Description

Technical Field

[0001] This application relates to the field of cable trays, and in particular to a combined plate type cable tray and a method for laying cables and cable trays simultaneously. Background Technology

[0002] With the acceleration of urban construction and the increasing demands on electromechanical installation for "tall, large, comprehensive, and new" buildings, there are many electrical devices and power supply system circuits in buildings. Various power supply cables extend to end users in public spaces, especially cables laid in basement roofs and public corridors, which usually have large diameters.

[0003] In traditional construction methods, cable tray installation and cable laying are carried out in separate steps: first, the cable trays are installed, and then the cables are laid on them. Because cable trays are typically installed at a high altitude, and are not always straight but rather have undulations or corners, laying large-section cables on them is difficult and inefficient. Furthermore, the long distances the cables are dragged along the cable trays during laying can easily cause scratches. Summary of the Invention

[0004] To improve the problems of low efficiency and easy cable scratching caused by traditional cable laying methods, this application provides a combined plate cable tray and a method for laying cables and cable trays simultaneously.

[0005] The combined plate-type cable tray provided in this application adopts the following technical solution: A combined panel cable tray, comprising: Multiple U-shaped steel plate channels, each U-shaped steel plate channel including a base plate and side plates fixed to both sides of the base plate, are connected end to end to form a cable tray, and two adjacent U-shaped steel plate channels are hinged; when two adjacent U-shaped steel plate channels are connected and flush with each other, a gap is provided between them; A connecting mechanism is connected between the side plates of two adjacent U-shaped steel plate channels, and the connecting mechanism is provided with a first locking element for locking the connection angle between the two adjacent U-shaped steel plate channels; A fastening mechanism, provided on one or more of the U-shaped steel plate channels, is used to fix the cable to the U-shaped steel plate channels; Multiple bases are spaced apart below the cable tray, and each base is provided with a height-adjustable support frame; A multi-faceted prism-shaped drive shaft is rotatably mounted on each of the support frames, and the periphery of the multi-faceted prism-shaped drive shaft is in frictional engagement with the bottom surface of the base plate; A drive mechanism is used to drive the polygonal drive shaft to rotate, thereby transmitting the cable tray along a straight line.

[0006] Multiple U-shaped steel troughs are connected end-to-end to form a cable tray via a connecting mechanism. Then, a fastening mechanism secures the cables to the cable tray. The height of the support frame is adjusted, and the cable tray is placed on a polygonal drive shaft. A drive mechanism then rotates the polygonal drive shaft, transporting the cable tray in a straight line. The cables move synchronously with the cable tray, achieving simultaneous laying of the cable tray and cables. After the cable tray is laid to the predetermined position, a first locking element locks the connection angle between two adjacent U-shaped steel troughs, fixing the cable tray in its final shape. Finally, a hanger or other fixing device secures the cable tray to the building. Compared to the conventional construction method of installing the cable tray first and then laying the cables, this application enables simultaneous laying of the cable tray and cables, improving construction efficiency and eliminating the need to drag cables long distances along the cable tray, reducing cable wear and scratches.

[0007] Furthermore, the fastening mechanism includes a mounting base fixed to the upper surface of the base plate, the mounting base being provided with a mounting groove for accommodating the cable, a tightening bolt being threaded through one side wall of the mounting groove, and one end of the tightening bolt abutting against the cable.

[0008] Place the cable in the mounting slot, rotate the tightening bolt so that its end is pressed against the cable, thereby fixing the cable to the mounting base and securing the cable in the cable tray.

[0009] Furthermore, the connecting mechanism includes a first connecting arm fixed to one edge of the side plate and a second connecting arm fixed to an adjacent edge of the side plate, the first connecting arm being hinged to the second connecting arm, and the first locking member being used to lock the connection angle between the first connecting arm and the second connecting arm.

[0010] By adjusting the relative rotation of the first connecting arm and the second connecting arm, as well as the locking function of the first locking element, the connection angle between two adjacent U-shaped steel plate channels can be adjusted, thereby facilitating the adjustment of the bending angle of the cable tray. This allows the cable tray to be laid not only straight but also with varying heights to meet different construction needs.

