Description

Technical Field

[0001] This application relates to the technical field of sound wave line recycling, and in particular to an anti-tangling device for sound wave line recycling. Background Art

[0002] In the detection of pile foundation by sonic transmission method, the sound wave line is used to connect the transducer. During the detection process, the sound wave line needs to drive the transducer to be gradually lifted upwards, so that the sound wave line is temporarily loosely stacked on the ground. When detecting a long pile foundation, the length of the lowered sound wave line is relatively long. Therefore, when detecting the next pile foundation, if the sound wave line stacked on the ground is not rewound onto the winding device and directly moved into the next pile foundation, it is easy for the different sound wave lines to be entangled and knotted due to the stacking of the sound wave lines. And during the process of rewinding the sound wave line back onto the winding device, the operator needs to drag the sound wave line and sort out the position where the sound wave line is wound onto the winding device, which is rather troublesome and prone to scratching the operator's palm. Summary of the Invention

[0003] In order to improve the convenience of sound wave line recycling, this application provides an anti-tangling device for sound wave line recycling.

[0004] This application provides an anti-tangling device for sound wave line recycling, adopting the following technical solutions: An anti-tangling device for sound wave line recycling, comprising: A winding unit and an auxiliary unit; The winding unit includes a base frame, a winding shaft and side discs; the winding shaft is rotatably connected to the base frame, and there are two side discs which are respectively coaxially sleeved at both ends of the winding shaft; The auxiliary unit includes a support frame, a reciprocating lead screw, a guide wheel and a synchronizing member; the support frame is installed on the base frame; the reciprocating lead screw is rotatably connected to the support frame and is opposite to the winding shaft, and the reciprocating lead screw is parallel to the winding shaft; the guide wheel is sleeved on the reciprocating lead screw and is in threaded engagement with the thread on the reciprocating lead screw; the synchronizing member is connected to one of the side discs; Wherein, the sound wave line is wound around the guide wheel and then wound onto the winding shaft; when the side disc rotates and drives the synchronizing member to rotate together, the synchronizing member can drive the reciprocating lead screw to rotate, so that the guide wheel reciprocates along the axis of the reciprocating lead screw.

[0005] By adopting the above technical solutions, through the coordinated action of the winding unit and the auxiliary unit, the orderly recycling and anti-tangling of the sound wave line are realized. The winding shaft and the side discs cooperate to realize the winding of the sound wave line. The reciprocating lead screw, the guide wheel and the synchronizing member in the auxiliary unit enable the sound wave line to be evenly distributed along the axial direction of the winding shaft during the winding process, avoiding entanglement and knotting, and improving the recycling efficiency and convenience.

[0006] Optionally, the synchronizing member is annular and coaxially connected to the side disc. The outer periphery of the synchronizing member has a tooth segment and a smooth segment that are sequentially distributed in the circumferential direction. The tooth segment has teeth distributed in the circumferential direction of the synchronizing member, and the tooth segment protrudes from the synchronizing member relative to the smooth segment. A synchronous gear opposite to the outer periphery of the synchronizing member is coaxially sleeved and fixed on the reciprocating lead screw. When the tooth segment of the synchronizing member rotates to pass by the synchronous gear, the tooth segment meshes with the synchronous gear to drive the synchronous gear to rotate one week.

[0007] By adopting the above technical solution, through the meshing of the tooth segment of the synchronizing member and the synchronous gear, the synchronous rotation of the winding shaft and the reciprocating lead screw is realized, so that the guide wheel can reciprocate along the axis of the reciprocating lead screw when the winding shaft winds.

[0008] Optionally, a ball plunger is eccentrically arranged on one end face of the reciprocating lead screw. The support frame has an arc groove for the ball head of the ball plunger to abut against. When the tooth segment leaves the synchronous gear, the ball head of the ball plunger abuts into the arc groove.

[0009] By adopting the above technical solution, when the tooth segment leaves the synchronous gear, the ball head of the ball plunger abuts into the arc groove, realizing the automatic positioning of the reciprocating lead screw and preventing the reciprocating lead screw from continuing to rotate due to inertia or other factors.

[0010] Optionally, a connecting portion is arranged on the support frame. The connecting portion extends into the synchronizing member, and an annular groove for the connecting portion to slide is coaxially opened on the end face of the synchronizing member.

[0011] By adopting the above technical solution, through the sliding fit of the connecting portion and the synchronizing member, the stable connection between the synchronizing member and the support frame is realized, and at the same time, the synchronizing member is allowed to rotate relative to the support frame, improving the overall stability and reliability of the device.

