Description

Technical Field

[0001] This invention relates to the field of fault location instruments, and in particular to equipment lifting devices and high-voltage cable fault location instruments. Background Technology

[0002] Cables are typically made up of several or groups of conductors twisted together, with each group of conductors insulated from the others. Cables are characterized by internal conductivity and external insulation. Cables are generally quite long during use, and locating faults in cables can save repair time. Currently, cable fault locators are commonly used to locate cable faults.

[0003] Currently, when workers need to use cable fault location devices to inspect cables and determine the location of faults, they must manually carry the device to a height for operation. For example, a strap is installed on the outside of the cable fault location device's casing, and the worker carries the entire device to a height using the strap. This wastes the worker's physical strength to some extent, and manually carrying the device to a height increases the risk of the device falling from a height due to the worker losing their grip. This not only damages the cable fault location device but also poses a significant safety hazard to the worker. Summary of the Invention

[0004] Therefore, it is necessary to provide an equipment lifting device and a high-voltage cable fault location device to address the problems of existing cable fault location devices requiring manual carrying to high altitudes, which wastes the physical strength of operators and easily causes safety hazards.

[0005] A device lifting system includes a housing, on which a lifting mechanism is provided, the lifting mechanism comprising:

[0006] Fasteners;

[0007] A rope retrieval assembly, the rope retrieval assembly being connected to the housing; and

[0008] At least one rope, one end of which is connected to the fixing member and the other end of which is connected to the rope recovery assembly, and the container can be lifted by winding the rope into the rope recovery assembly.

[0009] In one embodiment, the rope recovery assembly includes:

[0010] A connecting component, which is connected to the top surface of the housing;

[0011] A winding roller, which is rotatably connected to the connecting assembly;

[0012] A drive motor is mounted on the connecting assembly and is driven to one end of the winding roller.

[0013] In one embodiment, the connecting assembly includes two spaced-apart support blocks, and the two ends of the winding roller are rotatably connected to the two support blocks respectively.

[0014] In one embodiment, each of the support blocks has a receiving groove on the top of the side facing the other support block, the receiving groove being used to place the end of the fastener.

[0015] In one embodiment, the winding roller is provided with a partition plate that divides the winding roller into two sub-winding segments located on both sides of the partition plate;

[0016] The fastener is connected to two ropes, and the two ropes are connected to the two sub-winding segments one by one.

[0017] In one embodiment, the box includes a box body with an opening at the top and a cover plate disposed at the opening. The cover plate is detachably connected to the box body, and the lifting mechanism is disposed on the cover plate.

[0018] In one embodiment, a limiting member is slidably connected to one side plate of the box body, one end of the cover plate is rotatably connected to the limiting member, and the other end of the cover plate is engaged with the box body.

[0019] In one embodiment, both ends of the limiting member are provided with connecting plates, and a fixing knob is threadedly connected to the connecting plate, and the fixing knob is connected to the box body.

[0020] In one embodiment, a sliding groove is provided on the side plate, the sliding groove including a vertical section and a horizontal section communicating with the vertical section, the horizontal section being located at the top of the side plate, and the vertical section being located on the outer side wall of the side plate;

[0021] The limiting member is rotatably connected to a slider. When the end of the cover plate away from the limiting member is engaged with the box body, the slider is slidably connected within the horizontal section. When the end of the cover plate away from the limiting member is not engaged with the box body, the slider is slidably connected within the vertical section.

[0022] A high-voltage cable fault locator, comprising a fault locator body and an equipment lifting device as described above, wherein the fault locator body is disposed within the housing.

[0023] The aforementioned equipment lifting device, by fixing the fixing component at a certain height and then operating the rope recovery component to wind up the rope, lifts the box to the preset height. This avoids consuming the physical strength of the operators and also prevents the box from falling due to the operator not holding it firmly when manually lifting it, thereby reducing the safety hazards when lifting the box.

[0038] Please see Figure 1 and Figure 2 This invention provides a high-voltage cable fault locator 100, which is used to locate the fault location in a cable when a fault occurs, thereby saving repair time. The high-voltage cable fault locator 100 includes a locator body 300 and a lifting device 200. The lifting device 200 includes a housing 10, within which the locator body 300 is housed. Since cables are typically at a certain height above the ground, the lifting device 200 is used to lift the locator body 300 to a certain height to facilitate operation of the locator body 300 and to locate the fault location on the cable.

