Problems solved by technology

[0005] Both of these two patent applications disclose the use of sensors to measure the rotation angle, but neither of these patent applications discloses the specific assembly method of the angle sensor and the working machine, nor discloses the installation method of the sensor and the central rotary joint on the rotary drilling rig
Moreover, the angle sensor and its installation accessories in this patent application are not strong in anti-electromagnetic interference, which leads to the problem of instability in the angle sensor used in the working machine

Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings.

[0035] figure 1 As shown, the upper platform 1 of the rotary drilling rig is connected to the lower vehicle through the slewing support, and the high-pressure hydraulic oil acts on the slewing motor to drive the reducer to mesh the gear shaft with the ring gear of the slewing bearing, driving the upper vehicle to achieve 360° rotation. A central rotary joint is installed in the center of the upper platform 1. The central rotary joint consists of a shell 2 and a core 4; On the upper side, when the shell 2 rotates with the platform of the upper vehicle, it forms a relative rotation with the core 4 fixed on the mounting flange 3 of the lower vehicle which does not rotate.

[0036] figure 2 As shown, the rotation angle sensor element and socket 5 are embedded in the upper end of the sensor fixed joint 6 and made into an integral joint. The sensor fixed joint 6 is a hexa...

Abstract

The invention provides a real-time detection method for the rotation angle of a rotary drilling rig. The real-time detection method includes using a rotation angle detection device of the rotary drilling rig. The rotating parts and the fixed parts directly or indirectly fixed on the core of the central rotary joint, the shell of the central rotary joint is fixed on the boarding platform of the rotary drilling rig and rotates accordingly, and the core of the central rotary joint is installed by getting off the car The blue is fixed on the car of the rotary drilling rig; the rotating parts include angle sensor elements, sockets and sensor fixing joints; the fixed parts include cylindrical magnetic heads, fixed copper nuts and support rods; the rotary drilling rig in the real-time detection method of the present invention rotates The angle detection device has a simple structure, is convenient to install, and does not occupy space. Due to its small size and low requirements for installation concentricity, it has higher reliability for rotary drilling rigs working in harsh environments.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a detection device and a real-time detection method of the rotation angle of an upper vehicle platform used for drilling positioning of a rotary drilling rig. Background technique [0002] Rotary drilling rig is a kind of building pile foundation construction equipment that borrows soil to form holes. The loading platform of the rotary drilling rig provides various system layout spaces and working device installation platforms for the rotary drilling rig, and is the core component of the rotary drilling rig. The upper platform of the rotary drilling rig is connected to the lower vehicle through the slewing support, and the high-pressure hydraulic oil acts on the rotary motor to drive the reducer to make the gear shaft engage with the ring gear of the slewing bearing, which drives the upper vehicle to achieve 360° rotation; the rotation center of the upper platform Equipped w...
