Description
Technical Field
[0001] The utility model relates to a holding pole, in particular to a self-propelled double-rocker holding pole used for assembling a power transmission iron tower. Background Art
[0002] The pole is a special lifting equipment used for the assembly of transmission towers in power transmission line projects. It is mainly divided into single-arm pole and double-arm pole. The double-arm pole consists of a tower body composed of a main pole and multiple standard sections and rockers symmetrically arranged on both sides of the main pole. The rockers can be rotated from horizontal to vertical at any angle through wire ropes. During the construction process, the tower body stands on the ground at the center of the transmission tower foundation. The height of the tower body can be increased as the tower assembly height increases through the lifting hydraulic cylinder and multiple fixed-length (height) standard sections, thereby effectively improving the work efficiency of the transmission tower assembly. At present, with the increasing number of power grid construction lines, the assembly environment of transmission towers has become more and more complex, such as mountainous areas, hills, plateaus, muddy land, etc. Due to the characteristics of heavy weight and many components of the poles currently used in tower assembly, transportation is more difficult. Especially when encountering complex tower assembly environments such as hills, narrow and curved roads, it is impossible to use medium and large transportation equipment. The poles can only be disassembled, carried manually, and then assembled. This process is not only labor-intensive, but also time-consuming and labor-intensive. On the other hand, in the process of raising the tower body of the existing boom, the standard sections are placed one by one in the outer frame (basic sleeve) manually. Since the standard sections must be connected and fixed to each other by bolts, it is difficult to make the connecting parts between the standard sections match each other by manually placing the standard sections. It is necessary to manually adjust the position many times, which brings many inconveniences to the tower body raising operation of the boom. Therefore, it is necessary to improve it. Summary of the invention

[0021] The lifting head 10 includes a fixed rod and a support rod. A piston connector 20 is arranged at the center position of the fixed rod. A piston connecting ear plate 21 is fixedly installed on the piston rod of the lifting hydraulic cylinder 9. The piston connecting ear plate 21 is hinged with the piston connector 20. Support rods are symmetrically arranged on the fixed rod. The cross section of the support rod is in the shape of a Chinese character "𠃎". In the process of lifting the standard section 11, the standard section 11 can be effectively prevented from slipping off the support rod. An assembly hole 19 is arranged on the support rod. A blind hole is arranged on the base base 3 corresponding to the assembly hole 19. When working, the assembly hole 19 is threadedly connected with the blind hole by bolts, so that the lifting head 10 is detachably fixedly connected to the base base 3. When working, the bolts can be pulled out from the lifting head 10 to release the fixed connection between the lifting head 10 and the base base 3, so that the standard section 11 can be lifted by the lifting head 10.
[0022] The basic sleeve 2 is a hollow frame body (space truss structure), and guide rollers (wheels) are arranged at the corners of the inner wall of the basic sleeve 2. The main rod 6 can be spliced with multiple standard sections 11 by bolts. The head and tail of each standard section 11 are spliced with each other and locked into one by bolts. An opening 16 for the main rod 6 to enter and exit is arranged on one side of the bottom end of the basic sleeve 2; a slide plate is hinged on the inner wall of the basic sleeve 2 corresponding to the opening 16, and the slide plate is composed of a fixed frame 12 and a plurality of rollers 13 installed in parallel on the fixed frame 12.

When working, the slide plate is pulled by the folding rod 15, and the slide plate is inclined relative to the basic sleeve 2, so that the standard section 11 can slide along the roller 13 on the slide plate to the opening of the basic sleeve 2. The roller 13 can reduce the contact area between the standard section 11 and the slide plate, thereby reducing the friction between the two.
[0023] The opening 16 is larger than the height of the standard section and the length of the slide plate, so that the standard section 11 can smoothly enter the basic sleeve frame 2 during operation, and at the same time, it is convenient for the slide plate to be stored in the opening of the basic sleeve frame 2 when the folding rod 15 is folded.

The main rod upper pulley block 23 is arranged on the top of the main rod 6, and the main rod lower pulley block 24 is arranged at the bottom of the main rod 6. The main rod 6 on both sides of the main rod lower pulley block 24 is symmetrically installed with rocker arms 25 through pin shafts.
