Technical Field

[0001] The invention relates to the technical field of steel structure engineering construction, and in particular to a purlin efficient butt-jointing, punching and installation operating platform and a construction method. Background Art

[0002] Marine new energy engineering is one of the emerging development directions in my country's future engineering construction field. Considering the difficulty of offshore assembly, large modular assembly production of onshore steel platforms for marine engineering and offshore large module splicing are the future development directions of construction methods.

[0003] The large modular assembly production of onshore steel structures involves welding, assembly and punching of steel purlins. In new energy projects, the current traditional positioning welding tooling still has the following main shortcomings:

[0004] (1) The hole spacing and assembly error on the purlin are high;

[0005] (2) There is a lack of a device that can move on the purlins, so manual handling is required, and welding and punching also need to be done manually. Summary of the Invention

[0006] In view of the above-mentioned technical problems existing in the existing purlin installation, the purpose of the present invention is to provide a purlin efficient docking and punching installation operation platform and construction method, which can be movably installed at a group of purlin connections. The robot installed on it can implement high-altitude, welding, and punching construction of purlins without manual operation, and can be quickly installed, operated, and disassembled by two people. In addition, a second pallet and a third pallet are set on the platform for punching positioning. After moving to the connection or punching position through the walking mechanism, the limiter is placed to position the second pallet with the installed purlin hole position, and then the third pallet is aligned with the purlin to be installed and holes are drilled, so that the hole positions on the purlin always maintain the same spacing as the second pallet and the third pallet.

[0007] In order to achieve the above-mentioned purpose, the present invention provides a purlin efficient docking and drilling installation operation platform, which includes a positioning tool chassis, a detachable support truss, two rotatable equipment carrying platforms, a traveling mechanism, a control box and electrical equipment;

[0008] The positioning tool chassis is movably arranged on two purlins through a walking mechanism, and the positioning tool chassis includes a first mounting platform and a second mounting platform connected to each other.

[0009] The two rotatable equipment carrying platforms are arranged on the second mounting platform, and can be used to accommodate the welding robot and the drilling robot respectively;

The first guide hook and the second guide hook have the same structure and are both C-shaped. One end of the first guide hook and the second guide hook fits in the slot with a mortise and tenon joint and can clamp the purlin.

[0015] The two first guide hooks clamp the two installed purlins to limit the displacement of the positioning tool chassis perpendicular to its moving direction. The positioning tool chassis is further moved to align the positioning holes on the second supporting plates at both ends of the second keel with the hole positions of the installed purlins. The position of the positioning tool chassis is positioned by sequentially passing the limiting members through the positioning holes of the second supporting plates and the holes of the installed purlins.

[0016] The two second guide hooks are used to hang and support the purlins to be installed. The purlins to be installed are passed through the two second guide hooks and docked with the installed purlins. By rotating the rotatable equipment carrying platform, the welding robot is rotated to the purlin connection to perform purlin welding operations. After welding is completed, the rotatable equipment carrying platform is rotated to rotate the drilling robot to the purlin connection, pass through the positioning holes on the third support plate at both ends of the third keel, and perform drilling operations on the purlins to ensure that the hole positions on the installed purlins and the purlins to be installed always maintain the same spacing between the positioning holes on the second support plate and the positioning holes on the third support plate during butt welding.

[0022] Furthermore, the main truss includes short cross bars, long cross bars, vertical bars, and diagonal bars;

[0023] The short crossbar is shorter than the long crossbar, and the two are arranged in pairs. The vertical rod is vertically connected to the opposite end of the short crossbar and the long crossbar, and the diagonal rod is obliquely connected to the other end of the short crossbar and the long crossbar. A number of support rods are connected between the short crossbar and the long crossbar and between the diagonal rod and the long crossbar; a number of threaded nuts are provided at the bottom of the long crossbar for connecting to the first mounting platform and the second mounting platform;

[0024] Two second quick-insert locking pins are provided on the top of the short crossbar for connection with the secondary truss;

[0025] The secondary truss includes two triangular frames and a second threaded nut. The two triangular frames are in the shape of a right triangle.

