Description

Technical Field

[0001] The present application relates to the technical field of explosion-proof motors, and in particular to an explosion-proof motor that is convenient for maintenance. Background Art

[0002] An explosion-proof motor is a type of motor that can be used in explosive and flammable environments and does not generate electric sparks during operation. Explosion-proof motors are mainly used in coal mines, oil and natural gas, petrochemical, and chemical industries. In addition, they are also widely used in textile, metallurgy, city gas, transportation, grain and oil processing, paper making, medicine and other sectors. As the main power equipment, explosion-proof motors are usually used to drive pumps, fans, compressors, and other transmission machinery.

[0003] An explosion-proof motor mainly includes a stator, a rotor, and a housing. The stator and the rotor are both installed inside the housing, and the housing supports and protects the stator and the rotor. The housing generally includes a housing body, a front end cover, and a rear end cover. The front end cover and the rear end cover are respectively fixedly installed at both ends of the housing body. When the explosion-proof motor needs to be maintained, generally, the housing is disassembled, and then the stator and the rotor are taken out from the inside of the housing body for maintenance.

[0004] There is a Chinese patent with the authorization announcement number CN220254259U, which discloses an explosion-proof motor that is convenient for maintenance, including a housing body. At both ends of the housing body, a shaft extension end cover and a tail end cover are respectively installed. Inside the housing body, there is a rotor, and on the rotor, there is a rotating shaft that rotates through the shaft extension end cover. At the front end of the housing body, there is an arc-shaped opening, and at the arc-shaped opening, an arc-shaped cover plate is hingedly installed. The arc-shaped cover plate fits with the arc-shaped opening. On the circumferential outer wall of the housing body near the tail end cover, a rotating ring is rotatably sleeved, and at one end of the rotating ring facing the shaft extension end cover, there is an arc-shaped clamping plate.

[0005] When maintaining the above-mentioned explosion-proof motor that is convenient for maintenance, rotating around the hinge at the bottom of the arc-shaped cover plate, the arc-shaped cover plate is moved away from the arc-shaped opening, and the staff reaches into the housing body through the arc-shaped opening to maintain the rotor.

[0006] When maintaining the above-mentioned explosion-proof motor that is convenient for maintenance, the explosion-proof motor needs to be flipped, and then, the explosion-proof motor is maintained through the arc-shaped opening. However, the flipped explosion-proof motor has the defect of being difficult to stably support. Utility Model Content

Detailed Description of the Invention

[0028] The following will further elaborate on the present application Figures 1-3 with reference to the accompanying drawings.

[0029] An embodiment of the present application discloses an explosion-proof motor that is convenient for maintenance.

[0030] An explosion-proof motor that is convenient for maintenance includes a housing 1, a protection plate 2, and a support member 3. An inspection port is provided at the bottom of the housing 1, and a placement groove 11 is provided at the top of the outer peripheral surface of the housing 1. The protection plate 2 is installed at the inspection port through bolts, and the support member 3 is installed on the protection plate 2.

[0031] When the explosion-proof motor is working normally, the protection plate 2 is installed at the inspection port, and the support member 3 provides auxiliary support for the explosion-proof motor to further improve the working stability of the explosion-proof motor. When the explosion-proof motor needs to be repaired, the protection plate 2 at the inspection port is removed and placed in the placement groove 11. Then, the explosion-proof motor is turned over, and the explosion-proof motor is supported by the support member 3. The staff repairs the internal components of the explosion-proof motor through the inspection port.

[0032] To facilitate the installation of the protection plate 2, an installation groove is provided at the inspection opening. The protection plate 2 is installed at the installation groove, and the protection plate 2 is positioned and installed through the installation groove.

[0033] The support member 3 includes a mounting seat 31 and a telescopic cylinder 32 installed on the protection plate 2. The mounting seat 31 is fixedly installed on the side of the protection plate 2 away from the housing 1.

[0034] The telescopic cylinder 32 includes a reference cylinder 321, an adjustment cylinder 322, a limiting member 323, and a support unit 324. The reference cylinder 321 is fixedly installed on the mounting seat 31. The adjustment cylinder 322 is slidably installed inside the reference cylinder 321. The limiting member 323 is installed between the reference cylinder 321 and the adjustment cylinder 322. The limiting member 323 is used to limit the adjustment cylinder 322. The support unit 324 is fixedly installed at the bottom end of the adjustment cylinder 322.

[0035] Both the reference cylinder 321 and the adjustment cylinder 322 are rectangular cylinders. A storage space is formed inside the reference cylinder 321 and the adjustment cylinder 322. A placement hole 328 is provided on the side wall of the adjustment cylinder 322, facilitating the staff to place tools inside the storage space through the placement hole 328, thereby improving the convenience of overhauling the explosion-proof motor.

[0036] The reference cylinder 321 is provided with a limiting hole 325. A plurality of limiting holes 325 are provided on the side wall of the adjustment cylinder 322 along the vertical direction of the adjustment cylinder 322. The limiting member 323 includes a limiting rod, and the limiting rod is inserted and matched with the limiting hole 325. When it is necessary to adjust the overall length of the telescopic cylinder 32, the limiting rod can be inserted and matched with the limiting holes 325 at different positions.

[0037] The support unit 324 includes a support plate 326 and a support rod 327. The support plate 326 is fixedly installed at the bottom end of the adjustment cylinder 322 to improve the support stability of the explosion-proof motor. When placing the support plate 326, the support rod 327 is inserted into the ground to further improve the stability of the support plate 326. When the explosion-proof motor is working normally, the support rod 327 inserted into the ground further improves the stability of the explosion-proof motor.

[0038] The implementation principle of an explosion-proof motor convenient for maintenance in an embodiment of the present application is as follows: When the explosion-proof motor is working normally, the explosion-proof motor is supported by the support plate 326 to improve the working stability of the explosion-proof motor. When the explosion-proof motor needs to be maintained, the protection plate 2 is removed and placed in the placement groove 11. Then, the explosion-proof motor is flipped, and the explosion-proof motor is supported by the support plate 326 and the support rod 327. The staff can maintain the explosion-proof motor through the maintenance port. The reference cylinder 321 and the adjustment cylinder 322 form a storage space, which is convenient for placing tools inside the storage space and improving the convenience of maintaining the explosion-proof motor. When the overall length of the telescopic cylinder 32 needs to be adjusted, the limit rod can be inserted into different limit holes 325, which improves the convenience of adjusting the overall length of the telescopic cylinder 32.

[0039] The above are all preferred embodiments of the present application. Without limiting the protection scope of the present application accordingly, therefore: Any equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
