Description

Technical Field

[0001] The utility model belongs to the technical field of hot-rolled strip steel hoisting equipment, and in particular relates to an automatic righting bracket of a C-shaped hook used for a crane in hot-rolled strip steel hoisting. Background Art

[0002] In the production process of hot-rolled strip steel, the overhead crane is the main equipment for lifting and transportation. Its main function is to accurately transport the strip steel coils that have just completed the hot rolling process and have a temperature of up to 600-700℃ from the production line to the designated storage location. However, the C-type hook part of the existing overhead crane equipment lacks an automatic adjustment structure, which makes it impossible to directly and accurately insert it into the inner core of the finished strip steel coil during the lifting process. This not only seriously affects the lifting efficiency, but also may cause safety hazards during the lifting process, such as the strip steel coil slipping or tilting, which poses a huge threat to the stable operation of the production line.

[0003] In response to the above-mentioned problems, the current measure is to rely on manual straightening of the C-type hook operation. However, this practice has many safety hazards. First, the crane operators must work in a high temperature environment, which not only brings a huge physical burden to the crane operators, but also may cause a series of health problems, such as heat stroke and skin burns. Second, operation in a high temperature environment increases the risk of operating errors, which may lead to accidents during the lifting process, thereby affecting production efficiency and product quality. Third, long-term high-temperature operations may also cause irreversible damage to the health of the crane operators, further increasing the pressure on the company's labor safety and health management.

[0004] Therefore, in view of the shortcomings of the crane hook design in the hot-rolled strip production process, it is urgent to design a solution that can automatically adjust the hook direction, reduce manual intervention, and ensure the safety of the crane workers' working environment. This solution not only needs to be able to achieve automatic positioning and precise lifting of the hook to improve production efficiency and product quality, but also has important significance for the sustainable development of hot-rolled strip production. Utility Model Content

[0005] Aiming at the fact that there are many problems in the process of overhead crane hoisting steel coils due to the lack of automatic adjustment structure of C-type hook part in the background technology, the utility model provides an automatic straightening bracket of C-type hook of overhead crane used in hot-rolled strip hoisting.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an automatic straightening bracket of a C-type hook used in the lifting of hot-rolled strip steel by an overhead crane, comprising a base plate and a front baffle vertically fixed thereon, the front baffle being provided with a V-shaped opening, and the two sides of the base plate being connected to the front baffle by side wing plates respectively, and side baffles being obliquely arranged on both sides of the base plate by support plates respectively, the inner surfaces of the two side baffles being flush with the two oblique sides of the V-shaped opening, and being arranged in an outward eight-shaped shape, a straightening baffle and a guide frame being arranged on the side baffle on one side, the guide frame being located above the straightening baffle, and during the translation of the C-type hook toward the straightening baffle, its inclined end first contacts the straightening baffle and then continues to translate so that the C-type hook gradually tends to be parallel to the straightening baffle, and the straightened C-type hook is lifted upward, and under the guidance and expansion of the guide frame, its two hook claws are respectively slid and inserted into the inner core of the finished strip steel coil.

[0007] As a further supplement to the above technical solution, a roller is arranged on the straightening baffle, which is used to reduce the friction between the C-type hook and the straightening baffle during the upward lifting process.

[0008] As a further supplement to the above technical solution, protective covers are respectively provided on both sides of the straightening baffle to protect the supporting bearing components of the roller conveyor from being damaged by the impact of the C-type hook, thereby affecting the normal use of the roller conveyor.

[0009] As a further explanation and limitation of the above technical solution, the guide frame includes two vertical poles respectively fixed on the side baffles, and arc-shaped guide rods and expansion rods are respectively arranged on both sides of the two poles, a longitudinal connecting rod is fixed between the vertical pole and the lower end of the arc-shaped guide rod on the same side, a lower transverse connecting rod is fixed between the two arc-shaped guide rods, and an upper transverse connecting rod is fixed between the two vertical poles, and the longitudinal connecting rod, the lower transverse connecting rod and the upper transverse connecting rod are jointly used to ensure the stability of the overall structure of the guide frame.

