Description

Technical Field

[0001] The invention belongs to the technical field of pipeline transportation and detection, and in particular relates to a transportation pipe layout device for pipeline safety detection. Background Art

[0002] Existing pipeline leak detection and inspection devices include pipeline clamps and moving components. By directly installing the detection head on the inner side of the pipeline clamp, and the pipeline clamp can keep the detection head at a fixed distance from the pipeline and then move quickly on the pipeline, long pipelines can be continuously and quickly safely inspected.

[0003] However, after the pipeline safety inspection is completed, the pipelines that need to be replaced cannot be automatically and quickly laid out. Instead, the location of the defective pipeline needs to be manually recorded and the pipeline needs to be transported to the location before laying out the pipeline. This makes the pipeline replacement efficiency after the inspection low, and it is impossible to lay out the pipeline at the defective location while inspecting the pipeline, which makes it inconvenient to replace the defective pipeline later.

[0004] The Chinese patent with the authorization announcement number CN202193021U discloses a self-loading and unloading tunnel pipe laying machine, including a chassis mounted on a vehicle body, a steering wheel control device mounted in the middle of one side of the chassis, and two sets of outrigger mechanisms mounted on the other side of the chassis; the outrigger mechanisms are composed of load-bearing outriggers and outrigger cylinders; a set of unloading and pipe clamping mechanisms are respectively mounted at both ends of the chassis, and the loading and unloading and pipe clamping mechanisms are composed of a flip arm, a swing arm cylinder, an "L"-shaped frame and a flip cylinder, the swing arm cylinder drives the flip arm, and the flip cylinder drives the "L"-shaped frame; the outrigger cylinder, the swing arm cylinder and the flip cylinder are connected to the engine. Its scheme has the functions of loading, transporting, unloading and laying pipes.

[0005] However, this solution can only lay one pipeline at a time and cannot transport multiple pipelines or achieve long-distance continuous pipe laying. Summary of the invention

DETAILED DESCRIPTION

[0039] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0040] See also Figure 1-Figure 9 , the present invention provides a technical solution:

[0041] like Figure 1-Figure 9 As shown, a pipe-laying device for pipeline safety detection includes a mobile trolley 1, a pipe-laying device and a detection device, wherein the detection device is located at the front of the mobile trolley 1, and the detection device includes a telescopic mechanical arm 12 and a pipeline detection device 13 located at the front end of the telescopic mechanical arm 12;

[0042] The pipe laying device is located at the body of the mobile trolley 1, and the pipe laying device includes a carriage 3, a driving layer 4 and a pipeline layer 5 from top to bottom. A push pipe assembly 2 is provided outside the left side of the carriage 3 along the forward direction of the mobile trolley 1, and an electric roller shutter 6 is provided on the right side of the carriage 3 along the forward direction of the mobile trolley 1. A limit plate 7 is provided on the outer side of the electric roller shutter 6. A pipeline drop cavity 71 is formed between the electric roller shutter 6 and the limit plate 7. A buffer assembly 8 and a width adjustment assembly 9 are provided at the bottom of the pipeline drop cavity 71.

[0043] The carriage 3 is used to store the pipe 11, the pipe pusher assembly 2 is used to push the pipe 11 in the carriage 3 into the pipe drop chamber 71, the electric roller shutter 6 is adjusted according to the height of the pipe 11 in the carriage 3, the buffer assembly 8 is used to reduce the speed of the pipe 11 falling, and the width adjustment assembly 9 is used to adjust the width of the pipe drop chamber 71;

[0044] A driving mechanism 41 is provided in the driving layer 4, and the driving mechanism 41 is used to drive the push tube assembly 2 and the electric roller blind 6 to operate synchronously, and the driving mechanism 41 is also used to drive the width adjustment assembly 9;

[0045] A hydraulic station 51 is provided in the pipeline layer 5 , and the hydraulic station 51 is connected to the push pipe assembly 2 and the buffer assembly 8 respectively.

