Abstract
The utility model discloses a high-strength heavy-load cranked link chain structure, comprising a plurality of cranked link chain sections which are connected in series to form a chain in a hinge pair manner, wherein each cranked link chain section comprises two cranked links, a pin shaft and a sleeve; the improvement is that one or two ends of the pin shaft, which is/are matched with the cranked links, is/are cylinder(s) with at least one cutting opening and protrude(s) out of the cranked links; a suitable rotation stopping block is arranged at the matching position of the cranked links; and the rotation stopping block and cranked link round holes form connection holes suitable for the pin shaft. According to the high-strength heavy-load cranked link chain structure provided by the utility model, the cylinder with the cutting opening is arranged at each end of the pin shaft, which is matched with the cranked link, so that influence on the chain using quality caused by the relative rotation between the pin shaft and the cranked links can be effectively prevented through the matching with the rotation stopping block.
Description
Technical field
The utility model relates to a kind of extraordinary conveying or Transmitted chains, the spacing cranked link chain structure of especially a kind of high strength heavy duty.
Background technique
The spacing cranked link chain chain of existing high strength heavy duty forms the bent plate chain link by two cranked plates, bearing pin, sleeves, the sleeve of the bearing pin of a bent plate chain link and another bent plate chain link is connected in series the formation flexible element with the form of hinges, and a plurality of bent plate chain links are connected in series chain of formation with the form of hinges.Between the bearing pin of this kind cranked link chain and the carrier bar by many reasons so that the chain plate hole increases, produce relative rotation between bearing pin and the carrier bar, affect the chain service property (quality).
Summary of the invention
The problem that the utility model in use exists for solving prior art provides to prevent the heavily loaded spacing cranked link chain structure of the high strength that produces relative rotation between bearing pin and the carrier bar.
The technological scheme that the utility model solves existing issue is: the spacing cranked link chain structure of high strength heavy duty, comprise some bent plate chain links that consist of chain with the form serial connection of hinges, described bent plate chain link comprises two cranked plates, bearing pin, sleeve, as improvement, the one or both ends that described bearing pin cooperates with cranked plate are the cylindrical body that is provided with at least one otch, and protrude from cranked plate, described cranked plate cooperation place is provided with the resistance switch block that adapts, and described resistance switch block and cranked plate circular hole consist of the attachment hole that adapts with bearing pin.
As further improvement, the end that described bearing pin cooperates with cranked plate is the cylindrical body that is provided with a kerf, roughly becomes " D " shape, and protrudes from cranked plate, be welded with the resistance switch block on the described cranked plate, described resistance switch block and cranked plate circular hole consist of " D " shape attachment hole that adapts with bearing pin.
The utility model compared with prior art, its beneficial effect is to be set to cylindrical body with otch by bearing pin and cranked plate abutting end place, by matching with the resistance switch block, can effectively prevent from producing relative rotation between bearing pin and the carrier bar, affect the chain service property (quality).
