Problems solved by technology

[0005] In short, none of the existing arching machines can realize the full working conditions (full section, two steps, three steps) and the whole process (transportation of arches on vehicles, butt jointing of arches, hanging steel mesh, welding transverse bars, anchors) for the installation of tunnel arches. The drilling and installation of rods and advanced small conduits) construction, and low efficiency, which seriously restricts the use of arching machines in tunnel construction. So far, there is no equipment in China that can really satisfy the installation and construction of tunnel arching

Embodiment Construction

[0036] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0037] Such as figure 1 As shown, a multi-functional tunnel rock drilling frame-arch integrated machine provided by the present invention is mainly composed of a chassis 1, a host platform 2, a supporting arch device 4, a jib 6, and outriggers 7. Chassis 1 is a wheeled chassis, four-wheel drive, has faster traveling speed and better climbing ability. On the main engine platform 2, hydraulic pressure, electric control, power system and other auxiliary systems are arranged, and the main engine platform 2 is arranged with outriggers 7 to maintain the stability of the whole vehicle and avoid tipping during the construction of the arch machine. The arm frame 6 is installed on the host platform 2 through the swivel seat 5, and there are two arm frames 6 with similar structures, which are arranged at the rear of the host platform 2. The supporting arch devic...

Abstract

A multi-function tunnel rock drilling and arching all-in-one machine comprises a host platform (2) which is arranged on a basal disc (1); two arm frames (6) are arranged at the rear portion of the host platform by a rotation seat (5), and the arm frames can be folded and stored in a driving or static state; the front end of a forearm is rotationally provided with an arch grabbing device (18), a rock drilling device (19), a manned platform (24), and a truck crane (23). The multi-function tunnel rock drilling and arching all-in-one machine can perform the arch support operation during full section, two-step and three-step excavating of a tunnel. Through the coordination of the two arm frames and the above working devices, the arch frame transported by car, the installation of the arch, the hanging of the reinforcing mesh, the welding of the transverse reinforcement and the installation of a bolt and a drill hole of leading small tube can be realized; the efficiency is far higher than that of the manual operation.

Description

technical field [0001] The invention relates to engineering machinery, in particular to a multifunctional tunnel rock drilling frame-arch integrated machine. Background technique [0002] In tunnel construction, when the grade of the surrounding rock is poor, arch support is often required to improve the stability of the surrounding rock. [0003] Existing arch machine generally has two arms, is equipped with one or two hanging baskets, and the arm frame is generally a two-section telescopic arm. Since the arm frame cannot be folded, the manipulator at the front end of the arm frame cannot extend into the inside of the three steps of the tunnel to install the arch frame. However, the arch support of the three steps is very common in actual construction, so it is still necessary to manually carry out the three steps. Arch support. In addition, after the arch frame is installed, the anchor bolts and system anchor rods need to be installed. If the surrounding rock is poor, it...
