Description

Technical Field

[0001] The utility model relates to the technical field of pipeline detection, and more specifically, to a large-angle crawling tooling for a pipeline crawler. Background Art

[0002] When the existing crawler performs operation tasks inside an inclined pipeline, when the inclination angle of the pipeline exceeds a certain specific value, the frictional force provided by its own weight will be less than the component force of its own gravity in the axial direction of the pipeline. In this case, the crawler will slip during the uphill process, resulting in an inability to continue moving forward.

[0003] For example, if the inclination angle of the pipeline reaches more than 45°, the component force of the crawler's own gravity along the axial direction of the pipeline will increase significantly, while the increase in the frictional force generated by its own weight is relatively small. Once the component force of gravity exceeds the frictional force, the crawler cannot obtain sufficient grip, and even if the driving device operates at full capacity, it is difficult to overcome the slipping condition and can only come to a standstill.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0039] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0040] Refer to Figures 1 to 2 , which is the first embodiment of the present invention. A large-angle crawling tooling for a pipeline crawler is proposed, which is used for crawling inside a pipeline and includes a crawler main body 1; there are two pressing rods 112, and one ends of the two pressing rods 112 are respectively swingably arranged on both sides of one end of the crawler main body 1. After the pressing rods 112 swing, the other ends of the pressing rods 112 approach or move away from the crawler main body 1; there are two second rubber wheels 113, and the second rubber wheels 113 are rotatably arranged at the other ends of the pressing rods 112 and are used to abut against the inner wall of the pipeline.

[0041] In this embodiment, in order to solve the problem that the wheels of the pipeline crawler slip during the uphill crawling process in a large-angle pipeline in the related art, resulting in the inability to crawl, a large-angle crawling tooling for the pipeline crawler is designed. One end of two pressing rods 112 is swingably arranged on both sides of one end of the crawler body 1 through rotating hinges. The second rubber wheel 113 is made of synthetic rubber with high elasticity and wear resistance and is rotatably arranged at the other end of the pressing rod 112. Specifically, when it is necessary to detect a pipeline with a large rising angle, the crawler body 1 enters the uphill area. At this time, the pressing rod 112 swings away from the crawler body 1, so that the second rubber wheel 113 is closely abutted against the inner wall of the other side of the pipeline, providing a reverse acting force and increasing the friction between the crawler body 1 and the inner wall of the pipeline, thereby ensuring that the crawler body 1 can still crawl stably in the uphill area with a large angle.

[0042] The advantage is that when passing through a pipeline with a large uphill angle, the positions of the pressing rod 112 and the second rubber wheel 113 can be automatically adjusted in real time, so that the crawler body 1 and the second rubber wheel 113 always maintain good contact with the inner wall of the pipeline, enhancing the adaptability in the pipeline. The contact points and friction with the inner wall of the pipeline are increased, significantly improving the stability of the crawler body 1 in a complex pipeline environment, reducing the shaking and offset caused by the change of the pipe diameter, and thus ensuring the accuracy of detection.

[0043] Furthermore, it further includes support rods 114. There are two support rods 114. One end of the two support rods 114 is swingably arranged on both sides of the other end of the crawler body 1. The other end of the support rod 114 is slidably arranged on the pressing rod 112. The swinging of the support rod 114 drives the pressing rod 112 to swing; one end of the first telescopic member 115 is arranged on the pressing rod 112, and the extending end of the first telescopic member 115 is hinged to the other end of the support rod 114. After the first telescopic member 115 extends, the other end of the support rod 114 slides along the pressing rod 112.

