Background
With the development of technology, the traction steel belt has been widely used as an elevator traction system by gradually replacing a steel wire rope due to the advantages of silence, attractive appearance, long service life, stable operation and the like compared with the traditional steel wire rope structure. The existing driving structure for dragging the steel belt mainly comprises a dragging shaft, dragging steel belt pulleys and dragging seats, wherein the dragging steel belt pulleys are arranged on the dragging shaft in parallel, two sides of the dragging shaft are rotationally connected with the dragging seats, the outside of the dragging seats is detachably connected with dragging machine bases, and two ends of the dragging shaft are respectively connected with a dragging machine and a brake. However, due to the structural characteristics of the traction steel belt, the requirement on the installation precision is higher compared with that of the traditional steel wire rope structure, and once the problem of inclination or left-right dislocation between traction steel belt wheels on two sides occurs, the traction steel belt cannot be installed, molded and stably driven. However, in the actual installation process, as the traction machine seat is directly hoisted to the top of the elevator shaft and then welded and formed, and finish machining treatment is not performed between each installation surface, the levelness and the position accuracy of the traction steel belt wheel after installation cannot be guaranteed to be completely consistent with those of the steel belt wheel on the lower car, and therefore manufacturers are required to adjust the levelness and the transverse position of the traction steel belt wheel according to the position of the external steel belt wheel.
To solve the above problems, the existing traction sheave structure is divided into two types, the first is that the traction sheave structure is integrally formed by a traction steel belt wheel and a traction shaft and is mounted on a traction seat together, so that the transverse position and levelness of the traction seat are integrally changed during adjustment. However, the traction sheave structure not only has the problem of difficult displacement of the traction sheave, but also can not simultaneously consider the transverse position and levelness of the traction sheave in the moving process, thereby reducing the positioning accuracy of the traction steel belt wheel. The second is to drag the steel band pulley and drag the axle and be split type setting and transmission connection for drag the steel band pulley and can drag epaxial lateral shifting and carry out the position adjustment, but this structure is difficult to adjust the levelness of dragging the seat equally on the one hand, on the other hand then causes the steel band pulley to drag the horizontal drunkenness after the location easily, has increased the possibility of dragging the steel band and warp the deformation in the use promptly.
Therefore, the conventional traction sheave structure for the traction steel belt has problems of difficult installation and low positioning accuracy.
