Description

Technical Field

[0001] The utility model relates to the technical field of emulsion pump equipment, in particular to a quick installation and release mechanism for an emulsion pump motor in an underground coal mine. Background Art

[0002] There are two ways to install the emulsion pump in the emulsion pump group and the explosion-proof motor for underground coal mines, one of which is the flange frame concentric shaft type and the other is the parallel shaft type.

[0003] Among them, the flange frame concentric shaft type has the characteristics of easy centering and high concentricity, but it is difficult to connect the stoppers during installation. When replacing the coupling underground in the coal mine, it is difficult to disengage the motor. It is also difficult to install after replacing the coupling. More than three people and 4 sets of hand hoists are needed to adjust the balance of the motor to complete this task. In addition, the hand hoist must be hung on the anchor rod at the top of the tunnel. When the motor is disengaged, there is uncontrollable hanging swing. The greater the motor power and the heavier the weight, the more likely it is to cause personal injury. There are great safety hazards and safety accidents.

[0004] In order to solve the above problems, people have been seeking an ideal technical solution. Summary of the invention
