The invention discloses a simple pin shaft mounting and dismounting support and a mounting and dismounting method, and relates to a first component to be mounted, a second component to be mounted and a pin shaft, the support comprises a first support body, a second support body, a chain block, a lifting bolt and fixing plates, threaded holes are formed in the fixing plates, and the fixing plates are welded to the two sides of a pin hole of the first component to be mounted; the first support and the second support are both of an n-shaped structure, C-shaped frames are arranged at the closed ends of the first support and the second support, through holes are formed in the C-shaped frames, and the open ends of the first support and the second support are connected with a fixing plate welded to the first component. The chain block is mounted on the bracket II; a threaded hole is formed in the end of the pin shaft, the pin shaft is installed on the first support, the end of the pin shaft is connected with the first support, and the other end of the pin shaft is connected with the chain block. When the pin shaft is pulled in from high altitude, the pin shaft is inserted into a single-side shaft hole of the first component, and the pin shaft is hoisted in place along with the first component; when the pin shaft is detached, the second support is installed on the pull-out side, and the pin shaft is pulled out through the chain block. The support is simple in structure and low in cost, and the problem that high-altitude mounting and dismounting of the large-diameter pin shaft are difficult is solved.
