Protection device for thickener slewing bearing and drive motor

Abstract: The utility model relates to the technical field of thickeners in the mineral processing technology, and especially a protection device for a thickener slewing bearing and a drive motor. The device comprises an original drive circuit of a thickener, a slide wire, a current collector, a three-phase current transformer, a drive motor protector, a trip and sound-light alarm device, and an RS485/RS232 converter, wherein the three-phase current transformer, the drive motor protector, the trip and sound-light alarm device and the RS485/RS232 converter are disposed among the drive circuit, the slide wire and the current collector, and are connected sequentially. A first circuit breaker of a shunt release is disposed among the slide wire, the current collector and the motor, or a second circuit breaker QF2 is disposed between a driver circuit of the drive motor and a three-phase power supply. The RS485/RS232 converter is connected with an upper computer and a display. The device protects the drive motor, and also protects the thickener slewing bearing. The device can protect the slide wire of the drive motor against poor contact or phase failure, so the device can achieve the comprehensive protection. The device is high in protection precision, is accurate in operation, is high in resistance to interference, and can effectively protect the thickener slewing bearing.

Rotary type belt conveyor with controllable angle

Abstract: The invention discloses a rotary type belt conveyor with a controllable angle. The rotary type belt conveyor comprises a conveyor body installed on a bracket; a conveying belt is matched with a conveying belt drive motor; the outer ring of a slewing bearing is connected to the bracket while the inner ring is connected to a pedestal through a bolt; a gear is matched with the outer teeth of the slewing bearing; a rotary motor is matched with the gear; the center shaft of the slewing bearing is connected to the spindle of an encoder; an angle controller is connected to the rotary motor through a wire for controlling starting, stopping and rotation direction of the rotary motor. The rotary type belt conveyor with the controllable angle provided by the invention is additionally provided with the slewing bearing, the encoder, the angle controller, the rotary motor and the gear on basis of the existing conveyor. The angle controller controls the starting, stopping and rotation direction of the rotary motor through electrical signals feed back from the encoder, and thereby accurately controlling the rotation angle of the conveyor. Therefore, the purpose of precise rotation angle and accurate directional material conveyance of the conveyor is achieved.

Split single-row ball slewing bearing

Abstract: The utility model discloses a split single-row ball slewing bearing which comprises an outer ring, an inner ring, a steel ball, a retainer and a sealing ring and is characterized in that the outer ring, the inner ring and the retainer are divided into two symmetrical halves, and the steel ball is placed in the retainer. According to the split single-row ball slewing bearing, a single-row ball slewing bearing is divided into two semicircular slewing bearings, each half slewing bearing serves as a whole and comprises the half inner ring, the half outer ring, a half isolation block, the half steel ball and the half sealing ring. During assembly, the two identical semicircular slewing bearings directly constitute the slewing bearing. In this case, since the inner ring, the outer ring and the retainer are divided into the two halves capable of being dismounted freely, the slewing bearing can be replaced or maintained simply and quickly without dismounting a whole upper rack and without limitation of fields.

L type welding tilter

Abstract: The utility model discloses a L type welding tilter, including the main tank body with set up the L type pivoting support at main tank side face, the main tank body is connected with L type pivoting support through slewing bearing, its characterized in that, slewing bearing's periphery is equipped with gear protection casing I, internal speed reducer support and the worm gear speed reducer machine I of being equipped with of main tank, the higher authority of the underframe of L type pivoting support is equipped with the connecting plate, is connected through little slewing bearing between the underframe of connecting plate and L type pivoting support, little slewing bearing's periphery is equipped with gear protection casing II. The utility model discloses the advantage that has is, can make the work piece be in the best manual weld position, can pinpoint, and it is dangerous can not take place the gliding, all install the gear protection casing in slewing bearing and little slewing bearing's periphery, emergence that like this can the to prevent accidental accident.

Excavate and load all -in -one

Abstract: The utility model discloses an excavate and load all -in -one, including last frame, lower frame, engine and torque converter, upward be equipped with the control chamber on the frame, the excavator device, be equipped with the loader device down on the frame, front axle and rear axle, front axle, rear axle is last to install preceding wheel respectively, the rear wheel, go up the frame and be connected through rotation mechanism between the frame down, rotation mechanism divides the oil gas electricity body including the center gyration, slewing bearing and slewing bearing seat, the center gyration divides the casing of the oil gas electricity body and last frame fixed mutually, center gyration divides the dabber of the oil gas electricity body to fix under on the frame, slewing bearing establishes on last frame, pivoting support seat establishes under on the frame, excavator device afterbody and slewing bearing relatively fixed, but the AND operation room is together for frame rotation down. Adopt behind the above -mentioned technical scheme, the utility model provides an excavate and load all -in -one can realize that 360 is rotatory for has possessed the excellent performance that excavator and loader have when having strengthened rotary working face totally.