[0011] Furthermore, the first connecting arm has a receiving groove for accommodating the second connecting arm, and the second connecting arm is rotatably connected to the first connecting arm by a bolt, and the first locking member is a nut threadedly connected to the bolt.

[0012] When the nut is not tightened to the bolt, the second connecting arm can swing in the receiving groove, thus adjusting the connection angle between the two U-shaped steel plate grooves. The upper and lower side walls of the receiving groove limit the swing of the second connecting arm, so that the connection angle between the two U-shaped steel plate grooves can only be adjusted within a certain range. This helps to prevent the U-shaped steel plate grooves from flipping over significantly during the adjustment process, thereby improving the efficiency of angle adjustment.

[0013] Furthermore, the support frame includes two vertical fixed columns fixed to the base and a sliding column slidably disposed on the fixed columns in a vertical direction. The polygonal prism-shaped transmission shaft is rotatably disposed between the two sliding columns. A second locking member is provided on the sliding column for locking the sliding column to the fixed column.

[0014] When it is necessary to adjust the height of the cable tray and cable laying, the sliding column is slid along the fixed column, and then the sliding column is locked to the fixed column by the second locking member. The height of the polygonal prism type drive shaft can be adjusted, thereby realizing the adjustment of the height of the cable tray and cable laying.

[0015] Furthermore, the sliding column is hollow, and the fixed column is slidably disposed in the cavity of the sliding column. The fixed column has a plurality of insertion holes spaced apart along the vertical direction. The second locking member is a pin that penetrates the side wall of the sliding column and is adapted to be inserted into the insertion hole. The sliding column is provided with fasteners for locking the pin.

[0016] By passing the pin through the sliding post and inserting it into the corresponding hole, and then locking the pin with the fastener, the sliding post can be locked to the fixed post.

[0017] Furthermore, the drive mechanism includes a motor mounted on the base and a drive gear connected to the output end of the motor. Both ends of the polygonal prism-shaped transmission shaft are coaxially fixed with driven gears. The drive gear and one of the driven gears mesh together to form a transmission chain. The support frame is provided with an adjustment mechanism for maintaining the tension of the transmission chain as the height of the support frame changes.

[0018] The motor drives the drive gear to rotate, and under the transmission of the transmission chain, the driven gear drives the multi-faceted prism-shaped transmission shaft to rotate. The cable laying height can be adjusted by adjusting the height of the support frame. During this process, the transmission chain is kept taut by the adjustment mechanism to prevent the transmission chain from loosening due to changes in the distance between the drive gear and the driven gear, so as to maintain effective transmission between the drive gear, the driven gear, and the transmission chain.

[0019] Furthermore, the adjustment mechanism includes two connecting rods disposed on the sliding column and an adjustment component for driving the two connecting rods to move closer or further apart in the horizontal direction. Each connecting rod is rotatably provided with an adjustment gear, and the two adjustment gears are respectively meshed on opposite sides of the transmission chain.

[0020] When the distance between the driving gear and the driven gear decreases, causing the transmission chain to loosen, the adjusting component drives the two connecting rods to move away from each other in the horizontal direction, causing the two adjusting gears to extend to both sides and tighten the transmission chain.

[0021] Furthermore, the adjustment assembly includes two linear drive members mounted on the sliding column. The output ends of the two linear drive members extend in opposite directions and are both horizontal. The output ends of the two linear drive members are respectively fixed to the corresponding connecting rods.

[0022] When the output ends of the two linear actuators extend simultaneously, they can drive the two connecting rods to move away from each other in the horizontal direction; when the output ends of the two linear actuators retract simultaneously, they can drive the two connecting rods to move closer to each other in the horizontal direction.

