Description

Technical Field

[0001] This invention relates to the field of metal cable trough roller resistance welding technology, specifically to a fireproof and sealed metal cable trough and its assembly and welding equipment for production. Background Technology

[0002] Metal cable trays are enclosed or semi-enclosed structural systems made of metal materials such as steel and aluminum. They are mainly used for the standardized laying, support, and protection of power and control cables. Their robust metal casing effectively blocks mechanical impacts from external objects and isolates the internal cables from water, dust, and corrosive gases. Simultaneously, their sealed metal structure provides excellent electromagnetic shielding, making them essential electrical tools for ensuring safe, neat, and easy-to-maintain building electrical wiring.

[0003] In the production process of metal cable trays, due to the requirements for fire resistance and other physical and chemical properties, corrosion-resistant galvanized metal sheets are usually selected for production. Welding is then carried out at the points and structures where welding is required. However, welding is usually carried out using arc welding, plasma welding, and laser welding. During the welding process, because the metal cable tray is relatively thin, using high power will damage the galvanized layer and cause deformation of the metal sheet due to the formation of a molten pool. Heat accumulation is difficult to dissipate, which will cause stress deformation inside the metal sheet, affecting its long-term use. In addition, the welding efficiency is low. Based on this, a fireproof and sealed metal cable tray and its assembly and welding equipment for production are proposed. Summary of the Invention

[0009] Preferably, the piston sealing rod is slidably installed on the inner side of the connecting groove, the top of the connecting groove is connected to the storage cavity, the support cylinder, the storage cavity and the connecting groove are filled with hydraulic oil, the electro-hydraulic telescopic column is fixedly installed on the top of the mounting platform by the bracket, and the specifications and positions of the second flexible roller resist welding group correspond to the roller resist welding ring and the first flexible roller resist welding group, respectively.

[0010] Preferably, a horizontal pipe is connected to the opposite side of the bottom end of the branch pipe. Several air outlets are opened on the opposite sides of the branch pipe and the horizontal pipe. The air outlets are evenly distributed in a rectangular linear pattern around the opposite sides of the branch pipe and the horizontal pipe. A connecting pipe is connected to the bottom end of the branch pipe. An air filter is connected to the bottom end of the connecting pipe.

