[0030] To solve the problems that the existing lifting structures of communication base stations have a large occupied space and are inconvenient to install in narrow places, the present invention provides a supporting device for a communication base station, which can save the occupied space and is convenient to install in narrow places. The following is a detailed description through specific embodiments.

[0031] As Figure 1 and Figure 3 shown, the supporting device for a communication base station includes: a mounting plate 1, a sleeve 3, a support rod 4, a driving mechanism and a bottom plate 2.

[0032] Among them, the upper surface of the mounting plate 1 is used to mount the communication base station, and the lower surface of the mounting plate 1 is connected to the top of the sleeve 3. The bottom of the support rod 4 is connected to the upper surface of the bottom plate 2. The sleeve 3 is sleeved on the support rod 4 and is slidably connected to the support rod 4. The driving mechanism is respectively connected to the sleeve 3 and the support rod 4 and is used to drive the sleeve 3 to move up and down along the support rod 4. It can be seen that the mounting plate 1 is fixed to the top of the sleeve 3, the sleeve 3 is slidably arranged up and down on the support rod 4, and the bottom of the support rod 4 is fixed to the bottom plate 2.

[0033] In this embodiment, the support device is slidably connected through the sleeve and the support rod, and drives the sleeve to move up and down along the support rod, meeting the lifting requirements of the communication base station. At the same time, the support device adopting this lifting structure has the advantage of small overall occupied space, and the installation process of the communication base station is straight up and down, and it has a good installation effect even in narrow places.

[0034] In a specific embodiment, as Figure 3 shown, the driving mechanism includes: a rack 7, an output gear 8, a power input structure and a power transmission structure.

[0035] Among them, the rack 7 is arranged on the inner surface of the sleeve 3 and extends along the length direction of the sleeve 3. The output gear 8 is arranged on the upper part of the side surface of the support rod 4 and is meshed and connected with the rack 7. The power input structure is connected to the power transmission structure and is used to input power to the power transmission structure. The power transmission structure is also connected to the output gear 8 and is used to transmit the input power to the output gear 8 to drive the output gear 8 to rotate.

[0036] In this embodiment, the rack 7 is fixed inside the sleeve 3, the upper part of the support rod 4 is rotatably provided with the output gear 8, and the rack 7 is meshed and connected with the output gear 8, realizing the sliding connection between the sleeve 3 and the support rod 4. This connection form of driving the rack to move up and down by the rotation of the gear makes the entire support device only occupy the upper space and has a small occupied space. Moreover, the gear-rack mechanism has a stable transmission ratio, a constant pressure angle, high transmission efficiency, and a stable overall structure, which can improve the wind resistance ability.

[0037] In a specific embodiment, as Figure 1 and Figure 2 shown, at least one side surface of the support rod 4 is provided with a guide rail 5 extending along the length direction of the support rod 4, and a chute 6 matching the guide rail 5 is fixedly arranged at a position corresponding to the guide rail 5 on the inner surface of the sleeve 3.

[0038] In this embodiment, there are two guide rails 5. One guide rail 5 is arranged on the side of the support rod 4 where the output gear 8 is provided, and the other guide rail 5 is arranged on the other side of the support rod 4 opposite to the side where the output gear 8 is provided. Correspondingly, there are also two sliding grooves 6. One sliding groove 6 is arranged on a side of the sleeve 3 adjacent to the side where the rack 7 is provided and matches one guide rail 5, and the other sliding groove 6 is arranged on the other side of the sleeve 3 adjacent to the side where the rack 7 is provided and matches the other guide rail 5, that is, the two sliding grooves 6 are respectively arranged on two sides of the sleeve 3 adjacent to the side where the rack 7 is provided, and the two adjacent sides are perpendicular to the side where the rack 7 is provided. The sliding connection between the support rod 4 and the sleeve 3 is realized through the cooperation of the guide rail and the sliding groove, which can make the lifting process of the sleeve 3 more stable.

[0039] In a specific embodiment, as Figure 1 , Figure 2 and Figure 3 shown, a first upper limit block (not shown in the figure) is arranged at the position on the side of the support rod 4 corresponding to the top of the guide rail 5, and a first lower limit block 23 is arranged at the position on the side of the support rod 4 corresponding to the bottom of the guide rail 5. At least one second limit block is arranged on the inner surface of the sleeve 3, and the second limit block can be arranged on the other side of the sleeve 3 opposite to the side where the rack is provided. Each second limit block is arranged between the first upper limit block and the first lower limit block 23.

