Description

Technical Field

[0001] This invention relates to the field of automatic lifting technology, and in particular to an automatic lifting device for antenna array erection. Background Technology

[0002] The erection and dismantling of antenna array equipment requires the assistance of lifting equipment to achieve automated lifting and ensure the safety and stability of the antenna array equipment itself.

[0003] Traditional lifting equipment typically uses simple electric lifting platforms to achieve lifting functions. However, in actual use, there are often some problems, such as insufficient safety protection functions, difficulty in safely stopping the lifting operation at any time in an emergency, the inability to operate remotely and the inability to operate manually on-site during a power outage, and the inability to provide sufficient locking effect for the antenna array equipment after it is raised into position. These problems all pose certain safety hazards to the lifting equipment and the antenna array equipment itself. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic lifting device for antenna array erection.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

Guide rails are provided on the opposite surfaces of the two uprights, and a lifting base is slidably arranged between the two guide rails. Four fixed anchor points are fixedly connected to the bottom of the lifting base, and two fixed anchor points are fixedly connected to the top of the lifting base. A platform is fixedly installed on the side wall of the lifting base through a frame. A locking mechanism including a push rod is inclinedly arranged on the side wall of the frame.

[0008] The fixed ends of the electric lifting rods are fixedly installed on both sides of the top of the base frame. A connecting block is fixedly connected to one side of the top of the telescopic end of the electric lifting rod. The top two sides of the top of the telescopic end of the electric lifting rod are rotatably connected to the rising pulleys. The bottom of the connecting block is rotatably connected to the descending pulleys. A lifting cable is installed on the rising pulley. One end of the lifting cable is installed on the top of the base frame by a lock. The other end of the lifting cable is installed on the fixed anchor point at the bottom of the lifting base by a lock. A retrieval cable is installed on the descending pulley. One end of the retrieval cable is installed on the top of the back frame by a lock. The other end of the retrieval cable is installed on the fixed anchor point at the top of the lifting base by a lock. A lever is fixedly connected to the outer ring side wall of both the rising pulley and the descending pulley.

[0009] Preferably, the base frame is welded with fixed lugs around its perimeter, and the top of the upright frame is provided with a positioning pin.

[0010] Preferably, the outer rings of the two side walls of the lifting base are rotatably connected to a plurality of main guide wheels, and the inner rings of the two side walls of the lifting base are rotatably connected to a plurality of side guide wheels. The main guide wheels are rolledly connected to the side walls of the guide rails, and the side guide wheels are rolledly connected to the opposite surfaces of the two guide rails.

[0011] Preferably, the platform has an opening at its top, and the top of the opening has several installation interfaces, and a sealing ring is provided on the outer ring of the platform.

[0012] Preferably, an inverted L-shaped fixing block is fixedly connected to the bottom of the mounting plate, a connecting column is fixedly connected between the ends of the two push plates, the end of the fixing block is located between the connecting column and the end of the push rod, and a guide rod is fixedly connected to the bottom of the end of the fixing block.

[0013] Preferably, the push rod is a screw structure, and the push rod is driven by a motor reducer.

[0014] Preferably, the push plate has a groove on the side near the fixed stop that is slidably connected to the guide rod. The side of the groove near the push rod has an arc-shaped structure, and the side of the groove away from the push rod has a straight structure.

[0015] Preferably, the length of the connecting block is greater than the length of the fixed end of the electric lifting rod. The two electric lifting rods are driven by a motor and a reducer fixedly installed at the center of the top of the base frame. A manual reducer interface is provided on one side of the reducer.

[0016] Preferably, the lubrication mechanism includes an oil tank and a movable rod. The oil tank is fixedly installed on both sides of the top end of the telescopic end of the electric lifting rod. An oil port is provided at the bottom of one side of the oil tank. The end of the oil port is directly opposite the center of the rising pulley. The oil port is connected to the internal channel of the oil tank. A movable rod is slidably connected to one side of the channel. The top of the movable rod abuts against a spring that abuts against the inside of the oil tank. A through hole adapted to the channel is opened in the middle of the movable rod. The channel is located at the top of the movable rod.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] This invention employs a lifting mechanism with the lifting and retraction cables moving in opposite directions, creating a mutual constraint and locking effect. The lifting and retraction cables can only be activated by the raising and lowering of the electric lifting rod, preventing accidental slippage due to cable slack. Furthermore, the screw structure of the electric lifting rod itself has a self-locking effect, preventing the lifting base and platform from falling. This effect also allows the lifting base to self-lock at any height within its travel range, greatly improving the stability and safety of the device. A manual reducer interface allows for manual rotation of the reducer using external tools during power outages, facilitating the smooth lifting and lowering of the antenna array equipment.

