Description

Technical Field

[0001] The present invention belongs to the technical field of steel structure construction, and relates to an automatic docking device, in particular to an automatic steel structure docking device for steel structure construction. Background Art

[0002] A steel structure is a structure composed of steel materials and is 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 sections and steel plates.

[0003] The alignment of steel components is crucial in steel structure projects, and its core value is reflected in the following aspects: ensuring structural safety and stability, optimizing load transfer alignment to ensure that vertical loads are transmitted along the designed path, avoiding additional bending moments caused by eccentric loading, and preventing local stress concentration or instability of components; precise alignment of columns and beams can give full play to the bearing capacity, reduce uneven stress phenomena, and alignment installation can effectively reduce the residual stress after welding or connection, avoiding distortion caused by misalignment; ensuring that the overall structural geometric accuracy meets the specifications, aligning components (such as aligning the center line of the bottom of the steel column with the foundation axis) can quickly locate, reduce adjustment time, and facilitate subsequent operations such as welding and bolt connection; after the columns and beams are aligned, efficient welding can be directly carried out, reducing the construction complexity; ensuring connection reliability, alignment is a prerequisite for high-quality welds, and misalignment will weaken the connection strength and increase the risk of fatigue cracking.

[0004] After retrieval, as disclosed in the Chinese patent document, there is an inclined steel docking structure [Application No.: 201810266911.7; Publication No.: CN 108412850 B]. An inclined steel docking structure includes a cross-steel component, a docking component, a docking steel, an inclination adjustment component and a rectangular sleeve. The docking steel in the device is easy to disassemble, and the angle of the docking steel can be adjusted. The docking steel can also be slid left and right to adjust the position, so that the device can adapt to different usage requirements of steel structures in buildings. The cross-steel component includes a cross-steel bottom plate, cross-steel side plates, a hinge shaft, side chutes, a placement groove, strip grooves and a strip groove plate. Both the front and rear ends of the cross-steel bottom plate are fixedly connected with cross-steel side plates. An arrangement groove is provided at the right end of the cross-steel bottom plate. The left end of the strip groove plate is hinged at the left end position of the arrangement groove through the hinge shaft. A plurality of strip grooves are evenly distributed on the upper end surface of the strip groove plate. Side chutes are provided at the right ends of the cross-steel side plates.

[0005] Although the angle of the docking steel in this patent can be adjusted and the docking steel can also be slid left and right to adjust the position, so that the device can adapt to different usage requirements of steel structures in buildings, however, this device cannot always maintain the alignment and positioning ability of the steel components during docking and subsequent installation and welding, making it impossible to directly carry out efficient welding and increasing the construction complexity. Summary of the Invention

[0006] The purpose of the present invention is to address the above-mentioned problems existing in the existing technology and to propose an automatic docking device for steel structures for steel structure construction. The technical problem to be solved by the invention is: how to always maintain the alignment and positioning capabilities of steel components during the docking and subsequent installation and welding processes, to achieve direct and efficient welding, and to reduce construction complexity.

[0007] The purpose of the present invention can be achieved by the following technical solutions: The invention relates to an automatic docking device for steel structure construction, comprising a docking frame, a docking channel provided in the docking frame, a feed expansion port provided on the docking frame, the feed expansion port being connected to one end of the docking channel, and a conveying assembly for conveying steel structure components is arranged in the docking channel, a stabilizing assembly for limiting the position of the steel structure components is arranged in the docking channel, a regulating roller is rotatably connected in the docking channel, a filling cavity is provided in the docking frame, a filling plate is slidably connected in the filling cavity, a driving assembly for controlling the filling plate to move up and down is arranged in the docking frame, a docking buckle plate is filled in the filling cavity, the docking buckle plate is in an overall ‌冂-shaped structure, and the horizontal plate portion of the docking buckle plate contacts the bottom surface of the filling plate, the docking buckle plate is fixedly matched with the docking position of the two steel structure components, the opposite surfaces of the two vertical plate portions of the docking buckle plate are rotatably connected with a plurality of regulating wheels, the wheel surface of each regulating wheel contacts the outer wall of the steel structure component, and the two vertical plate portions of the docking buckle plate are rotatably connected with The gears are connected in a coaxial manner to the gears of the control gears, and the tooth blocks of the gears are connected to the corresponding control gears at one end and the other end of the gears are connected to the gears of the control gears at the other end.

