[0014] The lifting and conveying device of this utility model has the following advantages compared with the prior art:

[0015] 1. By coordinating four electric push rods to move the conveyor frame up and down, and by rotatably connecting multiple drive rollers to the top of the conveyor frame, the workpiece can move synchronously up and down with the conveyor frame when placed on the multiple drive rollers, thereby lifting the workpiece to a predetermined height. Simultaneously, the multiple drive rollers can coordinate to move the workpiece, thus conveying it to a predetermined position, improving the user experience. By mounting multiple first helical gears on the outside of the multiple drive rollers and multiple second helical gears on the outside of the drive shaft, and by meshing the first and second helical gears, the drive shaft rotates. This drives the multiple drive rollers to rotate synchronously, improving the stability of the workpiece movement.

[0016] 2. By installing multiple slide rails inside the frame and having each slide rail pass through the grooves of multiple slide blocks, the slide blocks can move up and down along the slide rails via the grooves, thereby improving the stability of the lifting connecting frame and the conveyor frame moving up and down.

[0017] 3. By passing the first threaded rod through the second connecting plate, two fixing nuts are fitted onto the outside of the first threaded rod and made to fit against the upper and lower sides of the second connecting plate respectively, so as to fix the first threaded rod on the second connecting plate. This allows the fixing nuts to be rotated to adjust the distance between the second connecting plate and the base plate, thereby achieving the leveling of the frame.

[0018] 4. By installing the protective cover on the support beam and surrounding the outside of the first and second helical gears, the protective cover protects the first and second helical gears, thereby preventing other parts from falling between them and thus avoiding damage to the first and second helical gears, thereby improving product quality; by connecting the U-shaped handle to the protective cover, the protective cover can be moved by the handle, thereby facilitating the handling of the protective cover and improving the user experience of the product.

[0019] 5. By mounting the second sprocket on the outside of the drive shaft and mounting the chain on the outside of both the first and second sprockets, when the drive unit drives the first sprocket to rotate, the first sprocket drives the drive shaft to rotate through the second sprocket and the chain, thereby providing power for rotating the drive shaft.

[0020] 6. By mounting the grating detector at the end of the frame and positioning it above the drive roller, when a workpiece is placed on the drive roller and moved to the end of the frame, the workpiece moves between the grating detectors. This allows the grating detectors to detect when the workpiece has been removed from the drive roller, ensuring the workpiece is transported to the designated position and improving the user experience. By installing multiple buffer mechanisms within the frame and positioning them below the lifting connecting frame, when the lifting connecting frame moves downwards to its lowest point, the buffer mechanisms contact the lifting connecting frame, preventing rigid contact between the lifting connecting frame and the frame and thus avoiding damage to the lifting connecting frame, thereby improving product quality.

[0021] 7. By fitting a spring onto the outside of the buffer rod, connecting one end of the spring to the other end of the buffer rod, and connecting the other end of the spring to the top of the buffer seat, the buffer seat supports the buffer rod through the spring. This allows the spring to undergo elastic deformation when the other end of the buffer rod contacts the lifting connecting frame, thereby preventing rigid contact between the lifting connecting frame and the machine frame and improving product quality.

Detailed Implementation

[0029] The following are specific implementation cases and appendices. Figures 1 to 5 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0030] A lifting and conveying device, such as Figures 1 to 5 As shown, the lifting and conveying device includes: a frame 10, electric push rods 11, a conveyor frame 12, drive rollers 13, a support beam 14, a drive shaft 15, a first helical gear 16, a second helical gear 17, a guide seat, and a guide rod 19; four electric push rods 11 are installed inside the frame 10; the conveyor frame 12 is located above the frame 10, and the bottom of the conveyor frame 12 is simultaneously connected to the output ends of the four electric push rods 11; multiple drive rollers 13 are rotatably connected to the top of the conveyor frame 12; the support beam 14 is provided with a receiving groove, the support beam 14 is connected to the side wall of the frame 10, and the support beam 14 is located on one side of the multiple drive rollers 13; the ... four electric push rods 12 are located above the frame 10, and the bottom of the conveyor frame 12 is connected to the output ends of the four electric push rods 11; multiple drive Shaft 15 is embedded in the receiving groove of support beam 14, drive shaft 15 is rotatably connected to support beam 14, and drive shaft 15 is perpendicular to transmission roller 13; multiple first helical gears 16 are respectively fitted on the outside of multiple transmission rollers 13; multiple second helical gears 17 are fitted on the outside of drive shaft 15, and second helical gears 17 mesh with first helical gears 16; guide seats are provided with guide holes, and multiple guide seats are installed on the top of frame 10; one end of multiple guide rods 19 is connected to the bottom of conveyor frame 12, the other end of guide rods 19 passes through the guide holes of multiple guide seats, and the other end of multiple guide rods 19 is embedded in frame 10.