[0029] Furthermore, the turntable rotating motor is arranged on the second mounting platform, which consists of a DC motor and a driving wheel driven by the DC motor. The driving wheel is in contact with the equipment mounting turntable, and the driving wheel is driven to rotate by the DC motor, and the driving wheel drives the equipment mounting turntable to rotate.

[0030] Furthermore, the walking mechanism is composed of a number of driven wheels, a number of driving wheels, a number of driving motors and a vibration-damping suspension;

DETAILED DESCRIPTION

[0054] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0055] The installation operation platform provided by the present invention can be movably set on the two purlins 900 that have been installed, and is used to connect the purlin 900 to be installed with the purlin 900 that has been installed. The installation operation platform can splice the two purlins 900, and after splicing, welding and positioning and punching are performed through the equipment on it, so that the splicing and hole positions between the purlins 900 are always consistent.

[0056] See also Figure 1 , which is a structural schematic diagram of the purlin efficient docking, punching and installation operation platform provided by the present invention.

[0057] As can be seen from the diagram, the purlin efficient docking, punching and installation operation platform provided by the present invention includes five components: a positioning tool chassis 100, a detachable support truss 200, two rotatable equipment carrying platforms 300, a walking mechanism 400, and a control box and electrical equipment 500.

[0058] The positioning tool chassis 100 is movably arranged on two purlins 900 through a walking mechanism 500. The positioning tool chassis 100 includes a first mounting platform 110 and a second mounting platform 120 connected to each other.

[0059] Two rotatable equipment carrying platforms 300 are provided on the second mounting platform 120 , and can be used to accommodate a welding robot 700 and a drilling robot 800 respectively;

[0060] The control box and electrical equipment 500 are installed on the first installation platform 110 and are used to control the walking mechanism 400, the welding robot 700, and the drilling robot 800 and provide them with power;

[0061] like Figure 2 , Figure 3 The bottom of the first installation platform 110 is provided with a first keel 111 and a second keel 112 perpendicular to the purlin 900;

[0062] A third keel 121 perpendicular to the purlin 900 is provided at the bottom of the second mounting platform 120;

[0063] A first support plate 111a and a second support plate 112a are respectively provided at the bottom of the two ends of the first keel 111 and the second keel 112, corresponding to the two purlins 900. A third support plate 121a is provided at the bottom of the two ends of the third keel 121, corresponding to the two purlins 900. Positioning holes 112b are provided on the second support plate 112a and the third support plate 121a. Slots 113 are provided at the ends of the first keel 111 and the third keel 121.

[0064] A first guide hook 620 and a second guide hook 630 are respectively inserted into the slots 113 at both ends of the first keel 111 and the third keel 121. The first guide hook 620 and the second guide hook 630 have the same structure and are both C-shaped. One end of the first guide hook 620 and the second guide hook 630 fits in the slot 113 with a mortise and tenon joint to clamp the purlin 900.

[0065] The two first guide hooks 620 clamp the two installed purlins 900 to limit the displacement of the positioning tool chassis 100 perpendicular to its moving direction. The positioning tool chassis 100 is further moved until the positioning holes 112b on the second support plates 112a at both ends of the second keel 112 are aligned with the holes of the installed purlins 900. The position of the positioning tool chassis 100 is positioned by sequentially passing the limiting members 610 through the positioning holes 112b of the second support plates 112a and the holes of the installed purlins 900.

[0066] When the purlin 900 to be installed is ready to be docked with the installed purlin 900, the two second guide hooks 630 can be used as hooks to form an integral force-bearing structure with the positioning tool chassis 100 and the detachable support truss 200, which plays the role of auxiliary lifting and temporary fixation of the purlin 900.

