Metal piece reversing conveying mechanism for wave-shaped guardrail

Abstract

This utility model relates to the field of corrugated guardrail technology, and in particular to a reversing conveying mechanism for metal parts of corrugated guardrails. The mechanism includes a conveying mechanism with a fixed frame and multiple conveying rollers mounted on top. In this utility model, through the conveying mechanism and the unloading mechanism, when the corrugated guardrail moves to the top of the conveying rollers, a first electric cylinder drives an electric telescopic guide rail to move, causing the corrugated guardrail to detach from the conveying rollers. The electric telescopic guide rail then moves the corrugated guardrail above the unloading mechanism. Afterward, the first electric cylinder moves downward, and the electric telescopic guide rail slowly resets. Next, a second electric cylinder descends, and the corrugated guardrail moves on top of the stepped frame under its own gravity, thus completing the unloading. This design allows for reversing the conveying of corrugated guardrails, thereby reducing the length of the corrugated guardrail production line and utilizing the space on the side of the production line.

Technical Field

[0001] This utility model relates to the field of wave-shaped guardrail technology, specifically to a metal component reversing conveying mechanism for wave-shaped guardrails. Background Technology

[0002] Corrugated guardrails are semi-rigid crash barriers widely used in highways, urban roads, and bridges. During the production of corrugated guardrails, metal parts are usually deformed by machine extrusion to form a corrugated structure, thereby achieving efficient energy absorption and guidance functions.

[0003] In existing technology, corrugated guardrails are automatically conveyed by a conveyor device during processing, and each process is carried out. The machines required for each process are all on the same horizontal line, which results in a long production line for corrugated guardrail manufacturing machines and poor space utilization on the sides of the machines. Therefore, in order to address the above problems, a metal part reversing conveyor mechanism for corrugated guardrails is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a metal part reversing conveyor mechanism for corrugated guardrails, so as to solve the problems mentioned in the background art of the existing corrugated guardrail production line being too long and having poor space utilization on the side of the machine.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A reversing conveying mechanism for metal parts of a corrugated guardrail includes a conveying mechanism comprising a fixed frame and multiple conveying rollers mounted on top of the conveying mechanism. A feeding mechanism is mounted on one side of the conveying mechanism. A feeding assembly is mounted inside the fixed frame, the feeding assembly including multiple first electric cylinders mounted inside the fixed frame, with a horizontally arranged electric telescopic guide rail mounted on the top of each first electric cylinder. The feeding mechanism includes a stepped frame mounted on one side of the fixed frame, with multiple feeding rollers mounted on the top of the stepped frame, and a second electric cylinder mounted inside the stepped frame. Contact components are mounted on the top of both the electric telescopic guide rail and the first electric cylinders. Each contact component includes a contact block, and anti-slip components for preventing the corrugated guardrail from sliding horizontally are mounted on both sides of the contact block. The first and second electric cylinders are staggered, and the first and second electric cylinders are at the same height.

[0006] Preferably, a travel synchronizer is installed on the inner side of both the fixed frame and the stepped frame.

[0007] Preferably, the anti-slip component includes an extension plate fixedly connected to both sides of the contact block, and a detachable elastic block is installed on the top of the extension plate, with multiple protrusions on the top of the elastic block.

[0008] Preferably, the bottom of the elastic block has a slot, and a locking block fixedly connected to the top of the extension plate is engaged inside the slot.

[0009] Preferably, protective components are installed on the sides of the fixed frame and the stepped frame that are far apart from each other.

[0010] Preferably, the protective component includes a protective plate disposed on one side of the fixed frame and the stepped frame, the protective plate being able to slide up and down on one side of the fixed frame and the stepped frame.