[0031] By installing four electric push rods 11 inside the frame 10 and connecting the bottom of the conveyor frame 12 to the output ends of the four electric push rods 11 simultaneously, the four electric push rods 11 work together to drive the conveyor frame 12 to move up and down, thereby adjusting the distance between the conveyor frame 12 and the frame 10, and thus adjusting the height of the conveyor frame 12. By rotatably connecting multiple drive rollers 13 to the top of the conveyor frame 12, the conveyor frame 12 supports the multiple drive rollers 13, thereby enabling the drive rollers 13 to rotate on the output frame. When a workpiece is placed on the drive rollers 13, rotating the drive rollers 13 causes the multiple drive rollers 13 to work together to move the workpiece. By connecting the support beam 14 to the side wall of the frame 10, embedding the drive shaft 15 into the receiving groove of the support beam 14, and rotatably connecting the drive shaft 15 and the support beam 14, the frame 10 supports the support beam 14, thereby supporting the drive shaft 15, and enabling the drive shaft 15 to rotate within the receiving groove. By mounting multiple first helical gears 16 on the outside of multiple transmission rollers 13, and mounting multiple second helical gears 17 on the outside of the drive shaft 15, and meshing the second helical gears 17 with the first helical gears 16, the drive shaft 15 can simultaneously drive the multiple second helical gears 17 to rotate, thereby enabling the second helical gears 17 to rotate the first helical gears 16, and thus driving the transmission rollers 13 to rotate. By connecting one end of multiple guide rods 19 to the bottom of the conveyor frame 12, the conveyor frame 12 and the multiple guide rods 19 can move up and down synchronously. Multiple guide seats are installed on the top of the frame 10, and the other ends of the guide rods 19 are passed through the guide holes of the multiple guide seats respectively, and the other ends of the multiple guide rods 19 are embedded in the frame 10, so that the frame 10 guides the guide rods 19 through the guide seats, thereby improving the stability of the conveyor frame 12 moving up and down.

[0032] When using the product, the workpiece is placed on the drive roller 13; then, the electric push rod 11 is activated, causing the four electric push rods 11 to work together to move the conveyor frame 12 upward, thereby lifting the workpiece to a predetermined height; then, the drive shaft 15 is activated, causing the drive shaft 15 to drive the drive roller 13 to rotate through the first helical gear 16 and the second helical gear 17, thereby causing the drive roller 13 to move the workpiece, and then removing the workpiece from the drive roller 13 to transport the workpiece to a predetermined height.

[0033] With the above structure, four electric push rods 11 work together to move the conveyor frame 12 up and down, and multiple drive rollers 13 are rotatably connected to the top of the conveyor frame 12. This allows the workpiece to move up and down synchronously with the conveyor frame 12 when it is placed on the multiple drive rollers 13, thereby lifting the workpiece to a predetermined height. Simultaneously, the multiple drive rollers 13 work together to move the workpiece, thus conveying it to a predetermined position and improving the user experience. Multiple first helical gears 16 are respectively mounted on the outside of the multiple drive rollers 13, and multiple second helical gears 17 are mounted on the outside of the drive shaft 15. The first helical gears 16 and second helical gears 17 mesh, rotating the drive shaft 15. This causes the drive shaft 15 to drive the multiple drive rollers 13 to rotate via the first helical gears 16 and second helical gears 17, achieving synchronous rotation of the multiple drive rollers 13 and improving the stability of the workpiece movement driven by the drive rollers 13.

[0034] In embodiments of this utility model, such as Figures 1 to 5 As shown, the lifting and conveying device further includes: a lifting connecting frame 20, a first connecting plate 21, a slide block 22, and a slide rail 23; the lifting connecting frame 20 is connected to the bottom of the conveying frame 12; at least two first connecting plates 21 are respectively connected to both sides of the lifting connecting frame 20; a slide block 22 is provided with a slide groove, and at least two slide blocks 22 are respectively fixed on at least two first connecting plates 21; at least two slide rails 23 are installed in the frame 10, and at least two slide rails 23 pass through the slide grooves of at least two slide blocks 22 respectively.

