Detailed implementation manners

[0033] Referring to "embodiments" herein means that the specific features, structures, or characteristics described in connection with the embodiments can be included in at least one embodiment of the present application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0034] An embodiment of the present invention provides an intelligent automated factory tower crane, as Figures 1-14As shown in the figure, the tower crane of the intelligent automation factory includes: a tower body 1 and a balance arm 2 rotatably installed on the tower body 1; a connecting frame 3 slidably sleeved on the balance arm 2, an electric winch 4 is installed at the top of the connecting frame 3, and the electric winch 4 hoists goods through a steel wire rope 5; a connecting plate 42 provided at one end of the steel wire rope 5, and a hook 6 for hanging a goods rope and a hanging ring is installed at the bottom of the connecting plate 42; a group of connecting ropes 7 provided below the connecting frame 3 for preventing the connecting plate 42 from swaying, one end of each of the group of connecting ropes 7 is fixedly connected to the connecting plate 42, and the group of connecting ropes 7 are arranged in a triangle on the connecting plate 42; an intelligent control box 8 installed on the tower body 1; a support mechanism provided on the tower body 1 and the balance arm 2 for supporting the balance arm 2.

[0035] In this embodiment, the tower crane is composed of a tower body 1 and a balance arm 2 rotatably installed on the tower body 1, providing stable support and rotation function for hoisting operations. The electric winch 4 hoists goods through the steel wire rope 5 and the hook 6 to realize the lifting and lowering of the goods. A group of connecting ropes 7 are arranged in a triangle on the connecting plate 42. This design can effectively prevent the connecting plate 42 (and the hoisted goods) from swaying during the hoisting process, 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 balance arm 2 to realize the precise picking and placing of goods.

[0036] The intelligent control box 8 can collect diverse 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 means (such as Wi-Fi, Zigbee, LoRa, NB-IoT, etc.) to realize data storage and analysis. In the cloud or local server, the intelligent control box 8 uses built-in algorithms to analyze and process the collected data, obtain the working state and operation conditions of the equipment. According to the analysis results, the intelligent control box 8 can execute preset logical judgments or algorithm analyses to automatically adjust the working state of the equipment to achieve intelligent control.

[0037] In addition, during the operation of the tower crane, 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 realize the precise picking and placing of goods. By integrating advanced control algorithms and sensor technologies, the intelligent control box 8 can monitor and respond to various changes during the operation of the tower crane in real time to ensure the safety and stability of the operation.

[0038] Through the anti-sway connecting ropes 7 arranged in a triangle, the sway of the hoisted goods during the hoisting process is effectively reduced, enabling the goods to be placed more accurately at the designated position. At the same time, the anti-sway design not only improves the hoisting accuracy but also significantly enhances the safety of the tower crane hoisting operation and reduces the risk of safety accidents caused by the sway of the goods.

[0039] In a further preferred embodiment of the present invention, the support mechanism includes: a support ring 9 fixedly sleeved on the tower body 1; an adapter frame 10 fixedly installed at the bottom of the counterweight arm 2, and the adapter frame 10 is sleeved on the tower body 1; rollers 11 installed at the bottom of the adapter frame 10 for supporting the adapter frame 10, and the rollers 11 are in contact with the support ring 9.

[0040] In this embodiment, rollers 11 are installed at the bottom of the adapter 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 adapter frame 10 and the support ring 9 but also makes the counterweight arm 2 rotate more smoothly. Since the struts of the adapter frame 10 are inclined, this structure gives it good stability and load-bearing capacity. Through the mechanical principle of a triangular arrangement between the struts and the tower body 1, the adapter frame 10 can effectively assist in supporting the counterweight arm 2, ensuring the stability of the tower crane during operation. The stability of the support mechanism is greatly enhanced through the design of the adapter frame 10, enabling the tower crane to remain stable even when hoisting heavy goods. At the same time, the contact method between the rollers 11 and the support ring 9 reduces friction and wear, extends the service life of the tower crane, and reduces the maintenance cost.

[0041] In a further preferred embodiment of the present invention, a rotation adjustment mechanism for rotating and adjusting the counterweight arm 2 is provided on the tower body 1. The rotation adjustment mechanism includes: a mounting frame 12 fixedly installed on the tower body 1; a connecting gear 13 fixedly sleeved on the rotating shaft of the counterweight arm 2; a hydraulic cylinder 14 installed on the mounting frame 12; a connecting rack 15 fixedly installed on the output rod of the hydraulic cylinder 14 for driving the connecting gear 13 and the counterweight arm 2 to rotate, and the connecting rack 15 meshes with the connecting gear 13.

