Technical Field
[0001] This invention relates to the field of silicon core tube performance testing technology, and specifically to a performance testing device for HDPE silicon core tubes. Background Technology
[0002] HDPE silicon core pipe, also known as high-density polyethylene silicon core pipe, is a new type of communication pipe made of high-density polyethylene as the base material and coated with a layer of silicone material on the inner wall. In modern engineering construction, especially in underground cable laying projects for communication and power, HDPE silicon core pipe has been widely used due to its excellent comprehensive performance. This type of pipe has many advantages such as smooth inner wall, high strength, and corrosion resistance, and can provide good protection and passage for cables. However, with the continuous improvement of engineering quality requirements and the in-depth research on material performance, the accurate testing of various key performance indicators of HDPE silicon core pipe has become increasingly important. Among them, friction performance and compressive strength are two crucial technical parameters.
[0003] Traditional methods for testing friction performance often involve manual operation, which is not only inefficient but also highly susceptible to human factors. It is difficult to ensure consistent testing conditions for products of different specifications and batches, making it impossible to achieve large-scale, high-efficiency quality control.
[0004] In terms of compressive strength testing, most existing equipment is complex in structure and cumbersome to operate. Furthermore, when changing samples, the equipment parameters need to be readjusted, which consumes a lot of time and manpower.
[0005] Therefore, the present invention provides a performance testing device for HDPE silicon core tubes to solve the above problems. Summary of the Invention
[0006] In view of the above situation and to overcome the defects of the prior art, the present invention provides an HDPE silicon core tube performance testing device to solve the problem of automatically detecting the friction performance of silicon core tubes and facilitating the testing of the compressive strength of silicon core tubes.
[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows:
[0008] A performance testing device for HDPE silicon core tubes includes a base plate, a sliding plate slidably connected to one end of the top of the base plate, a rotating retaining ring installed on the side wall of the middle portion of the sliding plate, a fixing plate fixedly installed on the side wall of the sliding plate, a pressing block slidably connected to one end face of the fixing plate, a friction arc block provided on the outer wall of the pressing block, a partition plate fixedly installed at the top of the middle portion of the base plate, a straightening ring installed on the outer wall of the partition plate, and an mounting plate fixedly installed at the other end of the top of the base plate. A core tube is fixedly installed on the outer wall of the mounting plate, and one end of the core tube is fixedly connected to the outer wall of the partition plate. The rotating retaining ring, the straightening ring, and the core tube are located on the same horizontal plane. This device can drive the silicon core tube to move by sliding the slide plate, and at the same time achieve bidirectional insertion with the core tube to detect the friction coefficient of the insertion. At the same time, by setting the rotating retaining ring and the friction arc block, the detection of friction and pressing can be integrated. The pressing block drives the friction arc block to press down to detect the compressive strength. At the same time, the rotating retaining ring can drive the silicon core tube to rotate to achieve friction with the outer wall of the friction arc block, simulating the real use environment, realizing the compressive strength and friction detection of the silicon core tube in both dynamic and static states. Through multiple detections, the accuracy of the data is ensured.
[0009] Preferably, a groove is formed on the inner wall of one end of the base plate, and a bidirectional lead screw is rotatably connected inside the groove. A slider is threadedly connected to the outer wall of the bidirectional lead screw. The top of the slider is fixedly connected to the bottom of the slide plate. One end of the bidirectional lead screw is fixedly connected to the output end of the pull-out motor. The pull-out motor is fixedly installed on the side wall of the base plate. When using this device, firstly, both ends of the silicon core tube are respectively clamped onto the inner wall of the rotating retaining ring. At this time, the friction arc block abuts against the outer wall of the silicon core tube, and the core tube is clamped into the inside of the core tube cylinder. By starting the pull-out motor, the bidirectional lead screw drives the slide plate to move, inserting the core tube into the inside of the silicon core tube.
