[0041] The following is combined with Figure 1-8 The present application is further described in detail. An embodiment of the present application discloses a contact line burr removal device.

[0042] Reference Figure 1 and Figure 2As shown, during use, the contact wire 110 is fixedly mounted on the busbar, and a pair of plug-in boards 100 extend downward from the bottom end of the busbar, and the grooves on both sides of the contact wire 110 just correspond to the plug-in boards 100, so that the two plug-in boards 100 are inserted into the grooves to fix the contact wire 110. During use, the contact wire 110 will form barbs and flash on the cylindrical surface of the bottom side. Example

[0043] Reference Figure 3 As shown, a contact line burr removal device includes a base 300, a scraper 200, an elastic component 400 and a guide component 600. The scraper 200 is movably connected to the base 300, that is, the scraper 200 can move in directions on the base 300, including but not limited to horizontal, vertical and inclined directions. The scraper 200 is provided with a blade 210 for removing burrs and flash on the contact line 110. The elastic component 400 is arranged between the base 300 and the scraper 200 to provide a certain support force to the scraper 200 during use, so as to ensure that the scraper 200 is always in close contact with the surface of the contact line 110 during use. The guide component 600 is arranged between the base 300 and the scraper 200 to guide the scraper 200 during movement to ensure its stability during movement.

[0044] The base 300 is used to connect with the devices during its use, including but not limited to traction devices, support mechanisms, pushing devices, etc. The base 300 is provided with a connector 700 for interconnecting with the above devices, and the connector 700 includes but is not limited to hooks, connecting ears and other structures.

[0045] In the embodiment of the present application, the connecting member 700 refers to a connecting hole that penetrates the base 300, and the axis direction of the connecting hole is perpendicular to the running direction of the base 300 during use. In this way, it can be connected to the traction device, support mechanism, and pushing device by threaded connection, or connected to the corresponding device by connecting an extension bolt rod or other structures.

[0046] Reference Figure 4 and Figure 5 As shown, the elastic component 400 includes a spring 430, the base 300 is provided with two limit grooves 420 with openings facing upward, and the blade 200 is provided with two positioning grooves 410 corresponding to the limit grooves 420 on the side corresponding to the base 300. When the blade 200 slides and moves on the base 300 during use, its limit groove 420 is arranged opposite to the positioning groove 410.

[0047] The number of springs 430 can be adaptively increased according to the needs of the base 300 and the blade 200. In the embodiment of the present application, there are two springs 430. One end of the spring 430 is embedded in the limiting groove 420, and the other end of the spring 430 is embedded in the positioning groove 410.

[0048] In this way, during use, by fixing the base 300 on the traction device, the supporting mechanism, and the pushing device, the scraper 200 corresponds to the contact line 110. When the contact line 110 is worn inconsistently or the base 300 moves in a direction away from the contact line 110 under the drive of the traction device, the supporting mechanism, and the pushing device, the blade 210 of the scraper 200 is pressed against the contact line 110 under the action of the spring 430.

[0049] Secondly, during the installation process, the blade 210 of the blade 200 can be first pressed against the required working surface of the contact line 110, and then one end of the spring 430 can be installed in the limiting groove 420, and then the other end of the spring 430 can be placed in the positioning groove 410, and finally the base 300 can be fixedly installed on the traction device, the supporting mechanism, the pushing device, etc. In this process, the spring 430 is in a compressed state.

[0050] The spring 430 has equivalent substitutes, including but not limited to rubber, and materials that can achieve support and telescopic output.

[0051] Reference Figure 4 and Figure 5 As shown, a slide groove 640 is provided on the base 300, and the slide groove 640 is provided above the limiting groove 420 and is connected to the limiting groove 420, that is, the limiting groove 420 is provided at the bottom surface of the slide groove 640. The blade 200 is slidably provided in the slide groove 640, and the sliding direction is consistent with the expansion and contraction direction of the spring 430, and both are perpendicular to the moving direction of the blade 200 during use.

[0052] A through slot 610 is provided through the side wall of the base 300, and the centerline direction of the through slot 610 is perpendicular to the expansion and contraction direction of the spring 430, and is also perpendicular to the direction of movement of the blade 200 during use. A waist-shaped slot 630 is provided on the blade 200, which is opposite to the through slot 610, and the waist-shaped slot 630 is always relatively connected to the through slot 610 during the movement of the blade 200. That is, when the blade 200 moves upward to the maximum distance under the action of the spring 430, the upper arc edge of the waist-shaped slot 630 is aligned with the arc edge of the through slot 610, and when the blade 200 is squeezed by the contact line 110 and moves downward toward the base 300, the lower arc edge of the waist-shaped slot 630 is aligned with the arc edge of the through slot 610.

[0053] The guide assembly 600 includes a positioning pin 620, which passes through the through slot 610 and the waist-shaped slot 630 in sequence. That is, during the installation process, the spring 430 is embedded in the positioning slot 410 and the limiting slot 420, and then the blade 200 is squeezed to make the spring 430 in a compressed state, and then the positioning pin 620 passes through one side of the through slot 610, and then passes through the waist-shaped slot 630 and then passes through the other side of the through slot 610. In this way, the blade 200, the spring 430 and the base 300 are assembled in advance, the assembly strength during on-site use is reduced, and the installation and use during use are facilitated.

[0054] The waist groove 630 is provided to ensure that the scraper 200 can move within a certain range during use, so as to clean the contact wires 110 with different degrees of wear. At the same time, the positioning pin 620 cooperates with the waist groove 630 to limit the scraper 200, so as to prevent the blade 210 of the scraper 200 from being too close to the contact wire 110 and causing excessive damage to the contact wire 110 by removing burrs.