[0008] The working principle of the present invention is that the two steel structure components can be transported to the docking point in sequence through the conveying component, and the angle and position of the steel structure components can be adjusted by the stabilizing component during the conveying process, so that the two steel structure components can be aligned with each other. When the docking point of the two steel structure components is directly below the filling cavity, the loading plate can be controlled by the driving component to install the docking buckle plate at the docking point of the two steel structure components. When the installation buckle plate is pressed down, each regulating wheel contacts the outer wall of the steel structure component, so that each regulating wheel can rotate. When the regulating wheel rotates, the tooth blocks of the control gear 1 are pushed and matched with the corresponding limit block top surface, so that the regulating wheel can rotate normally when the installation buckle plate is pressed down, and the clamping fit between one end of the limit block and the tooth groove of the control gear 1 makes it possible for the regulating wheel to rotate normally when the docking buckle plate is lifted under normal circumstances due to the clamping state of the limit block and the control gear 1, further making the docking buckle When the plate is normally installed on the steel structure component, it will not be separated from the connection state with the steel structure component. Then, the regulating wheel will drive the meshing bevel gear four to rotate when it is rotating. After the meshing bevel gear four rotates, it will drive the meshing bevel gear three to rotate. After the meshing bevel gear three rotates, it will drive the control screw to rotate. The control screw drives the top pressure fixing block to move, so that the top pressure fixing block can form a top pressure limit on the surface of the steel structure component, further improving the installation stability of the docking gusset plate. After the docking gusset plate is installed at the docking point of the two steel structure components, a simple mutual docking and fixing effect can be formed. Through this ability to pre-dock and fix steel structure components such as square steel columns, it is convenient for subsequent personnel to carry out local welding and structure construction. Docking the structure in advance can reduce the time of on-site construction. Because most steel components are prefabricated in the factory, only assembly and connection are required on site, which significantly improves the construction efficiency and enables the project to enter the use stage faster.

[0009] The conveying assembly includes a plurality of conveying rollers rotatably connected in a docking channel, a transmission bevel gear 1 coaxially fixedly connected to each conveying roller, a plurality of transmission bevel gears 2 rotatably connected in the docking frame, each transmission bevel gear 2 is meshed with the corresponding transmission bevel gear 1, and a driving shaft is rotatably connected in the docking frame, the driving shaft is connected in series with each transmission bevel gear 2, a servo motor 1 is fixed in the docking frame, and the output shaft of the servo motor 1 is coaxially fixedly connected to the driving shaft.

[0010] By adopting the above structure, the driving shaft can be driven to rotate by the servo motor 1, and the driving shaft can drive multiple transmission bevel gears 2 to rotate synchronously. After the multiple transmission bevel gears 2 rotate, they will drive the corresponding transmission bevel gear 1 to rotate. After each transmission bevel gear 1 rotates, it will drive the corresponding conveying roller to operate, thereby realizing the conveying of steel structure components and improving overall work efficiency.

[0011] The stable components include a pair of alignment frames slidably connected in the docking frame and a bidirectional lead screw rotatably connected in the docking frame. A servo motor three is fixed in the docking frame, and the output shaft of the servo motor three is coaxially and fixedly connected with a transmission gear one. A transmission gear two is coaxially fixed on the bidirectional lead screw, and the transmission gear one meshes with the transmission gear two. Both threaded sections on both sides of the bidirectional lead screw are threadedly connected with push arms, and one end of each push arm is fixedly connected to the corresponding alignment frame.

[0012] With the above structure, the servo motor three can drive the transmission gear one to rotate. After the transmission gear one rotates, it will drive the transmission gear two to rotate. After the transmission gear two rotates, it will drive the bidirectional lead screw to rotate. After the bidirectional lead screw rotates, it will drive the two push arms to drive the corresponding alignment frames to move towards each other. When the two alignment frames move towards each other, they will clamp the two steel structure components, making the positions of the two steel structure components align with each other.

[0013] The top inner wall of the docking channel is provided with a pushing cavity. A pressing block is slidably connected in the pushing cavity. A plurality of pushing springs one are fixed between the pressing block and the wall of the pushing cavity, and the bottom surface of the pressing block contacts the top surface of the steel structure component.

[0014] With the above structure, the pushing spring one can make the pressing block always push the steel structure component, thereby preventing the steel structure component from shifting in position during transportation and improving the docking effect.

