Description

Technical Field

[0001] The utility model relates to the technical field of double-column stackers, in particular to a double-column stacker. Background Art

[0002] After the goods are transported into the warehouse, they need to be stacked on the shelves. At this time, special stacking equipment in the warehouse is needed. Existing warehouse stacking equipment generally includes a walking mechanism and a mechanism arranged on the walking mechanism for stacking goods on the shelves. It is mainly composed of a walking mechanism, a lifting mechanism and a telescopic fork structure. The reliability and safety of the actions of these three mechanisms are crucial. With the development of warehouse stacking technology, the warehouse area is getting smaller and smaller, and the stacking equipment also needs to be changed accordingly to adapt to the stacking of goods in a small space. Since the shelves of modern warehouses are generally higher, a lifting mechanism is required. The lifting action is that the winch mechanism pulls the cargo platform up and down through a wire rope, and there is a risk of the cargo platform falling. The lifting mechanism on the existing stacker is not equipped with safety protection measures. Once a mechanical failure occurs, the consequences are disastrous. Publication (announcement) number: CN211004404U discloses a double-column stacker, comprising: a double-column bracket, a cargo platform, the cargo platform is equipped with a double-extend cargo fork for unloading materials; a lifting platform, two lifting platforms with the same structure are symmetrically connected at both ends of the cargo platform, and are respectively slidably connected to the first column or the second column on the same side; a lifting drive device for pulling the lifting platform, the driving device is fixedly installed on the double-column bracket; an overspeed protection device, the overspeed protection device is arranged on the lifting platform, and is slidably connected to the first column and the second column; by setting the overspeed protection device, when the cargo platform descends at an excessive speed and reaches the preset speed of the speed limiter, the speed limiter wire rope stops, and then the connecting rod stops, and the continued descent of the cargo platform will force the connecting rod to drive the safety clamp to move upward, and then the safety clamp is clamped to the column guide rail for fixation.
