Description

Technical Field

[0001] This utility model relates to the field of material transfer technology, and in particular to a telescopic folding safety guardrail. Background Technology

[0002] A ton bag (also known as a bulk container or jumbo bag) is a flexible transport packaging container mainly used for loading large quantities of bulk powdery or granular materials, such as grains, chemical raw materials, and mineral products. Its load-bearing capacity is typically 0.5-3 tons, and it features large volume, high loading and unloading efficiency, and ease of warehousing and transportation.

[0003] After being filled with materials, ton bags need to be moved using machinery (such as transfer machines). However, due to their excessive weight, aging, or unstable hooks, ton bags are prone to sudden breakage and falling. Existing transportation equipment lacks protection during use, which can easily cause injury to accompanying personnel. Furthermore, after a ton bag falls, it is difficult to clean it up, increasing the amount of manual labor. Therefore, a telescopic and foldable safety guardrail is proposed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies, such as lack of protection, easy harm to accompanying personnel, and difficulty in cleaning up dropped ton bags, which increases manual labor. Therefore, a telescopic and foldable safety guardrail is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The telescopic folding safety guardrail includes a connecting frame for connecting to a transfer machine and a fall protection mechanism to prevent ton bags from falling. A hanging piece is installed on one side of the connecting frame for hanging ton bags, and a telescopic piece is installed between the fall protection mechanism and the connecting frame for adjusting the position of the fall protection mechanism.

[0007] The fall protection mechanism includes a U-shaped fixed frame, with fall protection components on both sides of the fixed frame. Each fall protection component includes a flip plate, which is hinged to one side of the fixed frame. Multiple sleeves are fixed to one side of the flip plate, and fall protection rails slide inside each sleeve. The fall protection rails are L-shaped and their bottoms are located below the ton bag after it is hung. Limit rails are welded to one side of the fall protection rails at both ends to limit the movement of the ton bag from the side.

[0008] Two drive components are respectively located on one side of the two flip plates. The drive components drive the anti-fall device to flip upward to increase the space when the ton bag is hung.

[0009] As a further embodiment of this utility model, the hanging component includes a cantilever rod welded to one side of the connecting frame, with a hook rotatably connected to the end of the cantilever rod away from the connecting frame for hanging ton bags.

[0010] As a further embodiment of this utility model, the telescopic component includes two sleeves, both of which are welded to one side of the connecting frame. Each sleeve has a rod inserted into it, and the rods are fixed to the fixed frame. The component also includes a second hydraulic cylinder, which is rotatably connected to the bottom of the connecting frame. One end of the hydraulic rod of the second hydraulic cylinder is rotatably connected to the bottom of the fixed frame.

[0011] As a further embodiment of this utility model, both the connecting frame and the sleeve are welded with support rods to the cantilever rod.

[0012] As a further embodiment of this utility model, the driving component includes a first hydraulic cylinder, a fixed plate, and a driving seat. The first hydraulic cylinder is rotatably connected to the bottom of the fixed frame, and a driving rod is rotatably connected to one end of the piston rod of the first hydraulic cylinder. The fixed plate is fixed to one side of the fixed frame, and an intermediate rod is rotatably connected between the driving rod and the fixed plate. The driving seat is fixed to one side of the flipping plate, and the bottom of the driving rod is rotatably connected to the driving seat.

[0013] As a further embodiment of this invention, a spring is installed between the top of the fall arrestor and the top of its corresponding sleeve via a spring seat.

[0014] As a further improvement of this utility model, a plurality of connecting seats are welded to one side of the connecting frame for connection with the transfer machine.

[0015] In this application, during use, the device is connected to the transfer machine via the connecting seat on the connecting frame. The transfer machine moves the equipment. When hanging the ton bag, the first hydraulic cylinder drives the drive rod to flip the anti-fall guardrails on both sides, making the anti-fall guardrails face upwards. The fixing frame is then moved to the side closer to the transfer machine to prevent it from occupying too much space when hanging the ton bag. After the ton bag is hung on the hook, the second hydraulic cylinder is activated to move the fixing frame to both sides of the ton bag. Similarly, the first hydraulic cylinder is activated to flip and lower the anti-fall guardrails on both sides. At this time, the bottom of the anti-fall guardrails is below the ton bag, and the limit bars on both sides are located on both sides of the ton bag, thus providing comprehensive protection for the ton bag and preventing it from falling to the ground when moving with the loader, preventing injury to accompanying personnel, and improving the safety of ton bag movement. When the ton bag falls, the spring at the top of the anti-fall guardrail can also play a buffering role, avoiding the problem of severe shaking of the loader and deformation of the anti-fall guardrail caused by a sudden drop, thus improving the service life of the equipment.

[0016] Beneficial effects: In this utility model, the telescopic folding safety guardrail, through the movable and flip-up anti-fall guardrail, can provide comprehensive protection for the ton bag during the transfer process, preventing the ton bag from falling to the ground when moving with the loader, preventing injury to accompanying personnel, and improving the safety of ton bag movement. At the same time, the flip-up and movable setting can also avoid occupying too much space when the ton bag is hung, preventing any impact on the hanging of the ton bag.

[0017] In this utility model, the telescopic folding safety guardrail, by installing a spring at the top of the guardrail, allows the spring at the top of the guardrail to act as a buffer when the ton bag falls, avoiding the problem of severe shaking of the loader and deformation of the guardrail caused by sudden drop, thereby improving the service life of the equipment.