[0040] In this embodiment, two second limit blocks are adopted. As Figure 3 shown, they are respectively a second upper limit block 26a and a second lower limit block 26b, and the second upper limit block 26a is located above the second lower limit block 26b. Among them, when the sleeve 3 is driven to move upward along the support rod 4, the second upper limit block 26a cooperates with the first upper limit block to prevent the sleeve 3 from rising excessively and causing a failure; when the sleeve 3 is driven to move downward along the support rod 4, the second lower limit block 26b cooperates with the first lower limit block 23 to prevent the sleeve 3 from descending excessively and causing a failure.

[0041] Of course, even if only one second limit block is arranged in the sleeve 3, it can prevent the failure caused by the excessive rise / descent of the sleeve 3. As for the specific number of the second limit blocks arranged and their actual arrangement positions, those skilled in the art can set and adjust them according to actual needs.

[0042] In a specific embodiment, as Figure 4 shown, the power input structure includes: an input shaft 16, an input gear 15 and a driving component. The power transmission structure includes: an output shaft 9, an output sprocket 10, a roller chain 11, an input sprocket 12, an intermediate shaft 13 and an intermediate gear 14.

[0043] Among them, the input gear 15 is fixedly sleeved on the input shaft 16, the input sprocket 12 and the intermediate gear 14 are respectively fixedly sleeved on the intermediate shaft 13, and the intermediate gear 14 is meshed and connected with the input gear 15. The output gear 8 and the output sprocket 10 are respectively fixedly sleeved on the output shaft 9, and the input sprocket 12 and the output sprocket 10 are meshed and connected through a roller chain 11. The driving assembly is connected to the input shaft 16 and is used to drive the input shaft 16 to rotate. In other words, the output gear 8 is connected to the input shaft 16 through a set of transmission components.

[0044] Specifically, the output shaft 9 is supported on the upper part of the support rod 4 and is rotatably connected to the upper part of the support rod 4. The intermediate shaft 13 is supported on the lower part of the support rod 4 and is rotatably connected to the lower part of the support rod 4. Further, the intermediate shaft 13 passes through the opposite sides of the lower part of the support rod 4 and both ends are exposed. The input sprocket 12 is sleeved on the part of the intermediate shaft 13 exposed on one side of the support rod 4, and the intermediate gear 14 is sleeved on the part of the intermediate shaft 13 exposed on the other side of the support rod 4.

[0045] In this embodiment, in order to transmit power to the output gear 8, the driving assembly drives the input shaft 16 to rotate. The rotation of the input shaft 16 will drive the input gear 15 sleeved thereon to rotate. The rotation of the input gear 15 will drive the intermediate gear 14 meshed therewith to rotate. The rotation of the intermediate gear 14 will drive the intermediate shaft 13 to rotate. The rotation of the intermediate shaft 13 will drive the input sprocket 12 sleeved thereon to rotate. The rotation of the input sprocket 12 will drive the roller chain 11 meshed therewith to rotate. The rotation of the roller chain 11 will drive the output sprocket 10 meshed therewith to rotate. The rotation of the output sprocket 10 will drive the output shaft 9 to rotate. The rotation of the output shaft 9 will drive the output gear 8 sleeved thereon to rotate. The rotation of the output gear 8 will drive the rack 7 meshed therewith to move up and down, so as to achieve the purpose of lifting the communication base station.

[0046] In a specific embodiment, as Figure 4 shown, the radius of the input sprocket 12 is smaller than the radius of the output sprocket 10, and the radius of the input gear 15 is smaller than the radius of the intermediate gear 14.

[0047] In this embodiment, the radius of the input sprocket 12 is smaller than the radius of the output sprocket 10, and the radius of the input gear 15 is smaller than the radius of the intermediate gear 14, which can reduce the rotational speed and increase the torque, thus achieving the effect of saving effort.

[0048] In a specific embodiment, as Figure 1 and Figure 3 shown, a protective cover 22 is arranged outside the input gear 15 and the intermediate gear 14. The protective cover 22 can adopt a hollow structure with an open bottom, and the bottom of the protective cover 22 is fixed on the bottom plate 2.

