Description

Technical Field

[0001] The utility model relates to the technical field of mechanical tools, in particular to a turning device. Background Art

[0002] For example, many H-steel profiles are used in the production of skids for oil and gas equipment. During the production process, the H-steel profiles need to be flipped to achieve a suitable angle. When flipping the H-steel profile, an open-end wrench is generally used to insert a wing plate of the H-steel profile for flipping. When the H-steel profile is flipped to a certain angle, the H-steel will continue to flip forward under the action of gravity. If the person does not let go in time, it is easy to fall or cause personal injury. It is necessary to design a tool that can easily flip the H-steel profile without causing injury to the person to solve the problems existing in the existing technology. Utility Model Content

[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] In the description of the embodiments of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connection", "interlock", etc. should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0032] The directional terms mentioned in the embodiments of the present invention, such as "upper" and "lower", etc., are only used with reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present invention, rather than indicating or implying that the devices or components referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the embodiments of the present invention.

[0033] like Figure 1-5, 7 together, a flip device provided by an embodiment of the present disclosure includes: a tool handle 1, a fixed wrench 2, and a rotating wrench 3; the fixed wrench 2 includes a groove body 21 along the up-down direction, and a flange 22 integrally provided with a first edge 23 of the groove body 21, a first stop 25 integrally provided with a second edge 24 of the groove body 21, and a second stop 26 located above the groove body 21 and integrally provided, the flange 22 is provided at the upper part of the first edge 23, and the first stop 25 is provided at the lower part of the second edge 24; the rotating wrench 3 includes a first matching portion 31, a second matching portion 32 and a root portion 33 integrally provided, the first matching portion 31, the second matching portion 32 and the root portion 33 forming a U-shaped notch 34 with an opening facing downward, and the first matching portion 31 can be embedded in the groove body 21; the lower part of the tool handle 1 is fixedly connected to the upper part of the fixed wrench 2, and the rotating wrench 3 is rotatably connected to the axis hole 5 of the flange 22 of the fixed wrench 2 through the axis hole 5 of the root portion 33 via the positioning axis 4.

[0034] The first edges 23 are the first surfaces of the two sides of the groove body 21 , and the second edges 24 are the second surfaces of the two sides of the groove body 21 . The first surface and the second surface are oppositely arranged along the depth direction of the groove body 21 .

[0035] The “integrated arrangement” of the flange 22 , the first stop 25 , the second stop 26 , the rotary wrench 3 , etc. should be understood in a broad sense. They may be integrally cast components, or the components may be connected into one through an assembled connection structure.

[0036] After the rotary wrench 3 is inserted into the groove 21 , the axial hole 5 at the root 33 of the rotary wrench 3 corresponds to the axial holes 5 on both sides of the flange 22 . After the positioning shaft 4 passes through the axial holes 5 , the rotary connection between the rotary wrench 3 and the fixed wrench 2 is achieved.

[0037] The tool handle 1 is fixedly connected to the upper part of the fixed wrench 2. The tool handle 1 can be fixedly connected to the second stop 26. For example, a bolt connection hole is provided on the second stop 26 or the tool handle 1 is directly welded to the second stop 26. No specific restrictions are made here.

[0038] This solution is achieved by setting a tool handle 1, a fixed wrench 2 and a rotating wrench 3. The fixed wrench 2 and the rotating wrench 3 are rotatably connected by a positioning shaft 4. The rotating wrench 3 is provided with a U-shaped notch 34. The U-shaped notch 34 is used to clamp the workpiece 6, and the rotating wrench 3 is configured to be partially embedded in the slot body 21 of the fixed wrench 2. When embedded and blocked by the stopper of the fixed wrench 2, the rotating wrench 3 and the fixed wrench 2 are combined into a whole and drive the workpiece 6 to flip over; when the workpiece 6 is flipped to a certain angle, the fixed wrench 2 and the rotating wrench 3 generate relative rotational motion around the positioning shaft 4, and the fixed wrench 2 gradually contacts the ground and plays a supporting role. The staff straightens the tool handle 1 with the support point as a reference. Under the action of the gravity of the workpiece 6, the rotating wrench 3 rotates with the workpiece 6 around the positioning shaft 4 until the rotating wrench 3 is blocked by the second stop 26, finally achieving the safe flipping of the workpiece 6.

[0039] like Figure 2 、 7 As shown in FIG. 9 , the surface of the first matching portion 31 located at the U-shaped notch 34 is set as a vertical surface along the up-down direction, and the surface of the second matching portion 32 located at the U-shaped notch 34 is set as a vertical surface along the up-down direction.

[0040] In the flipping state, the U-shaped groove 34 is clamped on the workpiece 6, point three 9 of the workpiece 6 forms the rotation axis point of the flipping, point one 7 of the vertical surface of the second matching part 32 forms the lifting point for applying force to the workpiece 6, and point two 8 of the vertical surface of the first matching part 31 forms a support point during the flipping process of the workpiece 6.

[0041] like Figure 1 、 4 As shown, the first edge 23 is configured as a vertical surface along the vertical direction. When the first mating portion 31 is inserted into the groove body 21, the first edge 23 and the surface of the first mating portion 31 located at the U-shaped notch 34 are coplanar in the depth direction of the groove body 21. With this arrangement, when the workpiece 6 is in the flipped state, the support provided by point 2 8 is shared by both the rotating wrench 3 and the fixed wrench 2, enhancing support rigidity.

[0042] like Figure 6 、 8 As shown, the surface of the first matching portion 31 away from the U-shaped notch 34 is set to be inclined from top to bottom toward the U-shaped notch 34, and the inclination angle is set to α2; the second edge 24 is set to be inclined from top to bottom toward the groove body 21, and the inclination angle is set to α1; α1=α2.

[0043] The first matching portion 31 and the second edge 24 are inclined at equal angles, so that the fixed wrench 2 and the rotating wrench 3 fit more tightly in the initial state of flipping, thereby ensuring the flipping effect.

[0044] like Figure 1 、 2As shown in Figures 3 and 4, the height of the second mating portion 32 is less than that of the first mating portion 31 in the vertical direction relative to the positioning axis 4, and the height of the first mating portion 31 is less than that of the trough body 21. This arrangement shortens the distance between point 1 (7) exerting the lifting force and point 2 (8) providing support, facilitating the flipping of the workpiece 6. Furthermore, because the height of the first mating portion 31 is less than that of the trough body 21, point 4 (10) of the fixed wrench 2 provides secondary support when the workpiece 6 is falling, allowing the rotating wrench 3 to rotate relative to the fixed wrench 2, ensuring that the workpiece 6 can be safely flipped and dropped to a lower position.

[0045] The above are merely specific embodiments of the present disclosure, intended to enable those skilled in the art to understand and implement the present disclosure. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present disclosure. Therefore, the present disclosure is not limited to these embodiments, but is to be construed in the broadest manner consistent with the principles and novel features disclosed herein.
