Description

Technical Field

[0001] This utility model relates to the field of cable production and processing, and in particular to an electrically driven lifting device for an inverted tray material preparation platform. Background Technology

[0002] The inverted tray electrically driven material preparation platform lifting device is a device used in the production of cables and other similar products. Powered by electricity, it controls the height of the inverted tray material preparation platform. This device typically consists of a motor, a transmission mechanism, and a lifting platform panel. The motor drives the transmission mechanism, converting the motor's rotational motion into the vertical linear motion of the lifting platform, thus achieving the lifting function of the material preparation platform. It can precisely adjust the height of the material preparation platform according to production needs, facilitating the placement and retrieval of materials, helping to improve production efficiency, enhance material placement accuracy, and improve the stability and safety of equipment operation. It also better adapts to different production environments and spatial layout requirements.

[0003] Most existing material preparation platform lifting devices adopt a fixed transmission ratio design with a fixed lead screw pitch. The lifting speed cannot be dynamically adjusted according to the load and stroke, and the positioning accuracy is also poor, resulting in long loading and unloading times and affecting the overall production efficiency. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide an electrically driven lifting device for an inverted tray material preparation platform, so as to further improve the overall production efficiency of the device.

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

A secondary pulley is fixedly mounted on the top of the first bearing. A belt is engaged with the outer side of the secondary pulley. A main pulley is engaged with the inner side of the belt. A second bearing is fixedly mounted on the bottom end of the main pulley. The second bearing is rotatably connected to the mounting base. A fixing frame is fixedly mounted on one side of the mounting base. A motor is fixedly mounted on the inner side of the fixing frame. The output end of the motor is fixedly connected to the second bearing.

[0007] Preferably, a fixed seat is fixedly provided on the inner side of the auxiliary pulley, the fixed seat passes through the first shaft seat and extends to the outer side, a lead screw is threadedly connected to the inner side of the fixed seat, the lead screw passes through the fixed seat and extends to the outer side, a fixed shell is rotatably provided at the end of the lead screw extending to the outer side, and a horizontal plate is fixedly provided at the bottom of the fixed shell.

[0008] Preferably, two hydraulic cylinders are fixedly provided on the top of the mounting base, and a platform is provided on the top of the mounting base. The output ends of the two hydraulic cylinders are fixedly connected to the platform. Multiple hollow slide tubes are provided through the inner side of the mounting base, and the multiple hollow slide tubes are respectively arranged at the four corners of the mounting base.

[0009] Preferably, a fixing rod is slidably provided on the inner side of the hollow slide tube, the bottom end of the fixing rod is fixedly connected to the horizontal plate, the top end of the fixing rod is fixedly connected to the platform, and two sliding grooves are formed on the surface of the mounting base.

[0011] Preferably, the top end of the lead screw is provided with a fixed shell, the fixed shell is fixedly connected to the platform, and a baffle is fixedly provided on the top of the platform.

[0012] This utility model has the following beneficial effects:

[0013] 1. Dynamic adjustment of stroke: The device adopts a segmented variable pitch lead screw. The low load section uses a large pitch for rapid lifting and lowering, while the high load section switches to a small pitch for high torque output. The smooth transition is achieved through the gradual change of pitch on the lead screw surface, combined with the precise control of the servo motor, balancing efficiency and power.

[0014] II. Overload Protection and Locking of the Device: When the device reaches the predetermined height, the motor shuts off, and the fixed base stops rotating. Since the lead screw and the fixed base are connected by threads, the device is fixed and will not descend, thus playing a locking role. At the same time, if the device is carrying an excessively heavy object, the hydraulic cylinder can be used to push the platform upward to bear part of the load and reduce damage to the device.

[0015] 3. Precise Positioning: The device uses a synchronous belt and a motor to drive the fixed base to rotate. Since the fixed base is threadedly connected to the lead screw, the lead screw moves up or down when the fixed base rotates, adjusting the height. By using an electric slide rail installed at the bottom of the mounting base, the left and right movement of the device can be controlled, thereby achieving a precise positioning effect.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] First embodiment

[0023] according to Figures 1 to 2 As shown, an electrically driven lifting device for an inverted tray material preparation platform includes a mounting base. A first bearing is rotatably provided on the inner side of the mounting base. A secondary pulley is fixedly provided on the top of the first bearing. A belt is engaged on the outer side of the secondary pulley. A main pulley is engaged on the inner side of the belt. A second bearing is fixedly provided at the bottom end of the main pulley. The second bearing is rotatably connected to the mounting base. A fixing frame is fixedly provided on one side of the mounting base. A motor is fixedly provided on the inner side of the fixing frame. The output end of the motor is fixedly connected to the second bearing.

