Abstract
The present invention relates to a sliding system used in a cable expansion arc. The sliding system comprises a sliding rail, a sliding base plate and a supporting-fixing seat; the sliding rail is supported on a base seat of the expansion arc; and both ends of the sliding base plate are respectively supported on the sliding rail; and the supporting-fixing seat is arranged on the sliding base plate. Compared with the prior art, the sliding system used in the cable expansion arc in the invention has the advantages of simple structure and firm support; the sliding system can also assist in securely fixing a cable on a bridge; and further, the sliding system can realize slide according to expansion caused by heat and contraction caused by cold so as to maximally decrease adverse effects of expansion and folding angle changes on the cable, thereby prolonging a service life of the cable.
Description
Technical field
The present invention relates to a kind of cable connecting arrangement, especially relate to a kind of cable expansion arc sliding system.
Background technique
Along with the development of regional economy and the refinement of zone location, the domestic exploitation to offshore island day by day heat up, further pay attention in recent years.A plurality of islands, the whole nation have been warded off as Shipbuilding Base, generating base, combustion gas terminal, port and pier etc., wherein be 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 Material Transportation problem for what coordinate these bases, bridge also often is happy to build to connect all islands and continent by local government.This just provides a kind of new way for solving long-term tired electric power transportation problem of scratching island.
220kV Chongming networking project is laid 2 go back tos 220kV cable runs station, 220kV Chen Jia town to Chongming Island from station, 220kV continent sea, and cut-offs and encircle the station, 220kV Changxing be positioned on Changxing Island.By detailed investigation, analysis, comparison, engineering is determined the Shanghai Chong Su major path route scheme that employing is being built, 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, be the current bridge tunel engineering of maximum in the world, be also the power cable bridge engineering of the domestic the first 220kV electric pressure of China simultaneously.Bridge, due to the impact of the dynamic load of current, the wind of the variation that is subject to temperature, vehicle, earthquake etc., produces flexible and knuckle at the two ends of bridge.For soft structure big-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, therefore only consider the telescopic variation of length direction.Since these variations have been arranged, the impact that just need to cause for flexible and knuckle, take necessary measure to the cable on the bridge that is laid in, and eliminates or farthest reduce to stretch to change with knuckle the adverse effect that cable is caused.Modern bridge generally adopts concrete or steel structure, bridge due to temperature variation, humidity, changes in running and load variations all will cause bridge structure to deform, therefore need to be on bridge the flexible arc system of installing cables, and this system is taked to corresponding fixation.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of simple in structure in order to overcome the defect that above-mentioned prior art exists, firm supporting, and can improve the cable cable expansion arc sliding system in working life.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of cable expansion arc sliding system, it is characterized in that, this sliding system comprises sliding rail, sliding bottom plate and supports fixed base, described sliding rail is erected on flexible arc foundation base, the two ends of described sliding bottom plate are erected at respectively on sliding rail, and described support fixed base 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 fixed base 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 to the bottom of support cross-arm, and the column bottom is fixed on the sliding bottom plate.
Compared with prior art, the present invention is simple in structure, firm supporting, can be good at cable is fixedly mounted on 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.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure, 1 is that sliding rail, 2 is that sliding bottom plate, 3 is that cable, 5 is the arc foundation base that stretches for supporting fixed base, 4.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment
A kind of cable expansion arc sliding system, its structure as shown in Figure 1, this sliding system comprises sliding rail 1, sliding bottom plate 2 and support fixed base 3, sliding rail 1 adopts stainless steel pipe or square steel to make, be erected on flexible arc foundation base 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 sliding rail 1, supporting fixed base 3 is located on sliding bottom plate 2, this support fixed base 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 to the bottom of support cross-arm, the column bottom is fixed on sliding bottom plate 2.
The present invention is provided with several according to the shape of laying of cable 4, by supporting fixed base 3, cable 4 is fixed, during use owing to expanding with heat and contract with cold and the flexible of bridge self will cause cable to arch upward or be subject to excessive tension force, due to the uncontrolled and continuous alternating bending distortion of cable bend distortion, thereby cause the cable metal sheath fatigue cracking, cable conductor is broken, cable insulation is impaired, the phenomenons such as cable joining displacement produce, finally reduced cable life, utilize the present invention that cable 4 is slided and is fixed on flexible arc foundation base 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, improved the working life of cable.
