Description

Technical Field

[0001] This utility model relates to, but is not limited to, the field of pipeline maintenance technology, and in particular to a pipeline emergency repair support device. Background Technology

[0002] Pipeline maintenance is an essential and indispensable part of ensuring the normal operation of transportation pipelines and their equipment, encompassing two main categories: routine maintenance and emergency repairs. In routine maintenance, pipeline systems require regular inspection and upkeep to prevent potential failures; while in emergency repair scenarios, quickly and effectively supporting damaged pipelines to prevent further damage or safety accidents is particularly crucial.

[0003] However, existing pipe support devices, especially those fixing rings used for emergency repairs, generally suffer from fixed dimensions and poor adaptability. Faced with pipes of different diameters and shapes, these fixing rings often fail to ensure that all support surfaces fit tightly against the lower end of the pipe. Insufficient support not only reduces the stability of the support and increases the risk during emergency repairs, but may also lead to damage to the pipe or the support device itself due to uneven stress. Utility Model Content

[0004] The following is an overview of the subject matter described in detail herein. This overview is not intended to limit the scope of the claims. This invention aims to at least solve one of the technical problems existing in the prior art. To this end, embodiments of this invention provide a pipeline emergency repair support device capable of flexibly adapting to and stably supporting pipelines of different sizes and shapes.

[0005] This utility model provides a pipeline emergency repair support device, including: a support base; a hydraulic groove disposed within the support base and filled with hydraulic oil; and a balance support assembly passing through the hydraulic groove. The balance support assembly includes a telescopic groove, a telescopic plate, a hydraulic rod, a telescopic spring, a support rod, a support plate, and a contact pad. The telescopic groove is disposed on the upper inner wall of the hydraulic groove. The telescopic plate is slidably connected within the telescopic groove. The hydraulic rod is fixedly connected to the lower end of the telescopic plate. The telescopic spring is fixedly connected to the inner wall of the telescopic groove and the lower end of the telescopic plate. The support rod is fixedly connected to the upper end of the telescopic plate. The support plate is fixedly connected to the upper end of the support rod. The contact pad is fixedly connected to the upper end of the support plate.

[0006] According to some embodiments of the present invention, the support base is provided with a pressure relief assembly, which includes a pressure relief groove, a connecting groove, a limiting groove, and a pressure relief block. The pressure relief groove is disposed on the upper inner wall of the oil pressure groove, the connecting groove is disposed on the inner wall of the pressure relief groove, the limiting groove is opened at the upper end of the support base, and the pressure relief block is slidably connected in the pressure relief groove.

[0007] According to some embodiments of this utility model, a connecting block is fixedly connected to the upper end of each pressure relief block, the connecting block is slidably connected to the connecting groove, and a limit block is fixedly connected to the upper end of each connecting block, the limit block is slidably connected to the limit groove.

[0008] According to some embodiments of this utility model, ventilation holes are provided on the inner circumferential wall of the connecting groove and the upper end of the telescopic plate.

[0009] According to some embodiments of the present invention, a first sealing ring and a second sealing ring are fixedly connected to the upper inner wall of the hydraulic groove, the first sealing ring being located at the lower end of the telescopic groove, and the second sealing ring being located at the lower end of the pressure relief groove.

[0010] According to some embodiments of the present invention, the first sealing ring is sleeved on the outer surface of the hydraulic rod, and the second sealing ring is sleeved on the outer surface of the pressure relief block.

[0011] According to some embodiments of the present invention, an upper clamping plate is fixedly connected to the inner circumferential wall of the telescopic groove, and the upper clamping plate is sleeved on the outer circumferential surface of the support rod.

[0012] According to some embodiments of the present invention, a plurality of support sleeves are fixedly connected to the upper end of the support base, the support sleeves are sleeved on the outer circumferential surface of the support rod, and a plurality of vertical support frames are fixedly connected to the circumferential surface of the support sleeves.

[0013] According to some embodiments of the present invention, the upper end face of the upper card plate abuts against the lower end face of the support sleeve.

[0014] According to some embodiments of the present invention, the lower end of the support base is provided with multiple threaded holes.

[0015] The pipeline emergency repair support device of this utility model has at least the following beneficial effects:

[0016] 1. With its built-in hydraulic groove and balance support assembly, it can flexibly adapt to pipes of different diameters and shapes. The hydraulic oil in the hydraulic groove and the elasticity of the telescopic spring allow the balance support assembly to automatically adjust the position of the telescopic plate and support plate according to the actual size of the pipe, ensuring that the contact pad fits tightly against the lower end of the pipe and provides stable support.

[0017] 2. Because the contact pad fits tightly against the pipe, the support device significantly increases the contact area of ​​the support surface, thereby improving the stability of the support. This helps reduce the risk of pipe shaking or damage caused by uneven stress during emergency repairs, ensuring the smooth progress of the repair work.