[0023] This application provides a method for synchronously laying cables and cable trays, which uses a combined plate-type cable tray and includes the following steps: Step 1: Connect multiple U-shaped steel plate channels end to end using a connecting mechanism to form a cable tray; Step 2: Secure the cable to the cable tray using the fastening mechanism; Step 3: Adjust the height of the support frame and place the cable tray on the polygonal drive shaft; Step 4: Drive the multi-faceted prism-shaped transmission shaft to rotate through the drive mechanism, so that the cable tray is transported in a straight line and the cable moves forward synchronously with the cable tray, thus realizing the synchronous laying of the cable tray and the cable. Step 5: Lock the connection angle between two adjacent U-shaped steel plate channels using the first locking component to fix the cable tray shape; Step 6: Secure the cable tray to the building.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. This application fixes the cable to the cable tray and drives the cable tray to transmit the cable through a multi-prism type drive shaft, which can realize the synchronous laying of the cable tray and the cable. This not only improves the construction efficiency, but also eliminates the need to drag the cable along the cable tray over long distances, reducing cable wear and scratches. 2. By setting up U-shaped steel plate channels, connecting mechanisms and first locking components, the connection angle between adjacent U-shaped steel plate channels can be adjusted, thereby facilitating the adjustment of the bending angle of the cable tray. This allows the cable tray to be laid not only straight but also with varying heights to meet different construction needs. 3. By setting up height-adjustable support frames, the laying height of the cable tray can be easily adjusted. Attached Figure Description

Detailed Implementation

[0027] The following is in conjunction with the appendix Figure 1-11 This application will be described in further detail.

[0028] Example 1 This application discloses a combined plate-type cable tray. (Refer to...) Figure 1 and Figure 2The combined plate type cable tray includes multiple U-shaped steel plate channels 1, which are connected end to end to form a cable tray. Adjacent U-shaped steel plate channels 1 are hinged together. Each U-shaped steel plate channel 1 includes a base plate 101 and side plates 102 fixed to both sides of the base plate 101. A connecting mechanism 2 is provided between the side plates 102 of adjacent U-shaped steel plate channels 1. The connecting mechanism 2 is equipped with a first locking element for locking the connection angle between adjacent U-shaped steel plate channels 1. When two adjacent U-shaped steel plate channels 1 are connected and flush, a gap is provided between them.

[0029] Reference Figure 1 and Figure 3 One or more U-shaped steel plate channels 1 are equipped with fastening mechanisms 3 for fixing cables 10 to the U-shaped steel plate channels 1. Multiple bases 5 are spaced apart below the cable tray, and each base 5 is equipped with a height-adjustable support frame 52; multiple casters 51 are installed at the bottom of the base 5.

[0030] Reference Figure 1 , Figure 3 and Figure 4 A polygonal prism-shaped drive shaft 4, preferably a regular hexagonal prism, is rotatably mounted on the top of the support frame 52. The periphery of the polygonal prism-shaped drive shaft 4 is in frictional engagement with the bottom surface of the base plate 101. To increase the friction between the polygonal prism-shaped drive shaft 4 and the base plate 101, rubber anti-slip pads can be installed on the periphery of the polygonal prism-shaped drive shaft 4 and the bottom surface of the base plate 101. Furthermore, the width of each side of the polygonal prism-shaped drive shaft 4 is not less than the distance between two adjacent U-shaped steel plate grooves 1. A drive mechanism is provided on the support frame 52 to drive the polygonal prism-shaped drive shaft 4 to rotate, thus transporting the cable tray along a straight line.

[0031] Multiple U-shaped steel troughs 1 are connected end to end by the connecting mechanism 2 to form a cable tray. Then, the cable 10 is fixed to the cable tray by the fastening mechanism 3. The height of the support frame 52 is adjusted to place the cable tray on the polygonal prism-shaped drive shaft 4. The drive mechanism then drives the polygonal prism-shaped drive shaft 4 to rotate, thus transporting the cable tray in a straight line. The cable 10 moves forward synchronously with the cable tray, achieving synchronous laying of the cable tray and the cable 10. During the transmission of the cable tray, a traction device can be used to pull the front end of the cable tray.

