Finally, the hand chain hoist, slings and other equipment are removed to facilitate the next assembly operation. However, the existing entire assembly operation is relatively complicated, and most of the correction and alignment processes are completed manually. Not only is the operation intensity high, the construction efficiency is low, and safety accidents are very likely to occur, but also the accuracy of the correction is low. During the alignment process, the ends of the docked water pipelines are often damaged due to hard collisions, which ultimately affects the sealing of the water pipeline joints.

DETAILED DESCRIPTION

[0018] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0019] The present invention discloses a precise positioning and plugging tool for a large-diameter water pipeline, such as Figure 1-15As shown, it includes a plurality of pipeline posture correction devices, which are arranged at intervals along the length direction of the water pipeline 300. Each pipeline posture correction device includes two single-side correction units 100, which are symmetrically arranged on both sides of the water pipeline 300, and the water pipeline 300 is clamped between the two single-side correction units 100. Each single-side correction unit 100 is connected to a step-by-step propulsion unit 200, and the function of the step-by-step propulsion unit 200 is to propel the single-side correction unit 100 to move step by step along the length direction of the water pipeline 300. The working principle and advantages of the present invention are as follows: in the process of assembling the water pipeline 300, first, a sling is used to bind the outside of the water pipeline 300, and the crane lifts the water pipeline 300 to the top of the installation position through the sling; at the same time, multiple pipeline posture correction devices are placed at pre-installed positions along the water pipeline 300, and these pipeline posture correction devices are arranged at intervals along the length direction of the pre-installed water pipeline 300; then, the crane is controlled to gradually lower the water pipeline 300 onto these pipeline posture correction devices, that is, these pipeline posture correction devices pre-support the pipeline posture correction devices, and at this time, the sling binding the water pipeline 300 is removed; then, by controlling one or more pipeline posture correction devices The single-side correction unit 100 corrects the posture of the water pipeline 300 so that the end of the water pipeline 300 is aligned with the end of the installed water pipeline 300; then, each pipeline posture correction device is controlled to clamp the water pipeline 300, and then the step-by-step propulsion unit 200 is controlled to propel the water pipeline 300, so as to achieve the purpose of connecting the two water pipelines 300; the present invention adopts multiple pipeline posture correction devices to support and correct the water pipeline 300 at multiple points, thereby improving the effect of supporting and correcting the water pipeline 300, and multiple step-by-step propulsion units 200 are used to synchronously propel the water pipeline 300 at multiple points, so that the movement of the water pipeline 300 is smoother, and the assembly errors caused by slipping are avoided. After the assembly is completed, the present invention controls the pipeline posture correction device to loosen the water pipeline 300, and finally, transfers these pipeline posture correction devices to another area where the water pipeline 300 is to be installed, and performs pre-adjustment to ensure that when the next water pipeline 300 is supported by these pipeline posture correction devices, the water pipeline 300 to be installed and the installed water pipeline 300 have completed preliminary alignment. In summary, the present invention can effectively improve the accuracy of assembly and connection between water pipelines 300, improve construction efficiency, reduce work intensity, avoid collisions, damages, etc. of the water pipeline 300, and prevent safety accidents.

[0020] As a preferred embodiment of the present invention, Figure 3-6As shown, the unilateral correction unit 100 includes a mounting seat 101, a supporting correction mechanism and a tube body tightening mechanism 104, and the mounting seat 101, the supporting correction mechanism and the tube body tightening mechanism 104 are arranged in sequence from bottom to top. Among them, the mounting seat 101 and the step-by-step propulsion unit 200 are detachably connected together, and the mounting seat 101 and the supporting correction mechanism are slidably connected. A transverse driving member 102 is arranged between the mounting seat 101 and the supporting correction mechanism, and the transverse driving member 102 is generally a hydraulic cylinder, which can provide stable and sufficient lateral thrust. In this embodiment, an adjustment port 107 is formed between the two supporting correction mechanisms of the pipeline posture correction device, and a tightening port 108 is formed between the two tube body tightening mechanisms 104. The water pipeline 300 is lowered into the adjustment opening 107 by a crane and supported by two supporting correction mechanisms. By controlling the movement of the two supporting correction mechanisms and / or the transverse drive member 102, the vertical posture and / or horizontal posture of the water pipeline 300 is adjusted, thereby achieving the purpose of accurate correction of the water pipeline 300. After the adjustment is completed, the two tube body tightening mechanisms 104 are controlled to move toward each other, so that the tightening opening 108 gradually shrinks until the two tube body tightening mechanisms 104 tightly clamp the water pipeline 300, so that the subsequent step-by-step propulsion unit 200 drives the water pipeline 300 to move longitudinally through the pipeline posture correction device, thereby completing the docking operation. In this embodiment, after the docking is completed, the two tube body tightening mechanisms 104 are controlled to move in opposite directions, and the two tube body tightening mechanisms 104 release the tightening of the water pipeline 300; then, the single-side correction unit 100 is removed from the side of the water pipeline 300.

