[0041] The utility model proposes a pipeline repair device 100, which includes a driving mechanism 10, an abutment ring 20 and a walking chassis 60; wherein the driving mechanism 10 includes a driving assembly 11 and a telescopic assembly 12 connected to the driving assembly 11, the driving assembly 11 is used to drive the telescopic assembly 12 to expand or contract along the radial direction of the pipeline, and the telescopic assembly 12 can extend into or out of the pipeline when contracted; the abutment ring 20 is arranged on the outer periphery of the telescopic assembly 12, and the abutment ring 20 includes a plurality of abutment blocks 21, and the plurality of abutment blocks 21 are sequentially overlapped and arranged along the circumference of the pipeline so that the abutment ring 20 is in a tightened state, and the telescopic assembly 12 drives the plurality of abutment blocks 21 to extend in the radial direction of the pipeline when expanding in the radial direction of the pipeline.

The two ends of each abutment block 21 along its extension direction are respectively a head end 211 and a tail end 212. Among any two adjacent abutment blocks 21, the head end 211 of one abutment block 21 is snap-fitted with the tail end 212 of the other abutment block 21 when the abutment ring 20 is in the inner support state, so that the multiple abutment blocks 21 are fixedly connected in sequence along the circumferential direction and pressed against the inner wall of the pipe along the circumferential direction when the abutment ring 20 is in the inner support state; the walking chassis 60 is equipped with a lifting frame 70, and the driving assembly 11 is installed on the lifting frame 70.

When repairing the pipeline, the telescopic assembly 12 and the abutment ring 20 in a tightened state are extended into the pipeline and extended to the damaged part of the pipeline, and the telescopic assembly 12 is driven to expand by the driving assembly 11 so that the multiple abutment blocks 21 are fixedly connected in sequence, so that the abutment ring 20 is in an inner support state, and the abutment ring 20 in the inner support state is tightly pressed against the inner wall of the pipeline at the damaged part of the pipeline, and the abutment ring 20 in the inner support state can block and repair the damaged part of the pipeline by itself, thereby completing the repair of the damaged pipeline. The head end 211 and the tail end 212 of the abutment block 21 are respectively formed with a first clamping member 2111 and a second clamping member 2121. In any two adjacent abutment blocks 21, the first clamping member 2111 of one abutment block 21 is clamped and matched with the second clamping member 2121 of another abutment block 21, so that the plurality of abutment blocks 21 can be fixedly connected in sequence along the circumferential direction, so that the abutment ring 20 is in an inner support state. The design is ingenious and the fixed connection is convenient. The telescopic assembly 12 is extended out of the pipeline, and the telescopic assembly 12 and the abutment ring 20 in the inner support state can be detached, so that the abutment ring 20 in the inner support state is left at the damaged part of the pipeline, and the damaged pipeline can be repaired. There is no need to dig out the damaged pipeline and replace the damaged pipeline, which is simple, convenient and low in cost.

[0043] In addition, the driving assembly 11 is installed on the traveling chassis 60, and the traveling chassis 60 can drive the driving structure 111 to move, the abutting ring 20 and the cutting assembly 50 to move, which is convenient for transportation. The driving assembly 11 can be raised and lowered relative to the traveling chassis 60 by the lifting frame 70, and the height of the driving assembly 11 can be adjusted so that the telescopic assembly 12 and the abutting ring 20 can be extended into pipes of different heights, which is more applicable.

[0044] In one embodiment, a first clamping piece 2111 is provided at the head end 211, and a second clamping piece 2121 is provided at the tail end 212; among any two adjacent abutment blocks 21, the first clamping piece 2111 of one abutment block 21 is engaged with the second clamping piece 2121 of the other abutment block 21 when the abutment ring 20 is in the internal support state, so that the multiple abutment blocks 21 are fixedly connected in sequence along the circumferential direction when the abutment ring 20 is in the internal support state.

[0045] Specifically, Figure 4 As shown, through the clamping cooperation of the first clamping member 2111 and the second clamping member 2121, multiple abutment blocks 21 can be quickly fixedly connected in sequence along the circumferential direction when the abutment ring 20 is in the inner support state, which is simple and convenient.

[0046] In one embodiment, the abutment block 21 is an arc-shaped block protruding outward; the head end 211 forms a first clamping edge 2112, the first clamping edge 2112 is inclined from the head end 211 toward the tail end 212, and the first clamping member 2111 is a plurality of clamping teeth 2113 formed on the first clamping edge 2112 and distributed in sequence along the extension direction of the first clamping edge 2112; the tail end 212 forms a second clamping edge 2122, the second clamping edge 2122 is inclined from the tail end 212 toward the head end 211, and the second clamping member 2121 is a plurality of clamping grooves 2123 formed on the second clamping edge 2122 and distributed in sequence along the extension direction of the second clamping edge 2122; the plurality of clamping grooves 2123 are used to be clamped and matched with the plurality of clamping teeth 2113 in a one-to-one correspondence.

