Description

一种电力紧线器 技术领域
本发明涉及电力设备辅助技术领域，具体为一种电力紧线器。
背景技术
紧线器，又叫棘轮收紧器，是在架空线路敷设施工中作为拉紧导线用的，使用时先将紧线器上的钢丝绳或镀锌铁线松开，并固定在横担上，用夹线钳夹住导线，然后扳动专用板手，由于棘爪的防逆转作用，逐渐把钢丝绳或镀锌铁线绕在棘轮滚筒上，使导线收紧，把收紧的导线固定在绝缘子上，然后先松开棘爪，使钢丝绳或镀锌铁线松开，再松开夹线钳，最后把钢丝绳或镀锌铁线绕在棘轮的滚筒上。
但是一般的电力紧线器在使用时，由于扳动扳手时没有支点支撑紧线器，所以每次扳动扳手都比较费力，增加工人的劳动强度，而且在通过夹线钳夹住导线时，夹持力比较固定，所以对于粗细尺寸不一样的电线不能够做到更好的夹持紧固作用，容易在紧线过程中脱落。
因此对高可靠性产品的需求迫在眉睫，故而我们提出了一种电力紧线器，其具有紧线工作省力以及夹线更加紧固的作用。
发明内容
(一)解决的技术问题
针对现有技术的不足，本发明提供了一种电力紧线器，具备紧线工作省力以及夹线更加紧固等优点，解决了上述扳动扳手比较费力，增加工人的劳动强度，夹持力比较固定，对于粗细尺寸不一样的电线不能更好的夹持紧固的问题。
(二)技术方案
为实现上述紧线工作省力以及夹线更加紧固的目的，本发明提供如下技 术方案：一种电力紧线器，包括框架，所述框架的内部转动连接有缠绕杆，所述缠绕杆的外侧缠绕有钢丝绳，所述框架的底端设置有承重块，且所述钢丝绳的另一端缠绕在承重块内部的滑轮外侧，所述承重块的底端转动连接有挂钩，所述框架的顶端活动连接有紧固部件，所述框架的外侧设置有省力部件。
进一步的，所述紧固部件包括连接块，所述连接块转动连接在框架的顶部，所述连接块的顶端固定安装有固定筒，所述连接块的中部开设有通槽，所述固定筒的内壁开设有限位槽，所述固定筒的内部转动连接有转轮，所述固定筒的内壁固定安装有固定块，所述固定块的两侧均转动连接有转柱，所述转轮的外侧固定安装有挤压块。
进一步的，所述省力部件包括外壳，所述外壳固定安装在框架的外侧，所述外壳的外侧中部转动连接有套环，所述外壳的外侧设置有扳手，所述外壳的内部转动连接有转筒，所述转筒位于外壳外部的一端固定安装有外棘轮，所述外棘轮的底部外侧铰接有外棘爪，所述套环的内部转动连接有转轴，所述转轴的外侧固定安装有发条弹簧，所述转筒的内壁固定安装有内齿环，所述内齿环的内部啮合连接有传动齿轮，所述传动齿轮的右侧固定安装有内棘轮，所述内棘轮的底部外侧铰接有内棘爪。
进一步的，所述通槽贯通进固定筒的内部，且位于固定筒的内部中心，所述转轮在固定筒的内部阵列设置有六组，通过通槽方便将电线插进固定筒以及连接块的内部，同时六组转轮会围绕在电线的外侧周围。
进一步的，所述转柱的另一端转动连接在限位槽的外侧中部，所述转轮远离固定筒中心的一端位于限位槽的内部，通过转柱作为转轮的支点，方便转轮转动，同时通过限位槽对转轮进行限位，防止转轮转动时偏斜。
进一步的，所述挤压块凸出转轮的外侧，且挤压块凸出转轮的厚度随着挤压块的弧度慢慢增加，通过转轮转动带动挤压块挤压向电线，进而会随着 转轮的转动带动更厚的挤压块的一侧挤压电线，从而挤压的越来越紧。
进一步的，所述转筒穿过框架的中部，所述框架靠近转筒的一侧内部滚动连接有滚珠，通过滚珠能够减少转筒沿着框架中心转动时产生的摩擦力，节省力气。
进一步的，所述转轴位于外壳外侧的一端固定安装在扳手的外侧，所述发条弹簧的外侧固定安装在套环的内壁上，通过向上掀起扳手会带动转轴在套环的内部转动，进而会压缩发条弹簧，此时发条弹簧会持续给予套环反向复位的力，进而能够向下转动扳手，节省力气。
进一步的，所述传动齿轮的直径小于内齿环的直径，所述转轴固定安装在内棘轮中心，通过转轴会带动内棘轮同步转动，进而能够通过传动齿轮带动内齿环转动，而由于传动齿轮的直径小于内齿环的直径，故而转动时更加省力。
(三)有益效果
与现有技术相比，本发明提供了一种电力紧线器，具有以下有益效果：
1.该电力紧线器，通过将电线插进通槽内，并且留出长度，通过将电线想外拉，会带动限位槽转动，进而会带动挤压块转动挤压向电线，由于挤压块的厚度随着弧度逐渐加厚，所以电线越被收紧挤压块对电线挤压的就越紧固，进而能够提高对电线的紧固作用，同时根据挤压块挤压在电线上的厚度不同可以适用于不同粗细尺寸的电线。
