Description

Technical Field

[0001] This invention belongs to the field of welding technology, specifically relating to an environmentally friendly welding slag recycling device. Background Technology

[0002] Currently, according to national ecological and environmental protection requirements, welding slag, as industrial solid waste, needs to be recycled during the welding process in steel structure welding construction, and then centrally processed according to solid waste treatment standards. Currently, welding slag is typically collected using a slag-collecting basin during steel structure welding. However, because existing basins require fixed installation with fasteners, their position cannot be flexibly adjusted according to changes in the welding location. This often results in the basin being too far from the actual welding position to accurately collect the slag, leading to slag spillage and affecting the construction environment. Furthermore, when the basin is full of slag and needs to be emptied, its own weight plus the weight of the collected slag far exceeds the capacity for manual operation, requiring the use of lifting equipment, further impacting ease of use and work efficiency. In view of the shortcomings of the existing technology, there is an urgent need to develop and improve a welding slag recycling solution. Summary of the Invention

[0003] This invention provides an environmentally friendly welding slag recycling device, which aims to improve the flexibility and efficiency of welding slag recycling operations during steel structure welding construction.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is: to provide an environmentally friendly welding slag recycling device, comprising: The suspension mechanism is used to detachably connect to the steel structure above the welding construction area. Two chains are horizontally spaced on the suspension mechanism, and the two ends of the chains hang down according to their own weight to form traction sections. The slag receiving box is open at the top and has an openable slag discharge gate at the bottom, which is used to connect to the slag discharge pipe. There is a traction mechanism on each of the opposite outer walls of the slag receiving box. The two traction mechanisms are respectively connected to the traction sections of the two chains, and the two traction mechanisms are connected by a hand drive assembly. The manual drive assembly is used to drive the two traction mechanisms to climb or fall synchronously along their respective traction sections, and the slag receiving box follows the two traction mechanisms to rise and fall synchronously.

[0005] In one possible implementation, the traction mechanism includes: Two crawling sprockets are rotatably connected to the top of the same side wall of the slag receiving box and are spaced apart. The two crawling sprockets are respectively meshed with the two traction sections. Two guide wheels are coaxially connected to the side wall of the slag receiving box and located between two crawling sprockets; Two traction sprockets are coaxially rotatably connected to the side wall of the slag receiving box and located below the guide wheel; The side plate is connected to the side wall of the slag receiving box and located on the side of the traction sprocket. It is used to drive the two traction sections to mesh with the two traction sprockets one by one. Among them, the two traction sections respectively pass over the top of one of the guide wheels on both sides of the guide wheel, and respectively engage with the corresponding traction sprocket on the same side of the traction sprocket; Both traction sprockets of the two traction mechanisms are connected to the manual drive assembly.

[0006] In some embodiments, the manual drive component includes: Two driven wheels are coaxially connected to the traction sprockets, corresponding to two traction mechanisms respectively; The drive shaft is rotatably connected to the bottom of the slag receiving box. Drive wheels are sleeved on both ends of the drive shaft. The two drive wheels correspond to the two driven wheels and are connected to each other for transmission. Two handwheels are respectively fitted and fixed to both ends of the drive shaft.

[0007] For example, the drive wheel and the driven wheel are meshing gears or chain sprockets, and the number of teeth on the driven wheel is at least twice the number of teeth on the drive wheel; the drive wheel is fixed between the two traction sprockets and has a diameter larger than that of the traction sprockets.

[0008] For example, a connecting seat is provided on the side of the side plate away from the traction sprocket. The connecting seat is rotatably connected to the side wall of the slag receiving box. A locking element is provided at one end of the connecting seat. The locking element is used to connect to the side wall of the slag receiving box to lock the rotational freedom of the connecting seat.

[0009] In one possible implementation, the locking element includes: The operating handle is fixed at one end to the connecting seat and extends parallel to the side wall of the slag receiving box at the other end. The screw is vertically inserted through the lugs on the side wall of the slag receiving box, and two lock nuts are screwed onto the screw, which are located on both sides of the lugs. The connecting rod is hinged at one end to the extension of the operating handle and at the other end to the end of the screw.