[0015] The driving components include a pair of reciprocating lead screws rotatably connected in the docking frame and a pair of meshing bevel gears one coaxially fixed at both ends of the regulating roller. Both ends of the loading plate are threadedly connected to the corresponding reciprocating lead screws. A pair of meshing bevel gears two are rotatably connected in the docking frame, and both meshing bevel gears one mesh with the corresponding meshing bevel gears two, and each meshing bevel gear two is coaxially fixed to the reciprocating lead screw.

[0016] With the above structure, when transporting the steel structure component, the steel structure component contacts the regulating roller, further driving the regulating roller to rotate. After the regulating roller rotates, it will drive the corresponding meshing bevel gear one to rotate. After the meshing bevel gear one rotates, it will drive the corresponding meshing bevel gear two to rotate. After the meshing bevel gear two rotates, it will drive the reciprocating lead screw to rotate. After the reciprocating lead screw moves, it will drive the loading plate to move up and down reciprocally. When the docking part of the two steel structure components is transported to be almost directly below the loading cavity, the docking buckle plate can be placed into the loading cavity. At this time, the loading plate presses down the docking buckle plate, making the docking buckle plate fixedly connected to the docking part of the two steel structure components, achieving the effect of pre-fixing.

[0017] A control panel is rotatably connected to the docking buckle plate. At both ends of the control panel, a first winding wheel is coaxially and fixedly connected. A pair of first pulling ropes are fixedly connected to each first winding wheel. The other end of each first pulling rope is fixedly connected to the bottom surface of the corresponding limiting block.

[0018] With the above structure, the control panel can be flipped by personnel, so that the control panel drives the two first winding wheels to rotate, the first winding wheels wind the first pulling ropes, and the first pulling ropes further pull one end of the limiting block to move downward, so as to disengage from the clamping fit with the tooth grooves of the corresponding first control gears, thus facilitating the personnel to disassemble the docking buckle plate from the steel structure component. Moreover, the disassembled docking buckle plate can be reused, improving the service life.

[0019] A plurality of control wheels are rotatably connected to each alignment frame. A plurality of second servo motors are fixed in both alignment frames. The output shaft of each second servo motor is coaxially and fixedly connected to the corresponding control wheel. The wheel surface of each control wheel contacts the surface of the steel structure component. A support arm is fixed on the docking frame. A regulating arm is rotatably arranged on the support arm. A mounting seat is slidably connected to the regulating arm. A chuck is rotatably connected to the mounting seat. A seventh servo motor is fixed in the regulating arm. The rotating shaft of the seventh servo motor is fixedly connected to one end of the support arm. An eighth servo motor is fixed in the regulating arm. A regulating lead screw is rotatably connected in the regulating arm. The output shaft of the eighth servo motor is coaxially and fixedly connected to the regulating lead screw. The regulating lead screw is threadedly connected to the mounting seat. An electric push rod is fixed in the mounting flaring. The output shaft of the electric push rod is fixed with a regulating frame. A welding head is rotatably connected in the regulating frame. A ninth servo motor is fixed in the regulating frame. The output shaft of the ninth servo motor is fixedly connected to the welding head.

[0020] With the above structure, the second servo motors can drive the control wheels to rotate. After the control wheels rotate, they will drive the steel structure component to perform the conveying action. Moreover, the plurality of second servo motors can operate independently, so that the conveying work can be realized more precisely and stably. The docked steel structure component can be clamped by the chuck, and the position of the steel structure component can be adjusted, so that the area not covered by the docking buckle plate is exposed on the top surface. At this time, the electric push rod and the ninth servo motor enable the welding head to reach the docking gap of the steel structure component and weld the gap. After the area not covered by the docking buckle plate is welded, the position of the steel structure component is adjusted again, so that the docking plate is at the top. At this time, the personnel can disassemble the docking buckle plate and then weld the remaining area of the steel structure component docking.

[0021] A discharge tray is fixed on the docking frame. A pair of discharge racks are slidably connected to the discharge tray. A discharge assembly is arranged on each discharge rack. A driving gear one is rotatably connected in the discharge tray. The rotating shafts on both sides of the driving gear one are coaxially and fixedly connected with driving lead screws. The threads of the two driving lead screws face in opposite directions. Both driving lead screws are threadedly connected to the corresponding discharge racks. A servo motor four is fixed in the discharge tray. The output shaft of the servo motor four is coaxially and fixedly connected with a driving gear two. The driving gear two meshes with the driving gear one.

