DETAILED DESCRIPTION

[0022] In order to make the personnel in the technical field better understand the present application scheme, the technical scheme in the present application embodiment will be clearly and completely described below in combination with the drawings in the present application embodiment. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor should belong to the scope of protection of the present application.

[0023] Please refer to Figures 1 to 2According to the utility model embodiments, an auxiliary device for replacing a high-pressure pipeline sealing ring is provided, which comprises: a first clamping block 1, a second clamping block 2, a first connecting assembly 3, a sleeve 4, and a second connecting assembly 5. The first clamping block 1 and the second clamping block 2 are both used for being installed on a pipeline. When the first clamping block 1 and the second clamping block 2 are installed on the pipeline, the first clamping block 1 and the second clamping block 2 are both protrudingly arranged on the outer wall of the pipeline. The first clamping block 1 and the second clamping block 2 are respectively located on both sides of the butt joint of the pipeline, and the first clamping block 1 and the second clamping block 2 are both fixedly connected with the pipeline. One end of the first connecting assembly 3 is clamped and matched with the first clamping block 1. The other end of the first connecting assembly 3 is adjustably connected with the sleeve 4. One end of the sleeve 4, which is away from the first connecting assembly 3, is fixedly connected with one end of the second connecting assembly 5. The other end of the second connecting assembly 5 is clamped and matched with the second clamping block 2. When the relative position between the sleeve 4 and the first connecting assembly 3 is adjusted, the distance between the first connecting assembly 3 and the second connecting assembly 5 is adjusted.

[0024] It can be seen that the auxiliary device for replacing a high-pressure pipeline sealing ring provided by the utility model comprises a first clamping block 1, a second clamping block 2, a first connecting assembly 3, a sleeve 4, and a second connecting assembly 5. The first clamping block 1 and the second clamping block 2 are both used for being installed on a pipeline. When the first clamping block 1 and the second clamping block 2 are installed on the pipeline, the first clamping block 1 and the second clamping block 2 are both protrudingly arranged on the outer wall of the pipeline. The first clamping block 1 and the second clamping block 2 are respectively located on both sides of the butt joint of the pipeline, and the first clamping block 1 and the second clamping block 2 are both fixedly connected with the pipeline. At the same time, one end of the first connecting assembly 3 is clamped and matched with the first clamping block 1. The other end of the first connecting assembly 3 is adjustably connected with the sleeve 4. One end of the sleeve 4, which is away from the first connecting assembly 3, is fixedly connected with one end of the second connecting assembly 5. The other end of the second connecting assembly 5 is clamped and matched with the second clamping block 2. Then, when the relative position between the sleeve 4 and the first connecting assembly 3 is adjusted, the distance between the first connecting assembly 3 and the second connecting assembly 5 is adjusted, so as to adjust the state of the butt joint of the pipeline. When the butt joint of the pipeline needs to be butt-jointed, the sleeve 4 moves towards the first connecting assembly 3 relative to the first connecting assembly 3, so that the distance between the first connecting assembly 3 and the second connecting assembly 5 becomes smaller, thereby reducing the gap of the butt joint of the pipeline, so as to complete the butt joint of the butt joint of the pipeline.

[0025] Therefore, the automatic adjustment of the pipe butt joint is realized by the first connecting assembly 3, the sleeve 4 and the second connecting assembly 5, without relying on manual alignment, reducing the complex alignment steps and time. Moreover, since the first clamping block 1 and the second clamping block 2 are respectively fixed on both sides of the pipe butt joint, and are relatively fixedly connected with the pipe, the stability during each adjustment is ensured, and the error caused by inconsistent manual operation is avoided. The positionally adjustable connection between the sleeve 4 and the first connecting assembly 3 allows fine tuning, ensuring that the gap of the pipe butt joint is minimized, thereby realizing high-precision butt joint. At the same time, the butt joint mode of the mechanical structure reduces the risk of misoperation caused by improper or fatigue manual operation, improving the safety and reliability of the entire system. Precise butt joint ensures effective installation of the sealing ring, reduces the possibility of leakage at the pipe connection, and enhances the sealing performance of the system. In addition, through precise butt joint and sealing, equipment damage caused by poor sealing is reduced, prolonging the service life of the equipment. The auxiliary device has simple structure and convenient operation, which can effectively reduce the investment of construction personnel and construction process, simplify the construction link, save construction time, improve work efficiency, and reduce labor intensity. Effectively solve the technical problems in the prior art that after replacing the high-pressure pipe sealing ring, the pipe still needs to be manually butt jointed, resulting in low efficiency and poor safety.

