Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, and specifically to a combined aluminum alloy cable tray. Background Technology

[0002] Cable trays are classified into various structures such as trough-type cable trays, tray-type cable trays, ladder-type cable trays, and mesh cable trays. They consist of supports, brackets, and installation accessories. They can be installed independently or laid on various buildings and pipe rack supports. They feature simple structure, beautiful appearance, flexible configuration, and convenient maintenance. All parts must be galvanized. For cable trays installed outdoors, especially in areas near the sea or in corrosive regions, the material must have properties such as corrosion resistance, moisture resistance, good adhesion, and high impact resistance.

[0003] Most existing cable trays are fixed frame structures, with only the cover plate being removable from the cable tray. The support plates and side plates are fixedly connected. This means that the hollow part of the cable tray also requires a large amount of transport space when transporting the cable tray, which indirectly increases the transportation cost and reduces its applicability. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing a modular aluminum alloy cable tray. This solves the problem that most existing cable trays are fixed frame structures, with only the cover plate being detachable from the cable tray, while the support plates and side plates are fixedly connected. This results in the hollow part of the cable tray occupying a large amount of transportation space, indirectly increasing transportation costs and reducing applicability.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A modular aluminum alloy cable tray includes a tray body, which includes a supporting base plate. The supporting base plate has symmetrically detachable connecting side plates on both sides. The bottom sides of the connecting side plates have symmetrically arranged snap-fit ​​plates. The top surface of each snap-fit ​​plate has multiple evenly distributed fastening posts. Both sides of the connecting side plates have multiple first connecting holes for connecting bolts to be inserted. The two ends of the connecting side plates have symmetrically arranged receiving grooves communicating with the first connecting holes. An extension side plate slides within the receiving groove. The bottom surface of the extension side plate has a guide plate. A second connecting hole, through which the extension side plate is received within the receiving groove and communicating with the first connecting hole, is opened on the extension side plate. A third connecting hole, through which the extension side plate slides out of the receiving groove and communicating with the first connecting hole, is opened on the extension side plate on one side of the second connecting hole. A cover plate is detachably provided between the tops of the two connecting side plates.

[0007] As a preferred technical solution of this utility model, the supporting base plate has through mounting grooves on both sides for connecting side plates to pass through. The bottom end face of the supporting base plate on both sides of the mounting groove is provided with a snap-fit ​​groove that matches the snap-fit ​​plate. The snap-fit ​​groove is provided with a fastening groove that corresponds to the fastening post.

[0008] The above technical solution improves the connection strength between the connecting side plate and the bearing base plate by using the snap-fit ​​plate and snap-fit ​​groove. Furthermore, the connection strength between the connecting side plate and the bearing base plate is further improved by using the fastening groove and fastening post.

[0009] As a preferred technical solution of this utility model, a guide groove for displacement of the guide plate is provided on the top end face of the bearing base plate at both ends of the mounting groove, and the guide groove is connected to the mounting groove.

[0010] The above technical solution improves the connection strength between the extended side plate and the load-bearing base plate by using the guide groove and guide plate.

[0011] As a preferred technical solution of this utility model, multiple guide plates are symmetrically arranged on both sides of the extended side plate, and guide grooves that fit with the guide plates are opened on both inner side walls of the receiving groove.

[0012] The above technical solution improves the connection strength between the extension side plate and the connecting side plate by using the guide groove and guide plate.

[0013] As a preferred technical solution of this utility model, a first fixing hole for inserting fixing bolts is provided on the top end face of the extended side plate, and a second fixing hole communicating with the first fixing hole is provided through the cover plate.

[0014] By using the above technical solution, the stability of the cover plate installation is improved by using the first fixing hole, the second fixing hole and the fixing bolt, thus preventing the cover plate from being easily opened.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention allows for complete separation of the two connecting side plates from the supporting base plate during transportation, avoiding the space occupation and increased transportation costs associated with fixed frame-shaped cable trays. When assembling the cable tray body, firstly, one end of the connecting side plate is inserted through the supporting base plate, allowing the snap-fit ​​plate on the connecting side plate to snap into the snap-fit ​​groove on the supporting base plate. The fastening post on the snap-fit ​​plate is then inserted into the fastening groove within the snap-fit ​​groove, thus initially fixing the connecting side plate to the supporting base plate. Next, the extended side plate within the receiving groove of the connecting side plate is slid, allowing the guide plate at the bottom of the extended side plate to insert into the guide groove on the supporting base plate, thereby improving the connection strength between the connecting side plate and the supporting base plate. Connecting bolts are then inserted into the first connecting hole on the connecting side plate and the third connecting hole on the extended side plate for fixation. Finally, a cover plate is installed between the tops of the two connecting side plates, connecting the second fixing hole on the cover plate with the first fixing hole on the extended side plate. Fixing bolts are then inserted into the connected first and second fixing holes for fixation, completing the assembly and installation of the cable tray body. Attached Figure Description
