Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rail clamps, and more specifically, to a high-stability rail pad for fixing rails. Background Technique
[0002] A rail clamp is also called a welded rail clamp, a welded steel rail fixing device, a steel beam rail clamp, a welded pressing plate, and its function is to press and fix the steel rail.
[0003] In the prior art, the pressing plate is generally installed on the mounting plate by bolt connection. However, during use, due to the action of vibration force, the nut is likely to rotate, which in turn causes the bolt connection to become loose, and then a gap is generated between the pressing plate and the rail, resulting in a poor fixing effect on the rail.
[0004] It should be noted that the above content belongs to the technical cognition scope of the inventor and does not necessarily constitute the prior art. Content of the Utility Model
[0005] The purpose of the utility model is to solve the above problems and design a high-stability rail pad for fixing rails.
[0006] To achieve the above purpose, the technical solution of the utility model is a high-stability rail pad for fixing rails, which includes a mounting plate. The lower end of the mounting plate is welded to the I-beam. A fixing screw is installed at the upper end of the mounting plate. A pressing plate is arranged above the mounting plate. A round hole is opened on the pressing plate. The round hole is sleeved outside the fixing screw. The upper end of the fixing screw is threadedly connected with a fixing nut. A limiting mechanism is arranged on the pressing plate. The limiting mechanism includes a hexagonal groove located outside the round hole. A hexagonal sleeve is sleeved outside the fixing nut. The inner side of the hexagonal sleeve is a hexagonal through hole. The hexagonal through hole and the fixing nut are of a matching size. A baffle is installed at the upper end of the hexagonal sleeve. A fixing hole is opened on the baffle. A limiting frame is installed in the hexagonal groove. The limiting frame can limit the hexagonal sleeve.
[0007] Further, the limiting frame includes a plurality of spring ejector pins installed outside the hexagonal groove. A pulley is installed at the telescopic end of the spring ejector pin. A plurality of limiting holes are opened at the lower end of the hexagonal sleeve. An inclined plate is installed at the lower end of the hexagonal sleeve.
[0008] Further, a circular ring sealing ring is installed on the lower surface of the inner side of the baffle.
[0009] Advantages of the present utility model: After the pressing plate is installed by bolt connection, a hexagonal sleeve is installed outside the nut. The lower end of the hexagonal sleeve extends into the hexagonal groove, thereby preventing the hexagonal sleeve from rotating. The hexagonal sleeve can limit the nut, thereby preventing the nut from rotating, ensuring the stability of the bolt connection, and enabling the pressing plate to firmly press the track, making it safer to use.

Detailed Embodiment
[0014] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0015] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present utility model. In addition, in the description of the present utility model, the meaning of "a plurality" is two or more, unless otherwise specifically defined.
[0016] The present utility model provides as Figures 1-3A highly stable track pad for fixing tracks is shown, which includes a mounting plate 1. The lower end of the mounting plate 1 is welded to the I-beam. The upper end of the mounting plate 1 is provided with a fixing screw 2. Above the mounting plate 1, there is a pressing plate 3. A round hole 4 is opened on the pressing plate 3. The round hole 4 is sleeved outside the fixing screw 2. The upper end of the fixing screw 2 is threadedly connected with a fixing nut 5. A limiting mechanism is arranged on the pressing plate 3. The limiting mechanism includes a hexagonal groove 6 located outside the round hole 4. A hexagonal sleeve 7 is sleeved outside the fixing nut 5. The inner side of the hexagonal sleeve 7 is a hexagonal through hole 8. The hexagonal through hole 8 and the fixing nut 5 are of a matching size. A baffle 9 is installed at the upper end of the hexagonal sleeve 7. A fixing hole 10 is opened on the baffle 9. A limiting frame 11 is installed in the hexagonal groove 6. The limiting frame 11 can limit the hexagonal sleeve 7;
[0017] The process of fixing the track by this device is as follows: Weld the mounting plate 1 to the I-beam. Pass the round hole 4 on the pressing plate 3 through the fixing screw 2 and place it on the mounting plate 1. Then screw the fixing nut 5 onto the fixing screw 2, and thus the pressing plate 3 can be fixed to the mounting plate 1. When screwing the fixing nut 5, screw it to a position corresponding to the shape of the hexagonal groove 6. Then sleeve the hexagonal sleeve 7 outside the fixing nut 5. Extend the lower end of the hexagonal sleeve 7 into the hexagonal groove 6. Limit the hexagonal sleeve 7 through the hexagonal groove 6. Limit the fixing nut 5 through the hexagonal through hole 8 inside the hexagonal sleeve 7, and thus prevent the fixing nut 5 from rotating due to vibration, which can ensure the stability of the use of the rail press. The hexagonal sleeve 7 can be limited through the limiting frame 11, and the upward movement of the hexagonal sleeve 7 can be prevented. The baffle 9 can protect the upper end of the fixing nut 5.
[0018] Refer to the attached Figure 1 of the specification, Figure 2 and the attached Figure 3 of the specification,
[0019] The process of the limiting frame 11 limiting the hexagonal sleeve 7 is as follows: Sleeve the hexagonal sleeve 7 outside the fixing nut 5. Then push the hexagonal sleeve 7 downward. When the lower end of the inclined plate 15 contacts the pulley 13, the pulley 13 can be pushed to one side and the spring ejector pin 12 can be compressed. When the limiting hole 14 moves to one side of the pulley 13, under the elastic force of the spring ejector pin 12, the pulley 13 can be pushed into the limiting hole 14, and thus the hexagonal sleeve 7 can be limited.
[0020] Refer to the attached Figure 1 of the specification Figure 2, a circular ring seal 16 is installed on the inner lower surface of the baffle 9. After the hexagonal sleeve 7 is limited, the circular ring seal 16 at the lower end of the baffle 9 can squeeze the fixing nut 5 to prevent the fixing nut 5 from loosening.
