Description

Technical Field

[0001] The invention relates to the technical field of power transmission line external damage prevention monitoring and alarm devices, and in particular to a safety distance monitoring device for preventing overhead lines from being damaged by operating vehicles. Background Art

[0002] Overhead power transmission line damage prevention management is an important measure to ensure the safe and stable operation of the power grid. Under the overhead lines of power transmission and distribution, there are often construction vehicles such as power engineering vehicles, aerial work vehicles, and cranes. Due to the negligence of operators, overhead lines are often accidentally damaged, which will not only cause power outages, but also may cause casualties.

[0003] The existing overhead line anti-breakage monitoring device can only be fixedly installed at a certain position of the construction vehicle. After the installation is completed, it is difficult to adjust it again. However, since the vehicle often changes its position during construction, it is impossible to confirm which part will cause potential damage risks to the overhead line. In particular, for cranes, after the boom is extended to a certain length, it will be out of the reach of the operator, and the position of the overhead line anti-breakage monitoring device cannot be adjusted in time according to the specific conditions of the construction, resulting in the overhead line anti-breakage monitoring device being unable to accurately monitor the safe construction distance relative to the overhead line. Summary of the invention

[0004] The purpose of the present invention is to provide a safety distance monitoring device for preventing overhead line operation vehicles from external damage. Based on the sliding connection between the inner slip ring and the outer fixed ring, an opening and closing effect can be formed. In conjunction with the bridging effect formed by the bridge plug-in, a path for convenient surrounding movement of the movable monitoring component can be formed, thereby achieving the purpose of dynamic surround monitoring of the construction environment. At the same time, in conjunction with the linkage rotation of the distance monitoring module itself, the accuracy of monitoring against external damage can be further improved.

[0005] The object of the present invention is achieved through such a technical solution, a safety distance monitoring device for preventing external damage of an overhead line working vehicle, comprising an opening and closing ring component, a displacement reference component and a movable monitoring component, the opening and closing ring component comprising an outer solid ring and an inner sliding ring, the displacement reference component comprising a bridge plug-in, a bridge clamping column, a buffer connection block and a guide side groove, and the movable monitoring component comprising an outer solid shell and a distance monitoring module; One end of the inner slip ring is slidably connected with the inner part of the outer fixed ring, both ends of the outer arc surface of the inner slip ring are provided with slip ring teeth, both ends of the outer arc surface of the outer fixed ring are provided with fixed ring teeth, and the openings at both ends of the outer fixed ring are closed structures. The bridge plug-in is respectively screwed on the openings at both ends of the outer fixed ring, and both ends of the outer arc surface of the bridge plug-in are provided with bridge teeth. Slip ring side grooves are provided in both side end surfaces of the inner slip ring, and fixed ring side grooves are provided in both side end surfaces of the outer fixed ring, and the path of the starting end of the fixed ring side groove changes with the closing structure of the outer fixed ring. Both end faces are provided with bridge side grooves, the buffer connection block is fixed at the openings at both ends of the outer fixed ring, the guide side grooves are respectively provided at the two end faces of the buffer connection block, and one end of the inner side surface of each group of bridge plugs is fixed with a bridge clamp seat, the bridge clamp column is fixed on the inner arc surface of the inner slip ring, and after the inner slip ring slides relative to the outer fixed ring and is unfolded into place, the bridge plug can form a bridge, the slip ring tooth body, the bridge tooth body and the fixed ring tooth body on the same side form a closed loop path, and the slip ring side groove, the bridge side groove, the guide side groove and the fixed ring side groove on the same side form a closed loop path; The inner end of the outer solid shell is rotatably connected with displacement gears that can rotate automatically in pairs, and the displacement gears can mesh with the teeth of the closed-loop path formed by the slip ring teeth, the bridge teeth and the solid ring teeth. The inner ends of the outer solid shell are symmetrically slidably connected with inner sliding columns that bounce inward on both sides, and the inner sliding columns can slide in the grooves of the closed-loop path formed by the slip ring side grooves, the bridge side grooves, the guide side grooves and the solid ring side grooves. The distance monitoring module is installed on the outer end surface of the outer solid shell, and a side solid column is fixed to the outside of one side of the outer solid shell. When the outer solid shell moves to the set position, the bridge plug-in is flipped up, and the bridge clamp can be inserted into the outside of the side solid column. The inner arc surfaces of the outer fixed ring and the inner sliding ring are both equipped with components connected to the boom support of a crane or other working vehicle. When the inner sliding ring forms a sliding retracted state relative to the outer fixed ring, it can be inserted into the outside of the front boom and connected to the outside of the boom. After the connection is completed, the outer fixed ring and the inner sliding ring form a full circular path around the boom.

