The cable trenches provide space for cable wiring and also provide external protection for the cables, thereby extending the service life of the cables and improving safety.

[0003] At present, the existing cable trenches usually have multiple parallel grooves, and several cover plates are placed on the grooves and along their length. The grooves of the cable trenches are sealed by the cover plates, which can not only make the trench base flatter and facilitate evacuation, but also serve as a protective structure for the cables. In addition, the cables can be hidden, improving neatness and safety, and the cable trenches can be opened during subsequent maintenance and repairs to meet operational needs. However, the cover plate structure used for cable trenches on the market is relatively simple, such as the attached Figure 1 The existing cable trench cover shown in the structural diagram is only a plate-like structure. When installed, the two ends are overlapped and embedded in the grooves on both sides of the notch of the cable trench. Although it can meet the use requirements of sealing the notch of the cable trench, it lacks a fixed structure, that is, after the cover is installed, the road base is not completely horizontal, and it is easily displaced due to the influence of external environment such as vibration during subsequent use. In addition, the existing cable trench cover usually has only one tool hole, which is convenient for the subsequent opening of the cover by passing a tool with a hook structure through the tool hole and hooking the cover to lift and open the cover, resulting in a part on the cover that is directly connected to the cable trench, thereby affecting the protective ability of the cover.

DETAILED DESCRIPTION

[0028] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the following embodiments are combined with the attached Figure 2 To Attachment Figure 6 The technical solution provided by the utility model is described in detail, but the following content is not intended to limit the utility model.

[0029] Figure 2 This is a structural diagram of an embodiment of a cable trench cover for rail transit of the utility model; Figure 3 The figure is a schematic diagram of the installation of a cable trench cover for rail transit according to the utility model. Figure 1 and Figure 2 As shown, the cable trench cover for rail transit provided in this embodiment is installed in the cable trench 1 on the roadbed. At this time, a plurality of isolation walls 11 are arranged in the cable trench 1 and along its length direction. The isolation walls 11 divide the cable trench 1 into a plurality of parallel grooves 12. Cables of different functions or types are arranged through different grooves 12 to meet the needs of distinguishing and isolating wiring. In addition, recessed embedding grooves 13 are provided at the notches on both sides of the cable trench 1, which provide a retaining edge for the subsequent installation of the cover plate, realize support for the cover plate, and also realize the embedded arrangement of the cover plate, ensuring the flatness of the surface. In addition, the cable trench 1 cover for rail transit provided in this embodiment includes: a cover plate body 2, a locking assembly 3, and a hidden flip cover assembly 4.

[0030] Specifically, the cover body 2 is arranged in a plate shape, that is, the cover body 2 has a large paving area, so that it can be used as the main structure for covering the slot of the cable trench 1 in the future. In addition, fixing holes 21 are opened at both ends or the middle of the cover body 2, so that the cover body 2 can be restricted through the fixing holes 21 after installation, thereby providing conditions for improving the stability and reliability of the cover body 2 after installation.

[0031] Specifically, the locking assembly 3 includes an embedded part 31 and a locking part. During installation, the embedded part 31 is pre-embedded in the embedded groove 13 or in the partition wall 11, and one end of the embedded part 31 is extended to the embedded groove 13 or outside the partition wall, so as to facilitate the subsequent connection with the cover body 2 and the locking part. In addition, the cover body 2 is arranged at the notch of the cable groove 1 to cover the notch of the cable groove 1. In addition, the two ends of the cover body 2 are overlapped in the embedded grooves 13 on both sides of the cable groove 1, so as to ensure that the surface of the cover body 2 will not protrude after installation and can be supported by the bottom of the embedded groove 13, so as to achieve stable installation. At the same time, the extended end of the embedded part 31 is inserted into the fixing holes 21 at both ends or in the middle of the cover body 2. At this time, the locking part is installed on the extended end of the embedded part 31, and the cover body 2 is pressed by the locking part, so as to achieve stable and reliable installation of the cover body 2, and prevent the problem of movement due to external influences during subsequent use.

[0032] Specifically, a concave cavity 22 is also provided on the upper surface of the cover body 2, that is, a receiving chamber is formed on the cover body 2 through the concave cavity 22, which provides space for the subsequent installation and operation of the hidden flip assembly 4. At the same time, a tool hole 23 is also provided at the bottom of the concave cavity 22, that is, the tool hole 23 used with the tool for opening the cover body 2 is hidden in the concave cavity 22, which provides conditions for the subsequent hidden flip assembly 4 to open or cover the tool hole 23. In addition, the hidden flip assembly 4 is installed in the concave cavity 22, and after the hidden flip assembly 4 is installed in the concave cavity 22, the cavity opening of the concave cavity 22 can be opened or closed by the hidden flip assembly 4, thereby meeting the use requirements of opening or covering the tool hole 23.

