Description

Technical Field

[0001] The present invention relates to the field of power detection equipment, and in particular to a vehicle for a grounding grid detection device. Background Art

[0002] Currently, there are mainly three methods for detecting and evaluating grounding grids in China: one is to use a grounding impedance tester to measure the overall grounding impedance of the grounding grid; the second is to use a continuity tester to evaluate whether the grounding leads of each power equipment are well connected to the grounding grid; the third is to regularly select points for excavation to evaluate the corrosion degree of the grounding grid conductors. Since the detection equipment is relatively heavy, in order to facilitate the handling of the detection equipment at different measurement locations, a special vehicle is usually used to assist the operators in transporting the detection equipment or the cables required during the detection process.

[0003] The related technology can refer to the Chinese patent application with the publication number CN111391898B, which discloses a transport trolley and a substation grounding grid detection receiver system, belonging to the field of power measurement technology. It includes a vehicle body, and also includes wheels, sliding rods, fulcrum wheels and a positioning component. There are two wheels connected to the middle of the vehicle body. The sliding rod is located at one end of the vehicle body for pushing, and is slidably connected to the vehicle body in the vertical direction. The fulcrum wheel is arranged at the bottom end of the sliding rod. The positioning component is used to lock the sliding rod at a preset position with the vehicle body. When the sliding rod is at the preset position at the bottom end, the fulcrum wheel is used to abut against the ground. By driving the sliding of the fulcrum wheel through the sliding rod, the problems that a four-wheel transport trolley is inconvenient to continue pushing when encountering obstacles or gullies, and is quite laborious when climbing stairs are solved.

[0004] In view of the above related technology, during the actual measurement process, the health status of the grounding grid of old substations needs to be focused on. The drawings of the grounding grids of old substations are mainly paper materials. However, due to the long time, there are situations such as missing information and unupdated maps, and due to the changes in buildings, terrain and other reference objects on the ground, it is also very difficult to correspond the dimensions marked on the paper of the technical disclosure drawings to the actual position of the grounding grid in the site, resulting in the excavation operation being in a "blind excavation" state in most cases, making the measurement process relatively inconvenient. Summary of the Invention

[0005] In order to improve the convenience of grounding grid detection, the present application provides a vehicle for a grounding grid detection device.

[0006] The present application provides a vehicle for a grounding grid detection device, and adopts the following technical solutions: The vehicle includes a support bracket and moving wheels. There are two sets of moving wheels, both of which are located below the support bracket and are used to support the movement of the support bracket. It further includes: a positioning frame located on one side of the support bracket in the transverse direction. The positioning frame is provided with a disassembly and assembly member, and the support bracket is provided with a connection part one adapted to the disassembly and assembly member. The positioning frame is detachably connected to the connection part one through the disassembly and assembly member. A positioning module and a positioning antenna for receiving satellite signals are fixedly provided at the upper end of the positioning frame. The positioning antenna is electrically connected to the positioning module. A display screen wirelessly connected to the positioning module is fixedly provided at the upper end of the support bracket. The positioning module displays the grounding grid situation of the location where the vehicle is located on the display screen according to the satellite signal, and also displays the longitude and latitude information of the positioning location; a wire reel is located on the side of the positioning frame away from the support bracket. The wire reel is provided with the same disassembly and assembly member as the positioning frame. The support bracket is provided with a connection part two for connecting the disassembly and assembly member of the wire reel. A plurality of wire reels for storing cables are rotatably connected in the vertical direction at the upper end of the wire reel. The wire reel is provided with a rotating member for driving the wire reel to rotate.

[0007] By adopting the above technical solution, the support bracket is supported by the moving wheels to move. Under the connection action of the disassembly and assembly member, connection part one and connection part two, when the support bracket moves, it drives the positioning frame and the wire reel to move synchronously. When the positioning frame moves, it drives the positioning module and the positioning antenna to move synchronously. The positioning antenna synchronizes the position of the positioning module in real time according to the satellite signal, and feeds back the position information and the grounding grid situation of the current position to the display screen in real time, which is convenient for the operator to judge whether there is a grounding grid at the current position, thereby improving the positioning accuracy of the grounding grid and at the same time improving the work convenience of the operator. During the movement, the rotating member drives the wire reel to unwind, which is convenient for synchronously laying cables and is beneficial to further improving the work convenience of the operator.

