Description
技术领域technical field
本发明涉及工程机械领域和输电线路异物清除技术领域,具体涉及一种跟斗滑车及架空线路上挂取跟斗滑车的方法。The invention relates to the field of engineering machinery and the technical field of foreign matter removal for power transmission lines, in particular to a bucket block and a method for hanging and picking up the bucket block from an overhead line.
背景技术Background technique
架空输电线路是电力系统的重要组成部分之一,承担着电力输送的重要功能,主要由导线、架空地线、绝缘子串、杆塔、接地装置等部分组成。其任意组成部分出现问题,都将会直接影响到输电线路的安全稳定运行。然而输电线路架设在野外,长年经受自然条件和四周环境的影响,因此时常会发生雷害、鸟害、污闪、冰闪和外力破坏等事故。The overhead transmission line is one of the important components of the power system, which undertakes the important function of power transmission, and is mainly composed of conductors, overhead ground wires, insulator strings, towers, grounding devices and other parts. Any problem in any of its components will directly affect the safe and stable operation of the transmission line. However, transmission lines are erected in the wild, and have been affected by natural conditions and the surrounding environment for many years. Therefore, accidents such as lightning damage, bird damage, pollution flashover, ice flashover, and external damage often occur.
近年来,随着建筑的快速增长,架空线路附近的施工点随之增加,外力破坏导致导线断股、散股的现象屡见不鲜,为确保线路安全稳定运行,应及时对受损导线进行修补。在导线修补工作中,地面作业人员需要将跟斗滑车沿导线滑至导线损伤处,再将绝缘软梯吊起在导线上挂好,导线修补工才能沿着绝缘软梯进入线路,进行修补工作。由于架空线路所处环境不同,不是所有的线路通道下方都能行走(如河流、湖泊、树林、小型建筑物等)。此时需要采用另一种作业方法,即在塔身附近悬挂软梯头,在横担上留有控制绳,等作业人员进入梯头后,滑至修补处进行修补。无论哪种方法,工作人员都不能很快到达作业点,前者受环境因素影响,后者则会消耗工作人员大量的体力,均存在弊端。那么如何使跟头滑车第一时间到达损伤处,就成为了需要解决的问题。In recent years, with the rapid growth of buildings, the number of construction points near overhead lines has increased, and it is not uncommon for wires to break and loose strands due to external damage. In order to ensure the safe and stable operation of lines, damaged wires should be repaired in time. In the wire repair work, the ground operator needs to slide the tumbler along the wire to the wire damage, and then hoist the insulating ladder on the wire and hang it, so that the wire repairer can enter the line along the insulating ladder to carry out repair work. Due to the different environments of overhead lines, not all line passages can be walked under (such as rivers, lakes, woods, small buildings, etc.). At this time, another operation method needs to be adopted, that is, a soft ladder head is hung near the tower body, and a control rope is left on the cross arm. After the operator enters the ladder head, it slides to the repairing place for repair. No matter which method, the staff can not reach the operation point quickly, the former is affected by environmental factors, and the latter consumes a lot of physical strength of the staff, both of which have disadvantages. Then how to make the somersault block reach the damaged place in the first time has become a problem that needs to be solved.
在220kV及以下的输电线路中,通常采用单根导线或双分裂导线的连接方式。由于导线的规格所限,作业人员无法通过走线的方式到达损伤处,这就需要借助梯头来进行修补工作。如若将剃头挂在导线上,则需要通过跟斗滑车与绝缘绳相配合。通常导线上挂跟斗滑车是由一名作业人员登上与损伤处相邻一基杆塔的横担处,用绝缘滑车和绝缘绳将所需的跟斗滑车与绝缘操作杆传递至塔上,最后塔上作业人员使用绝缘操作杆,将带有绝缘绳的跟斗滑车挑挂到需修补相的导线上。整个过程的难点就在于绝缘操作杆的挑挂,为了保证安全,绝缘操作杆的长度往往大于最小安全距离规定,在挑挂起跟斗滑车后,会给操作带来极大的不便,再加上作业现场在室外,容易受风的影响,从而使得整个挑挂过程更为艰难。常规跟斗滑车挂取存在三大弊端:1.常规跟斗滑车较重,挂取不方便。2.无封口,容易从导线脱出。3.挂取作业较繁琐,费时费力。In the transmission line of 220kV and below, the connection method of single wire or double split wire is usually used. Due to the limited specifications of the wires, operators cannot reach the damaged part by routing, which requires the use of ladder heads for repair work. If the razor is hung on the wire, it needs to cooperate with the insulating rope through the bucket block. Usually the wire is hung with a bucket block by an operator on the cross arm of a base tower adjacent to the damaged part, and the required bucket block and insulation operating rod are transferred to the tower with an insulating block and an insulating rope, and finally the tower The upper operator uses the insulated operating rod to pick and hang the trolley with the insulated rope on the wire to be repaired. The difficulty of the whole process lies in the hanging of the insulating operating rod. In order to ensure safety, the length of the insulating operating rod is often greater than the minimum safety distance. The job site is outdoors, which is easily affected by the wind, which makes the whole hanging process more difficult. There are three major disadvantages in the conventional tumbler tackle: 1. The conventional tumbler tackle is heavy and inconvenient to pick up. 2. No sealing, easy to come out from the wire. 3. The loading and unloading operation is cumbersome, time-consuming and labor-intensive.
