Abstract
The utility model provides a rolling tensioning mechanism for a chain conveyer. According to the rolling tensioning mechanism, during tensioning, sliding friction is replaced by rolling friction, so that the acting force during adjustment is reduced, fault-free tensioning of the chain conveyer under an execrable working condition is realized, the equipment use requirement is met, the failure rate is reduced, and the maintenance cost is lowered. The rolling tensioning mechanism comprises a conveying chain, wherein the tail end of the conveying chain is sleeved on a rotating shaft; two ends of the rotating shaft are respectively supported on a bearing base. The rolling tensioning mechanism is characterized in that two sides of the bottom of the bearing base are respectively fastened with a mounting plate; the middle parts of two ends of each of the mounting plates are respectively provided with a roller wheel; the roller wheels are supported on a limit guide rail at the bottom; the upper part of the bearing base is fastened and connected with one end of a regulating screw rod; the other end of the regulating screw rod penetrates through a vertical plate of a bracket and then is sleeved with a nut; an automatic spring is arranged between the nut and the outer side surface of the vertical plate of the bracket and sleeved on the regulating screw rod; the bottom of the bearing base is convexly provided with a limit bump.
Description
Technical field
The utility model relates to the technical field of structures of chain-linked conveyer, is specially a kind of chain-linked conveyer rolling stretching device.
Background technology
Chain-linked conveyer is widely used in the industries such as metallurgy, electric power, chemical industry, for delivery of raw material, dust collection conveying, batching etc., in equipment running process, chain can extend because wearing and tearing, special operation condition, self stretch etc. produce, and chain-linked conveyer all adopts bearing seat or closing plate to be played and made up elongation and play chain tension effect by helical screw.But the situation that this stretching device there will be in the situation that equipment is carried for high temperature and long distance is stuck, cannot tensioning, to make equipment because of chain too pine cannot normally work and occur chain rupture phenomenon.
Summary of the invention
For existing above-mentioned defect, the utility model provides a kind of chain-linked conveyer rolling stretching device, cliding friction when it changes tensioning is friction of rolling, application force while reducing to adjust, realize chain-linked conveyer trouble free tensioning under bad working environments, meet equipment operating needs, reduce fault rate, reduce maintenance cost.
A kind of chain-linked conveyer rolling stretching device, its technical scheme is such: it comprises conveyer chain, the end of described conveyer chain is set in rotating shaft, the two ends of described rotating shaft are supported on respectively bearing seat, it is characterized in that: the two bottom sides of described bearing seat is fastened with respectively adapter plate, the midway location at the two ends of described adapter plate is respectively arranged with roller, described roller wheel bearing is in the limit guide rail of bottom, the top of described bearing seat is fastenedly connected with the one end that regulates screw mandrel, the other end of described adjusting screw mandrel is set with nut after running through support riser, between the lateral surface of described nut and described support riser, be provided with auto spring, described auto spring is set in described adjusting screw mandrel, protruding limited location projection under the bottom of described bearing seat, described limit guide rail is provided with warning device near the position epirelief of described support riser, the front end of described spacing block set faces described warning device.
It is further characterized in that: guiding collar is equipped with in the inner side of described nut, the arranged outside of described support riser has back plate, described adjusting screw mandrel runs through described back plate, described guiding collar is set in described adjusting screw mandrel, the two ends of described auto spring are mounted on respectively the inner side of described back plate outside, guiding collar, and described nut is close to the outside of described guiding collar.
Adopt after structure of the present utility model, the elongation of conveyer chain in course of conveying strained conveyer chain along limit guide rail motion and by auto spring along adjusting screw mandrel by the roller of the bearing seat of end, realize automatic chain tensioning, owing to being friction of rolling between roller and limit guide rail, application force while reducing to adjust, realizes chain-linked conveyer trouble free tensioning under bad working environments; And in the time of spacing block set laminating warning device, alerting signal is sent in the position that reaches capacity, avoid, because of pernicious situations such as sideslip that chain slack produces, blocking, chain ruptures, guaranteeing the normal operation of integral device, greatly reduced fault rate, reduced manual maintenance cost.
