Description

Technical Field

[0001] The utility model relates to the technical field of rail clamps, and more specifically, to a lightweight reinforced anti-loosening rail clamp. Background Art

[0002] A rail clamp is a product used to tightly fix rails. It is usually welded on an I-beam, and sometimes also used on a steel plate embedded in concrete. With the widespread application of rail transportation and conveying equipment in the industrial and transportation fields, the stable operation of the rails is relied on. If the stability of the rails is poor, there are likely to be significant safety hazards. Moreover, for most existing rail clamps, due to the large operating pressure and poor operating environmental conditions, with the accumulation of usage time, the fastening bolts and nuts in the rail clamp are prone to loosen, resulting in poor stability of the rails and thus likely to cause safety hazards, and also increasing the labor maintenance cost.

[0003] 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

[0004] The purpose of the utility model is to solve the above problems and design a lightweight reinforced anti-loosening rail clamp.

[0005] To achieve the above purpose, the technical solution of the utility model is as follows: A lightweight reinforced anti-loosening rail clamp includes a mounting plate, the mounting plate is welded on the I-beam, a pressing block is arranged above the mounting plate, the pressing block and the mounting plate are connected by a connecting mechanism, and a limiting mechanism is installed on the mounting plate;

[0006] The connecting mechanism includes a first threaded hole at the upper end of the pressing block, a rotating cylinder is connected in the first threaded hole by thread, an internal thread is arranged in the rotating cylinder, an external thread is arranged on the outer side of the rotating cylinder, a rotating screw is connected in the rotating cylinder by thread, the thread direction of the rotating screw is opposite to that of the first threaded hole, a circular through hole is opened at the lower end of the first threaded hole, and the lower end of the rotating screw passes through the circular through hole and is rotatably connected with the mounting plate;

[0007] The limiting mechanism includes a square groove opened at the upper end of the mounting plate, a limiting hole is opened on the rotating screw, a limiting rod is installed in the square groove, and the limiting rod can pass through the limiting hole.

[0008] Furthermore, a second threaded hole is opened on the mounting plate, the second threaded hole is located at the lower end inside the square groove, and the lower end of the rotating screw is connected into the second threaded hole by thread.

[0009] Furthermore, a hexagonal groove is opened at the upper end of the rotating screw.

Detailed Implementation Modes

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0020] 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 accompanying drawings. It 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 to the present utility model. In addition, in the description of the present utility model, the meaning of "a plurality of" is two or more, unless otherwise specifically defined.

[0021] The present utility model provides a lightweight reinforced anti-loosening rail press as shown in Figures 1-4 Figure 8, which includes a mounting plate 1 welded to the I-beam. There is a pressing block 2 above the mounting plate 1, and the pressing block 2 and the mounting plate 1 are connected by a connecting mechanism. A limiting mechanism is installed on the mounting plate 1; the connecting mechanism includes a first threaded hole 3 at the upper end of the pressing block 2. A rotating cylinder 4 is connected to the first threaded hole 3 by a thread. The rotating cylinder 4 has an internal thread, and an external thread is provided on the outer side of the rotating cylinder 4. A rotating screw 5 is connected to the rotating cylinder 4 by a thread. The thread directions of the rotating screw 5 and the first threaded hole 3 are opposite. A circular through-hole 6 is opened at the lower end of the first threaded hole 3. The lower end of the rotating screw 5 passes through the circular through-hole 6 and is rotatably connected to the mounting plate 1; the limiting mechanism includes a square groove 7 opened at the upper end of the mounting plate 1. A limiting hole 8 is opened on the rotating screw 5. A limiting rod 9 is installed in the square groove 7, and the limiting rod 9 can pass through the limiting hole 8.