[0067] Furthermore, the two second guide hooks 630 are used to hang and support the purlin 900 to be installed. The purlin 900 to be installed is passed through the two second guide hooks 630 and docked with the installed purlin 900. By rotating the rotatable equipment carrying platform 300, the welding robot 700 is rotated to the connection between the purlin 900 to perform the purlin 900 welding operation. After the welding is completed, the rotatable equipment carrying platform 300 is rotated to rotate the drilling robot 800 to the connection between the purlin 900 and pass through the positioning holes 112b on the third support plate 121a at both ends of the third keel 121 to perform the drilling operation on the purlin 900.

[0068] After completion, the positioning tool chassis 100 is moved to align the positioning holes 112b on the second support plates 112a at both ends of the second keel 112 with the holes just drilled on the purlin 900, and the position of the positioning tool chassis 100 is positioned by passing through the positioning holes 112 and the holes on the purlin 900 in sequence through the limiting members 610. Then, the purlin 900 is drilled through the positioning holes 112b on the third support plates 121a at both ends of the third keel 121 by the drilling robot 800, and so on. This ensures that the hole positions on the installed purlin 900 and the purlin to be installed always maintain the same spacing as the positioning holes 112b on the second support plate 112a and the positioning holes 112b on the third support plate 121a during butt welding.

[0069] Compared with the existing technology, the installation operation platform provided by this solution can be movably installed at a group of purlin connections. The robot installed on it can perform purlin high-altitude, welding, and drilling construction without manual operation;

[0070] It can be quickly installed, operated and disassembled by two people, and the second and third support plates are set on the platform for drilling positioning, so that the hole positions on the purlins always keep the same spacing with the second and third support plates.

[0071] Specifically, such as Figure 2 The first mounting platform 110 and the second mounting platform 120 are connected by a main connecting keel 130. The main connecting keel 130 is vertically arranged with the purlin 900 and connected in the middle of the bottom of the first mounting platform 110 and the second mounting platform 120 to connect the two.

[0072] In order to further improve the reliability of the connection, secondary connection keels 140 are equidistantly provided on both sides of the main connection keel 130 , and the secondary connection keels 140 are respectively connected to the bottom of the first installation platform 110 and the second installation platform 120 .

[0073] Furthermore, the first keel 111, the second keel 112, and the third keel 121 have the same structure. All three are rectangular tubes with openings at both ends. The openings at both ends of the rectangular tube are slots 113. A mortise and tenon structure is provided in the slots 113. In conjunction with the mortise and tenon structure, one end of the first guide hook 620 and the second guide hook 630 is provided with a tenon structure corresponding to the mortise and tenon structure.

[0074] like Figure 4 , Figure 5 The detachable support truss 200 includes a main truss 210 and two sub-trusses 220. The bottom of the main truss 210 is provided with a plurality of threaded nuts 201. The tops of the first mounting platform 110, the second mounting platform 120, and the main connecting keel 130 connected between the first mounting platform 110 and the second mounting platform 120 are provided with a plurality of quick-insert locking pins 202 corresponding to the threaded nuts 201.

[0075] The main truss 210 is connected to the first mounting platform 110 and the second mounting platform 120 by connecting a plurality of threaded nuts 201 with a plurality of quick-insert locking pins 202;

[0076] Two sub-trusses 220 are respectively provided with insertion slots 222, and the two sub-trusses 220 are inserted on the main truss 110 through the insertion slots 222. The bottom of the insertion slot 222 is provided with a second threaded nut 203, and the bottom of the sub-truss 220 is provided with a plurality of third threaded nuts 204. The top of the main truss 210 is provided with a second quick insertion locking pin 205 corresponding to the second threaded nut 203, and the first installation platform 110 is provided with a plurality of third quick insertion locking pins 206 corresponding to the third threaded nuts 204. The second threaded nut 203 is connected with the second quick insertion locking pin 205, and the third threaded nut 204 is connected with the third quick insertion locking pin 206, so as to realize the connection of the sub-truss 220 with the main truss 210 and the first installation platform 110.

[0077] The specific structure of the main truss 210 and the two sub-trusses 220 is not limited, and can be determined according to actual needs.

