[0038] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0039] Example 1:

[0040] See Figures 1-10 A tower-type concrete placing boom rotating platform lifting mechanism includes a lifting frame 200 and a lifting assembly 500. The lifting frame 200 is used to be installed on a rotating platform 100. The rotating platform 100 is provided with a first channel 111 and a second channel 121. The lifting assembly 500 is installed inside the lifting frame 200 and is located above the first channel 111. The lifting assembly 500 is used to push down the tower cylinder located in the first channel 111 to lift the rotating platform 100 and the lifting frame 200.

[0041] In this embodiment, the lifting frame 200 includes guide posts 240. Two guide posts 240 are arranged longitudinally, and their slots are respectively installed on the upper sides of the first channel 111. Positioning holes 245 are provided on the guide posts 240.

[0042] The lifting assembly 500 includes two lifting cylinders 520. Each lifting cylinder 520 has a limiting block 521 at its cylinder body end, and a limiting hole 522 on the limiting block 521. The two lifting cylinders 520 are movably mounted in the slots of the guide columns 240 on both sides, with the piston rod end of the lifting cylinder 520 facing downwards. A pin 430 passes through the limiting hole 522 and the positioning hole 245 to connect the lifting cylinder 520 to the guide column 240.

[0043] When performing jacking operations, see Figure 1 The rotating platform 100 is mounted on the tower via the first channel 111, and the lower end of the tower is fixed to the ground concrete foundation. A locking mechanism 600 is installed on the lower side of the rotating platform 100 located in the first channel 111.

[0044] When the piston rods of the two lifting cylinders 520 extend downwards simultaneously, they abut against the top of the tower, at which point the locking mechanism 600 is released from its lock on the tower. As the piston rods of the lifting cylinders 520 extend further, the reaction force lifts the rotating platform 100 and the lifting frame 200. Once lifted into position, the locking mechanism 600 is locked back into the tower.

[0045] In this embodiment, see Figure 1 , 2 3. The lifting frame 200 also includes a main frame 210, guide columns 240, and track beams 260, all connected to the main frame 210. The main frame 210, located above the track beams 260, has a first extension frame 220 at one end and a second extension frame 250 at the other end. A connecting plate 230 is fixed to the top of the first extension frame 220, and the top of the second extension frame 250 is connected to the connecting plate 230. The connecting plate 230 is used to install the tie rods for traction of the lifting boom and counterweight boom.

[0046] See Figure 9 , 10 The rotating platform 100 includes a first rotating body 110 and a second rotating body 120. A first channel 111 is located on the first rotating body 110, and a second channel 121 is located on the second rotating body 120. A first connecting seat 112 extends outward from one side of the first rotating body 110, and a second connecting seat 122 extends outward from one side of the second rotating body 120. The first connecting seat 112 and the second rotating body 120 are connected and fixed by a pin or bolt. A first hinge seat 101 is provided on the side of the first rotating body 110 opposite to the first connecting seat 112, and the first hinge seat 101 is used to install the lifting arm. A second hinge seat 102 is provided on the side of the second rotating body 120 opposite to the second connecting seat 122, and the second hinge seat 102 is used to install the counterweight arm. Multiple mounting seats 103 are installed on the upper side of the first rotating body 110 and the second rotating body 120. The mounting seats 103 are used for detachably mounting the lifting frame 200.

[0047] Example 2:

[0048] In this embodiment, a tower-type concrete placing boom rotating platform lifting mechanism includes a lifting frame 200 and a lifting assembly 500. The lifting frame 200 is used to be installed on a rotating platform 100. The rotating platform 100 is provided with a first channel 111 and a second channel 121. The lifting assembly 500 is installed inside the lifting frame 200 and is located above the first channel 111. The lifting assembly 500 is used to push down the tower section 1 located in the first channel 111 to lift the rotating platform 100 and the lifting frame 200.

[0049] The position of the lifting assembly 500 mounted on the lifting frame 200 can be adjusted up and down, thereby reducing the length of the lifting cylinder 520 and the overall height of the lifting frame 200.