[0010] Preferably, a through groove is formed on the inner wall of the core tube, and a pushing block is slidably connected inside the through groove. The pushing block is fixedly installed on the outer wall of the mounting cylinder, and the mounting cylinder is slidably connected inside the core tube. The pushing block can slide stably inside the through groove, and at the same time, it positions and restricts the sliding of the mounting cylinder, so that the mounting cylinder can only slide back and forth inside the core tube.
[0011] Preferably, the push block is threadedly connected to the outer wall of the mounting screw, the mounting screw is rotatably connected to the outer wall of one end of the mounting plate, and one end of the mounting screw is fixedly connected to the output end of the motor.
[0012] Preferably, a retaining plate is slidably connected to the inner wall of the mounting cylinder. One end of the retaining plate is located inside the mounting cylinder, and a tension spring is fixedly installed at the other end of the retaining plate. The other end of the tension spring is fixedly connected to the inner wall of the mounting cylinder. A push-off groove is formed on the inner wall of the retaining plate. A sliding frame is slidably connected inside the mounting cylinder. A push-off inclined block is fixedly installed at one end of the sliding frame, and the push-off inclined block matches the push-off groove. A force-bearing column is slidably connected to one side of the mounting cylinder, and the force-bearing column abuts against one side of the sliding frame. A reset shaft is slidably connected to one side of the mounting cylinder. A reset spring is fixedly installed on the outer wall of the reset shaft, and the other end of the reset spring is fixedly connected to the inner wall of the mounting cylinder. The reset shaft matches the other side of the sliding frame. When it is necessary to install the core tube and silicon core tube, this device inserts one end of the core tube into the interior of the mounting cylinder. At this time, the force-bearing column will push and displace, causing the force-bearing column to drive the sliding frame to move. The inclined block on the wall abuts against the abutting groove, thereby driving the clamping plate to move. At this time, the tension spring is in a stretched state, and one end of the sliding frame abuts against one end of the reset shaft. At this time, the motor is started, causing the mounting screw to drive the mounting cylinder to move, pushing the core tube to be inserted into the inside of the silicon core tube. The sliding plate moves synchronously, and the insertion is carried out in both directions. During disassembly, the reset of the mounting cylinder can make the reset shaft abut against the inner wall of the core tube cylinder, realizing the reset of the sliding frame, which is convenient for disassembly and removal. This device can avoid the phenomenon of bending deformation of the core tube by setting the core tube cylinder, and prevent bending of the core tube and silicon core tube during insertion. It is suitable for the installation of core tubes of various diameters. At the same time, the mounting cylinder can automatically clamp the core tube to prevent it from falling off, realizing the automatic clamping function. After the core tube is tested, it can be automatically disassembled for easy removal and observation. At the same time, this device can detect the friction performance of bidirectional insertion and detect the friction coefficient between the core tube and the inside of the silicon core tube.
[0013] Preferably, a reciprocating screw is rotatably connected to the outer wall of the top of the slide plate, one end of the reciprocating screw is fixedly connected to the output end of the pressing motor, the pressing motor is fixedly installed on the side wall of the slide plate, and a threaded abutment block is threadedly connected to the outer wall of the reciprocating screw.
[0014] Preferably, a pressing groove is formed on the outer wall of the fixing plate, and the threaded abutment block is slidably connected inside the pressing groove. An installation cavity is formed at the bottom of the fixing plate. Multiple pressing blocks are present, and a fixing block is fixedly installed on the top of each pressing block. The fixing block is located inside the pressing groove and matches the threaded abutment block. A pressing spring is fixedly installed on one side of the top of each pressing block, and the other end of the pressing spring is fixedly connected to the installation cavity. In the initial state, the friction arc block abuts against the outer wall of the silicon core tube, providing protection. After the core tube is fully inserted into the silicon core tube, this device is used to test the pressure resistance of the silicon core tube. The device activates a pressing motor, which drives a reciprocating screw to rotate. This causes the threaded abutment block on the outer wall of the screw to move back and forth. As the threaded abutment block moves, it abuts against a fixed block, causing the pressing block to move downwards and press against the silicon core tube, thus testing the silicon core tube's compressive strength. The device also features a friction arc block that protects the outer wall of the silicon core tube, preventing bending before testing or during core tube insertion. When compressive strength testing is required, the pressing motor is activated to perform automatic testing, integrating compressive strength testing and protection. After testing, the pressing block resets for easy reuse in future tests.
