[0019] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0020] The embodiment of the present invention provides an intelligent automated factory tower crane, such as Figure 1-14As shown, the intelligent automated factory tower crane comprises: a tower body 1 and a balancing arm 2 rotatably mounted on the tower body 1; a connecting frame 3 slidably mounted on the balancing arm 2, an electric winch 4 being mounted on the top of the connecting frame 3, and the electric winch 4 hoists cargo through a steel wire rope 5; a connecting plate 42 disposed at one end of the steel wire rope 5, and a hook 6 for hanging cargo ropes and hanging rings being mounted at the bottom of the connecting plate 42; a group of connecting ropes 7 disposed below the connecting frame 3 for preventing the connecting plate 42 from swinging, one end of each group of the connecting ropes 7 being fixedly connected to the connecting plate 42, and a group of the connecting ropes 7 being arranged in a triangular shape on the connecting plate 42; an intelligent control box 8 mounted on the tower body 1; and a supporting mechanism disposed on the tower body 1 and the balancing arm 2 for supporting the balancing arm 2.

[0021] In this embodiment, the tower crane is composed of a tower body 1 and a balancing arm 2 rotatably mounted on the tower body 1, which provides stable support and rotation functions for the hoisting operation. The electric winch 4 hoists the cargo through the steel wire rope 5 and the hook 6 to achieve the lifting and lowering of the cargo. A group of connecting ropes 7 are arranged in a triangular shape on the connecting plate 42. This design can effectively prevent the connecting plate 42 (and the hoisted cargo) from swaying during the hoisting process, thereby improving the hoisting accuracy and safety. At the same time, the intelligent control box 8 installed on the tower body 1 can accurately control the operation of the electric winch 4, the sliding distance of the connecting frame 3, and the rotation angle of the balancing arm 2, thereby achieving accurate loading and unloading of the cargo. The smart control box 8 can collect diversified data of environmental parameters (such as temperature, humidity, etc.) and equipment status (such as switch status, operating parameters, etc.) in real time through built-in sensors or interfaces. These data are transmitted to the cloud or local server through wireless or wired methods (such as Wi-Fi, Zigbee, LoRa, NB-IoT, etc.) to realize data storage and analysis. In the cloud or local server, the smart control box 8 uses built-in algorithms to analyze and process the collected data to obtain the working status and operation status of the equipment. According to the analysis results, the smart control box 8 can execute preset logical judgments or algorithm analysis, automatically adjust the working status of the equipment, and realize intelligent control; In addition, during the tower crane operation, the intelligent control box 8 can accurately control the operation of the electric winch 4, the sliding distance of the connecting frame 3 and the rotation angle of the balance arm 2 to achieve accurate loading and unloading of goods. By integrating advanced control algorithms and sensor technology, the intelligent control box 8 can monitor and respond to various changes in the tower crane operation in real time to ensure the safety and stability of the operation. The anti-sway connecting rope 7 arranged in a triangular shape effectively reduces the swaying of the hoisted cargo during the lifting process, so that the cargo can be placed at the designated position more accurately. At the same time, the anti-sway design not only improves the lifting accuracy, but also significantly enhances the safety of the tower crane lifting operation and reduces the risk of safety accidents caused by the swaying of the cargo.

[0022] In a further preferred embodiment of the present invention, the supporting mechanism includes: a supporting ring 9 fixedly mounted on the tower body 1; a connecting frame 10 fixedly mounted on the bottom of the balancing arm 2, and the connecting frame 10 is mounted on the tower body 1; a roller 11 installed at the bottom of the connecting frame 10 for supporting the connecting frame 10, and the roller 11 is in contact with the supporting ring 9.

[0023] In this embodiment, rollers 11 are installed at the bottom of the connecting frame 10, and these rollers 11 are in contact with the support ring 9. The design of the rollers 11 not only reduces the friction between the connecting frame 10 and the support ring 9, but also makes the balance arm 2 more stable when rotating. Since the support rods of the connecting frame 10 are arranged in an inclined state, this structure makes it have good stability and load-bearing capacity. Through the mechanical principle of the triangular arrangement between the support rods and the tower body 1, the connecting frame 10 can effectively assist in supporting the balance arm 2 to ensure the stability of the tower crane during operation. The design of the connecting frame 10 greatly enhances the stability of the supporting mechanism, so that the tower crane can remain stable when hoisting heavy goods. At the same time, the contact between the rollers 11 and the support ring 9 reduces friction and wear, extends the service life of the tower crane, and reduces maintenance costs.

