Abstract
Description
Technical Field
[0001] This utility model relates to the field of laser detection equipment technology, and in particular to a laser detection device for the centerline of a tunneling face. Background Technology
[0002] Traditional manual inspection of the centerline laser involves the inspector observing whether the laser is simultaneously illuminating three or more cables after the shift begins. While this method might show the laser still illuminating three cables, the direction may be incorrect, and workers typically don't correct it, potentially leading to centerline accidents. Currently, the laser device at the underground tunneling face lacks any protection. During operations near the laser device, such as when installing roof anchors, accidental laser activation is possible. The centerline determines the direction of the tunneling face and is crucial for directional guidance. Therefore, improvements are needed to address these issues. Utility Model Content

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: In this utility model, the cooperation of the worm gear, worm wheel, screw and connecting cylinder facilitates the adjustment of the relative position of the laser protective cover and the laser detection frame, thereby making the laser detection position accurately adapt to the actual needs of the tunneling face; the cooperation of the first observation window and the second observation window facilitates the observation of the working status of the internal components of the laser protective cover by the workers, and the second observation window is darker than the first observation window, which can reduce the stimulation of strong light on the workers' eyesight, thereby protecting the workers' eyesight and improving the comfort and safety of the observation process in underground operations; the cooperation of the laser protective cover and the laser detection frame facilitates the formation of overall protection for the laser device, avoiding accidental contact with the laser during underground operations, thereby solving the problem of traditional underground laser devices being unprotected and prone to accidental contact, thereby reducing the risk of tunneling centerline accidents caused by accidental laser contact and ensuring that tunneling operations are carried out in the correct direction.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0014] Example: See Figures 1 to 4This utility model discloses a laser detection device for the centerline of a tunneling face, comprising a laser protective cover 1, a laser detection frame 2 on one side of the laser protective cover 1, and elongated holes 3 vertically opened on the side of the laser detection frame 2. Connecting components are installed at the four corners of the top surface of the laser protective cover 1 and the front and rear ends of the top surface of the laser detection frame 2. The laser protective cover 1 protects the internal laser source module 4, beam shaper 5, and laser optical axis calibrator 6, preventing these core components from being affected by the external environment. The laser detection frame 2 provides structural support for laser detection. The elongated holes 3 facilitate laser penetration, detection observation, or adjustment of related components. A first observation window 7 is movably hinged to one side of the front surface of the laser protective cover 1, and a second observation window 8 is provided at the front end of the first observation window 7. The upper end of the second observation window 8 is movably hinged to the laser protective cover 1. The second observation window 8 is a darker color than the first observation window 7. The first observation window 7 facilitates the observation of the working status of the laser components inside the laser protective cover 1, while also providing some protection. The second observation window 8 assists in observing the internal situation and reduces the stimulation of strong light on the eyes of the workers, protecting their vision. The laser protective cover 1 houses a laser source module 4, with a beam shaper 5 installed on one side and a laser optical axis calibrator 6 installed on the other side. The laser source module 4 provides the laser required for centerline detection of the tunneling face. The beam shaper 5 optimizes the beam shape, ensuring the stability of laser detection. The laser optical axis calibrator 6 ensures precise laser optical axis alignment, directly improving the accuracy of centerline detection of the tunneling face.
[0015] In this utility model, the connecting assembly includes a housing 9 installed at the four corners of the top surface of the laser protective cover 1 and the front and rear ends of the top surface of the laser detection frame 2. A connecting cylinder 14 is vertically provided at the upper end of the housing 9. A threaded groove is formed on the bottom surface of the connecting cylinder 14, and a connecting plate 15 is installed on the top surface of the connecting cylinder 14. The housing 9 facilitates the protection of transmission components such as the worm gear 10 and worm wheel 12 inside the connecting assembly. The connecting cylinder 14 facilitates the connection between the screw 13 and the connecting plate 15. The connecting plate 15 facilitates the fixed installation of the device, ensuring the stability of the device during operation. The housing 9 is rotatably connected to... A worm gear 10 is connected to a worm wheel 12 on one side. The worm wheel 12 is rotatably connected inside the housing 9, and one end of the worm gear 10 passes through the housing 9 and is connected to a motor 11 via a coupling. The motor 11 is mounted on the housing 9. The arrangement of the worm wheel 12 and the worm gear 10 facilitates the rotation of the screw 13 and enables the screw 13 to be locked. The arrangement of the motor 11 facilitates the synchronous control of the rotation of the worm gear 10. The top surface of the worm wheel 12 is vertically fixed to the screw 13, the upper end of which passes through the housing 9 and is threadedly connected to the connecting cylinder 14. The arrangement of the screw 13 facilitates the control of the lifting and lowering of the connecting cylinder 14.
[0016] Working Principle: In the use of this utility model, firstly, all electrical equipment is connected by wires and powered on. Then, the laser source module 4 is started to emit the laser required for centerline detection of the tunneling face. The laser beam first passes through the beam shaper 5 to optimize its shape and ensure the stability of laser detection. Then, the laser optical axis is calibrated by the laser optical axis calibrator 6 to avoid laser deviation and ensure detection accuracy. Then, the laser beam passes through a rope and through the elongated hole 3 on the side of the laser detection frame 2 to act on the tunneling face for centerline detection. Finally, the motor 11 is started to control the rotation of the worm gear 12 and worm 10, which in turn drives the top surface through the worm gear 12. The fixed screw 13 rotates, and then the screw 13 engages with the threaded groove on the bottom surface of the connecting cylinder 14, thereby driving the connecting cylinder 14 to move vertically, thereby adjusting the relative position of the laser protective cover 1 and the laser detection frame 2, so that the laser detection position is accurately adapted to the needs of the tunneling working face; when it is necessary to observe the working status of the internal laser components, the second observation window 8 is darker than the first observation window 7, which can reduce the stimulation of strong light on the eyes of the workers and protect their eyesight; when it is necessary to inspect and repair the laser module, the second observation window 8 and the first observation window 7 are opened, so that the laser module can be inspected and repaired.
[0017] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