[0015] Preferably, an adjusting plate is fixedly installed at the bottom of the friction arc block, and an adjusting groove is formed on the outer wall of the adjusting plate; an adjusting screw is rotatably connected inside the pressing block, and an adjusting inclined block is threadedly connected to the outer wall of the adjusting screw, the adjusting inclined block matching the adjusting groove; by rotating the adjusting screw, the adjusting inclined block is displaced, the inclined surface of the adjusting inclined block and the abutting surface of the adjusting groove gradually increase, causing the friction arc block to move outward, thus changing the position of the friction arc block, making the device suitable for use with silicon core tubes of various diameters.
[0016] Preferably, a correction arc plate is rotatably connected inside the correction ring, and the outer wall of the correction arc plate is provided with external teeth. The external teeth mesh with a drive gear, and the drive gear is rotatably connected inside the correction ring. The drive gear is fixedly connected to the output end of the drive motor.
[0017] Preferably, a compensation arc plate is slidably connected inside the correction arc plate, and a compensation block is fixedly installed on the outer wall of the compensation arc plate. The compensation block is threadedly connected to the outer wall of the adjusting screw, and the adjusting screw is rotatably connected inside the correction arc plate. In order to avoid bending during core tube insertion and removal, which would affect observation and testing, this device uses a drive gear to rotate the correction arc plate, thereby correcting the core tube. Furthermore, to accommodate core tubes of various diameters, the adjusting screw is rotated to make the compensation arc plate abut against the outer wall of the core tube, achieving the correction function.
[0018] The beneficial effects of this invention are as follows:
[0019] 1. This device uses a sliding plate to move the silicon core tube, enabling bidirectional insertion and detection of the friction coefficient of the insertion. Simultaneously, by rotating the retaining ring and the friction arc block, it integrates friction detection and pressing. The pressing block drives the friction arc block downwards to detect compressive strength, while rotating the retaining ring causes the silicon core tube to rotate, rubbing against the outer wall of the friction arc block. This simulates a real-world environment, allowing for the detection of compressive strength and friction in both dynamic and static states of the silicon core tube. Multiple detection methods ensure data accuracy.
[0020] 2. This device, through the design of the core tube sleeve, can prevent the core tube from bending and deforming, and prevent bending during the insertion of the core tube and the silicon core tube. It is suitable for the installation of core tubes of various diameters. At the same time, the installation sleeve can automatically clamp the core tube to prevent it from falling off, achieving an automatic clamping function. After the core tube is tested, the device can automatically disassemble for easy removal and observation. In addition, this device can perform bidirectional insertion and can detect the friction performance of bidirectional insertion, as well as the friction coefficient between the core tube and the silicon core tube.
[0021] 3. This device, through the setting of friction arc blocks, can protect the outer wall of the silicon core tube, preventing bending of the silicon core tube before testing and when inserting core tubes. When it is necessary to test the compressive strength, the pressing motor is started to realize the automatic testing function, realizing the integrated operation of compressive strength testing and protection. After the test is completed, the pressing block is reset, which can facilitate the use of testing again.
[0022] 4. This device moves the adjusting block by rotating the adjusting screw. The inclined surface of the adjusting block and the top surface of the adjusting groove gradually increase, causing the friction arc block to move outward and thus changing the position of the friction arc block. This makes the device suitable for use with silicon core tubes of various diameters.
[0023] 5. To prevent bending during core tube insertion and removal, which would affect observation and testing, this device uses a drive gear to rotate the straightening arc plate, thus straightening the core tube. Furthermore, to accommodate core tubes of various diameters, the adjusting screw is rotated to allow the compensation arc plate to abut against the outer wall of the core tube, achieving the straightening function.

Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.
