Abstract
The invention discloses a connecting structure for a crank arm of a hydraulic clay gun and a hydraulic cylinder. The connecting structure comprises the hydraulic cylinder, an oil cylinder cross beam and the crank arm, wherein the oil cylinder cross beam is fixed to the hydraulic cylinder; two lateral plates of the crank arm are correspondingly provided with mounting holes; both ends of the oil cylinder cross beam pass through the mounting holes; the outer sides of the mounting holes are fixedly provided with glands through fastening components; the glands are provided with oil injection joints; the oil injection joints are communicated with oil ducts formed in the glands; and self-lubricating copper bushes are arranged between the glands and the oil cylinder cross beam. According to the connecting structure for the crank arm of the hydraulic clay gun and the hydraulic cylinder, the self-lubricating copper bushes are used for replacing the ordinary copper bushes, and the abrasion is well prevented by means of the self lubricating effect of the self-lubricating copper bushes even if the phenomenon that lubricating oil is interrupted exists. The connecting structure is simple in structure, easy to realize, long in service life and safe and reliable in operation.
Description
Technical field
The present invention relates to a kind of Hydraulic clay gun, relate in particular to cranking arm and the hydro-cylinder syndeton of a kind of Hydraulic clay gun.
Background technology
Hydraulic clay gun has another name called the blast furnace ironmaking clay gun, iron-smelting blast furnace clay gun, blast furnace Hydraulic clay gun, blast furnace gun; Belong to the indispensable casthouse equipment of smelting industry.The effect of Hydraulic clay gun is can be rapidly accurately to stop up the iron notch of putting behind the iron; Make blast furnace get into next round-robin operation fast; Than mechanical clay gun; That Hydraulic clay gun has is in light weight, simple in structure, operate steadily, stable and reliable for performance, efficient is high, easy to operate, lower-price characteristic, is the comparatively ideal casthouse equipment of present large, medium and small ironmaking producer.
The hydro-cylinder of Hydraulic clay gun is connected with two side plates of cranking arm through the oil cylinder crossbeam, cranks arm and under works better, will rotate continuously, therefore in order to prevent the wearing and tearing between oil cylinder crossbeam and the side plate; Usually between is provided with copper sheathing, for fear of the copper sheathing rapid wear oiling joint is set also simultaneously, and is regularly oily through the oiling joint; But when concrete operation, have carelessness unavoidably, it is lubricated to fail timely intermittent oiling; Cause the copper sheathing wear damage, cause the equipment can't works better.
Summary of the invention
The object of the present invention is to provide cranking arm and the hydro-cylinder syndeton of a kind of Hydraulic clay gun; It has simple in structure, be easy to realize, long service life and the high characteristics of safe reliability, effectively solved the problem of cranking arm and existing with the hydro-cylinder syndeton of Hydraulic clay gun in the prior art.
The objective of the invention is to realize through following technical scheme:
Cranking arm and the hydro-cylinder syndeton of a kind of Hydraulic clay gun; It comprises hydro-cylinder, oil cylinder crossbeam and cranks arm that said oil cylinder crossbeam is fixed on the hydro-cylinder, corresponding mounting holes on said two side plates of cranking arm; The two ends of said oil cylinder crossbeam penetrate in the open hole; The outside of said open hole is fixed with gland through secure component, and wherein, said gland is provided with the oiling joint; The said oiling joint oil duct interior with being opened in gland is connected, and between said gland and the oil cylinder crossbeam self-lubricating copper sheathing is set.
Especially, be provided with backing plate between the said gland and the side plate of cranking arm.
Especially, said secure component is a standing bolt, and the matching and fixing bolt is corresponding to perforate on gland, backing plate and the side plate of cranking arm.
Beneficial effect of the present invention does; Crank arm and the hydro-cylinder syndeton of said Hydraulic clay gun compared with prior art adopt the self-lubricating copper sheathing to replace common copper sheathing; The self-lubricating copper sheathing is the conjunction of copper base material matter and graphite material, and graphite material is good lubricant, even lubricating oil phenomenon out of stock is so arranged; Also can well avoid wearing and tearing, not only simple in structure, be easy to realize; And long service life, safe and reliable to operation.