[0012] Optionally, the inner diameter of the synchronizing member is larger than the outer diameter of the side disc. A plurality of abutting columns are arranged at intervals along the circumferential direction of the inner periphery of the synchronizing member. The abutting columns are threadedly moved on the synchronizing member in the radial direction of the synchronizing member. One end of the abutting column away from the synchronizing member abuts against the outer periphery of the side disc, and at least one connecting groove for the abutting column to insert is provided on the outer periphery of the side disc.

[0013] By adopting the above technical solution, through the abutting of the abutting column against the outer periphery of the side disc and the cooperation of the connecting groove, the detachable connection between the synchronizing member and the side disc is realized, facilitating the assembly, maintenance and replacement of components of the device.

[0014] Optionally, a plurality of centering pieces are distributed at intervals along the inner shaft of the synchronizing piece, and one end of each centering piece is rotatably connected to the inner circumference of the synchronizing piece; a driving ring is rotatably connected to the synchronizing piece coaxially, and the driving ring is engaged with the hinged ends of all the centering pieces simultaneously through a toothed structure.

[0015] By adopting the above technical solution, by rotating the driving ring to drive all the centering pieces to abut against the outer circumference of the side disc, the automatic centering between the synchronizing piece and the side disc is achieved, and the convenience of confirming the relative position with the side disc during the installation of the synchronizing piece is improved.

[0016] Optionally, the support frame has a limiting portion opposite to the reciprocating lead screw, the guide wheel has a moving portion for clamping the limiting portion, and the moving portion can slide axially relative to the limiting portion along a direction parallel to the axis of the winding shaft to limit the rotation of the guide wheel relative to the support frame.

[0017] By adopting the above technical solution, through the cooperation of the limiting portion and the moving portion, the rotation of the guide wheel relative to the support frame is restricted, so that the guide wheel can only slide axially along the reciprocating lead screw, further enhancing the uniformity and orderliness of the recovery of the acoustic detection line.

[0018] Optionally, a flexible water-absorbing strip abuts against one side of the limiting portion facing the reciprocating lead screw, and the flexible water-absorbing strip is arranged along a direction parallel to the acoustic detection line passing through the guide wheel to contact and absorb water.

[0019] By adopting the above technical solution, the flexible water-absorbing strip can absorb the moisture on the acoustic detection line passing through the guide wheel, improve the dryness of the acoustic detection line, and extend the service life of the acoustic detection line.

[0020] Optionally, an extension handle is rotatably connected to the support frame, one end of the flexible water-absorbing strip is connected to the extension handle, and the other end of the flexible water-absorbing strip is connected to the support frame; The side disc is eccentrically provided with a handle, one end of the extension handle extends to face the side disc, and the extension handle is located in the moving path of the handle when the side disc rotates, so that the handle pushes the extension handle to rotate when passing through the extension handle.

[0021] By adopting the above technical solution, through the cooperation of the extension handle and the handle, the automatic pushing of the extension handle to rotate when the side disc rotates is achieved, so as to drive the flexible water-absorbing strip to twist and squeeze water, thereby maintaining the water absorption effect of the flexible water-absorbing strip.

[0022] Optionally, the connecting frame is detachably connected to the base frame.

[0023] By adopting the above technical solution, through the detachable connection between the connecting frame and the base frame, the overall detachability of the device is achieved, which is convenient for the transportation, assembly and maintenance of the device, and improves the flexibility and practicality of the device.

[0024] In summary, the present application includes at least one of the following beneficial effects: 1. Through the reciprocating movement of the guide wheel on the reciprocating lead screw, it is assisted that the acoustic detection line can be evenly and orderly wound around the winding shaft during the recovery process, reducing the manual dragging of the acoustic detection line and improving the convenience of recovering the acoustic detection line; 2. By disassembling and assembling the auxiliary unit between the connecting frame and the base frame, and between the abutting column and the side plate, the auxiliary unit can be detachably connected to the winding unit, so as to improve the flexibility of the device.

[0027] The following will be further described in detail with reference to the attached Figure 1 to the attached Figure 7 drawings of the present application.

[0028] Embodiment of the present application discloses an anti-tangling device for recovering an acoustic detection line. Refer to Figure 1, The sound wave detection line recovery anti-tangling device includes a winding unit and an auxiliary unit. The winding unit is used for winding the sound wave detection line, and the auxiliary unit is installed on the winding unit and is used to assist the sound wave detection line to be evenly distributed on the winding unit during wire winding.

