Description

Technical Field

[0001] The utility model belongs to the technical field of flipping, and more specifically, relates to a flipping mechanism. Background Art

[0002] There are many types of flipping mechanisms. According to the volume size, they can be divided into large, medium and small types. Generally, large flipping mechanisms are used more in steel enterprises, mainly for flipping the rolling mill by 90° or flipping the parts that need to be installed after flipping. However, medium or small flipping mechanisms are rarely seen in steel enterprises, but medium or small flipping mechanisms are very common in other occasions, and there are also many structural types. Since there are many parts with not very large volume in steel enterprises, especially the guide guards need to be flipped by 90° before they can be overhauled and installed.

[0003] During the rolling of the rolling mill in the rolling production line of steel enterprises, guide guards must be used. The function is to help the rolled piece enter and exit the roll pass accurately and stably in a given direction and state during the rolling process. Some guide guards need to be flipped by 90° during use or maintenance. Determined by the on-site production conditions, when the rolling production line of steel enterprises produces large-sized bars or profiles, relatively larger guide guards need to be used. When the weight and volume of the guide guard are large, it is impossible to carry it manually or it requires a lot of manpower. The traditional method is the most primitive and simplest and crudest flipping method, directly using a crowbar to flip the guide guard. If the volume and quality of the guide guard are relatively large, using a crowbar is ineffective, and a crane needs to be used for flipping operations. In any case, on-site personnel must participate, and the guide guard needs to be straightened or other operations during the flipping process, and there are great safety hazards during the flipping process.

[0004] As Figure 1 shown, to avoid the occurrence of safety hazards, steel enterprises generally use existing flipping mechanisms. However, the existing flipping mechanisms use a large number of link mechanisms. The flipping disk 8 is connected to the base 9 through the link mechanism. There are gaps in the lower pairs of the link mechanism, and large cumulative motion errors will occur when the number of components is large, thus reducing the motion accuracy. In addition, the flipping efficiency is relatively low and the inertial force generated during the movement of the flipping mechanism is difficult to balance, and there is a hidden danger of jamming the flipping mechanism. Therefore, it is necessary to specifically design a special flipping mechanism. Summary of the Utility Model

[0005] The purpose of the utility model is to address the deficiencies of the existing technologies and provide a flipping mechanism to solve the problems of the existing flipping mechanism being relatively complex, having many components, having flipping errors, relatively low flipping efficiency, difficult to balance inertial force, and flipping jamming as mentioned in the above background art.

[0006] To achieve the above object, the present utility model provides a flipping mechanism, which includes:

On the contrary, these embodiments are provided so that the present invention will be more thorough and complete, and can fully convey the scope of the present invention to those skilled in the art.

[0031] As Figures 2 - 4 shown, the present invention provides a flipping mechanism, which includes:

[0032] Frame 1;

[0033] Two plate frames 2, one end of the two plate frames 2 is connected to each other, one end of the two plate frames 2 is hinged to the frame 1, a set angle is provided between one side of the two plate frames 2, and one side of one of the two plate frames 2 or the other side is used to set the parts to be flipped;

[0036] Specifically, to solve the problems that the existing flipping mechanism is relatively complex with many components, there are flipping errors, low flipping efficiency, difficult balance of inertial force, and flipping jamming, the present utility model provides a flipping mechanism.

The two plate frames 2 of this flipping mechanism can flip the component to be flipped when the telescopic driving member 4 drives the rod body 1 to rotate, and can flip the component to be flipped from one side of one of the two plate frames 2 to the other side. This flipping mechanism can achieve flipping transmission using an arc-shaped rod body 3, easily complete the flipping action, avoid using multiple link mechanisms for flipping, improve the flipping accuracy and efficiency, and there will be no flipping jamming phenomenon. At the same time, this flipping mechanism uses the cooperation of two plate frames 2 and the rod body 3 for flipping, balances the inertial force, and improves the stability of the flipping mechanism during flipping. Since the components used in this flipping mechanism are also relatively few and light in weight, it can be arbitrarily set to the set position according to the usage situation, which is very convenient.

[0037] Preferably, the set angle between one side of the two plate frames 2 is 90 degrees, and the other sides of the two plate frames 2 can respectively abut against the top of the frame 1.

[0038] Specifically, when one of the plate frames 2 is in a horizontal state, the other plate frame 2 is in a vertical state. The component to be flipped is lifted by a sling onto the plate frame 2 in the horizontal state. By starting the telescopic driving member 4, the component that cannot be flipped by manpower or by lifting can be flipped by 90°, and a smooth 90-degree flipping of the component can be achieved.

[0039] Preferably, the flipping mechanism includes two connecting plates 5. The two connecting plates 5 are respectively connected to both sides of one end of one of the plate frames 2, the two connecting plates 5 are respectively connected to both sides of one end of the other plate frame 2, and the two connecting plates 5 are respectively hingedly connected to both sides of the top of the frame 1.

