Abstract

一种涉及手动起重葫芦的锥体离合片限载装置,其技术要点在于制动螺母(1)右端轴档上装有换向棘轮(3),在换向棘轮(3)左侧分别套上离合片(4)、滑片(5)、离合片(6)、蝶形弹簧(7),当重物超载时,制动螺母(1)与换向棘轮(3)的圆载面摩擦打滑,又换向棘轮(3)、离合片(4)、滑片(5)及离合片(6)之间的平面摩擦打滑,使载荷得到限制,手动起重葫芦达到限载的目的,克服了过去手动超重葫芦无限载装置给设备和人身常造成伤害事故的缺点。
The utility model relates to a conic clutch plate load limiter of a hand-operated hoister. The technical proposals of the utility model lies in that a reversing ratchet wheel (3) is arranged on a shaft gear at the right end of a brake nut (1); the left side of the reversing ratchet wheel (3) are respectively sheathed with a clutch plate (4), a slide plate (5), a clutch plate (6) and a butterfly spring (7); when a weight excesses a load, the circular loading surfaces of the brake nut (1) and the reversing ratchet wheel (3) slip by friction, and plane surfaces among the reversing ratchet wheel (3), the clutch plate (4), the slide plate (5) and the clutch plate (6) slip by friction; the load is restricted, the hand-operated hoister achieves the purpose of limiting the load, and the defect that the past hand-operated hoister is not provided with a load limiter so as to frequently bring injury accidents to equipment and persons is overcome.
