Secondary cable laying method at a kind of corner location, comprising the following steps:
Step 1, assembly and adjusting:
Step 1.1, it is arranged and turns to roller bearing, rotation roller frame:
It takes out the installation pedestal and places it with the upward posture of the first inserted link, then successively by underlying turn
Dynamic roller frame, is set on the central rotating shaft rotation roller frame for turning to roller bearing, being located above, and makes the cable of a pair of of rotation roller frame
The close setting of roller frame, and the rolling longitudinal axis of a pair of of rotation roller frame is respectively positioned on rear, then by torsionspring one end with it is corresponding
Rotation transverse arm connects and the other end is plugged in corresponding torsional spring jack, finally successively screws in two angle positioning bolts corresponding
Angle location hole, it is temporarily fixed to rotate roller frame；
Step 1.2, fixed active block stop:
The active block stop is set on first inserted link, is inserted into spring jack and by first by metal thin bar
Pressure spring lower end dials up, until first pressure spring bottom is higher than the caging bolt, then revolves the caging bolt
Enter in the spring jack, extract metal thin bar, first pressure spring lower end is resisted against below the caging bolt；
Step 2, it installs:
Step 2.1, the second inserted link of grafting:
Two the second inserted links are successively taken out from accommodating in slot, are then inserted into fixed stop respectively, in active block stop, most
The second inserted link is inserted into wall afterwards；
Step 2.2, rotation roller frame is adjusted:
The angle positioning bolt is removed, a pair of of rotation transverse arm of torsionspring driving is resisted against turning two sides；
The long positioning bolt is dismantled, then along the rotation transverse arm sliding cable roller frame to suitable position, and
The rotation of long positioning bolt is located in suitable length positioning hole by this；
Step 3, it is laid with cable:
By cable pass through any cable roller frame threading hole, then around the turnbarrel bent after be then passed through it is another
The threading hole of cable roller frame；
Step 4, cable is pulled:
The cable is acted on pulling force F to move it, the cable in the cable roller frame with the ball, rolling
The longitudinal axis is in rolling contact, and the cable is in rolling contact with the turnbarrel, substantially reduces the mobile resistance of the cable, is avoided straight
It connects and pulls cable to cause to wear in corner；
When the pulling force F and metope are not parallel, the work of the cable roller frame far from wall is given in cable outlet one end
The cable roller frame is acted on component F1, so that the cable roller frame and rotation transverse arm are around the central rotating shaft to far from wall
Direction rotation, the rotation roller frame direction further decrease the cable and roll the longitudinal axis, center turns close to cable outlet direction
Resistance between axis.
The step 1 is further comprising the steps of: step 1.3, adjust torsionspring damping:
The position of a pair of of cable roller frame is adjusted until a pair of cable roller frame will not generate interference when rotating a pair of of rotation roller frame；
It is relatively rotated using the central rotating shaft as axle center relative to by a pair of rotation roller frame, adjusts the torsion of the torsionspring
Number is enclosed, and then adjusts the damping of torsionspring, adjusts the size that rotation roller frame is pulled to power required for deviateing corner.
Secondary cable laying method at a kind of wall locations, it is characterised in that:
Step 1, assembly and adjusting:
Step 1.1, it is arranged and turns to roller bearing, rotation roller frame:
It takes out the installation pedestal and places it with the upward posture of the first inserted link, then successively by underlying turn
Dynamic roller frame, is set on the central rotating shaft rotation roller frame for turning to roller bearing, being located above, and makes the cable of a pair of of rotation roller frame
The close setting of roller frame, and the rolling longitudinal axis of a pair of of rotation roller frame is respectively positioned on rear, then by torsionspring one end with it is corresponding
Rotation transverse arm connects and the other end is plugged in corresponding torsional spring jack, finally successively screws in two angle positioning bolts corresponding
Angle location hole, it is temporarily fixed to rotate roller frame；
Step 1.2, fixed active block stop:
The active block stop is set on first inserted link, is inserted into spring jack and by first by metal thin bar
Pressure spring lower end dials up, until first pressure spring bottom is higher than the caging bolt, then revolves the caging bolt
Enter in the spring jack, extract metal thin bar, first pressure spring lower end is resisted against below the caging bolt；
Step 2, it installs:
Step 2.1, the first inserted link of grafting:
The installation pedestal was fallen, so that the first inserted link is towards front and is inserted into completion fixation in wall；
Step 2.2, adjustment rotation roller frame 3:
It successively screws off angle positioning bolt and adjusts the angle of corresponding rotation transverse arm, so that the not-go-end of the rotation transverse arm is higher than
Then the central rotating shaft is successively fixed angle positioning bolt；
The long positioning bolt is dismantled, then along the rotation transverse arm sliding cable roller frame to suitable position, and
The rotation of long positioning bolt is located in suitable length positioning hole by this；
Step 3, it is laid with cable:
Cable is sequentially passed through to the threading hole of a pair of of cable roller frame, the cable is located above the turnbarrel；
Step 4, cable is pulled.
Beneficial effects of the present invention:
The secondary cable protective cradle can provide at least two different mounting means:
Mode one: it the installation pedestal is arranged with the upward posture of the first inserted link and passes through the second inserted link is fixed in
Cable is passed through threading hole and is sticked on outer wall of the turnbarrel far from turning by corner location, avoids rubbing with turning
Damage cable.
Mode two: it the installation pedestal is arranged with the forward posture of the first inserted link and passes through the first inserted link is fixed in
Wall locations；Cable is passed through into threading hole and is sticked on outer wall of the turnbarrel far from ground, cable is lifted out
Ground is avoiding cable from falling on the ground due to too long, with ground friction.
The distance of the adjustable cable roller frame distance center shaft of secondary cable protective cradle so that cable roller frame with
There are enough distances that can wear enough cables between central rotating shaft.
The damping of the secondary cable protective cradle also adjustable torsionspring first adjusts the position of a pair of of cable roller frame
It avoids it from hindering the relative rotation of a pair of of rotation roller frame, then relatively rotates the damping that a pair of of roller frame adjusts the torsionspring,
Allow in one the embodiment described of mode: the torsionspring provides suitable twisting resistance and cable roller frame is fitted in
Corner location, and when pulling cable with the not parallel dynamics of turning plane with one, the cable can be by cable roller frame
It to the position pulling far from turning metope and then keeps with cable direction close to unanimously, pulls wire cable is more smooth light under the state
Just.
