Description

Technical Field

[0001] This invention relates to the field of cable tray technology, and in particular to a composite material cable tray with a canopy that can be quickly assembled. Background Technology

[0002] Composite materials endow cable trays with excellent electrical insulation, corrosion resistance and flame retardancy, making them particularly suitable for the harsh and special climatic environment of offshore oil drilling platforms. However, a major problem faced by composite material cable trays in practical applications is how to improve the load-bearing capacity of the cable trays to meet the limited space of offshore oil drilling platforms that allows for the laying of a larger number of cables to meet the power supply needs of the equipment.

[0003] Ordinary composite material cable trays consist of C-shaped or E-shaped steel, crossbars, and connectors. The bottom of the side plates of the C-shaped or E-shaped steel have fixing holes for connecting to the crossbars. The C-shaped or E-shaped steel is fixed to the crossbars via connectors. As the number of cables laid increases, the downward bending moment of the C-shaped or E-shaped steel on both sides of the cable tray increases, and the side plates expand outwards. This causes localized delamination and cracking at the interface between the upper and lower plates of the C-shaped or E-shaped steel and the side plates, leading to twisting damage of the C-shaped or E-shaped steel. During the twisting process, the fixing holes connecting the C-shaped or E-shaped steel side plates to the crossbars tear. The connection between ordinary cable trays is usually fixed to the outside of C-shaped or E-shaped steel side plates by external multi-directional and unidirectional connecting plates. Under the long-term load of the cable, when the C-shaped or E-shaped steel side plates bend downward and expand outward, cracks or even breaks appear in the bolt fixing holes of the external connecting plates. Ultimately, the external connecting plates collapse outward, causing the entire cable tray to collapse. These failures not only affect the normal laying of cables, but may also cause the shutdown of offshore oil drilling platform equipment, resulting in serious economic losses and safety hazards.

[0004] Therefore, in order to solve the above problems, a more suitable facility that meets the needs of users is needed. Summary of the Invention

[0005] In view of this, the purpose of this invention is to provide a composite material cable tray with a canopy that can be quickly assembled, so as to solve the problem of tearing of the side plate fixing holes and breakage of the connectors caused by the above-mentioned cable tray under the long-term load of the cable.

[0006] Based on the above objectives, the present invention provides a composite material cable tray with a canopy that can be quickly assembled, comprising two basic profiles, with limiting plates fixedly connected to a pair of adjacent sides of the two basic profiles, and a fixing plate fixedly connected to the basic profiles below the limiting plates. A boss is fixedly connected to one end of the fixing plate, and a sliding groove sidewall is fixedly connected to the other end of the fixing plate together with the limiting plate. A sliding groove is formed between the fixing plate, the limiting plate, and the sliding groove sidewall. Several horizontal bars are arranged sequentially between the two base profiles. The two ends of the horizontal bars are respectively provided with slots that cooperate with the bosses. The two ends of the horizontal bars are respectively slidably installed in two sliding grooves. Several first rectangular tubes are slidably installed in the sliding grooves. The side ends of the horizontal bars and the first rectangular tubes are sequentially and alternately installed in the corresponding sliding grooves. The base profiles are provided with abutting and fastening structures for abutting the horizontal bars located on both sides. The tops of the two base profiles are connected by a canopy shielding component.

[0007] Optionally, the abutment fastening structure includes a second rectangular tube and a third rectangular tube slidably installed in the groove. Fasteners that cooperate with the second rectangular tube and the third rectangular tube are installed on the base profile. The first rectangular tube and the crossbar are both located between the second rectangular tube and the third rectangular tube. The two ends of the first rectangular tube are in contact with the two crossbars respectively. The second rectangular tube is in contact with one of the crossbars located on one side. The third rectangular tube is equipped with an abutment member facing the crossbar for abutting against the other crossbar located on one side.

