Description

Technical Field

[0001] The utility model belongs to the technical field of accessories for operation, transportation, packaging, storage and handling rails, and in particular relates to a channel steel with a protective cover for fixing the rails. Background Art

[0002] Compared with other profiles, channel steel has the characteristics of stable performance, light weight, simple manufacturing process, and excellent seismic resistance, which makes it widely used and promoted in many fields such as construction, bridges, and rail transit. The application of channel steel in the rail industry not only improves the stability and safety of engineering structures, but also provides solid support for the development of various industries. Therefore, channel steel is a highly adaptable in-plant part.

[0003] With the development of the company, there are more and more urban rail and subway products and products exported overseas, and these users have high requirements for product quality and anti-corrosion. In order to avoid the anti-corrosion paint being scraped off due to the loose binding between rail parts during transportation, a certain amount of channel steel is usually needed to package the rail products.

[0004] On the other hand, from material preparation to production execution to the export of the final product, different projects have different processes and scales. With the increase in orders, the storage of inventory products in the factory also faces considerable pressure. Therefore, the use of channel steel packaging rails effectively reduces the quality and safety risks that may exist when rails are directly stacked.

[0005] However, the channel steel itself is also metal. If the channel steel is directly packed with bolts, washers, and nuts, it will cause contact and wear between the rail and the channel steel itself.

[0006] At present, most of the packaging of channel steel rail parts in the factory is to place two rubber pads at the contact surface of the upper and lower channel steels with the top and bottom surfaces of the rail respectively. However, since the rubber pads are hand-cut, the sizes of the rubber pads vary. In addition, the inertial displacement generated during transportation can easily lead to the phenomenon that the angle between the channel steel and the rubber pad is not completely fitted, which further leads to the misalignment of the fitting angle between the rubber pad and the channel steel, exposing the contact surface between the channel steel and the rail parts and causing wear.

[0007] Therefore, in combination with the patent of a turnout rail assembly protection device with announcement number CN217101256U under the prior art, the traditional channel steel rubber pad packaging has the following problems:

[0008] 1) The rubber pad skin is manually cut according to the channel steel of different sizes. The manual cutting has poor precision and low success rate, which easily leads to waste of rubber pad resources.

[0009] 2) The rubber pad is not fixed to the channel steel. After the rubber pad is displaced, it does not fit the channel steel, and the angle is not aligned. There is a problem of movement friction, which wears the rail parts and easily causes the pad to be damaged. In this regard, the following improved technical solutions are proposed.

[0012] Among the above technical solutions, as the preferred technical solution of the utility model: the elastic pad layer is a rubber pad, or a silicone pad, or a foam pad.

[0030] The following will be combined with the attached embodiment of the present utility model Figure 1-6 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] (like Figure 1 (As shown) A channel steel with a protective cover for fixing rails, comprising an upper channel steel 1 and a lower channel steel 2; the channel steel is used to package the rail 3. On the one hand, as described in the advantages of the background technology: the channel steel has the characteristics of stable performance, light weight, simple manufacturing process, excellent seismic performance, etc. compared with other profiles; and it has been widely used and promoted in many fields such as construction, bridges, and rail transportation; it not only improves the stability and safety of engineering structures, but also provides solid support for the development of various industries. Therefore, the channel steel is a highly adaptable in-plant part. On the other hand, the channel steel material is easy to obtain, economical and practical, and suitable for promotion.

[0032] On this basis: the upper and lower clamps are clamped and restrained between the upper channel steel 1 and the lower channel steel 2, and a rail member 3 is fixed thereto; the utility model adopts a "clamping and restraining" method to protect and fix the rail member 3, and the fixing and restraint is firm and reliable, with a high level of protection.

[0033] (See also Figure 1 ) In addition, in the above embodiment, as a preferred embodiment of the utility model: the upper and lower corresponding through holes are formed on the outer symmetrical sides of the upper and lower channel steels 1 and 2; the upper and lower channel steels 1 and 2 are clamped and constrained to fix the rail members 3 by the tightening bolts 5 that penetrate the upper and lower through holes, using washers 6 and nuts 7. The assembly and fixation of one or two rail members 3 is completed by the restraint and fixation in this way. The fastening assembly composed of the tightening bolts 5, washers 6 and nuts 7 is easy to obtain, economical and practical, simple to assemble, convenient to assemble, firm and reliable, and suitable for promotion.

[0034] On this basis: in order to play an excellent safety protection role and prevent the upper and lower channel steels made of rigid materials from causing friction and damage to the rail member 3, an elastic cushion layer 4 is provided between the rail head 301 and the rail limb 302 of the rail member 3 and the contact surface of the upper and lower channel steels. The elastic cushion layer 4 is used to protect the rail member 3, avoid the occurrence of friction and damage, ensure that the rail member 3 is delivered to the purchaser in good quality, and ensure the company's reputation.

