[0002] The compensation chain (cable) is an elevator component that balances the weight of the traction wire rope. The load-bearing structure of the existing compensation chain (cable) is made of ordinary steel. In coastal areas, the iron chain is easily corroded by the air, and even rusted and broken. Rubber is easy to age, which brings safety hazards

Embodiment 1
[0020] The aging-resistant elevator compensation cable preparation process includes the following steps:
[0021] The first step: galvanizing aviation steel wire ropes or compensation chains, coating the surface of several aviation steel wire ropes or compensation chains with an ultra-thick zinc layer of 265-290g / m², and the preferred thickness of the zinc layer is 270, 276, 280, 285 g / m2 ;
[0022] The second step: winding, the aviation steel wire rope obtained in step 1 is wound into a steel wire rope core by a winding machine, and the wound steel wire rope core is placed in an anti-rust oil tank for 15-35 minutes to ensure that the cuts of several aviation steel wire ropes are covered with anti-rust Rust oil, the immersion time is 16, 18, 22, 25 and 30 minutes, and the anti-rust oil coated inside the cut of some aviation wire ropes is basically saturated;
[0023] The third step: put on the corrosion-resistant rubber sheath, and put the corrosion-resistant rubber sheath on...
Embodiment 2
[0028] The aging-resistant elevator compensation cable preparation process includes the following steps:
[0029] Step 1: Galvanize aviation steel wire ropes or compensation chains, and coat several aviation steel wire ropes or compensation chains with an ultra-thick zinc layer of 285g / m²;
[0030] The second step: winding, the aviation steel wire rope obtained in step 1 is wound into a steel wire rope core by a winding machine, and the steel wire rope core obtained by winding is soaked in an anti-rust oil tank for 30 minutes to ensure that the cuts of several aviation steel wire ropes are covered with anti-rust oil;
[0031] The third step: put on the corrosion-resistant rubber sheath, and put the corrosion-resistant rubber sheath on the steel wire rope core or the compensation chain jacket;
[0032] The fourth step is to coat the PP sheath, and use the plastic coating process to apply the PP material to the outside of the corrosion-resistant rubber sheath to form a 01.5mm PP...

Abstract
The invention discloses a preparing technology for an anti-ageing elevator compensation cable. The preparing technology comprises the following steps that firstly, a plurality of aviation steel wire ropes or compensation chains are plated with zinc, wherein the surfaces of the aviation steel wire ropes or compensation chains are plated with the super-thick zinc layers at 265-290 g / m<2>; secondly, winding is carried out, wherein the aviation steel wire ropes obtained in the first step are wound into a steel wire rope core through a winding machine, and the steel wire rope core is put into an anti-rusting oil trough to be soaked for 15-35 min; thirdly, a corrosion-resistant rubber sheath is arranged in a sleeving mode; fourthly, a PP protection layer is smeared, wherein a PP material is smeared to the outer part of the corrosion-resistant rubber sheath with the plastic coating technology, the PP protection layer with the thickness of 0.3-1.5 mm is formed, and supra polymer polyvinyl chloride with the weight percentage of 18-23% is added into the PP material in the plastic coating technology. The corrosion resistance and the anti-ageing property of the compensation cable prepared through the technology are improved, the stable performance of the product is maintained in the harsh environment with strong ultraviolet while various physical indexes in the conventional environment are ensured, the service life is prolonged, and the safety is improved.
Description
technical field [0001] The invention relates to the technical field of elevator compensation cables, in particular to the technical field of manufacturing technology of elevator compensation cables and the preparation process of aging-resistant elevator compensation cables. Background technique [0002] The compensation chain (cable) is an elevator component that balances the weight of the traction wire rope. The load-bearing structure of the existing compensation chain (cable) is made of ordinary steel. In coastal areas, the iron chain is easily corroded by the air, and even rusted and broken. Rubber is easy to age, which brings safety hazards. Therefore, our company has developed an anti-aging and anti-corrosion elevator compensation cable product. Contents of the invention [0003] In order to overcome the deficiencies in the prior art above, the present invention provides a preparation process for aging-resistant elevator compensation cables, the purpose of which is t...
