As shown in fig. 6, a first stop pin 31 is located at the bottom of the upper tower section 3, which is radially telescopically arranged to extend into or out of a first stop hole 21 on the inner wall of the lower tower section 2.

Preferably, the first limiting pins 31 and the first limiting holes 21 are multiple and in one-to-one correspondence, and the first limiting holes 21 are circumferentially arranged at intervals at the bottom of the upper tower section 3, so that the fixed relationship between the upper tower section 3 and the lower tower section 2 reaching the initial position is more stable.

Of course, in other alternative embodiments, the first stop pin may be provided inside the lower tower section 2 and the first stop hole may be provided on a corresponding inner wall of the upper tower section 3. The utility model is not limited in this regard.

Further, the step of fixing the upper tower section 3 and the lower tower section 2, which are lifted to the preset positions, in step S60 may specifically be a manner of fixing the upper tower section and the lower tower section with each other by using a limiting pin.

In some embodiments, as shown in fig. 3-12, the upper tower section 3 includes a first barrel and a first bracket 301, the first bracket 301 being located at the bottom of the first barrel and protruding outwardly relative to the first barrel. The lower tower section 2 comprises a second cylinder and a second bracket 201, the second bracket 201 being located at the top of the second cylinder and protruding inwards relative to the second cylinder. The first bracket 301 is provided with a first lifting hole, and the second bracket 201 is provided with a second lifting hole. The first bracket 301 is vertically opposite to the second bracket 201, and the first lifting duct is vertically opposite to the second lifting duct.

In step S40, as shown in fig. 7 and 8, the climbing rib 4 sequentially passes through the second lifting hole of the second bracket 201 and the first lifting hole of the first bracket 301 from top to bottom, and the top end of the climbing rib 4 is anchored at the top of the second bracket 201.

Further, as shown in fig. 12, in step S60, when the upper tower section 3 reaches the preset position, the top of the first bracket 301 abuts against the bottom of the second bracket 201, that is, the top of the upper tower section 3 located at the preset position abuts against the bottom of the second bracket 201, so that the second bracket 201 can accurately position the climbing position of the upper tower section 3.

Preferably, as shown in fig. 9, the climbing ribs 4 in step S40 are plural, and the plural climbing ribs 4 are circumferentially spaced apart. Correspondingly, the first lifting pore canals and the second lifting pore canals are multiple and correspond to each other one by one, and after the climbing rib 4 sequentially passes through one first lifting pore canal and the corresponding second lifting pore canal from top to bottom along the vertical direction, the bottom end is anchored on the tower foundation 1, and the top end is anchored at the top of the lower tower section 2. So can improve the stability of upper tower section 2 in the climbing process, guarantee the straightness that hangs down of upper tower section 2. Correspondingly, as shown in fig. 9, in step S50, climbing devices 5 are installed at corresponding positions of each climbing rib 4, and each climbing device 5 operates synchronously, maintains the same climbing rate, and pushes the ascending tower section 3 to ascend together.

Optionally, the climbing rib 4 is a steel strand, so that the strength of the steel strand is high, and the construction safety can be ensured.

In the embodiment shown in fig. 1-14, the climbing device 5 is optionally a climbing jack, which is a penetrating jack, characterized in that it can climb up along the climbing rib 4. Specifically, the climbing device 5 is fixed below the first bracket 301 and is fixed opposite to the upper tower section 3, and the steel strand passes through the climbing jack as a wire of the climbing jack.

The power equipment of the climbing jack is preferably a hydraulic pump station, and the heavy object is lifted (continuously translated) or lowered in proper amount through the relative motion of the piston of the climbing jack and the oil cylinder along the steel stranded wire. The principle is that the prestress anchorage technology and the hydraulic jack technology are organically combined, the steel stranded wires are anchored through the anchorage, and then the flow and the oil pressure (driving devices such as a proportional valve and a reversing valve) output by a hydraulic pump station are intensively controlled by a computer, so that a piston of a climbing jack is driven to stretch or shrink (a displacement sensor device), a component is driven to lift, fall or continuously translate, and the integral synchronous lifting (translation) and proper lowering of a large component are realized.

The initial position of the climbing device 5 is low, and the installation is convenient. In order to facilitate the entry of the staff into the lower tower section 2 for the installation of the climbing device 5, a tower door may be reserved at the bottom of the lower tower section 2.

In some embodiments, after the upper tower section 3 reaches the preset position and the upper tower section 3 is fixed in step S60, the bottom of the upper tower section 3 needs to be further connected to the top of the lower tower section 2, and the connection manner between the bottom of the upper tower section 3 and the top of the lower tower section 2 may be various, alternatively, an anchor bolt connection or a post-cast strip connection may be adopted.

Step S60 thus also comprises, when the upper tower section 3 reaches the preset position, the bottom of the upper tower section 3 being connected to the top of the lower tower section 2 by means of anchor bolts or by means of post-cast strips.

Specifically, in some embodiments, the bottom of the upper tower section 3 is connected with the top of the lower tower section 2 by adopting an anchor bolt, and the anchor bolt penetrates through the second bracket 201 of the lower tower section 2 and the first bracket 301 of the upper tower section 3 to anchor and connect the upper tower section 3 with the lower tower section 2, so that the connection stability of the upper tower section 3 and the lower tower section 2 is ensured, and stronger external force can be resisted.

In other embodiments, the bottom of the upper tower section 3 is connected to the top of the lower tower section 2 with post-cast strips. The post-cast strip is a concrete strip which is reserved in structures such as beams, plates (including foundation plates), walls and the like, has a certain width and is cast after a certain time in order to adapt to the influence of factors such as environmental temperature change, concrete shrinkage, uneven settlement of the structures and the like. Specifically, after the upper tower section 3 is lifted to a preset position, the flange of the upper tower section 3 serves as a bottom plate for pouring a post-pouring strip, the end face of the lower tower section 2 serves as a top plate for pouring the post-pouring strip, the outer wall of the upper tower section 3 and the inner wall of the lower tower section 2 serve as side plates for pouring the post-pouring strip, and therefore the upper tower section 3 and the lower tower section 2 are connected through the post-pouring strip.

It should be noted that, except that the anchoring connection and the post-pouring belt connection are adopted respectively, the two can also be adopted simultaneously, namely, the upper tower section 3 and the lower tower section 2 are anchored and connected first, then the concrete belt is poured, the connection of the two is more stable in a combined mode, stronger external force can be resisted, and the service life of the climbing self-lifting tower 100 can be prolonged.

In some embodiments, the construction process of the climbing self-lifting tower 100 further includes the step of pre-stressing the lower tower segment 2.

In some preferred embodiments, the prestressing of the lower tower section 2 is performed by means of climbing ribs 4, which is performed after the climbing ribs 4 are provided, or after the assembly of the lower tower section 2 with the upper tower section 3 is completed. That is, the climbing rib 4 can prestress the lower tower section 2 as a prestressing rib of the lower tower section 2. The prestress tensioning of the lower tower section 2 may be completed after the climbing rib 4 is provided in step S40, or the prestress tensioning of the lower tower section 2 may be performed by the climbing rib 4 after the assembly is completed in step S60.
