Abstract

The high-voltage cable hook is used for only unfolding the drop switch under the condition of not stopping a conveying circuit, the high-voltage cable can be freely connected with or disconnected from the lower end of the drop switch, and phase sequence adjustment can be conveniently completed. The utility model discloses constitute by holding in the palm fork, couple and cable head, its simple structure, convenient to use, labour saving and time saving, safe and reliable, the specially adapted high-tension apparatus removes places such as frequent mine.

Description

High-voltage cable hook

The utility model is that height is detested the connecting device between cable and the drop switch.

High-tension apparatus will move often, mine power shovel particularly, hidden hole drilling moves frequently, and cable unloads or connects from the drop switch lower end often, whenever unload, connect once, not only need to choose out drop switch, and the whole transmission line of drop switch upper end to have a power failure, can connect or unload the operation of cable, influence a sheet of, and high pressure has a power failure, and strict, formality is cumbersome.

General high voltage equipment all has phase sequence now, never allows counter-rotating, and the high-tension apparatus cable is not once to connect phase sequence just correctly sometimes; sometimes want secondary even three times, whenever carry out one and less importantly stop sending the primary transmission line road, formality is cumbersome; time-consuming, influence surface is big, has safety problem again.

The purpose of this utility model is exactly in order to address the above problem, and a kind of high-tension cable hook is provided, and like this, needn't stop ultra-high-tension power transmission line, and high-tension cable just can freely unload or connect.

The utility model is that hook and cable end are formed by the holder fork, is characterized in the holder fork by carriage, and the trustship of U type, roller, axle and valve are formed.Roller is movably connected in the top of trustship by axle, and the trustship middle and lower part has the notch of certain-length, and a valve is equipped with on the notch limit.Fixedly connected with the middle part of trustship in the rear end of U type carriage, the connection between them keeps certain angle, and U type carriage middle part has a notch.

Hook is by base, and return spring is regulated nut and support and formed, and the first half has certain plane inclined behind the base, and has a hole.Base is connected for whole with support, and top, base front side is equipped with and is regulated bolt and return spring; Mid-stent has a notch.

Cable end is by T type cable contact, sealing ring, and the end socket cover is formed.Three single-phase terminations of T type cable contact and cable connect, and sealing ring and end socket cover connect with cable end.

Further specify below in conjunction with accompanying drawing.

Fig. 8 is that each parts of the utility model are used schematic diagram.

As Fig. 1,2,3, holder fork 12 is by U type carriage 1, roller 2, axle 3, trustship 4 and valve 5 are formed, roller 2 is movably connected in the top of trustship 4 by axle 3, the middle and lower part of trustship 4 has the notch of certain-length, and this notch is used for being enclosed within the top of insulating rod 13, and with valve 5 trustship 4 and insulating rod 13 is fixed up.Fixedly connected with trustship 4 middle parts in the rear end of U type carriage 1, the connection between them keeps certain angle, and there is a notch at the middle part of U type carriage 1, is used for placing T type cable contact 9.As Fig. 4,5,6, hook 11 is formed by regulating nut 8, base 6, return spring 7 and support 17, the back first half of base 6 has certain plane inclined, and having a hole, connecting bolt 10 is equipped with in this hole, is used for fixing at the drop switch lower end, return spring 7 is equipped with in the top, front side of base 6, return spring 7 be used for guaranteeing T type cable touch 9 with the hook 11 power sizes, support 17 middle parts have a notch, are used for placing T type cable contact.As Fig. 7, cable end is by T type cable contact 9, sealing ring 14, and end socket cover 15 is formed, and T type cable contact 9 is connected with three single-phase terminations of high-tension cable 16, and sealing ring 14 is connected with the end of end socket cover 15 with high-tension cable 16.

During practical operation such as Fig. 8, holder fork 12 is enclosed within the top of insulating rod 13, is fixed up with valve 5, the people holds to insulate and 13 operates.Earlier T type cable contact 9 is placed in the middle part notch of U type carriage 1 in the holder fork 12, provoke the return spring of linking up with in 11 7 with the roller 2 in the holder fork 12, allow T type cable contact 9 enter in the notch of hook 11 medium-height trestles 17, unclamp roller 2 again, return spring 7 tightly suppresses T type cable contact 9, connects cable and finishes.Unload the cable order and connect the cable reversed in order, can unload cable operated according to opposite order.

Connect high-tension cable or unload high-tension cable and carry out choosing out under the drop switch situation with the utility model, thereby needn't stop whole transmission line, can freely be connected or unload cable or carry out the phase sequence adjustment, have saving of work and time, safe and reliable, advantage such as easy to use.The utility model is transformed slightly, can hang two even three cables and work simultaneously on a hook, is specially adapted to high-tension apparatus and moves frequent units such as mine.
