[0019] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] like Figures 1 to 4 As shown, a chain-type lifting and transferring machine according to the first aspect of this utility model mainly consists of three parts: a lifting drive module 1, a transferring drive module 2, and a double-row chain 3. The lifting drive module 1 is used to realize the vertical lifting movement of the equipment. The transferring drive module 2 is installed on the upper part of the lifting drive module 1 and is responsible for the horizontal transferring action. The double-row chain 3 is symmetrically installed on the upper part of the transferring drive module 2 and is used to carry and transport materials, as detailed below:

[0021] The first base 11 of the lifting drive module 1 serves as the supporting foundation for the entire module. It is made of high-strength steel plate and has a hollow structure inside for installing the lifting drive motor 13 and related transmission components. A lifting frame 12 is set above the first base 11. The lifting frame 12 is also made of steel plate and has guide rollers 112 symmetrically rotatably connected to its inner side. The guide rollers 112 are connected to the lifting frame 12 through bearings to ensure flexible rotation.

[0022] The lifting drive motor 13 is fixedly mounted on a motor bracket inside the first base 11, and its drive end is connected to the first double-row sprocket 14 via a coupling. Bearing seats 15 are symmetrically mounted on both sides inside the first base 11, and deep groove ball bearings are installed inside the bearing seats 15. The first shaft 16 is rotatably connected through these bearings. A single-row sprocket 17 is mounted on the outside of the first shaft 16. The single-row sprocket 17 and the first double-row sprocket 14 are connected by a chain to form a transmission connection. When the lifting drive motor 13 starts, it can drive the first double-row sprocket 14 to rotate, thereby driving the single-row sprocket 17 and the first shaft 16 to rotate synchronously via the chain.

[0023] Cranks 18 are connected to both ends of the first shaft 16, and the cranks 18 and the first shaft 16 are connected by a key to achieve torque transmission. The other end of the crank 18 is rotatably connected to the drive roller 19 via a cam shaft. The drive roller 19 is made of high-strength wear-resistant material and is connected to the cam shaft via a rolling bearing. The bottom end of the lifting frame 12 is symmetrically connected to "U"-shaped wheel grooves 110, the opening of which faces the drive roller 19, allowing the drive roller 19 to roll inside the wheel groove 110. When the first shaft 16 rotates, the cranks 18 perform circular motion, driving the drive roller 19 to roll within the wheel groove 110, thereby converting the circular motion into the vertical linear motion of the lifting frame 12.

[0024] Guide columns 111 are installed at the four corners of the top of the first base 11. The guide rollers 112 inside the lifting frame 12 roll along the two sides of the guide columns 111, which can greatly improve the stability of the lifting frame 12 during the lifting process.

[0025] The second base 21 of the transfer drive module 2 is installed on the upper part of the lifting frame 12 of the lifting drive module 1 and is fixedly connected to the lifting frame 12 by bolts. The second base 21 is also made of welded steel plate and has a hollow internal structure for installing the transfer drive motor 22 and related transmission components;

[0026] The transfer drive motor 22 is fixedly mounted on a motor bracket inside the second base 21, and its drive end is connected to the second double-row sprocket 23 via a coupling. Inside the second base 21, a second shaft 24 is rotatably connected via a bearing seat. A third double-row sprocket 25 is mounted on the outside of the second shaft 24, and the second double-row sprocket 23 and the third double-row sprocket 25 are connected by a chain. When the transfer drive motor 22 starts, it drives the second double-row sprocket 23 to rotate, which in turn drives the third double-row sprocket 25 and the second shaft 24 to rotate synchronously via the chain.

[0027] Both ends of the second shaft 24 extend to the outside of the second base 21 and are respectively equipped with fourth double-row sprockets 26. The fourth double-row sprockets 26 are connected to the driven end of the double-row chain 3 by a chain. When the second shaft 24 rotates, the double-row chain 3 can be driven to run by the fourth double-row sprockets 26 and the chain to realize the transfer and conveying of materials.

