Feeding and conveying device used for hoisting chain

Abstract

The invention discloses a feeding and conveying device used for a hoisting chain. The feeding and conveying device comprises a feeding hopper, a first discharging port is formed in the lower end of the feeding hopper, a discharging straight pipe is fixed to the first discharging port, a conical pipe is fixed to the lower end of the discharging straight pipe, four first limiting grooves are formedin the inner wall of the conical pipe, and the included angle between every two adjacent first limiting grooves is 90 degrees. A conveying box is arranged below the conical pipe, a feeding port is formed in the upper end of the conveying box, a second discharging port is formed in the lower end of the conveying box, four limiting plates are arranged between the conical pipe and the conveying box,the included angle formed between every two adjacent limiting plates is 90 degrees, a gap is reserved between every two adjacent limiting plates, second limiting grooves are formed in the inner wallsof the limiting plates correspondingly, more than two straight channels are arranged in the conveying box in parallel, and every two adjacent straight channels are in communication through an arc-shaped channel. The feeding and conveying device used for the hoisting chain can prevent the chain from being twisted at will.

Description

technical field [0001] The invention relates to a feeding device, in particular to a feeding conveying device for a lifting chain. Background technique [0002] The lifting chain is an essential and important pick-up device for the crane. The length of the chain can be adjusted according to the lifting height of the lifting object, which plays an important role in improving the operating efficiency of the crane and expanding the operating range of the crane. The lifting chain is interlocked and connected by several chain links. The lifting chain needs to be cut or processed with high precision during the production process. However, because the chain links of the lifting chain cannot be completely fixed, the lifting chain cannot Problems such as twisting and offset will occur, resulting in different angles formed between every two adjacent links, which will affect the high-precision processing of the chain. Contents of the invention [0003] The object of the present inve...
