Description

Technical Field

[0001] The invention relates to the technical field of rail bolt tightening and oiling, and in particular to an automatic rail bolt tightening and oiling device. Background Art

[0002] In railway transportation, rails are extremely important components that bear train loads and transmit train power. Rails and roadbeds need to be fixed and connected by bolts. If the bolts are loose or fall off, it will lead to serious consequences such as rail failure, breakage or locomotive derailment. Therefore, in order to ensure the safety and reliability of railway transportation operations, bolts generally need to be tightened and oiled regularly. After applying oil to the bolts, the friction of the bolts can be enhanced, so that they are more firmly fixed on the rails and the risk of bolt loosening or falling off is reduced;

[0003] At present, the most common tightening and oiling method is to carry an oil barrel manually, dip a brush into the oil and apply it to the bolt, and then tighten the bolt with a wrench. This rail bolt tightening and oiling method consumes a lot of manpower and is inefficient. Although some rail bolt oiling equipment runs between two tracks and then automatically sprays the oil to the top of the bolt through a nozzle, the efficiency of bolt oiling is improved, but the oil sprayed on the top of the bolt is not easy to spread evenly to different positions on the outside of the bolt, resulting in the nut on the bolt or some areas on the outside of the stud not being coated with oil, resulting in poor rail bolt oil coating effect, and most rail bolt oiling equipment cannot tighten the nut on the bolt during the oiling process, resulting in the need to re-tighten the nut on the bolt later;

[0004] In view of this, it is necessary to design an automatic tightening and oiling device for rail bolts, which can tighten the bolts while automatically oiling the bolts in all directions. Summary of the invention

[0005] In order to overcome the above-mentioned technical problems, the purpose of the present invention is to provide an automatic tightening and oiling device for rail bolts, wherein the cylinder drives the tightening ring on the support frame to adjust the position in the height direction, the screw rod rotates to make the transmission rod drive the tightening ring to adjust the position horizontally, so that the tightening ring arranged above the bolt moves down and is connected to the nut, and the motor drives the tightening ring to rotate to realize automatic tightening of the nut. In the process of moving the tightening ring toward the nut, the sliding rod moves up along the support cover, and after the notch on the outside of the sliding rod moves to the inside of the transmission tube, the oil inside the transmission tube will fall along the notch position and be added to the stud, so that the sliding rod synchronously releases the oil to the top of the stud during the process of tightening the nut, and the driving rod is driven to rotate at an eccentric position on the driving wheel disc by moving, so that the oiling ring can make circular motions of different diameters around the nut and the stud, so that the sponge block on the outside of the oiling ring can evenly apply the oil to the outside of the bolt, which is beneficial to improving the efficiency of bolt tightening and oil application.

[0009] Furthermore, a gear one is fixed by a knot on the outer side of the top of the transmission tube, a motor two is fixed on the top surface of one end of the transmission rod, and a gear four meshing with the gear one is fixed on the output end of the motor two.

[0010] Furthermore, a plurality of notches are provided at equal angles in a circular shape on the outer side of the bottom of the slide rod, and a connecting ring rotatably connected to the oiling ring is fixed on the bottom surface of the support cover.

[0011] Furthermore, a sliding groove slidably engaged with the connecting plate is provided on the outer side of the movable tube, a plurality of stirring paddles are sleeved and fixed at equal intervals on the outer side of the bottom of the movable tube, and a mesh is provided on the outer side of the bottom of the movable tube.

[0012] The invention further comprises: one end of the hose is plugged into the inner bottom of the movable tube, the other end of the tube is plugged into the space between the slide rod and the transmission tube, and an oil pump is fixed in series on the outer side of the hose.

[0013] Further, on the outer sides of both of the driving wheel discs, there are fixedly arranged meshing transmission toothed rings. The driving mechanism includes a C-shaped plate fixedly connected to the rectangular frame. On the outer side of the C-shaped plate, there is a motor three fixedly arranged. The output end of the motor three is fixedly provided with a gear two that meshes and drives with the toothed ring.

[0014] Further, inside the driving wheel disc, there is a motor one fixedly embedded for driving the lead screw to rotate. The bottom of the limiting block is slidably connected to the rectangular frame, and the top of the limiting block is slidably connected to the transmission rod.

[0015] Further, at the four corners of the support frame, there are fixedly arranged support legs. The bottom ends of the support legs are rotatably connected with rollers, and on one side of the support frame, there is a traction rod fixedly arranged.

[0016] Further, on both sides of the support frame, there are positioning rods slidably inserted. The bottom surface of the positioning rod is fixedly provided with a connecting block fixedly connected to the rectangular frame.

