Technical Field
[0001] This application relates to the technical field of docking devices, and in particular to a component docking device for steel structure engineering construction. Background Technology
[0002] Steel components refer to structural members made of angle steel, steel plates, channel steel, H-beams, or combinations thereof. They possess comprehensive advantages such as light weight, factory manufacturing, convenient installation, short construction period, good seismic performance, fast investment recovery, and low environmental pollution. The load-bearing capacity of steel components directly affects the construction quality of steel structure projects, thus playing an indispensable role in steel structure engineering construction and being widely used in industrial and civil buildings.
[0003] In existing steel structure construction, welding between steel components typically relies on specialized welding devices driven by electronic control systems. These devices automate the positioning, clamping, and welding operations of the components, improving the efficiency, accuracy, and automation level of the welding process. The electronic control system generally includes sensors, actuators, and a central controller, which assists in completing complex welding processes and ensures stable alignment of components during welding.
[0004] However, existing electrical control docking devices have significant drawbacks. First, the complexity of the electrical control system makes it difficult to quickly locate and troubleshoot equipment failures, often requiring professional intervention for repairs. This not only increases maintenance costs but can also lead to prolonged equipment downtime, delaying construction progress and the overall project schedule. Second, these devices are highly dependent on external power supplies. In the event of power outages or other emergencies at the construction site, they will completely lose their operational capability and be unable to perform docking tasks, introducing uncertainty and risk into the construction process and posing a potential threat to the smooth implementation of the project plan. These problems highlight the shortcomings of existing technology in terms of reliability and adaptability, necessitating improvements through technological innovation. Summary of the Invention
[0005] To reduce the dependence of the docking device on electricity, this application provides a component docking device for steel structure engineering construction.
[0006] This application provides a component docking device for steel structure engineering construction, which adopts the following technical solution: A component docking device for steel structure engineering construction, including a base; A tray is disposed on the top of the base. The tray includes a first tray and a second tray. The second tray is disposed on one side of the top of the base and is disposed opposite to the first tray. The first tray is slidably connected to the top of the base. A drive screw is rotatably connected to the base, and the drive screw is threadedly connected to the first support plate. A drive assembly is disposed on the base, and the drive assembly drives the drive screw to rotate. A two-way lead screw is rotatably connected to the support plate; The first clamping plate is slidably connected to the support plate and threadedly connected to the bidirectional lead screw. The first clamping plates are symmetrically arranged. A power assembly is disposed on the support plate, and the power assembly drives the bidirectional lead screw to rotate; The second clamping plate is symmetrically arranged and slidably connected to the opposite side of the first clamping plate. A control element is disposed on the first clamping plate, and the control element controls the up and down movement of the second clamping plate.
[0007] By adopting the above technical solution, the component docking device does not rely on the electrical control system, reducing the problems of difficult maintenance of electrical control system failures and reliance on external power supply, thus reducing maintenance costs and construction uncertainties. The drive component drives the drive screw to rotate, causing the first support plate to slide, realizing the initial position adjustment of the component. The power component drives the bidirectional screw to rotate, causing the first clamping plate to slide, realizing the lateral clamping of the component. The control component controls the up and down movement of the second clamping plate, which can clamp the component longitudinally, thereby realizing the stable docking of the component.
[0008] Optionally, the control component includes a control screw, which is rotatably connected to the first clamping plate and corresponds to it one-to-one, and the control screw is threadedly connected to the second clamping plate.
[0009] By adopting the above technical solution, a control screw that is threadedly connected to the second clamping plate is set on the first clamping plate. The second clamping plate can be moved up and down by rotating the control screw. This reduces the problem of existing electrical control docking devices relying on complex electrical control systems and external power supply, reduces the difficulty and cost of equipment failure maintenance, improves the reliability and adaptability of the device in special situations such as power outages, and ensures construction progress and project schedule.
[0010] Optionally, the second clamping plate includes a threaded sleeve, an insert plate, a plate body, and connecting bolts; The threaded sleeve is fitted onto the outer periphery of the control screw and is threadedly connected. The insert plate is disposed on the outer periphery sidewall of the threaded sleeve, and the plate body has an insertion groove for inserting the insert plate. The plate is located outside the first clamping plate, the connecting bolt passes through the plate, and the connecting bolt is threadedly connected to the insert plate.
