Description

Technical Field

[0001] The utility model relates to the technical field of railway maintenance, and particularly relates to a rail fastener grinding device. Background Art

[0002] As a fastening device part for buckling the rail and the sleeper, the rail fastener is directly related to the safety and stability of train operation.

[0029] Please refer to Figures 1 to 7, the rail fastener grinding device in the embodiment of the present utility model is slidably connected to the rail. The rail includes a first sub-rail 610 and a second sub-rail 620. The rail fastener grinding device includes a vehicle body 100, a plurality of frames 200 and a plurality of grinding mechanisms. A plurality of sliding members 130 are provided at the bottom of the vehicle body 100, and the sliding members 130 are slidably connected to the first sub-rail 610. An auxiliary rod 110 is connected to one side of the vehicle body 100, and an auxiliary wheel 120 is connected to the end of the auxiliary rod 110 facing away from the vehicle body 100. The auxiliary wheel 120 is slidably connected to the second sub-rail 620. A plurality of the frames 200 are connected to the side wall of the vehicle body 100, and the frames 200 are movably connected to the grinding mechanisms. The grinding mechanism includes a first rod body 310, a second rod body 320 and a plurality of third rod bodies 330. The frame 200 includes a first connecting plate 210 and a plurality of second connecting plates 220. One side of the first connecting plate 210 is connected to the side wall of the vehicle body 100, and a plurality of the second connecting plates 220 are connected to the side of the first connecting plate 210 facing away from the vehicle body 100. Through holes 221 are provided on the second connecting plates 220, and the through holes 221 penetrate through the second connecting plates 220. Connecting holes are provided at the ends of the first rod body 310, the second rod body 320 and the plurality of third rod bodies 330 facing the frame 200. The first rod body 310, the second rod body 320 and the plurality of third rod bodies 330 are movably connected to the frame 200 through connecting rods 230. The connecting rods 230 pass through the plurality of through holes 221 and the plurality of connecting holes. Torsion springs 240 are connected between the frame 200 and the first rod body 310, the second rod body 320 and the plurality of third rod bodies 330 respectively, so as to adjust the angle of the included angle formed between the first rod body 310, the second rod body 320 and the plurality of third rod bodies 330 and the side wall of the vehicle body 100 through the torsion springs 240. A plurality of the torsion springs 240 are all sleeved on the connecting rods 230. One end of the torsion spring 240 is connected to the second connecting plate 220, and the other end of the torsion spring 240 is connected to the first rod body 310, the second rod body 320 or the plurality of third rod bodies 330.Preferably, the sliding member 130 is a pulley, which is adapted to the first sub-rail 610. Two of the frames 200 and two of the grinding mechanisms are provided. The two grinding mechanisms are respectively located on both sides of the first sub-rail 610. Two of the third rods 330 are provided. The first rod 310 and the second rod 320 are respectively located on both sides of the two third rods 330. And the second rod 320 in the grinding mechanism is close to the first sub-rail 610. The second connecting plate 220 is perpendicular to the first connecting plate 210. The second connecting plates 220 are distributed on both sides of each rod. The torsion springs 240 are connected to the opposite side walls of each rod to enhance the stability of the connection between the frame 200 and the grinding mechanism. It can be understood that the auxiliary rod 110, the auxiliary wheel 120 and the sliding member 130 enable the vehicle body 100 to travel along the rail. The rail fastener grinding device can perform efficient grinding along the railway by driving the train. By using the torsion spring 240, not only a certain strength and durability are ensured, but also a certain degree of flexibility is provided in the connection between the grinding mechanism and the frame 200, enabling the torsion spring 240 to work freely within a preset angular range at one end. When the vehicle body 100 travels along the rail, the generated vibration and impact force can be alleviated, and at the same time, the connected components are protected from stress damage, improving the working efficiency and service life of the entire grinding system. Facing different railway lines and different specifications of rail fasteners 500, through the adjustment of the torsion spring 240, the installation positions of the first rod 310, the second rod 320 and the two third rods 330 can be adjusted to make the rail fastener grinding device adapt to the rail fastener 500, greatly increasing the flexibility and adaptability of the rail fastener grinding device.

[0030] One end of the first rod 310 and several of the third rods 330 facing away from the frame 200 are both connected to a driving assembly. The driving assembly corresponding to the first rod 310 is connected to a first grinding brush 410, and the driving assembly corresponding to the third rod 330 is connected to a second grinding brush 420. One end of the first grinding 410 brush facing away from the first rod 310 is movably connected to the second rod 320. Preferably, both the first grinding brush 410 and the second grinding brush 420 are wire brushes. The second grinding brush 420 is connected to the side of the third rod 330 facing away from the other third rod 330. The number of several of the second grinding brushes 420 is the same as the number of several of the third rods 330, both being 2. The width of the first grinding brush 410 is greater than that of the second grinding brush 420. The two second grinding brushes 420 are located on both sides of the grinding mechanism. The first grinding brush 410 is located at the central position of the grinding mechanism. Please refer to Figure 3, the shape of the rail fastener 500 is high in the middle and low on both sides. The first grinding brush 410 is used to grind the first sub-fastener 510 in the rail fastener 500. The first sub-fastener 510 is set at a higher position and is located at the central position of the rail fastener 500. The first sub-fastener 510 is a bolt. The first grinding brush 410 can grind the top surface of the bolt and the middle part of the rail fastener 500. The two second grinding brushes 420 are respectively used to grind the second sub-fastener 520. The setting position of the second sub-fastener 520 is lower than that of the first sub-fastener 510. The setting heights of the two second grinding brushes 420 are lower than that of the first grinding brush 410, and the second sub-fastener 520 is ground from both sides of the first sub-fastener 510. It can be understood that the first grinding brush 410 and the two second grinding brushes 420 grind the rail fastener 500 from different heights. The three wire brushes cover the entire surface of the fastener. The grinding mechanism is symmetric along both sides of the rail. The six wire brushes grind simultaneously, which is efficient and convenient. The first grinding brush 410 and the two second grinding brushes 420 are arranged in a staggered manner, effectively utilizing the grinding space. The grinding mechanism occupies a relatively small overall space and has accurate grinding at the same time.

[0031] The driving assembly includes a motor 312, a fixing plate 313, a first gear 314, a second gear 315 and a rotating shaft 316. Accommodation cavities 311 are provided at the ends of the first rod body 310 and several third rod bodies 330 facing away from the frame 200. The motor 312 is located in the accommodation cavity 311. The ends of the first rod body 310 and several third rod bodies 330 facing away from the frame 200 are both connected to the fixing plate 313. The output end of the motor 312 passes through the fixing plate 313 and is connected to the first gear 314. The second gear 315 is connected to the side wall of the fixing plate 313. The second gear 315 meshes with the first gear 314. The second gear 315 is connected to the rotating shaft 316. The rotating shaft 316 corresponding to the first rod body 310 is connected to the first grinding brush 410. One end of the rotating shaft 316 corresponding to the first rod body 310 facing away from the second gear 315 is movably connected to one end of the second rod body 320 facing away from the frame 200. The rotating shaft 316 corresponding to the third rod body 330 is connected to the second grinding brush 420. Preferably, both the first gear 314 and the second gear 315 are bevel gears, which is convenient for the power provided by the motor 312 to be vertically transmitted. The second rod body 320 increases the stability of the relatively wide first grinding brush 410. It can be understood that during the process of the rail fastener grinding device moving along the railway track, the motors 312 at six positions are activated to drive the wire brushes to rotate at high speed, so as to perform a comprehensive and efficient grinding operation on a large number of fasteners on the railway.
