[0029] The lifting base 1 is equipped with four movable wheels 11 at the bottom corners to drive the auxiliary device to move. After moving into position, the movable wheels 11 have their own brakes to stop. The top of the lifting base 1 is fixedly equipped with a base plate 12. The lifting base 1 drives the base plate 12 to rise and fall through the scissor telescopic mechanism. The two ends of the base plate 12 are respectively connected to the positioning component 2 and the positioning conveying component 3.

[0030] The lifting base 1 includes two mating plates arranged vertically and symmetrically arranged scissor units on both sides of the mating plates. The lifting of the base plate 12 is adjusted by the rotation of a rotating adjusting cylinder between the two sets of scissor units. Mounting rods are respectively provided between the upper and lower ends of the two scissor units.

The bottom ends of the connecting plate 21 are vertically fixedly provided with slide rods 24. The base plate 12 is fixedly provided with through holes on both sides, and the slide rods 24 pass through the through holes. In conjunction with the lifting cylinder 23, the connecting plate 21 is driven to rise or fall, thereby adjusting the height of the positioning component 2, which is convenient for clamping and fixing the pipe 5 for positioning.

[0032] The positioning and conveying assembly 3 further includes a bracket 31, a rotating seat 33, a mounting plate 34, a guide block 35, and a guide rail 36. Multiple brackets 31 are fixedly arranged at intervals above the rotating seat 33. Each bracket 31 has a V-shaped frame, and rollers 32 are rotatably mounted at both ends of each bracket 31. The axis of the rollers 32 is parallel to the inclined surface of the bracket 31. One roller 32 is driven by a transmission motor (not shown in the figure), and the multiple rollers 32 can be driven to rotate synchronously through a transmission sprocket and transmission chain cooperation mechanism. A rotating sleeve 331 is fixedly arranged in the middle of the lower surface of the rotating seat 33. A rotating shaft 332 is fixedly arranged inside the rotating sleeve 331. The sleeve 31 is fitted with a mounting plate 34. The rotating seat 33 is rotatably connected to the mounting plate 34. The rotating sleeve 331 has a mating rod fixedly installed on both sides. The mounting plate 34 has a guide rail 36 fixedly installed on both sides of its lower surface. The guide rail 36 has a guide block 35 slidably installed on the guide rail 36. The guide block 35 has a connecting sleeve rod 351 rotatably installed on its side. The connecting sleeve rod 351 is rotatably connected to the mating rod on the rotating sleeve 331. The guide block 35 is internally threaded with a lead screw 37. The two ends of the lead screw 37 are rotatably connected to the rotating seats fixedly installed at both ends on the mounting plate 34. The lead screw 37 is driven to rotate by a rotating motor (not shown in the figure). The two guide blocks 35 move synchronously in opposite directions.

[0033] The positioning and conveying assembly 3 also includes a vertically arranged mating clamp 38. An adjusting gear 310 is rotatably arranged in the middle of the side of the rotating seat 33 away from the positioning assembly 2. Slide rails 39 are respectively arranged on both sides of the adjusting gear 310. The surface of the slide rails 39 is parallel to the axis of the roller 32. An adjusting rack 311 is slidably arranged on the slide rails 39. The two sides of the adjusting gear 310 are respectively meshed with the two adjusting racks 311. The ends of the two adjusting racks 311 that are far apart from each other are fixedly connected to the mating clamp 38. The adjusting gear 310 is driven to rotate by a clamping motor (not shown in the figure). The two mating clamps 38 cooperate to clamp the docking pipe 6.

[0034] The mounting plate 34 has four fixed lifting rods 341 at its bottom corners. Each lifting rod 341 is internally threaded with a connecting rod 312. The connecting rod 312 is rotatably connected to one corner of the base plate 12. The connecting rod 312 is driven by a worm gear mechanism 313 to raise the mounting plate 34, which is used to adjust the height of the docking pipe 6 and facilitate the positioning of the docking pipe 6 and the fixed pipe 5.

