Description

Technical Field

[0001] This utility model relates to the field of supporting technology for steel bar production, and in particular to a protective device for preventing flying steel in a steel bar production line. Background Technology

[0002] In steel bar production lines, the looper is a critical piece of equipment in the continuous rolling process, used to coordinate the rolling rhythm between different stands, buffer the tension of the rolled piece, and ensure stable production. However, in actual production, steel pile-up accidents can easily occur due to factors such as bent head of the rolled piece, damaged guide device, improper mill speed matching, or abnormalities in the looper itself. After steel pile-up occurs, the high-speed, high-temperature rolled piece flies out of the looper area due to loss of control, forming a "flying steel" phenomenon.

[0003] Because steel pile-up accidents are sudden and random, and the rolling speed in the finishing rolling zone is extremely high, the direction and landing point of the high-temperature rolled pieces that fly out are difficult to predict and control, posing a serious threat to the personal safety of production line operators. At the same time, they are prone to impacting and burning surrounding electromechanical equipment and infrastructure, causing production interruption and property damage.

[0004] Currently, to solve this problem, companies mainly rely on strengthening production process control, such as optimizing rolling procedures, increasing equipment inspection frequency, and strengthening operation training, to reduce the probability of steel piling. However, such measures can only reduce the frequency of accidents and cannot fundamentally eliminate the safety hazards caused by steel flying after piling. Once an accident occurs, there is still a risk of personal injury and equipment damage, and the safety risk is high. Utility Model Content

[0005] In view of the above-mentioned problems that existing methods cannot fundamentally eliminate the safety hazards caused by steel flying after steel stacking, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a looper anti-splashing protection device in a steel bar production line, which aims to effectively restrain high-temperature rolled pieces and prevent them from splashing when a steel stacking accident occurs.

[0007] To solve the above technical problems, this utility model provides the following technical solution: a looper anti-flying steel protection device in a steel bar production line, including a looper device, an anti-flying steel cover is detachably installed in the middle of the top of the looper device, and a material inlet is provided on both the front and rear faces of the anti-flying steel cover, and an observation window is hinged inside the material inlet.

[0008] The anti-fly shield has elastic snap-fit ​​components installed on one side of both the front and back sides. The movable end of the elastic snap-fit ​​component is fixed with a snap rod. The end of the observation window near the elastic snap-fit ​​component is welded with a snap seat. One side of the snap seat has a snap hole for engaging with the snap rod.

[0009] As an improved technical solution, the elastic snap-fit ​​assembly includes a fixing block welded to the anti-flying shield, a T-shaped rod slidably mounted on the fixing block through a sliding hole thereon, and a translation block welded to one end of the T-shaped rod near the mounting base.

[0010] As an improved technical solution, a spring is sleeved on the rod portion of the T-shaped rod between the opposite surfaces of the fixed block and the translation block, and a buckle frame is welded to the end of the T-shaped rod away from the translation block.

[0011] As an improved technical solution, two guide rods are welded to one end face of the fixed block near the translation block, and two positioning holes are opened on one side of the translation block for the guide rods to pass through.

[0012] As an improved technical solution, a smooth rod bolt is welded to each of the four corners of the top of the looper, and a limiting hole for the smooth rod bolt to pass through is opened at each of the four corners of the top of the anti-flying cover. A hexagonal nut is threaded onto the threaded end of the smooth rod bolt.

[0013] As an improved technical solution, two lifting lugs are welded to both sides of the top of the anti-flying shield, and the lifting lugs are provided with round holes.

[0014] As an improved technical solution, the observation window has a perforated block welded to the end face away from the anti-fly shield, and a hanging hole is provided at the top of the perforated block.

[0015] After adopting the above technical solution, the beneficial effects of this utility model are:

[0016] 1. This utility model involves installing a hexagonal nut on the threaded part of the smooth rod bolt, pressing the hexagonal nut onto the top of the anti-flying shield, and fixing the anti-flying shield to the looper. The original looper does not need to be modified; only the anti-flying shield needs to be added to its upper part. The looper and the anti-flying shield are fixed by threads. Its structure is simple, easy to manufacture and assemble, and very convenient to use.

[0017] 2. This utility model fixes the observation window inside the material inlet, preventing it from being opened by flying steel impacts, thus improving the stability of the protection. The opening and closing of the observation window can be achieved by hooking the buckle frame or the hole block, avoiding close contact between the anti-flying steel cover and the observation window, which helps prevent burns and improves the safety of opening and closing the observation window.

[0018] 3. This utility model, by adding an anti-scraping cover to the looper, completely covers the rolled piece inside the looper in the event of a steel pile-up accident, eliminating personnel and equipment accidents caused by flying steel. This greatly improves the safety factor of operators, equipment, and facilities, effectively enhancing safety. At the same time, it does not require modification of the existing looper structure; the functional upgrade is achieved simply by adding the anti-scraping cover. It is easy to install, low in cost, and easy to promote and apply. Furthermore, the elastic locking component controls the locking of the locking rod and the locking seat, allowing for quick opening and closing of the observation window. Opening the observation window allows for the handling of steel piles inside the looper, making operation convenient. Attached Figure Description

Detailed Implementation

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Example 1

[0027] Reference Figures 1-3This is the first embodiment of the present utility model, which provides a looper anti-flying steel protection device in a steel bar production line. This looper anti-flying steel protection device in a steel bar production line includes a looper device 1. The looper device 1 is an existing mature device and will not be described in detail. An anti-flying steel cover 2 is detachably installed in the middle of the top of the looper device 1. The front end and rear end of the anti-flying steel cover 2 are provided with material inlet 3. An observation window 4 is hinged inside the material inlet 3 and a rectangular cavity is provided on the observation window 4.