[0033] Figure 4 This is a schematic diagram of the coordination of the upper and lower pressure strips when installing a cable trench cover for rail transit according to the utility model. Figure 2 , Figure 3 as well as Figure 4As shown, a lower pressure strip 24 and an upper pressure strip 25 are respectively provided on both sides of the cover body 2. At this time, the lower pressure strip 24 is formed by extending the lower edge of one side of the cover body 2 by a predetermined distance, and the upper pressure strip 25 is formed by extending the upper edge of the other side of the cover body 2 by a predetermined distance, that is, in the thickness direction of the cover body 2, the upper pressure strip 25 and the lower pressure strip 24 are staggered. When the two adjacent cover bodies 2 are subsequently installed and in place, the upper pressure strip 25 of the previous cover body 2 is pressed against the lower pressure strip 24 of the next cover body 2, that is, the upper pressure strip 25 and the lower pressure strip 24 are overlapped to achieve the side overlap of the two adjacent cover bodies 2, so that the integrity of the two adjacent cover bodies 2 is better, the stability and reliability of the cover body 2 after installation are further improved, and the movement of the cover body 2 after installation is further prevented. At the same time, the installation gap between the two adjacent cover bodies 2 is sealed to avoid the problem of direct connection with the outside world affecting the protection effect.

[0034] More specifically, a plurality of limiting protrusions 241 are provided on the top surface of the lower pressure strip 24 of the cover body 2. At the same time, a plurality of limiting slots 251 corresponding to the limiting protrusions 241 are opened on the bottom surface of the upper pressure strip 25 of the cover body 2. When the two adjacent cover bodies 2 are subsequently installed in place, and when the upper pressure strip 25 of the previous cover body 2 is pressed against the lower pressure strip 24 of the subsequent cover body 2, the plurality of limiting protrusions 241 on the lower pressure strip 24 are embedded one by one into the plurality of limiting slots 251 of the corresponding upper pressure strip 25, that is, an alternatingly interlocking matching structure is formed by the limiting protrusions 241 and the limiting slots 251, which further improves the integrity and stability of the cover body 2 after installation and avoids relative movement of the cover body 2.

[0035] Figure 5 This is a structural diagram of a reinforcement layer of a cable trench cover for rail transit according to the utility model. Figure 2 , Figure 3 as well as Figure 5 As shown, each cover body 2 includes a reinforcing layer 26 and a wrapping layer 27. At this time, the wrapping layer 27 is a plate-like structure, that is, the wrapping layer 27 serves as the main plate surface structure. Preferably, the wrapping layer 27 is made of composite materials, which can improve the corrosion resistance, aging resistance and fire resistance while reducing the weight. In addition, the reinforcing layer 26 is a metal mesh structure interwoven vertically and horizontally. At this time, the reinforcing layer 26 is completely embedded in the wrapping layer 27, that is, the reinforcing layer 26 is completely wrapped by the wrapping layer 27, and the structural strength of the cover body 2 is improved by the reinforcing layer 26, so that the bearing capacity is stronger and the service life is longer.

[0036] More specifically, a plurality of anti-skid protrusions 28 and identification patterns 29 are provided on the upper surface of the cover body 2. At this time, the anti-skid protrusions 28 enhance the friction coefficient of the upper surface of the cover body 2, and the cover body 2 can be used as an evacuation platform to improve safety. In addition, the identification pattern 29 can facilitate subsequent maintenance personnel to timely identify the type of structure arranged in the cable trench 1 below it, which is convenient for later maintenance and repair.

[0037] More specifically, when the horizontal width of the isolation wall 11 in the cable trench 1 is greater than or equal to 100 mm, a fixing hole 21 is opened in the middle of the cover body 2 used, and at the same time, the embedded part 31 is embedded in the isolation wall 11, that is, the isolation wall 11 has sufficient width to install the embedded part 31 and can ensure the installation reliability of the embedded part 31, so that the embedded part 31 only needs to be connected to the fixing hole 21 in the middle of the cover body 2, reducing the number of embedded parts 31 and fixing holes 21, realizing the middle fixation of the cover body 2, and facilitating processing and installation. In addition, when the horizontal width of the isolation wall 11 is less than 100 mm, fixing holes 21 are opened at both ends of the cover body 2. At this time, the embedded parts 31 are embedded in the grooves 13. Since the isolation wall 11 here does not have enough width to install the embedded parts 31 or the installation reliability of the embedded parts 31 cannot be guaranteed, the fixing holes 21 are set at both ends of the cover body 2, and the embedded parts 31 are also set in the grooves 13 on both sides of the cable groove 1, so that the end parts of the cover body 2 are fixed, and the stable installation requirements are also met. Therefore, the cover body 2 and installation method with suitable structure can be selected according to different usage scenarios, which has better adaptability.

