Description

Technical Field

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

[0002] There are many types of flipping devices. According to the volume size, they can be divided into large, medium and small types. Generally, large flipping devices are used more in steel enterprises, mainly for 90° flipping of rolling mills or flipping of parts that need to be flipped before installation. Medium or small flipping devices are rarely seen in steel enterprises, but they 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 90° before maintenance and installation.

[0003] Guide guards must be used during the rolling of rolling mills in the rolling production line of steel enterprises. Its function is to help the rolled pieces 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 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 guards are large, they cannot be carried by manpower or it takes a lot of manpower to carry them. 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 is needed for flipping operations. In any case, on-site personnel must participate and perform operations such as straightening the guide guard during the flipping process. There are great safety hazards during the flipping process.

[0004] To avoid the occurrence of safety hazards, steel enterprises generally use existing flipping devices. However, the existing flipping devices use a large number of link mechanisms. When the number of components is large, large cumulative motion errors will occur, thus reducing the motion accuracy. In addition, the flipping efficiency is relatively low and the inertial force generated during the movement of the flipping device is difficult to balance, and there is a hidden danger of jamming the flipping device. Therefore, it is necessary to specifically design a special flipping device. Content of the Utility Model

Detailed implementation manners

[0034] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to be able to fully convey the scope of the present invention to those skilled in the art.

[0035] As Figure 1 and Figure 2 shown, the present invention provides a flipping device, and the flipping device includes:

[0036] Frame 1;

[0037] Two flipping platforms 2, one end of the two flipping platforms 2 is connected to each other, one end of the two flipping platforms 2 is hingedly connected to the frame 1, a set angle is provided between one side of the two flipping platforms 2, and one side of one of the two flipping platforms 2 or the other side is used to set the components to be flipped;

[0038] The first rod body 3 and the second rod body 4, one end of the first rod body 3 and one end of the second rod body 4 are respectively hinged to the other side of two flipping platforms 2, and the other end of the first rod body 3 is hinged to the other end of the second rod body 4;

[0039] The telescopic driving member 5, one end of the telescopic driving member 5 is hinged to the frame 1, and the other end of the telescopic driving member 5 is hinged to the first rod body 3 or the second rod body 4. The two flipping platforms 2 can flip the parts to be flipped when the telescopic driving member 5 drives the first rod body 3 and the second rod body 4 to rotate.

[0040] Specifically, to solve the problems that the existing flipping device is relatively complex, has many components, has flipping errors, relatively low flipping efficiency, difficult to balance inertial force, and flipping jamming, the present utility model provides a flipping device. One end of each of the two flipping platforms 2 of the flipping device is hinged to the frame 1. One end of the first rod body 3 and one end of the second rod body 4 are respectively hinged to the other side of the two flipping platforms 2, and the other end of the first rod body 3 is hinged to the other end of the second rod body 4. The two flipping platforms 2 can flip the parts to be flipped when the telescopic driving member 5 drives the first rod body 3 and the second rod body 4 to rotate, and can flip the parts to be flipped from one side of one of the two flipping platforms 2 to the other side. The flipping device can achieve flipping transmission by using the transmission of the first rod body 3 and the second rod body 4, and can easily complete the flipping action, avoiding using more link mechanisms for flipping, improving the flipping accuracy and flipping efficiency, and not easily occurring flipping jamming phenomenon. At the same time, the flipping device uses the cooperation of the two flipping platforms 2, the first rod body 3 and the second rod body 4 for flipping, balances the inertial force, and improves the stability of the flipping device during flipping. Since the components used in the flipping device are also relatively few and the weight is relatively light, it can be arbitrarily set to the set position according to the usage situation, which is very convenient.

[0041] Preferably, the set angle between one side of the two flipping platforms 2 is 90 degrees, and the other side of the two flipping platforms 2 can respectively abut against the top of the frame 1.

[0042] Specifically, when one of the flipping platforms 2 is in a horizontal state, the other flipping platform 2 is in a vertical state. The parts to be flipped are hoisted onto the flipping platform 2 in the horizontal state by a lifting tool. By starting the telescopic driving member 5, the parts that cannot be flipped by manpower or hoisting can be flipped by 90°, and the 90-degree stable flipping of the parts can be realized.

[0043] Preferably, the flipping device includes two connecting plates 6. The two connecting plates 6 are respectively connected to both sides of one end of one of the flipping platforms 2, the two connecting plates 6 are respectively connected to both sides of one end of the other flipping platform 2, and the two connecting plates 6 are respectively hinged to both sides of the top of the frame 1.

[0044] Specifically, the connecting plate 6 is used to connect the two turning platforms 2, and the connecting plate 6 can be welded to the turning platform 2.

[0045] Preferably, the turning device further includes at least two buffer rubber blocks 7. At least one buffer rubber block 7 is provided at both ends of the top of the frame 1, and the other ends of the two turning platforms 2 can respectively fit on the buffer rubber blocks 7 at both ends.

[0046] Specifically, the buffer rubber block 7 can buffer the turning platform 2 to prevent the turning platform 2 from impacting the bracket 1. The buffer rubber block 6 can be installed on the frame 1 by gluing or bolts.

