Description

Technical Field

[0001] This utility model belongs to the technical field of offshore oil drilling platforms, specifically relating to a multi-directional cable tray that can be quickly assembled. Background Technology

[0002] In recent years, with the development of industrial technology, especially in special environments such as offshore oil drilling platforms, higher requirements have been placed on the corrosion resistance and fire safety of cable trays. Composite material cable trays, due to their excellent corrosion resistance and flame retardant properties, have gradually become the preferred choice for these demanding companies. However, a major problem faced by composite material cable trays in practical applications is insufficient strength at the joints and internal connections, resulting in low assembly efficiency, especially in multi-directional cable trays.

[0003] Traditional composite cable tray connections typically use molded connectors fixed to the outside of the cable tray side panels. While these molded connectors possess a certain level of mechanical strength, their low fiber content results in poor overall strength. Furthermore, to achieve cable tray connections in different directions, various molded connectors with different angles need to be produced, which not only increases the number of molds but also significantly raises production costs.

[0004] More seriously, while cable trays bear the load of cables over long periods, they are also affected by vibrations generated by the operation of equipment on offshore oil drilling platforms, forcing the entire cable tray to resonate slightly. In this situation, the side plates of the cable tray are prone to outward expansion, causing cracks or even breakage in the bolt holes of the molded connectors. Ultimately, this leads to the connectors collapsing outward, causing the entire cable tray to collapse. This type of failure not only affects the normal laying of cables but may also cause the offshore oil drilling platform equipment to stop operating, resulting in serious economic losses and safety hazards.

[0018] This utility model has the following beneficial effects:

[0019] 1. This utility model significantly improves the connection strength within and between horizontal, vertical, and corner cable trays by using multi-directional connecting plates and unidirectional connecting plates for connection, and a dual fixing method of nut sleeves and fixing pins. In particular, the connection components are inserted into the rectangular cavity of the E-shaped steel and fixed with bolts, which restricts the freedom of the connection components within the rectangular cavity of the E-shaped steel. The fixing pins pass through the mounting holes of the E-shaped steel and the crossbars for secondary fixing, ensuring the overall stability and vibration resistance of the cable tray under high vibration and high load environments. This prevents the connection components from collapsing outward and the bolt fixing holes from cracking or breaking, thereby avoiding the collapse of the entire cable tray.

[0020] 2. This utility model uses multi-directional connecting plates and one-directional connecting plates for connection, replacing traditional molded connecting parts. Multi-directional connecting plates and one-directional connecting plates are highly versatile and can adapt to connection requirements at different angles, reducing the number of molds and production costs. Multi-directional connecting plates and one-directional connecting plates are easy to install, reducing on-site installation time and labor costs, and improving overall production efficiency.

[0021] 3. The cable tray design of this utility model is flexible. It can achieve horizontal multi-directional, vertical multi-directional, and corner multi-directional connections through multi-directional connecting plates and unidirectional connecting plates. It is suitable for cable wiring needs in different scenarios. In particular, the horizontal variable diameter straight cable tray and the bidirectional bend cable tray can adjust the variable diameter and angle according to actual needs to meet the multi-layer cable tray layout requirements in special environments such as offshore oil drilling platforms, thereby improving the applicability and flexibility of the cable tray system.

The E-shaped steel 8 of the first side plate 71 and the E-shaped steel 8 of the second side plate 72 are arranged with their straight plates facing each other. A number of crossbars 37 are arranged between the first side plate 71 and the second side plate 72. The crossbars 37 are located at the straight plate position of the E-shaped steel 8. The two ends of the crossbars 37 are inserted into the mounting grooves 22 of the E-shaped steel 8.

The E-shaped steel curved plates are composed of several E-shaped steel inclined plates, which are horizontally inclined and are inserted into the rectangular cavity 21 of the adjacent E-shaped steel inclined plates through a multi-directional connecting plate 5. Bolts pass through the E-shaped steel reinforcing plate 17 and the vertical... The straight plate 16 and the first connecting plate 27 and the second connecting plate 28 of the multi-directional connecting plate 5 are fixed together by fixing holes to form an E-shaped steel 8 curved plate with a certain angle horizontally set.

