The installation process of the installation template of the present invention when the wrist arm is installed is as follows.

First of all, it needs to be explained that there is a standard center distance between the flat arm and the inclined arm that needs to be installed. The center distance refers to the distance between the single ear positioning hole of the flat arm insulator and the single ear positioning hole of the inclined arm insulator. The range is generally in 1500mm ~ 1900mm, after the center distance is determined, the angle between the flat arm and the oblique arm is also a known parameter. On the basis of the known parameters, the installation process of the present invention when installing the wrist arm is:

(1) Adjust the center distance. By adjusting the translation component, the distance between the insulator lug connection holes of the two arm installation components is the standard spacing, and the rotation axis of the rotation component of the inclined arm is taken as the zero scale (the insulator ear connection of the inclined arm hole corresponds to this axis of rotation), the spacing can be obtained by reading the dimension pointer. Since the rear part of the arm tube is hinged together during installation, and the center distance and included angle parameters are known in advance, after the center distance is adjusted through the translation component, the angle is adjusted through the rotation component of the inclined arm arm. The angle can be read by the angle pointer. That is to say, the center distance and angle between the flat arm and the oblique arm are basically consistent with the standard distance and angle through the adjustment of the adjustment assembly.

(2) Assemble the upper and lower insulators. Put the insulator in the opened insulator holder 510 manually or by a mechanical arm, and connect and position the one-ear connection hole of the insulator with the positioning pin 704, and operate the hydraulic valve group 113 to supply power to the oil cylinder, so that the insulator holder 510 clamping insulators. Use this method to fix flat wrist insulators and oblique wrist insulators.

In this step, the positioning of the insulator can be achieved by adjusting the insulator positioning member 700 and the fine-tuning device 120 to align the one-ear connection hole of the insulator with the positioning pin 704 .

(3) Assemble the wrist tube. After the insulator is installed and fixed, put the arm tubes of the inclined arms and flat arms connected by the rear end rotation into the corresponding arm tube holders, and then insert the arm tubes into the corresponding insulator connection holes to operate the hydraulic pressure. The valve group 113 supplies power to the oil cylinder, so that the wrist-arm tube clamping part 550 clamps the wrist-arm tube.

In this step, if it is necessary to adjust the distance between the insulator clamping piece and the wrist-arm tube clamping piece, the movement adjustment is carried out by pushing the wrist-arm tube clamping piece to slide on the lateral translation assembly 600. After moving in place, set The position of the fixing device on the third sliding part 610 at the lower part of the insulator holder is fixed. The fixing device includes but is not limited to a bolt passing through the third sliding part 610. By turning the bolt, the bolt is aligned with the third sliding part 610 and Movement between the fourth sliding parts 620 is restricted.

At the same time, since the connection of the lower part of the clamping piece is a flexible connection, it can be fine-tuned in any direction with the help of the lever principle, which makes the positioning of the single-ear connection hole of the wrist-arm insulator and the installation of the wrist-arm support between the two wrist arms more flexible.

(4) Adjust the shape of the wrist arm. According to the drawing, adjust the shape of the arm, and finally fix the arm support between the two arms.

(5) Unscrew the positioning pin. Unscrew the positioning pin 704 to separate it from the single-ear connection hole of the flat arm arm insulator. Do the same operation to separate it from the single-ear connection hole of the oblique arm insulator.

(6) Fix the positioning plate. Tighten the positioning bolts 454 of the second positioning plate 451 of the inclined arm and the flat arm to prevent the relative position of the arm and the formwork platform from shifting during the lifting process.

The above process completes the installation of the wrist arm on the installation template. As shown in Figure 8.

In the description of this specification, specific features, structures, materials or characteristics may be combined in any one or more embodiments or examples in an appropriate manner.

The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily imagined by those skilled in the art within the scope of the disclosure of the present invention should be covered within the protection scope of the present invention.