[0039] A lifting mechanism 20 is provided on the top surface of the housing 10. The lifting mechanism 20 includes a fixing member 21, a rope retrieval assembly 22 and at least one rope 23. The rope retrieval assembly 22 is connected to the top surface of the housing 10. One end of the rope 23 is connected to the rope retrieval assembly 22 and the other end is connected to the fixing member 21. The rope retrieval assembly 22 is used to wind up the rope 23.

[0040] It is understandable that when the container 10 needs to be lifted, the worker moves the fixing member 21 upward while climbing the utility pole. After reaching the top of the utility pole, the fixing member 21 is fixed at a certain height on the pole. Then, the rope retrieval assembly 22 is activated, causing the rope 23 to continuously wind up. At the same time, the container 10 is continuously lifted upward until it reaches the preset height. Then, the rope retrieval assembly 22 is controlled to stop winding up the rope 23, thus completing the lifting of the container 10. In this application, by fixing the fixing member 21 at a certain height and then operating the rope retrieval assembly 22 to wind up the rope 23 to lift the container 10 to the preset height, the physical exertion of the worker is avoided. It also avoids the possibility of the container 10 falling due to the worker not holding it firmly when manually lifting it, thereby reducing the safety hazards when lifting the container 10.

[0041] In one embodiment, the operation of the rope retrieval assembly 22 can be controlled by the operator who, after securing the fixing piece 21 at high altitude, directly starts the operation of the rope retrieval assembly 22 remotely through a remote control device or mobile communication device. Alternatively, it can be started by an assistant on the ground pressing the start switch on the rope retrieval assembly 22. This embodiment is not limited to these methods.

[0042] In one embodiment, the rope 23 is a steel wire. Of course, the rope 23 can also be made of other materials, as long as the rope 23 has sufficient hardness and flexibility.

[0043] In one embodiment, such as Figure 3 and Figure 4 As shown, the rope recovery assembly 22 includes a connecting assembly 221, a winding roller 222, and a drive motor 223. The connecting assembly 221 is connected to the top surface of the housing 10. The winding roller 222 is rotatably connected to the connecting assembly 221. The drive motor 223 is mounted on the connecting assembly 221 and is drivenly connected to one end of the winding roller 222. When the rope 23 needs to be recovered, the drive motor 223 is controlled to drive the winding roller 222 to rotate, so that the rope 23 is wound around the winding roller 222. When the rope recovery assembly 22 recovers the rope 23, the drive motor 223 can either drive the winding roller 222 to rotate clockwise to wind the rope 23 around the winding roller 222, or it can drive the winding roller 222 to rotate counterclockwise to wind the rope 23 around the winding roller 222. This embodiment does not limit this. It should be noted that in this embodiment, when the drive motor 223 is not started, the output shaft of the drive motor 223 can rotate freely, so that the winding roller 222 can also rotate freely, so that when the operator climbs the utility pole and drives the fixing part 21 to move upward, the rope 23 can be pulled out from the winding roller 222.

[0044] Optionally, the drive motor 223 can drive the winding roller 222 to rotate clockwise or counterclockwise. When the drive motor 223 drives the winding roller 222 to rotate clockwise, the rope 23 continuously winds around the winding roller 222; when the drive motor 223 drives the winding roller 222 to rotate counterclockwise, the rope 23 continuously pulls off the winding roller 222. Alternatively, when the drive motor 223 drives the winding roller 222 to rotate counterclockwise, the rope 23 continuously winds around the winding roller 222; when the drive motor 223 drives the winding roller 222 to rotate clockwise, the rope 23 continuously pulls off the winding roller 222. Thus, when it is necessary to raise the height of the box 10, the box 10 can be raised by driving the winding roller 222 to rotate clockwise or counterclockwise. When it is necessary to lower the box 10 from a height, the height of the box 10 can be lowered by driving the winding roller 222 to rotate in the opposite direction, thereby further facilitating the vertical movement of the box 10.

[0045] Optionally, the connecting assembly 221 includes two support blocks 2211, which are spaced apart. The two ends of the winding roller 222 are rotatably connected to the two support blocks 2211 respectively. A drive motor 223 is mounted on one of the support blocks 2211, and the drive motor 223 is located on the side of that support block 2211 facing away from the other support block 2211. Furthermore, the midpoint of the line connecting the two support blocks 2211 is located at the center of the top of the housing 10, to reduce the tilting of the housing 10 when it is lifted.