[0042] In this embodiment, when the intelligent control box 8 controls the hydraulic cylinder 14 to work, the telescoping of its output rod will drive the sliding of the connecting rack 15. When the connecting rack 15 slides, it will drive the meshing connecting gear 13 to rotate. Since the connecting gear 13 is fixedly connected to the rotating shaft of the counterweight arm 2, the rotation of the connecting gear 13 will drive the counterweight arm 2 to rotate together. By precisely controlling the output of the hydraulic cylinder 14, precise adjustment of the rotation angle of the counterweight arm 2 can be achieved;

[0043] Through the precise control of the hydraulic cylinder 14 and the connecting rack 15, fine adjustment of the rotation angle of the balance arm 2 can be achieved, thereby improving the handling accuracy of goods. At the same time, the power provided by the hydraulic cylinder 14 is stable and controllable, making the balance arm 2 more stable during rotation, reducing the safety risks caused by shaking. The precise rotation adjustment mechanism enables the tower crane to locate the specified position for goods handling more quickly and accurately, improving the overall operation efficiency.

[0044] In a further preferred embodiment of the present invention, a limit block 16 is fixedly installed at 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 stable movement of the connecting rack 15.

[0045] 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 deviation 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 meshing with the connecting gear 13 during movement, thus ensuring the accuracy and stability of the rotation of the balance arm 2. Through the design of the limit block 16, the connecting rack 15 moves more smoothly during movement, reducing errors caused by shaking or deviation, improving the operation accuracy of the tower crane, reducing the safety risks caused by the shaking of the connecting rack 15 through stable mobility, ensuring the safety of the tower crane during operation. At the same time, by reducing shaking and deviation, the limit block 16 also helps to extend the service life of the connecting rack 15 and the connecting gear 13, reducing the maintenance cost.

[0046] 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 winding and unwinding the connecting rope 7 is rotatably installed in the connecting box 18. A support wheel 20 for guiding the connecting rope 7 is fixedly installed on one side of the connecting box 18.

[0047] In this embodiment, when the electric winch 4 works, it drives the wire rope 5 to perform winding and unwinding operations. At the same time, the storage roller 19 also rotates synchronously to perform synchronous winding and unwinding operations on the connecting rope 7. This design ensures the synchronism of the wire rope 5 and the connecting rope 7 during the ascent or descent of the goods, thereby maintaining the stability of the goods. A support wheel 20 is fixedly installed on one side of the connection box 18 to guide 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 ascent or descent is ensured, and the safety risks caused by shaking or deviation are reduced. At the same time, the synchronous operation design of the storage roller 19 and the electric winch 4 makes the coordination between the various components of the tower crane stronger during operation, improving the overall operation efficiency. Through the guiding action of the support wheel 20, the friction and wear of the connecting rope 7 during winding and unwinding are reduced, which helps to extend the service life of the connecting rope 7 and the storage roller 19.

[0048] In a further preferred embodiment of the present invention, a first rotating rod 21 is rotatably installed at the bottom of the mounting plate 17. Conical gears 22 are fixedly sleeved on the rotating shafts of the first rotating rod 21 and the storage roller 19. The two conical gears 22 are meshed with each other. A second rotating rod 23 is rotatably installed at the top of the connection frame 3. Sprockets 24 are fixedly sleeved on both ends of the second rotating rod 23, the rotating shaft of the electric winch 4, and the first rotating rod 21. The multiple sprockets 24 are divided into two groups, and chains 25 are sleeved on both groups of sprockets 24.

[0049] In this embodiment, when the electric winch 4 works, its rotating shaft starts to rotate and drives the second rotating rod 23 and the first rotating rod 21 to rotate synchronously through the chain 25. Since conical gears 22 that are meshed with each other are fixedly sleeved on the rotating shafts of the first rotating rod 21 and the storage roller 19, the rotation of the first rotating rod 21 will further drive the storage roller 19 to rotate synchronously. In this way, while the electric winch 4 winds and unwinds the wire rope 5, the storage roller 19 also winds and unwinds the connecting rope 7 synchronously, realizing the synchronous operation of the two. Through the transmission design of the sprockets 24, the chains 25, and the conical gears 22, it is ensured that the rotating shaft of the electric winch 4 and the rotating shaft of the storage roller 19 can rotate precisely synchronously, thereby realizing the synchronous winding and unwinding operations of the wire rope 5 and the connecting rope 7.