[0028] The anti-flying shield 2 has elastic snap-fit ​​components 5 installed on one side of both the front and back sides. The movable end of the elastic snap-fit ​​component 5 is fixed with a snap rod 13. The observation window 4 is welded with a snap seat 11 at one end near the elastic snap-fit ​​component 5. A snap hole 12 is opened on one side of the snap seat 11 to engage with the snap rod 13.

[0029] The elastic snap-fit ​​assembly 5 includes a fixing block 51 welded to the anti-flying shield 2. A T-shaped rod 57 is slidably installed on the fixing block 51 through a sliding hole. A translation block 54 is welded to one end of the T-shaped rod 57 near the card seat 11, and the locking rod 13 is welded to the translation block 54.

[0030] A spring 53 is sleeved on the rod part of the T-shaped rod 57 between the opposite surfaces of the fixed block 51 and the translation block 54. A buckle frame 52 is welded to the end of the T-shaped rod 57 away from the translation block 54. The observation window 4 can be opened and closed by hooking the buckle frame 52 or the hole block 10. This avoids the staff from touching the anti-fly shield 2 and the observation window 4 at close range, which helps to prevent burns and improves the safety of opening and closing the observation window 4.

[0031] Two guide rods 56 are welded to one end face of the fixed block 51 near the translation block 54, and two positioning holes 55 are opened on one side of the translation block 54 for the guide rods 56 to pass through.

[0032] During use, by adding an anti-flying steel cover 2 to the looper 1, the rolled piece is completely covered inside the looper 1 in the event of a steel pile-up accident, eliminating personnel and equipment accidents caused by flying steel. This greatly improves the safety factor of operators, equipment, and facilities, effectively enhancing safety. At the same time, there is no need to modify the existing structure of the looper 1; the function is upgraded simply by adding the anti-flying steel cover 2. The installation is convenient, the cost is low, and it is easy to promote and apply. Furthermore, the elastic snap-fit ​​component 5 controls the snap-fit ​​between the snap-fit ​​rod 13 and the snap-fit ​​seat 11, allowing for quick opening and closing of the observation window 4. Opening the observation window 4 allows for the handling of the steel pile inside the looper 1, making operation convenient.

[0033] Example 2

[0034] Reference Figures 1-2This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: a smooth rod bolt 6 is welded to each of the four corners of the top of the loose-fitting device 1, and a limiting hole 8 is opened at each of the four corners of the top of the anti-flying shield 2 for the smooth rod bolt 6 to pass through. A hexagonal nut 7 is threaded onto the threaded end of the smooth rod bolt 6. When the four smooth rod bolts 6 pass through the limiting hole 8, the installation position of the anti-flying shield 2 is limited, so as to prevent the anti-flying shield 2 from being in a movable state when it is fixed, and also to improve the accuracy of the installation position of the anti-flying shield 2.

[0035] Two lifting lugs 9 are welded to both sides of the top of the anti-flying shield 2, and the lifting lugs 9 are provided with round holes.

[0036] The observation window 4 is welded with a hole block 10 on the end face away from the anti-flying shield 2, and the top of the hole block 10 is provided with a hanging hole. If the hook rod is hooked on the hole block 10, the observation window 4 can be pulled out from the inside of the material outlet 3.

[0037] During use, the smooth rod bolt 6 passes through the inside of the limiting hole 8, and the hexagonal nut 7 is installed on the threaded part of the smooth rod bolt 6. The hexagonal nut 7 is pressed on the top of the anti-flying cover 2, thus fixing the anti-flying cover 2 to the looper 1. The original looper 1 does not need to be modified; only the anti-flying cover 2 needs to be added to its upper part. The looper 1 and the anti-flying cover 2 are fixed by threads. Its structure is simple, easy to manufacture and assemble, and very convenient to use.

[0038] Based on embodiments 1-2, the working principle of this utility model is as follows: The process of installing the anti-flying shield 2 on the looper 1 is as follows: Weld the smooth rod bolts 6 at the four corners of the top of the looper 1. When installing the anti-flying shield 2 on the looper 1, make the smooth rod bolts 6 pass through the inside of the limiting hole 8.

[0039] Subsequently, the hexagonal nut 7 is installed on the threaded part of the smooth rod bolt 6, and the anti-flying cover 2 is fixed to the loose-loop device 1 by pressing the hexagonal nut 7 on the top of the anti-flying cover 2.

[0040] By hanging the hook rod on the buckle frame 52 and working towards the side away from the card seat 11, the pulling force causes the card rod 13 to disengage from the inside of the card seat 11, and the translation block 54 compresses the spring 53. At this time, the card rod 13 is disengaged from the card seat 11, and the observation window 4 can be opened and closed.

[0041] When the observation window 4 is closed, the tension applied to the buckle frame 52 is released. Under the elastic action of the spring 53, the locking rod 13 self-resets and enters the inside of the locking hole 12 to lock, thereby fixing the observation window 4 inside the material inlet 3, preventing the observation window 4 from being opened by flying steel, improving the stability of the protection, and controlling the opening and closing of the observation window 4.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
