Description

Technical Field

[0001] The utility model relates to the technical field of rail clamps, in particular to a rail clamp with good safety. Background Art

[0002] A rail clamp is a tool or mechanical device used to clamp rails. In the railway industry, rail clamps are often used to fix rails to prevent them from shifting or deforming, ensuring the safe operation of trains. Rail clamps are usually made up of various metal components and can clamp rails through mechanical or hydraulic force to ensure the stability and safety of the rails. They play a vital role in railway maintenance and construction and are one of the indispensable equipment in the railway system.

[0003] After long-term use, the bolts and nuts of the existing rail clamps are prone to loosening under the action of vibration and dynamic loads, resulting in unstable clamping force. Bolts are also prone to loosening under repeated dynamic loads, requiring frequent maintenance and retightening. However, in actual operation, due to time and manpower constraints, this may not be carried out in a timely manner, resulting in the loosening of the rail clamp and subsequent failure. If the elastic element increases the clamping force, it will lose elasticity after long-term use, resulting in a decrease in clamping force. The hydraulic clamping method provides greater clamping force and stability, but the hydraulic system requires regular maintenance. Any oil leakage, pipeline aging, etc. will directly lead to system failure and cause the rail clamp to disengage. Therefore, when conventional rail clamps are used, clamping is achieved only through a single clamping structure. After long-term use, the stability is difficult to meet the requirements, which is likely to cause safety hazards.

[0036] In the process of clamping the rail, the device is not only convenient for clamping operation, but also can play the role of positioning after clamping, thereby realizing double positioning, avoiding the occurrence of unclamping, and having higher safety and stability.

[0037] The lower ends of the No. 1 clamping plate 2 and the No. 2 clamping plate 3 are fixedly provided with a clamp head 7, which is used to clamp the track. The other end of the threaded rod 12 is fixedly provided with a hand rod 9, and the threaded rod 12 is conveniently rotated by the hand rod 9.

The stainless steel material has a hard texture and strong corrosion resistance, and is more durable and safe to use.

[0039] The advantages of the utility model are dual positioning and fixing, specifically:

[0040] Mechanical clamping is the first step to achieve double positioning, and the preliminary fixation of the track is achieved through the threaded rod 12, the hand rod 9 and the clamping plate assembly.

[0041] Threaded rod 12 and hand lever 9:

[0042] Working principle: the hand lever 9 drives the threaded rod 12 by rotation, and the threaded rod 12 rotates to drive the first clamping plate 2 to move closer to the second clamping plate 3, thereby clamping the track.

[0043] Advantages: Easy to operate, flexible adjustment of clamping force to ensure close contact between the rail and the clamping plate.

[0044] Chuck 7:

[0045] Function: The lower ends of the No. 1 clamping plate 2 and the No. 2 clamping plate 3 are both provided with clamping heads 7, which directly contact and clamp the rail.

[0046] Material: Made of durable stainless steel material, provides a sturdy initial fixation.

[0047] Through this step of mechanical clamping, the positioning and preliminary fixation of the track are achieved, ensuring the basic clamping force.

[0048] Tension mechanism 1

[0049] The tensioning mechanism 1 is the second step of the double positioning, and ensures the stability and anti-clip effect after clamping by further applying tensioning force.

[0050] Articulated seat 101 and pull rod 102:

[0051] The hinge seat 101 is fixed inside the positioning groove 10 and connected to the pull rod 102. The pull rod 102 is allowed to flexibly adjust the angle within a certain range.

[0052] The pull rod 102 includes a trapezoidal slide groove 105 and a trapezoidal slider 106 and can slide along the trapezoidal slide groove 105 .

[0053] Trapezoidal chute 105 and trapezoidal slider 106:

[0054] Design: A trapezoidal sliding block 106 is slidably installed inside the trapezoidal sliding groove 105, which enhances the stability of the sliding process.

[0055] Function: Responsible for any need to adjust the tension during the clamping process to ensure stability after clamping.

[0056] Tension spring 103 and buckle block 104:

[0057] Tension spring 103 : connected to the bottom surface of the trapezoidal sliding block 106 and the trapezoidal sliding groove 105 , and provides additional tensioning force through the tension spring 103 .

[0058] Buckle block 104: After clamping the rail and tightening the spring 103, the buckle block 104 is engaged on the positioning rod 4 to ensure that the tightened state is fixed and not loose.

[0059] Through the action of the tensioning mechanism 1, not only the clamping force of the rail is strengthened, but more importantly, further firm positioning is achieved on the basis of the initial clamping, ensuring that the rail does not move or deform under vibration and dynamic loads.

[0060] Structural combination

[0061] Dual positioning achieves the best results through a combination of these two mechanisms:

[0062] Initial clamping provides basic support: The mechanical clamping function initially fixes the rail and provides basic positioning and support.

[0063] Further tightening to achieve stable positioning: The tightening mechanism 1 provides additional tightening force to ensure that the clamping force will not be weakened due to vibration or load during long-term use, thereby avoiding unclamping.

[0064] This dual positioning ensures that the rail clamp maintains a high level of safety and stability under any working conditions, significantly improving the operational safety and maintenance efficiency of the railway system.

[0065] Working principle: When in use, first place the track between the two clamps 7, then rotate the hand lever 9. The rotation of the hand lever 9 drives the threaded rod 12 to rotate. The rotation of the threaded rod 12 makes the No. 1 clamp 2 move closer to the No. 2 clamp 3, thereby clamping the track. When the clamping is completed, pull the buckle block 104 to stretch the tensioning spring 103, then rotate the pull rod 102 to bend the pull rod 102, and then buckle the buckle block 104 on the positioning rod 4. Under the action of the tensioning spring 103, the clamping between the No. 1 clamp 2 and the No. 2 clamp 3 can be made more stable, thereby increasing the safety of the clamping track and preventing the clamping from occurring.

[0066] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