[0022] With the above structure, after the steel structure components are butted and then conveyed out of the docking channel, at this time, the servo motor four drives the driving gear two to rotate. After the driving gear two rotates, it will drive the driving gear one to rotate. After the driving gear one rotates, it will drive the two driving lead screws to operate, so as to realize the relative or opposite movement of the two discharge racks, and complete the connection and disconnection with the steel structure components.

[0023] A plurality of discharge wheels are rotatably connected to the opposite surfaces of the two discharge racks. The wheel surfaces of each discharge wheel are in contact with the surface of the steel structure component. A plurality of servo motors five are fixed in each of the two discharge racks. The output shaft of each servo motor five is coaxially and fixedly connected with the corresponding discharge wheel.

[0024] With the above structure, a plurality of servo motors five can drive the corresponding discharge wheels to rotate, so as to normally complete the discharge work of the steel structure components, and thus take out the butted steel structure components, improving the overall working effect.

[0025] Receiving grooves are formed in both of the two discharge racks. A stabilizing arm is slidably connected in each receiving groove. The protruding part of each stabilizing arm is in contact with the top surface of the steel structure component. A second pushing spring is fixed between each stabilizing arm and the corresponding receiving groove. A servo motor six is fixed in each of the two discharge racks. A winding wheel two is coaxially and fixedly connected to the driving shaft of each servo motor six. A second pull rope is fixed between each winding wheel two and the corresponding stabilizing arm.

[0026] With the above structure, the servo motor six can drive the winding wheel two to rotate. After the winding wheel two rotates, it will pull the stabilizing arm to press down, so that the stabilizing arm can limit the steel structure component, preventing the position of the steel structure component from shifting during the discharging process, and improving the stability of the overall operation.

[0027] Compared with the prior art, the steel structure automatic docking device for steel structure construction has the following advantages: 1. After installing the docking buckle plates at the docking joints of two steel structure components, a simple effect of mutual docking and fixation can be formed. Through this pre-docking and fixation ability, it is convenient for subsequent personnel to carry out local welding and structure erection. Docking the structure in advance can reduce the on-site construction time. Since most steel components are prefabricated in the factory and only assembly and connection are required on-site, this significantly improves the construction efficiency and enables the project to enter the use stage faster.

[0028] 2. By flipping the control board by personnel, the control board drives two reel wheels I to rotate, causing the reel wheel I to reel in the pulling rope I. The pulling rope I further pulls one end of the limit block to move downward, causing it to disengage from the clamping fit with the tooth groove of the corresponding control gear I, so that it is convenient for personnel to disassemble the docking buckle plate from the steel structure component. And the disassembled docking buckle plate can be reused, improving the service life. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0043] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.

[0044] Such as Figures 1 - 13As shown, an automatic docking device for steel structure construction includes a docking frame 1, a docking channel 2 provided in the docking frame 1, a feed expansion opening 3 provided on the docking frame 1, the feed expansion opening 3 is connected to one end of the docking channel 2, and a conveying assembly for conveying steel structure components is provided in the docking channel 2, a stabilizing assembly for limiting the position of the steel structure components is provided in the docking channel 2, a regulating roller 51 is rotatably connected in the docking channel 2, a loading cavity 4 is provided in the docking frame 1, a loading plate 5 is slidably connected in the loading cavity 4, and the docking A driving assembly for controlling the loading plate 5 to move up and down is arranged in the frame 1, and a docking plate 6 is filled in the loading cavity 4. The docking plate 6 is in an overall ‌冂-shaped structure, and the horizontal plate portion of the docking plate 6 contacts the bottom surface of the loading plate 5. The docking plate 6 is fixedly matched with the docking portion of the two steel structure components. The opposite surfaces of the two vertical plate portions of the docking plate 6 are rotatably connected with a plurality of regulating wheels 7, and the wheel surface of each regulating wheel 7 contacts the outer wall of the steel structure component, and the two vertical plate portions of the docking plate 6 are rotatably connected with a plurality of limit blocks. 8 and multiple control gears 9, each limit block 8 and each control gear 9 are fixed with a torsion spring at the rotating shaft, each control gear 9 is coaxially fixedly connected with the corresponding regulating wheel 7, each limit block 8 is in an arc-shaped strip shape as a whole, and the tooth block of each control gear 9 is pushed and matched with the top surface of the corresponding limit block 8, and one end of each limit block 8 is snap-fitted with the tooth groove of the corresponding control gear 9, and multiple top pressure fixing blocks 10 are slidably connected in the two vertical plate parts of the docking buckle plate 6, and each top pressure fixing block 1 0 is fixed with an anti-skid pad 11 at one end, each anti-skid pad 11 is pressed against the surface of the steel structure component, and multiple meshing bevel gears three 12 are rotatably connected in the two vertical plate parts of the docking buckle plate 6, and each control gear one 9 is coaxially fixedly connected with a meshing bevel gear four 13, each meshing bevel gear four 13 is meshed with the meshing bevel gear three 12, and each meshing bevel gear three 12 is coaxially fixedly connected with a control screw 14, and each control screw 14 is threadedly connected to the corresponding top pressure fixing block 10.

