Description
Technical Field
The utility model relates to a contact net equipment technical field especially relates to an earring formula hangs base.
Background
An overhead rigid suspension bus power supply system is an important power supply mode of an urban rail transit contact network. The rigid suspension system is installed at the top of the circular tunnel in two ways at present, one way is that expansion bolts are temporarily punched and installed on a construction site to be fixedly installed; the other type is that the mechanical conversion installation is realized by the matching suspension base of the embedded channel. The expansion bolts are adopted to be installed on site, the workload is large, the installation reliability is low, and the expansion bolts are gradually replaced by the installation mode of the hanging base matched with the embedded channel.
The traditional suspension base is relatively fixed at the installation position of the tunnel top, because of reasons such as construction installation errors and the like and when a larger contact line pull-out value is adjusted, the installation position of the conversion base for the embedded channel is often required to be moved, after the installation position is adjusted, a suspension bolt does not need a plumb, installation can be ensured only by selecting and matching inclined washers of different specifications, the workload of selecting and matching the installation inclined washers is large, the suspension bolt does not meet the current design requirement even if the plumb does not meet the current design requirement, after the conversion base for the traditional embedded channel is stressed along the direction of the line, the stress condition of the embedded channel is poor, and the construction and installation requirements of parts of a rigid suspension system which is higher and higher cannot be met.

The utility model aims at providing an earring type suspension base, which comprises a body, wherein the body is a symmetrical integrated structure, the bottom surface of the body is a continuous smooth curve structure and is symmetrically distributed, the central line of the bottom surface on the body is provided with lugs distributed at intervals, the horizontal heights of the lugs are on the same horizontal line, the heights of the lugs are gradually reduced from outside to inside, and fixing holes are arranged between the lugs;
the top surface of body includes that connecting portion and symmetric distribution are in the installation department of connecting portion both sides, the both sides of connecting portion below are equipped with the hangers of symmetric distribution, the below of hangers is equipped with the connecting hole.
Preferably, the length of the projection on the outer side is smaller than the length of the projection on the inner side.
Preferably, the bottom surface of the body is of a nearly tetragonal structure.
Preferably, the outer edge of the middle part of the hanging lug is provided with a triangular reinforcing rib connected with the bottom surface of the body.
Therefore, the utility model adopts the above structure an earring formula hangs base, simple structure, the installation of being convenient for.
