DETAILED DESCRIPTION
[0019] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.
[0020] Example: Figures 1-6The size detection system for docking of marine boiler pipes shown in the figure includes a detection mechanism and a rolling mechanism, the rolling mechanism is installed on the detection mechanism, the detection mechanism includes a detection base 1, a support column 2 is fixedly installed on the detection base 1, a rear mounting plate 3 is fixedly installed on the support column 2, a center bracket 4 is fixedly installed on the rear mounting plate 3, a center spindle 5 is fixedly installed on the center bracket 4, a front end bracket 6 is fixedly installed on the center spindle 5, a drive motor 7 is fixedly installed on the rear mounting plate 3, a rear end runner 8 is rotatably installed on the center spindle 5, a front end runner 9 is rotatably installed on the center spindle 5, a torsion spring is provided between the rear end runner 8 and the front end runner 9, a cross slide bar 10 is slidably installed on the front end bracket 6, and a cross slide bar 10 is rotatably installed on the cross slide bar Measuring wheel 11, the rear end rotating wheel 8 is provided with an arc groove, the horizontal slide bar 10 slides on the arc groove of the rear end rotating wheel 8, the swing frame 12 is rotatably installed on the center bracket 4, the right end of the swing frame 12 is slidably installed with a rear vertical slide bar 13, both ends of the swing frame 12 are provided with slide bars, the rear vertical slide bar 13 is slidably connected with the slide bar at the right end of the swing frame 12, the front end rotating wheel 9 is provided with an arc groove, the right end of the rear vertical slide bar 13 slides on the arc groove of the front end rotating wheel 9, the front vertical slide bar 14 is slidably installed on the front end bracket 6, the front vertical slide bar 14 is slidably connected with the slide bar at the left end of the swing frame 12, and a vertical measuring wheel 15 is rotatably installed on the front vertical slide bar 14, and the vertical measuring wheel 15 and the horizontal measuring wheel 11 respectively contact the inner and outer walls of the boiler pipe to be tested. When the driving motor 7 is started, the rear end rotating wheel 8 is driven to rotate, and the rear end rotating wheel 8 drives the front end rotating wheel 9 to rotate together. The rear end rotating wheel 8 rotates and drives the cross sliding bar 10 to slide horizontally on the front end bracket 6. The front end rotating wheel 9 rotates and drives the rear vertical sliding bar 13 to slide on the front end rotating wheel 9. At the same time, the swing frame 12 swings on the center bracket 4, and the swing frame 12 swings and drives the front vertical sliding bar 14 to slide. The sliding direction of the front vertical sliding bar 14 is opposite to that of the rear vertical sliding bar 13. The front vertical sliding bar 14 moves and drives the vertical measuring wheel 15 to move. The cross sliding bar 10 moves and drives the cross measuring wheel 11 to move. The cross measuring wheel 11 moves and is close to the inner wall of the boiler pipe, and the vertical measuring wheel 15 moves and is close to the outer wall of the boiler pipe. The size of the boiler pipe can be detected by the moving distance of the vertical measuring wheel 15 and the cross measuring wheel 11. Through the design of the torsion spring, after the vertical measuring wheel 15 has been close to the outer wall of the pipe, the front end rotating wheel 9 cannot rotate and the rear end rotating wheel 8 can still continue to rotate until the cross measuring wheel 11 is close to the inner wall of the pipe, thereby reducing the detection error.
[0021] The rolling mechanism includes a lifting base 18, on which an adjustment motor 19 is fixedly mounted. An adjustment screw 20 is fixedly mounted at the output end of the adjustment motor 19. An adjustment slider 21 is slidably mounted on the lifting base 18, threadedly mating with the adjustment screw 20. An adjustment roller 22 is rotatably mounted on the adjustment slider 21, which supports the boiler pipe. When the adjustment motor 19 is activated, the adjustment screw 20 rotates, which in turn slides the adjustment slider 21. This sliding movement of the adjustment slider 21 changes the spacing between the adjustment rollers 22 to accommodate boiler pipes of varying sizes. As the boiler pipe rotates, the vertical measuring wheel 15 and the horizontal measuring wheel 11 rise and fall along the inner and outer walls of the boiler pipe, thereby detecting the circular runout error of the boiler pipe.
[0022] The rolling mechanism includes a support slide 16, which is fixedly mounted on the detection base 1. A lifting cylinder 17 is fixedly mounted on the support slide 16. A lifting seat 18 is fixedly mounted on the telescopic end of the lifting cylinder 17. The lifting seat 18 slides on the support slide 16. The lifting cylinder 17 drives the lifting seat 18 to slide on the support slide 16, adjusting the height to accommodate boiler pipes of different sizes.
[0023] The threads on either side of the adjustment screw 20 run in opposite directions. Two sets of adjustment sliders 21 and adjustment rollers 22 are symmetrically arranged on either side of the lifting base 18. A rolling motor 23 is fixedly mounted on one set of adjustment sliders 21, and the output shaft of the rolling motor 23 is fixedly connected to the adjustment roller 22. When the rolling motor 23 is activated, the adjustment roller 22 rotates, which in turn rotates the boiler pipe, thereby inspecting the entire pipe.
[0024] A secondary support slide bar 24 is fixedly mounted on the detection base 1, a top hinge seat 25 is fixedly mounted on the secondary support slide bar 24, a rotating seat 26 is rotatably mounted on the top hinge seat 25, a rocker arm 27 is fixedly mounted on the rotating seat 26, a pressure wheel 28 is rotatably mounted on the rocker arm 27, and the pressure wheel 28 is pressed against the top of the boiler pipe.
[0025] A torsion spring is provided between the rotating seat 26 and the top hinge seat 25. The torsion spring is used to hold the pressing wheel 28 close to the boiler pipe top.
[0026] The horizontal slide bar 10, the horizontal measuring wheel 11, the swing frame 12, the rear vertical slide bar 13, the front vertical slide bar 14 and the vertical measuring wheel 15 are symmetrically arranged in two groups to uniformly detect the boiler pipes and assist in centering the boiler pipes.
