Abstract
The utility model discloses a bridge type protective device used for replacing overhead lines. The bridge type protective device comprises a bearing rod. Each of two ends of the bearing rod is equipped with a bearing. A sleeve ring is arranged outside each bearing, a pull bar is adopted to be movably connected with each sleeve ring, and the tail end of each pull bar is provided with a top ring. The bridge type protective device has the advantages of being ingenious in design, simple in structure, easy to produce and manufacture, simple to operate, etc. By using the bridge type protective device to replace overhead lines, workers only need to drag ropes on the ground, so the device fast in speed and high in efficiency helps to ensure safety of the operating workers. The bridge type protective device allows force bearing of overhead lines to be effectively reduced to make the overhead lines isolate from span equipment, such that objects to be spanned and the overhead lines are all protected. Moreover, the bridge type protective device can be utilized repeatedly to lower the use cost to the maximum.
Description
Technical field
The utility model relates to the device using when power domain adopts tension stringing mode to change overhead wire, is specifically related to a kind of for changing the bridge-type protective device of overhead wire.
Background technology
At power domain, more because of old circuit, the work of changing overhead wire is very frequent.Tension stringing is to make the wire being unfolded keep certain tension force and depart from the erection construction method of ground in built on stilts state, and at present, electric power enterprise is mostly carrying out the overhead wires such as restringing, ground wire by the method for tension stringing.
At tension stringing, change in overhead wire process, scissors crossing owner will comprise power line, order wire, house, highway etc., house is generally not too high, during replacing, only need send special messenger to guard, highway also can be by the Sign Board of " power construction, Slow Down " being set and sending special messenger to guard to realize, when scissors crossing thing is power line, change overhead wire just cumbersome, because it is much higher that power line is crossed over thing than other, at present, the common method of protection power line has: set up crossing frame 1.; 2. power line let-down ground; 3. transform leap section as underground cable.The common issue that these three kinds of methods exist is that workload is large, and required financial resources, manpower are larger.
Utility model content
Technical problem to be solved in the utility model is, overcomes the above defect, provides one can protect leap thing, can protect again changed wire not impaired, and simple to operation for changing the bridge-type protective device of overhead wire.
In order to solve the above technical problem, the utility model is a kind of comprises bearing rod for changing the bridge-type protective device of overhead wire, and the two ends of described bearing rod are provided with bearing, and bearing outside is provided with the collar; Pull bar is set and is flexibly connected with the collar, the end of described pull bar is provided with apical ring.
As improvement, the two ends of bearing rod described in the utility model and bearing junction are provided with retaining ring.
Further, the outside of bearing rod described in the utility model is provided with protective sleeve; On the described collar, the another side relative with described pull bar link be provided with base ring.
Bridge-type protective device described in the utility model, reeve the apical ring of pull bar end, by wire or ground wire as load thing, pull-up bridge-type protective device, need the overhead wire of changing to ride on bearing rod, overhead wire and line balance converter isolation in Renewal process, namely adopt bridge-type protective device to make overhead wire and leap thing keep certain safe distance, and bear and when sag reduces, act on the power of crossing on thing, make like this to need stressed the reducing of overhead wire of replacing, construction safety coefficient increases, and to crossing over thing and overhead wire, do not cause damage again, safety completes tension stringing.
The beneficial effects of the utility model: owing to having used the above structure, the utlity model has design ingenious, simple in structure, easily manufacture, the advantage such as easy and simple to handle; With described bridge-type protective device, change overhead wire, personnel drag rope on ground, and speed is fast, efficiency is high, and guarantee operating personnel's safety; It is stressed that bridge-type protective device effectively reduces overhead wire, makes overhead wire and line balance converter isolation, both protected leap thing, again fender bracket ceases to be busy; Described bridge-type protective device can reuse, and reduces to greatest extent use cost.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The utility model is a kind of comprises bearing rod 8 for changing the bridge-type protective device of overhead wire, and the two ends of described bearing rod 8 are provided with bearing 1, and bearing 1 outside is provided with the collar 7; Pull bar 5 is set and is flexibly connected with the collar 7, the end of described pull bar 5 is provided with apical ring 4.
As improvement, the two ends of bearing rod 8 described in the utility model and bearing 1 junction are provided with retaining ring 2.
Further, the outside of bearing rod 8 described in the utility model is provided with protective sleeve 3; On the described collar 7, the another side relative with described pull bar 5 links be provided with base ring 9.
Embodiment: the core texture bearing 1 of bridge-type protective device described in the utility model and bearing rod 8 are selected respectively steel material and organic toughened glass material, not fragile, for the overhead wire that makes to be replaced does not damage bearing rod in sliding process, at the protective sleeve 3 of the additional one deck nylon material of bearing rod 8, can effectively protect bearing rod 8, through long-term, use, during protective sleeve serious wear, only need to change protective sleeve; On the collar 7, be welded to connect button 6, the collar 7 is stuck on bearing 1, at junction button 6 places, with screw, stayed mast 5 is flexibly connected with the collar 7, for fear of the overhead wire being replaced occasional in distraction procedure, surmount retaining ring 2 and skip to the position of junction button 6, lead wire and earth wire is caused to slight damage, the collar 7 can be done largerly, increase the radian of retaining ring 2, overhead wire is steadily present within the scope of protective sleeve in distraction procedure like this, unlikely damage lead wire and earth wire; On the described collar 7, the another side relative with described pull bar 5 links welding base ring 9, while needing, rope, through base ring 9, can be realized to bridge-type protective device and is moved horizontally, be both convenient for changing limit phase conductor, can play again stabilization.
