Background technology
Along with the continuous expansion of city size, the demand of the scale of city to power consumption increases rapidly, the harmony of urban planning and Electric Power Network Planning is increasingly important, overhead wire to civic landscape and and the impact that causes of space more and more obvious, for making city attractive in appearance and realize the reasonable utilization of urban space, also for ensureing the needs of all kinds of facilities and personal safety, transmission line of electricity takes cable laying to become important measures in Electric Power Network Planning simultaneously.And high voltage power cable is passed a bridge as a kind of situation in cable laying.In the time that cable passes through river, sea, lake, water-bed cabling is more complicated, and interruption of service is higher, and using cable gap bridge technology to solve cable laying problem is that current electrical network is planned one of method adopting, cable laying, in the bridge case of bridge, can be saved to the spending of cable laying passage greatly.But because the hot telescopicing performance of bridge and cable differs greatly, therefore, in the time of the installation of high voltage power cable gap bridge, must consider the flexible absorption of bridge, especially bridge stroke is larger, adopts snake laying cannot absorb the flexible of bridge at all.
Utility model content
The purpose of this utility model is that providing a kind of for the deficiencies in the prior art is easily installed in gap bridge cable on bridge, and the cable that makes to pass a bridge can change with the variation of bridge expanssion joint, prevent that bridge stroke from causing more greatly the gap bridge cable expansion that fractures or the break seam compensation arrangement of cable.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of gap bridge cable expansion seam compensation arrangement, comprise underframe, linkage, steel spring plate, holder clip wheel and fastening clip for cable, described underframe comprises the first separate underframe and the second underframe, described the first underframe and the second underframe are separately fixed at the both sides of bridge expanssion joint, ultimate range between described the first underframe and the second underframe near-end is greater than the distance of bridge expanssion joint, the two ends of described linkage are hinged on respectively on described the first underframe and the second underframe, described the first underframe and the second underframe are provided with described fastening clip for cable, described fastening clip for cable is fixed the two ends of cable, the middle part of described cable is fixed on described linkage by fastening clip for cable.
One end of described the first underframe is fixed on a side of bridge expanssion joint, and the other end is arranged on the opposite side of bridge expanssion joint and is supported on the slip blade on bridge.
Described linkage is formed by two rod hinge connections, described in two, on the pin joint of connecting rod, be fixed with the steel spring plate that length is extended along the direction of cable, described steel spring plate is arranged on the end that cable described in the supported underneath of described cable and described steel spring plate extend and is provided with the fixing described cable of described fastening clip for cable.
On connecting rod near bridge expanssion joint one end in described linkage, the first clip wheel is installed, described cable rolls and is connected with described the first clip wheel.
Between described the first underframe and described the second underframe, the guide link mechanism coordinating with described linkage is also installed, described guide link mechanism two ends are hinged on respectively on described the first underframe and the second underframe, and the described cable stretching out from described linkage rolls and is connected with described guide link mechanism by being fixed on the second clip wheel described guide link mechanism.
Described guide link mechanism is formed by two rod hinge connections, described guide link mechanism is fixed with steel spring plate at the pin joint of connecting rod described in two, and described steel spring plate is arranged on end that cable described in the supported underneath of described cable and described steel spring plate extend and is provided with support roller and supports described cable.
Owing to adopting said structure, the utility model is by the fixed frame respectively of the both sides at bridge expanssion joint, and by fastening clip for cable, cable is fixed on to the both sides at shrinkage joint, the middle part of cable is by being arranged on the linkage support and connection between two underframe, thereby make the deformation path of cable in the time that bridge is flexible controlled, in the time that bridge is flexible, the movable end of linkage moves up and down along with the variation of bridge expanssion joint distance, drive cable to move in vertical direction, just offset cable due to the bridge expanssion joint amount of elongating or shortening in the horizontal direction, and by the support of the steel spring plate on linkage and guide link mechanism upper spring steel plate, make the radian in cable deformation knee large, prevent that cable from producing fatigue effect, cause fracture, and by the clip wheel on guide link mechanism and linkage, ensure that cable can move along the direction of motion of linkage, prevent sideslip, one end of the first underframe is fixed on a side of bridge expanssion joint, the other end be arranged on the opposite side of bridge expanssion joint and with the slip blade being supported on bridge on, arrange is like this because be generally the position of Bridge Beam in the position at bridge expanssion joint place, the height of general this position is because beam has occupied certain altitude, in order to prevent that linkage from being hindered in the time moving, therefore extend linkage is arranged on to the side that bridge inner space is openr by the first underframe, this device is adapted to wider.
