Description

Technical Field

[0001] The present invention relates to the technical field of cable bridges, in particular to a cable bridge with a slide groove. Background Art

[0002] Cable trays are divided into trough type, tray type, ladder type, grid type and other structures. They are composed of brackets, supports and installation accessories. They are mainly used to support and protect cables. Cable trays need to be fixed in appropriate positions through cable brackets when in use.

[0003] The existing cable tray is mainly composed of a main beam, connecting parts, supporting parts and a sliding cover. When laying the cable tray suspended on the top, the opening direction of the cable tray is generally facing upward (if the opening is facing downward, it is not convenient to lay the cables, and secondly, it cannot support the cables well. If it is opened on the side, secondly, since some of the interior of the cable tray does not have a mechanism to fix the position of the cables, it will cause the gap between the cables to be difficult to control when laying the cables. If it has a position fixing mechanism, it will cause high installation difficulty during the side installation process). That is, the opening direction is opposite to the top direction, which results in a gap being required between the cable tray and the top, and when multiple cables are placed together, the cables will generate heat in a concentrated manner. The existing cable tray is subject to its own performance requirements, which results in it being able to only open through holes on its main beams for heat dissipation in order to ensure the heat dissipation effect. This results in a relatively fixed ventilation effect and the heat dissipation effect cannot be guaranteed. Summary of the Invention

[0004] The technical solution of the present invention addresses the technical problem that the existing technical solutions are too single, and provides a solution that is significantly different from the existing technology. An embodiment of the present invention provides a cable tray with a slide groove to solve the technical problem that the existing cable tray is inconvenient to place cables into the cable tray due to the opening direction.

[0005] An embodiment of the present invention adopts the following technical solution: a cable tray with a slide groove, which also includes a tray shell, a protective mechanism for wrapping the tray shell, and a driving mechanism for driving the protective mechanism to automatically open. Matching guide grooves are provided at both ends of the tray shell, and a card block for fixing the cable is provided in the tray shell, and a temperature sensor is provided in the tray shell.

[0006] Furthermore, the cross section of the bridge frame shell is U-shaped.

[0007] Furthermore, the protection mechanism includes a mating protective shell, which is located in the bridge frame shell. A guide shaft is rotatably arranged in the mating protective shell, a winding elastic plate is arranged in the mating protective shell, and the mating protective shell is slidably connected to the end of the winding elastic plate.

[0008] Furthermore, the cross section of the mating protective shell is L-shaped.

[0009] Furthermore, a return spring is provided in the connecting slide groove between the winding spring plate and the matching protective shell.

[0010] Furthermore, the driving mechanism includes a rotating shaft tooth and a floating rack, the floating rack is located in a mating guide groove, and a connecting spring is provided between the floating rack and the mating guide groove, a mating block is provided at one end of the floating rack, a resistance block is provided above the mating block, an electric telescopic rod is provided above the resistance block, and a connecting shaft tooth is provided next to the resistance block.

[0011] Furthermore, in the initial state, the rotating shaft teeth and the connecting shaft teeth are staggered, and the rotating shaft teeth are engaged with the floating rack.

[0012] Furthermore, the matching block and the floating rack contact block are in oblique contact, and the interference block and the matching block are in oblique contact.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] First, the original integrated U-shaped protective shell is transformed into a split shell, thereby changing the existing upper opening method to a pull-type opening, thus avoiding the opening direction and the top direction being opposite, which results in the need to reserve a gap between the cable tray and the top. In the subsequent maintenance process, it is easier to expose the cables inside the cable tray shell, achieving the effect of facilitating maintenance;

[0015] At the same time, during use, the working mode is changed to a pull-out mode, and during the pulling process, the retracted elastic plate is automatically pulled apart, thereby automatically opening the opening. At this time, the actual opening is changed to an L-shaped opening. Compared with the existing top opening, the L-shaped opening has a larger opening angle. The larger opening angle makes it easier to install. At the same time, more surface is exposed during maintenance, which makes the operating space larger.

[0016] During use, since there are often multiple cables in the cable tray, and the cables will also generate heat during use, the heat generated between the multiple cables is difficult to dissipate in the relatively sealed tray, resulting in increased cable transmission loss. For this reason, it is necessary to make the tray have a certain heat dissipation effect. At this time, the driving mechanism can automatically open the protective shell, thereby converting the relatively sealed tray into a semi-enclosed type, thereby improving the heat dissipation effect;

[0017] To sum up, the existing bridge structure is transformed from an integrated design to a split movable design, so that the bridge has a relatively wider operating space during installation and maintenance, thereby facilitating operation. Secondly, during use, the driving mechanism can assist in cooperating with the protective shell to achieve the effect of opening and closing, thereby improving the heat dissipation effect of the bridge.

