The device special for laying the underwater cable has the advantages that the underwater cable can be draught by only dismounting the base at the dragging stage of the underwater cable, the underwater cable can be fixed and installed through sleeving the base on the lower shell and then fixedly installing the base on a top flange of a J-shaped pipe or I-shaped pipe in an installing site when the underwater cable is needed to be installed and fixed after the dragging, thus, the construction operation efficiency of the underwater cable is increased, and meanwhile, the construction difficulty and strength are also reduced.
Description
Technical field
The present invention relates to a kind of laying apparatu of cable, relate in particular to a kind of cable under water and lay isolated plant.
Background technology
The laid processes of cable comprises traction and anchoring under water; The mode that the traction of cable under water at present adopts comparatively coarse metal net knotting to tighten mostly; Be similar to the traction of overland cable, the untwisting slippage takes place easily in this draw-gear in distraction procedure, cause whole under water cable sink under water; Give to lay to salvage and bring very big difficulty; And this draw-gear can't seal the termination of cable under water, but needs under water the termination of cable carry out other encapsulation process to prevent into water, has increased extra work intensity to cable laying operation.After the traction of cable is under water accomplished, need under water an end of cable that anchor system is installed cable is under water fixed, to guarantee the stability of cable work under water.But the traction of cable under water at present and anchoring are 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 provides and a kind ofly improves the construction operation efficient of cable under water and in operation process, can lay isolated plant to the cable under water that cable under water carries out effective water-tight.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: cable lays isolated plant under water; Comprise traction element and anchorage part; Described traction element comprises upper shell, lower house and drawing head; Described anchorage part comprise base be used for fixing the anchoring assembly of cable under water, 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; Be provided with the inner chamber that is used to pour into waterproof gasket cement between described lower house and the described anchoring assembly; Described base sheath is connected on the described lower house, and described drawing head fixed seal connection is bolted with the lifting screw on the described drawing head on described upper shell.
Described anchoring assembly comprises the push pedal of pressing plate, ring flange and back taper; Solid and right embracing admittedly embraced on a left side that is provided with back taper in the described push pedal; Be connected through bolt between described push pedal and the described pressing plate; Be connected through bolt between described ring flange and the described pressing plate, described pressing plate is provided with first central through hole, and described ring flange is provided with second central through hole coaxial with described first central through hole; Be set with top cover labyrinth on described second central through hole; Described lower house is fixedly connected with described flangeseal respectively with upper shell, and described lower house is provided with three central through hole coaxial with described first central through hole, is set with lower sealing cover on described the 3rd central through hole.
A described left side is embraced solid and the described right side is embraced and is provided with bolt between solid, can prevent a left side embrace solid and right embrace solid between mutual dislocation, and can make a left side embrace solid and right armful to tighten up on the outer surface of holding cable under water tightly tightly.
Described lower house and upper shell are tightly connected through sealing ring respectively and between the described ring flange.
Described drawing head and described upper shell bolt are tightly connected through sealing ring between described drawing head and the described upper shell.
Described base is made up of two semiorbicular decks, makes things convenient for base to be installed on the 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, just can realize the traction of cable under water as long as base pulled down, in the time need installing and fixing under water cable after the traction completion; As long as base is set on the lower house; Then base is fixedly installed on the top flange of J-shaped pipe or I shape pipe of mounting points and can realizes the fixed installation of cable under water, improved the construction operation efficient of cable under water, reduced difficulty of construction intensity simultaneously again; And, in inner chamber, pour into waterproof gasket cement owing to be provided with inner chamber between lower house and the anchoring assembly, and can realize the sealing of cable-end portion under water, prevent that cable is intake under water in the process of traction; In addition, fix cable under water, the material of cable armour is not under water required, and whole device volume is less, use flexibly with the anchoring assembly in this device.
