Description

Technical Field

[0001] This application relates to the field of intelligent articulated boom crane technology, and in particular to a load sensing control system for an intelligent articulated boom crane. Background Technology

[0002] A load-sensing control system for a knuckle boom crane is a device that adjusts the hydraulic system based on the load to provide better control and efficiency. It typically includes sensor components and other related control systems, such as a host computer, capable of sensing the crane's load status in real time and adjusting hydraulic system parameters, such as flow rate and pressure, accordingly to ensure stable, safe, and efficient operation of the crane. Sensors measure and monitor the crane's load in real time, including parameters such as weight and pressure. These sensors are usually installed in critical parts of the crane, such as the boom and wire ropes, to accurately acquire load information. The load information acquired by the sensors is transmitted to the control system, such as the host computer or controller. These systems process and analyze the signals to determine how to adjust the hydraulic system parameters to adapt to the current load condition.

[0003] In existing technologies, load sensors are not easy to disassemble and assemble quickly during operation and lack protective functions, which can easily lead to breakage under severe overload and cause safety accidents. To address these issues, we propose an intelligent load sensing control system for articulated boom cranes. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where load sensors are not easy to disassemble and assemble quickly during operation and lack protective functions, which can easily lead to breakage and safety accidents under severe overload. Therefore, this invention proposes an intelligent load sensing control system for articulated boom cranes.

[0005] The intelligent articulated boom crane load sensing control system provided in this application adopts the following technical solution:

[0006] The intelligent articulated boom crane load sensing control system includes:

[0007] Crane body;

[0008] The controller is mounted on the crane body.

[0009] The first lifting rope is connected to the main body of the crane.

[0010] The second lifting rope has a hook fixedly connected to one end. The first and second lifting ropes are connected to the same housing. A sealing plate is hinged to one side of the housing. A load sensor is installed inside the housing. The load sensor is equipped with a disassembly and assembly mechanism for quick disassembly and assembly. The load sensor, controller, and crane body are connected in sequence.

[0011] Furthermore, each of the two buffer plates has two symmetrical sliding grooves, and each of the four sliding grooves has a buffer column slidably installed in it. Each of the four buffer columns is fixedly connected to a damping spring, and one end of each of the four damping springs is fixedly connected to the inner wall of the four sliding grooves. When the load sensor breaks, the four damping springs can buffer the first and second suspension ropes.

[0012] Furthermore, two connecting plates are fixedly installed on the outside of the load sensor. Both connecting plates are slidably installed inside the housing. Each connecting plate has a sliding opening, and the same pull rod is slidably installed in the two sliding openings.

[0013] Furthermore, one end of each of the two levers is fixedly connected to the outside of the pull rod, and a compression spring is fitted on the outside of each of the two levers. The two ends of the compression spring are fixedly connected to the outside of the mounting base and the outside of the pull rod, respectively.

[0014] Furthermore, the disassembly and assembly mechanism includes two locking rods, and each of the inner walls of one side of the two locking slots has a sliding hole. The two locking rods are slidably installed in the two sliding holes respectively. Each of the two locking blocks has a slot on its outer side. The two locking rods cooperate with the two slots respectively. When the locking rods are engaged with the slots, the locking rods can position the locking blocks and the mounting base.

[0015] Furthermore, the load sensor is fixedly mounted with mounting bases at both the top and bottom, and each mounting base has a slot. Two locking blocks cooperate with the two slots respectively. When the locking blocks are engaged with the slots, the first or second suspension rope can be connected to the load sensor.

[0016] Furthermore, two buffer plates are slidably installed inside the housing, and the first and second lifting ropes are fixedly connected to the two buffer plates respectively. A locking block is fixedly installed at one end of each of the first and second lifting ropes.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] 1. When the pull rod is pulled, the pull rod drives the two locking rods to move horizontally. The two locking rods engage with the two slots respectively, thereby releasing the positioning of the two locking blocks and removing the two locking blocks. This allows for quick disassembly and assembly of the load sensor, facilitating maintenance and replacement.

[0019] 2. In the event of a load sensor breakage, this solution employs two buffer plates that work in conjunction with the housing to prevent the cargo from falling directly. Additionally, the four damping springs provide cushioning for the first and second lifting ropes, thus preventing accidents.

