Problems solved by technology
[0002] With the development of social economy and the improvement of people's material level, there are more and more high-rise buildings, and the rated speed of the elevator is also getting higher and higher. Since the stroke of the buffer is proportional to the speed, it means that the higher the elevator speed, the higher the elevator speed. The larger the stroke of the required buffer, the higher the top space and bottom space of the elevator, which not only increases the cost of the buffer, but also greatly increases the construction difficulty and wastes the construction area

Embodiment Construction
[0024] An embodiment of a stroke-reducing one-way automatic anti-rolling vehicle speed limiting system, in Figure 1~9Among them, the base 1 of the speed limiter 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. Device, the base 1 is provided with a brake plate device on one side of the sheave 2, and the sheave 2 is wound with a steel 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 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 p...

The invention discloses a stroke-reducing one-way automatic anti-rolling car speed limiting system. An encoder is installed on the main shaft of the speed limiter, and a rope wheel is assembled on the main shaft. There is a pawl torsion spring between the pawl and the rope wheel to make the pawl turn to the ratchet and the ratchet slot, and a pawl positioning structure is installed on the wheel surface of the rope wheel, and the ratchet is far away from the gravity hammer. The disc is coaxially fixed on the wheel surface, and the outer edge of the disc is equipped with a self-resetting switch. Each self-resetting switch is located on a concentric circle of the disc. The free ends of the discs are respectively located on the circumference of a group of concentric circles of the disc, and the gravity hammer touches each self-resetting switch in turn during the opening process. The invention can realize the purpose of using higher-speed elevators in corresponding buildings without additionally increasing the top space and bottom space of the elevator, and without increasing the cost of the buffer.
Description
technical field [0001] The invention relates to a speed-limiting system for limiting the running speed of an elevator, in particular to a speed-reducing one-way automatic anti-rolling speed-limiting system. Background technique [0002] With the development of social economy and the improvement of people's material level, there are more and more high-rise buildings, and the rated speed of the elevator is also getting higher and higher. Since the stroke of the buffer is proportional to the speed, it means that the higher the elevator speed, the higher the elevator speed. The larger the stroke of the required buffer, the higher the top space and bottom space of the elevator, which not only increases the cost of the buffer, but also greatly increases the difficulty of construction and wastes the construction area. [0003] At present, the elevator speed is generally below 2.5m / s, and the elevator buffer is selected according to the rated speed of the elevator. [0004] The buf...