[0008] Optionally, the disassembly and assembly member includes two sets of support legs, a multi-faceted rod and a plug board. Both sets of support legs are located at the lower end of the positioning frame and are between the two sets of moving wheels. The support legs are hinged to the positioning frame vertically, and the hinge axis of the support legs is perpendicular to the rotation axis of the moving wheels. One multi-faceted rod corresponds to one set of support legs. The multi-faceted rod is coaxial with the hinge axis of the corresponding support legs, and the multi-faceted rod passes through all the support legs of the same set along the axis direction and is slidably connected to the support legs. When the multi-faceted rod rotates, it drives the support legs to rotate. The plug board corresponds to the support legs one by one and is slidably connected to the positioning frame in the transverse direction. The connection part one includes a number of locking clamps one and a limiting block. The locking clamps one are fixedly provided at the lower end of the support bracket and are opposite to the corresponding plug boards. A moving member is provided between the support legs and the plug board. When the support legs rotate, the plug board is driven by the moving member to enter or disengage from the locking clamps one. The limiting block is fixedly connected to the support bracket and is located at one end of the corresponding multi-faceted rod, and the limiting block is provided with a multi-faceted hole adapted to the multi-faceted rod.

[0009] By adopting the above technical solution, in the initial state, the supporting legs are close to the positioning frame, and the multi-faceted rod is arranged in the multi-faceted hole. At this time, the bearing bracket restricts the rotation of the multi-faceted rod around its own axis through the limiting block, and then limits the supporting legs through the multi-faceted rod. Through the connection between the insertion plate and the locking buckle I, when the bearing bracket moves, it drives the positioning frame to move. When the positioning frame needs to be disassembled, move the multi-faceted rod along the axial direction. After the multi-faceted rod disengages from the multi-faceted hole, rotate the multi-faceted rod to drive all the supporting legs in the same group to rotate. The two groups of supporting legs cooperate to support the positioning frame. When the supporting legs rotate, the insertion plate is driven by the moving part to disengage from the locking buckle I, thereby releasing the connection between the positioning frame and the bearing bracket.

[0010] Optionally, the second connecting part includes a movable plate and a plurality of locking buckles II. The bearing bracket includes two side plates and a middle plate. The display screen is arranged above the middle plate. The two side plates are respectively vertically fixed at both ends of the middle plate. When the disassembly and assembly part is connected to the first connecting part, the positioning frame is located between the two side plates. The two groups of moving wheels correspond to the side plates respectively. The side plates are provided with connecting blocks for installing the moving wheels. The movable plate corresponds to the side plate one by one and is hinged to the side plate vertically. In one state of the movable plate, the side plate and the movable plate are in the same straight line. The locking buckles II are distributed along the length direction of the movable plate and are fixedly connected to the movable plate. When the side plate and the movable plate are in the same straight line, the locking buckles II are located at the lower end of the movable plate. The wire reel is located between the two movable plates and is locked with the locking buckles II through the insertion plates in the corresponding disassembly and assembly parts. At this time, the multi-faceted rods on the wire reel and the multi-faceted rods on the positioning frame are coaxial. A fixed disk is fixedly connected to one end of the multi-faceted rod far from the limiting block, and the fixed disk is provided with a limiting hole adapted to the multi-faceted rod.

[0011] By adopting the above technical solution, the middle plate limits the two side plates, and the two side plates cooperate with the middle plate to limit the positioning frame. In the initial state, the movable plate is located at the upper end of the side plate and is in a storage state. When the wire reel needs to be installed, rotate the movable plate to a state where it is in the same line as the side plate. At this time, move the wire reel between the two movable plates, and sequentially rotate the multi-faceted rods on the wire reel. While storing the supporting legs, connect the corresponding insertion plates to the locking buckles II. After the connection of the wire reel is completed, move the multi-faceted rods on the wire reel along the axial direction so that the multi-faceted rods are inserted into the limiting holes of the fixed disks on the positioning frame, thereby restricting the self-rotation of the multi-faceted rods on the wire reel, which is beneficial to improving the installation stability of the wire reel. Both the wire reel and the positioning frame are detachably connected to the bearing bracket, and the disassembly and assembly parts can be interchangeably arranged between the first connecting part and the second connecting part, which is beneficial to improving the working applicability.

[0012] Optionally, a first guide rail is fixedly provided along the length direction on the side of the side plate facing away from the middle connecting plate. The connecting block is slidably connected to the side plate along the first guide rail. The movable plate is fixedly connected with a second guide rail identical to the first guide rail. When the movable plate and the side plate are in the same straight line, the first guide rail and the second guide rail are in the same straight line and communicate with each other, enabling the connecting block to move between the first guide rail and the second guide rail. The connecting block is provided with a locking member for locking the movement of the moving block along the first guide rail.