[0010] For example, the suspension mechanism includes: The hanging rail is horizontally set above the welding construction area and is detachably connected to the steel structure. An active trolley is slidably connected to a hanging rail and has an operating end that is suspended to the side of the slag receiving box; The follower trolley is slidably connected to the hanging rail and connected to the active trolley via a tie rod; Both the active pulley and the follower pulley are equipped with suspension points for hanging the chain.

[0011] In some embodiments, the active troop includes: The carriage has two sets of rollers arranged opposite each other. The two sets of rollers work together to clamp the hanging rail and roll on the hanging rail respectively. The bottom of the carriage is equipped with a load-bearing shaft as a lifting point. The drive sprocket is rotatably connected to the side of the carriage away from the steel structure and is connected to a set of rollers for transmission. The guide chain is fitted onto the drive sprocket and meshes with it. The guide chain hangs by its own weight on the side of the slag receiving box to form the operating end.

[0012] For example, a drive gear is fitted onto the axle of the drive sprocket, and a set of rollers includes two wheel bodies spaced apart, each wheel body having a driven gear coaxially mounted on it that meshes with the drive gear.

[0013] For example, at least two electro-permanent magnets are spaced apart along the axial direction of the suspension rail, and the electro-permanent magnets are used to magnetically connect the steel structure.

[0014] The beneficial effects of the welding slag environmental protection recycling device provided by this invention are as follows: Compared with the prior art, the welding slag environmental protection recycling device of this invention utilizes a suspension mechanism connected to a steel structure above the welding construction area to suspend two chains. The slag collection box is connected to the traction sections formed at both ends of the chains through traction mechanisms set on its opposite sides. Thus, the slag collection box can be suspended at a suitable height below the welding construction area by means of the connection between the traction sections and the chains. When the welding operation in the welding construction area adopts bottom-up welding, the two traction mechanisms can be driven synchronously to climb along their respective connected traction sections by a hand drive component connected to the two traction mechanisms, so that the slag collection box can be flexibly adjusted upward as the welding position rises. If the welding operation adopts a top-down welding path, the two traction mechanisms can be driven back along their respective corresponding traction sections by a hand drive component, so that the slag collection box can be flexibly adjusted downward as the welding position lowers. Therefore, the height of the slag collection box can be flexibly adjusted according to the change of welding height by operating the manual drive component. This not only saves time and effort, but also ensures that the slag collection box is always at a suitable height below the welding position. This ensures that all welding slag falls into the slag collection box during the welding operation, avoiding slag spillage and affecting the construction environment. Compared with the traditional method of collecting welding slag with a fire basin, this method improves the flexibility and efficiency of welding slag recycling operations.

[0015] Once the slag receiving box is full of welding slag, simply connect a slag discharge pipe extending to the welding slag collection area to the slag discharge gate. After opening the slag discharge gate, the welding slag in the receiving box will slide down to the welding slag collection area by its own weight, without the need for lifting tools to disassemble and dump the receiving box. This further improves the flexibility and convenience of welding slag recycling operations and increases construction efficiency. Attached Figure Description

[0018] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0019] It should be noted that when an element is referred to as being "set on" or "connected to" another element, it can be directly on or indirectly on the other element. It should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0020] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0021] Please refer to the following: Figures 1 to 9 The present invention will now describe the environmentally friendly welding slag recycling device. The device includes a suspension mechanism 10 and a slag receiving box 30. The suspension mechanism 10 is detachably connected to a steel structure 60 above the welding construction area. Two chains 20 are horizontally spaced on the suspension mechanism 10, with each end of the chain 20 hanging down under its own weight to form a traction section 200. The top of the slag receiving box 30 is open, and the bottom is equipped with an openable slag discharge gate 31 for connecting to a slag discharge pipe. A traction mechanism 40 is provided on each of the opposite outer walls of the slag receiving box 30. The two traction mechanisms 40 are respectively connected to the traction sections 200 of the two chains 20, and are connected via a hand-drive assembly 50. The hand-drive assembly 50 drives the two traction mechanisms 40 to synchronously climb or fall along their respective traction sections 200, and the slag receiving box 30 rises and falls synchronously with the two traction mechanisms 40.

