The invention provides an anti-falling device, and belongs to the technical field of self-locking equipment. The anti-falling device comprises an anti-falling mechanism arranged on a workbench, the anti-falling mechanism comprises a clamping strip which is arranged on the lower side of the lifting belt and provided with a clamping opening and a self-locking mechanism rotationally connected to the workbench, the self-locking mechanism comprises a clamping part matched with the clamping opening and a baffle, and an included angle is formed between the clamping part and the baffle. A check block used for preventing the workbench from falling off is arranged on the side, facing the baffle, of the rack. In the normal operation state, the upper side of the clamping strip is fixed to the lower side of the lifting belt, and the clamping part is clamped to the inner side of the clamping opening. When an accident occurs, for example, the lifting belt is broken, the clamping strip arranged on the lower side of the lifting belt is released. Under the action of gravity, the clamping part is separated from the clamping opening, then the baffle rotates and is clamped to the stop block, the effect of preventing the workbench from falling is achieved, and the problems that an elevator belt is started and stopped frequently, the speed change amplitude is large, and the mechanical loss of equipment is large are effectively solved.

    本发明提供了一种防脱落装置,属于自锁设备技术领域。它包括设于工作台上的防脱落机构,防脱落机构包括设在提升带下侧的带有卡接口的卡条,旋接在工作台上的自锁机构,自锁机构包括具有与该卡接口相适配的卡接部,与卡接部呈夹角设置的挡板,机架上朝向挡板的一侧设置用于防止工作台发生脱落的挡块。在本发明正常运行状态下,卡条上侧固定在提升带的下侧,卡接部卡设在卡接口的内侧。发生意外现象时,如提升带发生断裂的情况,设置在提升带下侧的卡条被释放。在重力的作用下,卡接部从卡接口中脱离出来,接着挡板发生旋转并卡到挡块上,起到防止工作台坠落的作用,有效解决了提升带频繁启停、速度变化幅度大、设备机械损耗大等问题。
