Description

Technical Field

[0001] This utility model relates to the field of metal cable tray installation technology, specifically a modular installation structure for metal cable trays. Background Technology

[0002] As we all know, with the rapid development of existing building, power and communication infrastructure, metal cable trays, as the core carrier for cable laying, have become a focus of industry attention in terms of installation efficiency, structural stability and ease of maintenance.

[0003] Traditional cable tray installation techniques generally use welding or bolt fixing methods, which meet basic requirements to a certain extent, but have revealed significant defects in practical applications.

[0004] Specifically, welding processes rely on specialized equipment and operators, have long on-site construction cycles, and the irreversible connection method requires overall cutting when expanding or adjusting the layout of the circuit later, resulting in resource waste and a surge in maintenance costs. While bolt fixing is detachable, it requires precise hole alignment and repeated calibration during installation, and lacks multi-level locking and self-locking functions. It is prone to failure in industrial scenarios with frequent vibrations, making it difficult to guarantee long-term stability. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a modular installation structure for metal cable trays.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a modular installation structure for a metal cable tray, comprising a cable tray body, wherein auxiliary installation slides are provided on both sides of one end of the cable tray body, and auxiliary installation slide bars are provided on both sides of the other end. The auxiliary installation slide bars pass through the auxiliary installation slides and are slidably connected to them with damping. A connecting box is provided on the outside of the auxiliary installation slides, and symmetrical installation components are provided on both sides of the connecting box. The installation components are used to lock the auxiliary installation slides and the auxiliary installation slide bars, and a locking device is provided at one end of the installation components.

[0009] To achieve automatic hole locking between cable tray sections, this utility model improves upon the following: the installation assembly includes a support box, springs, support blocks, and support columns. The support box is connected to the side wall of the connecting box. A cavity is provided inside the support box. Multiple sets of springs are arranged within the cavity. The support block is located on the bottom wall of the support box and is slidably connected to it. One end of each spring is connected to the inner side wall of the cavity, and the other end is connected to the support block. The support columns are symmetrically arranged, passing through the support blocks and being fixedly connected to them. The support columns also pass through the support box and are slidably connected to it. An auxiliary installation slide is provided with an auxiliary hole. The auxiliary installation slide has multiple sets of symmetrical installation holes. The support columns pass through the auxiliary holes and the corresponding installation holes and are slidably connected to them.

[0010] To form a dual locking mechanism, the present invention is improved as follows: the locking device includes a limiting block, a locking block and a locking screw; the upper side wall of the support box is provided with a locking block; one end of the support column is provided with a limiting block; the limiting block connects the two support columns; and the locking screw passes through the limiting block and the locking block and is threadedly connected to them.

[0011] To avoid spring deformation caused by lateral force, the present invention is improved in that the spring axis is parallel to the support column axis.

[0012] To reduce sliding friction loss between the support column and the mounting hole, the present invention improves upon this invention by coating the surface of the support column with a wear-resistant coating, the coating material being titanium nitride or hard alloy.

[0013] To increase the contact area between the slide rail and the slide bar, the present invention is improved by having the following features: the cross-section of the auxiliary mounting slide rail is T-shaped, and the cross-section of the auxiliary mounting slide bar is a groove that matches the T-shaped slide rail.

[0014] To reduce noise and the risk of loosening, the present invention is improved by using rubber as the damping material for the damping sliding connection, which is embedded in the inner wall of the slide.

[0015] To prevent corrosion of the metal substrate, the present invention is improved by coating the surfaces of the auxiliary mounting slide and the auxiliary mounting strip with a zinc-nickel alloy anti-corrosion layer.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a modular installation structure for metal cable trays, which has the following advantages:

[0018] The modular installation structure of this metal cable tray is equipped with auxiliary installation slides and sliders. Through its damping sliding connection design, the cable tray sections can slide freely along the slides during splicing, eliminating the need for precise manual alignment and greatly simplifying the operation process.

[0019] Equipped with mounting components, multiple sets of springs drive the support blocks and support columns in linkage. After the slide bar is inserted into the slide rail, the support column can automatically insert into the mounting hole on the slide bar to form a pre-lock, reducing manual intervention. It is especially suitable for high-altitude or confined space operations.

[0020] The sliding engagement between the slider and the track allows for length adjustment of the cable tray section. By sliding to select the mounting holes and support columns at different positions on the slider, millimeter-level precision fine-tuning can be achieved, effectively eliminating the cumulative error when splicing multiple cable tray sections. Combined with the resistance control of the damping sliding connection, it can prevent accidental displacement of the slider and ensure a smooth and controllable adjustment process.