[0038] Figure 6 This is a structural diagram of a hidden flip cover assembly of a cable trench cover for rail transit according to the utility model. Figure 2 , Figure 4 as well as Figure 6As shown, the hidden flip cover assembly 4 disposed in the concave cavity 22 of the cover body further includes a flip cover 41, a rotating shaft 42 and a torsion spring 43. At this time, the concave cavity 22 on the cover body is a rectangular structure, so that the concave cavity 22 has a certain length, which provides space for the subsequent flipping of the flip cover 41. In addition, a stopper 44 protruding into the concave cavity 22 is disposed on the inner wall at one end in the length direction of the concave cavity 22, and a blocking structure is formed in the corresponding end of the concave cavity 22 through the stopper 44, and a rotating shaft 42 is placed horizontally at the cavity opening in the middle of the concave cavity 22, which provides support for the subsequent installation of the flip cover 41. In addition, the flip cover 41 is also set to a rectangular structure, and the flip cover 41 is arranged at the cavity opening of the concave cavity 22 in the same direction, so that the flip cover 41 covers the entire concave cavity 22. During installation, the middle part of the bottom surface of the flap 41 is rotated and installed on the rotating shaft 42, so that the two ends of the flap 41 can be turned around the rotating shaft 42, thereby realizing the state that one end of the flap 41 is tilted and the other end is sunken. In addition, the torsion spring 43 is sleeved on the rotating shaft 42, and the two ends of the torsion spring 43 are respectively abutted against the flap 41 and the cavity wall of the concave cavity 22, and the torsion spring 43 provides a reset force for the flipping of the flap 41. During use, when the tool hole 23 is not used normally, the flap 41 is in a state parallel to the upper surface of the cover body 2 under the action of the torsion spring 43. At this time, one end of the flap 41 contacts the limit block 44, and the flap 41 is supported by the limit block 44 to prevent the flap 41 from over-turning, and can avoid the tool hole 23 from being directly connected to the outside world, thereby improving the protection effect. When the tool hole 23 is needed to open the flip cover 41, it is necessary to manually press down one end of the flip cover 41 away from the limit block 44. At this time, the torsion spring 43 is twisted and one end of the flip cover 41 is separated from the limit block 44, so that one end of the flip cover 41 can be flipped out of the cavity 22, thereby exposing the tool hole 23 in the cavity 22, making it convenient for maintenance personnel to insert the tool into the tool hole 23 to open the cover body 2, and the structural design is more reasonable.

[0039] More specifically, a socket 45 is further provided on the side wall of the cavity 22 at one end away from the limit block 44. At this time, a pin is selectively installed in the socket 45, and when one end of the flip cover 41 is pressed down to the bottom of the cavity 22, the pin is inserted into the socket 45. That is, when it is necessary to expose the tool hole 23, one end of the flip cover 41 can be pressed down, and the pin is inserted into the socket 45 after pressing down. The end of the flip cover 41 after being pressed down is limited by the pin, thereby avoiding the problem that the tool hole 23 is covered due to the automatic reset of the flip cover 41 under the action of the torsion spring 43 after loosening the flip cover 41, so that the tool hole 23 is continuously exposed, which is convenient for maintenance personnel to operate.

[0040] More specifically, the fixing holes 21 used to fix the cover body 2 are all countersunk holes, which are convenient for subsequent installation with the embedded parts 31 and when locked by the locking parts, the ends of the embedded parts 31 and the locking parts can be hidden in the countersunk holes, ensuring the surface flatness of the cover body 2. In addition, the embedded parts 31 can be expansion bolts, and the locking parts can be locking nuts, which meet the use requirements of fast installation of the embedded parts 31, and also enable the locking parts to be disassembled, meeting the use requirements of installation and opening of the cover body 2.

[0041] More specifically, a reinforcing portion 46 is further provided on the cover body 2 and on the bottom of the concave cavity 22. At this time, the reinforcing portion 46 is annularly sleeved on the outside of the tool hole 23. The reinforcing portion 46 is a gasket, which is also embedded in the wrapping layer 27. The structural strength of the tool hole 23 is increased by the reinforcing portion 46, so that when the tool hole 23 is used in conjunction with the tool in the subsequent use, the tool hole 23 can be protected from damage, and the structural design is more reasonable.

[0042] The cable trench cover for rail transit provided in this embodiment includes a cover body 2, a locking assembly 3 and a hidden flip assembly 4; by opening a fixing hole 21 in the middle or both ends of the cover body 2, the locking assembly 3 is installed in the partition wall 11 of the cable trench 1 or the embedded groove 13 at the notch, and the fixing hole 21 and the locking assembly 3 are used to realize the stable installation of the cover at the notch of the cable trench 1, thereby improving the stability and reliability of the cover after installation, and effectively avoiding the problem of displacement of the cover due to the influence of the external environment during use. In addition, the tool hole 23 is set in the concave cavity 22 on the cover body 2, and a hidden flip assembly 4 is set at the cavity mouth of the concave cavity 22, and the tool hole 23 is covered or opened by the hidden flip assembly 4, which can not only meet the use requirements of exposing the tool hole 23 to facilitate opening of the cover, but also realize the covering of the tool hole 23 when the tool hole 23 is not needed, so as to prevent the tool hole 23 from being completely connected to the outside world when not in use and affecting the protection, thereby improving the protection capability of the cover.

[0043] The above are only preferred embodiments of the present invention, and do not limit the implementation mode and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