[0022] It should be noted that the welding slag environmental recycling device provided in this embodiment adopts the manual operation of the hand drive component 50 to adjust the height of the slag receiving box 30. This avoids the increase in self-weight caused by the electric drive component, and meets the lightweight requirements to the greatest extent. In addition, during the welding construction of the steel structure 60, the slag receiving box 30 is close to the welding construction area. Therefore, the hand drive component 50 is within the controllable range of the welding operator, making the operation very convenient.

[0023] In this embodiment, the chain 20 is a structure formed by connecting circular or elliptical rings. The corresponding traction mechanism 40 has a sprocket that matches the pitch and chain hole of the chain 20. Thus, the two ends of the two chains 20 hanging down by their own weight form a flexible track that allows the traction mechanism 40 to climb and fall. At the same time, in order to ensure the smooth lifting of the slag receiving box 30, the hand drive assembly 50 drives the two traction mechanisms 40 to move at the same time, thereby preventing the slag receiving box 30 from tilting.

[0024] Compared with the prior art, the welding slag environmental protection recycling device provided in this embodiment utilizes a suspension mechanism 10 connected to a steel structure 60 above the welding construction area to suspend two chains 20. The slag collection box 30 is connected to the traction sections 200 formed at both ends of the chains 20 via traction mechanisms 40 arranged on opposite sides of the traction mechanism 40. Thus, the slag collection box 30 can be suspended at a suitable height below the welding construction area by means of the connection between the traction sections 200 and the chains 20. When the welding operation in the welding construction area adopts bottom-up welding, the two traction mechanisms 40 can be driven synchronously to climb along their respective connected traction sections 200 by the hand drive assembly 50 connected to the two traction mechanisms 40, so that the slag collection box 30 can be flexibly adjusted upward as the welding position rises. If the welding operation adopts a top-down welding path, the two traction mechanisms 40 can be driven back along their respective corresponding traction sections 200 by the hand drive assembly 50, so that the slag collection box 30 can be flexibly adjusted downward as the welding position falls. Therefore, by operating the hand-drive component 50, the height of the slag collection box 30 can be flexibly adjusted according to the change in welding height. This not only saves time and effort, but also ensures that the slag collection box 30 is always at a suitable height below the welding position. This ensures that all welding slag falls into the slag collection box 30 during the welding operation, preventing welding slag from spilling and affecting the construction environment. Compared with the traditional method of collecting welding slag with a fire basin, this method improves the flexibility and efficiency of welding slag recycling operations.

[0025] When the slag receiving box 30 is full of welding slag, simply connect a slag discharge pipe extending to the welding slag collection area to the slag discharge gate 31. After opening the slag discharge gate 31, the welding slag in the slag receiving box 30 will slide down to the welding slag collection area by its own weight. There is no need to use hoisting tools to disassemble and dump the slag receiving box 30. This can further improve the flexibility and convenience of welding slag recycling operations and improve construction efficiency.

[0026] It should be noted that, as Figure 1As shown, the suspension mechanism 10 can be two lifting rings fixed to the steel structure 60 based on fasteners, with one lifting ring connected to the middle of each chain 20. To improve the connection convenience between the suspension mechanism 10 and the steel structure 60, two electro-permanent magnets 14 with lifting rings can be used as the suspension mechanism 10. (The electro-permanent magnets 14 change the internal magnetic circuit state by instantaneously energizing the electronic control system, thereby realizing "magnetic adsorption" and "demagnetization release". After adsorption, no continuous power supply is required, and it can still maintain a strong magnetic force after power is cut off, with extremely high safety.) The electro-permanent magnets 14 are magnetically fixed to the steel structure 60, and the chains 20 are connected to the lifting rings of the electro-permanent magnets 14.

[0027] It should be explained that in this embodiment, the bottom of the slag receiving box 30 adopts a conical bottom structure, and a slag discharge gate 31 is set at the center of the conical bottom, thereby ensuring that the welding slag in the slag receiving box 30 can automatically slide down and be discharged after the slag discharge gate 31 is opened.

