Gate trolley

Abstract

An excellent weight-balanced lap furnace cap loading-unloading machine and its gated trolley of furnace frame sweeper are disclosed. It is overlapped on mover (51) freely by furnace chamber line of coke furnace and operated movingly by furnace chamber, main frame (62) is supported by body laid on rail of mover (51), the main frame consists of at least two connected longitudinal pillars (62A) and (62B), which support furnace cap loading-unloading machine (16) and furnace frame sweeper (17) moving freely, guide grille (56) is arranged between furnace cap loading-unloading machine (16) and furnace frame sweeper (17).

Description

Technical field [0001] The present invention relates to a portal trolley, which is arranged on a moving machine such as a coke pushing machine, a coke guide car, and a coke conveying car (CTC) that is freely movably arranged along the furnace chamber row of a coke oven. Background technique [0002] Moving machines such as coke ejectors and coke guide cars, which are movably arranged along the row of coke oven chambers, have conventionally equipped with independently mounted furnace cover loading and unloading machines ( Lid lifter) and the movable trolley of the furnace frame sweeper (valve seat surface cleaning machine) for cleaning the valve seat surface of the furnace frame or the inner surface of the kiln mouth, etc., and each movable trolley is opposed to the furnace The cover moves forward and backward independently. In addition, there are cases where the furnace frame sweeper is integrated on the side of the furnace cover loader, and a single support frame arranged vertic...

AI Technical Summary

Problems solved by technology

[0003] As mentioned above, when the furnace roof loading and unloading machine or the furnace frame sweeper are mounted on independent mobile carts, multiple rails are required, and each mobile cart needs to be equipped with a driving mechanism for a driving source, so the following appears: The problem is that not only the mechanism becomes complicated and the price of the mobile machine becomes higher, but also the operation control is complicated and the maintenance and inspection become cumbersome

[0004] In addition, when installing the furnace frame sweeper on the side of the furnace roof loading and unloading machine accompanying the rotation, although a single moving trolley is sufficient, since a large eccentric load acts on the supporting frame, the following problems arise. Poor weight balance of the trolley, difficulty in centering when loading and unloading the furnace cover, partial wear of the wheels of the trolley or distortion on the trolley

In addition, when the furnace frame sweeper is installed on the opposite side of the furnace cover loading and unloading machine, in order to avoid interference with the driving device of the ejection ram (ram) of the coke ejector, the structure of the mobile trolley is complicated, and the design is complicated. Significantly reduced freedom of layout and greater eccentric loading effects relative to the support frame
