Traction structure of an outdoor elevator

Abstract

The invention relates to the field of manufacturing of elevators and particularly relates to a dragging structure for an outdoor elevator. The dragging structure disclosed by the invention comprises a novel dragging wheel, a connecting shaft, and a main wheel which is connected to the connecting shaft, wherein a dragging rope is connected to the main wheel; the dragging structure also comprises a fixing device, a wheel stabilizing device and a detecting device, wherein the fixing device leans against the main wheel and is used for fixing the position of the main wheel on the connecting shaft; the wheel stabilizing device is used for preventing side lurch of the main wheel; the detecting device is used for testing the tensile force of the dragging rope; the connecting shaft is provided with length range scales and a plurality of positioning holes. The invention aims to provide the dragging structure for the outdoor elevator; according to the dragging structure, the distance among a plurality of dragging wheels is adjustable; precise reading is realized; horizontal stability is realized; the tensile force changes of the dragging rope can be detected in the first time; besides, the dragging structure has filtration, shock absorption and heat insulation effects.

Description

technical field [0001] The invention relates to the field of elevator manufacturing, in particular to a traction structure of an outdoor elevator. Background technique [0002] As a common vertical lifting tool, traction elevators are widely used in large commercial buildings or office buildings. Compared with hydraulic elevators, traction elevators have the advantages of high transmission height, high acceleration, and rapid lifting. The use range of traction elevators is also very large. widely. [0003] The traction elevator is different from the hydraulic elevator, its power source comes from the counterweight and the traction device, and the traction device includes a traction wheel, such as the traction wheel disclosed in the patent document with the authorized announcement number CN202912536U, which includes a rope groove, There is a special design for the rope groove, which can detect the amount of wear. [0004] However, the traction sheave and the traction rope a...

[0004] However, the traction sheave and the traction rope are important safety components of the elevator. In recent years, higher requirements have been put forward for its detection, accuracy and safety. The installation position of the traction wheel will also be different, and the existing traction sheave is not installed accurately; in addition, the tension of a certain traction rope in the traction sheave may be weakened, causing a safety hazard; finally, due to multiple traction ropes The uneven tension between them will produce a horizontal offset force on the traction sheave itself, resulting in the inclination or even displacement of the traction sheave

[0005] On the other hand, when the traction elevator is used outdoors, it is exposed to the sun for a long time, causing the temperature in the shaft wall of the outdoor elevator to be too high, which in turn affects the air in the shaft and the riding experience in the elevator box
