Description

Technical Field

[0001] The utility model relates to the technical field of loading and unloading machines, and more specifically, to a safety protection device for track-type loading and unloading machines. Background Art

[0002] The rail-mounted loader and unloader is a process equipment used in the field of materials science. It can clamp workpieces from the ground and send them to material processing equipment such as forging hammers, press anvils and heating furnaces for material processing. At the same time, it is convenient to remove materials from the processing equipment. It has both loading and unloading functions, so it is called a loader and unloader.

[0003] Based on the above, the inventors found that the existing loading and unloading machines use telescopic rods and clamps to clamp materials, but the materials are heavy, and the clamping parts of the loading and unloading machines lack a supporting structure. Once the materials become loose and fall, it will cause serious safety impacts on the operators and surrounding processing equipment. Therefore, in view of this, the inventors have studied and improved the existing structure and provided a rail-type loading and unloading machine safety protection device in order to achieve a more practical purpose.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026] Example:

[0027] See also Figure 1-4 , the rail-type loading and unloading machine safety protection device includes a driving rod 1, one end of the driving rod 1 is fixedly connected to a clamping disk 2, and the top surface of the driving rod 1 is fixedly connected to a driving motor 3, an adjusting rod 4 is provided through the middle of the clamping disk 2, and a transmission belt 5 is sleeved on the outer side of the output end of the driving motor 3 and the opposite surface of the upper end of the adjusting rod 4, a support plate 6 is provided at the lower end of the adjusting rod 4, and a limit assembly 9 is provided on the outer side of the upper and lower ends of the adjusting rod 4, a turning handle 8 is provided at one end of the support plate 6, and a group of guide rods 10 are fixedly connected to the top surface of one end of the support plate 6, and one end of the turning handle 8 is fixedly connected to a connecting shaft 11, and the two ends of the connecting shaft 11 are respectively fixedly connected to a threaded ring 12 and a movable ring 13;

[0028] The limiting assembly 9 includes a limiting sleeve 14, a group of support rods 15 are fixedly connected to the outside of the limiting sleeve 14, and a swivel 16 is movably connected to the inside of the limiting sleeve 14, and a group of balls 7 are movably connected to the upper and lower sides of the swivel 16. In order to ensure the rotational stability of the adjusting rod 4, the limiting assembly 9 is provided.

[0029] See Figure 2 The guide rod 10 passes through the lower end of the adjusting rod 4, and the guide rod 10 is slidably connected to the lower end of the adjusting rod 4. The guide rod 10 plays a limiting role to ensure the stability of the support plate 6 during vertical adjustment.

[0030] See Figure 3 The threaded ring 12 is located at the lower end of the adjusting rod 4 and is threadedly connected to the adjusting rod 4. The connecting shaft 11 is rotated by turning the handle 8, thereby causing the threaded ring 12 to rotate inside the adjusting rod 4.

[0031] See Figure 3 The movable ring 13 is located at one end of the support plate 6, and the movable ring 13 is movably connected to the support plate 6. The rotation of the threaded ring 12 drives the connecting shaft 11 to adjust its position, and the movable ring 13 drives the support plate 6 to slide vertically.

[0032] See Figure 4 The support rod 15 is L-shaped, and one end of the support rod 15 away from the limiting sleeve 14 is fixedly connected to the clamping disk 2, and the limiting sleeve 14 is limited and fixed by the support rod 15.

[0033] See Figure 4 The two swivels 16 are fixedly connected to the upper and lower ends of the adjusting rod 4 respectively. When the adjusting rod 4 rotates, the two swivels 16 are driven to rotate synchronously. The limiting sleeve 14 cooperates with the swivel 16 to play the role of limiting support, ensuring the rotation stability of the adjusting rod 4.

[0034] See Figure 4 The ball 7 is movably connected to the swivel 16, and one side of the ball 7 is in contact with the inner surface of the limiting sleeve 14. When the swivel 16 rotates, the ball 7 rubs against the inner surface of the limiting sleeve 14, causing the ball 7 to rotate on its own, thereby reducing the rotational resistance of the swivel 16.

[0035] During use: the driving rod 1 drives the clamping disk 2 to move, so that a pair of clamping pliers on the front side of the clamping disk 2 clamps and fixes the material, and then moves the material to the processing location. During this process, the driving motor 3 cooperates with the transmission belt 5 to rotate the adjusting rod 4. When the adjusting rod 4 rotates, it drives the two swivels 16 to rotate synchronously. The limiting sleeve 14 cooperates with the swivel 16 to play the role of limiting support, ensuring the rotation stability of the adjusting rod 4. When the swivel 16 rotates, the ball 7 rubs against the inner surface of the limiting sleeve 14, and the ball 7 rotates by itself, thereby reducing the rotation resistance of the swivel 16 and ensuring the rotation stability of the adjusting rod 4. After that, the adjusting rod 4 cooperates with the guide rod 10 and the connecting shaft 11 to rotate the support plate 6. The supporting position of the support plate 6 is moved to the bottom of the material to support the material and prevent the material from falling during transportation, which plays a role in safety protection for the operators and surrounding processing equipment. After arriving at the processing location, the drive motor 3 is rotated in the opposite direction, and the support plate 6 is moved out from the bottom surface of the material. Then the clamping disk 2 releases the material and places it in the processing position for processing. According to the length specification of the material, the connecting shaft 11 can be rotated by the turning handle 8, and then the threaded ring 12 can be rotated inside the adjusting rod 4. The rotation of the threaded ring 12 drives the connecting shaft 11 to adjust the position, and cooperates with the movable ring 13 to drive the support plate 6 to slide vertically to adjust the support position.