[0011] By adopting the above technical solution, the second clamping plate of the component docking device is composed of a threaded sleeve, an insert plate, a plate body, and connecting bolts. The threaded sleeve is threadedly connected to the control screw, and the insert plate is inserted into the insertion slot of the plate body and fixed by the connecting bolts. This allows the second clamping plate structure to be flexibly assembled and disassembled, facilitating maintenance and component replacement. It reduces the possibility of increased maintenance costs and project delays due to equipment failures that are difficult to repair. At the same time, it does not rely on external power supply, thus improving the reliability and adaptability of the device.
[0012] Optionally, the power assembly includes a power worm gear and a power worm; The power worm gear is disposed on the outer periphery of the bidirectional lead screw and located outside the support plate. The power worm is rotatably connected to the side wall of the support plate, and the power worm and the power worm gear are threadedly connected.
[0013] By adopting the above technical solution, the power assembly adopts the structure of a power worm gear and a power worm, which can drive the bidirectional lead screw and thus control the sliding of the first clamping plate on the support plate. This reduces the problems of existing electrical control docking devices being difficult to maintain due to the complexity of the electrical control system and relying on external power, improves the reliability and adaptability of the component docking device, and ensures the construction progress.
[0014] Optionally, the drive assembly includes a drive worm gear and a drive worm. The drive worm gear is disposed on the outer periphery of the drive screw and located outside the base. The drive worm is rotatably connected to the side wall of the base, and the drive worm and the drive worm gear are threadedly connected.
[0015] By adopting the above technical solution, the component docking device uses a drive assembly consisting of a drive worm gear and a drive worm to drive the drive screw to rotate. This reduces the problem of existing electrical control docking devices relying on complex electrical control systems and external power supply, lowers maintenance costs, reduces the difficulty of equipment fault location and troubleshooting, reduces the possibility of long-term equipment downtime, improves the reliability and adaptability of the device at the construction site, reduces construction uncertainty and risk, and ensures the smooth implementation of the project plan.
[0016] Optionally, the second support plate is slidably connected to the top of the base, and a connecting screw is rotatably connected to the base. The connecting screw is threadedly connected to the second support plate, and the connecting screw is coaxially arranged with and fixedly connected to the drive screw. When the drive screw drives the connecting screw to rotate, the first support plate and the second support plate move closer to each other or further away from each other.
[0017] By adopting the above technical solution, the driving screw drives the coaxially connected connecting screw to rotate, so that the first and second support plates can move closer or further apart. This allows for adjustment of the spacing between steel components, facilitating docking operations. It also reduces the problems of difficult maintenance and reliance on external power in existing electrical control docking devices, and improves the reliability and adaptability of the docking device.
[0018] Optionally, a drive rack located below the support plate is provided on the side wall of the base; The end of the power worm gear is rotatably connected to a driving helical gear. The driving helical gear has a rotating groove around the power worm gear. The groove wall is uniformly provided with sliding teeth along the circumferential direction. The outer side wall of the power worm gear is provided with multiple connecting teeth. The sliding teeth mesh with the connecting teeth. When the connecting tooth abuts against the sliding tooth and the first clamping plates can approach each other, the sliding tooth drives the driving helical gear to rotate through the connecting tooth; When the connecting tooth abuts against the sliding tooth and the first clamping plates stop moving closer to each other, the sliding tooth is slidably connected to the connecting tooth. A connecting shaft is rotatably connected to the side wall of the pallet. A connecting helical gear and a transmission gear are provided on the connecting shaft. The driving helical gear meshes with the connecting helical gear, and the transmission gear meshes with the driving rack. When the connecting helical gear is slidably connected to the driving rack, it rotates in the same direction relative to the power worm gear.
[0019] By adopting the above technical solution, and utilizing structures such as drive racks, drive helical gears, transmission gears, and connecting helical gears, the power transmission and utilization during the process of the first clamping plates approaching each other are realized effectively. This makes the motion control of the device more coordinated, reduces the drawbacks of traditional electrical control docking devices that rely on complex electrical control systems, lowers maintenance costs and equipment failure risks, and improves the reliability and adaptability of the device in different construction environments.
