Ferroalloy rotating chute

Abstract: The utility model discloses a ferroalloy rotating chute, which is designed for solving the problems that a conventional device is easy to get stuck and the like. The ferroalloy rotating chute at least comprises a base, a slewing bearing of which an inner ring is fixedly connected with the base, a hopper which is connected with an outer ring of the slewing bearing, a gear which is meshed with the outer ring of the slewing bearing, a gear motor which is used for providing power for the gear, and an elephant trunk which is connected to the lower end of the hopper, wherein induction blocks are arranged on the hopper; a proximity switch is arranged at a position corresponding to the base; draw bars are crosswise staggered in the hopper; a lubricating oil way is arranged on the slewing bearing; a dust cover is arranged above the hopper; and a double-layer nitrogen sealed ring is arranged on the dust cover. The ferroalloy rotating chute is reasonable and compact in structure, is not easy to get stuck, high in working efficiency, long in service life and convenient to maintain, and can be used in the process of charging furnace rear ferroalloy into converters in various steelshops.

Rotatory material arm device of scraping suitable for center batcher

Abstract: The utility model relates to a rotatory material arm device of scraping suitable for center batcher, including feed bin body, support arm, water conservancy diversion awl, rotatory material arm, slewing bearing, blanking table, play feed bin, the proof warp parts scraped, the water conservancy diversion is bored through the fixed setting of support arm cooperation originally internally at the feed bin, the upper feeding port who goes out the feed bin coordinates is disposed under the water conservancy diversion awl, slewing bearing's take tooth outer lane and the rotatory material arm of scraping coordinate fixed connection, slewing bearing's inner circle and play feed bin cooperation fixed connection, fastening bolt and connecting piece cooperation fixed connection are passed through to the rotatory material arm one end of scraping, and the connecting piece is connected with slewing bearing's the tooth outer lane cooperation of taking, rotatory other end level of scraping the material arm is outwards extended, and the top of other end extension back is tangent with the inner wall of feed bin body, the proof warp part encircles and sets up on the inner wall of feed bin body Material choking can be avoided to this device, prevents to scrape the material arm and upwarps, improves production efficiency

Space overlying double-rotation single-row ball type slewing bearing

Abstract: The utility model disclose a space overlying double-rotation single-row ball type slewing bearing which comprises an inner ring, an outer upper ring, an outer lower ring, rollers, oil nozzles and sealing strips The space overlying double-rotation single-row ball type slewing bearing is characterized in that two outer rings are arranged on the outer portion of the inner ring, and the two outer rings are respectively arranged on the upper portion and the lower portion of the outer side of the inner ring, and sealed by the sealing strips so as to enable two rolling channels to be corresponding sealed spaces The number and positions of the oil nozzles are decided according to working condition The space overlying double-rotation single-row ball type slewing bearing is compact and reasonable in structure, and safe and reliable in usage, effectively saves space, guarantees loading, not only meets requirement of mechanical enlargement, but also further expands application fields of the slewing bearing

Transport device with transverse inclination device

Abstract: A transport device with transverse inclination device for transporting heavy loads is described, consisting of a loading bridge or tank-truck bridge which rests with the front and rear region on the faces of a front and rear chassis by means of in each case one ball bearing slewing ring, the chassis having a plurality of wheel axles and hydraulic cylinders being provided which as a result of pressure being fed in the event of an inclination of the road incline the loading bridge in the opposite direction so that it always remains in the horizontal position. This is based on the object, in particular in the areas of bends when the chassis are inclined and offset at an angle to the loading bridge, of continuously keeping the loading bridge in a horizontal position in the transverse direction in a constructionally simple manner. For this purpose, there is provision for in each case one transverse oscillating bearing to be provided on the ball bearing slewing ring of the front and rear chassis and for the loading bridge to be arranged in the front and rear region on the transverse oscillating bearing, and for hydraulic cylinders to be arranged at the rear chassis to the left and right of the longitudinal axis of the transverse oscillating bearing, which hydraulic cylinders are supported on the one hand on the ball bearing slewing ring and on the other hand on the loading bridge.

Novel aerial ladder fire -fighting robot

Abstract: The utility model discloses a novel aerial ladder fire -fighting robot belongs to the robotechnology field. Its aerial ladder elevating system includes lifing arm, lift cylinder, bracket, swing hydro-cylinder, jacking cylinder and high pressure water cannon, rotation mechanism includes slewing bearing, and running gear includes chassis, diesel engine, sprocket and track, and slewing bearing fixeson the chassis, and diesel engine, control box are all fixed on the chassis, and the track takes turns to at the chain around establishing, wherein to pass through adjustment mechanism and slewing bearing fixed for the lifing arm, and lift cylinder fixes on the lifing arm, and the bracket is articulated with the head of lifing arm, and the cylinder body of swing hydro -cylinder is fixed on the lifing arm, and the piston rod is fixed on the bracket, and high pressure water cannon fixes on the bracket with rotating, and fixes with jacking cylinder. Can the head of robot be 0 180 the within range is adjusted from top to bottom for the fire prevention wide range that disappears of this robot can actively be rescued effectively, ensures the reliability of rescue, avoids the casualties.
