Description

Technical Field

[0001] This utility model relates to the fields of industrial production and scientific research, and in particular to a test device for bursting of large-diameter hoses. Background Technology

[0002] A burst test apparatus is a device used to test the burst performance of large-diameter hoses under high pressure. This apparatus can help evaluate the safety and reliability of the hoses.

[0003] In industrial production and scientific research, burst testing of large-diameter hoses is a crucial method for assessing their pressure-bearing capacity. A burst testing machine applies progressively increasing pressure to the hose until it ruptures, obtaining the hose's ultimate pressure-bearing parameters. This provides a basis for quality assessment and selection of the large-diameter hose. Currently, existing burst testing devices typically use a conventional threaded connection to connect one end of the hose to the outlet pipe on one side of the burst testing machine. During actual burst testing, as the internal pressure increases, the hose experiences significant axial tensile and radial expansion forces. Because this conventional connection relies solely on the friction between the threads for fixation, lacking additional limiting protection, the hose is highly susceptible to slippage and detachment from the outlet pipe. If the hose detaches, it not only prevents the burst test from proceeding normally, interrupting the test process and affecting the integrity and accuracy of the data, but also poses a significant safety hazard due to the high-speed jet of water or fluid potentially damaging the test site and personnel. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing large-diameter hose burst test devices typically use only a conventional threaded connection to connect one end of the large-diameter hose body to the outlet pipe on one side of the burst test machine. During actual burst tests, as the internal pressure increases, the large-diameter hose body experiences significant axial tensile and radial expansion forces. Because this conventional connection relies solely on the friction between the threads for fixation, lacking additional limiting protection, the large-diameter hose body is highly susceptible to slippage and detachment from the outlet pipe. Once the large-diameter hose body detaches, it not only prevents the burst test from proceeding normally, interrupting the test process and affecting the integrity and accuracy of the data, but also poses a significant safety hazard due to the high-speed jet of water or fluid potentially endangering the test site and personnel.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a large-diameter hose burst test device, including a burst test machine and a large-diameter hose body. A water outlet pipe is provided on one side of the inner wall of the burst test machine. One end of the large-diameter hose body is spirally sleeved and installed on the outer surface of the water outlet pipe. A limiting and fixing device is provided on the outer surface of the water outlet pipe. The limiting and fixing device can be inserted into the rectangular groove on the outer surface of one end of the large-diameter hose body by a limiting block and a rectangular block under the reset action of a spring, thereby performing secondary limiting and fixing on the outer surface of one end of the large-diameter hose body that is spirally screwed onto the water outlet pipe, achieving the effect of preventing detachment.

[0006] The effect achieved by the above components is as follows: When conducting a water-injection pressurization burst test on a large-diameter hose using a burst testing machine, one end of the large-diameter hose is sealed off. The sealing method is not fixed. Then, a limiting and fixing device is fitted onto the outer surface of the outlet pipe, and the other end is spirally fitted onto the outer surface of the outlet pipe until one side abuts against the limiting and fixing device. The limiting and fixing device then provides secondary limiting and fixing to the surface, limiting and locking the rotation direction of one end of the large-diameter hose body. Thus, during the burst test, as… The continuously increasing internal pressure also reduces the likelihood of the large-diameter hose body slipping and detaching from the outlet pipe, thus avoiding test interruptions, improving the integrity and accuracy of test data, and reducing safety hazards caused by detachment. During the burst test, the burst test machine can be started, and its internal water pump can draw water from the internal water tank into the outlet pipe, and then into the interior of the large-diameter hose to increase the burst test treatment until the surface of the large-diameter hose bursts, thereby obtaining the hose's ultimate pressure bearing parameters and providing a basis for hose quality assessment and selection.

[0007] Preferably, the limiting and fixing device includes a circular ring block, wherein the inner wall of the circular ring block is fitted onto the outer surface of the water outlet pipe, and an auxiliary mechanism is provided between the inner wall and the outer surface of the water outlet pipe; the outer surface of the circular ring block is symmetrically provided with sliding grooves; two limiting blocks, wherein one end of the limiting block is slidably installed in the inner wall of the sliding groove; two springs, wherein the two ends of the springs are respectively fixedly installed on one side of the limiting block and one side of the inner wall of the sliding groove; two rectangular blocks, wherein one side of the rectangular blocks is fixedly installed on one side of the limiting block; the outer surface of the large-diameter hose body is provided with several rectangular grooves, wherein one end of the rectangular block is inserted into the inner wall of the rectangular groove.