[0078] For example, Figure 4 The main truss 210 includes a short cross bar 211, a long cross bar 212, a vertical bar 213, and an inclined bar 214.

[0079] The length of the short cross bar 211 is less than that of the long cross bar 212, and the two are arranged in two pairs. The vertical bar 213 is connected perpendicularly to one end of the short cross bar 211 opposite to the long cross bar 212, and the inclined bar 214 is connected obliquely to the other end of the short cross bar 211 opposite to the long cross bar 212. A plurality of supporting bars 215 are connected between the short cross bar 211 and the long cross bar 212 and between the inclined bar 214 and the long cross bar 212. The bottom of the long cross bar 212 is provided with a plurality of threaded nuts 201 for connecting with the first installation platform 110 and the second installation platform 120.

[0080] The top of the short cross bar 211 is provided with two second quick insertion locking pins 205 for connecting with the sub-truss 220.

[0081] For example, Figure 5 Further, the sub-truss 220 includes two triangular frames 221, a second threaded nut 203, and a plurality of third threaded nuts 204. The two triangular frames 221 are arranged in a right triangle shape and symmetrically, and a gap is arranged between the two triangular frames 211. The second threaded nut 203 is located in the gap and connected with the top of the two triangular frames 211 respectively. The gap cooperates with the second threaded nut 203 to form an insertion slot 222. The bottom of the two triangular frames 211 is provided with a plurality of third threaded nuts 204. In this way, the sub-truss 220 is inserted on the main truss 210 through the insertion slot 222 between the two triangular frames 221 and connected with the second quick insertion locking pin 205 at the top of the short cross bar 211 through the second threaded nut 203. The bottom of the two triangular frames 221 is connected with a plurality of third quick insertion locking pins 206 on the first installation platform 110.

[0082] For example, Figure 6Furthermore, the rotatable equipment mounting platform 300 includes an equipment mounting turntable 310 and a turntable rotation motor 320.

[0083] The equipment mounting plate 310 is annular in shape and has a plurality of mounting holes on its surface for connecting the drilling robot 800 or the drilling robot 900;

[0084] The inner circle of the equipment installation turntable 310 is provided with a ball bearing, and the outer circle is provided with rubber and contacts the driving wheel in the turntable rotating motor 320; the inner ring of the ball bearing is connected to the turntable fixing shaft 330, and the equipment installation turntable 310 is fixed on the second installation platform 120 through the turntable fixing shaft 330.

[0085] like Figure 7 The above-mentioned turntable rotating motor 320 is arranged on the second installation platform 120, and is composed of a DC motor 321 and a driving wheel 322 driven by the DC motor. The driving wheel 322 is in contact with the equipment installation turntable 310, and the driving wheel 322 is driven to rotate by the DC motor 321, and the driving wheel 322 drives the equipment installation turntable 310 to rotate.

[0086] like Figure 8 The walking mechanism 400 is composed of a plurality of driven wheels 410, a plurality of driving wheels 420, a plurality of driving motors and a vibration-damping suspension 430;

[0087] A number of driven wheels 410 are respectively arranged on the lower surfaces of the first support plate 111a, the second support plate 112a, and the third support plate 121a. The driving motor and the vibration-damping suspension 430 are arranged on 104 and installed on the upper surface of the first mounting platform 110. A number of driving wheels 420 are respectively connected to the driving motor and the vibration-damping suspension 430. The driving motor and the vibration-damping suspension 430 drive the driving wheels 420 to rotate, so that the positioning tooling chassis 100 moves along the surface of the purlin 900, and the first guide hook 620 is used to ensure that it can move in a straight line.

[0088] like Figure 9 The control box and electrical equipment 500 are composed of two welding machine electrical boxes 510, a control cabinet 520, and a battery 530 installed on the first installation platform 110. The battery 530 is electrically connected to the control cabinet 520, the welding machine electrical box 510, and the drive motor and vibration damping suspension 430 respectively. The control cabinet 520 is connected to the drive motor and vibration damping suspension 430 to control the drive motor and vibration damping suspension 430.
