The elevator heavy hammer guide pipe comprises a rectangular pipe body and composite parts, the rectangular pipe body is defined by rolling an iron plate, the two ends of the iron plate are provided with the composite parts which surround the pipe body into a closed shape, and the composite parts are formed by fusing plastic and the iron plate through a co-extrusion technology; the composite pipe has the advantages that the pipe body material is formed by rolling the iron plate, and the pipe body is enclosed into a closed shape through the composite part formed by fusing plastic and the iron plate, so that the strength and rigidity of the pipe body are improved, the problems of flame retardance, fire prevention and high temperature resistance are solved, the weather resistance is greatly enhanced, the pipe body is fixed and reinforced, and the service life of the pipe body is prolonged. Meanwhile, the friction force generated when the heavy hammer slides up and down in the guide pipe is relieved, noise caused by friction between the heavy hammer and the guide pipe is reduced, and the shockproof and soundproof effects are achieved.
本发明公开了一种电梯重锤导管,包括长方形管体和复合部,所述长方形管体由铁板滚压围成,在所述铁板的两端设置有将所述管体围成闭合状的复合部,所述的复合部是通过共挤工艺将塑料与所述的铁板融合构成的;优点在于将管体材料改为由铁板滚压而成,并通过塑料和铁板融合而成的复合部将管体围成闭合状,不仅提高了管体的强度和刚性,解决了阻燃防火和耐高温问题,大大增强了耐候性能,且对管体起到固定和加强作用,同时缓减了重锤在导管内上下滑动产生的摩擦力,降低了两者摩擦引起的噪声,起到了防震和隔音的效果。
