Abstract
The utility model relates to a protector for longevity of a hydraulic cylinder of a ladle slide gate, which is characterized in that a water-cooling structure exists; the protector comprises a spring-shaped water cooling tube (1) and a protective shell (2), wherein the spring-shaped water cooling tube (1) is prepared through carrying out hot bending on a stainless steel thin tube according to the lengths and widths of a barrel (3) of the hydraulic cylinder and an oil return pipe (8), the protective shell (2) is arranged at the outside of the water cooling tube (1), two ports of the stainless steel thin tube are respectively connected with a water inlet joint (4) and a water outlet joint (5) on the same side face of the protective shell (2) of the water cooling tube in a butt joint mode, the two end parts of the barrel (3) of the hydraulic cylinder are respectively provided with two pin holes (6), fixed pins (7) are arranged on the water cooling tube protective shell (2) corresponding to the pin holes, and a water-cooling structure is fixed at the length-direction peripheries of the barrel (3) of the hydraulic cylinder and the oil return pipe (8) through the pin holes (6) by using the fixed pins (7). A lift handle (9) is welded and fixed on the protective shell (2).The protector disclosed by the utility model is simple in structure, convenient for replacement and reliable in operation, and remarkably reduces the environmental temperature of the hydraulic cylinder.
Description
Technical field
The utility model belongs to the steelmaking equipment technical field, relates in particular to a kind of steel ladle sliding water gap hydraulic cylinder longevityization protective device.
Background technology
In the conticaster normal productive process, because the steel ladle sliding water gap hydraulic cylinder is in the middle of the hot environment all the time, under situation without any protection, the slide gate nozzle hydraulic cylinder self is subjected to very strong heat radiation, cause the seal material of hydraulic cylinder to damage because of high-temperature baking is rotten, lose sealing function, hydraulic cylinder changing is frequent, both can't ensure that production carried out smoothly, also increase production cost.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of steel ladle sliding water gap hydraulic cylinder longevityization protective device, has guaranteed the normal operation of conticaster.For achieving the above object, the technical scheme that the utility model adopted is as follows: a kind of steel ladle sliding water gap hydraulic cylinder longevityization protective device, it is characterized in that: be provided with a water-cooling structure, comprise a spring-like water cold sleeve and protection housing, the spring-like water cold sleeve is made according to the length and the width hot bending of hydraulic cylinder cylindrical shell and oil return pipe by a stainless steel tubule, at the outside protection housing that exists of water cold sleeve, stainless steel tubule two-port is docked with water cold sleeve protection housing same side water inlet joint and delivery port joint respectively, respectively be provided with two pin-and-holes at hydraulic cylinder cylindrical shell both ends, at water cold sleeve protect housing on corresponding with pin-and-hole is provided with steady pin, and water-cooling structure utilizes steady pin to be fixed in hydraulic cylinder cylindrical shell and oil return pipe length direction periphery by pin-and-hole; A carrying handle is fixed in welding on the protection housing.
The utility model is simple in structure, it is convenient to change, reliable, significantly reduced the hydraulic cylinder environment temperature, solve the hydraulic cylinder sealing element material preferably and damaged frequent problem because of high-temperature baking is rotten, guarantee the stable operation of hydraulic cylinder, effectively improved the operating rate of hydraulic cylinder service life and conticaster, reduced production cost.
