Description

Technical Field

[0001] The present application relates to the technical field of pipeline accessories, and in particular to a pipe clamp assembly, a counterweight mechanism and an air conditioning pipeline system. Background Art

[0002] In existing devices and equipment, pipelines or pipes are often used to realize the transmission of working media or materials. In order to adapt to the pipeline installation environment, the pipeline usually has multiple bending sections for realizing the layout along the pipeline.

[0003] In order to avoid the angle change of the pipeline in the bending section, which may cause the pipeline to deform, the angle of the pipeline in the bending section needs to be fixed. However, the existing pipe clamp blocks are usually only provided with pipe fixing holes with axes parallel or perpendicular to each other, which can only achieve the fixed layout angle between two parallel pipelines or pipelines with two ends perpendicular to each other, and cannot be applied to other complex angles. As a result, the scope of use of the pipe clamp blocks in the prior art is limited and the versatility is poor. When there are other bending angles in the pipeline, additional pipe clamp blocks with corresponding angles need to be customized, which will greatly increase the cost of pipeline accessories.

[0055] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0056] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0057] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or a posture change or a motion state change, then these directional indications also change accordingly, for example: an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." may include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative descriptors used herein are interpreted accordingly.

[0058] In order to solve the technical problems of limited use range and poor versatility of the pipe clamp blocks in the prior art, the present application provides a pipe clamp assembly, a counterweight mechanism and an air-conditioning pipe system, which can realize the relative position adjustment of the second clamping parts 4 on both sides of the main connecting part 1 by rotating the auxiliary connecting part 3 relative to the main connecting part 1, thereby realizing the clamping of pipes 8 with different bending angles and the fixing of the layout angles of the bending sections with different bending angles on the pipe 8, so that the pipe clamp assembly of the present application can be used for clamping and fixing any bending section of the pipe 8, thereby improving the use range and versatility of the pipe clamp assembly.

[0059] See also Figures 1 to 17 In a first aspect, an embodiment of the present application provides a pipe clamp assembly, comprising a main connecting member 1 and a secondary connecting member 3. One end of the main connecting member 1 is provided with a first clamping member 2, which can be used to clamp at the bending part of the bending section (i.e., the bent pipe section 82) as a positioning fulcrum between the pipe clamp assembly and the pipeline 8, such as Fig.12 , Fig.16 and Fig.17 shown.

[0060] The secondary connector 3 is movably arranged on both sides of the main connector 1, and the secondary connector 3 can rotate relative to the main connector 1, and the angle of the secondary connector 3 on both sides of the main connector 1 can be adjusted, thereby realizing the adjustment of the opening and closing degree of the pipe clamp assembly. The secondary connector 3 is provided with a second clamping member 4 at one end away from the main connector 1, which can be used to connect with the straight pipe section 81 of the pipeline 8. When the secondary connector 3 rotates relative to the main connector 1, the relative position between the second clamping members 4 on both sides of the main connector 1 also changes, so that the position of the second clamping members 4 on both sides of the pipe clamp assembly can be matched with the layout position between the bending sections, thereby realizing the clamping and fixing of two straight pipe sections 81 connected at different bending angles.

[0061] It should be noted that when there are multiple bending sections with different bending angles in the pipeline 8, multiple pipe clamp assemblies can be set one by one with the multiple bending sections. By adjusting the rotation angle of the auxiliary connecting member 3 relative to the main connecting member 1, the position of the second clamping member 4 on both sides of the pipe clamp assembly can be matched with the layout position between the bending sections, thereby achieving clamping adaptation between the pipe clamp assembly and the complex angle.

[0062] In some embodiments of this application, please refer to Figure 1 , Figure 2 and Fig.12 The pipe clamp assembly also includes an adjusting sleeve 5, in which the main connecting member 1 is inserted. The adjusting sleeve 5 can move along the length direction of the main connecting member 1. One end of the auxiliary connecting member 3 is hinged to the adjusting sleeve 5. When the adjusting sleeve 5 moves relative to the main connecting member 1, the relative position adjustment between the auxiliary connecting member 3 and the main connecting member 1 can be realized synchronously, which can improve the operation convenience of the pipe clamp assembly.

