Description

Technical Field

[0001] This utility model specifically relates to a main cable strand spray marking device. Background Technology

[0002] In infrastructure construction fields such as bridge engineering and large cableways, the main cable strands, as core load-bearing components, directly determine the overall structural safety and assembly efficiency of the project through their processing precision. Main cable strands typically require fixed-length markings during the factory prefabrication stage according to design drawings. This ensures accurate cutting and splicing during subsequent on-site construction, guaranteeing that each strand's length matches and preventing uneven stress or assembly errors due to length deviations.

[0003] For example, Chinese patent application CN104960991A provides a cable conveyor for fixed-length spray marking, including a frame, rollers for winding cables on the frame, an output side of the cable on one side of the frame, a meter counter installed on the output side, the meter counter being connected to a control device, and an electric spray gun on the frame, the control device being connected to the electric spray gun. This device can mark cables over a certain length and also has the advantages of being able to set and count.

[0004] However, existing marking devices, when marking cables to a fixed length, result in relative motion between the cable and the fixed spray gun during transport. This relative motion prevents the paint sprayed from forming precise dotted or short-segment marks on the cable strand surface, instead creating elongated strips of marking along the transport direction. Subsequent construction workers struggle to accurately pinpoint the start and end boundaries of the markings when identifying the cable strand length, easily leading to errors in length judgment. This results in the cable strands being cut too long or too short, affecting on-site assembly progress and structural stability, while also making the markings unclear. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model proposes a main cable strand spray marking device to solve the technical problem mentioned in the background art: when marking cables to a fixed length, the cable and the fixedly installed spray gun are in relative motion during the transportation process, resulting in a long marking distance on the cable. This makes it difficult for workers to accurately identify the length of the cable during subsequent use, and the marking is not clear enough.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a main cable strand spray marking device, comprising: A base, on which a return cylinder and a trolley are provided, and the main cable is placed above the trolley via a conveying device; Multiple sets of spraying components are arranged circumferentially along the main cable axis, and all are mounted on the pulley. A connecting assembly, disposed on the trolley, is selectively connected to or disconnected from the main cable in the transport state; and A drying component is disposed on one side of the base.

[0007] In a preferred embodiment, the spraying assembly includes: The pressure tank is fixedly mounted on the trolley; and Multiple sets of spray guns are arranged circumferentially along the main cable axis, and all are mounted on the trolley and connected to the pressure tank via solenoid valves.

[0008] In a preferred embodiment, the trolley is further provided with an isolation component, the isolation component comprising: The first pneumatic finger is fixedly mounted on the base; and The partitions are provided in at least four sets, and are fixedly installed on the two sets of output ends of the first pneumatic finger in pairs. The two sets of partitions are closed to form a hole for the main cable to pass through. The spray gun is arranged between the two sets of partitions that are spaced apart.

[0009] In a preferred embodiment, the connection component includes: The second pneumatic finger is fixedly mounted on the base; and The clamps are provided in two sets and are respectively fixedly installed on the two sets of output ends of the second pneumatic finger, and the main cable is located between the two sets of clamps.

[0010] In a preferred embodiment, the drying assembly includes: A hot air dryer is installed on one side of the base; and A drying cylinder is installed on the hot air dryer and connected to it through an air inlet pipe, and the main cable passes through the drying cylinder.

[0011] In a preferred embodiment, the side wall of the drying cylinder is provided with an air outlet, and the air outlet and the air inlet pipe are arranged in a staggered manner along the axis of the drying cylinder.

[0012] In a preferred embodiment, the drying cylinder includes: Carbon steel pipes are installed on the hot air dryer; A stainless steel pipe is installed inside the carbon steel pipe, and insulation cotton is filled between the stainless steel pipe and the carbon steel pipe; and The shielding rings are provided in two sets, and both are fixed to both ends of the carbon steel pipe by flanges.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The device has a wire feeding reel and a winding machine on both sides, which transport the main cable on the device. When the main cable needs to be marked, it can be selectively fixed to the main cable for a certain period of time through the connecting component, which drives the trolley to move on the base with the main cable. This keeps the spraying component and the main cable relatively stationary, avoiding excessive marking distance caused by relative movement, improving the accuracy of the operator's identification of the cable length, and making the marking clearer. The circumferentially arranged spraying component can spray the main cable from multiple directions. With the help of the drying component, the marking can be dried in time. After marking is completed, the connection between the connecting component and the main cable is disconnected, and the trolley is reset by the return cylinder to prepare for the next marking.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0017] Example: like Figure 1 , 2As shown, this utility model provides a main cable strand spray marking device, including a base 1, a return cylinder 9 and a trolley 2 mounted on the base 1. The main cable is placed above the trolley 2 via a conveying device. A wire feeding reel and a winding machine can be installed on both sides of the base 1 to convey the main cable, allowing it to pass over the trolley 2. Multiple spraying components are arranged circumferentially along the main cable axis on the trolley 2. Each spraying component includes a pressure tank 7 fixedly mounted on the trolley 2. Multiple spray guns 8 are mounted on the trolley 2, arranged circumferentially along the main cable axis, and connected to the pressure tank 7 via a solenoid valve. The solenoid valve can be controlled to activate the spray guns 8, causing them to spray paint from the pressure tank 7 onto the main cable to form a mark.

