Description

Technical Field

[0001] The utility model relates to the technical field of railway construction auxiliary equipment, and particularly relates to a ballast retaining block that can be used on both sides. Background Art

[0002] There are usually a lot of ballast stones on the railway subgrade. In order to retain the ballast and protect the roadbed, a ballast retaining plate is usually arranged at the edge of the subgrade for blocking. The existing ballast retaining plates are in the form of concrete. Although they have high strength, due to their large volume and heavy self-weight, they increase the load of the subgrade and reduce the passing weight of heavy-haul railway bridges. There are also ballast retaining plates made of polymer materials, which are lighter in weight. However, due to their light weight, bolts or anchor bolts are required to connect and fix them to the subgrade during installation, holes need to be drilled in the subgrade, the labor intensity is large, and the original structure of the subgrade will also be damaged.

[0003] In addition, whether it is a concrete material or a light material ballast retaining plate, it can only be used on one side, and it is necessary to distinguish between the bottom plate and the vertical plate, and the scene applicability is general. Summary of the Invention

[0030] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present utility model.

[0031] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "middle", "upper", "lower", "left", "right", "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 therefore should not be construed as a limitation of the present utility model. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0032] As Figures 1 to 3 shown, a ballast block that can be used on both sides, the ballast block is used to be installed on the roadbed. The ballast block includes an integrally formed first side plate 1 and a second side plate 2. The first side plate 1 and the second side plate 2 are arranged at an angle. The first side plate 1 or the second side plate 2 is used to be installed on the roadbed; weight-reducing grooves 3 are respectively provided on the inner sides of the first side plate 1 and the second side plate 2, and insertion structures are respectively provided at both ends in the length direction of the first side plate 1 and the second side plate 2. The insertion structure is used to connect adjacent ballast blocks.

[0033] The structure of this ballast block is simple, easy to manufacture and use, and can be conveniently laid in batches on the railway roadbed to block railway ballast; moreover, both sides of the ballast block can be used, and it can be inverted for different heights of ballast, improving the applicable scenarios of the product.

[0034] The first side plate 1 and the second side plate 2 are usually two plates with different widths (heights). In this embodiment, both of these side plates can be used as the bottom plate, and can be applied to roadbeds with different requirements for height and width. For example, when the roadbed to be placed requires a larger bottom support width for the ballast retaining block, the ballast retaining block can be flipped so that the side plate with a larger width (height) can be directly used as the bottom plate. Similarly, when a higher height usage environment is required, the side plate with a larger width (height) can be used as the vertical plate.

[0035] Adopting the splicing method of the plug-in structure facilitates the sequential paving of multiple ballast retaining blocks, enables a row of ballast retaining blocks to be connected to form an integral structure, has better stability, and is more conducive to improving the ballast retaining effect.

[0036] The entire ballast retaining block is a product formed by molding through a mold. The first side plate, the second side plate, and structures such as holes and grooves are all manufactured together. In this embodiment, the ballast retaining block is made of thermosetting polymer materials / thermoplastic polymer materials, and these materials all have good molding processability; for thermosetting polymer materials, such as epoxy resins, bismaleimides, thermosetting polyimides, cyanate esters and other thermosetting resins, they can polymerize at high temperatures to form a hard solid structure, are not easily decomposed or melted, have high heat resistance, and are not easily deformed or softened after curing and molding; for thermoplastic polymer materials, such as polyolefins, polyester plastics, etc., they can be softened and molded at relatively low temperatures, have good plasticity, and are easy to process and mold.

[0037] The setting of the weight reduction groove 3 can reduce the weight of the entire ballast retaining block, facilitate transportation, handling and installation; at the same time, the setting of the weight reduction groove can reduce the use of molding materials and save production costs. The weight reduction groove 3 is provided on both the first side plate 1 and the second side plate 2, increasing the number of weight reduction grooves 3 provided.

[0038] Since in this embodiment, the first side plate 1 or the second side plate 2 is installed on the roadbed by gluing, there is no need to open holes for connecting the roadbed on the first side plate 1 or the second side plate 2. Therefore, the weight reduction grooves can be provided on both side plates.

[0039] During laying, an adhesive 4 can be coated on the bottom of the roadbed or the ballast retaining block to form an adhesive layer, and the ballast retaining block can be directly fixed on the roadbed by pasting, which is more convenient for laying, does not require the use of bolts or anchor bolts for fastening, reduces the labor intensity, and also avoids opening holes in the roadbed. Moreover, when maintaining and replacing the ballast retaining block later, the glue can also be removed, such as by using a glue remover or heating at high temperature (flame gun) to remove the adhesive.

