Description

Technical Field

[0001] This utility model relates to the field of rail cutting technology, specifically a rail cutting device that maintains stable cutting. Background Technology

[0002] Steel rails are the main component of railway tracks. Their function is to guide the wheels of locomotives and rolling stock, bear the enormous pressure of the wheels, and transmit it to the sleepers. Over time, steel rails require maintenance and replacement, necessitating the use of cutting equipment to cut them.

[0003] The existing rails are generally cut using a rail cutting machine. In practice, the operator lifts the cutting equipment, places it on the rail, and applies pressure manually to the equipment to cut the rail.

[0004] However, when workers need to cut rails, they hold the cutting equipment with both hands and rely on manual pressure to cut. Because the rail material is relatively hard, cutting takes time, and holding it for a long time will cause the cutting to shake, resulting in the cutting groove tilting, affecting the cutting quality and subsequent removal of the cutting saw blade. For example, the cutting may be uneven, making it impossible to complete the subsequent connection. Furthermore, when workers manually cut the rails with the cutting equipment, the cutting saw blade is prone to slipping when it comes into contact with the rail due to the rotation of the cutting saw blade.

[0005] In addition, the cutting equipment will spew a lot of sparks when cutting rails. If the exposed area of ​​the cutting saw blade is large, it will pose a safety hazard to the operator during the cutting process.

[0006] Based on this, the present invention provides a rail cutting device that maintains stable cutting to solve the above problems. Utility Model Content

[0025] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figures 1 to 5The detailed description of the embodiments will make this clear. All references to the following embodiments are made with reference to the accompanying drawings.

[0026] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings.

[0027] As one embodiment, this utility model is a rail cutting device that maintains stable cutting, used to provide stability of the cutting device during cutting. It includes an existing engine 1, which is a diesel engine or a new energy engine. The engine 1 is fixedly connected to a frame 4. The output end of the engine 1 is connected to the frame 4. A transmission system is installed inside the frame 4 to drive the subsequent spindle 6. A saw blade guard 5 is fixed on one side of the frame 4. The saw blade guard 5 has an arc-shaped cavity inside. The spindle 6 passes through the saw blade guard 5 and is placed inside the saw blade guard 5. A cutting saw blade 7 is fixedly sleeved on the spindle 6.

[0028] A bearing seat 8 is fixedly connected to the outside of the frame 4. A first rotating frame 9 is rotatably connected to the bearing seat 8. A second rotating frame 10 is rotatably connected to the bottom of the first rotating frame 9. Support frames 19 are connected to both sides of the bottom of the second rotating frame 10. Clamping plates 21 that can be locked onto the rail are rotatably installed at both ends between the two support frames 19. Limit blocks 23 are fixed at the lower end of the clamping plates 21 for locking the rail.

[0029] In this embodiment, the rail is an I-shaped rail with grooves on both sides. During cutting, after opening the two clamping plates 21, the rail is placed between the two clamping plates 21, with the upper end of the rail abutting against the support frame 19. The limiting block 23 is placed in the grooves on both sides of the rail. By rotating the two clamping plates 21, the two sides of the rail are locked, thus fixing the rail. Rotating the first rotating frame 9 and the second rotating frame 10 can adjust the position of the cutting saw blade 7 during cutting, while ensuring the positive orientation of the cutting saw blade 7 during cutting, ensuring that the cutting saw blade 7 does not tilt during cutting, and ensuring that the cutting saw blade 7 can be taken out of the cutting groove in a positive direction without getting stuck.

[0030] As an example, a through storage hole 11 is provided on the second rotating frame 10. A vertical screw 12 is fixed at the top of the storage hole 11. A threaded cylinder 14 is threaded onto the screw 12. Vertical sliding frames 13 are fixed on both sides of the threaded cylinder 14. A fixed seat 15 is fixed at the lower end of the two sliding frames 13 and placed at the lower end of the screw 12. A pin is fixed on the outer periphery of the fixed seat 15 for easy manual rotation. A base 151 is rotatably connected to the lower end of the fixed seat 15. Limiting grooves 16 are provided on both sides of the storage hole 11. The limiting grooves 16 are placed on the second rotating frame 10. A sliding rod 17 is fixed on the base 151. The two ends of the sliding rod 17 are slidably placed in the limiting grooves 16 respectively.

[0031] Push rods 18 are rotatably connected to both sides of the bottom of the base 151. First rotating grooves 20 are provided on both sides of the support frame 19. Two clamping plates 21 are rotatably installed in the two first rotating grooves 20 on both sides. A second rotating groove 22 is provided on the top of the clamping plate 21. The other ends of the two push rods 18 are rotatably installed in the second rotating groove 22.

[0032] In this embodiment, the clamping plate 21 is rotated by turning the pin to drive the fixed seat 15 to rotate. The fixed seat 15 drives the sliding frame 13 to rotate. The sliding frame 13 drives the threaded cylinder 14 to move downward on the screw 12. When the fixed seat 15 moves downward, it pushes the base 151 to move downward. The slide rod 17 slides downward in the limiting groove 16. The two push rods 18 unfold outward. The push rods 18 push the clamping plate 21 to rotate, thereby causing the lower limiting block 23 to clamp inward, thus completing the fixation of the rail.