[0006] The use process of the technical solution provided by the present invention is as follows: The movable monitoring component is a functional body used to realize the external damage prevention of the working vehicle. It can be fixedly installed in a certain position, or it can be installed at the front end of the crane boom based on the openable and closable circular ring structure composed of an outer fixed ring and an inner sliding ring, so that the movable monitoring component can not only extend with the boom, but also perform surround monitoring of the external environment of the front end of the boom based on the full circle path composed of the outer fixed ring and the inner sliding ring; After the inner sliding ring is slid in relative to the outer fixed ring, it can be inserted into the front end of the boom through the opening formed by the inner sliding ring and the outer fixed ring, and then slid and unfolded again to form a full circle path, and the components connected to the boom support installed by the inner arc surface of the outer fixed ring and the inner sliding ring can be fixed on the outside of the front end of the boom by the full circle formed by the inner sliding ring and the outer fixed ring; The purpose of setting the bridge plug-in is that the radius of the outer arc surface of the inner slip ring is smaller than the radius of the outer arc surface of the outer solid ring, which will make the slip ring tooth body opened on the outer arc surface of the inner slip ring and the solid ring tooth body opened on the outer arc surface of the outer solid ring unable to dock with each other. After the inner slip ring slides relative to the outer solid ring to form a full circle, the bridge plug-in is flipped into place, that is, after the bridge clamp seat is clamped on the outside of the bridge clamp column, the slip ring tooth body can form a closed loop path with the solid ring tooth body through the bridge tooth body, and similarly, the slip ring side groove can form a closed loop path with the bridge side groove, the guide side groove and the solid ring side groove; The purpose of setting the buffer connection block and the guide side groove is that the distance between the sliding ring side grooves opened on the two end surfaces of the inner sliding ring is smaller than the distance between the solid ring side grooves opened on the two end surfaces of the outer solid ring. In conjunction with the closing structure formed at both ends of the outer solid ring, the buffer connection block can form a transition between the closing structure at both ends of the bridge plug-in and the outer solid ring, that is, the guide side groove itself has a certain outward inclination, and the buffer connection block is a structure with a certain elasticity, which can make the inner end of the inner sliding column slide smoothly into the starting end of the solid ring side groove through the guide side groove; Through the coordinated transmission formed by the automatically rotating displacement gear and the slip ring gear body, the bridge gear body and the fixed ring gear body, and the coordinated transmission formed by the inner sliding column that always bounces inward and the slip ring side groove, the bridge side groove, the guide side groove and the fixed ring side groove, the movable monitoring component as a whole can form a dynamic surrounding movement around the front end of the boom.

[0007] By adopting the above technical solution, the present invention can achieve the following beneficial effects: (1) The present invention is based on the inner sliding ring and the outer solid ring which are slidably connected. By arranging a bridge plug-in at the end position of the sliding connection between the inner sliding ring and the outer solid ring, and setting the bridge plug-in to a rotatable state, the inner sliding ring can not only meet the requirement of sliding the inner sliding ring relative to the outer solid ring, but also play a bridging role between the inner sliding ring and the outer solid ring, so that the sliding ring tooth body forms a closed loop path with the solid ring tooth body through the bridge side groove, and the sliding ring side groove forms a closed loop path with the solid ring side groove through the cooperation of the bridge side groove and the guide side groove, so that the movable monitoring component can be moved to the position where the displacement gear cooperates with the sliding ring tooth body and the inner sliding column cooperates with the sliding ring side groove through the bridge tooth body on the outer arc surface of the bridge plug-in and the bridge side grooves opened on both end surfaces of the bridge plug-in to form a bridge effect, and smoothly transition to the position where the displacement gear cooperates with the solid ring tooth body and the inner sliding column cooperates with the solid ring side groove, so as to form a surrounding dynamic monitoring operation of the movable monitoring component; (2) The bridge holder fixed on the inner side of the bridge plug-in of the present invention is not only used to form a snap fit with the outer side of the bridge holder column to facilitate the bridge fixation of the bridge plug-in, but also used to, when the movable monitoring component stays in the position to cooperate with the inner slip ring, as the bridge plug-in is flipped up, the bridge holder can be snapped onto the outside of the side solid column on the outer side of the outer solid shell, thereby forming a mechanical lock of the position of the movable monitoring component when it is not in use, thereby preventing the movable monitoring component from moving freely when it is not in use.