[0008] Optionally, the fastener includes a plurality of first bolts that penetrate the second rectangular tube and the third rectangular tube, and the first bolts penetrate the fixing plate and the limiting plate, with a nut sleeved at the bottom end of the first bolt located below the fixing plate.

[0009] Optionally, the abutment includes a base disposed on the side of the third rectangular tube facing the crossbar, the end face of the third rectangular tube abutting the end face of the base away from the crossbar, a threaded tube fixedly connected to the inner wall of the base, the base being slidably installed in the groove, a limiting plate and a fixing plate being fixedly connected to the base by a first fixing pin, a second bolt passing through the base and screwed onto the threaded tube, a movable plate being provided inside the third rectangular tube, slots that mate with the movable plate being opened on the inner walls of both sides of the third rectangular tube, the first bolt also passing through the movable plate, one end of the second bolt contacting the corresponding crossbar, and the other end of the second bolt contacting the movable plate.

[0010] Optionally, the crossbar is a square tube, and a rigid steel frame is fixedly connected to the inner wall of the crossbar.

[0011] Optionally, the canopy shielding assembly includes a rain shield plate disposed above the base profile. The two rain shield plates are connected by a connector. An upper wing plate is fixedly connected to the top of the base profile, and a lower wing plate is fixedly connected to the bottom of the base profile. Two connecting plates are fixedly connected to the rain shield plate. Two T-shaped grooves are formed on the upper wing plate. A T-shaped tenon located in the T-shaped groove is fixedly connected to the bottom of the connecting plate. The T-shaped tenon and the T-shaped groove are fixedly connected by epoxy resin adhesive.

[0012] Optionally, two adjacent connecting plates are fixedly connected by a reinforcing plate.

[0013] Optionally, the connector includes a connecting seat disposed between two rain shields, with insertion slots on both sides of the connecting seat, and the two rain shields having their adjacent ends inserted into the two insertion slots respectively, and the rain shields and the connecting seat being connected by a number of second fixing pins.

[0014] Optionally, a rectangular cavity is formed on the base profile.

