The invention relates to a manufacturing method of the detachable fixing part of an elevator protective door. The elevator protective door comprises the fixing part and a rotating part, wherein the fixing part is composed of a left semicircular hoop, a right semicircular hoop, a rotating shaft and a bayonet connecting bolt, the left semicircular hoop and the right semicircular hoop are equal in height and diameter, one end of the left semicircular hoop and one end of the right semicircular hoop are connected with the rotating shaft, the other end of the left semicircular hoop and the other end of the right semicircular hoop respectively bend outwards to form a connecting plate, a U type groove is formed in the middle close to the top of the left connecting plate, a connecting hole corresponding to the U type groove is formed in the center of the right connecting plate, and the bayonet connecting bolt is sequentially inserted in the connecting hole through the U type groove and fastened through a nut to form fastening connection with a stand column. The rotating part is composed of a sleeve and an insertion, the insertion is composed of an inserting section and a protective door connecting section, the sleeve is welded to the outer side face in the middle of the left semicircular hoop, the inserting section of the insertion is inserted into the sleeve and can rotate freely, and the protective door connecting section is connected with a frame of the protective door in a welded mode. The detachable fixing part has the advantage of being convenient to assemble and disassemble, and can be widely applied to high-rise building construction.
Description
technical field [0001] The invention relates to a method for manufacturing a fixing part between an elevator protective door and a column in the construction of high-rise and super high-rise buildings, in particular to a method for manufacturing a detachable fixing part between an elevator protective door and a column. Background technique [0002] Construction elevators are essential construction equipment for vertical transportation during the construction of high-rise buildings. The elevator protective door is a necessary facility to ensure the safety of construction personnel during the construction of high-rise buildings. The finished spring connector or hinge is usually used between the elevator protective door and the column. Connecting parts, the cost of the finished connecting parts is relatively high, and they are generally conjoined, which is inconvenient to assemble and disassemble, and is not conducive to the turnover of the protective door; or use steel bars to...
