An antenna panel combination adjustment device

technical field

The utility model relates to the field of antenna assembly, in particular to an antenna panel combination adjustment device used between panels and panel supports in medium and large antennas that require precise positioning of the panels.

Background technique

Antennas play a huge role in satellite communications. The needs of technological development put forward higher requirements for the root mean square accuracy of the antenna profile. The structure of the modern antenna reflector is that the reflective panels are continuously laid on the panel supports interconnected into a grid. However, due to errors in processing and installation, the relative positions of the panel and the support often need to be adjusted within a small range according to specific needs.

The traditional adjustment method, especially for medium-sized or large-scale antennas, requires workers to climb and drill in the grid of the support under the panel, and each adjustment unit needs to be loosened-adjusted-tightened. series of steps to achieve. The disadvantage of this is that the efficiency is very low, and the personal safety of workers is also difficult to guarantee.

Utility model content

The purpose of the utility model is to provide an antenna panel combination adjustment device with simple structure, which can safely and easily complete the precision adjustment operation of the reflector.

In order to accomplish the above object, the technical solution adopted by the utility model is:

An antenna panel combination adjustment device, including a base fixed at one end on the antenna support body, a vertical through screw hole is provided at the position corresponding to the base and the antenna panel, and a screw hole fixed on the Z-shaped rib of the antenna panel Positioning device, the positioning device is arranged at the bend of the upper end of the Z-shaped rib, and the center of the positioning device is provided with a vertical through hole; the base and the positioning device are connected by bolts, and the bolts are assembled in the through holes of the positioning device and the screw holes in the base.

The positioning device includes a positioning block and a clamping block fixed together, a through hole with a ring-shaped clamping groove is provided in the center of the junction of the positioning block and the clamping block, and the positioning block and the clamping block are fixed on the antenna panel by fastening bolts The vertical plate of the Z-shaped rib.

The bolts are hexagon socket bolts, and the bolts are provided with annular protrusions at the positions of the annular slots in the through holes of the positioning device.

The beneficial effects of the utility model are: adopting the special-shaped inner hexagonal bolt with annular protrusion and the positioning device with the ring-shaped slot matched with it, screw holes are set on the base, and the thread of the special-shaped inner hexagonal bolt is consistent with the screw hole of the base. Cooperate, so that the worker can complete the adjustment of the antenna above the antenna panel through a simple rotation action using a hexagonal wrench, which eliminates the disadvantages of workers working under the panel.

Detailed ways

The utility model relates to an antenna panel combination adjustment device, which adopts a positioning device with an inner hexagonal bolt with a ring-shaped protrusion and a ring-shaped slot matched with it, and sets screw holes on the base. The holes match each other, so that workers can complete the adjustment of the antenna above the antenna panel by simply rotating the hexagonal wrench, which eliminates the disadvantages of workers working under the panel.

Below in conjunction with accompanying drawing, the utility model is further described:

Specific embodiment, as shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, a kind of antenna panel combination adjustment device, comprises the base 1 that one end is fixedly connected on the antenna support body, the position corresponding to base 1 and antenna panel is set There is a vertically through screw hole; it also includes a positioning device fixed on the Z-shaped rib 6 of the antenna panel, the positioning device is arranged at the corner bend at the upper end of the Z-shaped rib 6, and the positioning device includes a positioning block buckled together 3 and block 4, the center of the junction of positioning block 3 and block 4 is provided with a through hole with an annular slot, and a hexagon socket bolt 2 is assembled in the through hole, and the upper end of the hexagon socket bolt 2 passes through the raised annular surface and The annular grooves of the positioning block 3 and the clamping block 4 are matched for positioning, and the lower end is connected with the screw hole of the base 1. The positioning block 3 and the clamping block 4 are interlocked and fixed to the vertical plate of the Z-shaped rib 6 of the antenna panel by the fastening bolt 5 superior.

When the utility model is in use, the base 1 is first fixed on the antenna support body, and the hexagon socket bolt 2 is assembled in the through hole formed at the joint where the positioning block 3 and the clamping block 4 are fastened together. The hexagon socket bolt 2 The ring-shaped projections of the rings cooperate with the ring-shaped slots in the through holes, and then the positioning block 3 and the block block 4 are fixed on the vertical plate of the Z-shaped rib 6 of the antenna panel with the fastening bolt 5, and the hexagon socket head bolt is rotated with a hexagonal wrench 2. Connect the threaded end of the hexagon socket bolt 2 with the screw hole of the base 1. The hexagon socket bolt 2 can rotate in the axial direction relative to the antenna panel without horizontal relative displacement. Through the screw connection, the hexagon socket bolt 2 The axial rotation movement causes an axial displacement of the antenna panel relative to the antenna support body, thereby realizing adjustment and fixation of the antenna panel. The hexagon socket bolts with ring-shaped protrusions and the positioning device with ring-shaped slots are used to set screw holes on the base. The threads of the hexagon socket bolts match the screw holes of the base, so that workers can only use a hexagon wrench to pass through. The adjustment of the antenna can be completed above the antenna panel with a simple rotation action, which eliminates the disadvantages of workers working under the panel.