[0029] Please see Figure 1-4 A modular installation structure for a metal cable tray includes a cable tray body 1. Auxiliary installation slides 8 are provided on both sides of one end of the cable tray body 1, and auxiliary installation slide bars 7 are provided on both sides of the other end. The auxiliary installation slide bars 7 pass through the auxiliary installation slides 8 and are slidably connected to them with damping. A connecting box 2 is provided on the outer side of the auxiliary installation slides 8. Symmetrical installation components are provided on both sides of the connecting box 2. The installation components are used to lock the auxiliary installation slides 8 and the auxiliary installation slide bars 7. A locking device is provided at one end of each installation component. The installation component includes a support box 3, a spring 11, a support block 10, and a support column 9. The support box 3 is connected to the side wall of the connecting box 2, and a cavity is provided inside the support box 3. The springs 11 are arranged in multiple groups within the cavity. The support block 10 is slidably connected to the bottom wall of the support box 3. One end of the spring 11 is connected to the inner side wall of the cavity, and the other end is connected to the support block 10. The support columns 9 are symmetrically arranged, passing through the support block 10 and being fixedly connected to it. The support columns 9 also pass through the support box 3 and are slidably connected to it. The auxiliary mounting slide 8 is provided with auxiliary holes. The auxiliary mounting slide 7 is provided with multiple sets of symmetrical mounting holes 12. The support columns 9 pass through the auxiliary holes and the corresponding mounting holes 12 and are slidably connected to them. The damping material of the damping sliding connection is rubber, which is embedded in the inner wall of the slide.

[0030] During use, align the two cable tray bodies 1 to be assembled. Insert the auxiliary installation slide 7 (with multiple sets of symmetrical installation holes 12) of one section into the auxiliary installation slide 8 of the other section. The rubber damping material embedded in the inner wall of the slide provides moderate resistance, preventing the slide from sliding freely while allowing smooth movement when manually applied, ensuring the stability of the initial positioning of the cable tray section. The operator manually pulls the support column 9 (two symmetrically arranged columns) outward, causing the support block 10, which is fixedly connected to the support column 9, to slide within the support box 3, compressing multiple sets of springs 11. At this time, the support column 9 completely disengages from the auxiliary holes on the slide and the installation holes 12 on the slide, releasing the locking state of the slide. The cable tray section enters the length adjustment mode. Keeping the support column 9 in the pulled-out state, slide the slide along the slide to the target position. Multiple sets of mounting holes 12 on the slider are arranged at equal intervals. By sliding, a set of mounting holes 12 aligned with the slide rail is selected (for example, the innermost mounting hole 12 of the slider corresponds to the "zero gap" state where the cable tray sections are completely aligned; other holes allow a certain gap between the cable tray sections). The pulled-out support column 9 is released, the spring 11 releases its elastic force, pushes the support block 10 back, and drives the support column 9 to move towards the slide rail. When the slider slides to a certain position, if the mounting hole 12 on it is aligned with the auxiliary hole of the slide rail, the support column 9 automatically passes through the auxiliary hole and the mounting hole 12 under the push of the spring 11, forming a mechanical lock. This process does not require manual adjustment of the hole alignment, realizing "blind insertion" self-locking, which is especially suitable for high-altitude or limited-view scenarios. After the support column 9 is inserted, it is further reinforced by the locking device.

[0031] In practical use, a dual locking mechanism is required to improve long-term stability. To meet the above requirements, in this embodiment, the locking device includes a limiting block 4, a locking block 6, and a locking screw 5. The upper sidewall of the support box 3 is provided with a locking block 6, and one end of the support column 9 is provided with a limiting block 4. The limiting block 4 connects the two support columns 9, and the locking screw 5 passes through the limiting block 4 and the locking block 6 and is threadedly connected to them.

[0032] When the support column 9 passes through the mounting hole 12, the locking block 6 coincides with the limiting block 4. The locking screw 5 can be rotated by hand to pass through the limiting block 4 at the top of the support column 9 and the locking block 6 on the support box 3. The self-locking characteristic of the thread forms a rigid constraint, further preventing the support column 9 from retracting due to vibration or external force.

[0033] In actual use, it is necessary to avoid frictional loss or deformation of spring 11 caused by lateral force and extend the life of the component. In order to meet the above requirements, in this embodiment, the axis of spring 11 is parallel to the axis of support column 9.

[0034] In actual use, it is necessary to reduce the sliding friction loss between the support column 9 and the mounting hole 12. In order to meet the above requirements, in this embodiment, the surface of the support column 9 is coated with a wear-resistant coating, and the coating material is titanium nitride or hard alloy.

[0035] In practical use, it is necessary to increase the contact area and shear strength between the slide and the slide bar to prevent slippage under lateral force. In order to meet the above requirements, in this embodiment, the cross-section of the auxiliary mounting slide 8 is T-shaped, and the cross-section of the auxiliary mounting slide bar 7 is a groove that matches the T-shaped slide.

[0036] In actual use, a dense oxide film needs to be formed to prevent corrosion of the metal substrate. In order to meet the above requirements, in this embodiment, the surfaces of the auxiliary mounting slide 8 and the auxiliary mounting strip 7 are coated with a zinc-nickel alloy anti-corrosion layer.

[0037] To illustrate the possible application scenarios, technical principles, implementable specific solutions, and achievable objectives and effects of this application in detail, the following description, in conjunction with the listed specific embodiments and accompanying drawings, provides a detailed explanation. The embodiments described herein are merely illustrative of the technical solutions of this application and are therefore intended to limit the scope of protection of this application.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
