Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tunnel engineering equipment, more particularly to the technical field of an arch frame transfer platform and method. BACKGROUND

[0002] In the prior art, the transfer and installation of the integrated machine mainly adopts the folding prefabricated arch frame. Due to the parallel process and the limitation of the space in the hole, if the total arc length of the folding arch frame is designed to be consistent with the total arc length of the initial support section of the upper tunnel, the two side segments of the folding arch frame cannot be fully unfolded and delivered to the support surface in the hole. If the total arc length of the folding arch frame is designed to be smaller than the total arc length of the initial support section of the upper tunnel, the folding arch frame can be unfolded, but since the total arc length of the arch frame is smaller than the total arc length of the support, after the folding arch frame is fully unfolded, the total length of the arch frame does not reach the total arc length of the support of the upper tunnel. Therefore, the arch foot position of the previous process needs to be left with soil support, and the soil on both sides needs to be removed in the subsequent process, and a small support leg arch frame needs to be added to reach the total arc length of the support. This increases the process time of excavation and support, reduces the efficiency, and increases the cost.

[0003] In addition, in the current technology, a loader is used to transport the segmented arch frame to the working face segment by segment, and the segmented arch frame is grabbed by the middle and both side vertical arch jib frames segment by segment to erect the arch frame. The transfer of the arch frame in this technology mainly relies on manual operation or simple mechanical assistance, which has the following defects:

[0004] Low transfer efficiency: in this technology, the arch frame is transported to the working face segment by segment, and is spliced in the tunnel working face. The arch frame needs to be transported multiple times, which reduces the construction efficiency. Moreover, the arch frame transfer operation cannot be parallel with the hole deslagging, and the arch frame transfer will affect the deslagging channel. The arch frame needs to be placed in the state of no deslagging in the working face. After the deslagging is completed, the arch frame transfer is performed. SUMMARY

[0005] The present application aims to solve the above technical problems by providing an arch frame transfer platform and method. The whole arch frame is transferred in segments. The arch frame is divided into three segments. The middle segment of the arch frame is transferred from the ground to the upper part of the rack and placed on the arch frame storage rack, and is grabbed by the middle vertical arch jib frame to the working face. The two side segments of the arch frame are transferred from the side of the rack by using the side space and the side arch frame transfer grabbing assembly, and are grabbed by the side vertical arch jib frame to the working face. This technology uses the upper and side space of the rack to store the three segments of the arch frame, does not affect the deslagging channel, can be parallel with other processes, and saves the operation time. The three segments of the arch frame are spliced and installed if the arch frame installation is performed.