The second external threaded rod of the screw connector 15 is not set on the vertical plate 16 of the inclined plate of the E-shaped steel 8 in the first side plate 25 and the second side plate 26. A third-party tube 14 is installed on the inclined plate of the E-shaped steel 8 in the first side plate 25 and the second side plate 26 through a through-hole 24. Both ends of the third-party tube 14 are beveled, and the upper and lower flat plates at both ends are provided with mounting holes 221 for bolts to the inclined plates of the E-shaped steel 8 in the first side plate 25 and the second side plate 26.

The beveled ends of the third-party tube 14 are fitted against the inner side of the vertical plate 16 of the inclined plates of the E-shaped steel 8, and bolts pass through the central hole of the inclined plates of the E-shaped steel 8. Plate 19, lower plate 20, and third square tube 14 are fixed together; the second square tube 13 is arranged parallel between the horizontally arranged E-shaped steel 8 straight plate of the first side plate 25 and the horizontally arranged E-shaped steel 8 straight plate of the second side plate 26, and the two ends of the second square tube 13 are horizontally embedded in the mounting grooves 22 of the horizontally arranged E-shaped steel 8 straight plate and E-shaped steel 8 inclined plate of the first side plate 25 and the second side plate 26, and are fixed by bolts through the middle plate 19 and lower plate 20 of the E-shaped steel 8 inclined plate and the horizontally arranged E-shaped steel 8 straight plate in the first side plate 25 and the second side plate 26, forming a 90° trumpet-shaped assembly 305;

[0057] The horizontal tee cable tray 303 includes a first side plate 71, an assembly 305, crossbars 37, fixing pins 6, and nut sleeves 153. One side is the first side plate 71, which is a straight side plate 9 of E-shaped steel 8. The other side is the assembly 305. The E-shaped steel 8 of the first side plate 71 and the straight E-shaped steel 8 of the assembly 305 face each other. Multiple crossbars 37 are located between the first side plate 71 and the assembly 305. The crossbars 37, located between the straight E-shaped steel 8 of the first side plate 71 and the assembly 305, have both ends inserted into the mounting grooves 22 of the E-shaped steel 8 of the first side plate 71 and the assembly 305. The first square tube 12 of the crossbar 37 passes through the reinforcing plate of the E-shaped steel 8. The second external threaded rod 152 of the screw connector 15 of the rectangular hole 23 and the crossbar 37 passes through the round hole 24 of the vertical plate 16 of the E-shaped steel 8; and is first fixed by the nut sleeve 153 on the outside of the straight plate of the E-shaped steel 8 horizontally arranged in the first side plate 71 and the assembly 305 with the second external threaded rod 152 of the screw connector 15 at both ends of the multiple crossbars 37; and is second fixed by the fixing pin 6 passing through the middle plate 19, the lower plate 20 and the crossbar 37 of the straight plate of the E-shaped steel 8 horizontally arranged in the first side plate 71 and the assembly 305; the crossbar 37 of the second square tube 13 located in the first side plate 71 and the assembly 305, one end of the crossbar 37 is inserted into the E-shaped steel 8 of the first side plate 71. In the mounting groove 22 of the steel section 8, the first square tube 12 of the crossbar 37 passes through the rectangular hole 23 of the reinforcing plate 17 of the E-shaped steel 8 of the first side plate 71. The second external threaded rod 152 of the screw connector 15 of the crossbar 37 passes through the round hole 24 provided in the vertical plate 16 of the E-shaped steel 8 of the first side plate 71. The first fixation is achieved by the nut sleeve 153 on the outside of the E-shaped steel 8 of the first side plate 71 and the second external threaded rod 152 of the screw connector 15 of the crossbar 37. The second fixation is achieved by the fixing pin 6 passing through the middle plate 19, the lower plate 20 and the crossbar 37 of the E-shaped steel 8 on the first side. The second external threaded rod 152 of the screw connector 15 at the other end of the crossbar 37 passes through the middle position of the second square tube 13. The connecting holes of the vertical plate on the side are first fixed to the second external threaded rod 152 of the screw connector 15 of the multiple horizontal bars 37 on the outside of the second square tube 13 by the nut sleeve 153. Then, the fixing pin 6 passes through the mounting holes 221 of the upper and lower plates of the second square tube 13 and the second external threaded rod 152 of the screw connector 15 of the horizontal bar 37 for a second fixation. At the same time, the fixing pin 6 passes through the first square tube 12 of the horizontal bar 37 and the first external threaded rod of the screw connector 15 for fixation. This further strengthens the fixing strength between the horizontal bar 37 and the second square tube 13, and between the first square tube 12 of the horizontal bar 37 and the screw connector 15 in the horizontal bar 37, forming a horizontal three-way cable tray 303 with a 90° angle.

