Abstract
The utility model belongs to the field of shield tunneling machine equipment, and particularly relates to a screw conveyer blade for a shield tunneling machine. The screw conveyer blade for the shield tunneling machine comprises a blade shaft, connecting flanges and a screw blade, wherein the connecting flanges are respectively arranged at two ends of the blade shaft, and the screw blade is fixedly sleeved on the blade shaft. The screw conveyer blade for the shield tunneling machine is characterized in that hard alloy wear-resisting nets are arranged on two side surfaces of the screw blade, and a carbonized steel bar is arranged on the edge of the screw blade. Due to the facts that the hard alloy wear-resisting nets are arranged on the two side surfaces of the screw blade in a bead weld mode and the carbonized steel bar is welded on the edge of the screw blade, sand and gravel are effectively prevented from making contact with the screw blade directly, abrasion of the screw blade is reduced, and meanwhile, the connection strength of the hard alloy wear-resisting nets, the carbonized steel bar and the screw blade is high so that the hard alloy wear-resisting nets, the carbonized steel bar and the screw blade can not be loosened and fall off easily. The screw conveyer blade for the shield tunneling machine is extrusion-resisting and wear-resisting. According to the screw conveyer blade for the shield tunneling machine, service life of a screw conveyer is prolonged, reliability of long-distance tunneling of the screw conveyer is improved, replacement frequency is reduced in the process of construction, and construction cost is lowered.
Description
Technical field
The utility model belongs to the shield machine apparatus field, relates in particular to a kind of helical feed machine part.
Background technology
Conveying worm is the important component part of supplying mud type balancing earth-pressure shielding machine, when full section sandy gravel stratum is constructed, the helical blade of conveying worm very easily weares and teares, helical blade is along with the increase of service time, its degree of wear also increases thereupon, just needs to upgrade when helical blade may wear to a certain degree.The structure of conveying worm blade, the material variety of conveying and environment for use situation have determined the application life of conveying worm.The conveying worm blade comprises sharf, helical blade, adpting flange, helical blade is parts easy to wear, in the subway construction engineering, the distance at two stations is more than 800 meters, and band presses off the storehouse maintenance in the underground tunneling process of shield machine between two stations, and the enforcement difficulty is big, the time is long, expense is high.Therefore, helical blade anti-extrusion, wear-resistant, long service life is most important to construction speed and construction cost.
Chinese patent CN101913489A discloses a kind of spiral blade of spiral conveyer, described helical blade is fixedly connected on the screw reamer steel pipe, the two ends of described screw reamer steel pipe all are provided with screw reamer end connecting flange, on the surface at the edge of described helical blade, be provided with the reinforced blade that high-abrasive material is made, described reinforced blade is fixed on the described helical blade by screw bolt and nut.This invention is provided with reinforced blade by the surface at the edge of helical blade and has strengthened its anti-wear performance, has increased the whole service life of screw machine, and is insecure but reinforced blade connects, easily loosening, safeguards inconvenient.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of shield machine conveying worm blade, comprise sharf, adpting flange, helical blade, described sharf two ends are respectively equipped with adpting flange, described helical blade is fixedly sleeved on sharf, it is characterized in that: described helical blade two sides are provided with the wear-resisting net of carbide alloy, and described helical blade edge is provided with the carbonization steel bar.
The wear-resisting net built-up welding of described carbide alloy is in the helical blade two sides.
Described carbonization steel bar is welded on the helical blade edge.
The beneficial effects of the utility model are: at the wear-resisting net of helical blade two sides pile-up welding hard alloy and at helical blade edge welding carbon steel bar, effectively avoided grit stone directly to contact with helical blade, the wearing and tearing of helical blade have been alleviated, and the bonding strength of the wear-resisting net of carbide alloy, carbonization steel bar and helical blade is big, is difficult for becoming flexible and coming off; The utility model is anti-extrusion, wear-resistant, has improved the application life of conveying worm and the reliability of long distance driving, has reduced the replacing frequency in work progress, has reduced construction cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Among the figure: 1-sharf, 2-adpting flange, 3-helical blade, the wear-resisting net of 4-carbide alloy, 5-carbonization steel bar.
At sharf 1 two ends adpting flange 2 is set respectively, helical blade 3 is fixedly sleeved on sharf 1, the wear-resisting net 4 of helical blade 3 two sides pile-up welding hard alloys, helical blade 3 edges welding carbon steel bar 5.
The above; it only is the specific embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to replacement or change according to the technical solution of the utility model and design thereof, all should be encompassed within the protection domain of the present utility model.