[0045] A performance testing device for HDPE silicon core pipes, as shown in the attached document. Figure 1-2 As shown, the system includes a base plate 1, a slide plate 2 slidably connected to one end of the top of the base plate 1, a rotating retaining ring 3 installed on the side wall of the middle part of the slide plate 2, a fixing plate 4 fixedly installed on the side wall of the slide plate 2, a pressing block 5 slidably connected to one end face of the fixing plate 4, a friction arc block 6 provided on the outer wall of the pressing block 5, a partition plate 8 fixedly installed at the top of the middle part of the base plate 1, a straightening ring 7 installed on the outer wall of the partition plate 8, an mounting plate 10 fixedly installed at the other end of the top of the base plate 1, a core tube 9 fixedly installed on the outer wall of the mounting plate 10, one end of the core tube 9 fixedly connected to the outer wall of the partition plate 8, and the rotating retaining ring 3 and the straightening ring 7 are also present. The silicon core tube 9 is located on the same horizontal plane. This device can drive the silicon core tube to move by sliding the slide plate 2, and at the same time realize bidirectional insertion with the core tube to detect the friction coefficient of the insertion. At the same time, by rotating the retaining ring 3 and the friction arc block 6, the friction detection and pressing can be integrated. The pressing block 5 drives the friction arc block 6 to press down to detect the compressive strength. At the same time, rotating the retaining ring 3 can drive the silicon core tube to rotate to realize friction with the outer wall of the friction arc block 6, simulating the real use environment, realizing the compressive strength and friction detection of the silicon core tube in both dynamic and static states. Through multiple detections, the accuracy of the data is guaranteed.
[0046] As attached Figure 1 and attached Figure 3As shown, a groove 101 is provided on the inner wall of one end of the base plate 1. A bidirectional lead screw 102 is rotatably connected inside the groove 101. A slider 103 is threadedly connected to the outer wall of the bidirectional lead screw 102. The top of the slider 103 is fixedly connected to the bottom of the slide plate 2. One end of the bidirectional lead screw 102 is fixedly connected to the output end of the pull-out motor 104. The pull-out motor 104 is fixedly installed on the side wall of the base plate 1. When using this device, firstly, both ends of the silicon core tube are respectively clamped onto the inner wall of the rotating retaining ring 3. At this time, the friction arc block 6 abuts against the outer wall of the silicon core tube, and the core tube is clamped into the inside of the core tube cylinder 9. By starting the pull-out motor 104, the bidirectional lead screw 102 drives the slide plate 2 to move, and the core tube is inserted into the inside of the silicon core tube.
[0047] As attached Figure 4 As shown, a through groove 901 is provided on the inner wall of the core tube 9. A push block 903 is slidably connected inside the through groove 901. The push block 903 is fixedly installed on the outer wall of the mounting cylinder 902. The mounting cylinder 902 is slidably connected inside the core tube 9. The push block 903 can slide stably inside the through groove 901, and at the same time, it positions and restricts the sliding of the mounting cylinder 902, so that the mounting cylinder 902 can only slide back and forth inside the core tube 9.
[0048] As attached Figure 4 As shown, the push block 903 is threadedly connected to the outer wall of the mounting screw 904, the mounting screw 904 is rotatably connected to the outer wall of one end of the mounting plate 10, and one end of the mounting screw 904 is fixedly connected to the output end of the motor.
