Embodiment Construction

[0020] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0021] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

Abstract

The invention relates to a tension device which comprises a sliding assembly and a tension frame, wherein the sliding assembly comprises fixing guide rails and sliding guide pieces; the sliding guide pieces slide relative to the fixing guide rails; the tension frame is fixedly connected to the sliding guide pieces, is used for mounting of a step chain or a pedal chain, and performs reciprocating motion along the fixing guide rails through the sliding guide pieces to absorb the elongation of the step chain or the pedal chain. The tension device has the advantages that the tension frame is used for mounting of the step chain or the pedal chain, is fixedly connected to the sliding guide pieces, performs the reciprocating motion along the fixing guide rails through the sliding guide pieces to absorb the elongation of the step chain or the pedal chain, and does not rotate, so that the stress of the tension frame is relatively low, the strength required by the tension frame is relatively low, and the tension frame can be made of less materials. Therefore, the manufacturing cost of the tension device is reduced.

Description

technical field [0001] The invention relates to the technical field of escalators and moving walks, in particular to a tensioning device. Background technique [0002] With the continuous development of society, escalators and moving walks are widely used in buildings, bringing great convenience to people's lives. Traditional escalators or moving walks use sprocket-type step chain tensioners or pedal chain tensioners. After the sprocket-type step chain tensioner or the sprocket-type tensioner in the pedal chain tensioner makes the chain obtain initial tension, adjust the position of the steering guide rail through its free sliding on the fixed guide rail to absorb the tension of the chain on the ladder. Telescopic length on the way. At the same time, the tooth slots of the sprocket installed on the sprocket tensioner mesh with the chain roller or roller, and the chain drives the sprocket to rotate around the axis to realize the steering of the step chain or the pedal chain...
