Technical Field

[0001] This invention relates to the technical field of construction site operations, and more specifically, to an electric lifting and stacking device and its operating method. Background Technology

[0002] In construction engineering and logistics warehousing scenarios, the stacking and handling of materials typically relies on manual labor, handcarts, or forklifts. Manual labor and handcarts are labor-intensive, inefficient, and prone to causing personal injury. While forklifts offer some stacking capacity, they are expensive, require professional operators, and are unsuitable for complex terrain. Existing technologies include some simple lifting devices, but these still suffer from the following drawbacks: 1) They lack effective guidance and stabilizing structures, making goods prone to swaying and tilting during lifting, posing risks of damage and accidents. 2) They are unsuitable for complex terrain.

[0003] Therefore, there is an urgent need for an electric lifting and stacking device that is stable in lifting and flexible in movement. Summary of the Invention

[0021] Example 1 Figures 1-3 The electric lifting stacking device is described in its entirety. For example... Figure 1-3 As shown, the electric lifting stacking device includes: a frame, including a fixed rod 5 and a support frame 4 for supporting the fixed rod 5; a bracket 3 for carrying materials, which is slidably mounted on the frame; a guide unit including two parallel and vertically fixed sliding rods 10, and two sets of pulleys symmetrically mounted on the back of the bracket 3; a lifting unit including a motor 7, a rope winder 2 driven by the motor 7, a fixed pulley 8, and a steel rope, wherein the fixed pulley 8 is mounted on the top of the fixed rod 5, one end of the steel rope is connected to the bracket 3, and the other end passes over the fixed pulley 8 and is wound around the rope winder 2; and a moving unit installed at the bottom of the frame, wherein the moving mechanism includes multiple casters 6 with braking devices.

[0022] In summary, the control box 1 serves as the control center, with an operating panel 9 above it and an operating panel frame 15 supporting it below. The rope winder 2, motor 7, and locking knob 13 for locking the rope winder are fixed as a single module to the rear of the fixed rod 5. The bracket 3 is located at the front of the fixed rod 5 and is slidably connected to the fixed rod 5 via a slide rod 10 and multiple pulleys 11 mounted thereon. A fixed pulley 8 is mounted upside down at the top center of the fixed rod 5. The top of the bracket 3 is equipped with a hook 12 made of high-strength, wear-resistant material. One end of the steel rope is detachably connected to the hook 12, passes over the fixed pulley 8, and the other end is fixed and wound around the rope winder 2. When the motor 7 drives the rope winder 2 to rotate forward and backward, the bracket 3 can be smoothly raised and lowered along the slide rod 10 by pulling the steel rope.

[0023] In one specific embodiment, each pulley group includes multiple pulleys 11 that roll in contact with the corresponding slide rod 10. That is, two slide rods 10 are fixedly mounted parallel to each other on the front side of the fixed rod 5, forming a stable vertical guide rail. Each pulley group can contain 2-6 pulleys. For example, each group contains 3 pulleys, arranged side-by-side in a vertical row on the back of the bracket 3. That is, the central axes of the three pulleys 11 are on the same vertical line and distributed at equal or unequal intervals. All three pulleys 11 in each pulley group form rolling contact with the corresponding slide rod 10 from the same side. The slide rod 10 is constructed with a flat guide plane, or directly uses a smooth shaft, and the raceway surfaces of the three pulleys 11 simultaneously maintain a tight rolling engagement with the contact surface of the slide rod 10.

[0024] Example 2 An electric lifting stacking device includes: a frame, comprising a fixed rod 5 and a support frame 4 for supporting the fixed rod 5; a bracket 3 for carrying materials, which is slidably mounted on the frame; a guide unit comprising two parallel and vertically fixed sliding rods 10, and two sets of pulleys symmetrically mounted on the back of the bracket 3; a lifting unit comprising a motor 7, a rope winder 2 driven by the motor 7, a fixed pulley 8, and a steel rope, wherein the fixed pulley 8 is mounted on the top of the fixed rod 5, one end of the steel rope is connected to the bracket 3, and the other end passes over the fixed pulley 8 and is wound around the rope winder 2; and a moving unit mounted at the bottom of the frame, the moving mechanism comprising multiple casters 6 with braking devices. A control box 1 serves as the control center, with an operating platform 9 above it and an operating platform frame 15 supporting it below. The bracket 3 is located in front of the fixed rod 5 and is slidably connected to the fixed rod 5 via the sliding rods 10 and multiple pulleys 11 mounted thereon. A fixed pulley 8 is installed upside down at the top center of the fixed rod 5. A hook 12 made of high-strength and wear-resistant material is installed on the top of the bracket 3. One end of the steel rope is detachably connected to the hook 12, passes around the fixed pulley 8, and the other end is fixed and wound on the rope winder 2. When the motor 7 drives the rope winder 2 to rotate forward and backward, the bracket 3 can be pulled up and down smoothly along the slide rod 10 by the steel rope.

