Description

Technical Field

[0001] This utility model relates to the field of seismic resistance technology for cable trays, specifically an environmentally friendly cable tray with a seismic-resistant structure. Background Technology

[0002] Cable trays are metal or non-metal structures used to support and protect cables, wires, and other wiring. They play a crucial role in power distribution systems, carrying power cables, wires, and cable ducts, and responsible for transmitting power from the power source to different electrical devices or areas, achieving efficient power distribution and transmission. The installation method of cable trays can be determined according to the installation conditions and environment of the site, and can be selected from different installation methods such as suspended, upright, side-wall, or hybrid methods. This versatility allows cable trays to adapt to various complex installation environments and needs.

[0003] In earthquake-prone areas, traditional cable trays are typically fixed with rigid connections. While simple, this method offers poor earthquake resistance, making them susceptible to damage or cable detachment due to vibrations. This can lead to power outages or even fires. Traditional cable trays are primarily designed to withstand vertical loads, offering weak lateral support. During an earthquake, the lack of effective lateral support can cause the piping system to sway significantly or even detach. Furthermore, existing cable trays are usually fixed in place and cannot be adjusted. When wiring needs modification, the cable trays must be removed and destroyed, which is contrary to environmental principles. Utility Model Content

A lifting column is slidably connected to the upper side of the pressure box, and a reset elastic element is fixedly connected between the lower surface of the lifting column and the upper surface of the crossarm. Connecting pipes are fixedly connected to both sides of the lower end of the pressure box, and the inside of the pressure box communicates with the inside of the supporting sleeve through the connecting pipes.

[0007] Preferably, the supporting cross frame has threaded grooves and notches evenly distributed on one side, and the fasteners are disposed inside the notches.

[0008] Preferably, the top support slider has a square cross-section.

[0009] Preferably, the traction unloading mechanism includes a hanging frame, a hanging bracket, and a return pressure cylinder. The hanging frame is fixedly connected to the upper surface of the cable tray cover, the hanging bracket is fixedly connected to the lower surface of the hanging plate, the hanging bracket penetrates the interior of the hanging frame and fits against the upper surface of the cable tray frame, the return pressure cylinder is fixedly connected to the lower surface of the hanging plate, a protrusion is fixedly connected to the lower inner wall of the return pressure cylinder, a compressed air sleeve is slidably connected to the upper inside of the return pressure cylinder, an inner piston pipe is fixedly connected to the lower surface of the compressed air sleeve, a connecting sleeve is fixedly connected to the bottom of the inner piston pipe, a top block is slidably connected to the inside of the connecting sleeve, the top block is fixedly connected to the upper surface of the hanging bracket and the lower surface of the hanging frame, and a spring is fixedly connected between the top blocks.

[0010] Preferably, the inner piston tube has an opening extending to the upper surface of the air compressor sleeve, and the outer side of the inner piston tube has a sliding groove.

[0011] Preferably, the connecting sleeve has an airflow channel inside.

[0012] Compared with the prior art, this utility model provides an environmentally friendly cable tray with an earthquake-resistant structure, which has the following beneficial effects:

[0013] 1. The buffer and shock absorption mechanism is used to lift the cable tray during an earthquake, preventing it from colliding with other solid objects and causing structural damage. This avoids the catastrophic consequences of damaged lines. Specifically, the cable tray is in a lifted state. When the cable tray is subjected to strong vibration, it experiences inertia due to gravity and begins to slide downwards. During this sliding process, air pressure is generated inside the pressure return cylinder. This air pressure is used to lift the cable tray, giving it an upward thrust that allows it to overcome inertial forces. The inertial forces of the cable tray then act on the air pressure, preventing the cable tray from colliding with other objects and thus avoiding damage.

[0014] 2. The traction unloading mechanism provides flexible restriction on the movement of the cable tray. It allows the cable tray to be pulled by air pressure, preventing it from moving significantly. This absorbs the force released from the initial shock of the buffer and damping mechanism, preventing large displacement of the cable tray. It also helps to lock the cable tray and further disperse its inertia. Moreover, this mechanism is driven by the displacement of the cable tray. The greater the inertia of the cable tray, the stronger the support force, in order to cope with stronger earthquakes. Attached Figure Description

[0024] Example 1:

[0025] Please see Figure 1-5 This utility model provides a technical solution: an environmentally friendly cable tray with an anti-seismic structure, including a threaded hanging rod 1, a crossbeam 2 sleeved on the threaded hanging rod 1, a limiting member 3 for fastening the crossbeam 2, a cable tray frame 4 set on the upper side of the crossbeam 2, a cable tray cover 5 sleeved on the cable tray frame 4, and a hanging plate 6 set on the upper side of the cable tray cover 5. A buffer and shock absorption mechanism 7 is set on the lower side of the cable tray frame 4, and a traction unloading mechanism 8 is set on the upper side of the cable tray cover 5.