[0021] As a preferred embodiment of the present invention, Figure 7 , 8As shown, the mounting seat 101 includes a plate-shaped seat body 1011, and a plurality of first sliding grooves 1012 are configured at the upper end of the plate-shaped seat body 1011. The first sliding grooves 1012 are arranged at intervals along the length direction of the water pipeline 300, and each first sliding groove 1012 extends in the transverse direction of the water pipeline 300. In this embodiment, a plurality of first sliding bars 1035 are configured at the lower end of the supporting correction mechanism. The first sliding bars 1035 are arranged one-to-one corresponding to the plurality of first sliding grooves 1012, and the first sliding bars 1035 are slidably assembled in the corresponding first sliding grooves 1012. A first connecting ear 1013 and a second connecting ear 1014 are configured on the plate-shaped seat body 1011. The two ends of the transverse driving member 102 are respectively connected to the first connecting ear 1013 and the supporting correction mechanism, and the step-by-step propulsion unit 200 is connected to the second connecting ear 1014. In this embodiment, the transverse driving member 102 is controlled to move. Due to the limitation of the step-by-step propulsion unit 200, the plate-shaped seat 1011 does not move during the process of the transverse driving member 102 driving the supporting correction mechanism to move. At the same time, the other transverse driving member 102 moves in the opposite direction, so that the two supporting correction mechanisms move in the same direction, thereby achieving the purpose of correcting the horizontal posture of the water pipe 300. In addition, in the process of correcting the horizontal posture and / or vertical posture of the water pipe 300 in this embodiment, the pipe body tightening mechanism 104 is in a non-clamping state for the water pipe 300, so as to prevent the pipe body tightening mechanism 104 from blocking the correction of the water pipe 300.

[0022] As a preferred embodiment of the present invention, Figure 8-13As shown, the support type correction mechanism includes an assembly box 103, a support component 105 and two elastic adjustment components 106. The support component 105 is connected to the assembly box 103, the upper end of the assembly box 103 is connected to the tube body tightening mechanism 104, the lower end of the assembly box 103 is connected to the mounting seat 101, and the two elastic adjustment components 106 are respectively arranged on both sides of the support component 105, and the support component 105 is elastically connected to the assembly box 103 through the two elastic adjustment components 106. The specific structure of the assembly box 103 of this embodiment is that the assembly box 103 includes a box body 1031 and a sealing cover 1032. The sealing cover 1032 is detachably installed at the end of the box body 1031 away from the water pipeline 300, and closes the port of the box body 1031. The above-mentioned multiple first sliding bars 1035 are constructed on the lower end surface of the box body 1031. The upper and lower ends of the box body 1031 are respectively connected to the tube body tightening mechanism 104 and the mounting seat 101; strip holes 1034 are symmetrically constructed on both sides of the box body 1031, and each strip hole 1034 extends along the radial direction of the water pipeline 300. The end surface of the box body 1031 close to the water pipeline 300 is an arc surface, and a plurality of assembly holes 1037 are spaced apart on the arc surface, and an assembly cavity 1033 is formed in the box body 1031. The specific structure of the support assembly 105 of this embodiment is that the support assembly 105 includes an oblique mounting plate 1051 and a plurality of support rods. The oblique mounting plate 1051 is movably assembled in the assembly cavity 1033. Connecting shafts 1052 are symmetrically fixed on both sides of the oblique mounting plate 1051. Each connecting shaft 1052 extends out of a corresponding bar-shaped hole 1034, and the connecting shaft 1052 is connected to a corresponding elastic adjustment assembly 106. The plurality of support rods are evenly mounted on the end surface of the oblique mounting plate 1051 facing the water pipeline 300. The end of each support rod away from the oblique mounting plate 1051 passes through the corresponding assembly hole 1037. A bowl-shaped joint 1056 is constructed at the end of the support rod close to the water pipeline 300, and a joint ball 1057 is movably connected in the bowl-shaped joint 1056. The working principle and advantage of this embodiment are: when the water pipe 300 is lowered into the adjustment port 107 and is gradually contacted by the two supporting correction mechanisms, each joint ball 1057 contacts the lower sides of the outer peripheral surface of the water pipe 300, and as the water pipe 300 is gradually lowered, the force on the joint ball 1057 gradually increases, so that the external force borne by the joint ball 1057 is transmitted to the oblique mounting plate 1051 through the support rod, and then transmitted to the two connecting shafts 1052 by the oblique mounting plate 1051. The two connecting shafts 1052 move synchronously in the two strip holes 1034 respectively, so that the two respectively press the two elastic adjustment components 106, so that the two elastic adjustment components 106 shrink synchronously, thereby playing a buffering role, avoiding hard contact between the water pipe 300 and the joint ball 1057.Moreover, in the process of correcting the posture of the water pipe 300, the present embodiment uses the joint ball 1057 to contact the water pipe 300, thereby achieving the purpose of multi-directional relative movement between the supporting correction mechanism and the water pipe 300, making the posture adjustment of the water pipe 300 smoother and avoiding the support correction mechanism from scratching the outer surface of the water pipe 300.

