A kind of stair tread, including the ladder body being welded by steel plate, the step of the ladder body are provided with pad
Plate, the backing plate overturn along the rotating shaft parallel to ladder body width direction and set, and make the step of the backing plate and ladder body
Angle between face is adjustable.2. stair tread according to claim 1, it is characterised in that：Wherein one end of the backing plate
It is hinged with a movable hinged-support, the movable hinged-support is flexibly connected with the facade of ladder body, makes movable hinged-support in facade
On height adjustable；The one end of the backing plate away from movable hinged-support is ridden on the step surface or step turning of ladder body.
Wherein one end of the backing plate is hinged with a movable hinged-support, the step surface of the movable hinged-support and ladder body
It is flexibly connected, makes front and back position of the movable hinged-support on step surface adjustable；Take the one end of the backing plate away from movable hinged-support
On the facade of ladder body or step turning.
The movable hinged-support includes two clamping plates, and two clamping plate clamps facade inside and outside facade respectively, and
Pass through bolt presses；The backing plate is hinged with the clamping plate on the outside of facade.
The surface of the backing plate, which is provided with, is used for anti-skidding concave convex texture.
The plate face that the clamping plate is bonded with facade is provided with the flank of tooth for increasing friction force.
A kind of hydraulic support containing the stair tread, the bottom of the stair tread are provided with connecting portion, stair tread
It is connected by the connecting portion with the bottom plate of hydraulic support.
The advantage of the invention is that：Backing plate is to be flexibly connected with ladder body, can be with when working face inclination angle changes
Make backing plate all the time by adjusting backing plate and plane-parallel, to adapt to the change of pitch angle of different terrain.Improve the safety of pedal
Performance, while reduce difficulty of construction and construction cost.

Embodiment
The present invention is described in detail below in conjunction with accompanying drawing.
In the description of the invention, it is necessary to which explanation, term " on ", " under ", "front", "rear", " interior ", " outer " etc. indicate
Orientation or position relationship be based on orientation shown in the drawings or position relationship, be for only for ease of the description present invention and simplification retouched
State, rather than the device or element of instruction or hint meaning must have particular orientation construction and operate, therefore it is not intended that
Limitation of the present invention.
As shown in Figure 1, 2, a kind of stair tread, including the ladder body 10 being welded by steel plate, the ladder body
10 step is provided with backing plate 11, and the backing plate 11 overturns along the rotating shaft parallel to the width of ladder body 10 and set, and makes institute
The angle stated between backing plate 11 and the step surface 102 of ladder body 10 is adjustable.Backing plate 11 is to be flexibly connected with ladder body 10, when
When working face inclination angle changes, by adjusting backing plate 11 it can make backing plate 11 all the time and plane-parallel, to adapt to differently
The change of pitch angle of shape.The security performance of pedal is improved, while reduces equipment installation difficulty and installation cost.
Embodiment 1
As shown in Figure 1, 2, 3, it is hinged as the preferred embodiments of the present invention, wherein one end of the backing plate 11 and an activity
Seat 12 is be hinged, and the movable hinged-support 12 is flexibly connected with the facade 102 of ladder body 10, makes movable hinged-support 12 in facade
Height adjustable on 102；The one end of the backing plate 11 away from movable hinged-support 12 rides over the step surface 101 or platform of ladder body 10
On rank turning.
Preferably, as shown in figure 3, the movable hinged-support 12 includes two clamping plates 121, two clamping plate 121 respectively from
Facade 102 is clamped inside and outside facade 102, and is compressed by bolt 122；The backing plate 11 and the clamping plate in the outside of facade 102
