As a specific embodiment of the main material replacing device for the iron tower provided by the invention, a plurality of supporting rods 2 are arranged, and two ends of each supporting rod 2 are respectively provided with a connecting flange 6.

The different branch 2 between accessible flange joint structure connect, and then can be according to actual use condition adjustment bearing structure's length, use the flexibility better.

Referring to fig. 9 to 13, as an embodiment of the device for replacing main materials of an iron tower according to the present invention, a protrusion structure at the middle of the insertion ring groove 404 protrudes from the upper surface of the insertion seat 403.

When the inserting convex ring 8 is inserted into the inserting ring groove 404, the convex structure in the middle of the inserting ring groove 404 is firstly in concave butt joint with the middle of the inserting convex ring 8, so that the subsequent insertion is guided, and the butt joint efficiency is improved; meanwhile, the protruding structure can also be matched with the outer side wall of the inserting ring groove 404 to lock the inserting convex ring 8, so that the inserting convex ring 8 is prevented from being separated from the inserting ring groove 404, and the use reliability and safety are improved.

Referring to fig. 15 and 16, as a specific embodiment of the device for replacing main materials of an iron tower according to the present invention, the inserting seat 403 is further provided with an auxiliary locking structure for locking the lower end of the telescopic supporting member 3, and the auxiliary locking structure includes two rotating rods 10 whose lower ends are respectively hinged to two sides of the inserting seat, two semi-circular-arc-shaped clasps 11 whose outer sides are respectively fixedly connected to the top ends of the two rotating rods 10, and clasp locking members for respectively fixing two ends of the two clasps 11. Whether the two clamping rings 11 are locked or not is controlled by pulling the rotating rod 10, further locking of the lower end part of the telescopic supporting piece 3 can be achieved without changing the structure of the telescopic supporting piece 3, and the inserting convex ring 8 at the lower end of the telescopic supporting piece 3 is further prevented from being separated from the inserting ring groove 404.

Referring to fig. 15 and 16, as a specific embodiment of the iron tower main material replacing device provided by the present invention, the snap ring locking member includes a snap groove disposed at two ends of one snap ring 11, a snap plate disposed at two ends of the other snap ring and adapted to be snap-fitted with the snap groove, a lock hole penetrating through two sides of the snap groove and the snap plate, and a second connecting pin 12 adapted to be inserted into the lock hole, and a second detachable handle 13 is further connected to an upper end of the second connecting pin 12. The snap ring 11 is locked through a pin joint structure, the structure is simple, and the second connecting pin 12 is convenient to assemble and disassemble.

The invention also provides a method for replacing the main material of the iron tower, which comprises the following steps:

fixing an upper clamp 1 on a main material above the main material to be replaced, and fixing a lower clamp 4 on the main material below the main material to be replaced;

connecting and fixing the support rod 2 and the upper clamp 1, and installing a telescopic top support 3 at the lower end of the support rod 2;

mounting the pressure sensing member to the telescopic top bracket 3 or to the lower clamp 4;

the lower end of the telescopic top supporting piece 3 is controlled to extend, the pressure between the telescopic top supporting piece 3 and the lower clamp 4 is obtained in real time through the pressure sensing piece until the lower end of the telescopic top supporting piece 3 is inserted into the specified position of the lower clamp 4 and reaches the specified pressure value;

dismantling the main material to be replaced;

hoisting the new main material to a specified position and installing;

and after the new main material is installed, the lower end of the telescopic top supporting piece retracts to the initial position, and the telescopic top supporting piece 3, the supporting rod 2, the lower clamp 4 and the upper clamp 1 are sequentially detached.

According to the method for replacing the main material of the iron tower, the upper clamp 1 and the lower clamp 4 are fixed on the upper side and the lower side of the main material to be replaced, the support rod 2 and the telescopic supporting piece 3 are supported between the upper clamp 1 and the lower clamp 4, the main material to be replaced can be replaced to play a supporting role, therefore, an operator does not need to consider the problem of structural strength of the position to be replaced, directly detaches the main material to be replaced, installs a new main material lifted in place, and finally detaches the device for replacing the main material of the iron tower. The operation process is simple, the safety is high, and the potential safety hazard of construction is reduced; meanwhile, the construction method does not depend on the ground, has low requirements on the terrain, has wide application range and can improve the operation efficiency.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
