Description

Mounting and positioning tool for coke oven hearth plate sleeve

Technical Field

The utility model relates to the technical field of coke oven construction, in particular to a mounting and positioning tool for a coke oven hearth plate sleeve.

Background

A coke oven is a furnace generally built of refractory bricks and refractory blocks for carbonizing coal to produce coke. The kiln for making coke by using coal is a main thermal equipment for coking. The modern coke oven is a horizontal chamber type coke oven which mainly aims at producing metallurgical coke and can recover coking chemical products, and consists of an oven body and accessory equipment. The coke oven body consists of a furnace top, a combustion chamber, a carbonization chamber, a chute area, a regenerator and the like, and is connected with a chimney through a flue. The whole coke oven is laid on a concrete foundation. Modern coke ovens are generally the same in basic structure, but can be divided into many types due to different coal charging modes, heat supply modes and fuels used.

The coke oven hearth plate sleeves are mounted in a large quantity and have high precision requirements, and meanwhile, the mounting precision of the hearth plate sleeves is also the premise that the subsequent masonry mounting engineering is smoothly carried out. However, the prior art

Chinese patent with application number CN200910052154.4 for fixing device of pre-buried sleeve of coke oven basic roof, discloses a fixing device for pre-buried sleeve of coke oven basic roof, including longitudinal fixing frame, horizontal fixing frame, right angle plate and pre-buried sleeve, characterized by: the regulators at two sides of the machine coke of the basic roof of the coke oven are tied on the steel wires of the two regulators, the control wires of the transverse intervals of the embedded sleeves are thrown onto the longitudinal fixing frames at two sides of the machine coke through the central line of the coke oven, a measuring disc is placed on each row of the embedded sleeves, the embedded sleeves are transversely detected and aligned by the steel wires and longitudinally by the arrangement ruler, the top points of the measuring discs are aligned with the steel wires, and the embedded sleeves are abutted against the fixing stop blocks on the arrangement ruler. However, the device for fixing the embedded sleeve of the hearth plate of the coke oven is too complex and is not beneficial to construction on a construction site.

In conclusion, the prior art also lacks a positioning tool for installing a coke oven hearth plate sleeve, which is simple to manufacture, strong in operability, low in cost and convenient to carry.