[0049] In this embodiment, the input gear 15 and the intermediate gear 14 are accommodated inside the protective cover 22, which can protect the input gear 15 and the intermediate gear 14 and effectively avoid mechanical injuries at the same time.

[0050] In a specific embodiment, as Figures 3 to 6 shown, the drive assembly includes: a limit wheel 17, a drive sprocket 18, and an endless chain 21.

[0051] Among them, the limit wheel 17, the drive sprocket 18, and the input gear 15 are sequentially sleeved on the input shaft 16. A section of thread 29 is provided on the input shaft 16. The drive sprocket 18 is connected to the input shaft 16 through the thread 29. The limit wheel 17 is provided at one end of the thread 29 on the input shaft 16. The endless chain 21 is sleeved on the drive sprocket 18 and is meshed and connected with the drive sprocket 18, and the circumference of the endless chain 21 is greater than the circumference of the drive sprocket 18.

[0052] In this embodiment, by fixedly sleeving the limit wheel 17 on the side of the drive sprocket 18 on the input shaft 16 away from the input gear 15, the drive sprocket 18 can be effectively prevented from disengaging from the thread 29 during the reverse rotation.

[0053] In a specific embodiment, as Figure 1 and Figure 3 shown, the drive assembly is arranged inside a housing 24 with an open bottom, that is, the housing 24 adopts a hollow structure with an open bottom. The bottom of the housing 24 is fixed on the bottom plate 2. The input shaft 16 is supported inside the housing 24 and is rotatably connected to the inner surface of the housing 24.

[0054] A first elongated hole 25a is opened at a position on one side of the housing 24 corresponding to the drive sprocket 18. The first elongated hole 25a extends downward to the bottom edge of the housing 24. A second elongated hole 25b is opened at a position on the bottom plate 2 corresponding to the drive sprocket 18. The second elongated hole 25b extends outward to the edge of the bottom plate 2, and the first elongated hole 25a communicates with the second elongated hole 25b. The limit wheel 17, the drive sprocket 18, and the part of the endless chain 21 sleeved on the drive sprocket 18 are accommodated inside the housing 24, while the rest of the endless chain 21 extends outwards from the first elongated hole 25a on the housing 24 and the second elongated hole 25b on the bottom plate 2, facilitating the staff to pull the endless chain 21.

[0055] In this embodiment, a second strip-shaped hole 25b is formed in the bottom plate 2, and the second strip-shaped hole 25b is arranged below the driving sprocket 18. A first strip-shaped hole 25a is also formed in the side surface of the housing 24, and the first strip-shaped hole 25a is arranged on the side surface (or in front of) the driving sprocket 18. An endless chain 21 is sleeved on the driving sprocket 18. By pulling the endless chain 21 exposed from the first strip-shaped hole 25a and the second strip-shaped hole 25b, the staff can drive the sleeve 3 to lift and lower through the driving mechanism. The endless chain 21 can use models with different lengths to adapt to different application scenarios.

[0056] In a specific embodiment, as Figure 6 shown, the driving assembly further includes: a friction wheel 19 and a ratchet assembly. The friction wheel 19 and the ratchet assembly are also accommodated in the housing 24. The housing 24 can protect the driving assembly accommodated therein and effectively avoid mechanical injuries at the same time.

[0057] Among them, the friction wheel 19 and the ratchet assembly are also sleeved on the input shaft 16. The two are located between the driving sprocket 18 and the input gear 15, and the friction wheel 19 is located between the driving sprocket 18 and the ratchet assembly, that is, the limiting wheel 17, the driving sprocket 18, the friction wheel 19, the ratchet assembly and the input gear 15 are sequentially sleeved on the input shaft 16. The friction wheel 19 is arranged at the other end of the thread 29 on the input shaft 16.

[0058] In this embodiment, by pulling the endless chain 21 in the first direction, the driving sprocket 18 is driven to rotate forward, so that the driving sprocket 18 gradually approaches the friction wheel 19 on the input shaft 16 until the friction wheel 19 and the ratchet assembly are pressed tightly, and the input shaft 16 is driven to rotate forward. During this process, affected by the ratchet assembly, the input shaft 16 can only rotate in one direction. By pulling the endless chain 21 in the second direction opposite to the first direction, the driving sprocket 18 is driven to rotate reversely, so that the driving sprocket 18 gradually moves away from the friction wheel 19 and gradually approaches the limiting wheel 17 on the input shaft 16 to release the friction wheel 19 and the ratchet assembly. At this time, the input shaft 16 can rotate freely.