[0032] After the cable tray is laid to the predetermined position, the connection angle between two adjacent U-shaped steel plate grooves 1 is locked by the first locking member to fix the cable tray in shape. Finally, the cable tray is fixed to the building by the fixing device such as the hanger.

[0033] Compared to the conventional construction method of installing cable trays first and then laying cables, this application can realize the simultaneous laying of cable trays and cables, which not only improves construction efficiency, but also eliminates the need to drag cables along the cable trays over long distances, reducing cable wear and scratches.

[0034] To secure cable 10 to the U-shaped steel trough 1, refer to... Figure 5 The fastening mechanism 3 includes a mounting base 31 fixed to the upper surface of the base plate 101. One side of the mounting base 31 has a mounting groove 34 for accommodating the cable 10. A tightening bolt 32 is threaded through one side wall of the mounting groove 34, and one end of the tightening bolt 32 located within the mounting groove 34 abuts against the cable 10. To facilitate rotation of the tightening bolt 32, a screw block 33 is fixed to the end of the tightening bolt 32 away from the cable 10. The screw block 33 has anti-slip protrusions.

[0035] The cable 10 is placed in the mounting groove 34, and the tightening bolt 32 is rotated so that its end abuts against the cable 10, thereby fixing the cable 10 to the mounting base 31 and securing the cable 10 in the cable tray. To improve the stability of the tightening bolt 32 in fixing the cable 10, a rubber anti-slip pad can be installed at the end of the tightening bolt 32 that contacts the cable 10, thereby increasing the friction between the tightening bolt 32 and the cable 10.

[0036] Reference Figure 2 , Figure 6 and Figure 7 The connecting mechanism 2 includes a first connecting arm 21 fixed to the edge of one side plate 102 and a second connecting arm 22 fixed to the edge of an adjacent side plate 102. The first connecting arm 21 is hinged to the second connecting arm 22, and a first locking member is used to lock the connection angle between the first connecting arm 21 and the second connecting arm 22. Furthermore, the distance between the two U-shaped steel plate grooves 1 is less than the height of the side plate 102, thus limiting the adjustment range of the connection angle between the two U-shaped steel plate grooves 1.

[0037] In one implementation, reference Figure 6 and Figure 7 The first connecting arm 21 has a receiving groove 24 for accommodating the second connecting arm 22. The second connecting arm 22 is rotatably connected to the first connecting arm 21 by bolts. The first locking member is a nut threaded to the bolt (only the bolt hole 23 for the bolt to pass through is shown in the figure).

[0038] When the nut is not tightened to the bolt, the second connecting arm 22 can swing within the receiving groove 24, thus adjusting the connection angle between the two U-shaped steel plate grooves 1. The upper and lower side walls of the receiving groove 24 limit the swing of the second connecting arm 22, ensuring that the connection angle between the two U-shaped steel plate grooves 1 can only be adjusted within a certain range. This helps prevent the U-shaped steel plate grooves 1 from flipping significantly during adjustment, thereby improving the efficiency of angle adjustment. When the nut is tightened to the bolt, the connection angle between the two U-shaped steel plate grooves 1 is locked.

[0039] In another implementation, refer to Figure 8 and Figure 9 The second connecting arm 22 is directly rotatably connected to the first connecting arm 21 by bolts, and the first locking element is a nut that is threaded to the bolt.

[0040] When the nut is not tightened to the bolt, the first connecting arm 21 and the second connecting arm 22 can rotate relative to each other, thereby adjusting the connection angle between the two U-shaped steel plate grooves 1; when the nut is tightened to the bolt, the connection angle between the two U-shaped steel plate grooves 1 is locked.

[0041] Because the connection angle between two adjacent U-shaped steel plate channels 1 is adjustable, it is easy to adjust the bending angle of the cable tray, allowing the cable tray to be laid not only straight but also with varying heights (such as...). Figure 2 As shown in the figure, to meet different construction needs.