[0046] Through the above technical solution, multiple pipes 11 are temporarily stored in the carriage 3, the mobile trolley 1 is moved to the pipeline 11 to be tested, and the telescopic mechanical arm 12 is extended to cooperate the pipeline detection device 13 at the front end with the pipeline 11 to be tested, so as to realize the detection of the pipeline 11 to be tested. As the mobile trolley 1 moves, long-distance and uninterrupted pipeline 11 detection can be realized. At this time, when the pipeline detection device 13 detects that there is a problem with a certain section of the pipeline 11, the pipe laying device is started.

[0047] The driving mechanism 41 first drives the width adjustment component 9 to adjust the width of the pipe falling cavity 71, so that the width of the pipe falling cavity 71 is just matched with the diameter of the temporarily stored pipe 11. The width adjustment component 9 can adapt to pipes 11 of different diameters, and then the electric roller shutter 6 and the push-tube component 2 are synchronously started according to the stacking height of the pipes 11 in the carriage 3, so that the push-tube component 2 and the electric roller shutter 6 are at the same horizontal line with the top row of pipes 11. At this time, the push-tube component 2 pushes the pipe 11 in the carriage 3 over the electric roller shutter 6 and into the pipe falling cavity 71. At the same time, the buffer component 8 rises to receive the pipe 11 and drive the pipe 11 to move slowly downward, and then the pipe 11 slides down from the rear of the mobile car 1 to complete the pipe laying.

[0048] The combination of the pipe laying device and the detection device can detect the pipeline 11 in real time and complete the pipe laying at the defective position simultaneously, thereby improving the efficiency of the pipeline 11 and reducing the labor intensity of manual laying. At the same time, it can realize detection and pipe laying in narrow spaces such as tunnels.

[0049] like Figure 2 As shown, the driving mechanism 41 includes a driving motor 42, a first transmission shaft assembly 43, a second transmission shaft assembly 44, a third transmission shaft assembly 45 and a fourth transmission shaft assembly 46. The driving motor 42 is a dual-shaft motor, and a first clutch friction disc 421 and a second clutch friction disc 422 are respectively disposed on both sides of the driving motor 42;

[0050] The first transmission shaft assembly 43 and the second transmission shaft assembly 44 are respectively located on both sides of the motor shaft of the driving motor 42, the first transmission shaft assembly 43 is meshed with the third transmission shaft assembly 45 through bevel gear reversing, a third clutch friction disc 431 is provided on the side of the first transmission shaft assembly 43 close to the driving motor 42, the third clutch friction disc 431 cooperates with the first clutch friction disc 421, one end of the third transmission shaft assembly 45 is meshed with the fourth transmission shaft assembly 46 through bevel gear reversing, the third transmission shaft assembly 45 is arranged along the left and right directions of the carriage 3, the fourth transmission shaft is located outside the left side of the carriage 3 and arranged along the forward direction of the carriage 3;

[0051] A fourth clutch friction disc 441 is provided on the side of the second transmission shaft assembly 44 close to the drive motor 42, and the fourth clutch friction disc 441 cooperates with the second clutch friction disc 422. The other side of the second transmission shaft assembly 44 is meshed with the turbine worm assembly through a bevel gear reversing. The motor seat of the drive motor 42 is slidingly connected to the bottom plate of the drive layer 4 through a sliding assembly. A telescopic cylinder 423 is provided on one side of the drive motor 42, and the cylinder seat of the telescopic cylinder 423 is fixed on the bottom plate of the drive layer 4. The piston rod of the telescopic cylinder 423 is connected to the drive motor 42, and the telescopic cylinder 423 is connected to the hydraulic station 51 through a pipeline.