[0035] On this basis, when the rail 3 is in the process of transportation, in order to avoid sliding displacement of the elastic pad 4 due to the inertial force between the elastic pad 4 and the channel steel: the elastic pad 4 is bonded and fixed to the inner sides of the upper and lower channel steels as a whole. On the one hand, the elastic pad 4 has a high degree of fit with the channel steel, and there is no problem of movement friction; on the other hand, the bonding and fixing method of the elastic pad 4 and the channel steel does not require hole making compared to the fastening and fixing method of the elastic pad 4, and retains the integrity of the elastic pad 4. At the same time, the elastic pad 4 can contact the surface of the rail 3 without rigid parts, avoiding wear of the rail 3 and not easily causing damage to the elastic pad 4 itself.

[0036] On this basis: the size of the elastic cushion layer 4 is closely matched with the size of the inner side of the upper and lower channel steels. That is, the elastic cushion layer 4 is made by an industrial method without manual cutting. The industrial production method of the elastic cushion layer 4 has high dimensional accuracy and is suitable for mass production, avoiding waste of the elastic cushion layer 4 material.

[0037] In the above embodiment, as the preferred technical solution of the utility model: the elastic pad 4 is a rubber pad, a silicone pad, or a foam pad. When used specifically, any two elastic pads 4 of different materials can be used in combination or the same material can be used.

[0038] In the above embodiment, as a further improvement of the utility model, the thickness of the elastic cushion layer 4 is at least 5 mm. No matter what material is used, the thickness of the elastic cushion layer 4 is not less than 5 mm, ensuring the elastic cushion layer 4 to perform its best function and durability.

[0044] Based on the above embodiments, as the preferred technical solution of the utility model: the U-shaped grooves of the upper channel steel 1 and the lower channel steel 2 are both arranged back to the rail member 3. That is, the lower channel steel 2 plays a role of padding and supporting the rail limb 302 of the rail member 3, and the upper channel steel 1 plays a role of anti-collision and shielding support for the rail head 301.

[0045] The assembly and protection principle of the utility model is as follows: (such as Figure 4 As shown) insert the lower channel steel 2 under the rail member 3, place the upper channel steel 1 on the upper side of the rail member 3, and arrange at least three sets of the utility model (combined with Figure 2 ). When packaging constraints: (such as Figure 1 As shown in the figure, use the tension bolt 5 to pass through the through hole of the lower channel steel 2, and then pass the tension bolt 5 out of the through hole of the upper channel steel 1, then set the washer 6 on the through end of the tension bolt 5, and then use the nut 7 to tighten it. During the continuous tightening process of the nut 7, the rail 3 is clamped and fixed between the upper and lower channel steels. (As shown in the figure Figure 4 As shown, since the U-shaped grooves of the upper and lower channel steels are both arranged to face away from the rail member 3, the lower channel steel 2 plays a supporting role in raising the rail limb 302 of the rail member 3, and the upper channel steel 1 plays a supporting role in preventing collision, shielding and protecting the rail head 301.

[0046] From the above description, it can be found that: the utility model adopts upper and lower channel steel upper and lower clamps to clamp and constrain the fixed rail member 3, retaining the advantages of the channel steel packaging rail member 3 described in the background technology; the elastic pad layer 4 obtained by industrial cutting can fit well with the channel steel, and the elastic pad layer 4 is fixedly connected to the channel steel by bonding, which effectively avoids the displacement of the elastic pad layer 4 under the action of transportation inertia force, improves the stability of the elastic pad layer 4 in use, and ensures the protective effect; the elastic pad layer 4 obtained by industrial cutting avoids the problem of material waste of the elastic pad layer 4 caused by manual cutting.

[0047] Moreover, the elastic pad 4 of the utility model is a rubber pad, a silicone pad, or a foam pad. When in use, any two elastic pads 4 of different materials can be used in combination or the same material can be used; the thickness of the elastic pad 4 is selected according to the different materials, but no matter what material is used, the thickness of the elastic pad 4 is not less than 5mm, ensuring the elastic pad 4 to perform its best function and durability.

[0048] In addition, the working surface of the elastic cushion layer 4 of the utility model is provided with a wear-resistant coating, which further improves the service life of the elastic cushion layer 4.

[0049] Finally, the upper and lower channel steels of the utility model adopt tensioning bolts 5, washers 6, and nuts 7, and the rail member 3 is constrained and fixed by continuously screwing the nuts 7 to gradually tighten and constrain the fixed rail member 3. The assembly operation is simple and convenient, the parts and materials are easy to obtain, it is economical and practical, and the clamping is reliable.
