Description

Technical Field

[0001] The utility model relates to the field of cable maintenance, in particular to an auxiliary moving mechanism for detecting faults in underground cable channels. Background Art

[0002] Underground cables refer to cables buried underground and are widely used in fields such as electricity and communication. The fault detection of underground cable channels is an important link to ensure the normal operation of infrastructure such as electricity and communication. Some existing traditional maintenance steps require manual inspection of cables through equipment to screen out fault locations. However, the cables are generally quite long, and it is labor-consuming for workers to carry maintenance equipment to inspect the cables. Therefore, an auxiliary moving mechanism is needed to carry the maintenance equipment to move and inspect the cables, so as to reduce manual input and improve the maintenance efficiency.

[0003] After retrieval, Chinese Patent Publication No.: CN219997214U discloses a cable fault detection device, which relates to the field of cable detection technology and includes a bottom plate. At both ends near the top of the bottom plate, arc-shaped blocks are fixedly arranged. Between the two arc-shaped blocks, there are two U-shaped plates. At the center of one side wall of each arc-shaped block, a first circular groove is opened. Inside the first circular groove, a first spring is embedded and fixed. The other end of the first spring is fixedly connected to one side wall of the U-shaped plate. Inside the U-shaped plate and near the ends, there are clamping plates, and second springs are fixedly arranged on one side wall of each clamping plate. In the utility model, by placing the cable between the two clamping plates on both sides, and then driving the detection rollers to rotate through the driving motor, the effect of making the detection device move along the cable can be achieved, so that the effect of not requiring electricians to climb to high places to gradually maintain the cable can be achieved, and at the same time, the effect of maintaining the entire length of the longer cable can be achieved, which is both convenient and practical.

[0004] Although the above device can make the detection device move along the cable by placing the cable between the two clamping plates on both sides and then driving the detection rollers to rotate through the driving motor, due to the relatively flat upper parts of the clamping plates and the rollers, the cable cannot be directly clamped between the two rollers. Workers need to first pull the two clamping plates apart and then clamp the cable between the two rollers. And the mechanism does not have a structure for pulling the two clamping plates, which makes the above operation inconvenient and not very practical. Therefore, an auxiliary moving mechanism for detecting faults in underground cable channels is proposed to solve the above problems. Content of the Utility Model

The upper part of the auxiliary component 8 is provided with a lower roller 9 for assisting in the movement of the mechanism.

[0035] As Figures 3 - 4 shown, a mounting block 11 is penetrated and rotatably connected to the left side of the upper housing 1 for cooperating with the installation of the mounting rod 2. An auxiliary opening 12 is formed in the middle of the mounting block 11, and its shape is adapted to the mounting rod 2 and the limiting strip 21. The mounting rod 2 and the limiting strip 21 are movably connected thereto. Limiting strips 21 are fixedly connected to the upper and lower parts of the left side of the outer wall of the mounting rod 2 for cooperating with driving the mounting block 11 to rotate, and it can also limit the position of the upper roller 3 to a certain extent. Clamping strips 22 are fixedly connected to the upper and lower parts of the middle of the outer wall of the mounting rod 2 for cooperating with connecting the upper roller 3, so that the mounting rod 2 can drive the upper roller 3 to rotate. A connection opening 31 is formed in the middle of the upper roller 3, and its shape is adapted to the mounting rod 2 and the clamping strip 22. The mounting rod 2 and the clamping strip 22 are movably connected thereto. The power component further includes a rotating shaft 41 for connecting with the motor 4 to drive the fixed pipe 42 to rotate. The rotating shaft 41 is fixedly connected to the output end of the motor 4. The rotating shaft 41 penetrates the upper housing 1 and is rotatably connected thereto. The left end of the rotating shaft 41 is fixedly connected to a fixed pipe 42 for connecting the mounting rod 2, and it can also limit the movement position of the upper roller 3.

[0036] Further, the upper clamping member 5 includes a first mounting plate 51, the middle of which is fixed to the upper housing 1 by bolts. Both the front and rear parts of the top surface of the first mounting plate 51 are fixedly connected with first sliding blocks 52, which are used to cooperate with the connection between the first mounting plate 51 and the upper housing 1. The first sliding blocks 52 are movably connected with the upper housing 1. Both the front and rear parts of the bottom surface of the first mounting plate 51 are fixedly connected with clamping blocks 53, which are used to cooperate with the connection with the lower clamping member 6. The lower clamping member 6 includes a second mounting plate 61, the middle of which is fixed to the lower housing 7 by bolts. Both the front and rear parts of the bottom surface of the second mounting plate 61 are fixedly connected with second sliding blocks 62, which are used to connect with the lower housing 7. The second sliding blocks 62 are movably connected with the lower housing 7. Both the front and rear parts of the top surface of the second mounting plate 61 are fixedly connected with clamping sleeves 63, which have a certain deformation ability and are used to connect the clamping blocks 53, and the clamping blocks 53 are clamped with them.

