Abstract
The utility model discloses a span balance rod which is characterized by comprising a baffler, a connecting plate, two steel pipes and two rollers, wherein one end of one steel pipe is abutted with one end of the other steel pipe, the other ends of the two steel pipes are respectively sleeved with the roller, two ends of the roller are both provided with the bafflers, and the connecting plate is arranged on the baffler of the roller far away from the abutted end of the steel pipe.
Description
Technical field
The utility model relates to the leap balancing pole of striding thing under a kind of protection that is used for using when power transmission lines overhauling is changed overhead ground wire.
Background technology
When in power transmission lines overhauling, changing overhead ground wire, stride thing in order to protect down, the ground wire that can not make relaxes gets off with under stride thing and contact.The ground wire that traditional leap protection needs to change is enclosed within on the pulley sheave, and links with white palm rope and coaster and to connect, and by number people pulling and control white palm rope coaster is arrived and need protect crossover point.In the ground wire relaxation, when ground wire was lower than lead, artificial pull-up was passed the white palm rope of lead top coaster and ground wire is held, and avoided ground wire to continue to descend, thereby reached the purpose that protection is striden down.
Following problem appears in traditional leap protection easily:
1) because the aluminium hydraulic pressed connecting pipe that overhead ground wire exists, and new and old ground wire connector is excessive or irregularity etc., all can occur bigger jam phenomenon in the ground wire distraction procedure, influences construction schedule.
2) in distraction procedure, overhead ground wire easily causes disconnected strand of ground portion with each angular turn of coaster.By the leap coaster time, disconnected strand penetrates between pulley wall and the wallboard, makes it in a dilemma, and floor treatment is difficulty very, in case occur and will delay several hours, seriously upsets planned time.
3) every place is crossed over all needs number people (2-3 people) guard monitoring, keeps close, and the timely notice that encounters problems stops the ground wire traction, makes the construction interface many, wide, random, wayward.
4) white palm rope for a long time with lead and later direction shake back and forth, white palm rope is friction back and forth on lead, disconnected easily strand damaged, has bigger security risk hidden danger.
5) cross over the monitoring personnel and need pay close attention to field condition, need in time to adjust height according to the relaxation cases of overhead ground wire, difficulty is bigger, and muscle power is passed in time and descended, and the protection of object being spanned can not get ensureing fully.
The utility model content
Technical problem to be solved in the utility model be to provide a kind of can effectively protect down stride thing, safe and reliable, the leap balancing pole of phenomenons such as jam can not appear, and can be applicable to and discharge two overhead ground wire work simultaneously, further increase work efficiency.
The technical solution of the utility model is as follows: a kind of leap balancing pole, it is characterized in that: comprise baffle plate, connecting plate, two steel pipes and two roller bearings, the one end butt joint of two steel pipes, the other end all is set with a roller bearing, the two ends of described roller bearing are equipped with baffle plate, and described roller bearing is provided with connecting plate away from the baffle plate of steel pipe butt end.
Adopt technique scheme; the connecting plate of crossing over balancing pole is by white palm rope (or steel wire rope; diameter 10mm) is fixed between two limit leads; balancing pole is controlled at the protection crossover point; according to the length of crossing over a plurality of leap balancing poles that to be arranged in parallel; ground wire is under non-tension stringing situation; progressively be relaxed on the balancing pole; because balancing pole is fixed on the lead of lead both sides; overhead ground wire is unlikely to continue to descend again; thereby protected the safety of time striding, rolled and ground wire is acted on the roller bearing by tractive effort.
Its range of application mainly is to be used for changing 35kV circuit, 10kV circuit, the low pressure light current circuit that overhead ground wire relates to, and barriers such as house, economic forest are avoided the injury of ground wire to object being spanned.
What cross over balancing pole protection employing is point-to-point protection; simple and practical; can not block coaster because of dragging of overhead ground wire causes excessive aluminium hydraulic pressed connecting pipe, can be because of the disconnected of overhead ground wire strand is not stuck between wallboard and the pulley wall yet, only need a people can guard two and sentence up and down and stride.Cross over guard method with tradition and compare, improved operating efficiency greatly, alleviated staff's working strength, reduced security risk, for construction task safe, finish effective guarantee be provided smoothly.When need protections following striden the thing broad, can use two or more balancing poles to protect down according to factors such as landform, the discrepancy in elevation and stride.
In technique scheme, will cross over balancing pole for convenience and be fixed on the lead of limit by coaster, described connecting plate is the U font, is respectively equipped with a connecting hole on two side plate.
In technique scheme, connect for convenience and dismounting, the butt end of two steel pipes links together by ring flange.
In technique scheme, carry for convenience, be applicable to different both sides phase conductor width simultaneously, described leap balancing pole steel pipe is telescopic steel pipe.
Beneficial effect: the utility model is reasonable in design, simple in structure, enforcement is easy, convenient and practical.
Description of drawings
Fig. 1 is the structural representation of embodiment 1;
Fig. 2 is the structural representation of embodiment 2.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, the utility model is made up of baffle plate 3, connecting plate 4, two seamless steel pipes that length is identical 1, two roller bearings that length is identical 2 and ring flange 5, the one end butt joint of two steel pipes 1, and link together by ring flange 5, the other end all is set with a roller bearing 2, and the two ends of described roller bearing 2 are equipped with baffle plate 3, and described roller bearing 2 is provided with connecting plate 4 away from the baffle plate 3 of steel pipe 1 butt end, described connecting plate 4 is the U font, is respectively equipped with a connecting hole 4a on two side plate.
Other structures are identical with embodiment 1, and steel pipe 1 adopts telescopic steel pipe, are convenient for carrying, when changing two overhead ground wires, on the lead in the middle of the ring flange 5 usefulness white palm ropes of centre can being fixed on by coaster.
The utility model is not limited to embodiment, and described connecting plate 4 also can be other shapes.The length of two roller bearings 2 and two steel pipes also can be different, as long as can allow overhead ground wire relax on roller bearing 2 just.