[0013] By adopting the above technical solution, when the supporting bracket is only connected to the positioning bracket or the moving bracket singly, the moving wheel is only connected to the first guide rail through the moving block. When both the positioning bracket and the moving bracket are connected to the supporting bracket, the connecting block is moved between the first guide rail and the second guide rail. After the adjustment is completed, the moving block is locked by the locking member. While locking the relative rotation between the movable plate and the side plate through the connecting block, the supporting position of the moving wheel is adjusted, thereby adjusting the load-bearing center of the vehicle, making it more labor-saving for the operator to move the supporting bracket and being applicable to different installation situations.

[0014] Optionally, the supporting bracket further includes a handle. The handle is located at the upper end of the middle plate and is detachably connected to the middle plate by bolts. One end of the handle away from the middle plate is slidably connected with a mounting bracket along the length direction. The mounting bracket is provided with a fixing bolt for locking its own movement. The mounting bracket is further provided with a bracket that can be adjusted in angle vertically. The display screen is installed above the bracket.

[0015] By adopting the above technical solution, the handle is convenient for the operator to hold. When moving the supporting bracket, the operator pushes the supporting bracket through the handle. The handle fixes the mounting bracket through the fastening bolt, enabling the mounting bracket to hold up the bracket, and the bracket bears the display screen. The angle between the bracket and the mounting bracket can be adjusted. Therefore, it is convenient to adjust the angle of the display screen and is applicable to operators of different heights.

[0016] Optionally, the wire pay-off rack includes a support plate and a plurality of connecting shafts. The connecting shaft includes a rotating part and transmission parts fixedly provided at both ends of the rotating part. A support plate for supporting the rotation of the rotating part is fixedly provided at the upper end of the support plate. The transmission parts are coaxial with the rotating part, and the cross-section of the transmission part is polygonal. All the connecting shafts are coaxially arranged. A rotating member is used to drive any connecting shaft to rotate. The distance between adjacent connecting shafts is greater than the thickness of the winding disc along the axial direction. The winding disc is provided with a mounting member for detachably connecting with the connecting shaft. When the connecting shaft rotates, the winding disc is driven to rotate through the mounting member.

[0017] By adopting the above technical solution, the pallet supports the rotating part through the support plate, enabling the transmission part to rotate around its own axis under the support of the support plate. Under the connection action of the installation part, when the rotating part drives any connecting shaft to rotate, the connecting shaft drives the winding disc to rotate through the installation part, thereby realizing the winding or unwinding of the winding disc. The installation part facilitates the installation and replacement of the winding disc, which is beneficial to improving the applicability during the wire feeding process.

[0018] Optionally, the installation part includes two connecting pipes, two driving discs and connection keys. The winding disc is provided with a through hole along the axial direction. Both connecting pipes are located in the through hole and are slidably connected to the winding disc along the axial direction of the through hole. The connecting pipes are sleeved outside the transmission part and rotate synchronously with the transmission part. The distance between adjacent two connecting shafts is within the range of the maximum distance and the minimum distance between the mutually remote end faces of the two connecting pipes. The connection keys correspond to the connecting pipes one by one and are fixedly connected to one side of the two connecting pipes close to each other. The winding disc is provided with a limiting groove adapted to the connection key along the axial direction of the through hole. The connection key is located in the limiting groove and is slidably connected to the winding disc along the length direction of the limiting groove. The two driving discs are respectively located at both ends of the winding disc along the axial direction, and the driving discs rotate coaxially with the winding disc. The driving discs are provided with movable holes facilitating the passing of the connecting pipes. The outer circumference of the connecting pipe is provided with spiral guide grooves along the axial direction. The inner wall of the movable hole is fixedly connected with a guide block adapted to the spiral guide groove. The guide block is located in the spiral guide groove and is slidably connected to the connecting pipe along the spiral guide groove.

[0019] By adopting the above technical solution, the winding disc limits the connection key through the limiting groove, enabling the connecting pipe and the connection key to move along the axial direction of the through hole. In the initial state, the two connecting pipes are in a mutually remote position. At this time, the connecting pipes are sleeved outside the transmission part, and when the transmission part rotates, it drives the winding disc to rotate through the connecting pipes and the connection keys. The driving discs avoid the connecting pipes through the movable holes and limit the axial movement of the connecting pipes through the cooperation of the guide blocks and the spiral guide grooves. When the winding disc needs to be disassembled, rotate the driving disc so that the guide blocks cooperate with the spiral guide grooves to drive the connecting pipes to move along the axial direction. When the two connecting pipes approach each other, they are disengaged from the transmission part, thereby facilitating the removal of the winding disc from between the two transmission shafts.

