Description

Technical Field

[0001] This invention relates to the field of steel structure docking technology, and in particular to a high-altitude docking device suitable for the installation of large steel structures. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses, and other components made of shaped steel and steel plates. The characteristics of steel structures are: high strength, light weight, good overall rigidity, and strong resistance to deformation, making them particularly suitable for constructing large-span, super-high, and super-heavy buildings; good material homogeneity and isotropy, belonging to an ideal elastic body, best conforming to the basic assumptions of general engineering mechanics; good material plasticity and toughness, allowing for large deformation and excellent resistance to dynamic loads; short construction period; and a high degree of industrialization, enabling highly mechanized and specialized production.

[0003] Currently available high-altitude docking devices for large steel structure installations are often large in size and occupy a lot of space. They have a single docking trajectory for steel structures, and can only dock along the X-axis or Y-axis. After the device is installed, it is difficult to dock in a certain direction between the X-axis and Y-axis, and it cannot automatically position the steel structure for docking. The installation and docking efficiency is low. In addition, it cannot spray anti-rust liquid on steel structures that have been left unused for a long time before docking and installation, which is prone to corrosion. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art and to propose a high-altitude docking device suitable for the installation of large steel structures.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-altitude docking device suitable for the installation of large steel structures includes a base with an adjustment mechanism for docking.

The rope portion of the winding roller is fixedly connected to the first rod.

[0008] Furthermore, a one-way air inlet pipe and a one-way air outlet pipe are fixedly connected through the inner wall of the buffer airbag. The one-way air outlet pipe is fixedly connected to multiple telescopic sleeves. An electronic valve is provided inside the telescopic sleeves. Multiple return springs are installed inside the buffer airbag.

[0009] Furthermore, the adjustment mechanism includes two sets of support members symmetrically arranged on the top wall of the base. Each set of support members includes two support blocks. A first lead screw is rotatably connected through the inner wall of the two support blocks. A first nut is threadedly connected to the side wall of the first lead screw. A first slide rod is fixedly connected to the side wall of the first nut. A second lead screw is rotatably connected through the inner wall of the two sets of support blocks. A second nut is threadedly connected to the side wall of the second lead screw. A second slide rod is fixedly connected to the side wall of the second nut. A slide block is slidably connected through the side wall of the first slide rod. A drive component is installed on the base.

[0010] Furthermore, the driving component includes a drive motor fixedly connected to the base, a first one-way bearing fixedly connected to the output end of the drive motor, a drive gear fixedly connected to the outer ring of the first one-way bearing, a driven gear fixedly connected to the side wall of one of the first lead screws, the drive gear and the driven gear meshing with each other, the two first lead screws connected by a timing belt component, and the two second lead screws also connected by a timing belt component.

[0011] Furthermore, the inner ring of the first one-way bearing is fixedly connected to a second one-way bearing, the side wall of the second one-way bearing is provided with a rotating shaft, the side wall of the rotating shaft is fixedly connected to a first conical wheel, one end of the second lead screw is fixedly connected to a second conical wheel, and the first conical wheel and the second conical wheel are meshed together.

[0012] Furthermore, a first annular airbag is fixedly connected to the side wall of each first nut, and the other end of the first annular airbag is fixedly connected to the slide. A second annular airbag is fixedly connected to the side wall of each second nut, and the other end of the second annular airbag is fixedly connected to the slide.

[0013] Furthermore, a spraying frame is fixedly connected to the side wall of the bracket, and multiple spraying machines are fixedly connected to the bottom wall of the spraying frame. A liquid storage tank is fixedly connected to the inner wall of the base. A first one-way liquid inlet pipe and a first one-way liquid outlet pipe are fixedly connected through the inner wall of the first annular airbag.

Both the first one-way liquid inlet pipe and the second one-way liquid inlet pipe are fixedly connected to the liquid storage tank, and both the first one-way liquid outlet pipe and the second one-way liquid outlet pipe are fixedly connected to the spraying machine.

[0014] The present invention has the following advantages:

[0015] By setting up supports, multiple pressure rollers and a spraying machine, when high-altitude docking of steel structures is required, the upper and lower pressure rollers convey the steel structures against each other, and can squeeze and straighten the end of the steel structure that needs to be docked. The spraying machine can spray out the anti-rust liquid inside its internal storage tank to protect the steel structure from rust.

