[0031] The plug-in assembly includes a plug rod 201, a first elastic member 202, a connecting rod 203, a second elastic member 204, a connecting rope 205 and a clamping block 206; each door frame 1 is provided with a plurality of rectangularly distributed plug holes 1005; each pedal 3 is movably connected with a plug rod 201; the plug rod 201 is arranged in a U shape; each plug rod 201 is inserted into the corresponding plug hole 1005; each plug rod 201 is provided with a groove 20101; each plug rod 201 is fixedly connected with two front-to-back symmetrical first elastic members 202, and the first elastic member 202 is a spring; each Each first elastic member 202 is fixedly connected to the corresponding pedal 3; each insertion rod 201 is slidably connected to a connecting rod 203; each connecting rod 203 is provided with a notch 20301; two second elastic members 204 that are symmetrical in front and back are fixedly connected between each connecting rod 203 and the corresponding insertion rod 201, and the second elastic member 204 is a spring; each connecting rod 203 is fixedly connected to two connecting ropes 205 that are symmetrical in front and back; each insertion rod 201 is rotatably connected to two blocking blocks 206 that are symmetrical in front and back through a torsion spring; each connecting rope 205 is fixedly connected to the corresponding blocking block 206.

[0032] Each climbing pole 1001 is provided with a plurality of anti-slip strips 1003 .

[0033] Furthermore, in order to enhance the calibration and alignment effect when the insertion rod 201 is inserted, so as to facilitate the staff to install the pedal 3, each insertion hole 1005 is configured to have a flared structure.

[0034] When using the portal scaffold, the staff first passes the lower part of the diagonal rod 2 through the corresponding locking pins 1002 to fix the diagonal rod 2 on the portal frame 1, and then fixes the upper part of the diagonal rod 2 to the movable sleeve 101 through the locking rod 102. By adjusting the height of the movable sleeve 101 on the portal frame 1, the inclination of the diagonal rod 2 is adjusted, and the vertical distance between the upper and lower ends of the diagonal rod 2 is changed, thereby realizing the adjustment of the distance between the two portal frames 1, which is conducive to adapting to working areas of different widths and improving the versatility and adaptability of the portal scaffold.

[0035] After the door frame 1 is adjusted, if the combined length of the two pedals 3 is the same as the width between the two door frames 1, the staff will lift the pedal 3 and hold the lower side of the plug rod 201 and the connecting rod 203 with their hands. Then the staff will press the connecting rod 203 toward the plug rod 201 with their palms and compress the second elastic member 204 at the same time, so that the connecting rod 203 pulls the connecting rope 205, driving the block 206 parallel to the connecting rod 203 to rotate to be perpendicular to the connecting rod 203 and compress the torsion spring between the block 206 and the plug rod 201. Then the two arms of the staff will move closer to each other. The two plug rods 201 are squeezed toward the opposite sides, compressing the first elastic member 202 at the same time, and then the staff aligns the plug rod 201 with the socket 1005 of the corresponding height, and then the staff releases the squeezing of the two plug rods 201, so that the two plug rods 201 are inserted into the socket 1005 of the corresponding height, thereby installing the pedal 3 on the door frame 1. After the plug rod 201 is inserted into the socket 1005, the staff releases the pressure on the connecting rod 203 with the palm of their hand, so that the connecting rod 203 stops pulling the connecting rope 205, and then the block 206 rebounds and rotates to the position as shown in the figure under the elastic force of the torsion spring. Figure 5 In the state shown, the insertion rod 201 is fixed inside the socket 1005, thereby enhancing the fixing effect of the insertion rod 201 on the pedal 3, preventing the pedal 3 from loosening and falling off, and avoiding the pedal 3 from shifting or falling, thereby ensuring the personal safety of the staff. At the same time, when the staff grasps the insertion rod 201 and the lower side of the connecting rod 203, the thumb of the staff can be inserted into the groove 20101, and the other fingers can be inserted into the notch 20301, which is convenient for the staff to hold the insertion rod 201 and the connecting rod 203, and at the same time, it is convenient for the staff to apply force.

