Problems solved by technology
[0003] Among them, manual installation is labor-intensive, poor in safety and low in efficiency
[0004] The use of mechanical arms for installation can reduce the labor intensity of the operator, but the mechanical arm can only be installed with one arch frame at a time. During installation, the arm frame needs to be frequently operated, and the arm frame needs to be pitched and rotated many times. The telescopic action can complete the installation of multiple arches
Due to the narrow environment of the tunnel, the operation is difficult, and when using the mechanical arm to dock the arch frame, the accuracy is low, the docking time is more expensive, and the supporting speed is slow, which is not conducive to quickly closing the surrounding rock
[0005] At the same time, the above two technologies need to install the arch frame close to the working face, and the assembly of the arch frame cannot be carried out in parallel with drilling and blasting, which increases the cycle time of the process

The invention discloses an arch frame mounting device for arch frame pre-assembly and a use method thereof. The arch frame mounting device for arch frame pre-assembly is used for splicing a main arch frame section and an auxiliary arch frame section into an arch frame, the position of the main arch frame section is adjusted through an arch frame lifting device and a first arch frame supporting mechanism, the position of the auxiliary arch frame section in the height direction is adjusted through a left side second arch frame supporting mechanism and a right side second arch frame supporting mechanism, so that the auxiliary arch frame section and the main arch frame section move relatively away from each other till the end of the auxiliary arch frame section can be attached to the end of the main arch frame section, and then the main arch frame section and the auxiliary arch frame section are connected together. According to the structure, the main arch frame section and the auxiliary arch frame section do not need to be manually adjusted, so that the labor intensity of an operator can be reduced. In addition, the invention further discloses the use method of the arch frame mounting device for arch frame pre-assembly.
Description
technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a pre-assembled arch mounting device and a method for using the arch. Background technique [0002] During the excavation of the tunnel, arches need to be installed for support to improve the stability of the surrounding rock. Most of the existing arches are spliced and connected section by section, and the installation of the existing arches is mainly through manual installation with the help of a platform or the mechanical arm installation of a trolley. [0003] Among them, manual installation is labor-intensive, poor in safety, and low in efficiency. [0004] The use of mechanical arms for installation can reduce the labor intensity of the operator, but the mechanical arm can only be installed with one arch frame at a time. During installation, the arm frame needs to be frequently operated, and the arm frame needs to be pitched and rotated many times. The teles...
