Problems solved by technology

[0002] An elevator is a hoisting machine that transports people or objects vertically. It also refers to the equipment for vertical transportation in logistics systems such as factories and automatic warehouses. The elevator platform is often equipped with various plane conveying equipment, which serves as the conveyor line of different heights. The connection device is generally driven by hydraulic pressure, so it is called a hydraulic lifting platform. In addition to being used for the transportation of goods at different heights, it is widely used in high-altitude installation, maintenance and other operations. When the elevator suddenly breaks down, it is very easy to fall, which will threaten To the safety of the staff, the machine will also be seriously damaged

Abstract

The invention discloses an anti-falling device for an elevator. The anti-falling device for the elevator comprises a base, a first anti-falling mechanism, a cover frame, a second anti-falling mechanism and winding drums; a first belt wheel is connected to a second belt wheel through a transmission belt; a transmission shaft penetrates through the second anti-falling mechanism; the winding drums are connected to the front end and the rear end of the transmission shaft; a lifting rope is wound around the outer side of each winding drum; the lifting ropes bypass fixed pulleys to be connected withtension sensors; the tension sensors are fixed to the left side and the right side of the upper end face of a bearing plate through fasteners; and the tension sensors are located on the outer sides of the limiting plates. According to the anti-falling device for the elevator, after the lifting ropes lift the bearing plate, the tension sensors start to work; when the lifting rope is accidentally broken, the tension value detected by the corresponding tension sensor is zero; and at the moment, a movable block moves under the extension effect of a first piston rod, and a second clamping block moves along with the movable block and are connected to a first clamping block in a clamped mode, so that the bearing plate can be conveniently fixed in time, and the inclining or falling of the bearingplate can be avoided.