[0017] Advantages of the present invention:

[0018] 1. When the output end of the air cylinder shortens, the rectangular frame drives the transmission rod to move upward. The transmission rod drives the oiling fastener as a whole to move upward. The motor one drives the lead screw to rotate, and the moving column screwed to the lead screw drives the oiling fastener at the end of the transmission rod to move as a whole in the direction close to the top of the bolt, so that the tightening ring is arranged above the stud of the bolt. Then, when the output end of the air cylinder elongates, the rectangular frame moves downward. The rectangular frame drives the tightening ring to move downward through the transmission rod and sleevingly arrange it on the nut. The motor two drives the gear four to rotate, and the gear four drives the gear one on the transmission pipe to rotate. Further, the transmission pipe drives the tightening ring sleeved outside the nut to rotate through the support cover, so that the tightening ring screws the loose nut onto the stud, realizing automatic screwing of the nut.

[0019] During the process of the tightening ring moving towards the nut, the bottom end of the sliding rod inside the support cover abuts against the top surface of the stud, and as the tightening ring moves downward, the sliding rod gradually moves upward along the support cover. When the notch on the outer side of the sliding rod moves into the interior of the transmission pipe, the oil liquid conveyed through the hose inside the transmission pipe will fall along the notch position and be added to the top surface of the stud. Thus, during the process of screwing the nut, the sliding rod synchronously releases oil liquid towards the top end of the stud. By means of the motor two driving the gear four to rotate forward and backward, further, the gear one drives the transmission pipe to rotate forward and backward as well, so that the tightening ring at the bottom end of the transmission pipe can drive the nut to rotate forward and backward on the stud, realizing the movement of the nut on the stud, facilitating the oil liquid at the top end of the stud to fully penetrate into the thread grooves between the nut and the stud, and facilitating the oil liquid to fully impregnate the thread grooves between the stud and the nut.

[0020] 2. When the output end of the air cylinder elongates, the oiling ring is arranged outside the nut (refer to the specification Figure 1), the motor one drives the screw rod to rotate so that the moving column screwed with it moves toward the center of the driving wheel disc, and at this time, the transmission rod drives the oiling ring under the support tube to move synchronously toward the direction of the nut, and when the sponge sleeve fixed on the outer side of the oiling ring contacts the nut, the screw rod stops rotating, and the motor three drives the gear two to rotate so that the two driving wheels rotate, and the driving wheels rotate around the center of the driving wheel disc with the transmission rod through the eccentrically arranged moving column, and at this time, the transmission rod slides on the top of the limit block, and the bottom of the limit block slides on the rectangular frame, so that the sponge sleeve on the oiling ring can rotate around the nut with the stud as the axis, so that the oil dripped onto the outside of the nut can be evenly applied to On the outside of the nut, the cylinder output end moves up with the rectangular frame so that the transmission rod moves up with the oiling ring on the support tube, so that the sponge block on the outside of the oiling ring can move up to the outside of the thread on the stud that is not screwed with the nut, and then the motor 1 drives the screw rod to rotate again so that the transmission rod moves to the outside of the stud through the support tube with the oiling ring, and similarly the sponge sleeve contacts the external thread on the outside of the stud, and the motor 3 drives the gear 2 to rotate again so that the two driving wheels rotate, and similarly the oiling ring drives the sponge sleeve to rotate on the external thread on the outside of the stud, so that the oil dripping on the outside of the stud is evenly applied to the outside of the stud, thereby improving the bolt oil application efficiency and evenly applying the oil to the outside of the bolt;

[0021] 3. Gear three is meshed and rotated on the outer side of the driving wheel, and an oil barrel is fixed on the top surface of gear three. During the rotation of the driving wheel, the gear ring on the outer side of the driving wheel will drive gear three to rotate to rotate the oil barrel. A movable tube is inserted and arranged inside the oil barrel, and multiple stirring paddles are evenly fixed on the outer side of the movable tube. The stirring paddles can stir the oil during the rotation of the oil barrel to prevent the oil from settling. At the same time, the movable tube can slide up and down along the connecting plate, so that when the rectangular frame moves the oil barrel upward, the movable tube can move upward synchronously with multiple stirring paddles, so that the oil can be stirred synchronously during the process of tightening and oiling the bolts, preventing the oil from settling and affecting the lubrication and rust prevention effects of the oil.

The driving mechanism 600 includes a U-shaped plate 610 fixedly connected to the rectangular frame 200. A motor three 620 is fixedly provided on the outer side of the U-shaped plate 610. The output end of the motor three 620 is fixedly provided with a gear two 630 meshing with the gear ring, so that the two driving wheel discs 300 can rotate.