[0059] It can be seen that the connection and disconnection between the input shaft 16 and the ratchet assembly are controlled by the thread 29 and the friction wheel 19. When the input shaft 16 rotates reversely quickly to make the sleeve 3 descend, and then the driving sprocket 18 is rotated forward until the driving sprocket 18 presses the friction wheel 19 and the ratchet assembly tightly, the input shaft 16 can be quickly connected to the ratchet assembly, which plays a role in braking during the descent of the communication base station, preventing the communication base station from descending too fast and having a good protection effect on the communication base station.

[0060] In a specific embodiment, the ratchet assembly includes: a ratchet 20, a pawl 27 and a reset member.

[0061] Among them, the ratchet wheel 20 is sleeved on the input shaft 16. The ratchet wheel 20 can rotate freely on the input shaft 16. The pawl 27 is located above the ratchet wheel 20 and is rotatably arranged on the inner side surface of the housing 24. The ratchet wheel 20 and the pawl 27 are matched. The reset member is connected to the pawl 27.

[0062] As Figure 7 shown, the reset member adopts a reset spring 28. The pawl 27 is arranged above the ratchet wheel 20. The end of the pawl 27 is rotatably arranged on the inner side surface of the housing 24. One end of the reset spring 28 is connected to an appropriate position on the inner side surface of the housing 24, and the other end of the reset spring 28 is connected to the pawl 27, which is used to continuously reset the pawl 27 during the relative movement between the pawl 27 and the ratchet wheel 20.

[0063] In this embodiment, the tooth profile of the ratchet wheel 20 is designed as a one-way tooth. When the input shaft 16 drives the ratchet wheel 20 to rotate forward, the pawl 27 will slide along with the rotation of the ratchet wheel 20 and will not hinder the forward rotation of the ratchet wheel 20; while when the ratchet wheel 20 attempts to rotate backward, the pawl 27 will snap into the tooth groove of the ratchet wheel 20 to prevent the ratchet wheel 20 from rotating backward, thereby stopping the reverse rotation of the input shaft 16.

[0064] The working principle of the supporting device of the communication base station in this embodiment is as follows:

[0065] After installing the communication base station on the mounting plate 1, the bottom plate 2 can be fixed on the ground or on the mounting bracket. According to the needs of the working space, use a ring chain 21 with a suitable length, pull the ring chain 21 forward, drive the sleeve 3 to rise through the driving mechanism, and drive the communication base station to rise until it reaches the appropriate position to complete the work. Then, the ring chain 21 can be removed or stored. When the communication base station needs to be lowered, pull the ring chain 21 backward to drive the drive sprocket 18 to rotate reversely. The drive sprocket 18 moves along the direction away from the ratchet wheel 20 on the input shaft 16 to release the ratchet wheel 20, and drives the input shaft 16 to rotate rapidly in reverse, thereby driving the sleeve 3 to descend through the driving mechanism and driving the communication base station to descend. During the descent, the ring chain 21 can be pulled forward again to make the drive sprocket 18 move along the direction close to the ratchet wheel 20 on the input shaft 16 to press the ratchet wheel 20, and the sleeve 3 can be prevented from continuing to descend.

[0066] The support device for a communication base station provided by an embodiment of the present invention realizes the sliding connection between the sleeve and the support rod through the form of gear-rack transmission, so that the entire support device occupies less space above. The installation process of the communication base station is straight up and down, and it has a good installation effect even in narrow places. Moreover, the gear-rack mechanism has a stable transmission ratio, a constant pressure angle, high transmission efficiency, and a stable overall structure, which can improve the wind resistance. The connection and disconnection between the input shaft and the ratchet are controlled by threads and friction wheels. When the input shaft rotates quickly in the reverse direction to lower the sleeve, the driving sprocket is rotated forward until the driving sprocket presses against the friction wheel and the ratchet assembly, and the input shaft can be quickly connected to the ratchet assembly, playing a role in braking during the descent of the communication base station to prevent the communication base station from descending too fast, and having a good protection effect on the communication base station.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