[0029] Referring to Figure 1 and Figure 2 , among them, the winding unit includes a base frame 1, a winding shaft 2 and side discs 3. The base frame 1 has a counterweight as an installation base and is placed on the ground during use. The winding shaft 2 is rotatably connected to the base frame 1 and extends horizontally, and is used for winding the sound wave detection line. The side discs 3 are disc-shaped and there are two of them. The two side discs 3 are respectively coaxially fixed at the two ends of the winding shaft 2 away from each other, so as to limit the winding range of the sound wave detection line between the two side discs 3. The part of the side disc 3 close to the outer circumference is also evenly spaced with through holes along its circumferential direction, so as to reduce the weight of the side disc 3 and facilitate the operator to carry it.

[0030] It should be noted that only one end of the winding shaft 2 is rotatably connected to the base frame 1, and a handle 22 is fixed on the side disc 3 opposite to the other end of the winding shaft 2. The length direction of the handle 22 is parallel to the axial direction of the winding shaft 2, and the handle 22 is eccentric relative to the winding shaft 2. By holding the handle 22 to drive the side disc 3 to rotate, the winding shaft 2 can be driven to rotate together, so as to wind the sound wave detection line.

[0031] Referring to Figure 1 and Figure 3 , the auxiliary unit includes a support frame 4, a reciprocating lead screw 5, a guide wheel 6 and a synchronizing member 7. The support frame 4 is detachably installed on the base frame 1 by bolts. The support frame 4 extends to be opposite to the outer circumferences of both the side disc 3 and the winding shaft 2 at the same time, and the part of the support frame 4 opposite to the outer circumference of the side disc 3 is located obliquely above the side disc 3.

[0032] The reciprocating lead screw 5 is rotatably connected to the support frame 4 by rotating and embedding the rotating shafts fixed coaxially at both ends of itself into the support frame 4. The reciprocating lead screw 5 is provided with thread grooves with opposite and staggered thread directions, and the reciprocating lead screw 5 is opposite to the outer circumferences of the side disc 3 and the winding shaft 2. The axis of the reciprocating lead screw 5 is parallel to the axis of the winding shaft 2. The guide wheel 6 is coaxially sleeved on the reciprocating lead screw 5. The guide wheel 6 is formed with a guide groove 23 for the sound wave detection line to abut along the circumferential direction, and a convex block moving in the thread groove of the reciprocating lead screw 5 is fixed on the inner circumference of the guide wheel 6. At the same time, the guide wheel 6 has a moving part 19 cooperating with the support frame 4 to limit the rotation of the guide wheel 6 relative to the support frame 4. When the reciprocating lead screw 5 rotates in a single direction in a cycle, the guide wheel 6 can move left and right along the axial direction of the reciprocating lead screw 5 under the restriction of the moving part 19 through the cooperation of the convex block and the thread groove.

[0033] Among them, the support frame 4 has a limiting portion 18 for cooperating with the moving portion 19. The limiting portion 18 is opposite to the winding shaft 2 and is in the shape of a square rod extending along the axial direction of the parallel winding shaft 2. The moving portion 19 is rod-shaped and fixed to the outer periphery of the guide wheel 6. Both ends of the guide wheel 6 in the direction of its own axis are provided with two moving portions 19. The two moving portions 19 at each end of the guide wheel 6 jointly abut against the opposite sides of the limiting portion 18 to clamp the limiting portion 18, thereby restricting the rotation of the guide wheel 6 relative to the limiting portion 18. At the same time, the acoustic detection line wound around the guide wheel 6 can be limited between the two ends of the guide wheel 6. When the guide wheel 6 rotates axially along the reciprocating screw rod 5, it drives the moving portion 19 to slide on the side surface of the limiting portion 18.

[0034] Referring to Figure 1 and Figure 4 , the synchronizing member 7 is in the shape of a circular ring and coaxially surrounds and connects to the side plate 3 with a handle 22. The synchronizing member 7 is simultaneously engaged with the reciprocating screw rod 5, so that when the side plate 3 rotates, it simultaneously drives the synchronizing member 7 to rotate, and the synchronizing member 7 drives the reciprocating screw rod 5 to rotate.

