Description

Technical Field

[0001] The utility model belongs to the field of automated robots, and in particular relates to a coating robot. Background Art

[0002] Power grid transmission inevitably relies heavily on overhead conductors. As of now, the total length of bare overhead conductors nationwide exceeds 2 million kilometers. Overhead conductors require protection against electric shock, bird damage, and icing in various operating conditions. Currently, the most commonly used method is coating, where specialized materials are applied directly onto the conductors to create a protective coating. This method offers low cost, high durability, reliability, and efficiency, and eliminates the need for power outages.

[0003] Common coating robots typically feature one or two large barrels, using a push rod or gear-and-rack mechanism to squeeze the coating material from the barrels into the coating unit for coating. Because the number and volume of barrels are fixed, typical coating robots can only handle coating a certain range of wire diameters. Thinner wires or porcelain bottles struggle with the heavy weight of large barrel equipment. Thicker wires require more coating material per unit length, and smaller barrel equipment requires increased line loads, impacting efficiency. Therefore, power coating operations often require multiple devices to handle coating a variety of wire diameters in diverse scenarios. Utility Model Content

[0031] See Figure 1 and Figure 4 , Figure 1 The schematic diagram of the coating robot is shown. Figure 4 A side view of a loading box 200 is shown. The present invention provides a coating robot comprising a base 100 and at least one loading box 200. The base 100 is provided with a first connector 110. The loading box 200 has a storage space capable of holding a glue can 240. A second connector 210 and a third connector 220 are provided on either side of the loading box 200. The second connector 210 is fixedly connected to the first connector 110. The third connector 220 has the same structure as the first connector 110 and is used to fixedly connect another loading box 200 to the third connector 220.

[0032] In the above embodiment, the first connecting member 110 and the second connecting member 210 are in a mating relationship, such as a nut, a screw, a buckle, and a slot, and the third connecting member 220 has the same structure as the first connecting member 110. Thus, two mating members are installed on both sides of the loading box 200. When more loading boxes 200 are needed, the assembly is completed by simply connecting the next loading box 200 to the third connecting member of the previous loading box 200 through the first connecting member 110. When disassembly is required, it is also convenient.

[0033] Compared with the prior art, the coating robot in the present invention has the following beneficial effects: the present application can load more glue tanks 240 through multiple loading boxes 200 that can be detachably connected to each other, so that the coating robot provided by the present application can adaptively load suitable coating glue according to the thickness and length of the cable, thereby increasing applicability and convenience. In addition, multiple loading boxes 200 can load various types of coating glue to meet more coating needs.

[0034] See Figure 2 , Figure 2 The structure and mating relationship of the first connector 110 and the second connector 210 are illustrated. In one embodiment, the first connector 110 is a hook comprising a first section 111 and a second section 112. One end of the first section 111 is vertically fixedly connected to the base 100, and the other end of the first section 111 is vertically connected to one end of the second section 112. The second section 112 is parallel to the base 100. The first section 111, the second section 112, and the base 100 enclose a limiting cavity. The second connector 210 comprises a fixed portion 211 and a rotating portion 212. The fixed portion 211 is fixedly connected to the loading box 200, and the rotating portion 212 is rotatably connected to the fixed portion 211. The rotating portion 212 is provided with a box latch 213, which is rotatably connected to the rotating portion 212. The loading box 200 is held against the base 100. The rotating part 212 rotates, and the box buckle 213 can pass through the second section 112 and enter the limiting cavity. The rotating part 212 rotates in the opposite direction, and the box buckle 213 is held against the side of the first section 111 away from the base 100. The third connecting member 220 ( Figure 2 The first section 111 in the embodiment (not shown) is fixedly connected to the same side of the loading box 200 where the fixing portion 211 is connected, and the limiting cavity enclosed by the third connecting member 220 and the loading box 200 opens toward the second connecting member 210.

