[0030] The present invention will now be further described with reference to the accompanying drawings. Example 1

[0031] like Figures 1-3 As shown, a novel portable standing device for iron towers includes a main tower frame 1 and a support platform 4. An upper inclined rod 2 and a lower inclined rod 3 are fixedly and crosswise along the sides of the main tower frame 1. The support platform 4 is located between the upper inclined rod 2 and the lower inclined rod 3. A shoulder strap 25 is provided along the sides of the support platform 4. A telescopic part 5 is provided at the bottom of the support platform 4. An extension rod 6 is movably installed inside the telescopic part 5. A bidirectional head 8 is fixedly installed at the right end of the extension rod 6. A vertical rod 7 is hinged to the left side of the telescopic part 5. Clamps 9 are provided between the bidirectional head 8 and the upper inclined rod 2 and the lower inclined rod 3, and between the vertical rod 7 and the main tower frame 1 and the lower inclined rod 3. The support platform 4 allows for a horizontal standing posture, facilitating operation by workers.

[0032] For better performance, universal joints are provided between the bidirectional head 8, the vertical rod 7, and the clamp 9. The universal joint connection reduces stress concentration at the connection points and lowers the risk of structural failure due to angular deviations.

[0033] For better performance, the gripper 9 includes a right-angle plate 10 and a claw 11. The right-angle plate 10 has an inner groove 12 in its center, and the claw 11 engages with the inner groove 12. An inner rod 13 is rotatably connected inside the inner groove 12. A clamping screw 14 is located on the side of the inner rod 13 near the claw 11, and the clamping screw 14 is threadedly connected to the claw 11. The claw 11 can be moved by the clamping screw 14.

[0034] In normal use, the extension rod 6 is retracted into the telescopic part 5, and the support platform 4 and vertical rod 7 are folded and placed together. The device is carried to the location where standing work is required via the shoulder strap 25. Preferably, the cross beam of the iron tower or a structurally stable member is selected as the support point (such as the upper inclined rod 2 and lower inclined rod 3 in this application). Adjust the support platform 4 to a horizontal position, and place the vertical rod 7 against the main tower frame 1. Hold the extension rod 6 and bring the bidirectional head 8 close to the intersection of the upper inclined rod 2 and lower inclined rod 3. Pre-clamp each clamp 9 with the main tower frame 1, upper inclined rod 2, and lower inclined rod 3. Rotate the clamping screw 14 to drive the hook 11 to clamp synchronously until the hook 11 is completely attached to the main tower frame 1, upper inclined rod 2, and lower inclined rod 3, ensuring a stable connection between the vertical rod 7 and the main tower frame 1, and between the bidirectional head 8 and the upper inclined rod 2 and lower inclined rod 3. Standing work can then be performed. Example 2

[0035] like Figures 1-5 As shown, a novel portable standing device for iron towers includes a main tower frame 1 and a support platform 4. An upper inclined rod 2 and a lower inclined rod 3 are fixedly and crosswise along the sides of the main tower frame 1. The support platform 4 is located between the upper inclined rod 2 and the lower inclined rod 3. A shoulder strap 25 is provided along the sides of the support platform 4. A telescopic part 5 is provided at the bottom of the support platform 4. An extension rod 6 is movably installed inside the telescopic part 5. A bidirectional head 8 is fixedly installed at the right end of the extension rod 6. A vertical rod 7 is hinged to the left side of the telescopic part 5. Clamps 9 are provided between the bidirectional head 8 and the upper inclined rod 2 and the lower inclined rod 3, and between the vertical rod 7 and the main tower frame 1 and the lower inclined rod 3. The support platform 4 allows for a horizontal standing posture, facilitating operation by workers.

[0036] For better performance, universal joints are provided between the bidirectional head 8, the vertical rod 7, and the clamp 9. The universal joint connection reduces stress concentration at the connection points and lowers the risk of structural failure due to angular deviations.

