Description
Technical field
The present invention relates to a kind of laying apparatu of cable, relate in particular to a kind of Special device for laying underwater cable.
Background technology
The laid processes of underwater cable comprises traction and anchoring, the mode that the traction of underwater cable at present adopts comparatively coarse metal net cover knotting to tighten mostly, be similar to the traction of overland cable, the untwisting slippage easily occurs in this draw-gear in distraction procedure, cause whole underwater cable to sink under water, give to lay to salvage and bring very large difficulty, and this draw-gear can't be sealed the termination of underwater cable, but the termination of underwater cable need to be carried out to other encapsulation process to prevent into water, increased extra work intensity to cable laying operation.After underwater cable has drawn, need an end installation anchor system of cable under water to be fixed underwater cable, to guarantee the stability of underwater cable work.But the at present traction of underwater cable and anchoring is two cover systems independently, need when construction, install and use respectively, and this has increased difficulty of construction and has laid intensity, and the while has also been reduced operating efficiency.
Summary of the invention
Technical problem to be solved by this invention is to provide and a kind ofly improves the construction operation efficiency of underwater cable and can carry out to underwater cable the Special device for laying underwater cable of effective sealing waterproof in operation process.
The present invention solves the problems of the technologies described above adopted technical scheme: Special device for laying underwater cable, comprise traction element and anchorage part, described traction element comprises upper shell, lower house and drawing head, described anchorage part comprises base and for the fixing anchoring assembly of underwater cable, described upper shell and lower house are sealedly and fixedly connected with described anchoring assembly respectively, described anchoring assembly is positioned at described lower house, between described lower house and described anchoring assembly, be provided with for pouring into the inner chamber of waterproof gasket cement, described base sheath is connected on described lower house, described drawing head fixed seal connection is on described upper shell, be bolted with the lifting screw on described drawing head.
Described anchoring assembly comprises pressing plate, the push pedal of ring flange and back taper, be provided with left holding-solid and the right holding-solid of back taper in described push pedal, between described push pedal and described pressing plate, be bolted to connection, between described ring flange and described pressing plate, be bolted to connection, be provided with the first central through hole on described pressing plate, be provided with second central through hole coaxial with described the first central through hole on described ring flange, be fixedly installed top cover labyrinth on described the second central through hole, described lower house is fixedly connected with described flangeseal respectively with upper shell, be provided with three central through hole coaxial with described the first central through hole on described lower house, be fixedly installed lower sealing cover on described the 3rd central through hole.
Be provided with bolt between described left holding-solid and described right holding-solid, can prevent mutual dislocation between left holding-solid and right holding-solid, and can make left holding-solid and right holding-solid hold tightly tightly on the outer surface of cable under water.
Described lower house and upper shell are tightly connected by sealing ring respectively and between described ring flange.
Described drawing head and described upper shell bolt, be tightly connected by sealing ring between described drawing head and described upper shell.
Described base is comprised of two semiorbicular decks, facilitates floor installation to lower house.
Compared with prior art, advantage of the present invention is because this laying apparatu comprises traction element and anchorage part, and traction element and anchorage part interconnect, during use, traction stage of cable under water, as long as base is pulled down to the traction that just can realize underwater cable, while needing to install fixedly underwater cable after traction completes, as long as base is set on lower house, then base is fixedly installed to the fixed installation that can realize underwater cable on the top flange of the J-shaped pipe of mounting points or I shape pipe, improved the construction operation efficiency of underwater cable, reduced again difficulty of construction intensity simultaneously, and owing between lower house and anchoring assembly, being provided with inner chamber, pour into waterproof gasket cement in inner chamber, can realize the sealing of underwater cable end, prevent underwater cable the traction process in intake, in addition, with the anchoring assembly in this device, fix underwater cable, the material of underwater cable armour is not required, and whole device volume is less, use flexibly.