[0036] If the door frame 1 is adjusted, the combined length of the two pedals 3 is less than the width between the two door frames 1. When the staff member grasps the lower side of the insertion rod 201 and the connecting rod 203, the staff member first presses the connecting rod 203 toward the insertion rod 201 with his palm, so that the block 206 rotates to be perpendicular to the connecting rod 203, and then the two arms of the staff member move away from each other to drive the two insertion rods 201 to move toward the opposite sides. At this time, the pedal 3 is pulled by the first elastic member 202 to slide on the extension plate 4, and the extension plate 4 is unfolded to wait for the insertion. When the rod 201 is inserted into the socket 1005 of the corresponding height, the staff releases the pressure on the connecting rod 203 with his palm, so that the block 206 is reset and stuck inside the socket 1005. At this time, the pedal 3 and the extension plate 4 together form a working platform. If the pedal 3 has been installed on the door frame 1 and the door frame 1 needs to be adjusted, at this time, as the distance between the two door frames 1 increases, the door frame 1 will pull the pedal 3 to slide on the extension plate 4 through the insertion rod 201, the first elastic member 202 and the block 206 to adapt to the adjustment of the door frame 1.

[0037] When adjusting to increase the width of the door frame 1, the upper end of the diagonal brace 2 descends on the door frame 1 along with the movable sleeve 101, and the distance between the upper end and the lower end of the diagonal brace 2 is shortened. At this time, the locking rod 104 is slid in the slide groove 3002, driving the upper end of the reinforcement rod 103 to slide in the slide groove 3002 along with the adjustment of the upper end of the diagonal brace 2. After the adjustment of the upper end of the diagonal brace 2 is completed, the locking rod 104 is tightened to fasten the reinforcement rod 103 to the pedal 3. While improving the versatility and adaptability of the portal scaffolding, the fixing effect between the door frame 1 and the pedal 3 is enhanced, preventing the fixing effect of the door frame 1 from being reduced due to the shortening of the distance between the upper end and the lower end of the diagonal brace 2, and avoiding the door frame 1 from loosening and causing the pedal 3 to shift or fall, thereby improving the protection effect on the staff.

[0038] The present invention adjusts the height of the pedal 3 on the door frame 1 by means of the insertion rod 201, thereby realizing convenient adjustment of the pedal 3, solving the problem that the height of the pedal 3 is fixed and cannot be conveniently adjusted, which makes it inconvenient for workers to perform construction operations at a position flush with the height of the pedal 3. The specific process is as follows:

[0039] When the staff is constructing the high-rise area, it is necessary to stack the gantry scaffolds layer by layer to construct the high-rise area. When the construction position is close to the pedal 3, it is inconvenient for the staff to perform construction operations due to the height limitation of the pedal 3. At this time, the staff opens the rotating plate 3001, climbs down from the hole opened by the rotating plate 3001 to the pedal 3 of the next layer through the climbing rod 1001, and through the rotation of the rotating plate 3001 on the pedal 3, a passage for people to pass through is opened on the pedal 3, so that the staff can pass through the two gantry scaffolds. 1, so that the staff can climb up or down in the area between the two door frames 1, so as to prevent the staff from climbing outside the two door frames 1 and preventing the staff from falling. When the staff climbs on the climbing bar 1001, the anti-slip strip 1003 increases the friction between the staff's hands and feet and the climbing bar 1001 to prevent slipping, thereby further improving the protection effect for the staff. When the staff climbs to the pedal 3 of the next layer, the locking rod 104 is first released to fix the reinforcement rod 103, so that the reinforcement rod 103 can slide in the slide groove 3002. The staff then grasps the upper layer of the plug rod 201 and the connecting rod 203 by hand, and presses the upper layer of the connecting rod 203 toward the plug rod 201, so that the connecting rope 205 pulls the block 206 to release the locking of the plug rod 201, and then takes the upper layer of the plug rod 201 out of the corresponding socket 1005, and adjusts the pedal 3 to the required height for construction, and at the same time makes the locking rod 104 slide in the slide groove 3002 as the pedal 3 rises and falls, and then inserts the plug rod 201 into the corresponding socket 1005, and The block 206 is used to lock and fix the insertion rod 201 again. After the height adjustment of the pedal 3 is completed, the locking rod 104 is used to fix the reinforcement rod 103 again. The staff returns to the pedal 3 of the upper layer through the channel opened by the rotating plate 3001, and performs construction on the position that was originally flush with the pedal 3, thereby realizing convenient and fast adjustment of the height of the pedal 3. There is no need to use other auxiliary equipment for construction operations, which improves the working requirements of the pedal 3 at different heights, allowing operators to work at the most suitable height, thereby improving work efficiency and safety. Example 2

