[0060] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0061] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0062] like Figures 1-4 As shown, the present invention provides a telescopic suspended platform for welding tubular trusses, comprising:

[0063] Fixed support 1 is used to connect to truss chord 9;

[0064] Telescopic guide 2 is installed above truss chord 9 and is connected to truss chord 9 through fixed support 1;

[0065] The basket body 3 has a telescopic guide rod 4 at its top. The position of the telescopic guide rod 4 inserted into the telescopic guide frame 2 is adjusted according to the diameter of the truss chord 9, and is limited by the fixing part 5.

[0066] The working principle and beneficial effects of the above technical solution are as follows: The installation position of the telescopic suspended platform is determined based on the on-site high-altitude construction conditions; a fixed support 1 is fabricated according to the diameter of the truss chord 9 and welded to the upper surface of the truss chord 9, ensuring a tight connection; the telescopic guide rod 4 extends and retracts within the telescopic guide frame 2, thereby adjusting the distance between the platform of the basket 3 and the truss chord 9, and adjusting the distance between the operator and the truss steel pipe; the telescopic guide rod 4 is firmly fixed to the telescopic guide frame 2 using fasteners 5; after confirming through construction simulation that the installation position of the telescopic suspended platform will not affect the installation of the truss structure, the telescopic suspended platform is installed on the truss chord 9 before the truss structure is hoisted; the telescopic suspended platform is used for welding the pipe truss connection nodes, and after completion, it is dismantled, with the fixed support 1 removed using safety ropes; during storage and transportation, the telescopic suspended platform can be disassembled for easy handling.

[0067] Through the above design, the telescopic and adjustable function of the suspended platform solves the problem of using a single-size suspended platform for high-altitude welding of pipe trusses with various pipe diameters, saving a significant amount of suspended platform manufacturing. Based on the pipe diameter of the truss chord 9, the platform 3 of the basket extends and retracts within the telescopic guide frame 2 via the telescopic guide rod 4, adjusting the distance between the operator and the truss steel pipe. This telescopic adjustment mechanism allows the suspended platform to be adapted to welding operations with different pipe diameters, further saving on suspended platform manufacturing. Furthermore, after use, the telescopic suspended platform can be disassembled for easy storage and transportation. The entire telescopic suspended platform system is reusable, increasing reusability and saving costs.

[0068] like Figure 5 As shown, in one embodiment, the side of the fixed support 1 that connects to the truss chord 9 is an arc-shaped surface 110 corresponding to the truss chord 9, and the fixed support 1 and the truss chord 9 are connected by fillet weld.

[0069] The working principle and beneficial effects of the above technical solution: The fillet weld refers to the weld welded along the intersection line of two orthogonal or nearly orthogonal parts. The arc-shaped surface 110 of the fixed support 1 is made according to the outer diameter of the truss chord 9, and then the two are welded together.

[0070] like Figure 6 As shown, in one embodiment, the telescopic guide 2 includes:

[0071] Two parallel conduits 210 are used for inserting the telescopic guide rod 4, and the conduits 210 are connected to the basket 3 through the telescopic guide rod 4;

[0072] The first frame rod 220 is used to connect the two conduits 210.

[0073] A third support rod 230 is also connected between the two conduits 210, and the third support rod 230 can be an angle steel.

[0074] The working principle and beneficial effects of the above technical solution are as follows: Both conduits 210 are in contact with the top surface of the truss chord 9. Based on the pipe diameter of the truss chord 9 and the construction space for the operator, the telescopic guide rod 4 slides in the conduit 210 to adjust the position of the basket 3. The two conduits 210 are connected by the first frame rod 220 and the second frame rod 230. A welding machine storage platform can be set up on the frame formed by the conduit 210, the first frame rod 220 and the second frame rod 230, and the welding machine parts can be placed on the storage platform.

[0075] like Figure 7 As shown, in one embodiment, one end of the first frame rod 220 is provided with a connecting end plate 6, the connecting end plate 6 is provided with a nut 610, the fixed support 1 is provided with an elongated hole 120, and a bolt 7 for connecting with the nut 610 is inserted into the elongated hole 120.

