[0062] In one embodiment of the present invention, the tower crane 1 includes a plurality of connecting frames 3, each of which is provided with four connecting pipes 4 at the upper and lower ends. In every two adjacent connecting frames 3, the four connecting pipes 4 in one connecting frame 3 are respectively connected to the four pipes of the other connecting frame 3 through a stabilizing device ( Figure 2 Only one connecting pipe 4 in one of the connecting racks 3 located above and another connecting pipe in another connecting rack 3 are shown, and the two connecting pipes are aligned and can be installed with each other), wherein the stabilizing device includes:

[0063] The first activity mechanism, the second activity mechanism and the third activity mechanism, wherein:

[0064] The second movable mechanism is connected to the first movable mechanism and is used to buffer the movable force generated by the first movable mechanism;

[0065] The third movable mechanism is connected to the second movable mechanism and is used to buffer the movable force generated by the second movable mechanism.

[0066] The following is a detailed explanation.

[0067] In one embodiment of the present invention, the first movable mechanism includes two groups of first movable components 5, wherein the two groups of first movable components 5 are symmetrically distributed in one of the connecting pipes 4 at the lower end of one connecting frame 3 and one of the connecting pipes 4 at the lower end of the other connecting frame 3.

[0068] In this embodiment, the first movable component 5 includes a wall plate 51, a first arc rod 52, a first arc spring 53 and a first rotating rod 54, wherein:

[0069] The wall plate 51 is provided on the inner wall of one of the connecting pipes 4 at the lower end of one of the connecting frames 3;

[0070] One end of the first rotating rod 54 is hinged to one of the connecting pipes 4 at the lower end of the other connecting frame 3, and the first rotating rod 54 can rotate under the action of an external force;

[0071] One end of the first arc-shaped rod 52 is connected to the wall plate 51 , and the other end of the first arc-shaped rod 52 passes through a first through-hole 541 formed on the other end of the first rotating rod 54 ;

[0072] The first arc spring 53 is sleeved on the middle portion of the first arc rod 52 , wherein one end of the first arc spring 53 can contact the wall plate 51 , and the other end of the first arc spring 53 can contact the first rotating rod 54 .

[0073] Therefore, in this embodiment, the size of the first through hole 541 can be set as needed, and can be large or small, as long as the first arc rod 52 can be finally Figure 4 When the first arc rod 52 is rotated downward, the other end of the first arc rod 52 can move in the first through hole 541, and at the same time, the first arc spring 53 will not pass through the first through hole 541. Figure 2 When the upper connecting pipe 4 is slightly shaken to the right, the first arc rod 52 will move, and at the same time the first arc spring 53 on the first arc rod 52 will be compressed. When the first arc spring 53 is compressed, the first rotating rod 54 will be rotated (by force). Figure 4 From the perspective of FIG. 5 , the first arc-shaped rod 52 rotates clockwise).

[0074] In one embodiment of the present invention, the second movable mechanism includes a second movable assembly 6 , wherein two groups of second movable assemblies 6 are symmetrically distributed in one of the connecting pipes 4 at the lower end of the other connecting frame 3 .

[0075] In this embodiment, the second movable assembly 6 includes a supporting assembly 61, a first fixing rod 62, a second arc rod 63, a second arc spring 64, a connecting rod 65 and a third rotating rod 66, wherein:

[0076] The support assembly 61 includes a support rod 611 and two second rotating rods 612. One end of the support rod 611 is arranged on the fixed plate 41 in one of the connecting pipes 4 at the lower end of the other connecting frame 3. One end of the second rotating rod 612 is hinged to the other end of the support rod 611 (the second rotating rod 612 can rotate).