[0024] In a further preferred embodiment of the present invention, a rotation adjustment mechanism for rotationally adjusting the balance arm 2 is provided on the tower body 1, and the rotation adjustment mechanism includes: a mounting frame 12 fixedly mounted on the tower body 1; a connecting gear 13 fixedly sleeved on the rotating shaft of the balance arm 2; a hydraulic cylinder 14 mounted on the mounting frame 12; and a connecting rack 15 fixedly mounted on the output rod of the hydraulic cylinder 14 for driving the connecting gear 13 and the balance arm 2 to rotate, and the connecting rack 15 is meshed with the connecting gear 13.

[0025] In this embodiment, when the intelligent control box 8 controls the hydraulic cylinder 14 to work, the extension and retraction of its output rod will drive the sliding of the connecting rack 15. When the connecting rack 15 slides, it will drive the connecting gear 13 meshed with it to rotate. Since the connecting gear 13 is fixedly connected to the rotating shaft of the balancing arm 2, the rotation of the connecting gear 13 will drive the balancing arm 2 to rotate together. By accurately controlling the output of the hydraulic cylinder 14, the precise adjustment of the rotation angle of the balancing arm 2 can be achieved. Through the precise control of the hydraulic cylinder 14 and the connecting rack 15, the rotation angle of the balancing arm 2 can be fine-tuned, thereby improving the cargo handling accuracy. At the same time, the power provided by the hydraulic cylinder 14 is stable and controllable, making the balancing arm 2 more stable during rotation, reducing the safety risks caused by shaking, and the precise rotation adjustment mechanism enables the tower crane to be positioned at the designated position for cargo handling more quickly and accurately, thereby improving the overall operating efficiency.

[0026] In a further preferred embodiment of the present invention, a limit block 16 is fixedly installed on the top of the mounting frame 12, the limit block 16 is slidably connected to the connecting rack 15, and the limit block 16 is used to guide the connecting rack 15 to move smoothly.

[0027] In this embodiment, the limit block 16 is slidably connected to the connecting rack 15. This design ensures that the connecting rack 15 always slides smoothly along a predetermined path during movement, avoiding errors caused by offset or shaking. The limit block 16 not only provides physical support for the connecting rack 15, but also plays a guiding role. It ensures that the connecting rack 15 can maintain precise engagement with the connecting gear 13 during movement, thereby ensuring the accuracy and stability of the rotation of the balance arm 2. The design of the limit block 16 makes the connecting rack 15 more stable during movement, reduces errors caused by shaking or offset, and improves the operating accuracy of the tower crane. The safety risks caused by the shaking of the connecting rack 15 are reduced through stable mobility, ensuring the safety of the tower crane during operation. At the same time, by reducing shaking and offset, the limit block 16 also helps to extend the service life of the connecting rack 15 and the connecting gear 13, reducing maintenance costs.

[0028] In a further preferred embodiment of the present invention, a mounting plate 17 is fixedly installed at the bottom of the connecting frame 3, a connecting box 18 is fixedly installed at the bottom of the mounting plate 17, a storage roller 19 for reeling in and out the connecting rope 7 is rotatably installed in the connecting box 18, and a support wheel 20 for guiding the connecting rope 7 is fixedly installed on one side of the connecting box 18.

