Description
Technical field
The utility model relates to support column field, and specifically a kind of winding stair formula supports fore-set.
Background technology
At present, in flight-line maintenance, in fabrication and installation and equipment repair process, often need jack workpiece or equipment jack-up to be come, also need other back-up blocks (plate, post) supplemental support to live other some positions in workpiece or equipment simultaneously.The height come owing to needing jack-up is different, is sometimes difficult to the back-up block (plate, post) finding height dimension suitable, causes some troubles to work.
Utility model content
The purpose of this utility model is to provide a kind of winding stair formula to support fore-set, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of winding stair formula supports fore-set, comprise backspin annulated column ladder block, upper disk pressure head, center guide pillar, lower disc wedge and on revolve annulated column ladder block, described upper disk pressure head and lower disc wedge are discoid, and upper disk pressure head and lower disc wedge are equipped with centre bore; The below of described upper disk pressure head is fixedly connected with backspin annulated column ladder block, lower disc wedge be provided with backspin annulated column ladder block agree with mutually on revolve annulated column ladder block, and on revolve annulated column ladder block be fixedly connected with lower disc wedge, described center guide pillar is fixed in the centre bore of lower disc wedge, and the other end of center guide pillar extends in the centre bore of disk pressure head; The center of revolving annulated column ladder block and backspin annulated column ladder block on described is equipped with the cylindrical channel matched with center guide pillar.
As further program of the utility model: described backspin annulated column ladder block, upper disk pressure head, center guide pillar, lower disc wedge and on revolve annulated column ladder block and adopt stainless steel to make.
As the utility model further scheme: the diameter of described upper disk pressure head and lower disc wedge is 500cm-1800cm.
As the utility model further scheme: the diameter of described center guide pillar is 50cm-100cm.
Compared with prior art, the beneficial effects of the utility model are: this project organization of the utility model is simple and reliable, as required, this winding stair formula can be adopted to support fore-set, easily size can be adjusted to proper height, save time, increase work efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation that a kind of winding stair formula of the utility model supports fore-set.
In figure: 1-backspin annulated column ladder block, the upper disk pressure head of 2-, 3-center guide pillar, 4-lower disc wedge, 5-revolve annulated column ladder block.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, in the utility model embodiment, a kind of winding stair formula supports fore-set, comprise backspin annulated column ladder block 1, upper disk pressure head 2, center guide pillar 3, lower disc wedge 4 and on revolve annulated column ladder block 5, described upper disk pressure head 2 and lower disc wedge 4 are discoid, and upper disk pressure head 2 and lower disc wedge 4 are equipped with centre bore; The below of described upper disk pressure head 2 is fixedly connected with backspin annulated column ladder block 1, lower disc wedge 4 be provided with backspin annulated column ladder block 1 agree with mutually on revolve annulated column ladder block 5, and on revolve annulated column ladder block 5 be fixedly connected with lower disc wedge 4, described center guide pillar 3 is fixed in the centre bore of lower disc wedge 4, and the other end of center guide pillar 3 extends in the centre bore of disk pressure head 2; Revolve annulated column ladder block 5 on described and be equipped with the center of backspin annulated column ladder block 1 cylindrical channel matched with center guide pillar 3.
Described backspin annulated column ladder block 1, upper disk pressure head 2, center guide pillar 3, lower disc wedge 4 and on revolve annulated column ladder block 5 and adopt stainless steel to make.
Described upper disk pressure head 2 is 500cm-1800cm with the diameter of lower disc wedge 4.
The diameter of described center guide pillar 3 is 50cm-100cm.
Operation principle of the present utility model is: during work as required, upper disk pressure head 2 and lower disc wedge 4 are pulled open certain distance, opposite direction rotating under center guide pillar 3 acts on, under the height needed, make to revolve annulated column ladder block 5 be interlocked with backspin annulated column ladder block 1 simultaneously, as highly improper in regulated, can proceed to regulate by mode above, until complete.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this description is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of description is only for clarity sake, those skilled in the art should by description integrally, and the technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