[0015] The beneficial effects of this invention are as follows: The operator alternately slides the two ends of the crossbar and the first rectangular tube into the grooves of the two base profiles, respectively, so that the two ends of the first rectangular tube contact the two crossbars respectively, and the slots of the crossbars are embedded in the bosses. The bosses slide into the slots, and the position of the crossbars is positioned by the limiting plate and the bosses, preventing the crossbars from swaying vertically and to the left and right relative to the base profiles. Then, the first rectangular tube is slid into the groove, and the ends of the crossbars and the first rectangular tubes are alternately slid into the groove. After the first rectangular tubes and crossbars are installed, the crossbars on both sides are abutted by the abutment fastening structure and abutment parts, so that the two end faces of the first rectangular tubes are tightly attached to the side end faces of the adjacent crossbars, thereby fixing the crossbars and the first rectangular tubes relative to the base profiles. The tops of the two base profiles are connected by the canopy shielding component, and the slots at both ends of the crossbars are inserted into the bosses of the base profiles, which restricts the freedom of movement of the crossbars to the left and right. By using the boss and the first rectangular tube to limit the horizontal position of the crossbar, and in conjunction with the setting of the sliding groove, the first rectangular tube is embedded in the sliding groove between adjacent crossbars. The two ends of the first rectangular tube are tightly attached to the side ends of the adjacent crossbars, and the abutting fastening structure and abutting parts abut against the crossbars on both sides, preventing the crossbars and the first rectangular tube from sliding in the sliding groove, thus restricting the freedom of movement of the crossbars forward and backward. The lower plane of the limiting plate presses tightly against the upper plane of the crossbars, the first rectangular tube, the second rectangular tube, the base, and the third rectangular tube, thus restricting the freedom of movement of the crossbars up and down. This allows for the fixing of several crossbars. The installation and fixing of each crossbar does not require fixing holes to be opened on the base profile, which solves the problem that ordinary composite material cable trays usually have fixing holes opened on the side plates and the side plates are fixed to the crossbars through connectors. Under the long-term load of the cable trays, the fixing holes of the side plates are torn and the connectors are broken. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0020] Example 1, by Figure 1 , Figure 2, Figure 4 , Figure 5 and Figure 8 The present invention includes two basic profiles 1, with a limiting plate 4 fixedly connected to a pair of adjacent sides of the two basic profiles 1, and a fixing plate 35 located below the limiting plate 4 fixedly connected to the basic profiles 1. A boss 3 is fixedly connected to one end of the fixing plate 35, and a slide groove sidewall 34 is fixedly connected to the other end of the fixing plate 35 together with the limiting plate 4. A slide groove 2 is formed between the fixing plate 35, the limiting plate 4 and the slide groove sidewall 34. Between two basic profiles 1, several horizontal bars 5 are arranged in sequence. At each end of the horizontal bar 5, a groove 6 is provided to mate with a boss 3. The ends of the horizontal bars 5 are slidably installed in two sliding grooves 2. Several first rectangular tubes 7 are slidably installed in the sliding grooves 2. The side ends of the horizontal bars 5 and the first rectangular tubes 7 are staggered and installed in corresponding sliding grooves 2. The basic profile 1 is equipped with abutting and fastening structures to abut the horizontal bars 5 located on both sides. The tops of the two basic profiles 1 are connected by a canopy covering assembly. The operator alternately slides the ends of the horizontal bars 5 and the first rectangular tubes 7 into the two sliding grooves 2. Inside the slide groove 2, the two ends of the first rectangular tube 7 are respectively in contact with the two crossbars 5, and the slots 6 of the crossbars 5 are embedded in the bosses 3. The bosses 3 slide into the slots 6, and the position of the crossbars 5 is positioned by the limiting plate 4 and the bosses 3 to prevent the crossbars 5 from swaying vertically and to the left and right relative to the base profile 1. Then the first rectangular tube 7 is slid into the slide groove 2. The ends of the crossbars 5 and the first rectangular tube 7 are slid into the slide groove 2 in an alternating manner. After the first rectangular tube 7 and the crossbars 5 are installed, the crossbars 5 on both sides are abutted by the abutment fastening structure and abutment parts, so that the two end faces of the first rectangular tube 7 are tightly attached to the side end faces of the adjacent crossbars 5. This design secures the horizontal bar 5 and the first rectangular tube 7 relative to the base profile 1. The tops of the two base profiles 1 are connected by a canopy covering assembly, and the slots 6 at both ends of the horizontal bar 5 are inserted into the bosses 3 of the base profile 1, restricting the left and right movement of the horizontal bar 5. The bosses 3 and the first rectangular tube 7 limit the horizontal position of the horizontal bar 5. In conjunction with the sliding groove 2, the first rectangular tube 7 is embedded in the sliding groove 2 between adjacent horizontal bars 5. The two end faces of the first rectangular tube 7 are tightly fitted to the side end faces of the adjacent horizontal bars 5. The abutment fastening structure and abutment members abut against the horizontal bars 5 located on both sides, preventing the horizontal bar 5 and the first rectangular tube 7 from sliding... The sliding within the groove 2 restricts the freedom of movement of the crossbar 5 in the forward and backward directions. The lower plane of the limiting plate 4 presses tightly against the upper planes of the crossbar 5, the first rectangular tube 7, the second rectangular tube 8, the base 12, and the third rectangular tube 9, restricting the freedom of movement of the crossbar 5 in the up and down directions. This allows for the fixation of several crossbars 5. The installation and fixation of each crossbar 5 does not require the opening of fixing holes in the base profile 1. This solves the problem that ordinary composite material cable trays usually have fixing holes on the side plates, and the side plates are fixed to the crossbars through connectors. Under the long-term load of the cable trays, the fixing holes of the side plates are torn and the connectors are broken and damaged.