[0035] Each clamping assembly 4 further includes a mounting block 41, a first rotating rod 42, a second rotating rod 43, and an adjusting rod 44. The mounting block 41 is fixedly mounted outside the extension arc plate 221. The side of the mounting block 41 away from the extension arc plate 221 is rotatably connected to the first rotating rod 42. The other end of the first rotating rod 42 is rotatably connected to the second rotating rod 43. The other end of the second rotating rod 43 is rotatably mounted with the adjusting rod 44. The mounting rod is horizontally fixedly mounted on the side of the mounting block 41 facing the positioning and conveying assembly 3. The surface of the mounting rod is parallel to the axis of the fixed pipe 5. A limit rod 411 is fixedly mounted on the mounting rod. The adjusting rod 44 is slidably mounted. Within the limiting rod 411, and with the adjusting rod 44 moving radially along the fixed pipe 5, a positioning arc plate 45 is fixedly installed at one end of the adjusting rod 44. The positioning arc plate 45 can abut against the end wall of the docking pipe 6. The rotating rod 42 is driven to rotate by an adjusting motor (not shown in the figure). When the adjusting clamping assembly 4 cooperates to clamp and position the docking pipe 6, the adjusting rotating rod 42 rotates, driving the positioning conveying assembly 3 to rotate, thereby driving the adjusting rod 44 to move along the limiting rod 411, and driving the positioning arc plate 45 to move closer to the docking pipe 6 until the positioning arc plate 45 contacts the pipe wall of the docking pipe 6. A ball bearing (not shown in the figure) can also be installed on the arc surface of the positioning arc plate 45 facing the docking pipe 6. When the positioning conveying assembly 3 moves the docking pipe 6 closer to the fixed pipe 5, the ball bearing can assist the docking pipe 6 in moving, avoiding friction between the positioning arc plate 45 and the pipe wall of the docking pipe 6, thus affecting the surface aesthetics of the docking pipe 6.

[0036] The limiting rod 411 is horizontally fixed with a detection rod 46 on the side facing the positioning and conveying assembly 3, and two distance sensors 47 are spaced apart on the detection rod 46 in the horizontal direction.

[0037] The brake system of the rotating motor, adjusting motor, clamping motor and transmission motor can be reliably locked. It acts directly on the motor shaft through mechanical friction or electromagnetic force, and forcibly prevents the motor and load from rotating when the power is off or the motor stops.

[0038] The device also includes a control system, which is electrically connected to the rotating motor, adjusting motor, and transmission motor to control their opening and closing; the control system is electrically connected to the lifting cylinder 23 and the clamping cylinder 25 to control their movement to adjust the position of the positioning component 2 and adjust the clamping unit to clamp and fix the pipe 5; the distance sensor 47 is electrically connected to the control system to transmit detection data to the control system, and the control system analyzes the detection data and adjusts the positioning component 2, the positioning conveying component 3, and the clamping component 4 based on the analysis results.

[0039] The operating procedure and working principle of this device are as follows:

[0040] Move the auxiliary device to the end of the fixed pipe 5 and the docking pipe 6 to be installed, and adjust the lifting base 1 to drive the positioning component 2 and the positioning conveying component 3 to rise and fall to a suitable position. At this time, the end of the fixed pipe 5 is located in the clamping unit of the positioning component 2.

[0041] The docking pipe 6 is hoisted and moved onto the roller 32. The worm gear mechanism 313 is adjusted so that the rotating seat 33 drives the docking pipe 6 to rise or fall. At the same time, the distance sensor 47 detects the distance data between itself and the docking pipe 6. The height of the rotating seat 33 corresponding to the minimum data is obtained. The minimum data is the distance between itself and the diameter of the docking pipe 6 on the horizontal plane detected by the distance sensor 47. The rotating seat 33 is then adjusted to the height corresponding to the minimum data. The clamping unit is adjusted so that the clamping cylinder 25 drives the clamping plate 26 to move, so that the clamping plate 26 abuts against the outer wall of the end of the fixed pipe 5.

[0042] Rotating the first rotating rod 42 causes the second rotating rod 43 to rotate, which in turn causes the adjusting rod 44 to move along the limiting rod 411. At the same time, the two distance sensors 47 in each clamping assembly 4 detect the distance from the end wall of the docking pipe 6. If the data detected by the two distance sensors 47 in each clamping assembly 4 are not equal, the lead screw 37 is rotated, causing the guide block 35 to move, which in turn causes the rotating shaft 332, the rotating seat 33, and the components mounted on the rotating seat 33 to rotate until the data detected by the two distance sensors 47 are approximately the same. Then, rotating the first rotating rod 42 causes the positioning arc plate 45 to contact the wall of the docking pipe 6.

[0043] The drive roller 32 rotates, causing the docking pipe 6 to move closer to the fixed pipe 5 until the fixed pipe 5 contacts the end wall of the docking pipe 6, thus fixing the fixed pipe 5 and the docking pipe 6.
