Description

Technical Field

[0001] This utility model relates to a cable tray support arm, and more particularly to a novel support arm for irregularly shaped cable trays. Background Technology

[0002] Cable tray support arm construction, in relatively flat work areas, mainly involves the installation of cable tray supports and cable tray brackets. After the cable tray supports and brackets are mass-produced in the factory, they are then installed manually.

[0003] When laying cable trays on uneven original excavation surfaces such as tunnels, the existing models of cable trays and brackets cannot meet the actual needs of the project due to the uneven installation surface. If cable tray brackets are processed on-site, it is time-consuming and labor-intensive, which affects the progress of the project and results in low efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a new type of cable tray support arm that is highly adaptable, stable and safe, easy to assemble and disassemble, and has high construction efficiency.

[0005] This utility model discloses a novel support arm for cable trays on irregular surfaces, comprising a fixing device, which is fixed to the irregular surface to form a support structure for the cable tray on the irregular surface; a support device, which is used to support and fix the cable tray; and a connecting device, which is used to connect the fixing device and the support device to form a strong and stable cable tray support structure.

[0006] This utility model discloses a novel support arm applicable to cable trays with irregular surfaces, wherein the fixing device includes a first anchor nail and a second anchor nail, the first anchor nail and the second anchor nail are firmly nailed in the vertical direction along the irregular surface and maintain a certain distance.

[0007] This utility model discloses a novel support arm suitable for irregular surface cable trays, wherein the support device includes a base and a fixing clamp, and the fixing clamp fixes the cable tray to the base by bolts.

[0008] This utility model discloses a novel support arm applicable to irregular cable trays, wherein the connecting device includes a horizontal telescopic rod and an inclined telescopic rod. One end of the horizontal telescopic rod is connected to a first anchoring nail, and the other end is connected to the base; one end of the inclined telescopic rod is connected to a second anchoring nail, and the other end is connected to the base.

[0009] This utility model discloses a novel support arm applicable to irregular cable trays. The horizontal telescopic rod includes a first knob sleeve, a first threaded rod, and a second threaded rod. The two ends of the first knob sleeve are threadedly connected to the first and second threaded rods, respectively. The first threaded rod is connected to a first anchor pin, and the second threaded rod is connected to a base. The inclined telescopic rod includes a second knob sleeve, a third threaded rod, and a fourth threaded rod. The two ends of the second knob sleeve are threadedly connected to the third and fourth threaded rods, respectively. The third threaded rod is connected to a second anchor pin, and the fourth threaded rod is connected to a base.

[0010] This utility model discloses a novel support arm applicable to irregular cable trays, wherein a first anchoring nail is provided with a first connector, a second anchoring nail is provided with a second connector, a first threaded rod is provided with a third connector, the second threaded rod is fixedly mounted on a base, the third threaded rod is provided with a fourth connector, the fourth threaded rod is provided with a fifth connector, the first connector and the third connector are connected, the second connector and the fourth connector are connected, and the fifth connector is connected to the base.

[0011] This utility model discloses a novel support arm suitable for irregular cable trays, wherein the outer periphery of the first knob sleeve and the second knob sleeve are both provided with anti-slip texture.

[0012] This utility model discloses a novel support arm suitable for irregular surface cable trays, wherein the fixing clamp is a U-shaped clamp.

[0013] The difference between this utility model and the prior art is that this utility model uses two anchor nails to anchor and position on the irregular surface of the construction site to form a support structure. The base is connected to the first anchor nail by a horizontal telescopic rod, and the base is positioned by rotating the first knob sleeve. After positioning, the second anchor nail is connected to the base by an oblique telescopic rod. The positioned base is then adjusted to a horizontal state by rotating the second knob sleeve, forming a firm and stable triangular support structure. Finally, the cable tray is firmly fixed to the base by a fixing clamp.

[0014] The novel support arm of this utility model, applicable to irregular cable trays, includes at least the following beneficial effects:

[0015] (1) The anchor nail is directly fixed in the reserved hole on the irregular surface. This new type of bracket can be used for cable trays on various irregular surfaces (such as uneven, undulating, etc.) as well as for horizontal and vertical cable trays on regular surfaces, and has strong adaptability.

Detailed Implementation

[0029] like Figure 1As shown, this utility model provides a novel support arm for cable trays on irregular surfaces 04, including a fixing device 01. The fixing device 01 is fixed on the irregular surface 04 to form a support structure for the cable tray on the irregular surface 04.

[0030] Those skilled in the art will understand that by fixing the fixing device 01 to the irregular surface 04 at the construction site, a support base point for the cable tray (not shown in the figure) is formed on the irregular surface 04. Based on this support base point, other connecting structures are connected to it to form a support structure for the cable tray (i.e., a new type of bracket), overcoming the problem that conventional cable tray brackets cannot be positioned and installed on such an irregular surface 04.