[0040] Specifically, the connecting plate 5 is used to connect the two plate frames 2, and the connecting plate 5 can be welded to the plate frame 2.

[0041] Preferably, the flipping mechanism further includes two buffer rubber blocks 6. The two buffer rubber blocks 6 are respectively connected to both ends of the top of the frame 1, and the other ends of the two plate frames 2 can respectively fit on the two buffer rubber blocks 6.

[0043] Preferably, the rod body 3 includes a first rod body and a second rod body, and the first rod body and the second rod body are arranged at intervals.

[0044] Specifically, the telescopic driving member 4 can move between the first rod body and the second rod body, avoiding interference between the telescopic driving member 4 and the rod body 3 during the circular motion of the rod body 3.

[0045] Preferably, one end of the telescopic driving member 4 is hinged between the first rod body and the second rod body, and the other end of the telescopic driving member 4 is hinged to the bottom end of the frame 1. The distance between the first rod body and the second rod body is greater than the diameter of the telescopic driving member 4.

[0046] Specifically, the distance between the first rod body and the second rod body is greater than the diameter of the telescopic driving member 4, avoiding interference between the telescopic driving member 4 and the rod body 3 during the circular motion of the rod body 3.

[0047] Preferably, one end of the telescopic driving member 4 can be hinged to the inner arc surface or the outer arc surface of the rod body through a bracket.

[0048] Preferably, the flipping mechanism includes two rib plates 7, each rib plate 7 is connected to the first rod body and the second rod body, and the two rib plates 7 are respectively arranged close to the two plate frames 2.

[0049] Specifically, to ensure sufficient strength and stiffness, the first rod body and the second rod body are welded into a whole through the rib plates 7.

[0050] As Figure 5 shown, preferably, a first hinge point 8 is provided between one end of the rod body 3 and one of the plate frames 2, a second hinge point 9 is provided between the other end of the rod body 3 and the other plate frame 2, and a third hinge point 10 is provided between the other end of the telescopic driving member 4 and the rod body 3. When the first hinge point 8 is on a horizontal straight line, the second hinge point 9 and the third hinge point 10 are on the same vertical straight line.

[0051] Specifically, a fourth hinge point 11 is provided on the connecting plate 5. The arc-shaped rod body 3 is a circular rod body. The circular rod body takes the fourth hinge point 11 as the center of the circle, and both the first hinge point 8 and the second hinge point 9 are on the circle with the fourth hinge point 11 as the center of the circle. When working, the telescopic driving member 4 drives the rod body 3, so that the rod body 3 and the plate frame 2 make a circular motion with the fourth hinge point 11 as the center of the circle, and thus the components can be flipped by 90 degrees.

[0052] When the first hinge point 8 is on a horizontal straight line, the second hinge point 9 and the third hinge point 10 are on the same vertical straight line, which can provide the maximum turning moment relative to the second hinge point 9, enabling the two plate frames 2 to rotate smoothly and reliably.

[0053] For the movement of this flipping mechanism, the second hinge point 9 is the active point and the first hinge point 8 is the driven point.

[0054] Preferably, the telescopic driving member 4 is a hydraulic driving member, a pneumatic driving member or an electric driving member.

[0055] Specifically, when the telescopic driving member 4 is a hydraulic driving member, an oil tank, a control valve and a switch can be designed and installed at appropriate positions on the frame 1.

[0056] Preferably, a space for the rod body 3 to rotate is provided inside the frame 1, and a frame opening for the rod body to rotate is provided at the top of the frame 1.

[0057] Specifically, the frame 1 is a truss structure and can be welded with square tubes or section steels, etc. The plate frame 2 can also be made or welded with square tubes, section steels and steel plates. The height of the frame 1 can be designed according to ergonomics, and the operator at the post does not need to climb a ladder or squat down for operation.

[0058] In summary, when the flipping mechanism of the present utility model is implemented, the components to be flipped are hoisted onto the plate frame 2 in a horizontal state through a sling, and the telescopic driving member 4 is started. The rod body 3 and the plate frame 2 make a circular motion with the fourth hinge point 11 as the center, and the components that cannot be flipped manually or by hoisting can be flipped by 90°. The components can be flipped from one side of one of the two plate frames 2 to the other side. The flipping mechanism can achieve flipping transmission with an arc-shaped rod body 3, and it is very easy to complete the flipping action. It avoids using multiple link mechanisms for flipping, improves the flipping accuracy and efficiency, and there will be no flipping jamming phenomenon. At the same time, the flipping mechanism uses the cooperation of two plate frames 2 and the rod body 3 connected at 90 degrees to flip, balances the inertial force, and improves the stability of the flipping mechanism during flipping. Since the components used in the flipping mechanism are relatively few and light in weight, they can be arbitrarily set to the set positions according to the usage conditions, which is very convenient.

[0059] The above has described the embodiments of the present utility model. The above description is exemplary and not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations are obvious to those of ordinary skill in the art in the technical field without departing from the scope and spirit of the described embodiments.
