Description

Technical Field

[0001] This utility model relates to the technical field of hydrostatic testing equipment for water pipelines, and specifically to a high-pressure pipe receiver. Background Technology

[0002] As a core component of water supply pipeline inspection, the accuracy of hydrostatic testing directly impacts product quality assessment. Existing testing systems with fixed water tanks exhibit significant technical deficiencies: test samples of varying specifications are susceptible to collisions due to water flow impacts or buoyancy during testing due to the lack of dynamically adaptable fixed support devices, leading to external damage and frequent sample replacements, thus extending the testing cycle. Furthermore, the varying lengths of the pressure pipelines used in the tests and the lack of dedicated cable reeling devices cause the pipelines to easily become tangled and knotted at the tank inlet and outlet, resulting in abnormal pressure transmission, data distortion, or equipment malfunction.

[0003] Traditional improvement methods reduce collisions by adding buffer layers or partitions, but they cannot flexibly adapt to changes in sample size; pressure pipeline management relies on manual handling, which is inefficient and unreliable. These problems lead to increased testing costs and a higher risk of test result deviations. Utility Model Content

[0004] The purpose of this utility model is to provide a high-pressure pipe receiver that integrates a winding wheel and a coiling spring mechanism to realize the dynamic winding and unwinding of the high-pressure pipe. The internal liquid channel of the pressure shaft is connected to the high-pressure pipe to ensure stable delivery of high-pressure liquid during rotation. The coiling spring mechanism automatically retracts the pipe and keeps it taut, solving the problems of pipe tangling and abnormal pressure transmission in traditional pipe systems.

[0005] This utility model is achieved through the following technical solution:

[0006] A high-voltage pipe receiver, comprising:

[0007] The bracket serves as a basic frame and has flange holes on two opposite side plates;

[0008] The winding wheel is connected to the central cavity of the bracket by the pressure shaft passing through the flange hole, and the winding wheel rotates synchronously with the pressure shaft.

[0009] The pressure shaft has a liquid channel in the middle, and the high-pressure pipe wound around the outer circumference of the winding wheel is connected to the liquid channel through the liquid injection port.

[0010] A coil spring mechanism, comprising a coil spring connected to the winding wheel and providing rotational force to the winding wheel.

[0011] In this design, a support frame is used as the basic framework to ensure stable installation of the device. The pressure shaft passes through a flange hole to position the winding wheel in the central cavity of the support, allowing the winding wheel to rotate synchronously with the pressure shaft to wind and unwind the high-pressure tube. Simultaneously, the liquid channel inside the pressure shaft is connected to the high-pressure tube, ensuring that the high-pressure liquid can still be stably transmitted to the sample while rotating. The coiling spring mechanism, through the connection between the coiling spring and the winding wheel, automatically releases the spring force after the test to drive the winding wheel to rotate back, neatly winding and retrieving the high-pressure tube, preventing the tube from tangling and maintaining a taut state. This achieves dynamic management of the high-pressure tube and pressure-sealed transmission, significantly improving the efficiency and stability of the hydrostatic test, and reducing mutual interference between samples and the risk of equipment failure.

[0012] Furthermore, the high-pressure pipe receiver also includes a ratchet and pawl mechanism, which includes a pawl and a ratchet.

[0013] The ratchet and the winding wheel are coaxially connected as one unit. One end of the pawl is rotatably connected to the side plate of the bracket through the ratchet shaft, and the other end of the pawl is always in contact with the ratchet by its own weight.

[0014] In this design, the ratchet and winding wheel are coaxially connected as one unit. Utilizing the unidirectional locking characteristic of the pawl's own weight constantly abutting against the ratchet, the winding wheel is allowed to rotate unidirectionally to release the pipe when it is pulled outwards, while simultaneously preventing the winding wheel from rotating in the opposite direction to retract. This ensures that the high-pressure pipe maintains the required length stably during the test, avoiding accidental pipe retraction due to water flow impact or spring force, thereby guaranteeing the continuity of pressure transmission and the accuracy of test data.

[0015] Furthermore, the ratchet and pawl mechanism also includes a handle and a pawl sleeve. The pawl sleeve is fixed to the side plate of the bracket. The ratchet shaft passes through the pawl sleeve and is connected to the pawl. The handle is connected to the other end of the ratchet shaft.

