Description

Technical Field

[0001] The utility model relates to the technical field of hole-forming and groove-forming quality detectors, in particular to an ultrasonic hole-forming and groove-forming quality detector. Background Technique

[0002] An ultrasonic hole-forming and groove-forming quality detector is an instrument based on the principle of underwater ultrasonic ranging, which is used to measure the groove width, groove depth, verticality, etc. of geotechnical engineering, and then evaluate the forming situation of the groove body.

[0003] After searching, Chinese Patent CN213396982U discloses an ultrasonic hole-forming and groove-forming quality detector. By setting a rotating motor, the rotating shaft can be driven to rotate inside the bearing, and at the same time, the brush can be driven to rotate through the connecting rod. Then, the surface of the detector can be cleaned by the brush to prevent excessive impurities on the surface of the detector from affecting the next use. When using the device, the observation window can be used to observe the internal working and cleaning conditions of the chamber. By setting the clamping wheel and the damper, when the steel wire rope is released or wound up, the damper can clamp the surface of the steel wire rope through the clamping wheel, and at the same time, the sundries on the surface of the steel wire rope can be reduced. It can also provide a stable clamping force when the detector moves upward to prevent the detector from shaking left and right. By setting the driving motor, the steel wire rope can be wound up and released through the storage disc, so as to facilitate controlling the descending depth of the detector. By setting the universal wheels, the box body can be moved to the designated position, and at the same time, it is also convenient to move and store the device when it is not in use. It can be seen that this patent realizes the cleaning of the surface of the detector, the clamping of the surface of the steel wire rope, the prevention of the detector from shaking left and right, and the facilitation of pulling the detector to move up and down. However, when the ultrasonic sensor is lifted and placed above, the ultrasonic sensor is still connected to the steel wire rope, and the steel wire rope is still under stress. Long-term hanging will increase the fatigue strength of the steel wire rope and affect the service life of the steel wire rope. Therefore, a corresponding structure needs to be set to hang the ultrasonic sensor, so an ultrasonic hole-forming and groove-forming quality detector is proposed. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides an ultrasonic hole-forming and groove-forming quality detector, which has the advantage of being convenient for hanging.

[0007] Furthermore, the outer surface of the output shaft of the first servo motor is fixedly connected to the first roller, and the outer surface of the output shaft of the second servo motor is fixedly connected to the take-up drum.

[0008] Furthermore, the hanging arm is obliquely arranged on the top wall of the moving frame, the guide arm is in an arc shape, and control cabinets are installed on both sides of the inner top wall of the moving frame.

[0009] Furthermore, a threaded rod is rotatably connected between the front side wall and the rear side wall of the movable frame and located above the wire take-up drum. Sprockets are fixedly installed on the outer surfaces of the wire take-up drum, the first roller, the second roller and the threaded rod.

[0013] The ultrasonic hole and groove forming quality detector is provided with a suspension assembly. After the suspension assembly is used, as the hanging rope pulls the hanging rod, the ultrasonic sensor is lifted accordingly. The hanging rod first touches the guiding arm and moves along the outer surface of the guiding arm to the upper part of the guiding arm. As the second roller releases the hanging rope, the hanging rod slides along the outer surface of the inclined hanging arm into the clamping groove and is inserted into the hanging arm.

Detailed Embodiment

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-3, An ultrasonic hole-forming and groove-forming quality detector, which includes a mobile frame 1 and an ultrasonic sensor 2. A cable 19 is connected to the ultrasonic sensor 2. A wire reel 3 is rotatably connected between the opposite sides of the front side wall and the rear side wall of the mobile frame 1 for winding the cable 19. A first roller 4 is rotatably connected between the opposite sides of the front side wall and the rear side wall of the mobile frame 1 and is located outside the wire reel 3. The first roller 4 can rotate on the mobile frame 1. A second roller 5 is rotatably connected between the opposite sides of the front side wall and the rear side wall of the mobile frame 1 and is located outside the first roller 4. The second roller 5 can rotate on the mobile frame 1 to wind or release the hanging rope 18, driving the lifting or lowering of the ultrasonic sensor 2.

[0021] Among them, two mounting brackets 6 are fixedly installed on the rear side wall of the mobile frame 1. A first servo motor 7 is fixedly installed on one mounting bracket 6. The outer surface of the output shaft of the first servo motor 7 is fixedly connected to the first roller 4. When the first servo motor 7 is started, the first roller 4 rotates to gradually perform the work of pulling up or releasing the hanging rope 18. A second servo motor 8 is fixedly installed on the other mounting bracket 6. The outer surface of the output shaft of the second servo motor 8 is fixedly connected to the wire reel 3. When the second servo motor 8 is started, the wire reel 3 rotates to gradually perform the work of winding or releasing the cable 19. The first servo motor 7 is located inside the first roller 4, reducing the occupied space of the first servo motor 7 on the mobile frame 1. The second servo motor 8 is located inside the wire reel 3, reducing the occupied space of the second servo motor 8 on the mobile frame 1. Furthermore, the internal space of the wire reel 3 and the first roller 4 is fully utilized. Control cabinets 10 are installed on both sides of the inner top wall of the mobile frame 1.

