The outer sliding sleeve of the fixing rod 1 is provided with a sleeve 2, the sleeve 2 is used for fixing the antenna 3, and the sleeve 2 is connected with traction. The mechanism, the traction mechanism can drive the sleeve 2 to slide along the length of the pole.

In the antenna mounting assembly provided by the embodiment of the present application, since the sleeve 2 is sleeved outside the fixing rod 1 and the casing 2 is connected with the traction mechanism, when the antenna 3 is installed, the casing 2 only needs to be lowered to the installation. The person stands on the ground operable height, fixes the antenna 3 on the sleeve 2, and then pulls the sleeve 2 up by the traction mechanism to make the antenna 3 reach the required installation height. Similarly, when repairing and replacing the antenna 3 Simply operate the traction mechanism to lower the casing 2. The whole operation is completed by the traction mechanism, and the installation personnel do not need to climb the work, so there is no need to construct safety measures such as scaffolding, thereby reducing the safety risk and installation cost.

The traction mechanism may be as shown in FIG. 3, including a winch 4, a traction rope 5, and a fixed pulley 6. The fixed pulley 6 is fixed to the upper end of the fixed rod 1, and the first end of the traction rope 5 is wound on the winch 4, and the second end The fixed pulley 6 is bypassed and connected to the sleeve 2. Therefore, after the antenna 3 is fixed on the sleeve 2, only the winch 4 is rotated, and the traction rope 5 is gradually wound onto the winch 4, so that the second end of the traction rope 5 pulls the sleeve 2 upward in the axial direction. To realize the rise of the antenna 3, this operation can be completed by only one installer, which can save labor cost, and since the sleeve 2 is connected to the traction rope 5, the sleeve 2 can have a certain degree of rotational freedom, that is, the sleeve The tube 2 can be rotated by an angle about its own axis, so that when the antenna 3 is mounted on the sleeve 2, the sleeve 2 can be turned toward the outside of the building body to the inside of the building body, for example, can be rotated by 90°, so that the installer can be installed. The antenna 3 is mounted on the inside of the stairs, and the operation of the roof edge is not required to operate, thereby reducing the safety risk.

In order to prevent the casing 2 from wearing the traction rope 5 when moving in the axial direction, the fixing rod 1 can be arranged as a hollow tube structure. As shown in FIG. 3, a through hole penetrating the upper and lower ends of the fixing rod 1 can be opened inside the fixing rod 1. 11. A section of the traction rope 5 connected between the winch 4 and the fixed pulley 6 is disposed in the through hole 11, whereby the sleeve 2 does not come into contact with the traction rope 5 when moving in the axial direction, thereby effectively preventing The traction rope 5 is worn, which increases the service life of the traction rope 5.

Wherein, the traction rope 5 can be a steel wire rope or a nylon rope, etc., and the appropriate traction rope 5 material can be selected according to the weight of the actual antenna 3.

In order to make the antenna 3 and the sleeve 2 move smoothly in the axial direction, the two traction ropes 5 can be pulled. As shown in FIG. 3, the traction rope 5 includes a first traction rope 51 and a second traction rope 52. The fixed pulley 6 includes a first fixed pulley 61 and a second fixed pulley 62, and the first traction rope 51 and the second traction rope 52 The first end is wound on the winch 4, the second end of the first traction rope 51 bypasses the first fixed pulley 61 and is connected with the first side of the sleeve 2, and the second end of the second traction rope 52 bypasses the second end The pulley 62 is coupled to the second side of the sleeve 2, the first side of the sleeve 2 being axially symmetrical with respect to the axis of the sleeve 2 with the second side of the sleeve 2. Thereby, the traction forces received on both sides of the sleeve 2 can be symmetrically distributed, and when the sleeve 2 is lifted in the axial direction, the uniform traction force can prevent the sleeve 2 from being stuck due to the skew.

Correspondingly, as shown in FIG. 3, the first fixed pulley 61 and the first side of the sleeve 2 may be disposed in the same vertical direction, and the second fixed pulley 62 and the second side of the sleeve 2 may be disposed in the same In the vertical direction. Thereby, the length of the traction rope 5 between the fixed pulley 6 and the sleeve 2 can be kept vertical, and the traction rope 5 can be prevented from coming off the fixed pulley 6 due to the skew. Moreover, the direction of the traction force received by the sleeve 2 can be ensured to be vertically upward, so that the pulling force is labor-saving.

When the traction mechanism pulls the antenna 3 to a predetermined mounting position, it is necessary to fix the sleeve 2 relative to the fixed rod 1 to maintain the antenna 3 in the mounted position. At this time, the winch 4 can be locked, for example, the self-locking winch 4 can be used to lock the winch 4 to the rotation in the direction in which the sleeve 2 is lowered, so that the traction rope 5 cannot be released by the winch 4, and the antenna 3 is kept at The installation location. And the self-locking winch 4 can also prevent the installer from accidentally loosening the sleeve 2 and the antenna 3 to fall and damage.

In addition, a locking mechanism can also be connected to the sleeve 2, and the sleeve 2 can be locked and fixed relative to the fixing rod 1 by the locking mechanism.

When it is necessary to lower the antenna 3, the nut 8 can be unscrewed and the bolt 7 can be pulled out to release the lock. This structure is simple and easy to operate.

In order to reserve sufficient operating space, the opening positions of the first locking hole 21 and the second locking hole 12 can be shifted from the mounting side of the antenna 3, that is, the position of the first locking hole 21 is located on the mounting side of the antenna 3. In the different circumferential directions, there is sufficient operating space for operating the bolt 7 and the nut 8.

As shown in FIG. 4, the first locking hole 21 and the second locking hole 12 can be opened one at a time. In this case, the opening positions of the first locking hole 21 and the second locking hole 12 need to be calculated in advance. When the sleeve 2 is caused to raise the antenna 3 to a predetermined mounting height, the first locking hole 21 and the second locking hole 12 can be correspondingly connected.

In addition, as shown in FIG. 5, the first locking hole 21 may be plural, and the plurality of first locking holes 21 are arranged along the axial direction of the sleeve 2. At this time, the second locking hole 12 may be combined with any one. The first locking hole 21 is correspondingly connected. When the second locking hole 12 is correspondingly communicated with the different first locking hole 21, the height of the sleeve 2 is also different, thereby the sleeve 2 can be fixed relative to the fixing rod. 1 Fixed at a plurality of different height positions, the installation position of the antenna 3 can be changed up and down according to actual needs, to adapt to various application scenarios, and the versatility of the antenna installation component is improved.