[0016] In this design, the pawl sleeve is fixed to the side plate of the bracket, and the ratchet shaft passes through the pawl sleeve and connects to the pawl. This enhances the stability and accuracy of the ratchet shaft rotation, reduces potential shaking and offset during use, and ensures that the pawl can accurately engage with the ratchet to effectively lock and unlock the winding wheel. The handle connected to the other end of the ratchet shaft provides the operator with a convenient control method. When it is necessary to unlock the winding wheel to allow the coil spring mechanism to retract the high-pressure tube, the operator only needs to operate the handle to easily disengage the pawl from the ratchet, release the lock on the winding wheel, and achieve automatic retraction of the high-pressure tube. When it is necessary to lock the winding wheel, the pawl can also be re-engaged with the ratchet by operating the handle to ensure that the high-pressure tube operates stably at the appropriate length.

[0017] Furthermore, the coiling spring mechanism also includes a coiling spring baffle and a coiling spring shaft;

[0018] The coil spring baffle and the coil spring shaft are both connected to the side plate of the bracket. The inner coil spring is connected to the coil spring shaft. The outer coil spring is connected to the winding wheel through the coil spring outer sleeve. The ratchet is coaxially connected to the winding wheel and rotates between the coil spring baffle and the coil spring shaft.

[0019] In this design, the coil spring baffle and coil spring shaft are fixed to the side plate of the bracket to form a support frame for the coil spring mechanism. The inner coil spring is rigidly connected to the coil spring shaft, and the outer coil spring rotates synchronously with the winding wheel through the coil spring sleeve. This allows the coil spring to store elastic force when the high-pressure pipe is pulled out and release the elastic force after unlocking to drive the winding wheel to rotate and retract the pipe. At the same time, the space between the coil spring baffle and the coil spring shaft provides guidance for the coaxial rotation of the ratchet and the winding wheel, ensuring that the spring force is evenly transmitted to the winding wheel and preventing the coil spring from axially shifting or twisting during rotation.

[0020] Furthermore, each end of the winding reel is provided with a bearing chamber that supports the pressure shaft, and the bearing chamber is coaxially connected to the bracket through the flange hole.

[0021] In this design, the bearing housing provides a stable and precise support structure for the pressure shaft, effectively reducing friction during rotation. This allows the winding wheel to rotate more smoothly and synchronously with the pressure shaft, greatly improving the flexibility and efficiency of high-pressure pipe winding and unwinding operations. Furthermore, the flange hole enables coaxial connection with the support, ensuring the positional accuracy and coaxiality of the winding wheel within the entire device. This prevents the winding wheel from wobbling or shifting during rotation, thus ensuring that the high-pressure pipe remains neat and orderly during winding and unwinding, preventing problems such as tangling and knotting, and guaranteeing the stable and reliable operation of the high-pressure pipe storage and transportation functions.

[0022] Furthermore, the high-pressure pipe receiver also includes a pressure shaft sealing assembly. One end of the pressure shaft sealing assembly is connected to the side plate of the bracket, and the other end of the pressure shaft sealing assembly forms a sealed chamber with the liquid inlet of the pressure shaft. The sealed chamber is in communication with the liquid channel.

[0023] In this design, one end of the pressure shaft sealing assembly is connected to the side plate of the bracket, and the other end forms a sealed chamber with the liquid inlet of the pressure shaft and is connected to the liquid channel. This effectively prevents high-pressure liquid from leaking at the liquid inlet of the pressure shaft. The presence of the sealed chamber provides a closed and safe environment for the transportation of high-pressure liquid. It ensures the stability of the pressure in the liquid channel, allowing the high-pressure liquid to be stably transported through the liquid channel to the high-pressure tube wound around the outer circumference of the winding wheel. This ensures the reliability and efficiency of the entire high-pressure tube receiver when transporting high-pressure liquid.

[0024] Furthermore, the pressure shaft sealing assembly includes a sealing joint and a sealing chamber;

[0025] The sealing chamber is connected to the inlet section of the pressure shaft through the middle and sleeved thereon. A sealing structure is formed between the inner wall of the sealing chamber and the outer wall of the inlet section. The sealing joint is sealed to the end of the sealing chamber near the inlet by a sealing gasket. The sealing joint and the sealing chamber form the sealing cavity at the inlet of the pressure shaft.

[0026] In this design, the central part of the sealing chamber runs through and fits over the inlet section of the pressure shaft. The sealing structure formed by its inner wall and the outer wall of the inlet section effectively prevents high-pressure liquid from leaking through the gap between them, providing a basic defense for stable liquid transmission. The sealing joint is connected to the end of the sealing chamber near the inlet via a sealing gasket, forming a sealed cavity together with the sealing chamber at the inlet of the pressure shaft. This sealed cavity ensures that the high-pressure liquid does not overflow when entering the liquid channel of the pressure shaft, maintaining pressure stability within the system and ensuring that the high-pressure pipe receiver can transport high-pressure liquid normally and efficiently.

