[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figure 1 A device for quickly detecting the bending accuracy of large metal pipes comprises a screw jacking mechanism 1, a platform rotating mechanism 2, a platform tilting mechanism 3 and a pipe clamping mechanism 4. The platform rotating mechanism 2, the platform tilting mechanism 3 and the pipe clamping mechanism 4 are sequentially mounted on the screw jacking mechanism 1. The screw jacking mechanism 1 is used to lift the mechanism mounted thereon. The screw jacking mechanism 1 is the basic support and lifting system of the entire detection device. When detecting the bending degree of large pipes, it is very difficult to lift them by manpower because the pipes are large and have a correspondingly large weight. A large amount of manpower and time are required. The screw jacking mechanism 1 is used to lift the heavy pipes, thereby reducing manpower and improving efficiency.

[0024] The platform rotating mechanism 2 is used to adjust the angles of the platform tilting mechanism 3 and the pipe clamping mechanism 4 in the horizontal plane. During the process of clamping the pipe, the clamping angle and orientation need to be adjusted. Through the rotating auxiliary ball 202 and the rotating platform 201 inside the platform rotating mechanism 2, smoother rotation can be achieved and stability can be improved.

[0025] The platform tilting mechanism 3 is used to adjust the angle between the pipe clamping mechanism 4 and the horizontal plane. The platform tilting mechanism 3 drives the tilting platform 301 to form a certain angle with the horizontal plane through the turbine 309 and the worm 308, so as to better adapt to the bending angle of the pipe, thereby achieving the effect of fully adapting to the pipe path.

[0026] The pipe clamping mechanism 4 is used for clamping the pipe. The pipe clamping mechanism 4 can not only clamp and support the pipe, but also can be adapted to clamp and support pipes of different diameters, thus improving versatility.

[0027] See also Figure 2-5The screw jacking mechanism 1 includes a base 101, a motor installation opening 1013 is provided on the base 101, a servo motor 109 is installed in the motor installation opening 1013, a pulley 110 is provided on the servo motor 109, a diamond bearing seat 104 and a diamond bearing seat 2 112 are respectively installed on the top and bottom of the base 101, a ball screw 103 is installed between the diamond bearing seat 104 and the diamond bearing seat 2 112, a pulley 110 is installed at the bottom of the ball screw 103, a synchronous belt 111 is provided between the two pulleys 110, and a ball screw nut 105 is installed on the ball screw 103. The base 101 plays a role in supporting the entire device. The servo motor 109 drives the synchronous belt 111 and drives the ball screw 103 to rotate through the pulley 110 installed thereon. The rotation of the ball screw 103 drives the ball screw nut 105 to move up and down, so that the mobile platform 106 moves up and down under the guidance of the fixed column 107 and the guide sleeve 108. As the mobile platform 106 moves up and down, the mobile column 102 thereon also moves up and down, thereby playing the role of lifting the pipe clamping mechanism 4.

[0028] The base 101 is also provided with a through hole 1011 and a through hole 2 1012. A fixed column 107 is provided between the through hole 2 1012. A mobile platform 106 is provided on the fixed column 107. The fixed column 107 is used to limit the up and down movement direction of the mobile platform 106 to ensure that the mobile platform 106 is accurate and does not deviate when moving up and down. The mobile platform 106 is provided with a mounting hole 1061, a through hole 3 1062 and a mounting hole 2 1063. The fixed column 107 is slidably installed in the mounting hole 1061. A guide sleeve 108 is also installed on the mounting hole 1061. The guide sleeve 108 is used to further regulate the consistency of the movement direction of the mobile platform 106. The ball screw nut 105 is fixedly installed on the mounting hole 2 1063, and the ball screw 103 is installed in the mounting hole 2 1063. The mobile column 102 is fixedly installed on the through hole 3 1062, and the mobile column 102 passes through the through hole 1011 upward. The bottom of the moving column 102 is fixedly mounted in the through hole 3 1062 on the moving platform 106 , and the top of the moving column 102 can pass through the base 101 under the movement of the moving platform 106 , thereby playing the role of the lifting platform rotation mechanism 2 .