[0026] Furthermore, the buffer and shock absorption mechanism 7 includes a support cross frame 701, which is fixedly connected to the lower surface of the cable tray frame 4. A top support slider 702 is slidably connected inside the support cross frame 701. A fastener 703 is threadedly connected between the support cross frame 701 and the top support slider 702. A support sleeve 704 is fixedly connected to the upper surface of the crossarm 2. A slide 705 is slidably connected inside the support sleeve 704. A spreading elastic element 706 is fixedly connected between the lower surface of the slide 705 and the upper surface of the crossarm 2. A pressure box 707 is fixedly connected to the upper surface of the crossarm 2. 707 is located in the middle of the support sleeve 704. The upper side of the air pressure box 707 is sealed and slidably connected to the lifting column 708. The lower surface of the lifting column 708 is fixedly connected to the upper surface of the crossbeam 2. The lower ends of the air pressure box 707 are fixedly connected to the two sides of the connecting pipe 710. The air pressure box 707 is connected to the inside of the support sleeve 704 through the connecting pipe 710. The slide 705 is lowered by the inertia generated by the gravity of the cable tray during strong vibration. The air pressure generated by the slide 705 is used to lift the cable tray, which facilitates the unloading of the downward displacement of the cable tray.

[0027] Furthermore, threaded grooves and notches are evenly provided on one side of the support frame 701, and fasteners 703 are set inside the notches to prevent the cable tray from moving and to facilitate adjustment of the cable tray position when needed.

[0028] Furthermore, the top support slider 702 has a square cross-section.

[0029] Example 2:

[0030] Please see Figure 1-5 Furthermore, in conjunction with Embodiment 1, the traction unloading mechanism 8 includes a hanging frame 801, a hanging bracket 802, and a return pressure cylinder 803. The hanging frame 801 is fixedly connected to the upper surface of the cable tray cover 5, and the hanging bracket 802 is fixedly connected to the lower surface of the hanging plate 6. The hanging bracket 802 penetrates the interior of the hanging frame 801 and fits against the upper surface of the cable tray frame 4. The return pressure cylinder 803 is fixedly connected to the lower surface of the hanging plate 6. A protrusion 804 is fixedly connected to the lower inner wall of the return pressure cylinder 803. A compressed air sleeve 805 is slidably connected to the upper sealed interior of the return pressure cylinder 803. An internal piston pipe 80 is fixedly connected to the lower surface of the compressed air sleeve 805. 6. The bottom of the inner piston tube 806 is fixedly connected to a connecting sleeve 807. The connecting sleeve 807 is slidably connected to a top block 808. The top block 808 is fixedly connected to the upper surface of the bracket 802 and the lower surface of the frame 801. A spring 809 is fixedly connected between the top blocks 808. At the same time, when the bridge box is displaced, the top block 808 is displaced. Since the hanging plate 6 is in a fixed state, when the top block 808 moves, a negative pressure is generated on the upper side of the back pressure cylinder 803. The negative pressure is used to restrict the movement of the top block 808, so that the top block 808 is always at the same level, which can conveniently share the remaining force of the bridge.

[0031] Furthermore, the inner piston tube 806 has an opening extending to the upper surface of the air compressor sleeve 805, and the inner piston tube 806 has a sliding groove on its outer side.

[0032] Furthermore, an airflow channel is provided inside the connecting sleeve 807.

[0033] In actual operation, when this device is used, the user places the cable tray frame 4 in a suitable position and fixes the cable tray frame with fasteners 703. Then, the cable tray cover 5 is fitted onto the cable tray frame 4 and the two are fixedly connected. In the event of an earthquake, the cable tray will shake violently due to its own weight. The displacement of the cable tray causes the slide 705 to move down. The movement of the slide 705 generates air pressure. The air pressure pushes the lifting column 708 to lift the cable tray and prevent the cable tray from displacing significantly. At the same time, when the top block 808 moves, the back pressure cylinder 803 generates negative pressure. The negative pressure pulls the top blocks 808 closer together, further supporting the cable tray and preventing it from moving. The air pressure lifting method can prevent the cable tray from shaking significantly. At the same time, the compressibility of gas allows the cable tray to be flexibly limited, preventing the cable tray from being vibrated and collided.