[0020] This invention allows for quick assembly and disassembly during use and provides protective functions to prevent breakage and safety accidents. It has a simple structure and is easy to use. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0026] Reference Figures 1-3 The intelligent articulated boom crane load sensing control system includes:

[0027] Crane body 1;

[0028] Controller 2 is installed on the crane body 1;

[0029] The first lifting rope 3 is connected to the crane body 1;

[0030] The second lifting rope 4 has a hook 5 fixedly connected to one end. The first lifting rope 3 and the second lifting rope 4 are connected to the same housing 6. A sealing plate 7 is hinged to one side of the housing 6. A load sensor 8 is installed inside the housing 6. The load sensor 8 is equipped with a disassembly and assembly mechanism for quick disassembly and assembly of the load sensor 8. The load sensor 8, the controller 2, and the crane body 1 are connected in sequence.

[0031] Reference Figure 2 and Figure 3 Each of the two buffer plates 12 has two symmetrical sliding grooves 13. Buffer posts 14 are slidably installed in each of the four sliding grooves 13. Damping springs 15 are fixedly connected to each of the four buffer posts 14. One end of each of the four damping springs 15 is fixedly connected to the inner wall of the four sliding grooves 13. When the load sensor 8 breaks, the four damping springs 15 can buffer the first suspension rope 3 and the second suspension rope 4. Two connecting plates 9 are fixedly installed on the outside of the load sensor 8. Both connecting plates 9 are slidably installed inside the housing 6. Each of the two connecting plates 9 has a sliding opening 19. A pull rod 17 is slidably installed in each of the two sliding openings 19. One end of each of the two locking rods 16 is fixedly connected to the outside of the pull rod 17. A compression spring 18 is sleeved on the outside of each of the two locking rods 16. The two ends of the compression spring 18 are fixedly connected to the outside of the mounting base 10 and the outside of the pull rod 17, respectively. The fixed connection and disassembly mechanism includes two locking rods 16. Each of the two locking slots has a sliding hole on one inner wall. The two locking rods 16 are slidably installed in the two sliding holes. Each of the two locking blocks 11 has a slot on its outer side. The two locking rods 16 engage with the two slots respectively. When the locking rods 16 engage with the slots, they can position the locking blocks 11 and the mounting base 10. Mounting bases 10 are fixedly installed on the top and bottom of the load sensor 8. Each mounting base 10 has a locking slot. The two locking blocks 11 engage with the two locking slots respectively. When the locking blocks 11 engage with the slots, the first lifting rope 3 or the second lifting rope 4 can be connected to the load sensor 8. Two buffer plates 12 are slidably installed inside the housing 6. The first lifting rope 3 and the second lifting rope 4 are fixedly connected to the two buffer plates 12 respectively. A locking block 11 is fixedly installed at one end of each of the first lifting rope 3 and the second lifting rope 4.

[0032] The implementation principle of the intelligent folding boom crane load sensing control system in this application embodiment is as follows: During use, the pull rod 17 can be moved horizontally, and the pull rod 17 drives the two locking rods 16 to move horizontally. When the two locking rods 16 are separated from the two slots respectively, the two locking blocks 11 can be driven, thereby allowing the load sensor 8 to be quickly disassembled and assembled for easy maintenance or replacement. When the crane body 1 is severely overloaded and the load sensor 8 breaks, the two buffer plates 12 cooperate with the housing 6 to prevent the hoisted goods from falling directly. At the same time, through the setting of four damping springs 15, the four damping springs 15 can respectively buffer the first hoisting rope 3 and the second hoisting rope 4, thereby effectively avoiding the occurrence of safety accidents and improving operational safety. Example

[0033] The difference between this embodiment and embodiment one is that: displacement sensors are installed on both connecting plates 9, and an alarm is installed on the crane body 1. The displacement sensors are connected to the alarm. The displacement sensors can monitor the distance between the two connecting plates 9 in real time. When the distance between the two connecting plates 9 exceeds a preset threshold, the displacement sensors send a command to the alarm, and the alarm sounds an alarm, thereby reminding the staff to stop the machine for maintenance in time.
