Abstract

PURPOSE:To prevent high contact pressure from being generated at a guide frame and a slide roller and also carry out smoothly the slide action of a slide frame by conducting the butting of a slide butting surface by surface contact in mutual operation with a guide surface, making the slide butting surface guided and supported. CONSTITUTION:A slide butting surface 54 is made by equipping a guide shoe unit 40 equipped with a guide shoe member 50 on a slide frame 30 side pivotingly attached with a tension pulley, and butts against the guide surface 24 of a guide frame 22 on a fixation side and is supported, and also is guided by it and slides back and forth. As a result, a contact area between the slide butting surface 54 and the guide surface 24 can be obtained large, so contact surface pressure is small, and accordingly, contact surface pressure between each other is low, and the wear and deformation of the guide frame 22 and the guide shoe member 50 are hard to be generated. Also, by using a friction reducing material for the slide butting surface 54 or the guide surface 24, a friction coefficient becomes small, and slide is carried out smoothly.

That is, there is a cableway equipment most widely used as a typical example of the rope-traction type suspended transportation equipment. A rope or a rope is used as a guideway and a traveling machine or a gripping rope having a traveling function and a rope connecting function. There is a group of crossing cableways that hangs the carrier on the machine and tows this carrier with tow lines and rolls the stanchions, double-track or three-line circulation cableway, and also functions as a guideway and pulls the carrier. There is a group of single-line circulation type cableways or double-type single-line circulation type cableways that use a towline that also has a function. In addition to this, as a transportation equipment very similar to cableway equipment, a suspension transportation equipment of the type that guides a carrier by using a rigid rail instead of the above-mentioned guideway as a guideway and tows with a tow rope is also implemented with a few examples or Proposed. The rope-pulling type suspended transportation equipment targeted by the present invention includes all of these.

EFFECTS OF THE INVENTION A tension device for a rope-pulling type suspension transportation facility such as a cableway has hitherto been compared with a guide frame which is a fixed side.
A configuration is generally used in which the sliding roller of the sliding frame on the moving side rolls and moves back and forth. Although the configuration of this prior art has the preferable advantage that the rolling friction resistance is small, the surface pressure of the contact between the sliding roller having a relatively small diameter and the guide frame is large, and the so-called Hertzian contact stress generated at the contact point is high, Therefore, wear of the sliding roller,
The guide rail was easy to wear and did not deform.

The tensioning device of the rope-pulling type suspension transportation equipment of the present invention comprises a sliding frame having a tensioning pulley pivotally mounted so as to be slidable along the guide rail and tensioned by the tensioning means. In order to balance the tension of the rope with a constant tension, in the present invention, the sliding frame side is provided with a guide shoe unit having a guide shoe member, and the sliding contact of the guide shoe member is made. A sliding member made of an antifriction material is attached to and abutted on either the surface or the guide surface of the guide rail on the fixed side so as to slide back and forth.

With this configuration, the contact area between the sliding contact surface and the guide surface is large and the contact surface pressure is small, and therefore the contact stress between them is low, and the guide rail and guide shoe members are less likely to wear or deform. . Moreover, since the sliding members made of the anti-friction material are used between them, there is an advantage that the friction coefficient is small and the sliding can be performed smoothly. In addition, since the support end of the support shaft is inserted into the hole of the guide shoe member in a substantially spherical shape, the guide shoe member follows the irregularities of the guide frame member and may cause some posture displacement. Even if it occurs, it can be smoothly adjusted by the centering action and smoothly slide.