[0020] Optionally, a control gear is rotatably sleeved on the outer periphery of the control screw, the control gear has a control groove extending in the circumferential direction, and drive teeth are evenly arranged in the circumferential direction on the groove wall away from the groove opening. Multiple transmission teeth are arranged on the outer periphery of the control screw, and the drive teeth mesh with the transmission teeth. When the drive tooth abuts against the transmission tooth and the second clamping plate can move downward, the drive tooth drives the control screw to rotate through the transmission tooth; When the driving tooth abuts against the transmission tooth and the second clamping plate stops moving downward, the driving tooth is slidably connected to the transmission tooth; The pallet is provided with control racks that correspond one-to-one with the first clamping plates. The control racks are slidably connected to the first clamping plates and mesh with the control gears of the corresponding first clamping plates.
[0021] By adopting the above technical solution, the downward movement of the second clamping plate is effectively controlled, and the possibility of the control screw continuing to rotate is reduced when the second clamping plate stops moving. At the same time, by using the cooperation of the control rack and control gear, the second clamping plates corresponding to multiple first clamping plates can be synchronously controlled, which improves the coordination and stability of the clamping operation of steel components.
[0022] Optionally, anti-slip layers are provided on the opposing sides of the first clamping plate.
[0023] By adopting the above technical solution, when components are joined, the anti-slip layer set on the opposite side of the second clamping plate can increase the friction with the components and improve the clamping stability of the components.
[0024] In summary, this application includes at least one of the following beneficial effects: 1. The use of a purely mechanical component docking device reduces the difficulty in quickly locating and eliminating faults caused by the complexity of the electrical control system, thereby reducing maintenance costs, minimizing equipment downtime, and ensuring construction progress; 2. It does not rely on external power supply and can still perform docking tasks normally in the event of power outages or other emergencies at the construction site, thus improving the reliability and adaptability of construction.

[0027] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.
[0028] This application discloses a component docking device for steel structure engineering construction.
[0029] This application mainly adopts a purely mechanical structure to achieve the connection of steel components, which achieves the effect of getting rid of dependence on electrical control and reducing maintenance costs. The following is a further detailed description of this application.
[0030] Example 1 See Figure 1 and Figure 2 The component docking device for steel structure engineering construction provided in this application includes a base 1, a support plate 2, a drive screw 11, a drive assembly 3, a bidirectional screw 23, a first clamping plate 4, a power assembly 5, a second clamping plate 6, and a control component. The base 1 is a cuboid structure. Two support plates 2 are arranged opposite each other on both sides of the top width of the base 1. The drive screw 11 is rotatably connected to the base 1 and threadedly connected to one of the support plates 2. The drive assembly 3 is disposed on the base 1 to drive the drive screw 11 to rotate. The bidirectional screw 23 is rotatably connected to the support plate 2. The first clamping plate 4 is slidably connected to the support plate 2 and threadedly connected to the bidirectional screw 23. The power assembly 5 is disposed on the support plate 2 to drive the bidirectional screw 23 to rotate. The second clamping plate 6 is symmetrically arranged and slidably connected vertically to the opposite side of the first clamping plate 4. The control component is disposed on the first clamping plate 4 to control the vertical movement of the second clamping plate 6. This achieves the effect of not relying on an electrical control system, being able to work stably in a power-free environment, and reducing maintenance costs. This is because a purely mechanical structure avoids the complexity of an electronic control system, reducing the probability of malfunctions and the difficulty of maintenance.
[0031] Specifically, the support plate 2 includes a first support plate 21 and a second support plate 22. The second support plate 22 is fixedly connected to one side of the top of the base 1, and the second support plate 22 is arranged opposite to the first support plate 21. The first support plate 21 is slidably connected to the top of the base 1. The first support plate 21 and the second support plate 22 can be made of high-strength steel plates to ensure that they can withstand the weight of the steel components. The sliding connection of the first support plate 21 can be achieved by opening a groove in the top of the base 1, and setting a slider at the bottom of the first support plate 21 that matches the groove. This structure is simple and provides stable sliding.
[0032] The drive screw 11 is rotatably connected to the base 1, and is threadedly connected to the slider at the bottom of the first support plate 21. The drive screw 11 can be made of high-strength alloy steel to ensure that it will not deform during rotation. The rotatable connection of the drive screw 11 can be achieved by installing a bearing in the base 1, with the drive screw 11 mounted in the bearing, which can reduce friction during rotation.