[0013] Please refer to the attached Figure 1-16 An example of a safety distance monitoring device for preventing an overhead line from being damaged by an operating vehicle provided by the present invention is described; one end of an inner slip ring 102 in an opening and closing ring component 1 is slidably connected to the inside of an outer fixed ring 101, and the inner slip ring 102 can be slid relative to the outer fixed ring 101 to form a full circle path, and can also be slid into a position overlapping with the inner arc surface of the outer fixed ring 101 to form an opening, and both ends of the outer arc surface of the inner slip ring 102 are provided with slip ring teeth 201, and the outer arc surface of the outer fixed ring 101 The two ends of the outer ring 101 are provided with a fixed ring tooth body 202, and the setting distance of the two sets of slip ring tooth bodies 201 is equal to the setting distance of the two sets of fixed ring tooth bodies 202. The openings at both ends of the outer fixed ring 101 are closed structures. The bridge plug 207 is respectively screwed on the openings at both ends of the outer fixed ring 101. The two ends of the outer arc surface of the bridge plug 207 are provided with a bridge tooth body 208. The two side end faces of the inner slip ring 102 are provided with a slip ring side groove 203, and the two side end faces of the outer fixed ring 101 are provided with There is a fixed ring side groove 204, and the path of the starting end of the fixed ring side groove 204 changes with the closing structure of the outer fixed ring 101. The two end faces of the bridge plug 207 are provided with a bridge side groove 209. The buffer connection block 213 is fixed at the two end openings of the outer fixed ring 101 and will not interfere with the rotation of the bridge plug 207. The guide side grooves 214 are respectively provided at the two end faces of the buffer connection block 213. One end of the inner side of each group of bridge plugs 207 is fixed with a bridge clamp 210 , the bridge clamping column 212 is fixed on the inner arc surface of the inner slip ring 102, and after the inner slip ring 102 slides and unfolds to the position relative to the outer fixed ring 101, the bridge clamping seat 210 is just inserted into the outside of the bridge clamping column 212, and the bridge plug-in 207 can form a bridge, and the slip ring tooth body 201, the bridge tooth body 208 and the fixed ring tooth body 202 on the same side form a closed loop path, and the slip ring side groove 203, the bridge side groove 209, the guide side groove 214 and the fixed ring side groove 204 on the same side form a closed loop path; The inner end of the outer solid shell 601 is screwed in pairs with automatically rotatable displacement gears 604, and the displacement gears 604 can mesh with the teeth of the closed-loop path formed by the slip ring teeth 201, the bridge teeth 208 and the solid ring teeth 202. The inner ends of the outer solid shell 601 are also symmetrically slidably connected with inner sliding columns 613 that bounce inward, and the inner sliding columns 613 can slide in the grooves of the closed-loop path formed by the slip ring side grooves 203, the bridge side grooves 209, the guide side grooves 214 and the solid ring side grooves 204. The distance monitoring module 610 is rotatably mounted on the outer end surface of the outer solid shell 601, and a side solid column 616 is fixed to the outside of one side of the outer solid shell 601. When the outer solid shell 601 moves to the set position, the bridge plug-in 207 is flipped up, and the bridge holder 210 can be inserted into the outside of the side solid column 616, forming a state in which the movable monitoring component 6 is stably stationary as a whole; A co-driven bevel gear 617 is also transmission-connected above the displacement gear 604, a gain shaft seat 619 is fixedly installed in the main body of the outer solid shell 601, and the gain shaft 620 is rotationally connected in the gain shaft seat 619. The distance monitoring module 610 is fixedly installed on the top of the gain shaft 620, and the gain rotating bevel gear 618 is fixedly connected to the bottom end of the gain shaft 620 and meshes with the co-driven bevel gear 617, so that when the displacement gear 604 is transmitted, the transmission connection formed with the co-driven bevel gear 617 and the gain rotating bevel gear 618 can drive the distance monitoring module 610 to rotate synchronously; The inner arc surfaces of the outer fixed ring 101 and the inner slip ring 102 are both equipped with components connected to the boom support of a crane or other working vehicle. When the inner slip ring 102 forms a sliding retracted state relative to the outer fixed ring 101, it can be inserted into the outside of the front boom and connected to the outside of the boom. After the connection is completed, the outer fixed ring 101 and the inner slip ring 102 form a full circular path surrounding the boom.

