Description

Technical Field

[0001] This utility model relates to the field of pipeline repair technology, and in particular to a mechanically manufactured spiral winding lining trenchless repair device. Background Technology

[0002] Long-term operation of water supply pipelines is affected by various factors such as the underground environment, raw water quality, and pipe materials. A large number of water supply pipelines in the water supply network system have exceeded their service life. Aging water pipes are subjected to physical, chemical, and microbial effects, leading to extensive corrosion and scaling on their inner walls, severely impacting water quality and causing secondary pollution. Furthermore, early water supply pipelines had significant defects in their structural pressure resistance design, resulting in frequent pipe bursts and leaks, causing serious economic losses and, more importantly, severely affecting the health and safety of urban residents. Therefore, the maintenance and repair of aging water supply pipelines is urgently needed.

[0003] Mechanical spiral winding lining for pipe repair utilizes a specialized spiral winding machine to spirally wind prefabricated strip profiles inside the old pipe, forming one or more layers of high-strength new pipe lining. During the winding process, precise control ensures the strip profile rotates and advances continuously within the pipe, while mechanisms such as clamping and locking mechanisms ensure a tight connection between the profiles. However, existing winding devices suffer from the following problems:

[0004] 1. When constructing in pipes with small diameters, fixed spiral winding machines are often used and fixed in manholes. The newly wound pipe is pushed forward along the original pipe. However, existing fixed winding machines cannot accurately determine the position of the pipe's central axis during the fixing process. As a result, the lining that is further away from the winding machine is pushed forward, it falls more under its own weight, which can easily cause the far end of the lining to come into contact with the pipe and cause friction, resulting in damage to the lining.

[0005] 2. Existing winding machines can only change different winding ends when dealing with pipes of different diameters, which has limitations and affects the progress of project construction. Utility Model Content

[0006] To address the aforementioned problems, the present invention aims to provide a mechanically manufactured spiral winding lining non-excavation repair device, which solves the problem of the lining wound by existing fixed spiral winding machines not being coaxial with the pipeline axis.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A mechanical spiral winding lining trenchless repair device includes a base, a pair of locking components fixed on the left and right sides of the base for relative movement or immobility between the base and the pipe, a telescopic column fixed above the base along the height direction, a measuring axis component set on the rear side of the movable column of the telescopic column for determining the height position of the pipe's central axis, and a winding component set horizontally on the front side of the movable column of the telescopic column for winding to form an lining that matches the diameter of the pipe.

[0009] The measuring axis assembly includes a mounting base fixed at the middle of the rear side of the movable column inside the telescopic column, a level fixed at the rear side of the mounting base, a bidirectional threaded height adjustment sleeve rotatably mounted on the mounting base and arranged vertically, a pair of movable studs symmetrically and movably arranged on the upper and lower sides of the bidirectional threaded height adjustment sleeve and connected to the threads of the bidirectional threaded height adjustment sleeve with opposite threads, a pair of horizontal fixing plates fixed at the ends of the two movable studs away from the bidirectional threaded height adjustment sleeve, a pair of flexible abutment members fixed at the side of the corresponding fixing plate away from the bidirectional threaded height adjustment sleeve, and two sets of limit rods fixed at the side of the corresponding horizontal fixing plate near the bidirectional threaded height adjustment sleeve and used to limit the rotation of the corresponding movable studs.

[0010] The winding assembly includes an alignment column fixed at the center of the mounting seat on the front side of the movable column inside the telescopic column, a rotating motor fixed at the front end of the alignment column and whose output shaft is coaxial with the alignment column, a rotating column fixed at the front end of the rotating motor and axially fixed to the output shaft of the rotating motor, a plurality of winding sub-assemblies arranged circumferentially at intervals at the front end of the rotating column, and a pump feeder fixed on the rotating column.

