Description

Villa elevator buffer

Technical Field

The utility model belongs to the elevator field, more specifically the utility model relates to a villa elevator buffer that says so.

Background

An elevator is a permanent transport device serving a number of specific floors in a building, the car of which travels in at least two rigid orbital movements perpendicular to the horizontal or inclined at an angle of less than 15 ° to the vertical, a fixed lifting device serving the given floor.

Under some extreme circumstances, the car body can take place the dangerous situation of falling rapidly, treats that the car body falls the well bottom rapidly, because the car bottom lacks the damper who can realize the buffering effect, the personnel that are located the car can receive the injury of different degrees because huge impact force can, and the falling force that produces can not obtain timely dispersion, can lead to dying when serious.

SUMMERY OF THE UTILITY MODEL

To the not enough of prior art, the utility model provides a can play the villa elevator buffer of cushioning effect when dropping the car.

In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a villa elevator buffer, includes the bottom plate, the side fixing has fixed frame on the bottom plate, be fixed with a plurality of dead levers around bottom plate central line circumference evenly distributed on the outer wall of fixed frame, be equipped with the spout that communicates with the inner wall of fixed frame in the dead lever, it has the slide bar to peg graft in the spout, be equipped with first buffer spring between the one end that slide bar and spout were pegged graft and the bottom surface of spout, the other end of slide bar articulates there is the buffer beam, the top of bottom plate is equipped with first buffer board, every the one end that the slide bar was kept away from to the buffer beam all articulates with first buffer board.

By adopting the technical scheme, when the lift car falls onto the first buffer plate to apply pressure to the first buffer plate, the first buffer plate moves downwards under the pressure, the buffer rod drives the sliding rod to move towards the sliding groove, and the first buffer spring is compressed by the acting force of the sliding rod, so that the buffering effect can be achieved; because first buffer spring sets up in the spout to avoid outside material to drop inside first buffer spring and lead to first buffer spring's inefficacy.

Further, the side of going up of bottom plate still is fixed with the fixed column, the side of going up of fixed column is equipped with the ascending mounting groove of opening, it has the bracing piece to peg graft in the mounting groove, the bracing piece extends into and is equipped with second buffer spring between the one end of mounting groove and the bottom surface of mounting groove, the bracing piece is kept away from the one end of second buffer spring and is extended the buffer board.

Through adopting above-mentioned technical scheme, contact the bracing piece earlier when the car drops, bracing piece atress moves down and extrudees second buffer spring, cushions the pressure of a part car earlier, and the car continues to move down and contacts first buffer board, and the car drives first buffer board downstream, and first buffer spring and second buffer spring play the cushioning effect to the car jointly this moment, and the effect of buffering is better.

Furthermore, a second buffer plate is fixed at one end of the support rod extending out of the buffer plate.

Through adopting above-mentioned technical scheme, the area of contact of bracing piece and car can be increased to the second buffer board, more steady when making the car drop.

Furthermore, a plurality of reinforcing ribs are arranged between the fixing column and the bottom plate, and the reinforcing ribs are uniformly distributed around the circumference of the axis of the fixing column.

Through adopting above-mentioned technical scheme, the strengthening rib can increase the joint strength between fixed column and the bottom plate.

Further, the side of going up of slide bar is equipped with the constant head tank that extends along slide bar length, the bottom surface of constant head tank is equipped with a plurality of location steps of arranging in proper order along constant head tank length direction, the height of location step increases in proper order to fixed frame outside direction from fixed frame center, wear to be equipped with the locating lever that one end extended into the constant head tank on the dead lever.

Through adopting above-mentioned technical scheme, drive the slide bar and remove in the spout when first buffer board pressurized downstream, the locating lever removes highly lower location step owing to receive its lower extreme of gravity reason this moment, when the car drops to the minimum, the lower extreme of locating lever removes highly minimum location step this moment on, the slide bar receives first buffer spring's resilience force and removes outside the spout after that, the distance that the slide bar outwards removed can be restricted to minimum location step, thereby avoid the car because the resilience force of first buffer spring upwards bounces the car and causes the personnel discomfort in the car.

Furthermore, a first elastic layer is arranged above the first buffer plate.

Furthermore, a second elastic layer is arranged at the upper end of the fixing column.

To sum up, the utility model has the advantages that: 1. when the lift car drops, the lift car contacts with the second buffer plate firstly, the second buffer plate is stressed to move downwards, the second buffer spring is extruded through the support rod, the second buffer spring plays a buffering role firstly, the lift car continues to move downwards until the second buffer plate contacts with the first buffer plate, the lift car drives the second buffer plate and the first buffer plate to move downwards, the second buffer plate drives the slide rod to move towards the sliding chute through the buffer rod, the first buffer spring is compressed by the acting force of the slide rod, at the moment, the first buffer spring and the second buffer spring play a buffering role on the lift car together, and the buffering effect is good; 2. first buffer spring sets up in the spout to avoid outside material to drop inside first buffer spring and lead to first buffer spring's inefficacy.
