Abstract
The utility model discloses a movable suspended type maintenance unit used for a base-supporting steel-truss bridge, and is especially used for the base-supporting steel-truss bridge of the electrified railway. The movable suspended type maintenance unit used for a base-supporting steel-truss bridge comprises a braced vehicle arranged on the upper part of the steel bridge, hanging cages suspended on both ends of the braced vehicle and used for maintaining braced girders on both sides of the steel bridge and an elevated bench used for maintaining the top bracing and the lateral bandage. In order to ensure the safe operation on the bridge beam of the electrified railway without the power failure, antielectricity equipment is arranged on the movable suspended type maintenance unit used for a base-supporting steel-truss bridge.
Description
The utility model is a kind of base-supporting steel truss girder bridge that is used for, especially for the movably suspension type maintenance unit of electrified railway base-supporting steel truss girder bridge.
The base-supporting steel truss girder bridge need during use regularly to full-bridge eliminate rust, maintenance activity such as japanning.What adopt usually is the method for maintaining that full bridge is set up scaffold, this method not only need be with a large amount of timber, and take because of segmentation and to tear scaffold open, also can expend a large amount of labours and time, especially on the steel bridge of electrified sections during operation, be 25 kilovolts contact system because of being hung with voltage on the bridge, for ensureing workman's job safety, contact system must have a power failure, and so not only carrying capacity is transported in influence, and is restricted because of power failure makes bridge maintaining work.
" truss bridge anti-power repairing vehicle " (Chinese patent ZL86200413.6) of Xi-an Science 7 Technology Inst., Zhengzhou Railway Burean's development solved the cancellation scaffold preferably and guaranteed the problem of workman's job safety, and reduced the interference of maintenance activity to the driving transportation, but because the restriction of this body structure of said apparatus, with the inboard of its maintenance base-supporting truss bridge and top bracing and sway bracing is feasible, and will still need set up scaffold with its outside of keeping in repair trusses.
The purpose of this utility model is that a kind of later-model truss bridge maintenance unit will be provided, and is used for keeping in repair the base-supporting truss bridge of non-electrified railway and electrified railway.Particularly in electrified railway, do not cut off the power supply, under the situation of the normal operation of train, can keep in repair the outside and the inboard and the top bracing of steel bridge truss easily and safely with it at contact system.When it is mobile on bridge, do not clash with the overhead contact line parts.
The utility model is to realize like this, on the main couple of steel bridge both sides horizontal one can be along the purlin car that main couple vertically moves, the outside of two main couples is stretched out at the two ends of purlin car, the outside at close steel bridge two main couples in the bottom at car two ends, purlin, hang installation with the cage form and hang bench board for two groups, hang the bench board in the vertical direction and divide several layers, every layer all has the part that puts in steel bridge main couple inboard.But the bench board of purlin car setting vertical lifting, and electric bonding is set below self-powered platform.
The utility model adopts component assembly to form, thereby installing/dismounting is convenient rapidly, in addition, because this device all is in the outside of bridge when installing and use, do not take space in the bridge, so just further reduced to the interference of driving a vehicle and with the conflicting of overhead contact line system.
The concrete structure of utility model is provided by the following drawings.

Describe concrete structure of the present invention and embodiment in detail below in conjunction with accompanying drawing.
The utility model device can be divided into three parts: purlin car (1), cage (2) and self-powered platform (3).
Purlin car (1) is the support component of whole device, is the truss structure that adopts the section bar rod member to be spliced.4 walking wheels are equipped with in the bottom of purlin car (1), and wherein two is active walking wheel (4), and two is servo-actuated walking wheel (5).The traveling of purlin car is to rotate with manpower or other power driven hinge wheel (8), and through chain (9) transmission, minor sprocket (10) rotates, and drive active walking wheel (4) rotation realizes.Brake gear is equipped with in top at two servo-actuated walking wheels (5), and it is made up of braking handwheel (11), leading screw (30) and brake shoe (12).Rotation hand wheel (11), leading screw (30) move up or down, and the brake shoe that the leading screw lower end connects just can compress or leave servo-actuated walking wheel (5), thereby play braking or mitigation.
Self-powered platform (3) is mainly used in the top bracing of steel bridge and the laterally maintenance of each rod member of connection rope.Self-powered platform (3) comprises one for people stand base plate (23), protection railing (24) and the all-insulated plate (29) of work.Protection railing (24) be trapped among base plate (23) around, the bottom of railing (24) and base plate (23) are hinged, railing can uprightly also can fall on base plate (23), and all-insulated plate is parallel to base plate (23) is fixed in base plate (23) with the insulation joint piece below.Self-powered platform (3) is fixed in the bottom of pilot bar (25), pilot bar (25) places in the barrel-contoured guide frame (26), one end of hauling rope (28) is fixed on the pilot bar (25), the other end is drawn by guide frame upper opening place and is fixed on the winch (27), the rising of self-powered platform or whereabouts are by rotating winch (27), folding and unfolding hauling rope (28) carries that pilot bar (25) realizes.
Cage (2) adopts the framed structure of section bar splicing.Cage (2) divides two groups of two ends that fixedly hang on purlin car (1) with connector (13).Every group of cage gone up lower link by a plurality of independent cages by connector (13) and formed, independently be provided with to stand or place base plate that facility use and constitute and hang work top (14) in the bottom of cage (2) at each for the people, on suspension work top (14), be provided with by hole (30), go up dress cover plate (15) by hole (30), one side of cover plate (15) is hinged with suspension work top (14), when the staff by by hole (30) by the time, cover plate (15) can be dug.Hang work top (14) at each and lean on a side of steel bridge main couple that drop in leaf (16) is set, turnover panel (16) is hinged with cage (2).Turnover panel (16) can be packed up, and is in vertical position; Can put down, be horizontal.When turnover panel (16) when being horizontal, the collapsible railing (31) that is arranged on the cage (2) can impale turnover panel (16), plays protective action.Turnover panel (16) is when being in vertical position, with the vertical rod member stationary positioned of latch with itself and cage (2), when turnover panel (16) when being horizontal, hang with chain sling (17), one end of chain sling (17) is fixed on the one side in turnover panel (16) outside, and the other end of chain sling (17) is fixed on the rod member of cage (2).In a side of cage (2), ladder (18) is climbed in the in the vertical direction setting, about the staff is in cage.In addition, when the staff up and down during cage (2) activity of setting up temporarily climb ladder (19).
Cage of the present utility model (2) and suspension work top (14) can have another scheme in force.The number of each group cage (2) is highly definite by maintenance, but after each group cage is fixedly connected up and down, fixing suspension work top (14) and turnover panel (16) are not set in the cage, but can in cage, replace by the bench board of vertical lifting with one, drop in leaf and self-powered platform one lifting also are set on the above-mentioned self-powered platform, the lifting of bench board and turnover panel is to realize by the winch and the hauling rope that are arranged on the car of purlin, one end of hauling rope is fixed on the winch, the other end is fixed on the bench board, when rotating winch, hauling rope can spur bench board and do dipping and heaving.
For making the traveling on bridge of this device, go up the laying removable rail that moves (6) at the upper cord member (7) of steel bridge both sides main couples (22), rail (6) is fixed with special jig and steel bridge.
