Description

Technical Field

[0001] This invention relates to the field of cable tray installation technology, and more particularly to a cable tray flipping device and its usage method. Background Technology

[0002] In urban rail vehicles, Type A aluminum alloy cars typically use cable trays under the car to store high and low voltage through-wires. The low-voltage cable trays are generally inverted and sealed, with cable tray covers. The entire cable tray is arranged inverted on the car body underframe. After wiring, the cable tray is sealed with a cable tray sealing cover. Previously, low-voltage cable trays were wired under the car using a bottom-view method. After wiring, the cable tray cover was installed while looking upwards. This bottom-view wiring method is difficult to operate, inefficient, and lacks standardization. Summary of the Invention

[0003] In response to the aforementioned technical problems, a wire trough flipping device and its usage method are provided.

[0004] The technical means employed in this invention are as follows:

[0005] A cable tray flipping device includes: a main crossbeam, a support device, a drive device, and multiple sets of fixing devices. The cable tray is fixed to the main crossbeam by the multiple sets of fixing devices. One end of the main crossbeam is rotatably connected to the support device, and the other end is connected to the drive device. The drive device is installed on the support device and is used to drive the main crossbeam to flip the cable tray. Pre-wiring splicing platforms are provided on both sides of the main crossbeam for cooperating with cable pre-laying.

[0006] Furthermore, the support device includes a non-transmission end shaft bracket, a non-transmission end shaft and fastening assembly, a transmission end shaft bracket and a transmission end shaft and fastening assembly. The non-transmission end shaft and fastening assembly includes a non-transmission end shaft and a fastening assembly. One side of the non-transmission end shaft is placed and fixed to the non-transmission end shaft bracket through a bearing mechanism, and the other side is fixedly connected to the end baffle on one side of the main crossbeam through the fastening assembly.

[0007] The transmission end shaft and fastening assembly include a transmission end shaft and a fastening assembly. One side of the transmission end shaft is fixedly connected to the end baffle on the other side of the main crossbeam through the fastening assembly, and the other side is connected to the drive device. The drive device is mounted on the transmission end shaft bracket.

[0008] Furthermore, the drive device includes a speed reducer motor, and a motor support and a shaft seat are welded to the top of the transmission end shaft bracket. The speed reducer motor is mounted on the motor support, and a spring pin is welded to the shaft seat. The speed reducer motor and the transmission end shaft are installed and fixed by the spring pin.

[0009] Furthermore, the fixing device includes a clamp, a baffle, and a set screw. Slide seats are welded on both sides of the main crossbeam. The clamp is slidably connected to the slide seat and can be adjusted laterally on the slide seat. The baffle is connected between the two clamps and is located in the vertical direction of the main crossbeam. The clamping connection between the clamp and the baffle presses and fixes the wire groove. The baffle is pressed and contacted with the top surface of the wire groove.

[0010] The main crossbeam is welded with set screw seats on both sides. The set screw is slidably connected to the set screw seat and can move laterally on the set screw seat. The inner side of the set screw is in tight contact with the side of the wire groove to fix the wire groove.

[0011] Furthermore, the clamping device includes a fixed plate, a fastening bolt assembly, a bent rod, an adjusting nut, a main handle, and a self-locking handle. The fixed plate is connected to the slide seats on both sides of the main crossbeam via the fastening bolt assembly. The bent rod is connected to the main handle, and the main handle is hinged to the fixed plate. Hooks are provided on both sides of the baffle, and the bent rod is sleeved on the hooks and pressed down and fixed using the main handle.

[0012] The left and right rotating shafts of the bent rod are equipped with adjusting nuts. The bent rod is connected to the main handle through the adjusting nuts. The clamping height of the bent rod can be adjusted by adjusting the tightness of the adjusting nuts. With a certain thickness of the baffle, the clamping height of the wire groove can be adjusted within a certain range using the clamping device.

[0013] The self-locking handle is connected to the fixed plate and has a spring mechanism. The fixed plate limits and locks the opening and closing state of the self-locking handle to ensure that the clamping device is securely and effectively locked.