[0045] The two steel structure components can be transported to the docking point in sequence by the conveying component, and the angle and position of the steel structure components can be adjusted by the stabilizing component during the conveying process, so that the two steel structure components can be aligned with each other. When the docking point of the two steel structure components is directly below the filling cavity 4, the loading plate 5 can be controlled by the driving component to install the docking buckle plate 6 at the docking point of the two steel structure components. When the installation buckle plate is pressed down, each regulating wheel 7 contacts with the outer wall of the steel structure component, so that each regulating wheel 7 can rotate. When the regulating wheel 7 rotates, the tooth blocks of the control gear 9 are pushed and matched with the corresponding limit block 8 top surface, so that the regulating wheel 7 can rotate normally when the installation buckle plate is pressed down. Through the clamping fit between one end of the limit block 8 and the tooth groove of the control gear 9, when the docking buckle plate 6 is lifted under normal circumstances, the regulating wheel 7 cannot rotate due to the clamping state of the limit block 8 and the control gear 9, further making the docking When the gusset plate 6 is normally installed on the steel structure component, it will not be separated from the connection state with the steel structure component. Then, through the regulating wheel 7, it will drive the meshing bevel gear four 13 to rotate in the rotating state. After the meshing bevel gear four 13 rotates, it will drive the meshing bevel gear three 12 to rotate. After the meshing bevel gear three 12 rotates, it will drive the control screw 14 to rotate. The control screw 14 drives the top pressure fixing block 10 to move, so that the top pressure fixing block 10 has the ability to form a top pressure limit on the surface of the steel structure component, further improving the installation stability of the docking gusset plate 6. After the docking gusset plate 6 is installed at the docking point of the two steel structure components, a simple mutual docking and fixing effect can be formed. Through this pre-docking and fixing ability, it is convenient for subsequent personnel to carry out local welding and structure construction. Docking the structure in advance can reduce the time of on-site construction. Because most steel components are prefabricated in the factory, only assembly and connection are required on site, which significantly improves the construction efficiency and enables the project to enter the use stage faster.

[0047] With the above structure, the servo motor 1 can drive the drive shaft 18 to rotate. The drive shaft 18 drives a plurality of transmission bevel gears 17 to rotate synchronously. After the plurality of transmission bevel gears 17 rotate, they will drive the corresponding transmission bevel gears 16 to rotate. After each transmission bevel gear 16 rotates, it will drive the corresponding conveying roller 15 to operate, so as to realize the conveying of steel structure components and improve the overall working efficiency.

[0048] The stabilizing assembly includes a pair of alignment frames 20 slidably connected in the docking frame 1, a bidirectional lead screw 21 rotatably connected in the docking frame 1, a servo motor 3 fixed in the docking frame 1, a transmission gear 23 coaxially fixed to the output shaft of the servo motor 3, a transmission gear 24 coaxially fixed to the bidirectional lead screw 21, the transmission gear 23 meshes with the transmission gear 24, and both threaded sections of the bidirectional lead screw 21 are threadedly connected with a push arm 25, and one end of each push arm 25 is fixedly connected to the corresponding alignment frame 20.

[0049] With the above structure, the servo motor 3 can drive the transmission gear 23 to rotate. After the transmission gear 23 rotates, it will drive the transmission gear 24 to rotate. After the transmission gear 24 rotates, it will drive the bidirectional lead screw 21 to rotate. After the bidirectional lead screw 21 rotates, it will drive the two push arms 25 to drive the corresponding alignment frames 20 to move relatively. When the two alignment frames 20 move relatively, they will clamp two steel structure components, so that the positions of the two steel structure components can be aligned.