[0076] The working principle and beneficial effects of the above technical solution are as follows: The connecting end plate 6 is provided with a through hole, and a nut 610 is welded at the through hole. The nut 610 can be an M20 nut. The connecting end plate 6 is installed with the fixed support 1, and the bolt 7 is connected to the nut 610 after passing through the elongated hole 120. The bolt 7 can be an M20 high-strength bolt. The elongated hole 120 is set to adjust the upper and lower installation position of the connecting end plate 6 so that the telescopic guide 2 can be placed on the truss chord 9. The truss chord 9 can support the telescopic guide 2, so that the telescopic guide 2 is installed firmly.

[0077] like Figure 8 As shown, in one embodiment, the conduit 210 is provided with a plurality of first holes 211 at intervals, the telescopic guide rod 4 is provided with a plurality of second holes 410 at intervals, the two ends of the first hole 211 are provided with reinforcing washers 212, and the fixing member 5 passes through the first hole 211 and the second hole 410 to limit the connection between the conduit 210 and the telescopic guide rod 4.

[0078] Furthermore, the fixing element 5 is a U-shaped clip, and the U-shaped clips on the two parallel conduits 210 are symmetrically arranged.

[0079] The working principle and beneficial effects of the above technical solution are as follows: Based on the pipe diameter of the truss chord 9 and the limitations of the construction operation space, the position of the telescopic guide rod 4 in the conduit 210 is adjusted, thereby adjusting the position of the basket 3; the conduit 210 and the telescopic guide rod 4 are respectively provided with a first hole 211 and a second hole 410 of φ22mm at intervals of 100mm; the two ends of the first hole 211 on the conduit 210 are provided with reinforcing washers 212; the telescopic guide rod 4 and the telescopic guide frame 2 are fixed by symmetrically placed U-shaped clips (fixing parts 5); the two ends of the U-shaped clips (fixing parts 5) can be inserted into the first hole 211 and the second hole 410, and then the ends of the U-shaped clips (fixing parts 5) are limited by pins to prevent them from falling out.

[0080] like Figures 9-15 As shown, in one embodiment, the basket 3 includes:

[0081] Frame 310 is composed of multiple second frame rods 311;

[0082] Ladder 320 is installed on one side of frame 310;

[0083] Bottom platform 330 is formed by laying a first steel plate mesh at the bottom of frame 310;

[0084] A flip platform 340 is spaced above the bottom platform 330. A rotating shaft 350 connected to the flip platform 340 is provided on the frame 310. A baffle 360 ​​is provided on the frame 310 opposite to the rotating shaft 350. When the flip platform 340 is rotated to a horizontal position, it overlaps with the baffle 360.

[0085] The working principle and beneficial effects of the above technical solution are as follows: The frame 310 is formed by welding the second frame rods 311 arranged in multiple directions, and a ladder 320 is set on one side of the frame 310 to facilitate the movement of operators; the flip platform 340 is formed by laying a second steel mesh on the erected support frame.

[0086] Based on the height requirements of the construction operation space, the folding and unfolding platform 340 is determined by using the pivot 350 and baffle 360 ​​set on the second frame pole 311;

[0087] By setting up a flip-up platform 340 within the frame 310, the height of the construction operation platform can be adjusted twice, providing operators with a better working space during the welding of the pipe truss structure to meet the requirements of welding operations. The retractable design and the built-in flip-up platform 340 can be adjusted according to the requirements of the working space, providing a better working space and ensuring the requirements of welding operations.

[0088] like Figures 16-22As shown, in one embodiment, a stabilizing support 8 is provided between the frame 310 and the truss chord 9, the stabilizing support 8 comprising:

[0089] Connector 810 is used to connect to the second frame rod 311 of frame 310;

[0090] Connecting rod 820, one end of which is rotatably connected to connecting piece 810;

[0091] A connecting tube 830 is sleeved to the other end of a connecting rod 820; the outer wall of the connecting tube 830 is provided with an external thread 831 and a limiting slide bar 832 extending axially, the external thread 831 is provided on the side of the limiting slide bar 832 near the connector 810; the end of the connecting tube 830 near the external thread 831 is provided with a plurality of locking pieces 840.