[0015] Preferably, a smart control console is fixedly installed on one side of the top of the workbench.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. When the equipment is in use, the air-bag conveyor belt applies flexible pressure to the outside of the cable trough box. Then, with the power output of the support roller, the cable trough box enters the opposite side of the roller resistance welding ring and the second flexible roller resistance welding group. At this time, the electric control telescopic rod moves down, causing the mounting platform to move down and push out the second flexible roller resistance welding group. At the same time, the electric control telescopic column extends to cause the sliding platform to slide. The second flexible roller resistance welding group contacts the inner side of the inner shell and the bottom of the inner cavity. The outer side of the cable trough box is bonded by the second flexible roller resistance welding group, the first flexible roller resistance welding group, and the roller resistance welding ring, and rolling resistance welding is performed. The elastic structure design combined with the adjustable displacement position adjustment makes the pressure of each roller welding group adjustable, so that the inner shell, outer shell and honeycomb filling layer are bonded and welded by roller resistance welding, which improves welding efficiency and protection effect. 2. The cable trough rolls to the opposite side of the hollow filling conveyor belt. The heat-conducting liquid inside the hollow filling conveyor belt, together with the water flow through the guide pipe, promotes the formation of a heat conduction path between the guide pipe, the hollow metal roller, and the inside of the hollow filling conveyor belt. This reduces the heat dissipation of resistance welding, enhances heat dissipation, and reduces deformation. Through the heat conduction of the cable trough itself, the heat can be conducted away after resistance welding. The flexible protection also increases the structural protection effect. 3. During the resistance welding of the cable trough, some fumes will be generated due to the welding temperature. When the air pump is started, it will draw in the air filter. The airflow is introduced through the connecting pipe, and a negative pressure suction is formed inside the branch pipe. The airflow enters the branch pipe and horizontal pipe through the air outlet, forming a surrounding suction on the outside of the cable trough, which draws in the fumes. The fumes are then filtered inside the air filter through the horizontal pipe, branch pipe and connecting pipe, and finally discharged by the air pump. This increases the environmental protection function of the welding operation and enhances the environmental protection effect. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-9This invention provides a technical solution: a fireproof and sealed metal cable trough and its assembly and welding equipment, including a workbench 1 and a cable trough body 17. The workbench 1 has a through-slot 2 inside. Several support rollers 7 are rotatably mounted on the top and bottom of one end of the through-slot 2 via bearing brackets. An air-filled conveyor belt 8 is movably sleeved on the outside of the support rollers 7. A valve core 9 is installed on one side of the air-filled conveyor belt 8. Several hollow metal rollers 3 are rotatably mounted on the inside of the other end of the through-slot 2 via bearing support. A hollow filling conveyor belt 5 is sleeved on the outside of the hollow metal rollers 3. Sealed bearings 23 are sleeved inside both ends of the hollow metal rollers 3. A guide pipe 4 is sleeved on the inner side of the sealed bearings 23. An installation roller 25 is driven and installed in the middle of the through-slot 2. Several flexible elastic support fillers 26 are fixedly sleeved on the outside of the installation rollers 25. Roller welding rings 27 are fixedly sleeved on the outside of the flexible elastic support fillers 26. Four branch pipes 12 are fixedly installed on the top of the workbench 1. A top plate 15 is fixedly installed on the top of the branch pipe 12. Industrial vision sensor cameras 16 are installed on both sides of the bottom of the top plate 15. An electrically controlled telescopic rod 21 is fixedly installed on the bottom of the top plate 15. A storage cavity 31 is fixedly installed at the bottom of the electrically controlled telescopic rod 21. A mounting platform 24 is fixedly installed at the bottom of the storage cavity 31. Mounting grooves 32 are opened on both sides and the bottom of the mounting platform 24. Flexible roller solder resist assembly 33 is slidably installed inside the mounting groove 32. The opposite sides of the flexible roller solder resist assembly 33 are... A piston sealing rod 34 is connected via a bearing bracket. The mounting platform 24 has three connecting slots 35 inside. One end of the storage cavity 31 is connected to a support cylinder 29. A sealing piston 30 is sealed inside the support cylinder 29. An electro-hydraulic telescopic column 28 is connected to one side of the sealing piston 30. Electro-hydraulic telescopic columns 10 are fixedly installed on both sides of the top of the work platform 1. A sliding table 11 is fixedly installed on the opposite end of the electro-hydraulic telescopic column 10. A flexible roller anti-welding assembly 22 is rolled on the inner side of the sliding table 11.

[0029] The cable tray box 17 includes an inner shell 1701, a top sliding cover 1703, and an outer shell 1707. The top of both ends of the inner shell 1701 is fixedly installed with an outer folded sealing edge 1706. The bottom of both ends of the top sliding cover 1703 is bent into an outer concave sealing edge 1704. The inner shell 1701 and the outer shell 1707 are fixedly fitted with several openings 1702. Both ends of the inner shell 1701 and the outer shell 1707 are fixedly installed with outer sealing plates 1705. The opposite sides of the inner shell 1701 and the outer shell 1707 are installed with honeycomb filling layers 1708. The inner side of the honeycomb filling layer 1708 is provided with several through slots 1709.

