Abstract
The utility model relates to a hydraulic low-height clay gun which is composed of a knockout mechanism, a pressure gun mechanism and a swing mechanism. An oil cylinder of the pressure gun mechanism (5) directly pushes fixed wheel shafts (18) of traveling wheels (3) on both sides of the gun body (1) to make the gun body slope towards a guiding groove of a door-shaped frame. The tilting angle of the gun body can be regulated by altering the thickness of a pad (16) between a wheel shaft (18) and a wheel seat (12).
Description
The special-purpose metallurgical equipment of plugging behind a kind of blast furnace casting.
Hydraulic clay gun is compared with old-fashioned electric clay gun has advantages such as the mud power of beating is big, device height is little, and abrasion piece consumption is few.Existing hydraulic pressure low clay gun mainly contains three kinds:
1.IHI type.See U.S. Pat 403355,1977(Japanese Patent JP51-95238,1976).It is big, highly little that this kind clay gun is beaten mud power, had special locking latches to make the clay gun action fast, and it is reasonable that big gun is chewed movement locus, but remotely operated, but what press that big gun mechanism uses is the slideway that exposes, it is easy to wear because of laying dust, and moving resistance is increased and does not press tightly big gun and chew.In addition, the barrel traversing mechanism is to adopt large-size rolling bearing, the rotary joint complex structure of barrel center of turning circle, so make the manufacturing cost height, physical dimension is also big.
2.MHG type.This is the improvement of IHI type, and it presses big gun mechanism to adopt toggle not have exposed slideway, and the shortcoming of traversing mechanism still exists.
3. inclination basic type.See English Patent UK213694OA, 1984.This kind clay gun has only clay extruded mechanism and traversing mechanism, finishes barrel rotation, barrel by two oil cylinders and a cover linkage and tilts, compresses big gun and chew and beat actions such as mud.Simple and light, but the axis of barrel traversing mechanism tilts, and the basis is installed also tilts, so setting accuracy be cannot say for sure to demonstrate,prove.In addition, the off-position of clay gun is higher, the inconvenience of dress mud.
Therefore, at the many dirt of operating environment, the narrow and small condition in place before China's State of Blast Furnace, it is task of the present invention that the advantage of the existing hydraulic pressure low clay gun of absorption designs a kind of novel hydraulic low clay gun.
Hydraulic pressure low clay gun overall structure of the present invention as shown in Figure 1.Form by three parts such as clay extruded mechanism, pressure big gun mechanism and traversing mechanisms.
Clay extruded mechanism is contained in the inside of barrel (1), and the barrel forebody is the mud cylinder, and latter half of being equipped with presses mud oil cylinder (5) to adopt the oil cylinder piston bar to fix, and beats mud thereby the cylinder block motion promotes the method for mud cylinder piston motion.Cooling water tank (2) is equipped with in the bottom of barrel (1), and mud cylinder and pressure mud oil cylinder (5) are played the thermal insulation protection effect.
Press big gun mechanism to adopt the structure of barrel (1) along guide path (11) motion.Four travelling wheels (3) are equipped with at the rear portion of barrel (1), can roll in the guide path (11) of door-shaped frame (4).The shape of guide path (11) can guarantee to be the level of state when barrel (1) enters iron notch mud cover (10) with the angle straight line that requires and returns to the back limit position.
Barrel (1) is realized by the fixedly wheel shaft (18) of pressing gun oil cylinder (5) directly to promote wheel (3) along the motion of guide path (11), barrel (1) good rigidly, and travelling wheel (3) spacing is little, so that the both sides travelling wheel can keep is synchronous.Travelling wheel (3) is contained in (not shown) on the rolling bearing on the wheel shaft (18), so the traveling resistance is little, and reliable operation, the life-span is long.
Door-shaped frame (4) is rigidly fixed to the end of pivoted arm (6), barrel (1) leans on ram cylinder (8) and linkage to drive pivoted arm (6) and rotates, pivoted arm (6) rotates around stationary shaft (17), stationary shaft (17) up and down clamping in frame-type support (7), frame-type support (7) has higher stiffness, so stationary shaft (17) is highly less, and need not turn round parts such as stand, big bearing, bull gear, scantlings of the structure is less.
The ram cylinder of traversing mechanism (8) can bear the counter-force when pressing big gun, and big gun was chewed and is adjacent to iron notch mud cover (10) all the time when the locking loop of dependence hydraulic efficiency system can guarantee to beat mud.Grasp device (9) also is equipped with in the bottom of pivoted arm (6), and it and hydraulic locking apparatus have locking effect simultaneously, to guarantee the reliability of clay gun work.
Travelling wheel (3) on barrel (1) the installation site and mounting means as shown in Figure 2.Be welded with wheel mount (12) on the barrel (1), axletree (15) is fixed on the wheel mount (12) with bolt (13) and wedge (14).Be equipped with between axletree (15) and the wheel mount (12) and regulate pad (16), the thickness that changes pad (16) has just changed travelling wheel (3) in the position of barrel (1), thereby adjusts the angle of inclination of barrel (1) when pressing big gun.
The advantage of this kind hydraulic pressure low clay gun is:
1. compact construction.With other clay gun ratios of identical performance perameter, this kind clay gun height is little, and overall size is little.
2. because of rotating mechanism adopts linkage, press big gun mechanism travelling wheel structure, not only designs simplification, reliable operation, and can adapt to the environment of the many dirt in stokehold, the splash of not being afraid of molten iron and slag liquid.
3. big gun is chewed straight line and is entered iron notch, helps the mud raising in cover life-span.
4. the support of this kind clay gun and basis are all horizontal surface, and it is all more convenient to install and adorn the mud operation.
Accompanying drawing 1. hydraulic pressure low clay guns.
The installation of accompanying drawing 2. travelling wheels.
Claims (2)
1, a kind of hydraulic pressure low clay gun, form by barrel, pressure big gun mechanism, traversing mechanism and grasp device, the invention is characterized in: four travelling wheels (3) are equipped with in the both sides of this clay gun barrel (1), press big gun mechanism that a pressure gun oil cylinder (5) and a guide path (11) that is located on the door-shaped frame (4) that directly promotes the fixedly wheel shaft (18) of travelling wheel (3) is arranged, a setting device that changes pad (16) thickness.
2, clay gun as claimed in claim 1, its feature is that also the angle of inclination setting device of used barrel (1) is with bolt (13) and wedge (14) wheel shaft (18) to be fixed on the wheel mount (12), and the pitch angle of barrel (1) when pressing big gun with the method adjustment that change is located at pad (16) thickness between wheel shaft (18) and wheel mount (12).