[0029] In this embodiment, when the electric winch 4 is working, it will drive the wire rope 5 to perform winding and unwinding operations, and the take-up roller 19 will also rotate synchronously to perform synchronous winding and unwinding operations on the connecting rope 7. This design ensures the synchronization of the wire rope 5 and the connecting rope 7 during the rising or falling of the goods, thereby maintaining the stability of the goods. A support wheel 20 is fixedly installed on one side of the connecting box 18 for guiding the connecting rope 7. By realizing the synchronous winding and unwinding operations of the wire rope 5 and the connecting rope 7, the stability of the goods during the rising or falling process is ensured, and the safety risks caused by shaking or deviation are reduced. At the same time, the synchronous operation design of the take-up roller 19 and the electric winch 4 makes the coordination between the various components of the tower crane during operation stronger, thereby improving the overall operation efficiency. Through the guiding effect of the support wheel 20, the friction and wear of the connecting rope 7 during the winding and unwinding process are reduced, which helps to extend the service life of the connecting rope 7 and the take-up roller 19.

[0030] In a further preferred embodiment of the present invention, a rotating rod 21 is rotatably installed at the bottom of the mounting plate 17, and a bevel gear 22 is fixedly sleeved on the rotating shafts of the rotating rod 21 and the storage roller 19, and the two bevel gears 22 are meshed with each other, and a rotating rod 23 is rotatably installed on the top of the connecting frame 3, and a sprocket 24 is fixedly sleeved on both ends of the rotating rod 23, the rotating shaft of the electric winch 4 and the rotating rod 21, and the multiple sprockets 24 are divided into two groups, and the two groups of sprockets 24 are both sleeved with a chain 25.

[0031] In this embodiment, when the electric winch 4 is working, its rotating shaft starts to rotate, and drives the rotating rod 23 and the rotating rod 21 to rotate synchronously through the chain 25. Since the rotating shafts of the rotating rod 21 and the taking-up roller 19 are fixedly sleeved with meshing bevel gears 22, the rotation of the rotating rod 21 will further drive the taking-up roller 19 to rotate synchronously. In this way, when the electric winch 4 reels in and unwinds the wire rope 5, the taking-up roller 19 will also synchronously rewind and unwind the connecting rope 7, thereby realizing the synchronous operation of the two. The transmission design of the sprocket 24, the chain 25 and the bevel gear 22 ensures that the rotating shaft of the electric winch 4 and the rotating shaft of the taking-up roller 19 can rotate accurately and synchronously, thereby realizing the synchronous winding and unwinding operation of the wire rope 5 and the connecting rope 7.

[0032] In a further preferred embodiment of the present invention, a U-shaped groove is provided at the bottom of the balancing arm 2, a connecting rod 26 is rotatably installed at the bottom of the inner wall of the connecting frame 3, a driving gear 27 is fixedly sleeved on one end of the connecting rod 26, a driving rack 28 is fixedly installed on the top of the U-shaped groove, the driving rack 28 is meshed with the driving gear 27, and a double-headed motor 29 is fixedly installed on the top of the inner wall of the connecting frame 3 for driving the driving gear 27 to rotate and drive the connecting frame 3 to slide along the balancing arm 2, and the output shaft of the double-headed motor 29 is fixedly connected to the connecting rod 26.

[0033] In this embodiment, the driving gear 27 is meshed with the driving rack 28. This design enables the connecting frame 3 to move left and right along the balance arm 2 through the meshing action with the driving rack 28 when the driving gear 27 rotates. When the intelligent control box 8 controls the double-headed motor 29 to work, its output shaft will drive the connecting rod 26 and the active gear 27 to rotate synchronously. Since the active gear 27 is meshed with the active rack 28, the rotation of the active gear 27 will further drive the connecting frame 3 to move left and right along the U-shaped groove of the balance arm 2, thereby realizing the precise movement of the connecting frame 3. By realizing the left and right movement of the connecting frame 3 along the balance arm 2, the operating range of the tower crane is significantly expanded, and it can more flexibly cope with various complex scenes and cargo handling needs. The driving mode of the double-headed motor 29 makes the movement of the connecting frame 3 faster and more accurate, thereby improving the overall operating efficiency of the tower crane. The meshing action of the active gear 27 and the active rack 28 ensures the stability and accuracy of the connecting frame 3 during movement, and reduces the safety risks caused by shaking or deviation.