[0037] For better performance, the gripper 9 includes a right-angle plate 10 and a claw 11. The right-angle plate 10 has an inner groove 12 in its center, and the claw 11 engages with the inner groove 12. An inner rod 13 is rotatably connected inside the inner groove 12. A clamping screw 14 is located on the side of the inner rod 13 near the claw 11, and the clamping screw 14 is threadedly connected to the claw 11. The claw 11 can be moved by the clamping screw 14.

[0038] For better results, a lifting assembly is provided between the vertical rod 7 and the telescopic part 5. The lifting assembly includes a guide rail 15 and a slide 16. The guide rail 15 is fixedly installed on the surface of the vertical rod 7, and the slide 16 is connected to the telescopic part 5 through a hinge block 17. The slide 16 is engaged with the outside of the guide rail 15.

[0039] For better performance, both the guide rail 15 and the slide 16 have a "T" shape inside. This shape prevents the slide 16 from sliding off the outside of the guide rail 15 during movement.

[0040] For better performance, the guide rail 15 is provided with a limiting hole 18, and the slide 16 is provided with a limiting seat 19 on its outer side. The mechanical locking mechanism between the guide rail limiting hole 18 and the insertion rod 20 prevents the slide 16 from sliding accidentally and ensures the safety of workers at height.

[0041] For better results, the limiting seat 19 is provided with a plug rod 20, the plug rod 20 is provided with a baffle 21 in the middle, the baffle 21 is provided with a limiting spring 22 between the limiting seat 19, and the plug rod 20 is provided with a pull ring 23 at the outer end.

[0042] In another embodiment, the lifting assembly is preferably used such that, when the relative height between the support platform 4 and the vertical rod 7 needs to be adjusted, the pull ring 23 on the outside of the slide 16 is hooked with a finger and pulled outward until the baffle 21 abuts against the inner wall of the limiting seat 19, confirming that the insertion rod 20 has completely exited the guide rail limiting hole 18. At this time, the slide 16 can slide freely. While keeping the pull ring 23 pulled outward, the telescopic part 5 is pushed up and down to move the slide 16 along the guide rail 15. Sliding slowly avoids rapid impact that could deform the guide rail 15. After reaching the predetermined height position, the pull ring 23 is released, and the limiting spring 22 pushes the baffle 21, causing the insertion rod 20 to insert into the predetermined limiting hole 18. At this time, the position of the slide 16 and the guide rail 15 is fixed, and the relative height between the support platform 4 and the vertical rod 7 is also fixed. Example 3

[0043] like Figures 1-9 As shown, a novel portable standing device for iron towers includes a main tower frame 1 and a support platform 4. An upper inclined rod 2 and a lower inclined rod 3 are fixedly and crosswise along the sides of the main tower frame 1. The support platform 4 is located between the upper inclined rod 2 and the lower inclined rod 3. A shoulder strap 25 is provided along the sides of the support platform 4. A telescopic part 5 is provided at the bottom of the support platform 4. An extension rod 6 is movably installed inside the telescopic part 5. A bidirectional head 8 is fixedly installed at the right end of the extension rod 6. A vertical rod 7 is hinged to the left side of the telescopic part 5. Clamps 9 are provided between the bidirectional head 8 and the upper inclined rod 2 and the lower inclined rod 3, and between the vertical rod 7 and the main tower frame 1 and the lower inclined rod 3. The support platform 4 allows for a horizontal standing posture, facilitating operation by workers.

[0044] For better performance, universal joints are provided between the bidirectional head 8, the vertical rod 7, and the clamp 9. The universal joint connection reduces stress concentration at the connection points and lowers the risk of structural failure due to angular deviations.

[0045] For better performance, the gripper 9 includes a right-angle plate 10 and a claw 11. The right-angle plate 10 has an inner groove 12 in its center, and the claw 11 engages with the inner groove 12. An inner rod 13 is rotatably connected inside the inner groove 12. A clamping screw 14 is located on the side of the inner rod 13 near the claw 11, and the clamping screw 14 is threadedly connected to the claw 11. The claw 11 can be moved by the clamping screw 14.

