[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] This invention provides a mobile printing robot for moving around cement poles, such as... Figure 1As shown, the device includes a main body 1 and a printer 2 for spraying and printing on a cement pole 10; the main body 1 and the printer 2 are detachably connected; the main body 1 is provided with at least one surrounding component 3 for surrounding and holding the cement pole 10; the surrounding component 3 is detachably connected to the main body 1; the surrounding component 3 is provided with a receiving and holding area 4 for accommodating the cement pole 10; the output end of the printer 2 extends into the receiving and holding area 4 to complete the spraying and printing operation.

[0024] Furthermore, the device body 1 includes: a placement member 5 and a connector 6 for connecting to the printer 2; the placement member 5 is detachably connected to the printer 2; one end of the placement member 5 is fixedly connected to the connector 6; and the other end of the connector 6 is hinged to the surrounding assembly 3.

[0025] Specifically, the device body 1 includes a placement member 5 for supporting and connecting the printer 2, and a connecting member 6 for supporting and connecting; as shown in the figure. Figure 2 As shown, the placement component 5 is a plate-shaped or frame structure made of metal or high-strength engineering plastic. The upper part is provided with an interface for connecting to the connector 6. This connection can be welded, bolted, or integrally formed to form a fixed connection. In this embodiment, the bolted connection method is selected. The lower part is provided with a mechanism for connecting to the printer 2, which adopts bolt and screw hole connection. The connector 6 is fixedly connected to the placement component 5 to form a stable base. The upper end is hinged to the surrounding component 3 through a hinge, pivot, or hinge. In this embodiment, such a surrounding hinge is selected. The hinged connection allows the surrounding component 3 to have a certain opening and closing angle relative to the printer 2 during installation, making it easier to hug or detach from the cement pole 10. It also allows the device to make adaptive fine adjustments when encountering uneven ground, ensuring that the printhead of the printer 2 always maintains the ideal height and angle.

[0026] Further, the surrounding component 3 includes: a first surrounding ring 7, a second surrounding ring 8, and a fixing member 9 for connecting and fixing the first surrounding ring 7 and the second surrounding ring 8; one end of the first surrounding ring 7 is hinged to the connecting member 6; one end of the second surrounding ring 8 is hinged to the connecting member 6; one end of the fixing member 9 is detachably connected to the other end of the first surrounding ring 7, and the other end of the fixing member 9 is detachably connected to the other end of the second surrounding ring 8; when the fixing member 9 is simultaneously connected to the first surrounding ring 7 and the second surrounding ring 8, the first surrounding ring 7 and the second surrounding ring 8 cooperate to form the receiving and clamping area 4.

[0027] Specifically, such as Figure 2As shown, the surrounding component 3 is a split-encircling structure, mainly consisting of a first ring 7 and a second ring 8. The two rings are physically independent. One end of the first ring 7 and the second ring 8 are connected to both sides of the connector 6 by hinge. In the initial state, the two rings can be opened like a door. The free ends of the first ring 7 and the second ring 8 are connected by the fastener 9. In this embodiment, a strap is used for connection. In other embodiments, quick-release pins, bolts and nuts and buckles can be used for locking. After the fastener 9 connects the free ends of the first ring 7 and the second ring 8, the first ring 7 and the second ring 8 together form a complete rigid ring structure around the cement rod 10, that is, they cooperate to form the clamping area 4.

[0028] Furthermore, both the first ring 7 and the second ring 8 are composed of a plurality of first auxiliary surrounding members 71 and a plurality of second auxiliary surrounding members 81 arranged in sequence at intervals; adjacent plurality of first auxiliary surrounding members 71 and a plurality of second auxiliary surrounding members 81 are hinged to form the structure of the first ring 7 and the second ring 8.

[0029] Specifically, such as Figure 2-3 As shown, the first ring 7 and the second ring 8 adopt a modular, chain-like design to achieve adjustable diameter. Specifically, they are composed of multiple first auxiliary rings 71 and multiple second auxiliary rings 81 connected end to end in sequence through hinge points at their ends, like a chain. The sequential arrangement is represented as one first auxiliary ring 71 - one second auxiliary ring 81 - one first auxiliary ring 71 - one second auxiliary ring 81, and so on, until the required length is reached. The modular unit configuration allows for adjustments to the overall circumference of the ring by increasing or decreasing the number of surrounding components, thereby expanding or shrinking the diameter of the clamping area 4. This enables it to perfectly accommodate various specifications of concrete poles 10, ranging from thinner communication poles to thicker power poles.