[0019] This invention incorporates a locking mechanism that locks the hook of the antenna array device after it is raised to the correct position. A fixed stop abuts against the side wall of the hook, facilitating the locking mechanism to tighten the hook and preventing it from disengaging, thus improving the locking effect of the locking mechanism on the antenna array device. A connecting post is used to connect with the hook. Through the cooperation of the guide rod and the slide groove, when the push rod pushes the push plate outward, the push plate can move outward and rotate, making it easy for the hook to hook onto the connecting post. Conversely, when the push rod pulls the push plate to retract, the slide groove drives the push plate to reverse and reset, thus firmly locking the hook between the connecting post and the fixed stop and fully compressing it. At the same time, it compresses the sealing ring, thereby improving the sealing and protection effects.

[0020] This invention incorporates a lubrication mechanism. During the lifting and lowering process, both the rising and lowering pulleys are driven to rotate by the lifting and retrieving cables. During this rotation, a lever periodically actuates the movable rod, causing it to rise against the spring force. As the movable rod rises, the through-hole connects to the internal channel of the oil tank, allowing lubricating oil to flow out of the oil port and ultimately drip into the grooves of the rising and lowering pulleys, lubricating the lifting and retrieving cables. This enables the device to automatically lubricate the lifting and retrieving cables, eliminating the need for manual lubrication during use. This simplifies operation, increases automation, and provides maintenance for the lifting and retrieving cables during automatic lubrication, reducing wire rope aging and wear.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] Reference Figures 1-10An automatic lifting device for antenna array erection includes a back frame 2 and a platform 10. Uprights 1 are fixedly connected to both sides of the back frame 2. A base frame 3 is fixedly connected between the bottoms of the two uprights 1. Guide rails 5 are provided on the opposite sides of the two uprights 1. A lifting base 6 is slidably arranged between the two guide rails 5. Four fixed anchor points 9 are fixedly connected to the bottom of the lifting base 6. Two fixed anchor points 9 are fixedly connected to the top of the lifting base 6. The platform 10 is fixedly installed on the side wall of the lifting base 6 through a frame 13. A locking mechanism 14 including a push rod 18 is inclinedly arranged on the side wall of the frame 13. A lifting mechanism 22 including an electric lifting rod 23 is provided at the top of the base frame 3. Lubrication mechanisms 29 are provided on both sides of the top end of the telescopic end of the electric lifting rod 23.

[0034] Four inclined mounting plates 17 are fixedly connected to the side wall of the frame 13. A push rod 18 is rotatably connected to the bottom of the mounting plate 17. Two push plates 20 are rotatably connected to the end of the push rod 18. Four hooks 16 are fixedly installed at the bottom of the antenna array.

[0035] The fixed ends of the electric lifting rod 23 are fixedly installed on both sides of the top of the base frame 3. A connecting block 231 is fixedly connected to one side of the top of the telescopic end of the electric lifting rod 23. The rising pulley 24 is rotatably connected to both sides of the top of the telescopic end of the electric lifting rod 23. A descending pulley 25 is rotatably connected to the bottom of the connecting block 231. A lifting cable 27 is installed on the rising pulley 24. One end of the lifting cable 27 is installed on the top of the base frame 3 by a lock. The other end of the lifting cable 27 is installed on the fixed anchor point 9 at the bottom of the lifting base 6 by a lock. A recovery cable 28 is installed on the descending pulley 25. One end of the recovery cable 28 is installed on the top of the back frame 2 by a lock. The other end of the recovery cable 28 is installed on the fixed anchor point 9 at the top of the lifting base 6 by a lock. A lever is fixedly connected to the outer side wall of both the rising pulley 24 and the descending pulley 25. The lifting cable 27 and the retrieval cable 28 are made of steel wire rope. The lifting cable 27 and the retrieval cable 28 are in opposite directions, thus creating a mutual constraint and locking effect. The lifting cable 27 and the retrieval cable 28 can only be moved by the raising and lowering of the electric lifting rod 23, in order to prevent the lifting cable 27 from becoming loose and disengaging in case of an accident. In addition, the screw structure of the electric lifting rod 23 itself has a self-locking effect, which can also prevent the lifting base 6 and the platform 10 from falling. This effect also allows the lifting base 6 to self-lock at any height within the stroke range, greatly improving the stability and safety of the device. The locking mechanism 14 is used to lock the hook 16 of the antenna array equipment after it is raised to the position.

