Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a mold for making a protective sleeve for a pile foundation acoustic logging pipe. Background Technology

[0002] To inspect the quality of concrete pile foundations, acoustic transducers are pre-embedded within the piles. Acoustic testing instruments are inserted into the pile through these transducers for testing. Current methods for protecting these transducers from objects falling in involve using a flexible object rolled into a ball and blocking the upper end of the transducer. However, this method lacks specialized protective devices. Furthermore, the method of using a rolled-up flexible object for blocking is prone to accidental insertion that can lead to difficulty in removal, and the protective effect is poor. Therefore, those skilled in the art have conducted research on protective technologies for acoustic transducers in pile foundations. Utility Model Content

[0003] The present invention aims to provide a mold for manufacturing a protective sleeve for a pile foundation acoustic logging pipe that can reliably protect the acoustic logging pipe of the pile foundation, thus solving the problem of the lack of a dedicated protective device for the acoustic logging pipe of the pile foundation.

[0004] To achieve the above objectives, this utility model employs the following technology: a mold for manufacturing a protective sleeve for a pile foundation sonic logging pipe, comprising a mold core and an outer mold with an open upper end fitted onto the lower end of the mold core. A cavity for forming the protective sleeve for the pile foundation sonic logging pipe is formed between the mold core and the outer mold. The protective sleeve for the pile foundation sonic logging pipe includes a sleeve for fitting onto the upper end of the pile foundation sonic logging pipe to close it. The sleeve includes a pipe body and a top wall closed at the upper end of the pipe body. The lower end of the pipe body is open to form an insertion port. The sleeve is an elastic structure capable of elastic expansion and contraction. A rigid gripping ring is connected to the insertion port. Several axially extending swing rods are provided within the pipe wall of the pipe body, distributed circumferentially. A rigid ring is provided at one end of the pipe body sidewall connected to the top wall. One end of each swing rod is rotatably fitted onto the rigid ring. The other end of each swing rod is provided with a pressing spring and a driving swing spring to move the swing rod towards the interior of the pipe body to press the pipe body against the pile foundation sonic logging pipe. A swing rod relaxation structure is provided on the rigid holding ring, which moves the rod away from the inside of the tube body. A suspension step is formed between the rigid holding ring and the tube body. The outer mold is provided with an outer mold suspension block for support on the suspension step. The mold core is provided with a mold core suspension block for suspension on the end of the rigid holding ring away from the tube body. The process of making the protective sleeve for the pile foundation sonic logging pipe is as follows: the outer mold is in the state of opening end facing upward. The swing rod assembled with the rigid ring is connected to the rigid holding ring as required. The swing rod is inserted into the outer mold and suspended on the outer mold suspension block through the suspension step. The mold core is inserted into the outer mold until the mold core suspension block is suspended on the end of the rigid holding ring away from the tube body. A cavity for forming the protective sleeve for the pile foundation sonic logging pipe is formed between the mold core and the outer mold, and the swing rod passes through the cavity. Molten material for making the sleeve is poured into the cavity from the top of the cavity and solidified to form the sleeve. When protecting the sonic logging tube for pile foundations, the sleeve is placed on the upper end of the tube with the insertion port facing downwards to seal it and prevent objects from falling into the tube. To remove or add the sleeve, the lever releases its pressure on the sleeve using the lever relaxation mechanism. Then, the rigid grip ring is held to slide the sleeve onto or remove it from the sonic logging tube. When the sleeve is on the tube, the spring action tightens it securely. The resulting sleeve can both fit tightly onto the sonic logging tube and be easily removed.

[0005] Preferably, the entire circumference of the insertion port is sealed and cast together with the rigid holding ring. This avoids gaps between the rigid holding ring and the sleeve, preventing interference with the sleeve's fit onto the pile foundation sonic logging pipe.

[0006] Preferably, the open end of the outer mold has an outward flange, which constitutes the suspension block of the outer mold part. The periphery of the outward flange has an upward flange, and in use, the outer circumferential surface of the rigid gripping ring abuts against the inner circumferential surface of the upward flange for positioning. The suspension block of the mold core part uses a downward flange, and in use, the outer circumferential surface of the rigid gripping ring abuts against the inner circumferential surface of the downward flange for positioning. This allows for positioning, facilitating the placement of the swing rod within the sleeve and ensuring the sleeve meets requirements.

[0007] Preferably, when the sleeve is fitted onto the sonic logging pipe of the pile foundation, the end of the swing rod connected to the rigid ring is pressed tightly onto the sleeve. This improves the tightening effect of the sleeve.

[0008] Preferably, the rigid ring is aligned with the top wall, allowing the pendulum to swing at a large amplitude.

[0009] Preferably, the rigid ring is provided with two retaining rings distributed on both sides of the swing arm. This prevents molten sleeve material from entering the rotating surfaces of the swing arm and the rigid ring during casting, thus affecting the swing arm's oscillation.

[0010] Preferably, the swing arm is provided with an annular sealing groove, and the outer edge of the retaining ring is provided with a sealing flange that passes through the annular sealing groove. The sealing flange is annular with the axis of the swing arm as its center line. This allows the swing arm to swing easily even though the sleeve is cast.

[0011] Preferably, a clearance gap is provided between the retaining ring and the swing arm. This allows the swing arm to swing with less effort.

[0012] Preferably, the rigid grip ring has receiving pits distributed circumferentially along the sleeve, located on the upper end face of the rigid grip ring. Each swing arm is correspondingly inserted into one of these receiving pits. The swing arm relaxation structure includes a rocker arm hinged within the receiving pit and a pressing pin abutting one end of the rocker arm, passing through the outer wall of the receiving pit. One end of a pressing spring presses against the other end of the rocker arm, and the other end connects to the inner surface of the outer wall of the receiving pit. The swing arm overlaps the side of the rocker arm facing the outer wall of the receiving pit. In use, holding all the pressing pins causes them to retract, driving the rocker arm to swing and overcoming the spring force of the pressing spring, thus driving the swing arm to swing in the release direction. When the pressing action on the pressing pins is lost, the rocker arm and swing arm return to their original positions under the action of the pressing spring.

