Description

Car Vibration Damping Structure of Heavy Freight High Speed Elevator

technical field

The invention relates to the technical field of elevators, in particular to a vibration damping structure of a car.

Background technique

For elevators, whether they are passenger elevators or freight elevators, in addition to meeting the safety requirements, the running quality is also essential for every elevator. Passengers will evaluate the quality of an elevator by the running quality of the elevator during operation. Therefore, Doing good vibration reduction measures is an important technical means to improve the quality of elevator operation.

Contents of the invention

The technical problem to be solved by the present invention is to provide a car vibration damping structure that improves the comfort of taking an elevator.

The technical solution adopted in order to solve the above technical problems: a car vibration damping structure of a heavy-duty high-speed elevator, including a car and a car frame for hoisting the car, the car includes a car top and a car bottom, and the car bottom includes There are an upper car floor and a lower car floor, and screw fastening is used between the horizontal frames of the upper car floor and the lower car floor. It is cushioned with vibration damping rubber, and the two sides of the vibration damping rubber are clamped with splints. The two sides of the car top are respectively clamped by a concave piece to the column of the car frame. The concave piece includes a bottom plate fixed on the car top and a bottom plate fixed on the bottom The upper side member and the middle member, the side member is provided with two pieces, which are respectively placed at the two ends of the middle member, and the sides of the side member and the middle member facing the column are fixed with vibration-damping glue.

Beneficial effects brought by the adoption of the present invention: the present invention provides damping rubber on the spacer pad between the upper car bottom and the lower car bottom of the car, which can improve the load buffering effect of the car; the concave part clamps the contact surface of the column It is fixed with damping rubber, which can reduce and change the vibration from the car frame, making the elevator run more smoothly and comfortably.

Detailed ways

As shown in Figure 1-3, a car vibration damping structure of a heavy-duty high-speed elevator includes a car 1 and a car frame 2 for hoisting the car 1. The car 1 includes a car top and a car bottom, and the car bottom The upper car bottom 3 and the lower car bottom 4 are included, and the horizontal frames 5 of the upper car bottom 3 and the lower car bottom 4 are fastened with threads. In the present invention, the spacer at the thread fastening place between the upper car bottom 3 and the horizontal frame 5 of the lower car bottom 4 is provided with damping rubber 6, and splints 7 are clamped on both sides of the vibration damping rubber 6, and the car top The two sides of the car frame 2 are respectively clamped by a concave piece to the column 8 of the car frame 2. The concave piece includes a bottom plate 9 fixed on the car top and a side member 10 and a middle member 11 fixed on the bottom 9. The side member 10 is provided with The two pieces are respectively placed at the two ends of the middle member 11 , and the sides of the side member 10 and the middle member 11 facing the column 8 are fixed with damping glue 12 .

The lower car bottom 4 is fixed on the bottom beam 13 of the car frame 2, and the upper car bottom 3 together with the entire car is fixed on the lower car bottom 4 through the damping rubber 6. The vibration damping rubber 6 not only plays the role of load buffering, but also can reduce the load. The vibration of the car from the car frame 2. The concave parts on the top of the car used to clamp the uprights 8 of the car frame are also in contact with the uprights 8 through the damping rubber 12, which can further reduce the vibration from the car frame 2, make the elevator run more stable and comfortable, and greatly improve the comfort of taking the elevator. comfort.