[0020] Optionally, the winding disc includes an intermediate column and retaining rings fixed on both sides of the intermediate column. The outer surface of the intermediate column is provided with an installation groove along the axial direction. A clamping plate is arranged in the installation groove. The clamping plate is located on one side of the installation groove along the width direction. The clamping plate is arranged along the length direction of the installation groove, and the clamping plate is fixedly connected with a rotating rod parallel to the intermediate column. The end of the rotating rod is inserted into the retaining ring and is rotatably connected with the retaining ring. The retaining ring is threadedly connected with a butting rod along the diameter direction. The end of the clamping plate is fixedly connected with a pushing block facing the butting rod. When the butting rod contacts the pushing block, it drives the clamping plate to approach the axis of the intermediate column. An elastic member is arranged between the rotating rod and the retaining ring, and the elastic member drives the clamping plate to move away from the axis of the intermediate column in the natural state.

[0021] By adopting the above technical solution, a terminal is usually fixedly connected to the end of the cable. When the cable needs to be wound up, the terminal is placed into the installation groove, the abutting rod is rotated to make the abutting rod contact the pushing block, and the clamping plate is driven to move through the pushing block. Under the supporting action of the rotating rod, the clamping plate presses the terminal in the installation groove, thereby reducing the probability of the cable falling off the winding disc during the winding process. When unwinding, the abutting rod is rotated in the reverse direction to make the abutting rod away from the pushing block. At this time, the clamping plate moves away from the terminal under the action of the elastic member, thereby facilitating the terminal to fall off the installation groove along with the cable.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. The supporting bracket is moved by the moving wheels. Under the connection action of the disassembly and assembly member, the connecting portion I, and the connecting portion II, the supporting bracket drives the positioning frame and the wire unwinding frame to move synchronously when moving. When the positioning frame moves, it drives the positioning module and the positioning antenna to move synchronously. The positioning antenna synchronously locates the position of the positioning module according to the satellite model in real time, and feeds back the position information and the grounding grid situation at the current position to the display screen in real time, thereby facilitating the operator to judge whether there is a grounding grid at the current position, thereby improving the positioning accuracy of the grounding grid, and at the same time improving the work convenience of the operator. During the movement, the winding disc is driven to unwind by the rotating member, thereby facilitating the synchronous laying of the cable, which is beneficial to further improving the work convenience of the operator; 2. When the supporting bracket is only connected to the positioning frame or the moving frame singly, the moving wheels are only connected to the first guide rail through the moving blocks. When both the positioning frame and the moving frame are connected to the supporting bracket, the connecting block is moved between the first guide rail and the second guide rail. After the adjustment is completed, the moving block is locked by the locking member. While locking the relative rotation between the movable plate and the side plate by the connecting block, the supporting position of the moving wheels is adjusted, thereby adjusting the load-bearing center of the carrier, making it more labor-saving for the operator to move the supporting bracket, and being applicable to different installation situations.

[0029] The following further elaborates on the present application in conjunction with all the drawings.

[0030] The embodiment of the present application discloses a carrier for a grounding grid detection device.

[0031] Embodiment: Referring to Figure 1 and Figure 2 a carrier for a grounding grid detection device, the carrier includes a bracket 1 and two groups of movable wheels 11. The bracket 1 includes a middle plate 102 and two side plates 101. The two side plates 101 are parallel to each other. The middle plate 102 is fixedly connected between the two side plates 101. On one side of the two side plates 101 away from each other, a first guide rail 104 is fixedly provided along the length direction, and a connecting block 103 that slides along the first guide rail 104 is provided on the side plate 101. The movable wheel 11 is installed below the connecting block 103 and supports the side plate 101 through the connecting block 103. [[ID=??]]

[0032] Referring to Figure 1 and Figure 2 the connecting block 103 is provided with a locking member 105. The locking member 105 is a locking bolt. The locking bolt passes through the connecting block 103 and is threadedly connected to the connecting block 103. The side plate 101 is provided with a plurality of positioning holes along the length direction. When the locking bolt is inserted into any positioning hole, the connecting block 103 is positioned. By matching the locking bolt with positioning holes at different positions, the positions of the connecting block 103 and the movable wheel 11 can be adjusted conveniently.