[0018] 3. Traditional pipe support devices often require replacing different sizes of fixing rings when dealing with pipes of different dimensions, which is cumbersome and time-consuming. This support device, however, allows for simple hydraulic adjustment to change the support surface, greatly simplifying the operation and improving emergency repair efficiency.

[0030] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0031] Reference Figures 1 to 4The pipeline emergency repair support device provided by this utility model includes: a support base 1; a hydraulic groove 2, which is located inside the support base 1 and can be filled with hydraulic oil; and a balance support assembly, which can be configured in multiple sets, and each set of balance support assemblies specifically includes the following structures: a telescopic groove 3, which is formed on the upper inner wall of the hydraulic groove 2; a telescopic plate 4, which is slidably connected to the telescopic groove 3, that is, it can slide smoothly within the telescopic groove 3; a hydraulic rod 5, which is fixedly connected to the lower end of the telescopic plate 4; a telescopic spring 6, whose two ends are respectively fixedly connected to the inner wall of the telescopic groove 3 and the lower end of the telescopic plate 4, which can play a role in buffering and resetting; a support rod 7, which is fixedly connected to the upper end of the telescopic plate 4; a support plate 8, which is fixedly connected to the upper end of the support rod 7; and a contact pad 9, which is fixedly connected to the upper end of the support plate 8, which can be used to directly contact the pipeline and provide support. This support device can flexibly adapt to and stably support pipelines of different sizes and shapes. Specifically, by introducing core structures such as the hydraulic groove 2 and the balance support assembly, this device can automatically adjust the position and size of each support surface according to the actual size and shape of the pipeline. This automatic adjustment mechanism ensures that all support surfaces fit tightly against the lower end of the pipeline, thereby providing stable and reliable support.

[0032] In some embodiments of this utility model, this device is typically placed at the top of a jack during pipeline repair work. The hydraulic groove 2 can be pre-filled with hydraulic oil. The upper part of the hydraulic rod 5, connected to the telescopic plate 4, is located within the telescopic groove 3, while the lower part extends into the hydraulic groove 2. The elastic force of the telescopic spring 6 abuts against the telescopic plate 4, ensuring that the telescopic plate 4 remains at the uppermost position of the telescopic groove 3. The support plate 8 supports the contact pad 9. During pipeline repair, the jack is lifted, which in turn lifts this device. During the lifting process, the contact pad 9 comes into contact with the lower end of the pipeline. As the jack continues to lift, the contact pad 9, which initially contacts the pipeline, can compress the lower end of the hydraulic rod 5, causing it to slide into the hydraulic groove 2 and compress the telescopic spring 6. It is worth noting that the sliding of the hydraulic rod 5 into the hydraulic groove 2 may cause the oil pressure within the hydraulic groove 2 to rise; therefore, a pressure relief assembly can be used to maintain the oil pressure balance within the hydraulic groove 2. As the support base 1 continues to move upward, the contact pads 9 that are in contact with the lower end of the pipe can stop moving, while the contact pads 9 that are not in contact with the pipe can continue to move upward until they contact the pipe. When all the contact pads 9 are in contact with the pipe, the pressure relief assembly reaches its maximum pressure and no longer releases pressure to the hydraulic oil in the hydraulic groove 2. At this point, the hydraulic rods 5 can no longer slide into the hydraulic groove 2, thus fixing the positions of all the hydraulic rods 5 and contact pads 9. In this way, multiple support plates 8 and contact pads 9 together provide support for the lower end of the pipe. It is worth noting that during the lifting process, this device uses the principle of hydraulic pressure to give multiple contact pads 9 a certain degree of flexibility. When encountering pipes with irregular outer surfaces, the multiple contact pads 9 can extend or retract downward by adjusting the hydraulic pressure to ensure that when the device is in a fixed position, all contact pads 9 can fully contact the lower end of the pipe. This design allows this device to effectively provide emergency support for pipes of different shapes.

[0033] In some embodiments of this utility model, such as Figures 1 to 4As shown, each side of the support base 1 of this device is equipped with a set of pressure relief components. Each set of pressure relief components specifically includes a pressure relief groove 10, a connecting groove 11, a limiting slot 12, and a sliding pressure relief block 13. The pressure relief groove 10 is formed on the upper inner wall of the hydraulic groove 2, and the connecting groove 11 is further formed on the upper inner wall of the pressure relief groove 10. The limiting slot 12 is formed at the upper end of the support base 1. The pressure relief block 13 can be slidably connected in the pressure relief groove 10, playing a key role in hydraulic pressure regulation. In actual use, when the device moves upward with the lifting of the jack, the contact pad 9 that first contacts the lower end of the pipe will be squeezed. This squeezing action may cause the hydraulic pressure in the hydraulic groove 2 to rise. The increased hydraulic pressure can then push the pressure relief block 13 to slide upward in the pressure relief groove 10. This process effectively balances the hydraulic pressure in the hydraulic groove 2, ensuring that the remaining contact pads 9 can continue to move smoothly downward until they contact the pipe. As the device continues to rise, when a certain height is reached, the pressure relief block 13 may slide to the top of the pressure relief groove 10. At this point, the pressure relief block 13 can no longer further relieve the oil pressure in the oil pressure groove 2. At this time, the high oil pressure accumulated in the oil pressure groove 2 can generate an upward thrust on multiple oil pressure rods 5. These oil pressure rods 5 can then transmit the force to the contact pad 9 through the telescopic plate 4 and the support plate 8, thereby providing stable and effective support for the lower end of the pipeline.

