Discharging lifting cylinder lower limit detection device for lifting loading

Abstract

The invention discloses a discharging lifting cylinder lower limit detection device for lifting loading. The discharging lifting cylinder lower limit detection device for lifting loading comprises a mounting plate, a fixing plate is fixedly connected to one side of the top of the mounting plate, a processor is fixedly mounted at the end, close to the mounting plate, of the outer side of the fixingplate, and a first sliding groove is formed in the middle of the fixing plate; and a connecting plate of an L-shaped structure is fixedly connected to the position, located above the first sliding groove, of the outer portion of the fixing plate, and a second sliding groove is formed in the side, away from the fixing plate, of the connecting plate. According to the discharging lifting cylinder lower limit detection device for lifting loading, when a lifting cylinder descends to a supporting object below, it is timely detected that a detecting pulley moves, then a lower limit signal is emittedto warn surrounding workers, and a winding wheel is controlled to stop rotating; meanwhile, the device does not have a fixed lower limit and is not affected by the loading height of a vehicle, and asignal is sent to stop descending as long as the loading lifting cylinder is subjected to the supporting effect below, so that the situations that a copper rope is disengaged from a groove and a lifter is pulled to be damaged can be thoroughly prevented, and an automatic and dynamic lower limit detection signal is realized.

Description

technical field [0001] The invention belongs to the field of detection devices, in particular to a detection device for the lower limit of a blanking lifting cylinder for lifting and loading vehicles. Background technique [0002] In the existing life, in the lifting loading system that uses steel ropes for traction, due to the inconsistent height of the container of the loaded vehicle, or the change of the stacking height of the goods during the loading process, the lifting cylinder in the traditional loading system The lower limit position is fixed, and it often happens that the lifting cylinder is actually placed on the lower container or goods, but the fixed lower limit switch has not yet moved, causing the steel rope to detach from the reel, and the feeding lifting cylinder is stuck and damaged by the car. situation occurs. Invention content: [0003] The object of the present invention is to provide a lower limit detection device for the unloading cylinder for lifti...
