Abstract
The invention discloses a low piezoelectric bar centralizing bracket. Support legs 1 and a hanging ring 3 are arranged at the lower end of an outer pipe 4; the support legs 1 are made of round steel; and supporting angle iron 2 is welded on the supporting legs 1. A fixed pulley 5 is arranged outside the top end of the outer pipe 4 through a bracket 9; a liftable inner pipe 6 is sleeved in the outer pipe 4; the surface of the inner pipe 6 is provided with a longitudinal notch 8; a steel wire rope 10 is arranged at the lower end inside the inner pipe 6 through a fixed pin 11; the other end of the steel wire rope 10 is pulled out from the longitudinal notch 8 and wound around the fixed pulley 5; and a clamp 7 is arranged at the top end of the inner pipe 6. When the bracket is used for centralizing an inclined piezoelectric bar, the support legs 1 are driven underground, the clamp 7 is in contact with the piezoelectric bar, two ends of a hand-drive block are respectively tied on the hanging ring 3 and wound around the steel wire rope 10 of the fixed pulley 5, and the steel wire rope 10 is drawn by pulling the hand-drive block to drive the inner pipe 6 to raise, so that the inclined piezoelectric bar can be gradually centralized by using the clamp 7 at the top end of the inner pipe 6.
Description
Technical field
The invention belongs to electric power conveying technology field, particularly the low piezoelectric bar centralizing technology.
Background technology
The low-voltage overhead line road is positioned at cottage area mostly, and the tunnel is narrow.Behind the low pressure power-steeling preventing electric reform, the souvenir that is positioned at the resident house is originally transformed hung on the electric pole or follow closely on resident's external wall of house.Each side house lead in number of lines difference of electric pole causes electric pole in the suffered tension force difference of all directions.Cause electric pole to tilt to different directions.The method set upright of electric pole was used crane or was used manpower to drag in the opposite direction with big rope in the past.But most low tunnels, district of presenting a theatrical performance as the last item on a programme are narrower, and crane can't enter, and personnel can stand nowhere, and the electric pole of a lot of inclinations can't be set upright, the operation of band defective.
Summary of the invention
In order to solve the low piezoelectric bar centralizing problem, following technical scheme is proposed.
A kind of low piezoelectric bar centralizing bracket, its special character is in the lower end of outer tube leg and link to be installed, fixed pulley is installed in the outside, top of outer tube, the interior pipe that suit can free lifting in the outer tube, interior tube-surface has vertical breach, there is wire rope in inside lower end system at interior pipe, and the other end of wire rope is walked around fixed pulley after vertical breach is pulled out, and jig is installed on the top of interior pipe.
Can be plug-in mounting structure between outer tube and the leg, the diameter of leg be less than the external diameter of outer tube.Can earlier leg be driven underground so in use, then outer tube be inserted on the leg.
When using this low piezoelectric bar centralizing bracket to set upright the electric pole of inclination, the reciprocal soil that earlier electric pole tilted digs out, and reserves the space after electric pole is set upright.Then this support is placed on inclination one side of electric pole, leg is inserted underground, make in the pipe top jig closely contact with electric pole.Two ends with bottle gouard moved by hands tie up to link respectively and walk around on the steel wire rope head of fixed pulley in addition.By the pulling bottle gouard moved by hands, haulage cable, pipe rises in outer tube in driving, and gradually the electric pole that tilts is just being pushed up.
The present invention has following advantage
Use this to set upright the problem that support has solved low piezoelectric bar centralizing, save manpower, improved operating efficiency.
Description of drawings
Fig. 1 is the front view of embodiment, and Fig. 2 is partial enlarged drawing A, and Fig. 3 is partial enlarged drawing B, and Fig. 4 is the vertical view of embodiment, and Fig. 5 is the local C of amplification.
Embodiment
A kind of low piezoelectric bar centralizing bracket, leg 1 and link 3 are installed in the lower end of outer tube 4, and described leg 1 is made welding support angle bar 2 it on by round steel, the lower end of leg 1 (round steel) is pointed (so that being driven underground), and the diameter of leg 1 is less than the internal diameter of outer tube 4.Fixed pulleys 5 are installed by carriage 9 in the outside, the top of outer tube 4, the interior pipe 6 that suits can free lifting in the outer tube 4, and the external diameter of interior pipe 6 is less than the internal diameter of outer tube 4, so that interior pipe 6 free lifting in outer tube 4.Outer tube 4 by
The steel pipe of long 3000mm is made, interior pipe 6 by
The steel pipe of long 3000mm is made.Interior pipe 6 surfaces have vertical breach 8, by steady pin 11 wire rope 10 are installed in the inside lower end of interior pipe 6, and the other end of wire rope 10 is walked around fixed pulley 5 after vertical breach 8 is pulled out, and jig 7 is installed on the top of interior pipe 6.
Claims (1)
1. low piezoelectric bar centralizing bracket, it is characterized in that leg and link being installed in the lower end of outer tube, fixed pulley is installed in the outside, top of outer tube, the interior pipe that suit can free lifting in the outer tube, interior tube-surface has vertical breach, there is wire rope in inside lower end system at interior pipe, and the other end of wire rope is walked around fixed pulley after vertical breach is pulled out, and jig is installed on the top of interior pipe.
