Description

Dynamic single-rail balance

Technical field

The utility model relates to a kind of dynamic single-rail balance, belongs to single track electronic crane scale technical field.

Background technology

The single track electronic crane scale is commonly called as single-rail balance, is mounted on the suspended rail of carrying streamline, and the article that track is carried are weighed.The single track electronic crane scale is mainly by upper bracket at present, LOAD CELLS, lower carriage and pull bar constitute, lower carriage is connected by pull bar with upper bracket, LOAD CELLS then is connected on upper bracket and the pedestal, pedestal is connected on the spandrel girder, spandrel girder only no longer bears weight as a supporting member for this reason, because being connected the track of weighing of lower carriage is to separate with conveying track, therefore after weight slips into the track of weighing by suspension hook, the weight of object is passed to by lower carriage and upper bracket it is deformed, and exports corresponding electric signal by resistance strain gage and realizes weighing.But the single-rail balance of said structure, must be claimed article can the mistake manual type to shift onto on the track of weighing weighs, need again after weighing manually article to be released the track of weighing, in the operation, need two people to lay respectively at the both sides of the track of weighing, because claimed that article can not move at the track of weighing automatically, operative employee's labour intensity is big, and the work efficiency that also influences.

Summary of the invention

It is a kind of rational in infrastructure that the purpose of this utility model provides, the dynamic single-rail balance that alleviates operative employee's labour intensity and increase work efficiency.

The utility model is that the technical scheme that achieves the above object is: a kind of dynamic single-rail balance, it is characterized in that: comprise support, LOAD CELLS, carrier and motor and suspension rod conveying mechanism, described support is framed structure, its upper bracket of carrier that is positioned at support one side is connected with support by LOAD CELLS, the signal output part of LOAD CELLS is connected with the input end of terminal box by signal cable, carrier is equipped with web joint at homonymy, motor is installed on the web joint, and the output terminal of motor passes through follower, driving-chain or driving-belt are connected with driving wheel on the suspension rod conveying mechanism; Described suspension rod conveying mechanism comprises case, driving wheel, by movable sprocket, carrier chain and supporting wheel, case is installed on the undersetting of each carrier, two supporting wheels are installed in the both sides of case respectively, carrier chain is sleeved on two supporting wheels, driving wheel is connected with passive sprocket coaxiality, is installed in being meshed by movable sprocket and carrier chain on the case.

The utility model adopts frame bracket, can LOAD CELLS is rack-mount, be connected with support with separately LOAD CELLS and be positioned at its upper bracket of carrier of support one side, its undersetting of carrier is connected with the suspension rod conveying mechanism again, therefore after weight enters the suspension rod conveying mechanism by suspension hook from the conveying track on the streamline, by the suspension rod conveying mechanism in the process of suspension rod automatic transport, the weight of object that hangs on the suspension rod is passed to by carrier makes it deform on the LOAD CELLS, exporting corresponding electric signal by resistance strain gage realizes weighing, can measure the article of streamline quickly and accurately, because unmanned guard, alleviated operative employee's labour intensity significantly, work efficiency improves more than 200%.The utility model can be guaranteed weighing precision by being installed in the motor on the carrier and driving the suspension rod conveying mechanism by corresponding gear train, and is simple and reasonable, is convenient to the existing suspended rail of streamline of carrying is transformed.