[0049] As attached Figure 5As shown, a retaining plate 905 is slidably connected to the inner wall of the mounting cylinder 902. One end of the retaining plate 905 is located inside the mounting cylinder 902, and a tension spring 907 is fixedly installed at the other end of the retaining plate 905. The other end of the tension spring 907 is fixedly connected to the inner wall of the mounting cylinder 902. A push-off groove 906 is formed on the inner wall of the retaining plate 905. A sliding frame 908 is slidably connected inside the mounting cylinder 902. A push-off inclined block 909 is fixedly installed at one end of the sliding frame 908, and the push-off inclined block 909 matches the push-off groove 906. A sliding connection is also shown on one side of the mounting cylinder 902. The force-bearing column 910 abuts against one side of the sliding frame 908. A reset shaft 911 is slidably connected to one side of the mounting cylinder 902. A reset spring 912 is fixedly installed on the outer wall of the reset shaft 911, and the other end of the reset spring 912 is fixedly connected to the inner wall of the mounting cylinder 902. The reset shaft 911 matches the other side of the sliding frame 908. When installing a core tube or silicon core tube, one end of the core tube is inserted into the mounting cylinder 902. At this time, the force-bearing column 910 will displace, causing the force-bearing column 910 to drive the sliding frame 908 to move. Displacement occurs when the abutting inclined block 909 on the outer wall of the sliding frame 908 abuts against the abutting groove 906, thereby causing the clamping plate 905 to move. At this time, the tension spring 907 is in a stretched state, and one end of the sliding frame 908 abuts against one end of the reset shaft 911. The motor is then started, causing the mounting screw 904 to move the mounting cylinder 902, pushing the core tube into the interior of the silicon core tube. The sliding plate 2 moves synchronously, allowing for bidirectional insertion. Simultaneously, during disassembly, the reset of the mounting cylinder 902 allows the reset shaft 911 to abut against the inner wall of the core tube cylinder 9, realizing the displacement of the sliding frame 908. The device is designed for easy disassembly and retrieval. The core tube sleeve 9 prevents bending and deformation of the core tube, ensuring a smooth connection between the core tube and the silicon core tube. It is suitable for installing core tubes of various diameters. The mounting sleeve 902 automatically engages the core tube to prevent detachment, achieving an automatic engagement function. After testing, the core tube can be automatically disassembled for easy removal and observation. The device allows for bidirectional insertion, enabling the detection of frictional performance during bidirectional insertion and the coefficient of friction between the core tube and the silicon core tube.
[0050] As attached Figure 1 As shown, a reciprocating screw 201 is rotatably connected to the outer wall of the top of the slide plate 2. One end of the reciprocating screw 201 is fixedly connected to the output end of the pressing motor 202. The pressing motor 202 is fixedly installed on the side wall of the slide plate 2. A threaded abutment block 203 is threadedly connected to the outer wall of the reciprocating screw 201.
[0051] As attached Figure 6-7As shown, a pressing groove 401 is provided on the outer wall of the fixing plate 4, and a threaded abutment block 203 is slidably connected inside the pressing groove 401. An installation cavity 402 is provided at the bottom of the fixing plate 4. Multiple pressing blocks 5 are present, and a fixing block 501 is fixedly installed on the top of each pressing block 5. The fixing block 501 is located inside the pressing groove 401 and matches the threaded abutment block 203. A pressing spring 502 is fixedly installed on one side of the top of each pressing block 5, and the other end of the pressing spring 502 is fixedly connected to the installation cavity 402. In the initial state, the friction arc block 6 abuts against the outer wall of the silicon core tube, providing protection. After the core tube is fully inserted into the silicon core tube, in order to test the pressure resistance of the silicon core tube, the device is activated... Pressing the motor 202 causes it to drive the reciprocating screw 201 to rotate, causing the threaded abutment block 203 on its outer wall to move back and forth. When the threaded abutment block 203 moves, it will abut against the fixed block 501. At this time, the pressing block 5 will be forced to move downward, thus abutting the silicon core tube and testing its compressive strength. The device, through the setting of the friction arc block 6, can protect the outer wall of the silicon core tube, preventing bending of the silicon core tube before testing or when inserting the core tube. When it is necessary to test the compressive strength, the pressing motor 202 is started to realize the automatic testing function, and the compressive strength test and protection are integrated into one operation. After the test is completed, the pressing block 5 is reset, which can be used for testing again.