[0008] The aforementioned components achieve the following effects: By setting a limiting and fixing device, before testing, the ring block can be fixed to the outer surface of the water outlet pipe through an auxiliary mechanism, making it difficult for it to rotate on the outer surface of the water outlet pipe. At this time, the limiting block is pulled outward in the inner wall of the groove to a certain position, causing the spring to stretch. Then, one end of the large-diameter hose body is spirally fitted onto the outer surface of the water outlet pipe until one side abuts against the ring block, fixing and pressing the ring block against the outer surface of the water outlet pipe. At this time, the limiting block is released, so that one side abuts against the outer surface of one end of the large-diameter hose body. At the same time, the rectangular block on one side will be inserted into the corresponding rectangular groove, providing secondary limiting and fixing for one end of the installed large-diameter hose body, making it difficult for it to rotate and avoiding slippage and detachment, thus improving the stability of the connection. In this way, during the burst test, as the internal pressure continuously increases, it is less likely for the large-diameter hose body to slip and detach from the water outlet pipe, avoiding test interruption, improving the integrity and accuracy of test data, and reducing the safety hazards caused by detachment.

[0009] Preferably, the limiting and fixing device further includes two support rods, one side of which is fixedly installed on one side of the inner wall of the slide groove, while the other end passes through the inner wall of the spring and is slidably connected to the inner wall of the limiting block.

[0010] The effect achieved by the above components is that by setting support rods, the inner walls of the limiting block and the spring can be supported and reinforced, making them less prone to damage during use.

[0011] Preferably, a pull block is fixedly installed on the outer surface of the limiting block, and the cross-section of the pull block is L-shaped.

[0012] The effect achieved by the above components is as follows: by setting the pull block, the contact area on one side of the limiting block can be increased, so that when it is necessary to pull the limiting block to both sides, the pull block can be grasped or pushed outward against one side of the pull block, thereby making it convenient to pull the limiting block to both sides and making operation convenient.

[0013] Preferably, a sealing block is fixedly installed on one side of the annular block, and the sealing block is made of rubber.

[0014] The effect achieved by the above-mentioned components is as follows: by setting a sealing block, after one end of the large-diameter hose is spirally sleeved on the outer surface of the water outlet pipe, when one side abuts against one side of the ring block, the sealing block will be squeezed and deformed, sealing and blocking the gap between the ring block and one side of the large-diameter hose body. At the same time, it can also seal and block the gap between the ring block and the water outlet pipe, preventing water leakage during water injection and pressurization, and improving the detection effect.

[0015] Preferably, the auxiliary mechanism includes two locking blocks, one side of which is fixedly installed in the inner wall of the annular block, and the outer surface of the water outlet pipe is symmetrically provided with locking grooves, wherein the locking blocks are inserted into the inner wall of the locking grooves.

[0016] The effect achieved by the above-mentioned components is as follows: By setting an auxiliary mechanism, when the ring block is installed on the outer surface of the water outlet pipe, the locking block in the inner wall of the ring block can be inserted into the locking groove to limit the ring block on the outer surface of the water outlet pipe, making it difficult for it to rotate. In this way, when installing the large-diameter hose body, the ring block can be abutted and fixed on the water outlet pipe, and at the same time, the large-diameter hose body is secondary limited and fixed, making it less likely to rotate and slip off after installation, thus improving the stability of the installation.

[0017] Preferably, an anti-slip block is fixedly installed on the outer surface of the card block, and the anti-slip block is made of silicone.

[0018] The effect achieved by the above components is as follows: by setting anti-slip blocks, the contact friction of the outer surface of the card block can be increased, making it more secure when it is inserted into the card slot and less prone to shaking. At the same time, it can also seal the gap between the card block and the card slot.

[0019] Preferably, one end of the card block has a trapezoidal longitudinal section, and the trapezoidal end of the card block is located at the end away from the rectangular block.

[0020] The effect achieved by the above components is that by setting one end of the card block in a trapezoidal shape, the area of ​​one end of the card block can be reduced, making it easier to quickly align with the card slot and insert it, thus facilitating installation.

[0021] The beneficial effects of this utility model are:

[0022] By setting a limiting and fixing device, before testing, the ring block can be fixed to the outer surface of the water outlet pipe through an auxiliary mechanism, making it difficult for it to rotate on the outer surface of the water outlet pipe. At this time, the limiting block is pulled outward in the inner wall of the groove to a certain position, causing the spring to stretch. Then, one end of the large-diameter hose body is spirally sleeved on the outer surface of the water outlet pipe until one side abuts against the ring block, fixing and pressing the ring block against the outer surface of the water outlet pipe. At this time, the limiting block is released, so that one side abuts against the outer surface of one end of the large-diameter hose body. At the same time, the rectangular block on one side will be inserted into the corresponding rectangular groove, providing a second limiting and fixing for one end of the installed large-diameter hose body, making it difficult for it to rotate and preventing slippage and detachment. This improves the stability of the connection. In this way, during the burst test, as the internal pressure continues to rise, it is less likely for the large-diameter hose body to slip and detach from the water outlet pipe, avoiding test interruption, improving the integrity and accuracy of test data, and reducing the safety hazards caused by detachment.

