Abstract
The invention belongs to coal mine working face supporting construction equipment and particularly relates to a ladder pedal. The ladder pedal comprises a ladder body welded by a steel plate, steps of the ladder body are provided with base plates, the base plates are arranged in an overturning mode along rotating shafts parallel to the width direction of the ladder body, and the included angle between each base plate and the corresponding step surface of the ladder body is adjustable. The base plates are in movable connection with the ladder body, when the dip angle of the work surface is changed, the base plates can be always parallel to the horizontal surface by adjusting the base plates so as to be adapted to changes of dip angles of different terrains. Safety performance of the pedal is improved, and meanwhile construction difficulty and the construction cost are lowered.

One end of hinged-support rides on step surface or the step turning of ladder body.
Wherein one end of described backing plate is hinged with a moveable hinge bearing, described moveable hinge bearing and ladder body
Step surface is flexibly connected, and before and after making moveable hinge bearing on step surface, position is adjustable；Described backing plate is away from work
One end of dynamic hinged-support rides on facade or the step turning of ladder body.
Described moveable hinge bearing includes that two clamping plates, described two clamping plate are clamped vertical respectively inside and outside facade
Face, 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, rank
Ladder pedal is connected with the base plate of hydraulic support by this connecting portion.
It is an advantage of the current invention that: backing plate is to be flexibly connected with ladder body, when work surface inclination angle changes
Time, 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 the security performance of pedal, reduce difficulty of construction and construction cost simultaneously.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail.
In describing the invention, it should be noted that term " on ", D score, "front", "rear", " interior ",
Orientation or the position relationship of the instruction such as " outward " they are based on orientation shown in the drawings or position relationship, merely to
It is easy to describe the present invention and simplification description rather than instruction or the device of hint indication or element must have spy
Orientation structure and operation, be therefore not considered as limiting the invention.
As shown in Figure 1, 2, a kind of stair tread, including by the ladder body 10 of Plate Welding, described
The step of ladder body 10 is provided with backing plate 11, and described backing plate 11 is along being parallel to ladder body 10 width
Rotating shaft upset arrange, make the angle between described backing plate 11 and the step surface 102 of ladder body 10 adjustable.
Backing plate 11 is to be flexibly connected with ladder body 10, when work surface inclination angle changes, and can be by adjusting
Backing plate 11 makes backing plate 11 all the time and plane-parallel, to adapt to the change of pitch angle of different terrain.Improve and step on
The security performance of plate, reduces equipment installation difficulty and installation cost simultaneously.
Embodiment 1
As shown in Figure 1, 2, 3, as the preferred embodiments of the present invention, wherein one end of described backing plate 11 with