[0050] In a further preferred embodiment of the present invention, a U-shaped groove is formed at the bottom of the balance arm 2. A connecting rod 26 is rotatably installed at the bottom inner wall of the connection frame 3. A driving gear 27 is fixedly sleeved at one end of the connecting rod 26. A driving rack 28 is fixedly installed at the top of the U-shaped groove. The driving rack 28 is meshed with the driving gear 27. A double-headed motor 29 for driving the driving gear 27 to rotate and driving the connection frame 3 to slide along the balance arm 2 is fixedly installed at the top inner wall of the connection frame 3. The output shaft of the double-headed motor 29 is fixedly connected to the connecting rod 26.

[0051] In this embodiment, the driving gear 27 meshes with the driving rack 28. This design enables the driving gear 27 to drive 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.

[0052] 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 driving gear 27 to rotate synchronously. Since the driving gear 27 meshes with the driving rack 28, the rotation of the driving 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 working range of the tower crane is significantly expanded, and it can more flexibly handle various complex scenarios and cargo handling requirements. The driving mode of the double-headed motor 29 makes the movement of the connecting frame 3 faster and more accurate, improving the overall working efficiency of the tower crane. The meshing action between the driving gear 27 and the driving rack 28 ensures the stability and accuracy of the connecting frame 3 during movement, reducing the safety risks caused by shaking or deviation.

[0053] In a further preferred embodiment of the present invention, connection grooves are formed on both sides of the balance arm 2, and guide wheels 30 are rotatably installed at the bottom of the connection grooves. One side of the inner wall of the connecting frame 3 is fixedly installed with a connecting block 31, and the connecting block 31 is in rotational contact with the guide wheel 30. The arrangement of the guide wheel 30 and the connecting block 31 is used to assist in supporting the connecting frame 3.

[0054] In this embodiment, when the connecting frame 3 moves along the balance 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 an additional supporting force 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 balance arm 2, enabling the connecting frame 3 to 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, reducing the safety risks caused by shaking or deviation. At the same time, the rolling action of the guide wheel 30 reduces the friction, making the movement of the connecting frame 3 on the balance arm 2 smoother and faster, improving the overall working efficiency of the tower crane.

[0055] In a further preferred embodiment of the present invention, a disc 32 is rotatably installed at the bottom of the inner wall of the connection box 18. A convex block 33 is fixedly installed on the top of the disc 32, and the convex block 33 is close to the edge of the disc 32. A guide frame 34 is movably sleeved on the convex block 33, and a guide cylinder 35 for guiding the connecting rope 7 is fixedly installed on the top of the guide frame 34.

[0056] In this embodiment, when the disc 32 rotates, the convex block 33 drives the guide frame 34 to perform a reciprocating motion in the left - right direction. At the same time, since the convex block 33 is close to the edge of the disc 32, when the disc 32 rotates, the convex block 33 also moves in the up - down direction within the guide frame 34. This compound motion enables the guide frame 34 to drive the guide cylinder 35 and the connecting rope 7 to move along a left - right trajectory, thereby achieving uniform winding of the connecting rope 7 on the storage roller 19.

[0057] By optimizing the winding method of the connecting rope 7, this embodiment improves the storage efficiency of the storage roller 19, ensures the stability and orderliness of the connecting rope 7 during storage. This helps to reduce chaos and safety hazards caused by uneven winding, and improves the overall operation efficiency and safety of the tower crane.

[0058] In a further preferred embodiment of the present invention, both ends of the guide cylinder 35 are arranged in a flared shape, and the guide cylinder 35 is used to evenly wind the connecting rope 7 on the storage roller 19.

[0059] In this embodiment, when the disc 32 rotates, the convex block 33 drives the guide frame 34 to move along a left - right trajectory, and the guide frame 34 guides the connecting rope 7 through the guide cylinder 35 at its top. Since both ends of the guide cylinder 35 are arranged in a flared shape, this design enables the connecting rope 7 to enter and leave the guide cylinder 35 more smoothly, reducing friction and resistance. At the same time, the flared 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 on the storage roller 19.