[0046] Furthermore, such as Figure 3 and Figure 4 As shown, the fixing member 21 is rod-shaped, and each support block 2211 has a receiving groove 2212 on the top of the side facing the other support block 2211. The shape of the receiving groove 2212 is adapted to the shape of the end of the fixing member 21. The receiving groove 2212 is used to place the end of the fixing member 21. That is, the fixing member 21 can be stored by placing both ends of the fixing member 21 into the corresponding receiving groove 2212, so as to prevent the fixing member 21 from rolling randomly when the box 10 does not need to be lifted, which would cause the rope 23 to be pulled out from the winding roller 222. It should be noted that when the fixing member 21 is placed in the receiving groove 2212, there is a sufficient gap between the fixing member 21 and the winding roller 222 to ensure that the rope 23 wound on the winding roller 222 will not interfere with the placement of the fixing member 21.

[0047] Optionally, such as Figure 4 As shown, a partition plate 2221 is provided on the winding roller 222, which divides the winding roller 222 into two sub-winding segments 2222 located on both sides of the partition plate 2221; two ropes 23 are connected to the fixing member 21, and the two ropes 23 are connected to the two sub-winding segments 2222 one by one; when the drive motor 223 drives the winding roller 222 to rotate to retract the ropes 23, the two ropes 23 will be wound around the corresponding sub-winding segments 2222 respectively, and the two ropes 23 will be retracted at the same time; in this way, the box 10 can be lifted by the two ropes 23, which can ensure the stability of the box 10 during the lifting process.

[0048] Furthermore, the two winding sections are of the same length, that is, the separator 2221 is located in the middle of the winding roller 222; in this way, the two ropes 23 have the same winding length on the winding roller 222, which can make full use of the winding roller 222 to recycle the ropes 23.

[0049] In one embodiment, such as Figure 1As shown, a handle 30 is also provided on the top of the box 10, which facilitates the manual lifting of the box 10 by the operator. Especially after the box 10 is raised to a predetermined height, the handle 30 makes it easier for the operator to retrieve the box 10. Preferably, there are two handles 30, spaced apart on both sides of the rope retrieval assembly 22, further improving the convenience for the operator to manually retrieve the box 10.

[0050] In one embodiment, such as Figure 2 As shown, the housing 10 includes a housing body 11 and a cover plate 12. The upper end of the housing body 11 is open, and the cover plate 12 is located at the opening of the housing body 11. The lifting mechanism 20 and the handle 30 are located on the upper surface of the cover plate 12. The cover plate 12 is detachably connected to the housing body 11 so as to install the positioning device body 300 in the housing 10 or remove the positioning device body 300 from the housing 10.

[0051] Optionally, such as Figure 2 As shown, a limiting member 13 is slidably connected to one side plate 111 of the box body 11. One end of the cover plate 12 is rotatably connected to the limiting member 13, and the other end of the cover plate 12 is engaged with the box body 11. When the end of the cover plate 12 away from the limiting member 13 is engaged with the box body 10, the cover plate 12 cannot rotate relative to the limiting member 13. At this time, the cover plate 12 will not detach from the opening of the box body 11. When the limiting member 13 slides relative to the box body 11 and slides until the cover plate 12 is no longer engaged with the box body 11, the cover plate 12 can rotate relative to the limiting member 13 to open the opening of the box body 11.

[0052] Specifically, the limiting member 13 has two inner side plates 136 on the side facing the cover plate 12. The two inner side plates 136 are arranged opposite each other and connected by a mounting shaft 137. The cover plate 12 has a protrusion 122 connected to the side facing the limiting member 13, and the protrusion 122 is rotatably connected to the mounting shaft 137. When the end of the cover plate 12 away from the limiting member 13 is engaged with the box body 11, the two inner side plates 136 are located inside the opening of the box body 11.

[0053] Furthermore, such as Figure 2As shown, an insert plate 121 is provided at the end of the cover plate 12 away from the limiting member 13, and a slot 113 adapted to the insert plate 121 is provided on the box body 11. The slot 113 is disposed opposite to the limiting member 13. The cover plate 12 is engaged with the box body 11 through the cooperation of the insert plate 121 and the slot 113. When the insert plate 121 is embedded in the slot 113, the cover plate 12 cannot rotate relative to the limiting member 13, and the cover plate 12 will not disengage from the opening of the box body 11. When the limiting member 13 slides relative to the box body 11 and slides until the insert plate 121 disengages from the slot 113, the cover plate 12 can rotate relative to the limiting member 13 to open the opening of the box body 11.

