[0002] A signal tower is a wireless signal transmitting device built by network operators such as China Mobile, China Unicom, and China Telecom. It is called a signal tower because of its tower-like appearance. It is also a form of public radio station, which refers to a radio transceiver station that transmits information between mobile phone terminals through a communication exchange center in a certain radio coverage area.

[0003] When installing a signal tower, a pit is usually dug first, and then a circular structure composed of multiple steel bars is set in the pit, and then concrete is poured in the pit. Then the base of the signal tower is connected to the steel bars and installed on the base poured with concrete. The existing signal tower base and steel bars are connected by a crane to lift the signal tower and the base above the steel bars, and then multiple workers stabilize the signal tower and the base and connect them with the steel bars. However, when the crane moves the signal tower and the base to the steel bars, the signal tower and the base will shake, and the shaking signal tower and base may hit the workers, causing injuries to the workers. After the signal tower is connected to the steel bars, the workers need to rotate multiple nut blocks and cooperate with the steel bars to install the signal tower on the concrete base. This is time-consuming and labor-intensive, and reduces the installation efficiency of the signal tower. Therefore, an adjustable base for a communication signal tower is proposed to solve the above problems. Utility Model Content

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1-6 , an adjustable base for a communication signal tower, comprising embedded steel bars 2, a plurality of embedded steel bars 2 are provided and embedded in the base, the top portion of the embedded steel bars 2 extends out of the ground and is provided with threads (the threads are for facilitating the installation of nut blocks 9), a base body 1 cast by concrete is provided around the embedded steel bars 2, the base body 1 is located above the ground, a guide assembly is provided at the top of the base body 1 (the guide assembly can align the docking port on the signal tower base 8 with the embedded steel bars 2, so as to facilitate the installation of the signal tower body 3 on the base body 1), the guide assembly comprises a plurality of trapezoidal guide blocks 4 fixedly connected to the top of the base body 1 (the trapezoidal guide blocks 4 are arranged in a circular manner, so that the signal tower base 8 can be docked with the embedded steel bars 2), and each trapezoidal guide block 4 corresponds to the embedded steel bars 2;

[0023] A signal tower body 3 is arranged above the base body 1 , and a signal tower base 8 is fixedly connected to the bottom end of the signal tower body 3 . A plurality of docking ports that fit with the embedded steel bars 2 are provided at the bottom end of the signal tower base 8 .

[0024] Furthermore, the signal tower body 3 is connected to the base body 1 through a connecting assembly, which includes a movable groove opened at one end of a trapezoidal guide block 4, a rotating ring 6 is arranged in the movable groove, and teeth are fixedly connected to the inner surface of the rotating ring 6 (the rotating ring 6 and the teeth rotate and drive the gear ring 10 and the nut block 9 to rotate and move downward, thereby fastening the signal tower base 8 and the base body 1), and the surface of the signal tower body 3 is provided with relatively arranged arc disks 5 (two arc disks 5 are provided so that the arc disks 5 can be disassembled), and the surface of each arc disk 5 is fixedly connected with relatively arranged pushing blocks 7 (the pushing block 7 pushes the rotating ring 6, so that the rotating ring 6 and the nut block 9 move downward synchronously).

[0025] It should be noted that: the top of the arc disk 5 is provided with an insertion interface that matches the embedded steel bar 2, the bottom end of the arc disk 5 is rotatably connected to a nut block 9 threadedly connected to the embedded steel bar 2, and the surface of the nut block 9 is fixedly connected to a gear ring 10 that meshes with the teeth, wherein the two nut blocks 9 and the gear ring 10 are divided into two.

[0026] It is worth noting that a circular groove is formed at the bottom end of the rotating ring 6, a connecting ring 11 is rotatably connected in the circular groove, and a spring is fixedly connected between the bottom end of the connecting ring 11 and a side surface of the movable groove.

[0027] A further advantage of adopting the above method is that the above device can achieve the docking of the signal tower base 8 and the base body 1 without the staff holding the signal tower body 3 and the signal tower base 8, thereby avoiding the signal tower body 3 shaking and hitting the staff, causing injury to the staff; at the same time, there is no need for the staff to rotate multiple nut blocks 9, which saves time and effort while improving the installation efficiency of the signal tower body 3.

[0028] The utility model is used in the following manner: when a communication signal tower needs to be installed, the staff first buries a circular structure composed of a plurality of embedded steel bars 2 in a pre-dug pit, then pours concrete in the pit, and uses concrete to pour a circular base body 1 around the embedded steel bars 2 that extend beyond the ground, and then a plurality of trapezoidal guide blocks 4 corresponding to the embedded steel bars 2 are arranged on the top of the base body 1, and then the staff uses a crane to lift the signal tower body 3 and the signal tower base 8, and lift them above the base body 1;

[0029] Then the staff controls the crane to slowly move the signal tower body 3 and the signal tower base 8 downward. When the signal tower base 8 contacts the inclined surface of the trapezoidal guide block 4, the staff continues to control the signal tower body 3 and the signal tower base 8 to move downward. Due to the effect of the inclined surface of the trapezoidal guide block 4, the signal tower body 3 and the signal tower base 8 will slowly move to the middle of the base body 1 and move to the docking interface on the signal tower base 8 to align with the embedded steel bars 2. Then the signal tower base 8 is moved downward by the crane until it contacts the top of the base body 1.

[0030] Then the staff puts the two arc disks 5 on the surface of the signal tower body 3, and moves the two arc disks 5 downward, so that the nut block 9 at the bottom of the arc disk 5 is put on the surface of the embedded steel bar 2, and at the same time, the toothed ring 10 on the surface of the nut block 9 is meshed with the teeth. At this time, the pushing block 7 contacts the top of the rotating ring 6, and then the staff rotates the rotating ring 6. The rotating ring 6 rotates to drive the teeth to rotate, and the rotation of the teeth drives the multiple toothed rings 10 meshed with them to rotate. The rotation of the toothed ring 10 drives the nut block 9 to rotate, so that the nut block 9 moves downward along the surface of the embedded steel bar 2. The downward movement of the nut block 9 drives the arc disk 5 downward. The downward movement of the arc disk 5 drives the rotating ring 6 and the nut block 9 to move downward synchronously through the pushing block 7. The nut block 9 is rotated to contact the top of the signal tower base 8 by rotating the rotating ring 6.

[0031] Then the staff can use the crane to splice and install the remaining signal tower bodies 3. The above device can achieve the docking of the signal tower base 8 and the base body 1 without the staff holding the signal tower body 3 and the signal tower base 8, thereby avoiding the signal tower body 3 shaking and hitting the staff, causing injuries to the staff; at the same time, there is no need for the staff to rotate multiple nut blocks 9, which saves time and effort while improving the installation efficiency of the signal tower body 3.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