[0022] Please refer to Figures 2-4 , A suspension assembly 9 is provided on the mobile frame 1. The suspension assembly 9 includes a hanging arm 91, a guiding arm 92, a card slot 93 and a hanging rod 94. The hanging arm 91 is fixedly installed on the top wall of the mobile frame 1. The hanging arm 91 is inclined on the top wall of the mobile frame 1. The guiding arm 92 is fixedly connected to the tail of the hanging arm 91. The hanging rod 94 is in contact with the hanging arm 91 and the guiding arm 92. The shape of the guiding arm 92 is arc-shaped. The hanging rod 94 can move along the arc-shaped guiding arm 92 to the upper part of the guiding arm 92 and then be inserted into the card slot 93 for limiting. The card slot 93 is opened on the hanging arm 91. The hanging rod 94 can move along the hanging arm 91 to the card slot 93 for hanging. The hanging rod 94 is hinged to the top of the ultrasonic sensor 2. The hanging rod 94 is inserted into the card slot 93, enabling the hanging arm 91 provided with the card slot 93 to support the hanging rod 94, facilitating the suspension of the ultrasonic sensor 2, reducing the fatigue strength caused by continuously pulling with the hanging rope 18, and prolonging the service life of the hanging rope 18.

[0023] Please refer to Figures 2-4A threaded rod 11 is rotatably connected between the front side wall and the rear side wall of the mobile frame 1 and located above the take-up drum 3. The outer surfaces of the take-up drum 3, the first roller 4, the second roller 5 and the threaded rod 11 are all fixedly installed with a sprocket 12. The outer surface of the sprocket 12 is transmission-connected with a chain 13. Under the transmission of the sprocket 12 and the chain 13, the take-up drum 3 rotates to reel or release the cable 19, and the second roller 5 rotates to reel or release the hanging rope 18, thereby driving the ultrasonic sensor 2 to rise and fall. A fixed rod 14 is fixedly installed between the front side wall and the rear side wall of the mobile frame 1. The outer surface of the threaded rod 11 is threadedly connected with a movable seat 15 slidably connected to the fixed rod 14, limiting the freedom of the rotation direction of the movable seat 15 so that the movable seat 15 can only move. The movable seat 15 pulls the cable 19 to move during the winding or releasing process, avoiding the cable 19 being entangled at only one position on the outer surface of the take-up drum 3, thereby ensuring the uniformity of the cable 19 when it is wound.

[0024] In addition, the front side wall, the rear side wall and the inner top wall of the mobile frame 1 are fixedly installed with a fixing frame 16, and the inner sides of the movable seat 15 and the fixing frame 16 are rotatably connected with guide wheels 17 for guiding the hanging rope 18 and the cable 19. The cable 19 is wound around the outer surface of the take-up drum 3, and the cable 19 also passes through the guide wheel 17. The hanging rod 94 is tied with a hanging rope 18 that passes through the guide wheel 17 and is connected to the outer surface of the second roller 5. The hanging rod 94 is used to pull or release the hanging rod 94, thereby driving the ultrasonic sensor 2 to rise and fall, so as to detect the width, verticality, collapse expansion and contraction position and inclination direction of the underground continuous wall groove.

[0025] When the present embodiment is in use, the first servo motor 7 and the second servo motor 8 are started, and the take-up drum 3, the threaded rod 11, the first roller 4 and the second roller 5 are rotated under the transmission of the sprocket 12 and the chain 13. The take-up drum 3 rotates to reel the cable 19 wound on the outer surface of the take-up drum 3, and the threaded rod 11 rotates to drive the movable seat 15 to move, so that the cable 19 is evenly wound on the outer surface of the take-up drum 3. The rotation of the second roller 5 can pull the hanging rope 18 to lift the hanging rod 94, and the ultrasonic sensor 2 is driven to rise. The hanging rod 94 touches the guide arm 92 and moves along the outer surface of the guide arm 92 to the top of the guide arm 92. With the reversal of the second roller 5, a part of the hanging rope 18 is released, and the hanging rod 94 slides into the card slot 93 along the outer surface of the inclined hanging arm 91 and plugs into the hanging arm 91, thereby completing the suspension of the ultrasonic sensor 2.

[0026] The beneficial effects of the above embodiments are:

[0027] The ultrasonic hole and groove forming quality detector is provided with a suspension assembly 9. After the suspension assembly 9 is used, as the hanging rope 18 pulls the hanging rod 94, the ultrasonic sensor 2 is lifted accordingly. The hanging rod 94 first touches the guiding arm 92 and moves along the outer surface of the guiding arm 92 to the upper part of the guiding arm 92. As the second roller 5 releases the hanging rope 18, the hanging rod 94 slides along the outer surface of the inclined hanging arm 91 into the card slot 93 and is inserted into the hanging arm 91. Since the hanging arm 91 is fixed to the moving vehicle frame 1, the ultrasonic sensor 2 can be suspended and placed, reducing the labor intensity caused by continuously using the hanging rope 18 for suspension and extending the service life of the hanging rope 18. By placing the first servo motor 7 inside the first roller 4 and the second servo motor 8 inside the wire reel 3, the situation of increased occupied space caused by installing the first servo motor 7 and the second servo motor 8 outside the moving vehicle frame 1 is reduced, which is beneficial to making full use of the internal space of the wire reel 3 and the first roller 4.

[0028] The first servo motor 7 and the second servo motor 8 mentioned in the text are both electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer for control, and the existing publicly disclosed electrical connection technology will not be elaborated in the text.