[0052] Combined with the specific structure of the above-mentioned driving mechanism 41 and as Figure 1-Figure 3 As shown, the working principle of the width adjustment component 9 is as follows:

[0053] The width adjustment assembly 9 includes a support beam 91, a linear rail slider assembly 92 and a gear rack transmission assembly 93. The support beam 91 is fixed to the right side of the body of the mobile cart 1. The gear rack transmission assembly 93 is located in the pipeline layer 5. The limit plate 7 is an L-shaped structure. The bottom plate of the limit plate 7 is slidably connected to the support beam 91 through the linear rail slider assembly 92. One side of the bottom plate of the limit plate 7 extends into the pipeline layer 5. The rack in the gear rack transmission assembly 93 is fixed to the limit plate 7. The drive shaft in the gear rack transmission assembly 93 is connected to the turbine in the turbine and worm assembly. The second transmission shaft assembly 44 is power-connected to the gear rack transmission assembly 93 through the turbine and worm assembly.

[0054] When starting the pipe laying device, it is first necessary to adjust the distance between the limit plate 7 and the electric roller shutter 6 through the width adjustment component 9, that is, adjust the width of the pipe drop chamber 71, so that only one pipe 11 in the carriage 3 can enter the pipe drop chamber 71 through the push pipe component 2 at a time, and the width adjustment component 9 can adapt to pipes 11 of different diameters. Since the driving mechanism 41 adopts a power source, when it is necessary to run the width adjustment component 9, the telescopic cylinder 423 is used to drive the driving motor 42 as a whole to move toward the second transmission shaft assembly 44, so that the second clutch friction disk 422 and the fourth clutch friction disk 441 are in contact to complete synchronous rotation. At this time, the rotation of the driving motor 42 will drive the second transmission shaft assembly 44 to rotate. The second transmission shaft assembly 44 is matched with the transmission of the turbine worm assembly below through the bevel gear reversing. The turbine in the turbine worm assembly is located in the pipeline layer 5, and the worm extends from the pipeline layer 5 into the driving layer 4 to cooperate with the second transmission shaft assembly 44;

[0055] At the same time, a gear rack transmission assembly 93 is provided on one side of the limit plate 7 extending into the pipeline layer 5. The rack in the gear rack assembly is fixed to the limit plate 7, and the turbine is fixed on the transmission shaft of the gear rack transmission assembly 93. Therefore, the turbine can be driven to rotate by the worm, and the turbine drives the gear on the same transmission shaft to rotate. The meshing of the gear and the rack realizes the horizontal movement of the limit plate 7. Finally, the limit plate 7 is driven by the driving motor 42 to move horizontally along the support beam 91 to realize the width adjustment of the pipeline falling cavity 71.

[0056] At the same time, it can be known that the worm gear has a self-locking property. After the width adjustment assembly 9 completes the adjustment, the second clutch friction plate 422 of the drive motor 42 is disengaged from the fourth clutch friction plate 441. At this time, due to the existence of the worm gear assembly, when the push tube assembly 2 pushes the pipeline 11 to abut against the limit plate 7, the limit plate 7 will not slide, thereby ensuring the stability of the limit plate 7.

[0057] Continue as Figure 1-Figure 3As shown, the bottom plate size of the carriage 3 is smaller than the bottom plate size of the driving layer 4, and support columns 31 are provided at the four corners of the carriage 3. The electric roller shutter 6 includes a chain plate 61 and a reel 62. The reel 62 is located in the driving layer 4, and the chain plate 61 passes through the driving layer 4 and extends into the carriage 3. The chain plate 61 is slidably connected to two groups of columns on the right side of the carriage 3, and the reel 62 is meshed with one end of the third transmission shaft assembly 45 through a bevel gear reversing.

[0058] The electric roller shutter 6 is used to support the pipes 11 of the carriage 3 laterally. When the pipes need to be laid, the chain plate 61 is dropped according to the stacking height of the pipes 11 in the carriage 3, leaving space for the top row of pipes 11 to pass through. At this time, the pipe 11 is pushed from the right side into the pipe falling cavity 71 on the left side under the action of the pipe pushing assembly 2.

