Abstract

The invention relates to the technical field of elevator safety tongs, and discloses a stable elevator safety tongs capable of reducing equipment loss, which comprises a guide rail, the outer side of the guide rail is sleeved with a safety tongs mechanism, the safety tongs mechanism comprises an initial tong, and the bottom of the initial tong is riveted with a variable tong; a fixed wedge block and a movable wedge block are slidably connected to the interior of the initial clamp, a connecting rod is hinged to the outer side of the movable wedge block, a hinge block is slidably connected to the interior of the connecting rod, and a control mechanism is installed on the outer side of the safety clamp mechanism. According to the stable elevator safety tongs capable of reducing the equipment loss, by changing the triggering condition of the ejector block, when the braking distance needs to be prolonged, the elastic force applied to the ejector block by the buffer spring is increased, the number of the movable wedge blocks rising synchronously is reduced at the same speed of an elevator, otherwise, the number of the movable wedge blocks is increased, and therefore the stable elevator safety tongs can be suitable for braking in different environments; and the use is convenient.

Description

technical field [0001] The invention relates to the technical field of elevator safety gear, in particular to a stable elevator safety gear that can reduce equipment loss. Background technique [0002] Elevator is a kind of transportation equipment for transporting pedestrians or goods vertically. Elevator safety gear is a device that can clamp the guide rail and brake the elevator at the same time when the elevator suddenly happens, and firmly clamp the elevator on the guide rail. , the safety gear is usually used in conjunction with the speed limiter. When the elevator runs at overspeed, the speed limiter starts to pull up the pull rod of the safety gear, so that the safety gear clamps the guide rail to brake the elevator car. The traditional safety gear is divided into instantaneous formula and progressive. [0003] When the elevator safety gear is braking, in order to increase the braking range, multiple sets of safety gears are usually used for multi-stage braking. Th...
