Description

A kind of platform lifting seat

Technical field

The present invention relates to bus platform, be specifically related to a kind of platform lifting seat.

Background technology

When rainy day or snow sky, bus platform can also provide the function of keeping off the rain or keeping off snow for people, existing bus platform seat not liftable, and this is when rainy day or snow sky, occupy the space in bus platform, the enable bus platform that enters enters people's minimizing of taking shelter from rain or keeping away snow.

Summary of the invention

For above-mentioned prior art Problems existing, the invention provides a kind of platform chair lift, this seat can drop to below ground in rainy day or snow sky, thus can provide sufficient space for the people taken shelter from rain or keep away snow.

The invention provides a kind of platform lifting seat, comprise the seat that cross section is rectangle, be arranged on the accommodation space of below ground surface, described accommodation space upper end has the opening measure-alike with described seat, support is provided with bottom described accommodation space, described support is made up of a crossbeam and a column, crossbeam is flatly fixedly installed in accommodation space by column, the left and right sides of described crossbeam is respectively provided with a lifting unit symmetrically, described lifting unit comprises hydraulic cylinder, V-arrangement turning arm, bearing one and bearing two, the outer low inner high end being arranged on crossbeam obliquely of described bearing one, the outer low inner high bottom being arranged on crossbeam obliquely of bearing two, the lower end of bearing one is higher than the lower end of bearing two, the cylinder seat of hydraulic cylinder and the lower end of bearing two hinged, the flex point of V-arrangement turning arm and the lower end of bearing one hinged, the piston rod head of hydraulic cylinder and the lower end of V-arrangement turning arm hinged, the upper end of V-arrangement turning arm is with to be slidably arranged in the basifacial pedestal of chair hinged, be provided with the chute that cross section is swallow-tail form in the middle part of seat lower surface along its length, the upper end of described pedestal is provided with the guide rail that the cross section suitable with described oil groove is swallow-tail form, described seat two ends are provided with the positive stop one for limiting V-arrangement turning arm maximum angle symmetrically, and described chute is between two positive stops one.

For the ease of controlling the maximum lifting heights of seat, the position of described seat lower central is provided with the positive stop two for limiting described pedestal maximum sliding position inwards, and the thickness of positive stop two and the thickness sum of seat equal the distance of pedestal upper end distance ground surface.

The present invention can control by two lifting units the position that seat drops to drug equal with ground surface, it can also be made to be raised to more than earth's surface have a rest for people, this seat can be elevated as required, thus can need during larger space, seat to be declined in bus platform, thus provide larger space for the people in bus platform.

Detailed description of the invention

Below in conjunction with accompanying drawing, the invention will be further described.

As depicted in figs. 1 and 2, a kind of platform lifting seat, comprise the seat 11 that cross section is rectangle, be arranged on the accommodation space 1 of below ground surface, described accommodation space 1 upper end has the opening measure-alike with described seat 11, support is provided with bottom described accommodation space 1, described support is made up of a crossbeam 2 and a column 3, crossbeam 2 is flatly fixedly installed in accommodation space 1 by column 3, the left and right sides of described crossbeam 2 is respectively provided with a lifting unit symmetrically, described lifting unit comprises hydraulic cylinder 4, V-arrangement turning arm 5, bearing 1 and bearing 27, the outer low inner high end being arranged on crossbeam 2 obliquely of described bearing 1, the outer low inner high bottom being arranged on crossbeam 2 obliquely of bearing 27, the lower end of bearing 1 is higher than the lower end of bearing 27, the cylinder seat of hydraulic cylinder 4 and the lower end of bearing 27 hinged, the flex point of V-arrangement turning arm 5 and the lower end of bearing 1 hinged, the piston rod head of hydraulic cylinder 4 and the lower end of V-arrangement turning arm 5 hinged, the upper end of V-arrangement turning arm 5 is with hinged at the pedestal 8 of seat 11 bottom slidably, pedestal 8 coordinates with seat 11 lower slide, be provided with the chute that cross section is swallow-tail form along its length in the middle part of seat 11 lower surface, the upper end of described pedestal 8 is provided with the guide rail that the cross section suitable with described oil groove is swallow-tail form, described seat 11 two ends are provided with the positive stop 1 for limiting V-arrangement turning arm 5 maximum angle symmetrically, and described chute is between two positive stops 1.The position that seat drops to drug equal with ground surface can be controlled by two lifting units, it can also be made to be raised to more than earth's surface have a rest for people, this seat can be elevated as required, thus can need during larger space, seat to be declined in bus platform, thus provide larger space for the people in bus platform.

For the ease of controlling the maximum lifting heights of seat 11, the position of described seat 11 lower central is provided with the positive stop 2 10 for limiting described pedestal 8 maximum sliding position inwards, and the thickness of positive stop 2 10 and the thickness sum of seat 11 equal the distance of pedestal upper end distance ground surface.Positive stop 2 10 have sufficiently long length can ensure its two ends respectively to pedestal 8 in its both sides all play position-limiting action.

During use, the hydraulic cylinder 4 of two lifting units is synchronized with the movement, when rainy day or snow sky, retracting with entering control two hydraulic cylinders 4, driving seat 11 to move downward by V-arrangement turning arm 5, when pedestal 8 outwards slides into the position of positive stop 1, the upper surface of seat 11 drops to mutually concordant with ground surface, meanwhile, the positive stop 2 10 of seat 11 can prop up the upper end at support, can ensure that seat 11 still can have good load bearing stength after decline like this; When needs seat normally uses, the piston rod simultaneously controlling two hydraulic cylinders 4 is protruding, is with moving base 8 to slide inwards, when pedestal 8 arrives to the position of positive stop 2 10 by V-arrangement turning arm 5, seat 11 rises to maximum height more than ground surface, and this seat can normally use.
