Abstract
The utility model discloses a lead falling protector. The lead falling protector comprises a falling protector with a housing, a suspension hook is arranged in the top of the housing of the falling protector, and a steel wire outlet and a sealable suspension hook are arranged in the bottom of the housing of the falling protector, wherein the sealable suspension hook is connected with the lower end of a steel wire. The lead falling protector of the utility model has the advantages of light weight, simple structure, convenient for carrying and easy for installation. When a lead falls suddenly, the falling protector is tightened and does not move, thereby having protective effects; thus, the lead falling protector can effectively prevent the lead from falling off when an insulator of a high-voltage transmission line is replaced.
Description
Technical field
The utility model relates to power industry to be safeguarded, is specifically related to prevent when changing high-voltage transmission line insulator the wire anti-falling protection device that wire falls.
Background technology
Insulator is a kind of special insulation control, plays an important role in ultra-high-tension power transmission line.Insulator plays two basic roles in ultra-high-tension power transmission line, i.e. support wire and prevent that electric current from returning ground.Some insulator damages to be needed to change, and in the work of changing insulator, may produce wire and fall, and cause the circuit broken string of falling the tower whole time.Particularly single insulator string more will be carried out the safeguard measure of anti-wire dropping.Generally be fixed on the steel wire cover on the cross-arm of tower bar by the end with chain block, the other end is fixed on shackle and prevents wire dropping on the wire.
The utility model content
The purpose of this utility model is to provide a kind of wire anti-falling protection device that prevents wire dropping, and it is simple in structure, and is easy to use and be easy to install.
The purpose of this utility model realizes by following scheme:
A kind of wire anti-falling protection device comprises the chlamydate catching device of tool, and the catching device cover top portion is provided with suspension hook, the sealed suspension hook that the catching device outer casing bottom is provided with the steel wire outlet and is connected to the steel wire lower end.
Preferably, the described suspension hook that seals is band insurance card suspension hook or shackle.
The diameter of described catching device shell can be 20-30cm; Be preferably 25cm.
Preferably, the catching device shell is aluminium alloy.
Described steel wire diameter can be 0.15-0.25cm; Be preferably 0.2cm.
Wire anti-falling protection device of the present utility model has lightweight, simple in structure, is easy to carry and easy-to-install advantage.When wire descended suddenly, catching device will tighten up motionless playing a protective role.When changing high-voltage transmission line insulator, can prevent effectively that wire from falling.
Description of drawings
Fig. 1 is the schematic diagram of wire anti-falling protection device of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, describe content of the present utility model in detail.
As shown in Figure 1, wire anti-falling protection device of the present utility model comprises the chlamydate catching device 1 of tool, and the catching device cover top portion is provided with suspension hook 2, the sealed suspension hook 4 that the catching device outer casing bottom is provided with the steel wire outlet and is connected to steel wire 3 lower ends.Suspension hook can be sealed and band insurance card suspension hook or shackle can be.The diameter of catching device shell can be 20-30cm, is preferably 25cm.The material of catching device shell can be aluminium alloy.Steel wire diameter can be 0.15-0.25cm, is preferably 0.2cm.
When shaft tower 7 is changed insulator 5, climb up shaft tower 7 by the operating personnel, the suspension hook 2 of wire anti-falling protection device is hung over the pre-position of the cross-arm of shaft tower 7, then the slow stretching steel wire 3, can seal suspension hook 4 and be installed on the wire 6.Under the effect of catching device 1, steel wire 3 is in half nervous state; In case wire 6 falls, steel wire 3 speed of pulling out is obviously accelerated, and catching device 1 is with automatic locking, and the length that steel wire stretches is no more than 0.2m, so that wire 6 is supported and suspended by wire anti-falling protection device, and can not continue to fall.After having changed insulator 5, the weight of wire 6 is supported by insulator 5, and wire anti-falling protection device can automatically restore to normal operating conditions because load is removed.Can seal suspension hook 4 and remove from wire 6, steel wire 3 in catching device 1, unloads with suspension hook 2 the automatic recovery and gets final product from the cross-arm of shaft tower 7.
