Description

Technical Field

[0001] The utility model relates to a rail transit contact line repair device, in particular to an intelligent contact line full-automatic repair device. Background Art

[0002] The rigid contact network is mainly composed of overhead rigid busbars, contact wires, support and positioning devices, insulating components, overhead ground wires, etc. Due to its simple structure, no tension on the contact wires, no worries about disconnection, and easy maintenance, it is widely used in subway tunnel sections, that is, most of the major subway tunnel sections in China use rigid contact network for power supply.

[0003] During the mutual sliding friction between the contact wire and the carbon slide plate, the mechanical friction between the contact wire and the carbon slide plate will cause defects such as burrs, sharp corners, and burrs on the friction surface of the contact wire and the arc of the contact wire. In terms of electrical performance, defects such as burrs, sharp corners, and burrs may cause increased local discharge, affect the stability and reliability of current transmission, and may even cause electrical failures. In terms of mechanical properties, burrs, sharp corners, and burrs are prone to cause scratches and wear when the pantograph carbon slide plate passes, which may damage the carbon slide plate and further aggravate the damage to the contact wire, affecting the service life of the contact network. In addition, burrs may also affect the appearance and neatness of the contact wire to a certain extent. To solve the defects of burrs, sharp corners, and burrs on the contact wire, it is usually necessary to take appropriate milling, grinding, and finishing measures. However, when the current grinding and milling equipment processes the arc surface of the contact wire, it is difficult to process the arc surface during processing, and its upper and lower adjustment structure has a complex structure.

The positioning wheel assembly 30, the milling cutter assembly 40, the polishing wheel assembly 50, and the traveling wheel assembly 60 are all mounted on the bottom plate 12 between the two side plates 11. And the traveling wheel assembly 60 is disposed at the foremost side, the polishing wheel assembly 50 is disposed at the rear side, and the positioning wheel assembly 30 and the milling cutter assembly 40 are disposed between the traveling wheel assembly 60 and the polishing wheel assembly 50.

[0028] In this embodiment, four groups of the balance wheel assemblies 20 are provided, and two groups are provided on each of the two side plates 11, and the two groups of balance wheel assemblies 20 are arranged in one-to-one correspondence. The balance wheel assembly 20 includes a main body portion 21, a fixing seat 22, and a buffer spring 23. A top plate 13 is provided inside the top of the side plate 11. The fixing seat 22 is installed on the top plate 13 by bolts. A fixing hole is provided on the bottom surface of the fixing seat 22. The main body portion 21 is mounted in the fixing hole. A limiting hole 24 is provided on the outer surface of the fixing seat 22. The limiting hole 24 is arranged in a "C" shape and includes a connecting hole, a first extension hole, and a second extension hole that are communicated with each other. The first extension hole and the second extension hole both extend outward, and the length of the first extension hole is longer than that of the second extension hole.

[0029] The main body part 21 includes a balance wheel 211, a connecting shaft 212, and a flange 213. Both ends of the connecting shaft 212 are connected to the balance wheel 211 and the flange 213. The balance wheel 211 is arranged on the inner side, and the flange 213 is arranged on the outer side. The buffer spring 23 is arranged between the fixed seat 22 and the flange 213. A limiting post 214 is also arranged on the outer surface of the connecting shaft 212, and the limiting post 214 extends into the limiting hole 24. During use, when the limiting post 214 is moved to be clamped in the second extension hole, at this time, the balance wheel 211 moves towards the middle and moves to the bus bar step 101 of the rigid catenary 100, which can play the role of hanging the balance device. When the limiting post 214 is moved to the outer end of the first extension hole, at this time, the balance wheel 211 moves towards the outside away from the rigid catenary 100, and the balance wheel 211 can be removed from the bus bar step, so as to facilitate the disassembly of the device.