[0060] To further improve the use effect of this device, in addition to the above - mentioned solution, this solution also has the following embodiments:

[0061] 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.

[0062] In this embodiment, when the guide frame 34 is driven to move by the disc 32 and the convex block 33, the guide block 37 slides on the guide rod 36 accordingly. Since the guide rod 36 provides stable support and guidance, the moving trajectory and direction of the guide frame 34 are effectively controlled. Through the cooperation of the guide rod 36 and the guide block 37, the guide frame 34 can maintain stability during movement, avoiding uneven winding and safety hazards caused by shaking or deviation. At the same time, through the guiding action of the guide rod 36, it can ensure that the guide frame 34 moves along a predetermined trajectory and direction, thereby improving the winding accuracy of the connecting rope 7 on the storage roller 19.

[0063] In another embodiment of the present invention, a connecting mechanism is provided on the connecting box 18 for synchronously and simultaneously rotating the disc 32 and the storage roller 19. The connecting mechanism includes: a round rod 38 rotatably mounted at the bottom of the connecting box 18; a second bevel gear 39 fixedly sleeved on the round rod 38 and the rotating shaft of the disc 32, and the two second bevel gears 39 are meshed with each other; a second sprocket 40 fixedly sleeved on the round rod 38 and the first rotating rod 21 respectively, and a second chain 41 is sleeved on the two second sprockets 40.

[0064] In this embodiment, when the storage roller 19 rotates through the first rotating rod 21, the second sprocket 40 connected thereto will rotate accordingly. Since the second chain 41 connects the two second sprockets 40, the second sprocket 40 on the round rod 38 will also rotate synchronously. Furthermore, the rotation of the round rod 38 will drive the second bevel gear 39 connected thereto to rotate. Since the two second bevel gears 39 are meshed with each other, the second bevel gear 39 on the rotating shaft of the disc 32 will also rotate synchronously, thereby driving the disc 32 to rotate;

[0065] As the disc 32 rotates, the convex block 33 will drive the guide frame 34 to move. The guide frame 34 maintains a stable movement trajectory by sliding the guide block 37 on the guide rod 36. At the same time, the guide cylinder 35 at the top of the guide frame 34 will move accordingly, thereby guiding the connecting rope 7 to be evenly wound on the storage roller 19;

[0066] Through the cooperation of the second bevel gear 39, the second sprocket 40 and the second chain 41, the synchronous rotation of the disc 32 and the storage roller 19 is realized, ensuring that when the storage roller 19 rotates to store or release the connecting rope 7, the disc 32 can synchronously drive the guide frame 34 and the guide cylinder 35 to move. Through the design of synchronous rotation, the connecting rope 7 can be evenly and quickly wound while the storage roller 19 rotates, improving the winding efficiency.

[0067] 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. The self-locking mechanism includes: a fixed frame 43 fixedly installed on the top of the connecting plate 42; a first threaded rod 44 rotatably installed on the fixed frame 43; a first threaded cylinder 45 threadedly sleeved on the first threaded rod 44, and the first threaded cylinder 45 slidably penetrates through the connecting plate 42, and the bottom end of the first threaded cylinder 45 is adapted to the groove of the hook 6; a first driven rack 46 installed on the steel wire rope 5; a bracket 47 fixedly installed on the top of the fixed frame 43, and a first driven gear 48 is rotatably installed on one side of the bracket 47; two third bevel gears 49 respectively provided on the bracket 47 and the first driven gear 48, and the two third bevel gears 49 are meshed with each other, and the output rod of the third bevel gear 49 located on the bracket 47 is fixedly connected to the first threaded rod 44.

[0068] In this embodiment, when there is a load hanging on the hook 6, the electric winch 4 starts to wind up the steel wire rope 5. As the steel wire rope 5 gradually tightens, the driven rack one 46 installed on the steel wire rope 5 will also slide upward accordingly. The sliding of the driven rack one 46 will drive the driven gear one 48 meshing with it to rotate. The rotation of the driven gear one 48 will then drive the threaded rod one 44 to rotate through the transmission of the bevel gear three 49. Since the thread cylinder one 45 is threadedly sleeved on the threaded rod one 44, the rotation of the threaded rod one 44 will drive the thread cylinder one 45 to slide downward until its bottom end stably inserts into the groove of the hook 6, realizing the self-locking of the hook 6;

[0069] Through the design of the self-locking mechanism, it is ensured that when there is a load hanging on the hook 6, the hook 6 can be stably locked, preventing safety accidents caused by the loosening or falling off of the hook 6 during the transportation of the load, improving the safety of tower crane operation. At the same time, the self-locking mechanism is triggered by the tightened state of the steel wire rope 5, realizing automatic operation without manual intervention and improving the operation efficiency.