[0016] 2. In the above process, the first and second docking plates can be folded when not in use by means of winding rollers, multiple gears and limiting rods, saving space and making it easy to move. When the first and second docking plates change from a vertically folded state to a horizontally extended state, the first and second docking plates can support the steel structure.

[0017] 3. When the steel structure falls under the action of gravity, it is squeezed against the buffer airbag, which compresses the gas inside the buffer airbag into multiple telescopic sleeves and pushes the round rod to slide a distance. Then the round rod will drive the corresponding push plate to slide on the top wall of the second docking plate. The push plate provides thrust from both sides of the steel structure. During the clamping process of the steel structure, it can also center and position the steel structure.

[0018] 4. By setting up multiple lead screws, slide rods and slide blocks, on the one hand, the slide block can drive the docking mechanism to move along the X-axis to adjust and dock the steel structure. On the other hand, the slide block can also drive the docking mechanism to move along the Y-axis to adjust the position of the steel structure for high-altitude docking. Furthermore, by changing the fixed position of the rotating shaft, the slide block can slide along a certain direction between the X-axis and the Y-axis, thereby driving the corresponding steel structure to dock.

The adjustment mechanism includes a slide 9, which slides against the top of the base 1 and can slide arbitrarily in the horizontal direction. The slide 9 is equipped with a docking mechanism. The docking mechanism includes a bracket 16 fixed to the top of the slide 9. The bracket 16 has an inverted U-shape.

The one-way air outlet pipe is fixedly connected to multiple telescopic sleeves 33. The telescopic sleeves 33 are equipped with electronic valves, and the stroke distance of the round rod is determined. After the electronic valve is opened, the gas inside the telescopic sleeves 33 can be discharged. The telescopic sleeves 33 are equipped with balance valves to discharge excess gas after reaching a certain critical air pressure value. Multiple return springs are installed inside the buffer airbag 34. The one-way air inlet pipe only allows external gas to enter the buffer airbag 34, while the one-way air outlet pipe only allows the gas inside the buffer airbag 34 to be squeezed into the telescopic sleeves 33. The buffer airbag 34 is made of elastic material and can expand and contract. The multiple return springs can maintain the inflated state of the buffer airbag 34.

[0029] The adjustment mechanism includes two sets of support members 2 symmetrically arranged on the top wall of the base 1. Each set of support members 2 includes two support blocks 201. The inner walls of the two support blocks 201 are rotatably connected to a first lead screw 3. The side wall of the first lead screw 3 is threadedly connected to a first nut 4. The side wall of the first nut 4 is fixedly connected to a first slide rod 5. The inner walls of the two sets of support blocks 201 are rotatably connected to a second lead screw 6. The side wall of the second lead screw 6 is threadedly connected to a second nut 7. The side wall of the second nut 7 is fixedly connected to a second slide rod 8. The slide seat 9 is slidably connected to the side wall of the first slide rod 5 and the side wall of the second slide rod 8. The first slide rod 5 and the second slide rod 8 are staggered. A drive component is installed on the base 1.

[0030] The drive component includes a drive motor 11 fixedly connected to the base 1 via a column. The output end of the drive motor 11 is fixedly connected to a first one-way bearing 12. The outer ring of the first one-way bearing 12 is fixedly connected to a drive gear 14. A driven gear 15 is fixedly connected to the side wall of one of the first lead screws 3. The drive gear 14 and the driven gear 15 are meshed together. The two first lead screws 3 are connected by a timing belt component 10. The two second lead screws 6 are also connected by a timing belt component 10. The timing belt component 10 includes a drive pulley fixedly connected to the side wall of one of the first lead screws 3 and a driven pulley fixedly connected to the side wall of the other first lead screw 3. The driven pulley and the corresponding drive pulley are connected by a timing belt.

[0031] The inner ring of the first one-way bearing 12 is fixedly connected to the second one-way bearing 13. The side wall of the second one-way bearing 13 is fixedly connected to the shaft 38. The side wall of the shaft 38 is fixedly connected to the first conical wheel 39. One end of the second lead screw 6 is fixedly connected to the second conical wheel 40. The first conical wheel 39 and the second conical wheel 40 are meshed together.

