Abstract
The utility model relates to a high tower assembled derrick hoisting hoop. An existing high tower assembled derrick is not provided with a protection device. The utility model discloses a long-span high tower assembled derrick hoisting hoop, which is characterized in that hoisting hoops are respectively arranged on four main pipes of a derrick, and comprises vertical arc-shaped plates, wherein transverse connecting plates are arranged on the upper portion of the vertical arc-shaped plates, the vertical arc-shaped plates are matched with the outer circumference walls of the main pipes, and a space which can store hoisting steel wire sleeves is formed between the vertical arc-shaped plates and the transverse connecting plates. The long-span high tower assembled derrick hoisting hoop is specially used for hoisting protection of derricks, is simple and reasonable in structure and convenient to mount, and has excellent protection degree.
Description
Technical field
The utility model belongs to the vertical auxiliary equipment of a kind of electric transmission line high tower group, and especially a kind of high tower group erection of derrick promotes anchor ear.
Background technology
Along with the development of electrical network construction, particularly cross over increasing of bay, great river, great river, navigation channel etc., cross over greatly high tower and also increase in transmission line of electricity application thereupon; High tower derrick, as high tower ancillary facility, needs in construction, as stepping on tower facility and pole body, need be connected with tower body by adhering to frame beam.In high tower group is vertical, need repeatedly promote high tower derrick, because high tower derrick supervisor lifting place does not arrange protection facility, derrick is easily damaged after promoting, and causes damage.
Utility model content
The technical assignment of the technical problems to be solved in the utility model and proposition is that prior art scheme is improved and improved; provide a kind of large leap high tower group erection of derrick to promote anchor ear; to reach, derrick is effectively protected in lifting process, and there is the object of good applicability.For this reason, the utility model is taked following technical scheme.
A kind of large leap high tower group erection of derrick promotes anchor ear, it is characterized in that: promote anchor ear and be separately positioned on four supervisors of derrick, promote anchor ear and comprise perpendicular arc, the top of described perpendicular arc arranges horizontal junction plate, described perpendicular arc matches with supervisor's outer circle wall, forms and hold the space that promotes steel wire cover between described perpendicular arc and horizontal junction plate.The utility model has designed a set of protection anchor ear that derrick promotes that is exclusively used in, simple and reasonable, easy for installation, has preferably protection, and the technical program is not only protected derrick, and protection steel wire cover, and arc anchor ear is avoided the damage of steel wire cover, fractureed.
As the further of technique scheme improved and supplemented, the utility model also comprises following additional technical feature.
The middle part of described perpendicular arc arranges arc boss, forms the described space that promotes steel wire cover that holds between described arc boss and perpendicular arc.By arc boss is set, the residing space of steel wire cover is optimized to strengthening, effectively strengthen the safety of lift headframe process.
On described horizontal junction plate, have shackle hanging hole.This hanging hole is for coupling hook, to be connected with the anchor ear of contraposition by steel cable.
The top of described horizontal junction plate arranges connecting screw rod, by this screw rod, is connected with the stiffener of derrick.
Between two lifting anchor ears on diagonal angle, by steel strand, connect.Each anchor ear is connected and composed to overall structure by steel cable, effectively strengthened the bulk strength of hooping structure, promote safety.
Described perpendicular arc and horizontal junction plate one are welded.
The beneficial effects of the utility model have been to design one and for plaing, have protected and the anchor ear of stability maintenance effect when being exclusively used in derrick and promoting; simple and reasonable; easy for installation; strengthened derrick geometry; safety is protected, and not only protects derrick, and protection steel wire cover; arc anchor ear, avoids the damage of steel wire cover, fractures.

The specific embodiment
Below in conjunction with Figure of description, the technical solution of the utility model is described in further detail.
A kind of large leap high tower group erection of derrick as illustrated in fig. 1 and 2 promotes anchor ear, derrick comprises four supervisors 1, lifting anchor ear 5 is connected on four supervisors 1 of derrick, promote anchor ear 5 and comprise perpendicular arc 2, the top of perpendicular arc 2 arranges horizontal junction plate 3, perpendicular arc 2 is welded with horizontal junction plate 3 one, and perpendicular arc 2 matches with supervisor's 1 outer circle wall.On horizontal junction plate 3, have shackle hanging hole 4.The top of horizontal junction plate 3 arranges connecting screw rod 7 for connecting the stiffener of derrick.
The middle part of perpendicular arc 2 arranges arc boss 6 as shown in Figures 3 and 4, forms and hold the space that promotes steel wire cover between arc boss 6 and perpendicular arc 2.
As shown in Figure 5, two on diagonal angle promote between anchor ear 5 and connect by steel strand 9.
Along with construction extensive, high-grade electricity power engineering, large use of crossing over high tower derrick lifting anchor ear also will be more and more frequent, particularly cross over increasing of the stringing engineerings such as bay, great river, great river, navigation channel, be high tower derrick lifting anchor ear applying in power transmission line vertical tower engineering wide space is provided.
It is specific embodiment of the utility model that a kind of large leap high tower group erection of derrick shown in above picture in picture 1-Fig. 5 promotes anchor ear; the utility model substantive distinguishing features and progress have been embodied; can be according to actual use needs; under enlightenment of the present utility model; it is carried out to the equivalent modifications of the aspects such as shape, structure, all at the row of the protection domain of this programme.
