Description

Technical Field

[0001] The present invention relates to the technical field of tunnel engineering equipment, and more specifically to the technical field of an arch frame transfer platform and method. Background Art

[0002] In the current existing technology, the integrated unit mainly adopts the transportation and installation of folding prefabricated arch frames. This folding prefabricated arch frame is limited by the parallel process and the space in the tunnel: 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 road, the two side sections of the folding arch frame in the tunnel cannot be fully unfolded and sent to the support surface. If the folding arch frame is designed to have a total arc length less than the total arc length of the initial support of the upper section, then the folding arch frame can be unfolded, but because the total arc length of the arch frame is less than the total support arc length, after the folding arch frame is fully unfolded, the total length of the arch frame does not reach the total support arc length of the upper road. This results in the need to leave soil piles at the arch foot position of the previous process for support, and in the subsequent process, the soil piles on both sides need to be excavated, and then a small leg arch frame is added to reach the total support arc length. This increases the process time of excavation and support, reduces efficiency, and increases costs accordingly.

[0003] In addition, in the current technology, a loader is used to transport the segmented arch frame to the tunnel face one by one, and then the middle and two side arch arms of the integrated unit are used to grab the arch frame one by one for erection. The transportation of this arch frame mainly relies on manual or simple mechanical assistance, and has the following defects:

[0004] Low transfer efficiency: In this technical route, the arch frame is transported to the tunnel face in sections and spliced ​​at the tunnel face in the tunnel. It needs to be transported multiple times, and the construction efficiency is low. In addition, the arch frame transfer operation in this technical route cannot be synchronized with the slag discharge in the tunnel. The arch frame transfer will affect the slag discharge channel, and the arch frame needs to be placed on the tunnel face without slag. After the slag discharge is completed, the arch frame transfer can be carried out. Summary of the invention

[0005] The purpose of the present invention is to solve the above-mentioned technical problems, and the present invention provides an arch frame transfer platform and method. The whole arch frame is transferred in sections. And it is divided into three sections. For the middle arch frame, the middle segmented arch is transferred from the ground to the platform, and placed on the arch frame transfer rack, and grabbed to the face through the middle vertical arch arm. For the segmented arch frames on both sides, by utilizing the side space, a side arch frame transfer grab arm assembly is designed to transfer the segmented arch frames on both sides from the side of the platform, and grab to the face through the side vertical arch arm. This technical route utilizes the upper and side spaces of the platform to store three-section segmented arch frames, does not affect the slag discharge channel, can be operated in parallel with other processes, and saves working time. If the arch frame is installed, the three-section segmented arch frame is spliced ​​and installed.

[0006] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0007] The first aspect of the present invention provides an arch frame transfer method, which is a transfer scheme for a side arch frame, and the specific steps are as follows:

[0008] S1. Use a cantilever crane to lift the side arch frame to an upright state, and then adjust the posture of the side arch frame to the curvature posture of the tunnel section through the lifting mechanism device;

[0009] S2, the arch frame transfer assembly slides to the bottom of the side arch frame, the cantilever crane lowers the side arch frame, and the side arch frame is obliquely hung on the upper beam hook plate of the arch frame transfer assembly, and then the side arch frame is transferred to the side arch frame transfer grab arm assembly through the sliding of the arch frame transfer assembly itself and the two-stage swing cooperation with the lifting mechanism device;

[0010] S3. The side arch frame is grasped by the gripper assembly and slid to the front end of the track, and handed over to the side arch assembly. The side arch assembly grasps the side arch frame and transports it to the tunnel face.

[0011] The specific steps for the transfer plan of the middle arch are as follows:

[0012] A1. The lifting mechanism device lifts the middle arch frame vertically to a position that matches the total height of the arch frame transfer rack;

[0013] A2. The two arch frame transfer rack assemblies designed on both sides of the platform slide forward and backward to the bottom of the middle arch frame. The lifting mechanism lowers the middle arch frame and places the middle arch frame on the two arch frame transfer assemblies.

[0014] A3. The middle arch frame is then transferred to the platform through the sliding movement of the arch frame transfer assembly. Since the sliding travel of the arch frame transfer assembly is limited, the middle arch arm frame is pitched and lifted up, so that the cardboard on the middle arch arm frame clamps the middle arch frame;

[0015] A4. The middle arch frame is transferred to the front section of the upper beam of the arch frame transfer assembly through the sliding movement of the middle arch arm frame itself, so that after the middle arch frame slides back, the front end gripper component of the middle arch arm frame can grab the middle arch frame and transfer it to the face.

[0016] The two-stage swing of the lifting mechanism is realized by the primary L-shaped swing arm assembly and the secondary L-shaped swing arm assembly. The primary L-shaped swing arm assembly is assembled to the vertical lifting assembly through rollers, and driven by the hydraulic motor and the operation of the sprocket chain assembly, the primary L-shaped swing arm assembly is driven to move up and down in the vertical lifting assembly.

[0086] This embodiment provides an arch transport method, and the specific steps are as follows:

[0087] S1, one end of the side arch frame is first put on the ground, and the other end is hoisted by a cantilever crane, so that the side arch frame is gradually in an upright state, and then the posture of the side arch frame is adjusted to the curvature posture of the tunnel section through the lifting mechanism device 200;

[0088] S2, the arch frame transfer assembly slides to the bottom of the side arch frame, the cantilever crane lowers the side arch frame, and the side arch frame is obliquely hung on the upper beam hook plate of the arch frame transfer assembly, and then the side arch frame is transferred to the side arch frame transfer grab arm assembly 600 through the sliding of the arch frame transfer assembly itself and the cooperation with the first-level L-shaped swing arm assembly 220 and the second-level L-shaped swing arm assembly 230 of the lifting mechanism device 200;