[0050] Specifically, see Figures 3-7 The lifting frame 200 includes guide posts 240. Two guide posts 240 are arranged longitudinally, and their slots are respectively installed on the upper sides of the first channel 111. Multiple positioning holes 245 are provided on the guide posts 240 along the height direction.

[0051] The lifting assembly 500 includes two lifting cylinders 520. Each lifting cylinder 520 has a limiting block 521 at its cylinder body end, and a limiting hole 522 on the limiting block 521. The two lifting cylinders 520 are movably mounted in the slots of the guide columns 240 on both sides, with the piston rod end of the lifting cylinder 520 facing downwards. In use, a pin 430 passes through the limiting hole 522 and one of the positioning holes 245 to connect the lifting cylinder 520 to the guide column 240.

[0052] By inserting the pin 430 into the positioning holes 245 at different heights, the lifting cylinder 520 is installed at different heights on the guide post 240.

[0053] When the jacking operation begins, see Figure 1 Since the tower section on the upper side of the rotating platform 100 is relatively high, the lifting assembly 500 is installed at the upper end of the guide column 240. Each lifting height of the lifting assembly 500 is equal to the stroke length of the lifting cylinder 520. After the rotating platform 100 is lifted by one stroke length, the height of the tower section on the upper side of the rotating platform 100 is reduced by one stroke length. Then, the lifting assembly 500 is installed at the guide column 240 and reduced by one stroke length, thus gradually lifting the rotating platform 100 in multiple stages.

[0054] Example 3:

[0055] Based on Example 1 or Example 2, see Figure 7The lifting assembly 500 also includes a balance beam 510, which is detachably mounted on the piston rod ends of the two lifting cylinders 520; the two ends of the balance beam 510 are slidably mounted in the slots of the guide columns 240 on both sides.

[0056] The two ends of the balance beam 510 are slidably installed in the slots of the guide columns 240 on both sides, so that the balance beam 510 can press down on the tower in a balanced manner, thereby improving the stability of the jacking.

[0057] In this embodiment, see Figure 7 The top two sides of the balance beam 510 are respectively fixed with connecting lugs 511, and the piston rod end of the lifting cylinder 520 is fixedly installed with an ear ring. The connecting lugs 511 and the ear rings are detachably connected by a pin. This facilitates the installation and removal of the balance beam 510.

[0058] Furthermore, the lifting assembly 500 also includes an extension frame 530, which is detachably mounted on the underside of the balance beam 510. By providing the extension frame 530, the downward travel of the lifting assembly 500 is increased, reducing the number of times the lifting assembly 500 needs to be adjusted in height.

[0059] Specifically, a flange ring is fixed to the inner wall of the top of the tower, and the bottom of the extension frame 530 can be connected and fixed to the flange ring at the top of the tower by connecting bolts 531.

[0060] In this embodiment, connecting ear seats are also fixedly connected to both sides of the bottom of the balance beam 510, and an ear ring is fixedly connected to the top of the extension frame 530. The connecting ear seats and the ear ring are detachably connected by a pin.

[0061] After the lifting cylinder 520 lifts the cylinder to a certain height by one stroke, the locking mechanism 600 locks with the tower. Then the piston rod of the lifting cylinder 520 retracts, and the extension frame 530 is installed on the lower side of the balance beam 510, so that the lifting operation can be performed again.

[0062] Example 4:

[0063] Based on Embodiment 2 or Embodiment 3, in order to facilitate the insertion of the pin 430 when adjusting the height of the lifting cylinder 520.

[0064] See Figure 1 , 3 8. On the guide post 240, a plug-in pin mechanism 400 is installed at the position corresponding to the positioning hole 245.