[0026] Further, when the first clamping block 1 and the second clamping block 2 are installed on the pipe, the first clamping block 1 and the second clamping block 2 are located on the same side of the pipe, and the first clamping block 1 and the second clamping block 2 are arranged in parallel.

[0027] Preferably, when the first clamping block 1 and the second clamping block 2 are installed on the pipe, the bottom end of the first clamping block 1 and the bottom end of the second clamping block 2 are on the same straight line.

[0028] Specifically, as shown in Figure 1 and Figure 2As shown, the first connecting assembly 3 includes a first connecting rod 31, which is inserted into the sleeve 4 at an end away from the first clamping block 1, and the first connecting rod 31 is threadedly connected with the sleeve 4. The auxiliary device further includes a ratchet assembly 6, the ratchet 61 of which is sleeved on the sleeve 4, and the ratchet 61 of the ratchet assembly 6 is fixedly connected with the sleeve 4, so as to drive the sleeve 4 to move along the extension direction of the first connecting rod 31 through the ratchet 61 of the ratchet assembly 6, thereby adjusting the relative position between the sleeve 4 and the first connecting assembly 3. With such a structure, the relative position between the first connecting rod 31 and the sleeve 4 can be finely adjusted through the threaded connection between the first connecting rod 31 and the sleeve 4. Each rotation of a thread will cause a slight change in distance, thereby achieving precise control of the gap at the pipe butt joint. Moreover, threaded connection has certain self-locking characteristics, and once adjusted in place, it is not easy to loosen due to external vibration or other factors. This ensures that the state of the pipe butt joint can remain stable in a high-pressure environment and will not displace unexpectedly. At the same time, the ratchet 61 of the ratchet assembly 6 is sleeved on the sleeve 4 and fixedly connected therewith, and through the rotation of the ratchet 61 of the ratchet assembly 6, one-way movement can be achieved. Thus, through each rotation of the ratchet, the sleeve 4 can be accurately moved a small distance along the extension direction of the first connecting rod 31, further improving the accuracy of adjustment. Moreover, the ratchet assembly 6 not only provides the function of one-way movement, but also can automatically lock the current position after each operation, preventing reverse movement. This design enhances the reliability and safety of the system. Moreover, through rapid rotation of the ratchet assembly 6, the position of the sleeve 4 can be quickly adjusted, shortening the time for each adjustment and improving overall work efficiency. In addition, through the design of the ratchet assembly 6 and the threaded connection, the operator only needs to rotate the ratchet to complete the precise adjustment, greatly simplifying the operation process and reducing labor intensity and time cost.

[0029] Further, as Figure 2As shown, the ratchet wheel 61 is provided with a mounting hole 610 coaxial with the ratchet wheel 61, and the mounting hole 610 is internally threaded; the outer wall of the sleeve 4 is provided with an external thread matched with the internal thread, so that the ratchet wheel 61 and the sleeve 4 are fixedly connected relative to each other through the internal thread and the external thread. With such a structure, the ratchet wheel 61 and the sleeve 4 are mechanically and firmly connected through the cooperation of the internal thread and the external thread. The threaded connection has high tensile strength and torsional strength, ensuring that the ratchet wheel 61 will not loosen or fall off in a high-pressure or vibration environment. The coaxial arrangement of the mounting hole 610 and the ratchet wheel 61 ensures that the ratchet wheel 61 can be accurately sleeved on the sleeve 4 during installation, avoiding eccentricity or asymmetry. This precise alignment ensures smooth operation of the ratchet wheel assembly 6 during the entire operation process. At the same time, the threaded connection allows quick disassembly and assembly between the ratchet wheel 61 and the sleeve 4, facilitating maintenance or replacement of parts when needed. Disassembly and reinstallation can be completed by simply rotating, without the need for complex tools or steps.