[0011] Preferably, a connecting frame is fixedly connected to one side of the protective plate, and a vertically arranged sliding frame is slidably connected to the outside of the connecting frame. A spring retainer for limiting the sliding of the connecting frame is installed on the outside of the sliding frame. Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, through the set conveying mechanism and unloading mechanism, when the corrugated guardrail moves to the top of the conveying roller, the first electric cylinder can drive the electric telescopic guide rail to move so that the corrugated guardrail is separated from the conveying roller. The operation of the electric telescopic guide rail can drive the corrugated guardrail to move above the unloading mechanism. Then the first electric cylinder can move downward, and the electric telescopic guide rail can slowly return to its original position. Next, the second electric cylinder can descend, and the corrugated guardrail can move on the top of the stepped frame under its own gravity, thereby completing the unloading. This design can reverse the conveying of the corrugated guardrail, thereby reducing the length of the corrugated guardrail production line and making use of the space on the side of the production line. 2. In this utility model, the protective components can limit the corrugated guardrail, preventing it from detaching from the conveying mechanism or unloading mechanism and causing injury to workers. The design of the connecting frame, sliding frame and spring retainer allows the protective plate to slide up and down, making it more convenient for workers to maintain the conveying mechanism and unloading mechanism.

[0017] Please see Figure 1-7 This utility model provides a technical solution: A reversing conveying mechanism for metal parts of a corrugated guardrail includes a conveying mechanism 1. The conveying mechanism 1 includes a fixed frame 11 and multiple conveying rollers 12 mounted on the top of the conveying mechanism 1. A feeding mechanism 2 is mounted on one side of the conveying mechanism 1. A feeding assembly 13 is mounted inside the fixed frame 11. The feeding assembly 13 includes multiple first electric cylinders 131 mounted inside the fixed frame 11. A horizontally arranged electric telescopic guide rail 132 is mounted on the top of the first electric cylinders 131. The feeding mechanism 2 includes a stepped frame 21 mounted on one side of the fixed frame 11. Multiple feeding rollers 22 are mounted on the top of the stepped frame 21. A second electric cylinder 23 is mounted inside the stepped frame 21. A contact assembly 3 is mounted on the top of both the electric telescopic guide rail 132 and the first electric cylinders 131. The contact assembly 3 includes a contact block 31. The contact block 31 has a contact element on both sides to prevent the corrugated guardrail from moving horizontally. The sliding anti-slip component 32; the first electric cylinder 131 and the second electric cylinder 23 are staggered and have the same height. Through the conveying mechanism 1 and the unloading mechanism 2, when the corrugated guardrail moves to the top of the conveying roller 12, the first electric cylinder 131 can drive the electric telescopic guide rail 132 to move so that the corrugated guardrail is separated from the conveying roller 12. The operation of the electric telescopic guide rail 132 can drive the corrugated guardrail to move above the unloading mechanism 2. Then the first electric cylinder 131 can move downward and the electric telescopic guide rail 132 can slowly return to its original position. Next, the second electric cylinder 23 can descend, and the corrugated guardrail can move on the top of the stepped frame 21 under its own gravity, thereby completing the unloading. This design can reverse the conveying of the corrugated guardrail, thereby reducing the length of the corrugated guardrail production line and making use of the space on the side of the production line.

[0018] Both the fixed frame 11 and the stepped frame 21 are equipped with stroke synchronizers 4. The design of the stroke synchronizers 4 can ensure that multiple first electric cylinders 131 and second electric cylinders 23 can move synchronously, thus ensuring the stability of the device operation.

[0019] The anti-slip component 32 includes an extension plate 321 fixedly connected to both sides of the contact block 31. A removable elastic block 322 is installed on the top of the extension plate 321. The top of the elastic block 322 is provided with multiple protrusions 323. The design of the anti-slip component 32 can prevent the wave-shaped guardrail from sliding horizontally.

[0020] The bottom of the elastic block 322 is provided with a slot 324, and the slot 324 is engaged with a block 325 fixedly connected to the top of the extension plate 321. The design of the slot 324 and the block 325 allows the worker to quickly replace the elastic block 322 when the elastic block 322 and the protrusion 323 are worn.