[0029] See also Figure 6-8The platform rotating mechanism 2 includes a fixed plane 206, on which a mounting hole 3 2061, a motor mounting hole 2062 and a mounting hole 4 2063 are provided. The top of the moving column 102 is fixedly connected in the mounting hole 3 2061. The fixed plane 206 is fixedly connected to the top of the moving column 102. When the moving column 102 moves up and down, the fixed plane 206 can be driven to move up and down, and further drive the entire platform rotating mechanism 2 to move up and down. A rotating ball fixing seat 205 is installed on the mounting hole 4 2063. The rotating ball is fixed to limit the rotation auxiliary ball 202 placed on its top. A rotating auxiliary ball 202 is provided on the top of the rotating ball fixing seat 205. A rotating platform 201 is pressed on the top of the rotating auxiliary ball 202. An annular concave raceway 2011 is provided on the bottom surface of the rotating platform 201. The concave raceway 2011 fits with the rotating auxiliary ball 202. When the rotating platform 201 rotates driven by the rotating shaft 1 204, through the engagement between the concave roller track 2011 at the bottom and the rotating auxiliary ball 202, the rotating auxiliary ball 202 will rotate on the top of the rotating ball fixing seat 205 when the rotating platform 201 rotates, and provide uniform support for the rotation of the rotating platform 201. This makes the rotating platform 201 rotate more smoothly and improves the stability of the rotation.

[0030] A diamond-shaped bearing seat three 207 is arranged at the bottom of the fixed plane 206, a flange 203 is arranged in the middle of the bottom surface of the rotating platform 201, a rotating shaft one 204 is arranged between the flange 203 and the diamond-shaped bearing seat three 207, and the flange 203 fixes one end of the rotating shaft one 204 to the rotating platform 201.

[0031] The first rotating shaft 204 is provided with a second pulley 208, the second motor mounting opening 2062 is provided with a second servo motor 210, the second servo motor 210 is provided with a second pulley 208, and a second synchronous belt 209 is provided between the second pulleys 208. The above is the prior art and will not be described in detail here.

[0032] See also Figure 9-12 The platform tilting mechanism 3 includes a left base 303 and a right base 310, which are fixedly mounted on the rotating platform 201 in parallel, and the left base 303 and the right base 310 are mounting bases of the platform tilting mechanism 3. A rotation auxiliary seat 3031 and a mounting seat 1 3033 are disposed on the left base 303 and the right base 310, and a rotation axis 2 3032 is disposed on the rotation auxiliary seat 3031. The rotation auxiliary seat 3031 and the rotation axis 2 3032 thereon serve as the rotation axis of the fixed slide rail 311, so that the fixed slide rail 311 performs a circular motion around the rotation axis 2 3032 when being lifted.

[0033] The left base 303 and the right base 310 have the same main body shape, but the left base 303 is also provided with a mounting seat 2 3034, a mounting seat 3 3035 and a mounting seat 4 3036, a servo motor 3 304 is mounted on the mounting seat 3 3035, a worm 308 is mounted between the mounting seat 2 3034 and the mounting seat 4 3036, a bearing 1 306 is also mounted on the mounting seat 4 3036, a retaining ring 307 is mounted on the worm 308, and the worm 308 and the servo motor 3 304 are connected via a plum blossom coupling 1 305. The above is the prior art and will not be described in detail here.

[0034] Bearing No. 2 312 is provided on the mounting seat No. 1 3033 of the left base 303 and the right base 310, and a tilting rotating shaft 302 is assembled between the bearing No. 2 312. A turbine 309 is provided at one end of the tilting rotating shaft 302, and the turbine 309 is meshed with the worm 308. When the servo motor No. 304 drives the tilting rotating shaft 302 to rotate, the tilting rotating shaft 302 can drive the moving component 313 to rotate around the tilting rotating shaft 302, thereby lifting one end of the fixed slide rail 311 to achieve the tilting of the tilting platform 301.

[0035] The tilting rotation axis 302 is located at both ends of the left base 303 and the right base 310, and the moving assembly 313 is fixedly installed. The moving assembly 313 includes a rotating rod 3133, one end of the rotating rod 3133 is provided with a mounting hole 5 3134, and the tilting rotation axis 302 is fixedly installed in the mounting hole 5 3134. The other end of the rotating rod 3133 is rotatably provided with a rotating shaft 3131, and both ends of the rotating shaft 3131 are provided with a moving auxiliary ball 3132. When the tilting rotation axis 302 drives the rotating rod 3133 to rotate, the moving auxiliary ball 3132 at one end of the rotating rod 3133 will move upward and outward in an arc, thereby lifting the end of the fixed slide rail 311 away from the rotating seat 3111 upward, thereby realizing the tilting of the tilting platform 301.

