Description

Technical Field

[0001] The present invention relates to the technical field of manufacturing and installing microwave antennas, and in particular to an auxiliary device for installing and debugging a microwave ODU. Background Art

[0002] Usually, a transition section for connecting other parts of the antenna is provided at the bottom center base hole of the antenna reflective surface of the microwave antenna. The transition section is connected to the antenna reflective surface through a center plate provided on the outside of the bottom of the reflective surface, and the ODU is indirectly connected to the antenna reflective surface through a connecting plate fixed on the center plate.

[0003] During the installation of microwave antennas, in order to ensure effective signal transmission and reception, the relative installation position of the ODU (outdoor unit) and the antenna reflector is very important. Therefore, during the installation of microwave antennas, it is usually necessary to debug the position of the connection plate and the center plate to ensure the best installation effect of the antenna. During the debugging process, it is necessary to test the relative position height of the connection plate relative to the center plate. However, since the opening of the connection plate becomes smaller after installation, it is impossible to directly test the distance between the connection plate and the center plate, so measurement and debugging are often performed indirectly.

[0004] In the prior art, such as Figure 1 As shown, after the center plate 30 and the transition section 20 are installed in place, the connection plate 10 is installed, and then the connection plate 10 is adjusted and positioned by measuring the distance S between the lower end surface of the transition section 20 and the lower end surface of the connection plate 10. In other words, the transition section as a measurement auxiliary device is used as a measurement reference to determine the position of the connection plate 10, thereby ultimately ensuring that the ODU is installed in place. However, this measurement method is not suitable for large-caliber microwave antennas or microwave antennas that use a compression-type transition section. Because the transition section of the large-aperture microwave antenna does not need to be installed in advance, the transition section currently installed as an auxiliary device during measurement needs to remove the connecting disk after measurement, take out the transition section, and then install the connecting disk on the center disk according to the determined position. This operation is not only complicated and affects work efficiency, but also there will be certain installation errors when removing and reinstalling the connecting disk at a determined position. For the clamping transition section, once the clamping transition section is installed, the connecting disk and the center disk will compress the clamping transition section between the two. In this case, the transition section cannot be used as an auxiliary measurement device. Summary of the invention

Under the control of the control shaft 2, the slider 8 can extend from the corresponding through hole to the outside of the cavity 103 or be retracted into the cavity. A baffle 5 for axially limiting the control shaft 2 is provided at the junction of the cavity 103 and the shaft hole 104.

[0028] In this embodiment, the connecting rod 7 is hinged to the corresponding end of the control shaft 2 through the hinge seat 6. A double-ear plate is correspondingly provided on the hinge seat 6, and a single-ear plate is provided at the corresponding end of the connecting rod 7. The single-ear plate is arranged inside the double-ear plate and then connected through the corresponding hinge shaft. The other end of the connecting rod 7 is a double-ear plate, which is installed in conjunction with the single-ear plate at the corresponding end of the corresponding slider.

[0029] In this embodiment, the control shaft 2 includes a large diameter section 201 and a small diameter section 202 connected as one body, the small diameter section extends into the cavity 103, and a control shaft return spring 4 is sleeved on the small diameter section between the baffle 5 and the large diameter section 201; a working positioning slot 201a is provided on the large diameter section, and a locking pin 3 for working with the working positioning slot 201a is provided on the cylindrical main body. The control shaft 2 can be integrally machined from a section of 45# steel bar stock.

[0030] The locking pin is a spring locking pin, which can adopt any structural form in the prior art that can realize the present solution.

[0031] In this embodiment, the spring locking pin 3 includes a pin shaft 301 and a compression spring 302. The pin shaft 301 is composed of an insertion portion 301a, a driving portion 301b, a spring mounting portion 301c and an operating portion 301d from one end to the other. The insertion portion 301a is spherical or conical. The diameter of the driving portion 301b is larger than that of the insertion portion 301a and the spring mounting portion 301c. The compression spring 302 is sleeved on the spring mounting portion. A countersunk hole is provided on the cylindrical main body. The spring locking pin is installed in the countersunk hole. A spring seat 303 is installed in the countersunk platform of the countersunk hole. A step is provided at one end of the countersunk hole close to the shaft hole 104 to position the pin shaft 301.

[0032] An auxiliary limiting groove 201 b for auxiliary limiting the control shaft 2 after resetting is provided on the large diameter section 201 between the working positioning groove 201 a and the small diameter section 202 .

[0033] Furthermore, a shaft shoulder 203 for auxiliary limiting the control shaft return spring 4 may be provided between the large diameter section 201 and the small diameter section 202 , and the diameter of the shaft shoulder 203 is greater than the diameter of the large diameter section 201 .

[0034] In this embodiment, the shaft hole 104 is a stepped hole, which includes a large-diameter hole matching the diameter of the large-diameter section 201 and a shoulder hole matching the diameter of the shaft shoulder 203 .

[0035] There are three through holes on the side wall of the cavity, corresponding to three connecting rods 7 and three sliding blocks 8.

[0036] The columnar main body 1 is cylindrical, and the three through holes on the side wall of the cavity are evenly arranged along the circumference of the columnar main body 1.

[0037] Specifically, the columnar main body 1 can be formed by connecting a column member 101 with a groove at the bottom and a bottom plate 102 arranged at the bottom of the column member through bolts. In this structure, the baffle 5 is also fixedly connected to the column member 101 by bolts.

[0038] The bottom plate 102 and the column member 101 together enclose the sink to form the cavity, and the through hole is formed by the radial groove arranged at the bottom of the column member 101 and the bottom plate after being installed.

[0039] When the present invention is used:

[0040] Press the control shaft 2, the control shaft 2 compresses the control shaft reset spring 4 to move downward, and drives the slider 8 to extend out of the cavity 103 from the corresponding through hole through the connecting rod 6. During the downward movement of the control shaft 2, the pin 301 in the spring pin 3 withdraws from the auxiliary limit slot 201b and is inserted into the working positioning slot 201a. Then, the end of the slider of the columnar main body 1 is inserted into the center plate opening, so that the slider 8 fits on the lower end surface of the center plate 30, and then the connecting plate 10 is installed and fixed on the center plate 30. The distance between the connecting plate 10 and the lower end surface of the columnar main body 1 is measured with the columnar main body 1 as a reference to adjust the connecting plate 10 to be installed in place.

[0041] After the measurement and adjustment is completed, the operating portion 301d of the pin 301 is pulled to make the pin 301 withdraw from the working positioning slot 201a, the control shaft reset spring 4 drives the control shaft 2 to reset, and the slider 8 is retracted. Thus, the columnar main body 1 can be withdrawn from the mouth of the center disk and the connecting disk.

[0042] In this embodiment, the extent to which the slider 8 can be extended can be determined by controlling the position of the working positioning slot 201a on the shaft 2; the reset limit of the shaft 2 can be achieved by any one of the three methods: the baffle 5, the shoulder 203 and the stepped hole, and the spring pin 3 and the auxiliary limit slot 201b. The post-installation dimensions of the columnar main body as an auxiliary measurement reference are consistent with the post-installation dimensions of the corresponding transition section to ensure that the position of the connection plate after measurement and adjustment still meets the requirements after the transition section is installed later.

[0043] For the convenience of measurement, the size of the control shaft 2 is preferably such that, after being pressed (ie, in working state), its end is completely immersed in the shaft hole 104 .

[0044] It should be noted that the above embodiments are only used to illustrate the present invention, but the present invention is not limited to the above embodiments. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention fall within the protection scope of the present invention.