[0030] Further, as shown in Figure 2 the ratchet wheel assembly 6 further comprises a protective sleeve 62, a handle 63, a pawl 64, and a first spring 65. The protective sleeve 62 is internally provided with a mounting cavity, and the ratchet wheel 61 is arranged in the mounting cavity. The handle 63 is connected with the protective sleeve 62, and a recess is formed in the end face of the handle 63 close to the protective sleeve 62, the recess being in communication with the mounting cavity. The pawl 64 is engaged with the ratchet wheel 61, and at least part of the pawl 64 is located in the recess. The first spring 65 is installed in the recess, one end of the first spring 65 abutting against the inner wall of the recess, and the other end of the first spring 65 being connected with the pawl 64.

[0031] Optionally, when the handle 63 of the ratchet wheel assembly 6 is rotated in one direction to engage the pawl 64 with the ratchet wheel 61, the sleeve 4 is rotated by the ratchet wheel 61, and then the sleeve 4 is moved along the extension direction of the first connecting rod 31 towards the first clamping block 1, so as to adjust the relative position between the sleeve 4 and the first connecting assembly 3, so that the distance between the first connecting assembly 3 and the second connecting assembly 5 becomes smaller, thereby reducing the gap at the butt joint of the pipeline, so as to complete the butt joint of the pipeline. When the handle 63 of the ratchet wheel assembly 6 is pulled in the opposite direction, the ratchet wheel 61 pushes the pawl 64 to rotate, so that the first spring 65 is compressed, the pawl 64 is separated from the ratchet wheel 61, and the handle 63 is rotated without rotating the ratchet wheel 61.

[0032] Preferably, the ratchet wheel assembly 6 is a one-way wrench.

[0033] Optionally, when the sealing ring at the pipe joint needs to be replaced, a tension structure can be formed between the first connecting assembly 3 and the second connecting assembly 5 through the ratchet assembly 6. This structure can exert axial limiting (prevent the steel pipe from moving in the length direction) and radial limiting (prevent the steel pipe from moving in the transverse direction) on the steel pipe. After the user disassembles the connecting device on the two adjacent steel pipes (i.e., the connecting device at the pipe joint), the two steel pipes can still maintain the port fitting posture, thereby preventing misalignment or misalignment of the connecting position.

[0034] Specifically, as shown in Figure 1 The first connecting assembly 3 includes a first connecting rod 31 and a first clamping hook 32. The first connecting rod 31 is inserted into the sleeve 4 at one end away from the first clamping block 1, and the first connecting rod 31 is threadedly connected with the sleeve 4. The first clamping hook 32 is connected with the first connecting rod 31 at an end away from the sleeve 4, and the first clamping hook 32 is clamped with the first clamping block 1. With such a structure, the clamping cooperation between the first clamping hook 32 and the first clamping block 1 allows the first connecting assembly 3 to be quickly installed and disassembled, facilitating maintenance or replacement of components by the operator. The clamping hook design ensures firm connection between the first connecting assembly 3 and the first clamping block 1, preventing loosening due to external forces and improving the reliability of the system.

[0035] Further, the first connecting rod 31 and the first clamping hook 32 are connected through a first connecting ring 33.

[0036] Specifically, the first clamping hook 32 includes a first clamping hook body 321 and an insertion portion protruding from the inner wall of the first clamping hook body 321. The bottom of the first clamping block 1 is provided with an insertion hole matched with the insertion portion. When the first clamping hook body 321 is clamped in the first clamping block 1, the insertion portion is inserted into the insertion hole. With such a structure, inserting the insertion portion into the insertion hole further enhances the firmness of the connection, ensuring that the first clamping hook 32 will not easily loosen even under vibration or external force. The insertion of the insertion portion into the insertion hole further enhances the firmness of the connection, ensuring that the first clamping hook 32 will not easily loosen even under vibration or external force. The cooperation of the insertion portion and the insertion hole ensures that the first clamping hook 32 and the first clamping block 1 can be accurately aligned during installation, avoiding eccentricity or asymmetry. This accurate alignment ensures smooth operation of the entire auxiliary device during operation.

[0037] Optionally, the insertion portion protruding from the inner wall of the first clamping hook body 321 can be understood as the insertion portion protruding from the inner surface of the opening portion of the first clamping hook body 321, and the insertion portion is located on the bottom wall inside the opening portion of the first clamping hook body 321.

