Detailed Description of the Invention

[0022] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0023] According to the transducer mounting bracket of the embodiment of the present invention, the transducer mounting bracket comprises a base 1, an adjustment bracket, a limiting mechanism and a driving mechanism, the adjustment bracket comprises a first bracket 2 and a second bracket 3, the first bracket 2 is pivotally connected to the base 1 through a first adjustment shaft 4, the second bracket 3 is pivotally connected to the first bracket 2 through a second adjustment shaft 5, the driving mechanism is arranged on the first bracket 2 and is transmission-connected to the second adjustment shaft 5 to drive the second bracket 3 to rotate relative to the first bracket 2, the second bracket 3 has a receiving cavity 6 for receiving the transducer 15, and the limiting mechanism is arranged on the second bracket 3 to limit the transducer 15 from being separated from the receiving cavity 6. The base 1 is used to be fixed to the side wall of the lane to achieve the fixing of the transducer mounting bracket as a whole, and a plurality of mounting holes are arranged on the base 1, and bolts passing through the mounting holes can firmly fix the base 1 and the side wall of the lane at the target position. A portion of the first adjusting shaft 4 penetrates into the base 1 and is rotatably connected to the base 1, the first bracket 2 is connected to the first adjusting shaft 4, the first bracket 2 rotates with the first adjusting shaft 4 and then rotates relative to the side wall of the tunnel, the second adjusting shaft 5 penetrates into the first bracket 2 and can rotate relative to the first bracket 2, the second bracket 3 is fixedly connected to the second adjusting shaft 5, with the rotation of the second adjusting shaft 5, the second bracket 3 rotates relative to the first bracket 2, the first adjusting shaft 4 and the second adjusting shaft 5 form rotational freedom in two directions, the accommodating cavity 6 of the second bracket 3 accommodates the transducer 15, so that the transducer 15 can rotate with the second bracket 3 to change the position and angle of the transducer 15, thereby realizing flexible adjustment of the position of the transducer 15, and the limiting mechanism is arranged on the second bracket 3 to prevent the transducer 15 from escaping from the accommodating cavity 6 and causing damage to the transducer 15.

[0024] In some embodiments, the first adjustment shaft 4 drives the first bracket 2 to rotate on a plane parallel to the lane wall, and the second adjustment shaft 5 drives the second bracket 3 to rotate on a plane perpendicular to the lane wall.

[0025] Specifically, by rotating the first adjustment axis 4 in a plane parallel to the tunnel wall, the transducer 15 can conduct a comprehensive detection of the tunnel surroundings, obtain more extensive geological information and tunnel structure conditions, and help to timely discover safety hazards at different locations of the tunnel wall, such as potential cracks, broken zones, etc.

[0026] The rotation of the second adjustment shaft 5 perpendicular to the plane of the tunnel wall allows the transducer 15 to detect different height positions at the top and bottom of the tunnel. It can detect the stability of the tunnel roof, the bulging of the bottom plate, etc., providing more comprehensive protection for the safe production of the tunnel.

[0027] The first bracket 2 can be a hollow frame to reduce the weight of the overall mounting bracket and to facilitate the electrical connection of the transducer 15. The first adjustment axis 4 and the second adjustment axis 5 can be set with scales, so that when adjusting the angle of the transducer 15, the adjustment amplitude can be controlled more accurately.

[0028] Optionally, an anti-slip texture or anti-slip coating may be provided on the adjustment shaft to increase the friction during adjustment and avoid accidental slipping during the adjustment process.

[0029] Optionally, arranging angle sensors on the first bracket 2 and the second bracket 3 can more accurately obtain the position and angle of the transducer 15, and can intuitively understand the position and direction of the transducer 15, so as to facilitate adjustment according to actual conditions.

[0030] In some embodiments, the limiting mechanism includes a positioning card 7 and a clearance plate 8, the positioning card 7 is arranged on the inner wall of the accommodating cavity 6 away from the first bracket 2, and the clearance plate 8 is arranged on the inner wall of the accommodating cavity 6 on the side adjacent to the first bracket 2 and is connected to the inner wall of the accommodating cavity 6 through a first elastic member so that the clearance plate 8 can be displaced relative to the inner wall of the accommodating cavity 6 to clamp the transducer 15.

