Technical field

The present invention relates to a kind of bridge sling anchorage pin shaft refueling device and its oiling methods, belong to bridge maintenance technology neck Domain.

Background technique

Sling of suspension bridge is connect by the fork ear of anchorage lower end with pin shaft with bridge anchor tie plate, and steel box-girder is connect with main push-towing rope Together, become one of the important stress node of bridge superstructure.After being open to traffic, automobile will cause bridge when passing through bridge Steel box-girder vibrates up and down, and pin shaft is caused to generate fine rotation in the axis hole of fork ear, when bridge is installed, between pin shaft and axis hole Oil has been added to be lubricated, the lubricating oil after a period of time that is open to traffic in axis hole can be depleted, pitches ear at this time and the opposite of pin shaft turns Dynamic to wear pin shaft and axis hole, pin shaft can be levigate over time, influences bearing capacity, and pin shaft is needed replacing when serious, time-consuming Arduously.

Some bridges attempt the lubricating status for improving pin shaft by way of adding lubricating oil in maintenance, but due to pin shaft With the design gaps very little of axis hole, seldom, also lubricating oil can not be allowed to reach in entire axis hole using common oiling mode oil inlet quantity Between, it can not effectively solve the lubrication problem of pin shaft.Domestic a large amount of suspension bridge is using the design of this pin shaft at present, it is oily at For a great problem for perplexing bridge inspection and maintenance.

Summary of the invention

The technical problem to be solved by the present invention is to provide a kind of bridge sling anchorage pin shaft for the above-mentioned prior art to add Oily device and its oiling method, it can effectively ensure that the oil inlet quantity of anchorage pin shaft, and lubricating oil can be made to reach among axis hole, from And improve the lubricating status of pin shaft, the service life of pin shaft is effectively increased, reduces the maintenance of bridge sling anchorage pin shaft more Change this into.

The present invention solves the above problems used technical solution are as follows: a kind of bridge sling anchorage pin shaft refueling device, it Including hermetically sealed can, the hermetically sealed can back-end closure front opening is emptied to form round shoe cream room inside the hermetically sealed can open end, The circle shoe cream room internal diameter is greater than anchorage pin diameter, and hermetically sealed can closed end center is coated with fastening bolt, described tight Fixing bolt front end is protruded into round shoe cream room after passing through hermetically sealed can closed end, and the fastening bolt front end is provided with magnetic force mechanism, The magnetic force mechanism includes permanent magnet, is provided with built-in nut on the permanent magnet rear end face, the fastening bolt front end with it is interior It sets nut to be connected, the permanent magnet diameter is less than anchorage pin diameter, and the hermetically sealed can is distinguished at periphery wall relative position It offers the first mounting hole and the second mounting hole, connects plastics oil filling pipe at first mounting hole, at second mounting hole It is provided with fuel outlet valve, the hermetically sealed can open end is provided with annular sealing strip on end face.

Preferably, the hermetically sealed can is adopted made of plastic.

Preferably, the hermetically sealed can is at cylindrical or polyhedron column construction.

Preferably, gasket and sealing ring are set in the fastening bolt, the gasket and sealing ring are set to fastening spiral shell Between bolt and hermetically sealed can.

It is processed into hole shape in the preferred fastening bolt rear end.

A kind of oiling method of bridge sling anchorage pin shaft refueling device, the described method comprises the following steps:

Step 1: the deposit between the anchorage pin shaft surface that needs are refueled, fork ear side and pin shaft and pin shaft hole is cleared up Completely；

Step 2: magnetic is in place after the permanent magnet of refueling device is directed at anchorage pin shaft center, adjustment hermetically sealed can position makes Fastening bolt is vertical with magnet, and make plastics oil filling pipe above, fuel outlet valve it is below, gradually lock fastening bolt until annular Sealing strip generates obvious become；

Step 3: fuel outlet valve is closed, add lubricating oil into hermetically sealed can from plastics oil filling pipe, until full of entire sealing Tank simultaneously makes the oil level in plastics oil filling pipe reach 30cm or more；Kept for a period of time, until oil level decline reaches in plastics oil filling pipe When to specified altitude, fuel outlet valve is opened, remaining lubricating oil in hermetically sealed can is released, terminates this refueling operation.

Preferably, the specified altitude that oil level decline reaches in step 3 is 5~20cm.

Compared with the prior art, the advantages of the present invention are as follows:

A kind of bridge sling anchorage pin shaft refueling device of the present invention and its oiling method, it can effectively ensure that anchorage pin shaft Oil inlet quantity, and can make lubricating oil reach axis hole among, so as to improve the lubricating status of pin shaft, effectively increase the use of pin shaft Service life reduces the maintenance replacement cost of bridge sling anchorage pin shaft.
