[0030] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0031] Embodiment 1:

[0032] The present invention provides a C-type opening and closing tool track locking and positioning device for deep-sea pipeline repair, referring to Figures 1 to 7 As shown, the track locking and positioning device of the C-type opening and closing tool for deep-sea pipeline repair includes a track positioning mechanism 1, and the track positioning mechanism 1 includes a plurality of outer rolling assemblies 11.

[0033] All the outer rolling assemblies 11 are evenly spaced along the circumference of the base assembly 3 of the C-type opening and closing machine; all the outer rolling assemblies 11 are arranged around the outside of the track assembly 4 of the C-type opening and closing machine, and the outer rolling assemblies 11 are in rolling cooperation with the outer peripheral wall of the track assembly 4.

[0034] When the track assembly 4 rotates along the base assembly 3 , the outer rolling assemblies 11 evenly spaced along the circumferential direction form an outer ring positioning for the track assembly 4 , which can effectively improve the positioning effect.

[0035] Rolling friction is formed between the outer peripheral wall of the track assembly 4 and the outer rolling assembly 11, the friction resistance is small, and the rotation process of the track assembly 4 is stable and smooth.

[0036] Embodiment 2:

[0037] Example 2 is based on Example 1:

[0038] like Figures 1 to 7 As shown, the outer rolling assembly 11 includes an outer support frame 112 and an outer unit rolling element 111 .

[0039] The outer support frame 112 is fixedly disposed on the outer wall of the base assembly 3 ; the outer unit rolling element 111 is rotatably disposed on the outer support frame 112 and rollingly cooperates with the outer peripheral wall of the track assembly 4 .

[0040] Specifically, the outer support frame 112 is configured as a support block, which is provided with a mounting hole, and the threaded fastener passes through the mounting hole, so that the support frame 112 is installed on the outer peripheral wall of the base assembly 3. In this way, it is easy to disassemble and assemble while ensuring firm support.

[0041] As an optional embodiment, the outer peripheral wall of the base assembly 3 is evenly spaced along the circumferential direction to form a plurality of clearance grooves 311 , and all the clearance grooves 311 correspond to all the outer unit rolling elements 111 one by one.

[0042] At least a partial section of the outer unit rolling element 111 passes through the clearance groove 311 and rolls with the outer peripheral wall of the track assembly 4; the width of the clearance groove 311 is greater than the axial length of the outer unit rolling element 111, and the length of the clearance groove 311 is greater than the diameter of the outer unit rolling element 111, which can effectively make way for the outer unit rolling element 111, and make the structure more compact while ensuring the positioning effect of the outer rolling assembly 11 on the outer ring of the track assembly 4.

[0043] As an optional embodiment, the track positioning mechanism 1 includes a plurality of inner rolling assemblies 12, and all inner rolling assemblies 12 are evenly spaced along the circumference of the base assembly 3 of the C-type opening and closing machine; the inner rolling assembly 12 is disposed on the inner side of the track assembly 4 of the C-type opening and closing machine, and is in rolling cooperation with the inner circumferential wall of the track assembly 4.

[0044] During the rotation of the track assembly 4 along the base assembly 3, the inner rolling assembly 12 evenly spaced along the circumferential direction forms an inner ring positioning for the track assembly 4, which cooperates with the outer rolling assembly 11 to achieve double positioning inside and outside, with significant positioning effect, and can prevent the problem of inaccurate positioning when the existing track assembly 4 is closed. At the same time, rolling friction is adopted, and the friction resistance is small.

[0045] As an optional embodiment, the inner rolling assembly 12 includes an inner unit rolling member 121 , which is rotatably disposed on the base assembly 3 and is located on the inner side of the track assembly 4 .

[0046] The inner peripheral wall of the track assembly 4 is provided with a guide groove 411 , the size of which matches that of the inner unit rolling element 121 , and the guide groove 411 has a guiding function, so that the inner unit rolling element 121 rotates along a fixed track.

[0047] As an optional implementation, the outer unit rolling element 111 is configured as a first pulley, and the first pulley is rotatably disposed on the support frame 112 via a first mounting shaft.

[0048] The inner unit rolling element 121 is configured as a second pulley, and the second pulley is rotatably disposed on the base assembly 3 via a second mounting shaft.

[0049] As an optional embodiment, the C-type opening and closing unit track locking and positioning device for deep-sea pipeline repair also includes a track locking mechanism 2, the base assembly 3 includes two relatively connected C-type bases 31, and the track assembly 4 includes two relatively connected C-type tracks 41.

