Specific embodiment

With reference to the accompanying drawings and examples, this utility model is expanded on further.In the following detailed description, only pass through to say Bright mode describes some one exemplary embodiment of the present utility model.Undoubtedly, those of ordinary skill in the art is permissible Recognize, in the case of without departing from spirit and scope of the present utility model, can by with various different in the way of to described Embodiment is modified.Therefore, accompanying drawing and description are inherently illustrative, rather than for limiting the protection of claim Scope.

This utility model embodiment is related to a kind of elevator with hoistway buffer unit, as shown in Figure 1, including internal recessed It is formed with the hoistway 1 of pit 11, and the car 2 being adapted with hoistway 1, also include the well being arranged between car 2 and pit 11 Road buffer unit, described hoistway buffer unit corresponds to four angles arrangement of described car 2, elevator of the present utility model other Structure is identical with the elevator of the prior art with hoistway 1, will not be described here.

In the present embodiment, combined shown in Fig. 2 by Fig. 1, hoistway buffer unit includes guide part 3, and wherein, guide part 3 includes One end is fixed on the guide pillar 31 of car 2 bottom, and holds the other end insertion making guide pillar 31 and carry out slide-and-guide to guide pillar 31 Guide pin bushing 32, be provided with the first buffer part 321 that after guide pillar 31 motion puts in place, guide pillar 31 is entered with row buffering in the guide pin bushing 32；And Second buffer part 33, the second buffer part 33 is arranged in pit 11, and the second buffer part 33 includes being formed with from one guide pin bushing 32 bottom Portion extends to the guide pipe 331 of the guide path of another guide pin bushing 32 bottom, and adapts in guide path, along guide path Multiple rolling elements 332 of length direction arrangement, in the present embodiment, rolling element 332 is ball.The present embodiment guide pillar 31 is respectively It is fixed on four at the angle of car 2 bottom four, when car 2 falls phenomenon, when moving to extreme position, in guide pin bushing 32 Bottom is provided with the rubber blanket that guide pillar 31 is entered with row buffering.In the present embodiment, guide pipe 331 is arranged in parallel two.

By arranging hoistway buffer unit between car 2 and pit 11, after guide pillar 31 motion puts in place, guide pillar 31 is entered First buffer part 321 of row buffering and the setting being arranged at the second buffer part 33 in pit 11, can fall in car 2 During situation, multi-buffer to car 2 is done step-by-step, buffering effect preferably, has preferable using effect.

In the present embodiment, for making buffering effect more preferably, between each rolling element 332, leave gap, meanwhile, for increase guide pin bushing 32 with The contact area of rolling element 332, is formed with guide pin bushing 32 bottom and holds the depressed part 322 that rolling element 332 is partially submerged into, the present embodiment In, guide pipe 331 side is fixed in pit 11 via the 3rd buffer part 34, by the first buffer part 321, the second buffer part 33 And the 3rd buffer part 34 cooperation, can to the buffering effect of car 2 more preferably, in the present embodiment, the 3rd buffer part 34 is rubber Pad.

In the present embodiment, the first buffer part 321, the second buffer part 33 and the 3rd buffer part 34 are made by elastomeric material, Certain first buffer part 321 and the 3rd buffer part 34 can also be made up of leaf spring.

The work process that this utility model has the elevator of hoistway 1 buffer unit is as follows：

When car 2 falls, car 2, under the drive of guide pillar 31, slides, when moving to extreme position in guide pin bushing 32 When, guide pillar 31 can once be buffered, subsequently successively in the second buffer part in the presence of the first buffer part 321 in guide pin bushing 32 33rd, enter row buffering in the presence of the 3rd buffer part 34, via above-mentioned three-level buffering, the impact to car 2 can be slowed down, make elevator Buffering effect preferable.

The foregoing is only the schematic specific embodiment of this utility model, be not limited to model of the present utility model Enclose.Any those skilled in the art, done equivalent change on the premise of without departing from design of the present utility model and principle Change and modification, the scope of this utility model protection all should be belonged to.
