Conveying chain

Abstract

The invention relates to the technical field of mechanical transmission, and specifically relates to a conveying chain. The conveying chain comprises inner chain plates, outer chain plates, a pin shaft and a sleeve, wherein the pin shaft sequentially penetrates through the outer chain plate at a rear side, the inner chain plate at the rear side, the sleeve, the inner chain plate at a front side and the outer chain plate at the front side from the rear to the front; a high-hardness guide plate is welded and fixed to a side end surface away from the corresponding inner chain plate, of each outerchain plate; and welding layers are welded to the upper edges of each inner chain plate and the corresponding outer chain plate, heat dissipation windows are formed in each inner chain plate and thecorresponding outer chain plate, a step surface is machined at a rear end of the pin shaft, a retainer ring groove is machined in a front end of the pin shaft, and a locking retainer ring is installedin the retainer ring groove in a clamping manner. According to the conveying chain, the wear and the deformation of the chain plates is greatly reduced, and meanwhile, the service lives of the guideplate and the chain are effectively prolonged; and the conveying chain is worthy of being popularized and used.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission, in particular to a conveying chain. Background technique [0002] Chains are generally metal links or rings, which are mostly used for mechanical transmission and traction. During the use of the chain of the cooling bed machine, due to the high temperature of the conveyed section steel, the heat is directly transmitted to the chain. The temperature of the chain is from 600°C to normal temperature when the steel section enters the cooling bed and then leaves the cooling bed. Due to thermal expansion and contraction, the cooling of the parison drives the chain to move sideways during operation, and the channel is laterally squeezed, causing wear. Due to the hardness problem of the guide plate and the friction of the guide rail, the guide plate is excessively worn and then the chain plate is worn and the chain fails. Therefore, the problems that need to be solved urgently for the c...

During the use of the chain of the cooling bed machine, due to the high temperature of the conveyed section steel, the heat is directly transmitted to the chain. The chain enters the cooling bed from the section steel to the cooling bed, and the temperature ranges from 600°C to normal temperature. Due to thermal expansion and contraction, the cooling of the parison drives the chain to move sideways during operation, and the channel is laterally squeezed, resulting in wear

Due to the hardness problem of the guide plate and the friction with the guide rail, the guide plate is excessively worn and the chain plate is worn out, causing the chain to fail
