Description

Technical Field

[0001] The utility model relates to the technical field of cable maintenance, in particular to a small coating robot. Background Art

[0002] In the prior art, electric power transmission mainly adopts the form of overhead lines, and most of the early planned distribution network lines are put into use in the form of bare conductors. Due to the low overhead height of the bare conductors of the distribution network, they are easy to contact with the growing trees year by year and the expanding buildings, resulting in short circuits, and there are many potential safety hazards. In order to improve the transmission safety, it is necessary to carry out insulation transformation on the old overhead bare conductors. The traditional insulation transformation method for overhead lines is to replace the whole bare conductor. This construction method requires a large area of power outage and needs to re-plan and erect poles. It is not only time-consuming, laborious and costly, but also has extremely low efficiency.

[0003] In order to reduce costs, at present, the method of spraying insulating materials is also used to maintain old cables, usually by manual spraying or machine spraying. However, manual spraying has the problems of low efficiency, high operation risk and poor consistency of spraying effect. Although machine spraying improves the spraying efficiency, the existing light coating robots are large in volume and heavy in weight, difficult to carry and transport, and cannot meet the coating requirements of medium and low voltage transmission lines below 10KV. If the existing heavy light coating robots are mounted on medium and low voltage transmission lines, the transmission lines are likely to break. Summary of the Utility Model

[0004] Aiming at the defects in the prior art, the purpose of the utility model is to provide a small coating robot, which has the functions of automatic walking and spraying, and can improve the cable maintenance efficiency.

[0005] The technical solution adopted by the utility model is: a small coating robot, including a walking unit and a coating unit. The walking unit includes an upper frame and a lower frame which are arranged up and down and the relative distance between them can be adjusted. A construction space is formed between the upper frame and the lower frame. Walking wheels and pressing wheels are respectively arranged at the lower end of the upper frame and the upper end of the lower frame. The coating unit includes coating molds which are detachably installed at the lower end of the upper frame and the upper end of the lower frame and are arranged oppositely. The coating molds are connected to a material cylinder for conveying insulating materials to the coating molds.

[0006] In this technical solution, the coating robot can be hung on the cable to be maintained to automatically carry out the coating of insulating materials. The upper frame of the device walking unit can be hung on the cable. By changing the distance between the two frames, the walking wheels and the pressure wheels are made close to the cable surface to ensure the stable movement of the walking unit. During the walking process, the barrel continuously outputs the insulating material and is coated on the cable surface through the coating mold, thereby achieving uniform coating construction of the cable during the continuous walking of the robot. Compared with manual construction, not only is the construction automation degree high and the operation risk is reduced, but the construction efficiency and quality are also significantly improved.

[0007] Preferably, a travel motor module for driving travel wheels is provided in the upper frame.

[0008] Preferably, a screw module adapted to the thread of the lower frame is provided in the upper frame, and the screw module is transmission-connected to a clamping motor module.

[0009] Preferably, arc grooves are provided on the opposite end surfaces of the coating dies arranged on the upper frame and the lower frame.

[0010] Preferably, the coating die input end is provided with a material pipe connected to the barrel output end.

By changing the distance between the two frames, the walking wheels and the clamping wheels are made close to the cable surface to ensure the stability of the movement of the walking unit. During the walking process, the barrel continuously outputs the insulating material and is coated on the cable surface through the coating mold, thereby achieving uniform coating construction of the cable during the continuous walking process of the robot. Compared with manual construction, not only the construction automation degree is high, the operation risk is reduced, and the construction efficiency and quality are significantly improved; it has high practical value.

Detailed implementation manners

[0020] Hereinafter, embodiments of the technical solution of the present utility model will be described in detail with reference to the accompanying drawings. The following embodiments are only used to illustrate the technical solution of the present utility model more clearly, and thus are only examples and should not be used to limit the protection scope of the present utility model.

[0021] It should be noted that unless otherwise specified, the technical terms or scientific terms used in this application should have the ordinary meanings understood by those skilled in the art to which the present utility model belongs.