[0011] Each of the winding sub-assemblies includes a fixed base fixed to the front end of the rotating column and arranged in a direction perpendicular to the central axis of the rotating column; a sliding rail arranged in front of the fixed base along the length direction of the fixed base; a movable component movably arranged in the sliding rail; a plurality of threaded holes arranged at intervals along the length direction of the fixed base and arranged in the rear side of the fixed base; a fastening screw threaded in the corresponding threaded hole and used to fix the rear end of the movable component to the fixed base; a limiting rail arranged in front of the movable component along the thickness direction of the fixed base; a pair of movable tension plates respectively movably arranged in the limiting rail; an arc adjustment screw rotatably arranged in the limiting rail and arranged along the length direction of the limiting rail and used to drive the two movable tension plates to move synchronously closer to or away from the center of the limiting rail; and a flexible guide plate arranged below the front side of the movable tension plate and fixedly connected to the corresponding movable tension plates on both sides at its left and right ends respectively.

[0012] Each pair of movable tension plates is threadedly connected to a corresponding arc adjustment screw with opposite thread directions.

[0013] More preferably, the two locking components include a hinge seat fixed on the corresponding side of the base, a rotating plate hinged in the hinge seat, and a hammer nail disposed through the rotating plate along the thickness direction for fixed connection with the pipe wall.

[0014] More preferably, each of the arc adjustment screws is provided with its two ends extending out of the side wall of the movable part, and each of the arc adjustment screws is fixed with a pair of rotating blocks at both ends.

[0015] More preferably, the two sets of limiting rod groups include a pair of limiting sub-rods respectively fixed on the left and right sides of the corresponding horizontal fixed plate and passing through the mounting base along the height direction.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model places the base at the pipe opening and rotates the bidirectional threaded adjusting sleeve to drive the movable screws on both sides to extend and abut against the inner wall of the pipe. This causes the movable column in the telescopic column to move up and down to the pipe axis due to the influence of the measuring shaft assembly. At this time, the winding assembly, which is horizontally set to the measuring shaft assembly, moves synchronously to the same height as the pipe. After being wound by the winding assembly, the inner lining tube is made and enters the pipe. This solves the problem of the inner lining wound by the existing fixed spiral winding machine being coaxial with the pipe axis.

[0018] 2. This utility model adjusts the position of the movable part along the sliding track before winding the inner lining, locks the movable part to the fixed seat with the fastening screw, and then adjusts the curvature of the flexible guide plate by rotating the curvature adjustment screw, so that the curvature of the guide plate matches the pipe, thereby making the wound inner lining match the pipe.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, this embodiment of a mechanical spiral winding lining trenchless repair device includes a base 1, a pair of locking components 2 fixed on the left and right sides of the base 1 and used to make the base 1 move or remain stationary relative to the pipe, a telescopic column 3 fixed above the base 1 along the height direction, a measuring axis component 4 set on the rear side of the movable column in the telescopic column 3 and used to determine the height position of the pipe's central axis, and a winding component 5 horizontally set on the front side of the movable column in the telescopic column 3 and used to wind and form an lining that matches the diameter of the pipe.

[0029] The measuring axis assembly 4 includes a mounting base 41 fixed at the middle of the rear side of the movable column inside the telescopic column 3, a level 42 fixed at the rear side of the mounting base 41, a bidirectional threaded height adjustment sleeve 43 rotatably mounted on the mounting base 41 and arranged vertically, a pair of movable studs 44 symmetrically and movable on the upper and lower sides of the bidirectional threaded height adjustment sleeve 43 and connected with the threads of the bidirectional threaded height adjustment sleeve 43 in the opposite direction, a pair of horizontal fixing plates 45 fixed at the ends of the two movable studs 44 away from the bidirectional threaded height adjustment sleeve 43, a pair of flexible abutment members 46 fixed at the side of the corresponding fixing plate away from the bidirectional threaded height adjustment sleeve 43, and two sets of limiting rod groups 47 fixed at the side of the corresponding horizontal fixing plate 45 near the bidirectional threaded height adjustment sleeve 43 and used to limit the rotation of the corresponding movable studs 44.

