Description

A kind of elevator pit device

Technical field

The utility model relates to a kind of elevator pit device, belongs to technical field of elevator equipment.

Background technology

Current vertical lift lift facility has and uses very widely, the safety run in order to ensure elevator and reliability, run channel bottom at elevator all to need to build the pit corresponding with elevator car structure, and in pit, establish corresponding protective device, in presently used elevator pit, protective device is often only the bumpar post that at least four can be played buffer action, the structure of this protective device is simple, serviceability is good, maintenance cost is cheap, therefore usage space very is widely had, but find in actual use, because the buffer capacity of bumpar post is limited, therefore when the descending running velocity of elevator is too fast, often lift car is produced to the impact strengthened, also effectively cannot absorb the kinetic energy that elevator cage operation produces simultaneously, therefore easy comparatively havoc is caused to elevator structure, and the safety of elevator interior personnel and article is constituted a serious threat, can not put out timely phenomenons on fire such as the naked lights produced because of elevator faults simultaneously, therefore for this present situation, in the urgent need to developing a kind of elevator pit device, with the needs that satisfied reality uses.

Utility model content

For the deficiency that prior art exists, the utility model provides a kind of elevator pit device, this novel stable and reliable operation, to elevator cage operation impact energy, there is good absorption and releasing effect, and correction guiding can be carried out to elevator car position, simultaneously, separately the car phenomenon on fire caused because of faults such as car fall can be put out in time, thus effectively improve stability and the safety of elevator cage operation.

To achieve these goals, the utility model realizes by the following technical solutions:

A kind of elevator pit device, comprise positioning base, buffer table, cushioning supportive mechanism, bumpar post, guidepost, pillar stiffener, elastic buffering pad and buffering gas bag, base is parallel with elevator pit upper surface, uniform at least four pillar stiffeners of base lower surface, pillar stiffener top is connected with base, bottom is embedded in elevator melt pit foundation, elastic buffering pad is separately established to fill between base lower surface and elevator melt pit foundation upper surface, another uniform deformation hole in elastic buffering pad, buffering gas bag is separately embedded in deformation hole, buffer table is positioned at directly over base, and to be connected with base by cushioning supportive mechanism and to be parallel to each other, bumpar post at least four is also uniformly arranged on buffer table upper surface, and with buffer table vertical distribution, bumpar post comprises basic shaft, buffering shaft, recoil spring and elastic buffer block, wherein basic shaft end is connected with buffer table, front end is connected with buffering shaft by recoil spring, and basic shaft is gentle rushes shaft axis and be distributed in same rectilinear direction, recoil spring two ends are coated on basic shaft front end appearance and buffering shaft end appearance respectively, buffering shaft front end surface and distal end faces all establish elastic buffer block, guidepost at least four, and it is uniform around buffer table center line, guidepost end and buffer table hinged, front end establishes elastic guide to take turns, angle adjusting mechanism is separately established in guidepost and buffer table hinged place.

Further, it is 2/3-3/4 of pillar stiffener bottom-to-top-height that described pillar stiffener is embedded in elevator melt pit foundation inner height.

Further, described deformation hole is regular hexagon structure, and with base vertical distribution or parallel distribution.

Further, described cushioning supportive mechanism is that hydraulic pressure or air pressure drive scissors-type lifting.

Further, described base and buffer table comprise vertical beam and crossbeam, wherein vertical beam and the mutual vertical distribution of crossbeam, and form lattice-shaped planar structure.

Further, be high pressure nitrogen in described buffering gas bag, and air pressure is at least 1.5 times of standard atmosphere.

This novel stable and reliable operation, to elevator cage operation impact energy, there is good absorption and releasing effect, and correction guiding can be carried out to elevator car position, simultaneously, separately the car phenomenon on fire caused because of faults such as car fall can be put out in time, thus effectively improve stability and the safety of elevator cage operation.
