In the construction of municipal engineering and house construction engineering, usually adopt large-scale construction equipment as crane and so on, and construction plant circumstance complication often, part construction plant and high-tension line close on.And the job specification of crane need when working to have determined certain radius of clean-up, when high-tension line is in radius of clean-up scope, might cause the electrion accident, and the probability that occurs accident when Job Operations personnel and high-tension line trend is the blind angle of vision is bigger, therefore, how avoiding big machinery and high-tension line to close in construction period causes security incident to become a urgent problem.
(3), utility model content:
The technical problems to be solved in the utility model is: at the prior art deficiency, provide a kind of simple in structure, cost is low, protection effect is good high voltage protection net.
The technical solution of the utility model:
A kind of high voltage protection net, contain insulation net bar and insulation nettle, the insulation net bar of a certain number of vertical setting is arranged in delegation, and the top of each net bar that insulate evenly is provided with a certain number of insulation rest, the insulation nettle is fixed by the insulation rest, and each insulate, and knot is linked to be an insulating protection net between the net bar.
The insulation nettle for lateral junction connects, or be vertical knot company between two insulation rests, or be oblique knot even; Insulation contains the draw-in groove of fixed insulation nettle on the rest, and the insulation rest is fixed on the insulation net bar by bolt or bayonet socket or viscose glue.
The lower end of insulation net bar is a tip, so that imbed underground, distances between the adjacent two insulation net bars are 3～6 meters, and the distances on the same insulation net bar between the adjacent two insulation rests are 0.5～1.5 meter, each rest that insulate apart from the length of the lower end of insulation net bar all greater than 3 meters.
Insulation net bar is a bamboo pole, or is rod, or is fiberglass rod; The material of insulation rest is plastics, or is high polypropylene; The insulation nettle is the rope made of hemp, or is nylon rope.
The number of insulation net bar is 4～15, and the number of the insulation rest on each insulation net bar is 5～15, and the diameter of insulation net bar is 50～100 millimeters, and the diameter of insulation nettle is 20～40 millimeters.
Continuously or the compartment of terrain on insulation net bar, cable rope is set, the number of cable rope is at least two, the end of cable rope is provided with and buries the ground cleek, bury the ground cleek imbed underground, cable rope is stretching, in case the high voltage protection net tilts.
Cable rope is 6～8 meters apart from the length of the lower end of insulation net bar, and the diameter of cable rope is 20～40 millimeters.
During actual the use, the high voltage protection net is installed in beyond the safe distance of high-tension line, during the medium-and-large-sized machinery of architectural process (as crane) work, in case the distance of arm and high-tension line is less than safe distance, the high voltage protection net will limit the motion of arm, thereby reach the purpose to the high-tension line security protection.
The beneficial effects of the utility model:
1, the utility model mainly is made up of insulation net bar and insulation nettle, and the insulation nettle is fixed by the insulation rest on the insulation net bar, and each insulate, and knot is linked to be an insulating protection net between the net bar, and therefore, it is simple in structure, cost is low.
2, the utility model has been filled up the domestic room of having stable political situation in the city and has been built in the construction engineering the blank aspect the high-tension line protection, and its protection effect is good, has ensured mechanical work personnel's safety, has improved operating efficiency indirectly, and dismounting is also very convenient, and is sturdy and durable.