[0034] In a further preferred embodiment of the present invention, connecting grooves are opened on both sides of the balance arm 2, and a guide wheel 30 is rotatably installed at the bottom of the connecting groove. A connecting block 31 is fixedly installed on one side of the inner wall of the connecting frame 3, and the connecting block 31 is in rotational contact with the guide wheel 30. The setting of the guide wheel 30 and the connecting block 31 is used to auxiliary support the connecting frame 3.

[0035] In this embodiment, when the connecting frame 3 moves along the balancing arm 2, the connecting block 31 will move synchronously and slide along the wheel surface of the guide wheel 30. The contact design between the guide wheel 30 and the connecting block 31 not only provides additional support for the connecting frame 3, but also ensures the smoothness of the connecting frame 3 during movement. The rolling action of the guide wheel 30 reduces the friction between the connecting block 31 and the balancing arm 2, so that the connecting frame 3 can move more smoothly and quickly. The contact design between the guide wheel 30 and the connecting block 31 enhances the stability of the connecting frame 3 during movement, reduces the safety risks caused by shaking or deviation, and at the same time, the rolling action of the guide wheel 30 reduces friction, so that the movement of the connecting frame 3 on the balancing arm 2 is smoother and faster, thereby improving the overall operating efficiency of the tower crane.

[0036] In a further preferred embodiment of the present invention, a disc 32 is rotatably mounted on the bottom of the inner wall of the connecting box 18, a protrusion 33 is fixedly mounted on the top of the disc 32, and the protrusion 33 is close to the edge of the disc 32, a guide frame 34 is movably sleeved on the protrusion 33, and a guide cylinder 35 for guiding the connecting rope 7 is fixedly mounted on the top of the guide frame 34.

[0037] In this embodiment, when the disc 32 rotates, the protrusion 33 drives the guide frame 34 to reciprocate in the left and right directions. At the same time, since the protrusion 33 is close to the edge of the disc 32, when the disc 32 rotates, the protrusion 33 also moves in the up and down directions inside the guide frame 34. This composite movement enables the guide frame 34 to drive the guide cylinder 35 and the connecting rope 7 to move in the left and right tracks, thereby achieving uniform winding of the connecting rope 7 on the receiving roller 19. By optimizing the winding method of the connecting rope 7, this embodiment improves the storage efficiency of the storage roller 19 and ensures the stability and orderliness of the connecting rope 7 during the storage process, which helps to reduce confusion and safety hazards caused by uneven winding and improves the overall operating efficiency and safety of the tower crane.

[0038] In a further preferred embodiment of the present invention, both ends of the guide cylinder 35 are arranged in a trumpet shape, and the guide cylinder 35 is used to evenly wind the connecting rope 7 around the storage roller 19.

[0039] In this embodiment, when the disc 32 rotates, the protrusion 33 drives the guide frame 34 to move in a left and right trajectory, and the guide frame 34 guides the connecting rope 7 through the guide cylinder 35 on its top. Since both ends of the guide cylinder 35 are arranged in a trumpet shape, this design allows the connecting rope 7 to enter and leave the guide cylinder 35 more smoothly, reducing friction and resistance. At the same time, the trumpet-shaped design also helps to maintain the tension and direction of the connecting rope 7 during the winding process, ensuring that it can be evenly and tightly wound around the storage roller 19.

[0040] In order to further improve the use effect of the device, in addition to the above scheme, this scheme also has the following embodiments: In another embodiment of the present invention, a guide rod 36 is fixedly installed in the connection box 18 , a guide block 37 is slidably sleeved on the guide rod 36 , and the guide block 37 is fixedly connected to the guide frame 34 .

[0041] In this embodiment, when the guide frame 34 is moved by the disk 32 and the protrusion 33, the guide block 37 will slide on the guide rod 36. Since the guide rod 36 provides stable support and guiding functions, the movement trajectory and direction of the guide frame 34 are effectively controlled. The cooperation between the guide rod 36 and the guide block 37 allows the guide frame 34 to remain stable during the movement, avoiding uneven winding and safety hazards caused by shaking or deviation. At the same time, the guiding function of the guide rod 36 can ensure that the guide frame 34 moves according to the predetermined trajectory and direction, thereby improving the winding accuracy of the connecting rope 7 on the storage roller 19.