[0058] The horizontal four-way cable tray 304 includes two assemblies 305, crossbars 37, fixing pins 6, and nut sleeves 153. The two assemblies 305 have horizontally arranged E-shaped steel 8 plates facing each other. The crossbars 37 are located between the two assemblies 305. The crossbars 37, located between the horizontally arranged E-shaped steel 8 plates of the two assemblies 305, have both ends inserted into the mounting grooves 22 of the horizontally arranged E-shaped steel 8 plates of the two assemblies 305. The first square tube 12 of the crossbar 37 passes through the reinforcing plate of the E-shaped steel 8. The rectangular hole 23 of 17, the second external threaded rod 152 of the screw connector 15 of the crossbar 37 passes through the round hole 24 of the vertical plate 16 of the E-shaped steel 8; and is first fixed by the nut sleeve 153 on the outside of the horizontally arranged E-shaped steel 8 straight plate of the two assemblies 305 and the second external threaded rod 152 of the screw connector 15 at both ends of the multiple crossbars 37, and is then fixed a second time by the fixing pin 6 passing through the middle plate 19, the lower plate 20 and the crossbar 37 of the horizontally arranged E-shaped steel 8 straight plate of the two assemblies 305. The crossbar 37, located between the second square tubes 13 in the two assemblies 305, has its second external threaded rods 152 of the screw connectors 15 at both ends passing through the connection holes of the vertical plates on both sides of the middle position of the second square tubes 13 in the two assemblies 305. The crossbar 37 is initially fixed to the second external threaded rods 152 of the screw connectors 15 of the crossbar 37 on the outside of the second square tubes 13 in the two assemblies 305 by nut sleeves 153. A fixing pin 6 passes through the second external threaded rods 152 of the screw connectors 15 of the crossbar 37 in the two assemblies 305. The mounting holes 221 of the upper and lower plates of the two square tubes 13 and the second external threaded rod 152 of the screw connector 15 of the crossbar 37 are fixed for the second time. At the same time, the fixing pins 6 pass through the first square tubes 12 at both ends of the crossbar 37 and the first external threaded rod of the screw connector 15 to fix it. This further strengthens the fixing strength between the crossbar 37 and the second square tube 13, and between the first square tube 12 of the crossbar 37 and the screw connector 15 in the crossbar 37, forming a horizontal four-way cable tray 304 with a 90° angle.

[0059] like Figure 8As shown, the corner cable tray 3 also includes a cable tray with a bidirectional bend at an upward γ angle, comprising a first side plate 71, a second side plate 72, a crossbar 37, a fixing pin 6, and a nut sleeve 153. Both the first side plate 71 and the second side plate 72 are vertical, multi-directional open polygonal side plates 102. Both the first side plate 71 and the second side plate 72 are composed of straight E-shaped steel 8 plates, and are connected by a one-way connecting plate 38 inserted into the rectangular cavity 21 of the adjacent straight E-shaped steel 8 plates, and bolts pass through the E-shaped steel 8 plates vertically. The fixing holes of plate 16, reinforcing plate 17, and one-way connecting plate 38 are used to fix them, forming an upward-open polygonal first side plate 71 and second side plate 72 with an angle γ of 105°. The specific value of the angle γ can be changed according to the requirements, with a maximum of 135°. The length of the lower plate 20 of the E-shaped steel 8 straight plate of the first side plate 71 and the second side plate 72 is greater than the length of the upper plate 18, and the vertical plates 16 of the E-shaped steel 8 straight plate are located on the same vertical plane. The E-shaped steel 8 straight plates in the first and second side plates 71 and 72 are positioned on both sides of the multiple crossbars 37. The two ends of the crossbars 37 are inserted into the mounting grooves 22 of the E-shaped steel 8 straight plates. The first square tube 12 of the crossbars 37 passes through the rectangular hole 23 of the reinforcing plate 17 of the E-shaped steel 8 straight plate. The second external threaded rod 152 of the threaded connector 15 of the crossbars 37 passes through the round hole 24 of the vertical plate 16 of the E-shaped steel 8 straight plate. The crossbars 37 are connected to the multiple crossbars 37 on the outer sides of the first and second side plates 71 and 72 via nut sleeves 153. The second external threaded rod 152 of the end screw connector 15 is fixed for the first time, and fixed for the second time by the fixing pin 6 passing through the middle plate 19, lower plate 20 and crossbar 37 of the E-shaped steel 8 straight plate, forming a bidirectional cable tray with an upward bend at a γ angle. The γ angle of the bidirectional bend cable tray can also be set downward. The length of the lower plate 20 of the E-shaped steel 8 straight plate of the first side plate 71 and the second side plate 72 of the bidirectional bend cable tray with the γ angle set downward is less than the length of the upper plate 18.

