Trolley linkage structure of trolley-type thermal treatment furnace

Abstract

The invention provides a trolley linkage structure of a trolley-type thermal treatment furnace. Two adjacent trolley frames are completely independent; the butt joint of the table tops of two adjacent trolleys is covered by a frame; a masonry on the inner side of the frame is a special-shaped brick; the height of the special-shaped brick is higher than that of the upper edge of the frame; a sealing structure is arranged between the two adjacent trolley frames; clay bricks are arranged between the special-shaped bricks of the two adjacent trolleys and above the sealing structure; longitudinal beams of the two adjacent trolleys are detachably and fixedly connected. The trolley linkage structure of the trolley-type thermal treatment furnace is simple, reasonable and compact, can easily realize separation of the two adjacent trolleys, is convenient in trolley wheel bearing and gear replacement, and can be used for greatly lowering the maintenance cost of trolley bearings and gears.

Description

technical field [0001] The invention relates to industrial furnace technology, in particular to a trolley connection structure for a trolley-type heat treatment furnace. Background technique [0002] At present, the connection between each section of the trolley in the trolley-type heat treatment furnace is a structural form of connecting the longitudinal beams of adjacent trolleys or connecting the hinge pins through steel plate welding. Regardless of the type of connection, the masonry on the upper part of the trolley is an integral structure, which is simple in manufacturing process and convenient in construction. However, in this connection method, the frame of the trolley and the masonry of the trolley adopt an integral structure, which makes it difficult to repair the wheel bearing or the driving gear, and the maintenance cost increases greatly; The masonry of the trolley at the joint of the longitudinal beam, and then cut the steel plate and the connecting plate of t...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the trolleys of the existing trolley-type heat treatment furnaces are connected as an integral structure, which makes it difficult to separate two adjacent trolleys, which in turn makes it difficult to maintain wheel bearings or driving gears and high maintenance costs. Trolley-type heat treatment furnace trolley connection structure, the connection structure is simple, can easily realize the separation of two adjacent trolleys, facilitate the replacement of trolley wheel bearings and gears, and greatly reduce the maintenance cost of trolley bearings and gears
