In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a screw elevator's bradyseism device, its mainly used adopts on the elevator that the screw rod goes up and down, includes the base, at least one damper who locates on the base, damper includes the base, rotationally locates the adjustable shelf on the base, rotationally locates the buffering wheel of adjustable shelf, locates the elastic mechanism between base and the adjustable shelf.

Further:

the base with be equipped with the aperture on the adjustable shelf respectively, elastic mechanism locates buffer spring on the bolt including wearing to locate two apertures, cover, the diameter of bolt is less than the diameter of at least one aperture, buffer spring one end is supported and is leaned on in the base, the buffer spring other end supports and leans on in the bolt tip, the bolt other end is equipped with the nut, the nut supports and leans on in the adjustable shelf.

The middle part of the movable frame is rotatably connected to the base through a rotating shaft, the elastic mechanism is arranged at the bottom of the movable frame, and the buffer wheel is arranged at the top of the movable frame.

The base middle part is equipped with a through-hole, and the through-hole is worn to locate by the screw rod, damper's quantity is three, and three damper's the horizontal connecting line of buffering wheel forms equilateral triangle, the buffering wheel supports and leans on in the screw rod.

By adopting the technical scheme, the beneficial effects of the utility model are that:

when the elevator runs, the base is fixed on the elevator box body, the base goes up and down along with the elevator box body, the buffer wheel is abutted against the screw rod, rolling friction is generated between the buffer wheel and the screw rod, when the elevator vibrates, pressure is generated between the buffer wheel and the screw rod, the buffer wheel moves due to the vibration of the screw rod, the buffer wheel generates tiny movement along with the movable frame, the elastic mechanism pulls the movable frame back to the original position, a certain cushioning effect is achieved, the vibration between the elevator box body and the screw rod is small, and the generated noise is small; further, damper's quantity is three, and three buffering wheel connecting wire is equilateral triangle, and the buffering of triangle-shaped structure is effectual for the elevator operation is more stable, and the noise is few.

Detailed Description

The present invention will now be further described with reference to the accompanying drawings and detailed description.

Referring to fig. 1 to 4, this embodiment provides a screw elevator's bradyseism device, its mainly used adopts on the elevator that the screw rod goes up and down, including base 1, three damper 2 of locating on base 1, base 1 middle part is equipped with a through-hole 10, the screw rod is worn to locate through-hole 10, the horizontal connecting wire of three damper 2's buffering wheel 23 forms an equilateral triangle, damper 2 includes base 21, the adjustable shelf 22 on base 21 is rotationally located, rotationally locate adjustable shelf 22's buffering wheel 23, locate the elastic mechanism between base 21 and the adjustable shelf 22, rotatable coupling is passed through pivot 25 in base 21 in the middle part of adjustable shelf 22, the elastic mechanism locates the adjustable shelf 22 bottom, the adjustable shelf 22 top is located to buffering wheel 23, buffering wheel 23 supports and leans on in the screw rod. The base 21 and the movable frame 22 are respectively provided with small holes 20, the elastic mechanism comprises a bolt 241 penetrating through the two small holes 20 and a buffer spring 242 sleeved on the bolt 241, the diameter of the bolt 241 is smaller than the diameters of the two small holes 20, one end of the buffer spring 242 abuts against the base 21, the other end of the buffer spring 242 abuts against the end of the bolt 241, the other end of the bolt 241 is provided with a nut 243, and the nut 243 abuts against the movable frame 22.

The elastic mechanism may also be a pneumatic rod or other components with elastic function, which are well known and will not be described herein.
