Description

Technical Field

[0001] The invention relates to the technical field of railway maintenance, and in particular to a rust removal and oiling robot capable of automatically identifying railway fastener bolts. Background Art

[0002] Fasteners are the main components for maintaining track gauge, reducing noise, shock absorption and insulation in the railway track system. Failure of fasteners will affect the stability of the track system, and in serious cases will endanger the safety of train operation. Railway fastener bolt maintenance is one of the important means to ensure the safe, reliable and stable operation of the railway track system. At present, the bolt rust removal and oiling processes in the maintenance process of domestic railway rail clamps are mainly completed manually, which has the problems of complex maintenance process, high labor intensity and low efficiency. At the same time, the existing maintenance equipment has a low degree of automation and single function. When removing rust from the bolts, the nuts are generally completely unscrewed, then the bolts are rust-removed and oiled, and then the nuts are re-tightened. However, after the bolts are separated from the nuts, the bolts lose their limit and are easy to shake, resulting in the need to repeatedly adjust the nuts and bolts to align when re-tightening, resulting in average work efficiency. Summary of the invention

[0003] In order to overcome the above-mentioned technical problems, the purpose of the present invention is to provide a rust removal and oiling robot that can automatically identify railway fastener bolts. Through the setting of the working components, the brush head removes rust from the top of the bolt when the nut is at the bottom position, and removes rust from the bottom of the bolt when the nut is at the top of the bolt, thereby realizing rust removal of the bolt thread groove. When the nut is loosened to the top of the bolt, the extrusion sleeve is located on the inner side of the nut and contacts the nut, thereby oiling the inner wall of the nut, and the output end of the drive motor rotates in the opposite direction, thereby twisting the nut downward. The twisting of the nut coats the bolt with oil, and then the nut is twisted back and forth several times to complete the rust removal and oiling of the bolt, thereby realizing rust removal and oiling of the bolt thread groove without completely unscrewing the nut, which is convenient for re-tightening the nut, thereby increasing the rust removal and oiling effect of the fastener bolt.

Identification probes are fixedly installed at both ends of one side of the mounting plate. After the bottom end of the working assembly is aligned with the bolt, the hexagonal sleeve is sleeved with the nut, and the ring frame second loosens the nut upward, so that the brush head and the nut rotate upward synchronously, thereby cleaning and derusting the wire groove above the nut, that is, the top end of the bolt, through the brush head. As the nut is loosened, the brush head moves to the bottom of the nut, and as the nut and the hexagonal sleeve rotate upward, the brush head continues to rotate upward with the nut, thereby cleaning the wire groove below the nut, so that when the nut is at the bottom end position, the brush head derusts the top end of the bolt, and when the nut is at the top end of the bolt, the bottom end of the bolt is derusted, thereby realizing derusting of the wire groove of the bolt.

[0010] Furthermore, the limiting module includes an insert rod 2, which is slidably plugged into a ring frame 2, the bottom end of the insert rod 2 is fixedly connected to a limiting ring, the top end of the insert rod 2 is fixedly connected to a rotating seat, the rotating seat is rotatably connected to the top end of the curved arm, the top end of the outer wall of the insert rod 2 is slidably sleeved with an extrusion spring 2, and the bottom end of the limiting module is provided with a downward pressing component. When the ring frame 2 moves upward, the insert rod 2 is driven to move upward synchronously by the extrusion spring 2, thereby driving the curved arm and the ring frame 2 to move upward synchronously.

[0018] 3.

[0035] Working principle: When in use, the device is placed on the track, the driving module 110 drives the track wheel 120 to drive the device to move on the track, the identification probe 160 identifies and locates the fasteners on both sides of one side of the track, and after the bottom end of the working component 200 is aligned with the bolt, the driving module 110 controls the device to stop, the electric push rod 151 drives the fixing plate 152 to move downward, the fixing plate 152 drives the two main shaft rods 210 to move downward through the screw rod 155 and the fixing plate 2 154, until the bottom end of the oil pipe 290 moves to the top of the bolt, and the hexagonal sleeve 260 and The nut is sleeved, and the driving motor 140 drives the two rotating sleeves 220 to rotate through the belt, thereby driving the main shaft 210 to rotate, and the main shaft 210 drives the ring frame 1 230, the ring frame 240 and the hexagonal sleeve 260 to rotate. When the hexagonal sleeve 260 rotates, the nut is screwed, so that the nut rotates and moves upward, thereby driving the ring frame 240 to move upward. When the ring frame 240 moves upward, the elastic force of the second squeezing spring 274 pushes the curved arm 250 and the second plug rod 271 to move upward synchronously, so that the brush head 253 and the nut rotate upward synchronously, so that the brush head 253 can push the nut upward. The thread groove on the upper side of the nut, i.e., the top of the bolt, is cleaned and rusted until the rotating seat 272 contacts the inner bottom surface of the ring frame 1 230, and the ring frame 240 continues to move upward, so that the seat rod 242 moves upward relative to the crank arm 250. When the seat rod 242 moves to the position of the inner concave portion 252, the bottom end of the crank arm 250 is squeezed to deflect outward, and at the same time, the oiling head 292 squeezes the two squeezing plates 282, so that the angle between the two squeezing plates 282 increases, and the distance between the two squeezing plates 1 281 increases, thereby driving the insertion rod 271 to move downward relative to the ring frame 1 230. , so that the top of the second plug rod 271 is separated from the ring frame 1 230, and the seat rod 242 moves to the top of the inner recess 252, so that the brush head 253 at the bottom end of the crank arm 250 contacts the bolt again and moves to the bottom of the nut. As the nut and the hexagonal sleeve 260 rotate and move upward, the brush head 253 continues to rotate and move upward synchronously with the nut, thereby cleaning the wire groove below the nut, so that when the nut is at the bottom position, the brush head 253 removes rust from the top of the bolt, and when the nut is at the top of the bolt, the brush head 253 removes rust from the bottom end of the bolt, thereby achieving rust removal of the wire groove of the bolt;

[0036] When the nut is loosened to the top of the bolt, the extrusion sleeve 291 is located inside the nut and contacts the nut, so that the inner wall of the nut is oiled, and the output end of the driving motor 140 rotates in the opposite direction, so that the nut is screwed downward, and the screwing of the nut applies oil to the bolt. After the nut is screwed back and forth several times, the rust removal and oiling of the bolt are completed;

[0037] By setting the lifting module 150, the screw rod 155 is rotated to adjust the distance between the fixing plate 2 154 and the fixing plate 1 152, thereby adjusting the initial height of the ring frame 1 230, so as to facilitate adjustment and correction according to the height of the bolt, and facilitate the limit ring 273 to be close to the top of the bolt after the main shaft rod 210 is lowered, so as to facilitate manual correction.