[0032] The following combination Figures 1 to 6 As shown, an embodiment of the present invention provides a cable tray with a slide groove, which also includes a tray shell 1, a protection mechanism 3 for wrapping the tray shell 1, and a driving mechanism 2 for driving the protection mechanism 3 to automatically open. Matching guide grooves 12 are provided at both ends of the tray shell 1, and a clamping block 11 for fixing the cable is provided in the tray shell 1, and a temperature sensor is provided in the tray shell 1.

[0033] Specifically, the cross section of the bridge housing 1 is U-shaped.

[0034] Specifically, the protection mechanism 3 includes a mating protective shell 31, which is located in the bridge frame housing 1. A guide shaft 32 is rotatably arranged in the mating protective shell 31, a winding elastic plate 33 is arranged in the mating protective shell 31, and the mating protective shell 31 and the end of the winding elastic plate 33 are slidingly connected.

[0035] Specifically, the cross section of the mating protective shell 31 is L-shaped.

[0036] Specifically, a return spring is provided in the connecting slide groove between the winding spring plate and the matching protective shell 31 .

[0037] Specifically, the driving mechanism 2 includes a rotating shaft tooth 21 and a floating rack 26, the floating rack 26 is located in the mating guide groove 12, and a connecting spring is provided between the floating rack 26 and the mating guide groove 12, and a mating block 25 is provided at one end of the floating rack 26, and a resistance block 24 is provided above the mating block 25, and an electric telescopic rod 23 is provided above the resistance block 24, and a connecting shaft tooth 22 is provided next to the resistance block 24.

[0038] Specifically, in the initial state, the rotating shaft teeth 21 and the connecting shaft teeth 22 are staggered, and the rotating shaft teeth 21 are engaged with the floating rack 26 .

[0039] Specifically, the matching block 25 and the floating rack 26 contact each other in an oblique surface contact, and the contact block 24 and the matching block 25 contact each other in an oblique surface contact.

[0040] Working principle: When it is necessary to install the cable again, the matching protective shell 31 is pulled. At this time, there is no other source of heat in the bridge shell 1 because there is no cable installed. For this reason, the temperature angle in the bridge shell 1, the electric telescopic rod 23 does not work. At this time, the floating rack 26 is engaged with the rotating shaft teeth 21. When the matching protective shell 31 is pulled, the rotating shaft teeth 21 rotates, and the rotating matching protective shell 31 rewinds the rewinding elastic plate 33. At this time, due to the sliding connection between the rewinding elastic plate 33 and the matching protective shell 31, the rewinding elastic plate 33 is rewound along the matching protective shell 31, thereby completing the opening of one side thereof, and at the same time Since the matching protective shell 31 is drawn out from the bridge housing 1, the matching protective shell 31 itself has no sealing on the top, and the winding elastic plate 33 of the side wall is opened, so that there are two openings, which is convenient for the installation and subsequent maintenance of the cable. When the installation is completed, the matching protective shell 31 is pushed back to its original position, and the winding elastic plate 33 is also reset. Since there are often multiple cables in the cable bridge, and the cables will also generate heat during use, the heat generated between the multiple cables is difficult to dissipate in the relatively sealed bridge, which leads to increased transmission loss of the cable. When the temperature in the bridge housing 1 is too high, the cable will not be heated. After reaching a certain level, the temperature sensor located in the bridge housing 1 sends a signal to the electric telescopic rod 23, and the electric telescopic rod 23 works to push the resistance block 24 downward, and the resistance block 24 moves downward to resist the matching block 25, thereby causing the matching block 25 to be displaced. In the initial state, the matching block 25 contacts the end of the floating rack 26, providing a limiting effect for the floating rack 26. At this time, when the matching block 25 is displaced, resulting in no contact with the floating rack 26, the floating rack 26 is reset under the action of the reset spring below, and the floating rack 26 is disengaged from the rotating shaft teeth 21. At the same time, due to the resistance block 24 and the matching block 25 are in inclined contact. When the interference block 24 pushes the matching block 25 to move to a certain extent, the matching block 25 no longer moves, but the interference block 24 can still move. The total displacement of the interference block 24 is much larger than the movement stroke of the matching block 25. After the interference block 24 moves a certain distance, the connecting shaft teeth 22 on the matching block 25 contact the rotating shaft teeth 21, causing the rotating shaft teeth 21 to rotate passively, thereby achieving the effect of winding up the winding elastic plate 33. At this time, there is space for direct exchange between the bridge frame housing 1 and the outside world, thereby improving the heat dissipation effect of the bridge frame housing 1.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.

However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