[0042] In another embodiment of the present invention, the connecting box 18 is provided with a connecting mechanism for synchronously rotating the disc 32 and the receiving roller 19, and the connecting mechanism includes: a round rod 38 rotatably installed at the bottom of the connecting box 18; a bevel gear 2 39 fixedly mounted on the round rod 38 and the rotating shaft of the disc 32, and the two bevel gears 2 39 are meshed with each other; and a sprocket 2 40 fixedly mounted on the round rod 38 and the rotating rod 1 21, respectively, and a chain 2 41 is mounted on the two sprockets 2 40.

[0043] In this embodiment, when the storage roller 19 rotates through the rotating rod 1 21, the sprocket 2 40 connected thereto will rotate accordingly. Since the chain 2 41 connects the two sprockets 40, the sprocket 2 40 on the round rod 38 will also rotate synchronously. Furthermore, the rotation of the round rod 38 will drive the bevel gear 2 39 connected thereto to rotate. Since the two bevel gears 2 39 are meshed, the bevel gear 2 39 on the rotating shaft of the disc 32 will also rotate synchronously, thereby driving the disc 32 to rotate. As the disc 32 rotates, the protrusion 33 drives the guide frame 34 to move, and the guide frame 34 maintains a stable moving track by sliding the guide block 37 on the guide rod 36. At the same time, the guide cylinder 35 on the top of the guide frame 34 moves accordingly, thereby guiding the connecting rope 7 to be evenly wound around the storage roller 19; Through the cooperation of bevel gear 2 39, sprocket 2 40 and chain 2 41, synchronous rotation of disc 32 and storage roller 19 is achieved, ensuring that when the storage roller 19 rotates to store or release the connecting rope 7, disc 32 can synchronously drive the guide frame 34 and guide cylinder 35 to move. The synchronous rotation design allows the connecting rope 7 to be evenly and quickly wound while the storage roller 19 rotates, thereby improving the winding efficiency.

[0044] In another embodiment of the present invention, a self-locking mechanism for locking the hook 6 is provided on the top of the connecting plate 42, and the self-locking mechanism includes: a fixing frame 43 fixedly mounted on the top of the connecting plate 42; a threaded rod 44 rotatably mounted on the fixing frame 43; a threaded barrel 45 threadedly sleeved on the threaded rod 44, the threaded barrel 45 slides through the connecting plate 42, and the bottom end of the threaded barrel 45 is matched with the groove of the hook 6; a driven rack 46 installed on the wire rope 5; a bracket 47 fixedly mounted on the top of the fixing frame 43, a driven gear 48 rotatably mounted on one side of the bracket 47; two bevel gears 49 respectively provided on the bracket 47 and the driven gear 48, the two bevel gears 49 are meshed with each other, and the output rod of the bevel gear 49 located on the bracket 47 is fixedly connected to the threaded rod 44.

[0045] In this embodiment, when the hook 6 is hung with goods, the electric winch 4 starts to reel in the wire rope 5. As the wire rope 5 is gradually tightened, the driven rack 46 installed on the wire rope 5 will slide upwards. The sliding of the driven rack 46 will drive the driven gear 48 meshing with it to rotate. The rotation of the driven gear 48 will then drive the threaded rod 44 to rotate through the transmission of the bevel gear 3 49. Since the threaded barrel 45 is threadedly sleeved on the threaded rod 44, the rotation of the threaded rod 44 will drive the threaded barrel 45 to slide downwards until its bottom end is stably inserted into the groove of the hook 6, thereby realizing the self-locking of the hook 6. The design of the self-locking mechanism ensures that when there is cargo hanging on the hook 6, the hook 6 can be stably locked, preventing safety accidents caused by the hook 6 loosening or falling off during transportation, thereby improving the safety of tower crane operation. At the same time, the self-locking mechanism is triggered by the tensioned state of the wire rope 5, realizing automatic operation without manual intervention, thereby improving operation efficiency.