[0030] The winding assembly 5 includes an alignment column 51 fixed at the center of the mounting seat 41 on the front side of the movable column inside the telescopic column 3, a rotary motor 52 fixed at the front end of the alignment column 51 and whose output shaft is coaxial with the alignment column 51, a rotary column 53 fixed at the front end of the rotary motor 52 and axially fixedly connected to the output shaft of the rotary motor 52, a plurality of winding sub-assemblies 54 arranged circumferentially at intervals at the front end of the rotary column 53, and a pump feeder 55 fixed on the rotary column 53.

[0031] Each winding sub-assembly 54 includes a fixed base 541 fixed to the front end of the rotating column 53 and arranged perpendicular to the central axis of the rotating column 53; a sliding rail 542 arranged along the length of the fixed base 541 on the front side of the fixed base 541; a movable member 543 movably disposed within the sliding rail 542; a plurality of threaded holes 544 spaced apart along the length of the fixed base 541 on the rear side of the fixed base 541; and fastening screws 545 threadedly connected in the corresponding threaded holes 544 for fixing the rear end of the movable member 543 to the fixed base 541. The following components are provided: a limiting rail 546 located at the front end of the movable part 543 along the thickness direction of the fixed base 541; a pair of movable tension plates 547 respectively movably located within the limiting rail 546; an arc adjustment screw 548 rotatably located within the limiting rail 546 and along the length direction of the limiting rail 546, used to drive the two movable tension plates 547 to move synchronously closer to or further away from the center of the limiting rail 546; and a flexible guide plate 549 located below the front side of the movable tension plate 547 and whose left and right ends are respectively fixedly connected to the corresponding movable tension plates 547 on both sides.

[0032] A pair of movable tension plates 547 are threadedly connected to corresponding arc adjustment screws 548, with the thread directions being opposite.

[0033] When using this product, for construction of pipes of different diameters, each winding sub-assembly 54 is adjusted. After removing the fastening screws 545, the corresponding movable part 543 is moved along the sliding rail 542 to the corresponding position, and then the fastening screws 545 are tightened to fix the movable part 543 and the fixed seat 541. This adjusts the distance between the movable part 543 and the central axis of the rotating column 53, which corresponds to the radius of the pipe. Then, the rotating blocks 6 at both ends of the corresponding arc adjustment screw 548 are rotated, driving the arc adjustment screw 548 to rotate. This controls the two corresponding movable tension plates 547 to move synchronously away from or towards the center of the arc adjustment screw 548, thereby driving the flexible guide plate 549 to stretch outward or squeeze inward until the arc of the guide plate 549 corresponds to the arc of the pipe side wall, so that the guide plate 549 matches the pipe. The base 1 is placed at the pipe opening, and the level 42 is observed horizontally. When the liquid level fluctuates, adjust the position of the base 1 left and right until the liquid level on the level gauge 42 is level and stable. This indicates that the telescopic column 3 is on the pipe diameter line. Then, fix the base 1 to the pipe opening using the locking components 2 on both sides. At this time, rotate the bidirectional threaded height adjustment sleeve 43, which will drive the movable studs 44 on the upper and lower sides to move synchronously away from the bidirectional threaded height adjustment sleeve 43. When the abutment 46 on one movable stud 44 abuts against the inner wall of the pipe, continue to rotate the bidirectional threaded height adjustment sleeve 43. Under the action of the abutment resistance, the movable column inside the telescopic column 3 will move away from the abutment point until the abutment 46 on the other movable stud 44 abuts against the other side of the pipe wall. At this time, the center of the bidirectional threaded height adjustment sleeve 43 corresponds to the central axis of the pipe. This makes the winding component 5 at the center of the bidirectional threaded height adjustment sleeve 43 on the central axis of the pipe, thus completing the height positioning.

[0034] like Figure 1 and Figure 2 As shown, the two locking components 2 include a hinge seat 21 fixed on the corresponding side of the base 1, a rotating plate 22 hinged in the hinge seat 21, and a hammer nail 23 that passes through the rotating plate 22 along the thickness direction and is used for fixed connection with the pipe wall.

