Description

Technical Field

[0001] This utility model relates to the field of power towers, and in particular to an installation structure for a power tower base. Background Technology

[0002] Power towers are important infrastructure used to support and erect power lines. They are widely used in power transmission and distribution systems. Power towers include concrete poles, steel poles, etc. They are relatively short and are distributed in urban streets, rural areas, and other areas. They are responsible for converting high-voltage electricity into low-voltage electricity suitable for home and business use, realizing the "last mile" transmission of electricity.

[0003] However, in the current installation of power towers, the foundation construction mostly adopts the method of cast-in-place concrete, which requires excavation of the foundation pit, then binding of steel bars, setting up of formwork, and finally pouring concrete to form the base. The construction speed of connecting the power tower to the base in this way is slow, which reduces the installation efficiency of the power tower. In addition, the base structure is difficult to recycle and reuse later.

[0004] To address these issues, we propose an installation structure for the base of a power tower. Utility Model Content

[0005] The purpose of this utility model is to provide an installation structure for a power tower base to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An installation structure for a power tower base includes a concrete counterweight base, a concrete connecting seat on top of the concrete counterweight base, a fixing seat fixedly connected to the upper surface of the concrete connecting seat, a concrete tower inside the fixing seat, two positioning holes on the upper surface of the concrete connecting seat, two positioning protrusions on the upper surface of the concrete counterweight base, the tops of the two positioning protrusions penetrating the positioning holes and extending above the positioning holes, a first through hole on the outer surface of the two positioning protrusions, two second through holes on the outer surface of the fixing seat, two threaded sleeves fixedly embedded on the outer surface of the concrete tower, threaded fixing nails inside the two first through holes, and the outer surface of the threaded fixing nails matching the inner ring of the threaded sleeves.

[0008] In a further embodiment, a rectangular limiting plate is fixedly connected to the inner ring of the concrete tower, and a guide limiting block is fixedly connected to the upper surface of the concrete connecting seat. The outer surface of the guide limiting block is in contact with the inner wall of the rectangular limiting plate.

[0009] In a further embodiment, the outer surface of the fixing base is provided with a plurality of third through holes, and each third through hole is provided with a locking screw. The outer surface of the concrete tower is fixedly inlaid with a metal sleeve, and the outer surface of the metal sleeve is provided with a plurality of threaded grooves, and the inner wall of the threaded grooves is threadedly connected to the outer surface of the locking screw.

[0010] In a further embodiment, the upper surface of the concrete connecting seat is provided with two sets of circular holes, and the upper surface of the concrete counterweight base is fixedly connected with two sets of fixing screws. The top ends of the two sets of fixing screws pass through the circular holes and extend to the top of the circular holes. The upper surface of the concrete connecting seat is provided with two sets of locking nuts, and the inner ring of the locking nuts is adapted to the outer surface of the fixing screws.

[0011] In a further embodiment, two sets of lifting components are fixedly embedded on the outer surface of the concrete counterweight base, and the upper surface of the concrete counterweight base is in close contact with the bottom surface of the concrete connecting seat.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This structure utilizes prefabricated components. Pre-fabrication of the concrete counterweight base, concrete connecting seats, and concrete tower reduces on-site construction time. Positioning holes and protrusions facilitate rapid positioning and installation of the concrete counterweight base and connecting seats. Rectangular limiting plates and guide blocks allow for connection between the concrete connecting seats and the concrete tower. Threaded fixing screws and other locking mechanisms enable quick and easy connection and fixation of the concrete counterweight base, connecting seats, and tower, increasing installation speed. Furthermore, the components are detachable via threaded fixing screws and locking bolts, allowing for easy separation and recycling during later dismantling. Attached Figure Description
