An explosion-proof motor with a protective structure

Abstract

The invention discloses an explosion-proof motor with a protective structure, which belongs to the technical field of explosion-proof motors. The motor comprises a base and a connecting block fixedly installed at the top of the base near the left side. Through the mutual cooperation among the components such as a fixing plate, a hydraulic cylinder, a clamping block, a clamping plate, a thermistor, an electromagnet, a magnet block, a telescopic spring, a T-shaped pressing block, a position sensor and a switch, the temperature of the motor body during use can be monitored through the setting of the thermistor. When a failure occurs and the temperature is abnormal, the T-shaped pressing block will be driven to move and contact the switch, so that the motor body can be stopped, which is beneficial for staff to detect and repair the motor in time and improve the use effect. At the same time, the hydraulic cylinders on both sides can be driven to operate, so that the clamping plate can be driven to clamp the output shaft of the motor body to achieve fixation, so as to avoid the output shaft from continuing to rotate due to inertia when a failure occurs in the motor body, thereby improving the safety of use.

Description

Technical Field

[0002] An explosion-proof motor is a motor that can be used in flammable and explosive places. It does not generate electric sparks during operation. It is mainly used in coal mines, oil and gas, petrochemical and chemical industries. In addition, it is also widely used in textile, metallurgy, urban gas, transportation, grain and oil processing, papermaking, medicine and other departments. As the main power equipment, explosion-proof motors are usually used to drive pumps, fans, compressors and other transmission machinery.

[0046] Working principle: When in use, the operation of the motor body 6 can drive the external equipment to operate, and the operation can make the drive motor B974 operate. When the drive motor B974 is in operation, it will drive the reciprocating screw 973 to rotate through the rotating shaft. When the reciprocating screw 973 rotates, it will drive the screw nut 972 to move back and forth. When the screw nut 972 moves backward, it will drive the movable plate 97 to move backward through the vertical rod 971, and when the movable plate 97 moves backward, it will drive the T-shaped plug plate 96 to move in the piston cylinder 95, so that the coolant in the coolant tank 93 can be sucked into the piston cylinder 95, and when the movable plate 97 moves forward, it will drive the T-shaped plug plate 96 to move forward in the piston cylinder 95, so that the coolant can be transported to the cooling ring 91, thereby reducing the motor cost. The temperature around the motor body 6 is affected by the heat dissipated by the motor body 6 when it is working, and water droplets will be generated when it contacts the outer side of the cooling ring 91. Then the driving motor A81 and the cooling fan 89 can be operated. When the driving motor A81 is in operation, it will drive the rotating rod to rotate. When the rotating rod rotates, it will drive the transmission gear 82 to rotate. When the transmission gear 82 rotates, it will drive the gear ring 83 to rotate. When the gear ring 83 rotates, it will drive the rotating plate 84 to rotate on the inner wall of the protective shell B4. When the gear ring 83 rotates, it will drive the wiping sponge plate 85 to rotate synchronously, so as to wipe the water droplets on the outer side of the cooling ring 91. At this time, when the rotating rod rotates, it will also drive the screw 86 to rotate through the belt B87. When the screw 86 rotates, it will drive the threaded sleeve B88 to move back and forth and left and right. When the motor body 6 is in an abnormal temperature state, the resistance of the thermistor 75 will decrease, thereby increasing the current. At this time, the magnetic repulsion between the electromagnet 76 and the magnet block 77 will increase, so the magnet block 77 will be pushed to the left. When the magnet block 77 moves, it will drive the T-shaped pressing block 78 to move. When the T-shaped pressing block 78 moves, it will contact the switch 79, thereby stopping the motor body 6. At the same time, the position sensor 781 will detect the movement of the T-shaped pressing block 78 and transmit the signal to the controller. At this time, the controller will control the liquid pressure on the front and rear sides. When the hydraulic cylinder 72 is running, the clamping block 73 will be driven to move relative to it, and the clamping block 73 will be driven to move relative to it when it moves relative to it, thereby clamping and locking the output shaft of the motor body 6 to prevent the motor body 6 from stopping due to a fault, while the conveying shaft continues to rotate under the action of inertia. In an emergency, the knob 531 is turned again to drive the front threaded rod 53 to rotate, and the front and rear threaded rods 53 will be driven to rotate synchronously through the transmission of the belt A532. When the threaded rod 53 rotates, the adjacent threaded sleeve A52 will be driven to move to the right synchronously. When the threaded sleeve A52 moves to the right, it will drive the protective shell B4 to move to the right through the connecting rod 51, so that the motor body 6 is exposed to the outside, which is beneficial for the staff to inspect and repair the motor body 6.

[0047] The wiring diagram between the thermistor 75, electromagnet 76, magnet block 77, position sensor 781, drive motor A81 and drive motor B974 and the controller in the present invention is common knowledge in the field, and its working principle is a well-known technology.