Detailed Implementation

[0032] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] Figure 1-7The large-diameter hose burst test device shown includes a burst test machine 1 and a large-diameter hose body 4. A water outlet pipe 3 is provided on one side of the inner wall of the burst test machine 1. One end of the large-diameter hose body 4 is spirally sleeved on the outer surface of the water outlet pipe 3. A limiting and fixing device 2 is provided on the outer surface of the water outlet pipe 3. The limiting and fixing device 2 can be inserted into the rectangular groove 27 on the outer surface of one end of the large-diameter hose body 4 by the limiting block 25 and the rectangular block 26 under the reset action of the spring 24, so as to perform secondary limiting and fixing on the outer surface of one end of the large-diameter hose body 4 that is spirally screwed on the water outlet pipe 3, thereby achieving the effect of preventing it from falling off. When conducting a water-injection pressurization burst test on a large-diameter hose using the burst test machine 1, one end of the hose is sealed off. The sealing method is not fixed. Then, the limiting and fixing device 2 is fitted onto the outer surface of the outlet pipe 3. The other end is then spirally fitted onto the outer surface of the outlet pipe 3 until one side abuts against the limiting and fixing device 2. The limiting and fixing device 2 then provides secondary limiting and fixing to the surface, restricting and locking the rotation direction of one end of the large-diameter hose body 4. Thus, during the burst test, as the internal pressure increases... The increased pressure makes it less likely that the main body 4 of the large-diameter hose will slip and fall off the outlet pipe 3, thus avoiding test interruption, improving the integrity and accuracy of test data, and reducing the safety hazards caused by detachment. During the burst test, the burst test machine 1 can be started to pump water from the internal water tank into the outlet pipe 3, and then into the interior of the large-diameter hose to increase the burst test treatment until the surface of the large-diameter hose bursts, so as to obtain the ultimate pressure bearing parameters of the hose, and provide a basis for hose quality assessment and selection.

[0035] Figure 1-7The limiting and fixing device 2 shown includes a circular ring block 21, wherein the inner wall of the circular ring block 21 is fitted onto the outer surface of the water outlet pipe 3, and an auxiliary mechanism 22 is provided between the inner wall and the outer surface of the water outlet pipe 3. The outer surface of the circular ring block 21 is symmetrically provided with sliding grooves 23; two limiting blocks 25, wherein one end of the limiting block 25 is slidably installed in the inner wall of the sliding groove 23; two springs 24, wherein the two ends of the springs 24 are respectively fixedly installed on one side of the limiting block 25 and one side of the inner wall of the sliding groove 23; two rectangular blocks 26, wherein one side of the rectangular block 26 is fixedly installed on one side of the limiting block 25. The outer surface of the large-diameter hose body 4 is provided with several rectangular grooves 27, wherein one end of the rectangular block 26 is inserted into the inner wall of the rectangular groove 27. By setting the limiting and fixing device 2, before testing, the ring block 21 can be fixed to the outer surface of the water outlet pipe 3 through the auxiliary mechanism 22, making it difficult for it to rotate on the outer surface of the water outlet pipe 3. At this time, the limiting block 25 is pulled outward in the inner wall of the slide groove 23 to a certain position, causing the spring 24 to be stretched. Then, one end of the large-diameter hose body 4 is spirally sleeved on the outer surface of the water outlet pipe 3 until one side abuts against the ring block 21, fixing and pressing the ring block 21 against the outer surface of the water outlet pipe 3. At this time, the limiting block 25 is released, so that one side abuts against the... On the outer surface of one end of the large-diameter hose body 4, a rectangular block 26 on one side will simultaneously engage with a corresponding rectangular groove 27, thereby providing secondary positioning and fixation for one end of the installed large-diameter hose body 4, making it less prone to rotation and preventing slippage and detachment. This improves the stability of the connection. In this way, during the burst test, as the internal pressure continuously increases, it is less likely that the large-diameter hose body 4 will slip and detach from the water outlet pipe 3, avoiding test interruption, improving the integrity and accuracy of test data, and reducing the safety hazards caused by detachment.