[0031] Support device 03 is used to support and fix cable trays. Cable trays (not shown in the figure) contain cables or cables used for communication and other functions. Support device 03 is positioned at a preset position by fixing device 01 and connecting device 02, and the cable tray is firmly fixed to the cable support device 03. The cable tray usually has a certain length and needs to be supported by a new type of bracket at regular intervals. The cable tray is firmly fixed by the support device 03 on multiple new type of brackets.

[0032] The connecting device 02 is used to connect the fixing device 01 and the supporting device 03 to form a strong and stable cable tray support structure.

[0033] After the fixing device 01 forms a support base point on the irregular surface 04, the connecting device 02 is connected to the fixing device 01 (e.g., bolt connection), and the cable tray support device 03 is fixed to the connecting device 02, forming a new type of support arm structure for supporting the cable tray.

[0034] This new type of support arm can be used not only in installation environments with irregular surfaces (04) but also in environments with regular surfaces, demonstrating strong environmental adaptability and possessing certain promotional value.

[0035] like Figure 1 As shown, the fixing device 01 includes a first anchor nail 11 and a second anchor nail 12. The first anchor nail 11 and the second anchor nail 12 are firmly nailed along the up and down direction of the irregular surface 04 and maintain a certain distance.

[0036] The first anchor nail 11 and the second anchor nail 12 are the same, both being nail-shaped structures of a certain length to ensure the firmness of the installation. Depending on the construction site environment, the two anchor nails are nailed to the irregular surface 04. Holes can be pre-drilled in the irregular surface 04 using tools such as an electric drill to facilitate the installation of the anchor nails. During installation, the first anchor nail 11 and the second anchor nail 12 are nailed along the vertical direction of the irregular surface 04 and are spaced a certain distance apart. This helps to provide stable support. There is no special limitation on this distance; a suitable distance can be set according to the construction site conditions. This forms a support base point for the cable tray on the irregular surface 04, and the connecting device 02 and the supporting device 03 are fixed to the fixing device 01.

[0037] like Figure 1 As shown, the support device 03 includes a base 31 and a fixing clamp 32, which fixes the cable tray to the base 31 by bolts.

[0038] Base 31 is used to support cable trays, such as Figure 6 and Figure 7 As shown, the upper surface of the base 31 is provided with two through holes for connecting the fixing clamp 32. The fixing clamp 32 is a U-shaped clamp or other clamps with the same effect. During installation, the cable tray is placed between the two through holes of the base 31, and then the fixing clamp 32, i.e. the U-shaped clamp, is inserted into the two through holes on the base 31. Then, it is fixed with bolts to firmly fix the cable tray on the base 31.

[0039] like Figure 1 As shown, the connecting device 02 includes a horizontal telescopic rod 21 and an inclined telescopic rod 22. One end of the horizontal telescopic rod 21 is connected to the first anchor nail 11, and the other end is connected to the base 31. One end of the inclined telescopic rod 22 is connected to the second anchor nail 12, and the other end is connected to the base 31.

[0040] The left end of the horizontal telescopic rod 21 is bolted to the first anchor nail 11, and the right end is welded to the base 31. The left end of the inclined telescopic rod 22 is bolted to the second anchor nail 12, and the right end is bolted to the base 31. Because there is a certain distance between the two anchor nails, the first anchor nail 11, the second anchor nail 12 and the base 31 form a stable triangular structure. Moreover, all the components of this new type of support arm are bolted together, which makes installation and disassembly convenient, pipeline adjustment flexible, process modification and line adjustment convenient, improves the reusability of component materials, saves materials and reduces project costs.

[0041] The new type of support arm eliminates the need for welding and hot work during installation, which not only improves construction efficiency but also allows installation to be carried out in fire-prohibited areas, reducing fire risk and improving construction safety.

[0042] like Figure 1As shown, the horizontal telescopic rod 21 includes a first knob sleeve 211, a first threaded rod 212, and a second threaded rod 213. The two ends of the first knob sleeve 211 are threadedly connected to the first threaded rod 212 and the second threaded rod 213, respectively. The first threaded rod 212 is connected to the first anchoring nail 11, and the second threaded rod 213 is connected to the base 31. The inclined telescopic rod 22 includes a second knob sleeve 221, a third threaded rod 222, and a fourth threaded rod 223. The two ends of the second knob sleeve 221 are threadedly connected to the third threaded rod 222 and the fourth threaded rod 223, respectively. The third threaded rod 222 is connected to the second anchoring nail 12, and the fourth threaded rod 223 is connected to the base 31.

