Description

Technical Field

[0001] The present invention relates to the technical field of urban rail transit contact rails, and particularly to an anti-slip member applied to contact rails. Background Art

[0002] With the continuous expansion of the subway network in recent years, as an important device for providing normal current collection for trains, the state of the contact rail equipment is directly related to the operation quality and safety of the subway. The lower-contact type contact rail is composed of a steel-aluminum composite rail body and its accessories. Among them, the protective cover belongs to the protective accessory of the body and is supported and fixed on the body by a protective cover support clip. The protective cover is indirectly connected in a lap joint manner, and the lap joint length is not less than 0.1 m; the protective cover support clips are generally arranged at intervals of 0.5 m.

[0003] During the operation of the subway, the dislocation of the contact rail protective cover has been found many times, resulting in the mutual slippage of the lap joint surfaces of the protective covers and the exposure of the conductive rail. At the same time, phenomena such as the lower lap, upward warping, and cracking of the protective cover occur, posing a great safety hazard to train operation; due to reasons such as the construction quality of the spacing of the protective cover support clips and the excessive slope of the line, the distribution of the protective cover support clips is uneven, and even shows a one-way movement, causing the protective cover support clips to stick together, and then causing the other end of the protective cover within the span to lose effective support, resulting in phenomena such as lower lap and upward warping; and in the existing engineering applications, there is no relevant member for ensuring the spacing of the protective cover support clips.

[0004] After retrieval, the publication number CN208452830U - a contact rail protective cover support clip, in order to prevent the protective cover support clip from moving, by setting a rubber anti-slip pad, a rubber anti-slip sheet and an anti-slip part in the card slot, thereby increasing the friction force to prevent it from moving on the track. However, the set rubber material is poor in wear resistance, compressive capacity and the stability of the overall structure; the publication number CN205529727U - a track anti-slip device, when preventing the reinforcement trolley from walking, it is easy to cause the track to slide down along the slope surface. A stop block is connected to the track, and the stop block is adjusted by a support screw rod and fixedly connected with a backing plate. However, it needs to be welded at a certain place below the track, making the track unevenly stressed, and the adaptive removal will affect the existing track structure and strength.

In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "installed", "connected", "connected", "set" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations. The embodiments of the present invention will be described below according to the overall structure of the present invention.

[0024] Please refer to Figures 1-6 , the present invention provides a technical solution: as Figures 1-4As shown in the figure, an anti-slip member applied to a contact rail includes an anti-slip column 1. Blocks 2 are provided at both ends of the anti-slip column 1. Clamping seats 3 are provided on both sides of the middle of the anti-slip column 1. The clamping seat 3 includes a fixing plate 10. The fixing plate 10 is fixedly connected to the anti-slip column 1 through a connecting block 9. First claws 4 and second claws 5 for cooperating with a protective cover support clip 6 are provided at both ends of the fixing plate 10. The first claws 4 and the second claws 5 located on both sides of the anti-slip column 1 are respectively arranged in a crossed manner.

[0025] The anti-slip column 1 is in the shape of a quadrangular prism. The upper and lower surfaces of the clamping seat 3 are flush with the upper and lower surfaces of the anti-slip column 1 respectively, and cooperate with the bayonet 7 of the protective cover support clip 6 to avoid the situation that the anti-slip column 1 rotates due to external factors in the case of a circular design; the upper surface of the block 2 is flush with the upper surface of the anti-slip column 1, and the bottom of the block 2 extends outside the anti-slip column 1. The extended distance of the block 2 takes into account the thickness of the protective cover support clip 6, increases the contact area with the contact rail 8, and improves the stability; as Figure 2 shown in the partial enlarged view, both the first claw 4 and the second claw 5 are perpendicular to the fixing plate 10, and the included angle between the fixing plate 10 and the inner surface of the first claw 4 is an acute angle. The acute angle design is used to hook and fix the protective cover support clip 6; as Figure 5 shown in the structural schematic diagram, the setting position of the connecting block 9 is an optimized design according to the overall structure of the protective cover support clip 6, so that the connecting block 9 is arranged on the side close to the first claw 4, and the structural strength and force distribution of the anti-slip member are more reasonable. When the connecting block 9 is arranged in the middle of the anti-slip member to apply pressure, the structural strength of this part is insufficient, resulting in fatigue fracture or irreversible deformation, leading to the occurrence of events that damage the anti-slip member and the protective cover support clip 6; the included angle of the inner surface of the second claw 5 is a right angle, and there is an inclined surface on the inner surface as a transition surface to make the process of the protective cover support clip 6 entering from the first claw 4 smoother; the material of the anti-slip member is hard plastic or polytetrafluoroethylene, which has a certain elasticity, facilitating the insertion of the first claw 4 and the second claw 5 into the protective cover support clip 6 for installation and firmly combining with the protective cover support clip 6; the anti-slip member is an integral member, with a simple structure and improved structural strength, which can be used for batch processing. The fixing plate 10 can be adaptively adjusted according to the width of the protective cover support clip 6.

[0026] Working principle: As Figure 6As shown, when the contact rail 8 of the present invention is spliced, the protective cover support clip 6 slides in from both sides of the contact rail 8. After adjusting the distance between the protective cover support clips 6, the anti-slip member is inserted through the bayonet 7 of the contact rail 8, and is fixed on the outer wall of the bayonet 7 with the first claw 4 and the second claw 5 to fix the position of the protective cover support clip 6. The distance between the anti-slip members is adjusted so that they are connected front and back. At this time, the lower part of the stopper 2 is arranged on the upper surface of the contact rail 8, and finally the installation of the anti-slip member is completed. The anti-slip member of the present invention can distribute the protective cover support clips 6 at different intervals under different operating environments, so that the forces received by the protective cover support clips 6 are evenly distributed on the contact rail 8, without phenomena such as buckling or warping, ensuring the safe operation of the train.

[0027] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention, and any reference signs in the claims should not be regarded as limiting the claims involved.
