Embodiment
[0032] see Figure 1-6 , in order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a support device for tunnel construction, including vertical beams 1, also includes an arched mounting frame 2, which is convenient to form a passage space after the installation of the support device for tunnel construction is completed, thereby reducing The impact on the construction equipment entering and leaving the tunnel is relatively small. The vertical beam 1 is fixedly connected in the arched mounting frame 2, which is convenient to form the main support structure of the tunnel, and the support is relatively firm. The arched mounting frame 2 is slidably connected with two sides. The arc-shaped block 3 is convenient for the connection between the side support beam 4 and the arch-shaped mounting frame 2, so as to improve the completeness of the supporting device for tunnel construction, and the probability of losing parts during tran...

The invention relates to the technical field of support devices, in particular to a support device for tunnel construction, comprising a vertical beam and an arch-shaped mounting frame, wherein the vertical beam is connected in the arch-shaped mounting frame, and the arch-shaped mounting frame is connected with two side arc blocks , the two side arc blocks are connected with side support beams, the two side support beams and the vertical beam are connected with a folding mechanism, the arched mounting frame is connected with two electric fine-tuning rods, and the two electric fine-tuning rods are connected to each other. A support plate is connected, a countersunk head hole is opened on the support plate, a locking pin mechanism is installed in the countersunk head hole, the bottom ends of the two electric fine-tuning rods are connected with a support frame, and the support frame is connected with a stable foot plate, and the stable foot plate There is a through hole matching with the locking pin mechanism on the upper part. The installation and use process and the disassembly construction process are relatively convenient, the workload is small, and the practicability is good. In the process of use, the impact on the tunnel construction equipment entering and leaving the tunnel is small. The construction impact is small, the transportation is more convenient, the probability of missing parts is low, and the complete set is better.
Description
technical field [0001] The invention relates to the technical field of support devices, in particular to a support device for tunnel construction. Background technique [0002] As we all know, the support device for tunnel construction is an auxiliary device used for tunnel support in the process of tunnel construction, so as to make the tunnel construction safer, and it has been widely used in the process of tunnel construction. [0003] The existing support device for tunnel construction includes arched steel beams and a plurality of vertical beams, the plurality of vertical beams are fixedly connected to the arched steel beams through fixing bolts, and the bottom ends of the plurality of vertical beams are welded with support seats. A tie rod is fixedly connected between every two adjacent vertical beams in the vertical beam by connecting bolts. When in use, the vertical beam and the tie rod are fixedly connected by connecting bolts, and then the arched steel beam and the...
