Abstract
The utility model belongs to the technical field of clamps, and particularly discloses a principal material clamp for the principal material replacement of power angle tower pulling legs. The utility model has the technical scheme that the principal material clamp comprises a front angle plate and a rear angle plate with the same shape to the front angle plate, screw holes are arranged on the front angle plate and the rear angle plate, a hook plate perpendicular to the front angle plate is arranged at the front end of the front angle plate, a hook is arranged at the top end of the hook plate, and the front angle plate and the rear angle plate are fixed on a principal material via screws so that the front angle plate and the rear angle plate can be fixed more firmly. When a defective principal material is replaced, power off is not required, influences caused by power off on the power grid and the production and living of power utilization customers are avoided, the procedures of wire falling, wire tensioning and the like are reduced, and the replacement time is greatly shortened.
Description
Technical field
The utility model belongs to the jig technical field, and particularly a kind of electric power angle tower draws leg main material replacing method and special-purpose main material jig.
Background technology
The electric power angle tower draws leg master material in use, and the influence owing to receiving reasons such as wind-force, corrosion, circuit freeze makes the electric power angle tower draw leg master material to rupture easily, must in time change, if untimely replacing can cause potential safety hazard to the circuit operation.It is exactly earlier with line outage that present replacing electric power angle tower draws the main method of leg master material; Anchor support both sides tangent tower is carried out anchor, then with the leading of anchor support, ground wire all from aerial pine to ground, former iron tower tower material is removed, more renew and could accomplish the tower material at hanging wire behind the tower material and change task.Need 2 days power off time so approximately, power off time is long, and workload is big, needs the human and material resources of labor, and electric network reliability also is greatly affected.
Summary of the invention
The technical problem that the utility model solves just provides a kind of easy accessibility, realizable force angle tower that pulling force is big and draws the leg main material replacing with main material jig.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: gusset and the back gusset identical with this preceding gusset shape before comprising; Before said, have screw on gusset and the said back gusset; Said anterior angle front edge of board be provided with said before the vertical hanger plate of gusset, be provided with hook on the top of said hanger plate.
The electric power angle tower that the utility model provided draws the leg main material replacing with main material jig; Compare with prior art and to have the following advantages: because gusset and the back gusset identical before comprising with this preceding gusset shape; Before said, have screw on gusset and the said back gusset, said anterior angle front edge of board be provided with said before the vertical hanger plate of gusset, be provided with hook on the top of said hanger plate; Preceding gusset and back gusset are fixed on the main material through screw rod, fixing more firm.
Description of drawings
Fig. 1 is for changing the sketch map of defective master material method;
Fig. 2 is the structural representation of main material jig.
The specific embodiment
Draw leg main material replacing method and special mould clamp to do further detailed description below in conjunction with accompanying drawing and specific embodiment to the electric power angle tower that the utility model provided.
As shown in Figure 1, for changing the sketch map of defective master material method, the electric power angle tower that the utility model provides draws leg main material replacing method, and this method comprises the following steps:
The first step is installed earth anchor and temporary guy
Outer 5m-7m place around defective master material 1 basis; Symmetry is uniformly distributed with buries 4 7t-8 t level earth anchors 2 underground, above earth anchor 2, will stack the above mound of 300mm and jam on reality, is not less than the China fir bar 4 about 110mm, length 1.3-1.8m in the footpath slightly in the 3 inboard colligations of the main material above the defective master material 1; Four temporary guys 5 are set in the inboard of iron tower main material; Temporary guy 5 upper end colligations are on China fir bar 4, and operating personnel must stand in the inboard of iron tower main material, transmit rope also about the iron tower inboard;
Second step, the tension temporary guy
In the 3rd step, remove the foundation to protect cap
Remove damage and draw leg foundation to protect cap;
In the 4th step, the column foot jig is installed
Remove damage and draw leg outer side two foot bolt symmetrically, and the column foot jig 7 that will have a link 6 is fixed on the stone bolt position;
In the 5th step, main material jig is installed
The main material jig 9 that has hook 8 is installed on the iron top of embracing in defective master material 1 upper end;
In the 6th step, install two cover tensioning tools
On the hook 8 of main material jig 9, pass steel rope sleeve 13, below steel rope sleeve 13, hang up chain block 14, the lower end of this chain block 14 hangs on the link 6 of column foot jig 7;
In the 7th step, remove the 8 theftproof joint bolts in main material upper end
After straining chain block to suitable rate of tension, remove defective master material 18 theftproof joint bolts topmost, replace to ordinary couplings bolt and fastening good simultaneously in dismounting by root;
In the 8th step, continue to remove other 8 theftproof joint bolts of main material upper end
Continue to remove the remaining 8 theftproof joint bolts in defective master material 9 upper ends; Replace to the ordinary couplings bolt simultaneously; This ordinary couplings bolt is not fastening, and slowly loosen fastening 8 good bolts this moment, and observes the relative motion situation of the main material in top at any time; Prevent that it from upwards sliding, and adjusts chain block in case of necessity;
The 9th step, other bolts of dismounting defective master material 1
After treating that defective master material 1 upper end track bolt all unclamps, and the main material position of defective master material 1 upper end do not change, and observe each stress point all stable after, begin to remove other anti-theft bolt that is connected on the defective master material;
In the tenth step, more renew main material
Correct position above defective master material 1 suspension crane rope, unload defective master material after, new main material and oblique material are installed, and with all bolton to the moment of torsion standard;
In the 11 step, remove the replacing instrument
Remove main material jig, steel rope sleeve, chain block, column foot jig, earth anchor and temporary guy.When changing defective master material, do not need to have a power failure, to avoid the influence that electrical network and electricity consumption client productive life caused because of having a power failure, and reduced operations such as the line of fall, stringing, the replacing time shortens greatly.
As shown in Figure 2; Be the structural representation of main material jig, before this main material jig 9 comprises gusset 91 with the identical back gusset 92 of these preceding gusset 91 shapes, on preceding gusset 91 and back gusset 92, have screw 93; Be provided with the hanger plate 94 vertical at the front end of preceding gusset 91 with preceding gusset 91; Be provided with hook 95 on the top of hanger plate 94, preceding gusset 91 and back gusset 92 are fixed on the main material through screw rod, fixing more firm.
