Description

Technical Field

[0001] The utility model belongs to the field of automated robots, and particularly relates to an equipotential device and a coating robot. Background Art

[0002] In contemporary society, electricity plays a very important role. Therefore, live working is often chosen for the maintenance and repair operations of high-voltage cables. At the same time, the development of coating robot technology is gradually replacing the traditional manual live operation mode. However, when the above two are combined, a new problem arises: that is, when the coating robot touches the unpowered high-voltage bare conductor instantaneously, a discharge phenomenon will occur, which is extremely likely to cause damage to the electronic devices of the coating robot. Therefore, usually, the coating robot remains powered off before touching the high-voltage bare conductor, and at the same time, the operator uses an equipotential rod to make the equipotential treatment between the coating robot and the high-voltage bare conductor, and then turns on the robot power manually to ensure the normal operation of the coating robot. The consequence of this is that it is a waste of time and manpower. Summary of the Utility Model

[0003] The technical object of the utility model is to provide an equipotential device, aiming to liberate manual operation, so that the coating robot can adaptively maintain an equipotential state with the cable.

[0004] To solve the above technical problems, the utility model provides an equipotential device for being installed on the main body of a coating robot, including:

[0005] An equipotential rod, one end of which is a touch end and the other end is a connection end. The connection end is used for rotatably connecting with the main body, and the touch end is used for touching the cable;

[0006] A restoring member, which is fixedly connected with the main body and is drivingly connected with the connection end. The restoring member is used to provide the driving force for the equipotential rod to return to its original position after rotating relative to the main body.

[0007] In one embodiment, it further includes a first limiting plate and a second limiting plate. The first limiting plate and the second limiting plate are arranged at intervals, and the arrangement direction is perpendicular to the rotation plane of the equipotential rod;

[0008] The connection end of the equipotential rod is located between the first limiting plate and the second limiting plate and is rotatably connected with the two. The distance between the first limiting plate and the second limiting plate is equal to the length of the connection end in the arrangement direction;

[0009] Both the first limiting plate and the second limiting plate are used for being fixedly connected with the main body, and the arrangement direction is the walking direction of the coating robot on the cable.

[0010] In one embodiment, the restoring member is an elastic member. The fixed end of the elastic member is fixedly connected to the main body, and the free end of the elastic member is fixedly connected to the connecting end. When the equipotential bar rotates relative to the main body, the elastic member can deform to provide a driving force for driving the equipotential bar to rotate in the reverse direction.

[0011] In one embodiment, it further includes a fixing post for connecting to the main body. The equipotential bar is sleeved on the fixing post on one side close to the connecting end and can rotate relative to the fixing post. The side of the connecting end facing away from the fixing post is fixedly connected to the free end of the elastic member;

[0012] When the connecting end rotates, it will stretch the length of the elastic member to make the elastic member have an elastic force.

[0013] In one embodiment, the restoring member is a magnetic member. There are three magnetic members in total, and the three magnetic members have the same magnetism. One of the magnetic members is located on the connecting end and fixedly connected to the connecting end, and the other two magnetic members are located on both sides of the connecting end and fixedly connected to the main body;

[0014] The repulsive force between two adjacent magnetic members is configured to be less than the pressure of the external cable on the equipotential bar.

[0015] This application also provides a coating robot, including the coating robot provided in any of the above embodiments, and further including a main body. The equipotential device is connected to one side of the main body.

[0016] In one embodiment, there are two sets of equipotential devices. One set is connected to one side of the main body, and the other set is connected to the other side of the main body;

[0017] The two touch ends of the two equipotential bars in the two sets of equipotential devices are arranged in a crossed manner.

[0018] In one embodiment, the main body includes a housing. Electronic devices are wrapped inside the housing. The housing is made of a metal material and is electrically connected to the equipotential bar.

[0019] In one embodiment, the main body includes a traveling component and a loading box. The loading box is detachably connected to the base of the traveling component, and the equipotential device is detachably connected to the side of the loading box facing away from the base;

[0020] The traveling component is used to move on the cable, and the loading box is used to load the coating glue.

[0021] In one embodiment, there are multiple loading boxes, and the multiple loading boxes are detachably connected to each other.

