Packed material large-slope lifting device

Abstract

The invention relates to a high gradient lifting device, specifically speaking, a high gradient lifting device for bagged material, which includes a left frame and a right frame; each of the left frame and the right frame is respectively provided with a driving sprocket, a supporting sprocket and a tensioning sprocket; two sets of short-pitch transfer chains are respectively engaged and connected with the driving sprocket, the supporting sprocket and the tensioning sprocket arranged on the left frame and the right frame to make cycle motion. The invention is characterized in that a lower bolster and an upper pressure board are respectively articulated with the transfer chain so as to form a lower bolster group and an upper pressure plate group, an S-shaped bagged material lifting transfer passage is formed between the lower bolster group and the upper pressure plate group of the two transfer chains. The invention has the advantages that: (1) the device reduces the labor input, decreases the handling cost, and improves the labor intensity of the worker and the work efficiency; (2) the bag is difficult to be clamped or damaged; (3) the lifting transportation of bagged material can be realized within the angle range of 30-90 DEG and the transfer speed and the reliability of the bagged material can be effectively improved.

Description

technical field [0001] The invention relates to a large-slope lifting device, in particular to a large-slope lifting device for bagged materials. Background technique [0002] At present, the mechanized loading and unloading of bagged materials at home and abroad mainly adopts pallet forklifts and hanging bag lifting methods. Both of these two loading methods are discontinuous operations, and their main disadvantages are that pallets or hanging bags must be pre-laid before material stacking, and the pallets or hanging bags are transported with vehicles and ships, which makes recycling difficult, large consumption, and high loading and unloading costs. [0003] There is another way that bagged materials are transported and loaded by belts, which is a continuous operation and can share equipment with the stacking system, with low investment and operating costs. However, the belt conveyor loading system is rarely used at home and abroad. The main reason is that key technologie...

Problems solved by technology

However, the belt conveyor loading system is rarely used at home and abroad. The main reason is that key technologies such as large-slope lifting of bagged materials in a confined space have not been broken through.

The maximum climbing angle of bagged materials transported by belts is generally less than 30°. If two belts are used to clamp and lift bagged materials, the material will flow toward the end due to the extrusion of the belts, and the end of the material bag may be burst; Lifting by steps with tapes with a small slope not only occupies the effective storage capacity, but also easily jams and breaks bags at the tape interface, resulting in low operational reliability