[0033] Referring to Figure 1 and Figure 2 , a handle 15 is provided at the upper end of the middle plate 102. The handle 15 and the middle plate 102 are detachably connected by bolts. A mounting frame 151 is slidably connected to the upper end of the handle 15 along the length direction. The mounting frame 151 is threadedly connected with a fixing bolt 152. The handle 15 is provided with a plurality of fixing holes adapted to the fixing bolt 152 along the length direction. When the fixing bolt 152 is inserted into any fixing hole, the movement of the mounting frame 151 along the handle 15 is restricted. The mounting frame 151 is rotatably connected with a bracket 153 in the vertical direction, and a pressing rod is provided between the mounting frame 151 and the bracket 153. The pressing rod sequentially passes through the mounting frame 151 and the bracket 153 and is rotatably connected with both. The pressing rod is threadedly connected with a pressing nut, and by tightening the pressing nut, the mounting frame 151 is pushed to fit with the bracket 153.

[0034] Referring to Figure 1 and Figure 2 , the bracket 153 is fixedly connected with a plurality of first arc-shaped blocks with the pressing rod as the axis. The mounting frame 151 is fixedly connected with a plurality of second arc-shaped blocks corresponding to the first arc-shaped blocks. When the bracket 153 is close to the mounting frame 151, the first arc-shaped blocks and the second arc-shaped blocks are located in the same plane, and the first arc-shaped blocks and the second arc-shaped blocks are mutually staggered and abutted. The cooperation between the first arc-shaped blocks and the second arc-shaped blocks restricts the relative rotation between the mounting frame 151 and the bracket 153, which is beneficial to improving the fixing stability between the push plate and the mounting frame 151. A display screen 14 is installed at the upper end of the bracket 153. When an operator holds the handle 15, the display screen 14 faces the operator directly. The display screen 14 is used to display the map information of the location where the vehicle is located.

[0035] Referring to Figure 1 and Figure 2 , it further includes a positioning frame 2. The positioning frame 2 is provided with a disassembly and assembly member. The supporting bracket 1 is provided with a first connecting portion 12 detachably connected with the disassembly and assembly member. When the positioning frame 2 is connected with the supporting bracket 1, the positioning frame 2 is located between the two side plates 101. The disassembly and assembly member includes two groups of support legs 31, two multi-faceted rods 32 and an insertion plate 33. Both groups of support legs 31 are located at the lower end of the positioning frame 2 and are located between the two groups of moving wheels 11. One end of the support leg 31 in the length direction is vertically fixed with a cylindrical block. The support leg 31 is vertically hinged to the positioning frame 2 through the cylindrical block. The hinge axis of the support leg 31 is perpendicular to the rotation axis of the moving wheel 11. When the support leg 31 rotates to a state perpendicular to the positioning frame 2, its end far from the positioning frame 2 is flush with the lower end surface of the moving wheel 11.

[0036] Referring to Figure 1 and Figure 2, a multi-faceted rod 32 corresponds to a set of support legs 31, and the multi-faceted rod 32 is coaxial with the cylindrical block of the support leg 31. The multi-faceted rod 32 passes through the cylindrical blocks of the same set of support legs 31 along its own axis direction, and the multi-faceted rod 32 is slidably connected to the corresponding cylindrical block along the axis direction. When the multi-faceted rod 32 rotates around its own axis, it drives the support leg 31 to rotate through the cylindrical block. The insertion plate 33 corresponds to the support leg 31 one by one, and the insertion plate 33 is slidably connected to the positioning frame 2 along the axis direction of the moving wheel 11. A moving member 34 is provided between the insertion plate 33 and the support leg 31. The moving member 34 includes a plurality of tooth blocks 342 and a rack 341. The plurality of tooth blocks 342 are fixedly connected to the cylindrical block along the circumferential direction of the cylindrical block, and the rack 341 is fixedly connected to one end of the insertion plate 33, and the rack 341 meshes with the tooth blocks 342. When the cylindrical block rotates, it drives the rack 341 to move through the tooth blocks 342, and further drives the insertion plate 33 to approach or move away from the side plate 101. When the support leg 31 is in a position close to the positioning frame 2, the insertion plate 33 is located below the side plate 101. When the lower end of the support leg 31 moves away from the positioning frame 2, the insertion plate 33 gradually disengages from the side plate 101.