[0030] Further, the first auxiliary surrounding member 71 includes: a first support frame 711 and a first driven wheel 712; both ends of the first support frame 711 are provided with first connecting pins 713; the middle part of the first support frame 711 is provided with a first mounting groove 714; a first wheel axle is provided in the first mounting groove 714; the first driven wheel 712 is disposed in the first mounting groove 714 and is rotatably connected to the first wheel axle.

[0031] Specifically, such as Figure 3As shown, the first support frame 711 is the main structure, made of metal stamping or casting, and has sufficient strength; the first connecting pins 713 are fixed to both ends of the support frame, serving as hinge shafts; the first mounting groove 714 is located in the middle of the support frame, and is a U-shaped or concave structure, used to accommodate the first driven wheel 712; the first wheel axle is a metal pin, with both ends fixed in the shaft holes on both sides of the mounting groove 714; the first driven wheel 712 is a pulley, sleeved on the first wheel axle, and can rotate freely around it, and can be made of nylon, rubber or metal, with patterns designed on the outer surface to increase friction.

[0032] Further, the second auxiliary surrounding member 81 includes: a second support frame 811 and a second driven wheel 812; both ends of the second support frame 811 are provided with second connecting pins 813; the second support frame 811 is connected to each other by first connecting pins 713 and second connecting pins 813 to realize the first support frame 711 and the second support frame 811 being hinged to each other; a second mounting groove 814 is provided in the middle of the second support frame 811; a second wheel axle is provided in the second mounting groove 814; the second driven wheel 812 is disposed in the second mounting groove 814 and is rotatably connected to the second wheel axle.

[0033] Specifically, such as Figure 3 As shown, the second support frame 811 has a similar structure to the first support frame 711 and serves as the core load-bearing component. Two second connecting pins 813 are located at both ends of the second support frame 811. When connecting adjacent first support frames 711 and second support frames 811, the pin holes of the first connecting pin 713 and the second connecting pin 813 are aligned, and they are connected and fixed by a pin. In this embodiment, bolt pins 11 are used for disassembly. Figure 3 As shown, it is further fixed by screwing in; the functions and structures of the second mounting groove 814, the second wheel axle, and the second driven wheel 812 are exactly the same as the corresponding parts of the first auxiliary surrounding part 71, and together they play the role of support and rolling.

[0034] Further, the connecting member 6 includes: a first support rod 61, a second support rod 62, and a support member 63; the first support rod 61 and the second support rod 62 are detachably connected to the placement member 5; one end of the support member 63 is hinged to the first support rod 61, and the other end of the support rod is hinged to the second support rod 62; the first support rod 61 is hinged to the first retaining ring 7; the second support rod 62 is hinged to the second retaining ring 8; the first support rod 61, the second support rod 62, and the support member 63 cooperate to form a spray nozzle 64 for the output end of the printer 2 to extend out for spray printing.

[0035] Specifically, such as Figure 2As shown, the first support rod 61 and the second support rod 62 are two parallel uprights, the lower ends of which are connected to the two sides of the placement component 5 by bolts to achieve detachability. Each rod is provided with several annular hinge slots, which are used to hinge with the surrounding component 3. The support component 63 is a horizontal rod, the two ends of which are connected to the upper ends of the first support rod 61 and the second support rod 62 by hinge shafts, thus forming a strong triangular stable structure between the two. The structure greatly enhances the rigidity of the entire device body 1, prevents it from shaking when pushing the surrounding column, and ensures printing accuracy. The area enclosed by the first support rod 61, the second support rod 62 and the support member 63 naturally forms a huge spray nozzle 64; the nozzle of the printer 2 is located at the spray nozzle 64, ensuring that the spraying field of the nozzle is unobstructed and can spray the cement pole 10 without obstruction.

