Description

Technical Field

[0001] The utility model relates to the technical field of suspension devices, and particularly relates to a fatigue-resistant preformed suspension device. Background Art

[0002] In the environment of high-wind areas, the catenary has shown varying degrees of dancing, which has led to varying degrees of wear on the suspension products of the additional conductors of the electrified railway catenary. In particular, the suspension holes and suspension bolts are severely worn. In severe cases, the suspension holes are worn through and the connecting bolts are worn off, posing a great hidden danger to the operation safety of the catenary.

[0003] The main reason is that the conductor of the additional wire of the catenary swings periodically after being affected by the wind, which drives the suspension parts to swing periodically. During this process, the suspension products rotate around the connecting bolts, generating a continuous periodic semi-circular reciprocating motion. Coupled with the self-weight of the conductor, the wear of the suspension products is accelerated. Based on the above reasons, we provide a fatigue-resistant preformed suspension device, which can effectively dissipate the energy generated by the circular swing of the conductor after being affected by the wind, thus greatly improving the anti-fatigue performance of the additional conductor.

[0004] To solve the above problems, a variety of different suspension devices are provided. Among them, the preformed anti-wear suspension device for electrified railways with the application number 201620912193.2 and the name includes a wear-resistant hanging plate assembly, a preformed suspension clamp and an additional conductor. The wear-resistant hanging plate assembly includes a triangular hanging plate and a double-ear connecting plate, and bearings are respectively arranged on the triangular hanging plate and the double-ear connecting plate. During the actual use of the entire device, along with the wear of the bearings, it is necessary to replace the triangular hanging plate and the double-ear connecting plate on the device. It is necessary to replace two components of the device at the same time, and the replacement process is relatively cumbersome. At the same time, when replacing the components, two kinds of parts need to be equipped in the warehouse at the same time, occupying more space and being not easy to store. Content of the Utility Model

[0005] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a fatigue-resistant preformed suspension device, which is used to solve the problem that in the existing suspension device, bearings are respectively arranged on the triangular hanging plate and the double-ear connecting plate. After the bearings are worn, it is necessary to replace the triangular hanging plate and the double-ear connecting plate at the same time, and the replacement process is relatively cumbersome. At the same time, two kinds of parts, namely the triangular hanging plate and the double-ear connecting plate, need to be stored in the warehouse at the same time, occupying more warehouse space.

[0006] A fatigue-resistant preformed suspension device includes an anti-wear connecting plate, a corner hanging ring and a preformed suspension clamp;

[0007] Bearings are installed at both ends of the corner suspension loop. The bearing at the top of the corner suspension loop is rotatably connected to the wear-resistant connecting plate through a connecting shaft; the bearing at the bottom of the corner suspension loop is rotatably connected to the preformed suspension clamp through another connecting shaft.

[0008] Further, the corner suspension loop includes a suspension loop body. Installation holes are provided at both ends of the suspension loop body for installing the bearings; the bearings are sleeved on the connecting shaft; end caps are provided at both ends of the installation holes; through holes for the connecting shaft to pass through are provided on the end caps.

[0009] Further, double nuts are provided at both ends of the connecting shaft.

[0010] Further, second jack holes are provided at both ends of the connecting shaft for inserting second split pins to prevent the double nuts from disengaging from the connecting shaft.

[0011] Further, the suspension device further includes a shoulder bracket; the shoulder bracket is connected to the wear-resistant connecting plate.

[0012] Further, the shoulder bracket includes a connecting plate and an angle steel; one end of the angle steel is connected to the connecting plate, and the other end is connected to the wear-resistant connecting plate through a bolt assembly.

[0013] Further, a first single ear plate is provided at the top of the wear-resistant connecting plate, and second single ear plates are symmetrically provided at the bottom; the first single ear plate is connected to the shoulder bracket through a bolt assembly; the second single ear plates are connected to the corner suspension loop through a connecting shaft.

[0014] Beneficial effects: No bearings are provided on both the wear-resistant connecting plate and the preformed suspension clamp, and two bearings are installed on the corner suspension loop; when the bearings are worn and need to be replaced, only the corner suspension loop with bearings needs to be replaced, without replacing the wear-resistant connecting plate and the preformed suspension clamp; the replacement of a single component is simpler than replacing two components simultaneously. At the same time, the number of parts equipped in the warehouse becomes half of the original, which can reduce the occupancy of warehouse space by the parts to be equipped and improve the warehouse utilization rate; the reduction in the number of parts to be replaced can also reduce the number of parts produced, thereby reducing resource consumption.

[0022] Next, in combination with the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. For ease of explanation, the terms "vertical", "horizontal", "left", "right", "upper", "lower", "inner", "outer", "bottom", etc. used in this specification indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present application 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 cannot be construed as a limitation of the present application.

[0023] It should be noted that the embodiments in the present utility model and the features involved in the embodiments can be combined with each other without conflict. Based on the embodiments in the present utility model, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present utility model.