[0065] Specifically, the insertion / removal pin mechanism 400 includes a support base 410 and an insertion / removal cylinder 420. The support base 410 is fixedly connected to the guide post 240, and the insertion / removal cylinder 420 is fixedly mounted on the support base 410. Each piston rod end of the insertion / removal cylinder 420 is equipped with a pin 430. A guide ring 440 is installed on the support base 410 at the position of the pin 430, and the pin 430 slides through the guide ring 440. The insertion / removal cylinder 420 is used to control the extension and retraction of the pin 430, and the guide ring 440 is used to guide the pin 430.

[0066] During installation, the support base 410 and the guide post 240 are fixed by welding or bolts, and the mounting seat on the insertion / removal cylinder 420 is bolted to the support base 410. The piston rod end of the insertion / removal cylinder 420 is threadedly engaged with one end of the pin 430, and the other end of the pin 430 is a conical head. When the limiting hole 522 is aligned with the positioning hole 245, the piston rod end of the insertion / removal cylinder 420 extends, inserting the pin 430 into the corresponding limiting hole 522 and positioning hole 245.

[0067] Example 5:

[0068] Based on Example 1, 2, 3, or 4, see [link to example]. Figure 1 , 3 6. The lifting frame 200 also includes two track beams 260, which are horizontally mounted on guide columns 240 on both sides. The guide columns 240 have clearance notches 244 at their intersections with the track beams 260. A lifting trolley 300 is mounted on the track beams 260. By setting the track beams 260 and mounting the lifting trolley 300 on them, the tower section 1 on the ground can be lifted.

[0069] Specifically, the lifting trolley 300 can adopt the lifting trolley structure of a bridge crane. When lifting tower section 1, see... Figure 1 and Figure 10 Tower section 1 passes through the second channel 121 and is thus hoisted above the rotating platform 100. Then, the trolley 300 moves to the side of the first channel 111, aligning tower section 1 with the top of the tower.

[0070] See Figure 6 By setting the clearance gap 244, the movement of the lifting trolley 300 on the track beam 260 can be ensured without affecting it. Furthermore, the track beam 260 will not interfere with the lifting assembly 500, allowing the lifting assembly 500 to move up and down along the guide column 240 to adjust its position.

[0071] Specifically, see Figure 6The guide column 240 includes a lower column 241, an upper column 242, and a connector 243. The upper column 242 is installed above the lower column 241 at intervals through the connector 243. The two sides of the connector 243 are respectively provided with grooves, which form clearance notches 244. The track beam 260 is installed in the groove of the connector 243.

[0072] Of course, in order to prevent the balance beam 510 from interfering when the lifting trolley 300 lifts the tower section 1 toward the first channel 111, the balance beam 510 can be unloaded by the lifting trolley 300 first, and then reinstalled after the tower section 1 is installed with the tower.

[0073] The method of use or principle of this utility model:

[0074] See Figure 1 The rotating platform 100 is mounted on the tower via the first channel 111, and the lower end of the tower is fixed to the ground concrete foundation. A locking mechanism 600 is installed on the lower side of the rotating platform 100 located in the first channel 111.

[0075] Before the lifting operation, the tower section 1 is lifted by the trolley 300 and passed through the second channel 121, thus being lifted to the top of the rotating platform 100. Then, the trolley 300 moves to the side of the first channel 111, aligns the tower section 1 with the top of the tower, and then the tower section 1 is bolted to the tower.

[0076] Subsequently, the piston rods of the two lifting cylinders 520 extend downwards simultaneously, and the balance beam 510 abuts against the top of the tower. At this point, the locking mechanism 600 is released from its lock on the tower. As the piston rods of the lifting cylinders 520 extend further, the reaction force lifts the rotating platform 100 and the lifting frame 200. After one stroke of lifting, the locking mechanism 600 is locked back into place on the tower.

[0077] Afterwards, the pin 430 connecting the lifting cylinder 520 and the guide post 240 is removed, the piston rod of the lifting cylinder 520 retracts, the cylinder body of the lifting cylinder 520 moves along the lower side of the guide post 240, and then the lifting cylinder 520 is fixed to the guide post 240 by the pin 430 to carry out the next stroke of lifting.
