Description

Technical Field

[0001] This utility model relates to the field of pipeline inspection technology, and in particular to a crawler frame for pipeline inspection. Background Technology

[0002] A pipeline inspection crawler frame typically refers to a mobile equipment frame used for inspecting the interior of pipelines. It carries inspection instruments (such as cameras and X-ray machines) and crawls automatically or manually inside the pipeline to inspect its internal condition. This crawler frame generally has a drive unit, positioning device, and necessary cables and control system, enabling it to move flexibly in confined pipeline spaces, recording defects such as deformation, cracks, and corrosion inside the pipeline, providing crucial data for quality evaluation of pipeline construction and maintenance repair.

[0003] In the existing technology, when using a crawler frame to inspect pipelines, the crawler frame needs to carry cables into the pipeline. The movement of the cables inside the pipeline is often limited by space and the complex environment. This causes the cables to rub against the pipeline wall, the crawler frame, or other obstacles during the dragging process, resulting in wear or even damage to the cable sheath. This, in turn, affects the normal use of the crawler frame. Utility Model Content

[0004] The main objective of this invention is to provide a crawler frame for pipeline inspection, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A crawler frame for pipeline inspection includes a crawler frame body. A detection camera is mounted on the left side of the crawler frame body, and a cable is mounted on the right side. An auxiliary mechanism is mounted on the top surface of the crawler frame body, comprising a fixed plate, a first guide wheel, a concave seat, a concave frame, a connecting shaft, a worm gear, and a second guide wheel. The concave seat is fixedly connected to the top surface of the crawler frame body, and the concave frame is movably connected to the concave seat via second rotating rods on both sides. A set of symmetrical fixed plates are fixedly connected to the right side walls of the concave frame and the crawler frame body, respectively. The first guide wheel is movably connected between the fixed plates via first rotating rods at both ends. The worm gear is fixedly connected to the outside of the connecting shaft at the lower part of the concave frame, and the worm gear is movably connected between symmetrical fixed blocks inside the concave seat via third rotating rods at both ends and meshes with the worm gear. A set of symmetrical second guide wheels is also movably connected to the upper part of the concave frame.

[0007] Preferably, a concave seat is fixedly installed on the right side of the top surface of the crawling frame, and a second rotating hole is provided on each of the two side walls of the concave seat. A set of symmetrical fixing blocks is fixedly installed on the inner bottom surface of the concave seat, and a third rotating hole is provided on the side wall of the fixing blocks.

[0008] Preferably, a third rotating rod is fixedly installed at each end of the worm gear, and the third rotating rod is movably installed in the third rotating hole, with a knob fixedly installed on the outer end of one end of the third rotating rod.

[0009] Preferably, the concave frame is in an inverted state, and a second rotating rod is fixedly installed on the bottom of each of the two side walls of the concave frame. The second rotating rod is movably installed in the second rotating hole. A connecting shaft is fixedly installed inside the lower part of the concave frame, and a worm gear is fixedly installed on the outer wall of the connecting shaft. The worm gear and the worm are meshed together.

[0010] Preferably, a set of symmetrical fixing plates are fixedly installed on the lower right side wall of the concave frame and on the right side wall of the crawling frame, and a first rotating hole is opened on the side wall of the fixing plate. A first rotating rod is fixedly installed on both ends of the first guide wheel, and the first rotating rod is movably installed in the first rotating hole.

[0011] Preferably, a set of symmetrical fourth rotating holes are respectively opened on the upper side walls of the inner side of the concave frame, and the second guide wheel is provided with a set of symmetrical upper and lower sides, and the two ends of the second guide wheel are respectively fixedly installed with fourth rotating rods and movably installed in the fourth rotating holes.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this utility model, the auxiliary mechanism includes a crawling frame. Before use, rotating the knob drives the worm gear to rotate via the third rotating rod. The worm gear, through rotational meshing, drives the worm wheel to rotate. The worm wheel, through the connecting shaft, drives the concave frame to rotate. The concave frame rotates on the concave seat via the second rotating rods on both sides until it changes from a folded horizontal state to an unfolded vertical state. The cable then passes through the groove between the upper and lower symmetrical second guide wheels, and then passes over the groove of the first guide wheel on the lower right side of the concave frame. Finally, the cable passes under the groove of the first guide wheel on the right side of the crawling frame and connects to the crawling frame body. This allows the crawling frame to support and elevate the cable during pipeline inspection. By elevating the cable support, wear and damage caused by dragging and friction can be avoided, and the cable can be protected. Furthermore, by adjusting the inclination of the concave frame, the cable support height can be adjusted according to the pipeline height, thus ensuring the normal use of the crawling frame.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1 - Figure 4 As shown, a crawler frame for pipeline inspection includes a crawler frame body 1. A detection camera 2 is located on the left side of the crawler frame body 1, and a cable 3 is located on the right side. An auxiliary mechanism 4 is located on the top surface of the crawler frame body 1. The auxiliary mechanism 4 includes a fixing plate 5, a first guide wheel 7, a concave seat 9, a concave frame 13, a connecting shaft 15, a worm gear 17, and a second guide wheel 21. The concave seat 9 is fixedly connected to the top surface of the crawler frame body 1, and the concave frame 13 is movably connected to the concave seat 9 via second rotating rods 14 on both sides. A set of symmetrical fixed plates 5 are fixedly connected to the right side wall of the concave frame 13 and the crawling frame 1, respectively. The first guide wheel 7 is movably connected between the fixed plates 5 through the first rotating rods 8 at both ends. The worm gear 16 is fixedly connected to the outside of the connecting shaft 15 at the lower inside of the concave frame 13. The worm 17 is movably connected between the symmetrical fixed blocks 11 in the concave seat 9 through the third rotating rods 18 at both ends and meshes with the worm gear 16. A set of symmetrical second guide wheels 21 is also movably connected to the upper inside of the concave frame 13.

