Description

Technical Field

[0001] The invention relates to the technical field of tunnel engineering, and in particular to an anchor bolt installation trolley and method for separating drilling and installation. Background Art

[0002] At present, the main installation forms of anchor rods are divided into two forms: manual installation and mechanical installation. Manual installation often uses a tunnel drilling rig to drill holes, and then uses the drilling rig basket to manually push anchor rods and perform grouting operations. This construction method has certain safety hazards. The tunnel has just been blasted and a safety support system has not yet been fully formed. Personnel are easily injured by falling rocks during installation operations near the face.

[0003] With the advancement of technology, the existing anchor construction has achieved mechanization of the entire process of drilling, anchoring and grouting to a certain extent. Chinese patent CN117365595A discloses an anchor trolley and working method for a complete set of anchor support that can realize drilling, anchoring and grouting. The anchor trolley can replace manual installation of anchors and integrate the drilling, anchoring and grouting functions to a certain extent, thereby improving the construction efficiency. However, in the actual anchor construction process of the tunnel, the functional modules are integrated on one boom, resulting in a complex structure, inconvenient operation, uncontrollable failure rate, and limited single-arm construction efficiency to a certain extent, resulting in low efficiency in moving vehicles for large-section tunnel construction.

[0004] Chinese patent CN113669093A discloses an anchor arm precision guiding system and an anchor trolley using the system, which realizes the simultaneous operation of drilling and anchor installation, avoids the step-by-step implementation of drilling and anchor installation in traditional mechanisms, and reduces the complexity of operation to a certain extent. However, only one anchor can be constructed at a time. After each anchor is installed, the arm needs to return to the ground for anchor loading operations, which takes up a lot of construction time. In addition, it is limited to mortar anchor construction, and the construction scope is limited.

[0005] Chinese patent CN211081696U provides an anchor trolley, which solves the structural complexity problem of the traditional integrated drilling, anchoring and grouting arm, while retaining the hanging basket structure to assist in the operation. However, the installation of anchors still relies on manual insertion of anchors one by one into the propulsion mechanism for installation. There is a risk of falling during the transfer process, and the number of rod warehouses on the hanging basket is limited. The applicable anchor length is also affected by the size of the hanging basket. Anchor alignment is mainly carried out by personnel adjusting the hanging basket and the propulsion beam posture, which is inconvenient to operate and restricts construction efficiency.

[0006] In summary, there is an urgent need for a trolley that can improve the efficiency of drilling and anchor installation construction to solve the problems existing in the prior art. Summary of the invention