[0063] In some embodiments of this application, please refer to Figure 1 and Figure 2 At least two auxiliary connecting parts 3 are symmetrically arranged on both sides of the adjusting sleeve 5, and each auxiliary connecting part 3 is provided with a second clamping part 4 at one end away from the adjusting sleeve 5, which can realize symmetrical connection with the straight pipe sections 81 on both sides of the curved pipe section 82, avoiding uneven force on the straight pipe sections 81 on both sides of the curved pipe section 82.

[0064] It should be noted that when the size of the pipeline 8 is large or the length of the straight pipe sections 81 on both sides of the curved pipe section 82 is long, the straight pipe sections 81 can be fixed by multiple auxiliary connectors 3 and second clamping components 4 to improve the connection reliability of the pipe clamp assembly.

[0065] In some preferred embodiments of the present application, a secondary connector 3 is provided on both sides of the adjusting sleeve 5, and a second clamping member 4 is provided at one end of each secondary connector 3 away from the adjusting sleeve 5, so that the number of parts can be reduced and the structure of the pipe clamp assembly can be simplified while achieving symmetrical connection with the straight pipe sections 81 on both sides of the curved pipe section 82. Figure 1 and Figure 2 shown.

[0066] Specifically, when the auxiliary connecting parts 3 on both sides of the main connecting part 1 are symmetrically connected to the two sides of the adjusting sleeve 5, the relative positions of the two auxiliary connecting parts 3 and the main connecting part 1 can be adjusted simultaneously by moving the adjusting sleeve 5 along the length direction of the main connecting part 1, thereby realizing the clamping angle adjustment of the pipe clamp assembly. There is no need to adjust the rotation angle of the auxiliary connecting parts 3 relative to the main connecting part 1 one by one, which can improve the operation convenience of the pipe clamp assembly.

[0067] It should be noted that the movement of the adjusting sleeve 5 along the length direction of the main connecting member 1 can be achieved through the relative sliding connection between the adjusting sleeve 5 and the main connecting member 1, or through the threaded connection between the adjusting sleeve 5 and the main connecting member 1, both of which can achieve the purpose of this application.

[0068] However, when the adjustment sleeve 5 is moved along the length direction of the main connecting member 1 through a relative sliding connection, a corresponding limiting structure or damping structure is also required to fix the position of the adjustment sleeve 5 in the length direction of the main connecting member 1, which will make the structure of the main connecting member 1 complicated.

[0069] Therefore, in some preferred embodiments of the present application, please refer to Figure 1 and Figure 2 , Fig.10 and Fig.11The main connecting member 1 and the first clamping member 2 are rotatably connected, so that the main connecting member 1 can rotate relative to the first clamping member 2. The main connecting member 1 is a rod-shaped structure, and an external thread 11 is provided on the outer peripheral surface of the main connecting member 1. The adjusting sleeve 5 has an internal thread 51 matched with the external thread 11. When the main connecting member 1 rotates relative to the first clamping member 2, the adjusting sleeve 5 can move along the length direction of the main connecting member 1 (i.e., the axial direction of the external thread 11) under the cooperation of the external thread 11 and the internal thread 51. When the main connecting member 1 stops rotating, self-locking can be achieved through threaded connection, and there is no need to set an additional limiting structure on the main connecting member 1. The reliability of the pipe clamp assembly can be improved while simplifying the structure of the main connecting member 1.

[0070] As a specific embodiment of the present application, when the main connecting member 1 rotates forward, the adjusting sleeve 5 moves along Figure 1 The main connecting member 1 is moved from top to bottom in order to realize the opening of the pipe assembly; when the main connecting member 1 is reversed, the adjusting sleeve 5 moves along Figure 1 The pipe clamp assembly moves from bottom to top in order to facilitate the folding of the pipe clamp assembly.

[0071] In some embodiments of this application, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A first clamping groove 21 is provided at one end of the first clamping member 2, and a reverse hook tooth portion 12 is provided at one end of the main connecting member 1. The reverse hook tooth portion 12 is embedded in the first clamping groove 21, and the reverse hook tooth portion 12 can rotate relative to the first clamping groove 21. The reverse hook tooth portion 12 is prevented from coming out of the first clamping groove 21 without affecting the relative rotation between the main connecting member 1 and the first clamping member 2.

