Description

Continuous unloading stacker for flexible freight bags Technical Field The invention belongs to the technical field of storage and transportation equipment, and relates to a continuous unloading stacker for flexible freight bags. Background The continuous unloading and stacking machine for the flexible freight bags is core equipment in the field of heavy bulk cargo logistics, is responsible for walking on warehouse rails, and realizes vertical transportation and accurate stacking of the flexible freight bags through a lifting mechanism. The lifting mechanism of the stacker commonly adopts a plurality of steel wire ropes to synchronously lift the cargo carrying platform. However, breakage of the wire rope due to fatigue and abrasion is a significant safety hazard for the long-term existence of such equipment. Once the single rope is broken, the cargo carrying platform can incline and unstably instantly, and the falling of the cargo, the damage of equipment and even personal accidents are easily caused. At present, an emergency braking device is commonly added on a stacker in the industry, but friction braking or mechanical blocking is usually carried out under the state that a platform is inclined. Because of poor contact and uneven stress in an inclined state, the 'passive response' safety design has inherent defects of braking slip and insufficient locking force, and cannot fundamentally guarantee the operation safety of the stacker. Therefore, the continuous unloading stacker for flexible freight bags is developed, so that when the continuous unloading stacker detects rope breakage faults, the attitude of a platform can be actively corrected, and then reliable locking is implemented, and the continuous unloading stacker has important significance for improving the safety level of the whole industry The invention relates to the technical field of storage and transportation equipment, in particular to a stacker, which comprises a walking chassis, wherein a plurality of moving wheels are arranged at two ends of the walking chassis, a vertical frame is fixedly connected to the top end of the walking chassis, sliding rails are respectively and fixedly connected to two sides of the outer surface of the vertical frame, a braking device is arranged at the bottom end of a base, the braking device comprises a plurality of speed sensors, two supporting plates and two sliding rods, the two ends of the two sliding rods slide on the inner walls of first sliding grooves at one side of the two supporting plates respectively. Above-mentioned prior art is when the rope breakage leads to the tray slope back, tries to directly press from both sides tight guide rail or carry out friction braking under the inclined condition, because of the contact surface is improper, the atress is uneven, very easily leads to skidding, jamming or locking force not enough, exists the secondary risk of inefficacy. Therefore, the invention provides a flexible freight bag continuous unloading stacker, which is designed to be actively leveled firstly and reliably locked later by a safety control assembly, so that the stacker fundamentally overcomes the braking failure caused by the inclination of a cargo platform when the traditional stacker breaks ropes, obviously improves the safety and reliability of equipment under extreme working conditions, and is suitable for heavy material handling scenes with strict safety requirements. Disclosure of Invention The invention aims to solve the technical problems that after a pallet tilts due to rope breakage, an existing stacker tries to directly clamp a guide rail or perform friction braking in a tilting state, and the existing stacker is very easy to cause slipping and clamping stagnation due to uneven contact surfaces and uneven stress, so that the locking force is insufficient, and the risk of secondary failure exists.
