Description

Technical Field

[0001] This application relates to the field of communication base station repair and maintenance technology, specifically to a climbing frame for the repair of small base stations. Background Technology

[0002] A base station, or public mobile communication base station, is an interface device for mobile devices to access the Internet. It is also a type of radio station, which refers to a radio transceiver station that transmits information between a mobile communication switching center and a mobile phone terminal within a certain radio coverage area. In order to ensure a wide signal transmission and reception range, unidirectional base stations are usually installed on high supports or buildings, and lifting equipment is required for operation during maintenance.

[0003] However, existing aerial ladders lack folding or telescopic functions, resulting in a large overall volume when stored, which increases transportation costs. Furthermore, they cannot be quickly stored or unfolded, making transportation and storage difficult and inconvenient for transporting aerial ladders. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides an aerial work platform for the maintenance of small base stations, which has advantages such as easy storage. It solves the problem that existing aerial work platforms lack folding or telescopic functions, have a large overall volume when stored, which increases transportation costs, and cannot be quickly stored or unfolded, leading to difficulties in transportation and storage, and making it inconvenient to transport the aerial work platform.

[0005] To achieve the above objectives, this application provides the following technical solution: a climbing frame for small base station maintenance, comprising a base plate and a second lifting frame. A first rotating seat is fixedly connected to one side of the upper end of the base plate. Two second rotating seats arranged in a mirror image are fixedly connected to the upper end of the base plate away from the first rotating seat. Rotating blocks are rotatably arranged on both sides of the first rotating seat. A first lifting frame is fixedly connected to the outside of the two rotating blocks. Two first sliding grooves arranged in a mirror image are opened inside the first lifting frame. A first lead screw is rotatably connected inside the two first sliding grooves. Two limiting grooves arranged in a mirror image are opened on both sides of the first lifting frame. Two third rotating seats arranged in a mirror image are fixedly connected to one side of the first lifting frame. A first hydraulic rod is rotatably arranged between the two second rotating seats and the third rotating seats.

[0006] The second lifting frame has a first slider fixedly connected to one bottom end. The second lifting frame has a second slide groove on both sides inside. The two second slide grooves are rotatably connected to a second lead screw. The two ends of one side of the second lifting frame are fixedly connected to two anti-disengagement hooks arranged in a mirror distribution. The two second lead screws have working platforms on their external threads.

[0007] Through the above scheme, the first and second lead screws are respectively placed inside the first and second lifting frames. This independent design enables precise control of the height of different parts. Maintenance personnel can adjust the height of the second lifting frame and the work platform according to the actual maintenance scenario, easily handling maintenance work on small base stations of different heights. The anti-detachment hooks at both ends of one side of the second lifting frame cooperate with the limiting grooves on both sides of the first lifting frame to form a limiting and anti-detachment mechanism. During operation, this prevents the second lifting frame and the work platform from shaking or falling off, ensuring the structural stability of the entire device and reducing safety hazards caused by shaking. The setting of the first hydraulic rod not only facilitates the lifting and lowering of the first lifting frame... Hydraulic assistance is provided, and the angle of the first lifting frame can be adjusted. Maintenance personnel can easily adjust the angle of the first lifting frame by operating the hydraulic rod to adapt to different maintenance angle requirements. When storing, the first lifting frame can be rotated and folded with the first rotating seat as a fixed point by retracting the first hydraulic rod, reducing the storage volume of the device. During transportation, the folded climbing frame occupies little space, making it easy to handle and load, reducing transportation costs and improving transportation efficiency. At the same time, it also facilitates the storage and management of the device and saves storage space. The climbing frame has the advantages of stable structure, convenient operation and convenient transportation, and can meet the various needs of small base station maintenance work.

[0008] Furthermore, two fifth rotating seats arranged in a mirror image are fixedly connected to both sides of the base plate. Each of the four fifth rotating seats is rotatably connected to a support arm. The end of each of the four support arms away from the fifth rotating seat is threadedly connected to a threaded rod. The bottom end of each of the four threaded rods is rotatably connected to a support plate. The upper end of each of the four threaded rods is fixedly connected to a handle.

[0009] The above scheme involves setting two mirror-distributed fifth rotating seats on each side of the base plate, and connecting the threaded rod and the support plate with the support arm to form four support points. This multi-point support structure can increase the contact area between the climbing frame and the ground, distribute the weight of the climbing frame and the personnel and equipment on it, thereby improving the stability of the entire device during operation and reducing the risk of tipping over due to unstable center of gravity. By rotating the threaded rod, the height of the support plate can be adjusted, which allows the climbing frame to adapt to ground with different flatness.

[0010] Furthermore, the bottom end of the base plate is rotatably equipped with four movable wheels arranged in a rectangular array.