[0037] Refer to Figure 1 and Figure 2 , the connecting part one 12 includes a plurality of locking clasps one 121 and a plurality of limiting blocks 122. The locking clasps one 121 are fixedly connected to the lower end of the side plate 101 and correspond to the insertion plate 33 one by one. When the insertion plate 33 moves, it enters or disengages from the locking clasps one 121. When the insertion plate 33 enters the locking clasps one 121, it cooperates with the locking clasps one 121. Under the limiting action of all the insertion plates 33 and the locking clasps one 121, the positioning frame 2 is connected to the bearing bracket 1, and when the bearing bracket 1 moves, it drives the positioning frame 2 to move synchronously.

[0038] Refer to Figure 1 and Figure 2 , the limiting block 122 is located at one end of the multi-faceted rod 32 along the length direction, and a multi-faceted hole 123 adapted to the multi-faceted rod 32 is opened on the side of the limiting block 122 close to the multi-faceted rod 32. When the support leg 31 is in a position close to the positioning frame 2 or in a state perpendicular to the positioning frame 2, the operator moves the multi-faceted rod 32 along the axis direction to insert the multi-faceted rod 32 into the multi-faceted hole 123, thereby restricting the rotation of the multi-faceted rod 32 to improve the working stability of the support leg 31. A pushing spring is provided between any support leg 31 and the multi-faceted rod 32. The pushing spring is sleeved outside the multi-faceted rod 32, and a contact disk is fixedly connected to one end of the multi-faceted rod 32 close to the limiting block 122. One end of the pushing spring abuts against the contact disk, and the other end abuts against the support leg 31. When the pushing spring is in a natural state, it applies a thrust to the contact disk to make the multi-faceted plate stay in the multi-faceted hole 123.

[0039] Refer to Figure 1 and Figure 2, a positioning module 21 is installed at the upper end of the positioning frame 2, and a battery 23 for supplying power to the positioning module 21 is fixedly provided on the positioning frame 2. The positioning module 21 is connected with a positioning antenna 22 and a communication antenna 24. The positioning module 21 receives satellite signals through the positioning antenna 22 to locate the position of the vehicle, and the positioning module 21 is wirelessly connected with the display screen 14 through the communication antenna 24. The positioning module 21 displays the grounding grid condition of the location where the vehicle is located in real time through the display screen 14, thereby facilitating the operator to position the grounding grid and being beneficial to improving the work convenience of the operator.

[0040] Refer to Figure 2 and Figure 3 , it further includes a wire laying frame 4 for placing cables during measurement. The wire laying frame 4 includes a support plate 41 and a plurality of connecting shafts 42, and the same disassembly and assembly parts are provided below the support plate 41. The supporting frame 1 is further provided with a second connecting part 13 for connecting the wire laying frame 4. The second connecting part 13 includes a movable plate 131 and a plurality of locking clamps two 132. The movable plate 131 corresponds to the side plate 101 one by one, and the movable plate 131 is vertically hinged to the side plate 101 along the vertical direction.

[0041] Refer to Figure 2 and Figure 3 , in one state of the movable plate 131, the movable plate 131 is located above the side plate 101 and fits with the side plate 101. At this time, the movable plate 131 is in a storage state, and the wire laying frame 4 and the supporting frame 1 are not connected to each other. When the movable plate 131 is flipped to a state where it is in the same line as the side plate 101, one end of the movable plate 131 abuts against the side plate 101. At this time, the support plate 41 is located between the two movable plates 131. The structure of the locking clamp two 132 is the same as that of the locking clamp one 121 and is used to connect with the insertion plate 33 in the wire laying frame 4. The two movable plates 131 cooperate to realize the connection between the wire laying frame 4 and the supporting frame 1.

[0042] Refer to Figure 2 and Figure 3 , a second guide rail 133 is fixedly connected along the length direction of the side edge of the movable plate 131 away from the middle plate 102. When the movable plate 131 is in the same line state as the side plate 101, the first guide rail 104 and the second guide rail 133 are in the same axis and communicate with each other. At this time, the locking member 105 is loosened, and the connecting block 103 is moved between the first guide rail 104 and the second guide rail 133. After the locking member 105 is matched with the corresponding positioning hole, the relative movement between the movable plate 131 and the side plate 101 is restricted through the connecting block 103. At this time, the moving wheel 11 is located between the positioning frame 2 and the wire laying frame 4 and is thus directly below the overall center of gravity of the vehicle, facilitating the operator to move. The position of the moving wheel 11 can be adjusted according to the configuration of the vehicle, which is beneficial to improving the use convenience.

