The derrick for assembling the electric transmission line iron tower, disclosed by the utility model, has the advantages that convenience and practicability are realized, the working efficiency can be increased, and the construction cost can be reduced.
Description
Technical field
The utility model designs a kind of transmission line of electricity installation component, the vertical pole of using of especially a kind of iron tower of power transmission line group.
Background technology
Pole is a kind of by the Lifting implements of tractor and wire rope lifting shaft tower etc., and in power line construction is built, it is vertical that pole is widely used in iron tower of power transmission line group at present.In prior art, the top assembly of pole generally only includes one group of single-sheaved block group or one group of sister block group, according to different towers, tower height, cross-arm, heavily adopt different handling methods, sometimes need the one-sided tower material of slinging, sometimes need again simultaneously the both sides tower material of slinging, need to change at any time like this top assembly of pole, time-consuming taking a lot of work, operating efficiency is low, increases unit construction cost.
Utility model content
Technical problem to be solved in the utility model is: the defect that overcomes above prior art, a kind of top assembly that do not need to change is provided, also can the various tower materials of handling, convenient and practical, can increase work efficiency, reduce the vertical pole of using of iron tower of power transmission line group of construction cost.
Technical solution adopted in the utility model is: provide a kind of iron tower of power transmission line group vertical with pole, comprise base assemblies, lower cone section frame body, straight section frame body, upper cone section frame body and top assembly, described base assemblies and lower cone section frame body are bolted, described straight section frame body and lower cone section frame body and upper cone section frame body are bolted, the two ends of described top assembly are provided with one group of single-sheaved block group, and the single-sheaved block group at described top assembly two ends is provided with one group of sister block group near the inner side at top assembly center.
Adopt after above structure, the utility model iron tower of power transmission line group is vertical compared with prior art to have the following advantages with pole: the single-sheaved block group at top assembly two ends is provided with one group of sister block group near the inner side at top assembly center, when the tower material that will lift by crane is lighter, can use the lifting of single-sheaved block group, when the tower material that lifts by crane is heavier, can use the lifting of sister block group, use single-sheaved block group can carry out one-sided lifting, sister block group is carried out bilateral lifting, changing the top assembly that does not need manually to change again pole when lifting requires, reduce the working time, increase work efficiency, unit in charge of construction does not need to buy two kinds of top assemblies simultaneously yet, can reduce construction cost.
As improvement, described top assembly and upper cone section frame body are hinged for what can horizontally rotate, can make top assembly circumferentially freely rotate, and facilitate transporter tower material to appropriate location.
As improvement, outside, described top assembly two ends is also hinged with and prevents that hoisting wirerope from deviating from the block of pulley groove, opens block and conveniently packs wire rope into, and when closed block prevents from using single-sheaved block group, wire rope deflects away from pulley groove.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, the utility model provides a kind of iron tower of power transmission line group vertical with pole, comprise base assemblies 1, lower cone section frame body 2, straight section frame body 3, upper cone section frame body 4 and top assembly 5, described base assemblies 1 is bolted with lower cone section frame body 2, described straight section frame body 3 is bolted with lower cone section frame body 2 and upper cone section frame body 4, the two ends of described top assembly 5 are provided with one group of single-sheaved block group 7, and the single-sheaved block group 7 at described top assembly 5 two ends is provided with one group of sister block group 8 near the inner side at top assembly 5 centers.Described top assembly 5 is hinged for what can horizontally rotate with upper cone section frame body 4.Described top assembly 5 outsides, two ends are also hinged with and prevent from lifting by crane the block 6 that steel wire is deviate from pulley groove.
The utility model as shown in Figure 4, is opened block 6 when using single-sheaved block group, lifting steel wire 9 is packed into the pulley groove of single-sheaved block group 7, closed block 6, and the one-sided assembly pulley by steel tower, pulls wire rope, the one-sided tower material 10 of slinging; While using sister block group, as shown in Figure 5, the space that lifting steel wire 9 is passed between single-sheaved block group 7 and sister block group 8, packs the pulley groove of sister block group 8 into, and the assembly pulley by steel tower both sides, pulls wire rope, the both sides tower material 10 of slinging; According to the difference that plays tower crane material 10 installation site of wanting, the top assembly 5 that can rotate in a circumferential direction, is installed to correct position tower material.
With regard to the utility model preferred embodiment, be described above, but can not be interpreted as it is limitations on claims.This practicality is carried out and is not only confined to above embodiment, and its concrete structure allows to change, and all various variations of doing in the protection domain of the utility model demand for independence are all in protection domain of the present utility model.