[0028] Specifically, such as Figure 2 As shown, the slag discharge gate 31 includes a slag discharge pipe 311 and a gate 312. The slag discharge pipe 311 is fixed to the center of the conical bottom of the slag receiving box 30 and communicates with the inner cavity of the slag receiving box 30. The pipe wall of the slag discharge pipe 311 is provided with a slot, and the gate 312 is inserted into the slot to seal the inner hole of the slag discharge pipe 311. Under normal circumstances, the gate 312 is in the closed state to prevent slag leakage.

[0029] The gate 312 has a folded edge, and the wall of the slag discharge pipe 311 has a threaded rod that passes through the folded edge and is screwed with a wing nut. This ensures the stability of the gate 312 when it is inserted into the slot to seal the slag discharge pipe 311. When slag discharge is required, the slag drop pipe leading to the slag collection area on the ground is first connected and fixed to the slag discharge pipe 311. Then, the wing nut is unscrewed, the folded edge is fastened, and the gate 312 is pulled outward to open the slag discharge pipe 311. This allows the slag in the slag receiving box 30 to slide through the slag drop pipe into the slag collection area on the ground. There is no need to disassemble the slag receiving box 30 and use hoisting tools to dump the slag, thus improving operational flexibility and efficiency.

[0030] In some embodiments, see Figure 3The traction mechanism 40 includes two crawling sprockets 41, two guide wheels 42, two traction sprockets 43, and a side plate 44. The two crawling sprockets 41 are rotatably connected to the top of the same side wall of the slag receiving box 30 and are spaced apart. The two crawling sprockets 41 are respectively meshed with the two traction sections 200. The two guide wheels 42 are coaxially connected to the side wall of the slag receiving box 30 and are located between the two crawling sprockets 41. The two traction sprockets 43 are coaxially rotatably connected to the side wall of the slag receiving box 30 and are located between the two crawling sprockets 41. Below the guide wheel 42; the side plate 44 is connected to the side wall of the slag receiving box 30 and located on the side of the traction sprocket 43, used to drive the two traction sections 200 to mesh with the two traction sprockets 43 respectively; wherein, the two traction sections 200 respectively pass over the top of one of the guide wheels 42 on both sides of the guide wheel 42, and respectively mesh with the corresponding traction sprockets 43 on the same side of the traction sprockets 43; the traction sprockets 43 of the two traction mechanisms 40 are both connected to the hand drive assembly 50 for transmission.

[0031] To ensure the stability of the slag receiving box 30, two crawling sprockets 41 are located at the two side edges of the box wall of the slag receiving box 30, and two traction sections 200 of the same chain 20 extend from the outer edges of the two crawling sprockets 41 that are far apart from each other, around the bottom of the crawling sprockets 41 and above the guide wheel 42. This allows each of the four corners of the slag receiving box 30 to have a traction section 200 bearing force, thereby preventing the slag receiving box 30 from tilting due to imbalance of force.

[0032] The guide wheel 42 can be a grooved wheel, a smooth wheel, or a sprocket. In order to improve the relative motion stability between the traction section 200 and the guide wheel 42, the guide wheel 42 can preferably be a sprocket that matches the chain link pitch and chain hole of the chain 20. The guide wheel 42 serves two purposes: firstly, it allows the traction section 200 to bypass the bottom of the crawling sprocket 41, thereby increasing the wrap angle between the traction section 200 and the crawling sprocket 41 and improving the meshing reliability of the traction section 200 and the crawling sprocket 41; secondly, it allows the traction sections 200 on both sides to bypass their respective guide wheels 42 and form a downward extending path, enabling both traction sections 200 to form a meshing connection on the same side of the traction sprocket 43. This allows the two traction sections 200 to achieve relative motion in the same direction with their respective meshing crawling sprockets 41 as the hand-drive assembly 50 drives the two traction sprockets 43 to rotate in the same direction. This enables the two crawling sprockets 41 to climb or fall synchronously on their respective traction sections 200, ensuring the smooth lifting and lowering of the slag receiving box 30.