[0022] Compared with the prior art, the beneficial effects of the coating robot of the present utility model are as follows: The equipotential rod benefits from the restoring force of the restoring member and is resilient. When the high-voltage cable on the coating robot is being coated, the cable contacts the touch end of the equipotential rod. As the coating robot approaches the cable, the cable will apply a rotational force to the equipotential rod, and the equipotential rod rotates around the main body of the coating robot. After the equipotential rod rotates to a position where the cable can pass through, the restoring member drives the equipotential rod to rebound back to its original position. When the high-voltage cable is being removed from the coating robot, the equipotential rod will cause the equipotential rod to rotate. When the cable has completely passed through, the equipotential rod is driven by the restoring member to return to its original position. The equipotential device provided in this application can make the coating robot and the high-voltage cable at the same potential, ensuring the safety of the coating robot. At the same time, the equipotential rod can reset itself, so no manual intervention is required, saving manpower and time. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Referring to Figure 1 , Figure 1 , a schematic structural diagram of the equipotential device 100 is shown. The present application provides an equipotential device 100, which is applied to a coating robot to ensure the safety of electronic devices in the coating robot. It mainly includes an equipotential bar 110 and a restoring member 120. One end of the equipotential bar 110 is a touch end 111, and the other end is a connection end 112. The connection end 112 is used for rotatably connecting with the main body 200 of the coating robot, and the touch end 111 is used for touching the cable 10. The restoring member 120 is fixedly connected to the main body 200 and is drivingly connected to the connection end 112. The restoring member 120 is used to provide a driving force for the equipotential bar 110 to return to its original position after rotating relative to the main body 200.

[0030] Compared with the prior art, the beneficial effects of the coating robot of the present utility model are as follows: The equipotential bar 110 benefits from the restoring force of the restoring member 120 and is resilient. When the high-voltage cable 10 is on the coating robot, the cable 10 contacts the touch end 111 of the equipotential bar 110. As the coating robot approaches the cable 10, the cable 10 will give the equipotential bar 110 a rotational force, and the equipotential bar 110 rotates around the main body 200 of the coating robot. After the equipotential bar 110 rotates to a position where the cable 10 can pass through, the restoring member 120 drives the equipotential bar 110 to rebound back to its original position. When the high-voltage cable 10 is under the coating robot, the equipotential bar 110 will cause the equipotential bar 110 to rotate. When the cable completely passes through, the equipotential bar 110 is driven by the restoring member 120 to return to its original position. The equipotential device 100 provided in this application can make the coating robot and the high-voltage cable 10 at the same potential, ensuring the safety of the coating robot. At the same time, the equipotential bar 110 can reset itself, so no manual intervention is required, saving manpower and time.

[0031] In other embodiments, the equipotential device 100 can be changed to a form of a spring wire / pull spring plus a screw. The screw fixes the spring wire / pull spring on the main body 200 of the coating robot, and one is fixed on each side of the main body 200, showing an outward V shape. By virtue of the high-elastic material property of the spring steel itself, when the cable 10 contacts the spring wire / pull spring, the spring wire / pull spring undergoes elastic deformation. When the cable no longer contacts the spring wire / pull spring, the spring wire / pull spring automatically bounces back to its original position.

[0032] Figure 2 The position diagram of the installation of the equipotential device 100 on the coating robot is shown. In one embodiment, the present application further provides a coating robot, including the coating robot provided in any of the above embodiments, and further including a main body 200. The equipotential device 100 is connected to one side of the main body 200. The side of the main body 200 of the coating robot connected to the equipotential device 100 is the side closest to the cable 10. Refer to Figure 2 , when the coating robot is grabbed by a drone to a position higher than the cable 10, it will be translated to directly above the cable 10, and then the coating robot will be slowly approached to the cable 10. The equipotential device 100 is located on the lowermost side of the main body 200 of the coating robot, so it will first contact the cable 10. After the cable 10 is electrically connected to the equipotential bar 110, the outer shell 210 of the main body 200 of the coating robot will be electrified, and the outer shell 210 forms a Faraday cage, thereby protecting the safety of the internal electronic devices.

