Problems solved by technology

[0005] In order to overcome that when the anti-fall safety device does not reach the rated speed, the centrifugal block is also subjected to the action of centrifugal force to stretch the extension spring. After a long time, the extension spring will fail or the tension will weaken, so that the centrifugal block will easily trigger the braking effect. The technical problem to be solved is: to provide a kind of anti-drop safety device with automatic grease injection function for elevators

Abstract

The invention relates to the technical field of anti-falling safety devices for elevators, in particular to an anti-falling safety device with an automatic grease injection function for an elevator. The technical problem to be solved is that a tension spring connected with a centrifugal block fails or tension is weakened after a long time, so that the centrifugal block is easy to trigger a braking effect. According to the technical scheme, the anti-falling safety device with the automatic grease injection function for the elevator comprises an outer cone, an automatic grease injection mechanism and a centrifugal mechanism, the automatic grease injection mechanism is arranged on the front portion of the outer cone, and the centrifugal mechanism is located in the middle of the outer cone. By arranging the centrifugal mechanism, the situation that when the device works normally, a centrifugal block is thrown out to make contact with a second fixing block, an elevator is braked when descending, and normal use of the elevator is affected is avoided; the situation that an operator does not inject grease into the sealed bearing in time, and consequently a bearing bush in the sealed bearing is abraded is avoided.

Description

technical field [0001] The invention relates to the technical field of elevator anti-falling safety devices, in particular to an anti-falling safety device with automatic grease injection function for elevators. Background technique [0002] Nowadays, the transportation of materials and the up and down movement of people in building construction are basically in the form of elevators. The traditional elevators use anti-fall safety devices, which greatly improves the safety factor, so that elevators are widely used in buildings. The driven car is running. When there is a sudden fall when descending, the centrifugal block inside the anti-fall safety device is thrown back around and clamped to the inner vertebral body to drive it to rotate together when the rotation speed is too fast. Brake by friction with the outer cone. [0003] The centrifugal block in the existing anti-fall safety device is pulled by the tension spring. During the normal descent of the elevator, the centr...