[0011] With the above solution, the four movable wheels make the entire aerial platform easy to move. Since the movable wheels are rotatable, the aerial platform can be flexibly turned. In narrow maintenance spaces or complex site environments, maintenance personnel can easily adjust the direction of movement of the aerial platform and quickly reach the maintenance position.

[0012] Furthermore, the working platform includes a movable plate, on one side of which two second sliders are fixedly connected in a mirror-shaped arrangement, and a support platform is rotatably connected to the upper end of the movable plate. On the lower end of one side of the movable plate, two mounting seats are fixedly connected in a mirror-shaped arrangement, and on the lower end of the support platform, two fourth rotating seats are fixedly connected in a mirror-shaped arrangement. A second hydraulic rod is rotatably connected between the two mounting seats and the fourth rotating seats.

[0013] With the above scheme, the support platform and the moving plate are rotatably connected, and the second hydraulic rod allows the support platform to be adjusted according to the lifting angle of the first hydraulic rod, so that the support platform always remains horizontal. The support platform provides a stable working space for maintenance personnel. The support platform can support the weight of maintenance personnel as well as the weight of maintenance tools and equipment, ensuring the safety of maintenance personnel when working at heights.

[0014] Furthermore, both first sliders are slidably disposed inside the first groove, and both first lead screws are threadedly disposed inside the first sliders.

[0015] With the above scheme, both first sliders are slidably disposed inside the first slide groove, and the first lead screw is threaded inside the first slider. When the first lead screw is rotated, the first slider will move linearly along the first slide groove, thereby driving the second lifting frame connected to it to move up and down. Maintenance personnel can adjust the second lifting frame to a suitable height according to actual maintenance needs to meet the maintenance requirements of base station equipment at different heights.

[0016] Furthermore, both second sliders are slidably disposed inside the second groove, and the interior of each second slider is threadedly connected to the second lead screw.

[0017] With the above scheme, both second sliders are slidably set inside the second slide groove, and the second sliders are threadedly connected to the second lead screw. When the second lead screw is rotated, the second sliders will move in a straight line along the second slide groove, thereby driving the work platform to move up and down. Whether it is high-altitude maintenance at the top of the base station or operation at a relatively low position in the middle, the work platform can be quickly and accurately adjusted to the required height.

[0018] Furthermore, all four anti-detachment hooks are slidably disposed inside the limiting groove.

[0019] With the above solution, during the use of the elevated platform, when adjusting the height or bearing the weight of maintenance personnel and equipment, various components may be subjected to various external forces, resulting in horizontal displacement. The sliding setting of the anti-disengagement hook in the limiting groove can limit the horizontal movement of components such as the second lifting frame, ensure the stability of the entire device structure, and prevent the safety of maintenance work from being affected by shaking or displacement.

[0020] Furthermore, both the first and second lifting frames are made of high-strength aluminum alloy.

[0021] The above solution utilizes aluminum alloy, which has a relatively low density. Compared to traditional materials such as steel, using high-strength aluminum alloy to make the lifting frame can reduce the overall weight of the device, making the lifting frame easier and more convenient to handle, move, and install, thus improving work efficiency.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This climbing frame for small base station maintenance features a first and second lead screw housed within the first and second lifting frames, respectively. This independent design allows for precise height control of different components. Maintenance personnel can adjust the height of the second lifting frame and the work platform according to the actual maintenance scenario, easily handling small base station maintenance operations at varying heights. The anti-detachment hooks on one side of the second lifting frame cooperate with the limiting grooves on both sides of the first lifting frame, forming a limiting and anti-detachment mechanism. During operation, this prevents the second lifting frame and work platform from shaking or falling off, ensuring the structural stability of the entire device and reducing safety hazards caused by shaking. The first hydraulic rod not only supports the first lifting frame... The lifting mechanism is hydraulically assisted and allows for adjustment of the angle of the first lifting frame. Maintenance personnel can easily adjust the angle of the first lifting frame by operating the hydraulic rod to adapt to different maintenance angle requirements. During storage, the first lifting frame can be rotated and folded using the first rotating seat as a fixed point by retracting the first hydraulic rod, reducing the storage volume of the device. During transportation, the folded platform occupies little space, making it easy to handle and load, reducing transportation costs and improving transportation efficiency. At the same time, it also facilitates the storage and management of the device, saving storage space. This platform has the advantages of stable structure, convenient operation, and convenient transportation, and can meet various needs of small base station maintenance work.

