Description

Technical Field

[0001] The utility model relates to the technical field of casings, outer covers and supports, in particular to an adjustable explosion-proof motor base. Background Art

[0002] Explosion-proof motors are a type of motor with explosion-proof performance. The measures taken include installing the electrical equipment cover in a casing that can withstand the explosion pressure of the internal explosive mixture, so that the live parts of the motor cannot produce sparks, arcs or dangerous temperatures that are sufficient to cause explosion hazards, or the live parts that may produce these phenomena are isolated from the explosive mixture so that they cannot contact each other or reach the level of explosion hazard (increased safety type, ventilation type, etc.).

[0003] For the stability of explosion-proof motors during use, they are generally installed on corresponding bases. The base plays the role of installing and fixing the explosion-proof motor and is an important accessory for explosion-proof motor installation. The bases of existing explosion-proof motors are generally steel plate brackets or steel plate concrete composite bases, and their shapes are generally fixed. Although they have high stability during use, there are often certain errors in the position of the motor installation during motor installation, resulting in the installed motor being unusable. When the position of the explosion-proof motor needs to be adjusted, all the bolts installing the explosion-proof motor need to be removed for adjustment, which is more troublesome and the operation process requires more manpower, thereby reducing installation efficiency.

[0026] (3) Beneficial effects

[0027] Compared with the prior art, the present invention provides an adjustable explosion-proof motor base, which has the following beneficial effects:

[0028] 1. The adjustable explosion-proof motor base can adjust the deviation of the explosion-proof motor in the up and down directions and the left and right directions when installing by rotating the threaded rod and the rotating shaft, so that the explosion-proof motor does not need to be repeatedly disassembled when installing, saving manpower while improving the efficiency of installing the explosion-proof motor, thereby increasing the practicality of the base.

[0029] 2. When the fan of the adjustable explosion-proof motor base is started, the fan starts to blow air upward, thereby driving air circulation through the connecting slot, and then synchronously driving air circulation around the explosion-proof motor on the second adjustment frame, thereby cooling the explosion-proof motor and preventing the high temperature of the explosion-proof motor from affecting its working performance, thereby increasing the practicality of the base.

[0030] 3. In the adjustable explosion-proof motor base, the limiting block and the limiting groove are matched to limit the second adjustment frame seat, so that the second adjustment frame seat can only move forward and backward, and cannot move up and down or left and right. This makes the front and rear displacement adjustment position of the explosion-proof motor more stable, and increases the stability of the base.

[0031] 4. The adjustable explosion-proof motor base mainly utilizes the self-locking property of the worm gear engagement by driving the worm to rotate, so that only the worm can drive the worm wheel to rotate, and the worm wheel cannot drive the worm to rotate. When the worm is no longer rotated, the worm wheel will also self-lock and will not rotate, thereby ensuring the stability and firmness of the explosion-proof motor after installation, thereby increasing the stability and firmness of the base.