[0028] The double-row chain 3 adopts a double-row structure design, and its chain is composed of inner chain plates, outer chain plates, pins, and rollers. The driving end of the double-row chain 3 is connected to the fourth double-row sprocket 26 of the transfer drive module 2 via a chain. A carrying rail is set on top of the double-row chain 3, and materials are placed on the carrying rail. When the double-row chain 3 is running, the friction between the rollers and the rail achieves rapid material conveying. The transmission speed of the double-row chain 3 can be adjusted by adjusting the speed of the transfer drive motor 22 to adapt to different production needs.

[0029] During operation, the lifting drive motor 13 starts, and its drive end drives the first double-row sprocket 14 to rotate. Since the single-row sprocket 17 and the first double-row sprocket 14 are connected by a chain, the rotation of the first double-row sprocket 14 will cause the chain to move, thereby driving the single-row sprocket 17 to rotate. The single-row sprocket 17 is installed on the first shaft rod 16, and the first shaft rod 16 rotates accordingly. The crank 18 connected to the end of the first shaft rod 16 also makes a circular motion. The crank 18 is rotationally connected to the drive roller 19 through a convex shaft. The circular motion of the crank 18 causes the drive roller 19 to perform an up-and-down reciprocating motion. The bottom end of the lifting frame 12 is symmetrically connected with a "U"-shaped wheel groove 110, and the opening of the wheel groove 110 faces the drive roller 19. The drive roller 19 rolls inside the wheel groove 110. When the drive roller 19 moves upward, it pushes the wheel groove 110 to move upward, thereby带动 the lifting frame 12 to rise; when the drive roller 19 moves downward, the lifting frame 12 descends under its own gravity. At the same time, the guide posts 111 installed at the top of the first base 11 play a guiding role, and the guide rollers 112 symmetrically and rotationally connected to the inner side of the lifting frame 12 roll along both sides of the guide posts 111 to ensure that the lifting frame 12 remains stable during the lifting process and does not shift;

[0030] When the lifting frame 12 rises to the designated position, this process is monitored by a sensor, which belongs to the prior art and will not be elaborated here. The transfer drive motor 22 starts, and its drive end drives the second double-row sprocket 23 to rotate. The second double-row sprocket 23 and the third double-row sprocket 25 are connected by a chain. Therefore, the rotation of the second double-row sprocket 23 will cause the chain to move, thereby driving the third double-row sprocket 25 to rotate. The third double-row sprocket 25 is installed on the second shaft rod 24, and the second shaft rod 24 rotates accordingly. Both ends of the second shaft rod 24 extend to the outside of the second base 21 and are equipped with fourth double-row sprockets 26. The fourth double-row sprockets 26 and the driven end of the double-row chain 3 are connected by a chain. The rotation of the second shaft rod 24 drives the fourth double-row sprockets 26 to rotate, thereby driving the double-row chain 3 to operate through the chain. The specific structure and principle of the double-row chain 3 are well-known prior arts and will not be elaborated here. After the double-row chain 3 operates, the goods placed on the double-row chain 3 move with the movement of the double-row chain 3 to实现 the function of transferring goods. When the goods are transferred to the designated position, the transfer drive motor 22 stops operating, the double-row chain 3 stops moving, and the goods stay at the corresponding position. Subsequently, the lifting drive motor 13 rotates in the reverse direction to make the lifting frame 12 descend and return to the initial position, waiting for the next work cycle.

[0031] Finally, it should be noted that special tensioning wheels are equipped on the chain drive paths between the single-row sprocket 17 and the first double-row sprocket 14, between the second double-row sprocket 23 and the third double-row sprocket 25, and between the fourth double-row sprocket 26 and the double-row chain 3 to adjust the tension of each chain.

[0032] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.

[0033] The terms such as "upper," "lower," "left," "right," and "middle" used in this specification are merely for clarity of description and are not intended to limit the scope of implementation of this utility model. Any changes or adjustments to their relative relationships, without substantially altering the technical content, shall also be considered within the scope of implementation of this utility model.