[0030] The working principle of the above technical solution is as follows: During use, the operator places the spliced ​​and bent but unwelded cable trough box 17 on the opposite side of the support roller 7 and the air-filled conveyor belt 8. The guide pipe 4 is connected to the water cooling circulation equipment. At this time, gas is introduced into the air-filled conveyor belt 8 to generate flexible air pressure, which applies flexible pressure to the outside of the cable trough box 17, causing the inner shell layer 1701, the honeycomb filling layer 1708 and the outer shell layer 1707 to adhere. Then, with the power output of the support roller 7, the cable trough box 17 enters the opposite side of the roller weld resistance ring 27 and the flexible roller weld resistance assembly 33. At this time, the electrically controlled telescopic rod 21 moves down, causing the mounting platform 24 to move down, and then the electrically controlled hydraulic telescopic column 2... The extension of the piston 30 causes the sealing piston 30 to push the hydraulic oil inside the support cylinder 29, and the piston sealing rod 34 moves according to the communication effect, pushing out the flexible roller weld resistance assembly 33. At the same time, the electrically controlled telescopic column 10 extends to cause the sliding table 11 to slide, and the flexible roller weld resistance assembly 22 is attached to the outer side of the outer shell layer 1707 and the outer folded sealing edge 1706. The flexible roller weld resistance assembly 23 contacts the inner side of the inner shell layer 1701 and the bottom surface of the inner cavity. The flexible roller weld resistance assembly 23, the flexible roller weld resistance assembly 22, and the roller weld resistance ring 27 are used to attach the outer side of the cable tray box 17. The flexible roller weld resistance assembly 22 and the two flexible roller weld resistance assemblies 23 on both sides form a group. The bottom flexible roller weld resistance assembly 23 is attached to the outer side of the cable tray box 17. Roller resistance welding group 23 and roller resistance welding ring 27 form a group, constituting three groups of rolling resistance welding groups, and conductive resistance welding is controlled. The elastic force formed by the flexible elastic support filler 26 makes the roller resistance welding ring 27 fit against the outside of the cable trough box 17. Both flexible roller resistance welding group 23 and flexible roller resistance welding group 12 use the contact between the flexible elastic support filler 26 and the roller resistance welding ring 27 to make the outer side fit against the outside of the cable trough box 17 for rolling resistance welding. Because the inner shell layer 1701, outer shell layer 1707 and honeycomb filling layer 1708 are relatively thin, this elastic structure design, combined with adjustable displacement position adjustment, makes the pressure of each roller welding group adjustable. This allows the inner shell layer 1701, outer shell layer 1707, and honeycomb filling layer 1708 to be bonded together by roller resistance welding. As they roll to the opposite side of the hollow filling conveyor belt 5, the heat-conducting liquid inside the hollow filling conveyor belt 5 is conducted through the hollow filling conveyor belt 5 and, together with the flow pipe 4, facilitates the formation of a heat conduction path between the flow pipe 4, the hollow metal roller 3, and the hollow filling conveyor belt 5. This reduces the heat dissipation of the resistance welding, enhances the heat dissipation effect, and reduces deformation. Through the metal heat conduction of the cable trough box 17 itself, the heat can be conducted away after the resistance welding is completed, and the flexible protection increases the structural protection effect.

[0031] In another implementation scheme, such as Figures 1-9As shown, the hollow airbag conveyor belt 8 is filled with gas, the hollow filling conveyor belt 5 is filled with a heat-conducting working fluid, and the support roller 7 and the hollow airbag conveyor belt 8 are symmetrically and evenly distributed on both sides of the mounting roller 25 along with the hollow metal roller 3 and the hollow filling conveyor belt 5.

[0032] The gas inside the hollow airbag conveyor belt 8 is inflated and deflated through the valve core 9 to adjust the air pressure of the hollow airbag conveyor belt 8, thereby changing the flexible state of the hollow airbag conveyor belt 8. This allows for flexible compression and covering of the inner side of the cable trough box 17, facilitating structural positioning and conveying of the cable trough box 17 while reducing misalignment and ensuring stable welding and operation positions. The heat-conducting liquid inside the hollow filling conveyor belt 5 serves to store heat and transfer it through the heat conduction of the hollow filling conveyor belt 5. The hollow filling conveyor belt 5 is made of flexible and heat-conducting materials such as heat-conducting silicone pads and heat-conducting silicone cloth. Through transmission circulation, the heat is transferred to the hollow metal roller 3 and discharged through the liquid guided by the guide pipe 4, achieving efficient heat conduction circulation, reducing heat transfer and overflow, and increasing the protection effect.

[0033] In another implementation scheme, such as Figures 1-9 As shown, one end of the support roller 7 and the hollow metal roller 3 are both connected to the synchronous servo motor, and one end of the mounting roller 25 is connected to the servo motor through a transmission structure.