[0031] Specifically, the positioning card 7 and the clearance plate 8 are arranged on the inner walls of the accommodating cavity 6 on both sides. After the transducer 15 is pushed into the accommodating cavity 6, the clearance plate 8 squeezes the transducer 15 under the push of the first elastic member to fix the transducer 15. The end of the transducer 15 is blocked by the positioning card 7 and cannot be separated from the accommodating cavity 6. When the transducer 15 needs to be removed, the clearance plate 8 is pressed, the elastic member is compressed, the clearance plate 8 and the transducer 15 are separated from the positioning card 7, and the transducer 15 is separated from the positioning card 7. At this time, the transducer 15 can be removed, so that the replacement of the transducer 15 is convenient and quick.

[0032] Optionally, a plurality of positioning cards 7 may be arranged on the inner wall of the accommodating cavity 6 on the side opposite to the clearance plate 8 , and the plurality of positioning cards 7 may be evenly distributed.

[0033] The first elastic member can be a spring or an elastic rubber block. The spring has good elasticity and scalability and can provide a stable clamping force. In order to avoid fatigue deformation of the spring during long-term use, a high-strength, corrosion-resistant spring material can be selected, and the spring can be pre-compressed to ensure its elastic performance during use. The elastic rubber block has better buffering performance and sealing, which can reduce the impact of external dust, moisture, etc. on the transducer 15.

[0034] Optionally, the surface of the clearance plate 8 may be provided with anti-skid patterns such as sawtooth patterns, wavy patterns, or an anti-skid coating such as a rubber layer to increase friction, further enhance the clamping force on the transducer 15, and prevent the transducer 15 from sliding during use.

[0035] It is understandable that the displacement stroke of the clearance plate 8 in the accommodating cavity 6 should be able to adapt to the size change of the transducer 15 within a certain range, while ensuring that a certain clamping force can still be provided at the maximum displacement. Optionally, one end of the clearance plate 8 is rotatably connected to the inside of the accommodating cavity 6, and the other end of the clearance plate 8 is located at the opening of the accommodating cavity 6, and the first elastic member is also arranged at the opening. Under the push of the first elastic member, only one end of the clearance plate 8 rotates relative to the accommodating cavity 6.

[0036] In some embodiments, the limiting mechanism also includes a limiting card 9 and a clamping strip. The limiting card 9 is arranged on the side wall of the accommodating cavity 6 adjacent to the positioning card 7 and the clearance plate 8. The clamping strip is arranged on the outer wall of the transducer 15. The clamping strip is provided with clamping teeth for clamping with the limiting card 9. The clamping strip moves with the transducer 15 relative to the limiting card 9 to complete the limiting and disengagement.

[0037] Specifically, the end of the limit card 9 can be a wedge with a certain inclination angle. When the teeth on the card strip contact the limit card 9, the wedge structure can be smoothly inserted between the teeth on the card strip. At the same time, in the engaged state, the wedge surface can increase the stability of the engagement and prevent the teeth from accidentally detaching. The engagement between the limit card 9 and the card strip provides additional limiting protection for the transducer 15. Combined with the clamping effect of the positioning card 7 and the clearance plate 8, the transducer 15 is fixed from multiple directions, which greatly improves the stability of the transducer 15 in the accommodating cavity 6. When the device is subjected to large vibration, impact or external force, the engagement between the teeth and the limit card 9 can effectively prevent the transducer 15 from displacement or shaking, ensuring that the transducer 15 is always in the correct working position.

[0038] The shape of the latching teeth on the card strip can be a trapezoid or a triangle. The latching teeth abut against the wedge-shaped structure of the limit card 9 through their own inclined surfaces to complete the locking of the card strip and the limit card 9. The length of the card strip is related to the length of the transducer 15, and the length of the card strip can be less than or equal to the length of the transducer 15.