2.该电力紧线器，通过上下来回扳动扳手会带动传动齿轮转动，通过内齿环会带动转筒转动，进而能够通过外棘轮带动缠绕杆转动对钢丝绳进行收卷缠绕，所以能够慢慢的收紧电线，而由于传动齿轮的直径小于内齿环的直径，故而转动时更加省力，同时在向上扳动扳手时，会通过转轴对发条弹簧进行压缩，通过压缩后的发条弹簧会持续给予套环反向复位的力，进而会在向下扳动扳手时辅助扳手向下转动，从而能够进一步节省力气。

请参阅图6，省力部件7包括外壳71，外壳71固定安装在框架1的外侧，外壳71的外侧中部转动连接有套环72，外壳71的外侧设置有扳手73，外壳71的内部转动连接有转筒74，转筒74穿过框架1的中部，框架1靠近转筒74的一侧内部滚动连接有滚珠，通过滚珠能够减少转筒74沿着框架1中心转动时产生的摩擦力，节省力气，转筒74位于外壳71外部的一端固定安装有外棘轮75，外棘轮75的底部外侧铰接有外棘爪76。
请参阅图6-7，套环72的内部转动连接有转轴721，转轴721位于外壳71外侧的一端固定安装在扳手73的外侧，转轴721的外侧固定安装有发条弹簧722，发条弹簧722的外侧固定安装在套环72的内壁上，通过向上掀起扳手73会带动转轴721在套环72的内部转动，进而会压缩发条弹簧722，此时发条弹簧722会持续给予套环72反向复位的力，进而能够向下转动扳手73，节省力气。
请参阅图6和图8，转筒74的内壁固定安装有内齿环741，内齿环741的内部啮合连接有传动齿轮742，传动齿轮742的直径小于内齿环741的直径，传动齿轮742的右侧固定安装有内棘轮743，转轴721固定安装在内棘轮743中心，通过转轴721会带动内棘轮743同步转动，进而能够通过传动齿轮742带动内齿环741转动，而由于传动齿轮742的直径小于内齿环741的直径，故而转动时更加省力，内棘轮743的底部外侧铰接有内棘爪744。
工作原理：请参阅图1-8，首先将钢丝绳3松开并且将挂钩5拉出挂在固定物上，然后将需要收紧的电线插进固定筒62的内部中心，电线通过通槽63穿过连接块61留有足够的长度，然后将电线向外拉出，此时会带动限位槽64转动，进而会带动挤压块651对电线进行挤压，如图5所示，所以越收紧电线挤压块651对电线挤压的越紧固；通过六组挤压块651一起挤压向位于固定筒62中心的电线，进而能够提高对电线的紧固作用，而且根据挤压块651挤压在电线上的厚度不同可以适用于不同粗细尺寸的电线；
之后通过向下扳动扳手73带动转轴721在套环72的内部转动，进而会通过内棘轮743带动传动齿轮742向下转动，所以会通过内齿环741带动转筒74同步转动，由于传动齿轮742的直径小于内齿环741的直径，滚珠会减少转筒74和框架1之间的摩擦力，故而转动时更加省力，而转筒74会通过外棘轮75带动缠绕杆2转动，所以会对钢丝绳3进行缠绕收卷，进而能够慢慢的拉紧电线；
与此同时，由于需要上下来回扳动扳手73收紧电线，而在向上扳动扳手73时，会带动转轴721向上转动，进而会压缩发条弹簧722，此时被压缩的发条弹簧722会持续给予套环72反向复位的力，进而会在向下扳动扳手73时辅助扳手73向下转动，进一步节省力气。
同时会对发条弹簧722进行压缩，此时发条弹簧722收缩持续给予套环72反向复位的力，所以在向上扳动扳手73时能够辅助向上扳动扳手73，节 省向上扳动扳手73的力气，
综上所述，该电力紧线器，通过将电线插进通槽63内，并且留出长度，通过将电线想外拉，会带动限位槽64转动，进而会带动挤压块651转动挤压向电线，由于挤压块651的厚度随着弧度逐渐加厚，所以电线越被收紧挤压块651对电线挤压的就越紧固，进而能够提高对电线的紧固作用，同时根据挤压块651挤压在电线上的厚度不同可以适用于不同粗细尺寸的电线。
通过上下来回扳动扳手73会带动传动齿轮742转动，通过内齿环741会带动转筒74转动，进而能够通过外棘轮75带动缠绕杆2转动对钢丝绳3进行收卷缠绕，所以能够慢慢的收紧电线，而由于传动齿轮742的直径小于内齿环741的直径，故而转动时更加省力，同时在向上扳动扳手73时，会通过转轴721对发条弹簧722进行压缩，通过压缩后的发条弹簧722会持续给予套环72反向复位的力，进而会在向下扳动扳手73时辅助扳手73向下转动，从而能够进一步节省力气。
