Description

Technical Field

[0001] This application relates to the technical field of cable trays, and in particular to a high-strength molded cable tray. Background Technology

[0002] Cable trays include trough-type cable trays, tray-type cable trays, ladder-type cable trays, and mesh cable trays. They can be installed independently or attached to various buildings and pipe rack supports for laying cables.

[0003] Cable trays are trough-shaped components made from a single sheet of steel and used to place cables. When cables are laid inside the cable tray, most of the weight of the cable tray is concentrated on the base plate of the tray. Traditional cable tray base plates are mostly flat, with poor structural strength, which can lead to situations where the cable tray deforms before the building is completed. Utility Model Content

[0004] In order to improve the structural strength and service life of cable trays, this application provides a high-strength molded cable tray.

[0005] The high-strength molded cable tray provided in this application adopts the following technical solution:

[0006] A high-strength molded cable tray includes a base plate and two side plates. One end of each side plate is connected to one end of the base plate. The side plates are perpendicular to the base plate. A plurality of reinforcing structures are distributed at intervals on the side of the base plate near the side plates. Each reinforcing structure includes a plurality of protrusions protruding toward the side of the base plate near the side plates. The protrusions in the same group are evenly distributed, and a groove is provided between two adjacent protrusions in the same group.

[0007] By adopting the above technical solution, the base plate is provided with several reinforcing structures. Each reinforcing structure is provided with alternating protrusions and grooves, which reduces stress concentration on the base plate, improves the structural strength of the base plate, and thus improves the structural strength of the cable tray and extends the service life of the cable tray.

[0008] Preferably, the base plate and the side plate are integrally stamped, and the thickness of the base plate and the side plate is equal at all points.

[0009] By adopting the above technical solution, the base plate and side plate are integrally stamped, which improves the overall structural strength of the cable tray; the thickness of the base plate and side plate is equal in all places, which reduces the local stress concentration of the cable tray and improves the service life of the cable tray.

[0010] Preferably, the bottom plate is provided with a plurality of protruding rings on the side near the side plate. The number of protruding rings is the same as the number of reinforcing structures and corresponds one-to-one. The protruding rings surround the reinforcing structures, and the thickness of the protruding rings is equal to the thickness of the bottom plate.

[0011] By adopting the above technical solution, a reinforced structure is set with convex rings, the number of convex rings being the same as the number of reinforced structures and corresponding one-to-one, which reduces the phenomenon of local stress concentration in the base plate and improves the structural strength of the base plate.

[0012] Preferably, the side plate is provided with a plurality of longitudinal reinforcing ribs, the longitudinal reinforcing ribs extending along the length direction of the side plate, the plurality of longitudinal reinforcing ribs being spaced apart along the width direction of the side plate, and the thickness of the longitudinal reinforcing ribs being equal to the thickness of the side plate.

[0013] By adopting the above technical solution, longitudinal reinforcing ribs are provided on the side plate. The longitudinal reinforcing ribs extend along the length of the side plate, which improves the bending resistance of the side plate, reduces the possibility of the cable tray being bent and damaged by external forces, and improves the service life of the cable tray.

[0014] Preferably, the longitudinal stiffener has an arc-shaped cross-section.

[0015] By adopting the above technical solution, the longitudinal stiffener has an arc-shaped cross section, which helps to disperse the stress on the side plate as a whole, reduce the possibility of stress concentration, and improve the service life of the cable tray.

[0016] Preferably, a plurality of side reinforcing ribs are provided between two adjacent longitudinal reinforcing ribs, and the plurality of side reinforcing ribs are distributed at intervals along the length direction of the longitudinal reinforcing ribs.

[0017] By adopting the above technical solution, side reinforcing ribs are set on the side plate, and the side reinforcing ribs are distributed at intervals along the length of the side plate, which reduces the possibility of stress concentration on the electrical side plate and improves the service life of the cable tray.

[0018] Preferably, the base plate is provided with a plurality of spaced heat dissipation grooves, the thickness of the heat dissipation grooves is equal to the thickness of the base plate, and there is at least one heat dissipation groove between two adjacent reinforcing structures.

[0019] By adopting the above technical solution and setting heat dissipation grooves, the heat dissipation area between the base plate and the outside is increased, which facilitates the transfer of heat generated by the cables inside the cable tray to the outside of the cable tray, thereby improving the service life of the cable tray.

[0020] Preferably, the bottom of the heat dissipation groove has a plurality of through holes evenly distributed thereon.

[0021] By adopting the above technical solution and setting through holes, it is easy for the air inside the cable tray to communicate with the outside, so as to facilitate the direct exchange of hot and cold air, realize air flow, and enhance the heat dissipation effect.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The base plate is equipped with several reinforcing structures, each consisting of alternating protrusions and grooves, which reduces stress concentration on the base plate, improves the structural strength of the base plate, and consequently improves the structural strength and service life of the cable tray.

[0024] 2. The reinforcing structure is surrounded by convex rings, with the number of convex rings matching the number of reinforcing structures, which reduces local stress concentration in the base plate and improves the structural strength of the base plate.

[0025] 3. The side plate is equipped with longitudinal stiffeners that extend along the length of the side plate, improving the bending resistance of the side plate and reducing the possibility of the cable tray being bent and damaged by external forces. The longitudinal stiffeners have an arc-shaped cross-section, which helps to distribute the stress on the side plate as a whole, reducing the possibility of stress concentration and improving the service life of the cable tray.
