Description

Technical Field

[0001] The utility model relates to the technical field of cable bridges, in particular to a vertical curved cable bridge. Background Art

[0002] A vertical bend cable tray is a type of cable tray component designed to change the direction of a cable routing path. It is primarily used for vertical bends in cable trays, such as those required for installation inside buildings or along walls.

[0003] When placing cables in a cable tray, for cables with a large number or large cross-sections, the curved parts will take up a larger space when placed in a bent cable tray than when placed in a straight cable tray. Although the existing bent cable tray is provided with an arc chamfer at the turning point, the space size of the bent cable tray at the turning point is still fixed and cannot be adjusted, which is not suitable for cables with a large number or large cross-sections; and for cables with a smaller cross-section, the bending curvature is smaller, which will make a large part of the space above the turning point unusable. Utility Model Content

[0004] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a vertical bent cable tray.

[0005] The technical solution of this utility model is as follows:

[0006] A vertical curved cable tray comprises a vertical curved body, a curved wire-releasing groove is provided in the middle of the vertical curved body, an adjustment opening is provided on the bottom surface of the curved wire-releasing groove at the bend, a curved support plate is detachably provided in the adjustment opening, and the height position of the curved support plate at the adjustment opening is adjustable;

[0007] A supporting plate located in the arc-shaped wire-releasing groove is provided above the arc-shaped support plate. The supporting plate is detachably connected to the arc-shaped support plate through a connecting rod. The upper end surface of the supporting plate is consistent with the curvature of the arc-shaped wire-releasing groove, and the width of the supporting plate is smaller than the width of the arc-shaped wire-releasing groove.

[0008] In normal state, the upper end surface of the arc-shaped support plate is flush with the bottom surface of the arc-shaped wire trough. When there are a large number of cables and they occupy a large space, the arc-shaped support plate is adjusted downward to disengage from the adjustment port. This can not only increase the space of the arc-shaped wire trough, but also dissipate heat for the cables at the corners of the vertical bend body. In addition, the space above the interior of the arc-shaped wire trough can be better utilized through the support plate.

[0009] The structure of the above-mentioned arc-shaped support plate that can be adjusted up and down is that a rib plate is provided on the bottom surface of the vertical bending body, and the rib plate is connected to the arc-shaped support plate through an adjusting rod. One end of the adjusting rod is threadedly connected to the rib plate, and the other end is rotatably connected to the arc-shaped support plate.

[0010] In order to facilitate the placement of different types of cables on the arc-shaped cable trough and the support plate, the distance between the lower surface of the support plate and the bottom surface of the arc-shaped cable trough is adjustable, and the distance between the lower surface of the support plate and the bottom surface of the arc-shaped cable trough can be adjusted according to the type of cable.

[0011] The structure with adjustable distance between the supporting plate and the arc-shaped wire-releasing groove is that the lower end of the connecting rod is threadedly connected to the arc-shaped supporting plate, and the upper end is rotatably connected to the supporting plate.

[0012] In order to prevent the cables placed on the pallet from falling off the pallet and causing disordered distribution of the cables, guard plates are provided on both sides of the pallet along the width direction to block the cables on the pallet.

[0013] In order to facilitate the placement of a larger number of cables on the support plate, the opposite side surfaces of the two guard plates are inclined surfaces inclined outwards, thereby increasing the load-bearing capacity of the support plate.

[0014] Regarding the height of the support plate in the vertical bend body, the vertical distance between the lower surface of the support plate and the bottom surface of the arc-shaped wire-laying trough is 3-10cm, which is convenient for placing 0.75mm between the bottom surface of the arc-shaped wire-laying trough and the support plate. 2 -10mm 2 Cables of different cross-sections.

[0015] To prevent the width of the pallet from affecting the placement of several cables in the arc-shaped cable trough, the ratio of the width of the pallet to the width of the arc-shaped cable trough is 0.3-0.5, so that the cables can be placed on both sides of the pallet without affecting the stacking thickness of several cables.

[0016] In order to facilitate the limiting and separation of the cables between the bottom of the support plate and the arc-shaped cable trough and avoid the cables from being entangled, multiple cable separators are provided along the arc direction of the lower surface of the support plate, and the multiple cable separators are arranged at intervals.

[0017] Regarding the structure of the cable separator, the height of the cable separator is 0-3cm, which can be 0.75mm 2 -10mm 2 Separate and limit cables with different cross-sections.

[0018] The beneficial effects of the present invention are:

[0019] An arc-shaped support plate that can be adjusted up and down is provided so that it can be moved downward to disengage from the adjustment port. This allows adjustment when there are a large number of cables and a large space is occupied at the bend of the vertical bend body, thereby preventing the cables from being entangled or squeezed at the bend, which is not conducive to the replacement or maintenance of the cables in the later stage. The adjustable arc-shaped support plate can not only enlarge the space of the arc-shaped cable trough, but also play a heat dissipation role for the cables at the corners of the vertical bend body.

[0020] The support plate can not only make better use of the space above the arc-shaped cable trough, but also can place cables with larger cross-sections or larger curvatures when bent, so that cables with different cross-sections can be arranged in categories, which is convenient for later replacement and maintenance.

[0021] In order to facilitate the placement of cables of different types on the arc-shaped cable trough and the support plate, the distance between the lower surface of the support plate and the bottom surface of the arc-shaped cable trough is adjustable. The distance between the lower surface of the support plate and the bottom surface of the arc-shaped cable trough can be adjusted according to the type of cable;

[0022] In order to facilitate the limiting and separation of the cables between the bottom of the support plate and the arc-shaped cable trough and avoid the cables from being entangled, a plurality of cable separators are provided along the arc direction of the lower surface of the support plate. The plurality of cable separators are arranged at intervals. When it is necessary to limit the cables under the support plate, the connecting rod is adjusted to move the support plate toward the bottom surface of the arc-shaped cable trough, thereby pressing down the cables and preventing them from loosening.