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] Please see Figure 1 , Figure 2 and Figure 3 The climbing frame for small base station maintenance in this embodiment includes a base plate 1 and a second lifting frame 11. A first rotating seat 2 is fixedly connected to one side of the upper end of the base plate 1. Two second rotating seats 3 arranged in a mirror image are fixedly connected to the upper end of the base plate 1 away from the first rotating seat 2. Rotating blocks 4 are rotatably arranged on both sides of the first rotating seats 2. A first lifting frame 5 is fixedly connected to the outside of the two rotating blocks 4. The first lifting frame 5 can rotate with the second rotating seats 3 as the vertices. Two first sliding grooves 6 arranged in a mirror image are opened inside the first lifting frame 5. A first lead screw 7 is rotatably connected inside the two first sliding grooves 6. The first lead screw 7 is used to drive the second lifting frame 11 to move by rotation. Two mirror-shaped limiting grooves 8 are provided on both sides of the lifting frame 5. Two mirror-shaped third rotating seats 9 are fixedly connected to one side of the first lifting frame 5. A first hydraulic rod 10 is rotatably arranged between the two second rotating seats 3 and the third rotating seats 9. The first hydraulic rod 10 not only provides hydraulic assistance for the lifting of the first lifting frame 5, but also adjusts the angle of the first lifting frame 5. Maintenance personnel can easily adjust the angle of the first lifting frame 5 by operating the hydraulic rod to adapt to different maintenance angle requirements. When storing, the first lifting frame 5 can be rotated and folded with the first rotating seat 2 as a fixed point by the retraction of the first hydraulic rod 10, reducing the storage volume of the device.

[0034] Please see Figure 1 , Figure 3 and Figure 5 The second lifting frame 11 has a first slider 12 fixedly connected to one bottom end. The second lifting frame 11 has a second slide groove 13 on both sides inside. The two second slide grooves 13 are rotatably connected to the second lead screw 14. The two anti-disengagement hooks 15 are fixedly connected to both ends of one side of the second lifting frame 11 in a mirror distribution. The anti-disengagement hooks 15 at both ends of one side of the second lifting frame 11 cooperate with the limiting grooves 8 on both sides of the first lifting frame 5 to form a limiting and anti-disengagement mechanism. During the operation, it can prevent the second lifting frame 11 and the working platform 16 from shaking or falling off, ensuring the structural stability of the entire device and reducing the safety hazards caused by shaking. The working platform 16 is provided on the external threads of the two second lead screws 14.

[0035] Please see Figure 1 , Figure 2 and Figure 4Two mirror-distributed fifth rotating seats 17 are fixedly connected to both sides of the base plate 1. Support arms 18 are rotatably connected inside each of the four fifth rotating seats 17. Threaded rods 19 are threadedly connected to the ends of the four support arms 18 away from the fifth rotating seats 17. Support plates 20 are rotatably connected to the bottom ends of the four threaded rods 19, and handles 21 are fixedly connected to the upper ends of the four threaded rods 19. The two mirror-distributed fifth rotating seats 17 on each side of the base plate 1, connected to the threaded rods 19 and support plates 20 via support arms 18, form four support points. This multi-point support structure can... Increasing the contact area between the climbing frame and the ground distributes the weight of the climbing frame, its personnel, and equipment, thereby improving the stability of the entire device during operation and reducing the risk of tipping over due to instability. The height of the support plate 20 can be adjusted by rotating the threaded rod 19, allowing the climbing frame to adapt to ground with varying flatness. Four movable wheels 22 arranged in a rectangular array are rotatably mounted on the bottom end of the base plate 1. These four wheels allow for easy movement of the entire climbing frame. Because the movable wheels 22 are rotatable, the climbing frame can be flexibly turned. In confined maintenance spaces or complex environments, maintenance personnel can easily adjust the movement direction of the climbing frame to quickly reach the maintenance location. The work platform 16 includes a movable plate 1601, with two mirror-distributed second sliders 1602 fixedly connected to one side of the movable plate 1601. A support platform 1603 is rotatably connected to the upper end of the movable plate 1601. Two mirror-distributed mounting seats 1604 are fixedly connected to the bottom end of one side of the movable plate 1601. Two mirror-distributed fourth rotating seats 1605 are fixedly connected to the bottom end of the support platform 1603. A second hydraulic rod 1606 is rotatably connected between the mounting base 1604 and the fourth rotating base 1605. The support platform 1603 and the moving plate 1601 are rotatably connected. Through the setting of the second hydraulic rod 1606, the support platform 1603 can be adjusted according to the lifting angle of the first hydraulic rod 10, so that the support platform 1603 always remains horizontal. The support platform 1603 provides a stable working space for maintenance personnel. The support platform 1603 can support the weight of maintenance personnel as well as the weight of maintenance tools and equipment, ensuring the safety of maintenance personnel when working at height.

