The elevator counterweight housing comprises a rack, at least one rope wheel and a counterweight block, the rack is internally provided with a containing space used for containing the counterweight block, the rope wheel is installed on a counterweight upper beam at the top of the rack and rotationally connected with the counterweight upper beam, one side of a rope wheel body is provided with a power generation module, the power generation module comprises a stator frame, and the stator frame is connected with the counterweight block. The stator frame is arranged on a wheel shaft of the rope wheel in a sleeving mode and rotationally connected to the wheel shaft of the rope wheel, a plurality of winding columns are evenly distributed on the outer side wall of the stator frame in the circumferential direction, coils are wound around the winding columns, a plurality of permanent magnets are evenly distributed on the edge of a wheel body of the rope wheel in the circumferential direction, the permanent magnets correspond to the winding columns, and a strain gauge is installed on the counterweight upper beam. According to the self-sufficiency counter-weight device, the strain gauges are matched with the power generation module, on one hand, the weight of the counter-weight block is monitored through the strain gauges, on the other hand, power is supplied to the strain gauges through self power generation of the power generation module, and in the whole process, mechanical energy of the rope wheel is converted into electric energy, so that self-sufficiency of the electric energy is achieved, and an external power source is not needed.
本发明公开一种电梯对重架,包括机架、绳轮和对重块,机架内设有用于放置对重块的容置空间,绳轮至少设有一个,所述绳轮安装在机架顶部的对重上梁上,并与对重上梁转动连接,绳轮轮体的一侧设有发电模块,发电模块包括定子架,定子架套装于绳轮的轮轴,并转动连接于绳轮的轮轴,定子架的外侧壁周向均布安装有多个绕线柱,绕线柱上环绕有线圈,绳轮轮体的边缘周向均布安装有多个永磁铁,永磁铁与绕线柱相对应,对重上梁上安装有应变片。本发明中,通过应变片和发电模块相配合,一方面利用应变片来监测对重块的重量,另一方面利用发电模块自发电来给应变片供电,在整个过程中,通过将绳轮的机械能转化为电能,以实现电能自给自足,无需使用外部电源。