[0047] Preferably, the first hinge point 8 between one end of the first rod body 3 and one of the turning platforms 2, the second hinge point 9 between one end of the second rod body 4 and the other turning platform 2, the third hinge point 10 between the other end of the first rod body 3 and the other end of the second rod body 4, the fourth hinge point 11 between one end of the telescopic driving member 5 and the frame 1, and the fifth hinge point 12 between the other end of the telescopic driving member 5 and the first rod body 3 or the second rod body 4 are all connected by a pin shaft 14. The sixth hinge point 13 between one end of the two turning platforms 2 and the frame 1 is all connected by a rotating shaft 19.

[0048] Specifically, the pin shaft is used to realize the hinge connection of each hinge point.

[0049] As Figure 3 shown, preferably, the pin shaft 14 includes:

[0050] A screw rod 15, with a pin hole provided at one end of the screw rod 15;

[0051] A nut 16, threadedly connected to the screw rod 15;

[0052] A gasket 17, sleeved on the screw rod 15;

[0053] A split pin 18, inserted into the pin hole, and the nut 16 is arranged between the split pin and the gasket 17.

[0054] Specifically, the cooperation of the nut 16 and the gasket 17 is used to prevent the lateral movement and radial rotation of the screw rod 15, avoiding large cumulative errors. The errors existing in the working process of the linkage mechanism may cause excessive stress at a certain hinge point of the linkage mechanism, resulting in wear of the screw rod 15 or the pin hole. Therefore, such a design is made. On the one hand, it is easy to replace. On the other hand, since the rotation speed of each hinge point is slow, the pin shaft 14 is allowed to have a certain rotation.

[0055] As Figure 4As shown, preferably, the distance between the first hinge point 8 and the sixth hinge point 13 is greater than one half of the distance between the other end of one of the turning platforms 2 and the sixth hinge point 13, and the distance between the second hinge point 9 and the sixth hinge point 13 is greater than one half of the distance between the other end of the other turning platform 2 and the sixth hinge point 13.

[0056] Specifically, with respect to the sixth hinge point 13, in order to enable the first hinge point 8 and the second hinge point 9 to obtain a greater torque under the action of the telescopic driving member 5 and make it easier for the two turning platforms 2 connected at a right angle to rotate, the distance L1 between the first hinge point 8 and the sixth hinge point 13 is greater than one half of the distance L between the other end of one of the turning platforms 2 and the sixth hinge point 13, and the distance L1 between the second hinge point 9 and the sixth hinge point 13 is greater than one half of the distance L between the other end of the other turning platform 2 and the sixth hinge point 13, that is, L1 > L / 2.

[0057] As Figure 5 shown, preferably, the eccentric angle of the telescopic driving member 5 is greater than 0 degrees or less than 30 degrees.

[0058] Specifically, the first hinge point 8, the second hinge point 9, the third hinge point 10, and the fifth hinge point 12 are all on a circle with the sixth hinge point 13 as the center. In order to ensure that the two turning platforms 2 connected at a right angle have a certain starting torque, it is necessary to ensure a certain eccentric distance a between the fifth hinge point 12 and the fourth hinge point 11 in the design. At the same time, it is also necessary to ensure that the eccentric angle θ of the telescopic driving member 5 is greater than 0 degrees or less than 30 degrees, that is, 0° < θ < 30°. The position of the telescopic driving member 5 is suitable and reasonable to avoid jamming or inability to achieve the turning function during work.

[0059] Preferably, the telescopic driving member 5 is a hydraulic driving member, a pneumatic driving member, or an electric driving member.

[0060] Specifically, when the telescopic driving member 5 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.

[0061] Preferably, the inside of the frame 1 is provided with a space for the first rod 3 and the second rod 4 to rotate, and the top of the frame 1 is provided with a frame opening for the first rod 3 and the second rod 4 to rotate.

[0062] The frame 1 is a truss structure and can be welded with square tubes or steel sections, etc. The turning platform 2 can also be made or welded with square tubes, steel sections, and steel plates. The height of the frame 1 can be designed according to ergonomics, and the operator does not need to climb a ladder or squat down to operate.

[0063] In summary, when the flipping device of the present utility model is implemented, the components to be flipped are lifted by a sling to the flipping table 2 in a horizontal state. By activating the telescopic driving member 5, components that cannot be flipped manually or by lifting can be flipped by 90°. A smooth 90-degree flipping of the components can be achieved. The components can be flipped from one side of one of the two flipping tables 2 to the other side. The flipping device can achieve flipping transmission by using the transmission of the first rod body 3 and the second rod body 4, and it is very easy to complete the flipping action, avoiding the use of more link mechanisms for flipping, improving the flipping accuracy and efficiency, and not easily getting stuck during flipping. At the same time, the flipping device uses the cooperation of two flipping tables 2, the first rod body 3 and the second rod body 4 that are connected at right angles to balance the inertial force and improve the stability of the flipping device during flipping. Since the components used in the flipping device are relatively few and light in weight, it can be arbitrarily set to the set position according to the usage situation, which is very convenient.

[0064] The various embodiments of the present utility model have been described above. 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.
