Problems solved by technology

The direction adjustment technology is the key to ensure that the construction of the open full-face rock roadheader is carried out according to the design route. During the turning process, there is a slight difference in the advancing angle of the cutter head of the roadheader, and the roadheader will move away from the predetermined track. The structure of the direction adjustment device itself is complicated. The correct grasp and precise control of the steering device is still a major technical difficulty, and it has not been fully grasped and applied in China

Abstract

The invention discloses a direction-adjusting device for an open-type full-section hard rock tunneling machine. The direction-adjusting device comprises a main beam, two support boots and a saddle tree, wherein guide rails are arranged on the two sides of the main beam; the two support boots are positioned on the two sides of the main beam; an upper support boot oil cylinder and a lower support boot oil cylinder are arranged on each support boot through a spherical hinge; an upper support boot oil cylinder shaft and a lower support boot oil cylinder shaft are respectively connected between the upper support boot oil cylinders and the lower support boot oil cylinders of the two support boots; the saddle tree is arranged on the guide rails and can move forwards and backwards relative to the guide rails; the two sides of each upper support boot oil cylinder are hinged with the saddle tree by torque oil cylinders; and the upper support boot oil cylinder shaft is connected with the saddle tree through a mutually rotated cross pin shaft structure. After adopting the direction-adjusting device, the open-type full-section hard rock tunneling machine can realize horizontal, vertical and torsion control and adjustment in a tunneling process of the tunneling machine rapidly, accurately and reliably.

Description

technical field [0001] The invention belongs to a mechanical device, in particular to a device for adjusting the forward direction during the working process of an open-type full-section hard rock tunneling machine. Background technique [0002] The open full-face hard rock tunnel boring machine (abbreviated as TBM) is a large-scale tunneling equipment that integrates hydraulic, control, electromechanical and other technologies, and is widely used in the construction of various tunnels in hard rock geology. The tunnel design includes uphill, downhill, and left-right turning sections. Under the overall cooperation of various sub-components, the roadheader realizes the fine-tuning of the cutter head structure up and down, left and right directions through the direction adjustment device, so as to drive the whole machine to adjust the forward direction and ensure The construction is proceeding normally according to the design route. The cutter head of the roadheader rotates w...
