Description

Belt type elevator having a pulley module The present invention relates to a belt-type elevator that uses a belt instead of a rope, and more specifically, to a belt-type elevator improved to facilitate maintenance of the belt pulley. Conventionally, it was common practice to use a steel rope made by twisting multiple strands of steel wire to drive the elevator car; however, providing sufficient contact friction on the hoisting side required a relatively large capacity motor and sheave, necessitating an overall large scale of facilities including the machine room. Accordingly, belt elevators such as those disclosed in Patent Registration No. 10-0567688, Patent Registration No. 10-2468213, Patent Registration No. 10-2548320, etc., have been proposed as a method to eliminate the machine room or reduce the overall size of the facility while providing sufficient contact friction. In such belt-type elevators, the pulley is an important component along with the belt; however, in previously proposed inventions regarding belt-type elevators, no invention or idea has been proposed that focuses on the efficiency of maintenance of the pulley, particularly the work of replacing the pulley with a new one. For example, the aforementioned Patent Registration No. 10-0567688 and Patent Registration No. 10-2548320 only propose a concept for a belt-type elevator, from which specific maintenance measures cannot be derived, and the aforementioned Patent Registration No. 10-2468213 only proposes a configuration that excludes the use of pulleys. FIG. 1 is a perspective view illustrating a body of a belt-type elevator according to an embodiment of the present invention. FIG. 2 is a perspective view showing only the upper body separated from the body of FIG. 1. FIG. 3 is a perspective view showing only the pulley module separated from the upper body of FIG. 2. FIG. 4 is an exploded perspective view showing the upper body and pulley module separated from FIG. 2. FIG. 5 is a perspective view illustrating a counterweight of a belt-type elevator according to an embodiment of the present invention. FIG. 6 is a perspective view illustrating the main configuration of a machine room of a belt-type elevator according to an embodiment of the present invention. A belt-type elevator according to an embodiment of the present invention includes a frame (10) on which an elevator car is mounted, as shown in FIG. 1. In particular, in an embodiment of the present invention, the upper body (100) constituting the upper part of the body (10) comprises a front frame (110) and a rear frame (120) arranged parallel to each other with a certain distance between them in the front and rear as shown in FIG. 2, a pair of left and right side frames (130, 140) that are fastened to both left and right ends of the front frame (110) and the rear frame (120) to form a square frame overall, and a pair of left and right reinforcing members (150, 160) that are positioned between the pair of side frames (130, 140) and have their front and rear ends fastened to the front frame (110) and the rear frame (120). In the upper body (100) of this structure, a pulley module (200, 200') is inserted and connected between the pair of side frames (130, 140) and the pair of reinforcing members (150, 160) respectively so as to be removable via bolt fastening. As shown in FIG. 3, the pulley module (200) is equipped with a C-shaped support bracket (201), a pulley (240), and a pair of shaft support plates (250, 260). The support bracket (201) has a pair of rectangular bearing plate sections (210, 220) arranged parallel to each other with a certain spacing between them, an intermediate plate section (230) connecting the pair of bearing plate sections (210, 220), and U-shaped shaft insertion holes (212, 222) formed by being recessed through each side (211, 221) of the pair of bearing plate sections (210, 220). The pulley (240) has shafts (241, 242) at both ends inserted through shaft insertion holes (212, 222) formed in the pair of bearing plate portions (210, 220), and the pair of shaft support plates (250, 260) are bolted to the inner surface of the pair of bearing plate portions (210, 220) and support the lower half of the shafts (241, 242) inserted into the shaft insertion holes (212, 222) through a semicircular shaft support groove (251, etc.) formed in the upper part. The upper half of the shafts (241, 242) is supported by the upper part of the U-shaped shaft insertion holes (212, 222) mentioned above. As shown in FIGS. 2 and 4, the pulley module (200, 200') configured as described above has the pair of bearing plate portions (210, 220) in surface contact with the back of the front frame (110) of the upper body (100) and the front of the rear frame (120), and is fastened so as to be detachable by bolt fastening. In order for the pulley (240) to rotate smoothly in this fastened state, as illustrated in relatively detail in FIG. 3, it is preferable that each axial end surface (241a, etc.
