[0041] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0042] Example 1:

[0043] See Figures 1-4 As shown, Embodiment 1 of this application provides a wall-mounting device for a single-limb inclined steel tower crane, which includes a first wall-mounting mechanism 1 and a second wall-mounting mechanism 3. One end of the first wall-mounting mechanism 1 is used to connect to the tower crane 2. The second wall-mounting mechanism 3 includes a connecting rod 34 arranged along the transverse bridge direction and two second wall-mounting components 30 respectively disposed on both sides of the connecting rod 34. The length of the connecting rod 34 is greater than the cross-sectional length of the single-limb inclined steel tower 4, and the connecting rod 34 is connected to the first wall-mounting mechanism 1. A receiving space for accommodating the single-limb inclined steel tower 4 is formed between the two second wall-mounting components 30, and the second wall-mounting component 30 includes a support rod 300 and a first support leg 301. The support rod 300 is arranged along the longitudinal bridge direction, and one end of the support rod 300 is connected to the connecting rod 34. One end of the first support leg 301 is perpendicularly connected to the other end of the support rod 300, and the other end is used to connect to the single-limb inclined steel tower 4.

[0044] The wall-attached device of the general tower crane connects the tower crane with the single-limb steel tower to form a triangular structure, but due to the small cross section of the single-limb inclined steel tower, the length of the side of the triangular structure is long, and the triangular structure formed by the tower crane, the wall-attached device and the single-limb steel tower is not stable, and does not meet the painting construction of the single-limb inclined steel tower with a small cross section.

[0045] The wall-attached device of the embodiment 1 of the present application increases the cross section of the single-limb inclined steel tower 4 through the two first support legs 301, increases the local strength of the single-limb inclined steel tower 4, forms a stable quadrilateral structure with the first support leg 301 through the setting of the connecting rod 34 and the support rod 300, improves the stability of the single-limb inclined steel tower 4, and finally connects the tower crane 2 through the first wall-attached mechanism 1, so that it is possible to set the tower crane 2 on the single-limb inclined steel tower 4 with a high height and a small cross section, the painting and the auxiliary structure construction of the single-limb inclined steel tower 4 are carried out through the setting of the tower crane 2, the use of large hoisting equipment and aerial work vehicles is reduced, the installation and removal of the wall-attached device can be completed by the tower crane 2 itself, and other cranes are not needed, so that the construction cost is effectively reduced and the construction period is shortened.

[0046] Optionally, referring to Figure 1 , the second wall-attached mechanism 3 further includes an inclined rod 31, one end of the inclined rod 31 is connected with the support rod 300, and the other end extends obliquely upward to be connected with the single-limb inclined steel tower 4.

[0047] The inclined rod 31 is arranged to form a stable triangular structure between the inclined rod 31, the support rod 300 and the side wall of the single-limb inclined steel tower 4, and to improve the local stability of the single-limb inclined steel tower 4.

[0048] Preferably, the inclined rod 31 is connected to the middle part of the support rod 300.

[0049] The inclined rod 31 is connected to the middle part of the support rod 300, which not only enhances the strength of the single-limb inclined steel tower 4, but also increases the strength of the support rod 300.

[0050] Further, referring to Figure 2 and Figure 3 , the second wall-attached mechanism 3 further includes a plurality of reinforcing rods 32, and the reinforcing rods 32 are connected between the two support rods 300.

[0051] Since the length of the support rod 300 is long, the reinforcing rod 32 is arranged to improve the stability of the support rod 300.

[0052] Further, referring to Figure 3 and Figure 5As shown, the second wall-attached mechanism 3 further comprises a second support leg 33, which is located between the two support rods 300 and has one end connected with the single-limb inclined steel tower 4 and the other end connected with the reinforcing rod 32.

[0053] Since the single-limb inclined steel tower 4 has a high height and a small cross section, the stability of the single-limb inclined steel tower 4 is insufficient when connected with the two first support legs 301 on both sides of the single-limb inclined steel tower 4. The second support leg 33 is further connected with the single-limb inclined steel tower 4 on the side close to the tower crane 2, thereby further increasing the stability of the connection between the wall-attached device and the single-limb inclined steel tower 4.

[0054] Further, referring to Figure 3 As shown, the first wall-attached mechanism 1 comprises a wall-attached frame 10 and a wall-attached rod 11. The wall-attached frame 10 is used to be sleeved on the tower crane 2. The wall-attached rod 11 has two ends respectively connected with the wall-attached frame 10 and the second wall-attached mechanism 3.

[0055] The wall-attached frame 10 is adapted to the cross section of the tower crane 2 and is fixed on the tower crane 2. The wall-attached rod 11 is connected with the second wall-attached mechanism 3, thereby preventing the damage of the tower crane 2.

[0056] Further, referring to Figure 3 and Figure 6 As shown, the wall-attached rod 11 is provided with three rods. Two of the wall-attached rods 11 have one end connected with the end of the support rod 300 and the other end connected with the corner of the wall-attached frame 10 on the same side of the support rod 300. The remaining wall-attached rod 11 has one end connected with the end of the support rod 300 and the other end connected with the corner of the wall-attached frame 10 on the opposite side of the support rod 300.

[0057] In the embodiment 1, two of the wall-attached rods 11 have one end connected with the end of the support rod 300 and the other end connected with the corner of the wall-attached frame 10 on the same side of the support rod 300, thereby realizing the connection between the wall-attached frame 10 and the two support rods 300. The remaining wall-attached rod 11 has one end connected with the end of the support rod 300 and the other end connected with the corner of the wall-attached frame 10 on the opposite side of the support rod 300, thereby realizing the connection between the wall-attached frame 10 and the connecting rod 34 and enhancing the connection strength between the wall-attached frame 10 and the second wall-attached mechanism 3.

[0058] Further, referring to Figure 7 and Figure 8 As shown, the corner of the wall-attached frame 10 is provided with a through hole penetrating through the wall-attached frame 10. The wall-attached rod 11 comprises a rod body 110, a clamping groove 111 and a pin shaft 112. One end of the rod body 110 is connected with the support rod 300. The clamping groove 111 is connected with the other end of the rod body 110. The wall-attached frame 10 is located in the clamping groove 111. The clamping groove 111 is provided with a mounting hole. The wall-attached frame 10 is connected with the clamping groove 111 through the pin shaft 112. The pin shaft 112 penetrates through the mounting hole and the through hole.

[0059] Through the connection of the pin shaft 112, detachable connection of the wall-attached rod 11 and the wall-attached frame 10 is realized, and the angle of the wall-attached rod 11 can be adjusted to form a stable connection structure.
