Embodiment Construction

[0053] Such as figure 1 , figure 2 As shown, the present invention includes a frame, a traveling mechanism that drives the frame to move back and forth along the center line of the tunnel under construction, a traction mechanism that is connected in transmission with the traveling mechanism, and a tunnel that needs to be installed behind the frame. The arch lifting device for lifting the arches one by one and the arch transfer mechanism 2 for transferring the tunnel arches lifted by the arch lifting device to the designed installation position one by one through alignment adjustment. The arch transfer mechanism 2 includes a translation trolley that can move back and forth on the upper part of the frame, a lifting mechanism that can smoothly lift the tunnel arch, and a horizontal movement that can move left and right on the translation trolley. Simultaneously drive the left and right moving mechanism of the lifting mechanism to move left and right synchronously, the upper par...

Abstract

The invention discloses a tunnel arch center installation operation vehicle. The tunnel arch center installation operation vehicle comprises a machine frame, a travelling mechanism, a traction mechanism, an arch center lifting device for lifting tunnel arch centers which are arranged on the rear part of the machine frame and are needed to be installed one by one, and an arch center transferring mechanism for transferring the arch centers which are lifted by the arch center lifting device one by one through alignment and adjustment; the arch center transferring mechanism comprises a translating trolley which can move forward and backward on the upper part of the machine frame, a lifting mechanism for stably lifting the tunnel arch centers, and a left and right movement mechanism for driving the lifting mechanism to synchronously move left and right; and the translating trolley, the left and right movement mechanism, and the lifting mechanism align and adjust the tunnel arch centers front and back, right and left and up and down respectively. The tunnel arch center installation operation vehicle has a reasonable design, is convenient to assemble, and easy and convenient to operate, safe and reliable in working performance, and good in a using effect, and can solve the problems of large working difficulty in movement and accurate positioning of steel arch centers after lifting during the installation of the conventional steel arch centers, low installation efficiency, large labor intensity and the like.

Description

technical field [0001] The invention belongs to the technical field of tunnel support structure construction, and in particular relates to a tunnel arch installation operation vehicle. Background technique [0002] With the development of national infrastructure construction, the infrastructure construction market is booming, and roads and railways are realizing leapfrog development, among which tunnel construction is an important part of road and railway construction. In the process of tunnel construction, there are often practical problems such as insufficient foundation bearing capacity in the process of new stress formation due to lack of solid foundation support, which leads to tunnel instability and collapse, which seriously affects the safety of people and equipment. hindered the progress of construction. In the actual construction process, in order to solve the above-mentioned practical problems such as tunnel instability and landslides, it is necessary to quickly a...
