Description

Technical Field

[0001] This utility model relates to the technical field of hanger drive devices, and in particular to a device hanger drive device with overload protection. Background Technology

[0002] With its excellent safety performance, precise control capabilities, modular design, wide applicability, and economic benefits, the hanger drive unit has become an indispensable piece of equipment in modern industrial production. Hanger drive units are typically highly integrated, effectively utilizing limited space, and are particularly suitable for applications with strict installation space requirements. When used with servo motors, hydraulic or electric actuators, they can achieve high-precision position, speed, and torque control, making them suitable for systems requiring precise adjustment of attitude or position. They can operate reliably in harsh environments such as high temperature, high humidity, and high vibration.

[0003] However, commonly available hanger drive devices have significant drawbacks: First, they lack overload protection mechanisms. If the equipment encounters sudden overload or abnormal operating conditions during operation, the system lacks automatic power cut-off and alarm activation functions. This not only exacerbates the wear risk of core transmission components but may also lead to irreversible structural damage and even safety hazards. Second, the disassembly structure of the hook assembly is flawed, making disassembly inconvenient. This requires maintenance personnel to spend considerable time on complex disassembly operations and relies on special tools, severely hindering equipment failure repair efficiency, increasing subsequent maintenance costs, and failing to meet the actual needs of efficient operation and maintenance. Therefore, designing a hanger drive device with overload protection is essential. Utility Model Content

[0004] The purpose of this invention is to provide a device for driving a device with overload protection, in order to solve the defects of existing device drives that lack overload protection and have difficult hook disassembly.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a device hanger drive with overload protection, including a support base, a servo motor, a device housing, and an overload switch. A fixed hollow shaft is fixedly connected to the device housing. One end of a spring is fixedly connected to a groove inside the fixed hollow shaft. A sliding rod is fixedly connected to the other end of the spring. A second rotating shaft is rotatably connected to the sliding rod. A second pulley is fixedly connected to the second rotating shaft. An excitation rod is fixedly connected to the sliding rod. A first rotating shaft is rotatably connected inside the device housing. A first pulley is fixedly connected to the first rotating shaft. A fixed block is fixedly connected to the device housing. An overload switch is rotatably connected to the fixed block. A sleeve is fixedly connected to a groove inside the device housing. A threaded shaft is threadedly connected to the sleeve. The threaded shaft is sleeved in a through hole opened in the connecting block.

[0006] As a further technical solution of this utility model, the sliding rod is slidably connected in the groove of the fixed hollow shaft, and the excitation rod and the sliding rod are slidably connected in the groove of the equipment housing.

[0007] As a further technical solution of this utility model, a rotating device is fixedly connected to the threaded shaft, and the connecting block is slidably connected in the groove of the equipment box.

[0008] As a further technical solution of this utility model, a hook is fixedly connected to the connecting block.

[0009] As a further technical solution of this utility model, a support side frame is fixedly connected to the support base, a slide rail is fixedly connected to the support side frame, and a sliding device is slidably connected to the slide rail.

[0010] As a further technical solution of this utility model, the sliding device is equipped with an alarm light, a first connecting shaft is fixedly connected to the bottom of the sliding device, a second connecting shaft is fixedly connected to the first connecting shaft, and a device housing is fixedly connected to the second connecting shaft.

[0011] As a further technical solution of this utility model, a servo motor is fixedly connected to the sliding device, a third rotating shaft is fixedly connected to the output end of the servo motor, a gear is fixedly connected to the third rotating shaft, the gear is meshed with a tooth groove, and the tooth groove is fixedly connected to the slide rail.

[0012] This utility model provides a device for driving a lifting rack with overload protection. Its advantages are as follows: A servo motor drives a third rotating shaft to rotate, which in turn drives a gear to rotate, ultimately driving a sliding device to slide on a slide rail. Ropes pass through the first and second pulleys respectively. When the weight of the load exceeds a set value, the sliding rod and the second rotating shaft slide upwards, compressing the spring and causing the trigger rod to slide upwards, ultimately opening the overload switch, stopping the machine, and triggering an alarm. The system can automatically cut off power and activate the alarm function, reducing the risk of wear on core transmission components and preventing potential safety hazards. During disassembly, the rotating device is turned, causing the threaded shaft to rotate, which is then removed from the through hole of the connecting block. Finally, the connecting block and hook can be directly disassembled. Maintenance personnel do not need to spend a lot of time on complex disassembly operations or rely on special tools, significantly improving the efficiency of equipment fault repair and reducing subsequent maintenance costs, thus meeting the actual needs of efficient operation and maintenance.
