Description

Technical Field

[0001] The invention relates to the field of line coating, and in particular to a sealing and pressurizing device of a line coating robot. Background Art

[0002] Line coating is a technology that moves on old overhead lines and coats and sets insulating materials on the outside of the lines at the same time, thereby completing the line transformation without replacing them. In the line coating process, the coating tape must first be guided to wrap around the line, and then the overlapping positions on both sides of the coating tape are heated to melt and connect, and then the coating tape is heated and melted as a whole. After cooling again, it can be tightly wrapped on the outer surface of the line to ensure that the insulation layer is firm and reliable. For the melting connection link at the overlapping position of the coating tape, part of the melted tape residue will stick to the heating area. After long-term accumulation, it is easy to block the melting chamber and make its cross-sectional profile irregular, which will lead to an increase in the movement resistance of the coating equipment and a decrease in the uniformity of the coating tape wrapping, which will affect the working reliability of the line insulation layer. At the same time, if the bonding at the overlapping position of the coating tape is not smooth enough, groove defects will also be formed on the surface of the insulation layer, causing its tensile strength, wear resistance and other properties to decrease.

[0028] The present invention will be further described below in conjunction with the accompanying drawings.

[0029] like Figure 1-2 As shown, a sealing and pressurizing device for a line coating robot comprises a sealing unit 1 and a pressurizing unit 2 which are sequentially arranged along the line relative to the moving direction of the coating robot; Figure 3-4 As shown, the sealing unit 1 includes a first molding member 11 and a second molding member 12; the first molding member 11 and the second molding member 12 are buckled together to form a molding cavity 13; the first molding member 11 includes a first limiting body 111 and a heating component 112; the heating component 112 is detachably connected to the first limiting body 111; the front end of the heating component 112 extends into the molding cavity 13, corresponding to the position where the two sides of the circuit outer coating strip are folded and overlapped; the second molding member 12 includes a second limiting body 121; the second limiting body 121 is opposite to the heating component 112 in the buckling direction; a receiving groove 101 is arranged on the inner side of the second limiting body 121; the front end of the heating component 112 is correspondingly arranged in the receiving groove 101; the heating surface of the heating component 112 is higher than the edge of the receiving groove 101.

[0030] Figure 1 The solid arrow in the figure indicates the moving direction of the coated line 6 relative to the coating robot, and the line passes through the wrapping guide 5, the sealing unit 1 and the pressurizing unit 2 in sequence; while the dotted arrow indicates the moving direction of the coated strip 7, which is continuously released from the storage device in the coating robot and its surface is wrapped synchronously with the penetration of the line. The wrapping process is shown in FIG. Fig. 9 As shown, after passing through the wrapping guide 5, the cross section of the wrapping tape 7 is guided into a U-shape by the gradually shrinking inner cavity of the wrapping guide 5. When the U-shaped curled wrapping tape 7 continues to pass into the forming cavity 13, its two sides will further move closer to each other and overlap on the top of the coated line 6. The overlapping position is melted in the heating area of ​​the heating component 112 to achieve connection. At this point, the wrapping tape 7 is completely wrapped around the surface of the coated line 6.

[0031] In addition, reference Fig.10, through the structure of the accommodating groove 101, it is equivalent to setting an inner concave space on the inner wall of the forming cavity 13, and a gap is left between the front end of the heating component 112 and the inner wall of the accommodating groove 101; when the overlapping position of the coated strip 7 is heated, the melted part of the strip close to the coated circuit 6 is squeezed flat by the heating component 112, and a small amount of melted part of the strip that is raised due to the overlapping thickening is cut off by the heating component 112 while hot, and the cut-off part will be squeezed into the gap between the heating component 112 and the accommodating groove 101 by the subsequent coated strip, and adhere to the upper surface of the front end of the heating component 112 or the inner wall of the accommodating groove 101, that is, the heating component 112 plays a cutting role while melting the connecting strip; when the equipment needs to be cleaned and maintained later, the second limiting body 121 and the heating component 112 can be disassembled and processed separately; in this way, the residual heating area of ​​the overlapping raised excess strip can be avoided to hinder the passage of the subsequent coated circuit 6 and the coated strip 7.