[0043] Both the horizontal telescopic rod 21 and the diagonal telescopic rod 22 have telescopic adjustment functions and similar structures. The first threaded rod 212 is threaded to the left end of the first knob sleeve 211 and bolted to the first anchor nail 11. The second threaded rod 213 is threaded to the right end of the first knob sleeve 211 and welded to the left side wall of the base 31. The third threaded rod 222 is threaded to the left end of the second knob sleeve 221 and bolted to the second anchor nail 12. The fourth threaded rod 223 is threaded to the right end of the second knob sleeve 221 and bolted to the left side wall of the base 31. Thus, the base 31 can be positioned by the horizontal telescopic rod 21. After determining the position according to the construction site, the base 31 is adjusted to the specified horizontal position by rotating the first knob sleeve 211. Then, the state of the base 31 is adjusted by rotating the second knob sleeve 221 to adjust it to a perfect position to match the cable tray (such as keeping the upper surface of the base 31 horizontal) to adapt to various complex environments.

[0044] It should be noted that the horizontal telescopic rod 21 and the diagonal telescopic rod 22 have similar structures. Both ends of the first knob sleeve 211 and the second knob sleeve 221 are respectively provided with internal threads with opposite directions of rotation. When the first knob sleeve 211 or the second knob sleeve 221 is rotated clockwise, the threaded rods at both ends of the first knob sleeve 211 or the second knob sleeve 221 are extended or shortened. When the two knob sleeves are rotated counterclockwise, the threaded rods at both ends of the first knob sleeve are shortened or extended, thereby realizing telescopic adjustment.

[0045] like Figure 1 As shown, a first connector 111 is provided on the first anchor nail 11, a second connector 121 is provided on the second anchor nail 12, a third connector 2121 is provided on the first threaded rod 212, a second threaded rod 213 is fixedly provided on the base 31, a fourth connector 2221 is provided on the third threaded rod 222, and a fifth connector 2231 is provided on the fourth threaded rod 223. The first connector 111 and the third connector 2121 are connected, the second connector 121 is connected to the fourth connector 2221, and the fifth connector 2231 is connected to the base 31.

[0046] like Figure 2 and Figure 3 As shown, the first connector 111 and the second connector 121 have the same structure. Both anchor bolts in the figure have single-piece connectors, but they can also be configured as double-piece connectors. Figure 4 and Figure 5 As shown, the third connector 2121, the fourth connector 2221, and the fifth connector 2231 are all double-piece designs, also known as U-shaped designs. Each connector has a through hole for bolts. The first connector 111 and the third connector 2121 are fixedly connected by bolts, and the second connector 121 and the fourth connector 2221 are fixedly connected by bolts. A sixth connector is welded to the left side of the base 31. The sixth connector has the same structure as the first connector 111. The fifth connector 2231 is fixedly connected to the sixth connector by bolts. During installation, the horizontal telescopic rod 21 positions the base 31, and the inclined telescopic rod 22 adjusts the base 31 to the optimal position (such as keeping the upper surface of the base 31 horizontal). The bolts of the relevant connectors are tightened to form a stable support structure, which firmly supports the cable tray. This new type of support arm is easy and quick to install, greatly improving construction efficiency.

[0047] like Figure 1 As shown, both the first knob sleeve 211 and the second knob sleeve 221 have anti-slip textures 23 on their outer periphery.

[0048] The anti-slip texture 23 increases the friction of the two knob sleeves, preventing slippage or poor adjustment accuracy when rotating the two knob sleeves to adjust the length of the horizontal telescopic rod 21 and the diagonal telescopic rod 22.

[0049] The installation steps are as follows:

[0050] 1. Drill two pre-drilled holes at the upper and lower fixing points on the irregular surface of the construction site (such as the uneven or undulating cross-section of the cable tray layout). A rechargeable portable impact drill can be used for on-site drilling to avoid temporary power supply arrangements during cable tray installation and reduce the safety risks of temporary power supply during on-site construction. Then, firmly nail the first anchor nail 11 and the second anchor nail 12 into the two pre-drilled holes.

[0051] 2. Use regular hexagonal bolts and nuts to connect the horizontal telescopic rod 21 to the first anchor nail 11 (i.e., connect the first connector 111 and the third connector 2121). After determining the position of the cable tray, adjust the length of the horizontal telescopic rod 21 by rotating the first knob sleeve 211 to extend the cable tray base 31 to the determined position.

[0052] 3. Rotate the second knob sleeve 221 to adjust the length of the inclined telescopic rod 22. In conjunction with the horizontal telescopic rod 21, support the base 31 to a horizontal position. After adjusting the length of the inclined telescopic rod 22, use regular hexagonal bolts and nuts to connect the inclined telescopic rod 22 to the second anchor nail 12 (i.e., connect the second connector 121 and the fourth connector 2221). Then use regular hexagonal bolts and nuts to connect the inclined telescopic rod 22 to the sixth connector on the base 31. Thus, the base 31 can reach the corresponding design position of the cable tray.

[0053] 4. Place the cable tray on the base 31, arrange the cables inside the cable tray, and then use the fixing clamps 32 (U-shaped clamps) to fix the cable tray to the base 31 with bolts to complete the cable installation.
