Description
Technical field
The utility model relates to the tension equipment on a kind of single-chain type conveyer, particularly a kind of tightening device for single-chain type conveyer.
Background technology
Tightening device is for adjusting the device of distance between the delivery rolls such as load-transfer device, steel rope or scraper chain or transmission sprocket wheel etc.; On single-chain type conveyer, commonly use spiral tightening device, be used for regulating the distance of its tailing axle and driving chain wheel, simultaneously the tensioning degree of adjusting chain; For traditional spiral tightening device, when it is arranged on, there are two problems while using on single-chain type conveyer: the one, install inconvenient, the problems such as easily occurring skew, overbalance that is connected of pipe link and conveyer tailing axle; The 2nd, screw rod is difficult to adjust, because for traditional spiral tightening device, it regulates is conventionally all to realize by turning the nut on screw rod top, due to the small volume of nut own, very inconvenient while screwing, and period of service when long easily because there is the phenomenon that cannot turn in surface abrasion.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of easy installation and regulates more convenient, the tightening device of single-chain type conveyer efficiently.
The utility model is to solve the problems of the technologies described above adopted technical scheme to be: a kind of tightening device for single-chain type conveyer, comprise screw rod, hold-doun nut, adjusting lever, spring, fixed mount, and pipe link, screw rod runs through fixed mount, the front end of screw rod is provided with hold-doun nut, on screw rod, near bolt of rear end plate place, be provided with screw thread, adjusting lever be provided with screw rod on the corresponding tapped bore of screw thread, and be screwed on screw rod by tapped bore, spring housing is on screw rod and be located between fixed mount and adjusting lever, the end of screw rod is connected with pipe link, described adjusting lever is elongated rod shape, between described screw rod and pipe link, be provided with branched shaft, screw rod is connected with the middle part of branched shaft, the two ends of branched shaft are respectively equipped with pipe link.
In the utility model, fixed mount needs to be fixed in the frame of single-chain type conveyer in use, and pipe link is connected with the tailing axle of line-shifting machine, can adjust screw rod by turn adjust bar in use, be about to screw rod and pull to front end from fixed mount end, meanwhile, screw rod drives branched shaft and then drives pipe link to pull the tailing axle of line-shifting machine, realizes tensioning function; Owing to being elongated rod shape by screw rod, make its easier manual regulation, be convenient to fast adjust.
As optimum selection, described spring is fixed on fixed mount near one end of fixed mount, avoids spring to occur the faults such as loosening.
For the tapped bore on above-mentioned adjusting lever, can similarly be located at as conventional nut the middle part of adjusting lever, but also tapped bore can be arranged on to the end of adjusting lever, when being arranged on the end of adjusting lever, when screwing adjusting lever, because pivot point is positioned at the middle part of adjusting lever, this has just obviously increased moment of rotation, makes more laborsaving convenience when turn adjusting lever.
Described screw rod is connected with the middle part of branched shaft, and the two ends of branched shaft are connected with respectively pipe link, and pipe link is provided with for being fixed in the axis hole in line-shifting machine frame, for being fixedly connected with of single-chain type conveyer tailing axle.
Beneficial effect: a kind of tightening device for single-chain type conveyer of the utility model, the adjusting lever of reconciling tightening device is arranged to elongated rod shape, compare with traditional tightening device, adopt above-mentioned adjusting lever to make the adjusting of tightening device more easily laborsaving, screw rod is connected with branched shaft, the end of branched shaft arranges two pipe links, and tightening device is more easily installed on the tailing axle of conveyer, makes that the combination of tightening device and tailing axle is more convenient and stability is better.
