Description

[0002] In the urban rail transit system, the pantograph of the subway vehicle is one of the key components of the electric traction system.

With the development of subway transportation and the increasing demand for operational efficiency and safety, higher standards are required for the maintenance and maintenance of the carbon slide plate.

[0003] The traditional chamfering machine can usually only perform R chamfering on one side of the carbon slide plate, which means that the maintenance personnel need to perform two independent operations on both sides of the carbon slide plate. Such a working method not only consumes time and effort, but also causes the single-side chamfering limit to be blocked due to the small gap between the one-pantograph-four-plate structure, making the chamfering operation more difficult. The one-pantograph-four-plate structure refers to the double-plate structure in the background art. Figure 2 In addition, using a traditional grinding machine or a hand file to chamfer will generate a large amount of metal dust, which will pose a threat to the health of the maintenance personnel if inhaled.

[0039] Embodiment one

[0040] Based on the problems mentioned in the background art, the application proposes a pantograph carbon slide plate double-side corner synchronous chamfering device, which mainly solves the synchronous chamfering problem of the two sides of the double carbon slide plate, and the too small spacing between the plates, which makes the traditional chamfering method more troublesome, and the dust is easy to accumulate between the plates. The advantage of this device is that it can chamfer the two sides of the carbon slide plate synchronously, and has dust collection function. As shown in Figure 1 , the scheme is as follows, including a shell 1, a driving mechanism installed in the shell 1, two chamfering heads 4 installed at the output end of the driving mechanism, and a dust collection mechanism connected with the driving mechanism, the specific content includes that the shell 1 at least includes a driving cavity 11 and a hand cavity 12 communicated with the driving cavity 11, both cavities adopt hollow cavity structure, multiple clamping parts are arranged inside for installing driving mechanism and dust collection mechanism and other structural parts, the end of the driving cavity 11 is provided with a polishing port 2, the output end of the driving mechanism is close to the polishing port 2, and two opposite chamfering heads 4 are installed, the shape of the chamfering head 4 is designed based on the preset chamfering requirement, and in this embodiment, the chamfering head 4 is arranged at the polishing port 2 based on the cross-sectional distance of the carbon slide plate. The improvement of this embodiment is that the dust collection mechanism is also assembled, and the dust collection mechanism realizes the dust collection function through the driving mechanism, that is, the dust collection is carried out at the same time of polishing, which can effectively reduce the inhalation of dust in actual use, and quickly collect the dust after chamfering to prevent accumulation between the plates.

[0041] In this embodiment, the specific shape of the chamfering head 4 is not described in detail, which is assembled and replaced based on actual needs.

[0042] In this embodiment, the polishing port 2 adopts a flat opening structure, which is similar to a flat duckbill structure, as shown in Figure 2 and Figure 4 , the lower half of the polishing port 2 is cut by a preset distance from the outermost cross section inward to form a local opening, that is, a shielding cover structure 5 with three continuous surfaces, the design of this scheme is that the cut space is used for polishing interval, and the polishing interval has an adjustable interval of at least 45° to 70° relative to the horizontal plane where the surface of the carbon slide plate is located, which meets the wrist comfort design of human.

[0043] In this embodiment, the bottom of the two side surfaces of the shielding cover structure 5 is chamfered, and the maximum cross-sectional area of the chamfering head 4 locally exceeds the side surface of the shielding cover structure 5. The design here is to enable the chamfering head 4 to be clamped between the double carbon slide plates to complete chamfering, and the working mode is referred to Figure 2 .

[0044] In order to better illustrate this embodiment, a specific driving structure is given in this embodiment, as shown in Figure 3As shown, including the installation of the two faces of the cover structure 5 bearing seat 71, through the bearing seat 71 rotating shaft 72, installed on the rotating shaft 72 first bevel gear, and with the first bevel gear 73 meshing second bevel gear 74, drive motor 75 drive rotating second bevel gear 74. Where the drive motor 75 through the drive cavity 11 installed, its fixed scheme can be achieved by a plurality of drive cavity 11 inside the card.

[0045] The dust collection mechanism in the embodiment as shown Figure 3 and Figure 5 As shown, including the dust suction port 3, suction pipe 81, collection tank 82, fan 83, air flow tank 84, the specific assembly of the above structure is not described in detail, all through the drive cavity 11 inside a plurality of card part fixed, not the core of the present application.

[0046] In this embodiment, the shell 1 adopts a detachable structure, the inside card part is formed to realize the sealing of the air flow tank 84 on both sides, and the corresponding sealing ring structure is assembled, and the collection tank 82 is sealed with the card part at this position. The interval is not directly connected with the inside of the drive cavity 11, but is connected with the collection tank 82 through the air flow tank 84, as shown in Figure 3 or Figure 5 .

[0047] The dust suction port 3 is arranged below the cover structure 5 and is an integral structure with the cover structure 5. One end of the suction pipe 81 is communicated with the dust suction port 3, and the other end is communicated with the backflow hole on the side of the collection tank 82. The fan 83 is installed on the other end of the drive motor 75. One end of the air flow tank 84 is opposite to the fan 83, and the other end is communicated with the collection tank 82. At least one dustproof net is installed at the port. The guide groove hole 85 is arranged on the side of the drive cavity 11, as shown in Figure 6 When actually used, the drive motor 75 rotates, the fan 83 extracts the air in the air flow tank 84, and then reduces the pressure in the collection tank 82. At this time, the airflow carrying dust passes through the dust suction port 3, the suction pipe 81, and reaches the collection tank 82. The filtered air passes through the guide groove hole 85 to balance the pressure inside and outside the drive cavity 11.

[0048] In this structure design, the air flow tank 84 includes a straight section 821 and a curved section 822 connected to the curved section 822. The end surface of the curved section 822 is outwardly bent to form a clamping ring end 823 for assembly in the inside of the drive cavity 11. The cross-sectional area of the curved section 822 gradually increases, and the maximum area end is close to the fan 83. The design here is that the power of the fan 83 is unchanged, the flow rate in the curved section 822 is smaller, and the flow rate in the straight section 821 is larger, which can quickly reduce the pressure in the collection tank 82, thereby realizing the rapid collection of dust.

[0049] The hand-held cavity 12 in the embodiment is internally provided with a power supply, which is electrically connected to the driving mechanism, and a mounting hole is formed in the side of the hand-held cavity 12 for elastically mounting the switch 6, and the switch 6 is pressed to start or stop the motor.

[0050] The above is only the preferred embodiment of the present application, and it should be pointed out that: for ordinary skilled in the art, without departing from the principles of the present application, can make a number of improvements and refinements, these improvements and refinements should also be considered as the protection scope of the present application.
