Description

Anti-falling coil mechanism of coil lifting device Technical Field The utility model relates to the technical field of steel coil lifting anti-falling, in particular to a steel coil lifting device anti-falling mechanism. Background The steel coil lifting device is special equipment for vertically or horizontally conveying steel coils and is widely applied to the fields of steel works, logistics warehouse, automobile manufacturing and the like. The main functions of the steel coil lifting machine comprise lifting, overturning, stacking, loading and unloading and the like, and the safety, the high efficiency and the stability are ensured, so that the deformation or the damage of the steel coil is avoided. The steel coil lifting device in the steel coil conveying area lifts steel coils, and the lifting hydraulic cylinder is extremely large in vertical downward pressure when working, the hydraulic pipeline bursts due to the probability, the hydraulic rod of the hydraulic cylinder loses supporting pressure, the hydraulic rod drops instantly, the steel coils instantly fall, damage to the steel coils, injury to surrounding operators, crashing of nearby related equipment and the like occur, the danger is high, the potential safety hazard is huge, and the steel coil lifting device is required to prevent the falling of the steel coil lifting device to ensure that the steel coil position is locked and not to fall under the condition that the hydraulic pipeline bursts. Disclosure of utility model In order to overcome the defects of the prior art, the utility model provides the anti-falling coil mechanism of the steel coil lifting device, which is controlled by interlocking the pressure sensor and the anti-explosion mechanism, when the oil pressure suddenly drops in an oil inlet tube explosion tube and is detected by the pressure sensor, the interlocking control anti-explosion mechanism reversely cuts off the rodless cavity of the hydraulic cylinder to leak hydraulic oil to the oil inlet tube, the hydraulic oil is locked in the rodless cavity, the hydraulic rod is reversely locked, the lifting rack, the steel coil seat and the steel coil are locked at the current position together, the falling coil accident is avoided, the steel coil protection capability is improved, the safety of surrounding operators is improved, the risk of smashing surrounding equipment is avoided, and the potential safety hazard of steel coil lifting is avoided. In order to achieve the above purpose, the utility model is realized by adopting the following technical scheme: The utility model provides a coil of strip hoisting device anti-falling mechanism, includes coil of strip seat, promotes rack, promotes pneumatic cylinder, explosion-proof mechanism, advances oil pipe and pressure sensor, promote rack top set up the coil of strip seat, promote rack bottom and set up the promotion pneumatic cylinder, the rodless chamber of promotion pneumatic cylinder set up into oil pipe, advance oil pipe bottom and rodless chamber hookup location and set up explosion-proof mechanism, advance oil pipe on set up pressure sensor, explosion-proof mechanism and pressure sensor between interlocking control. Further, the explosion-proof mechanism comprises an upper reducing pipe, a lower reducing pipe, an explosion-proof valve and a pipe joint, wherein the oil inlet pipe is connected with the upper reducing pipe, the upper reducing pipe is connected with the explosion-proof valve, the explosion-proof valve is connected with the lower reducing pipe, and the lower reducing pipe is connected with the bottom of a rodless cavity of the lifting hydraulic cylinder through the pipe joint.
