Description
Technical field
The utility model belongs to electric power transmission line erection technique field, specifically relates to a kind of steel pipe pole structure that is used to tighten up lead.
Background technology
In the prior art, set up electric power transmission line and often will use steel pipe pole, steel pipe pole structure commonly used as shown in Figure 1, steel pipe pole 1 upper end is provided with cross-arm 2, fixed installation prestretch block 3 in cross-arm 2 ends penetrates stringing steel wire rope 5 in this prestretch block 3, stringing steel wire rope 5 one ends connect lead 4; Bury one underground apart from the position of steel pipe pole 1 certain distance (this distance generally must not less than the height of steel pipe pole 1) on the ground and turn to earth anchor 7, turn to earth anchor 7 oblique upper to power be converted into the power of horizontal direction; Fix a ground corner block 6 on the earth anchor 7 turning to, after stringing steel wire rope 5 other ends pass ground corner block 6, be connected on the wire stretcher mill 8, realize the stringings operation by wire stretcher mill 8.
Though above-mentioned structure can meet the demands, have following shortcoming:
(1) after a phase conductor stringing end-of-job, must put down steel pipe pole to the stringing steel wire rope earlier, after connecting another phase conductor, hang on steel pipe pole again and carry out the stringing work of next phase conductor, because the stringing steel wire rope is heavier, cause staff's work load bigger, and will spend certain operating time.
(2) ground must be buried one underground and turn to earth anchor.Turn near the soil property of earth anchor requirement steel pipe pole solid owing to bury underground, need enough open geographical position simultaneously, requiring wastes time and energy than tight and operation, has increased work load and workload.
(3) the above transmission line line tightening method of ultra-high-tension power transmission line such as 35kV need adopt secondary stringing method usually.Long crimping process of a time after printing and finish, stringing of lead is arranged, if it is only prepare a cover stringing equipment, then more time-consuming; If prepare two cover stringing equipment, increased workload then for again instrument loading and unloading in transportation, the work and work clearing out a gathering place after finishing, strengthened work load.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of simple and ingenious structure is provided, and erection construction is convenient, the low and steel pipe pole structure that is used to tighten up lead that economizes labor time of work load.
The technical scheme that provides according to the utility model, the described steel pipe pole structure that is used to tighten up lead comprises steel pipe pole, cross-arm, prestretch block, stringing steel wire rope and wire stretcher mill, it is characterized in that: the steel pipe pole upper end is fixed with many cross-arms, every cross-arm end (lead hanging point place) fixed installation prestretch block, the steel pipe pole top is installed with first corner block, the lower end is installed with second corner block, the stringing steel wire rope is walked around the prestretch block bottom successively, the first corner block top, the second corner block bottom, the one end is connected with lead, and the other end is connected with the wire stretcher mill.
The utility model simple and ingenious structure, erection construction is convenient, and compared with prior art, advantage is: the stringing steel wire rope can easily shift in the prestretch block of two cross-arm ends, saves manpower, time and workload; Second corner block is fixed in the steel pipe pole lower end, has saved to bury underground to turn to the ground anchor operation link, reduces work load, saves the activity duration; Requirement to the steel pipe pole geographical position reduces, and the scope of application is more extensive; The ground crimping work of last phase conductor is finished and printing of next phase conductor carried out synchronously, and the entire job process has been accelerated in cross-operation greatly.
Description of drawings
Fig. 1 is a steel pipe pole structural representation of the prior art.
Fig. 2 is a structural representation of the present utility model.
Description of reference numerals: 1-steel pipe pole, 2-cross-arm, 3-prestretch block, 4-lead, 5-stringing steel wire rope, 6-ground corner block, 7-turn to earth anchor, 8-wire stretcher mill, 9-the first corner block, 10-the second corner block.
Embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in Figure 2, the utility model is mainly by steel pipe pole 1, cross-arm 2, prestretch block 3, stringing steel wire rope 5, wire stretcher mill 8, first corner block 9 and second corner block 10 are formed, steel pipe pole 1 erects on the ground, steel pipe pole 1 upper end is fixed with two cross-arms 2, every cross-arm 2 ends fixed installation prestretch block 3, steel pipe pole 1 top fixedly mounts first corner block 9, the lower end fixedly mounts second corner block 10, stringing steel wire rope 5 is walked around prestretch block 3 bottoms successively, first corner block, 9 tops, second corner block, 10 bottoms, the one end is connected with lead 4, and the other end is connected with wire stretcher mill 8.Wherein, second corner block 10 be used for oblique upper to power be converted into the power of horizontal direction; Wire stretcher mill 8 is used to provide the power of stringing.
When the utility model is used for tight heterogeneous lead 4, because the total weight of stringing steel wire rope 5 is carried by first corner block 9 at steel pipe pole 1 top, after the stringing work of a phase conductor 4 is finished, the staff can be stringing steel wire rope 5 in the prestretch block 3 of easily transferring to another cross-arm 2 ends on the bar, be connected with another phase conductor 4, save time, reduce workload.
Because every phase conductor 4 all needed to tighten up twice when setting up: tightening up for the first time is that lead 4 is printed, loose ends crimping then; After crimping is finished, tighten up for the second time again, this phase conductor 4 is fixed.After adopting the utility model, finish in the work of printing, when the Ground Operation personnel carried out crimping to this phase conductor 4, the operating personnel can launch the work that prints to next phase conductor 4 simultaneously on the bar.The ground crimping work of last phase conductor 4 is finished and printing of next phase conductor 4 carried out synchronously, and cross-operation can be accelerated the entire job process greatly.