[0047] Specifically, Figure 4 As shown, the abutment block 21 is an arc-shaped block protruding outward, which can better fit the inner wall of the pipeline and has a better sealing and repairing effect on the damaged part of the pipeline. And among any two adjacent abutment blocks 21, the abutment block 21 cooperates with the multiple clamping teeth 2113 of another abutment block 21 through multiple clamping grooves 2123, so the connection between any two adjacent abutment blocks 21 is more convenient and firm, and the abutment ring in a supporting state formed by the multiple abutment blocks 21 fixedly connected in sequence along the circumferential direction has higher firmness and reliability.

[0048] In one embodiment, the telescopic component 12 includes a plurality of blades 121, which are arranged outside the driving component 11 along the circumferential ring of the pipeline, and the two ends of each blade 121 along its extension direction are respectively a hinge end 1211 and a repair end 1212, and the hinge end 1211 of each blade 121 is hinged to the driving component 11, and the number of blades 121 is consistent with the number of abutment blocks 21 and corresponds one to one, and each abutment block 21 is attached to its corresponding blade 121 when the abutment ring 20 is in a tightened state, and the driving component 11 drives the repair ends 1212 of the plurality of blades 121 to move in a direction away from or close to the driving component 11, so as to correspondingly expand or contract the telescopic component 12 along the radial direction of the pipeline.

[0049] Specifically, Figure 2 and Figure 3As shown, the telescopic assembly 12 includes a plurality of blades 121. The driving assembly 11 drives the repair ends 1212 of the plurality of blades 121 to move away from or toward the driving assembly 11, so that the telescopic assembly 12 can be expanded or contracted along the radial direction of the pipeline. Before the telescopic assembly 12 and the abutment ring 20 in a tightened state are extended into the pipeline, the repair ends 1212 of each blade 121 are moved close to the driving assembly 11 to shrink the telescopic assembly 12, and each abutment block 21 in the abutment ring 20 in a tightened state is attached to its corresponding blade 121. After the telescopic component 12 and the abutment ring 20 in a tightened state are extended into the pipe, the driving component 11 drives each fan blade 121 to move away from the driving component 11, so that the telescopic component 12 expands, and the multiple abutment blocks 21 are driven by the multiple fan blades 121 to move in a direction away from the driving component 11 until they abut against the inner wall of the pipe, and the multiple abutment blocks 21 are fixedly connected in sequence along the circumferential direction to form a tightening ring in a supporting state. The expansion or contraction of the telescopic component 12 can be achieved by driving the repair ends 1212 of the multiple fan blades 121 to move, which is simple and convenient.

[0050] In one embodiment, the driving assembly 11 includes a driving structure 111, a mounting sleeve 112 and a transmission rod 113; wherein the mounting sleeve 112 can be extended into or out of the pipe, and the two ends of the mounting sleeve 112 along its extension direction are respectively a connecting end 1121 and a free end 1122, the connecting end 1121 is connected to the driving structure 111, a plurality of blades 121 are arranged outside the free end 1122, and a plurality of hinged ends 1211 are hinged to the free end 1122 at intervals along the circumference of the mounting sleeve 112; the transmission rod 113 extends into the mounting sleeve 112, one end of the transmission rod 113 is connected to the driving structure 111, and the other end of the transmission rod 113 extends out of the free end 1122 and is connected to a plurality of hinged ends 1211 along its circumference. The sliding rods 1131 are distributed at intervals; the multiple fan blades 121 are all arc-shaped fan blades 121 with the same bending direction, and each fan blade 121 is formed with an arc-shaped groove 1213. The number of sliding rods 1131 is consistent with that of the fan blades 121 and they correspond one to one. The end of each sliding rod 1131 away from the transmission rod 113 forms a sliding block 1132 that slidably cooperates with the corresponding arc-shaped groove 1213; the driving structure 111 is used to drive the transmission rod 113 to rotate or rotate in the opposite direction, so as to drive the sliding block 1132 to slide along the arc-shaped groove 1213 toward or away from the hinge end 1211 through the transmission rod 113, so that the repair ends 1212 of the multiple fan blades 121 move away from or toward the free end 1122.

