Embodiment 1

[0022] Embodiment 1, a kind of intelligent spraying system, such as figure 1 and image 3 As shown, it includes a gunite bridge 1 arranged along the axial direction of the tunnel. A rotary device is arranged in the circumferential direction of the gunite bridge 1. The rotary mechanism of the rotary device is connected with a spraying manipulator, and the spraying manipulator is provided with a spraying nozzle. 4. The slewing device can drive the spraying manipulator to rotate along the inner ring surface of the tunnel through the slewing mechanism. The spraying manipulator can expand and contract while rotating with the slewing device. The spraying nozzle 4 on the spraying manipulator can follow the action of the spraying manipulator. Convenient grouting on the inner ring surface of the tunnel.

[0023] The gunite bridge 1 is provided with a multi-degree-of-freedom three-dimensional scanner group connected to the measurement and control center, the rotary device, the gunite ...

Embodiment 2

[0026] Embodiment 2, a kind of intelligent spraying system, such as figure 2 As shown, the point C in the figure is the scanning area. There are two first multi-degree-of-freedom three-dimensional scanners 5-1 and second multi-degree-of-freedom three-dimensional scanners 5-2, and the two first multi-degree-of-freedom three-dimensional scanners 5-1 are symmetrically arranged on the gunite bridge On the left and right sides of 1, two second multi-degree-of-freedom three-dimensional scanners 5-2 are symmetrically arranged on the left and right sides of the shotcrete bridge 1, which can not only effectively improve the scanning efficiency, but also ensure the integrity of the scanning area, avoiding the use of The problem of high cost caused by an overly complex multi-degree-of-freedom 3D scanner.

[0027] Other structures of this embodiment are the same as those of Embodiment 1.

Embodiment 3

[0028] Embodiment 3, a spraying support method of an intelligent spraying system, comprising the following steps:

[0029] Step 1: three-dimensional scanning, the measurement and control center controls the first multi-degree-of-freedom three-dimensional scanner 5-1 to scan the contour of the inner annulus of the tunnel, and returns the scanned image data to the measurement and control center;

[0030] Step 2: automatic first spraying, the measurement and control center automatically controls the first rotary device 2-1 to output a matching rotary speed according to the scanned image data in the first step, and automatically controls the first spraying manipulator 3-1 to drive the spray nozzle 4 Facing the matching injection direction, and then controlling the first rotary device 2-1 to drive the nozzle 4 on the first spraying manipulator 3-1 to spray the inner ring surface of the tunnel for the first time;

[0031] Step 3: Scanning detection, the measurement and control cente...

Abstract

The invention discloses an intelligent spouting system. The intelligent spouting system comprises a spouting bridge which is arranged in an axial direction of a tunnel, wherein a rotary device is arranged in the peripheral direction of the spouting bridge; a spouting mechanical hand is connected on a rotary mechanism of the rotary device; a spouting nozzle is arranged on the spouting mechanical hand; a multi-freedom three-dimensional scanner group which is connected to a measuring control center is arranged on the spouting bridge; and the rotary device, the spouting mechanical hand and the spouting nozzle are connected to the measuring control center. The spouting support method for the intelligent spouting system disclosed by the invention comprises three-dimensional scanning, automatic first-time spouting, scanning detecting, scanned result judging and automatic fine-spouting correcting. The intelligent spouting system replaces a spouting system operator which is absolutely necessaryin the prior art, effectively improves funnel spouting support efficiency, sufficiently guarantees spouting support quality, and effectively reduces an occurrence rate of construction accidents suchas rock burst and water burst.

Description

technical field [0001] The invention relates to the technical field of spraying of full-section tunnel boring machines, in particular to an intelligent spraying system and a spraying support method thereof. Background technique [0002] The operation of the traditional TBM mixed spraying system requires high comprehensive quality of workers, long operator training period, high dependence on operators at the construction site, and harsh environment in the TBM mixed spraying operation area. Operators of the spraying system can only be proficient after practicing for at least three years Control the operating system, but the operating environment of the spraying process is harsh, and various factors cause a shortage of skilled operators, and the spraying support effect is greatly affected by the level of the operator. Therefore, there has been a shortage of experienced and skilled operators on site. Moreover, the quality of mixed spraying is greatly affected by human factors, ...
