Description

Technical Field

[0001] This utility model relates to the technical field of aluminum alloy cable trays that are easy to hoist, and particularly to an aluminum alloy cable tray that is easy to hoist. Background Technology

[0002] Aluminum alloy cable trays are extruded from aluminum alloy, resulting in high dimensional accuracy, good strength, beautiful appearance, light weight, and large load-bearing capacity. The surface of the aluminum alloy cable tray is sandblasted and oxidized to form a natural protective oxide film, which has strong corrosion resistance to the atmosphere and chemical media. Aluminum alloy cable trays are simple in structure, novel in design, have a large load capacity, are lightweight, corrosion-resistant, have a long service life, are easy to install, and are suitable for general environments. In coastal areas with fog, high humidity, and corrosive environments, the unique corrosion resistance of aluminum alloy cable trays is even more evident.

[0003] In existing technologies, aluminum alloy cable trays are mostly installed on the roof by using screw rods. The installation method of cable trays is often simple in structure, lacks flexibility and adjustment and has limited stability. It is difficult to efficiently adapt to different specifications of aluminum alloy cable trays and ensure stable installation. Therefore, we propose an aluminum alloy cable tray that is easy to install. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0023] Please see the appendix Figure 1 - Appendix Figure 6An aluminum alloy cable tray for easy hoisting includes a frame 1 and a hoisting mechanism 5. The hoisting mechanism 5 includes a load-bearing frame 501. The load-bearing frame 501 is connected to two sets of threaded grooves 503 via threaded rods 502. Both sets of threaded grooves 503 are connected to connectors 509 via lower hoisting frames 504 and connector slots 506. The connectors 509 are connected to fixing bolts 508 via upper hoisting frames 507. A first threaded rod mounting bracket 505 is fixedly installed on the side of the lower hoisting frame 504 away from the frame 1. A cover plate 2 is slidably connected to the upper end of the frame 1. Threaded holes 3 are opened on the upper surface of the cover plate 2. Connectors 4 are fixedly installed on both sides of the frame 1. The upper end of the upper part abuts against the bottom of the frame 1. Two sets of lower lifting frames 504 abut against the sides of the frame 1 respectively. The threaded rod 502 is threadedly connected to two sets of threaded grooves 503. The lower lifting frame 504 is fixedly installed on the upper end of the threaded groove 503. The insertion groove 506 is opened inside the lower lifting frame 504 near the upper end. The upper lifting frame 507 is fixedly installed on the upper end of the insertion piece 509. The size of the insertion piece 509 is adapted to the insertion groove 506. One end of the insertion piece 509 is the same size as the connector 4, and its internal thread is connected with a fastening bolt 510. The threaded hole 3 passes through the upper lifting frame 507, and the internal thread of the threaded hole 3 is connected with a fixing bolt 508.

[0024] One end of the plug-in 509 is the same size and shape as the connector 4, so that the lower lifting frame 504 can be connected to the frame 1 by the fastening bolt 510, which facilitates the positioning and installation of the lower lifting frame 504. At the same time, the upper lifting frame 507 has a hole that is the same as the threaded hole 3, so that the upper lifting frame 507 can be connected to the cover plate 2 by the fixing bolt 508, which facilitates the positioning and installation of the upper lifting frame 507. When the cover plate 2 is slidably connected to the frame 1, it connects the upper lifting frame 507 and the lower lifting frame 504.

[0025] Specifically, the spacing between the two sets of lower hanging frames 504 can be changed by rotating the threaded rod 502 to adapt to aluminum alloy cable trays of different widths. The upper hanging frame 507 is fixed to the cover plate 2 by fixing bolts 508. Then, the plug-in piece 509 on the upper hanging frame 507 is inserted into the plug-in slot 506 of the lower hanging frame 504. When the cover plate 2 is placed on the frame 1, the upper hanging frame 507 and the lower hanging frame 504 are connected and tightened in the plug-in piece 509 and the connector 4 by fastening bolts 510, so that the upper hanging frame 507 and the lower hanging frame 504 are fixed. Then, the entire aluminum alloy cable tray is hoisted to the roof by the first threaded rod mounting bracket 505 through the threaded rod and nut. Compared with the traditional method of hoisting by only using threaded rod, it is more stable and has a wider range of applications. Example 2

[0026] Please see the appendix Figure 1 and attached Figure 7Furthermore, based on Embodiment 1, a connecting mechanism 6 is provided at one end of the frame 1 and the cover plate 2. The connecting mechanism 6 includes two sets of first connecting frames 601, two sets of second connecting frames 604, a first strong spring 603, and a second strong spring 605. A second screw mounting bracket 602 is fixedly installed on the outer side of both sets of first connecting frames 601 and two sets of second connecting frames 604. Mounting grooves 606 are opened at both ends of both sets of first connecting frames 601 and two sets of second connecting frames 604. The ends of the first strong spring 603 and the second strong spring 605 are fixedly installed in the mounting grooves 606. The first connecting frames 601 and the second connecting frames 604 are connected by the first strong spring 603, and the two sets of first connecting frames 601 and the two sets of second connecting frames 604 are connected by the second strong spring 605.

[0027] A first strong spring 603 is fixedly installed in the mounting groove 606 at one end of each pair of the two sets of first connecting brackets 601 and the two sets of second connecting brackets 604, and a second strong spring 605 is fixedly installed at the other end, so that the two sets of first connecting brackets 601 and the two sets of second connecting brackets 604 can form rectangles of different sizes to adapt to aluminum alloy cable trays of different sizes.

[0028] Specifically, by using two sets of first connecting brackets 601 and two sets of second connecting brackets 604, along with a first strong spring 603 and a second strong spring 605, the size of the rectangle formed by the two sets of first connecting brackets 601 and two sets of second connecting brackets 604 can be changed within a certain range, thereby adapting to aluminum alloy cable trays of different sizes. At the same time, a second screw mounting bracket 602 is provided, which makes it convenient and quick to connect aluminum alloy cable trays and increases the stability of the connection.

[0029] The working principle of this utility model is as follows: This utility model is an aluminum alloy cable tray that is easy to hoist. First, align the hole on the upper hoisting bracket 507 with the threaded hole 3 on the cover plate 2, then tighten the fixing bolt 508 into the threaded hole 3. Next, rotate the threaded rod 502 to separate the two sets of lower hoisting brackets 504. Place the frame 1 on the load-bearing frame 501, then adjust the two sets of lower hoisting brackets 504 to abut against the frame 1. Then, pass the lead screw through the first lead screw mounting bracket 505 and install it on the roof. Tighten the nut and place the aluminum alloy cable tray on the roof. After the cable tray frame 1 is fixed and the cable is laid, the cover plate 2 is placed on the frame 1, so that the connector 509 of the upper hoisting frame 507 is inserted into the connector slot 506, and the fastening bolt 510 is tightened inside the connector 509 and the connector 4 to realize the installation and fixation of the cover plate 2. When connecting adjacent frames 1, one end of the adjacent frames 1 is joined together, and then the two sets of first connecting frames 601 and two sets of second connecting frames 604 are separated in pairs to form a rectangle, which is then placed on the outside of the connection of the two sets of frames 1 to achieve stable connection.