[0013] Preferably, the device also includes an elastic gripping ring fitted onto the rigid gripping ring, with the outer end of the pressing pin connected to the inner circumferential surface of the elastic gripping ring. During use, gripping the elastic gripping ring to drive the pressing pin improves the reliability of simultaneously driving all pressing pins and enhances user comfort. Beneficial effects: It provides reliable protection for the acoustic waveguide of the pile foundation, preventing it from falling into the acoustic waveguide, and allows for nighttime identification.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] See Figure 1 to Figure 2A mold for manufacturing a protective sleeve for a pile foundation sonic logging pipe includes a core mold 19 and an outer mold 20, which is sleeved on the upper end of the core mold and has one open end. A cavity 21 is formed between the core mold and the outer mold to form the protective sleeve for the pile foundation sonic logging pipe. The protective sleeve for the pile foundation sonic logging pipe includes a sleeve 2 for being sleeved onto the upper end of the pile foundation sonic logging pipe 1 to seal the pipe. The sleeve includes a pipe body 3 and a top wall 4 that is closed on the upper end of the pipe body. The lower end of the pipe body is open to form an insertion port. A fluorescent strip is provided on the outer surface of the sleeve. In use, the sleeve is sleeved onto the upper end of the pile foundation sonic logging pipe with the insertion port facing downward to seal the pipe. The sleeve is an elastic structure (specifically rubber) that can elastically stretch and contract. A rigid gripping ring 5 is connected to the insertion port. Several swing rods 6 are provided inside the pipe body wall, which are distributed axially along the circumference of the pipe body. A rigid ring 7 is provided inside the end of the pipe body side wall that is connected to the top wall. One end of the swing rod is rotatably sleeved on the rigid ring. One end of the swing arm connected to the rigid ring is pressed against the sleeve. The rigid ring is aligned with the top wall. The sleeve is a cast-in-place component, and the rigid ring has two retaining rings 8 distributed on both sides of the swing arm. The swing arm has an annular sealing groove, and the outer edge of the retaining ring has a sealing flange 9 that passes through the annular sealing groove. The sealing flange is annular with the axis of the swing arm swinging as its center line. The other end of the swing arm has a pressing spring 10 that drives the swing arm to move towards the inside of the tube body and presses the tube body against the pile foundation sonic logging tube, and a swing arm relaxation structure 11 that drives the swing arm to move away from the inside of the tube body. When the sleeve needs to be removed or put on, the swing arm relaxation structure releases the pressing force on the sleeve, and then the rigid holding ring is held to put the sleeve on the pile foundation sonic logging tube or remove it. When the sleeve is put on the pile foundation sonic logging tube, the sleeve is tightened on the pile foundation sonic logging tube under the action of the pressing spring. The entire circumference of the insertion port is sealed and fixed together with the rigid holding ring. A clearance gap 12 is provided between the retaining ring and the swing arm. The rigid grip ring has receiving pits 13 distributed along the circumference of the sleeve. The receiving pits are located on the upper end surface of the rigid grip ring. The swing arms are correspondingly inserted into the receiving pits. The swing arm relaxation structure includes a rocker arm 15 hinged to the receiving pit by a hinge pin 14 and a pressing pin 17 that abuts against one end of the rocker arm and is inserted into the outer wall 16 of the receiving pit. One end of the pressing spring presses against the other end of the rocker arm, and the other end is connected to the inner surface of the outer wall of the receiving pit. The swing arm overlaps on the side of the rocker arm facing the outer wall of the receiving pit. In use, holding all the pressing pins causes the pressing pins to retract and drive the rocker arm to swing, overcoming the elastic force of the pressing spring, and thus driving the swing arm to swing in the release direction. When the pressing action on the pressing pins is lost, the rocker arm and the swing arm return to their original positions under the action of the pressing spring. It also includes an elastic grip ring 18 sleeved on the rigid grip ring, with the outer end of the pressing pin connected to the inner circumferential surface of the elastic grip ring. In use, the elastic grip ring is held to drive the pressing pin.A suspension step 22 is formed between the rigid gripping ring and the tube body. The outer mold is provided with an outer mold suspension block 23 for support on the suspension step. The open end of the outer mold is provided with an outward flange, which constitutes the outer mold suspension block. The periphery of the outward flange is provided with an upward flange 24. In use, the outer peripheral surface of the rigid gripping ring abuts against the inner peripheral surface of the upward flange for positioning. The mold core is provided with a mold core suspension block 25 for suspension on the end of the rigid gripping ring away from the tube body. The mold core suspension block is provided with a downward flange 26. In use, the outer peripheral surface of the rigid gripping ring abuts against the inner peripheral surface of the downward flange for positioning.

[0026] The process of making the protective sleeve for the pile foundation sonic logging pipe is as follows: the outer mold is in the state of having its open end facing upwards. The swing rod assembled with the rigid ring is connected to the rigid holding ring as required. The swing rod is inserted into the outer mold and suspended on the suspension block of the outer mold through the suspension step. The mold core is inserted into the outer mold until the mold core suspension block is suspended on the end of the rigid holding ring away from the pipe body. The mold core and the outer mold form a cavity for forming the protective sleeve for the pile foundation sonic logging pipe, and the swing rod passes through the cavity. The molten material for making the sleeve is poured into the cavity from the top of the cavity and solidified to form the sleeve.
