Description
Technical field
The utility model is related to electrified apparatus field, specifically refers to a kind of modern tram contact net pendant top built-in
Compensation device.
Background technology
Modern tram is different from traditional tramcar, represents Modern Traffic development trend, can make up in city
Neutral gear between Rail Transit System and regular public traffic system, the part as the key public traffic network in city.It is modern
Tramcar is in urban economy, the region of population concentration, and the attractive in appearance, practical of its contact net, security performance are strictly prepared for the postgraduate qualifying examination,
Under this trend, the pendant built-in compensation device of top arisen at the historic moment is as the compensating mechanism of contact net for substituting existing tramcar
New structure, the security performance with more compact construction profile and Geng Gao.
And existing built-in contact net compensation device is all that falling mound string is built into anchor post, so that the occupation of land face of reduction
Product, but because pendant top string lifting activity in anchor post, the lifting of influence pendant top string can be contacted with anchor post inwall, or even cause anchor
Rod structure is damaged；Built-in falling mound string is general only in side provided with a shaft-like guide device, it is impossible to provide preferable
The spacing effect for preventing falling mound string from being rotated around axial line；And it is logical that long strip type can be offered on general built-in anchor post outer wall
Hole, its structural strength just decreases, once running into exceedingly odious weather, high wind blows contact net, so as to cause at two ends
Force compensating device load is aggravated, it is possible to which anchor post fracture occur causes the problem of whole contact net is paralysed.
Utility model content
For the defect of above prior art, the utility model provides one kind, and there is a kind of stabilizing mechanism to fall top string to stablize
Stable in support column it can lift, additionally it is possible to prevent falling mound string is significantly reversed from causing steel strand wires to take turns rubbing crack with chaste tree
The problem of occur modern tram contact net pendant the built-in compensation device of top.
The utility model is achieved through the following technical solutions：A kind of built-in compensation dress of modern tram contact net pendant top
Put, include provided with pendant top string in the support column of hollow structure, the support column, support column top is provided with the cunning connect with pendant top series winding
Wheel compensating device, the pendant top string includes the pendant top that two or more are socketed in same root connecting rod, the connecting rod two
End is equipped with the fixed disk for clamping pendant top, and the fixed disk both sides are symmetrically arranged with the projection vertical with connecting rod, described
Projection is provided with pulley, and support column wall is provided with the sliding rail for being used for guiding the string lifting of pendant top with pulley cooperation.
Principle of the present utility model：The utility model is a kind of compensation device of contact net, is by contact line two ends
Carry out tensioning so that contact line can keep tensioning state provided with the pendant top with constant weight, thus avoid contact with line because across
Degree is larger and is influenceed to fall downwards by self gravitation.And it is identical in the structure that two ends are set, it is the support column of same size, it is described
Support column can for cylinder or rectangular cross-section long strip type structure, do not limit specifically.But support column is closing
Formula structure, is provided with air-vent, it is to avoid the perforate on support column shaft is so as to influence its structural strength in support column bottom.And support
The sliding rail that pillar height degree is not higher than inside 6m, support column has two, is symmetricly set on support column wall, the length of sliding rail
Degree and setting height(from bottom) are based on live actual demand, and the peak of sliding rail is not higher than 4.5m, and the minimum point of sliding rail is not
Less than 0.8m.And the peak of falling mound string is not higher than 4.3m, minimum point is not less than 1m, and sliding rail can limit pendant top string, one
Denier steel strand wires are broken, and when pendant top string loses external pull and fallen downwards, described sliding rail bottom can stop falling mound
Bottom go here and there to whereabouts.Contrasted by many experiments, 20 composition falling mound strings are being provided with standard pendant top weight 25kg, pendant is allowed
Stone roller string falls downwards from 4.5m maximum height, is now the height for the maximum thrust that sliding rail bottom can bear falling mound string
Degree, so the maximum height of falling mound string is set into 4.3m, to provide 0.2m protection value.
Described projection is extended into sliding rail and carried out in roller of the projection end provided with multiple different directions
The structure of spacing slip, projection is rectangular shape, and its end face is provided with and the roller perpendicular to sliding rail, the top of projection
Towards the side on support column top when side is installed for fixed disk, and the lower side of projection is relative with upper side, and convex
The side of left and right two of block is provided with roller close to sliding rail side, the roller on the fixed disk two ends projection end face by with
Sliding rail is contacted, and can be limited falling mound string and be kept stable on a horizontal line；And be provided with two sides of projection or so
Roller can anti-falling stop top string around axial line twist so that pendant top be merely able to move vertically up and down along the center line in support column
It is dynamic.And described pulley compensating device is for connection to the structure of contact line and falling mound string, become by pulley compensating device
To the gravity on the vertical direction of falling mound string being changed into the pulling force in horizontal direction, so as to keep the tensioning state of contact line.
Preferably to realize the utility model, further, the support column includes the upper prop connected by flange with
Post, the upper prop side is provided with opening, and the pulley compensating device is arranged in opening and is fixed on column wall.Once mend
Repay and gone wrong inside device when needing maintenance, it is necessary to whole support column is pulled down and overhauled, and after long-time use, it is described
The junction on support column and ground is it is possible that the situation that Nian Jie or crimp can not be dismantled normally, so as to be merely able to brokenly
Bad property is removed.Once support column arrangement is destroyed or cement base is destroyed, it is necessary to is re-replaced or is poured into a mould, increase is not
Necessary cost；Described upper prop can be dismantled, so as to change the connection status of support column base and ground
In the case of can carry out inspection and maintenance to the falling mound string in support column or other structures there is provided preferable convenience and economy
Property.And pulley compensating device, which is arranged at the opening of upper prop, can further increase of the present utility model compact.
Further, the pulley compensating device includes being hinged with the bearing being fixed on column wall, the bearing