[0022] The process of preventing loosening of this rail clip is as follows: Weld the mounting plate 1 to the I-beam, connect the lower end of the rotating screw 5 to the mounting plate 1, screw the rotating cylinder 4 to the bottom of the first threaded hole 3 through threaded connection, place the pressing block 2 on the mounting plate 1, and make the upper end of the rotating rod 5 pass through the circular through-hole 6 and contact the internal thread inside the rotating cylinder 4. Then rotate the rotating screw 5, and through the threaded connection between the rotating screw 5 and the internal thread, the pressing block 2 and the rotating cylinder 4 can be moved downward. When the pressing block 2 contacts and presses against the mounting plate 1, stop rotating the rotating screw 5, and make the limiting hole 8 rotate to the side corresponding to the position of the limiting rod 9. Then insert the limiting rod 9 into the square groove 7 to limit the rotating screw 5, and the rotating screw 5 will not rotate anymore. Thus, this device can be installed. Then, during use, due to vibration, the rotating cylinder 4 has a tendency to rotate. If the rotating cylinder 4 rotates clockwise, the rotating cylinder 4 can move downward relative to the first threaded hole 3, but the rotating cylinder 4 moves upward relative to the rotating screw 5, and the two form a self-locking. Therefore, the rotating cylinder 4 cannot rotate. If the rotating cylinder 4 rotates counterclockwise, through the threaded connection between the rotating cylinder 4 and the rotating screw 5, the rotating cylinder 4 can move downward relative to the rotating screw 5, but the downward movement of the rotating cylinder 4 relative to the rotating screw 5 will instead press the pressing block 2 tightly. Therefore, the self-locking of the threaded connection can prevent the rotating cylinder 4 from rotating, and thus prevent the rail clip from loosening.

[0023] Refer to the appended drawings of the specification Figure 1 , the appended drawings of the specification Figure 2 and the appended drawings of the specification Figure 3 , a second threaded hole 10 is opened on the mounting plate 1, and the second threaded hole 10 is located at the lower end inside the square groove 7. The lower end of the rotating screw 5 extends into the second threaded hole 10 through threaded connection. Through the second threaded hole 10, the lower end of the rotating screw 5 can be located inside the second threaded hole 10. Then, the circular through-hole 6 on the pressing block 2 is sleeved on the upper end of the rotating screw 5, and the staff compacts the pressing block 2 against the mounting plate 1. Then rotate the rotating screw 5 and make the upper end of the rotating screw 5 connect with the internal thread on the rotating cylinder 4, and thus the mounting plate 1 and the pressing block 2 can be connected. After the connection is completed, limit the rotating screw 5, and then rotate the pressing block 2. Since the rotating screw 5 will not rotate and the pressing block 2 is already in close contact with the mounting plate 1, the gap between the threads can be reduced. Then loosen the rotating screw 5, turn the pressing block 2 back to its original position, and then limit the rotating screw 5 again and rotate the pressing block 2. After repeating this several times, the pressing block 2 will not loosen.

[0024] Refer to the appended drawings of the specification Figure 1 , the appended drawings of the specification Figure 2 and the appended drawings of the specification Figure 3, a hexagonal groove 11 is formed at the upper end of the rotating screw rod 5, and an internal hexagonal wrench can be inserted into the hexagonal groove 11 from above, facilitating the rotation of the rotating screw rod 5.

[0025] Refer to the appended Figure 1 , the appended Figure 2 and the appended Figure 3 , the limiting rod 9 includes a square block 12 located in the square groove 7. One end of the square block 12 is provided with an intercepting rod 13, and the intercepting rod 13 can pass through the limiting hole 8. A fixing block 14 is installed at one end of the square groove 7 away from the square block 12, and a guiding hole 15 is formed in the fixing block 14. The intercepting rod 13 can pass through the guiding hole 15. By placing the square block 12 into the square groove 7, inserting the intercepting rod 13 into the limiting hole 8, and then passing the intercepting rod 13 through the guiding hole 15, it is convenient to limit the rotating screw rod 5.

[0026] Refer to the appended Figure 1 , the appended Figure 3 and the appended Figure 4 , a positioning hole 16 is formed in the intercepting rod 13, and a pin 17 is installed on the fixing block 14. The pin 17 can be inserted into the positioning hole 16 from top to bottom. By inserting the lower end of the pin 17 into the positioning hole 16, it can prevent the intercepting rod 13 from disengaging from the limiting hole 8.

[0027] Although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