[0034] In some embodiments of this utility model, such as Figures 1 to 4 As shown, each of the two pressure relief blocks 13 is securely connected to a connecting block 14 at its upper end, and both connecting blocks 14 can slide within their respective connecting grooves 11. Simultaneously, each of the two connecting blocks 14 is also fixedly connected to a limiting block 15 at its upper end, and these limiting blocks 15 can slide within their respective limiting grooves 12. Specifically, the limiting blocks 15 are securely mounted on the upper end of the pressure relief block 13 via the connecting blocks 14. When the device is not in contact with the pipeline, the previously compressed telescopic spring 6 can rebound, pushing the telescopic plate 4 back to its original position. At this time, the oil pressure in the oil pressure groove 2 will decrease accordingly, and the pressure relief block 13 can fall back to its original position. During this process, the limiting blocks 15 can be locked onto the lower inner wall of the limiting groove 12 by the limiting action of the connecting groove 11, thereby effectively supporting the pressure relief block 13 and ensuring its stability.

[0035] In some embodiments of this invention, vent holes 16 can be provided on the inner circumferential wall of the connecting groove 11 and the upper ends of the multiple telescopic plates 4. The main function of these vent holes 16 is to allow air to pass through, ensuring that the air pressure inside the pressure relief groove 10 and the telescopic groove 3 can be released in a balanced manner through the vent holes 16 during the rising of the pressure relief block 13 and the falling of the telescopic plates 4, thereby avoiding changes in air pressure. This design can effectively prevent unnecessary high-pressure back thrust caused by changes in air pressure when the telescopic plates 4 and the pressure relief block 13 move, ensuring the stability and reliability of the device operation.

[0036] In some embodiments of this invention, multiple sealing rings 17 are fixedly connected to the upper inner wall of the hydraulic groove 2. These sealing rings 17 can be tightly fitted onto the outer circumferential surfaces of the multiple hydraulic rods 5 and the two pressure relief blocks 13, playing a crucial sealing role. Specifically, the sealing rings 17 are arranged on the lower side of the pressure relief groove 10 and the lower side of the telescopic groove 3, tightly wrapping the outer surfaces of the hydraulic rods 5 and the pressure relief blocks 13, to isolate the hydraulic oil, ensuring that the hydraulic oil can be firmly sealed inside the hydraulic groove 2 through the tight fit of the sealing rings 17, preventing any leakage.

[0037] In some embodiments of this utility model, upper clamping plates 21 are securely installed on the inner circumferential walls of multiple telescopic grooves 3. These upper clamping plates 21 can be sleeved on the outer circumferential surface of the corresponding support rods 7, and can play a limiting role. Specifically, the upper clamping plates 21 are set in the upper region of the inner wall of the telescopic groove 3, and their main function is to limit the vertical movement height of the telescopic plate 4. When the device is repaired and restored to normal operation, the telescopic spring 6 can use its elastic potential energy to rebound and push the telescopic plate 4 to move back to the initial position until the upper edge of the telescopic plate 4 is firmly clamped by the upper clamping plates 21, thereby ensuring that the telescopic plate 4 can accurately reset and remain stable.

[0038] In some embodiments of this utility model, a plurality of support sleeves 18 are fixedly connected to the upper end of the support base 1. These support sleeves 18 can be fitted onto the outer circumferential surface of the corresponding support rod 7 to provide support. Specifically, the support sleeves 18 are designed to enhance the structural strength of the support rod 7 and prevent it from bending due to lateral thrust when supporting the pipeline. In addition, a plurality of vertical support frames 19 are fixed to the circumferential surface of each support sleeve 18. These vertical support frames 19 are located outside the support sleeves 18, and they work together with the support sleeves 18 to reinforce the support rod 7 in all directions, thereby making the device more stable and reliable when supporting the pipeline and able to withstand greater external forces and pressures.

[0039] In some embodiments of this invention, the lower end of the support base 1 is provided with multiple threaded holes 20. These threaded holes 20 can be evenly distributed around the support base 1, providing a secure connection between the device and the jack. Specifically, by utilizing the tight fit between the threaded holes 20 and screws, the device can be easily fixed to the jack. When the jack performs a stretching operation, the device will rise accordingly, thereby providing emergency and effective support for the pipeline.
