Fall buffering speed reducer of lifting equipment

Abstract

The invention discloses a fall buffering speed reducer of lifting equipment. The fall buffering speed reducer of the lifting equipment comprises a lifting equipment body; an air inflation cylinder and spray gun devices are disposed at the bottoms of the lifting equipment body; each spray gun device comprises a spray gun pipe, a bullet storing chamber is disposed under the corresponding spray gun pipe, air nail bullets are loaded in the corresponding bullet storing chamber, the multiple air nail bullets are connected through pulling ropes, and one end of each pulling rope is fixed to the bottom of the corresponding bullet storing chamber; the lifting equipment body is further provided with a switch, and a buffering mechanism is arranged by being close to the bullet storing chambers. Compared with the prior art, the fall buffering speed reducer of the lifting equipment is nailed to the wall of an elevator shaft by continuously shooting the air nail bullets, finally the lifting equipment is dragged through the pulling ropes connected to the air nail bullets, therefore each air nail bullet bears stress to complete pulling of the lifting equipment together, the function of preventing the lifting equipment from falling caused by faults is achieved, and life and property loss is reduced.

Description

technical field [0001] The invention relates to a fall prevention device, which belongs to the safety field of automation equipment, in particular to a fall buffering and deceleration device for a lifting device. Background technique [0002] With the increase of high-rise buildings, the use of elevators is also increasing, and with the increase of elevator use, the frequency of elevator falling accidents is getting higher and higher. The quality of the existing elevator itself is not a problem. Whether the elevator can operate normally, A lot depends on the installation technique. Some elevator companies hire non-professional installers. They do not handle the elevator shaft and tracks carefully during the elevator installation process, which makes the balance of the elevator running poor, and even causes problems such as vibration and noise that are difficult to repair. These problems are It is solved by the installers. If the installation is not careful enough, the insta...

Problems solved by technology

Man-operated wooden wedges are used to brake the elevator. Even if the elevator can be decelerated to a certain extent, if the passengers are elderly or children, they will not have enough strength to complete the deceleration operation. Therefore, the low degree of automation is its disadvantage.