[0021] Protective components 5 are installed on the opposite sides of the fixed frame 11 and the stepped frame 21. The design of the protective components 5 can limit the corrugated guardrail and prevent the corrugated guardrail from falling off the conveying mechanism 1 or the unloading mechanism 2, which could cause injury to workers.

[0022] The protective component 5 includes a protective plate 51 disposed on one side of the fixed frame 11 and the stepped frame 21. The protective plate 51 can slide up and down on one side of the fixed frame 11 and the stepped frame 21. This design makes it easier for workers to maintain the conveying mechanism 1 and the unloading mechanism 2.

[0023] A connecting frame 52 is fixedly connected to one side of the protective plate 51. A vertically arranged sliding frame 53 is slidably connected to the outside of the connecting frame 52. A spring retainer 54 for limiting the sliding of the connecting frame 52 is installed on the outside of the sliding frame 53. When the protective plate 51 needs to be moved, the protective plate 51 is pressed. At this time, the spring retainer 54 located above can be disengaged from the connecting frame 52, and the connecting frame 52 can slide inside the sliding frame 53. When the connecting frame 52 moves to the bottom, the spring retainer 54 located below can reposition the connecting frame 52.

[0024] Workflow: During the processing of the corrugated guardrail, after being compressed, it moves onto the conveyor mechanism 1. The conveyor roller 12 at the top of the fixed frame 11 provides support and guidance. When it reaches the top of the conveyor roller 12, the first electric cylinder 131 drives the electric telescopic guide rail 132 upward, causing the contact component 3 to contact the bottom of the corrugated guardrail. After the corrugated guardrail detaches from the conveyor roller 12, the electric telescopic guide rail 132 moves the corrugated guardrail above the unloading mechanism 2. Then, the first electric cylinder 131 moves downward, causing the top of the corrugated guardrail to contact the contact component 3 at the top of the second electric cylinder 23. The electric telescopic guide rail 132 can slowly return to its original position. Once the electric telescopic guide rail 132 is fully returned to its original position, the second electric cylinder 23 can descend. The corrugated guardrail can then contact the unloading roller 22 at the top of the stepped frame 21. After the second electric cylinder 23 is fully retracted, the corrugated guardrail can move on top of the stepped frame 21 under its own gravity, thus completing the unloading. The design of the conveying mechanism 1, the feeding component 13, and the unloading mechanism 2 allows for the reversible conveying of the corrugated guardrail, thereby reducing the length of the corrugated guardrail production line and making use of the space on the side of the production line. The design of the contact component 3 serves to support the corrugated guardrail. The anti-slip component 32 is designed to prevent the corrugated guardrail from sliding horizontally. When the corrugated guardrail contacts the contact block 31, the elastic block 322 at the top of the extension plate 321 can also contact the corrugated guardrail. The protrusion 323 on the top of the elastic block 322 can increase the friction, thereby preventing the corrugated guardrail from sliding. The design of the slot 324 and the block 325 allows workers to quickly replace the elastic block 322 when it is worn. The design of the stroke synchronizer 4 ensures that multiple first electric cylinders 131 and second electric cylinders 23 can move synchronously, ensuring the stability of the device operation. The protective component 5... The design can limit the corrugated guardrail to prevent it from detaching from the conveyor mechanism 1 or the unloading mechanism 2 and causing injury to workers. The design of the connecting frame 52, the sliding frame 53 and the spring retainer 54 allows the protective plate 51 to slide up and down, making it easier for workers to maintain the conveyor mechanism 1 and the unloading mechanism 2. When it is necessary to move the protective plate 51, press the protective plate 51. At this time, the spring retainer 54 located above can detach from the connecting frame 52. The connecting frame 52 can slide inside the sliding frame 53. When the connecting frame 52 moves to the bottom, the spring retainer 54 located below can reposition the connecting frame 52.
