Description

Technical Field

[0001] This application relates to the field of base station antenna technology, and in particular to a base station antenna mast bottom centering device. Background Technology

[0002] During mining operations, a reliable communication system is essential for ensuring the safety and operation of the mining area. This system is typically established in open-pit locations within the mine, such as spoil heaps and tailings ponds. RTK (Real-Time Kinematic) technology, a high-precision positioning technology based on the Global Navigation Satellite System (GNSS), is widely used in establishing communication base stations in mining areas because it can provide centimeter-level or even millimeter-level positioning accuracy in a short time by processing carrier phase observations in real time.

[0003] However, during the operation of base station antenna masts in mining areas, the antenna masts are usually fixed in the open-pit mine using a pole-mounting method. This method mainly secures the upper part of the antenna mast, but no further centering or stabilization measures are taken at the bottom. Furthermore, mining operations are often accompanied by a large amount of dust, vibration, and noise. These factors, acting on the base station antenna mast for a long time, may cause it to loosen or become damaged, resulting in unstable signal reception and poor communication signal in the mining area, thereby reducing the safety of mining operations.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0030] refer to Figures 1 to 4 This application provides a base station antenna mast bottom centering device, comprising:

[0031] A horizontal base 100 is installed on a horizontal surface in the open-pit mine area, and multiple centering rods 101 are provided on its upper surface. To ensure the upper surface of the horizontal base 100 is horizontal, the location of the base station in the open-pit mine area must be constructed to be horizontal. The horizontal base 100 is made of reinforced concrete. To ensure the stability of the horizontal base 100 on the horizontal surface of the open-pit mine area, it can be fixed to the horizontal surface of the open-pit mine area using anchor bolts (not shown in the figure). Furthermore, the number of centering rods 101 and the height of each centering rod 101 can be set according to actual needs, and this application does not impose specific limitations on them.

[0032] The centering cylinder 200 includes a solid section 201 and a hollow section 202. The lower surface of the solid section 201 is provided with multiple centering holes 2011 corresponding to multiple centering rods 101, and a bearing platform 2012 is provided on its outer peripheral wall. The base station antenna mast 300 is threaded onto the hollow section 202. The bearing platform 2012 can be fixed to the outer peripheral wall of the solid section 201 by integral molding or welding. The bottom of the base station antenna mast 300 is provided with an external thread of a preset length (which can be set according to actual needs, but this application does not specifically limit it). The hollow section 202 is provided with an internal thread that matches the external thread, so that the bottom end of the base station antenna mast 300 is threadedly connected to the hollow section 202. This connection method is not only convenient for installation, but also can limit the position of the base station antenna mast 300 after it is connected to the hollow section 202, thereby improving the stability of the bottom end of the base station antenna mast 300.

[0033] A connecting ring 400 is fitted onto the base station antenna mast 300; wherein, the inner diameter of the connecting ring 400 matches the outer diameter of the base station antenna mast 300, making the connection between the connecting ring 400 and the base station antenna mast 300 more stable.

[0034] Multiple first support rods 500 are provided, with one end of each rod hinged to the upper surface of the support platform 2012 around the centering cylinder 200, and the other end connected to the outer peripheral wall of the connecting ring 400. The connection between the multiple first support rods 500 and the connecting ring 400 secures the base station antenna mast 300, further improving the stability of the base station antenna mast 300 during open-pit mining communication. The end of each first support rod 500 furthest from the support platform 2012 can be detachably fixed to the outer wall of the connecting ring 400 using bolts or other detachable means. This allows for easy removal of the end of the first support rod 500 furthest from the support platform 2012 from the connecting ring 400 when supporting and fixing base station antenna masts 300 of different diameters. The connecting ring 400 can then be replaced with one matching the diameter of the base station antenna mast 300, making it suitable for fixing base station antenna masts 300 of different diameters, and the installation process is easy to operate.