[0055] The guide assembly 600 further includes a guide column 660 , which is fixedly mounted on the base 300 . The positioning pins 620 thereof can be arranged in pairs, namely, on both sides of the positioning column, so as to ensure the stability of the blade 200 during use.

[0056] The blade 200 is provided with a guide groove 650, and the guide post 660 is inserted into the guide groove 650 during the installation process, and the side wall of the guide post 660 contacts the side wall of the guide groove 650. In this way, during the movement of the blade 200, the guide post 660 is slidably arranged relative to the guide groove 650, thereby improving the smoothness of the blade 200 during the movement process, and at the same time improving the connectivity between the blade 200 and the base 300.

[0057] The guide column 660 includes but is not limited to threaded connection, welding, and being integrally disposed on the base 300 .

[0058] In this embodiment, the guide column 660 is preferably provided integrally with the base 300, and the slide groove 640 is provided on both sides of the guide column 660. The communication hole is provided through the guide column 660.

[0059] Reference Figure 4 and Figure 5 As shown, the blade portion 210 is opened at the front end of the scraper 200 along the moving working direction, so that during use, the blade portion 210 at the front end just abuts against the contact line 110 and better removes burrs and flash on the contact line 110 during the moving process.

[0060] The blade portion 210 is arranged in a U shape and is adapted to match the outer shape of the contact wire 110, that is, when the blade portion 210 contacts the contact wire 110, the blade portion 210 just surrounds the contact wire 110 from the side away from the patch panel. Therefore, during use, the blade portion 210 just completes half-surrounding the burrs on the contact wire 110, thereby facilitating removal.

[0061] The blade portion 210 is tilted based on the moving direction of the blade 200 , and the tilt angle range is between zero and one hundred and eighty degrees.

[0062] In this embodiment, preferably, the blade portion 210 is set upward at a 45-degree angle in the first quadrant, with the midpoint of the connection between the blade 200 and the blade 200 as the origin, taking the direction of the blade 200 as the basic line. In this way, during use, the middle position of the inclined blade portion 210 will preferentially contact the burrs on the side wall of the contact line 110, and remove them as the blade 200 moves. When the burrs move from the contact line 110 during the removal process, they will move along the edge of the inclined angle, and tilt downward under the action of the blade 200, gradually forming a removal guide effect, achieving a removal action, and thereby enhancing its removal effect.

[0063] Reference Figure 4 and Figure 5 As shown, the side wall of the scraper 200 is provided with a receiving groove 220 for receiving the contact wire 110, the receiving groove 220 is arranged on the same side as the blade portion 210, and the receiving groove 220 is horizontally penetrated along the moving direction of the scraper 200. That is, the blade portion 210 is arranged at the notch of the receiving groove 220.

[0064] The receiving groove 220 is arranged as a columnar groove, and the radial size of the receiving groove 220 may be smaller than the radial size of the contact line 110 , so as to guide the burrs and flash cut by the blade portion 210 .

[0065] In this embodiment, the radial size of the receiving groove 220 is set to be equal to the size of the contact line 110, that is, the scraper 200 moves horizontally in the direction of travel, and the contact line 110 is set in the receiving groove 220, thereby ensuring the stability of the scraper 200 during horizontal movement and improving the scraper 200 The effect of removing burrs. Example

[0066] The difference between this embodiment and the first embodiment is that the diameter of the receiving groove 220 is different.

[0067] Reference Figure 6 and Figure 7 As shown,

[0068] In this embodiment, the radial size of the receiving groove 220 is larger than the radial size of the contact line 110. By setting the diameter of the receiving groove 220 larger than the diameter of the contact line 110, during use, it is only necessary to make the U-shaped blade portion 210 face the contact line 110, so that the blade portion 210 can remove the burrs that the blade portion 210 contacts under the action of the spring 430. In this way, it is not necessary to remove the burrs at the contact line 110 corresponding to the receiving groove 220 on the blade 200 when installing the removal device. The burrs at this location will not block the receiving groove 220 and the blade portion from pressing against the contact line 110, and the on-site assembly strength is further reduced.

[0069] At the same time, the receiving groove 220 is larger than the radial size of the contact line 110, and its removal device can remove burrs and flash from linear and tubular structures of different thicknesses in the same and adjacent areas.

[0070] Reference Figure 7 and Figure 8 As shown, at least one set of limiting components 500 is fixedly arranged on the blade 200, and each set of limiting components 500 includes two limiting members 510 symmetrically arranged on both sides with the length center of the receiving slot 220 as the axis. The number of limiting components 500 can be increased according to the length of the blade 200 in the direction of travel.

[0071] The stopper 510 is fixedly mounted on the side wall of the blade 200, and the side walls on both sides of the receiving groove 220 are inclined. The stopper 510 is perpendicular to the side wall of the blade 200, and the stopper 510 is threadedly connected and fixed on the blade 200. Each stopper 510 is provided with a bearing 520.

[0072] The bearing 520 can change its radial size so that its outer circumferential wall abuts against the side wall of the contact line 110 or the side wall of the plug board 100. Thus, the bearings 520 on both sides of the receiving groove 220 form a limit for the scraper 200 and ensure the stability of the scraper 200 during the movement, thereby preventing the scraper 200 from shaking during the movement due to the excessive size of the receiving groove 220. Example

[0073] The difference between this embodiment and Embodiment 1 and Embodiment 2 lies in the connection method of the blade portion 210 .

[0074] In the first and second embodiments, the blade portion 210 and the scraper blade 200 are integrally provided.

[0075] In this embodiment, the blade portion 210 is configured as a U-shaped blade and is fixedly installed at the front end of the scraper 200 in the moving direction by means of threaded connection or clamping. The above connection method facilitates the removal and replacement of the scraper.

[0076] The drawings of the specification do not show the connection method between the scraper 200 and the blade portion 210 .

[0077] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