[0023] As a preferred embodiment of the present invention, Fig.12 As shown, the support rod includes a rod-shaped plug-in portion 1053, a threaded connection portion 1054 and a tubular receiving portion 1055. The threaded connection portion 1054 is configured at one end of the rod-shaped plug-in portion 1053, and the threaded connection portion 1054 is threadedly connected with the oblique mounting plate 1051. One end of the rod-shaped plug-in portion 1053 away from the threaded connection portion 1054 is movably inserted in the tubular receiving portion 1055, and a first hard spring is installed in the tubular receiving portion 1055. The two ends of the first hard spring are respectively connected to the rod-shaped plug-in portion 1053 and the tubular receiving portion 1055, and the bowl-shaped joint 1056 is configured at one end of the tubular receiving portion 1055 extending out of the box body 1031. The working principle and advantages of this embodiment are: this embodiment can adapt to the support and posture adjustment of water pipes 300 with different pipe diameters. Specifically, by rotating each rod-shaped plug-in portion 1053, the length of the rod-shaped plug-in portion 1053 extending out of the box body 1031 is adjusted, thereby adapting to the curvature of the supported position of the water pipe 300, and at the same time, cooperating to adjust the spacing between the two relatively arranged supporting correction mechanisms. In addition, since the rod-shaped plug-in portion 1053 and the tubular receiving portion 1055 are connected in an elastic plug-in manner in this embodiment, when contacting with water pipes 300 with different pipe diameters and bearing external forces, under the pressure of the water pipe 300, these elastically retractable support rods automatically adapt to the pipe diameter of the water pipe 300 (that is, each joint ball 1057 effectively abuts against the outer peripheral surface of the water pipe 300), and in the process of elastic expansion and contraction of the support rod, the support rod plays the role of primary buffer, and the elastic adjustment component 106 plays the role of secondary buffer.

[0024] As a preferred embodiment of the present invention, Fig.13As shown, the elastic adjustment component 106 includes an insertion rod 1062, an insertion tube 1061, a second hard spring 1064, a first adjustment screw 1065 and a first adapter plate 1038. One end of the insertion rod 1062 is sleeved on the outside of the connecting shaft 1052 through an adapter sleeve 1063, and the other end of the insertion rod 1062 is movably inserted in the insertion tube 1061; the second hard spring 1064 is sleeved on the outside of the insertion rod 1062, and the two ends of the second hard spring 1064 are respectively connected to the insertion tube and the adapter sleeve 1063. The first adjusting screw 1065 of this embodiment is rotatably connected to the end of the insertion tube 1061 away from the adapter sleeve 1063, and the first adjusting screw 1065 is threadedly connected to the first adapter plate 1038. The first adapter plate 1038 is detachably connected to the sealing cover 1032 on the assembly box 103, and a first operating hand wheel 1066 is installed at the end of the first adjusting screw 1065 away from the insertion tube 1061. The working principle and advantages of this embodiment are: in this embodiment, when the connecting shaft 1052 moves obliquely downward along the strip hole 1034, the connecting shaft 1052 drives the insertion rod 1062 through the adapter sleeve 1063 to gradually extend into the insertion tube 1061. In this process, the second hard spring 1064 is compressed and stores energy, thereby buffering the force on the support rod. Moreover, in this embodiment, all the first operating hand wheels 1066 on the rotating support correction mechanism can be used to make the first adjusting screw 1065 drive the oblique mounting plate 1051 to move along the extension direction of the strip hole 1034 through the connecting shaft 1052. The oblique mounting plate 1051 is connected obliquely to the water pipe 300 through the support rod thereon, and at the same time, another oblique mounting plate 1051 is connected obliquely to the water pipe 300 relatively through the support rod thereon. In this way, the water pipe 300 is vertically displaced, thereby realizing the correction of the vertical posture of the water pipe 300.

