Abrégé

The present invention relates to a rubberized fabric article-covered elevator balance compensation chain, comprising a connection plate frame, hinge leaves, and a recess. Positioning bolts are disposed at an upper and lower side of the connection plate frame. A connection bar is disposed at one side of the connection plate frame, and a movable frame is disposed within the connection bar. A rotating disk is disposed at one side of the movable frame. A link is disposed at an inner side of the connection bar, and a rubberized fabric article is disposed within the link. The present invention provides an advantageous effect by effectively connecting, by means of an adhesive, the rubberized fabric article and a wrapped rubberized fabric strip between links, rubber-dipping an elevator compensation balance chain fiber cloth, forming a semi-finished product by forming a molded metal anchor chain wrapped with a layer of the rubberized fabric article and the wrapped rubberized fabric strip, and performing, by means of a vulcanizer, vulcanization to produce a product. In the vulcanization process, air evacuation is performed on the product so as to ensure a product wrapping effect. In the wrapping process, a rubberized textile article is cut into the rubberized fabric article and the wrapped rubberized fabric strips so as to obtain wrapping at a specific angle, thereby maintaining the strength of the fabric while reducing material waste.

An X-ray mapping-based automatic anchor chain detection system, which belongs to the field of elevators, may achieve the automatic detection of elevator balance compensation chains, and may at the same time detect multiple defects such as false welding, cracks, bumps, and deformation, instead of a manual visual inspection method. Not only may the detection accuracy be improved, but the working efficiency may also be improved. Welding appearance quality problems may automatically be identified by means of an X-ray imaging module (100), an image transmission module (200), an image comparison module (300), a processing module (400), a self-learning module (500) and a computer (600), and automatic detection is more reliable and stable than the current detection method, and also reduces the workload of the workers and improves the working efficiency of the detection. A shift lever (10) is driven by means of a roller (9) to rotate, and the shift lever (10) moves an anchor chain to travel forward so as to implement the automatic travelling of the anchor chain, so that the electrically welded anchor chain may uniformly pass ray detection and misidentification, and one or more chains may pass through a scanning region at the same time, and complete scanning detection at the same time.

A one-time rapid method for use in molding a plastic coating of an elevator balance compensation chain, comprising the following steps: compounding and mixing a polymer material; pressing and shearing the polymer material; extruding and heating the pressed and sheared polymer material to form a viscous flow; causing the polymer material having a viscous flow to enter a main channel to form an initial wrapping effect on an anchor chain; the polymer material then sequentially entering auxiliary channels within a mold set to multi-directionally wrap the anchor chain in material from a plurality of segment surfaces, respectively, so as to form a uniform wrapping layer; finally cooling and molding. The method alters the traditional method of extruding and wrapping by means of multiple single-screws at separate working sections and secondary heating, employing a method of single-screw one-time extrusion molding and one-time heating, thereby preventing the aging of a polymer material which is caused by repeated heating, and extending the service life of the polymer material and elevator balance compensation chains, while reducing investments in manpower, equipment, energy and time.
