Description

Technical Field

[0001] This utility model relates to the field of maintenance device technology, and in particular to a flipping device. Background Technology

[0002] In the field of coal mine equipment technology, the maintenance of hydraulic supports is a crucial task. Side guard plates are one of the key structural components of hydraulic supports, and their maintenance requires flipping to ensure thorough and comprehensive repair. Currently, there are two main traditional methods for flipping side guard plates: First, workers place the side guard plate on the workshop floor and use an overhead crane with slings to lift it. The crane operator then adjusts the position of the trolley and gantry to shift the center of gravity of the side guard plate and achieve the flip. Second, workers use a forklift, extending the forks under the side guard plate and tilting it forward to complete the flip. However, both methods pose certain safety hazards. Misoperation of the overhead crane or forklift can lead to injury. Furthermore, both methods rely heavily on manual judgment, resulting in low efficiency and difficulty in meeting the maintenance needs of a large number of side guard plates. Utility Model Content

[0020] Compared with the prior art, the flipping device implemented in this utility model has the following advantages:

[0021] In this invention's flipping device, two supporting beams are spaced apart in the left-right direction, and their top surfaces support the side guard plate.

Furthermore, a first connecting member is slidably connected to the two supporting beams in the front-back direction. A moving component is disposed on the supporting beams and connected to the first connecting member.

[0028] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0029] In the description of this utility model, it should be understood that the terms "top", "bottom", "inner", "outer", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0031] like Figures 1 to 5As shown, a flipping device of this utility model includes a support frame 1, a flipping assembly 2, and a moving assembly 3. The support frame 1 includes two relatively fixed load-bearing beams 11, which are spaced apart in the left-right direction and extend in the front-back direction. The flipping assembly 2 includes a first connecting member 21, a first flipping member 22a, and a second flipping member 22b. The first connecting member 21 is disposed between the two load-bearing beams 11, and its two ends are slidably connected to the two load-bearing beams 11 in the front-back direction. The first flipping member 22a includes a first flipping rod 22a1 and a first driver 22a2, and the second flipping member 22b includes a second flipping rod 22b1 and a second driver 22b2. The first flipping rod 22a1 and the second flipping rod 22b1 are rotatably mounted on the first connecting member 21. The first driver 22a2 is connected to the first flipping rod 22a1 and is used to drive the first flipping rod 22a1 to rotate. The second driver 22b2 is connected to the second flipping rod 22b1 and is used to drive the second flipping rod 22b1 to rotate. The first flipping rod 22a1 and the second flipping rod 22b1 rotate simultaneously to flip the side guard plate 10. The moving component 3 is mounted on the bearing beam 11 and is connected to the first connecting member 21. The moving component 3 drives the first connecting member 21 to move in the front-back direction.

[0032] In the above technical solution, two supporting beams 11 are spaced apart in the left-right direction, and their top surfaces are used to support the side guard plate 10. At this time, one surface of the side guard plate 10 abuts against the top surface of the supporting beam 11. Furthermore, the first connecting member 21 is slidably connected to the two supporting beams 11 in the front-back direction. The moving component 3 is disposed on the supporting beam 11 and connected to the first connecting member 21. The moving component 3 can drive the first connecting member 21 to move in the front-back direction so that the first connecting member 21 moves to a suitable position to perform a flipping operation on the side guard plate 10. Furthermore, the first driver 22a2 and the second driver 22b2 respectively drive the first flipping rod 22a1 and the second flipping rod 22b1 disposed on the first connecting member 21 to rotate, so that the first flipping rod 22a1 and the second flipping rod 22b1 protrude from the top surface of the first connecting member 21. The top surface of the supporting beam 11 abuts against the two sides of the side guard plate 10, thereby clamping the side guard plate 10. The first flipping rod 22a1 and the second flipping rod 22b1 rotate simultaneously to rotate the clamped side guard plate 10. When the other side of the side guard plate 10 corresponds to or abuts against the top surface of the supporting beam 11, the flipping operation of the side guard plate 10 is completed. Then, the first flipping rod 22a1 and the second flipping rod 22b1 can rotate to below the top surface of the supporting beam 11 to avoid obstructing other operations. In summary, after supporting the side guard plate 10, the flipping device of this utility model can flip the side guard plate 10 at a suitable position. During the flipping process, the side guard plate 10 will not be in a free state. The flipping process is very stable and fast. Therefore, the flipping is highly safe and efficient.

