Detailed Description
This is described in detail below with reference to fig. 1-10.
Example 1
The antenna tower in the prior art is mainly found to have the following defects through long-time practical application:
(1) the existing antenna tower is mostly of an integral structure and is inconvenient to install, transport and hoist;
(2) the rotator is installed in a single mode, and is generally only suitable for top installation of the rotator;
(3) a rotator that is only suitable for a certain size;
(4) the azimuth zero point adjustment and the large disc horizontal adjustment are inconvenient;
(5) the height is fixed, and the height can not be flexibly changed by matching with a standard component.
Therefore, the embodiment discloses a satellite antenna support tower based on a self-locking structural part. The support tower comprises at least three tower sections. For example, as shown in fig. 1 and 2, the support tower includes a first tower section 100, a second tower section 200, and a third tower section 300. It may also comprise a fourth tower section connected to the third tower section 300, etc., if it has higher requirements in axial height. The first, second and third pylon segments 100, 200, 300 are each connected via a connecting element. According to different connection requirements, the connecting parts can be bolts with different specifications. Each pylon segment needs to have a high degree of levelness after connection, at least three pylon segments having substantially the same angle of inclination a, as shown in fig. 1. The angle of inclination alpha has a design value alpha at design time0. And after the tower sections have been mounted in sequence, the angle of inclination a approaches the design value a0So as to ensure that the installation requirements are met after the installation of the azimuth motor and the pitching motor.
The first tower section 100 includes at least three diagonal braces 100a and at least two mounting plates 100b at different height positions and with different sizes. Preferably, there are a total of two mounting plates 100b and four diagonal braces 100 a. As shown in fig. 2, 3 and 4, four diagonal braces 100a connect the mounting plates 100b to form a tower section of a stable configuration at an angle of inclination α. The mounting plate 100b is used to mount a pitch motor and/or an azimuth motor.
Second tower section 200: the opposite ends connect the first and third tower segments 100, 300 by means of connecting members in such a way that an angle of inclination α is formed. Which can be detachably attached with a fixing plate 200a for mounting an azimuth motor in such a manner as to lower the center of gravity of the antenna tower.
Third tower section 300: used for connecting with an external base body to fix the support tower.
Preferably, at least one leveling compensation shim 500 is inserted between the first tower section 100 and the second tower section 200, which is adapted to the gap between the two and can lock the connecting member. Preferably, leveling compensation shims 500 are plugged between the connecting parts of the tower body. After each tower section is installed, the height of four corners of each tower section is adjusted by additionally installing a leveling compensation gasket, so that horizontal errors generated in the installation process of the tower body can be corrected, and the rotator of the first tower section is ensured to be always kept at the horizontal position. Preferably, the leveling compensation shim is a semi-annular thin sheet structure.
Preferably, as shown in fig. 5 to 8, the leveling compensating shim 500 is U-shaped, and both ends thereof are provided with protrusions 500e protruding from the entire cross-section thereof. Preferably, the leveling shim 500 includes an inner side 500c and an outer side 500 d. The outer side surface 500d is connected to the inner side surface 500c via a transition surface 500f, a warp protrusion 500e, and a release opening 500g in this order. The transition surface 500f is connected to the insertion edge portion 500e-1 of the protrusion 500e such that the thickness thereof gradually increases from the outer surface 500d to the inner surface 500c to be higher than the first leveling surface 500 a. The insert edge portion 500e-1 is connected to a transition edge portion 500e-3 gradually spaced from the geometric centerline and gradually decreasing in thickness to be substantially flush with the first leveling plane 500a through a locking edge portion 500e-2 gradually approaching the geometric centerline of the leveling compensating pad 500, the transition edge portion 500e-3 is connected to an inner side surface 500c through a release opening 500g, and the inner side surface 500c is connected to another tilted projection 500h opposite to the tilted projection 500e in a smoothly curved manner. After each part of the tower body is installed, the horizontal positions of the bolts on all sides are compared, the bolts on the lower side are inserted into the leveling compensation gaskets 500, a plurality of leveling compensation gaskets 500 are properly added according to the error distance between the actual levels, so that the positions on the lower side are lifted to the horizontal positions, and when the bolts are screwed down, the warping protrusions 500e and the other warping protrusions 500h of the U-shaped gaskets are flattened, so that the bolt rods are clamped, and the self-locking process is realized. The tilted projection 500e and the further tilted projection 500h are used to enable the tilt angle α to approach the design value α when the first pylon segment 100 and the second pylon segment 200 are connected by the connecting member0The connecting member is locked.
Preferably, as shown in fig. 10, the release port 500g includes a first lip 500g-1 extending from the inner side 500c to the outer side 500d, a second lip 500g-2 connected to the first lip 500g-1 and extending substantially in the lengthwise direction of the leveling compensating pad 500, and a third lip 500g-3 connected to the second lip 500g-2 and extending from the outer side 500d to the inner side 500 c. The extension length of the second lip 500g-2 is set in such a manner that the release opening 500g can be elastically deformed in the case where both the locking edge portion 500e-2 and the other locking edge portion of the other seesaw projection 500h are in contact with the connection member. Therefore, the connecting parts at different positions can be locked by the leveling compensation gasket 500 by virtue of the elastic pretightening force of the release opening 500 g.
Preferably, the third leveling plane 500e-4 connected with the embedding edge portion 500e-1 and the locking edge portion 500e-2 is formed to enable the inclination angle α to approach the design value α0In such a way that they are parallel to the first leveling plane 500 a. The third tone surface 500e-4 is connected to the outer surface 500d by a relief transition surface 500e-5 having a gradually increasing thickness in a direction extending from the outer surface 500d to the inner surface 500 c.
