All other embodiments obtained by those skilled in the art without creative work on the basis of the embodiments of the present application shall belong to the protection scope of the present application.

[0038] For the convenience of description, the coordinate system is defined as Figure 1 As shown, the left-right direction is the horizontal direction, the front-back direction is the longitudinal direction, and the up-down direction is the vertical direction.

[0039] Embodiment 1

[0040] like Figure 1 and Figure 2As shown, a pipeline diameter measurement and pigging integrated device includes a main frame, and the main frame includes a central housing 11 and connecting plates 12 located at the front and rear sides of the central housing 11. A lead screw 131 is rotatably arranged between the central housing 11 and the connecting plate 12, and a first driving component for driving the two lead screws 131 to rotate is arranged in the central housing 11. At least two guide rods 14 are arranged between the central housing 11 and the connecting plate 12, and a slide plate 15 that can slide forward and backward along the guide rod 14 is respectively arranged at the front and rear sides of the central housing 11. The slide plate 15 is provided with guide holes that match the guide rods 14, and the number of the guide holes is the same as the number of the guide rods 14, and they correspond one to one. The guide rods 14 are inserted into the corresponding guide holes and match the corresponding guide holes to achieve a guiding effect. A nut 132 that matches the lead screw 131 is fixedly arranged on the slide plate 15 in a detachable manner. When the first driving component drives the two lead screws 131 to rotate, the two slide plates 15 can move toward or away from each other along the guide rod 14 under the driving action of the nut 132 .

[0041] Preferably, a plurality of guide rods 14 located on the front side of the center shell 11 are evenly arranged in the circumferential direction around the screw 131 located on the front side of the center shell 11; a plurality of guide rods 14 located on the rear side of the center shell 11 are evenly arranged in the circumferential direction around the screw 131 located on the rear side of the center shell 11.

[0042] As a specific implementation, in this embodiment, the lead screws 131 located at the front and rear sides of the central housing 11 are coaxially arranged. Three guide rods 14 are arranged between the central housing 11 and the connecting plate 12, and the guide rods 14 located at the front and rear sides of the central housing 11 are aligned one by one, and the two aligned guide rods 14 are coaxially arranged.

[0043] As a specific implementation method, Figure 4 and Figure 5 As shown, in this embodiment, the two guide rods 14 located on both sides of the central housing 11 and aligned are made of the same cylindrical rod. That is, three cylindrical rods are evenly distributed along the circumferential direction around the two coaxially arranged lead screws 131 on the central housing 11, and mounting holes for accommodating the cylindrical rods are provided on the central housing 11. The two ends of the cylindrical rods extend to the outside of the central housing 11 respectively, and are fixedly connected to the connecting plate 12 in a detachable manner. Exemplarily, the connecting plate 12 is a triangular structure, and the ends of the three cylindrical rods are fixedly connected to the three corners of the connecting plate 12 respectively. In this way, the central housing 11, the connecting plate 12 and the guide rods 14 can form a rigid whole with good structural strength.

[0044] As a specific implementation method, Figure 2 and Figure 3 As shown, the slide plate 15 described in this embodiment is in a triangular structure, and guide holes matching with the guide rods 14 are respectively provided on the three corners of the slide plate 15 .

[0045] like Figure 1 , Figure 5 , Figure 7 and Fig. 9 As shown, the first driving component includes a first motor 171 fixedly arranged in the center housing 11 in a detachable manner, and the power output shaft of the first motor 171 passes through the side wall of the center housing 11 and extends to the outside of the center housing 11. The outer ends of the two lead screws 131 (the end facing away from the center housing 11 is the outer end) are rotatably connected to the connecting plate 12 through the bearing assembly 16, wherein the inner end of one of the lead screws 131 (the end facing the center housing 11 is the inner end) is connected to the power output shaft of the first motor 171, and the inner end of the other lead screw 131 (the end facing the center housing 11 is the inner end) is rotatably connected to the center housing 11 through the bearing assembly 16. A transmission shaft 172 arranged parallel to the lead screw 131 is rotatably arranged on the center housing 11, and the two ends of the transmission shaft 172 pass through the center housing 11 and extend to the outside of the center housing 11. The lead screws 131 on both sides of the central housing 11 are connected to the transmission shaft 172 through a transmission mechanism. Under the power transmission of the transmission shaft 172 and the transmission mechanism, the power output by the first motor 171 can be transmitted to the two lead screws 131 at the same time, thereby driving the lead screws 131 to rotate together.

[0046] As a specific implementation, the transmission mechanism described in this embodiment adopts gear transmission. The power output shaft of the first motor 171 is connected to one of the lead screws 131 through the first gear 173, and the end of the transmission shaft 172 facing the same direction as the power output shaft of the first motor 171 is provided with a second gear 174 meshing with the first gear 173. The end of the transmission shaft 172 facing the opposite direction to the power output shaft of the first motor 171 is provided with a third gear 175, and the other lead screw 131 is provided with a fourth gear 176 meshing with the third gear 175. Exemplarily, the first gear 173 includes a gear body and a gear shaft, and the gear shaft is provided with an axial hole that penetrates the gear shaft in the axial direction. The power output shaft of the first motor 171 and the lead screw 131 are respectively inserted into the axial hole from both ends and connected with the first gear 173. Here, the first gear 173 not only plays the role of a transmission member, but also plays the role of a connecting member as a coupling.

[0047] As a specific implementation method, Figure 6 , Figure 8 and Fig.11 As shown, the central housing 11 described in this embodiment includes a main housing 111, and the main housing 111 is provided with a mounting through hole that penetrates the main housing 111 in a direction parallel to the lead screw 131. The two ends of the main housing 111 are respectively provided with end covers 112, and the end covers 112 and the main housing 111 together form a mounting cavity for accommodating the first motor 171. The transmission shaft 172 is located in the mounting through hole, and the two ends of the transmission shaft 172 are rotatably connected to the end covers 112 through bearing assemblies 16.

[0048] like Figure 2 and Figure 3 As shown, at least three running parts 2 are respectively disposed at the front and rear ends of the central housing 11. As a specific implementation, in this embodiment, three running parts 2 are respectively disposed at the front and rear ends of the central housing 11.

[0049] The walking component 2 includes a first support arm 21, one end of which is hinged to the central housing 11 through a first hinge shaft 22, and an active walking component 23 is arranged at the other end of the first support arm 21. A connecting rod 24 is arranged between the first support arm 21 and the slide plate 15 on the same side, one end of which is hinged to the slide plate 15 through a second hinge shaft 25, and the other end of which is hinged to an ear plate 211 arranged at the middle of the first support arm 21 through a third hinge shaft 26. When the two slide plates 15 move toward each other under the driving action of the first driving component, the walking component 2 is dispersed and opened, thereby pressing against the inner wall of the pipe; when the two slide plates 15 move in opposite directions under the driving action of the first driving component, the walking component 2 is retracted and closed, and the active walking component 23 of the walking component 2 is separated from the inner wall of the pipe, so that the whole device can be easily taken out of the pipe.

[0050] Exemplarily, the inner end of the first support arm 21 is hinged to the end cover 112 via a first hinge shaft 22 .

[0051] Driving the walking component 2 to open or close by the first driving component can adapt to different pipe diameters. At the same time, the output power of the first motor 171 can be controlled to control the pressing force of the active walking component 23 on the inner wall of the pipe, thereby obtaining a suitable friction force to ensure that the entire device can reliably move along the pipe wall.

[0052] Mounting plates 212 are respectively provided on both sides of the suspended end of the first support arm 21, and the active travel component 23 is located between the two mounting plates 212.
