[0002] Base station AAU equipment (Active Antenna Unit) is a wireless communication device used in mobile communication base stations. It integrates antennas, radio frequency modules and digital processing units to send and receive wireless signals. AAU equipment is usually installed on base station towers or buildings to provide mobile communication network coverage and capacity support.

[0003] The installation of existing base station AAU equipment is usually carried out by hoisting. However, the hoisting rope is unstable and is easily affected by various factors (such as high-altitude crosswinds) during hoisting, causing shaking, and then colliding with the base station bracket, causing damage to the AAU equipment. For this reason, when hoisting the AAU equipment, it is usually necessary to connect an additional guide rope to the AAU equipment, and the staff at the bottom pull it outward to avoid the collision between the AAU equipment and the base station bracket. However, due to the installation location of the communication base station, when installing the AAU equipment on a relatively narrow mountaintop communication base station, it is inconvenient for the staff at the bottom to pull it outward, resulting in inconvenience in the hoisting process of the AAU equipment, and there is a possibility of damage to the AAU equipment and the communication base station bracket.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figures 1 to 5 As shown, an embodiment of the utility model provides an auxiliary installation device for an AAU of a communication base station, comprising a base 1, an inner wall of the base 1 being slidably connected with an auxiliary frame 4 for placing an AAU device, the AAU device can be placed in the auxiliary frame 4 after debugging, a traction rope 11 and an auxiliary rope 41 are fixedly connected to the top of the base 1 and the auxiliary frame 4 respectively, the traction rope 11 is used to pull the entire base 1 together with the auxiliary frame 4 to rise, and the auxiliary rope 41 is only used to pull the auxiliary frame 4 to rise, a positioning component for positioning the auxiliary frame 4 is arranged on the top of the base 1, and a supporting component for separating the AAU device from the communication base station bracket by a certain distance is installed on the surface of the base 1.

[0023] Specifically, the AAU device is installed in the auxiliary frame 4, and the entire device is set on the base station bracket through the supporting assembly. By lifting the traction rope 11, the base 1 can be pulled to drive the entire device to move up. When the installation height is reached, the auxiliary frame 4 can be driven to lift the AAU device separately by lifting the auxiliary rope 41, thereby avoiding obstacles to the installation caused by the base 1 and the supporting assembly.

[0024] like Figure 4 and Figure 5 As shown, in this embodiment, the support assembly includes a support frame A2 fixedly connected to the surface of the base 1, one end of the support frame A2 is fixedly connected to a guide rail 21, and sliding plates 22 are slidably connected near both ends of the guide rail 21. By adjusting the lateral position of the sliding plate 22 in the guide rail 21, base station steel pipe towers of different sizes can be adapted, and a contact assembly for adapting to the base station bracket is installed on the surface of the sliding plate 22.

[0025] In a parallel embodiment, the support assembly includes a support frame B3 fixedly connected to the surface of the base 1, one end of the support frame B3 is fixedly connected to a connecting frame 31, one side of the connecting frame 31 is rotatably connected to a positioning wheel 32, a movable groove is opened on the surface of the connecting frame 31, and a movable block 331 is slidably connected through the movable groove, and one side of the movable block 331 is rotatably connected to a movable wheel 33.

[0026] Specifically, the positioning wheel 32 and the movable wheel 33 are both grooved rollers, and are arc-shaped grooved rollers, which are convenient for adapting to the single-tube tower of the base station. The positioning wheel 32 and the movable wheel 33 are clamped together on the single-tube tower to locate the position of the base 1.

[0027] The contact assembly includes a positioning rod 23 fixedly connected to one end of the sliding plate 22 , a sliding block 231 is slidably connected to the surface of the positioning rod 23 , and a pulley 233 is rotatably connected to the surface of the sliding block 231 .

[0028] Specifically, by setting a slider 231 that slides on the positioning rod 23, when the pulley 233 is clamped on the steel pipe tower, since most steel pipe towers are wide at the bottom and narrow at the top, a slider 231 that can slide and adjust its position is set to facilitate adaptation to the narrowing shape of the steel pipe tower during the continuous upward movement process. The pulley 233 is a groove pulley and is clamped on the bracket of the steel pipe tower. It can drive the slider 231 to adjust its position on the positioning rod 23 in time according to the upward movement state to avoid the pulley 233 from being separated from the steel pipe bracket.