[0014] Here’s how it works: The movable monitoring component 6 is a functional main body for realizing the external damage prevention of the working vehicle. It can be fixedly installed at a certain position, and can also be installed at the front end of the crane boom based on the openable and closable circular ring structure composed of the outer fixed ring 101 and the inner sliding ring 102, so that the movable monitoring component 6 can not only extend with the boom, but also can perform surrounding monitoring of the external environment of the front end of the boom based on the full circle path composed of the outer fixed ring 101 and the inner sliding ring 102; Since the inner sliding ring 102 can slide relative to the outer fixed ring 101, after the inner sliding ring 102 slides relative to the outer fixed ring 101, the inner sliding ring 102 and the outer fixed ring 101 form an opening, which can be inserted into the front end of the boom and then slid and unfolded again to form a full circle path. The components connected to the boom support installed by the inner arc surface of the outer fixed ring 101 and the inner sliding ring 102 can be fixed on the outside of the front end of the boom by the full circle formed by the inner sliding ring 102 and the outer fixed ring 101. The purpose of arranging the bridge plug-in 207 at the openings at both ends of the outer solid ring 101 is that, since the outer arc radius of the inner slip ring 102 is smaller than the outer arc radius of the outer solid ring 101, the slip ring tooth body 201 opened on the outer arc surface of the inner slip ring 102 and the solid ring tooth body 202 opened on the outer arc surface of the outer solid ring 101 will never be able to dock. After the inner slip ring 102 slides and expands relative to the outer solid ring 101 to form a full circle, the bridge plug-in 207 is flipped into place, that is, after the bridge clamping seat 210 is clamped on the outside of the bridge clamping column 212, the slip ring tooth body 201 can form a closed loop path with the solid ring tooth body 202 through the bridge tooth body 208; Similarly, the slip ring side groove 203 can form a closed loop path with the guide side groove 214 and the fixed ring side groove 204 through the bridge side groove 209; The purpose of setting the buffer connection block 213 and the guide side groove 214 is that the distance between the slip ring side grooves 203 opened on the two end surfaces of the inner slip ring 102 is smaller than the distance between the solid ring side grooves 204 opened on the two end surfaces of the outer solid ring 101. In conjunction with the closing structure formed at both ends of the outer solid ring 101, the buffer connection block 213 can form a transition between the closing structure at both ends of the bridge plug-in 207 and the outer solid ring 101, that is, the guide side groove 214 itself has a certain outward inclination, and the buffer connection block 213 is a structure with a certain elasticity, which can make the inner end of the inner sliding column 613 slide smoothly into the starting end of the solid ring side groove 204 through the guide side groove 214; Through the coordinated transmission formed by the automatically rotatable displacement gear 604 and the slip ring tooth body 201, the bridge tooth body 208 and the fixed ring tooth body 202, and the coordinated transmission formed by the inner sliding column 613 that always bounces inward and the slip ring side groove 203, the bridge side groove 209, the guide side groove 214 and the fixed ring side groove 204, the movable monitoring component 6 can be made to form a dynamic surrounding movement around the front end of the boom as a whole, so as to form a surrounding monitoring of the environment near the front end of the boom without blind spots, and can monitor the position of the overhead line near the front end of the boom in all directions, so as to more accurately form a monitoring operation of the anti-external damage safety distance of the overhead line; When the displacement gear 604 rotates, the gain shaft 620 can be driven to rotate through the transmission formed by the co-driving bevel gear 617 and the gain rotating bevel gear 618, so that the distance monitoring module 610 can rotate with the outer solid shell 601 as the reference, thereby cooperating with the surrounding movement formed by the movable monitoring component 6 as a whole, and improving the monitoring precision and accuracy of the environment; Furthermore, when the movable monitoring component 6 is installed alone at a certain location for use, the distance monitoring module 610 can also rotate with the outer solid shell 601 as a reference, thereby improving the monitoring accuracy.