[0035] Each first support rod 500 is telescopic in length. This allows for adjustment of the position of the connecting ring 400 on the base station antenna rod 300 according to its length. The purpose is to secure the base station antenna rod 300 to multiple first support rods 500 of different lengths, thereby improving the stability of the base station antenna rod 300.

[0036] The base station antenna mast bottom alignment device provided in this application involves setting a horizontal base 100 on a horizontal surface in an open-pit mine and setting multiple alignment rods 101 on the upper surface of the horizontal base 100. The hollow section 202 of the alignment cylinder 200 is threadedly connected to the bottom of the base station antenna mast 300. The alignment cylinder 200 with the threaded connection to the base station antenna mast 300 is then lifted (a hook can be set on the top of the base station antenna mast 300 or the upper surface of the support platform 2012 for easy lifting, not shown in the figure). The multiple alignment rods 101 on the horizontal base 100 are then inserted into the solid section of the alignment cylinder 200 corresponding to the alignment rods 101. Within the centering hole 2011 of section 201, the bottom of the base station antenna mast 300 is aligned and stably supported. Simultaneously, multiple first support rods 500 are connected to the connecting ring 400 sleeved on the base station antenna mast 300, thereby fixing the mast body of the base station antenna mast 300 with multiple first support rods 500. This makes the base station antenna mast 300 more stable in the open-pit mine area, reducing the impact of dust, vibration, and noise during mining operations on the stability of the base station antenna mast, thus ensuring the stability of signal transmission during mine communication and improving the safety of mine operation.

[0037] In some embodiments, reference Figure 1 , Figure 2 and Figure 4In this application, each first support rod 500 is hinged with a second support rod 501. The end of each second support rod 501 away from the first support rod 500 is connected to the outer peripheral wall of the hollow section 202. The end of the second support rod 501 away from the first support rod 500 is detachably fixed to the outer peripheral wall of the hollow section 202 using bolts or other detachable means. This facilitates the removal of the end of the second support rod 501 away from the centering cylinder 200 when supporting and fixing the bottom of base station antenna masts 300 of different diameters using the second support rod 501 and the centering cylinder 200. This allows for the replacement of a centering cylinder 200 with one matching the diameter of the base station antenna mast 300, making it suitable for fixing base station antenna masts 300 of different diameters, and simplifying the installation process. The second support rod 501 also supports the hollow section 202 of the centering cylinder 200, thereby improving the stability of the centering cylinder 200.

[0038] In addition, the length of the second support rod 501 is telescopic, making it suitable for fixing hollow sections 202 of the centering cylinder 200 of various lengths.

[0039] In the above embodiments, both the first support rod 500 and the second support rod 501 can be electric telescopic rods or telescopic downlights, and can be set according to actual needs. This application does not make specific limitations on them.

[0040] In some embodiments, reference Figure 1 , Figure 2 and Figure 4 In this application, the outer peripheral wall of the hollow segment 202 is provided with a plurality of first connecting ears 2021 corresponding one-to-one with a plurality of second support rods 501. The end of the second support rod 501 away from the first support rod 500 is fixed to its corresponding first connecting ear 2021 by a first fixing member 600. The first fixing member 600 includes a first fastening bolt and a first nut, and each second support rod 501 and the first connecting ear 2021 are provided with a first threaded through hole that matches the first fastening bolt.

[0041] In the above embodiment, by using the screw end of the first fastening bolt and the first threaded through hole on the second support rod 501 and the first threaded through hole on the first connecting ear 2021, and by screwing the first nut onto the rod of the first fastening bolt, a fixed connection is achieved between the end of each second support rod 501 away from the first support rod 500 and the first connecting ear 2021. The above connection method facilitates installation and disassembly.

[0042] In some embodiments, reference Figure 4In this application, one of the centering holes 2011 is located at the center of the lower surface of the solid section 201, and the remaining centering holes 2011 are equally spaced around the centering hole 2011 at the center of the lower surface of the solid section 201. The centering rod 101 is matched with the centering hole 2011 to ensure the stability of the centering rod 101 within the centering hole 2011.