[0014] Furthermore, the set screw adopts a threaded structure, including a screw rod, a disc sleeve, and a fixing bolt. The screw rod passes through the threaded hole of the set screw seat, and the external thread on the outer wall of the screw rod engages with the internal thread of the threaded hole of the set screw seat. The disc sleeve is fitted onto the head end of the screw rod that passes through the set screw seat, and the fixing bolt achieves a tight connection between the disc sleeve and the screw rod. The inner side of the disc sleeve is used to contact the side of the wire groove.

[0015] Furthermore, the pre-wiring splicing platform includes a first pre-wiring platform, at least one second pre-wiring platform, and a third pre-wiring platform. The first and third pre-wiring platforms are spliced ​​together and attached to the ends of the main crossbeam. The second pre-wiring platform is longitudinally spliced ​​behind the first and third pre-wiring platforms. The support device is located in the space below the first and third pre-wiring platforms.

[0016] Furthermore, each pre-wiring table has graduations on its surface; each pre-wiring table has a height adjustment nut and casters with brakes at the bottom for adjusting the table height, moving and placing it.

[0017] The main structure of each pre-wiring station uses an aluminum profile frame, and the inner tabletop of each pre-wiring station is made of wood. The wood tabletop is connected and fixed to the aluminum profile frame with screws. The outside of the wood tabletop is wrapped with a layer of stainless steel plate to form a stainless steel plate tabletop, with scales set on the upper surface of the stainless steel plate. The longitudinal sides of the stainless steel plate tabletop are fixed by welding stainless steel plate edge strips.

[0018] Furthermore, hangers are welded to both the upper and lower ends of the main crossbeam.

[0019] The present invention also provides a method of using the wire trough flipping device, comprising the following steps:

[0020] Step 1: Fix the cable tray to the main crossbeam in the forward direction using the fixing device, and use the pre-wiring splicing table to accurately pre-lay the extended cable bundles at both ends of the cable tray;

[0021] Step 2: After completing the wiring harness layout, install the cable tray cover and the junction box cover;

[0022] Step 3: By moving the pre-wiring splicing platform, use cable ties to bundle and fix the extension wires of the wire troughs on both sides to the tie steel square steel on both sides of the main crossbeam.

[0023] Step 4: Use the combination of clamps, baffles and top screws to fix the wire trough. Use the wire trough flipping device to flip the wire trough after pre-wiring. Open the spring pin connected to the motor drive shaft and use the main beam to hoist the flipped wire trough to the work area.

[0024] Compared with the prior art, the present invention has the following advantages:

[0025] 1. This invention enables pre-wiring of wire harnesses within the wire trough by allowing the trough to be rotated, replacing the traditional overhead wiring operation of undercarriage wiring. This improves production efficiency and simplifies production operations.

[0026] 2. This invention achieves precise cable pre-layout through the main crossbeam of the cable tray flipping device and the graduated splicing platforms on both sides. It also achieves cable tray flipping after wiring by using a top screw combination fixing structure to fix the cable tray and square steel reinforcing bars on both sides of the main crossbeam to fix the extended cable bundles on both sides of the cable tray.

[0027] 3. In this invention, the cable tray is fixed in the forward direction on the main crossbeam of the cable tray flipping device. Pre-wiring splicing tables are placed on both sides of the main crossbeam. The tables are marked with graduations. The cable tray cables are precisely wired using the flipping fixture and the pre-wiring tables. After the cable bundle arrangement is completed, the cable tray cover is installed, and the pre-wiring splicing tables are moved to bundle and fix the extended cable bundles on both sides of the cable tray to the tie steel square steel on both sides of the main crossbeam. The cable tray flipping device is used to flip the pre-wired cable tray as a whole (before the cable tray is flipped, it is fixed by a combination of clamping baffle and top screw fixing structure). The flipped cable tray is then hoisted to the working area using the main crossbeam.

[0028] Based on the above reasons, this invention can be widely applied in fields such as online slot installation. Attached Figure Description

[0069] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0070] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale.