[0010] As a further supplementary explanation of the above technical solution, each of the longitudinal connecting rods is connected to the side baffle through a lower oblique support rod, and the two lower oblique support rods are used to enhance the overall connection strength of the guide frame.

[0011] As a further supplement to the above technical solution, the righting baffle is hinged on the side baffle, and two shock-absorbing arms are hinged between the two. The two shock-absorbing arms are used to ensure that the side baffle is in a vertical state while absorbing the impact energy generated by the collision of the C-type hook, thereby preventing the C-type hook from being damaged due to direct impact with the righting baffle.

[0012] Compared with the prior art, the utility model has the following advantages:

[0013] 1. The utility model adds a straightening baffle and a guide frame to the side baffle. During the travel of the overhead crane, the C-shaped hook moves horizontally toward the straightening baffle. Its inclined end first contacts the straightening baffle and then continues to move horizontally, eventually making the C-shaped hook gradually parallel to the straightening baffle. The straightened C-shaped hook is lifted upward and under the guidance and expansion of the guide frame, its two hook claws slide and insert into the inner core of the finished strip steel coil. Therefore, the utility model can greatly reduce the intervention of the overhead crane operator in straightening and improve the efficiency of hoisting. At the same time, since no one is required to participate in the straightening process, the risk of safety accidents caused by improper operation is also reduced.

[0014] 2. The utility model introduces rollers into the righting baffle to reduce the friction between the C-type hook and the righting baffle, and uses the shock-absorbing arm to absorb the impact energy generated by the collision, which effectively protects the equipment and prolongs its service life. This indirectly reduces the maintenance cost of the enterprise and improves the economic benefits.

[0015] 3. The utility model adopts the structural design of the guide frame, in which the arc-shaped guide rod and the expansion rod cooperate to ensure that the C-type hook always maintains a stable direction and posture during the lifting process. This not only improves the lifting accuracy, but also ensures the stability of the finished strip steel coil during the lifting process, avoiding quality problems and safety hazards caused by unstable lifting.

[0016] 4. The design of the utility model has certain versatility and flexibility, and can adapt to C-type hooks of different specifications and sizes and finished strip steel coils. At the same time, through simple structural adjustment and combination, it can also realize the selection of multiple lifting methods, which enhances its adaptability and flexibility in practical applications. This not only meets the actual needs of hot-rolled strip lifting, but also promotes the technological progress and development in the field of overhead crane lifting.

[0025] In order to further illustrate the technical solution of the utility model, the following Figures 1 to 6 ,According to the on-site transformation implementation situation, we further illustrate the utility model through two embodiments. Embodiment 1

[0026] As attached Figures 1 to 4 As shown, an automatic righting bracket of a C-type hook in hot-rolled strip lifting is used for a overhead crane, comprising a base plate 1 and a front baffle plate 2 vertically fixed thereon, a V-shaped opening 3 is opened on the front baffle plate 2, and the base plate 1 is connected to the front baffle plate 2 via side wing plates 4 on both sides, and side baffle plates 5 are obliquely arranged on both sides of the base plate 1 via support plates 6, the inner surfaces of the two side baffle plates 5 are flush with the two oblique sides of the V-shaped opening 3, and are arranged in an outward eight-shaped shape, and a righting baffle plate 7 and a guide frame 8 are arranged on one side of the side baffle plate 5, and the guide frame 8 is located above the righting baffle plate 7. The guide frame 8 includes two vertical poles 801, an arc-shaped guide rod 802, and an expansion rod 803. The two vertical poles 801 are respectively fixed on the side baffle 5, and the arc-shaped guide rod 802 and the expansion rod 803 are distributed on both sides of the vertical pole 801. A longitudinal connecting rod 804 is fixed between the vertical pole 801 and the lower end of the arc-shaped guide rod 802 on the same side. Each of the longitudinal connecting rods 804 is connected to the side baffle 5 through a lower diagonal support rod 805 to enhance the overall connection strength of the guide frame 8; a lower transverse connecting rod 806 is fixed between the two arc-shaped guide rods 802, and an upper transverse connecting rod 807 is fixed between the two vertical poles 801. The longitudinal connecting rod 804, the lower transverse connecting rod 806 and the upper transverse connecting rod 807 are used together to ensure the stability of the overall structure of the guide frame 8. Embodiment 2