[0054] Optionally, such as Figure 5 As shown, both ends of the limiting member 13 are connected to connecting plates 131. When the limiting member 13 is located at the top of the side plate 111, the connecting plate 131 is located on one side of the box body 11. The connecting plate 131 is provided with threaded holes. The connecting plate 131 is provided with a fixing knob 132 corresponding to the threaded hole. The fixing knob 132 is threaded to the threaded hole, and the end of the fixing knob 132 facing the box body 11 is threaded to the box body 11. When the box body 10 is lifted by the lifting mechanism 20, in order to prevent the limiting member 13 from sliding and causing the insert plate 121 to disengage from the slot 113, both connecting plates 131 are connected to the box body 11 by fixing knobs 132 to fix the limiting member 13 to the box body 11. When it is necessary to open the cover plate 12, the two fixing knobs 132 must be unscrewed first, and then the cover plate 12 is slid to one side of the limiting member 13 so that the insert plate 121 disengages from the slot 113. Then the cover plate 12 can be rotated to open the opening of the box body 11.

[0055] Optionally, such as Figure 2 and Figure 6 As shown, a sliding groove 112 is provided on the side plate 111. The sliding groove 112 includes a vertical section 1122 and a horizontal section 1121. The end of the horizontal section 1121 away from the slot 113 is connected to the top of the vertical section 1122. The horizontal section 1121 is located on the top of the side plate 111 where the limiting member 13 is provided, and the vertical section 1122 is located on the outer wall of the side plate 111 where the limiting member 13 is provided. The limiting member 13 is provided with an installation notch 135 on the side facing the side plate 111. A slider 133 is hinged in the installation notch 135 through a connecting shaft. When the insert plate 121 is located in the slot, the slider is slidably connected in the horizontal section 1121. When the insert plate 121 is disengaged from the slot, the slider 133 is slidably connected in the vertical section 1122.

[0056] Furthermore, there are two slide grooves 112, which are spaced apart and parallel to each other on the side plate 111; correspondingly, there are also two sliders 133, which are connected to the two slide grooves 112 one by one. By setting two sliders 133 and two slide grooves 112, the sliding of the limiting member 13 on the housing body 11 is made more stable.

[0057] Furthermore, the sliding distance of the slider 133 in the horizontal section 1121 is greater than the width of the insert plate 121, so as to ensure that when the slider 133 slides to the top of the vertical section 1122, the insert plate 121 is completely disengaged from the slot 113, thereby allowing the top cover to be rotated.

[0058] Optionally, the slider 133 is T-shaped, and the shape of the groove 112 is adapted to the shape of the slider 133, with the wider end of the slider 133 embedded in the groove 112. Of course, the slider 133 and the groove 112 can also be other shapes, as long as it is ensured that the slider 133 can be stably slidably connected in the corresponding groove 112.

[0059] It is understandable that when it is necessary to remove the cover plate 12 from the top of the box body 11, first unscrew the fixing knob 132 from the connecting plate 131, then slide the cover plate 12 towards the limiting member 13. At the same time, the limiting member 13 also slides in the horizontal section 1121 through the slider 133 until the insert plate 121 is completely disengaged from the slot 113. At this time, the slider 133 is located at the top of the vertical section 1122. Then rotate the cover plate 12 upward and make the cover plate 12 vertical. Then rotate the limiting member 13 to make the slider 133 slide and connect with the vertical section 1122. Then move the cover plate 12 downward and move the limiting member 13 downward at the same time. In this way, the cover plate 12 can be placed on one side of the box body 10, which is convenient for operators to use the positioning instrument body 300 to locate faults.

[0060] Furthermore, a slider 133 is also provided on the side of the cover plate 12 facing the positioning instrument body 300, and the slider 133 is located on the cover plate 12 away from the limiting member 13; such as Figure 6 As shown, the top of the vertical section 1122 has an insertion port 1123; for example, there are two sliders 133, and the two sliders 133 correspond one-to-one with the two vertical sections 1122; when the cover plate 12 is rotated to the vertical position, and the cover plate 12 and the limiting member 13 move downward together, the slider 133 that is away from the limiting member 13 can be slid into the vertical section 1122 of the corresponding slide groove 112 through the insertion port 1123, so as to facilitate the placement of the cover plate 12 after it is opened.

[0061] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
