Description

Technical Field

[0001] The utility model relates to the technical field of anchor rod installation, and more specifically, to a tunnel anchor rod installation device. Background Art

[0002] Tunnel anchors are engineering components used to reinforce surrounding rock in tunnel construction. One end is connected to the engineering structure, while the other end is driven deep into the ground to enhance the stability and bearing capacity of the rock and soil. Installing anchors in tunnels requires the use of a movable work platform, but these platforms are often unstable, making them prone to slipping during installation and creating unnecessary difficulties.

[0003] After searching, the Chinese patent with announcement number CN217714416U discloses a working platform for anchor bolt installation in tunnels. By starting the servo motor to rotate forward, the winding wheel also rotates forward, tightening the wire rope. Under the pull of the wire rope, the two transmission plates and the sliding rod move relative to each other, causing the lifting plate to move downward. At the same time, the spring is stretched, and the support legs move downward until they are in contact with the ground. The moving wheels are separated from the ground. The support legs can provide stable support for the entire platform to prevent the platform from sliding, thereby achieving the purpose of good stability of the working platform.

[0004] When the above-mentioned anchor rod installation equipment is in use, an installation groove is opened on the top of the base, and a rotary stepper motor is fixedly installed on the bottom wall of the installation groove. However, when installing the anchor rod, it is inconvenient to adjust the direction and angle of the anchor rod, and additional time and labor are required to reposition or reinstall the anchor rod, which will directly affect the construction progress.
