Description

A lifting type elevator falling deceleration buffer braking system

technical field

The utility model relates to a deceleration system for lifting equipment falling, in particular to a falling deceleration, buffering and braking system for lift elevators.

Background technique

With the concentration of population in cities, the acceleration of urbanization, and the rapid development of the construction industry, many high-rise buildings have appeared, whether they are commercial buildings or residential buildings, the use of elevators has become particularly widespread, but the use of elevators will or There are more or less safety problems, and once the elevator fails, it will bring a serious threat to the life safety of the people in the elevator.

For example, the patent No. 201210432242.9 is an invention, a kind of safety elevator, which is designed with several rows of horizontal bars on the top of the elevator. When the elevator breaks down, it can save people's lives. If the elevator breaks down and descends rapidly, people in the elevator can grab the horizontal bar and make their feet leave the elevator floor gently. The rapidly descending elevator will produce a great impact when it is close to the ground. The impact damaged the legs, and even the chest cavity, destroying the internal organs and endangering life. Because of the buffer of the horizontal bar, part of the impact force is relieved when the elevator hits the ground. Can greatly reduce people's injuries. The invention has the advantages of simple structure, convenient use and popularization, and the buffering resistance of the horizontal bar in the method is limited, and cannot bear the huge impact force of the elevator falling when it is carrying people.

For example, the utility model patent No. 201120113516.9 discloses an elevator car, which includes components such as a car frame, an inner car floor, and an outer car floor. A buffer body, the upper end of the buoyancy buffer body is connected to the inner car bottom. The utility model adopts the liquid buoyancy to buffer the vibration at the bottom of the elevator, which not only effectively overcomes the defect that the rubber pad of the car is easily deformed, but also can reduce the noise of the car by using the sound insulation characteristics of the liquid, so as to create a comfortable environment for the passengers. , this method uses the plasticity of water to realize the cushioning of the people in the elevator car, but this method is more suitable for elevators with few people, otherwise, if the people in the elevator are evenly distributed, the effect of the method cannot be reflected.

Utility model content

The technical problem to be solved by the utility model is to provide a deceleration buffer braking system for the falling of the lift elevator in view of the above-mentioned deficiencies in the prior art.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:

A lifting type elevator falling deceleration buffer brake system, comprising an elevator car body, an upper buffer mechanism is arranged at the bottom of the elevator car body, and the upper buffer mechanism includes a sliding inclined block, and there is a gap between the sliding inclined block and the elevator car body. The sliding seat is fixed, and the sliding inclined block is slidably arranged in the fixed sliding seat. The lower surface of the sliding inclined block is an inclined plane, and there is a baffle at the bottom edge of the elevator car body. A spring is arranged between them, and a lower brake mechanism is provided below the upper buffer mechanism. The lower brake mechanism is divided into a load-bearing part and a brake base. Connection, the load-bearing part has a slope that cooperates with the sliding inclined block, and the bottom of the connection load-bearing part is provided with a pressure transmission rod. The pressure transmission rod is set through the brake base and is located on the brake base near the side wall of the elevator shaft. There are brake pads, and there is a fixed spring between the brake pads and the brake base, and there is a movable linkage link between the brake pads and the pressure transmission rod part outside the lower part of the brake base, and the pressure transmission The expansion and contraction of the rod in the brake base is used to drive the linkage rod to prop up the brake pads to the side wall of the elevator shaft.

As a further preferred solution, the angle of the slope generated by the sliding ramp is 15°-45° relative to the horizontal direction.

As a further preferred solution, the length of the sliding ramp in the sliding direction is smaller than the length of the bearing part.

As a further preferred solution, the width of the load-bearing part is smaller than the width of the sliding ramp, and the highest part of the load-bearing part has a plane step.

As a further preferred solution, the sliding end of the sliding ramp on the bearing part is provided with a crushing protrusion that produces resistance.

Compared with the prior art, the elevator falling deceleration and buffer braking system of the utility model, on the one hand, can offset the impact of part of the falling by sliding the inclined sliding block at the bottom of the elevator car body and the load-bearing part obliquely to each other. On the other hand, the pressure transmission rod is pressed down by the load-bearing part, and the linkage rod is lifted horizontally, so that the brake pads are continuously attached to the side wall of the elevator, resulting in frictional braking, and the cracks on the load-bearing part The protrusion also slows down the sliding of the sliding block to a certain extent, increases the resistance, and improves the cushioning performance. The utility model has a novel structure, which can greatly improve the safety of the lift elevator when it falls down, and avoid large-scale and large-scale damage. casualties.