[0033] The first driver 22a2 and the second driver 22b2 can be piston cylinders (such as pneumatic cylinders, hydraulic cylinders, and electric cylinders) or motors.

[0034] In addition, the first flipping rod 22a1 and the second flipping rod 22b1 can rotate along an axis parallel to the left and right direction.

[0035] In addition, the first connector 21 and the moving component 3 can be lower than the bottom surface of the supporting beam 11 to avoid hindering the overturning operation.

[0036] In addition, the relative positional relationship between the two load-bearing beams 11 should be fixed. The relative positional relationship between the two load-bearing beams 11 can be ensured by fixing them to the ground, or by moving component 3 or flipping component 2.

[0037] Furthermore, the first connector 21 has a first hinge portion on its front side, a second hinge portion on its rear side, and a connecting shaft 25 extending in the left-right direction on its top surface. The first flipping rod 22a1 has a third hinge portion on one side and a first flipping surface 22a11 on the opposite side. One end of the first flipping rod 22a1 is rotatably connected to the connecting shaft 25. The two ends of the first driver 22a2 are rotatably connected to the first hinge portion and the third hinge portion, respectively. The second flipping rod 22b1 has a fourth hinge portion on one side and a second flipping surface 22b11 on the opposite side. One end of the second flipping rod 22b1 is rotatably connected to the connecting shaft 25. The two ends of the second driver 22b2 are rotatably connected to the second hinge portion and the fourth hinge portion, respectively. The first driver 22a2 and the second driver 22b2 are piston cylinders. The first flipping surface 22a11 and the second flipping surface 22b11 are used to abut against the side guard plate 10.

[0038] Specifically, when the first actuator 22a2 extends, the end of the first flip rod 22a1 away from the connecting shaft 25 rises; when the first actuator 22a2 shortens, the end of the first flip rod 22a1 away from the connecting shaft 25 lowers. When the second actuator 22b2 extends, the end of the second flip rod 22b1 away from the connecting shaft 25 rises; when the second actuator 22b2 shortens, the end of the second flip rod 22b1 away from the connecting shaft 25 lowers. When the first actuator 22a2 and the second actuator 22b2 extend simultaneously, the first flip rod 22a1 and the second flip rod 22b1 clamp the side guard plate 10.

[0039] Furthermore, the flipping component 2 also includes a plurality of first flipping members 22a and a plurality of second flipping members 22b, wherein the plurality of first flipping members 22a are spaced apart from the first connecting member 21 in the left-right direction, and the plurality of second flipping members 22b are spaced apart from the first connecting member 21 in the left-right direction.

[0040] Among them, multiple flip-over components can improve the reliability of flipping and reduce the risk of unilateral displacement of the side guard plate 10.

[0041] Furthermore, the flipping assembly 2 also includes a first linkage rod 23a and a second linkage rod 23b. The first linkage rod 23a is fixedly connected to the side of each first flipping rod 22a1 that has a third hinge portion, and the second linkage rod 23b is fixedly connected to the side of each second flipping rod 22b1 that has a fourth hinge portion.

[0042] Among them, the linkage rod can ensure the synchronous rotation of each connected flip rod, further reducing the risk of unilateral displacement of the side guard plate 10.

[0043] Furthermore, the flipping assembly 2 also includes two first fixing cylinders 24, which are fixedly disposed on the first connecting member 21 and face the sides of the two supporting beams 11 respectively. The first fixing cylinders 24 are telescopic to abut against the sides of the supporting beams 11. When the first fixing cylinders 24 abut against the sides of the supporting beams 11, the first connecting member 21 is fixedly connected to the two supporting beams 11.

[0044] The first fixed cylinder 24 enables the tilting assembly 2 to be independently fixed to the bearing beam 11, rather than relying solely on the moving assembly 3 for fixation, thereby ensuring the reliability of the tilting assembly 2 during tilting operations; in addition, the first fixed cylinder 24 is a piston cylinder.

[0045] Furthermore, the first fixing cylinder 24 is located on the bottom surface of the first connecting member 21 to prevent the first fixing cylinder 24 from hindering the turning operation.

[0046] Furthermore, the moving component 3 includes a second connecting member 31 and a driving cylinder 32. The second connecting member 31 is disposed between the two supporting beams 11, and its two ends are respectively connected to the two supporting beams 11. The two ends of the driving cylinder 32 are respectively connected to the first connecting member 21 and the second connecting member 31. The driving cylinder 32 is telescopic to drive the first connecting member 21 to move in the front-back direction.

