[0036] In order to make the purpose, technical solution and advantages of the invention more clearly understood, the invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the invention and are not used to limit the invention.

[0037] like Figures 1 to 18 As shown, the present invention provides a modular repair device 100 for a rigid contact network, which includes a detection milling device 10, a grinding and polishing coating device 20 and a main control device (not shown in the figure). The detection milling device 10 and the grinding and polishing coating device 20 are both mounted on the contact network and arranged in sequence front and back, and the main control device is respectively connected to the detection milling device 10 and the grinding and polishing coating device 20 by signal.

[0038] The detection and milling device 10 includes a first mounting frame 11 and a first driving assembly 12, a first driven assembly 13, a scanning assembly 14, and a milling assembly 15 installed in the first mounting frame 11.

[0039] The first mounting frame 11 includes a first bottom plate 111 and first side plates 112 disposed on both sides of the first bottom plate 111, the first driving assembly 12 is mounted on the first bottom plate 111, and the first driven assembly 13 is mounted on the first side plate 112. The second mounting frame 21 includes a second bottom plate 211 and second side plates 212 disposed on both sides of the second bottom plate 211, the second driving assembly 22 is mounted on the second bottom plate 211, and the second driven assembly 23 is mounted on the second side plate 212. The first mounting frame 11 also includes an adjustment plate 113, an adjustment rail 111a is disposed on the first bottom plate 111, the adjustment rail 111a extends along the arrangement direction of the two first side plates 112, the adjustment plate 113 is mounted on the adjustment rail 111a and can move along the adjustment rail 111a, and the milling assembly 15 is mounted on the adjustment plate 113. The first bottom plate 111 with a slide rail structure and the adjustment plate 113 can be adjusted and slidable, so that the milling assembly 15 installed thereon can be adjusted at any time to accurately correspond to the contact line.

[0040] The first drive assembly 12 and the second drive assembly 22 have the same structural design, and both include a support rod 121, a drive frame 122, a drive wheel 123, a drive motor 124 and a first telescopic spring 125. The support rod 121 is mounted on the first bottom plate 111 and the second bottom plate 211, the drive frame 122 is mounted on the upper end of the support rod 121, the drive wheel 123 and the drive motor 124 are both mounted on the drive frame 122, and the drive motor 124 is connected to the drive wheel 123 by power. The first telescopic spring 125 is sleeved on the support rod 121 and its two ends are respectively against the bottom plate and the drive frame 122, and the support rod 121 can be flexibly adjusted relative to the first bottom plate 111 and the second bottom plate 211. The first drive assembly 12 and the second drive assembly 22 can provide driving power for the detection milling device 10 and the grinding and polishing coating device 20 respectively, so that the two can travel along the contact network and perform continuous repair operations on the contact line at the same time. Compared with manual drive, the automated drive structure is not only more reliable, but also has more precise and uniform speed control.

[0041] The first driven assembly 13 and the second driven assembly 23 also have the same structural design, and both include a plurality of driven devices 131, and a driven wheel 132 is arranged inside the driven device 131. The plurality of driven devices 131 are evenly installed on the first side plate 112 and the second side plate 212. A handle 133 is also arranged outside the driven device 131, and one handle 133 is arranged outside each of the two driven devices 131. The first driven assembly 13 and the second driven assembly 23 can respectively engage and install the detection milling device 10 and the grinding and polishing coating device 20 on the contact network, so that they can smoothly move along the contact network for operation.

[0042] The scanning component 14 includes a front contour scanning camera 141 and a rear contour scanning camera 142, which are respectively arranged on the front and rear sides of the milling component 15. Before milling repair, the contour scanning camera on one side will scan and detect the surface contour of the contact line, and cooperate with the main control device to accurately mill and repair the defects of the contact line. After the milling repair, the contour scanning camera on the other side will scan and detect the surface contour of the contact line again to confirm the milling repair effect of the contact line. If there are still defects, the milling component 15 will be milled again to ensure that all defects on the surface of the contact line can be repaired in the end.

[0043] The milling assembly 15 includes two milling devices 151, and the milling device 151 includes a milling motor 151a, a milling frame 151b and a forming milling cutter 151c. The milling motor 151a is installed on the mounting frame, the milling frame 151b is installed on the milling motor 151a, and the forming milling cutter 151c is installed on the inner side end of the milling frame 151b. The forming milling cutters 151c of the two milling devices 151 are arranged opposite to each other. The forming milling cutter 151c is arranged in a truncated cone that gradually becomes smaller from the inner side end to the free end, and the connecting surfaces at both ends are arc surfaces. Specifically, in this embodiment, the two forming milling cutters 151c are arranged opposite to each other left and right and staggered front and back.

[0044] During milling, the forming milling cutter 151c is first adjusted to the position so that the forming milling cutter 151c corresponds to the two sides of the contact line, and then the milling motor 151a drives the forming milling cutter 151c to rotate at a high speed, and the forming milling cutters 151c on both sides perform milling repair on both sides of the contact line. The two sets of independent milling structures perform automatic milling repair on both sides of the contact line respectively, which can freely deal with different wear defects on both sides of the contact line, and the final milling repair effect can be greatly improved.