[0074] This invention provides a cable tray flipping device and its usage method. The device achieves precise pre-layout of cables through the main crossbeam and the splicing platform with scales on both sides. The cable tray is fixed by a combination of top screws and square steel bars on both sides of the main crossbeam to fix the extension wire bundles on both sides of the cable tray, thereby achieving the flipping of the cable tray after wiring.

[0075] This invention fixes the cable trays upright on the main beam of the cable tray flipping device. Pre-wiring splicing tables with graduations are placed on both sides of the main beam. The flipping fixture and the pre-wiring tables are used to accurately wire the cables in the cable trays. After the cable bundles are arranged, the cable tray covers are installed, and the pre-wiring splicing tables are moved to bundle and fix the extended cable bundles on both sides of the cable trays to the tie bars on both sides of the main beam. The cable tray flipping device is used to flip the pre-wired cable trays as a whole (before flipping, the cable trays are fixed by a combination of clamping baffles and top screws). The flipped cable trays are then hoisted to the work area using the main beam.

[0076] This invention enables the wire harness in the wire trough to be pre-wired by flipping the wire trough, replacing the traditional upward-looking operation of wiring the wire trough under the machine, thus improving production efficiency and facilitating production operations.

[0077] The present invention's trough flipping device 1 consists of... Figure 2-5The trough 3 is composed of a main crossbeam 11, a non-transmission end shaft bracket 12, a non-transmission end shaft and fastening assembly 13, a clamp 14, a baffle 15, a set screw 16, a transmission end shaft bracket 17, and a transmission end shaft and fastening assembly 18. To ensure that the trough 3 can realize wiring and flipping, the main crossbeam 11 is first made for wiring of the trough 3, and rotating shafts and shaft brackets are set on both sides of the main crossbeam 11 for the trough 3 to rotate on the main crossbeam 11. The transmission end shaft bracket 17 is equipped with a reducer motor to realize the flipping function of the trough 3, and is installed and fixed to the transmission end shaft through a spring pin structure. The non-transmission end shaft on the other side is placed and fixed to the non-transmission end shaft bracket 12 through a bearing mechanism. To ensure the stability and safety of the trough 3 when flipping, a combination of clamp 14, baffle 15 and set screw 16 is used to fix the trough 3 in the horizontal and vertical directions (e.g., Figure 4 (As shown) Fixing is applied. In the transverse direction, it is fixed by welding set screw seats to both sides of the main crossbeam 11 and using set screws 16; in the vertical direction, it is fixed by welding slide seats to both sides of the main crossbeam 11 and using clamps 14 and baffles 15.

[0078] Because the set screw 16 uses a threaded structure, it can move within a certain range laterally in the welding set screw seat, which can meet the lateral fixing requirements of grooves of different widths. Figure 6 As shown.

[0079] Clamping device 14 Figure 7-8 As shown, it consists of a fixed plate 141, a fastening bolt assembly 142, a bent rod 143, an adjusting nut 144, a main handle 145, and a self-locking handle 146. The clamping device 14 uses the fastening bolt assembly 142 to fix the clamping device fixed plate 141 to the welded slide seats on both sides of the main crossbeam 11. The clamping device main handle 145 and the bent rod 143 clamp and fix the baffle 15. Figure 9 As shown. The bent rod 143 is fitted onto the hooks on both sides of the baffle 15 and pressed down to secure it using the main handle 145. The left and right rotating shafts of the bent rod 143 have adjustable nuts 144 on their upper and lower sides. The clamping height of the bent rod 143 can be adjusted by loosening or tightening the nuts 144. With a fixed thickness of the baffle 15, the clamping height of the wire groove 3 can be adjusted within a certain range using the clamping device 14. The clamping device 14 is also equipped with a self-locking handle 146 with a spring mechanism. The fixing plate 141 can limit and lock the opening and closing state of the self-locking handle 146, ensuring that the clamping device 14 is securely and effectively clamped.

