[0020] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. Obviously, the embodiments described are only a part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making any creative efforts are within the scope of protection of the present application.
[0021] like Figures 1 to 3 The pipeline crawling vehicle climbing test device shown includes a slope adjustment component 1, a bottom support mechanism 2, and a pair of protractors 3.
[0022] The slope adjustment assembly 1 includes a semicircular tube 11. When the semicircular tube 11 is in a horizontal state, one end of the semicircular tube 11 is placed on a first bracket 111. Dome plates 12 are respectively formed at both ends of the semicircular tube 11. Buffer blocks 13 are provided on the inner sides of the two dome plates 12. In this embodiment, the buffer blocks 13 are made of rubber. Extension blocks 14 are respectively formed at both ends of the outer circumference of the dome plate 12 connected to the other end of the semicircular tube 11. A rotating rod 15 is provided on the outer end surface of the extension block 14. The slope adjustment assembly 1 also includes a pair of rotating seats 16. The two rotating rods 15 are respectively rotatably matched with the rotating seats 16. An adjusting rod 17 is provided on one side of the extension block 14. A handle 18 is provided at one end of the adjusting rod 17. When the semicircular tube 11 is in a horizontal state, one end of the handle 18 is placed on the second bracket 181. A marking plate 19 is provided at one end of the outer circumference of the adjusting rod 17. The thickness of the marking plate 19 is less than 5 mm.
[0023] The bottom support mechanism 2 is arranged at the lower end of the slope adjustment component 1, and is used to support the semicircular tube 11 from the bottom when the semicircular tube 11 rotates to a predetermined angle. The bottom support mechanism 2 includes a bottom block 21 fixed to the lower end of the outer peripheral side of the semicircular tube 11. The lower end surface of the bottom block 21 is provided with a T-shaped groove along the axial direction of the semicircular tube 11. An inverted T-shaped block 22 is slidably fitted in the T-shaped groove. A ring is provided at the lower end of the inverted T-shaped block 22. A rotating tube 23 with an axis perpendicular to the axis of the semicircular tube 11 is rotatably fitted in the ring. Vertical blocks 24 are respectively provided at both ends of the rotating tube 23, and a support block 25 is provided at the lower end of the vertical block 24. In order to prevent sliding, the support block 25 is made of rubber.
[0024] The sides of the two protractors 3 are both penetrated by openings, and the rotating rod 15 is passed through the openings. The protractors 3 are fixedly placed on the third bracket 31. The center of the circle of the scale of the protractor 3 is on the axis of the rotating rod 15. The protractor 3 is transparent, and the outer end face of the marking plate 19 is in contact with one side of the protractor 3. By observing the position of the marking plate 19, the current inclination angle of the semicircular tube 11 can be known.
[0025] Working method:
[0026] Before each test, the pipe crawler with the set load is placed in the semicircular tube 11, preferably in the middle of the semicircular tube 11, and then the front and rear ends of the pipe crawler are blocked, specifically by hand, or with the help of two plates similar to the buffer block 13. Then, by holding the handle 18, pull up the adjustment rod 17 to further drive the semicircular tube 11 to rotate until the marking plate 19 indicates that the current inclination angle of the semicircular tube 11 is at the predetermined angle for this test. Then, when the bottom end surface of the support block 25 is horizontal, try to push the inverted T-shaped block 22 towards the direction close to the axis of the rotating rod 15, so that the bottom support mechanism 2 can stably support the semicircular tube 11.
[0027] Then adjust the power of the pipeline crawler to the predetermined power for the test, and then remove the front and rear blocks of the pipeline crawler. If the pipeline crawler cannot climb the slope, it will fall on the buffer block 13 located below, indicating that the current power is insufficient for climbing under the current load. If the pipeline crawler can climb the slope, its climbing speed can be observed and calculated, for example, the time it takes to contact the buffer block 13 located above can be calculated, and the speed can be calculated in combination with the distance moved, so that the subsequent power design can be adjusted to increase or decrease for use in actual work.
[0028] The above are only some of the embodiments listed in this application and are not intended to limit this application.
