A frame structure of inner tension tail of plate chain bucket elevator

Abstract

The invention discloses an internal tensioning tail framework structure of a plate chain bucket lifter. The internal tensioning tail framework structure comprises a transverse rod, connecting rods, a tail shaft, tail wheels, counterweight wheels, a bearing base and a rolling bead bearing, wherein connecting rods are arranged at the two ends of the transverse rod; the transverse rod and the two connecting rods form a framework structure; the two ends of the tail shaft are connected with the connecting rods respectively; two tail wheels are symmetrically arranged on the tail shaft; two counterweight wheels are symmetrically arranged on the tail shaft; the counterweight wheels are positioned at one side of each tail wheel; the rolling ball bearings are arranged on the end part of the tail shaft; the rolling ball bearing is mounted in the bearing base; an end cover is mounted at one side of the bearing base, and a maze sealing ring is mounted at the other side of the bearing base; a framework oil seal is mounted in the bearing base; an oil cavity structure is arranged between the framework oil seam and the rolling ball bearing. The internal tensioning tail framework structure can be used for effectively preventing materials from entering an internal tensioning structure, and limiting the internal tensioning tail part through the framework, so that the tail shaft is integrally inclined and regulated, and the maze sealing ring and the bearing base are effectively prevented from rubbing with each other due to inclination of the tail shaft.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of chain bucket elevators, in particular to the technical field of a tension tail frame structure in a plate chain bucket elevator. [0003] 【Background technique】 [0004] The plate chain bucket elevator is the most widely used vertical lifting equipment. This machine is suitable for vertical transportation of medium, large and abrasive materials (such as limestone, cement clinker, gypsum, lump coal). Below 250 ℃, the plate chain bucket elevator is composed of running parts, driving device, upper device, middle casing and lower device, and a tensioning device is installed in the lower device. Most of the tensioning devices in the prior art are exposed to the external environment, and materials are easy to enter the tensioning device, causing equipment wear and seriously affecting the service life of the equipment. In addition, the existing tensioning device lacks a frame structure to limit the incli...

Problems solved by technology

Most of the tensioning devices in the prior art are exposed to the external environment, and materials are easy to enter the tensioning device, causing equipment wear and seriously affecting the service life of the equipment. In addition, the existing tensioning device lacks a frame structure to limit the inclination of the tail shaft , the tail shaft in the equipment is easy to incline in one direction and cause the labyrinth to rub against each other, which reduces the working efficiency and service life of the equipment