[0030] The running wheel assembly 60 includes a mounting seat 61, a mounting rod 62, running wheels 63, a quick-release handle 64, and a driving device 65. Both ends of the running wheels 63 are pivotally connected to the mounting seat 61. The driving device 65 is arranged on the outside of the mounting seat 61 and can drive the running wheels 63 to rotate to move forward. In this embodiment, the driving device 65 is a motor. The mounting rod 62 is arranged on the bottom surface of the mounting seat 61. The quick-release handle 64 is installed at the bottom end of the mounting rod 62, located below the bottom plate 12 and can rotate along the mounting rod 62. The quick-release handle 64 is installed on the mounting rod 62 through a rotating shaft. In this embodiment, the quick-release handle 64 is an eccentric structure. There are two relatively arranged near sides and far sides on the quick-release handle 64. The near side is the side where the mounting axis is closest to the quick-release handle 64, and the far side is the side farther from the rotating shaft. When the near side of the quick-release handle 64 rotates to one side of the mounting rod 62, at this time, the dimension of the mounting rod 62 extending on the bottom plate 12 is longer, and it supports the running wheels 63 to move upward to contact the rigid catenary 100 for running back and forth. When the far side of the quick-release handle 64 rotates to one side of the mounting rod 62, at this time, the mounting rod 62 below the bottom plate 12 is longer, and the mounting rod 62 extending above the bottom plate 12 is shorter, so that the running wheels 63 are lowered and the farthest from the rigid catenary 100.

[0031] The positioning wheel assembly 30 includes a positioning base 31, a positioning wheel 32, a mounting rod 33, and a quick-release handle 34.

The quick-release handle 34 is pivotally connected to the other end of the mounting rod 33, and the quick-release handle 34 can rotate relative to the mounting rod 33. The quick-release handle 34 has the same shape and structure as the quick-release handle 64. When the near side of the quick-release handle 34 is rotated to the side of the mounting rod 33, the positioning wheel 32 contacts the contact wire. Conversely, when the far side of the quick-release handle 34 is rotated to the side of the mounting rod 33, at this time, the positioning wheel 32 is separated from the contact wire. In this embodiment, two sets of front and rear positioning wheel assemblies 30 are provided.

[0032] The milling cutter assembly 40 includes a middle mounting frame 41, two milling cutter devices 42 and a limit wheel device 43 arranged above the middle mounting frame 41. In addition, a bottom mounting rod is provided at the bottom of the middle mounting frame 41, and a quick-release handle is provided at the bottom end of the bottom mounting rod. The quick-release handle has the same structure as the aforementioned quick-release handle, so it will not be described in detail here. In this embodiment, the limit wheel device 43 is arranged between the two milling cutter devices 42. The milling cutter device 42 includes a milling cutter seat 421, a track limit plate 422, a mounting block 423, a milling cutter 424, and a lower driving device 425. The milling cutter seat 421 is installed on the middle mounting frame 41. The track limit plate 422 is arranged outside the milling cutter seat 421. The lower driving device 425 and the milling cutter 424 are both installed in the mounting block 423, and the lower driving device 425 is arranged below the milling cutter 424.

[0033] Two vertically arranged limiting through holes 4221 are provided on the trajectory limiting plate 422. The limiting through holes 4221 are arc-shaped, and the arc extension direction of the through holes 4221 extends from bottom to the upper inner side. A lower extension column 4251 is provided on the lower driving device 425, and the lower extension column 4251 extends into the corresponding limiting through hole 4221. An upper extension column 4231 is provided on the mounting block 423 above the extension column 4251, and the upper extension column 4231 extends into the corresponding upper limiting through hole 4221. During operation, the lower driving device 425 moves inward and rotates gradually, so that the extension column 4251 moves upward along the limiting through hole 4221 from bottom to top. The lower limiting column 4231 pushes the mounting block 423 to rotate forward and upward at a certain angle, and the mounting block 423 drives the milling cutter 424 to rotate and move forward and upward in an arc. A rotary driving device is further provided at the rear side of the milling cutter 424, and the rotary driving device drives the milling cutter 424 to rotate for processing. In this embodiment, the milling cutters 424 of the two milling cutter devices 42 are arranged facing each other, and the combined movement routes of the two milling cutters 424 moving upward from bottom form a lower semi-circle, which can respectively process the bottom end and the side arc surface of the contact wire. Specifically, the left milling cutter 424 processes the arc surface at the lower right of the contact wire, and the right milling cutter 424 processes the arc surface at the lower left of the contact wire.