[0051] Specifically, Figures 1 to 3Each fan blade 121 is an arc-shaped fan blade 121 with a consistent bending direction. The hinged ends 1211 of the multiple fan blades 121 are hinged to the free end 1122 of the mounting sleeve 112 at circumferential intervals along the mounting sleeve 112. When the repair ends 1212 of the multiple fan blades 121 are moved to be arranged close to the free end 1122, the arc-shaped fan blades 121 with a consistent bending direction enable the multiple fan blades 121 to be stacked in sequence and wrapped around the outside of the free end 1122, so that the telescopic assembly 12 is more compact when retracted. An arc groove 1213 is formed on each fan blade 121, and a transmission rod 113 is also penetrated through the mounting sleeve 112. One end of the transmission rod 113 is connected to the driving structure 111, and the other end extends out of the free end 1122 of the mounting sleeve 112, and even one end of the free end 1122 is connected to a plurality of sliding rods 1131 distributed at intervals along the circumference of the transmission rod 113, and one end of the sliding rod 1131 away from the transmission rod 113 forms a sliding block 1132 that slidably cooperates with the corresponding arc groove 1213. The driving structure 111 drives the transmission rod 113 to rotate, and the transmission rod 113 drives the multiple sliding rods 1131 at its end to rotate, so as to drive the slider 1132 on each sliding rod 1131 to move relative to the corresponding fan blade 121 along the arc groove 1213 in the direction close to the hinge end 1211, thereby driving the repair end 1212 of the corresponding fan blade 121 to move in the direction away from the free end 1122, so that the telescopic component 12 expands radially along the pipeline; the driving structure 111 drives the transmission rod 113 to rotate in the opposite direction, and the transmission rod 113 drives the multiple sliding rods 1131 at its end to rotate in the opposite direction, so as to drive the slider 1132 on each sliding rod 1131 to move relative to the corresponding fan blade 121 along the arc groove 1213 in the direction away from the hinge end 1211, thereby driving the repair end 1212 of the corresponding fan blade 121 to move in the direction close to the free end 1122, so that the telescopic component 12 contracts radially along the pipeline. The repair end 1212 of the blade 121 can be driven to move away from the free end 1122 or toward the free end 1122 simply by driving the transmission rod 113 to rotate or reversely rotate, thereby realizing the expansion or contraction of the telescopic component 12, which is simple and convenient.

[0052] In one embodiment, the transmission rod 113 is a hollow transmission rod 113 , and the air delivery pipe 30 is disposed inside the transmission rod 113 .

[0053] Specifically, Figure 2 and Figure 3 As shown, the transmission rod 113 is a hollow transmission rod 113, and the air delivery pipe 30 is inserted into the transmission rod 113, so that the internal space of the transmission rod 113 is utilized, and the structure is more compact.

[0054] In one embodiment, the driving structure 111 is used to drive the transmission rod 113 and the mounting sleeve 112 to rotate synchronously and in opposite directions.

[0055] Specifically, by driving the transmission rod 113 and the mounting sleeve 112 to rotate synchronously and in the opposite direction through the driving structure 111, the speed of relative movement between the mounting sleeve 112 and the transmission rod 113 can be accelerated, thereby driving the fan blades 121 to move faster in a direction away from the free end 1122 or in a direction close to the free end 1122, so as to accelerate the expansion or contraction speed of the telescopic assembly 12.

[0056] In one embodiment, each abutment block 21 is provided with a first magnetic component 22, and each fan blade 121 is provided with a second magnetic component 1214. The first magnetic component 22 of each abutment block 21 is magnetically matched with the second magnetic component 1214 of its corresponding fan blade 121 to attach each abutment block 21 to its corresponding fan blade 121 when the abutment ring 20 is in a tightened state.

[0057] Specifically, Figures 2 to 4 As shown, the abutment block 21 can be attached to the corresponding fan blade 121 relatively quickly and firmly through the magnetic attraction cooperation between the first magnetic member 22 on the abutment block 21 and the second magnetic member 1214 on the corresponding fan blade 121. After the telescopic assembly 12 expands the abutment ring 20 to the supporting state, the abutment ring 20 in the supporting state can be separated from the telescopic assembly 12 by simply contracting the telescopic assembly 12 to separate the first magnetic member 22 from the corresponding second magnetic member 1214, which is simple and convenient.

[0058] In one embodiment, the first magnetic component 22 is a magnetic metal, and the second magnetic component 1214 is an electromagnet. When the first magnetic component 22 and its corresponding second magnetic component 1214 need to be separated, the first magnetic component 22 and its corresponding second magnetic component 1214 can be separated by cutting off the power of the second magnetic component 1214, which is simple and convenient.

[0059] In one embodiment, a repair film is provided on the outer side of the abutting ring 20 , and when the abutting ring 20 is in the inner supporting state, the repair film is pressed against the inner wall of the pipe along the circumferential direction.

[0060] Specifically, by providing a repair film on the outside of the abutment ring 20, when the abutment ring 20 is in an internal support state, the abutment ring 20 in the internal support state presses the repair film against the inner wall of the damaged part of the pipe, thereby better sealing the damaged part of the pipe and achieving a better repair effect.

[0061] In one embodiment, the pipeline repair device 100 further includes:

[0062] An air delivery pipe 30, the air delivery pipe 30 is installed on the driving component 11;

[0067] Specifically, Figure 1 As shown, the knife handle 51 and the knife head 52 on the knife handle 51 are extended into the pipe and contact the connecting portion 412 of the airbag 41. The driving component 11 drives the knife handle 51 to move along the circumference of the pipe, so that the connecting portion 412 of the airbag 41 can be cut. The connecting portion 412 of the airbag 41 and the airbag 41 are cut apart, which is simple and convenient.

[0068] In one embodiment, the handle 51 includes a telescopic section 511, a first hinged section 512 and a second hinged section 513. One end of the telescopic section 511 is arranged on the driving assembly 11 and can move along the circumference of the pipeline.
