Description

Technical Field

[0001] This utility model relates to the field of track cutting equipment technology, specifically a rail clamping device for a rail sawing machine. Background Technology

[0002] Rail saws (such as those commonly used by railway bureaus) are highly efficient and versatile railway maintenance equipment. Their high efficiency, high precision, ease of operation, and wide range of applications make them indispensable for railway maintenance. They are widely used on numerous railway lines, including high-speed railways, intercity railways, the Dabie Mountains railway, and the Nanchang-Jiujiang railway, playing a positive role in railway maintenance and construction. Primarily used for cutting railway tracks, they can cut tracks to any required length. In modern railway maintenance, rail saws have become indispensable equipment, characterized by speed, efficiency, and precision, greatly improving the efficiency of railway adjustment and maintenance.

[0003] The main principle of a rail saw is to cut railway tracks using a high-speed rotating saw blade. During this process, the size of the kerf and the rotation speed of the saw blade will have a certain impact on the cutting effect. Generally, rail saws use very high saw blade speeds, reaching several thousand revolutions per minute, resulting in smooth kerfs without cracks.

[0004] Therefore, some key points need to be noted during use. First, the length and position of the sawing track need to be clearly defined. Second, to avoid vibration affecting the cutting effect, sufficient machine stability needs to be maintained. Attention also needs to be paid to the selection and maintenance of the saw blade to ensure its efficiency and safety.

[0005] However, the rail clamping device of the existing rail sawing machine is a three-point clamping rail clamp. The three-point clamping rail clamp is balanced by the friction generated by the screw tip pressing against the rail. The locking of the three-point clamp tip will leave a pit on the side of the rail and cannot guarantee against the risk of derailment. It is necessary to add anti-derailment hook to reduce the risk of derailment. It cannot well meet the use requirements. Therefore, a rail clamping device for rail sawing machine is proposed to solve the above technical problems and overcome the above technical defects. Utility Model Content

[0006] To overcome the technical deficiencies in the prior art and effectively solve the technical problems in the background art, this utility model provides the following technical solution:

[0007] A rail clamping device for a rail saw includes two crossbeams, each symmetrically arranged. A vertical, inwardly inclined fixing rod is integrally formed on the rear side of the bottom of each crossbeam, and a connecting rod is provided between the two fixing rods. A vertical column is integrally formed on the front side of the bottom of each crossbeam, and an mounting rod is provided between the two columns. A threaded hole is formed in the middle of the front side of the mounting rod, and a threaded rod is threaded into the threaded hole. Adjustment holes are arranged laterally on the sides of the front ends of both crossbeams. An adjustment rod is detachably installed in one set of adjustment holes on each crossbeam. Movable locking rods are symmetrically arranged at the left and right ends of the outer side of the adjustment rod, and a connecting plate is provided between the two movable locking rods. The threaded rod extends to the rear end of the mounting rod and is rotatably connected to the middle of the front side of the connecting plate via a hinge.

[0008] As a preferred embodiment of this utility model, an auxiliary nut is threadedly connected to the outer side of the threaded rod at a position between the mounting rod and the connecting plate.

[0009] As a preferred technical solution of this utility model, the upper part of the side of the movable locking rod is provided with an installation hole for the adjusting rod to pass through and install. The outer sides of both ends of the adjusting rod are provided with external threads, and the external threads are threaded with fixing nuts for installing and disassembling the adjusting rod and the two movable locking rods.

[0010] As a preferred embodiment of this utility model, a rotating block is provided at the front end of the threaded rod in front of the mounting rod, and an auxiliary rotating rod perpendicular to the threaded rod is provided on the side of the rotating block.

[0011] As a preferred embodiment of this utility model, a reinforcing rod one is provided between the two movable levers, and a reinforcing rod two is provided between the two columns.

[0012] As a preferred embodiment of this utility model, the rear sides of the upper surfaces of the two crossbeams are respectively provided with a connecting part one and a connecting part two for connecting with a rail sawing machine.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The rail clamping device of this rail sawing machine, through two fixed clamping rods and two movable clamping rods, transforms the existing three-point clamping rail clamp into a four-jaw rail clamp. After clamping, the opening of the rail clamp is smaller than the size of the rail head, making the clamping more stable, preventing clamping marks and dents, and preventing derailment (specifically, by turning the threaded rod, the connecting plate and the two movable clamping rods are driven to rotate backward, causing the two movable clamping rods to tilt backward, thereby transforming the existing three-point clamping rail clamp into a four-jaw rail clamp. The four-jaw rail clamp distributes the entire thread force of the screw through two planes to clamp the corner of the rail, resulting in almost no clamping marks. Moreover, the bottom of the four-jaw rail clamp is smaller than the head of the rail on both sides, which can basically avoid the risk of derailment).

