Abstract

The utility model discloses an assembled foundation base, which comprises a square base and a base frame. The middle of the base is provided with a fixing hole matched with the body of the electric pole holding tower, and the base is composed of several square base blocks of the same size. The foundation chassis is connected and fixed to each foundation bottom block. This scheme adopts the assembled base block, which is small in size and light in weight, and is suitable for disassembling the base and transporting it to the installation site. Because it is assembled, it is convenient to replace a damaged single foundation bottom block.

Description

Assembled foundation base

technical field

The utility model relates to an electric holding pole, in particular to a foundation base of a portable ground-mounted electric holding pole.

Background technique

With the development of the transmission line business, high-voltage direct and alternating current transmission towers have been erected in various regions, and some transmission towers have been erected in forests and mountainous areas. The ground conditions of such places are harsh, and conventional equipment such as: automobiles cannot be used. Common means of transportation such as cranes and trucks, the use of ordinary electric poles in such places has been greatly restricted. Appeared to be suitable for transportation thus, and the electric pole that is installed in mountainous area has appeared. But there are following problems in prior art:

The basic bases of electric poles are almost all of uniform specifications, with high single weight and large volume, and the installation sequence is unique, and there are no multiple installation methods. Installation tools such as steam cranes must be used for installation, and a large site needs to be leveled out, which are not conducive to installation in mountainous areas.

Contents of the invention

The utility model provides a detachable and assembled foundation base suitable for transportation and small in size.

The technical scheme adopted by the utility model to solve the above-mentioned technical problems is: an assembled foundation base, which is characterized in that it includes a square base and a base frame, and a fixing hole is provided in the middle of the base to cooperate with the electric pole holding tower body, and the base is composed of several The square basic bottom blocks of the same size are assembled, and the basic bottom frame is connected and fixed to each basic bottom block.

The periphery of the fixing hole of the base is provided with a fixed shaft wall surrounded by an I-shaped steel plate.

The outer four sides of the square base block are provided with a male buckle and a female buckle which are fixedly engaged with each other.

There are four square basic bottom blocks, and the basic bottom frame is a cross steel plate, and the cross steel plate fixes two basic bottom blocks on the diagonal.

There are 16 square base blocks, which are composed of 4 intermediate base blocks and 12 outer ring base blocks. The base base frame is a cross steel plate and an outer ring steel plate. The four foundation blocks of the line are fixed, and the outer ring steel plate fixes the outer ring foundation blocks.

Bolt holes are reserved on the base bottom block, and the cross steel plate and the outer ring steel plate are fastened to the base bottom block by bolts.

The utility model can choose the installation method of 4 or 16 foundation bases and foundation chassis according to the limitation of the site or conditions (on the basis of satisfying ground endurance conditions).

The advantages of this technical solution are:

The assembled base block is adopted, which is small in size and light in weight, and is suitable for disassembling the base and transporting it to the installation site. Because it is assembled, it is convenient to replace a damaged single foundation bottom block.

The connection between the foundation bottom blocks is ensured by the male buckle and the female buckle, and the foundation chassis composed of cross steel plates and outer ring steel plates is connected to ensure that the foundation base transmits the bending moment to each foundation bottom block and ensures the pressure bearing capacity of the base.

Detailed ways

The utility model will be described in detail below in conjunction with the accompanying drawings:

Embodiment 1: See Figures 1 and 2. The assembled foundation base includes a square base and a base frame. A fixing hole 2 is provided in the middle of the base to cooperate with the power holding pole tower body. The periphery of the fixing hole is provided with an I-shaped steel plate enclosure. Formed fixed well wall 3, the fixed well wall can fix the tower body on the foundation base. The base is composed of 16 square base blocks 1, specifically, 4 intermediate base blocks and 12 outer ring base blocks. The side of the base block is provided with a male buckle and a female buckle 4 that are fixedly engaged with each other. The basic chassis includes a cross steel plate 5 and an outer ring steel plate 7, and the cross steel plate connects two groups of four basic bottom blocks (respectively numbered 10, 2, 4, 16 marked in the diagram) , and 7, 1, 3, 13 groups) are fixed, bolt holes are reserved on the base block, the cross steel plate is fastened to the base block by bolt 6, and the outer ring steel plate plays the role of ring beam fixing, the The steel plate of the outer ring is fixed to the basic bottom blocks at the four corners of the base by bolts.

Embodiment 2: Referring to Figures 3 and 4, compared with Embodiment 1, the difference is that there are four base blocks, and the others are the same. This embodiment is convenient to set up the base of the electric holding pole on the narrow bottom surface, which is convenient for assumption and saves time.