[0092] The support block 850 has an insertion hole at one end for inserting into the connecting pipe 830, and the other end abuts against the truss chord 9. The insertion hole has a first groove 851 corresponding to the limiting slide bar 832.

[0093] A limiting cylinder 860 is sleeved on the outside of the connecting pipe 830, and a spring 870 is provided between the limiting cylinder 860 and the support block 850; a second sliding groove 862 corresponding to the limiting slide bar 832 is provided inside the limiting cylinder 860.

[0094] The locking cylinder 880 has an internal thread 881 corresponding to the external thread 831 and a tapered hole corresponding to the locking piece 840 arranged sequentially along the axial direction inside.

[0095] The first ratchet 861 and the second ratchet 882 are respectively located at the ends where the limiting cylinder 860 and the locking cylinder 880 are connected.

[0096] Furthermore, the locking piece 840 is evenly arranged along the circumference of the connecting tube 830, and the outer side of the end of the locking piece 840 is provided with an elastic protrusion 841.

[0097] The working principle and beneficial effects of the above technical solution are as follows: When the telescopic suspended platform is in use, the baskets 3 on both sides are prone to swaying under force. When the force is large, the telescopic guide rod 4 or the guide tube 210 may bend, making the telescopic suspended platform unstable. In order to improve its stability, a stabilizing support 8 is set between the basket 3 and the truss chord 9 to form an auxiliary support for the telescopic guide rod 4 and the guide tube 210, which can ensure the stability of the telescopic suspended platform and further ensure the construction safety of the operators.

[0098] Considering the ease of installation and disassembly of the stabilizer 8, the connector 810 of the stabilizer 8 is detachably connected to the second frame rod 311 of the frame 310. The position of the connector 810 on the second frame rod 311 is determined according to the diameter of the truss chord 9; when the diameter of the truss chord 9 is small, such as Figure 16 As shown, the connector 810 can be installed on the second frame rod 311 that is inclined in the figure to ensure that the stabilizer 8 provides support for the lower part of the truss chord 9. When the diameter of the truss chord 9 is large, the distance between the frame 310 and the truss chord 9 is small. In this case, the stabilizer 8 can be installed on the second frame rod 311 that is vertically installed on the side close to the truss chord 9.

[0099] During installation, first determine the installation position of the connector 810 based on the diameter of the truss chord 9. Then adjust the angle of the connecting rod 820 and the extension distance of the connecting pipe 830 and the connecting rod 820 so that the support block 850 abuts against the truss chord 9. At this time, the locking cylinder 880 is in an unlocked state, that is, the locking cylinder 880 is not threadedly connected to the connecting pipe 830. After adjustment, screw the locking cylinder 880 towards the side closer to the support block 850 so that the locking cylinder 880 is threadedly connected to the connecting pipe 830. As screwing continues, the tapered hole squeezes the locking piece 840, and the elastic protrusion 841 can abut firmly against the tapered hole, so that the elastic locking piece 840 abuts firmly against the connecting rod 820, and the extension length of the connecting rod 820 and the connecting pipe 830 is firmly fixed.

[0100] When the locking cylinder 880 is screwed toward the side closer to the support block 850, the second ratchet 882 of the locking cylinder 880 interacts with the first ratchet 861 of the limiting cylinder 860, pushing the first ratchet 861 to move axially. Under the limiting action of the limiting slide bar 832, the limiting cylinder 860 is pushed to move linearly toward the side closer to the support block 850. The spring 870 is then compressed, and the spring 870 simultaneously exerts an elastic force on the limiting cylinder 860 and the support block 850, causing the support block 850 to engage with the truss chord 9. The contact is firm, forming a pre-tightening force. The limiting cylinder 860 provides an anti-loosening function for the locking cylinder 880. That is, when the threaded connection between the locking cylinder 880 and the connecting pipe 830 becomes loose, the locking cylinder 880 tends to rotate (this rotation direction is opposite to its rotation direction when it is locked). Under the action of the two ratchet teeth, the locking cylinder 880 is limited to rotation and cannot rotate in this direction, thereby preventing the locking cylinder 880 from loosening. The side of the support block 850 that contacts the truss chord 9 is an arc-shaped surface.