[0072] Specifically, the inverted hook tooth portion 12 includes a plurality of inverted hook tooth pieces 121 uniformly arranged along the circumference of the main connecting member 1, and a circumferential gap exists between two adjacent inverted hook tooth pieces 121, so that the inverted hook tooth pieces 121 are elastically deformed when inserted into the first clamping groove 21. After the inverted hook tooth piece 121 is inserted into the first clamping groove 21, it is reset under the action of elastic force, so that the inverted hook tooth piece 121 abuts against the inner wall of the first clamping groove 21, thereby preventing the inverted hook tooth portion 12 from falling out of the first clamping groove 21.

[0073] In some embodiments of this application, please refer to Figure 6 A guide structure 22 is provided at the open end of the first clamping groove 21, which can guide the multiple inverted hook teeth 121 to converge toward the center of the first clamping groove 21, so that the inverted hook tooth portion 12 can smoothly enter the first clamping groove 21, realize the connection between the inverted hook tooth portion 12 and the first clamping groove 21, and thus quickly realize the rotational connection between the main connecting member 1 and the first clamping member 2.

[0074] In some embodiments of the present application, the first clamping member 2 has a connecting tube 24, and the first clamping groove 21 and the guide structure 22 are both arranged inside the connecting tube 24. Figure 6 The first clamping member 2 can be made by an integrated molding process, which is convenient for reducing the difficulty of making the first clamping member 2 and improving the production efficiency of the first clamping member 2 .

[0075] In some embodiments of this application, please refer to Figure 1 and Figure 2 , the two ends of the secondary connector 3 are respectively provided with a first pin shaft 31 and a second pin shaft 32; the secondary connector 3 is hinged to the adjustment sleeve 5 through the first pin shaft 31, so that the secondary connector 3 and the adjustment sleeve 5 can rotate relative to each other, thereby adjusting the angle between the secondary connector 3 and the main connector 1. The secondary connector 3 is hinged to the second clip 4 through the second pin shaft 32, so that the secondary connector 3 and the second clip 4 can rotate relative to each other, so that the second clip 4 can be assembled with the straight pipe section 81 by adjusting the position of the second clip 4. The axis of the first pin shaft 31 is perpendicular to the axis of the second pin shaft 32, so that the angle adjustment of the secondary connector 3 and the position adjustment of the second clip 4 can be avoided to affect each other, so that the clamping angle formed by the pipe clamp assembly cannot be adapted to the bending angle of the pipeline 8.

[0076] For details, please refer to Figure 7 and Figure 8 The auxiliary connecting member 3 includes a connecting arm 33, and the two ends of the connecting arm 33 are respectively provided with a first hinge part 331 and a second hinge part 332, and the first hinge part 331 and the second hinge part 332 each include two oppositely arranged hinge ear plates for forming a U-shaped hinge opening.

[0077] See also Fig.10 and Fig.11 A fourth hinge portion 52 is provided on both sides of the adjustment sleeve 5, and the fourth hinge portion 52 cooperates with the first hinge portion 331 on the auxiliary connecting member 3 on its corresponding side. The fourth hinge portion 52 is inserted into the U-shaped hinge opening of the first hinge portion 331, and the first pin shaft 31 is inserted in the first hinge portion 331 and the fourth hinge portion 52, so that the connecting arm 33 of the auxiliary connecting member 3 can only rotate around the axis of the first pin shaft 31.

[0078] See also Fig. 9 The second clamping member 4 is provided with a third hinged portion 42, which is inserted into the U-shaped hinged opening of the second hinged portion 332, and the second pin shaft 32 is inserted into the second hinged portion 332 and the third hinged portion 42, so that the second clamping member 4 can only rotate around the axis of the second pin shaft 32.

[0079] In the above embodiment, if the working medium flowing in the pipeline 8 is a high-temperature medium, the first clamp 2 and the second clamp 4 are in direct contact with the outer wall of the pipeline 8 and need to have certain heat resistance. Therefore, in some embodiments of the present application, the first clamp 2 and the second clamp 4 are made of high-temperature resistant materials, which can be used to achieve a fixed bending angle of the high-temperature pipeline 8.

[0080] In some embodiments of the present application, the first clamping member 2 and the second clamping member 4 can be made of metal material or hard plastic material. Specifically, the metal material can be aluminum alloy, sheet metal and casting, etc., while the hard plastic material can be ABS (acrylonitrile-butadiene-styrene copolymer), PP (polypropylene), nylon, etc., all of which can achieve the purpose of the present application.