[0070] In another embodiment of the present invention, a return spring 50 and a guiding telescopic rod for the reset of the driven rack one 46 are fixedly installed at the top of the fixing frame 43. And the return spring 50 is sleeved on the guiding telescopic rod. The top ends of the return spring 50 and the guiding telescopic rod are both fixedly connected to the mounting plate of the driven rack one 46. A sliding rod 51 is slidably installed on the driven rack one 46, and the bottom end of the sliding rod 51 is fixedly connected to the top of the fixing frame 43.

[0071] In this embodiment, when the load is transported to the designated position and placed on the ground, the steel wire rope 5 is completely relaxed. Since there is sufficient room for the length of the steel wire rope 5 between the mounting plate of the driven rack one 46 and the connecting plate 42, when the steel wire rope 5 is relaxed, the return spring 50 and the guiding telescopic rod contract, driving the driven rack one 46 to slide smoothly downward along the sliding rod 51 for reset. Due to the limiting effect of the sliding rod 51, the driven rack one 46 can maintain a stable moving track during the reset process, avoiding shaking or deviation. As the driven rack one 46 resets, the thread cylinder one 45 connected to it will also rise away from the hook 6, thus releasing the self-locking state of the hook 6;

[0072] Through the combined use of the return spring 50 and the guiding telescopic rod, it is ensured that the driven rack one 46 can accurately reset when the steel wire rope 5 is relaxed, thus releasing the self-locking state of the hook 6, facilitating the unloading of the load and the repeated use of the hook 6. By setting the sliding rod 51, the moving direction of the driven rack one 46 is restricted, enabling it to maintain a stable and non-shaking moving track during the reset process, improving the stability of the reset process.

[0073] In another embodiment of the present invention, a carriage 52 is slidably provided on one side of the connection frame 3. A driven rack two 53 is fixedly installed on the top of the carriage 52. A driven gear two 54 is rotatably installed on one side of the connection frame 3. The driven gear two 54 meshes with the driven rack two 53. A threaded rod two 55 is rotatably installed on one side of the connection frame 3. Tapered gears four 72 are sleeved on both the threaded rod two 55 and the driven gear two 54. The two tapered gears four 72 mesh with each other. A threaded barrel two 56 is threadedly sleeved on the threaded rod two 55. A contact rod 57 is fixedly installed on one side of the threaded barrel two 56. A group of control switches 58 are installed on one side of the connection frame 3. A three-stage alarm 63 is installed on the tower body 1.

[0074] In this embodiment, when the connection frame 3 slides to one side on the counterweight arm 2, the carriage 52 will move accordingly. When the carriage 52 touches the baffle at one end of the counterweight arm 2, due to the continuous sliding of the connection frame 3, the carriage 52 will drive the driven rack two 53 to slide along one side of the connection frame 3. The sliding of the driven rack two 53 will drive the driven gear two 54 meshing with it to rotate. The rotation of the driven gear two 54 is transmitted through the tapered gears four 72 to drive the threaded rod two 55 to rotate. Since the threaded barrel two 56 is threadedly sleeved on the threaded rod two 55, the rotation of the threaded rod two 55 will drive the threaded barrel two 56 to rise. As the threaded barrel two 56 rises, the contact rod 57 will also rise accordingly and finally touch one of the independent switches in the control switch 58.

[0075] When the contact rod 57 touches the control switch 58, it will trigger the closing of the switch, thereby activating the three-stage alarm 63. Since the control switch 58 is composed of three independent switches, when the contact rod 57 touches different switches at different heights, three different levels of alarms can be realized for the three-stage alarm 63. This hierarchical alarm mechanism can more accurately reflect the proximity of the connection frame 3 to one end of the counterweight arm 2 and provide more clear warning information for the operator;

[0076] By adding components such as the carriage 52, the driven rack two 53, the driven gear two 54, etc., and the three-stage alarm 63, real-time monitoring and warning of the sliding process of the connection frame 3 on the counterweight arm 2 are realized, effectively preventing the connection frame 3 from colliding with one end of the counterweight arm 2, and improving the safety and stability of tower crane operation.