[0077] One end of the first fixing rod 62 is arranged on the inner wall of one of the connecting pipes 4 at the lower end of the other connecting frame 3;

[0078] One end of the third rotating rod 66 is hinged to the inner wall of one of the connecting pipes 4 at the lower end of the other connecting frame 3, and the third rotating rod 66 is located below the first fixed rod 62;

[0079] One end of the second curved rod 63 is connected to the other end of the first fixed rod 62. One end of the second curved rod 63 passes through the second through-hole 6121 defined at the other end of the second rotating rod 612. The other end of the second curved rod 63 passes through the third through-hole 661 defined at the other end of the third rotating rod 66.

[0080] The second arc spring 64 is sleeved on the second arc rod 63 , wherein one end of the second arc spring 64 can contact the second rotating rod 612 , and the other end of the second arc spring 64 can contact the third rotating rod 66 ;

[0081] One end of the connecting rod 65 is hinged to the other end of the first rotating rod 54, and the other end of the connecting rod 65 is hinged to the other end of the second rotating rod 612. When the first rotating rod 54 is rotated by force, the second rotating rod 612 will be driven to rotate (by the action of the connecting rod 65). Figure 4 , the second rotating rod 612 rotates counterclockwise when viewed from the direction of rotation.

[0082] In this embodiment, the size of the third through-hole 661 can be set as needed, and the shape of the middle portion of the second arc-shaped rod 63 is the same as the rotation trajectory of the second rotating rod 612 (that is, the second arc-shaped rod 63 has a section whose shape is the same as the rotation trajectory of the third rotating rod 66, so that the second rotating rod 612 can smoothly rotate on this section of the second arc-shaped rod 63). Therefore, when the second rotating rod 612 rotates, the second arc spring 64 can be compressed. When the second arc spring 64 is compressed, the third rotating rod 66 is forced to rotate (to Figure 4 , the third rotating rod 66 rotates clockwise).

[0083] In one embodiment of the present invention, the third movable mechanism includes two groups of third movable components 7 , wherein the two groups of third movable components 7 are symmetrically distributed in one of the connecting pipes 4 at the lower end of the other connecting frame 3 .

[0084] In this embodiment, the third movable assembly 7 includes a third arc rod 71, a third arc spring 72 and a second fixed rod 73, wherein:

[0085] One end of the second fixing rod 73 is provided on the inner wall of one of the connecting pipes 4 at the lower end of the other connecting frame 3 , and the second fixing rod 73 is located below the first fixing rod 62 ;

[0086] One end of the third curved rod 71 is connected to the other end of the fixed rod. The third curved rod 71 extends through a fourth through-hole 662 formed at the other end of the third rotating rod 66. The other end of the third curved rod 71 is connected to the fixed plate 41. One end of the third curved spring 72 can contact the third rotating rod 66, while the other end of the third curved spring 72 can contact the fixed plate 41. (The portion of the fixed plate 41 that contacts the other end of the third curved spring 72 is made of an elastic material, such as rubber.)

[0087] In this embodiment, the size of the fourth through-hole 662 can be set as needed, and the shape of the middle portion of the third curved rod 71 is the same as the rotation trajectory of the third rotating rod 66 (that is, the third curved rod 71 has a section whose shape is the same as the rotation trajectory of the third rotating rod 66, so that the third rotating rod 66 can smoothly rotate along this section of the third curved rod 71). When the third rotating rod 66 rotates, it compresses the third curved spring 72. When the third curved spring 72 is compressed, the compressive force of the third curved spring 72 is vertically transmitted to the fixed plate 41. By vertically transmitting the compressive force of the third curved spring 72 to the fixed plate 41, it also avoids affecting the Figure 2 The connecting pipe 4 below avoids Figure 2 The connecting pipe 4 below shakes left and right. At the same time, due to the action of the three springs (the first arc spring, the second arc spring and the third arc spring) (the spring has a reaction force), it can avoid Figure 2 The upper connecting pipe 4 has an excessively large swing amplitude, which ultimately improves the stability of the entire tower crane 1.

Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with this profession can make some changes or modifications to equivalent embodiments of the technical contents disclosed above without departing from the scope of the technical solution of the present invention.