发明内容Contents of the invention
鉴于上述现有技术的不足,本发明旨在提供一种架空线路上无人机挂取跟斗滑车的方法,该方法中的跟斗滑车自身重量较轻,在作业过程中具有较好的灵活性,受到拉力后不易从导线上脱出,确保梯头能顺利拉上导线,同时利用该方法挂取跟斗滑车省时省力且不受线路通道环境影响。In view of the above-mentioned deficiencies in the prior art, the present invention aims to provide a method for unmanned aerial vehicles to hang and pick up the bucket tackle on the overhead line. The bucket tackle in this method is lighter in weight and has better flexibility during operation After being pulled, it is not easy to come out from the wire, ensuring that the ladder head can pull up the wire smoothly.

挂跟斗滑车的过程如下:首先,将一有弹性的绳索穿过挂环4固定后,挂在无人机上,连接无人机和跟斗滑车;将软梯连接至定滑轮2上,人工操作无人机起飞,此时由于无人机向上的牵引力作用,闭合锁片3沿着挂钩1竖直方向的两侧壁上滑,由于水平限位柱15与条形通孔32的卡合,闭合锁片3不会与挂钩1分离,且能够使得挂钩1的开口13在操作过程中始终处打开状态;其次,根据无人机拍摄系统实时传输的画面找到导线上需要修补的地方,操作无人机调整高度和方向,使得导线能够通过挂钩1的开口13进入沟槽14内,此时,松开绳索,失去无人机的牵引后,闭合锁片3由于自身重力的作用沿着挂钩1竖直方向的两侧壁下移,弧形的锁止端33能够与所述下钩体11弧形的一侧相互贴合(闭合锁片3靠近开口13的一端部31向下移动插入卡槽121内),开口13封闭;最终,将跟斗滑车挂在架空线路的导线上,作业人员将软梯的一边固定在一固定物上,通过攀爬软梯的另一边进而登上软梯进行高处修补导线的作业。The process of hanging the tumbler block is as follows: First, after fixing an elastic rope through the hanging ring 4, hang it on the UAV to connect the UAV and the tumbler block; At this time, due to the upward traction effect of the drone, the closing lock piece 3 slides up along the two side walls of the vertical direction of the hook 1, and due to the engagement of the horizontal limit post 15 and the bar-shaped through hole 32, the closing lock The piece 3 will not be separated from the hook 1, and can make the opening 13 of the hook 1 always open during the operation; secondly, according to the real-time transmission of the UAV shooting system, find the place that needs to be repaired on the wire, and operate the UAV Adjust the height and direction so that the wire can enter the groove 14 through the opening 13 of the hook 1. At this time, after the rope is released and the traction of the drone is lost, the closing lock piece 3 is vertically along the hook 1 due to its own gravity. The two side walls in the direction move down, and the arc-shaped locking end 33 can be fitted with the arc-shaped side of the lower hook body 11 (the end 31 of the closing lock piece 3 close to the opening 13 moves downward and is inserted into the card slot 121 inside), the opening 13 is closed; finally, the tumbler block is hung on the wire of the overhead line, and the operator fixes one side of the ladder to a fixed object, and climbs the other side of the ladder to climb the ladder to repair the wire at a high place Operation.
取跟斗滑车的过程如下:在软梯上操作的工作人员将穿过挂环4的绳索套在无人机上,重新连接无人机和跟斗滑车,然后工作人员下软梯,操作无人机向上拉动闭合锁片3,由于无人机的牵引力的作用,闭合锁片3沿着挂钩1竖直方向的两侧壁上滑,弧形的锁止端33与所述下钩体11弧形的一侧分离(闭合锁片3靠近开口13的一端部31向上移动脱离卡槽121),开口13打开,从而导线从挂钩1的开口13内脱出,使跟斗滑车与导线分开,取下跟斗滑车。The process of taking the tumble block is as follows: the staff operating on the soft ladder puts the rope passing through the hanging ring 4 on the drone, reconnects the drone and the tumble block, and then the staff gets off the soft ladder and operates the drone to pull up and close The locking piece 3, due to the traction force of the drone, the closed locking piece 3 slides up along the two side walls in the vertical direction of the hook 1, and the arc-shaped locking end 33 is connected to the arc-shaped side of the lower hook body 11 Separation (one end 31 of the closed locking piece 3 close to the opening 13 moves upwards and escapes from the draw-in groove 121), the opening 13 is opened, and the lead wire escapes from the opening 13 of the hook 1, so that the tumble block is separated from the lead wire, and the tumble block is removed.
上述实施例为本发明较佳的实施方式,但本发明的实施方式并不受上述实施例的限制,其他的任何未背离本发明的精神实质与原理下所作的改变、修饰、替代、组合、简化,均应为等效的置换方式,都包含在本发明的保护范围内。The above-mentioned embodiment is a preferred embodiment of the present invention, but the embodiment of the present invention is not limited by the above-mentioned embodiment, and any other changes, modifications, substitutions, combinations, Simplifications should be equivalent replacement methods, and all are included in the protection scope of the present invention.