[0033] The drive assembly 3 includes a drive worm gear 31 and a drive worm 32. The drive worm gear 31 is fixedly connected to the outer peripheral side wall of the drive screw 11 and located outside the base 1. A support block is fixedly connected to the side wall of the base 1, and the drive worm 32 is rotatably connected to the support block. The drive worm 32 and the drive worm gear 31 are threadedly connected. The drive worm gear 31 and the drive worm 32 meet the self-locking parameters and can be made of copper alloy to improve their wear resistance. The rotation of the drive worm 32 can be achieved by a manual crank or by connecting to other manual power sources, such as a handwheel. When the drive worm 32 is rotated, the drive worm gear 31 is rotated through the threaded transmission, which in turn causes the drive screw 11 to rotate, driving the first support plate 21 to slide closer to or away from the second support plate 22 on the top of the base 1.
[0034] See Figure 1 and Figure 3 The bidirectional lead screw 23 is rotatably connected to the support plate 2 in a one-to-one correspondence. The bidirectional lead screw 23 can be made of stainless steel to reduce the possibility of rust. The rotatable connection of the bidirectional lead screw 23 can be achieved by setting a bearing seat on the support plate 2, and the bidirectional lead screw 23 is installed in the bearing seat.
[0035] The first clamping plate 4 is slidably connected to the support plate 2. Two sets of first clamping plates 4 are symmetrically arranged, each set corresponding to one support plate 2. Each set of first clamping plates 4 has two plates arranged symmetrically. The bidirectional lead screw 23 includes a forward-rotating part and a reverse-rotating part. The two first clamping plates 4 in the same set are threadedly connected to the forward-rotating part and the reverse-rotating part, respectively. The first clamping plates 4 can be made of cast iron to ensure sufficient strength. The sliding connection of the first clamping plates 4 can be achieved by opening a moving groove on the support plate 2 and fixing a matching moving block at the bottom of the first clamping plate 4, with the moving block slidingly connected to the moving groove. When the bidirectional lead screw 23 rotates, due to the characteristics of the bidirectional thread, the two first clamping plates 4 in the same set will move closer or further apart.
[0036] The power assembly 5 includes a power worm gear 51 and a power worm 52. The power worm gear 51 is located on the outer periphery of the bidirectional lead screw 23 and outside the support plate 2. The power worm 52 is rotatably connected to the side wall of the support plate 2, and the power worm 52 and the power worm gear 51 are threaded together. Both the power worm gear 51 and the power worm 52 can be made of copper alloy. The rotation of the power worm 52 can be manually operated, for example, by using a handle. Turning the handle drives the power worm 52 to rotate, which in turn causes the bidirectional lead screw 23 to rotate via the power worm gear 51.
[0037] There are two sets of second clamping plates 6, each set corresponding to one set of first clamping plates 4. Each set has two second clamping plates 6 arranged symmetrically, with the two second clamping plates 6 in the same set slidingly connected to the opposite side of the first clamping plate 4. Each second clamping plate 6 includes a threaded sleeve 61, an insert plate 62, a plate body 63, and a connecting bolt 64. The threaded sleeve 61 is fitted onto the outer periphery of the control screw 41, and the threaded sleeve 61 is threadedly connected to the control screw 41. The insert plate 62 is fixedly connected to the outer periphery of the threaded sleeve 61. The plate body 63 has an insertion groove 631 for the insert plate 62 to be inserted, and the plate body 63 is located outside the first clamping plate 4. The connecting bolt 64 passes through the plate body 63, and the connecting bolt 64 is threadedly connected to the insert plate 62. The threaded sleeve 61 can be made of plastic to reduce wear between it and the control screw 41. The insert plate 62 and the plate body 63 can be made of steel to ensure their strength. The insert plate 62 and the plate body 63 are fixed together by connecting bolts 64, which facilitates installation and disassembly.
[0038] The control component includes a control screw 41, which is rotatably connected to the first clamping plate 4 in a one-to-one correspondence. The control screw 41 is threadedly connected to the second clamping plate 6. The control screw 41 can be made of carbon steel. The rotatable connection of the control screw 41 can be achieved by installing a bearing on the first clamping plate 4, with the control screw 41 mounted inside the bearing, and the top of the control screw 41 protruding beyond the first clamping plate 4. When the control screw 41 rotates, it causes the second clamping plate 6 to move up and down via threaded transmission.
[0039] The first clamping plate 4 is provided with anti-slip layers 9 on opposite sides. The anti-slip layers 9 can be made of rubber, which can increase the friction between the anti-slip layers and the steel components and better clamp the steel components.