[0035] Specifically, in the above embodiment, the first and second connectors 110 and 210 are respectively configured as a hook and a case latch assembly that cooperates with the hook, both of which are relatively common mechanically detachable connectors. The third connector 220, like the first connector 110, is also a hook, except that the third connector 220 is mounted on the end of the loading case 200 facing away from the base 100, allowing the first connector 110 of the next loading case 200 to connect to it.

[0036] In other embodiments, as mentioned above, bolt connection or snap connection can also be used. The hook and box buckle 213 structure provided in this application is convenient and fast to achieve detachable connection, and the connection effect is better.

[0037] Preferably, since the loading box 200 is mostly a rectangular parallelepiped and has one surface that fits with the base 100, the second connector 210 is located on two opposite sides of the fitting surface. Two second connectors 210 are provided on each of these two opposite sides, and four first connectors 110 are provided at corresponding positions on the base 100, making the connection more stable. Similarly, four third connectors 220 are also provided on the other end of the two opposite sides of the loading box 200 that face away from the base 100. Of course, if the connection method is a bolt connection, holes can be opened on the fitting surface or on the side. There are many bolt connection methods, which will not be elaborated in detail here.

[0038] See Figure 3 , Figure 3 The structure of the female connector 230 of the carrying case 200 is shown. In one embodiment, the base 100 is equipped with a male connector. Because the male connector is located below the base 100, the male connector is not shown in the accompanying drawings. However, the structure of the male connector can be clearly understood based on the illustration. The mating surface of the carrying case 200 and the base 100 is equipped with a female connector 230 that mates with the male connector. A male connector with the same structure is also installed on the side of the carrying case 200 facing away from the mating surface.

[0039] Specifically, the male connector and the female connector 230 primarily serve as position limiters, facilitating the connection between the first connector 110 and the second connector 210, as well as the connection between the loading boxes 200 and the loading boxes 200. Furthermore, when the first connector 110 and the second connector 210 are configured as hooks and latches 213, slight relative displacement between the loading box 200 and the base 100 is unavoidable. The cooperation between the male connector and the female connector 230 prevents this from occurring.

[0040] Specifically, the male connector is structured as a plurality of limiting posts protruding from the mating surface of the base 100, while the female connector 230 is a limiting slot provided on the mating surface of the base 100. When connecting, the loading box 200 is first placed against the base 100 so that the limiting posts are inserted into the limiting slots of the female connector 230, thereby achieving positional positioning. The rotating portion 212 on the second connector 210 is then rotated so that the box buckle 213 can bypass the second section 112 on the first connector 110 and face away from one end of the second connector 210, thereby entering the limiting cavity. The rotating portion 212 is then rotated in the opposite direction so that the box buckle 213 cannot escape from the limiting cavity, thus achieving a fixed connection between the base 100 and the loading box 200. To disassemble, the rotating portion 212 is rotated again so that the box buckle 213 can escape from the limiting portion.

[0041] See Figure 4 In one embodiment, it further includes an extrusion assembly 300, which includes a driving member ( Figure 4 The push plate 310 is located in the loading box 200 and is connected to the transmission assembly. The driving member is connected to the transmission assembly, and the driving member pushes the push plate 310 to move back and forth in the loading box 200 through the transmission assembly. Figure 4 The push plate 310 is located on the back of the transmission assembly and is therefore not shown. The movement of the push plate 310 squeezes the coating adhesive from the adhesive tank 240 in the loading box 200, thereby applying the coating adhesive to the surface of the high-voltage cable via the coating assembly on the base 100. The structure of the coating assembly can be referenced to existing technologies. The coating structure of the coating robot provided in this application is similar to or shares the same principles as existing ones.

[0042] Preferably, in one embodiment, the driving member is a motor, and the transmission assembly includes a push rod 320 and a transmission gear 330. The motor's output shaft is fixedly connected to the transmission gear 330, the push rod 320 meshes with the transmission gear 330, and the push plate 310 is fixedly connected to one end of the push rod 320. The motor can be remotely operated, is compact, and has stable output power, making it suitable for stably delivering coating adhesive during the uniform travel of the coating robot. The gear transmission offers stable coordination, a long service life, and flexible transmission ratio settings, making it well-suited to the operating mode of the coating robot.