[0035] When using this product, place the base 1 at the pipe opening and observe the fluctuation of the liquid level in the level 42. Adjust the position of the base 1 left and right until the liquid level in the level 42 is horizontal and stable. This indicates that the telescopic column 3 is on the pipe diameter line. Rotate the rotating plates 22 on both sides down, and then hammer the nails 23 into the pipe in sequence to fix the rotating plates 22 to the inner wall of the pipe.

[0036] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, each arc adjustment screw 548 has its two ends extending out of the side wall of the movable part 543, and each arc adjustment screw 548 has a pair of rotating paddles 6 fixed at both ends.

[0037] When using this product, the operator can easily rotate the arc adjustment screw 548 by using the rotating dial 6.

[0038] like Figure 1 , Figure 2 and Figure 3 As shown, the two sets of limiting rods 47 include a pair of limiting sub-rods 471 that are respectively fixed on the left and right sides of the corresponding horizontal fixed plate 45 and pass through the mounting base 41 along the height direction.

[0039] When this product is in use, the limiting rod 471 is set to lock the self-rotation of each movable stud 44, preventing the situation where the movable stud 44 cannot be driven to move along the height when the bidirectional threaded height adjusting sleeve 43 is rotated.

[0040] The working principle of this device is as follows:

[0041] Step 1: When constructing pipes of different diameters, adjust each winding sub-assembly 54. After removing the fastening screws 545, move the corresponding movable part 543 along the sliding rail 542 to the corresponding position, and then tighten the fastening screws 545 to fix the movable part 543 and the fixed seat 541. This adjusts the distance between the movable part 543 and the central axis of the rotating column 53, which corresponds to the radius of the pipe. Then, rotate the rotating blocks 6 at both ends of the corresponding arc adjustment screw 548 to drive the arc adjustment screw 548 to rotate. This controls the two corresponding movable tension plates 547 to move synchronously away from or towards the center of the arc adjustment screw 548, thereby driving the flexible guide plate 549 to stretch outward or squeeze inward until the arc of the guide plate 549 corresponds to the arc of the pipe side wall, so that the guide plate 549 matches the pipe.

[0042] Step 2: Place the base 1 at the pipe opening and observe the liquid level fluctuation in the level 42 horizontally. Adjust the position of the base 1 left and right until the liquid level in the level 42 is horizontal and stable. This means that the telescopic column 3 is on the pipe diameter line. Rotate the rotating plates 22 on both sides down, and then knock the nails 23 into the pipe in sequence to fix the rotating plates 22 to the inner wall of the pipe.

[0043] Step 3: At this time, rotate the bidirectional threaded height adjustment sleeve 43, causing the movable studs 44 on the upper and lower sides to move synchronously away from the bidirectional threaded height adjustment sleeve 43. When the abutment 46 on one side of the movable stud 44 abuts against the inner wall of the pipe, continue to rotate the bidirectional threaded height adjustment sleeve 43, so that under the action of the abutment resistance, the movable column inside the telescopic column 3 moves away from the abutment point until the abutment 46 on the other side of the movable stud 44 abuts against the other side of the pipe wall. At this time, the center of the bidirectional threaded height adjustment sleeve 43 corresponds to the central axis position of the pipe, so that the winding assembly 5 corresponding to the center of the bidirectional threaded height adjustment sleeve 43 is on the central axis of the pipe, thereby completing the height positioning.

[0044] Step 4: The manufactured strip pipe is pumped to the center of each winding sub-assembly 54 through the pump feeder 55. At the same time, the rotating motor 52 is started to drive each winding sub-assembly 54 to rotate axially. This causes the pipe entering the center of the winding sub-assembly 54 to be guided by each guide plate 549 and wound into a spiral shape, and continuously transported into the pipeline to complete the pipeline repair.

[0045] The above description is only a specific embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural transformations made based on the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
