Description

TECHNICAL FIELD

[0001] The utility model relates to stone material moving technical field, concretely is a large -scale stone material automatic clamping plate car. BACKGROUND

[0002] In the field of stone processing and transportation, the handling and installation of large stones have always been a technical problem. The traditional method usually requires a large number of manpower to handle and position the stone, which not only is inefficient, but also has safety hazards. With the progress of science and technology, the stone industry has a higher demand for automation and mechanization to improve production efficiency and reduce labor intensity.

[0003] The applicant found that during the clamping of the stone, manual assistance is often required, especially during the clamping and handling of the stone, which not only increases the labor intensity of the workers and reduces the work efficiency, but also easily causes the stone to scratch the hands of the workers during manual operation. If the stone is not fixed stably and falls accidentally, it will cause immeasurable harm to the workers. Based on this, the utility model designs a large-scale stone automatic clamping plate car to solve the above problems. UTILITY MODEL CONTENT

[0022] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please refer to Figures 1-3 A large-scale automatic stone clamping cart, comprising:

[0024] The frame 1 has rollers 2 installed at the bottom for moving the entire vehicle body, and a handrail 3 installed at the top for pushing by the worker.

[0025] The working mechanism is installed on the front of the frame 1 and is used for clamping the stone. The working mechanism includes a rotating component, a driving component and a linkage component. The rotating component is located on the front of the frame 1 and is used to adjust the stone clamping angle. The driving component is installed at the bottom of the rotating component and is used to clamp and fix the stone. The linkage component is installed on one side of the driving component and is used to fix the stone at different positions.

[0026] The rotating assembly is installed on the work frame 4 on the front of the frame 1. Fixed seats 5 are installed on both sides of the work frame 4. A rotating shaft 6 is installed between the fixed seats 5. A rotating plate 7 is installed on the outer ring of the rotating shaft 6. The work frame 4 and the frame 1 are fixedly connected by reinforcing ribs 8.

[0027] In this embodiment of the invention, the frame 1 serves as the supporting structure for the entire device. The rollers 2 at its bottom facilitate the movement of the entire device, while the handle 3 at the top facilitates pushing and operating by the worker. A work frame 4 is mounted on the front of the frame 1. The work frame 4 is securely connected to the front of the frame 1 via fixed seats 5 on both sides. A rotating shaft 6 installed between the fixed seats 5 allows the rotating plate 7 to rotate.

[0028] Please refer to Figures 1-4The drive assembly includes a drive frame 9 mounted on the bottom of the rotating plate 7. A servo motor 10 is mounted on one side of the drive frame 9. The output shaft of the servo motor 10 is fixedly connected to a drive screw 11. The two sides of the drive screw 11 have opposite thread directions. A connecting frame 12 is also mounted on the bottom of the rotating plate 7. A linkage screw 13 is mounted in the inner cavity of the connecting frame 12. The two sides of the linkage screw 13 have opposite thread directions. The outer rings of the drive screw 11 and the linkage screw 13 are both threadedly connected to a moving block 14. A clamping plate 15 is mounted on the bottom of the moving block 14.

[0029] Limiting rods 16 are installed in the inner cavities of both the drive frame 9 and the connecting frame 12. The moving block 14 is inserted through the outer ring of the limiting rod 16. The linkage assembly includes a connecting roller 17 installed on one side of the drive screw 11 and the linkage screw 13. The connecting rollers 17 are connected by a belt 18.

[0030] In this embodiment of the invention, after the servo motor 10 is started, its output shaft drives the drive screw 11 to rotate. Since the threads on both sides of the drive screw 11 have opposite directions, when the drive screw 11 rotates, the two moving blocks 14 move towards each other along the thread direction of the drive screw 11, and the clamping plate 15 at the bottom of the moving blocks 14 clamps the stone. The linkage assembly achieves synchronous rotation of the drive screw 11 and the linkage screw 13 through the connecting roller 17 and the belt 18. When the servo motor 10 is started, the rotation of the drive screw 11 is transmitted to the linkage screw 13 through the belt 18, ensuring that the two work synchronously. The linkage screw 13 also has opposite thread directions, ensuring that the movement of the two moving blocks 14 on the linkage screw 13 is consistent with that of the drive screw 11, thereby further ensuring the uniform clamping force of the clamping plate 15 on different positions of the stone.

[0031] When using the equipment, if it is necessary to pick up the stone, the worker pushes the handle 3 to shift the frame 1 forward, thus changing the frame 1 from being perpendicular to the ground to tilting it, and bringing the work frame 4 closer to the ground. Since the rotating plate 7 is rotatably connected to the fixed base 5 through the rotating shaft 6, the rotating plate 7 is always in a horizontal state due to gravity.

[0032] When the workpiece 4 approaches the stone, the servo motor 10 starts, and its output shaft drives the drive screw 11 to rotate. Since the threads on both sides of the drive screw 11 are in opposite directions, when the drive screw 11 rotates, the two moving blocks 14 move towards each other along the thread direction of the drive screw 11, and the clamping plate 15 at the bottom of the moving blocks 14 clamps the stone. The linkage assembly achieves synchronous rotation of the drive screw 11 and the linkage screw 13 through the connecting roller 17 and the belt 18. When the servo motor 10 starts, the rotation of the drive screw 11 is transmitted to the linkage screw 13 through the belt 18, ensuring that the two work synchronously.

[0033] The linkage screw 13 also has opposite thread directions, ensuring that the movement of the two moving blocks 14 on the linkage screw 13 is consistent with that of the drive screw 11, thereby further ensuring the uniform clamping force of the clamping plate 15 on different positions of the stone. The limiting rod 16 provides a stable guide for the moving blocks 14. The moving blocks 14 slide on the outer ring of the limiting rod 16, effectively preventing the moving blocks 14 from deviating due to thread wear or errors, and ensuring the accuracy and stability of the clamping action.

[0034] Once the stone is clamped, the worker restores the frame 1 to its vertical position before transporting the stone. When it is time to lower the stone, the servo motor 10 is reversed and, in conjunction with the forward tilt of the frame 1, the stone is placed in the designated position.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