[0052] As attached Figure 8 As shown, an adjusting plate 601 is fixedly installed at the bottom of the friction arc block 6, and an adjusting groove 602 is provided on the outer wall of the adjusting plate 601; an adjusting screw 604 is rotatably connected inside the pressing block 5, and an adjusting inclined block 603 is threadedly connected to the outer wall of the adjusting screw 604, and the adjusting inclined block 603 matches the adjusting groove 602; by rotating the adjusting screw 604, the adjusting inclined block 603 is displaced, and the inclined surface of the adjusting inclined block 603 and the abutting surface of the adjusting groove 602 gradually increase, so that the friction arc block 6 is displaced outward, thereby changing the position of the friction arc block 6, making the device suitable for use with silicon core tubes of various diameters.
[0053] As attached Figure 9 As shown, a straightening arc plate 701 is rotatably connected inside the straightening ring 7. The outer wall of the straightening arc plate 701 is provided with external teeth, which mesh with the drive gear 702. The drive gear 702 is rotatably connected inside the straightening ring 7 and is fixedly connected to the output end of the drive motor.
[0054] As attached Figure 9-10As shown, a compensation arc plate 703 is slidably connected inside the correction arc plate 701. A compensation block 704 is fixedly installed on the outer wall of the compensation arc plate 703. The compensation block 704 is threadedly connected to the outer wall of the adjusting screw 705. The adjusting screw 705 is rotatably connected inside the correction arc plate 701. In order to avoid bending during the insertion and removal of the core tube, which would affect observation and testing, the device starts the drive gear 702, which drives the correction arc plate 701 to rotate, thereby correcting the core tube. At the same time, in order to be suitable for the correction of core tubes of various sizes and diameters, the adjusting screw 705 is rotated so that the compensation arc plate 703 abuts against the outer wall of the core tube, thereby achieving the correction function.
[0055] Working Principle: In use, the two ends of the silicon core tube are first secured to the inner wall of the rotating retaining ring 3. By rotating the adjusting screw 604, the adjusting wedge 603 is displaced, gradually increasing the angle between the inclined surface of the adjusting wedge 603 and the abutment surface of the adjusting groove 602. This causes the friction arc block 6 to move outward, changing its position and making the device suitable for silicon core tubes of various diameters. Simultaneously, the core tube is secured to the inside of the core tube cylinder 9. By activating the pull-out motor 104, the bidirectional screw 102 drives the sliding plate 2 to move, inserting the core tube into the silicon core. Inside the tube; when it is necessary to install the core tube and the silicon core tube, by inserting one end of the core tube into the interior of the mounting cylinder 902, the force-bearing column 910 will be displaced, causing the force-bearing column 910 to drive the sliding frame 908 to move. The abutting inclined block 909 on the outer wall of the sliding frame 908 abuts against the abutting groove 906, thereby driving the clamping plate 905 to move. At this time, the tension spring 907 is in a stretched state, and one end of the sliding frame 908 abuts against one end of the reset shaft 911. At this time, the motor is started, causing the mounting screw 904 to drive the mounting cylinder 902 to move, pushing the core tube to be inserted into the silicon core tube. Inside, the sliding plate 2 moves synchronously and is inserted in both directions. During disassembly, the reset of the mounting cylinder 902 allows the reset shaft 911 to abut against the inner wall of the core tube cylinder 9, thus resetting the sliding frame 908 for easy disassembly and removal. In the initial state, the friction arc block 6 abuts against the outer wall of the silicon core tube, providing protection. After the core tube is fully inserted into the silicon core tube, to test its pressure resistance, the device activates the pressing motor 202, causing the pressing motor 202 to drive the reciprocating screw 201 to rotate. The threaded abutment block 203 on its outer wall moves back and forth. When the threaded abutment block 203 is displaced, it will abut against the fixed block 501. At this time, the pressing block 5 will be displaced downward under force to abut against the silicon core tube, thereby testing the compressive strength of the silicon core tube. In order to avoid bending during core tube insertion and removal, which would affect observation and testing, the drive gear 702 is activated to drive the straightening arc plate 701 to rotate, thereby straightening the core tube. At the same time, in order to be suitable for the straightening of core tubes of various sizes and diameters, the adjusting screw 705 is rotated to make the compensating arc plate 703 abut against the outer wall of the core tube, thereby achieving the straightening function.