[0018] like Figure 1 , 2 As shown, in this embodiment, the trolley 2 is also equipped with an isolation component. The isolation component includes a first pneumatic finger 5 fixedly mounted on the base 1. Multiple sets of partitions 6 are provided on both output ends of the first pneumatic finger 5. Each pair of partitions 6 closes to form a hole for the main cable to pass through. The spray gun 8 is positioned between two spaced-apart partitions 6. By controlling the first pneumatic finger 5 to activate and drive the multiple sets of partitions 6 to close, the spraying area is enclosed, preventing paint from spraying outside the main cable and forming clear marking segments.

[0019] like Figure 1 , 2 As shown, in this embodiment, the trolley 2 is provided with a connecting component, which can selectively connect or disconnect the main cable in the conveying state. The connecting component includes a second pneumatic finger 3 fixedly installed on the base 1. Both output ends of the second pneumatic finger 3 are provided with clamps 4, and the main cable is located between the two clamps 4.

[0020] When marking is required, the second pneumatic finger 3 can be activated to close the two sets of clamping plates 4, clamping the main cable and allowing the trolley 2 to move with the main cable. This ensures that the spray gun 8 and the main cable remain relatively stationary during the spraying process, resulting in a dotted or short-segmented spraying position and clearer markings. It is understood that in some embodiments, the first pneumatic finger 5 and the second pneumatic finger 3 can be SMC type MHZ2 series pneumatic fingers to achieve the opening and closing function of the two output ends. Furthermore, a recognition camera and supporting software can be added to the working area. The camera identifies the marking points on the standard wire, and the software controls the timing of the first pneumatic finger 5, the second pneumatic finger 3, and the solenoid valve based on the required adjustment amount for each marking point. This technique is common knowledge in the art and will not be elaborated further here. After marking is completed, the first pneumatic finger 5 and the second pneumatic finger 3 are opened, and the solenoid valve is closed. Subsequently, the return cylinder 9 is activated to reset the trolley 2, ready for the next marking.

[0021] like Figure 1 ,3 As shown, in this embodiment, a drying assembly is provided on one side of the base 1. The drying assembly includes a hot air dryer 10 disposed on one side of the base 1. A drying cylinder is disposed on the hot air dryer 10 and connected to it by an air inlet pipe 11. The main cable passes through the drying cylinder. When the main cable passes through the drying cylinder, it can be dried by the hot air dryer 10 to facilitate subsequent winding of the main cable. An air outlet 15 is provided on the side wall of the drying cylinder. The air outlet 15 and the air inlet pipe 11 are staggered along the axis of the drying cylinder, so that hot air can circulate in the drying cylinder for a certain period of time.

[0022] like Figure 3 , 4 As shown, in this embodiment, the drying cylinder includes a carbon steel pipe 14 mounted on the hot air dryer 10. A stainless steel pipe 12 is installed inside the carbon steel pipe 14, and insulation cotton 13 is filled between the stainless steel pipe 12 and the carbon steel pipe 14 to increase the insulation effect and thus improve the drying efficiency. Both ends of the carbon steel pipe 14 are also equipped with shielding rings 16 connected by flanges 17. A shielding ring 16 with a suitable aperture can be selected for installation to reduce the gap between the main cable and the shielding ring 16, thereby reducing hot air leakage.

[0023] The specific usage and beneficial effects of this utility model are as follows: The device has a wire feeding reel and a winding machine on both sides, which allows the main cable to be transported on the device. When the main cable needs to be marked, it can be selectively fixed to the main cable through the connecting component for a certain period of time, which drives the trolley 2 to move on the base 1 to follow the main cable. This keeps the spraying component and the main cable relatively stationary, avoiding excessive marking distance caused by relative movement, improving the accuracy of the staff in identifying the cable length, and making the marking clearer. The circumferentially arranged spraying component can spray the main cable from multiple directions. With the help of the drying component, the marking can be dried in time. After marking is completed, the connection between the connecting component and the main cable is disconnected, and the trolley is reset by the return cylinder 9 to prepare for the next marking.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above. Modifications or improvements can be made to this utility model, which is obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of this utility model fall within the scope of protection claimed by this utility model.
