Abstract
The utility model relates to a vertical suspension adjustable hanging column. A traditional hanging column mounting structure of a contact net in subway tunnels can not be adjusted in the direction of vertical height, and can not be suitable for sink activity of tunnel structures. The vertical suspension adjustable hanging column comprises a hanging column and two outwardly leaned connecting arms, wherein the hanging column is welded by a hanging column bottom plate and an I-shaped pipe, two columns of bolt holes are arranged on the two sides of the I-shaped pipe, the connecting arm on one side comprises a connecting steel channel, a bottom end connecting plate and a top end connecting base plate which are welded, the connecting base plates on each side and the I-shaped pipe are fixed through two flange bolts, and the connecting plates and rigid suspension contact lines are fixed through hexagonal head bolts. the vertical suspension adjustable hanging column can coarsely adjust suspension height of the contact lines by adjusting fixed height of the connecting arms on the hanging column, and also can finely adjust the suspension height of the contact lines by rotating the nuts arranged on the hexagonal head bolts of the connecting plates, thereby meeting the requirements that conduction height of the contact net is upwardly adjusted after tunnels sink and change on the whole, and reducing operation and maintenance workload.
Description
Technical field
the utility model belongs to electric railway and urban rail transit contact network technical field, is specifically related to a kind of capable of regulating hanging column of vertical hanging.
Background technology
Existing hanging column, particularly application is limit hanging column with the height of the interior contact system of subway tunnel, normally by bottom pre-embedded bolt or after bury anchor and fasten and be fixed on concrete support face, its underpart is connected with erecting equipment by bolt assembly, thereby complete, the hanging column of erecting equipment is installed.Tradition hanging column mounting structure cannot regulate in vertical dimension direction, cannot adapt to the sinking activity of tunnel structure, changes the hanging column that length differs, and has increased cost, is also unfavorable for actual use.
Summary of the invention
The purpose of this utility model is to provide a kind of capable of regulating hanging column of vertical hanging, limits the connection channel-section steel of hanging column to be designed to upper and lower all adjustable packaged type forms height, to meet after the whole sinking in tunnel changes, contact system is led to the needs that height adjusts upward.
The technical scheme that the utility model adopts is:
A capable of regulating hanging column for vertical hanging, is characterized in that:
Include two outward-dipping connecting arms of hanging column and hanging column both sides;
Hanging column is welded to form to vertical I-shape pipe by square tube under the hanging column base plate of top level and hanging column base plate, on hanging column base plate, be provided with for self fixing bolt hole, I-shape pipe both sides be all provided with from top to bottom two row for the fixing bolt hole of connecting arm;
Every side connecting arm is welded to form by the connecting panel connection backing plate vertical with being connected channel-section steel top of outward-dipping connection channel-section steel, connection channel-section steel bottom level, on connecting panel, be provided with for self fixing bolt hole, on connection backing plate, be provided with for the fixing bolt hole of I-shape pipe;
The connection backing plate of every side and I-shape pipe fix by two bolt with flanges; Connecting panel fixes by hex bolt and rigid suspended contact wire.
The utlity model has following advantage:
The utility model adopts bolt with flange form to connect hanging column and connecting arm, is designed to the packaged type form of upper and lower adjusting setting height(from bottom), to meet after the whole sinking in tunnel changes, contact system is led to the needs that height adjusts upward; Adopt hex bolt, by hex bolt, to leading height, run business into particular one and when inching is led High variation to meet, adjust needs.Reduced operation maintenance work capacity, improved operation security reliability, simple installation, superior performance, economical rationality.

Fig. 3 is the utility model birds-eye view.
In figure, 1-hanging column, 2-connecting arm, 3-I-shape pipe, 4-hanging column base plate, 5-connects channel-section steel, 6-connecting panel, 7-connection backing plate.
The specific embodiment
Below in conjunction with the specific embodiment, the utility model is described in detail.
The capable of regulating hanging column of a kind of vertical hanging that the utility model is related, includes two outward-dipping connecting arms 2 of hanging column 1 and hanging column 1 both sides.Hanging column 1 is welded to form to vertical I-shape pipe 3 by hanging column base plate 4 and 4 times square tubes of hanging column base plate of top level, on hanging column base plate 4, be provided with for self fixing bolt hole, I-shape pipe 3 both sides be all provided with from top to bottom two row for the fixing bolt hole of connecting arm 2.Every side connecting arm 2 is welded to form by connecting panel 6 connection backing plate 7 vertical with being connected channel-section steel 5 tops of outward-dipping connection channel-section steel 5, connection channel-section steel 5 bottom levels, on connecting panel 6, be provided with for self fixing bolt hole, on connection backing plate 7, be provided with for the fixing bolt hole of I-shape pipe 3.Connection backing plate 7 and the I-shape pipe 3 of every side fix by two bolt with flanges; Connecting panel 6 fixes by hex bolt and rigid suspended contact wire.
During use, first by adjusting the suspension height of the standing height coarse adjustment contact wire of connecting arm on hanging column, by the nut of turn connecting panel place hex bolt, the suspension height of contact wire is finely tuned again, make rigid suspended contact wire suspension height meet the requirement for height of contact system planar design completely.
It is cited that content of the present utility model is not limited to embodiment, and the conversion of any equivalence that those of ordinary skills take technical solutions of the utility model by reading the utility model specification sheets, is claim of the present utility model and contains.