[0077] In another embodiment of the present invention, an adapter assembly 59 for guiding the threaded barrel two 56 and enabling it to move smoothly is provided on one side of the connection frame 3. The adapter assembly 59 is composed of an adapter rod and a slider. The adapter rod is fixedly installed on one side of the connection frame 3. The slider is slidably sleeved on the adapter rod and fixedly connected to the threaded barrel two 56.

[0078] In this embodiment, due to the combined use of the connecting rod and the slider, the second threaded cylinder 56 can be well guided and supported during the ascending or descending process. The connecting rod provides a stable moving path for the slider, and the slider transfers this stability to the second threaded cylinder 56 through the fixed connection with the second threaded cylinder 56. In this way, even in a complex external environment or when vibrations occur during the operation of the tower crane, the second threaded cylinder 56 can maintain a stable and non-shaky moving trajectory.

[0079] In another embodiment of the present invention, a fixed block 60 is fixedly installed on one side of the connecting frame 3. A fixed rod 61 is slidably arranged on the fixed block 60. One end of the fixed rod 61 is fixedly connected to one side of the carriage 52, and a connecting spring 62 for resetting the carriage 52 is sleeved on the fixed rod 61.

[0080] In this embodiment, when the carriage 52 contacts the baffle at one end of the counterweight arm 2, the fixed rod 61 will slide along the fixed block 60 and compress the connecting spring 62. The compression degree of the connecting spring 62 is proportional to the moving distance of the carriage 52, thereby realizing the buffering during the movement of the carriage 52 and the preparation for resetting after buffering.

[0081] When the connecting frame 3 resets, the connecting spring 62 will release the elastic potential energy stored therein, push the fixed rod 61 to slide reversely along the fixed block 60, and thus drive the carriage 52 to reset. In this way, the carriage 52 can smoothly return to its initial position to prepare for the next warning.

[0082] 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. An adapter box 65 is fixedly installed on the electric telescopic rod 71. A sponge roller 66 for applying lubricating oil to the driving rack 28 is rotatably installed in the adapter box 65. A dropper 67 is installed on one side of the liquid storage box 64. The dropper 67 is fixedly connected to the adapter box 65. Pulley wheels 68 are fixedly sleeved on the rotating shafts of the sponge roller 66 and the driving gear 27. A limiting wheel 69 is rotatably installed on one side of the inner wall of the connecting frame 3. A belt 70 is sleeved on the limiting wheel 69 and the two pulley wheels 68.

[0083] In this embodiment, the dropper 67 slowly drops a drop of lubricating oil into the connection box 65 at an interval of 10-15 minutes. The sponge roller 66 absorbs the dropped lubricating oil. When it is necessary to lubricate the driving rack 28 and the driving gear 27, first start the electric telescopic rod 71 to drive the connection box 65 to slide up to the vicinity of the driving rack 28 and the driving gear 27. At the same time, the sponge roller 66 releases the driving rack 28. At this time, due to the movement of the connection box 65, the pulley 68 will deflect. Through the setting of the limit wheel 69, the belt 70 remains in a tensioned state. Then start the double-headed motor 29 to drive the driving gear 27 to rotate. After that, through the transmission of the belt 70, the sponge roller 66 is driven to rotate at the same time. While the sponge roller 66 and the driving gear 27 are rotating, they slide along the driving rack 28, so as to evenly apply the lubricating oil absorbed on the sponge roller 66 to the teeth of the driving rack 28. By moving the driving gear 27 left and right along the driving rack 28, the uniform lubrication function of the driving gear 27 and the driving rack 28 can be realized. Through the combined use of the electric telescopic rod 71 and the belt 70, the automatic lubrication function of the driving rack 28 and the driving gear 27 is realized, and the lubrication operation can be completed without manual intervention, improving the lubrication efficiency. At the same time, through regular lubrication, the friction and wear between the driving rack 28 and the driving gear 27 can be reduced, thereby extending their service life.

[0084] In summary, compared with the related art, through the arrangement of the steel wire rope 5 and the connecting ropes 7 arranged in a triangle in this tower crane, the swing of the goods during hoisting can be effectively prevented, which is beneficial to improving the safety of the tower crane during hoisting.
