The invention discloses a diversion sheave installation structure for transforming a 1:1 elevator into a 2:1 elevator and a transformation method. The diversion sheave installation structure comprises an upper cross beam diversion sheave assembly and a rotary connection mechanism, and the upper cross beam diversion sheave assembly is connected to an upper cross beam of an elevator car through the rotary connection mechanism. The rotary connection mechanism comprises a connection screw rod, a thrust bearing and a nut. The upper cross beam is provided with an upper cross beam installation hole matched with the connection screw rod, the head of the connection screw rod is fixed on the upper cross beam diversion sheave assembly, the tail of the connection screw rod penetrates through the upper cross beam installation hole to be sequentially connected with the bearing and the nut, and the connection screw rod and the upper cross beam diversion sheave assembly can freely rotate by an angle together. The diversion sheave installation structure is used for transforming the elevator. The diversion sheave installation structure has the advantages that it is unnecessary to consider the relative position of the center of an old elevator car frame and the center of a counterweight, the field measurement difficulty is lowered, the design efficiency is improved, the standardized design is achieved, the extra steel wire rope service life loss caused by the increase of a rope deflection angle is reduced, and elevator vibration is reduced.
Description
technical field [0001] The invention relates to the technical field of elevator transformation. In particular, it relates to the technology of transforming a 1:1 elevator into a 2:1 elevator. Background technique [0002] Generally, when the original 1:1 hanging old ladder is transformed into 2:1 hanging, it is necessary to add a reverse rope pulley to the upper beam, and the main beam of the machine room is also required to be replaced. The vertical plane where the line connecting the center of the traction wheel of the main engine in the machine room and the center of the guide wheel should coincide with the vertical plane where the line connecting the rope outlet point of the counterweight corresponding to the guide wheel and the center of the car frame is located. It is difficult to stake out the ladder, and the settlement and deformation of the old building, the measurement error before the renovation and other reasons make the installation and positioning of the newly...
