Abstract
The utility model discloses a motor operating mechanism applied to a high voltage isolating switch and a grounding switch. The motor operating mechanism comprises a stainless steel box body and a limiting and reduction mechanism, wherein the limiting and reduction mechanism is arranged in the box body and is composed of a motor, a worm gear reducer, a main shaft, crank arms, a mechanical limiting device, an electric limiting device, an auxiliary switch assembly and a travel switch. The motor is connected with an input shaft of the worm gear reducer. An output shaft of the worm gear reducer is connected with the main shaft. The crank arm which is arranged on the lower end of the main shaft is crimped on a top rod of the electric limiting device to cut off a control loop. The crank arm which is arranged on the upper end of the main shaft collides with the mechanical limiting device, so as to eliminate the motor inertia and ensure a reliable output angle. The auxiliary switch shaft is connected with the lower end of the output shaft of the worm gear reducer. The stainless steel box body is formed by riveting tension rivets. The motor operating mechanism has the advantages that by using the worm gear transmission, required torque and speed are output; the operating is stable; the impact force is small; the noise is low; the rotating angle of the auxiliary switch is almost consistent with the rotating angle of an output shaft of the mechanism; and the box body is in a stainless steel riveting structure, and has the reliable performances of water resistance, dust resistance, corrosion resistance and rusting resistance.
Description
Technical field
The utility model relates to the high-voltage electrical apparatus technical field, specifically a kind of high voltage isolator, earthed switch motor operating mechanism.
Background technology
Mostly high voltage isolator, earthed switch are to adopt by motor drive gear and worm gear reducer device with electric operating mechanism at present, give output shaft with the moment transmission behind double reduction; Auxiliary switch drives a cover connecting rod by mechanism's main shaft and switches; Casing is welded by steel plate or corrosion resistant plate.The problem that exists is as follows at present:
1. gear and worm gear reducer device be not owing to seal or machining accuracy, and noise is big when making mechanical operation;
2. auxiliary switch drives a cover connecting rod by mechanism's main shaft and switches; Make the corner of the corner of auxiliary switch and mechanism's output shaft inconsistent, reliability is relatively poor;
3. stainless casing becomes rusty and cause on the casing on rust or the weld seam because welding has destroyed stainless diaphragm.
Summary of the invention
In view of the deficiency that above-mentioned prior art exists, the purpose of this utility model provides a kind of corrosion-resistant, noise is little, reliability is high high voltage isolator, earthed switch motor operating mechanism.
The purpose of this utility model is achieved in that it comprises the stainless steel casing and places the spacing and reducing gear that is made of motor, worm type of reduction gearing, main shaft, connecting lever, mechanical stop limiter, electronic stopping means, auxiliary switch assembling and travel switch in this casing; Motor links to each other with the power shaft of worm type of reduction gearing; The output shaft of worm type of reduction gearing and main shaft are one, and promptly the output shaft of worm type of reduction gearing is main shaft; The connecting lever that is contained on the main shaft lower end is crimped on the electronic stopping means push rod, and the travel switch of electronic stopping means is switched, thereby cut off the control loop power supply, the contactor coil dead electricity, main contact disconnects and cuts off motor power, and motor stops the rotation.Be located at connecting lever and mechanical stop limiter collision on the main shaft upper end, eliminate the inertia of motor, thereby the angle of main shaft output is guaranteed at setting; The auxiliary switch assembling directly links to each other with the lower end of main shaft.
Described stainless steel casing links to each other with door by folding, and the stainless steel casing forms by the stretching rivet.
The utility model compared with prior art has following advantage:
1. utilize worm screw, worm-drive need to guarantee the commentaries on classics distance and the speed of output, make the smooth operation impulsive force little, noise is low;
2. the auxiliary switch axle directly links to each other with the lower end of worm reducer main shaft, and therefore, the corner of auxiliary switch almost is consistent with the corner of mechanism's main shaft.
Casing is the riveted stainless steel structure, and its good looking appearance, rational in infrastructure has reliable waterproof and dustproof, anticorrosion and anti-corrosion, compares with traditional Welding Structure, and is more light and handy and attractive in appearance.
Description of drawings
Fig. 1 is a box shape schematic diagram of the present utility model;
Fig. 2 is spacing and the reducing gear structural representation.
Embodiment
By accompanying drawing as can be known, this high voltage isolator, earthed switch comprise stainless steel casing 1 with the motor operating mechanism and place the spacing and reducing gear that is made of motor 5, worm type of reduction gearing 6, main shaft 7, connecting lever 9,12, mechanical stop limiter 13, electronic stopping means 8, auxiliary switch assembling 14 and travel switch 11 in this casing.Wherein the casing assembling is made of stainless steel casing 1 and door 2, folding 3 and stretching rivet 4.Stainless steel casing 1 is connected by folding 3 with door 2, and stainless steel casing 1 is riveted by stretching rivet 4 and formed (accompanying drawing 1).
Spacing and reducing gear is made of motor 5, worm type of reduction gearing 6, main shaft 7, connecting lever 9,12, mechanical stop limiter 13, electronic stopping means 8, auxiliary switch assembling 14 and travel switch 11.Motor 5 rotates, and drives main shaft 7 rotations that worm type of reduction gearing 6 rotates and is attached thereto, and the connecting lever 9 that is contained on the main shaft is crimped on the push rod 10 of electronic stopping means 8, and push rod 10 actions make travel switch 11 actions, cut off control loop.The connecting lever 12 that is contained in simultaneously on the main shaft impinges upon on the mechanical stop limiter 13, and motor stops, and mechanism is rotated in place.Switching comes reflected signal with main shaft 7 rotations in auxiliary switch assembling 14.