[0015] The specific structures of the opening and closing ring component 1 and the displacement reference component 2 are as follows: Figure 4 , Figure 5 , Figure 6 , Figure 7and Figure 8 As shown, the slide groove 103 is provided in the middle of the main body of the outer fixed ring 101, and the slider 104 is fixed to one end of the outer arc surface of the inner sliding ring 102. The slider 104 is slidably connected in the slide groove 103 and will not be separated from the slide groove 103 at will; A closed-loop clamping groove 106 is symmetrically formed at the other end of the inner sliding ring 102, and a closed-loop clamping column 105 is symmetrically fixed to one end of the inner arc surface of the sliding groove 103; After the inner sliding ring 102 slides and unfolds into place relative to the outer fixed ring 101 to form a full circle, the closed-loop clamping column 105 on the same side can be just inserted into the closed-loop clamping groove 106, so that the inner sliding ring 102 can slide and unfold into place relative to the outer fixed ring 101 safely; The inner sliding ring 102 has chamfers on both sides of one end of the closed-loop clamping groove 106, so as to facilitate the clamping cooperation with the closed-loop clamping column 105; The bridge rotation groove 205 is provided at the openings at both ends of the outer fixed ring 101 to provide space for the rotation of the bridge plug 207. A side rotation shaft 217 is coaxially fixed on one side of the two end surfaces of the bridge plug 207. Side rotation holes 216 are provided in the main bodies on both sides of the bridge rotation groove 205. The side rotation shaft 217 on the same side is rotatably connected in the side rotation hole 216. A clearance slot 215 is also provided on one side of both end surfaces of the bridge plug-in 207 to eliminate interference with the buffer connection block 213 during the rotation of the bridge plug-in 207; Both ends of the outer arc surface of the inner slip ring 102 are also provided with abutment grooves 206. After the bridge plug-in 207 is bridged into place, one end of the inner side surface of the bridge plug-in 207 can just fit in the abutment groove 206, and the bridge clamp seat 210 can just be inserted into the outside of the bridge clamp column 212, which can easily form a stable and accurate bridging action of the bridge plug-in 207.

[0016] The specific structure of the movable monitoring component 6 is as follows: Fig.14 and Fig.15 As shown, displacement shaft seats 602 are coaxially fixedly installed on both sides of the inner end of the outer solid shell 601, and both ends of the displacement shaft 603 are rotatably connected in the displacement shaft seats 602, and the displacement gear 604 and the rotating gear 605 are both plugged and fixed on the outside of the displacement shaft 603; A displacement motor 606 is fixedly mounted on the top surface of the inner cavity of the outer solid shell 601. The driving gear 607 and the co-driving bevel gear 617 are both plugged and fixed in the rotating shaft of the displacement motor 606, and the driving gear 607 is meshed with the rotating gear 605. After the displacement motor 606 is started, the driving gear 607 and the rotating gear 605 form a matching transmission, which drives the displacement gear 604 to form a matching transmission with the slip ring gear body 201, the bridge gear body 208 and the solid ring gear body 202; A monitoring control mainboard 608 and a lithium battery 609 are also installed on the inner cavity top surface of the outer solid shell 601, and the distance monitoring module 610 and the lithium battery 609 are both connected to the monitoring control mainboard 608; Lower connecting ear seats 611 are fixed on both sides of the inner end of the outer solid shell 601, and a slide 612 is symmetrically fixedly installed in each group of lower connecting ear seats 611. The inner slide column 613 is slidably connected to the slide cylinder 612. The outer end opening of each group of slide cylinders 612 is also covered with an outer fixed seat 614. One end of the compression spring 615 is clamped with the end of the inner slide column 613, and the other end is clamped with the outer fixed seat 614, so that the inner slide column 613 can form an inward elastic force, and the inner slide column 613 can never get out of the slide cylinder 612; Since there is a fitting clearance between the displacement gear 604 and the slip ring tooth body 201, the bridge tooth body 208 and the fixed ring tooth body 202, the elastic inward inner sliding column 613 can form a smooth fitting transmission between the slip ring side groove 203, the bridge side groove 209, the guide side groove 214 and the fixed ring side groove 204 without jamming.

