Embedded scraper transporter head assembly having scraper chain automatic compensation function

Abstract

An embedded scraper transporter head assembly having the scraper chain automatic compensation function comprises a head shell, wherein an upper guide rail, a head wheel and a chain supporting knife are arranged in the head shell, a supporting wheel is installed in the head shell and fixed to a supporting wheel frame, the supporting wheel frame is located above the head wheel, and the supporting wheel is close to a wheel. According to the embedded scraper transporter head assembly having the scraper chain automatic compensation function, the supporting wheel is additionally arranged above the head wheel of an embedded scraper transporter, the supporting wheel is installed on the head of the embedded scraper transporter, and a hanging head is formed; when the transporter transports high-temperature materials, the difference between extension lengths of the shell and a chain can be effectively compensated for, and faults such as chain jumping, chain disengage, chain seizure and even chain breakage are avoided.

Description

technical field [0001] The invention relates to a buried scraper conveyor, in particular to a buried scraper conveyor head assembly with automatic compensation function of scraper chain. Background technique [0002] When the buried scraper conveyor transports high-temperature materials, the scraper chain is buried in the high-temperature materials, and its temperature is the same as that of the materials, but the temperature of the bottom plate and side plates of the buried scraper conveyor is only equivalent to the temperature of the materials. half. Although the scraper chain is stretched while the shell is also stretched, but because the scraper chain and the shell are different in material and temperature, the elongation length of the two is different, and there will be a large length during operation. Difference. Accompanied by the generation of this length difference, it will directly cause the problem of looseness and tightness between the head and tail wheels and ...

AI Technical Summary

Problems solved by technology

It can be seen that if the scraper chain is elongated without extra avoidance space, the following situations will occur: the chain will arch and grind to the upper cover when the chain is elongated, and chain skipping will occur; if the chain is loose and not tightened in time, it will appear The phenomenon of chain drop; the shortening of the chain will cause the chain to be too tight, so the friction between the chains and between the chain and the head and tail wheels will increase, which will increase the wear of related parts. The service life of wheels and scraper chains is severely shortened

[0004] It can be seen that the existing buried scraper conveyor does not solve the above-mentioned problems well. It only depends on the tension of the screw rod at the tail of the buried scraper conveyor to adjust the elongation of the chain, which requires manual observation and adjustment from time to time, which is inconvenient. also unreliable