[0032] like Figure 5 As shown, the second molded part 12 also includes a third limiting body 122; the third limiting bodies 122 are clamped on both sides of the second limiting body 121 in pairs; the third limiting bodies 122 are opposite to the first limiting body 111 in the snap-fit ​​direction; a temperature measuring groove 102 is provided on the outer surface of the second limiting body 121; a wiring groove 103 is provided on the outer surface of the third limiting body 122; the temperature measuring groove 102 is connected with the wiring groove 103.

[0033] The third limiting body 122 corresponds to the two ends of the molding cavity 13, and guides the coated circuit 6 and the coated strip 7 into the cavity through its own arc profile; the function of the temperature measuring groove 102 is that a temperature measuring device can be arranged in the groove. Because the distance between the groove and the inner wall of the molding cavity 13 is already very small, the temperature sensor can be installed in the groove and filled and covered with insulation materials such as glass fiber, rock wool, etc., while ensuring that the measured temperature has a reference value, so as to reduce the influence of the external environment on the measurement accuracy; the design of opening holes in the first molding part 11 and the second molding part 12 to embed the sensor is omitted, thereby ensuring the integrity of the heating and sealing chamber.

[0034] like Figure 5-6As shown, the heating component 112 includes a frame 104 and a heating plate 105; the heating plate 105 is located inside the accommodating groove 101; the frame 104 is connected and arranged between the first limiting body 111 and the heating plate 105; the frame 104 is fitted on the surface of the first limiting body 111; the frame 104 is provided with a first mounting hole 106 and a second mounting hole 107; the first mounting hole 106 is perpendicular to the fitting surface of the first limiting body 111; the second mounting hole 107 is parallel to the fitting surface of the first limiting body 111; a pin is embedded in the second mounting hole 107, and the side surface of the pin is in close contact with the first limiting body 111.

[0035] The frame 104 is assembled and connected with the reserved threaded hole on the first limit body 111 through the screw in the first mounting hole 106. However, because the heating plate 105 needs to be in contact with the coating strip all the time to receive the lateral thrust, the screw may easily become loose after long-term operation. Therefore, with the help of the pin in the second mounting hole 107, a limit can be formed in the direction of screw insertion and extraction, thereby greatly improving the installation firmness. At the same time, the pin and the second mounting hole 107 have an interference fit to ensure their own position stability. When the heating component 112 needs to be disassembled, the pin can be quickly pulled out, and then the screw can be unscrewed to remove the frame 104 together with the heating plate 105, and the disassembly and assembly are quick.

[0036] like Fig.11 As shown, the heating plate 105 includes a first plate 108 and a second plate 109; the second plate 109 is extended on the side of the first plate 108; the top height of the second plate 109 gradually increases along the line insertion direction; a height difference is set at the junction between the top contour of the second plate 109 and the top contour of the first plate 108.

[0037] As can be seen from the figure, the second sheet 109 is relatively thick, and it is convenient to insert a heating element inside it for heating, while the first sheet 108 has a smaller thickness to enhance the cutting effect, and the contour of the height change at the top of the first sheet 108 can further guide the small amount of coated strip that is cut off to transfer to the deep gap between the heating sheet 105 and the accommodating groove 101 under the push of the cutting action; the height difference between the first sheet 108 and the second sheet 109 can form a storage space similar to a step, allowing the coated strip to accumulate there first, and when the accumulated material is too much, it will continue to transfer and accumulate in the gap space corresponding to the top of the first sheet 108; this design of using the step difference to realize the stepped buffer space can preferentially gather the cut excess coated strip to the side of the heating sheet 105, so that it can be directly swept down with a brush during cleaning and maintenance. Only when the maintenance cycle is too long does it need to remove the heating component 112 for thorough cleaning, thereby simplifying the work of equipment cleaning and maintenance, shortening the maintenance time, and enhancing the ability of continuous operation.

[0038] like Figure 1-2 As shown, the pressurizing unit 2 is arranged downstream of the sealing unit 1; the line from the sealing unit 1 is correspondingly inserted into the pressurizing unit 2; the sealing unit 1 reciprocates along the line insertion direction, and correspondingly adjusts the distance between itself and the pressurizing unit 2.

[0039] The reciprocating movement of the sealing unit 1 can be achieved by means of screw transmission, electric telescopic rod push-pull and the like. The purpose of adjusting the distance between the sealing unit 1 and the pressurizing unit 2 is to allow the heated and sealed coated strip to cool to a suitable temperature, so as to facilitate further pressing and flattening by the pressurizing unit 2. The distance is specifically affected by factors such as the material of the coated strip and the ambient temperature, and can be adjusted on-site during the actual trial operation stage.