[0039] In some embodiments, the plurality of latch teeth are distributed along the length direction of the latch strip, and the width of the latch strip is greater than the width of the limiting clip 9 so that the latch teeth can be disengaged from the limiting clip 9 .

[0040] Specifically, the width of the card strip can be 2 to 5 mm greater than the width of the limit card 9. If the width difference between the card strip and the limit card 9 is too small, it will be unfavorable for the card teeth to be separated from the limit card 9, while if the width difference is too large, the clamping process may be unstable. Controlling the width difference to 2 to 5 mm can ensure that the card teeth are smoothly separated and the stability during clamping can be ensured. In order to make the card teeth more smoothly separated from the limit card 9, the edges of the card strip and the limit card 9 can be chamfered or rounded. The design of multiple card teeth distributed along the length direction of the card strip allows the transducer 15 to select a suitable clamping position according to actual conditions during installation. Different clamping positions can adapt to the installation requirements of the transducer 15 under different working conditions, thereby improving the flexibility of installation. The characteristic that the width of the card strip is greater than the width of the limit card 9 provides sufficient space for the card teeth to be separated from the limit card 9. When the transducer 15 needs to be disassembled, the operator only needs to push the transducer 15 slightly, and the card teeth can be smoothly separated from the restriction of the limit card 9, which greatly simplifies the disassembly process and saves time and labor costs. It can be understood that the limiting direction of the limiting card 9 is different from the moving direction of the transducer 15 .

[0041] Optionally, a guide groove is provided on the side wall of the accommodating cavity 6, and the card strip moves along the guide groove to ensure that the card strip maintains linear motion during the movement, thereby improving the clamping accuracy between the clamping teeth and the limit card 9. The width of the guide groove is greater than the sum of the width of the card strip and the width of the limit card 9, so that the card strip can move relative to the limit card 9 in the guide groove.

[0042] In some embodiments, the two limiting cards 9 are symmetrical with respect to the positioning card 7 and the distances between the limiting cards 9 and the card strip are the same.

[0043] Specifically, the shape of the limit card 9 can be L-shaped, the L-shaped short side of the limit card 9 is engaged with the edge of the transducer 15, and the L-shaped long side of the limit card 9 is connected to the inner wall of the accommodating cavity 6. The two limit cards 9 are symmetrical about the positioning card 7 and can evenly disperse the force, so that the transducer 15 is more evenly stressed. When vibrated or collided, the symmetrical limit cards 9 can jointly withstand the impact force to ensure that the engagement state between the limit card 9 and the transducer 15 remains unchanged, thereby ensuring the normal operation of related components. The same distance between the limit card 9 and the card strip also facilitates the adjustment of the engagement state between the card strip and the limit card 9.

[0044] In some embodiments, the driving mechanism includes a servo motor 10 and a synchronous belt 11 . The servo motor 10 is arranged on the first bracket 2 , and the servo motor 10 is transmission-connected to the second adjusting shaft 5 via the synchronous belt 11 .

[0045] Specifically, the servo motor 10 can achieve high-precision speed and position control. The servo motor 10 drives the synchronous belt 11, which can drive the second adjustment shaft 5 to rotate, achieving high-precision rotational adjustment. The high transmission efficiency of the synchronous belt 11 can adjust the rotation of the second adjustment shaft 5, and the synchronous belt 11 is convenient for maintenance and replacement.

[0046] In some embodiments, a positioning mechanism is further included. The positioning mechanism includes a positioning gear disk 12 and a positioning member. The positioning gear disk 12 is arranged on the second adjustment shaft 5, and the positioning member is arranged on the first bracket 2. The positioning member is displaced relative to the positioning gear disk 12 to lock and release the positioning gear disk 12.

[0047] Specifically, the positioning gear disk 12 is fixedly connected to the second adjustment shaft 5. When a part of the positioning member is inserted between the teeth of the positioning gear disk 12, it can prevent the positioning gear disk 12 from rotating, and further prevent the second adjustment shaft 5 from rotating, thereby achieving the locking and positioning of the second bracket 3.

