Cross over net
Technical field
The present invention relates to the unwrapping wire instrument that do not have a power failure in a kind of power circuit process of construction, relate in particular to a kind of leap net.
Background technology
Present stringing at first will have a power failure to the electric wire below the circuit, will cause a lot of potential safety hazards like this, and the personnel that use are more, and so very inconvenience is also dangerous.
Summary of the invention
The purpose of this invention is to provide a kind of leap net, can under situation about not having a power failure, carry out setting up of electric wire, and can guarantee safety.
For realizing above-mentioned purpose, the technical scheme that the present invention adopts is:
A kind of leap net comprises rope and sleeve pipe, it is characterized in that: rope is divided into three, and the mounting sleeve of restricting between three is installed pulley on the iron tower cross-arm, and the two ends of rope are all passed pulley and connected earth anchor.
According to described leap net, it is characterized in that: said iron tower cross-arm is installed in brandreth.
According to described leap net, it is characterized in that: said rope and sleeve pipe are positioned at the top that is surmounted power line.
According to described leap net, it is characterized in that: said rope twines out the collar, and the two ends of sleeve pipe are connected on the collar.
According to described leap net, it is characterized in that: said rope is the Di Nima rope, and sleeve pipe is the epoxy resin pipe.
Advantageous effect of the present invention is: utilize Di Nima rope unwrapping wire can realize the leap payingoff construction that do not have a power failure, the leap frame of comparing is in the past set up situation, and this scheme saves floor occupying area, and is safe and reliable, and practices thrift effectively the unwrapping wire time.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is described further:
Structure of the present invention is as shown in Figure 1, and a kind of leap net comprises rope 5 and sleeve pipe 6, it is characterized in that: rope 5 is divided into three, and rope 5 mounting sleeves 6 between three are installed pulley 3 on the iron tower cross-arm 8, and the two ends of rope 5 are all passed pulley 3 and connected earth anchor 2.According to described leap net, it is characterized in that: said iron tower cross-arm 8 is installed in brandreth 4.According to described leap net, it is characterized in that: said rope 5 is positioned at the top that is surmounted power line 1 with sleeve pipe 6.According to described leap net, it is characterized in that: said rope 5 twines out the collar 7, and the two ends of sleeve pipe 6 are connected on the collar 7.According to described leap net, it is characterized in that: said rope 5 is the Di Nima rope, and sleeve pipe 6 is the epoxy resin pipe.
Use principle of the present invention is as shown in Figure 1: in the both sides that surmounted power line 1 brandreth 4 is installed; The height of brandreth 4 is higher than and is surmounted power line 1; The two ends of rope 5 are fixed on the earth anchor 2, and earth anchor 2 is fixed on the ground, and the ew line that need set up passes above sleeve pipe 6; So just can when not breaking off the electricity that is surmounted power line 1, carry out work, sleeve pipe 6 be positioned at surmounted power line 1 above.This construction plan material requested is: the Di Nima of the band collar 7 of 3 enough custom-mades of intensity rope, according to the required pulley 3 of spanning length required epoxy resin bushing 6, unwrapping wire and the collar 7 of joint sleeve 6.Epoxy resin bushing 6, the Di Nima rope 5 enough with intensity passes, and both sides hang up U-loop or the link that connects usefulness.It is 3 meters that epoxy resin bushing 6 is generally got length.Span between two iron towers 4 is probably about more than 300 meters, and required every enlightening Nima rope 5 is about 400 meters, wherein hangs down 50 meters behind rope to the iron tower cross-arm 8 approximately so that fixing rope.The rope collar 7 per 1 meter do one.During unwrapping wire; On iron tower cross-arm 8, hang up and put the required pulley of rope 3; The workmen is after rope is let slip; Understand institute cross-line road after the general distance of iron tower 4, by the general distance of being striden the ready-made epoxy resin bushing 6 of customization is installed on Di Nima rope sling ring 7, make epoxy resin bushing 6 be tiled in top, institute cross-line road by workmen on the tower.Rope strenuous exercise not can be provided with four interim backguys on the two enlightening Nimas ropes 5 in the outside when guaranteeing construction.
The present invention utilizes Di Nima rope unwrapping wire can realize the leap payingoff construction that do not have a power failure, and the leap frame of comparing is in the past set up situation, and this scheme saves floor occupying area, and is safe and reliable, and practices thrift effectively the unwrapping wire time.
Embodiment recited above describes preferred implementation of the present invention; Be not that design of the present invention and protection range are limited; Under the prerequisite that does not break away from design concept of the present invention; Common engineers and technicians make technical scheme of the present invention in this area various modification and improvement all should fall into protection scope of the present invention.
