Description

Lightweight double flat arm seat to hold the pole

technical field

The utility model relates to a power pole holding device used for tower assembly in a power transmission iron tower, in particular to a portable ground-mounted power pole holding device.

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 power poles for lifting and hoisting have appeared. The existing power poles are high in weight, large in size, and have a unique installation sequence. Multiple installation methods do not exist. It is also inconvenient to carry, construct and install in mountainous areas. Due to the variable installation locations of transmission towers, for example, they need to be erected in mountainous areas, jungles and other places. The ground conditions in such places are harsh, the ground is uneven, the traffic is extremely inconvenient, and it is difficult to transport and erect tower equipment. Conventional equipment such as automobile cranes and trucks cannot be used. and other common means of transport. Therefore, there is a need for a small and portable double-arm electric holding pole.

Contents of the invention

The utility model provides a ground-mounted pole that is convenient for disassembly and assembly of the foundation base and the lifting arm, and is convenient for transportation.

The technical scheme adopted by the utility model to solve the above-mentioned technical problems is: a portable double-flat arm seat ground holding pole, including a tower body, a lead-out beam on the upper part of the tower body, and two hoisting arms with hoisting wire ropes hinged on the tower body. The lower part of the body is installed on the foundation base, and the top of the tower body, the end of the boom, and the lead-out beam are provided with a pulley block connected with the hoisting wire rope. Each is equipped with a pulley block connected with a steel wire rope. A steel wire rope for retracting the arm is passed through the pulley block at the end of the boom and the pulley block at the top of the tower body, and is fixed on a set of lead-out beam pulley blocks through the tower body, and another set of lead-out beam pulley blocks The lifting wire rope is threaded and wound; the foundation base is assembled by several identical square foundation bottom blocks, and the foundation bottom blocks are connected and fixed by the foundation bottom frame.

The side of the square base bottom block is symmetrically provided with a male buckle and a female buckle for fixed engagement.

There are four square foundation bottom blocks, and fixing holes for matching with the tower body are formed between the four foundation bottom blocks. The foundation bottom frame is a cross steel plate, and the cross steel plate fixes the two foundations bottom block.

There are sixteen square base blocks, which are composed of 4 middle base blocks and 12 outer ring base blocks. Fixing holes that match the tower body are formed between the four middle base blocks. The bottom frame includes cross steel plates and peripheral steel plates, the cross steel plates fix the four diagonal base blocks, the peripheral steel plates are frame structures, and fix the twelve peripheral base blocks.

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

The base base of the utility model is composed of base base blocks, which makes the base base be disassembled into several parts with light weight and small volume. The mass of each piece is not more than 250 kg, which is convenient for transportation. On the basis of ground endurance conditions), choose the installation method of 4 or 16 pieces. The 12 basic bottom blocks of the outer ring are installed in the form of male buckle and female buckle to ensure interchangeability. The permanent arm retracting wire rope on the boom not only greatly saves the time for arm retraction and dismantling the tower, but also reduces the time for high-altitude operations. In addition, the two-section lead-out beam structure is adopted, so that the arm-retracting wire rope is laid on the boom for a long time. When in use, it is only necessary to connect the rope end reserved on the lead-out beam with the wire rope in the lifting power mechanism, which is convenient and safe. .

Detailed ways

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

As shown in Figures 1, 2, and 3, the portable double-flat arm support pole includes a tower body 1 and is hinged with two symmetrical lifting arms 3. The upper part of the tower body has a lead-out beam 2, and the lower part of the tower body is installed on the foundation. on the base. The lead-out beam 2 has two groups of upper and lower groups. The two groups are respectively provided with four pulley blocks. The hoisting wire rope is threaded in turn to connect the trolley, the roller skating group 4, the roller skating group 5, a group of roller skating groups at the lower end of the outgoing beam, and the ground lifting mechanism; in addition, there is an arm retracting wire rope 6 that is threaded around the pulley group at the end of the boom, the tower The pulley block on the top of the tower body is passed through the tower body and fixed on a group of lead-out beams and roller blocks at the upper end of the lead-out beam.

The foundation base is composed of 4 middle base blocks 12 and twelve outer ring base blocks, a total of 16 identical square base blocks 12 are assembled, and the middle four base blocks form a fixing hole 7 that matches the tower body , The mutual contact surfaces of the base bottom blocks are provided with a male buckle and a female buckle 8 for fixed engagement. The foundation bottom block is also connected and fixed by the foundation chassis. The base chassis includes cross steel plates 9 and peripheral steel plates 11, the four base blocks on the diagonal are fixed by the cross steel plates, the peripheral steel plates have a frame structure, and the twelve base blocks on the periphery are fixed.

Bolt holes 10 are reserved on the foundation bottom block, and the cross steel plates and peripheral steel plates are fastened on the foundation bottom block by bolts.