[0033] As an example, a baffle 27 is slidably provided at the bottom of the saw blade guard 5. Specifically, a limiting frame 24 is fixed at the bottom of the saw blade guard 5, and a T-shaped slider 25 is slidably connected inside the limiting frame 24. A first groove 26 is provided at the bottom of the limiting frame 24, and the bottom of the slider 25 passes through the first groove 26 and is connected to the baffle 27. The baffle 27 slides at the lower end of the limiting frame 24.

[0034] A second slide groove 28 is provided on one side of the limiting frame 24, and a push plate 29 is connected to one side of the slider 25. The push plate 29 passes through the second slide groove 28 and is placed outside the limiting frame 24.

[0035] In this embodiment, during cutting, in order to avoid a large number of sparks splashing onto the operator, the push plate 29 is pushed to slide in the second slide groove 28, and the slider 25 drives the baffle 27 to slide at the lower end of the limiting frame 24, so that the push plate 29 can block part of the cutting saw blade 7.

[0036] It should be noted that the baffle 27 will not affect the normal cutting of the rail by the cutting saw blade 7.

[0037] As an example, a handle 2 is fixed on the side of the engine 1 away from the frame 4, and a bracket 3 is fixed on the engine 1. The bracket 3 is located above the engine 1, and the cutting saw blade 7 is rotated and placed inside the saw blade guard 5.

[0038] When cutting, the handle 2 and the bracket 3 make it easy to hold the cutting equipment and facilitate the cutting of the rail.

[0039] The overall principle of this utility model is as follows: During use, the cutting saw blade 7 is aligned with the cutting position on the rail. After alignment, the support frame 19 is placed on top of the rail. Two clamping plates 21 on the support frame 19 are located on either side of the rail. The operator can rotate the sliding frame 13, causing it to rotate within the receiving hole 11. As the sliding frame 13 rotates, it drives the threaded cylinder 14 to rotate and descend on the screw 12, pushing the sliding frame 13 down within the receiving hole 11 and pushing the fixed seat 15 down. The two push rods 18 descend synchronously within the receiving hole 11, causing one end of each push rod 18 to descend synchronously. Through the cooperation of the two push rods 18, the two clamping plates 21 are pushed to rotate on the support frame 19. When the two clamping plates 21 rotate synchronously, their bottoms move closer to each other, thereby clamping the rail. During the clamping operation, the limiting blocks 23 on the two clamping plates 21 are embedded in both sides of the rail, making the clamping more stable and preventing the cutting equipment from shaking when cutting the rail.

[0040] After being secured by two clamping plates 21, the operator can move the cutting equipment using handle 2 and bracket 3. At this time, the cutting equipment will only move in parallel due to the support and limitation of the first rotating frame 9 and the second rotating frame 10, so that the cutting saw blade 7 on the cutting equipment is close to the rail. The engine 1 works and drives the main shaft 6 to rotate inside the saw blade guard 5 through the transmission system in the frame 4 to cut the rail.

[0041] During cutting, the operator can push the cutting equipment to make the first rotating frame 9 rotate on the bearing seat 8, and the second rotating frame 10 rotates on the first rotating frame 9 to cooperate, so that the cutting equipment can complete the cutting operation of the rail and keep the cutting trajectory perpendicular to the operation, making the cutting more convenient. After cutting, the operator can easily remove the cutting saw blade 7 from the cut groove.

[0042] During cutting, depending on the cutting angle, the operator can push the push plate 29 to move within the second slide groove 28, thereby causing the slider 25 to slide within the limit frame 24. Through the cooperation of the first slide groove 26, the arc-shaped baffle 27 is driven to rotate along the center of the saw blade guard 5, which helps to shield the sparks generated during rail cutting and protect the operator.

[0043] After cutting, the operator rotates the sliding frame 13 in the opposite direction, causing the threaded cylinder 14 on the sliding frame 13 to rise above the screw 12, pulling the fixed seat 15 up within the receiving hole 11. The push rods 18 on both sides of the fixed seat 15 pull the two clamping plates 21, causing the tops of the two clamping plates 21 to move closer together, thus making the two clamping plates 21 rotate synchronously on the support frame 19. At this time, the bottoms of the two clamping plates 21 move away from each other, causing the two limit blocks 23 to disengage from the rail, and the support frame 19 to be removed from the rail for subsequent operation.

[0044] The present invention has the following technical effects.

[0045] 1. This utility model rotates the fixed base to drive the sliding frame and the threaded cylinder to rotate on the screw, thereby causing the base to drive the push rod to rotate, the push rod to drive the clamping plate to rotate, and thus causing the limit block to be locked into the groove of the steel rail, locking the steel rail, so that the cutting saw blade can maintain stability when the handheld cutting device is cutting, and at the same time, it can provide support for the handheld cutting device.

[0046] 2. This utility model uses a push plate to drive a slider to slide in the second groove, which in turn drives a baffle to slide outside the saw blade guard, preventing a large number of sparks from splashing onto the operator during cutting and improving safety during cutting.