[0036] Figure 1-7The limiting and fixing device 2 shown also includes two support rods 28. One side of the support rod 28 is fixedly installed on one side of the inner wall of the slide groove 23, while the other end passes through the inner wall of the spring 24 and slides to connect with the inner wall of the limiting block 25. By setting the support rods 28, the inner walls of the limiting block 25 and the spring 24 can be supported and reinforced, making them less prone to damage during use. A pull block 29 is fixedly installed on the outer surface of the limiting block 25. The pull block 29 has an L-shaped cross-section. By setting the pull block 29, the contact area on one side of the limiting block 25 can be increased, so that when it is necessary to pull the limiting block 25 to both sides, the pull block 29 can be grasped or pushed outward against one side of the pull block 29, thus facilitating the pulling and pushing of the limiting block 25 to both sides, making operation convenient. A sealing block 210 is fixedly installed on one side of the ring block 21. The sealing block 210 is made of rubber. By setting a sealing block 210, after one end of the large-diameter hose is spirally sleeved on the outer surface of the water outlet pipe 3, when one side abuts against one side of the ring block 21, the sealing block 210 will be squeezed and deformed, sealing and blocking the gap between the ring block 21 and one side of the large-diameter hose body 4. At the same time, it can also seal and block the gap between the ring block 21 and the water outlet pipe 3, preventing water leakage during water injection and pressurization, and improving the detection effect.

[0037] Figure 1-7 The auxiliary mechanism 22 shown includes two locking blocks 222, one side of which is fixedly installed in the inner wall of the annular block 21. The outer surface of the water outlet pipe 3 is symmetrically provided with locking grooves 221, in which the locking blocks 222 are inserted into the inner wall of the grooves 221. By setting the auxiliary mechanism 22, when the annular block 21 is installed on the outer surface of the water outlet pipe 3, the locking blocks 222 in the inner wall of the annular block 21 can be inserted into the grooves 221, limiting the annular block 21 to the outer surface of the water outlet pipe 3, making it difficult for it to rotate. Thus, when installing the large-diameter hose body 4, the annular block 21 can be abutted and fixed onto the water outlet pipe 3, and simultaneously, the large-diameter hose body 4 is secondary-limited and fixed, making it less prone to rotation and slippage after installation, thus improving the stability of the installation.

[0038] Figure 1-7 The outer surface of the shown locking block 222 is fixedly fitted with an anti-slip block 223, which is made of silicone. By setting the anti-slip block 223, the contact friction of the outer surface of the locking block 222 is increased, making it more secure when it is locked into the slot 221, preventing wobbling. It also seals the gap between the locking block 222 and the slot 221. One end of the locking block 222 has a trapezoidal cross-section, and this trapezoidal end is located at the end furthest from the rectangular block 26. By making one end of the locking block 222 trapezoidal, the area of ​​that end is reduced, facilitating quick alignment with the slot 221 and insertion, thus simplifying installation.

[0039] Working principle: When using the burst test machine 1 to conduct a water injection pressurization burst test on a large-diameter hose, one end of the large-diameter hose will be sealed. The sealing method is not fixed. Before the test, the locking block 222 in the inner wall of the annular block 21 can be inserted into the locking groove 221 to limit the annular block 21 to the outer surface of the outlet pipe 3, making it difficult for it to rotate. At this time, the limiting block 25 is pulled outward in the inner wall of the sliding groove 23 to a certain position, causing the spring 24 to be stretched. Then, one end of the large-diameter hose body 4 is spirally sleeved on the outer surface of the outlet pipe 3 until one side abuts against the sealing block 210 on the annular block 21, fixing and pressing the annular block 21 against the outer surface of the outlet pipe 3. At this time, the limiting block 25 is released, so that one side abuts against the outer surface of one end of the large-diameter hose body 4, and at the same time, the rectangular block on one side... Block 26 will fit into the corresponding rectangular groove 27, providing secondary positioning and fixation for one end of the installed large-diameter hose body 4, making it less prone to rotation and preventing slippage and detachment, thus improving the stability of the connection. This also prevents slippage and detachment of the large-diameter hose body 4 from the outlet pipe 3 during burst testing as the internal pressure increases, avoiding test interruption, improving the integrity and accuracy of test data, and reducing safety hazards caused by detachment. During burst testing, the burst testing machine 1 can be started, causing its internal water pump to draw water from the internal water tank into the outlet pipe 3, and then into the interior of the large-diameter hose to increase the burst test intensity until the surface of the large-diameter hose bursts, thereby obtaining the hose's ultimate pressure bearing parameters and providing a basis for hose quality assessment and selection.

[0040] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