[0036] A motor one 320 for driving the screw rod 310 to rotate is fixedly embedded in the driving wheel disc 300. The bottom of the limiting block 410 is slidably connected to the rectangular frame 200, and the top of the limiting block 410 is slidably connected to the transmission rod 400. The limiting block 410 enables the end of the transmission rod 400 to move along a circular track; Support legs are fixedly provided at the four corners of the support frame 100. The bottom ends of the support legs are rotatably connected with rollers 120. A towing rod 130 is fixedly provided on one side of the support frame 100. Positioning rods 140 are slidably inserted on both sides of the support frame 100. The bottom surface of the positioning rod 140 is fixedly provided with a connecting block fixedly connected to the rectangular frame 200.

[0037] Working principle: When in use, the two rollers 120 at both ends of the support frame 100 are rolled against the corresponding rails, the spare oil is added into the oil barrel 710, and two hoses 822 are plugged into the movable tube 820 inside the oil barrel 710. One end of the hose 822 can suck the oil inside the oil barrel 710 through the mesh 821 at the bottom of the movable tube 820, and then the oil is injected from the other end of the hose into the space between the transmission tube 560 and the sliding rod 550 with the help of an oil pump. When the bolts are tightened and oiled, the output end of the cylinder 110 is shortened to make the rectangular frame 200 move up with the transmission rod 400, and the transmission rod 400 moves up with the oiled fastener 500 as a whole, and the motor 320 drives the oiled fastener 500 to move up. The screw rod 310 rotates to make the movable column 311 screwed with the screw rod 310 move the oiled fastener 500 at the end of the transmission rod 400 toward the top of the bolt as a whole, so that the tightening ring 530 is arranged above the bolt stud. Then the output end of the cylinder 110 extends to make the rectangular frame 200 move downward. The rectangular frame 200 moves the tightening ring 530 downward through the transmission rod 400 and is sleeved on the nut. The motor 2 420 rotates the gear 4 so that the gear 4 rotates the gear 1 561 on the transmission tube 560. The transmission tube 560 rotates the tightening ring 530 sleeved on the outside of the nut through the support cover 520, so that the tightening ring 530 tightens the loose nut onto the stud, thereby realizing automatic tightening of the nut.

[0038] When the tightening ring 530 moves toward the nut in the vertical direction, the bottom end of the slide bar 550 inside the support cover 520 abuts against the top surface of the stud, and as the tightening ring 530 moves downward, the slide bar 550 gradually moves upward along the support cover 520. When the notch 552 on the outside of the slide bar 550 moves into the inside of the transmission tube 560, the oil transported from the transmission tube 560 through the hose 822 will fall along the notch 552 and be added to the top surface of the stud, and then poured from the top of the stud to the nut. When the oil on the outside of the bolt needs to be evenly applied, the output end of the cylinder 110 is extended so that the oiling ring 540 is arranged on the outside of the nut (refer to the instruction manual). Figure 1), the motor 1 320 drives the screw rod 310 to rotate so that the movable column 311 screwed therewith moves toward the center of the driving wheel 300, and the transmission rod 400 drives the oiling ring 540 under the support tube 510 to move synchronously toward the direction of the nut. When the sponge sleeve fixed on the outer side of the oiling ring 540 contacts the nut, the screw rod 310 stops rotating, and the motor 3 620 drives the gear 2 630 to rotate so that the two driving wheels 300 rotate. The driving wheel 300 rotates around the center of the driving wheel 300 through the eccentrically arranged movable column 311 with the transmission rod 400, and the transmission rod 400 slides on the top of the limit block 410, and the bottom of the limit block 410 slides on the rectangular frame 200, so that the sponge sleeve on the oiling ring 540 can rotate around the nut with the stud as the axis, and the oil dripped onto the outer side of the nut is evenly applied to the nut. The outer side of the cap, the output end of the cylinder 110 moves up with the rectangular frame 200 so that the transmission rod 400 moves up with the oiling ring 540 on the support tube 510, so that the sponge block on the outer side of the oiling ring 540 can move up to the outside of the thread of the stud that is not screwed with the nut, and then the motor 1 320 drives the screw rod 310 to rotate again so that the transmission rod 400 moves to the outside of the stud through the support tube 510 with the oiling ring 540, and similarly the sponge sleeve contacts the external thread on the outer side of the stud, and the motor 3 620 drives the gear 2 630 to rotate again so that the two driving wheels 300 rotate, and similarly the oiling ring 540 rotates with the sponge sleeve on the external thread on the outer side of the stud, so that the oil dripping to the outside of the stud is evenly coated on the outside of the stud, and the tightening and oiling device can move to different positions along the rail, so as to facilitate the tightening and oiling of bolts at different positions on the rail.
