Description

Technical Field

[0001] This utility model belongs to the field of anti-clogging of acoustic logging pipes, and specifically relates to an anti-clogging device for acoustic logging pipes. Background Technology

[0002] Sonic logging tubes are indispensable equipment in modern pile foundation engineering. They serve as the channel through which the probe enters the pile body during ultrasonic testing of cast-in-place piles, and are a crucial component of the ultrasonic testing system. Due to the complex environment at the construction site, soil and concrete pouring processes can easily cause blockages in the logging tubes. Therefore, anti-blocking devices are needed to prevent concrete from entering and clogging the tubes.

[0003] Problems with existing technology:

[0004] The prior art, disclosed in CN216475237U, "An anti-clogging device for a sonic logging pipe," "includes a cover, at least two clamping arms, and a telescopic device; the cover has a sealing surface and a mounting surface arranged opposite to each other, the sealing surface of the cover is used to seal the opening of the sonic logging pipe; the clamping arms are respectively disposed on the periphery of the cover, each clamping arm has a connecting end and a clamping end, and each clamping arm is rotatably connected to the cover at the middle position between the clamping end and the connecting end; the telescopic device is installed on the mounting surface of the cover, and the telescopic device can drive the connecting end of the clamping arm to move, thereby driving the clamping end of the clamping arm to clamp and fix the sonic logging pipe."

[0005] In the above-mentioned device, since the anti-blocking device is installed on the top of the sonic logging pipe, it will cause an impact when the sonic logging pipe is installed with the reinforcing cage, thus affecting the normal use of the sonic logging pipe. At the same time, the clamping arm and telescopic device in the above-mentioned device need to be fixed to the sonic logging pipe with bolts, which makes the installation and removal of the anti-blocking device inconvenient. Utility Model Content

[0006] The purpose of this utility model is to provide a sonic logging pipe anti-blocking device, which can solve the problems of existing sonic logging pipe anti-blocking devices being directly installed on the top of the sonic logging pipe, affecting the installation of the sonic logging pipe and the reinforcing cage, and the anti-blocking device being not simple and convenient to install and remove.

[0007] The specific technical solution adopted by this utility model is as follows:

[0008] A device for preventing blockage of a sonic logging tube includes a stopper disposed outside an adjusting rod and sleeved with the adjusting rod, wherein a base plate is provided at the bottom of the adjusting rod and a locking sleeve is provided at the top of the stopper;

[0009] The adjusting rod is provided with a support mechanism on the side facing away from the stop, and a blocking mechanism is provided on the side facing away from the bottom plate.

[0010] The support mechanism includes a stationary plate and a moving plate, and the adjusting rod is used to drive the moving plate to rotate on top of the stationary plate;

[0011] The stationary disk includes a mounting groove and a support member. The mounting groove passes through the stationary disk, and the support member is slidably installed with the stationary disk through a sliding column fixedly connected to one end of the support member.

[0012] The moving plate includes a limiting groove and a through groove. The limiting groove is used to drive the sliding column to slide inside the mounting groove, and the adjusting rod is inserted into the through groove.

[0013] The blocking mechanism includes a base, a hinged seat, and a linkage component. The bottom of the base is hinged to a side plate via the hinged seat, and the side plate is hinged to the bottom plate via the linkage component.

[0014] The inner wall of the mounting groove is provided with a sliding groove for sliding installation of the sliding column. The support members are arranged around the inside of the stationary plate, and the support members are made to abut against the inner wall of the acoustic tube by means of the sliding column.

[0015] A fixing rod is fixedly connected to the bottom of the stationary plate, so that the stationary plate is fixedly connected to the blocking mechanism.

[0016] The adjusting rod and the through groove 422 are connected by a locking block and a locking slot.

[0017] An anchor rod is welded to the bottom of the stop, and the base and the stop are fixedly connected by the anchor rod.

[0018] The technical effects achieved by this utility model are as follows:

[0019] This invention utilizes a support mechanism located outside the adjusting rod, consisting of a moving plate and a stationary plate. When in use, rotating the adjusting rod causes the moving plate to rotate on the surface of the stationary plate, thereby causing the limiting groove of the moving plate to push the sliding column to slide inside the mounting groove and drive the support component to move synchronously. During the movement of the support component, one side of its arc surface fits against the inner wall of the sonic logging pipe, thus fixing the leak-proof device inside the sonic logging pipe. Therefore, since the support mechanism is located inside the sonic logging pipe, this invention does not affect the normal installation and fixation of the sonic logging pipe during use.

[0020] This invention features a base fitted to the outside of an adjusting rod. Side plates are hinged to the bottom of the base via hinged seats, and these side plates are hinged to a bottom plate via a linkage. Pulling the adjusting rod upwards causes the bottom plate to move upwards, which in turn pushes the side plates open under the action of the linkage. Since both the side plates and the outer surfaces of the base are curved, they abut against the inner wall of the sonic logging pipe, thus sealing the upper end of the pipe and preventing concrete from entering and clogging it during subsequent pile casting. Furthermore, the anti-clogging device can be easily installed and removed by rotating and pulling the adjusting rod. Attached Figure Description

[0027] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0028] like Figure 1-4 As shown, a sonic logging tube anti-blocking device includes a stop 2 disposed outside the adjusting rod 1 and sleeved with the adjusting rod 1. A base plate 3 is provided at the bottom of the adjusting rod 1, and a locking sleeve 6 is provided at the top of the stop 2.

