Description

Technical Field

[0001] This utility model relates to the field of rail welding technology, and more specifically, to a high-efficiency rail welding auxiliary device. Background Technology

[0002] The weight of a single gas pressure rail welding machine ranges from 500-800 kg, making it quite heavy. Traditional gas pressure rail welding equipment requires at least four people to lift, walk, and transport it over short distances. For long distances, it must be manually lifted onto a rail flatbed truck for transport. When using gas pressure welding on existing operational lines, the effective working time during maintenance windows is short, typically only three hours. This necessitates multiple personnel for joint lifting and transport, resulting in increased manpower and time consumption, significantly impacting the effective welding time during maintenance windows and affecting the following day's operations. When using gas pressure welding on newly constructed lines, which are often long, the equipment needs to be transported every 25 meters using a rail flatbed truck.

[0003] The existing work methods result in workers frequently engaging in heavy physical labor, which affects their health; moreover, labor costs are high, work efficiency is low, and construction progress and the next day's operation are affected.

[0004] A search revealed a Chinese patent with publication number CN218799804U that discloses an auxiliary sliding and pushing device for a rail pneumatic welding equipment. This utility model eliminates the need for multiple people to lift and transport the equipment; one person can push the rail pneumatic welding equipment to slide along the rail direction, reducing manpower input, saving construction costs, improving work efficiency, accelerating construction progress, and ensuring safe operation the following day.

[0005] However, in actual use, when the above-mentioned auxiliary sliding pushing device is used to move and weld on the rail, the staff needs to level the two sections of rail again before the welding can continue. This process is relatively cumbersome and will directly affect the efficiency of rail welding. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a high-efficiency rail welding auxiliary device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A high-efficiency rail welding auxiliary device includes a base frame with two rails at its bottom. A placement box and mounting platform are fixedly connected to the top of the base frame. An auxiliary leveling mechanism is provided on the outer side of the base frame. The auxiliary leveling mechanism includes two connecting frames. Two cylinders are fixedly connected to the inner side of each connecting frame. A pad is fixedly connected to the bottom end of each cylinder. Multiple load-bearing rods are slidably connected to the inner side of each load-bearing rod. A cylinder is fixedly connected to the inner side of each load-bearing rod. A base box is fixedly connected to the bottom end of each cylinder. Two guide rods are fixedly connected to the lower surface of the base box. The outer sides of the guide rods are slidably connected to the inner sides of the load-bearing rods. A cylinder is fixedly connected to one side of the base box. A support plate is fixedly connected to one end of the cylinder. The outer side of the support plate is slidably connected to the inner side of the base box. Three guide wheels are rotatably connected to the upper surface of the support plate. An auxiliary drive mechanism is provided at the bottom of the base frame.

[0008] By adopting the above technical solution: the base frame is supported and limited by cylinder one and pad, and then the retractable load-bearing rods on both sides, cylinder two, base box and support plate are combined to lift and press the two ends of the steel rails to be welded upward and downward, so that the two ends of the steel rails to be welded can be kept straight for welding work.

[0009] As a further description of the above technical solution: the auxiliary drive mechanism includes two rotating rollers, the outer side of which is rotatably connected to the lower surface of the base frame, both ends of which are fixedly connected to baffles, and one side of each baffle is fixedly connected to a rotating wheel, the outer side of which is rotatably connected to the upper surface of the rail, one of which is fixedly connected to a bevel gear two, and a servo motor is fixedly connected to the lower surface of the base frame, the output end of which is fixedly connected to a bevel gear one, one side of which meshes with one side of the bevel gear two.

[0010] By adopting the above technical solution, the meshing transmission of a servo motor and a pair of bevel gears allows one of the rollers to drive the baffles and wheels on both sides to roll the rail, and in combination with the other roller, baffles and wheels to provide rolling support for the base frame, enabling the base frame to move smoothly and increasing the moving speed of the base frame on the rail surface.