[0060] like Figure 9As shown, the corner cable tray 3 also includes a cable tray with an upward bidirectional bend at an α angle, comprising a first side plate 71, a second side plate 72, a crossbar 37, a fixing pin 6, and a nut sleeve 153. Both the first side plate 71 and the second side plate 72 are vertical, multi-directional open polygonal side plates 102. Both the first side plate 71 and the second side plate 72 are composed of an E-shaped steel 8 inclined plate and E-shaped steel 8 straight plates distributed on both sides of the E-shaped steel 8 inclined plate. The vertical plate 16 of the E-shaped steel 8 inclined plate is parallel to the vertical plane and is inserted into the rectangular cavity 21 of the E-shaped steel 8 inclined plate and the E-shaped steel 8 straight plates on both sides through a one-way connecting plate 38, and is bolted through... The E-shaped steel 8 is fixed through the fixing holes of the reinforcing plate 17, vertical plate 16, and one-way connecting plate 38, forming an upward-open polygonal first side plate 71 and second side plate 72 with an angle α of 135°. The specific value of the angle α can be changed as needed, with a maximum of 175°. The length of the lower plate 20 of the E-shaped steel 8 inclined plate and the E-shaped steel 8 straight plates distributed on both sides of the inclined plate in the first side plate 71 and second side plate 72 is greater than the length of the upper plate 18. Furthermore, the vertical plates 16 of both the E-shaped steel 8 inclined plate and the E-shaped steel 8 straight plates distributed on both sides of the inclined plate are... On the same vertical plane, the E-shaped steel 8 in the first side plate 71 and the second side plate 72 are positioned on both sides of the plurality of crossbars 37. The two ends of the crossbars 37 are inserted into the mounting grooves 22 of the E-shaped steel 8. The first square tube 12 of the crossbar 37 passes through the rectangular hole 23 of the reinforcing plate 17 of the E-shaped steel 8. The second external threaded rod 152 of the screw connector 15 of the crossbar 37 passes through the round hole 24 of the vertical plate 16 of the E-shaped steel 8. The crossbars are initially fixed to the second external threaded rod 152 of the screw connector 15 at both ends of the plurality of crossbars 37 via a nut sleeve 153 on the outer side of the first side plate 71 and the second side plate 72, and secured by a fixing pin. The middle plate 19, lower plate 20, and crossbar 37 of the E-shaped steel 8 are used for a second fixation, forming a bidirectional cable tray with an upward bend at an α angle. The α angle of the bidirectional cable tray can also be set downwards. In the bidirectional cable tray with an upward bend, the lengths of the first side plate 71 and the lower plate 20 of the second side E-shaped steel 8 are greater than the length of the upper plate 18, while in the bidirectional cable tray with a downward bend, the lengths of the first side plate 71 and the lower plate 20 of the second side E-shaped steel 8 are less than the length of the upper plate 18. In practical applications, the two cannot be substituted for each other because they have upward and downward directions. Cable trays with bidirectional bends at an upward or downward γ angle and cable trays with bidirectional bends at an upward or downward α angle are mainly used in multi-layer cable trays to meet the spacing requirements between upper and lower cable trays.

[0061] like Figure 10As shown, the corner cable tray 3 also includes a 90° upward bidirectional bend cable tray, comprising a first side plate 71, a second side plate 72, a crossbar 37, a fixing pin 6, and a nut sleeve 153. Both the first side plate 71 and the second side plate 72 are vertical, multi-directional open polygonal side plates 102. Both the first side plate 71 and the second side plate 72 are composed of E-shaped steel 8 curved plates and E-shaped steel 8 straight plates distributed on both sides of the curved plates. The E-shaped steel 8 curved plates are composed of several E-shaped steel 8 inclined plates, and are connected by a one-way connecting plate 38 inserted into the rectangular cavity 21 of the adjacent E-shaped steel 8 inclined plates.