[0021] like Figure 4As shown, a concave seat 9 is fixedly installed on the right side of the top surface of the crawler frame 1, and a second rotating hole 10 is provided on each of the two side walls of the concave seat 9. The second rotating hole 10 is used to cooperate with the second rotating rod 14 to realize the rotation operation. A set of symmetrical fixing blocks 11 is fixedly installed on the inner bottom surface of the concave seat 9, and a third rotating hole 12 is provided on the side wall of the fixing block 11. The third rotating hole 12 is used to cooperate with the worm gear 17 to realize the rotation operation.

[0022] like Figure 4 As shown, a third rotating rod 18 is fixedly installed at both ends of the worm gear 17, and the third rotating rod 18 is movably installed in the third rotating hole 12. A knob 19 is fixedly installed on the outer end of one end of the third rotating rod 18. After rotating the knob 19, the worm gear 17 is rotated through the third rotating rod 18, and the inclination of the concave frame 13 can be adjusted.

[0023] like Figure 4 As shown, the concave frame 13 is in an inverted state, and second rotating rods 14 are fixedly installed on the bottom of the two side walls of the concave frame 13. The second rotating rods 14 are movably installed in the second rotating holes 10. A connecting shaft 15 is fixedly installed inside the lower part of the concave frame 13, and a worm gear 16 is fixedly installed on the outer wall of the connecting shaft 15. The worm gear 16 and the worm 17 mesh together. When the worm gear 16 rotates under the rotational meshing action of the worm 17, it will drive the concave frame 13 to rotate through the connecting shaft 15, so that the second rotating rods 14 on both sides of the concave frame 13 rotate in the second rotating holes 10, so that the concave frame 13 unfolds from the horizontal state to the vertical state, and the concave frame 13 adjusts the height of the cable 3 during this change, so as to adapt to different pipe heights.

[0024] like Figure 3 and 4 As shown, a set of symmetrical fixing plates 5 are fixedly installed on the lower right side wall of the concave frame 13 and on the right side wall of the crawling frame 1, respectively. The fixing plates 5 have a first rotating hole 6 on their side walls. The two ends of the first guide wheel 7 are fixedly installed with a first rotating rod 8, and the first rotating rod 8 is movably installed in the first rotating hole 6. After the cable 3 passes through the upper groove of the upper first guide wheel 7 and then passes through the lower groove of the lower first guide wheel 7, it can guide the cable 3 and prevent the cable 3 from contacting the crawling frame 1 and getting tangled.

[0025] like Figure 4As shown, a set of symmetrical fourth rotating holes 20 are respectively opened on the upper side walls of the inner side walls of the concave frame 13. The second guide wheel 21 is provided with a set of symmetrical upper and lower sides, and the two ends of the second guide wheel 21 are respectively fixedly installed with fourth rotating rods 22 and movably installed in the fourth rotating holes 20. After the cable 3 passes through the groove between the second guide wheels 21, the concave frame 13 can lift the cable 3 after tilting, preventing the cable 3 from contacting the bottom surface and causing dragging friction and wear damage.

[0026] The specific operating principle of auxiliary mechanism 4 in conjunction with the pipeline inspection crawler is as follows:

[0027] Before use, rotating knob 19 causes the third rotating rods 18 at both ends of worm 17 to rotate through the third rotating holes 12 on the side walls of the symmetrical fixed blocks 11. The third rotating rods 18 will cause worm 17 to rotate between the fixed blocks 11, so that worm 17 will drive worm wheel 16 to rotate under the action of rotational meshing. During the rotation of worm wheel 16, it will drive concave frame 13 to rotate through connecting shaft 15. When concave frame 13 rotates, the second rotating rods 14 installed on the lower side walls of both sides will rotate on both sides of the concave seat 9 installed on the right side of the top surface of the crawler frame body 1. The concave frame 13 is rotated within the second rotating hole 10 on the wall, causing it to change from a horizontal to a vertical position until it is adjusted to a suitable inclination according to the height of the pipe. Then, the cable for connecting the crawler frame 1 is passed from the right side of the concave frame 13, through the groove between the upper and lower symmetrical second guide wheels 21 inside the concave frame 13. After passing through, the cable 3 is wound around to the right side from below the lower second guide wheel 21, and then passes between the symmetrical fixing plates 5 installed on the lower right side of the concave frame 13. The cable 3 passes through the upper groove of the first guide wheel 7, and then is pulled downwards while keeping it close to the right side of the groove of the upper first guide wheel 7. After the cable 3 passes close to the right side groove of the lower first guide wheel 7, it is connected to the crawling frame 1. When the crawling frame crawls along the pipe and drags the cable 3, the first guide wheel 7 will rotate and the first rotating rods 8 at both ends will rotate in the first rotating holes 6 opened on the side wall of the fixed plate 5. The second guide wheel 21 will also rotate and the fourth rotating rods 22 at both ends will rotate in the fourth rotating holes 2 opened on the upper side walls of the concave frame 13. The internal rotation of the crawler frame allows it to support and elevate the cable 3 during pipeline inspection. This elevation prevents wear and damage caused by dragging and friction, and provides auxiliary protection for the cable 3, thus ensuring the normal operation of the crawler frame. Finally, as the crawler frame 1 crawls inside the pipeline, the inspection camera 2 records defects such as deformation, cracks, and corrosion inside the pipeline and transmits the signals to the terminal equipment via the cable 3 to complete the pipeline inspection operation.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
