Abstract
The utility model relates to a rotatable middle support leg, including well landing leg upper strata, the below on well landing leg upper strata is equipped with well landing leg lower floor, forms a two -layer structure, be equipped with rotating flange between well landing leg upper strata and the well landing leg lower floor, rotating flange's upper and lower both ends are connected with well landing leg upper strata and well landing leg lower floor respectively, still include the screw rod, be equipped with the screw in the well landing leg lower floor, be equipped with curved hole on the well landing leg upper strata, screw spiro union in curved hole during the screw rod passes on the landing leg upper strata and the well landing leg lower floor still includes the nut, the nut is installed on the screw and is arranged in landing leg upper strata upper portion and is used for the screw rod spacingly with curved hole, through be equipped with curved hole on well landing leg upper strata, the screw of setting up in the well landing leg lower floor still can rotate when spacing not needing at will, passes curved hole and screw spiro union with the screw rod when needs are spacing, thereby the rethread nut reaches well landing leg upper strata and nut extrusion limited rotating's effect.
Description
Technical field
This utility model is related to a kind of rotatable middle supporting leg.
Background technology
Currently, Bridge Erector use working environment become increasingly complex, construction want condition for peace also different, erection
During sharp radius curve bridge, the particularly larger curved bridge of span, Bridge Erector is limited by itself huge body, often cannot be fitted
Should, greatly affected the progress constructed, and the unstability of the angle due to artificial force and force direction, also increase and apply
The difficulty of work and danger coefficient.
At present Chinese patent cn202247701u discloses a kind of rotatable middle supporting leg, including in supporting leg upper strata, described
The lower section on middle supporting leg upper strata is provided with middle supporting leg lower floor, forms a double-layer structure；Described middle supporting leg upper strata and middle supporting leg lower floor it
Between be provided with rotary flange, the upper and lower ends of described rotary flange are connected with middle supporting leg upper strata and middle supporting leg lower floor respectively.
Find through practice, though directly rotation is solved the problems, such as using rotary flange, can be convenient when using,
But unrestricted mechanism is limited to rotation and is positioned, and will also result in difficulty and the danger coefficient of construction on the contrary.
Content of the invention
This utility model mainly solves the technical problem existing for above-mentioned prior art, there is provided one kind can be to being rotated into
Row positioning and the rotatable middle supporting leg limiting.
To achieve these goals, the technical solution adopted in the utility model is: a kind of rotatable middle supporting leg, including in
Supporting leg upper strata, the lower section on described middle supporting leg upper strata is provided with middle supporting leg lower floor, forms a double-layer structure；Described middle supporting leg upper strata and
Be provided with rotary flange between middle supporting leg lower floor, the upper and lower ends of described rotary flange respectively with middle supporting leg upper strata and middle supporting leg lower floor
Connect, also include screw rod, described middle supporting leg lower floor is provided with screw, described middle supporting leg upper strata is provided with arc-shaped through-hole, described spiral shell
Bar passes through the arc-shaped through-hole on middle supporting leg upper strata to be spirally connected with the screw in middle supporting leg lower floor, also includes nut, and described nut is installed
For screw rod is spacing with arc-shaped through-hole on screw and positioned at middle supporting leg upper strata top.
Preferably, described middle supporting leg upper strata is provided with anti-skid wearable layer.
The beneficial effects of the utility model are: by being provided with arc-shaped through-hole on middle supporting leg upper strata, described middle supporting leg lower floor
On the screw set up, still can arbitrarily rotate when not needing spacing, when needing spacing, screw rod be passed through arc-shaped through-hole and spiral shell
Hole is spirally connected, then by nut, thus reaching, middle supporting leg upper strata is limited the effect rotating with nut extruding, can also control simultaneously
The angle rotating, substantially increases the using effect of rotatable middle supporting leg, and structure is simple and strong applicability.
Brief description
Fig. 1 is a kind of main structure diagram of the present utility model；
Fig. 2 is a kind of overlooking the structure diagram of the present utility model；
Brief description: 1, middle supporting leg upper strata, 2, middle supporting leg lower floor, 3, rotary flange, 4, screw rod, 5, screw, 6, arc leads to
Hole, 7, nut.
Specific embodiment
Below by embodiment, and combine accompanying drawing, the technical solution of the utility model is described in further detail.
Embodiment: as shown in Figure 1 to Figure 2, a kind of rotatable middle supporting leg, including in supporting leg upper strata 1, on described middle supporting leg
The lower section of layer 1 is provided with middle supporting leg lower floor 2, forms a double-layer structure；Set between described middle supporting leg upper strata 1 and middle supporting leg lower floor 2
There is rotary flange 3, the upper and lower ends of described rotary flange 3 are connected with middle supporting leg upper strata 1 and middle supporting leg lower floor 2 respectively, also include
Screw rod 4, described middle supporting leg lower floor 2 is provided with screw 5, and described middle supporting leg upper strata 1 is provided with arc-shaped through-hole 6, and described screw rod 4 passes through
Arc-shaped through-hole 6 on middle supporting leg upper strata 1 is spirally connected with the screw 5 in middle supporting leg lower floor 2, also includes nut 7, and described nut 7 is installed
And being used for positioned at middle supporting leg upper strata 1 top on screw 5 will be spacing with arc-shaped through-hole 6 for screw rod 4；Described middle supporting leg upper strata 1 is provided with
Anti-skid wearable layer.
By arc-shaped through-hole, the screw that described middle supporting leg lower floor sets up are provided with middle supporting leg upper strata, do not needing to limit
Still can arbitrarily rotate during position, when needing spacing, screw rod is spirally connected with screw through arc-shaped through-hole, then by nut general
Lower limb upper strata limits, thus reaching, the effect rotating with nut extruding, can also control the angle of rotation, substantially increasing can simultaneously
The using effect of the middle supporting leg of rotation, structure is simple and strong applicability.
Finally it is pointed out that above example is only the more representational example of this utility model.Obviously, this practicality is new
Type is not limited to above-described embodiment, can also have many deformation.Every according to technical spirit of the present utility model to above example
Any simple modification, equivalent variations and the modification made, is all considered as belonging to protection domain of the present utility model.