[0040] Further, in combination with Figure 4As shown, the outer sides of the first side plate 1 and the second side plate 2 are respectively provided with a roughing structure or distributed with a number of rough granular bumps 5. It can also be some patterns, fine surface uneven structures, etc.

[0041] The setting of the roughing structure or the rough granular bumps 5 is to increase the roughness and friction coefficient of the side of the first side plate 1 and the second side plate 2 for gluing, so that the adhesive can adhere, and these tiny gaps can also be used to accommodate the adhesive, which is beneficial to improving the firmness of the bonding.

[0042] Further, the width of the first side plate 1 is 250 - 450 mm, the width of the second side plate 2 is 200 - 350 mm, and the thicknesses of both the first side plate 1 and the second side plate 2 are 20 - 50 mm.

[0043] During the production process, various models of ballast blocks can be produced according to the need with an increment of 50 mm in width (or height). For example, the width of the first side plate 1 can be selected as 250 mm, 300 mm, 350 mm, 400 mm, 450 mm, etc., and the width of the second side plate 2 can be selected as 200 mm, 250 mm, 300 mm, 350 mm, etc. The thicknesses of both can be selected as 20 mm, 30 mm, 40 mm, 50 mm, etc. The larger the length and width, the larger the thickness selection.

[0044] Through the above settings, this ballast block can have various combinations, and both side plates can be used as the bottom plate, with relatively high stability.

[0045] Further, the included angle between the first side plate 1 and the second side plate 2 is 85 - 100°. Preferably, the first side plate 1 and the second side plate 2 are arranged perpendicularly.

[0046] Further, as shown in Figure 5 The weight - reducing grooves 3 are rectangular grooves, circular grooves or polygonal grooves arranged in an array.

[0047] Further, as shown in Figure 6 The plug - in structure includes a plug - in groove 6 provided on the same side end faces of the first side plate 1 and the second side plate 2, and a plug - in rib 7 provided on the other same side end face. The plug - in groove 6 and the plug - in rib 7 are respectively arranged in the middle; the plug - in rib 7 on the adjacent ballast block is plugged into the plug - in groove 6 and is fastened by a number of connecting pieces.

[0048] During the assembly process, insert the plug - in rib 7 into the plug - in groove 6 from the side end face so that the two are snap - connected, and further use connecting pieces for fastening according to the need.

[0049] The plugging groove 6 and the plugging rib 7 are respectively provided with connection holes 8 for connecting the connecting piece. The connection hole 8 on the plugging groove is a counterbore, and the connecting piece is a bolt 9 or a limit pin.

[0050] Through the arrangement of the counterbore, the end part of the bolt 9 and the nut can be accommodated, so that the bolt will not protrude when playing the role of connection. It can not only play the role of anti-slip and prevent the bolt from loosening, but also play the role of aesthetics and avoid scratching people or objects by the protruding bolt.

[0051] Further preferably, as Figure 7 shown, several groups of transverse dovetail grooves 10 are further provided on the inner side of the plugging groove 6, and dovetail wedges adapted to the dovetail grooves 10 are provided on the outer periphery of the plugging rib 7.

[0052] Through the cooperation of the dovetail groove 10 and the dovetail wedge, in addition to further improving the connection stability, it also plays a multi-directional limiting role, which can avoid the shaking and separation of the ballast retaining block. At this time, bolts can also not be used, and simple connection can be carried out by using limit pins, and the operation is more convenient.

[0053] In some embodiments, as Figure 8 shown, the plugging structure includes first plugging positions 11 and first plugging plates 12 arranged at both ends of the first side plate 1, and second plugging positions 13 and second plugging plates 14 arranged at both ends of the second side plate 2. The first plugging positions 11 and the second plugging positions 13 are arranged on the inner and outer sides of the ballast retaining block.

[0054] In the above embodiment, another matching plugging structure is provided, so that the first plugging position 11 and the second plugging position 13 on the same side are in two directions of inside and outside, so that it can not only meet the assembly form from top to bottom, but also have a certain limiting ability in the horizontal direction. Adjacent ballast retaining blocks are not easy to shake or shift relatively after splicing, and finally, connection and fastening can also be carried out at the splicing position by bolts.

[0055] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
