Description

一种电力施工用线缆牵拉装置A cable pulling device for electric power construction

技术领域technical field

本发明涉及一种电力施工用线缆牵拉装置。The invention relates to a cable pulling device for electric power construction.

背景技术Background technique

在输变电线路挂线时，需要将大线径导线挂到绝缘子槽上。由于一般施工场合在野外等场合，难以使用自动化设备，需要作业人员站在脚扣上采用简易的滑轮结构将导线放到绝缘子槽上。整个作业过程中，由于导线直径较大，自重极大，作业人员在高处很难拖动导线，且由于高处用力不方便线路使得挂线十分困难，并且作业时需脚部用力支撑容易破坏脚扣，具有一定的安全隐患。When hanging wires on power transmission and transformation lines, it is necessary to hang large-diameter wires on the insulator slot. Since the general construction site is in the field, it is difficult to use automation equipment, and it is necessary for the operator to stand on the foot buckle and use a simple pulley structure to place the wire on the insulator slot. During the whole operation process, due to the large diameter of the wire and the huge weight, it is difficult for the operator to drag the wire at a high place, and it is very difficult to hang the wire due to the inconvenient line due to the force at the high place, and it is easy to damage the wire when it needs to be supported by the feet. The foot buckle has certain potential safety hazards.

使用时，电力工人背上背包4，将支撑纵板1放在胸前，缓冲气囊3起到保护的作用，然后就携带整个装置爬上电力线杆，牵拉线缆时，先将线缆放在前辊轴12、下辊轴19和后辊轴27上，线缆会因为重力将伸缩柱20压下，因此下辊轴19、支撑板24也同步向下移动，支撑板24下移会带动横连杆14沿滑轨13向外滑动，横连杆14末端同时会向上翘起，进而推动外斜连杆15下端向上撬动，由于杠杆原理，外斜连杆15中部绕转轴16转动，外斜连杆15的上端向下移动，进而带动连接板17斜向下移动，最后使上辊轴18压在线缆的侧上方，由于采用左右对称的结构，两侧的上辊轴18同步压在线缆的两侧上方，因此线缆会夹在两个上辊轴18和下辊轴19之间。当电动伸缩杆6向后牵拉自重力夹线组件8时，线缆会受到向前的反作用力，线缆初始阶段会向前移动一下，此时压在线缆上的两侧的上辊轴18会逆时针转动，从而将挤压凸块28转到下方，使上辊轴18与下辊轴19之间的空间进一步缩小，从而将线缆夹紧，而且电动伸缩杆6向后牵拉的力量越大，线缆所受到的反作用力越大，挤压凸块28挤压的线缆越紧，最后将线缆牵拉到电力工人面前。在牵拉完成以后将自重力夹线组件8向前推动，线缆收到向后的反作用力，从而使上辊轴18顺时针转动，从而使挤压凸块28向上转动，也增加了上辊轴18与下辊轴19之间的空间，然后抬起线缆，在弹簧21的作用下，伸缩柱20上升，然后横连杆14沿滑轨13回缩，外斜连杆15的上端向下移动，进而带动连接板17斜向上移动，就可以将线缆从自重力夹线组件8上取出来了。During use, the electric worker puts the backpack 4 on his back, puts the support vertical plate 1 on his chest, and the buffer airbag 3 plays a protective role, and then climbs up the power line pole with the whole device, and when pulling the cable, put the cable first. On the front roller shaft 12, the lower roller shaft 19 and the rear roller shaft 27, the cable will press the telescopic column 20 down due to gravity, so the lower roller shaft 19 and the support plate 24 also move downward synchronously, and the support plate 24 will move downwards Drive the horizontal connecting rod 14 to slide outward along the slide rail 13, and the end of the horizontal connecting rod 14 will be tilted upward at the same time, and then push the lower end of the external oblique connecting rod 15 to pry upward. Due to the principle of leverage, the middle part of the external oblique connecting rod 15 rotates around the rotating shaft 16 , the upper end of the outer inclined connecting rod 15 moves downward, and then drives the connecting plate 17 to move obliquely downward, and finally makes the upper roller 18 press on the upper side of the cable. Due to the left-right symmetrical structure, the upper roller 18 on both sides Simultaneously presses over both sides of the cable so that the cable is clamped between the two upper 18 and lower 19 rollers. When the electric telescopic rod 6 pulls the self-gravity clamp assembly 8 backward, the cable will be subjected to a forward reaction force, and the cable will move forward at the initial stage. At this time, the upper rollers on both sides of the cable will press The shaft 18 will rotate counterclockwise, thereby turning the extruding lug 28 to the bottom, further reducing the space between the upper roller shaft 18 and the lower roller shaft 19, thereby clamping the cable, and the electric telescopic rod 6 is pulled backward The greater the pulling force, the greater the reaction force suffered by the cable, and the tighter the cable extruded by the extruding projection 28, the cable is finally pulled in front of the electric worker. After the pulling is completed, the self-gravity clamp assembly 8 is pushed forward, and the cable receives a backward reaction force, so that the upper roller shaft 18 rotates clockwise, thereby causing the extrusion protrusion 28 to rotate upwards, and the upper roller shaft 28 is also increased. The space between the roller shaft 18 and the lower roller shaft 19, then lift the cable, under the action of the spring 21, the telescopic column 20 rises, and then the horizontal connecting rod 14 retracts along the slide rail 13, and the upper end of the outer oblique connecting rod 15 Moving down, and then driving the connecting plate 17 to move obliquely upward, the cable can be taken out from the gravity clamping assembly 8 .

以上所述仅是本专利的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本专利技术原理的前提下，还可以做出若干改进和替换，这些改进和替换也应视为本专利的保护范围。The above description is only the preferred implementation mode of this patent.