[0043] Refer to Figure 2 and Figure 3, for all the multi-faceted rods 32, a fixing plate is fixedly connected to one end away from the limit block 122, and a limit hole 322 adapted to the multi-faceted rod 32 is formed at one end of the fixing plate facing away from the corresponding multi-faceted rod 32. For the multi-faceted rod 32 in the wire pay-off frame 4, when it is necessary to limit the support leg 31 in the wire pay-off frame 4, the multi-faceted rod 32 in the wire pay-off frame 4 can be inserted into the limit hole 322 of the fixing plate in the positioning frame 2, which is beneficial to improving the working stability of the wire pay-off frame 4.

[0044] Refer to Figure 3 and Figure 4 , all the connecting shafts 42 are located above the support plate 41. A support plate 411 corresponding to each connecting shaft 42 is fixedly connected to the upper end of the support plate 41. The connecting shaft 42 includes a rotating part 421 and transmission parts 422 coaxially fixed at both ends of the rotating part 421. The cross-section of the rotating part 421 is circular, and the cross-section of the transmission part 422 is polygonal. The rotating part 421 passes through the support plate 411 and is rotatably connected to the support plate 411. Under the supporting action of the support plate 411, all the rotating parts 421 are coaxially arranged. A rotating member 6 is also installed at the upper end of the support plate 41. The rotating member 6 is a motor and is used to drive any one of the connecting shafts 42 to rotate.

[0045] Refer to Figure 4 and Figure 5 , a gap is left between adjacent connecting shafts 42. A winding disc 5 is arranged in the gap between two connecting shafts 42. The thickness of the winding disc 5 in the axial direction is less than the distance between two connecting shafts 42. The winding disc 5 includes an intermediate column 51 and two retaining rings 52. Both retaining rings 52 are sleeved and fixedly connected to the outside of the intermediate column 51, and the two retaining rings 52 are respectively located at both ends of the intermediate column 51 in the axial direction. An installation groove 513 is formed on the outer surface of the intermediate column 51 in the axial direction. A clamping plate 514 is arranged on one side in the width direction in the installation groove 513. A rotating rod 515 is fixedly connected to the side of the clamping plate 514 close to the axis of the intermediate column 51. The end of the rotating rod 515 in the length direction is inserted into the retaining ring 52 and is rotatably connected to the retaining ring 52 around its own axis. When the rotating rod 515 rotates, it drives the clamping plate 514 to rotate. An elastic member 522 is arranged between the rotating rod 515 and the retaining ring 52. The elastic member 522 is a torsion spring. One end of the torsion spring is fixedly connected to the retaining ring 52, and the other end is fixedly connected to the rotating rod 515. In the natural state of the elastic member 522, the clamping plate 514 is in contact with the inner wall of the installation groove 513 and is away from the axis of the intermediate column 51.

[0046] Refer to Figure 4 and Figure 5The retaining ring 52 is provided with an abutting rod 521 along the diameter direction. The abutting rod 521 is threadedly connected to the retaining ring 52. When the operator rotates the abutting rod 521, the abutting rod 521 moves closer to or away from the axis of the intermediate column 51. The clamping plate 514 is located at one end of the abutting rod 521 along the length direction, and a push block 516 is fixed to the end of the clamping plate 514 along the length direction, facing the abutting rod 521. The retaining ring 52 is provided with a movable groove for avoiding the push block 516. The push block 516 is located in the movable groove. When the abutting rod 521 is moved in the direction close to the axis of the intermediate column 51, the abutting rod 521 contacts the push block 516 and drives the push block 516 closer to the intermediate column 51. When the push block 516 moves, the clamping plate 514 rotates, and the elastic member 522 gradually deforms.

[0047] Reference Figure 4 and Figure 5 Both ends of the cable are connected to terminals, which consist of metal clips and a coating covering the outside of the metal clips. To reel the cable, place either terminal into the mounting slot 513 and rotate the abutment rod 521, causing it to push the clamping plate 514 to press the terminal into the mounting slot 513. At this point, rotate the intermediate column 51, causing it to reel the cable. This helps reduce the chance of the cable falling off the intermediate column 51 during reeling.