[0045] The grinding assembly 24 includes a grinding frame (not shown), a grinding wheel 241 and a grinding motor (not shown), wherein the grinding wheel 241 is mounted on the grinding frame, and the grinding motor drives the grinding wheel 241 to rotate. The polishing assembly 25 includes a polishing frame (not shown), a polishing wheel 251 and a polishing motor (not shown), wherein the polishing wheel 251 is mounted on the polishing frame, and the polishing motor drives the polishing wheel 251 to rotate. Specifically, in this embodiment, the material of the grinding wheel 241 is non-metallic materials such as nylon and fiber, and the material of the polishing wheel 251 is cotton cloth, felt, fiber, etc. with better elasticity.

[0046] During the grinding process, the grinding motor and the polishing motor drive the grinding wheel 241 and the polishing wheel 251 respectively to grind and polish the contact line surface in sequence. Both sets of motors use brushless motors, which not only have high power, but also have low vibration and noise problems during operation. In addition, the speed at which the polishing motor drives the polishing wheel 251 is faster than the speed at which the grinding motor drives the grinding wheel 241, thereby ensuring that the contact line surface after grinding and polishing is smoother.

[0047] The coating assembly 26 includes a coating frame 261 and a coating wheel 262. The coating frame 261 is mounted on the mounting frame, and the coating wheel 262 is mounted on the coating frame 261 and rotates. The coating wheel 262 is made of graphite. The coating wheel 262 made of graphite will also roll and rub against the contact wire synchronously when the device moves, thereby coating the surface of the contact wire with a layer of graphite. The graphite layer can not only play a lubricating role, but also enhance the anti-oxidation ability of the contact wire to a certain extent.

[0048] The monitoring component 27 includes an industrial camera 271, which is installed on the second bottom plate 211 and is connected to the industrial control host by signal. The main control device includes a PLC control device (not shown), an industrial control host (not shown) and an interactive terminal (not shown). The PLC control device, the industrial control host and the interactive terminal are connected by signal in sequence, wherein the PLC control device is also connected by signal to the first drive component 12, the second drive component 22, the milling component 15, the grinding component 24 and the polishing component 25, and the industrial control host is also connected by signal to the scanning component 14 and the monitoring component 27.

[0049] In the process of controlling the operation of the repair equipment, the main control device first sets the relevant operating parameters through the interactive terminal and sends them to the industrial control host unit. After receiving the operating parameters, the industrial control host unit will further send a control command to the PLC control unit, and the PLC control unit will control the repair equipment to start working. When the repair equipment mills, grinds and polishes the contact line, the scanning component 14 first detects the contour data of the scanned contact line surface and feeds it back to the industrial control host unit. Then the industrial control host unit sends an adjustment command to the PLC control unit based on the scanned data. Finally, the PLC adjusts the drive component, milling component 15, grinding component 24, etc. to adjust the milling position, milling feed amount, and grinding and polishing strength. In addition, the working status of each component in the milling repair process, the contact line parameters scanned by the scanning component 14, and the contact line image taken by the monitoring component will be uploaded to the industrial control host unit for storage and management, and will also be fed back by the industrial control host unit to the interactive terminal for real-time display to the operator.

[0050] The detection milling device 10 further includes a positioning assembly 16, and the positioning assembly 16 includes two positioning devices 161, and the two positioning devices 161 are respectively arranged on the front and rear sides of the milling device 151. The positioning device 161 includes a positioning frame 161a and a positioning wheel 161b, and the positioning frame 161a is arranged on the first bottom plate 111, and the positioning wheel 161b is arranged on the positioning frame 161a. During the process of the repair equipment performing milling repair, the positioning wheel 161b on the positioning assembly 16 always rolls along the contact line, thereby ensuring that the milling assembly 15 also installed on the adjustment plate 113 will not shake or deviate.

[0051] To sum up, the beneficial effects of a modular repair device 100 for a rigid contact network of the present invention are: by simultaneously integrating the milling processing and the grinding and polishing coating device 20, and cooperating with the main control device that automatically and intelligently controls the operation of each module, the repair equipment can perform comprehensive and efficient repair operations on the contact line; the scanning component 14 and the milling component 15 are used in the detection and milling device 10 to cooperate with each other, so that the milling processing of the contact line surface by the detection and milling device 10 is more accurate and reliable, and the forming milling cutter 151c in the milling component 15 is two groups of independent control and asymmetrical arrangement, so that both sides of the contact line can obtain the best milling and grinding effect; and the grinding component 24 and the coating component 26 in the grinding and polishing coating device 20 can successively grind and polish the surface of the contact line and coat it with a graphite coating, which can not only further repair the defects of the contact line itself, but also effectively improve the lubricity of the contact line surface, thereby protecting the contact line so that it can better contact and rub with the carbon slide plate; the present invention is highly practical and has a strong promotion significance.

[0052] The above-mentioned embodiment only expresses one implementation method of the invention, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the inventive concept, which all belong to the protection scope of the invention.
