Description

Technical Field

[0001] This application relates to the field of automated wood processing equipment technology, and more specifically, to a conveying device and forklift with lifting and pushing functions. Background Technology

[0002] In the timber processing industry, forklifts are commonly used handling equipment, primarily for short-distance transportation of materials such as boards and logs. However, traditional forklifts only have basic lifting and lateral movement functions. When materials need to be precisely pushed onto processing tables, drying kilns, or stacking racks, manual adjustment is still required. Especially for long, heavy timber, manual handling is inefficient and poses safety hazards, easily leading to material slippage or worker injuries. Therefore, there is an urgent need for a conveyor system that combines efficient lifting and precise pushing functions to overcome the automation bottleneck in timber transfer, reduce labor costs, and improve operational safety. Utility Model Content

[0003] This application provides a conveying device with lifting and pushing functions. The conveying device includes a main body, a mounting base, a lifting structure, and a pushing structure. The main body includes a base and two parallel support rods vertically fixed on the base. The mounting base is disposed between the two support rods. The lifting structure includes a sliding seat, a lifting platform, and a hydraulic cylinder. The sliding seat is located between the two support rods and can slide up and down. The lifting platform is fixed to the front end of the sliding seat. The hydraulic cylinder is mounted on the mounting base, and the piston rod end of the hydraulic cylinder is connected to the sliding seat. The pushing structure includes a pushing motor and a pushing rod. The pushing motor is mounted on the mounting base, and the pushing rod is fixed to the output shaft of the pushing motor. The pushing structure is used to push the material on the lifting platform outward.

[0004] In some embodiments, the inner sides of the two support rods are provided with sliding grooves, the two sliding grooves are symmetrically arranged, and two sets of rollers are symmetrically arranged on both sides of the sliding seat, the rollers making rolling contact with the inner wall of the sliding groove.

[0005] In some embodiments, the support rod has a slot distributed along its length on one side adjacent to the slide groove, and the mounting base plate can move up and down along the slot and be locked onto the slot by screws.

[0006] In some embodiments, the support rod has guide grooves distributed along its length on its outer side facing away from the slide groove. The main body also includes a handrail and a connecting plate. The two connecting plates are fixed to both ends of the handrail, and the free ends of the connecting plates are snapped and fixed to the guide grooves.

[0007] In some embodiments, the top of the support rod is provided with a transverse connecting rod, a fixed pulley is installed on the connecting rod, and the mounting base plate is connected to an external lifting drive mechanism through a steel cable wound around the fixed pulley.

[0008] This application also provides a forklift, characterized in that it includes forks and the aforementioned conveying device, wherein the two forks are horizontally arranged for lifting materials. The conveying device is fixed to the two forks via the base.

[0009] This application utilizes a hydraulic cylinder to drive the sliding seat to rise and fall along the support rod, achieving stable lifting and precise height adjustment of the lifting platform, thus solving the problems of tilting and unstable load in traditional forklift lifting. The push motor and push rod are integrated into the mounting base, allowing for direct horizontal pushing of materials to the processing platform after the lifting platform is fixed, avoiding secondary manual handling, and is particularly suitable for long-distance directional transport of long timber.

[0019] Please see Figures 1 to 3 This application provides a conveying device 100 with lifting and pushing functions. The conveying device 100 includes a main body 10, a mounting base 20, a lifting structure 30, and a pushing structure 40. The main body 10 includes a base 11 and two parallel support rods 12 vertically fixed on the base 11. The mounting base 20 is disposed between the two support rods 12. The lifting structure 30 includes a sliding seat 31, a lifting platform 32, and a hydraulic cylinder 33. The sliding seat 31 is located between the two support rods 12 and can slide up and down. The lifting platform 32 is fixed to the front end of the sliding seat 31. The hydraulic cylinder 33 is mounted on the mounting base 20, and the piston rod end of the hydraulic cylinder 33 is connected to the sliding seat 31. The pushing structure 40 includes a pushing motor 41 and a pushing rod 42. The pushing motor 41 is mounted on the mounting base 20, and the pushing rod 42 is fixed on the output shaft of the pushing motor 41. The pushing structure 40 is used to push the material from the lifting platform 32 outward.

