Description

Switch separation type energy disperser

Technical field

The utility model relates to a kind of buffering stopper for car, cage or skip bucket, has been specifically related to switch separation type energy disperser.

Background technology

Energy disperser is last link of elevator safety system, elevator break down or accident squat the end time play the effect of buffering.Thus the people alleviated in elevator or elevator is from direct shock.Buffer of elevator is mainly divided into: oleo gear, spring bumper and polyurethane bumper absorber, and wherein oleo gear is general owing to adapting to various speed tonnage demand Application comparison, and spring bumper is used for slower elevators.

And existing buffer of elevator; on the general pedestal that all can be arranged on immediately below car and counterweight; together with buffer switch is mounted in energy disperser, be all arranged in pit, when pit has water to enter; water starts to rise and does not cross buffer switch; because buffer switch is electronic machine, once be soaked in water, be easy to make switching damage; thus cause last safety guard malfunctioning, certain hidden danger is existed to elevator safety reliability service.

Utility model content

The utility model is intended to provide a kind of switch separation type energy disperser that buffer switch can not be immersed in water.

Switch separation type energy disperser in this programme, comprise the energy disperser being located at well pit, well enclosure is provided with guide rail, the top of energy disperser is provided with car, and car is slidably connected on guide rail, and the column of described car sedan-chair frame is provided with and hits bow, guide rail is provided with buffer switch, described buffer switch is positioned at and hits on the motion track of bow, buffer switch level attitude higher than pit, and lower than hitting the bottom of bow.

The know-why of this programme and beneficial effect are: switch separation type energy disperser, comprises the energy disperser being located at well pit, and energy disperser is the important safety component of lift facility, lift car fall or rush to summit dangerous time shield; Car is used to carry passenger's; Well enclosure is provided with guide rail, and lift car is slidably connected on guide rail by leading boots, pumps, so that passenger is downstairs upper; The column of the sedan-chair frame of lift car is provided with and hits bow, hit bow for fall at lift car dangerous time, play the effect of cushion at collision switch; Guide rail is provided with buffer switch, and buffer switch is positioned at and hits on the motion track of bow, when lift car fall dangerous time, hit bow cushion at collision switch, buffer switch action, by thus the electric power supply of electric-control system that runs of all control elevators that breaks, and by elevator brake; To ensure elevator brake; Buffer switch level attitude is higher than pit, when pit is intake, water starts to rise, be raised to pit top always, and flow away from ground, now pit overflows water, but buffer switch is higher than pit, therefore water can not have buffer switch, and was soaked damage, thus ensure that last safety guard reliability service; Buffer switch, lower than the bottom of hitting bow, ensure that when elevator normally runs, and hitting bow can not cushion at collision switch.

Further, the distance of hitting between bow and buffer switch is less than or equal to the distance between car diapire and energy disperser.When lift car fall dangerous time, car will move downward, move to the top that car bottom does not also contact or just contacts energy disperser always, hit bow and start cushion at collision switch, buffer switch action, thus the electric power supply of the electric-control system of all control elevators operation of breaking, make elevator brake, ensure the safety of elevator and people.

Further, energy disperser is water bumper.Hydraulic draft gear belongs to energy-dissipating type parts, by hydraulic oil, most of kinetic transformation is become heat energy when being subject to the high-speed impact of car or counterweight, thus substantially reduces impact power, therefore is applicable to the elevator of any speed specification.

Accompanying drawing explanation

Fig. 1 is the schematic diagram of the utility model embodiment switch separation type energy disperser.

Detailed description of the invention

Below by detailed description of the invention, the utility model is described in further detail:

Reference numeral in Figure of description comprises: water bumper 1, sedan-chair frame 2, guide rail 3, hit bow 4, buffer switch 5, car 6, pedestal 7.

Embodiment is substantially as shown in Figure 1: switch separation type energy disperser, comprise the water bumper 1 being positioned at well pit, water bumper 1 is arranged on the pedestal 7 of pit bottom, well enclosure is provided with guide rail 3, lift car 6 lead boots and guide rail 3 sliding block joint, hit bow 4 and comprise transverse plate and vertical plate, transverse plate by bolt on the column 2 of sedan-chair frame, vertical plate is vertically set on one end of transverse plate, transverse plate and vertical plate one-body molded, the bottom of vertical plate is the tilted shape of right low left high, the high side of vertical plate bottom is near buffer switch 5 side, guide rail 3 is provided with buffer switch 5, buffer switch 5 be positioned at hit bow 4 motion track on, buffer switch 5 level attitude is higher than pit, and lower than hitting the bottom of bow 4, the distance of hitting between bow 4 and buffer switch 5 is less than or equal to the distance between car 6 diapire and energy disperser.

When lift car 6 fall dangerous time, car 6 moves downward on guides 3 by leading boots, move to the top that car 6 bottom does not also contact or just contact is positioned at the water bumper 1 on pit bottom pedestal 7 always, the bow 4 that hits be positioned on the column 2 of the sedan-chair frame of lift car 6 starts to clash into the buffer switch 5 be positioned on guide rail 3, buffer switch 5 action, the electricity of the electric-control system that all control elevators can be made to run breaks, thus make elevator brake, ensure that the not damaged and passenger of elevator personal safety; Buffer switch 5 level attitude, higher than pit, ensure that when to overflow water in pit, buffer switch 5 can not had by water logging, and causes damage, and then ensure that last safety guard reliability service.

After installing buffer switch 5, what coordinate with it in installation hits bow 4, the setting of transverse plate, be convenient to the distance adjusting vertical plate and buffer switch 5, the shape of vertical plate bottom right low left high, is convenient to the button of buffer switch 5 to press, thus ensures that buffer switch 5 normally runs; Hit bow 4 to be threaded on the column of sedan-chair frame, be convenient to disassemble on the column hitting bow 5 and be arranged on sedan-chair frame or from the column of sedan-chair frame; The setting of pedestal 7, can by water bumper 1 stable position in pit bottom.

Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in specification sheets etc. record the content that may be used for explaining claim.