[0040] like Figure 7-8 As shown, the pressurizing unit 2 includes a pressure wheel group 3 and a buffer assembly 4; the buffer assembly 4 includes a spring pressure plate 41, a connecting plate 42 and a guide column 43; the spring pressure plate 41 is fixedly arranged above the pressure wheel group 3; the connecting plate 42 is connected to the pressure wheel group 3; the upper end of the guide column 43 is connected to the spring pressure plate 41, and the lower end is inserted through the connecting plate 42; a spring 44 is sleeved on the guide column 43; the spring 44 is connected and arranged between the spring pressure plate 41 and the connecting plate 42.

[0041] The pressure wheel group 3 falls under the action of gravity and presses on the sealing part of the coating strip passing through the sealing unit 1, further flattening it to ensure that the coating layer around the coated circuit is evenly distributed and has a continuous and smooth contour; the spring 44 is in a compressed state, which can further enhance the downward pressure of the pressure wheel group 3. At the same time, when the coating robot rises and falls at high altitude due to airflow and other factors, the pressure wheel group 3 can always keep in contact with the surface of the coating strip. The spring 44 is used to adapt to the change in the spacing between the spring pressure plate 41 and the connecting plate 42, provide vibration buffering, and improve the stability of the pressing action.

[0042] The pressure wheel assembly 3 includes a grooved part 31, a shaping wheel 32 and an inter-wheel support 33; the shaping wheels 32 are distributed along the line insertion direction; the grooved part 31 opens downward; the shaping wheel 32 is assembled on the grooved part 31; the lower end of the shaping wheel 32 is exposed to the outside of the grooved part 31 and is pressed tightly against the top of the line; the inter-wheel support 33 and the shaping wheel 32 are staggered on the grooved part 31; the bottom contour of the inter-wheel support 33 is aligned with the line contact surface of the shaping wheel 32.

[0043] When the shaping wheel 32 contacts the sealing position of the coating tape, its melted bonding position has not yet completely cooled. At this time, applying pressing pressure to it can make the contour of the sealing position smoother and the connection with the coating tape in other directions around the line more natural, reducing surface defects and improving the quality of wrapping protection; the shaping wheel 32 will also rotate while pressing, thereby significantly reducing the friction between itself and the coating tape by rolling, making the coating construction smoother and more energy-saving; the inter-wheel support 33 serves as a supplementary pressing between different shaping wheels 32, which can significantly improve the pressing effect of the coating tape over a certain distance, and the alternating sliding friction and rolling friction also effectively controls the overall friction resistance, reducing the impact on the overall mobility of the coating robot.

[0044] like Figure 8 As shown, the groove-shaped member 31 includes a fixed plate 301 and a baffle 302; the cross-section of the fixed plate 301 is an L-shaped structure; the baffle 302 is detachably connected to the fixed plate 301 to form a groove structure together; the two ends of the rotating shaft of the fixed wheel 32 are respectively connected to the fixed plate 301 and the baffle 302.

[0045] The groove part 31 is designed as a separate assembly structure, which can be easily disassembled, so that the shaping wheel 32 and the inter-wheel support 33 can be cleaned regularly to remove the solidified coating tape adhering to the surfaces of the two. At the same time, when the diameter of the coated line changes, the fixed plate 301 of different width specifications can be replaced, or a thickened pad can be added at the connection between the fixed plate 301 and the baffle 302 to change the width of the groove part 31, thereby adapting to the wider shaping wheel 32, and significantly improving the construction adaptability.

[0046] The baffle 302 is made of transparent material.

[0047] The baffle 302 is made of a transparent material such as an acrylic plate, so that the contact between the coated strip and the shaping wheel 32 can be easily observed and the installation position can be adjusted in time.

[0048] The shaping wheels 32 are V-shaped wheels; the inter-wheel support members 33 are filled and arranged between adjacent shaping wheels 32 .

[0049] The advantage of the V-shaped wheel is that it can use its own concave contact surface to adapt to the curved surface contour of the coated strip, thereby further improving the pressing effect and making the pressed part connect more smoothly with the surrounding strip part after it is completely cooled and shaped.

[0050] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