[0043] In the above embodiments, the distribution of the multiple centering holes 2011 makes the connection between the centering rod 101 and the centering holes 2011 more stable, thereby improving the stability of the connection between the centering cylinder 200 and the horizontal base 100, and further improving the stability of the bottom end of the base station antenna rod 300 that is threadedly connected to the hollow section 202 of the centering cylinder 200.

[0044] In some embodiments, the length of the hollow segment 202 in this application is 0.3 to 0.5 times the length of the base station antenna mast 300.

[0045] In some embodiments, the distance between the connecting ring 400 and the bottom end of the base station antenna mast 300 is greater than or equal to 2 / 3 of the length of the base station antenna mast 300.

[0046] In the above embodiments, the connecting ring 400 is provided to facilitate the support and fixation of the first support rod 500 on the pole body of the base station antenna pole 300, thereby improving the stability of the entire base station antenna pole 300 in the open-pit mine area. Since the bottom of the base station antenna pole 300 is centered and fixed, and the base station antenna pole 300 has a certain height and weight, in order to avoid too much stress on the bottom and to ensure the stability of the base station antenna pole 300, the distance between the connecting ring 400 sleeved on the base station antenna pole 300 and the bottom end of the base station antenna pole 300 is greater than or equal to 2 / 3 of the length of the base station antenna pole 300, so that the multiple first support rods 500 can fix the pole body of the base station antenna pole 300. The specific sleeve position of the connecting ring 400 on the base station antenna pole 300 can be set according to actual needs, and this application does not specifically limit it here.

[0047] In some embodiments, reference Figure 1 , Figure 2 and Figure 4The connecting ring 400 in this application includes two semi-circular retaining rings 401. Specifically, each retaining ring 401 has a second connecting lug 4011 at both ends, and the two corresponding second connecting lugs 4011 on the two retaining rings 401 are fixed together by a second fastener 700. The second fastener 700 includes a second fastening bolt and a second nut, and each second connecting lug 4011 has a second threaded through hole that matches the second fastening bolt. Specifically, the inner peripheral walls of the two retaining rings 401 are pressed tightly against the outer peripheral wall of the base station antenna mast 300, and the screw end of the second fastening bolt passes through the second threaded through hole of the two second connecting lugs 4011 in sequence. Then, the second nut is screwed onto the shaft of the second fastening bolt, thereby fixing the connecting ring 400 on the base station antenna mast 300. The above connection method facilitates installation and disassembly.

[0048] In addition, each retaining ring 401 has multiple third connecting ears 4012 on its outer peripheral wall, corresponding to the multiple first support rods 500. The end of each first support rod 500 away from the support platform 2012 is fixed to its corresponding third connecting ear 4012 by a third fastener 800. The third fastener 800 includes a third fastening bolt and a third nut. Both the end of each first support rod 500 away from the support platform 2012 and the third connecting ear 4012 have a third threaded through hole that matches the third fastening bolt. The third fastening bolt passes through the third threaded through hole on the first support rod 500 and the third threaded through hole on the third connecting ear 4012 in sequence. Then, the third nut is screwed onto the rod of the third fastening bolt. This achieves a fixed connection between the end of the first support rod 500 away from the support platform 2012 and the retaining ring 401. The above connection method is convenient for installation and disassembly and can be applied to the support and fixation of base station antenna masts 300 of different diameters.

[0049] In some embodiments, reference Figure 2 and Figure 3 In this application, ladders 900 are provided on the horizontal base 100, the centering cylinder 200, and the base station antenna mast 300. The ladders 900 extend along the height of the horizontal base 100, the length of the centering cylinder 200, and the length of the base station antenna mast 300.

[0050] In the above embodiments, the ladder 900 facilitates workers to climb onto the horizontal base 100, the centering cylinder 200, and the base station antenna mast 300 to install and fix the various structural components included in the base station antenna mast bottom centering device of this application, avoiding the need for additional handling of the installation ladder and improving the ease of installation of the base station antenna mast bottom centering device.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