[0027] Furthermore, the pressure shaft sealing assembly also includes a third sealing ring, a top sleeve, and a tightening spring;

[0028] A sealing groove for accommodating the third sealing ring is provided between the outer wall of the pressure shaft and the inner wall of the sealing chamber, and the top sleeve is pressed against the third sealing ring by the tightening spring.

[0029] In this design, the third sealing ring, top sleeve, and tightening spring significantly improve sealing reliability through a dynamic compensation mechanism. The third sealing ring is embedded in the sealing groove between the outer wall of the pressure shaft and the inner wall of the sealing chamber, directly undertaking the sealing function of the high-pressure liquid. Under the elastic force of the tightening spring, the top sleeve continuously applies axial pressure to the third sealing ring, ensuring that the sealing ring is always in close contact with the sealing surface, effectively compensating for the increase in sealing gap caused by wear or temperature changes, thereby maintaining long-lasting and stable sealing performance under high-pressure environments.

[0030] Furthermore, the pressure shaft sealing assembly also includes a first sealing ring, a spacer, and a second sealing ring;

[0031] The first sealing ring, the spacer, and the second sealing ring are located behind the third sealing ring and are sequentially arranged along the axial direction of the pressure axis between the outer wall of the pressure axis and the inner wall of the sealing chamber.

[0032] In this design, the arrangement of the first sealing ring, spacer, and second sealing ring significantly improves the sealing performance through a multi-stage sealing structure. The first and second sealing rings are arranged sequentially behind the third sealing ring along the pressure axis, respectively undertaking the primary and secondary sealing functions, forming a double protective barrier to effectively prevent high-pressure liquid from leaking along the gap between the pressure axis and the sealing chamber. The spacer, located between the two sealing rings, not only separates the pressure gradient to reduce the load on a single set of sealing rings, but also provides structural support to prevent the sealing rings from deforming due to axial force.

[0033] Furthermore, an opening is provided on the side wall of the bracket parallel to the axis of the pressure shaft, through which the high-pressure pipe passes.

[0034] In this design, an opening parallel to the pressure axis provides a directional path for the high-pressure pipe, ensuring that the high-pressure pipe remains straight during deployment and retraction. This reduces resistance and wear caused by pipe bending, while also preventing the high-pressure pipe from getting tangled or knotted inside the support, thus ensuring the tension and stability of the pipe during the test.

[0035] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0036] This utility model achieves automatic retraction and tension control of high-pressure pipes by linking the coiling spring mechanism of the high-pressure pipe receiver with the ratchet and pawl, thus avoiding the problem of tangling and knotting caused by manual pipe handling.

[0037] 2. The pressure shaft of this utility model integrates a liquid channel and a pressure shaft sealing assembly, which maintains stable transmission of high-pressure liquid while the winding wheel rotates, ensuring the accuracy of test data. Attached Figure Description

Detailed Implementation

[0044] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0045] Example 1

[0046] This embodiment 1 provides a high-pressure pipe receiver, such as... Figures 1-2 As shown, it includes a bracket 4, a winding wheel 7, and a coiling spring mechanism 5;

[0047] Please refer to Figure 1 As shown, the bracket 4 adopts a high-strength aluminum alloy frame, with flange holes on the opposite side plates for mounting bearing chambers 8 respectively. The cavity in the middle of the bracket 4 can accommodate the winding wheel 7 and the coil spring mechanism 5. The pressure shaft 9 passes through the flange holes on both sides of the bracket 4, and its two ends are connected to the bearing chambers 8 through bearings 23, allowing it to rotate freely. An opening is provided on the side wall of the bracket 4 parallel to the axis of the pressure shaft 9.

[0048] The winding reel 7 has a double-disc structure, with spokes connecting the wheel plates. The high-pressure tube 6 is wound around its outer circumference and exits through an opening in the side wall of the support 4, providing a directional exit path for the tube. The middle of the winding reel 7 is fixedly connected to the pressure shaft 9, allowing the winding reel 7 and the pressure shaft 9 to rotate synchronously. The coiling spring mechanism 5 includes a coiling spring 53. The outer ring of the coiling spring 53 rotates synchronously with the winding reel 7 through a coiling spring sleeve 52, while the inner ring of the coiling spring 53 is connected to the support 4. During use, the coiling spring 53 stores elasticity when the high-pressure tube 6 is pulled out and releases the elasticity after use to drive the winding reel 7 to rotate and retract the tube. This achieves dynamic deployment and retraction of the high-pressure tube.

[0049] Meanwhile, a liquid channel 91 is opened in the middle of the pressure shaft 9, and multiple liquid injection ports 92 are opened on the end face of the shaft section in the bracket 4. The number of ports can be opened according to actual needs. The liquid injection ports 92 are connected to the high-pressure pipe 6 to ensure that the high-pressure liquid can still be stably transmitted to the sample in the rotating state, thus ensuring the accuracy of the test data.

