Description
技术领域 technical field
本实用新型涉及电葫芦附件技术领域。 The utility model relates to the technical field of electric hoist accessories.
背景技术 Background technique
钢丝绳电动葫芦是一种小型起重设备，钢丝绳电动葫芦具有结构紧凑，重量轻，体积小，零部件通用性强，操作方便等优点，它既可以单独安装在工字钢上，也可以配套安装在电动或手动单梁、双梁、悬臂、龙门等起重机上使用，主要用于各种提升、牵移、装卸重物等。 The wire rope electric hoist is a small lifting equipment. The wire rope electric hoist has the advantages of compact structure, light weight, small volume, strong versatility of parts, and convenient operation. It can be installed on the I-beam alone or as a set Used on electric or manual single-girder, double-girder, cantilever, gantry and other cranes, mainly used for various lifting, pulling, loading and unloading heavy objects, etc.
钢丝绳电葫芦的操作规程之一是“禁止弯拉斜吊”，但在实际吊装过程中，因施工人员的素质或客观条件限制造成普遍存在弯拉斜吊现象。一旦出现这种情况，就很容易对电葫芦造成损害，轻则使其排线器、钢丝绳报废，重则使整个电动葫芦报废或人身伤害，从而造成一定的经济损失，严重影响施工生产。目前市场上销售的电葫芦上升限位器虽然花样繁多，但都是保证当吊钩起升到极限位置时自动切断起升电路的限位器，并不控制电葫芦的歪拉斜吊，为了避免操作过程中出现弯拉斜吊这一极大的安全隐患，急需一种更实用的限位装置。 One of the operating procedures for electric wire rope hoists is "prohibition of bending, pulling and slanting hanging", but in the actual hoisting process, the phenomenon of bending and pulling slanting hanging is common due to the quality of construction personnel or the limitation of objective conditions. Once this situation occurs, it is easy to cause damage to the electric hoist, ranging from scrapping the cable connector and wire rope, to scrapping the entire electric hoist or causing personal injury, thereby causing certain economic losses and seriously affecting construction and production. Although there are many kinds of electric hoist lift limiters currently on the market, they are all limiters that ensure that the lifting circuit is automatically cut off when the hook is lifted to the limit position, and do not control the crooked pulling of the electric hoist. To avoid the great potential safety hazard of bending, pulling and slanting hanging during operation, a more practical limiting device is urgently needed.