[0035] Specifically, the inner diameter of the synchronizing member 7 is larger than the outer diameter of the side plate 3. A plurality of abutting columns 14 are threadedly connected at intervals along the circumferential direction of the inner periphery of the synchronizing member 7. The abutting columns 14 move threadedly along the radial direction of the synchronizing member 7. At least one connecting groove 15 for inserting the abutting columns 14 is provided on the outer periphery of the side plate 3. In this embodiment, the number of the connecting grooves 15 is one. One of the abutting columns 14 is inserted into the connecting groove 15, and the ends of the remaining abutting columns 14 away from the inner periphery of the synchronizing member 7 all abut against the outer peripheral wall of the side plate 3, and the distances from the outer periphery of the side plate 3 to the inner periphery of the synchronizing member 7 of the respective abutting columns 14 are all the same, so that the synchronizing member 7 and the side plate 3 are concentric.

[0036] Referring to Figure 3 and Figure 4 , the outer periphery of the synchronizing member 7 has a tooth section 8 and a smooth section 9 distributed in sequence along its circumferential direction. The tooth section 8 has teeth protruding outward relative to the smooth section 9, and the teeth are evenly spaced along the circumferential direction of the synchronizing member 7. One end of the reciprocating screw rod 5 is opposite to the outer periphery of the synchronizing member 7 and is coaxially fixedly sleeved with a synchronizing gear 10. The number of teeth, tooth module, pressure angle and tooth height of the synchronizing gear 10 are the same as those of the tooth section 8. When the synchronizing member 7 rotates to the smooth section 9 facing the synchronizing gear 10, there is a distance between the synchronizing member 7 and the synchronizing gear 10 without interference with the synchronizing gear 10; when the synchronizing member 7 rotates to the tooth section 8 facing the synchronizing gear 10, the tooth section 8 meshes with the synchronizing gear 10 to drive the reciprocating screw rod 5 to rotate together. When the tooth section 8 completely passes the synchronizing gear 10, it drives the reciprocating screw rod 5 to rotate one week.

[0037] Referring to Figure 1 and Figure 5, wherein, in order to improve the matching accuracy between the tooth segment 8 and the synchronous gear 10, a ball plunger 11 is embedded at one end of the reciprocating lead screw 5. The ball plunger 11 is eccentric relative to the axis of the reciprocating lead screw 5. The ball of the ball plunger 11 protrudes from the end face of the reciprocating lead screw 5 in the natural state. An arc groove (not shown in the figure) for the ball to enter is provided at the position of the support frame 4 opposite to the end face of the reciprocating lead screw 5. When the smooth segment 9 faces the synchronous gear 10, the ball of the ball plunger 11 enters the arc groove to limit the rotation of the reciprocating lead screw 5 relative to the support frame 4. When the tooth segment 8 faces the synchronous gear 10, the thrust of the tooth segment 8 pushing the synchronous gear 10 drives the ball to leave the arc groove, so that the reciprocating lead screw 5 can rotate together with the synchronizing member 7. When the tooth segment 8 leaves the synchronous gear 10, the ball and the arc groove are opposed and the ball re-enters the arc groove.

[0038] Referring to Figure 3 and Figure 4 , furthermore, the support frame 4 has a connecting portion 12. The connecting portion 12 enters the end face of the synchronizing member 7. A ring groove 13 for the connecting portion 12 to slide is coaxially provided on the end face of the synchronizing member 7. When the synchronizing member 7 rotates, the connecting portion 12 slides in the ring groove 13 to be able to determine the relative position between the synchronous gear 10 and the synchronizing member 7. The connecting portion 12 can be in the shape of a dovetail or a T shape to prevent the connecting portion 12 from disengaging from the ring groove 13. In this embodiment, the connecting portion 12 is preferably in the shape of a dovetail with a width gradually increasing along the inside of the synchronizing member 7.

[0039] Referring to Figure 1 , when the acoustic detection line is wound up, hold the handle 22 and rotate the side plate 3 and the winding shaft 2. The acoustic detection line is wound around the winding shaft 2 through the guide wheel 6. When the side plate 3 rotates, it drives the reciprocating lead screw 5 to rotate through the synchronizing member 7, so that the guide wheel 6 reciprocates axially along the reciprocating lead screw 5, so that the winding position of the acoustic detection line on the winding shaft 2 continuously changes, thereby improving the uniformity of the winding of the acoustic detection line on the winding shaft 2.

[0040] Referring to Figure 1 and Figure 3 , in addition, during the use of the acoustic detection line, water is injected into the acoustic detection tube, so that the surface of the acoustic detection line is with moisture. In order to improve the cleanliness of the wound acoustic detection line, a flexible water-absorbing strip 20 is abutted against the side of the limiting portion 18 facing the reciprocating lead screw 5. The flexible water-absorbing strip 20 is made of an elastic water-absorbing sponge material. The flexible water-absorbing strip 20 extends axially along the parallel winding shaft 2 and abuts against the acoustic detection line passing through the guide wheel 6. The acoustic detection line is slightly embedded in the flexible water-absorbing strip 20, so that the acoustic detection line absorbs water through the flexible water-absorbing strip 20 during the winding process.

