Description

Technical Field

[0001] The utility model belongs to the technical field of engineering monitoring, and in particular relates to a device for solving the problem of pipe jamming in acoustic detection pipes. Background Art

[0002] The acoustic transmission method can be used to test the integrity of cast-in-place concrete piles with a diameter of 0.6m or greater, determining the location, extent, and severity of pile defects. The acoustic transmission method presupposes that a certain number of acoustic detection tubes are embedded in the concrete piles and that the transducer can be raised and lowered normally throughout the entire range of the acoustic detection tubes. However, in actual construction, the acoustic detection tubes often become stuck, causing significant difficulties in testing.

[0003] Currently, the buried depth of acoustic detection pipes is typically 30m to 60m. These pipes need to be tied together during the construction of the reinforcement cage, and multiple pipes need to be spliced ​​together, which can easily cause gaps. If the reinforcement cage is too long and limited by transportation and site constraints, it is often divided into two or three sections. These sections are spliced ​​at the openings during the cage installation process, and the acoustic detection pipes also need to be connected, which can easily cause gaps at the joints. Pile foundations often over-concrete during pouring, and then the piles are broken later. During the pile head treatment, concrete fragments or other soil can fall into the acoustic detection pipes, causing them to become stuck.

[0004] Patent document CN 110270563 A discloses a method for clearing blocked acoustic detection pipes in cast-in-place piles. However, the drilling equipment is bulky, inflexible, and expensive, and is time-consuming and labor-intensive to transport and use. Furthermore, the method is inefficient in handling stuck acoustic detection pipes. Utility Model Content

[0014] In the above technical solution, the power supply and control cables are 50-80m long and are marked with scales.

[0018] The advantages and beneficial effects of the utility model are:

[0019] When a pipe gets stuck in the acoustic detection pipe, the operator gradually releases the power and control cables, slowly lowering the electromagnetic suction cup, screw slider mechanism, and crushing device to the pipe-stuck position (when the power and control cables are no longer under tension, the electromagnetic suction cup, screw slider mechanism, and crushing device have reached the pipe-stuck position). The electromagnetic suction cup is then activated, securing the screw slider mechanism to the inner wall of the acoustic detection pipe. The screw slider mechanism and crushing device are then activated, causing the drill bit to rotate and move downward, thereby crushing the blockage in the acoustic detection pipe. When finished, the cable is pulled up to retract the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with specific embodiments.

[0028] A device to solve the problem of acoustic detection pipe stuck, see attached Figure 1 , including a wire drum 1, a power supply and control cable 2, a pulley mechanism 3, an electromagnetic suction cup 4, a screw slider mechanism 5 and a crushing device 6.

[0029] The pulley mechanism 3 is used to be installed on the top of the acoustic detection tube 7. Figure 2The pulley mechanism 3 includes a pulley base 9 and a fixed pulley 8 mounted on the pulley base 9. The pulley base 9 includes a circular top plate 92, a fixed pulley mounting frame 91, and a base 93. The fixed pulley mounting frame 91 is fixed to the circular top plate 92, and the fixed pulley 8 is mounted on the fixed pulley mounting frame 91. The diameter of the circular top plate 92 is slightly larger than the diameter of the acoustic detection tube 7. The base 93 is fixedly connected to the bottom surface of the circular top plate 92. The base 93 is preferably an inverted conical structure, so that the base 93 can be easily inserted into the top port of the acoustic detection tube 7 and the circular top plate 92 can be positioned above the top port of the acoustic detection tube 7. Furthermore, wire holes are provided on the circular top plate 92 and the base 93 for the power and control cables 2 to pass through.

[0030] The electromagnetic suction cup 4 is installed on the back of the screw slider mechanism 5, and the screw slider mechanism 5 can be fixedly sucked onto the inner wall of the acoustic detection tube 7 through the electromagnetic suction cup 4.

[0031] The crushing device 6 is fixedly mounted on the slider of the screw slider mechanism 5 , and the screw slider mechanism 5 can drive the crushing device 6 to move up and down inside the acoustic detection tube 7 to crush the stuck objects in the acoustic detection tube 7 .

[0032] The power supply and control cable 2 is preferably 70m long, with scales marked on it every 0.5m (the depth of the clamped pipe can be known during use), and the power supply and control cable 2 is collected in the cable drum 1; when in use, the power supply and control cable 2 can be dragged out of the cable drum 1, and the power supply and control cable 2 is passed through the pulley mechanism 3 arranged at the top of the acoustic detection tube 7 and connected to the electromagnetic suction cup 4, the screw slider mechanism 5 and the crushing device 6.

[0033] Furthermore, when the electromagnetic suction cup 4 is energized, magnetic force is generated, and when the electromagnetic force is disconnected, the magnetic force disappears. This phenomenon can be used to control the fixation and separation of the screw slider mechanism 5 and the acoustic detection tube 7, thereby adjusting the working position of the screw slider mechanism 5 and the crushing device 6.