[0033] It should be understood that for the chain 20 with the ring link structure, the two adjacent links are vertically interlocked. The adjacent teeth of the sprocket form a chain groove for a single link to be flatly embedded, and the sprocket teeth can be embedded in the link holes. Therefore, after the traction segment 200 meshes with the traction sprocket 43, the link is within the outline of the traction sprocket 43. Since the traction segment 200 and the traction sprocket 43 have relatively few meshing teeth and lack constraint force, a side plate 44 is set on the side of the traction sprocket 43 to form a constraint force on the traction segment 200, thereby avoiding the risk of the traction sprocket 43 derailing and improving the reliability of the meshing connection between the traction sprocket 43 and the traction segment 200.

[0034] Please combine Figure 4 and Figure 5 To illustrate, taking the lifting of the slag receiving box 30 as an example, the hand-drive assembly 50 drives the first traction sprocket 431 and the second traction sprocket 432 to rotate counterclockwise together. At this time, the first guide wheel 421 rotates clockwise under the drive of the first traction section 201, and the first crawling sprocket 411 rotates counterclockwise to achieve the climbing action on the first traction section 201. At the same time, the second guide wheel 422 rotates counterclockwise under the drive of the second traction section 202, and the second crawling sprocket 412 rotates clockwise to achieve the climbing action on the second traction section 202.

[0035] Therefore, by using the two guide wheels 42 to form different extension paths corresponding to the two traction sections 200, it is possible to achieve synchronous crawling and falling of the two crawling sprockets 41 on their respective corresponding traction sections 200 when the two traction sections 200 are respectively wrapped around the edges of the two crawling sprockets 41 that are far apart from each other. This helps to increase the distance between the stress points of the slag receiving box 30, thereby improving the stability of the slag receiving box 30.

[0036] As an optional implementation of the aforementioned manual drive component 50, please refer to Figure 3 and Figure 5 The hand-driven assembly 50 includes two driven wheels 51, a drive shaft 52, and two handwheels 54. The two driven wheels 51 are coaxially connected to the traction sprockets 43, corresponding to the two traction mechanisms 40 respectively. The drive shaft 52 is rotatably connected to the bottom of the slag receiving box 30. Drive wheels 53 are respectively sleeved on both ends of the drive shaft 52. The two drive wheels 53 correspond one-to-one with the two driven wheels 51 and are connected in transmission. The two handwheels 54 are respectively sleeved and fixed on both ends of the drive shaft 52.

[0037] By rotating the handwheel 54, the two drive wheels 53 mounted on the drive shaft 52 are rotated, which in turn drive the two driven wheels 51 to rotate synchronously. Since the driven wheels 51 are fixed to the traction sprockets 43, the synchronous rotation of each traction sprocket 43 can be achieved, thereby realizing the synchronous movement between each traction sprocket 43 and its corresponding traction section 200, making the slag receiving box 30 rise and fall smoothly, and the operation is simple and convenient.

[0038] The purpose of setting two handwheels 54 here is to allow welding operators to select either handwheel 54 to adjust the height of the slag receiving box 30 according to the actual situation, thereby improving operational flexibility. Moreover, when there is a lot of welding slag in the slag receiving box 30 and the weight increases, both handwheels 54 can be turned at the same time to avoid insufficient force when operating with one hand, thereby further improving operational flexibility.

[0039] It should be noted that in this embodiment, please refer to... Figure 3 The driving wheel 53 and the driven wheel 51 are gears that mesh with each other or sprockets that drive a chain, and the number of teeth on the driven wheel 51 is at least twice the number of teeth on the driving wheel 53; the driving wheel 53 is fixed between two traction sprockets 43 and its diameter is larger than that of the traction sprockets 43.

[0040] Gear drive for the drive wheel 53 and driven wheel 51 results in a smaller footprint and a more compact structure, while chain drive offers greater flexibility in layout. Both methods are viable and have their advantages. Gear drive is preferred here, utilizing a transmission ratio of more than twice that of the drive wheel 53 and driven wheel 51 to reduce the effort required to operate the handwheel 54. Simultaneously, the diameter of the handwheel 54 should be as large as possible, ideally with its edge aligned with the edge of the slag receiving box 30. This further reduces the effort required to operate the handwheel 54.

