Embodiment Construction

[0014] The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments, and the following embodiments do not constitute a limitation of the present invention.

[0015] like figure 1 As shown, the infrared guiding system of the present invention includes a guiding drill bit 1, an infrared light target 2, a tracking monitoring system and a display device.

[0016] The pilot drill bit 1 is a drilling tool with a sharp head, and its structure is various, but it still belongs to the common knowledge of those skilled in the art, so it will not be repeated here.

[0017] The infrared light target 2 is used for infrared sensing with the total station 3 to monitor the structure of the displacement or angle of the drill bit in real time. The infrared target 2 and the pilot drill 1 are connected by a bolt assembly. Specifically, the infrared target 2 is provided with external threads, and the pilot d...

Abstract

The invention discloses an infrared guidance system, which comprises a guide drilling bit, an infrared target, a tracking monitoring system and a display device, wherein the guide drilling bit and the infrared target are detachably connected, the infrared target and the tracking monitoring system are in infrared sensing connection, and the tracking monitoring system and the display device are connected by a data line. The guide drilling bit and the infrared target are connected by a bolt assembly. The tracking monitoring system comprises a fixing support, a total station and a camera, the total station is arranged on the fixing support, the camera is arranged on the total station, the total station is used for tracking and monitoring a distance or an angle of the infrared target, the camera is used for recording the path trace of the infrared target, and the camera and the display device are connected by a data line. The infrared guidance system has high precision, guide error within 100 m is only 3 cm, and the precision of the infrared guidance system is largely higher than that of a geomagnetic guidance device; the structure is designed scientifically and reasonably, and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of mining equipment, and in particular relates to an infrared guidance system used in the non-excavation industry. Background technique [0002] In the construction of trenchless horizontal directional drilling, the most important construction process in the construction is the direction control construction of the pilot hole. The existing wired direction control technology basically has no technical problems in the direction control construction of any distance and general interference, but in the long-term The distance cannot be tracked and positioned. Therefore, the industry has developed geomagnetic guidance equipment, whose signal transmission is not limited by length, and is widely used in large-scale crossing projects. Its working principle is to determine the line orientation between two points by the earth's magnetic field, and the control personnel send instructions to the driller according to the...