[0036] The left base 303 and the right base 310 are both provided with a fixed rail 311 on the second rotation axis 3032. A rotating seat 3111 is provided at one end of the fixed rail 311. The rotating seat 3111 is rotatably mounted on the second rotation axis 3032. The second rotation axis 3032 serves as the rotation axis of the fixed rail 311. Two limiting rails 3112 are provided at the bottom of the fixed rail 311. The moving auxiliary ball 3132 of the moving assembly 313 is located in the limiting rail 3112. During the rotation process, the moving auxiliary ball 3132 is limited in the limiting rail 3112. During the rotation process, the moving auxiliary ball 3132 will drive one end of the fixed rail 311 to lift upward, thereby driving the tilting platform 301 above the fixed rail 311 to tilt.

[0037] See also Figure 13-14The pipe clamping mechanism 4 includes a limit block 403 and a movable clamping block 409. The limit blocks 403 are two and are fixedly mounted in parallel on the tilting platform 301. A linear slide rail 404 is arranged on the limit block 403. The limit block 403 is used to install the linear slide rail 404 and fix the linear slide rail 404 on the tilting platform 301.

[0038] Two movable clamping blocks 409 are arranged opposite to each other between the two linear slide rails 404, and the linear slide rails 404 are also used to provide a limit for the movement of the movable supporting block. The movable clamping block 409 is provided with a ball screw nut 410, and a bidirectional screw 402 is passed through the ball screw nut 410. Since two movable clamping blocks 409 are provided, and the two movable clamping blocks 409 need to realize the clamping action, the two clamping blocks move toward each other or away from each other during movement, so the rotation of the bidirectional screw 402 can realize this movement mode between the two clamping blocks. In addition, the arc-shaped notch 4091 provided on the movable clamping block 409 enables the movable clamping block 409 to have two ways of clamping the pipe fittings, one of which is that the two movable clamping blocks 409 are parallel to the pipe fittings and clamp them from the side of the pipe fittings; the other is that the two movable clamping blocks 409 are perpendicular to the pipe fittings, and the pipe fittings are directly placed on the notches 4091 of the two movable clamping blocks 409.

[0039] The two ends of the bidirectional screw rod 402 are respectively provided with a rear bearing seat 401 and a front bearing seat 405, which are fixedly mounted on the tilting platform 301. A servo motor mounting seat 406 is also fixedly mounted on the tilting platform 301. A servo motor 407 is mounted on the servo motor mounting seat 406. The servo motor 407 and the bidirectional screw rod 402 are connected via a plum blossom coupling 408. The above is the prior art and will not be described in detail here.

[0040] See also Fig.15 When the device is in use, several large-scale thin-walled bent pipe curvature rapid detection devices need to be connected in sequence through the workbench 5, so as to be arranged to adapt to the trajectory of the pipe fittings, and then the pipe fittings are placed on these large-scale thin-walled bent pipe curvature rapid detection devices, and then the various large-scale thin-walled bent pipe curvature rapid detection devices are gradually adjusted so that the devices at various positions fit the shape and trajectory of the pipe fittings, so as to detect the pipe fittings.

[0041] Working principle: During the inspection, multiple large thin-walled curved pipe bending rapid detection devices need to cooperate with each other, put the pipe, and then the four mechanisms of a single device need to be set up. First, the screw jacking mechanism 1 is lifted to the required height, then the platform rotation mechanism 2 is rotated to the appropriate angle, then the platform tilting mechanism 3 is tilted to the required angle, and finally the pipe clamping mechanism 4 adjusts the clamping distance. After all adjustments are completed, the pipe can be placed on the pipe clamping mechanism 4 of multiple detection devices.

[0042] First, the screw lifting mechanism 1 is lifted. First, the servo motor 109 drives the pulley 110 to rotate, thereby driving the ball screw 103 to rotate. Since the ball screw nut 105 is fixedly connected to the mobile platform 106, the mobile platform 106 rises, and the four moving columns 102 arranged on the mobile platform 106 move upward under the lifting of the mobile platform 106, thereby lifting the platform rotating mechanism 2 upward.

[0043] The second is the rotation of the platform rotating mechanism 2. The servo motor 210 drives the rotating shaft 1 204 to rotate, and the rotating shaft 1 204 rotates to drive the rotating platform 201 thereon to rotate. The rotating ball fixing seat 205 and the rotating auxiliary ball 202 below provide support for the rotation of the rotating platform 201.

[0044] Next is the tilting of the platform tilting mechanism 3. The servo motor 304 drives the worm 308 to rotate, and the worm 308 drives the turbine 309 to rotate, which further drives the tilting rotation shaft 302 to rotate.