[0041] One end of the flexible water-absorbing strip 20 is fixedly connected to one end of the support frame 4, and the other end is fixedly connected with an extension handle 21. The extension handle 21 is in an L shape and includes a first part 211 and a second part 212 that are perpendicular to each other. The first part 211 is rotatably connected to the support frame 4, and the second part 212 extends to face the end surface of the side plate 3, and the second part 212 is located on the moving path of the handle 22. When the handle 22 passes through the second part 212, the handle 22 pushes the second part 212 to swing, so that the first part 211 drives the flexible water-absorbing strip 20 to rotate relative to the support frame 4, so that the two ends of the flexible water-absorbing strip 20 are relatively twisted to supply water. When the handle 22 leaves the second part 212, the second part 212 is elastically reset by the flexible water-absorbing strip 20. The operator can also rotate the extension handle 21 by himself to drive the flexible water-absorbing strip 20 to squeeze water.

[0042] Referring to Figure 1 and Figure 3 , in order to facilitate the transducer connected to the acoustic wave detection line to pass between the flexible water-absorbing strip 20 and the guide wheel 6, the support frame 4 includes a first split body 41 and a second split body 42 that are detachably connected. Among them, the reciprocating lead screw 5 and the connecting part 12 are installed on the first split body 41, and the first split body 41 also serves as the basis for connecting to the base frame 1. The limiting part 18 is part of the second split body 42, and the flexible water-absorbing strip 20 and the extension handle 21 are installed on the second split body 42. The first split body 41 and the second split body 42 are detachably connected by bolts. When the acoustic wave detection line needs to be introduced into the guide wheel 6, first remove the second split body 42 from the first split body 41, clip the acoustic wave detection line into the guide groove 23, and then install the second split body 42 onto the first split body 41.

[0043] The implementation principle of the acoustic wave detection line recovery anti-winding device in the embodiment of the present application is: by rotating the handle 22 to drive the side plate 3 and the winding shaft 2 to wind up the acoustic wave detection line, the acoustic wave detection line moves axially back and forth along the winding shaft 2 during the winding process under the guidance of the guide wheel 6, and at the same time the flexible water-absorbing strip 20 absorbs water from the acoustic wave detection line passing through the guide wheel 6.

[0044] Embodiment Two: Since the auxiliary unit is detachably connected to the winding unit, the operator can transform the existing winding device by grooving, opening holes, etc. and install the auxiliary unit on other winding devices. In order to improve the accuracy of installing the auxiliary unit, a centering piece 16 is installed on the inner circumference of the synchronizing piece 7, which is used to assist the synchronizing piece 7 to be coaxial with the side plate 3 during installation.

[0045] Specifically, referring to Figure 6 and Figure 7, a plurality of centering pieces 16 are circumferentially installed along the inner circumference of the synchronizing member 7. Each centering piece 16 is in the shape of a square sheet, and one end is a hinged end. The hinged end of the centering piece 16 has a notch and a meshing gear 24 is fixed at the notch. A hinged seat 25 corresponding to the centering piece 16 is fixed on the inner circumference of the synchronizing member 7. The hinged end of the centering piece 16 is rotatably connected to the hinged seat 25. The rotation axis of the hinged end is parallel to the axis of the synchronizing member 7, and the meshing gear 24 is coaxial with the rotation axis of the centering piece 16.

[0046] A driving ring 17 rotates coaxially on the inner circumference of the synchronizing member 7. The driving ring 17 passes through the space between all the hinged seats 25 and the hinged ends, and the driving ring 17 is misaligned with the abutting column 14 at the same time. Teeth are evenly spaced along the circumferential direction of the inner circumference of the driving ring 17, and the driving ring 17 meshes with the hinged ends of all the centering pieces 16 at the same time. The angles between the hinged ends of all the centering pieces 16 and the driving ring 17 are all the same.

[0047] When determining the relative position between the synchronizing member 7 and the side plate 3, all the centering pieces 16 are driven to swing synchronously by rotating the driving ring 17. When the free ends of all the centering pieces 16 abut against the outer circumference of the side plate 3, the synchronizing member 7 and the side plate 3 are concentric. At this time, the abutting column 14 is threadedly moved so that the abutting column 14 abuts against the outer circumference of the side plate 3 to limit the synchronizing member 7.

[0048] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