[0038] Further, an installation groove is formed on the inner wall of the first hook body 321, and the insertion part is telescopically arranged in the installation groove. Meanwhile, a second spring is installed in the installation groove, and the second spring extends along the extension direction of the installation groove. The two ends of the second spring respectively abut against the bottom wall of the installation groove and the insertion part, so that the insertion part is telescopically arranged in the installation groove by the second spring.

[0039] Optionally, when it is necessary to insert the insertion part into the insertion hole, first, a certain external force is applied to compress the second spring, so that the insertion part is completely retracted into the installation groove; then the first hook body 321 is clamped on the first clamping block 1; when the first hook body 321 is correctly clamped, the insertion part automatically extends under the restoring force of the second spring and is inserted into the insertion hole of the first clamping block 1, forming a firm locking state. When it is necessary to remove the insertion part from the insertion hole, the first hook body 321 can be separated from the first clamping block 1.

[0040] Specifically, as shown in Figure 1 The second connecting assembly 5 includes a second connecting rod 51 and a second hook 52. The second connecting rod 51 is fixedly connected to the sleeve 4 at an end away from the second clamping block 2. The second hook 52 is connected to the second connecting rod 51 at an end away from the sleeve 4, and is clamped and matched with the second clamping block 2. The second clamping block 2 is provided with a limiting groove. When the second hook 52 is clamped and matched with the second clamping block 2, at least part of the second hook 52 is located in the limiting groove to limit the second hook 52 by the limiting groove. With such a structure, the part of the second hook 52 is embedded in the limiting groove, which increases the additional locking mechanism and enhances the firmness and stability of the connection. The design of the limiting groove makes the second hook 52 not easy to loosen when subjected to external force or vibration, improving the stability and safety of the system. The existence of the limiting groove ensures that the second hook 52 and the second clamping block 2 can be accurately aligned during installation, avoiding eccentric or asymmetric situations. Such accurate alignment ensures the smooth operation of the entire auxiliary device during operation.

[0041] Further, as shown in Figure 1 The second connecting rod 51 and the second hook 52 are connected by a second connecting ring 53.

[0042] Further, the second connecting rod 51 is threadedly connected to the sleeve 4 at an end away from the second clamping block 2.

[0043] Specifically, as shown in Figure 1As shown, the auxiliary device further comprises: a first fixing sleeve 7 and a second fixing sleeve 8, which are respectively used to be sleeved on the pipeline, and are respectively located on both sides of the pipeline connection part, and are relatively fixedly connected with the pipeline; the first clamping block 1 is protrudingly arranged on the outer wall of the first fixing sleeve 7, and is fixedly connected with the first fixing sleeve 7; the second clamping block 2 is protrudingly arranged on the outer wall of the second fixing sleeve 8, and is fixedly connected with the second fixing sleeve 8. With such a structure, the first fixing sleeve 7 and the second fixing sleeve 8 are respectively sleeved on the pipeline and are relatively fixedly connected with the pipeline, providing multiple fixing points and enhancing the structural stability of the entire auxiliary device.

[0044] Further, the first fixing sleeve 7 is integrally formed with the first clamping block 1. The second fixing sleeve 8 is integrally formed with the second clamping block 2.

