Embodiment Construction

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0025] refer to Figure 1-3 , a buffer device for an elevator, comprising an elevator 7 and side walls 4 on both sides of the elevator. A reel 8 is arranged between the first fixed plates 10, and a flexible rope 6 is wound on the reel 8. The two ends of the reel 8 are affixed with a wire retaining reel 1, and the other side of the reel 1 is affixed with a rotating shaft. 9. The rotating shaft 9 is rotatably connected to the first fixing plate 10; through this device, the normal rotation of the reel 8 is ensured.

[0026] One of the wire retaining discs 1 is fixedly connected with an outer cylinder 33 inside, and the opening of the outer cylinder 33 faces outward, an...

Abstract

The invention relates to the technical field of elevator assisting devices, in particular to an elevator buffer device. The elevator buffer device comprises an elevator and lateral wall faces on two sides of the elevator and is characterized in that a buffer device body is arranged at the bottom of the elevator, the buffer device body comprises two parallelly-arranged first fixing plates which arefixedly connected to the bottom of the elevator, a winding reel is arranged between the two first fixing plates, a flexible rope winds the winding reel, rope baffles are fixedly connected to two endsof the winding reel, a slider is arranged inside a cylinder, a push rod is fixedly connected to one side, away from a rotary rod, of the slider, the other end of the push rod is arranged in a throughhole formed in the corresponding first fixing plate, the push rod is coaxial with a clamping rod, and the other end of the spring is fixedly connected to the inner wall of the cylinder. The elevatorbuffer device has the advantages that elevator buffer and clamping fixing are completed in a total mechanical manner, and high stability coefficient is achieved; due to the fact that the device startsclamping action when the elevator starts falling, the device can timely stop the elevator falling and well protect the safety of passengers.

Description

technical field [0001] The invention relates to the technical field of elevator auxiliary devices, in particular to an elevator buffer device. Background technique [0002] Elevator is a kind of vertical elevator powered by electric motor, also known as vertical elevator. The elevator is a fixed lifting device serving a specified floor, running between at least two vertical or rigid guide rails with an inclination angle of less than 15°. An elevator with a car whose size and structure are convenient for passengers to enter and exit or to load and unload goods. [0003] During the working process of the elevator, if the lifting device breaks down, it will cause the elevator to stop moving, or cause the elevator to fall, which will threaten the lives of passengers. [0004] Now people will install a buffer device at the bottom of the elevator shaft. When the elevator falls, the elevator falls on the buffer device for buffering to reduce the risk of falling. However, this kin...