[0081] It should be noted that the present application can achieve close contact or unloading between the pipe clamp assembly and the pipeline 8 by rotating the main connecting piece 1, which facilitates the disassembly and assembly between the pipe clamp assembly and the pipeline 8, making the pipe clamp assembly in the present application easy to disassemble and assemble and can be reused, thereby avoiding waste of pipeline accessories.

[0082] In the above embodiment, when pipeline 8 is the refrigerant pipeline 8 of an air conditioner, the stress at the bending position of pipeline 8 may cause problems such as excessive stress and strain due to factors such as refrigerant impact and unit vibration. Pipeline 8 will produce stress fatigue if it operates in this condition for a long time, thereby causing pipeline 8 to break and leak.

[0083] In the prior art, there are methods to solve pipeline stress and strain, such as fixing with a pipe fixing block, fixing with a damping block, and fixing with a sheet metal bracket, but these methods all have limitations in use. Among them, the setting of the pipe fixing block requires that the two pipes be parallel or vertical, and other angles or single pipes are not applicable. The damping block cannot be used on high-temperature pipelines due to its low temperature resistance. The same damping block can only reduce the natural frequency of a section of pipeline 8 to a limited extent. If the stress on the pipeline 8 exceeds the standard, the thickness and weight of the damping block can only be increased, which will cause the damping block to occupy a large area and cumbersome operation. In addition, the assembly of the pipe fixing block and the damping block is relatively complicated, and they need to be fastened with wire ties. The wire ties need to be removed during disassembly, and the removed damping blocks and wire ties cannot be reused, which easily leads to waste of resources. For pipelines 8 with larger diameters, the stress reduction effect of the pipe fixing block and the damping block at the bending position of the pipeline 8 is minimal, and a stronger sheet metal bracket is needed for fixing. However, the sheet metal bracket fixing method has high requirements on the size of the space around the pipeline 8 and the position of the pipeline 8, and the sheet metal bracket needs to be connected to the chassis or other sheet metal parts with higher strength at other locations, and it cannot adapt to all pipelines 8.

[0084] In order to solve the above technical problems, the second aspect of the embodiment of the present application provides a counterweight mechanism, including the pipe clamp assembly in the above embodiment, and also including a counterweight assembly, which is arranged on the main connecting member 1. The counterweight assembly is arranged in the bending area of ​​the pipeline 8 through the pipe clamp assembly, so as to reduce the stress and strain of the pipeline 8. Fig.16 and Fig.17 shown.

[0085] Specifically, the pipe clamp assembly of the present application clamps the curved pipe section 82 and the straight pipe section 81 at the bending position of the pipe 8 to fix the bending angle. At the same time, the counterweight assembly is arranged on the main connecting member 1 to increase the weight at the bending position of the pipe 8, reduce the natural frequency of the system, reduce the vibration of the pipe 8, thereby reducing the stress and noise strain of the pipe 8, and avoiding the pipe 8 from rupture and refrigerant leakage when the stress exceeds the standard.

[0086] In some embodiments of the present application, the end of the main connecting member 1 away from the first clamping member 2 is a connecting end 13, which can be used to achieve connection with the counterweight assembly, so that the counterweight assembly is away from the bent pipe section 82, and avoid interference between the setting of the counterweight assembly and components such as the bent section of the pipeline 8 and the auxiliary connecting member 3.

[0087] In some embodiments of this application, please refer to Fig.12 , Fig.13 , Fig.14 , Fig.15 , Fig.16 and Fig.17 The weight balancing assembly includes a base 6 and a weight balancing block 7. The base 6 is connected to one end of the main connecting member 1 away from the first clamping member 2. While the weight balancing assembly is connected to the pipe clamp assembly, the adjusting sleeve 5 can also be limited to prevent the adjusting sleeve 5 from being disengaged from one end of the main connecting member 1. The weight balancing block 7 is detachably arranged on the base 6, so that the arrangement of the weight balancing block 7 can be adjusted according to the stress and strain of the pipeline 8.

[0088] In some embodiments of the present application, a connection hole 63 is provided at the center of the base 6, and a fixed connection between the base 6 and the main connecting member 1 can be achieved through interference fit or threaded connection between the connection hole 63 and the connecting end 13 of the main connecting member 1.

[0089] It should be noted that the number, size and weight of the counterweights 7 provided on the base 6 can be adjusted according to the test results of the stress detection experiment of the pipeline 8, and are not limited here.

