Description

Technical Field

[0001] The invention relates to a feeding device and a process for producing a tunnel steel arch frame, belonging to the technical field of steel arch frame production. Background Art

[0002] Steel arch frame is a support measure that uses bent I-beams to reinforce underground projects. It can be combined with anchor rods, shotcrete and steel mesh to form a composite support arch frame, which is widely used in tunnels, subways, hydropower stations, underground caverns and other projects.

[0003] During the production process of steel arches, the entire I-beam needs to be cut to a size that meets the construction requirements, and after the cutting of the entire I-beam is completed, there will inevitably be residual material. In order to avoid the waste of I-beam residual material, the I-beam residual material needs to be continued to be welded, that is, the I-beam residual material is continued to be welded with the new entire I-beam, and a reinforcing plate needs to be installed at the joint welding point to strengthen the connection strength of the two sections of I-beam at the joint welding point, improve the quality of the steel arch product, and make it meet the construction requirements.

[0004] However, when the existing steel arch frame is installed with reinforcement plates at the joint welding, the feeding of the reinforcement plates is done manually, which has low work efficiency, large workload, high labor cost, and cannot achieve continuous feeding and automatic production. Even if there is a method in the prior art that uses a conveyor line to transport reinforcement plates for robot grabbing, the conveyor line used in this reinforcement plate feeding method not only occupies a very large area, but the long conveyor line will also greatly increase the operating cost of the steel arch frame production line, increase the production and processing cost of the steel arch frame, and the conveyor line also requires manual auxiliary feeding, which cannot achieve large-scale installation of reinforcement plates.