[0018] In this invention, the ton bag is fully protected during the transfer process, preventing it from falling to the ground while moving with the loader, thus preventing injury to accompanying personnel and improving the safety of ton bag movement. The anti-fall barrier's flipping and moving design also avoids occupying too much space when the ton bag is hung, preventing any impact on its placement. Furthermore, the spring at the top of the anti-fall barrier acts as a buffer, preventing sudden drops that could cause severe shaking of the loader and deformation of the anti-fall barrier, thereby extending the equipment's service life.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] In one embodiment: Refer to Figures 1-3 The telescopic and folding safety guardrail includes: a connecting frame 1 for connecting to the transfer machine and a fall protection mechanism for preventing ton bags from falling. A hanging part is installed on one side of the connecting frame 1 for hanging ton bags, and a telescopic part is installed between the fall protection mechanism and the connecting frame 1 for adjusting the position of the fall protection mechanism.

[0025] The anti-fall mechanism includes a U-shaped fixed frame 5, with anti-fall components on both sides of the fixed frame 5. The anti-fall components include a flip plate 9, which is hinged to one side of the fixed frame 5. Multiple sleeves 10 are fixed to one side of the flip plate 9, and anti-fall rails 11 slide inside each sleeve 10. The anti-fall rails 11 are L-shaped and their bottoms are located below the ton bag after it is hung. Limit rails 13 are welded to one side of the anti-fall rails 11 at both ends to limit the sides of the ton bag. When the anti-fall rails 11 are flipped down, their bottoms are located below the ton bag, and the limit rails 13 on both sides are located on both sides of the ton bag, thus providing comprehensive protection for the ton bag and preventing it from falling to the ground when moving with the loader, preventing injury to the accompanying personnel, and improving the safety of the ton bag's movement. The bottoms of the multiple anti-fall rails 11 can be welded together by square tubes and can contact the bottom of the ton bag to support it, reducing the stress on the hook 7 and the hanging straps above the ton bag body, and preventing damage to the ton bag.

[0026] Two drive components 15 are respectively set on one side of the two flip plates 9. The drive components 15 drive the anti-fall device to flip upward to increase the space when the ton bag is hung. The drive components 15 control the anti-fall device to flip upward, thereby preventing it from occupying too much space when hanging the ton bag.

[0027] In this utility model, the hanging component includes a cantilever 6 welded to one side of the connecting frame 1. The end of the cantilever 6 away from the connecting frame 1 is rotatably connected to a hook 7 for hanging ton bags. The cantilever 6 is made of square steel and can hang ton bags through the hook 7. The shape of the hook 7 can be adapted to different ton bag hanging points, such as round hooks, square hooks or J-shaped hooks.

[0028] In particular, the telescopic component includes two sleeves 3, both of which are welded to one side of the connecting frame 1. Each sleeve 3 has a rod 4 inserted into it, and the rods 4 are fixed to the fixed frame 5. It also includes a second hydraulic cylinder 20, which is rotatably connected to the bottom of the connecting frame 1. One end of the hydraulic rod of the second hydraulic cylinder 20 is rotatably connected to the bottom of the fixed frame 5. Activating the second hydraulic cylinder 20 can adjust the position of the fixed frame 5, thereby adjusting the position of the anti-fall component to avoid affecting the operation when hanging the ton bag. At the same time, it can move the anti-fall component to the position of the corresponding ton bag, thereby providing better support for the ton bag when it falls.

[0029] It should be noted that both the connecting frame 1 and the sleeve 3 are welded with support rods 8 to the cantilever rod 6. The support rods 8 support the cantilever rod 6 and improve its support capacity.

[0030] In this utility model, the driving component 15 includes a first hydraulic cylinder 16, a fixed plate 18, and a driving seat 14. The first hydraulic cylinder 16 is rotatably connected to the bottom of the fixed frame 5. One end of the piston rod of the first hydraulic cylinder 16 is rotatably connected to a driving rod 17. The fixed plate 18 is fixed to one side of the fixed frame 5. An intermediate rod 19 is rotatably connected between the driving rod 17 and the fixed plate 18. The driving seat 14 is fixed to one side of the flipping plate 9. The bottom of the driving rod 17 is rotatably connected to the driving seat 14. Activating the first hydraulic cylinder 16 can drive the driving rod 17 to rotate, and under the support of the intermediate rod 19, the flipping plate 9 will flip.

[0031] In another embodiment: Reference Figures 1-3 The telescopic folding safety guardrail has springs 12 installed between the top of the fall arrestor 11 and the top of its corresponding sleeve 10 via spring seats. The springs 12 at the top of the fall arrestor 11 can also act as a buffer to prevent the loader from shaking severely and the fall arrestor 11 from being deformed by suddenly falling ton bags, thus improving the service life of the equipment.

[0032] It should be noted that multiple connecting seats 2 are welded to one side of the connecting frame 1 for connection with the transfer machine.

[0033] In this invention, both the first hydraulic cylinder 16 and the second hydraulic cylinder 20 are connected to the hydraulic system of the transfer machine.

[0034] However, as is well known to those skilled in the art, the working principles and wiring methods of the first hydraulic cylinder 16 and the second hydraulic cylinder 20 are commonplace and are all conventional methods or common knowledge. They will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0035] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