[0041] The drive wheel 53 has a larger diameter than the traction sprocket 43 and is located between the two traction sprockets 43. This allows the drive wheel 53 to create a spatial separation between the two traction sprockets 43, thus preventing interference between the traction sections 200 that cooperate with the two traction sprockets 43 and affecting motion stability. (See also...) Figure 3 and Figure 6 When the edge of the drive wheel 53 extends beyond the boundary of the traction sprocket 43, considering that the side plate 44 is closer to the rim of the traction sprocket 43, a clearance groove 441 is provided on the side plate 44 for the rim of the drive wheel 53 to pass through, thereby avoiding motion interference between the drive wheel 53 and the side plate 44.

[0042] To prevent the slag receiving box 30 from falling due to reverse motion of the traction mechanism 40 caused by its increased weight, and to improve operational safety, please refer to [the relevant documentation]. Figure 3 and Figure 5The side plate 44, facing away from the traction sprocket 43, is provided with a connecting seat 45. The connecting seat 45 is rotatably connected to the side wall of the slag receiving box 30. One end of the connecting seat 45 is provided with a locking member 46, which is used to connect to the side wall of the slag receiving box 30 to lock the rotational freedom of the connecting seat 45. After the locking member 46 is unlocked, the side plate 44 can be driven to radially press against or release the traction sprocket 43 by swinging the connecting seat 45, thereby realizing the braking and releasing of the traction sprocket 43. The operation is simple and convenient and can improve the safety of operation.

[0043] Optionally, such as Figure 3 As shown, the locking component 46 includes an operating handle 461, a screw 462, and a connecting rod 464; one end of the operating handle 461 is fixed to the connecting seat 45, and the other end extends parallel to the side wall of the slag receiving box 30; the screw 462 is vertically inserted through the ear plate 33 provided on the side wall of the slag receiving box 30, and two lock nuts 463 respectively placed on both sides of the ear plate 33 are screwed onto the screw 462; one end of the connecting rod 464 is hinged to the extended end of the operating handle 461, and the other end is hinged to the end of the screw 462.

[0044] After the lock nut 463 is released, the operating handle 461 can swing freely up and down, thereby unlocking the rotational freedom of the connecting seat 45. This causes the side plate 44 to release the traction sprocket 43. At this time, the hand drive assembly 50 can be operated to drive the traction sprocket 43 to rotate, thereby adjusting the height of the slag receiving box 30. After the adjustment is in place, the screw 462 is driven to move by rotating the lock nut 463 again, which creates a traction force on the operating handle 461, thereby causing the side plate 44 to press against the rim of the traction sprocket 43 to achieve braking.

[0045] Considering that the swing of the operating handle 461 forms an arc-shaped trajectory in the axial direction of the screw 462, a connecting rod 464 is provided between the operating handle 461 and the screw 462. The smoothness of the linear motion of the screw 462 driving the swing of the operating handle 461 is ensured by the hinge at both ends of the connecting rod 464.

[0046] Considering the convenience of manual operation, the aforementioned lock nut 463 is a hand-turn lock nut 463 with a rubber sleeve.

[0047] Specifically, such as Figure 2 As shown, in order to avoid the traction mechanism 40 being exposed, protective covers 32 are provided on both sides of the slag receiving box 30. The protective cover 32 has an elongated hole for the operating handle 461 to pass through and swing up and down. The protective cover 32 is provided with the aforementioned ear plate 33 for the screw 462 to pass through.

[0048] For some possible implementations, please refer to [link / reference]. Figures 7 to 9The suspension mechanism 10 includes a hanging rail 11, an active trolley 12, and a follower trolley 13. The hanging rail 11 is horizontally positioned above the welding construction area and is detachably connected to the steel structure 60. The active trolley 12 is slidably connected to the hanging rail 11 and has an operating end that hangs to the side of the slag receiving box 30. The follower trolley 13 is slidably connected to the hanging rail 11 and is connected to the active trolley 12 via a tie rod 15. Both the active trolley 12 and the follower trolley 13 are provided with suspension points for suspending the chain 20.

[0049] The main consideration for setting up the hanging rail 11 is that, given the large width of the welding construction area, the slag collection box 30 needs to be moved laterally to align with the area below the welding position. The hanging rail 11 can specifically adopt an I-beam structure 60. The cooperation between the active trolley 12 and the follower trolley 13 and the hanging rail 11 is similar to the high-altitude trolley structure commonly used in the prior art, and no specific limitations are made here.