[0047] The movable component 3 is fixed to the bearing beam 11 by the second connector 31, and the first connector 21 is driven to move in the front-back direction by the drive cylinder 32, thereby flipping the side guard plate 10; in addition, the drive cylinder 32 is a piston cylinder.

[0048] Furthermore, the two ends of the second connecting member 31 are slidably connected to the two supporting beams 11 in the front-back direction, and the moving component 3 also includes two second fixing cylinders 33. The two second fixing cylinders 33 are fixedly disposed on the second connecting member 31 and face the sides of the two supporting beams 11 respectively. The second fixing cylinders 33 can extend and retract to abut against the sides of the supporting beams 11. When the second fixing cylinders 33 abut against the sides of the supporting beams 11, the second connecting member 31 is fixedly connected to the two supporting beams 11.

[0049] The sliding connection and the second fixed cylinder 33 allow the second connecting member 31 to adjust its position in the front-to-back direction on the bearing beam 11, thereby adjusting the travel of the first connecting member 21 to increase the flexibility of the flipping operation.

[0050] Furthermore, one of the supporting beams 11 has a T-shaped groove 13 extending in the front-rear direction on its side relative to the other supporting beam 11, and the two ends of the first connector 21 are respectively provided with T-shaped sliders 26, which are inserted into the T-shaped grooves 13 to connect the first connector 21 and the supporting beam 11.

[0051] Among them, both the T-shaped groove 13 and the T-shaped slider 26 are lateral T-shaped. Their connection can reduce the probability of the first connecting piece 21 and the bearing beam 11 separating, and improve the reliability of the flipping device.

[0052] Furthermore, the support frame 1 also includes multiple support feet 12, and the bottom surface of any of the bearing beams 11 is provided with multiple support feet 12 to raise the height of the bearing beams 11, thereby facilitating the placement and removal of the side guard plate 10 and the flipping operation.

[0053] Furthermore, in this embodiment, each piston cylinder should be of the same type, such as a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder, to facilitate the use of the same power source for driving and to facilitate control.

[0054] Furthermore, fixed setting and fixed connection refer to the fixed relative positional relationship of two components, including but not limited to fixing by connectors, fixing by welding, fixing by adhesive, fixing by integral molding, and fixing by snap-fit ​​connection.

[0055] Furthermore, sliding connection and sliding setting refer to the connection between two connected components, where one component can slide along a fixed trajectory on the other component, including but not limited to connection by sliding a slider into a groove, or connection by inserting a slider into a hole whose size and profile match the slider.

[0056] Furthermore, rotatable connection and rotatable setting refer to the ability of two connected components to rotate, including but not limited to connections via bearings or clearance fits.

[0057] Furthermore, the connectors include, but are not limited to, fasteners, straps, ropes, pneumatic connectors, hydraulic connectors, flanges, Velcro, and buttons.

[0058] In summary, the present invention provides a flipping device, the technical effects of which are as follows:

[0059] In this utility model's flipping device, two supporting beams 11 are spaced apart in the left-right direction, and their top surfaces are used to support the side guard plate 10. At this time, one surface of the side guard plate 10 abuts against the top surface of the supporting beam 11. Furthermore, a first connecting member 21 is slidably connected to the two supporting beams 11 in the front-back direction. A moving component 3 is disposed on the supporting beam 11 and connected to the first connecting member 21. The moving component 3 can drive the first connecting member 21 to move in the front-back direction so that the first connecting member 21 moves to a suitable position to perform the flipping operation on the side guard plate 10. Furthermore, a first driver 22a2 and a second driver 22b2 respectively drive the first flipping rod 22a1 and the second flipping rod 22b1 disposed on the first connecting member 21 to rotate, so that the first flipping rod 22a1 and the second flipping rod 22b1 convex. The first and second flipping rods 22a1 and 22b1 rotate simultaneously to rotate the clamped side guard plate 10. When the other side of the side guard plate 10 corresponds to or abuts against the top surface of the bearing beam 11, the flipping operation of the side guard plate 10 is completed. Then, the first and second flipping rods 22a1 and 22b1 can rotate to below the top surface of the bearing beam 11 to avoid obstructing other operations. In summary, after bearing the side guard plate 10, the flipping device of this utility model can flip the side guard plate 10 at a suitable position. During the flipping process, the side guard plate 10 will not be in a free state. The flipping process is very stable and fast. Therefore, the flipping is safe and efficient.

[0060] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
