It does not depart from, and the level load of contact line is transmitted to pillar.Pillar and basis are to bear contact suspension, support and positioning device
Whole loads, and it is contact suspension is fixed in defined position and in height.It is mixed using deformed bar in Chinese contact net
Solidifying soil pillar and steel column, basis are for steel strut, i.e., steel strut is fixed on basis made of following armored concrete
On, whole loads that pillar is transmitted to are born by basis, and guarantee the stability of pillar.Prestressed reinforced concrete pillar and basis
An entirety is made, lower end is directly embedded to underground.
In the operation of contact net, it often will appear at certain parts and water leakage situation occur, if do not detected in time
And components are replaced, serious security threat is generated to contact net.Therefore periodically to carry out contact net and make an inspection tour work.Staff
Periodically to check the appearance of contact net whether have leak above inspection contact net and count the leak above anchor point
Leak serious conditions and position above point, statistics busbar connector, are all to use these manually recorded situations of staff at present, not side
Just and to work belt carry out additional workload.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the deficiencies of existing technologies, provide it is a kind of convenient for operation can hand
Hold leakage inspector.