[0080] The clamping device 14 is fixed by the slide seat. The clamping device 14 can be adjusted laterally within a certain range on the slide seat. When the clamping device 14 and the baffle 15 are used to fix the cable tray 3, interference between the low-voltage cable tray distribution box 31 and the baffle 15 can be effectively avoided. Figure 10 As shown.

[0081] This structure allows for the flipping and fixing of low-voltage cable trays 3 of various sizes, including cable trays 3 that are not in the characteristic position of the distribution box 31, and has versatility.

[0082] To ensure that the cable tray 3 can be transferred after being flipped, it needs to be hoisted. The main crossbeam 11 is used as a lifting device for overall hoisting. Lifting points are welded to both ends of the main crossbeam 11, and lifting seats 111 are installed at these points. This meets the hoisting requirements after flipping. Figure 11 As shown.

[0083] Because the cable is too long at the end of the cable tray 3, pre-wiring splicing platforms 2 are provided on both sides of the cable tray flipping device 1 to facilitate cable pre-wiring. The first pre-wiring platform 21 and the third pre-wiring platform 23, which are attached to the main crossbeam 11, can be opened, moved, and placed using bottom casters. The position and size of the platform support beams are designed according to the bottom shaft bracket dimensions to effectively avoid positional interference with the bottom shaft bracket. Two pre-wiring platforms 22 are longitudinally spliced ​​behind the splicing platforms 21 and 23 to ensure the cable pre-wiring length. Each pre-wiring platform has graduations on its surface for precise cable pre-wiring length measurement. Each pre-wiring platform has a height adjustment nut and casters with brakes at the bottom for height adjustment, movement, and placement. In actual use, the platform height should be adjusted to match the height of the main crossbeam 11. Figure 12 As shown.

[0084] Pre-wiring method: Fix the cable tray 3 upright on the main beam 11 of the cable tray flipping device 1. Use the pre-wiring splicing platform 2 to precisely pre-wire the extended cable bundles at both ends of the cable tray 3. After completing the cable bundle arrangement, install the cable tray cover and the junction box cover. By moving the pre-wiring splicing platform 2, use cable ties to back-bundle and fix the extended cable bundles of the cable tray 3 on both sides to the tie bars on both sides of the main beam 11. The cable wiring position diagram is shown below. Figure 13 , Figure 14 As shown. The wire trough 3 is fixed using a combination of clamping device 14, baffle 15, and set screw 16. The wire trough 3 is then flipped over using the wire trough flipping device 1. The spring pin connected to the motor drive shaft is opened, and the flipped wire trough 3 is hoisted to the work area using the main beam 11. The pre-wiring process flow diagram is shown below. Figure 15 As shown.

[0085] Example 1

[0086] First, fabricate the main crossbeam 11 according to the length and width of the cable tray 3, such as... Figure 16As shown, to ensure that the cable tray 3 can be smoothly placed on the main crossbeam 11 for wiring, the width of the main crossbeam 11 should be at least greater than the width of the mounting seats on both sides of the cable tray 3, and the length should be slightly greater than the length of the cable tray 3. The main crossbeam 11 can be made of Q235B material and should be welded with reinforcing square steel to ensure strength. End baffles are welded to both sides of the main crossbeam 11, and each end baffle has 4 mounting holes for the installation of the rotating shaft. Lifting seats 111 are welded to the upper and lower ends of the main crossbeam 11 for lifting the cable tray 3. The lifting seats 111 should meet certain strength requirements. The upper surface of the main crossbeam 11 is used to place the cable tray 3, and six sets of set screw seats with set screw thread holes and six sets of clamping slide seats are welded to both sides. The six sets of set screw seats and slide seats should be evenly distributed on both sides of the main crossbeam 11. The welding position of the set screw seats should ensure that the height of the set screw hole is less than the height of the cable tray 3 to ensure that the set screw 16 is in an effective state.

