[0001] The invention relates to the technical field of spiral anchor construction, and in particular to a transmission line iron tower spiral anchor foundation installation device and a construction method. Background Art

[0002] Transmission line towers are structures used to support transmission lines, usually made of metal materials, used to support the conductors and insulators of the transmission lines. Screw anchors are a type of foundation engineering equipment used to fix or support buildings, structures or other facilities. It usually consists of one or more spiral-shaped screws that are screwed into the ground to fix the structure to the foundation, including soil, sand, etc. They are often used in foundation engineering projects that require fast, economical, and vibration-free or noise-free installations, such as solar power plants, sheds, bridges, protective walls, etc.

[0003] Referring to the Chinese patent document with authorization announcement number CN216275679U, a mobile and flexible spiral anchor construction device is disclosed, including an excavator working platform, the free end of the operating arm of the excavator working platform is rotatably connected to a bracket, the other side of the bracket is hinged with a power assembly, and the other end of the power assembly is equipped with a spiral anchor, and the hydraulic motor at the upper end of the drill rod is connected to the bracket through an articulated shaft, and the operating arm of the excavator working platform has difficulty in controlling the angle of entry of the spiral anchor into the ground.

[0004] With regard to the above-mentioned related technologies, for the spiral anchor, there are construction requirements for the angle at which the spiral anchor enters the ground. The spiral anchor usually needs to be drilled into the ground at a certain angle for easy fixation. After the spiral anchor is inserted into the ground, it is easy to cause the spiral anchor to be pushed off track, which is difficult for the staff to control. The existing technology requires auxiliary equipment to control the angle at which the spiral anchor enters the ground. However, due to the construction site environment, it is difficult for the staff to operate and has certain risks. Summary of the invention

[0005] In view of this, the present invention provides a transmission line tower spiral anchor foundation installation device and a construction method, aiming to solve the problem that the spiral anchor cannot be adjusted when inserted into the ground.

[0006] To solve the above technical problems, in the first aspect, the present invention provides a transmission line tower spiral anchor foundation installation device, comprising an excavator body and a spiral anchor, and also comprising: a moving mechanism, which is arranged on the excavator body and is used to drive the spiral anchor to move, the bottom of the moving mechanism is connected to a support platform, the bottom of the support platform is hinged with a power member, the spiral anchor is installed at the other end of the power member, a first linear drive is hinged at the bottom of one side of the power member, a counterweight column is hinged at the top of one side of the power member, and the drive shaft of the first linear drive is hinged to the counterweight column.

[0007] By adopting the above technical solution, when the angle of the spiral anchor needs to be adjusted, the angle between the spiral anchor and the counterweight column is changed by rotating the counterweight column, thereby adjusting the position of the center of gravity of the spiral anchor and the counterweight column so that the spiral anchor can be maintained at a specified angle position, and then the spiral anchor is inserted into the ground through the moving mechanism to facilitate the installation of the spiral anchor.

[0008] Optionally, a second linear actuator is fixedly mounted on one end of the counterweight column away from the power member, and a driving shaft of the second linear actuator is fixedly connected to a connecting column.

[0012] Optionally, the moving mechanism includes an electric hoist installed on the excavator body manipulator arm, the bottom of the electric hoist is connected to a moving platform, and the support platform is fixedly connected to the bottom of the moving platform.

[0014] Optionally, a flywheel is rotatably arranged inside the support platform.

[0015] By adopting the above technical solution, the rotation of the flywheel can provide additional momentum and angular momentum, help maintain the stability of the system, reduce the probability of deviation during installation of the spiral anchor, and facilitate the installation of the spiral anchor.

[0016] In a second aspect, the present invention provides a method for constructing a spiral anchor foundation of a power transmission line tower, which is applied to a transmission line tower spiral anchor foundation installation device in the first aspect, and the method is:

[0022] Optionally, in method S2, the second linear drive is started to drive the connecting column to move to a maximum position.

[0023] By adopting the above technical solution, when the connecting column moves to the maximum position, the center of the counterweight column and the connecting column can be changed, which is beneficial to improving the stability of the system.

[0024] Optionally, in method S4, the electric hoist drives the support platform to move in a direction away from the excavator body, and drives the support platform to move downward at the same time.

[0025] By adopting the above technical solution, the movement of the electric hoist can improve the stability of the spiral anchor during installation.

[0026] In summary, compared with the prior art, the present invention includes at least one of the following beneficial technical effects:

[0027] 1. When the angle of the spiral anchor needs to be adjusted, the angle between the spiral anchor and the counterweight column is changed by rotating the counterweight column, thereby adjusting the position of the center of gravity of the spiral anchor and the counterweight column so that the spiral anchor can be kept at the specified angle position, and then the spiral anchor is inserted into the ground through the moving mechanism to facilitate the installation of the spiral anchor;

[0028] 2. After adjusting the position of the connecting column, the center of gravity of the counterweight column can be changed, thereby changing the center of gravity of the spiral anchor and the counterweight column, and adjusting the angle of the spiral anchor. The movement of the connecting column and the rotation of the counterweight column can speed up the adjustment of the spiral anchor, which is conducive to improving work efficiency. When the connecting column is moved to the maximum position, the length of the counterweight column and the connecting column reaches the longest state, which is conducive to improving the stability of the spiral anchor when it is inserted into the ground.