[0011] The technical effects and advantages of this utility model are as follows: 1. By setting up an auxiliary leveling mechanism, compared with the existing technology, the vertical position of the rail can be precisely controlled by using two bottom boxes and a support plate to apply upward and downward forces to the rail. This enables rapid and accurate leveling of both ends of the rail, shortens the preparation time before welding, and improves the efficiency of rail welding. 2. By setting up an auxiliary drive mechanism, compared with the existing technology, a servo motor, bevel gear one, and bevel gear two are used to drive one of the rotating rollers, so as to promote the base frame to obtain a certain driving force, and the baffle plate is used to block and limit the rail, so as to maintain the stability of the base frame moving in the rail.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] The embodiments disclosed in this application are as follows: Figure 1-6The illustrated high-efficiency rail welding auxiliary device includes a base frame 1, with two rails 2 mounted at the bottom of the base frame 1. A placement box 3 and a mounting platform 4 are fixedly connected to the top of the base frame 1. An auxiliary leveling mechanism is provided on the outside of the base frame 1. The auxiliary leveling mechanism includes two connecting frames 5. Two cylinders 6 are fixedly connected to the inner side of the connecting frames 5. A pad 7 is fixedly connected to the bottom end of the cylinders 6. Multiple load-bearing rods 8 are slidably connected to the inner side of the base frame 1. Cylinders 9 are fixedly connected to the inner side of the load-bearing rods 8. A base box 10 is fixedly connected to the bottom end of the cylinders 9. Two guide rods 11 are fixedly connected to the lower surface of the base box 10. The outer side of the guide rods 11 is slidably connected to the inner side of the load-bearing rods 8. A cylinder 12 is fixedly connected to one side of the base box 10. One end of cylinder 12 is fixedly connected to a support plate 13. The outer side of the support plate 13 is slidably connected to the inner side of the base box 10. Three guide wheels 14 are rotatably connected to the upper surface of the support plate 13. An auxiliary drive mechanism is set at the bottom of the base frame 1. The tools required for welding are placed in the placement box 3. The support plate 13 is supported by multiple cylinders 6 and pads 7 after being moved to the appropriate position. The load-bearing rod 8, which can be pulled, is used in conjunction with cylinder 9 to raise and lower the base box 10 and cylinder 12 to push the support plate 13 laterally. This allows the support plate 13 and multiple guide wheels 14 to press down and push up the upper and lower sides of the two end rails 2, keeping the two end rails 2 straight and facilitating welding.

[0021] Reference Figure 3 and Figure 6 As shown, the auxiliary drive mechanism includes two rotating rollers 18. The outer sides of the rotating rollers 18 are rotatably connected to the lower surface of the base frame 1. Both ends of the rotating rollers 18 are fixedly connected to baffles 19. A rotating wheel 20 is fixedly connected to one side of the baffles 19. The outer side of the rotating wheel 20 is rotatably connected to the upper surface of the rail 2. A bevel gear 17 is fixedly connected to the outer side of one of the rotating rollers 18. A servo motor 15 is fixedly connected to the lower surface of the base frame 1. A bevel gear 16 is fixedly connected to the output end of the servo motor 15. One side of the bevel gear 16 meshes with one side of the bevel gear 17. The baffles 19 and the rotating wheel 20 on the outer sides of the two rotating rollers 18 rotate and move the top of the rail 2. Combined with the servo motor 15 and the bevel gear 16 meshing with the bevel gear 17, the base frame 1 receives driving force to facilitate movement.

[0022] The working principle of this utility model is as follows: When welding the rails 2, multiple rotating wheels 20 at the bottom of the base frame 1 are placed above the two rails 2. The gas pressure welding equipment is installed above the mounting platform 4, and the remaining welding parts are placed inside the placement box 3. Then, the servo motor 15 is started to drive the bevel gear 16 to mesh with the bevel gear 17, causing the bevel gear 17 to drive one of the rotating rollers 18 and the baffles 19 and rotating wheels 20 on both sides to rotate. Combined with the rotating roller 18, baffle 19 and rotating wheel 20 on the other side, the rails 2 are assisted to roll, allowing the base frame 1 to move above the rails 2. The multiple baffles 19 guide the two rotating wheels 20 to maintain the stability of the base frame 1's movement. Then, when moving to the position between the rails 2 where welding is required, multiple cylinders 6 are first started to push the pad 7 to the ground. Extend the base frame 1 to raise it above the two rails 2 and maintain its stability. Pull out the two load-bearing rods 8 on the side corresponding to the welded rails 2 from the inside of the base frame 1 so that the bottom boxes 10 at the bottom of the two load-bearing rods 8 can be moved to the outside of the rails 2. Then, according to the height difference between the front and rear ends of the rails 2, activate the two cylinders 2 9 to push the bottom boxes 10 closer and move them to the top of the high rail 2 and the bottom of the low rail 2 respectively. Then, activate the two cylinders 3 12 to push the support plate 13 to the top and bottom of the two rails 2. With the help of the three guide wheels 14, the support plate 13 rolls and enters the bottom of the low rail 2. Then, the two cylinders 2 9 drive the cylinders 3 12 and the support plate 13 to press down and push up the two rails 2 to keep the two rails 2 straight. Then, the workers use pneumatic welding equipment to weld the leveled two rails 2.
