Description
Technical field
The present invention relates to a kind of cable expansion compensation arrangement, particularly a kind of gap bridge cable expansion compensation arrangement.
Background technology
The residing environment temperature of bridge with and the load external conditions such as an operation of getting on the bus, wind, earthquake, can make the railway carriage or compartment beam of bridge produce flexible and distortion, thereby make the cable on the bridge that is laid in also and then produce dilatation.If cable flexible do not absorbed and compensate, cable will produce bending or bear excessive tension force because of excessive bending.The repeated multiple times generation of this situation will cause the cable fracture.Therefore need to compensate the flexible of cable, the compensation of adopting is at present mainly adopted snake laying stretching with the reply bridge with cable at bridge, its specific practice is: adopt large horizontal snake laying in the middle of the bridge, install on the bridge expanssion joint both sides and be used for the device of flexible compensation of absorbing cable telescopic variation.But adopt horizontal snake laying compensation, compensation rate is limited on the one hand, railway carriage or compartment beam because of bridge is not only producing flexible and distortion along the pontic horizontal direction on the other hand, and can make dislocation or the knuckle that produces vertical direction between the beam railway carriage or compartment, so level compensating fundamentally solves the cable expansion problem; Simultaneously, that existing gap bridge power cable expansion compensation device is installed is comparatively complicated, it is larger to take the bridge installing space, and difficulty is larger during the cable laying construction.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, can carry out comprehensive compensation, simple in structure a kind of gap bridge cable expansion compensation arrangement to cable expansion and provide a kind of.
A kind of gap bridge cable expansion compensation arrangement, including two parts consists of, consisted of by the fixed part and the movable part that are divided into bridge seam both sides, described fixed part includes support, described movable part includes the track of the interval series splicing more than a section, described track is spaced double track, include the coaster more than an one, coaster supports in orbit successively and moves reciprocatingly along track, the parallelogram four-bar mechanism of the even number set that is arranged in order before and after described movable part also includes, the parallelogram four-bar mechanism of last group is arranged on the holder of rear portion, the parallel four limit row four-bar mechanisms of all the other groups are arranged on the coaster, the parallelogram four-bar mechanism of each group includes the consistent a pair of parallel four limit row four-bar mechanisms of motion of symmetric arrays, the plane of movement of parallelogram four-bar mechanism is along the trend of track, two side link in tandems of each parallel four limit row four-bar mechanism also are articulated in coaster or the same side of holder, the parallel four limit row four-bar mechanisms of even number set form a cover in twos, the motion that parallel four limit row four-bar mechanisms in every suit are done in opposite directions or deviated from mutually, parallel four limit row four-bar mechanisms, the two adjacent side links of group stretch out before and after in every suit, the extension of front and back group two symmetries is hinged on the same turning cylinder, described extension pin joint is higher than parallel four limit row four-bar mechanism connecting rods, described turning cylinder extends arrangement along the cross-sectional direction of track, described gap bridge cable expansion compensation arrangement also includes the cable hunting gear suitable with parallel four limit row four-bar mechanism group numbers, each cable hunting gear includes the fixed mount for the attached cable anchor clamps, this fixed mount is arranged along the track cross-section direction, on fixed mount, be provided with the fixing hole that is used for fixing a plurality of cable cleats of many groups along the place of trend of track cross-section, described fixed mount is arranged at the pin joint place that parallel four limit row four-bar mechanisms are not done side link and the connecting rod of extension, cable also is arranged on the coaster by cable cleat, be provided with dog-ear device between the fixed part of gap bridge cable expansion compensation arrangement and the movable part, one end of described dog-ear device is connected on the fixed part, and the other end then is connected with coaster on the movable part.
