The double-screw protective device is simple, compact and reasonable in structure. Difficulties in installation of the weighing sensor are effectively reduced, and the precision is guaranteed. Moreover, the weighing sensor is less likely to be violently impacted and damaged due to shake during transportation, and the service life and the precision of the weighing sensor are improved.
Description
Technical field
The utility model relates to a kind of weighing and sensing twin-screw protective device, specifically for the protection of LOAD CELLS, belongs to sensor technical field.
Background technology
In the work of engineering machinery mixing plant, characterisitic parameter is correct selected most important to the accuracy of feature batching in the weighing system, so LOAD CELLS is very important parts in the work of engineering machinery mixing plant.
In the installation and transportation process of large-scale computation weigh equipment, because the LOAD CELLS Rig up error, the fixing factor such as not in place of LOAD CELLS usually has influence on the precision of weighing in the transportation, LOAD CELLS even be damaged when serious.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of LOAD CELLS twin-screw protective device is provided, and can protect LOAD CELLS, avoids LOAD CELLS to receive that severe impact or overload affect its precision.
The technical scheme that provides according to the utility model; LOAD CELLS twin-screw protective device comprises and hangs runners, upper connecting base, suspension bracket, lower connecting base, LOAD CELLS, upper spherical plain bearing rod end, lower spherical plain bearing rod end, upper pin, lower bearing pin and weighing hopper; hang the runners lower end and connect upper connecting base, upper connecting base passes through upper pin) upper spherical plain bearing rod end is articulated and connected.Described upper spherical plain bearing rod end lower end connects LOAD CELLS, and the LOAD CELLS lower end connects lower spherical plain bearing rod end.Described lower spherical plain bearing rod end is by the lower bearing pin lower connecting base that is articulated and connected.Described lower connecting base is fixed on cradle sides.Described suspension bracket is fixed on the weighing hopper, it is characterized in that: also comprise the first stud bolt and the second stud bolt, described hanging passed through the first stud bolt and is connected the stud bolt connection between runners and the lower connecting base.
Is hanging on the runners by the first fastening nuts described the first stud bolt upper end.
The second fastening nuts is passed through on lower connecting base in described the first stud bolt lower end.
Is hanging on the runners by the 3rd fastening nuts described the second stud bolt upper end.
The 4th fastening nuts is passed through on lower connecting base in described the second stud bolt lower end.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Effectively reduce the LOAD CELLS difficulty is installed, to guarantee its precision; Be reduced in the transportation moderately gusty air and rock the infringement of the severe impact of LOAD CELLS, improve serviceable life and the precision of LOAD CELLS.