[0021] Example 2, based on Example 1, is... Figure 2 , Figure 6 , Figure 7 and Figure 8 The fastening structure includes a second rectangular tube 8 and a third rectangular tube 9 slidably installed in the groove 2. Fasteners that mate with the second rectangular tube 8 and the third rectangular tube 9 are installed on the base profile 1. A first rectangular tube 7 and a crossbar 5 are located between the second rectangular tube 8 and the third rectangular tube 9. Both ends of the first rectangular tube 7 contact the two crossbars 5 respectively. The second rectangular tube 8 contacts one of the crossbars 5 located on one side. A contacting member for abutting against the other crossbar 5 located on one side is installed on the side of the third rectangular tube 9 facing the crossbar 5. The fasteners include several first bolts 10 that penetrate the second rectangular tube 8 and the third rectangular tube 9, and the first bolts 10 penetrate the fixing plate 35 and the limiting plate 4. A screw thread located below the fixing plate 35 is sleeved at the bottom end of the first bolt 10. The female part 11 and the abutment part include a base 12 disposed on the side of the third rectangular tube 9 facing the crossbar 5. The end face of the third rectangular tube 9 is attached to the end face of the base 12 away from the crossbar 5. A threaded tube 14 is fixedly connected to the inner wall of the base 12. The base 12 is slidably installed in the slide groove 2. The limiting plate 4 and the fixing plate 35 are fixedly connected to the base 12 by the first fixing pin 15 respectively. A second bolt 13 passes through the base 12 and is screwed onto the threaded tube 14. A movable plate 16 is provided inside the third rectangular tube 9. Slots 17 that cooperate with the movable plate 16 are opened on the inner walls of both sides of the third rectangular tube 9 respectively. The first bolt 10 also passes through the movable plate 16. One end of the second bolt 13 contacts the corresponding crossbar 5, and the other end of the second bolt 13 contacts the movable plate 16. The operator slides the second rectangular tube 8 into one end of the slide groove 2, and secures it in place using the first bolt 10 and nut 11. Then, the operator slides the end of the crossbar 5 into the slide groove 2 from the other end. Next, the operator slides the first rectangular tube 7 into the slide groove 2. The operator then alternately slides the ends of the crossbars 5 and the first rectangular tubes 7 into the slide groove 2 until the end of the last crossbar 5 is in place. The operator then slides the base 12 into the slide groove 2, moving it to one side of the last crossbar 5. The base 12 is then secured in place using the first fixing pin 15. The operator drives the second bolt 13 to rotate relative to the threaded tube 14 until one end of the second bolt 13 abuts against the side end of the crossbar 5. The operator then slides the third rectangular tube 9 into the slide groove 2, and the two sides of the moving plate 16 slide into the two slots 17. The operator drives the first bolt 10 through the third rectangular tube 9 and the moving plate 16. The operator then fits the nut 11 onto the slide groove 2. Outside the first bolt 10, the first bolt 10 and nut 11 cooperate to fix the moving plate 16 and the third rectangular tube 9 relative to the slide groove 2. At this time, one end face of the third rectangular tube 9 is attached to the end face of the base 12 away from the crossbar 5, which further strengthens the firmness of the base 12 and the slide groove 2. The end of the moving plate 16 facing the base 12 and the end of the second bolt 13 away from the crossbar 5 are relatively abutted, which prevents the second bolt 13 from rotating relative to the threaded tube 14, and completes the locking of the position of the second bolt 13. This ensures that the second bolt 13 is kept abutting against the crossbar 5, thereby preventing the crossbar 5 and the first rectangular tube 7 from shaking and sliding relative to the slide groove 2. One end of the second bolt 13 is pressed tightly against the side end of the crossbar 5, and the end of the moving plate 16 is pressed tightly against the end of the second bolt 13 away from the crossbar 5, which effectively prevents the second bolt 13 from rotating and retreating. This eliminates the gap between the crossbar 5, the first rectangular tube 7 and the second rectangular tube 8 caused by installation, and improves the structural stability and reliability of the cable tray.