[0014] The adjustment rod can be adjusted according to different track widths through the cooperation of the adjustment hole and the adjustment rod (specifically, the adjustment rod can be disassembled and installed according to the needs of different track widths by connecting and disassembling the external thread and the fixing nut).

[0015] By using the auxiliary nut in conjunction with the mounting rod and threaded hole, the double nut can be tightened to prevent movement during cutting. It can also increase the thread length, thereby increasing rigidity. Furthermore, it can be used in emergency situations where the threaded rod needs to be tightened (allowing the auxiliary nut to replace the mounting rod and threaded hole), making cutting more stable and safer.

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.

[0023] Please see Figure 1-5This utility model provides a technical solution: a rail clamping device for a rail saw, comprising two horizontal beams 1, which are symmetrically arranged. Vertically inclined fixing rods 2 are integrally provided on the rear side of the bottom of each of the two horizontal beams 1. A connecting rod 4 is welded and fixed between the two fixing rods 2. Vertical columns 3 are integrally provided on the front side of the bottom of each of the two horizontal beams 1. An installation rod 5 is welded and fixed (or bolted and nut-threaded) between the two columns 3. A threaded hole 6 is provided in the middle of the front side of the installation rod 5, and a threaded connection is made within the threaded hole 6. The rod 7 and the two crossbeams 1 have horizontally arranged adjustment holes 8 on their front sides. An adjustment rod 9 is detachably installed in one set of adjustment holes 8 on each of the two crossbeams 1. During use, the adjustment rod 9, in conjunction with the adjustment holes 8, can be adjusted according to the width of different tracks 22. Movable locking rods 10 are symmetrically arranged at the left and right ends of the outer side of the adjustment rod 9. A connecting plate 12 is welded and fixed between the two movable locking rods 10. The threaded rod 7 extends to the rear end behind the mounting rod 5 and is rotatably connected to the middle of the front side of the connecting plate 12 via a hinge. During use, if... Figure 5 As shown, by turning the threaded rod 7, the connecting plate 12 and the two movable clamping rods 10 are driven to rotate backward, causing the two movable clamping rods 10 to tilt backward, thereby changing the existing three-point clamping rail clip into a four-jaw rail clip. After clamping, the opening of the rail clip is smaller than the size of the rail head, making the clamping more stable, preventing clamping marks and dents, and preventing detachment.

[0024] Furthermore, such as Figure 3 and 4 As shown, an auxiliary nut 15 is threadedly connected to the outer side of the threaded rod 7, located between the mounting rod 5 and the connecting plate 12. In use, the auxiliary nut 15 works in conjunction with the mounting rod 5 and the threaded hole 6 to prevent movement during cutting by tightening the double nuts, increase the thread length and thus increase rigidity, and allow the threaded rod 7 to continue to be used in emergency situations (allowing the auxiliary nut 15 to replace the function of the mounting rod 5 and the threaded hole 6).

[0025] Furthermore, such as Figure 4 As shown, the upper part of the side of the movable locking rod 10 is provided with a mounting hole 11 for the adjusting rod 9 to pass through and install. The outer sides of both ends of the adjusting rod 9 are provided with external threads 16. The external threads 16 are threaded with fixing nuts 17 for installing and removing the adjusting rod 9 and the two movable locking rods 10. In use, the threaded connection and removal of the external threads 16 and fixing nuts 17 facilitates the connection and limiting fixation of both ends of the adjusting rod 9 after it passes through the corresponding adjusting hole 8 and mounting hole 11, and also facilitates the removal of the adjusting rod 9.

[0026] Furthermore, such as Figure 3 and 4As shown, a rotating block 13 is welded and fixed to the front end of the threaded rod 7 in front of the mounting rod 5. An auxiliary rotating rod 14 perpendicular to the threaded rod 7 is provided on the side of the rotating block 13. In use, the threaded rod 7 can be easily rotated and adjusted by the rotating block 13 and the auxiliary rotating rod 14 without the need for third-party external tools.

[0027] Furthermore, such as Figure 4 As shown, reinforcing rods 18 are welded and fixed between the two movable locking rods 10, as follows: Figure 2 As shown, reinforcing rod 19 is welded and fixed between the two columns 3. During use, reinforcing rod 18 and reinforcing rod 19 play an auxiliary role in strengthening the support and fixing.

[0028] Furthermore, such as Figure 1 As shown, the rear sides of the upper surfaces of the two crossbeams 1 are respectively provided with a connecting part 1 20 and a connecting part 21 for connecting with the rail saw. In use, the device is connected to the rail saw through the connecting part 1 20 and the connecting part 21 to facilitate clamping and sawing of the rail 22. The connection and operation principle is a mature existing technology and will not be described in detail here.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