[0045] Specifically, the first fixing sleeve 7 comprises: a first pipe sleeve 71 and a first fastener 72, the first pipe sleeve 71 has a first adjusting end 711 and a second adjusting end 712, the first adjusting end 711 and the second adjusting end 712 are oppositely arranged, the first pipe sleeve 71 has an initial state and a locked state, when the first pipe sleeve 71 is in the initial state, the first adjusting end 711 and the second adjusting end 712 have an initial gap to sleeve the first fixing sleeve 7 on the pipeline; when the first pipe sleeve 71 is in the locked state, the first fastener 72 is connected with the first adjusting end 711 and the second adjusting end 712 respectively, so that the first adjusting end 711 and the second adjusting end 712 are tightly fitted by the first fastener 72; the second fixing sleeve 8 comprises: a second pipe sleeve 81 and a second fastener 82, the second pipe sleeve 81 has a third adjusting end 811 and a fourth adjusting end 812, the third adjusting end 811 and the fourth adjusting end 812 are oppositely arranged, the second pipe sleeve 81 has an initial state and a locked state, when the second pipe sleeve 81 is in the initial state, the third adjusting end 811 and the fourth adjusting end 812 have an initial gap to sleeve the second fixing sleeve 8 on the pipeline; when the second pipe sleeve 81 is in the locked state, the second fastener 82 is connected with the third adjusting end 811 and the fourth adjusting end 812 respectively, so that the third adjusting end 811 and the fourth adjusting end 812 are tightly fitted by the second fastener 82. With such a structure, the initial gap in the initial state allows the first fixing sleeve 7 and the second fixing sleeve 8 to be easily sleeved on the pipeline, while the tight fitting in the locked state ensures that they can be firmly fixed on the pipeline, preventing loosening or displacement. The design of the fastener provides an additional locking mechanism, ensuring that even under vibration or external force, the fixing sleeve will not easily slide or fall off, improving the stability and safety of the system. Moreover, the initial gap in the initial state allows the fixing sleeve to be quickly sleeved on the pipeline, while the fastener design in the locked state allows the fixing sleeve to be quickly locked, reducing the complex alignment steps and time cost.

[0046] Optionally, when the first sleeve 71 is in the initial state, there is an initial gap between the first adjusting end 711 and the second adjusting end 712, allowing the first fixing sleeve 7 to be easily sleeved on the pipeline. When it is necessary to fix the first fixing sleeve 7, the first adjusting end 711 and the second adjusting end 712 are connected by the first fastener 72 to make them fit closely, thereby firmly fixing the first fixing sleeve 7 on the pipeline. The first fastener 72 (such as a bolt, a nut, or other types of fastening devices) is used to make the first adjusting end 711 and the second adjusting end 712 fit closely, ensuring that the first fixing sleeve 7 will not loosen in the locked state. Similarly, the sleeving and locking of the second fixing sleeve 8 are consistent with those of the first fixing sleeve 7, and will not be described here.

[0047] Preferably, the first fastener 72 is a first bolt, and the second fastener 82 is a second bolt.

[0048] Further, the inner wall of the first sleeve 71 is embedded with a first elastic member, and when the first sleeve 71 is in the locked state, the first elastic member fits the outer wall of the pipeline; the inner wall of the second sleeve 81 is embedded with a second elastic member, and when the second sleeve 81 is in the locked state, the second elastic member fits the outer wall of the pipeline. With such a structure, the elastic member will generate a restoring force when it is compressed or deformed, and this restoring force makes the elastic member tightly fit the outer wall of the pipeline, providing additional friction and sealing effect, so that the first fixing sleeve 7 and the second fixing sleeve 8 can more closely fit the outer wall of the pipeline in the locked state, further enhancing the firmness and stability of the fixation. The elastic member provides a continuous compression force, ensuring that the fixing sleeve will not loosen even under vibration or external force, improving the stability and safety of the system. Moreover, the elastic member can provide a buffer between the sleeve and the pipeline, reducing the wear caused by direct metal contact and prolonging the service life.

[0049] Optionally, the first elastic member and the second elastic member are both a layer of elastic material with high friction coefficient (such as rubber, polyurethane).

[0050] Optionally, the specific steps of installing the auxiliary device on the pipeline are as follows:

[0051] When the sealing ring at the joint of the pipeline needs to be replaced, first, the first fixing sleeve 7 and the second fixing sleeve 8 are installed on both sides of the joint of the pipeline, so that the first clamping block 1 and the second clamping block 2 are both protruding from the pipeline and located on the same side of the pipeline. Then, the first clamping hook 32 is clamped on the first clamping block 1, and the second clamping hook 52 is clamped on the second clamping block 2. Then, the end of the first connecting rod 31 away from the first clamping hook 32 is connected with one end of the sleeve 4 provided with the ratchet assembly 6, and the other end of the sleeve 4 provided with the ratchet assembly 6 is connected with the first end of the second connecting rod 51 away from the second clamping hook 52. Finally, the ratchet assembly 6 adjusts the relative distance between the first connecting assembly 3 and the second connecting assembly 5, so as to complete the replacement of the sealing ring and the joint of the pipeline.
