Abstract
This utility model relates to a kind of rotatable middle supporting leg, and including middle 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；It is provided with rotary flange between described middle supporting leg upper strata and middle supporting leg lower floor, the two ends up and down of described rotary flange are connected with middle supporting leg upper strata and middle supporting leg lower floor respectively, also include positioning bar, being equipped with hole, multiple location on described middle supporting leg upper strata and middle supporting leg lower floor, described location bar is arranged on middle supporting leg upper strata and is each passed through middle supporting leg upper strata and the hole, location of middle supporting leg lower floor；By the hole, location set up on middle supporting leg upper strata and middle supporting leg lower floor, thus reach to limit the effect rotated through hole, location by location bar simultaneously, can also control the angle rotated simultaneously, substantially increase the using effect of rotatable middle supporting leg, simple in construction and the suitability are strong.
Description
Technical field
This utility model relates to a kind of rotatable middle supporting leg.
Background technology
Currently, Bridge Erector use working environment become increasingly complex, construction want condition for peace the most different, erection
During sharp radius curve bridge, the curved bridge that particularly span is bigger, Bridge Erector is limited by self huge body, often cannot be fitted
Should, will greatly affect the progress of construction, and due to the artificial angle exerted a force and the unstability of force direction, too increase and execute
The difficulty of work and danger coefficient.
Chinese patent CN202247701U discloses a kind of rotatable middle supporting leg at present, including middle 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 two ends up and down of described rotary flange are connected with middle supporting leg upper strata and middle supporting leg lower floor respectively.
Find through practice, though directly using rotary flange to solve the problem of rotation, in use can be convenient,
But rotation is limited and positions by unrestricted mechanism, will also result in difficulty and the danger coefficient of construction on the contrary.
Summary of the invention
The purpose of this utility model is to solve in prior art the defect existing for rotatable middle supporting leg, it is provided that one
Plant the rotatable middle supporting leg that rotation can be positioned and limits.
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 two ends up and down of described rotary flange respectively with middle supporting leg upper strata and middle supporting leg lower floor
Connecting, also include positioning bar, described middle supporting leg upper strata and middle supporting leg lower floor are equipped with hole, multiple location, described location bar is installed
Supporting leg upper strata and the hole, location of middle supporting leg lower floor on middle supporting leg upper strata and in being each passed through.
As preferably, described location bar includes the body of rod and head, and the cross section of the described body of rod is identical with location hole size, institute
State the cross section of head more than location hole size.
The beneficial effects of the utility model are: by the hole, location set up on middle supporting leg upper strata and middle supporting leg lower floor, with
Time through hole, location thus reach to limit the effect rotated by location bar, the angle rotated can also be controlled simultaneously, significantly carry
The high using effect of rotatable middle supporting leg, simple in construction and the suitability are strong.
Accompanying drawing explanation
Fig. 1 is one of the present utility model main TV structure schematic diagram；
Fig. 2 is a kind of plan structure schematic diagram of the present utility model；
Fig. 3 is a kind of structural representation in hole, this utility model location.
In figure, 1, middle supporting leg upper strata, 2, middle supporting leg lower floor, 3, rotary flange, 4, location bar, 5, hole, location, 6, the body of rod, 7,
Head.
Detailed description of the invention
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 3, a kind of rotatable middle supporting leg, including middle 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
Rotary flange 3, the two ends up and down of described rotary flange 3 is had to be connected with middle supporting leg upper strata 1 and middle supporting leg lower floor 2 respectively, also include
Location bar 4, described middle supporting leg upper strata 1 and middle supporting leg lower floor 2 are equipped with hole, multiple location 5, and described location bar 4 props up in being arranged on
On lower limb upper strata 1 and be each passed through middle supporting leg upper strata 1 and the hole, location 5 of middle supporting leg lower floor 2；Described location bar 4 includes the body of rod 6 and bar
7, the cross section of the described body of rod 6 is identical with hole 5, location size, and the cross section of described head 7 is more than hole 5, location size.
By the hole, location set up on middle supporting leg upper strata and middle supporting leg lower floor, simultaneously by location bar through location hole from
And reach to limit the effect rotated, the angle rotated can also be controlled simultaneously, substantially increase the use of rotatable middle supporting leg
Effect, simple in construction and the suitability are strong.
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, it is also possible to 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.