[0029] Among them, a support mechanism 4 is provided on the side of the adjusting rod 1 that is away from the stop 2, and a blocking mechanism 5 is provided on the side of the adjusting rod 1 that is away from the bottom plate 3.

[0030] The support mechanism 4 includes a stationary plate 41 and a moving plate 42. The adjusting rod 1 is used to drive the moving plate 42 to rotate on the top of the stationary plate 41.

[0031] The stationary plate 41 includes a mounting groove 411 and a support member 413. The mounting groove 411 passes through the stationary plate 41, and the support member 413 is slidably installed with the stationary plate 41 through a sliding column 412 fixedly connected to one end of the support member 413.

[0032] The moving plate 42 includes a limiting groove 421 and a through groove 422. The limiting groove 421 is used to drive the sliding column 412 to slide inside the mounting groove 411, and the adjusting rod 1 is inserted into the through groove 422.

[0033] See attached document Figure 1 and Figure 4 In this embodiment, the blocking mechanism 5 includes a base 51, a hinge seat 52, and a linkage member 54. The bottom of the base 51 is hinged to a side plate 53 via the hinge seat 52, and the side plate 53 is hinged to the bottom plate 3 via the linkage member 54.

[0034] In the above embodiment, the base plate 3 can be moved upward by adjusting rod 1. Therefore, under the action of linkage 54 installed on the top of the base plate 3, the side plate 53 can be lifted and unfolded, so that the base 51 and the side plate 53 abut against the inner wall of the sonic logging pipe. The base 51 and the side plate 53 can seal the sonic logging pipe and prevent concrete from entering the sonic logging pipe and causing blockage during the pouring process.

[0035] Furthermore, an anchor rod is welded to the bottom of the stop 2, and the base 51 is fixedly connected to the stop 2 through the anchor rod.

[0036] The anti-blocking device can be placed on the acoustic tube by the stop 2. The base 51 is fixed by the action of the anchor rod, so the base 51 will not be driven to rotate synchronously when the adjusting rod 1 rotates.

[0037] Furthermore, since pre-drilled holes are provided on the top of both the base 51 and the side plate 53, extension plates can be added to the base 51 and the side plate 53, making the anti-blocking device suitable for installation and use with sonic logging pipes of different sizes.

[0038] See attached document Figure 1 , Figure 2 and Figure 3 In this embodiment, the inner wall of the mounting groove 411 is provided with a sliding groove for sliding installation of the sliding column 412. The support member 413 is arranged around the inside of the stationary plate 41, and the support member 413 is made to abut against the inner wall of the acoustic tube through the sliding column 412.

[0039] In the above embodiment, the sliding column 412 is welded to the support member 413, and the support member 413 is slidably installed inside the stationary plate 41. Therefore, under the action of the moving plate 42, the sliding column 412 can be driven to move, thereby causing the support member 413 to unfold outward inside the stationary plate 41 and push the outer arc surface of the support member 413 to abut against the inner wall of the acoustic tube.

[0040] Furthermore, since a fixing rod is welded to the bottom of the stationary plate 41, the stationary plate 41 can be fixedly connected to the blocking mechanism 5 under the action of the fixing rod. Because the blocking mechanism 5 will not rotate under the action of the anchor rod, the stationary plate 41 can be kept in a fixed state.

[0041] More specifically, the adjusting rod 1 and the through slot 422 are connected by a locking block and a locking slot.

[0042] The locking block on the side of the adjusting rod 1 can be inserted into the slot inside the through groove 422. When the adjusting rod 1 rotates, the moving plate 42 can be driven to rotate through the linkage between the locking block and the slot. The moving plate 42 can drive the limiting groove 421 to rotate, thereby pushing the sliding column 412 inside it to slide inside the mounting groove 411.

[0043] See attached document Figure 1 It is worth noting that a bearing sleeve is connected between the stop 2 and the adjusting rod 1, and a locking sleeve 6 is fixedly connected to the top of the stop 2. The locking sleeve 6 is rotatably connected to the adjusting rod 1 by a bearing. Therefore, the rotation and vertical movement of the adjusting rod 1 can be limited by the locking bolt connected by the thread on the side of the locking sleeve 6.

[0044] The working principle of this utility model is as follows: by using the stop 2 to attach the anti-blocking device to the top of the sonic logging tube, the support mechanism 4 and the blocking mechanism 5 will enter the inside of the sonic logging tube. By rotating the locking bolt, the locking sleeve 6 will release the restriction on the adjusting rod 1. By rotating the adjusting rod 1, it will be lifted upwards simultaneously.

[0045] When the adjusting rod 1 rotates, the moving plate 42 is driven to rotate by the cooperation of the locking block installed on its side and the locking groove opened inside the through groove 422. Since the sliding column 412 slidably installed inside the stationary plate 41 is located in the limiting groove 421 of the moving plate 42, the sliding column 412 is pushed to move inside the mounting groove 411 through the limiting groove 421, thereby pushing the support member 413 to move outward and driving the support member 413 to abut against the inner wall of the acoustic tube, thereby completing the fixation of the anti-blocking device.

[0046] When the adjusting rod 1 is pulled upward, the action of the base plate 3 can drive one end of the linkage 54 to move upward. At this time, the other end of the linkage 54 is fixedly connected to the side plate 53, causing the side plate 53 to be lifted and unfolded, thereby forming a disc shape with the base 51 and abutting against the inner wall of the sonic logging tube. By rotating the locking bolt, the locking sleeve 6 can restrict the stop 2, thereby sealing the sonic logging tube and preventing concrete from falling in and causing blockage of the sonic logging tube during the pile pouring process.

[0047] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
