Abstract

The embodiment of the invention provides a depth sounding system used for a rotary drilling rig. The rotary drilling rig comprises a drill. The depth sounding system comprises a bearing block, a winding drum, a rope, a rotary coder and a processing unit, wherein the winding drum comprises a winding drum main body and a winding drum output shaft and is arranged in the bearing block through a first bearing; one end of the rope is fixed on the winding drum main body and the other end is connected with the drill of the rotary drilling rig; a shell of the rotary coder is fixed on the bearing block, and an input shaft of the rotary coder is fixedly connected with the winding drum output shaft; and the processing unit is used for receiving an angle measured by the rotary coder and converting the angle into the length value of the rope according to the angle. In the invention, because the winding drum is arranged on the bearing block through the bearing, a slipping phenomenon cannot be generated, and moreover, the winding drum is directly wound with the rope and is not easy to abrade, therefore, the use precision cannot be affected after the winding drum is used for a long time. The embodiment of the invention also provides a rotary drilling rig equipped with the depth sounding system.

Description

technical field [0001] The invention relates to a construction machine, more specifically, to a rotary drilling rig and a sounding system. Background technique [0002] Rotary drilling rig is a construction machine suitable for hole-forming operations in building foundation engineering. It is mainly suitable for the construction of sandy soil, cohesive soil, silty soil and other soil layers, and is widely used in various foundation constructions such as cast-in-place piles, diaphragm walls, and foundation reinforcement. [0003] The rotary drilling rig needs to know the depth of the hole and the position of the drill bit at any time during construction. In order to improve the reliability of the rotary drilling rig, most of the rotary drilling rigs are currently equipped with a depth measurement system, such as figure 1 As shown, the sounding system includes: a sensor 11, a gear plate 12, a pulley frame 13, a shaft 14, a wire rope 15 and a pulley 16, the gear plate 12 and t...
