Description
Technical field
The present invention relates to a kind of dynamic single-rail balance, belong 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 purpose of the present invention provides, and alleviates operative employee's labour intensity and the dynamic single-rail balance of increasing work efficiency.
The present invention 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, two above LOAD CELLS, carrier and motor and suspension rod conveying mechanism, described support is framed structure, being positioned at support one side has its upper bracket of carrier of side opening and undersetting and extends to the top and bottom of support in the position respectively, one side of each LOAD CELLS is connected with support, the other end is connected with the upper bracket of carrier, the signal output part of each LOAD CELLS is connected with the input end of terminal box by signal cable, the outside of carrier is equipped with web joint, 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 and carrier chain and supporting wheel, case is installed on the undersetting of 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, be installed in being meshed on the case, and on the undersetting of carrier or case both sides are provided with the notch that is connected with the transition seat by movable sprocket and carrier chain.
The present invention adopts frame bracket, rack-mount with two with LOAD CELLS, 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 can be passed to equably 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 present invention can guarantee 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 carrying streamline to be used for Weighing is transformed.The present invention is provided with the notch that is connected with the transition seat on the undersetting of carrier, conveniently be connected with the transition seat, and suspension rod is smoothly moved on conveying track and carrier chain.
