Embodiment Construction

[0015] An embodiment of a two-way machine-room-less automatic anti-rolling speed limiter, in Figure 1~5Among them, the so-called two-way speed limiter is a speed limiter that can function when the elevator goes up and down. The base 1 is equipped with a rope wheel 2 and a ratchet 3 through the rotation of the main shaft. The two ends of the main shaft are arranged on the base 1 through bearings. The rope wheel 2 and the ratchet wheel 3 are non-rotatably assembled on the main shaft, and an encoder (not shown in the figure, which is installed in the same way as the prior art) is installed on one end of the main shaft, and the rope wheel 2 is wound with a wire rope. The diameter of the ratchet 3 is smaller than the diameter of the sheave 2, and a ratchet 4 is installed on the wheel surface of the sheave 2. A torsion spring is arranged between the pawl 4 and the sheave 2, and the torsion spring gives the torsion force to the pawl 4, so that the ratchet The rotation of the pawl 4 ...

Abstract

The invention discloses a bidirectional overspeed governor provided with an automatic anti-slip function and used on an elevator without a machine room. The main shaft of the overspeed governor is rotationally arranged on a base; a rope sheave and a ratchet wheel are mounted on the main shaft in a splined manner; an encoder is mounted on the main shaft; a pawl is rotationally mounted on one side of one surface of the rope sheave; a pawl torsional spring is arranged between the pawl and the rope sheave, and can enable the pawl to turn to the ratchet wheel and be clamped in the clamping groove of the ratchet wheel; a pawl positioning structure is rotationally mounted on the surface of the rope sheave; the jacking end of the pawl positioning structure is in elastic and jacking fit with the pawl; two gravity hammers are rotationally mounted on another side of the surface of the rope sheave; a raised jacking head is arranged at the trigger part of the pawl positioning structure and can coordinate with the power hammers (i.e. the gravity hammers) in a pushing and pressing manner when the hammerheads of the gravity hammers are turned to the outer edge of the rope sheave; a raised lifting release link is arranged on the pawl; the encoder is in transmission connection with a master elevator control system; the master elevator control system is in control connection with an electromagnet. According to the invention, the pawl and the pawl positioning structure do not need manual reset, and the bidirectional overspeed governor can be used in an elevator without machine room.

Description

technical field [0001] The invention relates to a speed governor for limiting the running speed of an elevator, in particular to a two-way machine room-less automatic anti-rolling speed governor. Background technique [0002] The overspeed governor is a key part of elevator safety. There is a kind of such two-way overspeed governor in the prior art. A rope wheel and a ratchet are installed through the rotation of the main shaft. The two ends of the main shaft are arranged on the base through bearings. The diameter of the ratchet wheel is smaller than the diameter of the rope wheel. A ratchet is installed on the wheel surface of the rope wheel. A torsion spring is arranged between the ratchet and the sheave. The trend of card slot matching, when the pawl is in a free state, the pawl and the ratchet will be in a clamped state, and a block is protruded from the end of the pawl, and the two sides of the block can be inserted into the two sides of the slot. There are two groove...