[0042] Reference Figure 3 and Figure 4 The support frame 52 includes two vertical fixed columns 521 fixed to the base 5 and a sliding column 522 slidably disposed on the fixed columns 521 in a vertical direction. The sliding column 522 is hollow, and the fixed columns 521 are slidably disposed in the cavity of the sliding column 522. A crossbar 523 is fixedly connected between the two sliding columns 522, and a rubber sleeve 524 is fitted on the crossbar 523 to facilitate the operator to hold the crossbar 523 and adjust the height of the support frame 52. A polygonal prism-shaped drive shaft 4 is rotatably disposed between the two sliding columns 522, and the end of the polygonal prism-shaped drive shaft 4 is rotatably connected to the top of the sliding column 522 through a bearing 53.

[0043] Reference Figure 3 and Figure 4 The sliding column 522 is provided with a second locking member for locking the sliding column 522 to the fixed column 521. Specifically, the fixed column 521 is provided with a plurality of insertion holes 54 at intervals along the vertical direction, and the second locking member is a pin (not shown in the figure) that penetrates the side wall of the sliding column 522 and is adapted to be inserted into the insertion hole 54.

[0044] To improve the stability of the latch, refer to Figure 10 and Figure 11 The sliding column 522 is equipped with a fastener for locking the pin; specifically, one end of the pin is fixed to a pin plate 55, and the fastener is a U-shaped elastic buckle 512. The sliding column 522 has a groove 511 for sliding one side arm of the elastic buckle 512. The pin is inserted into the insertion hole 54, and then the elastic buckle 512 is slid along the groove 511, so that one side arm of the elastic buckle 512 abuts against the pin plate 55, thereby clamping the pin plate 55 onto the sliding column 522.

[0045] Furthermore, refer to Figure 11A connecting rope 56 is connected between the pin plate 55 and the sliding column 522. The connecting rope 56 helps to prevent the pin plate 55 from falling off and being lost.

[0046] When it is necessary to adjust the height of the cable tray and the cable 10, slide the sliding column 522 along the fixed column 521, then insert the pin into the corresponding socket 54, and then lock the pin by the elastic buckle 512, thereby locking the position of the sliding column 522. The height of the multi-faceted drive shaft 4 can be adjusted, thereby realizing the adjustment of the height of the cable tray and the cable 10.

[0047] To drive the multi-prism type drive shaft 4 to rotate, refer to Figure 3 and Figure 4 The drive mechanism includes a motor 8 mounted on the base 5 and a drive gear 9 connected to the output end of the motor 8; both ends of the multi-prism type transmission shaft 4 are coaxially fixed with driven gears 6, and the drive gear 9 and one of the driven gears 6 mesh together with a transmission chain 7. The support frame 52 is provided with an adjustment mechanism for keeping the transmission chain 7 tensioned as the height of the support frame 52 changes.

[0048] Furthermore, refer to Figure 1 and Figure 3 The distance between the two driven gears 6 is adapted to the width of the U-shaped steel plate groove 1, and the radius of the driven gears 6 is greater than the height of the U-shaped steel plate groove 1. This helps to improve the stability of cable tray transmission.

[0049] The motor 8 drives the drive gear 9 to rotate, and under the transmission of the transmission chain 7, the driven gear 6 drives the polygonal prism-shaped transmission shaft 4 to rotate. The laying height of the cable 10 can be adjusted by adjusting the height of the support frame 52. During this process, the transmission chain 7 is kept taut by the adjustment mechanism to prevent the transmission chain 7 from becoming loose due to changes in the distance between the drive gear 9 and the driven gear 6, so as to maintain effective transmission between the drive gear 9, the driven gear 6, and the transmission chain 7.

[0050] To maintain tension in drive chain 7, refer to... Figure 11 The adjustment mechanism includes two connecting rods 59 mounted on the sliding column 522 and an adjustment component for driving the two connecting rods 59 to move closer or further apart in the horizontal direction. Each connecting rod 59 is rotatably mounted with an adjustment gear 510, and the two adjustment gears 510 are respectively meshed on opposite sides of the transmission chain 7.

