User, which helps, to hold.Escalator can be walk forever to direction, but majority can according to needs such as time, the stream of peoples, by
Administrative staff control direction of travel.
Currently, there is the public facility up and down such as escalator, Lift & Stairs in major public place, especially with escalator
It is more.Especially at the train station, specially passenger is pushed on train by promising people with mobility problems's offer using wheelchair in railway station
Service, it is red for using staircase upstairs or downstairs, station staff does not use at present, because of existing wheelchair
It steadily cannot upwardly or downwardly be run on staircase.
Utility model content
A kind of the problem of for background technology, it is proposed that wheelchair can be used for staircase.
The utility model is addressed by following technical proposals：A kind of wheelchair can be used for staircase, including with ordinary wheel
The consistent vehicle body of chair, it is characterised in that：Vehicle body is coated on vehicle frame, and front wheel adjusting device, the front-wheel tune are provided on vehicle frame
Regulating device includes the linear guide mounted on vehicle frame front end, and the linear guide has left and right two, embedding in the every the linear guide
There are two linear sliders for set, front wheel carrier are equipped in four linear sliders in left and right, the front wheel carrier lower part installation is there are two before
Wheel, the front-wheel are connected to by straight-bar on front wheel carrier, and compressed spring is nested on the straight-bar between the front-wheel and front wheel carrier,
The front wheel carrier is connected firmly by intermediate portrait with sliding block, the sliding block be connected with lead screw and can when lead screw rotates above and below transport
Dynamic, the lead screw lower part is supported by the spring bearing one on vehicle body, and top is by the spring bearing mounted on vehicle frame top
Two supports, the top of the lead screw are located at two lower part of spring bearing and are fixedly connected with driven wheel, and driven wheel passes through synchronous belt and driving wheel
It is connected, driving wheel connects firmly on servo motor, and servo motor is mounted on by servo motor holder on vehicle frame, pacifies in vehicle foreside
Equipped with range sensor.
Further, the driving wheel and the driven wheel are synchronizing wheel, the synchronous belt and the driving wheel and it is described from
Driving wheel is mating, and notch is provided on the vehicle body to realize that range sensor is earthward detected from inside.
Further, the back segment of the vehicle frame is equipped with trailing wheel, and spring, the range sensor are fitted without on the trailing wheel
It is connected with controller with the servo motor, the controller is mounted in electronic box, and the electronic box is mounted on frame downward, described
Power supply is also equipped in electronic box.
Further, the front wheel carrier and front-wheel can realize up and down motion under the action of lead screw, and range sensor is used for
The distance for detecting ground, when front-wheel moves to the staircase of rising, first by the upward power of staircase, this is front-wheel, compresses bullet
Spring is compressed, and range sensor detecting distance becomes smaller, and lead screw drives front wheel carrier to move upwards, to realize that vehicle body is still within water
Level state, when front-wheel moves to the staircase of decline, compressed spring is stretched, and range sensor detecting distance becomes larger, lead screw band
Dynamic front wheel carrier moves downward, to realize that vehicle body is still within horizontality.
The utility model has the advantage of realize wheelchair can upper and lower escalator, solve present in background technology
Traditional push chairs cannot achieve staircase, the utility model up and down and only need a people that can realize wheelchair stair activity, have real
The promotional value on border.
Description of the drawings

Fig. 3 is the overall structure diagram two of the utility model.
Specific implementation mode
The utility model is described in further detail with specific implementation mode below in conjunction with the accompanying drawings：Such as Fig. 1 and Fig. 2 and figure
Shown in 3, a kind of wheelchair can be used for staircase includes the vehicle body 1 consistent with common wheelchair, it is characterised in that：Vehicle body 1 is coated on vehicle
On frame 2, front wheel adjusting device 3 is provided on vehicle frame 2, the front wheel adjusting device 3 includes that the straight line mounted on 2 front end of vehicle frame is led
Rail 3.1, the linear guide 3.1 have left and right two, and nested in the every the linear guide 3.1 there are two linear sliders 3.2, on a left side
Front wheel carrier 3.3 is installed, there are two front-wheels 3.4 for the installation of 3.3 lower part of the front wheel carrier, before described in right four linear sliders 3.2
Wheel 3.4 is connected to by straight-bar 3.5 on front wheel carrier 3.3, is nested on the straight-bar 3.5 between the front-wheel 3.4 and front wheel carrier 3.3
Compressed spring 3.6, the front wheel carrier 3.3 are connected firmly by intermediate portrait 3.3.1 with sliding block 3.7, the sliding block 3.7 and lead screw
3.8 are connected and can move up and down when lead screw 3.8 rotates, and 3.8 lower part of the lead screw is by the spring bearing on vehicle body 1
One 3.9 supports, top are located at support by the support of spring bearing 2 3.10 mounted on 2 top of vehicle frame, the top of the lead screw 3.8
2 3.10 lower part of bearing is fixedly connected with driven wheel 3.11, and driven wheel 3.11 is connected by synchronous belt 3.12 with driving wheel 3.13, actively