[0101] During construction, the firmness of the connection between the support block 850 and the truss chord 9 is ensured, forming a stable support. Furthermore, the above installation method not only ensures a firm connection between the support block 850 and the truss chord 9, but also provides convenience and flexibility in installation. During disassembly, the frame 310 must first be moved away from the truss chord 9 so that the support block 850 is disengaged from the truss chord 9 before the stable support 8 can be disassembled. In other words, it cannot be disassembled by loosening the locking cylinder 880, further ensuring the stability of the support.

[0102] Furthermore, a pressure sensor is provided on the side of the support block 850 that contacts the truss chord 9 to sense the contact force between the support block 850 and the truss chord 9; the pressure sensor is connected to the control module, which is detachably mounted on the basket 3.

[0103] During the installation of the stabilizer 8, the pressure sensor detects the contact force between the support block 850 and the truss chord 9. The control module then determines whether the contact force meets the support preload requirement. If it does, the installation is in compliance with the requirements; otherwise, the support position needs to be adjusted.

[0104] When the suspended platform is in use, the pressure sensor detects the contact force between the support block 850 and the truss chord 9 in real time. The control module determines whether the contact force is within the pressure threshold. If it is, the suspended platform is in normal use. If not, a warning is issued when the contact force is less than the minimum value of the pressure threshold, and an alarm is issued when the contact force is greater than the maximum value of the pressure threshold.

[0105] When the suspended platform is in use, if the basket body 3 on both sides is subjected to force, causing the telescopic guide rod 4 or the conduit 210 to deform, the lower part of the basket body 3 will rotate towards one side of the truss chord 9, thereby increasing the contact force between the support block 850 and the truss chord 9. During the welding of the tubular truss, the suspended platform may vibrate, which could cause the connector 810 to loosen, reducing the support force of the stabilizer 8 on the truss chord 9. In this case, the contact force detected by the pressure sensor will decrease. Therefore, a pressure threshold is set to judge the change in contact force during the use of the suspended platform. By judging whether the contact force is within the pressure threshold, a warning is issued indicating that the contact between the stabilizer 8 and the truss chord 9 has loosened, and an alarm is issued indicating that the basket body 3, telescopic guide rod 4, or conduit 210 may have deformed, prompting operators to pay attention to safety and ensuring the safety of construction.

[0106] like Figures 23-24 As shown, in one embodiment, the connector 810 includes:

[0107] Two symmetrically arranged slotted fixing parts 811 are provided, and connecting ear plates 812 are provided on both ends of the slot opening of the fixing parts 811. The connecting ear plates 812 of the two fixing parts 811 are connected by a bolt assembly; one of the fixing parts 811 is used to rotatably connect with the connecting rod 820.

[0108] The trapezoidal anti-slip component 813 has an installation groove 814 on the inner side of the groove end of the fixing part 811. The bottom surface of the installation groove 814 is an inclined surface. A space area for installing the trapezoidal anti-slip component 813 is formed between the installation grooves 814 of the two fixing parts 811. The trapezoidal anti-slip component 813 abuts against the surface of the second frame rod 311.

[0109] The working principle and beneficial effects of the above technical solution are as follows: the connector 810 is detachably connected to the second frame rod 311, and the two slotted fixing parts 811 are fastened to the two sides of the symmetrical fasteners of the second frame rod 311, and then the two are locked together by bolt assembly; so that the fixing parts 811 and the surface of the second frame rod 311 are in close contact.

[0110] To increase the friction between the fixing part 811 and the second frame rod 311, a trapezoidal spatial region is formed between the mounting grooves 814 of the two fixing parts 811. The external dimension of the trapezoidal spatial region is smaller than the dimension of the end near the second frame rod 311. A trapezoidal anti-slip member 813 is embedded in this spatial region. When the two fixing parts 811 approach each other, the inclined surface of the mounting groove 814 presses against the trapezoidal anti-slip member 813, so that the trapezoidal anti-slip member 813 with elastic deformation capability is in close contact with the second frame rod 311, increasing the friction between the connection with the second frame rod 311 and ensuring the installation stability of the connector 810.

They are used only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.