[0025] In one specific embodiment, in each pulley group, two pulleys 11 are horizontally arranged side-by-side at the upper end of the back of the bracket, and the third pulley is located at the lower middle position of the back of the bracket, forming a three-point clamping rolling structure. The three pulleys 11 of each pulley group form rolling contact with the corresponding slide rod 10 from different sides. The two upper pulleys 11 clamp the slide rod 10 from the rear side, while the lower pulley 11 abuts against the slide rod 10 from the front side. The design of the double slide rods and pulleys constitutes a stable guiding structure, effectively maintaining the bracket 3 after it has been loaded with materials, preventing any swaying that may occur after loading goods, and ensuring stability.

[0026] In the specific implementation process, a locking module for locking the rotation of the rope reel 2 is also included. In the specific implementation process, the locking module is connected to a locking button located on the operating table.

[0027] For example, the locking module may include a brake disc, a friction block, an adjusting screw, and an external locking knob. When it is necessary to lock the rope winder 2, the operator adjusts the locking knob. The locking knob drives the adjusting screw to rotate towards the brake disc, and the end of the screw pushes the friction block to press against the friction surface of the brake disc. The torque applied by the locking button is converted into an axial thrust of the screw, which generates a large static friction force between the friction block and the brake disc. This achieves mechanical locking of the rope winder. When it is necessary to adjust the bracket height, the locking knob is rotated counterclockwise. The adjusting screw then retracts, and its axial pressure on the friction block is quickly released, separating the friction block from the brake disc, restoring the gap between them. The rope winder 2 and the brake disc can then rotate freely under the drive of the motor 7. The purely mechanical locking mechanism can ensure safety in the event of a power outage or other emergencies, effectively preventing goods from falling.

[0028] In one specific embodiment, the support frame 4 and the operating platform 15 can be an integrated structure, jointly providing stable support for the entire device. Multiple casters 6 at the bottom of the device are equipped with braking functions for easy movement and locking.

[0029] In one specific embodiment, the control box 1 is equipped with a power supply and a cooling fan for dissipating heat from the components and motor 7 inside the box. A cooling fan is installed inside the control box, and a heat dissipation grille 14 is installed on the top of the control box. The heat dissipation system consisting of the fan and the heat dissipation grille 14 can ensure the stability of the electrical components and motor during long-term operation.

[0030] In one specific embodiment, the control panel 9 is equipped with operation buttons for controlling the motor and a display device for displaying status information. In practice, the display device can show the power supply level, the status of the bracket, etc.

[0031] A method for operating an electric lifting stacking device includes the following steps: S110. Release the brakes on the casters and move the frame to the working position.

[0032] S120. Place the material to be transported on the tray.

[0033] S130. Start the motor by pressing the operation button on the control panel of the control box, drive the rope winder to wind and unwind the steel rope, thereby pulling the bracket to rise and fall along the slide bar.

[0034] S140. After the material on the bracket reaches the preset height, the motor is stopped by operating the control panel button of the control box, and the locking button of the locking module is operated to lock the rope winder, thereby fixing the bracket at the preset height.

[0035] In other words, the operator places the goods on the carrier 3, starts the device via the control panel 9 to control the motor, and achieves precise lifting and lowering of the carrier. After reaching the target height, the locking knob 13 is turned to mechanically lock the rope reel 2. After the operation is completed, the brake on the caster wheel 6 is released to move the device to the next working position.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.

[0037] Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be embraced within the invention. No appended diagram markings in the claims should be construed as limiting the scope of the claims.

[0038] Furthermore, it is clear that the word "comprising" does not exclude other units or steps, and the singular does not exclude the plural. Multiple units or systems stated in a system claim may also be implemented by a single unit or system through software or hardware.

[0039] However, those skilled in the art should understand that various modifications can be made to the electric lifting stacking device and the electric lifting stacking device proposed in this invention without departing from the scope of this invention.