[0059] The specific lifting principle of the electric roller shutter 6 is as follows: the drive motor 42 is driven by the telescopic cylinder 423 to move in the direction of the first rotating shaft assembly, so that the first clutch friction disk 421 and the third clutch friction disk 431 are pressed tightly. At this time, the drive motor 42 can drive the first rotating shaft assembly to rotate. Since the first transmission shaft assembly 43 is meshed with the third transmission shaft assembly 45 through the bevel gear reversing, and the third rotating shaft assembly is connected to the reel 62 through the bevel gear reversing, the drive motor 42 can drive the reel 62 to rotate and retract the chain plate 61.

[0060] At the same time, because both sides of the chain plate 61 are located in the slide grooves of the support column 31, the chain plate 61 can only move up and down along the slide grooves, ensuring the stable movement of the chain plate 61. At the same time, the width of the chain plate 61 between the two groups of support columns 31 is the width of the compartment 3, which can ensure that the push pipe assembly 2 can push the pipe 11 directly through the chain plate 61 between the two groups of support columns 31, and the pipe 11 will not be blocked by the corner interference of the support column 31.

[0061] like Figure 3-Figure 5 As shown, the working principle of the push tube assembly 2 is as follows:

[0062] The push tube assembly 2 includes a screw slider assembly 21 and a multi-stage hydraulic cylinder 22. The screw slider assembly 21 is perpendicular to the driving layer 4. The bottom of the screw in the screw slider assembly 21 is meshed with the fourth transmission shaft assembly 46 through a bevel gear reversing. The screw length of the screw slider assembly 21 is adapted to the height of the carriage 3. The cylinder seat of the multi-stage hydraulic cylinder 22 is fixed on the slider in the screw slider assembly 21. The multi-stage hydraulic cylinder 22 is perpendicular to the left side body of the carriage 3.

[0063] When laying pipes, according to the stacking height of the pipes 11 in the carriage 3, it is necessary to drive the multi-stage hydraulic cylinder 22 to be on the same horizontal line with the top row of pipes 11 through the lead screw slider assembly 21, and then push the pipes 11 into the pipe drop chamber 71 through the multi-stage hydraulic cylinder 22. Specifically, the telescopic cylinder 423 drives the drive motor 42 to move in the direction of the first rotating shaft assembly, so that the first clutch friction disc 421 and the third clutch friction disc 431 are pressed tightly, and the drive motor 42 can drive the first rotating shaft assembly to rotate. Since the first transmission shaft assembly 43 is meshed with the third transmission shaft assembly 45 through the bevel gear reversing, and the third rotation shaft assembly is connected to the fourth transmission shaft assembly 46 through the bevel gear reversing, and the lead screw slider assembly 21 is connected to the fourth transmission shaft assembly 46 through the bevel gear reversing, the drive motor 42 can finally drive the lead screw to rotate, and then the slider moves up and down along the lead screw, completing the up and down position adjustment of the multi-stage hydraulic cylinder 22.

[0064] At the same time, since the two ends of the third transmission shaft assembly 45 are respectively connected to the reel 62 and the push tube assembly 2, the reel 62 and the push tube assembly 2 can operate synchronously, ensuring that the chain plate 61 and the multi-stage hydraulic cylinder 22 rise and fall at the same time, and keeping the highest point of the chain plate 61, the uppermost row of pipes 11 and the multi-stage hydraulic cylinder 22 on the same horizontal line, so that the multi-stage hydraulic cylinder 22 can push the pipe 11 and fall into the pipe falling cavity 71.

[0065] Furthermore, a vertical slot 23 is provided on the left side body of the carriage 3 at the position corresponding to the multi-stage hydraulic cylinder 22, so that the piston rod of the multi-stage hydraulic cylinder 22 can be easily extended into the carriage 3. At the same time, the maximum extension distance of the multi-stage hydraulic cylinder 22 is adapted to the width of the carriage 3, ensuring that the multi-stage hydraulic cylinder 22 can push the farthest pipe 11.