[0033] Preferably, refer to Figure 2In one embodiment, two groups of equipotential devices 100 are provided, one group of which is connected to one side of the main body 200, and the other group of which is connected to the other side of the main body 200 in the horizontal direction. The two contact ends 111 of the two equipotential rods 110 in the two groups of equipotential devices 100 are arranged crosswise. Because if the position of the drone is improper, for example, the staff has a visual error, a single equipotential rod 110 may be offset from the cable 10, so that the cable 10 cannot touch the equipotential rod 110, and the distance between the cable 10 and the coating robot main body 200 is too close, resulting in discharge. The crossing of the two equipotential rods 110 can increase the lateral distance, ensuring that the cable 10 will definitely pass between the two equipotential rods 110.

[0034] See also Figure 1 In one embodiment, the equipotential device 100 further includes a first limiting plate 130 and a second limiting plate (not shown). In order to facilitate viewing of the structure between the first limiting plate 130 and the second limiting plate, the second limiting plate is not shown. Figure 1 As shown in FIG. 1 , the first limiting plate 130 and the second limiting plate are arranged at intervals, and the arrangement direction is perpendicular to the rotation plane of the equipotential rod 110, so it can be imagined that the second limiting plate is Figure 1 The connection end 112 of the equipotential rod 110 is located between the first limiting plate 130 and the second limiting plate and is rotatably connected to the two. The spacing distance between the first limiting plate 130 and the second limiting plate is equal to the length of the connection end 112 in the arrangement direction. The first limiting plate 130 and the second limiting plate are both used for fixed connection with the main body 200, and the arrangement direction is the walking direction of the coating robot on the cable 10.

[0035] In the above embodiment, the rotation plane of the equipotential rod 110 is perpendicular to the walking direction of the coating robot on the cable 10. Since the walking direction of the coating robot is the length direction of the cable 10, the rotation plane of the equipotential rod 110 is perpendicular to the cable 10. In this way, when the cable 10 contacts the equipotential rod 110, it is a vertical contact. Compared with sharp-angle contact, vertical contact prevents the equipotential rod 110 and the cable 10 from slipping during the contact process and the contact time is longer, which makes the coating robot safer.

[0036] There are many types of reply messages 120, see Figure 1 In one embodiment, the return member 120 is an elastic member, the fixed end of the elastic member is fixedly connected to the main body 200, the free end of the elastic member is fixedly connected to the connecting end 112, and the equipotential rod 110 rotates relative to the main body 200. The elastic member can deform to provide a driving force to drive the equipotential rod 110 to rotate away from the cable 10.

[0037] In the above embodiment, the elastic member may be a spring or a shrapnel, etc., and a spring is used in the present application. When the equipotential rod 110 is rotated by the driving force of the cable 10, the connecting end 112 at the end of the equipotential rod 110 will rotate, thereby extending the length of the elastic member. When the cable 10 passes through the equipotential rod 110, the elastic force generated by the deformation of the elastic member will drive the equipotential rod 110 to return to its original position.

[0038] In the above embodiment, the second limiting plate may be the main body 200 of the coating robot itself, that is, the first limiting plate 130 is fixed to the main body 200 by screws or the like and keeps a certain distance from the main body 200 to accommodate the elastic member and the equipotential rod 110 .

[0039] For details, see Figure 1 In one embodiment, a fixing column 140 is provided on the main body 200 of the coating robot, and the side of the equipotential rod 110 close to the connection end 112 is sleeved on the fixing column 140 and can rotate relative to the fixing column 140, and the side of the connection end 112 away from the fixing column 140 is fixedly connected to the free end of the elastic member. Therefore, with the fixing column 140 as the fulcrum, the equipotential rod 110 has actually become a lever structure, and when the contact end 111 of the equipotential rod 110 touches the cable 10 and rotates, the connection end 112 will rotate synchronously to stretch the length of the elastic member.

[0040] In the above embodiment, the fixing column 140 can be fixedly connected to the main body 200, and the equipotential rod 110 rotates relative to the fixing column 140, or the fixing column 140 can be rotatably connected to the main body 200, and the equipotential rod 110 is fixedly connected to the fixing column 140.