[0090] In some embodiments of this application, please refer to Fig.13 and Fig.14The base 6 is coaxially arranged with the main connecting member 1, and a plurality of first clamping portions 61 are sequentially arranged along the circumference of the base 6. The counterweight block 7 has a second clamping portion 71 matching the first clamping portion 61. The first clamping portion 61 and the second clamping portion 71 can realize a quick connection between the counterweight block 7 and the base 6.

[0091] Specifically, the first clamping portion 61 includes a T-shaped clamping groove, and the second clamping portion 71 includes a clamping plate matching the T-shaped clamping groove. Fig.13 , Fig.14 and Fig.15 A plurality of first clamping portions 61 are evenly arranged along the outer circumference of the base 6, which can be used to realize symmetrical or eccentric installation of the counterweight block 7 in the circumferential direction of the base 6, and can be used to realize counterweight adjustment under different stress conditions.

[0092] In some embodiments of this application, please refer to Fig.14 The base 6 is also provided with a plurality of fixing parts 62, and the plurality of fixing parts 62 are arranged one by one corresponding to the plurality of first clamping parts 61. The counterweight block 7 has a connecting part 72 corresponding to the fixing part 62. The fixing part 62 and the connecting part 72 can realize a relatively fixed connection between the base 6 and the counterweight block 7 to prevent the counterweight block 7 from falling off the base 6 when it is hit by external force.

[0093] Specifically, the fixing portion 62 is a threaded hole provided at one end of the base 6 , and the connecting portion 72 is a through hole. By inserting screws into the connecting portion 72 and the fixing portion 62 in sequence, a relatively fixed connection between the counterweight 7 and the base 6 can be achieved.

[0094] In some embodiments of the present application, a plurality of first clamping portions 61 are disposed on the periphery of the base 6, a plurality of fixing portions 62 are disposed at one end of the base 6, and in order to achieve a compact connection between the counterweight 7 and the base 6, the second clamping portion 71 and the connecting portion 72 are connected in a stepped manner, such as Fig.15 When the second clamping portion 71 is inserted into the first clamping portion 61 along the axial direction of the base 6, the positioning of the fixing portion 62 and the connecting portion 72 can be achieved simultaneously. The positioning and reliable connection between the counterweight block 7 and the base 6 can be achieved.

[0095] In some embodiments of the present application, the clamping plate of the second clamping portion 71 is arranged on the end face of one end of the connecting portion 72, and the counterweight body 73 also has an arc surface arranged opposite to the clamping plate. When the clamping plate is inserted into the first clamping portion 61, the arc surface can be fitted with the outer peripheral surface of the base 6, and the end face of one end of the connecting portion 72 is L-shapedly connected to the arc surface, so that the second clamping portion 71 and the connecting portion 72 are connected in a step-like manner.

[0096] It should be noted that the counterweight body 73 of the counterweight block 7 can be a rectangular block, a strip block, a fan-shaped block or the like. In order to achieve a compact arrangement of multiple counterweight blocks 7 in the circumferential direction of the base 6 and reduce the space occupancy rate of the counterweight assembly, it is preferred to set the counterweight body 73 of the counterweight block 7 as a fan-shaped block. When multiple counterweight blocks 7 are arranged on the base 6, two adjacent counterweight blocks 7 can be tightly fitted.

[0097] The counterweight mechanism in the present application can avoid excessive stress in the pipeline 8 while fixing the bending angle of the pipeline 8. The counterweight mechanism in the present application has a compact structure and does not need to be connected and fixed to other positions. The installation space requirement of the counterweight mechanism can be reduced, and the requirement for the space size around the pipeline 8 is relatively low.

[0098] The third aspect of the embodiment of the present application provides an air conditioning pipe system, including the pipe clamp assembly in the above embodiment, so as to achieve the fixing of the bending angle in the air conditioning pipe system. Alternatively, it includes the counterweight mechanism in the above embodiment, so as to reduce the stress and strain of the air conditioning pipe system while achieving the fixing of the bending angle.