[0034] The support roller 7 and the hollow metal roller 3 are connected to the servo motor for transmission, which facilitates the transmission of power through the servo motor. This allows for the application of transmission force to the cable tray 17, synchronous transmission to reduce tension, ensure stable transmission, and increase structural stability. The transmission of the mounting roller 25 is synchronous with that of the support roller 7 and the hollow metal roller 3, which facilitates stable movement and coordinated operation of the structure.

[0035] In another implementation scheme, such as Figures 1-9 As shown, the piston sealing rod 34 is slidably installed on the inner side of the connecting groove 35. The top of the connecting groove 35 is connected to the storage cavity 31. The support cylinder 29, the storage cavity 31 and the connecting groove 35 are filled with hydraulic oil. The electro-hydraulic telescopic column 28 is fixedly installed on the top of the mounting platform 24 by the bracket. The specifications and positions of the flexible roller resist welding group 23 are respectively corresponding to the roller resist welding ring 27 and the flexible roller resist welding group 1 22.

[0036] The extension of the electro-hydraulic telescopic column 28 causes the sealing piston 30 to push the hydraulic oil inside the support cylinder 29, and the piston sealing rod 34 moves according to the communication effect, pushing out the flexible roller weld resistance assembly 33. At the same time, the extension of the electro-hydraulic telescopic column 10 causes the sliding table 11 to slide, and the flexible roller weld resistance assembly 22 is attached to the outer side of the outer shell layer 1707 and the outer folded sealing edge 1706. The flexible roller weld resistance assembly 33 is in contact with the inner side of the inner shell layer 1701 and the bottom surface of the inner cavity. The flexible roller weld resistance assembly 23, the flexible roller weld resistance assembly 22 and the roller weld resistance ring 27 are attached to the outer side of the cable trough box 17 to form a U-shape around the cable trough box 17, which facilitates the operation and achieves the function of adjustable displacement position.

[0037] In another implementation scheme, such as Figures 1-9 As shown, a horizontal pipe 14 is connected to the opposite side of the bottom end of the branch pipe 12. Several air outlets 13 are opened on the opposite sides of the branch pipe 12 and the horizontal pipe 14. The air outlets 13 are evenly distributed in a rectangular linear ring around the opposite sides of the branch pipe 12 and the horizontal pipe 14. A connecting pipe 20 is connected to the bottom end of the branch pipe 12. An air filter 18 is connected to the bottom end of the connecting pipe 20. The input end of the air filter 18 is connected to a vacuum pump 19 through a pipe. The air filter 18 and the vacuum pump 19 are both fixedly installed at the bottom of the workbench 1 by a bracket. The connecting pipe 20 is fixedly inserted through the workbench 1 and extends to the bottom of the workbench 1. The dimensions of the horizontal pipe 14 and the branch pipe 12 are larger than the dimensions of the support roller 7 and the hollow filling conveyor belt 5.

[0038] During resistance welding of the cable trough box 17, some fumes are generated due to the welding temperature. At this time, the air pump 19 is started, which creates a suction effect inside the air filter 18. The airflow is introduced through the connecting pipe 20, forming a negative pressure suction inside the branch pipe 12. The airflow enters the branch pipe 12 and the horizontal pipe 14 through the air outlet 13, forming a surrounding suction outside the cable trough box 17, which draws out the fumes. The fumes are then filtered inside the air filter 18 through the horizontal pipe 14, the branch pipe 12, and the connecting pipe 20, and finally discharged through the air pump 19. This increases the environmental protection function of the welding operation and enhances the environmental protection effect.

[0039] In another implementation scheme, such as Figures 1-9 As shown, the outer folded edge 1706 is wrapped around and attached to the outside of the outer shell layer 1707, the dimensions of the outer concave edge 1704 are adapted to the dimensions of the outer folded edge 1706, and the dimensions of the top sliding cover 1703 are adapted to the dimensions of the inner shell layer 1701 and the outer folded edge 1706.

[0040] The outer folded edge 1706 is part of the inner shell layer 1701 and is folded on the outside of the outer shell layer 1707, covering the top of the outer shell layer 1707 and the honeycomb filling layer 1708. The top sliding cover 1703 is folded to form a matching pile with the outer folded edge 1706 and the outer shell layer 1707, and can be slidably installed on the outside of the outer folded edge 1706 and the outer shell layer 1707, thereby realizing the formation of the structure and facilitating stability.