[0034] For further information, see the attached Figure 3The screw-slider mechanism 5 includes a drive motor 15, a slider 16, a slide rod 17, a limit block 18, a mounting seat 19, and a screw rod 20. The screw rod 20 is rotatably mounted on the mounting seat 19 through a bearing assembly. One end of the screw rod 20 is connected to the output shaft of the drive motor 15. The drive motor 15 is fixed to the end of the mounting seat 19. The slide rod 17 is fixedly mounted on the mounting seat 19, and the slide rod 17 and the screw rod 20 are parallel to each other. The slider 16 is slidably mounted on the slide rod 17, and the slider 16 is threadedly mounted with the screw rod 20. The drive motor 15 drives the screw rod 20 to rotate, and then the screw rod 20 drives the slider 16 to move linearly along the slide rod 17. The limit block 18 is set at the end of the slide rod 17 to limit the movement limit position of the slider 16. The electromagnetic suction cup 4 is mounted on the mounting seat 19. Preferably, there are two electromagnetic suction cups 4, which are arranged on both sides of the mounting seat 19.

[0035] For further information, see the attached Figure 4 The crushing device 6 includes an electric motor 21, a gearbox 22, a torque adjustment mechanism 23, a chuck 24 and a drill bit 25 connected in sequence. The drill bit 25 is detachably mounted on the chuck 24, which is easy to remove and install. Different drill bit types can be conveniently selected to adapt to the situation of soil or concrete pipe jams. For example, for the situation of concrete pipe jams, it is suitable to select Figure 5 The drill bit 25a with a smaller working diameter is suitable for the case of soil stuck pipe. Figure 6 The drill bit 25b is shown with a larger sized helical rim.

[0036] Furthermore, a controller and a power supply are provided on the side of the rotating wire drum 1, and the controller and the power supply are connected to the power supply and the control cable 2, and can control the electromagnetic suction cup 4, the screw slider mechanism 5 and the crushing device 6.

[0037] The method for using the device of the utility model to solve the problem of acoustic detection pipe stuck pipe is as follows:

[0038] Step 1: Use a steel bar to insert the sonic detection tube 7 to determine whether the sonic detection tube 7 is stuck (i.e., determine whether there is a blockage in the sonic detection tube 7). If the tube is stuck, use the device of the present invention to solve the problem of sonic detection tube sticking.

[0039] Step 2: Place the electromagnetic suction cup 4, the screw slider mechanism 5 and the crushing device 6 as a whole into the acoustic detection tube 7, and then install the pulley mechanism 3 on the top of the acoustic detection tube 7, so that the power and control cable 2 passes through the pulley 8; then slowly rotate the wire drum 1, gradually release the power and control cable 2, so that the electromagnetic suction cup 4, the screw slider mechanism 5 and the crushing device 6 are slowly lowered to the tube-locking position as a whole (when the power and control cable 2 are not subject to tension, it indicates that the electromagnetic suction cup 4, the screw slider mechanism 5 and the crushing device 6 have reached the tube-locking position as a whole).

[0040] Step 3: Turn on the electromagnetic chuck 4 to fix the screw slider mechanism 5 on the inner wall of the acoustic detection tube 7, and pull the power and control cable 2 to determine whether the screw slider mechanism 5 is fixed on the inner wall of the acoustic detection tube.

[0041] Step 4: Open the screw slider mechanism 5 and the crushing device 6, so that the drill bit 25 rotates and moves downward to crush the blockage in the acoustic detection tube 7.

[0042] Step 5: Turn off the electromagnetic suction cup 4, the screw slider mechanism 5 and the crushing device 6, rotate the wire drum 1, retract the power and control cable 2, lift the electromagnetic suction cup 4, the screw slider mechanism 5 and the crushing device 6 as a whole to the top of the acoustic testing tube 7, and then take out the pulley mechanism 3 and the electromagnetic suction cup 4, the screw slider mechanism 5 and the crushing device 6.

[0043] For ease of explanation, spatial relative terms such as "upper", "lower", "left", and "right" are used in the embodiments to illustrate the relationship between one element or feature shown in the figures and another element or feature. It should be understood that, in addition to the orientation shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figure is inverted, the element described as being "under" other elements or features will be positioned "above" other elements or features. Therefore, the exemplary term "under" can include both upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used here can be interpreted accordingly.

[0044] Moreover, relational terms such as “first” and “second” are merely used to distinguish one component from another having the same name, but do not necessarily require or imply any actual relationship or order between these components.

[0045] The above is an exemplary description of the present invention. It should be noted that, without departing from the core of the present invention, any simple deformation, modification or other equivalent replacement that can be made by other technical personnel in this field without expending creative labor falls within the scope of protection of the present invention.