[0046] For better results, a lifting assembly is provided between the vertical rod 7 and the telescopic part 5. The lifting assembly includes a guide rail 15 and a slide 16. The guide rail 15 is fixedly installed on the surface of the vertical rod 7, and the slide 16 is connected to the telescopic part 5 through a hinge block 17. The slide 16 is engaged with the outside of the guide rail 15.

[0047] For better performance, both the guide rail 15 and the slide 16 have a "T" shape inside. This shape prevents the slide 16 from sliding off the outside of the guide rail 15 during movement.

[0048] For better performance, the guide rail 15 is provided with a limiting hole 18, and the slide 16 is provided with a limiting seat 19 on its outer side. The mechanical locking mechanism between the guide rail limiting hole 18 and the insertion rod 20 prevents the slide 16 from sliding accidentally and ensures the safety of workers at height.

[0049] For better results, the limiting seat 19 is provided with a plug rod 20, the plug rod 20 is provided with a baffle 21 in the middle, the baffle 21 is provided with a limiting spring 22 between the limiting seat 19, and the plug rod 20 is provided with a pull ring 23 at the outer end.

[0050] For better performance, the support platform 4 is equipped with an extension assembly, which includes an extension plate 24. The extension plate 24 is movably engaged with the support platform 4 via a connecting rod 26. An extension spring 27 is provided between the connecting rod 26 and the support platform 4. A drive rack 28 is provided on the side of the support platform 4. A full gear 29 is meshed on the side of the drive rack 28. A driven rack 30 is meshed below the full gear 29. A half gear 31 is meshed above the driven rack 30. A lever 32 is fixedly provided on the outside of the half gear 31.

[0051] For better performance, an extension screw 33 is provided on the outer side of the support platform 4. A handle 34 is provided at the end of the extension screw 33, and a sleeve 35 is screwed onto the outer side of the extension screw 33. The sleeve 35 passes through the support platform 4 and is fixedly connected to the drive rack 28. The thread adjustment of the extension screw 33 and the sleeve 35 can precisely control the displacement of the drive rack 28, adapting to the platform area requirements of different working scenarios.

[0052] A method for using a novel portable tower standing device includes the following steps: Step 1: Before use, prepare the support platform 4 to be used, confirm the position of the tower to be installed, and check whether the support platform 4, telescopic part 5, clamp 9 and other components are intact and can work normally. Step 2: Climb the tower to the standing position using the carrying device 25, place the support platform 4 between the upper inclined bar 2 and the lower inclined bar 3, adjust the position of the vertical bar 7, adjust the length of the extension bar 6, fix the vertical bar 7 to the main tower frame 1 and the lower inclined bar 3 using the clamp 9, fix the bidirectional head 8 to the upper inclined bar 2 and the lower inclined bar 3 using the clamp 9, and then you can start standing work; Step 3: When it is necessary to increase the standing area, drive the extension plate 24 to move by turning the handle 34. The extension plate 24 extends out from inside the support platform 4. After the position of the extension plate 24 is stable, the standing working area can be expanded. Step 4: After the work is completed, retract the extension plate 24 into the support platform 4, release the locking effect of each clamp 9, organize and store the device, and retrieve the tools and equipment.

[0053] In another embodiment, the extension component is preferably used to increase the area of ​​the support platform 4 during use, in order to improve work efficiency and expand the work area. During use, rotating the handle 34 causes the extension screw 33 to rotate. Since the sleeve 35 is screwed onto the outside of the extension screw 33 and is fixedly connected to the drive rack 28 through the support platform 4, the rotation of the extension screw 33 drives the sleeve 35 to move linearly, thereby moving the drive rack 28. The movement of the drive rack 28 causes the full gear 29 to rotate, which in turn causes the driven rack 30 to move. The driven rack 30 then causes the half gear 31 to rotate, thereby adjusting the extension length of the extension plate 24 via the lever 32 to meet the area requirements of the support platform in different work scenarios. When the extension plate 24 needs to be retracted after use, rotating the handle 34 in the opposite direction releases the lever 32 from limiting the extension plate 24. Under the action of the extension spring 27, the extension plate 24 will automatically retract into the support platform 4.