[0041] In other embodiments, the restoring member 120 may be a magnetic member, such as a magnet, and there are three magnetic members in total, the three magnetic members have the same magnetic properties, one of the magnetic members is located on the connecting end 112 and fixedly connected to the connecting end 112, and the other two magnetic members are located on both sides of the connecting end 112 and fixedly connected to the main body 200. The repulsive force between two adjacent magnetic members is smaller than the pressure of the external cable 10 on the equipotential rod 110.

[0042] In the above embodiment, the magnetic parts at both ends jointly repel the magnetic part in the middle, and the magnetic part in the middle is fixedly connected to the equipotential rod 110, so the equipotential rod 110 is kept stationary under balanced force. When the equipotential rod 110 contacts the cable 10, the cable 10 provides pressure to the equipotential rod 110. Since the repulsive force is less than the pressure, the equipotential rod 110 rotates, and the magnetic part in the middle will be biased towards the magnetic part on one of the two sides.

[0043] When the cable 10 leaves the equipotential rod 110, the pressure disappears, and the forces exerted by the magnetic components on both sides on the middle magnetic component are different in magnitude. Therefore, it will drive the equipotential rod 110 to rotate in the reverse direction until it returns to its original position and the force balance is re-established.

[0044] Refer to Figure 2 , in one embodiment, the main body 200 includes a traveling component 220 and a loading box 230. The loading box 230 is detachably connected to the base of the traveling component 220, and the equipotential device 100 is detachably connected to the side of the loading box 230 facing away from the base. The traveling component 220 is used to move on the cable 10, and the loading box 230 is used to load the coating glue 240. The traveling component 220 mainly includes traveling wheels, a motor, and a transmission component for driving the traveling wheels to travel on the cable 10. The motor drives the traveling wheels to rotate through the transmission component, thereby achieving the effect of moving on the cable 10. The coating glue 240 in the loading box 230 can be extruded onto the cable 10 to complete the coating effect on the cable 10.

[0045] Preferably, in one embodiment, there are multiple loading boxes 230, and the multiple loading boxes 230 are detachably connected to each other. Figure 2 A total of two loading boxes 230 are suspended, and being distributed on both sides of the traveling component can maintain the balance effect of the coating robot on the cable 10. More loading boxes 230 can be suspended as needed. Each loading box 230 can load two coating glues 240, which mainly depends on the volume of the coating glue 240 and the volume of the loading box 230. For a relatively thick cable 10, a relatively long distance can be coated at one time. When the coating robot is used for a relatively thin cable 10 or the cable 10 needs to be coated over a short distance, the redundant loading boxes 230 can be removed, and only two loading boxes 230 need to be loaded. Therefore, the coating robot provided in this application with detachably connected loading boxes 230 can be applied in various working conditions, enhancing the applicability and working efficiency.

[0046] The following effects can be achieved after installing two groups of equipotential devices 100 on the coating robot provided in this application:

[0047] 1. This kind of device makes the outer shell 210 of the main body 200 of the coating robot be equipotentially connected to the high-voltage cable 10 to form an equipotential field, preventing the high-voltage cable 10 from damaging the electronic devices of the coating robot.

[0048] 2. When the coating robot contacts the high-voltage cable 10, it first contacts the equipotential device 100, ensuring that the discharge position is at a certain place on the equipotential rod, avoiding high-voltage discharge on the lines and circuit boards of the main body 200 of the coating robot, and at the same time making the coating robot form an equipotential, ensuring the stable function of the machine.

[0049] 3. When the coating robot detaches from the high-voltage cable 10, the equipotential rod contacts the high-voltage cable 10 last, so that an equipotential is formed between the robot and the high-voltage cable 10 for a period of time after detachment, avoiding electric shock damage caused by the potential difference after the robot leaves the high-voltage cable 10.

[0050] 4. After the coating robot leaves the high-voltage cable 10, the position that first contacts the ground is the equipotential bar 110. The equipotential bar 110 discharges to the ground to form an equipotential with the ground, thereby ensuring that the main body 200 of the robot is not damaged by the discharge and improving the safety of personnel contacting the machine at the same time.

[0051] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
