A little parts are standard component, can be chosen as needed when in use.
The process being operated using this tensioning fixing device is as follows：Support platform, tensioning support base, jack is solid
Determine bearing and anchor chain is fixed shackle and fixed by design attitude progress welded and installed；With steel wire rope epoxy resin glue by composite rope
Together with the steel wire rope of the heart is cast in composite rope steel wire rope socket；Detained with Kent and steel wire rope socket is connected with D type shackles, by D
Type shackle is connected with sliding chain cable fairlead；Work anchor chain is installed to anchor chain fixed and unload and buckle, and work anchor chain is sequentially passed through into cunning
Dynamic chain cable fairlead, fixed chain cable fairlead, screw stopper, then be connected with tensioning rod iron D type structures；The handwheel of rotating screw chain stopper,
Two locking arms of screw stopper are unclamped；Stretch-draw jack is installed on stretch-draw jack hold-down support, blending bolt is solid
It is fixed；Tensioning rod iron is passed through from stretch-draw jack, stretch-draw jack hold-down support central through hole, T-shaped threaded portion installation safety
Nut, fine thread portion installation tension-compression sensor and tensioning rod iron D type joints；The position of adjustment Safety nut is located at tensioning thousand
Jin top cylinder upper end, operation stretch-draw jack hydraulic oil pump constantly lifts stretch-draw jack oil cylinder, while continuous observation tension and compression pass
Sensor reading, until composite rope pulling force reaches design load.
If stretch-draw jack oil cylinder stroke has been at the end, and composite rope stretching force also backlog demand, rotating screw stop
The handwheel of chain device, closed and locked arm, installation locking pad, and according to the relative position of lock washer and locking arm, it is appropriate to be encased inside
The adjust pad of quantity, then stretch-draw jack is resetted, by tensioning rod iron D type joints and a section work nearest apart from lock washer
It is connected as anchor chain, lifts stretch-draw jack oil cylinder again, take out adjust pad and lock washer, open locking arm, continues tensioning
Composite rope, until composite rope stretching force meets to require.
After composite rope stretching force reaches design load, the handwheel of rotating screw chain stopper, closed and locked arm, installation locking pad
Piece, and according to the relative position of lock washer and locking arm, be encased inside an appropriate number of adjust pad, reset stretch-draw jack, tear open
Lower tensioning rod iron, stretch-draw jack, complete the tensioning and fixation of composite rope.
During operation maintenance, as the stretching force of composite rope has exceeded design load, first stretch-draw jack oil cylinder can be risen,
Tensioning rod iron D type joints are connected with a section work anchor chain nearest apart from lock washer again, stretch-draw jack oil cylinder is lifted, takes
Go out adjust pad and lock washer, open locking arm, reduce stretch-draw jack oil cylinder, until composite rope stretching force meets to require,
The handwheel of rotating screw chain stopper, closed and locked arm, installation locking pad, and according to the relative position of lock washer and locking arm
Put, be encased inside an appropriate number of adjust pad, fix work anchor chain.
During operation maintenance, as the stretching force of composite rope is less than design load, can by tensioning rod iron D type joints with apart from lock
The nearest section work anchor chain of tight pad is connected, and lifts stretch-draw jack oil cylinder, takes out adjust pad and lock washer, opens lock
Tight arm, stretch-draw jack oil cylinder is continued to lift up, until composite rope stretching force meets to require, rotation hand wheel, closed and locked arm, installation
Lock washer, and according to the relative position of lock washer and locking arm, be encased inside an appropriate number of adjust pad, fix work anchor
Chain, stretch-draw jack is resetted, tensioning rod iron, stretch-draw jack is pulled down, completes the tensioning and fixation of composite rope.
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited thereto,
Any one skilled in the art the invention discloses technical scope in, technique according to the invention scheme and its
Inventive concept is subject to equivalent substitution or change, should all be included within the scope of the present invention.