[0066] Furthermore, a flap 32 is provided at the rear of the carriage 3 , and the flap 32 can be lowered to facilitate the early transportation of multiple pipes 11 into the carriage 3 .

[0067] like Figure 6-Figure 7 As shown, the working principle of the buffer assembly 8 is as follows:

[0068] The buffer assembly 8 includes a support plate 81 and a support hydraulic cylinder 82. Two groups of the support hydraulic cylinders 82 are located in the middle of the mobile car 1. The cylinder seats of the support hydraulic cylinders 82 pass through the bottom plate of the limit plate 7 and are fixed to the limit plate 7. The piston rods of the support hydraulic cylinders 82 are hinged to the bottom of the support plate 81. The maximum extension distance of the support hydraulic cylinders 82 is adapted to the height of the carriage 3.

[0069] The supporting hydraulic cylinder 82 further adjusts the extended height according to the height of the chain plate 61 to keep the supporting plate 81 flush with the top of the chain plate 61. When the pipe 11 enters the pipe falling cavity 71, it can directly fall on the supporting plate 81, and then the supporting hydraulic cylinder 82 resets to drive the pipe 11 to move downward.

[0070] Furthermore, the size of the limit plate 7 is larger than that of the chain plate 61, and a folding shed 72 is provided on both sides of the chain plate 61 and the limit plate 7. One side of the folding shed 72 is connected to the support column 31, and the other side of the folding shed 72 is connected to the limit plate 7. An opening 73 for the pipe 11 to slide out is provided at the bottom of the folding shed 72 near the rear side of the mobile cart 1.

[0071] The folding shelves 72 on both sides can prevent the pipe 11 in the pipe falling cavity 71 from sliding out from both sides, playing a blocking role. At the same time, when the pipe 11 is at the bottom, since the piston rod of the supporting hydraulic cylinder 82 is hinged to the bottom of the supporting plate 81, the supporting hydraulic cylinder 82 on the side far away from the hole 73 of the two groups of supporting hydraulic cylinders 82 is lifted, causing the support plate 81 to tilt. At this time, the pipe 11 on the support plate 81 will slide down from the opening 73 to complete the pipe laying.

[0072] like Figure 8 As shown, the working state of the pipe laying device is displayed. At this time, the support plate 81, the chain plate 61, the uppermost pipe 11, and the multi-stage hydraulic cylinder 22 are on the same horizontal line. The multi-stage hydraulic cylinder 22 pushes the pipe 11 from one side so that the pipe 11 closest to the chain plate 61 enters the support plate 81, and the pipe 11 is supported by the support plate 81 and moved downward.

[0073] like Fig. 9 As shown, further, the pipeline detection device 13 includes a telescopic claw, a detection sensor 14 and a telescopic roller 15, the detection sensor 14 is located at the end of the telescopic claw, and the telescopic roller 15 is located on the inner side of the telescopic claw.

[0074] Through the above technical solution, the telescopic mechanical arm 12 drives the pipeline detection device 13 to move above the pipeline to be tested 11, and then the telescopic claw is opened and clamped outside the pipeline to be tested 11, and detection is performed through the detection sensor 14 at the end of the telescopic claw. The detection sensor 14 can be replaced according to the specific detection type. The detection sensor 14 can be an acoustic sensor, an electromagnetic sensor, an infrared sensor, etc., and at the same time, it is abutted against the pipeline 11 through the telescopic roller 15, so that when the mobile trolley 1 drives the safety detection device to move, long-distance uninterrupted detection is achieved through the telescopic roller 15, and at the same time, the telescopic roller 15 can rebound and then reset when encountering the joint of the pipeline 11.

[0075] Furthermore, the hydraulic station 51 is connected to the telescopic cylinder 423, the supporting hydraulic cylinder 82 and the multi-stage hydraulic cylinder 22 through pipelines respectively, and the power is increased by the hydraulic station 51.