[0029] Furthermore, in this embodiment, the slider 231 is connected to the sliding plate 22 through a tension spring 232, and the two ends of the tension spring 232 are fixedly connected to the slider 231 and the sliding plate 22 respectively. Under the action of the tension spring 232, a force is given to the slider 231 to always move toward the sliding plate 22, thereby helping the slider 231 to adapt to the steel pipe tower that gradually narrows when moving upward.

[0030] Furthermore, in the present embodiment, a plurality of screw holes 221 are provided on the surface of the sliding plate 22, two fixing bolts 222 are threadedly connected to the surface of the guide rail 21, and the fixing bolts 222 are passed through the screw holes 221. By selecting a suitable screw hole 221, the fixing bolts 222 are inserted inwardly and tightened on the surface of the guide rail 21, thereby fixing the position of the sliding plate 22 and adapting to steel pipe towers of different widths.

[0031] like Figure 5 As shown, in this embodiment, a screw rod 332 is rotatably connected in the movable groove, and the screw rod 332 is threadedly connected to the movable block 331. By rotating the screw rod 332, the movable block 331 in the movable groove can be driven to move forward and backward, thereby adjusting the relative distance between the movable wheel 33 and the positioning wheel 32, so that the movable wheel 33 and the positioning wheel 32 can be clamped on the single-tube support column of the single-tube support tower.

[0032] like Figure 2 and Figure 3 As shown, in the present embodiment, the positioning assembly includes two fixed blocks 43 fixedly connected to the top of the base 1, a pull rod 431 is passed through the fixed block 43, one end of the pull rod 431 is fixedly connected to a clamping block 432, the lower end surface of the clamping block 432 is set as an arc surface, the clamping block 432 is connected to the fixed block 43 through a spring 433, and the two ends of the spring 433 are respectively fixedly connected to the clamping block 432 and the fixed block 43, and the auxiliary frame 4 is provided with a rack 42 adapted to the clamping block 432 on one side close to the fixed block 43. Under normal conditions, the clamping block 432 is stuck in the rack 42, and because the lower end of the clamping block 432 is set as an arc surface, the clamping block 432 and the rack 42 form a ratchet structure, so the rack 42 can only move upward, and when the rack 42 needs to move downward, it will be blocked by the upper end plane of the clamping block 432 and cannot move downward. Therefore, through the setting of the clamping block 432, it is convenient to position and support the lifting auxiliary frame 4.

[0033] Working principle:

[0034] When the AAU equipment needs to be hoisted, the debugged AAU equipment is placed in the auxiliary frame 4, and then the support assembly is aligned and connected with the base station support tower on the ground. If it is a steel pipe frame, the sliding plate 22 is adjusted to slide in the guide rail 21 and fastened by the fixing bolt 222. When the pulley 233 is clamped on the bottom surface of the steel pipe frame, the slider 231 is first pulled outward on the positioning rod 23, and the tension spring 232 is stretched to leave redundancy for the gradual narrowing of the upper end of the steel pipe frame. If it is a single single-tube tower frame, the device is clamped on the single-tube tower frame by the cooperation of the positioning wheel 32 and the movable wheel 33. At the same time, Support frame A2 or support frame B3 is used to separate the AAU equipment from the base station bracket by a certain distance. At this time, the AAU equipment can be driven to move up by lifting the traction rope 11. After moving up to a position close to the installation position, the traction rope 11 is fixed and the auxiliary rope 41 is continued to be pulled to make the auxiliary frame 4 drive the AAU equipment to move up. During this process, the block 432 cooperates with the rack 42 to enable the auxiliary frame 4 to move up. After the auxiliary frame 4 stops moving up, the block 432 pushed by the spring 433 is stuck on the surface of the rack 42, thereby fixing the auxiliary frame 4. At this time, the AAU equipment can be conveniently taken out or installed.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
