And with terraced leg angle adjustable, the oblique pull supporting mechanism for stablizing terraced leg.
Further, the oblique pull supporting mechanism include top with terraced leg is hinged, bottom is separated with terraced leg and bottom end with
Cable-stayed type support rod in the middle part of the supporting leg and connection supporting leg of face contact with terraced leg lower part, one far from terraced leg of support rod
End is hinged on supporting leg, and at least one end of support rod can be moved up and down along supporting leg or terraced leg.
Further, the one of the close terraced leg of pipe clamp there are two being arranged on every terraced leg, the supporting leg and support rod
End is respectively hinged on the pipe clamp of corresponding position.
Further, one end of the pipe clamp is equipped with fastening bolt, and the other end is equipped with free bearing.
Further, the pipe clamp being connected with supporting leg is located between two ladder bars of terraced leg bottom.
Further, the lower part of the supporting leg and the side towards terraced leg offer sliding slot, are equipped with and support in sliding slot
The coaxial lead screw of leg；The side backwards to terraced leg of the supporting leg offers adjustment hole along the radial direction of supporting leg, and adjusts
Hole is located at the top of sliding slot and is connected to sliding slot, and rotary-regulating valve is coaxially provided in adjustment hole；The top of the lead screw is coaxially arranged with
First angular wheel, the inner end of regulating valve are equipped with the second angular wheel being meshed with the first angular wheel；Match on the lead screw
It closes and is equipped with sliding block, and support rod is hinged on sliding block far from one end of terraced leg.
Due to using above technical scheme, the invention technological progress is as follows.
Ladder of the invention is basic prototype with traditional ladder, is respectively arranged on four terraced legs of ladder a set of by supporting
Leg and support bar group at rotatable and with terraced leg angle adjustable triangle oblique pull supporting mechanism, can terraced leg be that axis rotates
Certain angle can also easily adjust the angle of supporting leg and terraced leg, and therefore, it is multiple that ladder of the invention is highly suitable for mountainous region
The operation maintenance of photovoltaic plant in miscellaneous landform.
Structure of the invention is simple, easy to operate, and dimension pipe personnel can make respectively every terraced leg according to mountain topography
It is corresponding to adjust, suitable support point is adjusted out, so that four terraced legs can provide preferable support effect to ladder, is made
It is good with stability, expand the scope of application of ladder.

Specific embodiment
Below in conjunction with specific embodiment, the present invention will be described in further detail.
Embodiment 1:
As shown in Figure 1, the invention discloses a kind of ladder suitable for mountainous region complicated landform, including top is connected by hinge 5
Two ladders 1 together, each ladder 1 is including two terraced legs and more ladder bars being located between two terraced legs；Every ladder
The lower part of leg be respectively provided with one it is rotatable and with terraced leg angle adjustable, the oblique pull supporting mechanism for stablizing terraced leg.Oblique pull support
Mechanism include top with terraced leg is hinged, bottom is separated with terraced leg and bottom end with face contact supporting leg 3 and connect supporting leg
One end far from terraced leg of the cable-stayed type support rod 4 at middle part and terraced leg lower part, support rod 4 is hinged on supporting leg 3, and is supported
At least one end of bar 4 can be moved up and down along supporting leg 3 or terraced leg, to form stable triangular support structure to terraced leg.
Supporting leg 3 and support rod 4 on every terraced leg can not only be opened and closed relative to the ladder leg, additionally it is possible to be with the ladder leg
Axis rotates a certain angle.In the present embodiment, supporting leg 3 and support rod 4 are opened and closed relative to terraced leg and rotation is managed by two
What folder 2 was realized: be arranged on every terraced leg there are two pipe clamp 2, one end of pipe clamp 2 is equipped with fastening bolt 6, and the other end is equipped with hinge
Seat.One end close to terraced leg of supporting leg 3 and support rod 4 is respectively hinged on the pipe clamp 2 of corresponding position.Fastening bolt 6 is used for
Adjust the clamping force size of the terraced leg of 2 pairs of pipe clamp, after unclamping fastening bolt 6, pipe clamp 2 can be moved up and down in terraced leg, can also realize with
Terraced leg rotates a certain angle for axis；After the direction and angle of supporting leg 3 and support rod 4 are adjusted, tightening fastening bolt 6 will
Pipe clamp 2 is fixed on terraced leg, and supporting leg 3 and support rod 4 can provide terraced leg stable triangle oblique pull support.
In use, needing ladder being placed on suitable position according to dimension pipe first, the flange splint of two ladders 1 is adjusted
Angle；Four respective oblique pull supporting mechanisms of terraced leg for adjusting separately two ladders 1, first unclamp two pipe clamps 2 on terraced leg, relatively
In terraced leg rotational support leg 3 and support rod 4, while opening and closing supporting leg 3 and moving up and down so that supporting leg 3 terraced leg peripherally
A suitable impetus is found on face, to form firm triangle oblique pull supporting mechanism to terraced leg.
Moreover, after ladder first adjusts the direction and angle of supporting leg 3 and support rod 4 before use, it also need not be complete
Fastening bolt 6 is tightened, in this way, working as ladder in use, due to bearing biggish pressure, and under unbalance stress, ladder is also
There may be certain displacements, and since pipe clamp 2 is not completely fixed, pipe clamp 2 can also occur small-scale movement or be turned on terraced leg
Dynamic, the direction and angle of supporting leg 3 and support rod 4 are slightly adjusted, and pipe clamp 2 is kept fixed under the action of frictional force, with
Adaptability is that terraced leg provides better support.
The pipe clamp 2 being connected with supporting leg 3 is located between two ladder bars of terraced leg bottom.Due to the pipe clamp 2 be located at it is another
The top of a pipe clamp 2, in this way when pipe clamp 2 unclamps, when adjustment, entire support construction would not fall off from terraced leg.
Embodiment 2:
On the basis of embodiment 1, one end far from terraced leg of support rod 4 can be moved up and down along supporting leg 3.Under supporting leg 3
Portion and side towards terraced leg offer sliding slot, are equipped with the lead screw 33 coaxial with supporting leg 3 in sliding slot；The back of the supporting leg 3
Adjustment hole is offered along the radial direction of supporting leg 3 to the side of terraced leg, and adjustment hole is located at the top of sliding slot and connects with sliding slot
It is logical, rotary-regulating valve 32 is coaxially provided in adjustment hole；The top of the lead screw 33 is coaxially arranged with the first angular wheel, regulating valve 32
Inner end is equipped with the second angular wheel being meshed with the first angular wheel；Cooperation is equipped with sliding block 34 on the lead screw 33, and props up
Strut 4 is hinged on sliding block 34 far from one end of terraced leg.
Rotary-regulating valve 32 is rotated, then by intermeshing two angular wheels, lead screw 33 can be driven to rotate together, and by silk
The linear slide for being converted into sliding block 34 of thick stick 33, it is more preferable to provide so that the folding angle to support rod 4 is finely adjusted
Support.
As shown in figure 5, A point is hinge joint of the support rod 4 on supporting leg 3, B point is that support rod 4 is hinged on terraced leg
Point, C point are hinge joint of the supporting leg 3 on terraced leg, and D point is supporting leg 3 to impetus on the ground.Wherein, C point and B point
Upper and lower position on terraced leg is adjustable, and A point and C point and the distance between B point and C point are adjustable, changes the side of triangle ABC
Position and while AC and while BC length, the triangle oblique pull supporting mechanism that supporting leg 3 and support rod 4 can be made to be formed, to terraced leg
Stable support is provided with ladder.