[0099] In some embodiments of this application, please refer to Fig.12 , Fig.16 and Fig.17 The air conditioning pipe system also includes a pipe 8, the bending section in the pipe 8 includes a straight pipe section 81 and a curved pipe section 82, the curved pipe section 82 is connected between two adjacent straight pipe sections 81, the first clamping member 2 is clamped on the curved pipe section 82, and the second clamping member 4 is clamped on the straight pipe sections 81 on both sides of the curved pipe section 82, which can be used to achieve the connection between the pipe clamp assembly and the pipe 8. When the first clamping member 2 cooperates with the curved pipe section 82 and the second clamping member 4 is clamped on the straight pipe section 81, the pipe clamp assembly can be tightened on the curved section of the pipe 8 by rotating the main connecting member 1, thereby achieving a stable connection between the pipe clamp assembly and the pipe 8.

[0100] In some embodiments of this application, please refer to Figure 5 , Figure 6 , Fig. 9 , Fig.12 , Fig.16 and Fig.17The first clamping member 2 is provided with a second clamping groove 23, and the cross section of the second clamping groove 23 is a U-shaped cross section, so that the second clamping groove 23 has a smaller wrapping area on the curved pipe section 82, which is convenient for the abutment and separation between the second clamping groove 23 and the curved pipe section 82. The second clamping member 4 is provided with a third clamping groove 41, and the cross section of the third clamping groove 41 is a C-shaped cross section, which can increase the wrapping area of ​​the second clamping member 4 on the straight pipe section 81, which is conducive to the stable connection between the second clamping member 4 and the straight pipe section 81. When tightening the pipe clamp assembly, the connection between the second clamping member 4 and the straight pipe section 81 can provide a good positioning effect, prevent the pipe clamp assembly from being disengaged from the pipeline 8 as a whole, and facilitate the first clamping member 2 to be smoothly pressed against the curved pipe section 82 of the pipeline 8 by rotating the main connecting member 1.

[0101] It should be noted that the first clamping member 2 and the second clamping member 4 can be provided with various specifications. When the diameter of the pipeline 8 is adjusted, the first clamping member 2 and the second clamping member 4 of corresponding sizes can be provided on the main connecting member 1 and the auxiliary connecting member 3.

[0102] See also Figures 1 to 17 In some embodiments of the present application, the method of using the above-mentioned pipe clamp assembly is as follows:

[0103] Step 1: Place the first clamping member 2 against the curved pipe section 82, rotate the main connecting member 1, and adjust the positions of the adjusting sleeve 5 and the auxiliary connecting member 3 so that the position of the auxiliary connecting member 3 is convenient for assembling the second clamping member 4 and the straight pipe section 81;

[0104] Step 2: After the second clamping parts 4 on both sides of the main connecting part 1 are connected to the straight pipe sections 81 on both sides of the curved pipe section 82, the main connecting part 1 is further rotated forward to make the first clamping part 2 press against the curved pipe section 82. At the same time, the angle between the auxiliary connecting part 3 and the main connecting part 1 changes slightly until the pipe clamp assembly is tightened on the curved section of the pipeline 8.

[0105] Step 3: When the pipe clamp assembly needs to be disassembled, reverse the main connector 1 to move the first clamping member 2 away from the curved pipe section 82 of the pipeline 8, and then separate the second clamping member 4 from the straight pipe section 81 to separate the pipe clamp assembly from the pipeline 8.

[0106] See also Figures 1 to 17 In some embodiments of the present application, the method of using the above-mentioned counterweight mechanism is as follows:

[0107] Step 1: After completing the connection between the pipe clamp assembly and the pipeline 8, the base 6 is set on the main connecting member 1;

[0108] Step 2: According to the stress condition of the pipeline 8, a counterweight block 7 is arranged on the base 6.

[0109] Specifically, the plane where the axis of the curved pipe section 82 and the axis of the straight pipe section 81 at the bending position of the pipeline 8 are located is taken as the reference plane. When the stress distribution on both sides of the reference plane is uniform and there is no over-standard situation, the balancing weight 7 may not be provided on the base 6. Fig.12 When the stress on one side of the reference plane exceeds the standard, a counterweight block 7 is arranged on the side where the stress exceeds the standard, and the counterweight block 7 is installed eccentrically to reduce the side stress on the side, as shown in FIG. Fig.16 When the stress distribution on both sides of the reference plane is uniform, but the stress on the inner side of the curved pipe section 82 (i.e., the side close to the first clamping member 2) exceeds the standard, multiple counterweights 7 can be symmetrically arranged on both sides of the reference plane to reduce the stress and strain inside the curved pipe section. Fig.17 shown.