[0022] Example 3, based on Example 1, is... Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 8 and Figure 9As shown, the crossbar 5 is a square tube, and a rigid steel frame 29 is fixedly connected to the inner wall of the crossbar 5. The canopy shielding assembly includes a rain shield 18 set above the base profile 1. The two rain shields 18 are connected by a connector. An upper wing plate 19 is fixedly connected to the top of the base profile 1, and a lower wing plate 27 is fixedly connected to the bottom of the base profile 1. Two connecting plates 20 are fixedly connected to the rain shield 18. Two T-shaped grooves 22 are opened on the upper wing plate 19. The bottom of the connecting plate 20 is fixedly connected to a component located in the T-shaped groove 27. The T-shaped tenon 21 and T-shaped groove 22 in 2 are fixedly connected by epoxy resin adhesive. Two adjacent connecting plates 20 are fixedly connected by reinforcing plate 23. The connector includes a connecting seat 24 disposed between two rain shields 18. The two sides of the connecting seat 24 are respectively provided with insertion slots 25, and the two rain shields 18 are respectively inserted into the two insertion slots 25. The rain shields 18 and the connecting seat 24 are connected by several second fixing pins 26. A rectangular cavity 28 is provided on the base profile 1. The bottom of the rain shelter 18 is provided with two connecting plates 20, and a reinforcing plate 23 is connected between the two connecting plates 20 to enhance the wind load resistance between the two connecting plates 20. The cavity of the crossbar 5 is provided with a rigid steel frame 29. The square tube of the crossbar 5 and the rigid steel frame 29 are integrally composited by pultrusion process to improve the rigidity and bending strength of the crossbar 5. The bottom of the two connecting plates 20 is connected with a T-shaped tenon 21 that matches the T-shaped groove 22 in the base profile 1. The T-shaped tenon 21 slides into the T-shaped groove 22, and the T-shaped tenon 21 and the T-shaped groove 22 are fixedly connected by epoxy resin adhesive, which can facilitate the convenient and quick installation of the rain shelter 1. 8. A connector is installed between the two rain shields 18. The connecting seat 24 has insertion slots 25 on both sides that match the rain shields 18. A second fixing pin 26 passes through the rain shield 18 and the connecting seat 24, fixing the rain shield 18 and the connecting seat 24 to form a rain grille. The design of the upper wing plate 19 and the lower wing plate 27 increases the load-bearing area of ​​the base profile 1, improves the bending and torsional strength of the base profile 1, increases the number of cables that can be laid, and solves the problem of the C-shaped steel on both sides of the cable tray becoming insufficient as the number of cables increases. The increased bending moment of the E-shaped steel due to downward bending and the outward expansion of the side plates can cause localized delamination and cracking at the interface between the upper and lower plates of the C-shaped or E-shaped steel and the side plates, leading to twisting damage. To address this, a rectangular cavity 28 is provided inside the base profile 1. An external multi-directional or one-directional connecting plate is inserted into the rectangular cavity 28 of the adjacent cable tray base profile 1, achieving connection and fixation between adjacent cable trays. Furthermore, the freedom of the external multi-directional or one-directional connecting plate is restricted within the rectangular cavity 28 of the base profile 1, solving the problem of using external connections between adjacent cable trays. The method of fixing the connecting plate to the outside of the C-shaped or E-shaped steel side plate avoids the problem of the side plate expanding outward under long-term load, causing the external connecting plate to collapse and the entire cable tray to collapse. This type of composite material cable tray is molded from fiber-reinforced resin-based composite material, which has high electrical insulation and corrosion resistance, excellent safety and corrosion resistance, avoids unnecessary accidents and can be used in harsh environments for a long time without frequent maintenance, significantly reducing maintenance costs during use. Moreover, it can be modularly produced in the factory, reducing construction costs.