[0043] Preferably, in one embodiment, a glue tank 240 is further included. The glue tank 240 is configured to be housed in the loading box 200. The glue tank 240 is used to store the coating glue. The glue tank 240 is disposable. Disposable glue tanks 240 are relatively low in cost. After a single application, the entire glue tank 240 can be directly replaced, facilitating quick glue replacement and improving production efficiency. The loading box 200 is divided into two layers, each layer being capable of holding a glue tank 240, which is convenient for mixing different chemical substances.

[0044] See Figure 1 In one embodiment, a plurality of loading boxes 200 are provided, and the plurality of loading boxes 200 are divided into two groups, one loading box 200 in each group is fixedly connected to the base 100, and the remaining loading boxes 200 are fixedly connected to the loading boxes 200 fixedly connected to the base 100. Multiple groups of extrusion assemblies 300 are provided, and each corresponds to the plurality of loading boxes 200.

[0045] In the above embodiment, the loading boxes 200 are located on both sides of the base 100, with the center section used for inserting cables to achieve optimal balance on the cables. The glue tanks 240 on the left and right sides of the base 100 can be loaded with different chemicals, allowing the left and right extrusion assemblies 300 to mix and use different chemical ratios at different extrusion speeds. Similarly, multiple glue tanks 240 can support the application of two-component materials. Using a mixing head, the two coating adhesives are instantly mixed after extrusion, achieving the effect of mixing multiple components.

[0046] Preferably, see Figure 4 In one embodiment, the transmission gear 330 is a planetary reduction gear set, which includes a main gear and a pinion gear. The main gear is fixedly connected to the output shaft of the motor. Multiple pinions are provided and mesh with the main gear. The pinions mesh with the push rods 320 in a one-to-one correspondence. The planetary reduction gear set can amplify torque and reduce speed, achieving high torque with a small motor, reducing the overall weight of the product, and lowering costs.

[0047] See Figure 1 and Figure 4 In one embodiment, a handle 321 is provided on the end of the push rod 320 facing away from the push plate 310, and a stop switch 340 is provided on the side of the shell wrapping the transmission gear 330 facing away from the loading box 200. The maximum distance between the stop switch 340 and the handle 321 is equal to the maximum distance that the push plate 310 moves in the loading box 200. When the handle 321 touches the stop switch 340, the motor is turned off.

[0048] Specifically, the stop switch 340 is electrically connected to the motor. When the stop switch 340 is pressed, the motor automatically shuts down, stopping the movement of the push plate 310. Of course, a worker can also remotely shut down the motor in advance, for example, when the coating glue has not yet been used up or the coating work has been completed. When the handle 321 touches the stop switch 340, it proves that the push plate 310 has reached its maximum travel distance and the coating glue in the glue tank 240 has been completely used up.

[0049] In the above embodiment, the stop switch 340 may also be installed on a side of the loading box 200 close to the handle 321 .

[0050] See Figure 1 In one embodiment, it further includes an equipotential device 400, which is installed on the side of the box away from the base 100. The equipotential device 400 is configured to contact the cable to achieve equipotential between the cable and the coating robot.

[0051] Specifically, the equipotential device 400 includes an equipotential rod and a return member. One end of the equipotential rod is a contact end, and the other end is a connection end. The connection end is used to rotate with the main body of the coating robot, and the contact end is used to contact the cable. The return member is fixedly connected to the main body and is driven by the connection end. The return 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. The coating robot provided in this application has two sets of equipotential devices 400. The equipotential rods in the equipotential device 400 are arranged in a cross-shaped manner to ensure that the cable can contact the equipotential rods.

[0052] In the above embodiment, the restoring component is mainly a spring. The equipotential rod rotates under the thrust of the cable, thereby deforming the spring to generate elastic force. When the thrust of the cable disappears, the spring drives the equipotential rod to reset.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
