Description
技术领域 technical field
本发明涉及变电站施工领域，具体地，本发明涉及一种用于变电站内跨越管型母线进行带电放线施工的滑轮式导线滑车，更具体地，本发明涉及一种滑轮式导线滑车用牵引绳弹性夹持机构。 The present invention relates to the field of substation construction. Specifically, the present invention relates to a pulley-type wire block used for carrying out live wire laying construction across a tubular bus in a substation. More specifically, the present invention relates to a pulley-type wire block traction rope Elastic clamping mechanism. the
背景技术 Background technique
随着城市化进程的加剧，经济的发展迅猛，用电负荷逐年激增，对供电可靠性的要求也越来越高。尤其是在人口密度大的大城市，对供电可靠性的要求更高。目前上海有逾百座变电站，由于电网运行的需要，有较多的变电站需要进行增容改造、缺陷消除及设备检修。 With the intensification of the urbanization process and the rapid economic development, the electricity load has increased year by year, and the requirements for the reliability of power supply are also getting higher and higher. Especially in large cities with high population density, the requirements for power supply reliability are higher. At present, there are more than 100 substations in Shanghai. Due to the needs of power grid operation, many substations need to undergo capacity expansion, defect elimination and equipment maintenance. the
对于变电站的增容改造、缺陷消除及设备检修等工作，如果采用传统施工工艺及方法，必须通过全站停电的方式来进行，在正常运行方式下很难实现，即使能安排停电也会对电网的安全运行带来较大风险。 For substation capacity expansion, defect elimination, and equipment maintenance, if traditional construction techniques and methods are used, it must be carried out through a power outage of the entire station, which is difficult to achieve in normal operation. Even if a power outage can be arranged, it will cause damage to the power grid safe operation poses a greater risk. the
为了减少设备配合停电时间，提高电网运行可靠性，确保电网的安全运行，需要通过技术攻关，实现在变电站内管母线正常运行的状态下，跨越带电母线展放导线。 In order to reduce the outage time of equipment coordination, improve the reliability of power grid operation, and ensure the safe operation of the power grid, it is necessary to make technical breakthroughs to realize the deployment of conductors across the live busbar under the normal operation of the busbar in the substation. the
已有的双导线双头滑车或者单导线滑车适用于变电站内跨越管型母线带电放线作业用，上述双分裂导线双头滑车可以不停电施工，不会造成管型母线与导线的大面积损伤。 The existing double-conductor double-head block or single-conductor block is suitable for the live discharge operation across the tubular busbar in the substation. The above-mentioned double-split conductor double-head block can be constructed without power failure, and will not cause large-scale damage to the tubular busbar and conductors. . the
已有的双导线双头滑车或者单导线滑车使用时，将双头滑车或者单导线滑车悬挂在牵引绳(承力)上；其中部设有牵引绳支撑部(孔)，其下部设有导线展放用钩挂部。将单导线放置在导线展放用钩挂部。拖动牵引绳，单导线即可同步跟随双头滑车移动。 When the existing double-conductor double-head block or single-conductor block is used, the double-head block or single-conductor block is suspended on the traction rope (bearing force); the middle part is provided with a traction rope support part (hole), and its lower part is provided with a wire Hanging part for display. Place the single lead wire on the lead wire deployment hook. Drag the traction rope, and the single wire can move synchronously with the double-head block. the
在牵引绳上，每隔2米悬挂一个双头滑车，确保单导线始终与下方运行中的管型母线足够的安全距离。从而实现在变电站内管母线正常运行的状态下，跨越带电母线展放导线。 On the traction rope, hang a double-head block every 2 meters to ensure that the single conductor is always at a sufficient safety distance from the running tubular busbar below. In this way, under the normal operation state of the pipe bus in the substation, the wires can be deployed across the live bus. the
但现有上述导线滑车的缺点是，因导线重量较大，另一方面，为支撑牵引绳，用于放置和牵引绳索的所述牵引绳支撑部(孔)开口处较小，同时，牵引绳索表面粗糙，在牵引过程中，牵引施力通常都与所述上述导线滑车成一较大的角度，因此，在牵引过程 中，往往发生因牵引绳索的开口处变化的阻尼而导致伸缩卡住，费时费力，影响施工效率。另外，如果所述牵引绳支撑部(孔)开口处较大，则牵引不稳，且导致牵引绳索容易脱落。 But the shortcoming of existing above-mentioned wire tackle is that, because the wire weight is bigger, on the other hand, in order to support the pulling rope, the opening of the said pulling rope support part (hole) for placing and pulling the rope is relatively small, meanwhile, the pulling rope The surface is rough. During the traction process, the traction force usually forms a relatively large angle with the above-mentioned wire tackle. Therefore, during the traction process, telescopic jamming often occurs due to the damping at the opening of the traction rope, which is time-consuming. It is laborious and affects the construction efficiency. In addition, if the opening of the traction rope support portion (hole) is relatively large, the traction will be unstable and the traction rope will easily fall off. the
以此，本领域要求一种导线滑车，所述导线滑车用于放置和牵引绳索的所述牵引绳支撑部(孔)具有弹性支撑力及夹持力，在牵引过程中，不会发生因牵引绳索的开口处变化的阻尼而导致牵引绳卡住，费时费力，影响施工效率。另外，要求所述牵引绳在支撑部(孔)开口处不容易脱落。 Therefore, the field requires a wire block, the pull rope support portion (hole) of the wire block used for placing and pulling the rope has elastic support and clamping force, and during the pulling process, there will be no damage caused by pulling The variable damping at the opening of the rope causes the traction rope to get stuck, which takes time and effort and affects construction efficiency. In addition, it is required that the pulling rope is not easy to fall off at the opening of the support part (hole). the