By installing multiple slide rails 23 in the frame 10 and passing through the slide grooves of multiple slide blocks 22 respectively, the slide blocks 22 can move up and down along the slide rails 23 through the slide grooves, thereby improving the stability of the lifting connecting frame 20 and the conveying frame 12 moving up and down.

By placing the base plate 27 on the ground and welding the base plate 27 to the first threaded rod 25, the base plate 27 supports the first threaded rod 25. By passing the first threaded rod 25 through the second connecting plate 24, two fixing nuts 26 are fitted onto the outside of the first threaded rod 25 and are respectively fitted to the upper and lower sides of the second connecting plate 24, thereby fixing the first threaded rod 25 onto the second connecting plate 24. By rotating the fixing nuts 26, the distance between the second connecting plate 24 and the base plate 27 can be adjusted, thereby leveling the frame 10.

[0038] In embodiments of this utility model, such as Figures 1 to 5 As shown, the lifting and conveying device also includes: a drive unit 28, a first sprocket 29, a second sprocket 30, and a chain 31; the drive unit 28 is provided with an output shaft and is installed at the bottom of the support beam 14; the first sprocket 29 is fitted on the outside of the output shaft of the drive unit 28; the second sprocket 30 is fitted on the outside of the drive shaft 15; and the chain 31 is fitted on the outside of both the first sprocket 29 and the second sprocket 30.

By fitting the second sprocket 30 onto the outside of the drive shaft 15 and fitting the chain 31 onto both the first sprocket 29 and the second sprocket 30, when the drive unit 28 drives the first sprocket 29 to rotate, the first sprocket 29 drives the drive shaft 15 to rotate via the second sprocket 30 and the chain 31, thereby providing power for rotating the drive shaft 15.

[0040] In embodiments of this utility model, such as Figures 1 to 5As shown, the lifting and conveying device also includes: a protective cover 32 and a handle 33; the protective cover 32 is mounted on the support beam 14 and is arranged around the outside of the first helical gear 16 and the second helical gear 17; the handle 33 is U-shaped and is connected to the protective cover 32.

[0041] By installing the protective cover 32 on the support beam 14 and surrounding the outside of the first helical gear 16 and the second helical gear 17, the protective cover 32 protects the first helical gear 16 and the second helical gear 17, thereby preventing other parts from falling between the first helical gear 16 and the second helical gear 17 and thus preventing damage to the first helical gear 16 and the second helical gear 17, thereby improving product quality. By connecting the U-shaped handle 33 to the protective cover 32, the protective cover 32 can be moved by the handle 33, thereby facilitating the handling of the protective cover 32 and improving the user experience of the product.

[0043] By mounting the grating detector 34 at the end of the frame 10 and positioning it above the drive roller 13, when a workpiece is placed on the drive roller 13 and moved to the end of the frame 10, the workpiece moves between the grating detector 34. This allows the grating detector 34 to detect that the workpiece has been removed from the drive roller 13, ensuring that the workpiece is transported to the designated position and improving the user experience. By mounting multiple buffer mechanisms 35 inside the frame 10 and positioning them below the lifting connecting frame 20, when the lifting connecting frame 20 moves downwards to its lowest position, the multiple buffer mechanisms 35 contact the lifting connecting frame 20. This prevents rigid contact between the lifting connecting frame 20 and the frame 10, avoiding damage to the lifting connecting frame 20 and improving product quality.

[0045] By installing the buffer seat 351 inside the frame 10 and passing one end of the buffer rod 352 through the top of the buffer seat 351, the frame 10 supports the buffer seat 351, allowing one end of the buffer rod 352 to move up and down within the buffer seat 351. By fitting a spring 353 onto the outside of the buffer rod 352, connecting one end of the spring 353 to the other end of the buffer rod 352, and connecting the other end of the spring 353 to the top of the buffer seat 351, the buffer seat 351 supports the buffer rod 352 through the spring 353. This ensures that when the other end of the buffer rod 352 contacts the lifting connecting frame 20, the spring 353 undergoes elastic deformation, thereby preventing rigid contact between the lifting connecting frame 20 and the frame 10 and improving product quality.
