Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, and in particular to a high-strength aluminum alloy cable tray. Background Technology

[0002] During cable tray installation, connections between cable trays typically require the use of cable tray connecting plates. Existing connections between these plates and the cable trays are made by welding or, in some cases, by threading. Welding can lead to incomplete welds, resulting in a weak connection. Furthermore, the welded areas are prone to corrosion after welding, which can cause the cable tray to detach from the connecting plate, shift, or loosen, resulting in poor connection effectiveness and low connection strength. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by providing a high-strength aluminum alloy cable tray, thereby solving the problem that the connection between existing cable trays is prone to displacement or loosening, resulting in poor connection effect and low connection strength.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A high-strength aluminum alloy cable tray includes a cable tray body. A support frame is provided on the outer side of one end of the cable tray body. A support frame with a U-shaped structure is slidably connected inside the support frame. Multiple first mounting holes for fixing bolts are opened on both the upper and lower sides of one end of the support frame. A bearing seat is symmetrically provided on both sides of the bottom of the other end of the cable tray body. The bearing seat has a bearing groove that allows the support frame to be inserted after displacement. A connecting plate is fixedly connected to the outer wall of the cable tray body at the top of the bearing seat. Both the connecting plate and the bearing seat have first fixing holes that allow the support frame to be inserted into the bearing groove and communicate with the first mounting holes.

[0006] As a preferred technical solution of this utility model, a reinforcing frame with a U-shaped structure is slidably connected to the inner side wall of the cable tray body near the support frame. The top two sides of the reinforcing frame are symmetrically provided with connecting plates that extend into the support frame and are connected to the support frame.

[0007] As a preferred technical solution of this utility model, multiple reinforcing strips are evenly distributed on the inner sidewalls at both ends of the cable tray body, and reinforcing grooves adapted to the reinforcing strips are provided on the outer sidewall of the reinforcing frame.

[0009] As a preferred technical solution of this utility model, the support frame is provided with drive handles symmetrically on both sides, and the support frame is provided with a limiting groove that can limit the forward and backward displacement of the drive handles.

[0010] As a preferred technical solution of this utility model, the upper and lower sides of the support frame are provided with support frames housed in the support frame and second fixing holes that are connected to the first mounting holes one by one.

[0011] As a preferred technical solution of this utility model, the support frame has second mounting holes on the upper and lower sides of the middle part, which are connected to the support frame and the second fixing holes.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0021] Example

[0022] refer to Figures 1-4 A high-strength aluminum alloy cable tray includes a cable tray body 1. A support frame 101 is provided on the outer side of one end of the cable tray body 1. A support frame 102 with a U-shaped structure is slidably connected inside the support frame 101. The support frame 102 provides effective support at the connection between the two cable tray bodies 1, improving the strength of the connection. Multiple first mounting holes 103 for inserting fixing bolts 2 are provided on both the upper and lower sides of one end of the support frame 102. Bearing seats 104 are symmetrically provided on both sides of the bottom of the other end of the cable tray body 1. Bearing grooves 105 are provided on the bearing seats 104 to allow the support frame 101 to be inserted after displacement. A connecting plate 106 is fixedly connected to the outer wall of the cable tray body 1 at the top of the bearing seat 104. Both the connecting plate 106 and the bearing seat 104 have first fixing holes 107 that connect the support frame 102 to the bearing groove 105 and communicate with the first mounting holes 103.

[0023] Furthermore, a reinforcing frame 108 with a U-shaped structure is slidably connected to the inner side wall of the cable tray body 1 near the support frame 101. The top two sides of the reinforcing frame 108 are symmetrically provided with connecting plates 109, one end of which extends into the support frame 101 and is fixedly connected to the support frame 102.

[0024] Furthermore, both sides of the support frame 101 are provided with connecting grooves 112 for the connecting plate 109 to move back and forth.

[0025] In a further optimized design, multiple reinforcing strips 110 with triangular or trapezoidal cross-sections are evenly distributed on the inner sidewalls at both ends of the cable tray body 1. A reinforcing groove 111 adapted to the reinforcing strips 110 is provided on the outer sidewall of the reinforcing frame 108. The arrangement of the reinforcing groove 111 and the reinforcing strips 110 increases the tightness of the connection between the two cable tray bodies 1 and further improves the connection strength between them.

[0026] Furthermore, the support frame 102 is symmetrically provided with drive handles 113 on both sides. The drive handles 113 facilitate the operation of the support frame 102 by the staff. The support frame 101 is provided with a limiting groove 114 that can limit the forward and backward displacement of the drive handle 113. The limiting groove 114 and the drive handle 113 cooperate to limit the displacement of the support frame 102.

[0027] Furthermore, the support frame 101 has support brackets 102 on its upper and lower sides, which are housed in the support frame 101 and connected to the first mounting holes 103 in a series of second fixing holes 115. When the cable tray body 1 is not installed or used, the support brackets 102 are housed in the support frame 101, which is aesthetically pleasing and simple. The support brackets 102 are fixed by inserting fixing bolts 2 into the second fixing holes 115 and the first mounting holes 103.

[0028] Furthermore, the support frame 102 has second mounting holes 116 on its upper and lower sides at the middle, which are connected to the bearing groove 105 and the second fixing hole 115. When the cable tray body 1 is installed and used, the front part of the support frame 102 is inserted into the bearing groove 105 on the adjacent cable tray body 1, and is fixed by inserting the fixing bolts 2 into the first fixing hole 107 and the first mounting hole 103 and the second fixing hole 115 and the second mounting hole 116, so that the two adjacent cable tray bodies 1 are stably connected.

[0029] It should be noted that the first fixing hole 107, the second fixing hole 115, the first mounting hole 103 and the second mounting hole 116 are all internal threaded holes of the same size, which facilitates threaded connection with the fixing bolt 2, thereby facilitating the installation and disassembly of the cable tray body 1 by the staff.

[0030] It should be noted that after the two adjacent cable tray bodies 1 are connected, the two ends of the support frame 102 and the reinforcing frame 108 are symmetrical along the connection point of the two cable tray bodies 1. The length of the support frame 102 and the reinforcing frame 108 on each cable tray body 1 is half the length of the support frame 102 and the reinforcing frame 108, so that the connection point of the two cable tray bodies 1 can be balanced and stable.

[0031] The working principle of this utility model:

[0032] During installation, workers assemble the two adjacent cable tray bodies 1 end to end, push the drive handle 113 to drive the front part of the support frame 102 to insert into the bearing groove 105 on the adjacent cable tray body 1, and at the same time, the front part of the reinforcing frame 108 also moves into the inner cavity of the adjacent cable tray body 1, so that the reinforcing strip 110 on the adjacent cable tray body 1 is inserted into the reinforcing groove 111 on the reinforcing frame 108. At this time, the first mounting hole 103 on the support frame 102 is connected to the first fixing hole 107 on the cable tray body 1, and the second mounting hole 107 on the support frame 102 is connected to the first fixing hole 107 on the cable tray body 1. The mounting holes 116 are connected one by one with the second fixing holes 115 on the cable tray body 1. The fixing bolts 2 are inserted into the first fixing hole 107 and the first mounting hole 103 and the second fixing hole 115 and the second mounting hole 116 in sequence for fixing, thereby completing the installation of the two adjacent cable tray bodies 1. This improves the connection strength of the inner and outer sides of the connection between the two connected cable tray bodies 1, avoids displacement or loosening during use, and improves the stability and firmness between the two connected cable tray bodies 1, making it safer and more reliable to use.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