[0044] In this embodiment, when it is necessary to detect a pipeline area with a large ascending angle, the first telescopic member 115 responds quickly, starts to extend and applies a strong and stable thrust. This thrust precisely drives the other end of the support rod 114 to smoothly move on the pressing rod 112. Since one end of the pressing rod 112 is swingably arranged on the crawler body 1 through a hinge, this structural design enables the other end of the pressing rod 112 to swing away from the crawler body 1 in an accurate and controllable manner under the push of the support rod 114. This swinging action drives the second rubber wheel 113 installed at the other end of the pressing rod 112 to abut against the inner wall of the pipeline. During this process, a strong reaction force is generated between the second rubber wheel 113 and the inner wall of the pipeline, effectively increasing the friction between the crawler body 1 and the inner wall of the pipeline. This significantly enhanced friction provides sufficient grip and support for the crawler body 1, enabling it to overcome gravity and other resistances and crawl smoothly upward when facing a steeply ascending pipeline area, thus ensuring the smooth progress of the detection work.

[0045] The advantage is that the coordinated cooperation of this structure and action provides crucial support for the pipeline crawler during large-angle uphill detection. For example, in the mountainous laying section of an oil pipeline, pipeline areas with extremely large ascending angles are often encountered. Conventional crawlers may slide or stall due to insufficient friction. However, with this improved tooling design, the crawler can easily handle uphill pipelines with an angle of up to 60° or even steeper and successfully complete tasks such as corrosion detection and wall thickness measurement of the inner wall of the pipeline.

[0046] Furthermore, the crawler body 1 includes a crawler chassis 2; the control device 107 is arranged at one end of the crawler chassis 2; the battery pack 108 is arranged in the middle of the crawler chassis 2; and the receiver 111 is arranged at the other end of the crawler chassis 2.

[0047] In this embodiment, the crawler body 1 is composed of a crawler chassis 2, a control device 107, a battery pack 108, and a receiver 111. The crawler chassis 2 is manufactured by an integrated casting process using high-strength aluminum alloy material, having excellent rigidity and corrosion resistance. The control device 107 is located at one end of the crawler chassis 2 and internally integrates an advanced microprocessor and sensors, capable of real-time monitoring of key parameters such as the speed, position, and attitude of the crawler, and performing precise control and adjustment through complex algorithms. The battery pack 108 is composed of high-performance lithium-ion battery packs 108, installed in the middle of the crawler chassis 2, and ensures long-term stable power supply through an optimized battery management system. The receiver 111 is located at the other end of the crawler chassis 2, adopting the latest wireless communication technology, capable of real-time receiving instructions and data from an external console and quickly transmitting the information collected by the crawler back to the console.

[0048] The advantage is that this reasonable and compact layout enables the crawler to have a uniform center-of-gravity distribution, making its operation more stable and reliable. In various complex pipeline environments, the crawler can maintain a stable posture and speed, reducing the risk of rollover or out-of-control caused by center-of-gravity shift. At the same time, the arrangement of each component is convenient for operation and maintenance, greatly reducing the equipment maintenance cost and downtime. For example, when the battery pack 108 needs to be replaced, the operator only needs to open the specially designed battery compartment door to conveniently and quickly remove the old battery and install a new one, and the whole process only takes a few minutes, greatly improving the work efficiency. Another example is that the control device 107 and the receiver 111 are located at both ends of the crawler chassis 2, reducing signal interference, improving the stability and accuracy of data transmission, and ensuring that the crawler can accurately execute the instructions issued by the external console.

[0049] Furthermore, the crawler chassis 2 includes a chassis mounting frame 101; there are two rotating shafts 102, and the two rotating shafts 102 are rotatably arranged on the chassis mounting frame 101 and are in transmission connection with each other. Both ends of the rotating shaft 102 extend out of the chassis mounting frame 101; the first rubber wheels 103 are arranged at both ends of the rotating shaft 102 for abutting against the inner wall of the pipeline.