[0040] The implementation principle of the component docking device for steel structure engineering construction according to Embodiment 1 of this application is as follows: The component docking device in this embodiment adopts a purely mechanical structure, eliminating reliance on an electrical control system. The first support plate 21 and the first clamping plate 4 are moved manually via the drive component 3 and the power component 5, thereby positioning and initially clamping the steel component. Then, the second clamping plate 6 is moved up and down by the control components to further clamp the steel component. This purely mechanical structure reduces the complexity of the equipment, decreases the probability of failure, lowers maintenance costs, and allows for normal operation in environments without electricity, such as power outages, thus improving the stability and reliability of construction.
[0041] Example 2 See Figure 4 The difference between this embodiment and the previous embodiment is that: the second support plate 22 is slidably connected to the top of the base 1. The sliding connection between the second support plate 22 and the base 1 is achieved by a sliding groove and a sliding block. The sliding groove is opened at the top of the base 1, and the sliding block is fixed to the bottom of the second support plate 22, and the sliding block slides in the sliding groove. A connecting screw 12 is rotatably connected to the base 1. The connecting screw 12 is threadedly connected to the second support plate 22. The connecting screw 12 is coaxially arranged and fixedly connected to the driving screw 11.
[0042] See Figure 5 and Figure 6 A control gear 8 is rotatably mounted on the outer periphery of the control screw 41. The control gear 8 has a control groove 81 extending circumferentially. Multiple drive teeth 82 are evenly fixed circumferentially on the groove wall away from the groove opening of the control groove 81. Multiple transmission teeth 411 are fixedly connected to the outer periphery of the control screw 41, and the drive teeth 82 mesh with the transmission teeth 411.
[0043] See Figure 6 and Figure 7Each support plate 2 is fixedly connected to a set of control racks 42. Each set of control racks 42 has two racks, which are arranged opposite each other and staggered. Each control rack 42 corresponds to a first clamping plate 4. The control racks 42 are slidably connected to the moving blocks of the first clamping plate 4, and the control racks 42 mesh with the control gears 8 of the corresponding first clamping plates 4. The control gears 8 and control racks 42 can be made of aluminum alloy to reduce the overall weight. When the first clamping plate 4 moves, it drives the control gears 8 to slide on the control racks 42. At this time, the control gears 8 rotate. When the second clamping plate 6 can clamp the steel component downward, the drive gear 82 and the transmission gear 411 mesh to drive the control screw 41 to rotate, realizing the downward movement of the second clamping plate 6. When the second clamping plate 6 clamps the steel component until it stops moving downward, the drive gear 82 and the transmission gear 411 are slidably connected.
[0044] See Figure 8 and Figure 9 A drive rack 13 located below the support plate 2 is fixedly connected to the side wall of the base 1. A drive helical gear 7 is rotatably connected to the end of the power worm 52. The drive helical gear 7 has a rotating groove 71 surrounding the power worm 52. Sliding teeth 72 are evenly fixed circumferentially on the side wall of the rotating groove 71. Multiple connecting teeth 521 are fixedly connected to the outer side wall of the power worm 52, and the sliding teeth 72 mesh with the connecting teeth 521. A connecting shaft 25 is rotatably connected to the side wall of the support plate 2. A connecting helical gear 24 and a transmission gear 26 are fixedly connected to the outer side of the connecting shaft 25. The drive helical gear 7 meshes with the connecting helical gear 24, and the transmission gear 26 meshes with the drive rack 13. The drive rack 13, drive helical gear 7, transmission gear 26, and connecting helical gear 24 can be made of alloy steel to ensure their strength and wear resistance. When the power worm gear 52 rotates, it drives the drive helical gear 7 to rotate through the cooperation of the connecting gear 521 and the sliding gear 72. Then, through the meshing of the connecting helical gear 24 and the drive rack 13, the two support plates 2 can move closer or further apart.
[0045] The implementation principle of a component docking device for steel structure engineering construction according to Embodiment 2 of this application is as follows: By bringing the first support plate 21 and the second support plate 22 closer together, the relative first clamping plates 4 are brought closer together to clamp the steel component. At the same time, when the relative first clamping plates 4 are brought closer together, the second clamping plate 6 can move downward to clamp the steel component, greatly reducing the cumbersome clamping of the steel component.
[0046] 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.