[0017] The receiving alarm unit 7 is installed in the working vehicle cab near the driver, which can be used to remind the driver. The receiving alarm unit 7 includes a signal receiving module 701 and an audible and visual alarm 702. The signal receiving module 701 and the audible and visual alarm 702 are both connected to the central processor 8. The monitoring control mainboard 608 is connected to the communication central processor 8. A communication channel can be established between the monitoring and control mainboard 608 and the central processing unit 8, and the monitoring information of the distance monitoring module 610 collected by the monitoring and control mainboard 608 can be fed back to the central processing unit 8.

The fixed ring inner rotating seat 401 is symmetrically fixed on the inner arc surface of the outer fixed ring 101, and will not interfere with the sliding fit between the inner slip ring 102 and the outer fixed ring 101. Each set of fixed ring inner rotating seats 401 is rotatably connected with a fixed ring outer rotating rod 402, and a fixed ring inner slot 404 is opened in the middle of the main body of each set of fixed ring outer rotating rods 402.

When the slip ring angle clamping seat 307 is clamped to the outside of the slip ring clamping column 308, and the fixed ring angle clamping seat 407 is clamped to the outside of the fixed ring clamping column 408, that is, when the slip ring inner support assembly 3 and the fixed ring inner support assembly 4 are both in the storage state, it will not affect the sliding and receiving action of the inner slip ring 102 relative to the outer fixed ring 101. This is because the fixed ring inner rotating seat 401 and the fixed ring clamping column 408 are both provided with sufficient inner space, which is enough to make the inner slip ring 102 slide to the set receiving position relative to the outer fixed ring 101; The slip ring inner support assembly 3 and the fixed ring inner support assembly 4 are also equipped with double locking components 5, which can lock the sliding position of the slip ring inner seat 303 relative to the slip ring outer rotating rod 302 and the sliding position of the fixed ring inner seat 403 relative to the fixed ring outer rotating rod 402.

The top of each set of side lock gear bodies 503 is fixed with an inter-shifting rack 507, and the gear bodies of the two sets of inter-shifting racks 507 are arranged opposite to each other. The inter-shifting rack slots 506 are respectively provided at both ends of the main body of the slip ring external rotation rod 302 and the fixed ring external rotation rod 402, and the inter-shifting rack slots 506 on the same side are connected to the side lock slots 502, and the inter-shifting racks 507 are slidably connected in the inter-shifting rack slots 506; A central rotating hole 508 is provided in the middle of the main body of the slip ring external rotating rod 302 and the fixed ring external rotating rod 402. A central fixed seat 509 is fixedly connected to the outer end of the central rotating hole 508. An operating rotating shaft 510 is rotatably connected to the central fixed seat 509. A central gear 511 is plugged and fixed to the inner end of the operating rotating shaft 510 and meshes with the mutually shifting racks 507 on both sides. By rotating the central gear 511, the two sets of mutually shifting racks 507 can be driven to move toward each other. The outer cover of the cavity formed by the side lock slide groove 502 and the intermovable rack slide groove 506 is connected to the outer cover 504. One end of the top spring 505 is clamped with the end of the side lock tooth body 503, and the other end is clamped with the inner side of the outer cover 504. Under the action of the inward supporting elastic force of the opposite side lock tooth body 503 formed by the top spring 505, the side lock tooth body 503 can be in a position to lock the rod tooth body 501 when there is no external force operation; By inserting a standard tool into the groove formed at the outer end of the operating shaft 510, the central gear 511 can be rotated to make the two sets of intershifted racks 507 move toward each other, thereby driving the side lock gear body 503 to disengage the locking cooperation with the inserted rod gear body 501, which facilitates the adjustment of the sliding position of the slip ring inner seat 303 relative to the slip ring outer rotating rod 302 and the sliding position of the fixed ring inner seat 403 relative to the fixed ring outer rotating rod 402, and can also safely and quickly lock the slip ring inner seat 303 and the fixed ring inner seat 403 in the adjusted position, so that the whole circle formed by the outer fixed ring 101 and the inner slip ring 102 can form a stable support connection with the front end outside of the boom through the slip ring inner support assembly 3 and the fixed ring inner support assembly 4.