[0050] A pushing cavity 26 is formed in the top inner wall of the docking channel 2. A pressing block 27 is slidably connected in the pushing cavity 26.

[0053] With the above structure, when transporting steel structure components, the steel structure components come into contact with the regulating roller 51, further driving the regulating roller 51 to rotate. After the regulating roller 51 rotates, it will drive the corresponding meshing bevel gear one 30 to rotate. After the meshing bevel gear one 30 rotates, it will drive the corresponding meshing bevel gear two 31 to rotate. After the meshing bevel gear two 31 rotates, it will drive the reciprocating lead screw 29 to rotate. After the reciprocating lead screw 29 moves, it will drive the loading plate 5 to move up and down reciprocally. When the butt joint of two steel structure components is transported to be almost directly below the loading cavity 4, the butt joint buckle plate 6 can be placed into the loading cavity 4. At this time, the loading plate 5 presses down the butt joint buckle plate 6, enabling the butt joint buckle plate 6 to be fixedly connected to the butt joint of the two steel structure components, achieving the effect of pre-fixation.

[0054] A control plate 32 is rotatably connected to the butt joint buckle plate 6. At both ends of the control plate 32, a first winding wheel 33 is coaxially and fixedly connected. A pair of first pull ropes 34 are fixedly connected to each first winding wheel 33. The other end of each first pull rope 34 is fixedly connected to the bottom surface of the corresponding limiting block 8.

[0055] With the above structure, by a person flipping the control plate 32, the control plate 32 drives the two first winding wheels 33 to rotate, causing the first winding wheels 33 to wind the first pull ropes 34. The first pull ropes 34 further pull one end of the limiting block 8 to move downward, disengaging from the clamping fit with the tooth grooves of the corresponding control gear one 9, thus facilitating the person to disassemble the butt joint buckle plate 6 from the steel structure component. Moreover, the disassembled butt joint buckle plate 6 can be reused, improving its service life.

[0058] With the above structure, after the steel structure components are butted and then conveyed out of the butting channel 2, at this time, the fourth servo motor 41 drives the second driving gear 42 to rotate. After the second driving gear 42 rotates, it will drive the first driving gear 39 to rotate. After the first driving gear 39 rotates, it will drive the two driving lead screws 40 to operate, so as to realize the relative or opposite movement of the two discharging racks 38, and complete the connection and disconnection with the steel structure components.

A plurality of fifth servo motors 44 are fixed in each of the two discharging racks 38.

[0060] With the above structure, the corresponding discharging wheels 43 can be driven to rotate by a plurality of fifth servo motors 44, so as to normally complete the discharging work of the steel structure components, and take out the butted steel structure components, thereby improving the overall working effect.

[0061] Receiving grooves 45 are formed in both of the two discharging racks 38. A stabilizing arm 46 is slidably connected in each receiving groove 45.

[0062] With the above structure, the second winding wheel 49 can be driven to rotate by the sixth servo motor 48. After the second winding wheel 49 rotates, it will pull the stabilizing arm 46 to press down, so that the stabilizing arm 46 can limit the steel structure component, prevent the position of the steel structure component from shifting during the discharging process, and improve the stability of the overall operation.

