the utility model provides a cable intermediate head protection device for support cable intermediate head sets up in the cable shaft, be equipped with the cross arm angle bar in the cable shaft, including support frame and explosion-proof box, the cable intermediate head is used explosion-proof box parcel protection, the support frame is used for supporting the cable intermediate head in including explosion-proof box and explosion-proof box, the both sides of support frame are equipped with the pillar, the pillar is fixed in on the cross arm angle bar in the cable shaft.
Preferably, the support frame is a latticed bridge frame, and the latticed bridge frame with a proper size is selected, so that the support frame not only can support a cable middle joint comprising the explosion-proof box, but also can solve the problem of silt deposition caused by the traditional adoption of plate or tubular materials.
Preferably, the length of support frame is longer than the length of explosion-proof box, and the degree that cable intermediate head atress pull is damaged can be reduced to the length of reserving.
Preferably, the supporting columns are bound and fixed on cross arm angle iron in the cable shaft by using bare copper wires.
Preferably, the support frame adopts a mechanism made of angle steel, channel steel or round steel, and the support frame is made of angle steel, channel steel or round steel with small area, so that the problem of corrosion can be avoided.
Preferably, a buffer layer is arranged between the explosion-proof box and the cable intermediate joint, and the buffer layer is filled with a buffer material, so that the situation that the cable intermediate joint is damaged due to collision between the explosion-proof box made of hard materials and the cable intermediate joint under the oscillation condition can be avoided.
Compared with the prior art, the utility model discloses technical scheme's beneficial effect is:
through choosing the latticed crane span structure of suitable size for use, can the bearing include the cable intermediate head of explosion-proof box, can solve the siltation silt problem that tradition adopted board or tubular material again, reduce the degree that cable intermediate head atress broke through reserving length, make the support frame with the angle steel of small area, channel-section steel or round steel simultaneously and avoid the corrosion problem, set up the buffer layer and avoid making cable intermediate head receive the damage because of the oscillation.
