Embodiment Construction

[0014] An embodiment of a one-way machine-roomless speed limiter, in Figure 1~5 Among them, a sheave 2 and a ratchet 3 are installed coaxially rotating on the base 1, and a wire rope is wound on the sheave 2. 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 always has a tendency to engage with the slot of the ratchet 3. When the pawl 4 is in a free state, the pawl 4 and the ratchet 3 will be in a clamped state, and a pawl is also rotated on the rope wheel 2. The positioning structure 6, the pawl positioning structure 6 has a pressing end, and the pressing end presses on the pawl 4, so that the pawl 4 is in the normal state of releasing the ratchet 3, the connection between the pawl positioning structure 6 and th...

Abstract

The invention discloses a one-way speed limiter without a machine room. According to the invention, a base is coaxially and rotationally equipped with a rope wheel and a ratchet wheel; one side of the wheel face of the rope wheel is rotationally equipped with pawls; pawl torsional springs allowing the pawls to turn to the ratchet wheel to be matched with clamping grooves in the ratchet wheel in a clamping manner are arranged between the pawls and the rope wheel; the wheel face of the rope wheel is also rotationally equipped with pawl positioning structures; positioning torsional springs are arranged between the pawl positioning structures and the rope wheel; the supporting and pressing ends of the pawl positioning structures are matched with the pawls in an elastic supporting and pressing manner; the other side of the rope wheel face is rotationally equipped with two gravity hammers; the trigger parts of the pawl positioning structures are convexly provided with ejector headers matched with power hammers in a push-press manner when hammer heads of the gravity hammers turn to the outer edge of the rope wheel; the pawls are convexly provided with lifting release links, and when hammer handles of the gravity hammers turn to the wheel edge of the rope wheel, the lifting release links support and press the hammer handles of the gravity hammers to allow the pawls to be separated from the ratchet wheel and the pawl positioning structures and the pawls to be reset. According to the one-way speed limiter without the machine room, manual reset is not required for the pawl and the pawl positioning structures, and the one-way speed limiter without the machine room can be used in an elevator without the 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 one-way machine-roomless speed governor. Background technique [0002] Speed ​​governor is the key part of elevator safety, and there is a kind of such speed governor in the prior art, comprises base, and coaxial rotation is equipped with sheave and ratchet on the base, and is wound with wire rope on the sheave. 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 engagement, when the pawl is in a free state, the pawl and the ratchet will be in a clamped state, and a pawl positioning structure is also rotated on the rope wheel, and the pawl positioning structure has a top pressure end. The pressing end presses against the ratchet, so that the ratchet is in the norm...
