Description
Technical Field
The invention relates to the field of elevator equipment, in particular to a safety tongs and rope clamp linkage mechanism for an elevator and a using method thereof.
Background
An elevator is a permanent transport device serving a number of specific floors in a building, the cars of which travel in at least two rigid tracks perpendicular to the horizontal or inclined at an angle of less than 15 ° to the vertical. There are also steps, where the tread plates are mounted on a track for continuous operation, commonly known as escalators or moving walkways. A fixed elevator apparatus serving a predetermined floor. The vertical lift elevator has a car that runs between at least two vertical rows of rigid guide rails or guide rails with an angle of inclination of less than 15 °. The size and the structural form of the car are convenient for passengers to access or load and unload goods. It is customary to use elevators as a generic term for vertical transport means in buildings, irrespective of their drive mode. According to the speed, the elevator can be divided into a low-speed elevator (below 4 m/s), a high-speed elevator (4-12 m/s) and a high-speed elevator (above 12 m/s). The hydraulic elevator begins to appear in the middle of the 19 th century and is still applied to low-rise buildings until now. In 1852, e.g. austs in the united states developed a safety hoist for wire rope hoisting. In the 80 s, further improvements were made to the drive means, such as motors driving the winding drum via a worm drive, the use of counterweights, etc. At the end of the 19 th century, friction wheel transmission is adopted, and the lifting height of the elevator is greatly increased.
The industrial data shows that the increase rate of the number of the whole elevator production in China exceeds 10% in the first half of 2014, the shipment quantity in the next half is reduced in proportion to the order, the production and sales quantity increase in the whole year is kept about 10%, and the increase rate is reduced compared with the increase rate in the last year. However, the total output of the whole elevator in the whole year breaks through 70 thousands of elevators and has been settled, and the holding capacity of the elevators in the whole country can reach more than 350 thousands of elevators. China has become the largest elevator production and consumption market in the world, and major elevator brand enterprises in the world all establish independent or joint-fund enterprises in China, and are world factories and manufacturing centers in the elevator field. 70% of elevators worldwide are manufactured in china and 60% to 65% of elevators are sold in the chinese market.
However, the elevator systems used in the market today have the following disadvantages: the existing elevator is mainly used for controlling the speed and the safety of the elevator through a speed limiter, and the speed limiter is a mechanical structure and is easy to accelerate and age after frequent use, so that faults are caused and unnecessary potential safety hazards are caused. The safety tongs and the rope clamping device cannot be triggered simultaneously when an accident happens to the existing elevator, and the optimal braking effect cannot be achieved. The material that current rope clamp used can cause great impact to the towline for the damage of equipment to the maintenance and the maintenance of rope clamp are comparatively loaded down with trivial details. The existing rope clamp cannot be automatically recovered after being triggered in an emergency state, and the use is manually recovered, so that the existing rope clamp is troublesome. Current buffer for elevator is mostly solitary spring structure or hydraulic buffer, and the buffering dynamics of these both springs when using is not enough to buffer and car direct contact, it is great to the impact of car, endangers personnel's safety in the elevator, and the elevator has unnecessary debris to fall into the elevator bottom from the gap of elevator operation when using simultaneously, and then influences the buffering effect of buffer.