[0024] As Figures 1 - 5 shown, a fatigue-resistant preformed suspension device includes a shoulder frame 1, an anti-wear connecting plate 2, a corner hanging ring 3, and a preformed suspension clamp 5;

[0025] The shoulder frame 1 is longitudinally arranged. One end of the shoulder frame 1 is connected to the mounting surface, and an anti-wear connecting plate 2 is connected to the lower side of the other end. Bearings 303 are respectively installed at the top end and the bottom end of the corner hanging ring 3. The bearing 303 at the top end of the corner hanging ring 3 is rotationally connected to the anti-wear connecting plate 2 through a connecting shaft 4, and the bearing 303 at the bottom end of the corner hanging ring 3 is rotationally connected to the preformed suspension clamp 5 through a connecting shaft 4. The bottom of the preformed suspension clamp 5 is used for installing the laterally extending preformed wire 6.

[0026] In this embodiment, bearings 303 are not provided on both the anti-wear connecting plate 2 and the preformed suspension clamp 5, and two bearings 303 are installed on the corner hanging ring 3. When the bearings 303 are worn and need to be replaced, only the corner hanging ring 3 provided with the bearings 303 needs to be replaced, without replacing the anti-wear connecting plate 2 and the preformed suspension clamp 5. The replacement of a single component is simpler than the operation of replacing two components simultaneously. At the same time, the parts equipped in the warehouse become half of the previous ones, which can reduce the occupation of warehouse space and improve the utilization rate of the warehouse. The reduction in the number of parts to be replaced can also reduce the production quantity of parts and lower resource consumption.

[0027] As Figure 2 shown, the shoulder frame 1 includes an angle steel 102 and a connecting plate 101 fixedly connected to one end of the angle steel 102. The connecting plate 101 is connected to the mounting surface by screws.

[0028] In this embodiment, the structure of the shoulder frame 1 is simple, facilitating production and manufacturing. The angle steel 102 is fixedly connected to one side surface of the connecting plate 101, and the overall structure is relatively stable and not easily deformed.

[0029] As Figure 3 shown, a first single ear plate 201 is provided at the top of the anti-wear connecting plate 2, and second single ear plates 202 are symmetrically provided at the bottom. Two first through holes are horizontally spaced on the first single ear plate 201, and a second through hole is provided on the second single ear plate 202. The first through holes are used for arranging bolt assemblies, and the bolt assemblies are used to connect the angle steel 102 and the first single ear plate 201. The bolt assembly includes a screw rod, a nut is provided on the screw rod, and a first insertion hole is provided at one end of the screw rod for a first split pin to be inserted.

[0030] In this embodiment, the structure of the anti-wear connecting plate 2 is simple, facilitating manufacturing and use. The two first through holes are horizontally spaced, and in cooperation with the bolt assemblies, the anti-wear connecting plate 2 can be conveniently fixed to prevent the anti-wear connecting plate 2 from rotating. The first split pin can prevent the nut from loosening and detaching from the screw rod.

[0031] As Figure 4 and Figure 5As shown in the figure, the corner suspension loop 3 includes a suspension loop body 301, a bearing 303 and an end cover 304; mounting holes 302 are respectively arranged at the top and bottom of the corner suspension loop 3, a bearing 303 is arranged in the mounting holes 302, end covers 304 are arranged at both ends of the mounting holes 302, and the end covers 304 are connected to the suspension loop body 301 by screws for limiting the bearing 303 to prevent the bearing 303 from disengaging from the mounting holes 302. The bearing 303 is sleeved on the connecting shaft 4, and both ends of the connecting shaft 4 correspondingly pass through through holes arranged on the end covers 304 and are connected to the abrasion-proof connecting plate 2 or the preformed suspension clamp 5. Double nuts are arranged at both ends of the connecting shaft 4, and the nuts are used to limit the position of the connecting shaft 4 to prevent the connecting shaft 4 from moving, which may cause the disconnection between the corner suspension loop 3 and the abrasion-proof connecting plate 2 or the disconnection between the corner suspension loop 3 and the preformed suspension clamp 5; the setting of the double nuts can prevent loosening. Second jacks are arranged at both ends of the connecting shaft 4, and the second jacks are used for inserting a second split pin, and the second split pin is used to prevent the nut from disengaging from the connecting shaft 4.

[0032] In this embodiment, the structure of the corner suspension loop 3 is simple, which is convenient for production, manufacturing and use.

[0033] Working principle: Connect the shoulder frame 1 of the device to the installation surface, and install the preformed wire 6 on the preformed suspension clamp 5 of the device; the preformed wire 6 drives the preformed suspension clamp 5 to swing periodically. As the swinging progresses, the bearing 303 arranged on the corner suspension loop 3 wears out and needs to be replaced;

[0034] When replacing the corner suspension loop 3, it is necessary to first pull out the second split pins arranged at both ends of the connecting shaft 4, then remove the double nuts arranged at both ends of the connecting shaft 4 by existing tools or by hand, and then pull out the connecting shaft 4 installed on the bearing 303 until the corner suspension loop 3 is disconnected from the abrasion-proof connecting plate 2 and the preformed suspension clamp 5, and then remove the corner suspension loop 3; the new corner suspension loop 3 can be installed through the steps opposite to the above process.

[0035] Although the preferred embodiments of the present invention have been described, those skilled in the art can make additional changes and modifications once they know the basic creative concepts. Therefore, the appended claims are intended to be construed to include the preferred embodiments as well as all changes and modifications falling within the scope of the present invention. Obviously, those skilled in the art can make various changes and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these modifications and variations.