[0048] Reference Figure 4 and Figure 5 The reel 5 is provided with a mounting assembly for connecting to the connecting shaft 42. The mounting assembly includes two connecting tubes 71, two drive disks 72, and a plurality of connecting keys 73. The intermediate column 51 has a through hole 511 formed along its axis. Both connecting tubes 71 are located within the through hole 511 and are slidably connected to the intermediate column 51 along the length of the through hole 511. The drive disks 72 correspond one-to-one with the retaining rings 52 and are located on the side of the corresponding retaining ring 52 facing away from the intermediate column 51. The drive disks 72 are rotatably connected to the retaining rings 52 around the axis of the intermediate column 51. The drive disks 72 have a movable hole 721 formed along their axis, through which the connecting tubes 71 pass.

[0049] Reference Figure 4 and Figure 5 The multiple connecting keys 73 are divided into two groups, one corresponding to each connecting tube 71. The connecting keys 73 are located on the side of the two connecting tubes 71 that are adjacent to each other and are fixedly connected to the outer surface of the corresponding connecting tube 71. The intermediate column 51 has a retaining groove 512 along its axis that is compatible with the connecting keys 73. The connecting keys 73 are located within the retaining groove 512 and are slidably connected to the intermediate column 51 along the length of the retaining groove 512. The intermediate column 51 uses the connecting keys 73 to limit the connecting tubes 71, so that when the connecting tubes 71 rotate, the intermediate column 51 also rotates.

[0050] Reference Figure 4 andFigure 5 A spiral guide groove 711 is circumferentially formed on the outer circumference of the connecting pipe 71. A guide block 722 is fixedly connected to the inner wall of the movable hole 721 of the driving disk 72. The guide block 722 is located in the spiral guide groove 711 and is slidably connected to the connecting pipe 71 along the length direction of the spiral guide groove 711. Under the limiting action of the connecting key 73, when an operator rotates the driving disk 72, the driving disk 72 drives the connecting pipe 71 to move along the axial direction through the guide block 722. The two connecting pipes 71 have a disassembly state with the closest distance and a working state with the farthest distance. The driving disk 72 is threadedly connected with a positioning screw. The retaining ring 52 is provided with a plurality of locking holes corresponding to the positioning screws. When the connecting pipe 71 is in the disassembly state or the working state, the positioning screw passes through the driving disk 72 and is inserted into the corresponding positioning hole.

[0051] Refer to Figure 4 and Figure 5 Both end faces of the two connecting pipes 71 facing away from each other are provided with transmission holes adapted to the transmission parts 422. When the winding disk 5 is located between the two connecting shafts 42 and the two connecting pipes 71 are in the working state, the two connecting pipes 71 are respectively sleeved on two adjacent transmission parts 422 through the transmission holes. When the connecting shaft 42 rotates, the rotation of the connecting pipe 71 is driven through the cooperation of the transmission part 422 and the transmission hole, and the connecting pipe 71 drives the winding disk 5 to rotate, so as to realize the winding or unwinding of the cable. The adjacent two connecting shafts 42 are driven through the winding disk 5, so as to realize the synchronous rotation of all the connecting shafts 42 and the winding disk 5.

[0052] Refer to Figure 4 and Figure 5 When it is necessary to disassemble or replace the winding disk 5, the operator rotates the driving disk 72 to make the two connecting pipes 71 approach each other. When the two connecting pipes 71 are in the closest disassembly state, the distance between the end faces of the two connecting pipes 71 facing away from each other is less than the distance between the two connecting shafts 42. At this time, it is convenient for the operator to remove the winding disk 5 from between the two connecting shafts 42.

[0053] The working principle of the vehicle of the grounding grid detection device in the embodiment of the present application is as follows: The moving wheels 11 provide support for the carrier bracket 1. Under the action of the disassembly and assembly parts, the connecting part 12 and the connecting part 13, when the carrier bracket 1 moves, it drives the positioning frame 2 and the wire reel 4 to move synchronously. When the vehicle moves, the positioning antenna 22 updates the position of the positioning module 21 in real time according to the satellite signal, and feeds back the position information and the grounding grid situation at the current position to the display screen 14, thereby facilitating the operator to judge whether there is a grounding grid at the current position, which is beneficial to improving the positioning accuracy of the grounding grid and at the same time improving the work convenience of the operator. Moreover, by setting the wire reel 4 and the winding reel 5, the winding or unwinding of the cable can be realized during the movement of the vehicle, and both the wire reel 4 and the winding reel 5 can be disassembled and replaced, which can be applicable to a variety of different working environments and is beneficial to further improving the work convenience of the operator.

[0054] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
