Embodiment
The technical scheme of this patent is described in more detail with reference to embodiment.
Referring to Fig. 1, a kind of Buffer for elevator, including seat 1 is hit, the lower end for hitting seat 1 is arranged on the top of impact bar 2
End, the lower end of impact bar 2 are provided with piston 8, and piston 8 is slidably installed inside cylinder shell 4, and the top of cylinder shell 4 is with hitting
Back-moving spring 3 is also equipped with outside impact bar 2 between seat 1；The lower ending opening of the cylinder shell 4, and opening cooperation is provided with
End cap 5, the centre of end cap 5 are provided with adjustment mechanism 6, and adjustment mechanism 6 includes the vertical center of end cap 5 that is threaded in
Adjustment column 11, the upper end of adjustment column 11 are in the top of end cap 5 and are provided with adjustment pallet 12, and the lower end of adjustment column 11 is provided with handle
13, buffer spring 7 is provided between the adjustment pallet 12 and piston 8, the upper end of buffer spring 7 props up plug 8, and lower end props up adjustment
Pallet 12；The upper end of the cylinder shell 4 offers vertical direction perforate 9, and wear-resistant sleeve 10 is provided with vertical direction perforate 9, resistance to
Grinding set 10 can effectively reduce the friction of impact bar 2 and cylinder shell 4, improve service life.
In order to avoid handle 13 interferes with outside, adjustment column 11 is generally set to stretch into the mounting hole 14 of end cap 5, simultaneously
The most lower edge of handle 13 is set not protrude from the lower surface of end cap 5, so, handle 13 would not interfere with outside other structures part
.
The bottom of wear-resistant sleeve 10 is in same level with the top inner wall of cylinder shell 4, and so, the length of wear-resistant sleeve 10 exists
Structure has reached maximum in the range of allowing, and plays the effect of guide pin bushing to greatest extent, while the lower edge of wear-resistant sleeve 10 is not dashed forward
For the top lower edge of cylinder shell 4, also avoid piston 8 and strike wear-resistant sleeve 10.
Because wear-resistant sleeve 10 there may be size or the error of fit on, make the bottom surface of wear-resistant sleeve 10 is low to cross the top of cylinder shell 4
Inner wall lower edge, now the can of piston 8 directly impinge wear-resistant sleeve 10, wear-resistant sleeve 10 is damaged or is come off because of shock.So
Generally rubber blanket 15 is set in the inner wall lower edge at the top of the cylinder shell 4, impact of the damper piston 8 to the top of cylinder shell 4, and
Completely isolated piston 8 and wear-resistant sleeve 10, avoid colliding.
The adjustment pallet 12 is coaxially disposed with cylinder shell 4, and there are the heavy platform 17 for the buffer spring 7 that is loaded, buffering elastic in its middle part
Firm being fixed on of spring 7 adjusts the upper end of pallet 12, by screwing handle 13, adjustment column 11 is moved up or is moved down, and then make adjustment
Pallet 12 is moved up or moved down, and reaches the purpose for changing piston 8 and adjusting the reduction length of buffer spring 7 between pallet 12, is realized overall
Different degrees of cushion effect.
The lower end of piston 8 is provided with concave station 18, and the upper end of buffer spring 7 is sunk in concave station 18, fixes buffer spring 7 steady
Reinforce and lean on, be not easy to slip.
The side of the cylinder shell 4 is provided with damping hole 16, and the aperture of damping hole 16 gradually expands from the outside to the core, may be such that resistance
The air of the inner side of Buddhist nun hole 16 is easily drained, and the cavity in outside enters cylinder shell 4 more slowly, so as to reach slowly release buffering
The purpose of spring and back-moving spring 3.
In order to ensure the sealing property of cylinder shell 4, piston 8 is provided with sealing ring 20, and piston 8 passes through sealing ring 20 and cylinder
4 inwalls are in close contact, and the sealing ring 20 is provided with two.
For further cushion impact forces, the upper surface for hitting seat 1 is also equipped with buffer stopper 19, and buffer stopper 19 is poly- ammonia
Ester, the shaft section of buffer stopper 19 is spherical crown surface.
Installation bolt hole 21 is further opened with the end cap 5.
The better embodiment of this patent is explained in detail above, but this patent is not limited to above-mentioned embodiment party
Formula, can also be on the premise of this patent objective not be departed from one skilled in the relevant art's possessed knowledge
Make a variety of changes.
