Based on the embodiments in 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.

[0026] According to an embodiment of the utility model, a tray-type cable tray is provided.

[0027] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods. Figure 1-Figure 7 As shown, the tray-type cable bridge according to the embodiment of the utility model includes a tray bridge 1, the top of the tray bridge 1 is connected to a cover plate 3 through a snap-on assembly 2, a plurality of groups of cable limiting assemblies 4 are arranged on the top of the cover plate 3, and two groups of auxiliary assemblies 5 are arranged inside the tray bridge 1.

[0028] In one embodiment, for the above-mentioned snap-in assembly 2, the snap-in assembly 2 includes a limit plate 201 installed on both sides of the cover plate 3 and a limit groove 202 opened at the top of the tray bridge 1, and a snap-in groove 203 is opened on one side of the limit plate 201 and the tray bridge 1; the snap-in assembly 2 also includes a snap-in block 204 installed inside the snap-in groove 203, and the snap-in block 204 is a cross-shaped structure, and a pull block 205 is provided on one side of the snap-in block 204, so that the assembly between the tray bridge 1 and the cover plate 3 can be made faster and easier through the snap-in block 204 and the snap-in groove 203, ensuring that the two are easily snapped together without a lot of installation work, and it is convenient to remove the cover plate 3 after long-term use to inspect the cables inside the tray bridge 1.

[0029] The working principle of the snap-in assembly 2 is as follows: the limit plates 201 on both sides of the cover plate 3 are snapped into the limit grooves 202 at the top of the tray bridge 1, thereby connecting the two together. At the same time, in order to ensure the stability during snapping, the snap-in block 204 is snapped into the inside of the snap-in groove 203 to improve the tightness of the snap-in connection.

[0030] In one embodiment, for the above-mentioned cable limiting assembly 4, the cable limiting assembly 4 includes a mounting frame 401 installed on the top of the cover plate 3, two groups of connecting frames 402 are arranged inside the mounting frame 401, and worms 403 are arranged inside the two groups of connecting frames 402. Specifically, the outer side of the worm 403 is provided with a plurality of spiral teeth, and a knob 404 is arranged on one side of the worm 403; the cable limiting assembly 4 also includes a plurality of groups of rotating shafts 405 installed on the top of the cover plate 3, the outer side of the rotating shaft 405 is sleeved with a worm wheel 406 matching the worm 403, and a turntable 407 is arranged at the bottom end of the rotating shaft 405 and passing through the cover plate 3; two groups of baffles 408 are arranged at the bottom end of the cover plate 3, and a slide groove 409 is opened on one side of the baffle 408. A sliding block 410 is arranged inside the groove 409, and a rotating shaft 411 is arranged at the top of the sliding block 410; two groups of arc grooves 412 are opened at the bottom end of the turntable 407, and the rotating shaft 411 is connected to the arc groove 412, and a limiting ring 413 is arranged at the bottom end of the sliding block 410, so that by setting multiple groups of limiting rings 413, the cables placed inside the tray bridge 1 can be fixed, so as to achieve the purpose of limiting and fixing, avoid the phenomenon of internal cables being scattered, achieve a better cable tidying effect, prevent the cable from being displaced or slipped due to vibration or external force, thereby reducing the damage to the cable sheath caused by movement or friction, extending the service life of the cable, and reducing the failure and maintenance cost caused by cable damage.

[0031] The working principle of the cable limiting assembly 4 is as follows: after the cable is placed inside the tray bridge 1, the staff drives the worm 403 to rotate by manually turning the knob 404. During the rotation, the worm wheel 406 that matches it on one side follows the rotation, thereby driving the turntable 407 at the bottom end of the worm wheel 406 to rotate. When the turntable 407 rotates, the two groups of rotating shafts 411 slide inside the arc groove 412, thereby realizing the movement of the sliding block 410 at its bottom inside the sliding groove 409. During the movement, the distance between the two groups of sliding blocks 410 is changed. The staff can adjust the distance according to the size of the cable, and clamp the cable into the limit ring 413 to fix it, so as to prevent the cable from shifting or slipping due to vibration or external force.

[0032] In one embodiment, for the above-mentioned auxiliary component 5, the auxiliary component 5 includes a cold air fan 501 installed on one side of the tray bridge 1, and an air outlet 502 is provided on one side of the cold air fan 501.

Specifically, an installation groove that matches the air outlet duct 502 and the air outlet 503 is provided inside the tray bridge 1, so that when the cable generates excessive heat during operation, the air outlet 503 is utilized to reduce the temperature inside the tray bridge 1, reduce the increase in the cable temperature, and thereby protect the cable from overheating damage, ensuring that the working environment of the cable maintains a suitable working temperature.

[0033] The working principle of the auxiliary component 5 is as follows: the staff starts the air cooler 501 through an external controller, and then the external cold air is passed into the interior of the air outlet 502 under the action of the air cooler 501, and finally flows out from the air outlet 503. The specific arrangement direction of the air outlet 503 is two groups, upper and lower, and its purpose is to ensure that cold air is simultaneously passed to the top and bottom of the pallet bridge 1 to avoid excessive internal temperature.

[0034] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0035] In actual application, the staff installs the tray bridge 1 at the designated location and places the cable inside it. After the placement is completed, the cable is limited and fixed by the cable limiting component 4 to prevent the cable from becoming scattered during work. It can also prevent the cable from shifting or slipping due to vibration or external force, thereby reducing the damage to the cable sheath caused by movement or friction. After the placement is completed, the cover plate 3 and the tray bridge 1 are clamped together by the clamping component 2 to protect the internal cables.

[0036] After the installation is completed, the cable starts to work normally. After working for a long time, excessive heat may be generated inside the tray bridge 1. In order to prevent the cable from being damaged by overheating, the auxiliary component 5 is turned on to dissipate heat inside the tray bridge 1 to ensure that the working environment of the cable maintains a suitable working temperature.

[0037] In summary, with the aid of the above technical solutions of the utility model, the utility model has a simple structure and is easy to operate. By setting the snap-in assembly 2, the assembly between the tray bridge 1 and the cover plate 3 can be made faster and easier through the snap-in block 204 and the snap-in groove 203, ensuring that the two can be easily snapped together without a lot of installation work, and it is convenient to remove the cover plate 3 to inspect the cables inside the tray bridge 1 after long-term use. The utility model sets a cable limit assembly 4 so that the cables placed inside the tray bridge 1 can be fixed by setting multiple groups of limit rings 413, thereby achieving the purpose of limit fixation, avoiding the phenomenon of the internal cables being scattered, achieving a better cable tidying effect, preventing the cables from being displaced or slipped due to vibration or external force, thereby reducing the damage to the cable sheath caused by movement or friction, extending the service life of the cable, and reducing the failure and maintenance costs caused by cable damage. The utility model provides an auxiliary component 5 so that when the cable generates excessive heat during operation, the air outlet 503 is used to reduce the temperature inside the tray bridge 1, reduce the increase in cable temperature, and thus protect the cable from overheating damage, ensuring that the working environment of the cable maintains a suitable working temperature.
