The invention discloses a chain block with a load limiting function, which relates to the technical field of hoisting machinery and comprises a block mechanism. According to the chain block with the load limiting function, through the design of a block mechanism, a manual lock chain is pulled to control a composite mechanism to lift materials, the manual lock chain rotates on the surface of a friction mechanism, and a cover plate is connected with a silica gel block to cover and shield the manual lock chain, so that the movement space of parts is limited, and the situation that the manual lifting effect is affected due to torsion is avoided; the silica gel blocks are made of silica gel materials, and silica gel has certain attachment and damping performance, so that the effects of reducing collision of parts, reducing abrasion of the parts, prolonging the service life and improving the stability of the chain during rotation are achieved, the manual chain is in friction contact with the friction plate during rotation, friction force is increased through the friction plate, and the friction force is reduced; the attachment to the surface of a component is improved, the rotating effect is improved, the surface is cleaned, stains on the surface of the chain are reduced, and slipping is prevented.

    本发明公开了一种具有限载功能的手拉葫芦,本发明涉及起重机械技术领域,包括葫芦机构。该具有限载功能的手拉葫芦,通过葫芦机构设计,通过拉动手动锁链控制复合机构对物料进行升降,手动锁链在摩擦机构表面转动,盖板连接硅胶块,对手动锁链进行覆盖遮挡,以此达到限制部件活动空间,避免发生扭转,影响手动升降效果,提高作业效率,硅胶块采用硅胶材质,硅胶具有一定的依附性和减震性,以此达到降低部件碰撞的作用,降低部件磨损,延长使用寿命,提高锁链转动时的稳定性,手动锁链转动时与摩擦板进行摩擦接触,通过摩擦板增加摩擦力,提高对部件表面依附性,提高转动效果,以及对表面起到清理作用,降低锁链表面污渍,防止发生滑落。