[0037] As Figure 5 shown, the auxiliary component 8 includes a housing 81, which is used to connect each component. The housing 81 is fixedly connected with the lower housing 7. The inner wall of the housing 81 is slidably connected with a mounting seat 82, which is used to cooperate with the fixation of the connecting rod 83. Both the left and right sides of the upper part of the mounting seat 82 are fixedly connected with connecting rods 83, and the end close to the lower roller 9 is spherical. There are two first springs 84 fixedly connected between the mounting seat 82 and the housing 81, which are used to cooperate with the movement and reset of the mounting seat 82. Both the left and right sides of the middle part of the lower roller 9 are provided with mounting grooves 91, which are used to cooperate with the connection of the connecting rods 83. The inner wall of the mounting groove 91 is slidably connected with a limiting block 92, and a groove adapted to the spherical ball is provided on the side of the limiting block 92 close to the connecting rod 83 to cooperate with the connection of the connecting rod 83, so that the lower roller 9 can be installed on the auxiliary component 8. The limiting block 92 is movably connected with the connecting rod 83. A second spring 93 is fixedly connected between the limiting block 92 and the mounting groove 91, which is used to cooperate with the movement of the limiting block 92 to cooperate with the limiting block 92 to tightly hold and fix the connecting rod 83, thus completing the installation and disassembly of the lower roller 9.

[0038] Working principle: When in use, place the upper housing 1 together with the components connected thereto on the upper part of the cable to be detected, and then place the lower housing 7 together with the components connected thereto on the lower part of the cable to be detected. Then press the lower housing 7 towards the upper housing 1, so that the clamping block 53 is snapped into the clamping sleeve 63, fixing the upper clamping member 5 and the lower clamping member 6, and thus fixing the upper housing 1 and the lower housing 7. When the upper housing 1 and the lower housing 7 are fixed, according to the size of the cable, it will push the lower roller 9 downward, and the mounting seat 82 connected thereto through the connecting rod 83 will move towards the housing 81, and will squeeze the first spring 84 in the housing 81. The first spring 84 will generate a reaction force and push the mounting seat 82 upward, so that the upper roller 3 and the lower roller 9 will press against the upper and lower sides of the cable. Then turn on the motor 4, and the motor 4 will drive the rotating shaft 41 to rotate. The rotating shaft 41 will drive the fixed tube 42 to rotate. The mounting rod 2 fixed to the fixed tube 42 will rotate accordingly. The limiting strip 21 and the clamping strip 22 outside the mounting rod 2 will rotate accordingly, thereby driving the connected upper roller 3 and the mounting block 11 to rotate. When the upper roller 3 rotates, since it is in close contact with the cable surface, it will move along the cable, thereby driving the overall mechanism to move. When the overall mechanism moves, turn on the detection device to detect the cable. When the detection is completed and the mechanism needs to be removed, just pull the upper housing 1 upward and the lower housing 7 downward respectively, so that they drive the upper clamping member 5 and the lower clamping member 6 to move upward and downward respectively, so that the clamping block 53 is separated from the clamping sleeve 63.

[0039] When the upper clamping member 5, the lower clamping member 6, or the upper roller 3, the lower roller 9 are worn due to long-term use, affecting the normal operation of the mechanism and need to be replaced, first loosen the bolts fixing the upper clamping member 5 or the lower clamping member 6 to the upper housing 1 or the lower housing 7, and then push the upper clamping member 5 or the lower clamping member 6 forward or backward to separate its first slider 52 or second slider 62 from the upper housing 1 or the lower housing 7. Then install the first slider 52 or second slider 62 on the new upper clamping member 5 or lower clamping member 6 into the upper housing 1 or the lower housing 7 again, and then fix it to the housing with bolts.

[0040] When the upper roller 3 needs to be replaced, one hand fixes the fixed pipe 42, and then the other hand rotates the mounting rod 2 to disengage it from the fixed pipe 42. Then, the mounting rod 2 is pulled out of the upper housing 1 to separate it from the upper roller 3. Then, a new upper roller 3 is placed between the mounting block 11 and the fixed pipe 42. Next, the mounting rod 2 is passed through the mounting block 11 and then through the connection port 31 in the middle of the new upper roller 3. Finally, the mounting rod 2 is tightened with the fixed pipe 42. When the lower roller 9 needs to be replaced, first move the lower roller 9 in the direction of the connecting rod 83 on one side. The connecting rod 83 on this side will push the limiting block 92 on this side in the direction of the second spring 93. At the same time, the connecting rod 83 on the other side will disengage from the limiting block 92 and the mounting groove 91 on the other side. Then, the lower roller 9 is gently pulled upwards at an angle to make the connecting rod 83 on this side disengage from the mounting groove 91 on this side. When installing the lower roller 9, first, insert the connecting rod 83 on one side into the mounting groove 91 on one side of the new lower roller 9. Then, push the lower roller 9 towards the connecting rod 83 on this side again to leave a certain gap between the other side of the lower roller 9 and the connecting rod 83 on the other side. Align the mounting groove 91 on the other side with the connecting rod 83 on the other side, and then release the force applied to the connecting rod 83 on this side. The second spring 93 will push the limiting block 92 to reset. At this time, the connecting rod 83 on the other side will be stuck in the groove of the limiting block 92 in the mounting groove 91 on the other side, and the installation of the lower roller 9 is completed immediately.

[0041] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