[0036] Please see Figure 2 , Figure 3 and Figure 6Both first sliders 12 are slidably disposed inside the first slide groove 6, and both first lead screws 7 are threadedly disposed inside the first sliders 12. When the first lead screw 7 is rotated, the first slider 12 will move linearly along the first slide groove 6, thereby driving the connected second lifting frame 11 to move up and down. Maintenance personnel can adjust the second lifting frame 11 to a suitable height according to actual maintenance needs to meet the maintenance requirements of base station equipment at different heights. Both second sliders 1602 are slidably disposed inside the second slide groove 13, and both second sliders 1602 are threadedly connected to the second lead screw 14. When the second lead screw 14 is rotated, the second slider 1602 will move linearly along the second slide groove 13, thereby driving the connected second lifting frame 11 to move up and down. Maintenance personnel can adjust the second lifting frame 11 to a suitable height according to actual maintenance needs to meet the maintenance requirements of base station equipment at different heights. The work platform 16 can be moved up and down, allowing for quick and accurate adjustment to the required height for both high-altitude maintenance at the top of the base station and work at relatively low positions in the middle. Four anti-disengagement hooks 15 are slidably installed inside the limiting grooves 8. During the use of the climbing frame, when adjusting the height or bearing the weight of maintenance personnel and equipment, various components may be subjected to various external forces, resulting in horizontal displacement. The sliding installation of the anti-disengagement hooks 15 within the limiting grooves 8 restricts the horizontal movement of components such as the second lifting frame 11, ensuring the stability of the entire device structure and preventing swaying or displacement from affecting the safety of maintenance work. Both the first lifting frame 5 and the second lifting frame 11 are made of high-strength aluminum alloy. Aluminum alloy has a relatively low density, and compared to traditional materials such as steel, using high-strength aluminum alloy to make the lifting frame reduces the overall weight of the device, making the climbing frame easier and more convenient to handle, move, and install, thus improving work efficiency.

[0037] In this embodiment, the climbing frame for small base station maintenance has the first lead screw 7 and the second lead screw 14 respectively placed inside the first lifting frame 5 and the second lifting frame 11. This independent design enables precise control of the height of different parts. Maintenance personnel can adjust the height of the second lifting frame 11 and the working platform 16 according to the actual maintenance scenario, easily handling small base station maintenance operations at different heights. The anti-detachment hooks 15 at both ends of one side of the second lifting frame 11 cooperate with the limiting grooves 8 on both sides of the first lifting frame 5 to form a limiting and anti-detachment mechanism. During operation, this prevents the second lifting frame 11 and the working platform 16 from shaking or falling off, ensuring the structural stability of the entire device and reducing safety hazards caused by shaking. The first hydraulic rod 10... The design not only provides hydraulic assistance for the lifting of the first lifting frame 5, but also allows for the adjustment of the angle of the first lifting frame 5. Maintenance personnel can easily adjust the angle of the first lifting frame 5 by operating the hydraulic rod to adapt to different maintenance angle requirements. When storing, the first lifting frame 5 can be rotated and folded with the first rotating seat 2 as a fixed point by the retraction of the first hydraulic rod 10, reducing the storage volume of the device. During transportation, the folded climbing frame occupies little space, making it easy to handle and load, reducing transportation costs and improving transportation efficiency. At the same time, it also facilitates the storage and management of the device and saves storage space. The climbing frame has the advantages of stable structure, convenient operation and convenient transportation, and can meet the various needs of small base station maintenance work.

[0038] The working principle of the above embodiments is as follows:

[0039] Maintenance personnel push the climbing frame, using the four casters 22 at the bottom of the base plate 1 to move it to the vicinity of the small base station requiring maintenance. Upon reaching the designated location, they rotate the handles 21 at the top of the four threaded rods 19 to bring the four support plates 20 into contact with the ground. Adjusting the height of the support plates 20 according to the ground's flatness ensures stable placement of the device. Operating the first hydraulic rod 10 causes it to extend and retract, rotating the first lifting frame 5 around the second rotating seat 3, adjusting it to a suitable angle. Rotating the first lead screw 7 in the first slide groove 6 inside the first lifting frame 5 causes the first slider 12 to slide within the first slide groove 6, thereby moving the second lifting frame 11 up and down, adjusting it to a suitable height. Finally, rotating the second lead screw 14 in the second slide groove 13 inside the second lifting frame 11... The second lead screw 14 drives the second slider 1602 to slide within the second slide groove 13, thereby moving the work platform 16 up and down to adjust it to the required maintenance height. Based on the lifting angle of the first hydraulic rod 10, the second hydraulic rod 1606 extends and retracts, causing the support platform 1603 to rotate on the moving plate 1601, keeping the support platform 1603 level. Maintenance personnel then climb onto the support platform 1603 to perform maintenance work on the small base station. After maintenance is completed, the above steps are reversed. First, the second hydraulic rod 1606 is retracted to reset the support platform 1603. Then, the second lead screw 14 and the first lead screw 7 are rotated in the reverse direction to reset the work platform 16 and the second lifting frame 11. Next, the first hydraulic rod 10 is retracted, and the first lifting frame 5 is rotated and folded around the first rotating seat 2. Finally, the climbing frame is moved to the storage position via the moving wheels 22.