[0087] The set screw 16 consists of a screw 161 with a rotating handle, a disc sleeve 162 made of PVC material, and a fixing bolt 163, as follows: Figure 17 As shown. The screw 161 has a hole at its front end, with internal threads that match the external threads of the fixing bolt 163. The upper part of the screw 161 is also threaded, with the thread specification matching the thread specification of the set screw seat's threaded hole. The disc sleeve 162 has a hole large enough to allow the fixing bolt 163 to pass through. The set screw 161 is passed through the set screw seat's threaded hole, and the disc sleeve 162 is fitted into the screw 161 and secured with the fixing bolt 163. The depth of the disc sleeve 162 should ensure that after the set screw 161 reaches its innermost end, the external fixing bolt 163 can pass through the disc sleeve hole and the screw threaded hole for proper tightening. The length of the set screw 161 should allow for some adjustment, and the set screw disc sleeve 162 should have a certain thickness. The length of the fixing bolt 163 should ensure a proper tightening function with the threaded front end of the screw 161.

[0088] To ensure that the slide seat clamp 14 can move within a certain range, the length of each slide seat will be set according to the length of the groove 3 and the number of slides on both sides of the main crossbeam 11. The width of the slide groove of the slide seat should match the specification of the mounting bolt screw in the fastening bolt assembly 142 of the clamp 14. The baffle 15 can be made of square steel, with hooks welded on both sides. Figure 18 As shown, the total length should be slightly greater than the width of the wire trough 3. This ensures that the bent rods 143 of the clamps 14 on both sides of the wire trough 3 can be hooked onto the baffle 15. The clamps 14 can be made of 304 stainless steel. This ensures that the clamps 14 can perform their clamping function.

[0089] The non-drive end shaft adopts a welded structure of round tube and flange. The flange should have a certain thickness to ensure strength. The flange has an opening, and is fixed to the end baffle of the main crossbeam 11 using fastening components. The flange opening should correspond to the bolt diameter of the fastening components and the hole diameter of the end baffle of the main crossbeam 11. The non-drive end shaft bracket 12 is an integral welded steel structure, with a bearing structure welded to the top for placing the non-drive end shaft. Universal wheels are installed at the bottom for bracket movement, and bolt fixing devices are welded to both sides of the bottom to ensure the stability of the bracket. Figure 19-21 As shown.

[0090] The transmission shaft also employs a welded structure, with a socket welded to the non-flange end. The transmission shaft bracket 17 lacks a bearing structure; a motor support and shaft seat are welded to the top, with a spring pin welded to the shaft seat. The spring pin and shaft seat should correspond to the end structure and socket of the transmission shaft. The motor support should be compatible with the reducer motor. The bottom structure of the transmission shaft bracket 17 is the same as that of the non-transmission shaft bracket 12. Figure 22-24 As shown.

[0091] Based on the approximately 5-6 meter cable outlet length on each side of the A-type aluminum alloy cable tray, three pre-wiring platforms, each 2 meters long and 1 meter wide, with a height adjustment range of 880mm-920mm, are constructed on each side of the cable tray flipping device 1. The platforms closest to the end of the main crossbeam 11 of the pre-wiring cable tray flipping device 1 are two spliced ​​platforms, each 0.5 meters wide. All platform frames are made of aluminum profiles, with screws and nuts welded to the bottom for height adjustment. A square iron plate is welded below the screws, and holes in the iron plate are bolted to connect casters with brakes.

[0092] The tabletop is made of wood panel 24 covered with a layer of stainless steel sheet. The stainless steel sheet is 1.2mm thick, and the wood panel is 15mm thick. The wood panel 24 is connected and fixed to the aluminum frame with screws, and the aluminum frame is secured with bolts. The top dimension of the frame is slightly smaller than the length and width of the tabletop. The table is fabricated separately according to the dimensions of the two end supports to ensure that the side supports do not interfere with the supports after splicing. The stainless steel sheet is acid-etched to engrave the scale on both sides of the stainless steel tabletop. During engraving, the bending length at both ends of the stainless steel tabletop should be reserved to ensure that the scale is on the edge of the tabletop after bending. The smallest unit of the scale is 10mm, and the numbers are marked in 50mm increments. After acid etching, the stainless steel sheet is bent using a bending machine.
