Background technology
Buffer of elevator is to provide the elevator car safety of last a kind of safety guard-safeguard, and it is arranged in the well pit of elevator, is positioned at immediately below car and counterweight.When elevator is in motion up or down; due to wire cable rupture, traction friction force, brake sticking brake power is not enough or control system is malfunctioning and surmount terminal stop bottom or top layer time; will by energy disperser buffer action; to avoid lift car or counterweight directly hit the end or rush to summit, the safety of protection passenger and equipment.
Buffer of elevator is fixedly mounted by base when mounted.Fig. 1 and Fig. 2 depicts the Height Adjustable buffer of elevator base of a kind of prior art, it comprise be fixed on ground lower base 1, can be arranged on to up-down adjustment upper base 2 on lower base 1 and connect the bolt 3 of lower base 1 and upper base 2.Lower base 1 and upper base 2 install the bottom-to-top-height of this buffer of elevator base of rear formation.Lower base 1 comprises base plate 4 and lower cylinder 5, upper base 2 comprises top board 6 and upper cylinder 7, it is interior and fastening by bolt 3 that upper cylinder 7 can be plugged on to up-down adjustment lower cylinder 5, also locked by bolt 8 between upper cylinder 7 with lower cylinder 5 and be connected, the height adjustment of bolt 8 by selecting the position of bolt hole to carry out buffer of elevator base.
But the shearing force can born due to bolt 8 is limited, the buffer of elevator base of prior art is only applicable to the less elevator of cushion effect, is not suitable for the Cargo Lift that cushion effect is larger.
Summary of the invention
In order to overcome the defect of prior art, the object of this invention is to provide a kind of carrying out and highly regulating the buffer of elevator base that also can bear larger cushion effect.
For achieving the above object, the invention provides a kind of Height Adjustable buffer of elevator base, comprise the lower base being fixed on ground, can be arranged on to up-down adjustment the upper base on described lower base and connect the fastener of described lower base and described upper base, described lower base comprises base plate and lower cylinder, described upper base comprises top board and upper cylinder, described upper cylinder can be plugged on to up-down adjustment in described lower cylinder and to be fixedly connected with by described fastener, it is characterized in that: described lower cylinder is also provided with height regulating ring, the lower end of described height regulating ring is supported on described lower cylinder, the upper end of described height regulating ring supports described top board.
In further improving, the height regulating ring described at least two is disposed with from bottom to up in the upper end of described lower cylinder, in described at least two height regulating rings, the height regulating ring of bottom is supported on described lower cylinder, the height regulating ring of the top supports described top board, and each described height regulating ring is all set on the periphery of described upper cylinder.
Preferably, the external diameter of each described height regulating ring is identical with the external diameter of described lower cylinder.
More preferably, the wall thickness of each described height regulating ring is identical with the wall thickness of described lower cylinder.
Preferably, the axial height of each described height regulating ring is all identical or part is identical or not identical.
Preferably, the inwall of each described height regulating ring is provided with the coordinating block matched with the periphery of described upper cylinder.
More preferably, the quantity of the coordinating block on the inwall of each described height regulating ring is multiple, and multiple described coordinating block is spaced apart along same even circumferential.
Compared to prior art, Height Adjustable buffer of elevator base provided by the invention, upper base is supported by the height regulating ring be arranged between lower base and upper base, owing to being ring cross-section transmission cushion effect, compressive property strengthens greatly, be applicable in highspeed passenger lift or Cargo Lift, and can rely on and select the height regulating ring of differing heights to regulate the whole height of buffer of elevator base, very convenient.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.
Refer to Fig. 3 to Figure 10, a kind of Height Adjustable buffer of elevator base, comprise be fixed on ground lower base 10, can be arranged on to up-down adjustment upper base 20 on lower base 10 and connect the fastener of lower base 10 and upper base 20, formed the whole height of this buffer of elevator base by lower base 20 and upper base 10.Lower base 10 comprises base plate 40 and lower cylinder 50, and upper base 20 comprises top board 60 and upper cylinder 70, and buffer of elevator is installed on top board 60.Upper cylinder 70 can be plugged on to up-down adjustment in lower cylinder 50 and to be fixedly connected with by described fastener.In the present embodiment, fastener is bolt 30, and the excircle of lower cylinder 50 offers 3 screws 31 along same circumferencial direction uniform intervals, and bolt 30 is each passed through screw 31 and is pushed against on the outer circumference surface of cylinder 70.
Buffer of elevator base in the present embodiment comprises multiple available height regulating ring 90, and the axial height of each height regulating ring 90 is all identical.Certainly in other embodiments, the height of multiple height regulating ring 90 also can be set to not identical, or the height of the height regulating ring 90 of partial amt is identical, the height of the height regulating ring 90 of partial amt is different, can need to carry out combination in any according to the whole height of base.In the present embodiment, the external diameter lower cylinder 50 being disposed with identical height regulating ring 90, two the height regulating ring 90 of two axial heights from is down all identical with the external diameter of lower cylinder 50, and the wall thickness of two highly regulating rings 90 is also all identical with lower cylinder 50.The height regulating ring 90 of bottom is supported on the upper end of lower cylinder 50, and height regulating ring 90 roof supporting 60 of the top, each height regulating ring 90 is all set on the periphery of described upper cylinder 70.
The inwall of each height regulating ring 90 is welded with the coordinating block 100 matched with the periphery of upper cylinder 70.The quantity of the coordinating block on the inwall of each height regulating ring 90 is 3, and 3 coordinating blocks 100 are spaced apart along same even circumferential.One end outer circumference surface of the lower cylinder 50 of upper cylinder 70 insertion is also intervally distributed with 3 coordinating blocks 100 along same even circumferential.The effect of coordinating block 100 makes to cooperatively interact between cylinder 70 and lower cylinder 50, makes to match between height regulating ring 90 and upper cylinder 70.
Buffer of elevator base of the present invention in use, when impulsive force acts on top board 60 from the top down, due to height regulating ring 90 roof supporting 60, and height regulating ring 90 is that circular ring section is stressed, the cushion effect that can bear is larger, can be applicable in highspeed passenger lift and Cargo Lift, more safe and reliable compared to prior art.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and implement according to this; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed within protection scope of the present invention.