[0040] On the basis of Example 1, Figure 1 , Figure 2 and Figure 4-Figure 6 As shown, it also includes a limit rod 301; four limit rods 301 that are symmetrical front and back are fixed to each door frame 1; each two adjacent limit rods 301 in the front and back form a group; each group of limit rods 301 is located on the left and right sides of the corresponding insertion hole 1005.

[0041] Furthermore, in order to further enhance the calibration and alignment effect when the insertion rod 201 is inserted, each limiting rod 301 is inclined toward the front and rear sides of the insertion hole 1005, and the space between two adjacent limiting rods 301 is flared.

[0042] It also includes a cushion block 302 ; a cushion block 302 is fixedly connected to the lower side of each insertion hole 1005 ; and each cushion block 302 is located between two adjacent limiting rods 301 .

[0043] A blocking piece 303 is also included; a blocking piece 303 is fixedly connected to the upper side of each fixing hole 1004 .

[0044] After the staff adjusts the pedal 3 to the required height for construction and takes the rod 201 out of the socket 1005, since the pedal 3 is made of metal plates to meet the strength requirements of the staff during construction, the weight of the pedal 3 is relatively large. When the staff adjusts the height of the pedal 3, the pedal 3 deflects due to its heavy weight, and the rod 201 cannot be accurately inserted into the corresponding socket 1005. The specific solution process is as follows:

[0045] After the staff takes the rod 201 out of the socket 1005, the front and rear sides of the rod 201 taken out of the socket 1005 are blocked and limited by the limit rod 301, and then the corners of the two pedals 3 are limited, so that the pedals 3 can only be raised and lowered within the limit rod 301, to prevent the rod 201 from being deflected along with the pedal 3 after being taken out due to its heavy weight, to avoid the rod 201 from being unable to be accurately inserted into the corresponding socket 1005, thereby realizing convenient and quick adjustment of the height of the pedal 3.

[0046] After the staff adjusts the height of the pedal 3 and takes the rod 201 out of the socket 1005, due to the heavy weight of the pedal 3, the staff inserts the thumb into the groove 20101 and the other fingers into the notch 20301, which is helpful to enhance the supporting and fixing effect of the pedal 3 and reduce the slipping of the pedal 3 during adjustment. When the staff's hand on the pedal 3 slips, the rod 201 falls between the two limit rods 301 with the pedal 3, and the pad 302 blocks and supports the rod 201 when the pedal 3 falls, preventing the pedal 3 from slipping and falling and injuring the staff, thereby enhancing the protection effect on the staff when adjusting the height of the pedal 3.

[0047] When the worker stands on the pedal 3 to perform construction operations, the baffle 303 is used to block impurities such as cement mortar that fall downward, preventing the impurities from falling onto the fixing hole 1004, thereby preventing the fixing hole 1004 from being blocked and making it impossible to adjust the width of the door frame 1, thereby improving the protection effect of the door frame 1 during construction.

[0048] While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.The scope of the following claims is to be accorded the broadest interpretation so as to encompass all such modifications and equivalent structures and functions.
