Embodiment Construction

[0033] Attached below Figure 1 to Figure 5 The present invention is described further:

[0034] In this embodiment, the roadheader is provided with 3 sections of barrels, in which the middle section and the rear section are respectively processed with 3 annular grooves (the number of annular grooves can be determined according to the diameter of the barrel wall of the roadheader and the shape of the resistance block. number of blocks), and a resistance increasing device is installed in each annular groove, and each resistance increasing device is formed by overlapping 14 resistance increasing parts along the circumference of the cylinder. Each resistance-increasing component includes a bottom plate, a lap plate 9 fixed on the side of the bottom plate, a resistance-increasing block 8 welded on the surface of the bottom plate, a shaft is fixed at one end of the bottom plate, and a hook 12 is fixed in an annular groove on the outer wall of the cylinder. , the shaft of the resis...

Abstract

The invention relates to a resistance-enhancing component on the periphery of a barrel body of a self-drive excavating machine, belonging to the trenchless construction field of laying underground pipelines. Annular grooves with identical structures are respectively processed on the periphery of each section of barrel body of the excavating machine, and resistance-enhancing rings with identical structures are distributed in each annular groove. Each resistance-enhancing ring is formed by lapping the resistance-enhancing components along the periphery of the barrel body, and the resistance-enhancing component comprises a bottom plate, a lap plate fixed on the side face of the bottom plate and a resistance-enhancing block fixed on the surface of the bottom plate; and a shaft is fixed at one end of the bottom plate, a hanging hook is fixed in the annular groove on the external wall of the barrel body, the shaft of the resistance-enhancing component is arranged in the hanging hook and can rotate therein, the resistance-enhancing components of each ring of resistance-enhancing device are lapped with one another by the bottom plates and the lap plates, and a supporting device is arranged between the resistance-enhancing ring and the barrel body. The resistance-enhancing component not only can endue the self-drive excavating machine with the function of long-distance self-drive excavation in the earth but also can be matched with the self-drive excavating machine to realize the highly demanded function of curve turning which can not be found in the existing trenchless technology.

Description

technical field [0001] The invention relates to a resistance-increasing component around the cylinder body of a self-propelled tunneling tunnel boring machine, belonging to the construction field of trenchless underground pipeline laying. Background technique [0002] Currently widely used trenchless construction techniques, such as shield method and pipe jacking method, have exposed some limitations and deficiencies, such as the limitation of advancing length and turning flexibility, etc. These limitations make urban underground pipeline network construction and underground Space development is getting more and more difficult. The emergence of self-propelled tunnel pipeline construction technology and corresponding excavation equipment has overcome these difficulties. [0003] The principle of the self-propelled tunnel boring machine is to use the multi-circle resistance increasing blocks arranged on the outer circumference of the tunnel boring machine to tighten the surro...
