背景技术 Background technique
±660kV银东线路所有耐张塔全部采用瓷质绝缘子，当瓷质绝缘子出现损坏及零值时必须进行更换，以往更换耐张塔单片瓷质绝缘子的方式为：高空作业人员在耐张瓷质绝缘子串上将传递滑车固定好，地面配合人员将单片瓷质绝缘子用传递绳传递至瓷质绝缘子耐张串下沿，操作人员趴伏于绝缘子串上，用手将单片瓷质绝缘子提至瓷质绝缘子串上方。此方法费时费力，且易造成高空物品掉落。形成极大安全隐患。且由于±660kV电压等级所有瓷质绝缘子盘径较大、单片绝缘子重量约为30公斤，单人根本无法将它提升至串上。 All the tension towers of the ±660kV Yindong line use porcelain insulators. When the porcelain insulators are damaged or have zero value, they must be replaced. Fix the transfer block on the string of insulators, and the ground coordinators transfer the single-piece porcelain insulator to the lower edge of the tension string of the porcelain insulator with a transfer rope. Lift above the string of porcelain insulators. This method is time-consuming and labor-intensive, and it is easy to cause high-altitude objects to fall. pose a great safety hazard. And because the diameter of all porcelain insulators with a voltage level of ±660kV is large, and the weight of a single insulator is about 30 kg, it is impossible for a single person to lift it to the string.

具体实施方式 detailed description
如附图1所示，本发明包括通过固定杆1相连接的左固定卡环2和右固定卡环3以及通过左支架4、右支架5分别和左固定卡环2、右固定卡环3相连接的滑车吊环架6，所述的滑车吊环架6上设置有挂孔9。 As shown in accompanying drawing 1, the present invention comprises the left fixed snap ring 2 and the right fixed snap ring 3 that are connected by fixed bar 1 and through left bracket 4, right bracket 5 respectively and left fixed snap ring 2, right fixed snap ring 3 The connected tackle ring frame 6 is provided with a hanging hole 9 on the block ring frame 6 .
本发明所述的左固定卡环2由一端铰连的上下两个半圆环构成，上下两个半圆环的另一端设置有左锁卡7，所述的右固定卡环3由一端铰连的上下两个半圆环构成，上下两个半圆环的另一端设置有右锁卡8。 The left fixed snap ring 2 of the present invention is composed of two upper and lower semi-circular rings hinged at one end, the other end of the upper and lower two semi-circular rings is provided with a left locking clip 7, and the right fixed snap ring 3 is hinged at one end. Connected upper and lower two semi-circular rings constitute, the other end of the upper and lower two semi-circular rings is provided with a right lock card 8.
本发明依靠双串绝缘子平行排列的结构，充分利用设备本身固有条件，利用待更换瓷质绝缘子附近绝缘子，通过本发明的左固定卡环2、右固定卡环3将本发明固定在两个绝缘子之间的钢帽上，如附图2所示，即首先打开左固定卡环2、右固定卡环3上的下半圆环，将左固定卡环2、右固定卡环3的上半圆环卡在钢帽上后，再将左锁卡7和右锁卡8旋紧，即将两个钢帽卡紧，即将本发明固定于双串绝缘子上。当作业人员在绝缘子上进行更换单片绝缘子作业时，将滑车吊钩吊挂在滑车吊环架6上的挂孔9内，地面人员通过滑车将物品传递至高空作业人员工作位置附近，高空作业人员通过滑车从作业点处拿取工器具及备品备件，对单片绝缘子进行吊装。本发明既能有效减少高空作业人员劳动强度，提高作业效率，同时又能作为工器具二次保护装置，减少了高空坠物的风险，保证了高空作业人员及地面人身安全。 The present invention relies on the parallel arrangement of double-string insulators, fully utilizes the inherent conditions of the equipment itself, utilizes the insulators near the porcelain insulators to be replaced, and fixes the present invention on the two insulators through the left fixing snap ring 2 and the right fixing snap ring 3 of the present invention. On the steel cap between them, as shown in accompanying drawing 2, promptly open the lower semicircular ring on the left fixed snap ring 2, the right fixed snap ring 3 at first, the left fixed snap ring 2, the upper half of the right fixed snap ring 3 After the circular ring is stuck on the steel cap, the left locking clip 7 and the right locking clip 8 are screwed tightly, that is, the two steel caps are fastened, and the present invention is fixed on the double-string insulator. When the operator performs the operation of replacing the single-piece insulator on the insulator, hang the tackle hook in the hanging hole 9 on the tackle ring frame 6, and the ground personnel pass the items to the vicinity of the working position of the high-altitude worker through the tackle, and the high-altitude worker Take the tools and spare parts from the operation point through the tackle, and hoist the monolithic insulator. The invention can not only effectively reduce the labor intensity of high-altitude workers and improve work efficiency, but also can be used as a secondary protection device for tools, reducing the risk of falling objects and ensuring the personal safety of high-altitude workers and the ground.