[0027] Since the C-type hook strikes the righting baffle during the righting process, the direction righting adjustment is achieved by using the single-point contact translation method of the C-type hook, and the C-type hook forms hard contact friction with the righting baffle during the lifting process. Therefore, in actual use, it is inevitable that the C-type hook will be damaged due to impact or hard contact friction, or even the righting baffle will be deformed and damaged.

[0028] Based on the above embodiment 1, as shown in the attached Figure 2 As shown, we take two corresponding measures for the above two situations: First, a roller 9 is provided on the righting baffle 7, and protective covers 10 are provided on both sides of the righting baffle 7 to protect the supporting bearing components of the roller 9 from being damaged by the impact of the C-type hook 12, thereby affecting the normal use of the roller 9. The design of the roller 9 can effectively reduce the friction between the C-type hook 12 and the righting baffle 7 during the upward lifting process. Second, the righting baffle 7 is hinged to the side baffle 5, and two shock absorbing arms 11 are hinged between the two. The two shock absorbing arms 11 are used to ensure that the side baffle 5 is in a vertical state while absorbing the impact energy generated by the impact of the C-type hook 12, so as to avoid the C-type hook 12 from being damaged by directly hitting the righting baffle 7.

[0029] Its working principle: as shown in the attached Figures 4 to 6 As shown, the crane operator drives the crane to translate toward the straightening baffle 7. At this time, the inclined end of the C-shaped hook 12 first contacts the straightening baffle 7, and the crane continues to translate so that the C-shaped hook 12 gradually tends to be parallel with the straightening baffle 7. The straightened C-shaped hook 12 is lifted upward and slides smoothly on the roller table 9, and is guided by two arc-shaped guide rods 802 in turn to the two expansion rods 803. Then the crane operator drives the crane to continue to translate along the expansion rods 803, and the two claws of the C-shaped hook 12 expand during the translation process. Finally, the two claws slide to the two ends of the finished strip steel coil respectively, and the crane operator adjusts the position of the C-shaped hook 12 until it is inserted into the inner core of the finished strip steel coil.

[0030] From the perspective of technological advancement, this solution has the following significant advantages:

[0031] 1. Ingenious structural design: The design of the automatic righting bracket makes full use of the mechanical principles and mechanical structure, so that the C-type hook can automatically adjust its direction during the hoisting process to achieve the righting function. In particular, through the combination of the V-shaped opening, side baffles, righting baffles and guide frames, the C-type hook is effectively guided and righted, improving the hoisting efficiency.

[0032] 2. Innovative application: rollers are installed on the righting baffle, which significantly reduces the friction of the C-type hook during the lifting process and prolongs the service life of the equipment. At the same time, the design of the shock-absorbing arm effectively absorbs the impact energy generated by the impact of the C-type hook and avoids damage to the equipment.

[0033] 3. Easy to implement and maintain: The solution has a clear structure and strong connections between components, which is convenient for on-site installation and commissioning. At the same time, due to the modular design, maintenance and replacement of components become simple and quick, reducing maintenance costs.

[0034] 4. Strong adaptability: This technical solution is suitable for C-type hooks of different specifications and sizes, showing good versatility and adaptability. In addition, through simple adjustments, this solution can also be applied to other similar lifting scenarios, expanding the scope of application.

[0035] 5. High safety: The entire design process takes into account the safety and stability of the equipment, and multiple protection and support measures are used to ensure safety during the lifting process.

[0036] In summary, this technical solution has a high degree of technical advancement in the automatic straightening of C-type hooks in the lifting of hot-rolled strip steel. It not only improves the lifting efficiency, but also enhances the safety and stability of the equipment, providing strong technical support for the production of hot-rolled strip steel. At the same time, the innovation and practicality of this solution also provide new ideas and methods for the design of lifting equipment in similar scenarios.