[0050] The purpose of setting up the active trolley 12 and the follower trolley 13 is to form two mutually spaced chain 20 lifting points, thereby avoiding the chain 20 from passing through the welding position and occupying the welding operation space. The operating end of the active trolley 12 is suspended on the side of the slag receiving box 30. The active trolley 12 is controlled to move along the lifting rail 11 by the operating end. The follower trolley moves synchronously with the active trolley 12 based on the traction or pushing of the pull rod 15. This realizes the adjustment of the lateral position of the slag receiving box 30. Compared with the case of simply having height adjustment capability, it can cover a larger working range without changing the position of the suspension mechanism 10, further improving the flexibility, convenience and efficiency of the welding construction operation.

[0051] As an optional implementation of the aforementioned active trolley 12, please refer to Figure 8 and Figure 9 The active trolley 12 includes a carriage 121, a drive sprocket 122, and a guide chain 123. Two sets of rollers 1211 are arranged opposite each other on the carriage 121. The two sets of rollers 1211 cooperate to clamp the lifting rail 11 and roll on the lifting rail 11 respectively. A load-bearing shaft 1212 is passed through the bottom of the carriage 121 as a lifting point. The drive sprocket 122 is rotatably connected to the side of the carriage 121 away from the steel structure 60 and is connected to one of the sets of rollers 1211. The guide chain 123 is sleeved on the drive sprocket 122 and meshes with the drive sprocket 122. The guide chain 123 hangs on the side of the slag receiving box 30 by its own weight to form an operating end.

[0052] For the I-shaped suspension rail 11, two sets of rollers 1211 arranged opposite to each other on the slide 121 can roll on the bottom flanges on both sides of the web of the suspension rail 11 respectively. At the same time, the rims of the two sets of rollers 1211 form lateral rolling on the bottom flanges of the suspension rail 11, thereby forming a connection structure in which the two sets of rollers 1211 clamp the suspension rail 11 and roll along the suspension rail 11. This can ensure smooth movement and reliable connection, and prevent derailment.

[0053] It should be noted that the connection structure between the follower trolley 13 and the hanging rail 11 can be the same as that of the carriage 121, which will not be elaborated further here.

[0054] The guide chain 123 is fitted onto the drive sprocket 122 and hangs down on the side of the slag receiving box 30. This prevents the guide chain 123 from blocking the path of the welding slag. When the slag receiving box 30 needs to be moved laterally, the drive sprocket 122 can be rotated by pulling the guide chain 123, thereby driving one set of rollers 1211 to rotate actively on the hanging rail 11, thereby driving the slide 121 to move. At the same time, the follower trolley 13 connected to the slide 121 by the pull rod 15 also moves synchronously with the slide 121. The operation is simple and convenient.

[0055] Specifically, such as Figure 8 and Figure 9 As shown, in this embodiment, a drive gear 124 is sleeved on the axle of the drive sprocket 122. A set of rollers 1211 includes two spaced-apart wheel bodies, each with a driven gear 125 coaxially mounted on it, meshing with the drive gear 124. When the drive sprocket 122 is rotated by the guide chain 123, the drive gear 124, which is fixed relative to the drive sprocket 122, drives the driven gears 125 on the two wheel bodies to rotate in the same direction. This causes the two wheel bodies to jointly roll against the suspension rail 11, achieving the movement of the trolley. The drive method is simple and compact. To reduce the force required to operate the guide chain 123, the number of teeth on the drive gear 124 is less than the number of teeth on the driven gear 125.

[0056] In some embodiments, please refer to Figure 7 The aforementioned hanging rail 11 is provided with at least two electro-permanent magnets 14 spaced apart along its axial direction. The electro-permanent magnets 14 are used to magnetically connect the steel structure 60. The magnetic connection of the steel structure 60 by the electro-permanent magnets 14 allows for convenient and flexible disassembly and relocation. At the same time, the attraction of the electro-permanent magnets 14 does not depend on the continuity of power supply (only power is consumed during charging / demagnetizing), which can ensure the magnetic attraction strength in the power-off state, making it safe and reliable.

[0057] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