[0032] Each first nut 4 has a first annular airbag 341 fixedly connected to its side wall. The annular airbag is made of elastic material and can expand and contract. The other end of the first annular airbag 341 is fixedly connected to the slide 9. Each second nut 7 has a second annular airbag 342 fixedly connected to its side wall. The other end of the second annular airbag 342 is fixedly connected to the slide 9.

[0033] A spraying frame 35 is fixedly connected to the side wall of the bracket 16. Multiple spraying machines 36 are fixedly connected to the bottom wall of the spraying frame 35. A liquid storage tank 37 is fixedly connected to the side wall of the base 1. A first one-way liquid inlet pipe and a first one-way liquid outlet pipe are fixedly connected through the inner wall of the first annular airbag 341. A second one-way liquid inlet pipe and a second one-way liquid outlet pipe are fixedly connected through the inner wall of the second annular airbag 342. Both the first one-way liquid inlet pipe and the second one-way liquid inlet pipe are fixedly connected to the liquid storage tank 37. Both the first one-way liquid outlet pipe and the second one-way liquid outlet pipe are fixedly connected to the spraying machine 36. The first one-way liquid inlet pipe and the second one-way liquid inlet pipe only allow the rust-preventive liquid inside the liquid storage tank 37 to enter the annular airbag, while the first one-way liquid outlet pipe and the second one-way liquid outlet pipe only allow the rust-preventive liquid inside the annular airbag to be squeezed into the storage tank of the spraying machine 36.

[0034] In this invention, when a high-altitude docking of a steel structure is required, the steel structure is first placed on the upper part of the conveyor frame 17. The upper and lower motors are then turned on, causing the upper pressure roller 21 and the lower pressure roller 22 to rotate in opposite directions and convey the steel structure against each other. This process also straightens the end of the steel structure that needs to be docked. At this time, the sprayer 36 can be turned on, and the rust-preventive liquid inside its internal storage tank can be sprayed out to protect the steel structure from rust. After one end of the steel structure has been conveyed for a certain distance, it will move to the upper part of the second docking plate 27. At this time, the electric slider assembly 19 is adjusted, and the movable end of the electric push rod 18 drives the U-shaped plate 20 to move upward a certain distance. Then, one end of the steel structure will fall to the upper part of the second docking plate 27 under the action of gravity and can slide on the upper part of the second docking plate 27. Several ball bearings are embedded on the top of the second docking plate 27 to facilitate the movement of the steel structure.

[0035] During the rotation of the upper pressure roller 21, it will drive the two winding rollers 31 to rotate, thereby lengthening the rope portion on the winding rollers 31, which in turn drives the first docking plate 23, which is in a vertical state, to rotate. The limiting rod 24 limits the rotation of the first docking plate 23. During the rotation of the first docking plate 23, due to the meshing connection of the first gear 29 and the second gear 30, the Z-shaped plate 26 limits the second docking plate 27, which will also rotate, causing the first docking plate 23 and the second docking plate 27 to change from a vertically folded state to a horizontally extended state. At this time, the upper motor stops rotating, and the lower motor continues to transport the steel structure through the lower pressure roller 22. Subsequently, the first docking plate 23 and the second docking plate 27 can support the steel structure, facilitating subsequent high-altitude docking.

[0036] Once the end of the steel structure furthest from the second docking plate 27 leaves the two pressure rollers, that end will detach from the two pressure rollers and fall under gravity, abutting against the buffer airbag 34. Subsequently, the buffer airbag 34 will be compressed from an inflated state to a deflated state. During this process, the gas inside the buffer airbag 34 will also be squeezed into the multiple telescopic sleeves 33, pushing the round rod to slide a certain distance. The telescopic sleeve 33 consists of a cylinder, a tension spring, and a round rod. The round rod is slidably connected inside the cylinder, and the round rod is elastically connected to the inner wall of the cylinder through the tension spring. In turn, the round rod will drive the corresponding push plate to slide on the top wall of the second docking plate 27. The push plate provides thrust from both sides of the steel structure, and can also center and position the steel structure during the clamping process.