[0048] Optionally, the positioning member has fixed teeth that mesh with the positioning gear disk 12. An electric push rod or a cylinder can be used to drive the positioning member to achieve the displacement of the positioning member relative to the positioning gear disk 12, thereby completing the locking and loosening of the positioning member to the positioning gear disk 12, and enabling quick adjustment and positioning according to different working requirements.

[0049] In some embodiments, the positioning member includes a positioning shell 13 and a positioning rod 14. The positioning shell 13 has a sliding cavity, and at least part of the positioning rod 14 slides in the sliding cavity. The two ends of the second elastic member are respectively connected to the positioning shell 13 and the positioning rod 14. The second elastic member is arranged in the sliding cavity to push the positioning rod 14 in the direction of the positioning gear disk 12.

[0050] Specifically, the positioning shell 13 can be in the shape of a cylinder, a cuboid, etc. One end of the sliding cavity of the positioning shell 13 is open for the positioning rod 14 to enter and exit. The positioning shell 13 can be fixed to the first bracket 2 by means of bolt connection, welding, etc. The end of the positioning rod 14 facing the positioning gear disk 12 can be designed as a triangular pyramid or serrated shape, which can more easily enter between the teeth of the positioning gear disk 12 when contacting the positioning gear disk 12, achieving quick positioning.

[0051] Optionally, the end of the positioning rod 14 entering the sliding cavity can be adapted according to the cross-sectional shape of the sliding cavity. The end of the positioning rod 14 is arranged in the shape of a circular sheet or a rectangular sheet, etc. to closely fit the sliding cavity, which can prevent the positioning rod 14 from tilting and sliding and affecting the positioning.

[0052] Optionally, a buffer pad, such as a rubber pad, is arranged at one end of the positioning rod 14 facing the positioning gear disk 12 to reduce the impact force generated when the positioning rod 14 collides with the positioning gear disk 12, reduce noise, and at the same time protect the tooth profiles of the positioning gear disk 12 and the positioning rod 14. The second elastic member pushes the positioning rod 14 to move towards the positioning gear disk 12, enabling automatic positioning.

[0053] When the second adjustment shaft 5 rotates to a suitable position, the positioning rod 14 automatically inserts into the tooth groove of the positioning gear disk 12 under the action of the elastic force, completing the positioning operation without manual intervention, improving the efficiency and accuracy of positioning. The second elastic member has a buffering effect. At the moment when the positioning rod 14 contacts the positioning gear disk 12, the elastic member can absorb a part of the impact force, reduce the wear and damage between the positioning rod 14 and the positioning gear disk 12, and extend the service life of the positioning mechanism. At the same time, the buffering effect can also reduce the noise generated during the positioning process and improve the working environment.

The fixed bracket is connected to the side wall of the roadway, and the movable bracket 100 is a transducer mounting bracket, and the movable bracket 100 is arranged on the side wall of the roadway on the opposite side of the fixed bracket.

[0055] The mine ultrasonic transducer 15 auxiliary alignment device relatively arranges a signal transmitter mounting bracket and a signal receiver mounting bracket on both side walls of the roadway. The signal transmitter mounting bracket can be flexibly adjusted corresponding to the signal receiver mounting bracket, enabling the signal transmitter and the receiver to be flexibly aligned and adjusted, ensuring the stable operation of the ultrasonic transducer 15. Through the design of the fixed bracket and the movable bracket 100, the installation process of the transducer 15 is modularized and standardized. The fixed bracket can be pre-installed on the side wall of the roadway in advance, and the movable bracket 100 can pre-install the transducer 15 on the ground and then be integrally installed on the other side of the roadway. This method reduces the installation time at the underground site, improves the installation efficiency, and reduces the labor intensity of workers. The adjustable structure of the movable bracket 100 enables the transducer 15 to be conveniently adjusted in position and angle, ensuring that the ultrasonic transducer 15 can accurately transmit and receive signals, improving the accuracy and reliability of the measurement.
