point, lower link, rocking arm, rocking shaft, and it is characterized in that: a. excentric shaft has left and right two groups, totally 4 eccentric salient points; Two groups of excentric shafts connect point by last connecting rod by strand respectively and are connected with lower link, and lower link connects point by strand and is connected with the two ends of rocking arm, and the duty of rocking arm is regulated by rocking shaft by knob.B. eccentric rod gear is installed between the large face plate and LOAD CELLS of electronic balance (electronic scales), and knob is installed on electronic balance (electronic scales) the casing face.Though above-mentioned these technical schemes can play the certain protection effect to the metering balance, and are powerless to the situation that counterweight is heavier.
The utility model content
The purpose of this utility model is to overcome the prior art above shortcomings; solution in metering process because of this problem of stability of Weight gravity impact failure measuring weighing instrument; by improvement to existing measuring weighing instrument protective device structure; provide a kind of one ton of novel counterweight comparator device that stops; the utility model is simple in structure; reliable in action; in interpolation or taking-up counterweight process, can not impact to the weighing main body; thereby guaranteed the accuracy and the stability of measuring weighing instrument, also prolonged the serviceable life and the precision of measuring weighing instrument.
The technical scheme that the utility model provides is: this one ton of counterweight comparator device that stops, include motor, lifter, framework, crane, support column, the lifting tray and the scale pan, be characterized in that described framework is provided with crane, this crane upper end is provided with support column, support column is connected with lifting tray, described framework is provided with motor, this driven by motor crane also orders about crank and rotates, one end of this crank is hinged with the fixed mount that is fixed on the framework, one end of its other end and connecting rod is hinged, this crank also is connected with crane by rotating shaft, one end of the other end of connecting rod and another crank is hinged, the other end of another crank is connected with the wheel that can roll on framework, and another crank also is connected with crane by rotating shaft, and described base of frame also is provided with support foot and footing wheel.
Compared with prior art, the beneficial effects of the utility model are: simple in structure, motion is reliable, can not impact to the weighing main body in interpolation or taking-up counterweight process, thereby guaranteed the accuracy and the stability of measuring weighing instrument, also prolonged the serviceable life and the precision of measuring weighing instrument.
Description of drawings
The structural representation of the embodiment that Fig. 1 provides for the utility model;
Fig. 2 is the A-A cut-open view of Fig. 1;
Fig. 3 is the B-B cut-open view of Fig. 1.
Embodiment
As Fig. 1～shown in Figure 3, this one ton of counterweight comparator device that stops, include motor 1, lifter 2, framework 3, crane 4, support column 5, the lifting tray 6 and the scale pan 7, framework 3 is provided with crane 4, these crane 4 upper ends are provided with support column 5, support column 5 is connected with lifting tray 6, framework 3 is provided with motor 2, this motor 2 drives lifter 4 and orders about crank 8 and rotate, one end of this crank 8 is hinged with the fixed mount 10 that is fixed on the framework 3, one end of its other end and connecting rod 11 is hinged, this crank 8 also is connected with crane 4 by rotating shaft 9, one end of the other end of connecting rod 11 and another crank 12 is hinged, the other end of another crank 12 is connected with the wheel that can roll on framework 3, another crank 12 also is connected with crane 4 by rotating shaft 13, and described framework 3 bottoms also are provided with support foot 14 and footing wheel 15, and number in the figure 16 is supporting socles.
The course of work of the present utility model is as follows:
When hoisting, starter motor 1 is just changeing to hoist by lifter 2,12 rotations of crank 8 rotation drivening rods 11 throw cranks reach crane 4 and steadily rise synchronously, hold up lifting tray 6 by support column 5 and steadily rise, weight is held up from the scale pan 7, make the metering balance be in state to be weighed.
During decline, starter motor 1, descend by lifter 2 counter-rotatings, 12 rotations of crank 8 rotation pulling connecting rods 11 throw cranks, reaching crane 4 steadily descends synchronously, the lifting tray of holding by support column 56 steadily slowly descends, and from steadily putting to the scale pan 7, makes the metering balance be in the state of weighing on the weight in the lifting tray 6.
Because the scale pan 7 is located at the middle neutral gear place of the lifting tray 6 of frame-type, the scale pan 7 has certain interval with the edge of lifting tray 6, and therefore, lifting tray 6 sinks down into the below, plane of the scale pan 7 when not working, and rises during need of work again.
