Embodiment Construction

[0019] The structure of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but it is not intended as a limitation of the present invention.

[0020] Such as Figure 1~3 As shown, the present invention discloses a docking fine-tuning device for tunnel steel arches. Specifically, the docking fine-tuning device includes: a U-shaped card slot 1, a clamping steel plate 3, a fine-tuning screw 4, and a handle; the U-shaped card slot 1 includes Top plate, bottom plate and the side plate that top plate and bottom plate are connected together, and the central position of this bottom plate is provided with the threaded hole that matches with fine-tuning screw rod 4; The internal thread of the external thread and the threaded hole is matched and positioned), and the end of the fine-tuning screw 4 positioned above the base plate is fixed with a top tight steel plate 3, and the end of the fine-tuning screw 4 position...

Abstract

The invention relates to the technical field of tunnel construction, in particular to a tunnel steel arch frame butt joint fine adjusting device. A threaded hole matched with a fine adjusting screw isformed in a bottom plate of a U-shaped clamping groove, the fine adjusting screw penetrates through the bottom plate of the U-shaped clamping groove through the threaded hole, a jacking steel plate is fixed to the end, located above the bottom plate, of the fine adjusting screw, a handle is fixed to the end, located below the bottom plate, of the fine adjusting screw, thus, in the butt joint process of tunnel I steel, the two pieces of butt joint I steel are finely adjusted and aligned by clamping the I steel by the fine adjusting screw through the jacking steel plate and the U-shaped clamping groove, thus, an I steel butt joint opening can be finely adjusted rapidly, the butt joint fine adjusting efficiency of steel arch frames is improved, the phenomenon of butt joint dislocation of theI steel is avoided, the butt joint quality of the steel arch frames is improved, precise butt joint of the steel arch frames is achieved, then the construction efficiency is improved, the labor costis reduced, and the device is low in weight, convenient to move and high in practicality.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a butt fine-tuning device for tunnel steel arch frames. Background technique [0002] At present, when making and welding tunnel steel arches, it is necessary to butt the end faces of the steel arches at both ends. The steel arch frame generally adopts I-beams. In order to ensure the accuracy of the I-beam butt joint process, it is generally adjusted manually on the feeding platform, and then the joint is calibrated manually with a crowbar. However, due to the heavy weight of each section of the I-beam, it is extremely difficult to manually accurately correct the butt joint of the I-beam, the end faces are not easy to be evenly connected, and the construction efficiency is low, and there are certain hidden dangers in the quality of the I-beam butt joint; Unwanted to see. Contents of the invention [0003] In view of the above existing problems, the present inventi...