[0024] The basic framework is mainly composed of the mounting base 1, a core component, on which multiple key components are mounted to achieve functions such as lifting, raising and lowering, and stable operation.

[0025] Mounting base 1, as the main body of the entire device, provides a solid and orderly foundation space for the installation of various components. Its internal design is meticulous, possessing sufficient strength and stability to withstand various forces and vibrations generated during device operation. Inside mounting base 1, a first shaft seat 2 is cleverly rotatably mounted, providing support and guidance for the rotation of subsequent components.

[0026] A secondary pulley 3 is securely fixed to the top of the first bearing seat 2. The secondary pulley 3 is circular, and its outer surface is specially treated to tightly mesh with the belt 4. The inner side of the belt 4 also precisely meshes with the main pulley 5. The main pulley 5 is located inside the belt 4, and a second bearing seat 6 is fixed to its bottom end. The second bearing seat 6 is rotatably connected to the mounting base 1, ensuring that the main pulley 5 can rotate stably within the mounting base 1.

[0027] A mounting bracket 7 is fixedly installed on one side of the mounting base 1, providing a stable support for the installation of the motor 8. The motor 8 is fixedly installed inside the mounting bracket 7. The motor 8 serves as the power source for the entire device, and its output end is fixedly connected to the second shaft seat 6. When the motor 8 starts, its powerful force is transmitted to the second shaft seat 6 through its output end, thereby driving the main pulley 5 to rotate.

[0028] During device operation, motor 8 starts, driving main pulley 5 to rotate via second shaft seat 6. The rotation of main pulley 5 drives auxiliary pulley 3 to rotate synchronously via belt 4. The rotation of auxiliary pulley 3, in turn, causes the connected fixed seat 9 to rotate. Fixed seat 9 has an internal threaded structure, threadedly connected to lead screw 10. Due to this special connection method, when fixed seat 9 rotates, lead screw 10 moves upward or downward.

[0029] To achieve efficient operation under different loads, the lead screw 10 employs a unique design. In the low-load range, the lead screw 10 uses a large pitch design. At this time, the motor 8 drives the fixed base 9 to rotate rapidly, enabling the lead screw 10 to rise and fall quickly, thus rapidly raising and lowering the material preparation table, significantly reducing adjustment time and improving work efficiency. When entering the high-load range, the lead screw 10 cleverly switches to a small pitch. At this time, the motor 8, in conjunction with the servo motor 8, precisely controls the rotation speed, providing high torque output. This design ensures stable raising and lowering of the material preparation table even under high loads, without problems such as jamming or shaking. Furthermore, the gradual change in the pitch on the surface of the lead screw 10 achieves a smooth transition from low to high loads, balancing efficiency and power, further improving the overall production efficiency of the device.

[0030] Once the device reaches the predetermined height, motor 8 shuts off precisely. At this point, the fixed base 9 stops rotating. Because the lead screw 10 and the fixed base 9 are tightly connected by threads, the device is firmly fixed under the combined influence of friction and other forces, preventing it from descending and providing a reliable locking function. However, in actual use, situations may arise where the object being carried is too heavy, leading to excessive load. In such cases, the device is equipped with an advanced overload protection mechanism. Hydraulic cylinder 13 will quickly activate, pushing the platform 14 upward to bear part of the load, reducing damage to the device due to overload, effectively protecting the device from overload, and extending its service life.

[0031] Second embodiment

[0032] according to Figure 3 As shown, for height adjustment, the motor 8 drives the main pulley 5 to rotate, which in turn drives the auxiliary pulley 3 to rotate via the belt 4, causing the fixed seat 9 to rotate. This, in turn, causes the lead screw 10, which is threadedly connected to the fixed seat 9, to move up or down, adjusting the height of the platform 14. For left and right positioning, the electric slide rail 19 installed at the bottom of the mounting base 1 allows for control of the device's left and right movement. Simultaneously, the cooperation between the hollow slide tube and the fixed rod 16, and the slide groove 17 and the connecting rod 18, provides stable guidance for the lifting and lowering and left and right movement of the platform 14. This enables the device to achieve precise positioning, facilitates material placement and retrieval, helps improve production efficiency, enhances material placement accuracy, and strengthens the stability and safety of equipment operation.