[0050] In this embodiment, the crawler chassis 2 is composed of a chassis mounting frame 101, rotating shafts 102 and first rubber wheels 103. The chassis mounting frame 101 is welded by a strong steel structure and has undergone strict stress analysis and optimized design, capable of withstanding huge loads and impacts. The two rotating shafts 102 are made of high-performance alloy steel and are rotatably arranged on the chassis mounting frame 101 through high-precision ball bearings. The rotating shafts 102 are driven by a high-strength chain. The chain is made of a special wear-resistant alloy material and its surface has been hardened, having extremely high wear resistance and tensile strength. The first rubber wheels 103 are made of high-elastic rubber material and are embedded with a strong metal skeleton inside, which can provide good elastic buffering while ensuring sufficient structural strength. When the crawler is working, the two rotating shafts 102 rotate synchronously under the drive of the motor, and drive the first rubber wheels 103 to roll stably on the inner wall of the pipeline through the transmission of the chain, providing strong forward power and support force for the crawler.

[0051] The advantage is that the perfect cooperation between the rotating shaft 102 and the first rubber wheel 103 provides a solid foundation for the stable movement of the crawler in the pipeline. In long-distance, large-slope and heavy-load pipeline inspection tasks, this design can ensure that the crawler moves forward continuously and stably, greatly improving the inspection efficiency and accuracy.

[0052] Furthermore, the two rotating shafts 102 are connected by a chain drive. The crawling chassis 2 further includes a tension rod 104. One end of the tension rod 104 is rotatably arranged on the chassis mounting frame 101; a tension wheel 105 is rotatably arranged at the other end of the tension rod 104 and meshes with the chain; a fastener 106 is arranged at one end of the tension rod 104 for restricting the position of the tension rod 104 on the chassis mounting frame 101.

[0053] In this embodiment, the chain drive system between the two rotating shafts 102 is equipped with a tension adjustment mechanism. The tension rod 104 is made of lightweight aluminum alloy, and one end is rotatably arranged on the chassis mounting frame 101 through a precise rotating joint. The tension wheel 105 is made of wear-resistant nylon material and is rotatably arranged at the other end of the tension rod 104 through a high-precision bearing. The tension wheel 105 meshes tightly with the chain. By adjusting the angle of the tension rod 104, the pressure of the tension wheel 105 on the chain can be changed, thereby realizing precise adjustment of the chain tension. The fastener 106 adopts a combination of high-strength bolts and nuts. The fastener is arranged at the rotating end of the tension rod and can firmly lock the position of the tension rod 104 on the chassis mounting frame 101 to ensure that the chain tension remains stable after adjustment.

[0054] The advantage is that this chain drive tension adjustment mechanism effectively ensures the reliability and stability of the drive system. During long-term operation, even if the chain elongates or loosens due to wear or temperature changes, the position of the tension wheel 105 can be adjusted in time to maintain the good driving state of the chain, reducing failures and energy losses caused by loose or too tight chains.

[0055] Furthermore, the crawler body 1 further includes a receiving mounting frame 3. The receiver 111 is installed on the crawling chassis 2 at the end far from the control device 107 through the receiving mounting frame 3. The receiving mounting frame 3 includes a mounting rod 109. One end of the mounting rod 109 is arranged at the end of the crawling chassis 2 far from the control device 107; a first sliding rod 110 is slidably arranged at the other end of the mounting rod 109, and the receiver 111 is installed on the first sliding rod 110.

[0056] In this embodiment, the receiver 111 of the crawler body 1 realizes flexible position adjustment through a unique receiving mounting bracket 3. The mounting rod 109 of the receiving mounting bracket 3 is made of strong aluminum alloy material, and one end is firmly fixed to the end of the crawler chassis 2 away from the control device 107 by welding or bolt connection. The first slide bar 110 is made of high-precision stainless steel material and is smoothly slidably connected to the mounting rod 109 through a precision linear guide rail. The receiver 111 is fixed on the first slide bar 110 through a mounting seat and can change its position as the first slide bar 110 slides on the mounting rod 109. During the operation of the crawler, when encountering an area with weak signals or strong interference, the operator can remotely control the first slide bar 110 to slide on the mounting rod 109, thereby adjusting the receiver 111 to the position with the best signal to ensure stable data transmission and communication. At the same time, this design enables the crawler body 1 to be applicable to pipes of different diameters, improving the applicability of the crawler body 1.