[0050] Example 2

[0051] This embodiment 2 provides a high-pressure pipe receiver based on embodiment 1, such as... Figure 1 and Figure 3 As shown, it also includes a ratchet and pawl mechanism 3, which includes a pawl 34, a ratchet 35, a handle 31, and a pawl sleeve 33. The coil spring mechanism 5 also includes a coil spring baffle 51 and a coil spring shaft 54.

[0052] Among them, such as Figure 3 As shown, the coil spring baffle 51 and the coil spring shaft 54 ​​are both connected to the side plate of the bracket 4. The inner ring of the coil spring 53 is connected to the coil spring shaft 54, and the outer ring of the coil spring 53 is connected to the winding wheel 7 through the coil spring sleeve 52. The ratchet 35 is coaxially connected to the winding wheel 7 and rotates between the coil spring baffle 51 and the coil spring shaft 54. The pawl sleeve 33 is fixed to the side plate of the bracket 4. The ratchet shaft 32 passes through the pawl sleeve 33 and is rotatably connected to the pawl 34. The free end of the pawl 34 always abuts against the ratchet 35 by its own weight. At this time, when the high-pressure pipe 6 is pulled outward, the winding wheel 7 is allowed to rotate in one direction to release the pipe, while preventing the winding wheel 7 from rotating in the opposite direction to retract, ensuring that the high-pressure pipe maintains the required length stably during the test. The handle 31 is connected to the other end of the ratchet shaft 32. When it is necessary to unlock the winding wheel 7 to allow the coil spring mechanism 5 to retract the high-pressure pipe 6, the operator only needs to operate the handle 31 to easily disengage the pawl 34 from the ratchet 35, release the lock on the winding wheel 7, and realize the automatic retraction of the high-pressure pipe 6.

[0053] Example 3

[0054] This embodiment 3 provides a high-pressure pipe receiver based on embodiment 1 or embodiment 2, such as... Figures 1-3 As shown, in order to ensure that the high-pressure liquid can be stably delivered through the liquid channel 91 to the high-pressure pipe 6 wound around the outer circumference of the winding wheel 7, a pressure shaft sealing assembly 2 is also included. One end of the pressure shaft sealing assembly 2 is connected to the side plate of the bracket 4, and the other end of the pressure shaft sealing assembly 2 forms a sealed chamber with the liquid inlet of the pressure shaft 9. The sealed chamber is connected to the liquid channel 91.

[0055] Specifically, such as Figure 2 As shown, the pressure shaft sealing assembly 2 includes a sealing joint 1 and a sealing chamber 22. The middle part of the sealing chamber 22 is through and sleeved on the liquid inlet section of the pressure shaft 9. A sealing structure is formed between the inner side wall of the sealing chamber 22 and the outer side wall of the liquid inlet section. The sealing joint 1 is sealed and connected to the end of the sealing chamber 22 near the liquid inlet through a sealing gasket 21. The sealing joint 1 and the sealing chamber 22 form the aforementioned sealing cavity at the liquid inlet of the pressure shaft 9.

[0056] The pressure shaft sealing assembly 2 also includes a third sealing ring 27, a top sleeve 28, and a tightening spring 29. A sealing groove for accommodating the third sealing ring 27 is provided between the outer wall of the pressure shaft 9 and the inner wall of the sealing chamber 22. The top sleeve 28 is tightened against the third sealing ring 27 by the tightening spring 29. The third sealing ring 27 directly undertakes the sealing function of high-pressure liquid. Under the elastic force of the tightening spring 29, the top sleeve 28 continuously applies axial pressure to the third sealing ring 27 to ensure that the sealing ring is always tightly fitted with the sealing surface, effectively compensating for the increase in sealing gap caused by wear or temperature changes.

[0057] To further improve sealing performance, the aforementioned pressure shaft sealing assembly 2 also includes a first sealing ring 24, a spacer 25, and a second sealing ring 26. The first sealing ring 24, spacer 26, and second sealing ring 26 are located behind the third sealing ring 27 and are sequentially arranged along the axial direction of the pressure shaft 9 between the outer wall of the pressure shaft 9 and the inner wall of the sealing chamber 22. The first sealing ring 24, spacer 25, and second sealing ring 26 significantly improve sealing performance through a multi-stage sealing structure. The first and second sealing rings respectively perform primary and secondary sealing functions, forming a double protective barrier to effectively prevent high-pressure liquid from leaking along the gap between the pressure shaft 9 and the sealing chamber 22.

[0058] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model.
