Angle the most constantly changes, but pedal design angle is unchanged, causes pedal run-off the straight, therefore is unfavorable for that personnel are above
Operation, walking, the security incident such as easily cause that personnel twist leg.
Utility model content
Technical problem to be solved in the utility model be to provide a kind of stair tread that can adapt to topography variation with
And the hydraulic support containing this pedal.
This utility model solves above-mentioned technical problem by the following technical solutions:
A kind of stair tread, including by the ladder body of Plate Welding, the step of described ladder body is provided with pad
Plate, described backing plate arranges along the rotating shaft upset being parallel to ladder body width direction, makes the step of described backing plate and ladder body
Angle between face is adjustable；Wherein one end of described backing plate is hinged with a moveable hinge bearing, and described moveable hinge bearing is with ladder originally
The facade of body or step surface are flexibly connected, make moveable hinge bearing height on facade or on step surface before and after position can
Adjust.
Described backing plate rides on step surface or the step turning of ladder body away from one end of moveable hinge bearing.
Described backing plate rides on facade or the step turning of ladder body away from one end of moveable hinge bearing.
Described moveable hinge bearing includes that two clamping plates, described two clamping plate clamp facade respectively inside and outside facade, and
Pass through bolt presses；Clamping plate outside described backing plate and facade are hinged.
The surface of described backing plate is provided with for anti-skidding concave convex texture.
Described clamping plate are provided with the flank of tooth for increasing friction force with the plate face of facade laminating.
A kind of hydraulic support containing described stair tread, the bottom of described stair tread is provided with connecting portion, stair tread
It is connected with the base plate of hydraulic support by this connecting portion.
The utility model has the advantage of: backing plate is to be flexibly connected with ladder body, when work surface inclination angle changes,
Can make backing plate all the time and plane-parallel, to adapt to the change of pitch angle of different terrain by adjusting backing plate.Improve pedal
Security performance, reduces difficulty of construction and construction cost simultaneously.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in detail.
In description of the present utility model, it should be noted that term " on ", D score, "front", "rear", " interior ", " outward " etc.
Orientation or the position relationship of instruction are based on orientation shown in the drawings or position relationship, are for only for ease of description this utility model
Describe with simplification rather than indicate or imply that the device of indication or element must have particular orientation structure and operate, the most not
It is understood that as to restriction of the present utility model.
As shown in Figure 1, 2, a kind of stair tread, including by the ladder body 10 of Plate Welding, described ladder body
The step of 10 is provided with backing plate 11, and described backing plate 11 overturns along the rotating shaft being parallel to ladder body 10 width and arranges, and makes institute
State the angle between the step surface 102 of backing plate 11 and ladder body 10 adjustable.Backing plate 11 is to be flexibly connected with ladder body 10, when
When work surface inclination angle changes, can make backing plate 11 all the time and plane-parallel, to adapt to differently by adjusting backing plate 11
The change of pitch angle of shape.Improve the security performance of pedal, reduce equipment installation difficulty and installation cost simultaneously.
Embodiment 1
As shown in Figure 1, 2, 3, as preferred embodiment of the present utility model, wherein one end of described backing plate 11 is movable with one
Hinged-support 12 is hinged, and described moveable hinge bearing 12 is flexibly connected with the facade 102 of ladder body 10, makes moveable hinge bearing 12 vertical
Height adjustable on face 102；Described backing plate 11 away from one end of moveable hinge bearing 12 ride over ladder body 10 step surface 101 or
On step turning.
Preferably, as it is shown on figure 3, described moveable hinge bearing 12 includes two clamping plates 121, described two clamping plate 121 respectively from
Clamp facade 102 inside and outside facade 102, and compressed by bolt 122；Clamping plate outside described backing plate 11 and facade 102
121 is hinged.Two clamping plate 121 are sewn on ladder body 10 facade by the bolt 122 of diameter 12mm, described backing plate 11 and clamping plate
121 pass through hinged joint.Preferably, the surface of described backing plate 11 is provided with for anti-skidding concave convex texture；Described clamping plate 121 are with vertical