[0046] In another embodiment of the present invention, a reset spring 50 and a guide telescopic rod for resetting the driven rack 46 are fixedly installed on the top of the fixed frame 43, and the reset spring 50 is sleeved on the guide telescopic rod, and the top ends of the reset spring 50 and the guide telescopic rod are fixedly connected to the mounting plate of the driven rack 46, and a sliding rod 51 is slidably installed on the driven rack 46, and the bottom end of the sliding rod 51 is fixedly connected to the top of the fixed frame 43.

[0047] In this embodiment, when the goods are transported to the designated location and placed on the ground, the steel wire rope 5 is completely relaxed. Since the length of the steel wire rope 5 between the mounting plate of the driven rack 46 and the connecting plate 42 has sufficient room, when the steel wire rope 5 is relaxed, the return spring 50 and the guide telescopic rod contract, driving the driven rack 46 to slide down smoothly along the slide bar 51 to return to its original position. Due to the limiting effect of the slide bar 51, the driven rack 46 can maintain a stable moving trajectory during the return process to avoid shaking or deviation. As the driven rack 46 is returned to its original position, the threaded barrel 45 connected thereto will also rise away from the hook 6, thereby releasing the self-locking state of the hook 6. The cooperation of the reset spring 50 and the guide telescopic rod ensures that the driven rack 46 can be accurately reset when the wire rope 5 is relaxed, thereby releasing the self-locking state of the hook 6, facilitating the unloading of goods and the reuse of the hook 6. The setting of the slide bar 51 limits the moving direction of the driven rack 46, so that it can maintain a smooth and shaking moving trajectory during the reset process, thereby improving the stability of the reset process.

[0048] In another embodiment of the present invention, a slide 52 is slidably provided on one side of the connecting frame 3, a driven rack 2 53 is fixedly installed on the top of the slide 52, a driven gear 2 54 is rotatably installed on one side of the connecting frame 3, the driven gear 2 54 is meshed with the driven rack 2 53, a threaded rod 2 55 is rotatably installed on one side of the connecting frame 3, both the threaded rod 2 55 and the driven gear 2 54 are provided with a bevel gear 4 72, the two bevel gears 4 72 are meshed with each other, a threaded tube 2 56 is threadedly provided on the threaded rod 2 55, a touch rod 57 is fixedly installed on one side of the threaded tube 2 56, a group of control switches 58 are installed on one side of the connecting frame 3, and a three-level alarm 63 is installed on the tower body 1.

[0049] In this embodiment, when the connecting frame 3 slides to one side on the balancing arm 2, the slide 52 will move accordingly. When the slide 52 contacts the baffle at one end of the balancing arm 2, due to the continued sliding of the connecting frame 3, the slide 52 will drive the driven rack 2 53 to slide along one side of the connecting frame 3. The sliding of the driven rack 2 53 will drive the driven gear 2 54 meshing therewith to rotate. The rotation of the driven gear 2 54 is driven by the bevel gear 4 72 to drive the threaded rod 2 55 to rotate. Since the threaded barrel 2 56 is threadedly sleeved on the threaded rod 2 55, the rotation of the threaded rod 2 55 will drive the threaded barrel 2 56 to rise. As the threaded barrel 2 56 rises, the touch rod 57 will also rise accordingly and finally contact an independent switch in the control switch 58.

[0050] When the touch rod 57 contacts the control switch 58, the switch will be closed, thereby activating the three-level alarm 63. Since the control switch 58 is composed of three independent switches, when the touch rod 57 contacts different switches at different heights, the three-level alarm 63 can be alarmed in three different degrees. This hierarchical alarm mechanism can more accurately reflect the proximity between the connecting frame 3 and one end of the balance arm 2, and provide clearer early warning information for the operator. By adding components such as the slide 52, the driven rack 2 53, the driven gear 2 54, and the three-level alarm 63, real-time monitoring and early warning of the sliding process of the connecting frame 3 on the balance arm 2 are achieved, effectively preventing the connecting frame 3 from colliding with one end of the balance arm 2, thereby improving the safety and stability of the tower crane operation.