[0051] Specifically, refer to Figure 11 A fixed plate 57 is fixedly connected to the sliding column 522. The adjustment assembly includes two linear drive members 58 installed on both sides of the fixed plate 57. The linear drive members 58 can be electric push rods or cylinders. The output ends of the two linear drive members 58 extend in opposite directions and are both horizontal. The output ends of the two linear drive members 58 are respectively fixedly connected to the corresponding connecting rods 59.

[0052] During the process of adjusting the height of the support frame 52, when the distance between the driving gear 9 and the driven gear 6 decreases and the transmission chain 7 becomes loose, the two linear drive members 58 drive the two connecting rods 59 to move away from each other in the horizontal direction, thereby causing the two adjusting gears 510 to extend to both sides and tension the transmission chain 7.

[0053] The implementation principle of a combined plate-type cable tray according to an embodiment of this application is as follows: Multiple U-shaped steel plate troughs 1 are connected end-to-end through a connecting mechanism 2 to form a cable tray. Then, cables 10 are fixed to the cable tray through a fastening mechanism 3. The height of the support frame 52 is adjusted, and during the adjustment process, the transmission chain 7 is kept taut through the adjusting mechanism. The cable tray is then placed on a polygonal prism-shaped transmission shaft 4. Subsequently, the driving mechanism drives the polygonal prism-shaped transmission shaft 4 to rotate, transmitting the cable tray in a straight line. Cables 10 move synchronously with the cable tray, achieving synchronous laying of the cable tray and cables 10. After the cable tray is laid to the predetermined position, the connection angle between two adjacent U-shaped steel plate troughs 1 is locked by a first locking member to fix the cable tray in shape. Finally, the cable tray is fixed to the building using a hanging bracket or other fixing device.

[0054] Compared to the conventional construction method of installing cable trays first and then laying cables, this application can realize the simultaneous laying of cable trays and cables, which not only improves construction efficiency, but also eliminates the need to drag cables along the cable trays over long distances, reducing cable wear and scratches.

[0055] Example 2 This application discloses a method for synchronously laying cables and cable trays. The combined plate type cable tray used is as described in Embodiment 1. The laying method includes the following steps: Step 1: Connect the first connecting arm 21 and the second connecting arm 22 with bolts and nuts, thereby connecting multiple U-shaped steel plate channels 1 end to end to form a cable tray; Step 2: Place the cable 10 in the mounting groove 34, rotate the tightening bolt 32 to fix the cable 10 to the mounting base 31, thereby fixing the cable 10 on the cable tray; Step 3: Adjust the height of the support frame 52, keep the transmission chain 7 taut through the adjustment mechanism, and place the cable tray on the polygonal prism-shaped transmission shaft 4; Step 4: Drive the multi-faceted prism-shaped transmission shaft 4 to rotate through the drive mechanism, so that the cable tray is transported in a straight line and the cable 10 moves forward synchronously with the cable tray, so as to realize the synchronous laying of the cable tray and the cable 10. Step 5: Tighten the nuts on the bolts between the first connecting arm 21 and the second connecting arm 22 to lock the connection angle between the two adjacent U-shaped steel plate grooves 1, so that the cable tray is shaped; Step 6: Secure the cable tray to the building using hanging brackets or other fixing devices.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.

A method for synchronously laying cables and cable trays, characterized in that: The combined plate type cable tray according to any one of claims 1-7 includes the following steps: Step 1: Connect multiple U-shaped steel plate channels end to end using a connecting mechanism to form a cable tray; Step 2: Secure the cable to the cable tray using the fastening mechanism; Step 3: Adjust the height of the support frame and place the cable tray on the polygonal drive shaft; Step 4: Drive the multi-faceted prism-shaped transmission shaft to rotate through the drive mechanism, so that the cable tray is transported in a straight line and the cable moves forward synchronously with the cable tray, thus realizing the synchronous laying of the cable tray and the cable. Step 5: Lock the connection angle between two adjacent U-shaped steel plate channels using the first locking component to fix the cable tray shape; Step 6: Secure the cable tray to the building.