[0036] As a technical optimization of the present invention, the base frame 3 is welded with fixing lugs 4 around its perimeter, and the top of the upright frame 1 is provided with a positioning pin. The fixing lugs 4 are used to fix the upright frame 1.

[0037] As a technical optimization of the present invention, a plurality of main guide wheels 7 are rotatably connected to the outer rings of both side walls of the lifting base 6, and a plurality of side guide wheels 8 are rotatably connected to the inner rings of both side walls of the lifting base 6. The main guide wheels 7 are rolledly connected to the side walls of the guide rails 5, and the side guide wheels 8 are rolledly connected to the opposing surfaces of the two guide rails 5. The lifting base 6 is rolledly connected to the guide rails 5 through the main guide wheels 7 and the side guide wheels 8, which can greatly reduce vibration during the lifting and lowering process and effectively improve the stability and reliability of the lifting.

[0038] As a technical optimization of the present invention, the platform 10 has an opening at its top, and a plurality of mounting interfaces 11 are provided at the top of the opening. A sealing ring 12 is provided on the outer ring of the platform 10. The mounting interfaces 11 are used to install antenna array equipment, and the sealing ring 12 facilitates waterproofing and reduces corrosion and other problems.

[0039] As a technical optimization of the present invention, an inverted L-shaped fixing block 19 is fixedly connected to the bottom of the mounting plate 17, and a connecting post is fixedly connected between the ends of the two push plates 20. The end of the fixing block 19 is located between the connecting post and the end of the push rod 18, and a guide rod is fixedly connected to the bottom of the end of the fixing block 19. The fixing block 19 is used to abut against the side wall of the hook 16 to facilitate the locking mechanism 14 to tighten the hook 16, prevent the hook 16 from disengaging, and improve the locking effect of the locking mechanism 14 on the antenna array equipment. The connecting post is used to hook with the hook 16.

[0040] As a technical optimization of the present invention, the push rod 18 is a screw structure, and the push rod 18 is driven by the motor reducer 15. The screw structure of the push rod 18 helps to increase the locking force of the locking mechanism 14, and the self-locking effect of the screw effectively prevents the hook 16 from disengaging due to slippage and other problems, thereby improving the safety of the equipment.

[0041] As a technical optimization of the present invention, the push plate 20 has a groove 21 on the side near the fixed stop 19 that is slidably connected to the guide rod. The side of the groove 21 near the push rod 18 has an arc-shaped structure, and the side of the groove 21 away from the push rod 18 has a straight structure. With the cooperation of the guide rod and the groove 21, when the push rod 18 pushes the push plate 20 outward, the push plate 20 can move outward and rotate, making it easy for the hook 16 to hook onto the connecting column. Conversely, when the push rod 18 pulls the push plate 20 to retract, the groove 21 drives the push plate 20 to reverse and reset, which can firmly lock the hook 16 between the connecting column and the fixed stop 19 and fully compress it. At the same time, it compresses the sealing ring 12, thereby improving the sealing effect and protection effect.

[0042] As a technical optimization of the present invention, the length of the connecting block 231 is greater than the length of the fixed end of the electric lifting rod 23. The two electric lifting rods 23 are driven by a motor and a reducer fixedly installed at the center of the top of the base frame 3. A manual reducer interface 26 is provided on one side of the reducer. The manual reducer interface 26 is used to connect an external manual tool to manually rotate the reducer in the event of a power outage, facilitating the smooth lifting and lowering operation of the antenna array equipment.