[0063] The working principle of the present invention is as follows: the driving shaft 18 is driven to rotate by the servo motor 19, and the driving shaft 18 drives multiple transmission bevel gears 2 17 to rotate synchronously. After the multiple transmission bevel gears 2 17 rotate, they will drive the corresponding transmission bevel gear 1 16 to rotate. After each transmission bevel gear 1 16 rotates, it will drive the corresponding conveying roller 15 to operate, so as to realize the conveying of steel structure components. The transmission gear 1 23 is driven to rotate by the servo motor 3 22. After the transmission gear 1 23 rotates, it will drive the transmission gear 2 24 to rotate. After the transmission gear 2 24 rotates, it will drive the bidirectional lead screw 21 to rotate. After the bidirectional lead screw 21 rotates, it will drive the two push arms 25 to drive the corresponding alignment frame 20 to rotate relative to each other. When the two alignment frames 20 move relative to each other, they clamp the two steel structure components so that the positions of the two steel structure components can be relatively aligned. The push spring 1 28 allows the pressure block 27 to always push the steel structure components, thereby preventing the steel structure components from being offset during transportation and improving the docking effect. When the steel structure components are transported, the steel structure components contact the regulating roller 51, which further drives the regulating roller 51 to rotate. After the regulating roller 51 rotates, it drives the corresponding meshing bevel gear 1 30 to rotate. After the meshing bevel gear 1 30 rotates, it drives the corresponding meshing bevel gear 2 31 to rotate. After the meshing bevel gear 2 31 rotates, it drives the reciprocating screw 29 to rotate. The reciprocating screw 29 After the movement, it will drive the filling plate 5 to move up and down reciprocatingly. When the docking point of the two steel structure components is transported to almost directly below the filling cavity 4, the docking buckle plate 6 can be placed in the filling cavity 4. At this time, the docking buckle plate 6 is pressed down by the filling plate 5. When the installation buckle plate is pressed down, each regulating wheel 7 contacts the outer wall of the steel structure component, so that each regulating wheel 7 can rotate. When the regulating wheel 7 rotates, the tooth blocks of the control gear 9 are pushed and matched with the corresponding limit block 8 top surface, so that the regulating wheel 7 can rotate normally when the installation buckle plate is pressed down. Through the clamping fit between one end of the limit block 8 and the tooth groove of the control gear 9, under normal circumstances, when the docking buckle plate 6 is lifted, the regulating wheel 7 will be lifted due to the limit block. 8 is in a stuck-on state with the control gear 9 and cannot rotate, further ensuring that the docking buckle plate 6 will not be separated from the connection state with the steel structure component when normally installed on the steel structure component, and then the regulating wheel 7 will drive the meshing bevel gear four 13 to rotate in the rotating state, and the meshing bevel gear four 13 will drive the meshing bevel gear three 12 to rotate after the rotation, and the meshing bevel gear three 12 will drive the control screw 14 to rotate after the rotation, and the control screw 14 drives the top pressure fixing block 10 to move, so that the top pressure fixing block 10 has the ability to form a top pressure limit on the surface of the steel structure component, further improving the installation stability of the docking buckle plate 6, and after the docking buckle plate 6 is installed at the docking point of the two steel structure components, a simple mutual docking and fixing effect can be formed.

[0064] In summary, the two steel structure components are transported to the docking point in sequence through the conveying assembly, and the angle and position of the steel structure components are adjusted by the stabilizing assembly during the conveying process, so that the two steel structure components can be aligned with each other. When the docking point of the two steel structure components is directly below the filling cavity 4, the loading plate 5 can be controlled by the driving assembly to install the docking buckle plate 6 at the docking point of the two steel structure components. When the installation buckle plate is pressed down, each regulating wheel 7 contacts the outer wall of the steel structure component, so that each regulating wheel 7 can rotate. When the regulating wheel 7 rotates, the tooth blocks of the control gear 9 are pushed and matched with the corresponding limit block 8 top surface, so that the regulating wheel 7 can rotate normally when the installation buckle plate is pressed down. Through the clamping fit between one end of the limit block 8 and the tooth groove of the control gear 9, when the docking buckle plate 6 is lifted under normal circumstances, the regulating wheel 7 cannot rotate due to the clamping state of the limit block 8 and the control gear 9, which further makes the When the buckle plate 6 is normally installed on the steel structure component, it will not be separated from the connection state with the steel structure component. Then, through the regulating wheel 7, it will drive the meshing bevel gear four 13 to rotate in the rotating state. After the meshing bevel gear four 13 rotates, it will drive the meshing bevel gear three 12 to rotate. After the meshing bevel gear three 12 rotates, it will drive the control screw 14 to rotate. The control screw 14 drives the top pressure fixing block 10 to move, so that the top pressure fixing block 10 has the ability to form a top pressure limit on the surface of the steel structure component, further improving the installation stability of the docking buckle plate 6. After the docking buckle plate 6 is installed at the docking point of the two steel structure components, a simple mutual docking and fixing effect can be formed. Through this pre-docking and fixing ability, it is convenient for subsequent personnel to carry out local welding and structure construction. Docking the structure in advance can reduce the time of on-site construction. Because most steel components are prefabricated in the factory, only assembly and connection are required on site, which significantly improves the construction efficiency and enables the project to enter the use stage faster.