[0051] In another embodiment of the present invention, a connecting component 59 for guiding the threaded barrel 2 56 and enabling it to move smoothly is provided on one side of the connecting frame 3. The connecting component 59 is composed of a connecting rod and a slider. The connecting rod is fixedly mounted on one side of the connecting frame 3, and the slider is slidably mounted on the connecting rod and fixedly connected to the threaded barrel 2 56.

[0052] In this embodiment, due to the coordinated use of the connecting rod and the slider, the threaded barrel 56 can be well guided and supported during the rising or falling process. The connecting rod provides a stable moving path for the slider, and the slider transmits this stability to the threaded barrel 56 through a fixed connection with the threaded barrel 56. In this way, even when the external environment is complex or vibrations are generated during the operation of the tower crane, the threaded barrel 56 can maintain a smooth and shaking movement trajectory.

[0053] In another embodiment of the present invention, a fixing block 60 is fixedly installed on one side of the connecting frame 3, a fixing rod 61 is slidably provided on the fixing block 60, one end of the fixing rod 61 is fixedly connected to one side of the slide 52, and a connecting spring 62 for resetting the slide 52 is sleeved on the fixing rod 61.

[0054] In this embodiment, when the slide 52 contacts the baffle at one end of the balance arm 2, the fixed rod 61 will slide along the fixed block 60 and compress the connecting spring 62. The degree of compression of the connecting spring 62 is proportional to the distance moved by the slide 52, thereby achieving buffering of the movement process of the slide 52 and preparation for reset after buffering.

[0055] When the connecting frame 3 is reset, the connecting spring 62 releases its stored elastic potential energy, pushing the fixing rod 61 to slide in the opposite direction along the fixing block 60, thereby driving the slide 52 to reset. In this way, the slide 52 can smoothly return to its initial position and prepare for the next warning.

[0056] In another embodiment of the present invention, a liquid storage box 64 for storing lubricating oil and an electric telescopic rod 71 are installed in the connecting frame 3, a connecting box 65 is fixedly installed on the electric telescopic rod 71, a sponge roller 66 for applying lubricating oil to the active rack 28 is rotatably installed in the connecting box 65, a dropper 67 is installed on one side of the liquid storage box 64, the dropper 67 is fixedly connected to the connecting box 65, a pulley 68 is fixedly sleeved on the rotating shaft of the sponge roller 66 and the active gear 27, a limiting wheel 69 is rotatably installed on one side of the inner wall of the connecting frame 3, and a belt 70 is sleeved on the limiting wheel 69 and the two pulleys 68.

[0057] In this embodiment, the dropper 67 slowly drips a drop of lubricating oil into the adapter box 65 at an interval of 10-15 minutes, and the sponge roller 66 absorbs the dripping lubricating oil. When the active rack 28 and the active gear 27 need to be lubricated, the electric telescopic rod 71 is first started to drive the adapter box 65 to slide up to the vicinity of the active rack 28 and the active gear 27. At the same time, the sponge roller 66 releases the active rack 28. At this time, due to the movement of the adapter box 65, the pulley 68 will deflect. Through the setting of the limit wheel 69, the belt 70 is still kept in a tensioned state, and then the double-headed motor 29 is started to drive the double-headed motor 29 to drive the active gear 27 to rotate. Then, through the transmission effect of the belt 70, The sponge roller 66 is driven to rotate, and the sponge roller 66 and the active gear 27 slide along the active rack 28 while rotating, so that the lubricating oil absorbed by the sponge roller 66 is evenly applied to the teeth of the active rack 28. The active gear 27 moves left and right along the active rack 28, so that the active gear 27 and the active rack 28 can be evenly lubricated. The electric telescopic rod 71 and the belt 70 are used in conjunction with each other to realize the automatic lubrication function of the active rack 28 and the active gear 27. The lubrication operation can be completed without manual intervention, thereby improving the lubrication efficiency. At the same time, regular lubrication can reduce the friction and wear between the active rack 28 and the active gear 27, thereby extending their service life.

[0058] In summary, compared with the related art, the tower crane can effectively prevent the cargo from swinging when it is hoisted by means of the steel wire rope 5 and the connecting ropes 7 arranged in a triangle, which is beneficial to improving the safety of the tower crane hoisting operation.