[0043] As a technical optimization of the present invention, the lubrication mechanism 29 includes an oil tank 30 and a movable rod 32. The oil tank 30 is fixedly installed on both sides of the top end of the telescopic end of the electric lifting rod 23. An oil port 31 is provided at the bottom of one side of the oil tank 30. The end of the oil port 31 is directly opposite the center of one side of the rising pulley 24. The oil port 31 is connected to the internal channel of the oil tank 30. The movable rod 32 is slidably connected to one side of the channel. The top of the movable rod 32 abuts against the inside of the oil tank 30. A through hole 33 adapted to the channel is opened in the middle of the movable rod 32. The channel is located at the top of the movable rod 32. During the lifting and lowering process, both the rising pulley 24 and the lowering pulley 25 are driven to rotate by the lifting cable 27 and the recovery cable 28. During this rotation, the lever can periodically move the movable rod 32, causing the movable rod 32 to rise against the force of the spring 34. As the movable rod 32 rises, the through hole 33 can connect with the internal channel of the oil tank 30, allowing lubricating oil to flow out of the oil port 31 and finally drip into the grooves of the rising pulley 24 and the lowering pulley 25 to lubricate the lifting cable 27 and the recovery cable 28. This allows the device to achieve automatic lubrication of the lifting cable 27 and the recovery cable 28 without the need for manual addition of lubricating oil during use. This not only facilitates operation but also improves the degree of automation. Furthermore, it can maintain the lifting cable 27 and the recovery cable 28 during automatic lubrication, reducing the aging and wear of the wire rope.

[0044] In use, the platform 10 and the lifting base 6 are initially in a lowered state, i.e., at the bottom of the support frame 1. The support frame 1 is installed in a predetermined position using the fixed lugs 4. The antenna array equipment is installed on the mounting interface 11 in the middle of the platform 10. The electric lifting rods 23 are started by starting the motor and the reducer. The telescopic ends of the two electric lifting rods 23 push the four rising pulleys 24, the connecting block 231, and the two descending pulleys 25 to rise. Since one end of the lifting cable 27 is fixed and the other end is connected to the fixed anchor point 9 at the bottom of the lifting base 6, the rising pulleys 24 can pull the lifting base 6, the platform 10, and the antenna array equipment to rise through the lifting cable 27. The recovery cable 28 moves accordingly. During the rise, the main guide wheel 7 and the side guide wheel 8 roll upward along the side wall and vertical plane of the guide rail 5. Under the action of gravity, the lifting cable 27 and the recovery cable 28 are both in a taut state. When the elevator 24 rises, the lifting cable 27 drives the lifting pulley 24 to rotate. The lever on the outer side wall of the lifting pulley 24 rotates synchronously, which periodically actuates the bottom of the movable rod 32, causing the movable rod 32 to rise against the force of the spring 34. This periodically connects the through hole 33 with the internal channel of the oil tank 30, allowing the lubricating oil stored in the oil tank 30 to flow into the oil port 31 through the channel and drip into the groove of the lifting pulley 24 to lubricate the lifting cable 27. Similarly, an oil tank 30 with the same structure can be installed above the descending pulley 25 to lubricate the recovery cable 28. Since each lifting pulley 24 is a single movable pulley, the lifting stroke of its lifting base 6 is 2:1 with the extension stroke of the electric lifting rod 23. Therefore, after the electric lifting rod 23 rises to its position, the lifting base 6 at the bottom of the electric lifting rod 23 can be synchronously lifted to the top of the extension end of the electric lifting rod 23.

[0045] After the platform 10 is raised into position, the antenna array equipment needs to be locked in place. The motor reducer 15 is started to push the push rod 18 and the push plate 20 to extend outward. During the process, the push plate 20 is rotated while extending outward through the guide rod and the slide groove 21, which facilitates the hooks 16 to be hooked in. Each hook 16 is hooked into the connecting column between the two push plates 20. The reverse motor reducer 15 pulls the push rod 18 and the push plate 20 to retract, which can pull the hooks 16 downward through the connecting column. Finally, when the guide rod slides to the end of the straight section of the slide groove 21, the hooks 16 are pressed tightly against the side wall of the fixed block 19 by the connecting column. At this time, the hooks 16 can be tightened, and the antenna array equipment is also tightly locked at the top of the platform 10. The tightened antenna array equipment will also press the sealing ring 12.

[0046] When it is necessary to lower the antenna array equipment, the locking mechanism 14 can be unlocked first. The electric lifting rod 23 can be started by starting the motor and reducer. The telescopic ends of the two electric lifting rods 23 pull the four rising pulleys 24, the connecting block 231 and the two descending pulleys 25 to descend. At this time, the descending pulleys 25 can pull the lifting base 6 and the platform 10 to descend through the recovery cable 28. The lifting cable 27 moves accordingly. During the descent, the rising pulleys 24 and the descending pulleys 25 can also be reversed by the lever to periodically drive the movable rod 32 to lubricate the lifting cable 27 and the recovery cable 28.

[0047] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.

[0048] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