[0041] In another implementation scheme, such as Figures 1-9 As shown, the pipe hole 1702 is fixedly inserted through the inner shell layer 1701 and extends to the outside of the outer shell layer 1707. The pipe hole 1702 is linearly distributed inside the cable tray box 17.

[0042] The opening 1702 is an integral through-structure that is not connected to the internal honeycomb filling layer 1708. It serves to open holes for installation at the required locations. The opening is made as needed and, after being welded into the cable trough box body 17, it is cut to a specific size as required, so that the opening 1702 is distributed in the required locations. After cutting, the two ends of the cable trough box body 17 are sealed by welding the outer sealing plate 1705 to form a whole effect. Before welding the outer sealing plate 1705 after cutting, insulating and fireproof granular material is poured into the openings at both ends of the cable trough box body 17 and the slot of the through-hole 1709 to seal the honeycomb-shaped cavities of the honeycomb filling layer 1708. Finally, the two ends are sealed by the outer sealing plate 1705, thus achieving a perfect structure for production.

[0043] In another implementation scheme, such as Figures 1-9 As shown, the direction of the honeycomb opening of the honeycomb filling layer 1708 is parallel to that of the opening hole 1702, and the through slots 1709 are linearly and uniformly distributed on the opposite side of the honeycomb filling layer 1708. The interior of the honeycomb filling layer 1708 is filled with fireproof granular material.

[0044] The honeycomb filling layer 1708 enhances structural effectiveness and reduces material usage and weight. The internal honeycomb, filled with fire-retardant material, acts as a combination of aggregate and skeleton, providing fireproof and heat-insulating effects for the chamber. The two ends of the honeycomb filling layer 1708 are opposite to the inner shell layer 1701 and the outer shell layer 1707, allowing for conductive welding during the welding process through the contact points between the honeycomb filling layer 1708 and the inner shell layer 1701 and the outer shell layer 1707. This enables the structure to be internally resistance welded, ensuring relative structural stability and increasing the structural performance.

[0045] In another implementation scheme, such as Figures 1-9As shown, the dimensions of the flexible roller weld nugget assemblies 23 and 22 located on both sides of the mounting platform 24 are compatible with the dimensions of the inner shell 1701, outer shell 1707 and outer folded edge 1706. The dimensions of the flexible roller weld nugget assemblies 23 and 27 located at the bottom of the mounting platform 24 are compatible with the dimensions of the inner shell 1701 and outer shell 1707.

[0046] The flexible roller resistance welding assembly 33 and the flexible roller resistance welding assembly 22 on both sides perform extrusion resistance welding on both sides of the cable tray box 17. The outer side of the flexible roller resistance welding assembly 22 is adapted to the position of the outer shell layer 1707 and the outer folded sealing edge 1706, which can weld the outer folded sealing edge 1706 together during the rolling process without hindering the operation. The flexible roller resistance welding assembly 33 at the bottom is matched with the roller resistance welding ring 27 to perform contact welding on the bottom of the inner shell layer 1701 and the outer shell layer 1707, thereby making the structure roll stably, ensuring that the various structures fit together and welding, and increasing the use effect.

[0047] In another implementation scheme, such as Figures 1-7 As shown, a smart control console 6 is fixedly installed on one side of the top of the workbench 1.

[0048] The intelligent control console 6 is an intelligent control hardware and a built-in intelligent control system, which realizes intelligent control of welding production of various structures. It collects structural data and parameters through the industrial vision sensor camera 16, and adjusts the welding rate and power to increase the overall structural stability and ensure the structural performance. The input end of the intelligent control console 6 is connected to the output end of the industrial vision sensor camera 16 through the image processing module. The output end of the intelligent control console 6 is electrically connected to the input ends of the servo motor, the electrically controlled telescopic column 10, the air pump 19, the electrically controlled telescopic rod 21, the flexible roller resist welding group one 22, the roller resist welding ring 27, the electrically controlled hydraulic telescopic column 28, and the flexible roller resist welding group two 33 through the intelligent control unit, so as to control the operation of the equipment.

[0049] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
