Embodiment 2

[0059] A method for erecting a multi-arch arch, using the multi-functional arch trolley in Embodiment 1 to erect a multi-arch arch, comprising the following steps:

[0060] Step 1: Make a multi-arch frame: Arrange two or more folded arch frames in parallel, and then connect them with several strengthening connecting rods to form a multi-arch frame;

[0061] Step 2: Fold the multiple arches on the support fixture 600: place the support fixture 600 under the top arch section, and control the support fixture 600 to lift the top arch section to a certain height through the main arm frame 200. The left arch section and the right arch section are symmetrically folded towards the inner side of the top arch section; when the support fixture 600 is slowly lowered through the main boom 200, the left arch section and the right arch section gradually move toward the top arch section. The inner side of the arch is folded until the folding of the multi-arch arch frame is completed; the left...

Abstract

The invention belongs to the field of tunnel construction, and discloses a multifunctional arch support trolley. The trolley comprises a trolley body. A main arm frame, a right auxiliary arm frame anda left auxiliary arm frame which the rotation and stretchable functions are arranged on the trolley body. The main arm frame is located between the right auxiliary arm frame and the left auxiliary arm frame. A support clamp for clamping / supporting arch supports is arranged at the end of the main arm frame, and a rotation mechanism is arranged in the support clamp so as to control the arch supports to rotate; the ends of the right auxiliary arm frame and the left auxiliary arm frame are each provided with a worker operation platform. The multifunctional arch support trolley can transport folded steel arch supports into the tunnel stably, and perform direct changes inside the tunnel, meanwhile after the arch supports are transported to a preset place inside the tunnel, the folded steel archsupports can be safely, rapidly and stably lifted to the preset height, and the operation requirement for multi-step long-distance lifting is met.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a tunnel arch erection device. Background technique [0002] In recent years, my country's underground engineering has developed rapidly, and mechanized operations have gradually been widely used in engineering technology, especially in the field of underground tunnel construction. [0003] At present, in the process of tunnel construction, steel arches need to be erected on the excavated rock face. The traditional steel arches are heavy, and the installation of the arches is mainly carried out by manpower. It has the following disadvantages: 1. The number of workers required is large, and the labor intensity Large size and low efficiency. Existing arches are mostly connected by flanges and sleeves. When on-site installation requires a lot of manual construction; 2. Existing arch constructions cannot cooperate with mechanized on-site construction of arches. [0004] ...