[0022] As Figures 1 to 3 shown, a specific embodiment of the present utility model provides a small coating robot, which can automatically perform the coating operation of insulating materials on cables; it includes a walking unit and a coating unit, wherein the walking unit includes an upper vehicle frame 100 and a lower vehicle frame 200 that are arranged up and down and the relative distance between them is adjustable. A construction space is formed between the upper vehicle frame 100 and the lower vehicle frame 200. A walking wheel 300 and a pressing wheel 400 are respectively provided at the lower end of the upper vehicle frame 100 and the upper end of the lower vehicle frame 200; the coating unit includes a coating die 500 that is detachably installed at the lower end of the upper vehicle frame 100 and the upper end of the lower vehicle frame 200 and is arranged oppositely, and the coating die 500 is connected with a material cylinder 600 that conveys insulating materials to the coating die 500.

[0023] As Figures 1 to 3As shown, through the above settings, the coating robot provided in this embodiment can be suspended on the cable to be maintained to automatically perform the coating work of the insulating material. The upper frame 100 of the walking unit of the device can be hung on the cable. By changing the distance between the two frames, the walking wheels 300 and the pressing wheels 400 are closely attached to the cable surface to ensure the stability of the movement of the walking unit. During the walking process, the material cylinder 600 continuously outputs the insulating material, which is coated on the cable surface through the coating die 500, so as to realize the uniform coating construction of the cable during the continuous walking of the robot. Compared with manual construction, not only the degree of construction automation is high, the operation risk is reduced, but also the construction efficiency and quality are significantly improved.

[0024] As described above, in this embodiment, the walking wheels 300 are provided to fit the cable and rotate so that the robot can move along the cable. In this embodiment, a walking motor module 700 for driving the walking wheels 300 is provided in the upper frame 100. The walking motor module 700 is used to drive the walking wheels 300 so that the robot can move automatically or stop automatically. In addition, in order to realize the automatic control of the distance between the upper frame 100 and the lower frame 200, a lead screw module 800 that is threadedly adapted to the lower frame 200 is provided in the upper frame 100, and the lead screw module 800 is drivingly connected to a pressing motor module 900. By driving the lead screw module to rotate by the rotation of the pressing motor, the distance between the upper frame 100 and the lower frame 200 can be adjusted. When the distance is reduced, the pressing wheels 400 and the walking wheels 300 can be closely attached to the cable surface to ensure that the robot can move stably guided by the cable and avoid falling. In practical applications, the model and specifications of the motor module can be selected according to needs, and the control is realized through the corresponding control circuit, which will not be elaborated here.

[0025] As Figure 1 As shown, in this embodiment, arc-shaped grooves are also provided on the opposite end faces of the coating die 500 provided on the upper frame 100 and the lower frame 200. In this way, the arc-shaped grooves can surround the cable surface, so that the insulating material ejected from the die can be evenly attached to the cable surface.

[0026] In this embodiment, the material cylinder 600 needs to transport the insulating material to the position of the coating die 500 and then eject it. In practical applications, a material pipe 1000 connected to the output end of the material cylinder 600 is provided at the input end of the coating die 500. In addition, in order to output the insulating material in the material cylinder 600, a piston 1100 capable of extruding the insulating material is provided in the material cylinder 600. A sealing ring 1200 and a sealing ring 1300 are provided on the outer periphery of the piston 1100. The material cylinder 600 is also connected to an air pump 1400 for driving the piston 1100 to move through an air duct 1500. In this way, when the air pump 1400 operates, it can drive the piston 1100 to move so that the insulating material is extruded. Since the surface of the piston 1100 has a sealing material, the output effect of the insulating material can be improved.

[0027] AsFigures 1 to 3 As shown, when using this device, in order to hang the robot on the cable, the upper carriage 100 in this embodiment is connected with an insulating rod 1600, and a hand-held section is provided at the lower end of the insulating rod 1600. At the same time, a fixing frame 1700 arranged up and down is provided on the outer periphery of the cartridge 600, and the fixing frame 1700 is fixedly connected with the insulating rod 1600. In this way, the insulating rod 1600 facilitates technicians to hang the robot on the cable or remove it from the cable after construction, and the cartridge 600 is fixed on the insulating rod 1600 by using the fixing frame 1700 to ensure the stability of the installation of the cartridge 600. This device should also be provided with a corresponding controller for controlling the operation of each device. The controller can be connected to a control panel for easy operation by technicians, and the relevant control structure will not be elaborated here.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered by the scope of the claims and the description of the present invention.