[0036] Furthermore, the bottom of the placement component 5 is provided with a plurality of mounting holes 53 for connecting and fixing the printer 2 and the placement component 5; strip-shaped blocks 51 are respectively provided on both sides of the placement component 5; the two strip-shaped blocks 51 and the placement component 5 cooperate to form a placement groove 52 for placing the printer 2.

[0037] Specifically, multiple through holes are made on the base plate of the placement part 5, and the positions of these through holes correspond precisely to the positions of the threaded holes reserved on the bottom of the printer 2 housing; by using bolts to pass through the mounting holes 53 and screw them into the threaded holes of the printer 2, the two are firmly fixed together to achieve a detachable rigid connection. On both sides of the plate of the placement component 5, a raised rectangular strip block is fixed; these two strip blocks 51 and the bottom plate of the placement component 5 together form a placement groove 52; when installing the printer 2, the bottom of the printer 2 is first placed into the placement groove 52, and the strip blocks 51 can quickly guide and position and restrict the movement of the printer 2 on the horizontal plane, ensuring that the mounting hole 53 can be accurately aligned, and also increasing the torsional strength after connection.

[0038] Furthermore, the printer 2 is provided with a handle 21 for personnel to grip; a switch button 22 is provided on the inside of the handle 21.

[0039] Specifically, such as Figure 1 As shown, the handle 21 is integrated into the upper part of the printer 2 housing. Its shape is ergonomically designed for easy gripping and carrying with one or two hands, facilitating the handling and operation of the device. The switch button 22 is located on the inside of the handle 21, i.e., the side facing the operator. This layout allows the operator to easily and comfortably reach and press the button with their fingers when naturally holding the handle 21, enabling the printing to start and stop. This is intuitive and enhances safety and convenience.

[0040] Furthermore, a control display screen 23 is provided on the side of the printer 2.

[0041] Specifically, the control display screen 23 is an LCD or OLED touch screen, located on the side of the printer 2. This screen is used to: display device status, such as battery level, ink level, and connection status; set printing parameters such as print density and size; input and edit the content to be printed, such as text, numbers, patterns, QR codes, etc.; provide operation menus and fault prompts; through this display screen, users can complete all settings directly on-site without relying on additional external equipment, greatly enhancing the independence of the equipment and operational efficiency.

[0042] In the specific implementation process, such as Figure 4 As shown, during operation, firstly, according to the diameter of the target cement pole 10, assemble an appropriate number of surrounding parts to form a first surrounding ring 7 and a second surrounding ring 8; push the equipment toward the cement pole 10 so that the cement pole 10 enters the space semi-enclosed by the first surrounding ring 7 and the second surrounding ring 8, that is, the receiving clamping area 4; then use the fixing parts 9 to lock the free ends of the first surrounding ring 7 and the second surrounding ring 8 so that the equipment is stably clamped onto the cement pole 10. At this time, all driven wheels are in contact with the surface of the cement pole 10. The content to be printed is set on the control display screen 23 of the printer 2; the operator holds the handle 21 of the printer 2, turns on the switch button 22 to start printing, and then only a slight tangential force is applied to push the device, and the entire device can easily rotate 360 ​​degrees around the cement pole 10 under the rolling of the driven wheel; during this process, the nozzle of the printer 2 continuously sprays paint onto the surface of the cement pole 10 through the spray nozzle 64, completing a seamless circular printing operation; after printing is completed, the fixing part 9 is disconnected, and the entire device can be removed from the cement pole 10, completing the printing and spraying operation of the cement pole 10.

[0043] This invention discloses a mobile printing robot for cement poles, featuring a compact overall structure, convenient installation, adaptability to cement poles 10 of different diameters, and automated circular spraying printing. The modularly designed surrounding component 3 allows for diameter adjustment by adding or removing units, accommodating various specifications of cement poles 10 and exhibiting high versatility. The device integrates a dedicated printer 2, requiring only manual assistance to automatically complete high-quality, standardized circular printing around the pole, far exceeding the efficiency of manual labor. Driven wheels on the surrounding component 3 enable easy rotation around the pole, and the hinged connection structure allows the device to adapt to uneven ground installation environments, further increasing its adaptability to various scenarios.
