Background technology
In the work progress of great-leap-forward overhead transmission line, to use usually and cross over frame overhead leap, set up the leap frame according to the needs that the scene is crossed over from highway, railway, communication line or existing transportion wire road.Existing 35kV～220kV power circuit and electric railway do not have a power failure and cross over the leap frame that uses in the construction and can not regulate height; When the height not timing of being crossed over thing; Need set up the leap frame of differing heights; Adapting to the construction needs of different regions, not only waste of manpower, material resources, and also construction cost is higher; In addition, existing leap frame dismantling operation after construction finishes is loaded down with trivial details, the progress of influence construction.
Summary of the invention
The purpose of the utility model is to solve the problem of above-mentioned existence, and a kind of simple in structure, support safety, firm is provided, and height can freely regulated hoisting type live across frame.
For realizing above-mentioned purpose; The hoisting type live across frame of the utility model design; Comprise two-door of being arranged in juxtaposition or a plurality of two-door and the safety net that covers each two-door top of the trellis, wherein, form by two simple gate framves, the cross bar that is connected simple gate frame top for two-door; Said simple gate frame is made up of two vertical single poles and the crossbeam that is connected the single pole top, and four said two-door tops are connected with four angles of safety net respectively.
In technique scheme; Said single pole comprises base, be installed in first column on the base, be installed in first column upper end second column, be installed in the 3rd column on second column, be installed in the 4th column on the 3rd column, the bottom of said first column is equipped with hoist.
Further, the side of said the 4th column is equipped with the insulation cat ladder.
Further, be connected secondary rolling rope between the top of said the 4th column and the ground.
Further, the top of said the 4th column is connected with insulated tension pole.
Further, the one-level rolling rope that is connected with between the bottom of said the 3rd column and the ground.
Again further, said crossbeam is the round log of resin structure, and its two ends are equipped with the cylinder that contains nylon.
The hoisting type live across frame that the utility model provides; Bottom at insulated tension pole is equipped with hoist, in use can be according to the height of being crossed over thing, and the height of frame is crossed in adjustment in real time; Simple to operate; Whole leap shelf structure is stable firmly, and is simple in structure, can satisfy 35kV～220kV power circuit and electric railway well and not have a power failure and cross over the requirement of construction; Construction finishes, and whole leap frame is removed easily, and is easy to operate.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to specify.
As shown in Figure 1, hoisting type live across frame comprises two-door of being arranged in juxtaposition or a plurality of two-door and the safety net 7 that covers each two-door top of the trellis; Be made up of two simple gate framves, the cross bar 8 that is connected simple gate frame top for two-door, the simple gate frame is made up of two vertical single poles 1 and the crossbeam 10 that is connected the single pole top, and four tops of two-door are connected with four angles of safety net 7 respectively.
When the utility model supplies single line to pass through, can adopt two-door shelf structure, promptly two-door of 4 single pole compositions.Supply three-way above through the time, can specifically adopt multi-door shelf structure according to on-the-spot demands of different.The bottom of the base 13 and first column 1.1 is hinged; Be convenient to assembling; First column 1.1, second column 1.2, the 3rd column 1.3, the 4th column 1.4 are telescopic structure; Available manual hoist rises to the precalculated position with each column, manually is provided with self-locking device in the hoist, guarantees in the process of hoisting safe and reliable.Hoist 2 handle active forces meet the regulation of relative national standards less than 20N.Crossbeam 10 is the round log of resin structure, and two ends are installed and to be contained the nylon cylinder, and lead or pull rope can make round log roll during through round log, to reduce resistance.
In the specific embodiment,, measure the center line of simple gate frame according to newly-built line construction phase line direction.Require to confirm the distance in stake position and this power line sideline according to electric pressure of being crossed over power line and national regulation.In base and shaft location, and after the direction of definite insulating ladder, manual hoist, it is also fixing that one-level rolling rope is installed.Little arm, crossbeam, crossbeam retainer ring locking (can adopt No. 8 iron wires to make the ∞ font is fastened on following semi-ring) are installed.Tighten hoist steel wire rope set bolt (the two ends rope capacity is consistent) ratchet and be in safety position.Whether inspection hoist steel wire rope set bolt is tightened; The manual elevator that hoists is then crossed over that frame body is partly assembled, after anchoring accomplishes, just can safety net be installed; Its installation procedure is: first impelling nylon yarn is messenger just, draws endless rope successively, reaches suspension strop with first messenger again.With endless rope safety net is spread out under suspension strop at last.