[0034] The limiting wheel device 43 includes a limiting base 431 and a limiting wheel 432 arranged in the limiting base 431. The outer surface of the limiting wheel 432 is flat, which can improve the accuracy of alignment. When its top contacts the bottom end of the contact wire, the upper surface of the milling cutter 424 contacts the contact wire. In this embodiment, the limiting wheel 432 is used to limit the position of the milling cutter 424 to prevent the milling cutter 424 from being too far away from the contact, resulting in a poor processing effect; or being too close to the contact wire, causing the milling cutter 424 to mill too much of the contact wire.

[0035] The polishing wheel assembly 50 includes a positioning seat 51, a driving motor 52, a polishing wheel 53 and a tension spring 54. The bottom end of the positioning seat 51 is pivotally connected to the bottom plate 12. The driving motor 52 and the polishing wheel 53 are both installed on the positioning seat 51, and the driving motor 52 drives the polishing wheel 53 to rotate through a transmission belt. A number of mounting holes 511 are provided on one side of the positioning seat 51. The number of mounting holes 511 is arranged in an arc. One end of the tension spring 54 is hung in the mounting hole 511, and the other end is installed on the bottom plate 12. During operation, by hanging the tension spring 54 in different mounting holes 511, the position of the polishing wheel 53 can be adjusted.

[0036] In this embodiment, four quick-release handles are provided, which are respectively arranged at the bottom of the bottom plate 12 and are respectively connected to the balance wheel assembly 20, two positioning wheel assemblies 30 and the milling cutter assembly 40. A compression spring is further arranged between each assembly and the bottom plate. Before work, the balance wheel 211 on the balance wheel assembly 20 is moved inward so that the balance wheel 211 extends to the busbar step of the rigid catenary 100 to hang the balance device. Then, the quick-release handle is rotated to move each part of the whole mechanism upward, so that the positioning wheel assembly 30, the milling cutter assembly 40, the polishing wheel assembly 50 and the running wheel assembly 60 can achieve precise positioning on the rigid catenary 100 and the contact wire. During work, the equipment is started, and the running wheel assembly 60 drives the equipment to move forward. The milling cutter 424 of the milling cutter assembly 40 moves along the semi-circular limit through hole 4221 on the track limit plate 422, so that the milling cutter 424 only mills the corner of the contact wire and does not mill other positions. The polishing wheel assembly 50 polishes the contact wire after milling to improve the repair quality.

[0037] In addition, the intelligent contact wire full-automatic repair equipment further includes a remote control device. The control device can be a controller such as a mobile phone, a remote control, a computer, etc., and can control the running speed, start, stop, etc. of the equipment according to requirements.

[0038] To sum up, the intelligent contact wire full-automatic repair equipment of the present invention can realize milling and grinding repairs on defects such as burrs, sharp corners, and flash on the bottom surface and corner positions of the contact wire, which can not only improve the repair efficiency, reduce the manpower requirement, but also improve the repair quality. In addition, the installation and disassembly of the whole equipment are relatively simple, and the alignment is relatively flexible. Each component can be adjusted up and down through the quick-release handle respectively. For example, when milling is not required, the milling cutter assembly 40 can be moved downward; other components are in the normal working position; the flexibility is good. The present invention has strong practicability and has strong popularization significance.

[0039] The above embodiments only represent one implementation mode of the present invention, and the description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