[0050] The existing external card split rotary pipeline repairing machine has a technical defect that its C-shaped track slides out of its corresponding C-shaped machine base when it is separated. The setting of the track locking mechanism 2 is intended to solve this technical defect.

[0051] When the two C-shaped bases 31 are separated, the track locking mechanism 2 stably locks the C-shaped track 41 to the corresponding C-shaped base 31 .

[0052] When the two C-shaped machine bases 31 are closed and connected, the track locking mechanism 2 releases the locking effect on the C-shaped track 41, and then the track assembly 4 can rotate along the machine base assembly 3 without hindrance.

[0053] As an optional implementation, the track locking mechanism 2 includes a plug-in assembly 21 and an insert 22 , the plug-in assembly 21 is disposed on the C-shaped base 31 , and the insert 22 is fixedly disposed on the C-shaped track 41 .

[0054] When the two C-shaped bases 31 are separated, the plug-in assembly 21 is plugged into the corresponding plug-in member 22, thereby locking the C-shaped rail 41 to the corresponding C-shaped base 31. In this way, the C-shaped rail 41 can be effectively prevented from sliding out of the C-shaped base 31 when the machines are separated.

[0055] When the two C-shaped bases 31 are connected, the plug-in assembly 21 is separated from the corresponding plug-in member 22 , and then the track assembly 4 can rotate along the base assembly 3 to ensure that the track assembly 4 runs along the base assembly 3 without hindrance.

[0056] The plug-in assembly 21 and the plug-in member 22 cooperate with each other to achieve locking and unlocking with a plug-in structure, which has a simple structure and significant effect.

[0057] As an optional implementation, the plug-in assembly 21 includes a fixing seat 211 , a guide connection member 212 , a plug-in member 213 and an elastic member 214 .

[0058] The fixed seat 211 and the guide connecting member 212 are respectively fixedly set at the corresponding ends of the two C-shaped machine bases 31. Specifically, the two C-shaped machine bases 31 are respectively the first C-shaped machine base and the second C-shaped machine base, and a corresponding set of opening ends of the two are respectively the first opening end and the second opening end. The fixed seat 211 is fixedly set at the first opening end, and the guide connecting member 212 is fixedly set at the second opening end and corresponds to the fixed seat 211.

[0059] The fixing seat 211 includes a base fixedly disposed on the first open end and a limiting sleeve fixedly disposed on the base, and the limiting sleeve is adapted to the plug-in component 213 .

[0060] The guide connector 212 includes a connector base fixedly disposed on the second open end and a connector block integrally disposed on the connector base. A groove matching the connector 213 is disposed on the side of the connector block facing the connector 213, and a guide portion is disposed on the bottom side of the connector block.

[0061] The plug connector 213 is a latch pin, which is disposed in the limiting sleeve and can move along the axial direction of the limiting sleeve. A guide block 215 is fixedly disposed on the latch pin.

[0062] The elastic member 214 is a spring, which is sleeved on the latch. The spring is located below the guide block 215, and two ends of the spring are respectively against the inner bottom wall of the limiting sleeve and the guide block 215.

[0063] In the initial state, the connector 213 is located in the groove of the guide connector 212, and the guide block 215 abuts against the guide connector 212 to limit the connector 213 and make it disengaged from the plug-in component 22. At this time, the connector 213 squeezes the elastic member 214 to put it in a compressed deformation state, and the track assembly 4 can rotate along the base assembly 3 without hindrance.

[0064] When the machine is separated, the two C-shaped machine bases 31 are separated, and the guide block 215 is separated from the guide connector 212. At this time, the limiting effect of the guide connector 212 on the plug-in component 213 is released, and the elastic member 214 in compression deformation releases its elastic force, pushing the plug-in component 213 to plug into the plug-in component 22, thereby locking the C-shaped track 41 to the corresponding C-shaped machine base 31; when the machine is closed, the two C-shaped machine bases 31 are connected, and the guide block 215 moves along the guide portion, causing the plug-in component 213 to move away from the plug-in component 22 until the guide block 215 abuts against the guide connector 212. At this time, the plug-in component 213 squeezes the elastic member 214 and is completely separated from the corresponding plug-in component 22, and the track positioning mechanism 1 returns to its initial state.

[0065] As an optional implementation, a first guide slope 2121 is provided on the guide block 215, and the guide portion is provided as a second guide slope 2151. The first guide slope 2121 is adapted to the second guide slope 2151, and the limiting and guiding effect is significant.

[0066] Specifically, the first guide slope 2121 and the second guide slope 2151 are configured as inclined surfaces. Further, the first guide slope 2121 is an inwardly concave arc-shaped inclined surface, and the second guide slope 2151 is an outwardly convex arc-shaped inclined surface.