[0037] This completes the straightening, rust prevention, and docking positioning operations of the steel structure. The next step is to move and dock the steel structure. The specific operation is as follows: Turn on the drive motor 11. Drive motor 11 is a reversible motor. When the movable end of drive motor 11 rotates clockwise, it drives the inner ring of the first one-way bearing 12, which is fixedly connected to it, to rotate. The inner ring of the first one-way bearing 12 drives the outer ring of the second one-way bearing 13, which is fixedly connected to it, to rotate. However, at this time, the outer ring of the first one-way bearing 12 can rotate, while the inner ring of the second one-way bearing 13 will not rotate. At this point, the rotating shaft 38 and the second one-way bearing... Since the inner ring of 13 is fixedly connected, the shaft 38 will not rotate. When the outer ring of the first one-way bearing 12 rotates, it will drive the drive gear 14 to rotate. The drive gear 14 drives the meshing driven gear 15 to rotate. The driven gear 15 drives the corresponding first lead screw 3 to rotate. The first lead screw 3 drives another parallel first lead screw 3 to rotate synchronously through the synchronous belt component 10. Then the first nuts 4 connected by the thread on the side walls of the two first lead screws 3 will move synchronously and drive the slide block 9 to move along the X-axis direction through the first slide rod 5. Then the slide block 9 will drive the docking mechanism to move along the X-axis direction to adjust and dock the steel structure.

[0038] In the above process, if the output end of the drive motor 11 rotates counterclockwise, the inner ring of the first one-way bearing 12 will rotate counterclockwise, while the outer ring of the first one-way bearing 12 will not rotate. The inner ring of the first one-way bearing 12 will drive the outer ring of the second one-way bearing 13 to rotate. At this time, the outer ring of the second one-way bearing 13 can drive the inner ring of the second one-way bearing 13 to rotate, and then the rotating shaft 38 will rotate. After the rotating shaft 38 rotates, it will drive the corresponding second lead screw 6 to rotate through the first conical wheel 39 and the second conical wheel 40. The two second lead screws 6 are connected by the synchronous belt component 10, so the two second lead screws 6 will rotate synchronously. Then the second nuts 7 connected by the thread on the side walls of the two second lead screws 6 will move synchronously, and drive the slide block 9 to move along the Y-axis direction through the second slide rod 8. Then the slide block 9 will drive the docking mechanism to move along the Y-axis direction, adjusting the position of the high-altitude docking of the steel structure.

[0039] When it is necessary to connect the steel structure along a certain direction between the X and Y axes, the outer ring of the rotating shaft 38 and the second one-way bearing 13 is fixedly connected.

[0040] If the movable end of the drive motor 11 rotates clockwise, on the one hand, the outer ring of the first one-way bearing 12 will drive the drive gear 14 to rotate, thereby driving the slide 9 to move the docking mechanism along the X-axis. On the other hand, the inner ring of the first one-way bearing 12 will drive the outer ring of the second one-way bearing 13 to rotate, and the outer ring of the second one-way bearing 13 will drive the rotating shaft 38 to rotate. The rotating shaft 38 will then drive the slide 9 to move along the Y-axis through the first conical wheel 39 and the second conical wheel 40, etc. The slide 9 will then drive the docking mechanism to move along the Y-axis. By setting the transmission ratio of the drive gear 14 and the driven gear 15, the slide 9 can slide along a certain direction between the X-axis and the Y-axis, thereby driving the corresponding steel structure to dock.

[0041] During the above process, when the slide 9 slides along the X-axis, it will stretch a second annular airbag 342, drawing the rust-preventive liquid inside the reservoir 37 into the second annular airbag 342, and squeeze another second annular airbag 342, squeezing the rust-preventive liquid inside it into the storage tank of the sprayer 36 for replenishment. When the slide 9 slides along the Y-axis, it will stretch a first annular airbag 341, drawing the rust-preventive liquid inside the reservoir 37 into the first annular airbag 341, and squeezing another first annular airbag 341, squeezing the rust-preventive liquid inside it into the storage tank of the sprayer 36 for replenishment.

[0042] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