[0020] This application utilizes a hydraulic cylinder 33 to drive the sliding seat 31 to rise and fall along the support rod 12, achieving stable lifting and precise height adjustment of the lifting platform 32, thus solving the problems of easy tilting and unstable load in traditional forklift lifting. The push motor 41 and push rod 42 are integrated into the mounting base plate 20, allowing for direct horizontal pushing of materials to the processing platform after the lifting platform 32 is fixed, avoiding secondary manual handling, and is particularly suitable for long-distance directional transport of long-sized timber. The double support rods 12 and the sliding seat 31 cooperate to form a rigid guiding structure, ensuring synchronization of the lifting and pushing process and reducing the risk of material slippage. The overall modular design of the device allows for quick connection with forklift forks, compatibility with existing equipment upgrade needs.

[0021] For details, please continue reading Figures 1 to 3The main body 10 includes a base 11, support rods 12, and connecting rods 13. Two parallel support rods 12 are vertically fixed to the base 11. Three consecutive sides of the support rods 12 are provided with sliding grooves 121, slots 122, and guide grooves 123, all extending along the length direction. The two sliding grooves 121 and the two slots 122 are symmetrically arranged about the central plane. The top connecting rod 13 is arranged laterally, with both ends inserted into the sliding grooves 121. A fixed pulley 131 is installed at the lower part of the middle for winding steel cables to assist in adjusting the height of the mounting base plate 20.

[0022] Furthermore, in order to facilitate the handling of heavier plates, the main body 10 also includes a handrail 14 and a connecting plate 15. The two connecting plates 15 are fixed to both ends of the handrail 14, and the free ends of the connecting plates 15 are snapped and fixed on the guide groove 123.

[0023] The mounting base plate 20 is bent downward on both sides to form two lugs 21. The two lugs 21 are locked and fixed to the slot 122 by a screw structure. After the screws are loosened, they can slide up and down along the slot 122 to adapt to different processing platform heights. After adjustment, they are re-locked to ensure structural rigidity.

[0024] Please see Figure 1 and Figure 2 The lifting structure 30 includes a sliding seat 31, a lifting platform 32, and hydraulic cylinders 33. Two sets of rollers 311 are symmetrically arranged on both sides of the sliding seat 31. The rollers 311 extend into the slide groove 121 and roll in contact with the inner wall of the slide groove 121. The ratio of the diameter of the rollers 311 to the width of the slide groove 121 is 1:1.05 to enhance the lifting guidance accuracy, reduce friction, avoid wobbling, and extend the life of the device. The lifting platform 32 is fixed to the front end of the sliding seat 31. Specifically, the lifting platform 32 is formed by combining two parallel fixed rods, one end of which is fixed to the front end of the sliding seat 31. Two hydraulic cylinders 33 are symmetrically fixed to the upper surface of the mounting base 20. The piston rods of the hydraulic cylinders 33 pass downward through the mounting base 20, and their ends are fixedly connected to the sliding seat 31 by welding, snap-fitting, or other methods. The arrangement of the two hydraulic cylinders 33 can balance the driving force and prevent uneven lifting load.

[0025] Please see Figure 1 and Figure 2 The pushing structure 40 is used to push the material from the lifting platform 32 outward. Specifically, the pushing structure 40 includes a pushing motor 41 and a pushing rod 42. The pushing motor 41 is mounted in the middle of the mounting base plate 20, located between two hydraulic cylinders 33. The pushing rod 42 is fixed to the output shaft of the pushing motor 41, and the pushing rod 42 is perpendicular to the output shaft. The drive motor drives the output shaft to extend and retract, thus pushing the material from the lifting platform 32 onto the processing table.

[0026] Linkage control logic: After the lifting structure 30 reaches the set height, the position sensor (not shown) triggers the push motor 41 to start, and the output shaft extends and retracts at a constant speed of 0.2m / s to ensure that the board is pushed smoothly to the processing table.

[0027] Please see Figure 1 This application also provides a forklift 500, which includes two parallel forks 510. The aforementioned conveying device 100 is fixed to the two forks 510 via a base 11. The forks 510 of the forklift 500 are connected to the base 11 of the conveying device 100 by screws. The conveying device 100 does not rely on the forklift for independent operation. The modification time is ≤10 minutes, and it is compatible with more than 90% of standard forklift models.
