Abstract
The utility model relates to a sliding system used in a cable expansion arc, which comprises a sliding track, a sliding base plate and a support fixing seat, wherein the sliding track is erected on an expansion arc base seat; the two ends of the sliding base plate are respectively erected on the sliding track; and the support fixing seat is arranged on the sliding base plate. Compared with the prior art, the sliding system has the advantages of simple structure and fastness for support, cables can be well fixed and installed on a bridge and can slide according to the condition of thermal expansion and cold contraction, unfavorable influences on the cables by expansion and fold angle changes are reduced in a maximal degree, and the service life of the cables is prolonged.
Description
Technical field
The utility model relates to a kind of cable connecting arrangement, especially relates to a kind of sliding system that is used in the flexible arc of cable.
Background technique
Along with the development of regional economy and the refinement of zone location, domestic development and use to offshore island day by day heat up, pay attention to further in recent years.A plurality of islands, the whole nation have been warded off is shipbuilding base, generating base, combustion gas terminal, port and pier etc., wherein is no lack of the Changxing Island in Shanghai shipbuilding base is arranged, island harbour mouth base, mountain, small ocean etc.Establish and solve long-term goods and materials transportation problem for what cooperate these bases, local government is also often glad to build bridge to connect all islands and continent.This just provides a kind of new way for solving the long-term electric power transportation problem of scratching the island that is stranded.
220kV Chongming networking project is laid 2 go back tos 220kV cable run to 220kV Chen Jia towns of Chongming Island and is stood from station, sea, 220kV continent, and cut-offs the station of encircling to go into to be positioned on the Changxing Island, 220kV Changxing.By detailed investigation, analysis, comparison, engineering determines to adopt the Shanghai Chong Su major path route scheme of building, pass through basin for shipping, south, the Changjiang river with tunnel style, cross over basin for shipping, north, the Changjiang river in the bridge mode, the about 37km of all fronts length, being maximum in the world at present bridge tunel engineering, also is simultaneously that the power cable of the domestic the first 220kV electric pressure of China is striden the bridge engineering.Bridge produces flexible and knuckle owing to be subjected to the influence of dynamic load of current, the wind, earthquake etc. of variation of temperature, vehicle at the two ends of bridge.For soft junction structure length bridges such as suspension bridge, cable stayed bridges, consider this two kinds of factors simultaneously; And for rigid structure small bridge such as metal bridge, concrete bridges, because knuckle changes not quite, can ignore, so only consider the telescopic variation of length direction.Since these variations have been arranged, just need take measures necessary to the cable on the bridge that is laid at the influence of stretching and knuckle causes, eliminate or the flexible adverse effect that variation causes cable with knuckle of reduction farthest.Modern bridge generally adopts concrete or steel structure, bridge changes owing to temperature variation, humidity in running and load variations all will cause bridge structure to deform, therefore the flexible arc system of cable need be installed on bridge, and this system is taked corresponding fixation.
The model utility content
The purpose of this utility model is exactly to provide a kind of simple in structure in order to overcome the defective that above-mentioned prior art exists, firm supporting, and can improve the sliding system in the flexible arc of cable of being used in cable working life.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of sliding system that is used in the flexible arc of cable, it is characterized in that, this sliding system comprises sliding rail, sliding bottom plate and support fixation seat, described sliding rail is erected on the seat of flexible arc basis, the two ends of described sliding bottom plate are erected at respectively on the sliding rail, and described support fixation seat is located on the sliding bottom plate.
Described sliding rail frame adopts stainless steel pipe or square steel to make.
Described moving base plate is stainless steel plateform.
Described support fixation seat comprises cable bracket, support cross-arm and column, described cable bracket top cabling, described support cross-arm is located at the bottom of cable bracket, and described column is connected the bottom of support cross-arm, and the column bottom is fixed on the sliding bottom plate.
Compared with prior art, the utility model is simple in structure, firm supporting, can be good at cable is fixedly mounted on the bridge, and slide according to the situation of expanding with heat and contract with cold, farthest reduce adverse effect flexible and that the knuckle variation causes cable, the working life of having improved cable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
1 is that sliding rail, 2 is that sliding bottom plate, 3 is that support fixation seat, 4 is that cable, 5 is basic of flexible arc among the figure.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
A kind of sliding system that is used in the flexible arc of cable, its structure as shown in Figure 1, this sliding system comprises sliding rail 1, sliding bottom plate 2 and support fixation seat 3, sliding rail 1 adopts stainless steel pipe or square steel to make, be erected on the flexible arc basis seat 5, sliding rail 1 is provided with several, thereby provide different glide directions, sliding bottom plate 2 is stainless steel plateform, two ends are erected at respectively on the sliding rail 1, support fixation seat 3 is located on the sliding bottom plate 2, this support fixation seat 3 comprises cable bracket, support cross-arm and column, cable bracket top cabling 4, the support cross-arm is located at the bottom of cable bracket, column is connected the bottom of support cross-arm, and the column bottom is fixed on the sliding bottom plate 2.
The utility model is provided with several according to the shape of laying of cable 4, by support fixation seat 3 cable 4 is fixed, during use owing to expand with heat and contract with cold and bridge self flexible will cause cable to arch upward or be subjected to excessive tension force, because the uncontrolled and continuous alternating bending distortion of cable bending deflection, thereby cause the cable metal sheath fatigue cracking, cable conductor is broken, cable insulation is impaired, phenomenons such as cable joining displacement produce, finally reduced cable life, utilizing the utility model that cable 4 is slided is fixed on the flexible arc basis seat 5, thereby cable 4 can be slided within the specific limits, so just can farthest reduce adverse effect flexible and that the knuckle variation causes cable, the working life of having improved cable.