[0025] As a preferred embodiment of the present invention, Fig.14As shown, the tube body tightening mechanism 104 includes a sliding seat 1041, an arc-shaped tightening plate 1043, a second adapter plate 1045 and a second adjusting screw 1046. Among them, a plurality of second sliding grooves 1042 are constructed at the lower end of the sliding seat 1041, and these second sliding grooves 1042 are arranged at intervals along the length direction of the water pipeline 300, and each second sliding groove 1042 extends in the transverse direction of the water pipeline 300. A plurality of second sliding bars 1036 are constructed at the upper end of the box body 1031 of the supporting correction mechanism, and these second sliding bars 1036 are arranged one-to-one with the second sliding grooves 1042, and each second sliding bar 1036 is slidably assembled in the corresponding second sliding groove 1042. In this embodiment, a fixing block 1044 is constructed at the lower position of one end of the arc-shaped tightening plate 1043 facing away from the water pipeline 300, and the fixing block 1044 is detachably connected to the sliding seat 1041. One end of the second adjusting screw 1046 is rotatably connected to the sliding seat 1041, a second adapter plate 1045 is installed on the assembly box 103, the second adjusting screw 1046 is threadedly connected to the second adapter plate 1045, and a second operating hand wheel 1047 is installed at one end of the second adjusting screw 1046 away from the sliding seat 1041. The working principle and advantages of this embodiment are: this embodiment can replace the arc-shaped tightening plate 1043 with different curvatures according to the water pipeline 300 with different pipe diameters; this embodiment drives the second adjusting screw 1046 to rotate by rotating the second operating hand wheel 1047, so that the second adjusting screw 1046 drives the arc-shaped tightening plate 1043 to move toward or away from the water pipeline 300 through the sliding seat 1041, thereby clamping the water pipeline 300 or releasing the clamping of the water pipeline 300. In this embodiment, a rubber anti-skid layer is fixed on the end face of one end of the arc-shaped tightening plate 1043 close to the water pipe 300. When the arc-shaped tightening plate 1043 clamps the water pipe 300, the rubber anti-skid layer not only undergoes spring deformation to adapt to the outer wall of this model of water pipe 300, but also has an anti-skid effect, thereby avoiding slipping when the stepping propulsion unit 200 drives the supporting correction mechanism to move.

[0026] As a preferred embodiment of the present invention, Figure 5 , 15As shown, the step-by-step propulsion unit 200 includes a longitudinal drive member 202, a connecting seat 201, an oblique pivot plate 203 and a gripping seat 208. One end of the longitudinal drive member 202 is mounted on the connecting seat 201, and the other end of the longitudinal drive member 202 is connected to the second connecting ear 1014 on the plate-shaped seat body 1011. The longitudinal drive member 202 is generally a hydraulic cylinder. The connecting seat 201 is pivotally connected to one end of the oblique pivot plate 203 through the first pivot axis 204, and the other end of the oblique pivot plate 203 is pivotally connected to the upper end of the gripping seat 208 through the second pivot axis 206; a first torsion spring 205 is installed at each end of the first pivot axis 204, and the two ends of each first torsion spring 205 are connected to the connecting seat 201 and the oblique pivot plate 203 respectively; a second torsion spring 207 is installed at each end of the second pivot axis 206, and the two ends of each second torsion spring 207 are connected to the oblique pivot plate 203 and the gripping seat 208 respectively. In this embodiment, a first limiting protrusion 210 is constructed at the upper end of the gripping seat 208, and the first limiting protrusion 210 is arranged at a position between the second pivot axis 206 and the connecting seat 201, and the first limiting protrusion 210 is used to abut the lower position of the lower end surface of the oblique pivot plate 203. A second limiting protrusion 211 is configured at one end of the connecting seat 201 close to the oblique pivot plate 203. The second limiting protrusion 211 is located below the first pivot shaft 204. The second limiting protrusion 211 is used to abut against the upper position of the lower end surface of the oblique pivot plate 203. In this embodiment, a plurality of strip-shaped grasping teeth 209 are configured at intervals along the length direction of the grasping seat 208 at the lower end of the grasping seat 208. Each strip-shaped grasping tooth 209 extends in the transverse direction of the grasping seat 208. The working principle and advantage of this embodiment are that the grasping seat 208 of this embodiment is in a state of tightly grasping the ground, and the lower part of the grasping seat 208 extends into the ground. The grasping seat 208 can also be anchored to the ground by an anchor rod, so that the grasping seat 208 and the ground remain fixed. When the anchor rod is not used, the gripping seat 208 is controlled to contact the ground, and under the drive of the longitudinal drive member 202 and the restriction of the first limit protrusion 210 and the second limit protrusion 211, the gripping seat 208 tightly grips the ground. In this way, under the support of the gripping seat 208, the longitudinal drive member 202 drives the corresponding single-sided correction unit 100 to move, so that the single-sided correction unit 100 drives the water pipe 300 to move toward the other water pipe 300 to be aligned; when one movement cannot achieve alignment, the gripping seat 208 can be released from the ground, the longitudinal drive member 202 can be controlled to retract, and the gripping seat 208 can be stepped forward for a distance. After that, the gripping seat 208 is fixed to the ground again, and the longitudinal drive member 202 is repeatedly controlled to drive the single-sided correction unit 100 to move until the ends of the two water pipes 300 are aligned and connected.
