DETAILED DESCRIPTION
[0030] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative work fall within the scope of protection of the present application.
[0031] In the description of the present application, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise" and the like indicate the orientation or positional relationship shown in the drawings, and are only used to facilitate the description of the present application and simplify the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.
[0032] The present application provides a turning device which can be used for turning a long-shaped special-shaped pipe mold, and does not need to be provided with a driving motor and a transmission component, and has a relatively simple structure and a relatively low cost. It should be noted that the turning device can also be applied to other products which are inconvenient to be directly turned, and is not limited herein.
[0033] As Figure 1 And Figure 2As shown, the overturning device comprises at least two rolling structures 100, each of which is provided with a limiting hole 110 for the to-be-overturned member 20 to pass through. In this way, the at least two rolling structures 100 are arranged at intervals along the length direction of the to-be-overturned member 20, and the to-be-overturned member 20 passes through the limiting hole 110 of each rolling structure 100, and then only needs to be manually pushed to roll, so as to realize the overturning of the to-be-overturned member 20. It needs to be explained that, as the name implies, the rolling structure 100 can roll on the ground or workbench, so that the manual pushing of the rolling structure 100 can realize the rolling of the rolling structure 100. As an example, the orthographic projection of the rolling structure 100 on the plane perpendicular to the length direction of the to-be-overturned member 20 is circular, so as to realize the rolling of the rolling structure 100.
[0034] In other embodiments, as shown in Figure 3 In the plane perpendicular to the length direction of the to-be-overturned member 20, the outer edge shape of the orthographic projection of the rolling structure 100 can also comprise an arc and a straight line connected to both ends of the arc, the arc-shaped part of the rolling structure 100 is an arc surface, and the straight line part is a plane; the setting of the arc surface can realize the overturning of the to-be-overturned member 20 by 180°, and the setting of the plane can avoid the rolling of the rolling structure 100 during transportation by contacting with the supporting surface during transportation.
[0035] In addition, it needs to be explained that the number of rolling structures 100 is usually two, which can be sleeved from both ends of the to-be-overturned member 20. When the length of the to-be-overturned member 20 is longer, more rolling structures 100 can also be arranged, which is not limited herein. Of course, the number of rolling structures 100 is preferably two.
[0036] Please refer to Figure 4 and Figure 5 In one embodiment, the overturning device further comprises a positioning assembly 200 arranged on the rolling structure 100, and the positioning assembly 200 comprises a positioning block 210 movably arranged relative to the rolling structure 100. The positioning block 210 can be docked and separated from the to-be-overturned member 20 during movement, so as to fix the to-be-overturned member 20 relative to the rolling structure 100 when docked with the to-be-overturned member 20, thereby avoiding damage to the to-be-overturned member 20 due to shaking during overturning, and also improving the accuracy of overturning.
[0037] It needs to be explained that the limiting hole 110 on the rolling structure 100 is roughly the same as the cross-sectional shape of the to-be-tilted piece 20, and has a certain limiting effect on the to-be-tilted piece 20, but if directly tilted, the to-be-tilted piece 20 will still have a large swing in the limiting hole 110, that is, the to-be-tilted piece 20 will collide with the rolling structure 100 during the tilting process. At the same time, since the size and weight of the to-be-tilted piece 20 are usually large, if the to-be-tilted piece 20 is not fixed relative to the rolling structure 100, the collision between the two will easily cause damage to the to-be-tilted piece 20 or the rolling structure 100, which is dangerous; in addition, the force generated by the swing will also be transmitted to the rolling structure 100, which will make the rolling of the rolling structure 100 inconvenient to control, that is, the tilting angle of the to-be-tilted piece 20 is inconvenient to control.
[0038] Further, the tilting device further comprises a locking assembly 300, the locking assembly 300 is arranged on the rolling structure 100, and the locking assembly 300 comprises a locking piece 310 movably arranged relative to the rolling structure 100, and the locking piece 310 can pass through a locking position and a release position during movement.
[0039] When the locking piece 310 is located at the locking position and the positioning block 210 is in abutment with the to-be-tilted piece 20, the locking piece 310 can lock the positioning block 210, so that the positioning block 210 remains in abutment with the to-be-tilted piece 20, avoiding the to-be-tilted piece 20 from swinging during tilting; when the locking piece 310 is located at the release position, the positioning block 210 can be in abutment with and separated from the to-be-tilted piece 20. As can be seen, during tilting, the positioning block 210 can be locked by the locking piece 310, so that the positioning block 210 remains in abutment with the to-be-tilted piece 20, thereby fixing the to-be-tilted piece 20 and avoiding the to-be-tilted piece 20 from swinging.
[0040] In order to facilitate understanding of the principle of the above-mentioned tilting device, the working process of the tilting device in the above-mentioned embodiment will be described in combination with Figure 1 The working process of the tilting device in the above-mentioned embodiment will be described in combination with two rolling structures 100 as an example:
[0041] First, the to-be-tilted piece 20 is lifted, then the two rolling structures 100 are sleeved from both ends of the to-be-tilted piece 20, that is, the to-be-tilted piece 20 is arranged in the limiting holes 110 of the two rolling structures 100; next, the positioning block 210 is brought into abutment with the to-be-tilted piece 20, and then the locking piece 310 is moved to the locking position to lock the positioning block 210. After the to-be-tilted piece 20 is fixed relative to the rolling structure 100, the to-be-tilted piece 20 can be lowered, and the lowered to-be-tilted piece 20 is supported by the rolling structure 100. Next, the rolling structure 100 is pushed to roll, so that the to-be-tilted piece 20 is tilted, after the tilting is completed, the to-be-tilted piece 20 is lifted again, the locking piece 310 is moved to the release position, the positioning block 210 is separated from the to-be-tilted piece 20, and finally the rolling structure 100 is removed from the to-be-tilted piece 20.
[0042] With the turnover device, the at least two rolling structures 100 are sleeved on the turnover part 20, then the positioning part is butted against the turnover part 20 to fix the turnover part 20 relative to the rolling structure 100, at the same time, the locking part 310 is moved to the locking position to lock the positioning part, then the rolling structure 100 is pushed to roll, and the turnover of the turnover part 20 is realized. Since the rolling structure 100 can be rolled by manual pushing, it is not necessary to set a driving structure and transmission components, the structure is simplified, and the equipment cost is reduced. At the same time, the turnover part 20 is fixed relative to the rolling structure 100 by the cooperation of the positioning part and the locking part 310, the shaking of the turnover part 20 in the turnover process is avoided, the damage of the turnover part 20 and the rolling structure 100 is avoided, and the safety of the turnover is improved.
[0043] In addition, compared with directly turning over the turnover part 20 by manual, the turnover device can reduce the turnover difficulty, facilitate the turnover of the turnover part 20, and improve the safety in the turnover process.
[0044] In one embodiment, the number of the positioning assembly 200 and the locking assembly 300 is multiple, and the positioning assembly 200 and the locking assembly 300 are arranged on each rolling structure 100 to ensure that the turnover part 20 is kept stable relative to each rolling structure 100 in the turnover process. Of course, when the number of the rolling structure 100 is greater than two or in other cases, the positioning assembly 200 and the locking assembly 300 can be arranged on part of the rolling structure 100.
[0045] Please refer to Figure 4 and Figure 5 In one embodiment, the rolling structure 100 comprises a first annular plate 120, a second annular plate 130 and a plurality of fixing parts 140, the first annular plate 120 and the second annular plate 130 are coaxially arranged and have the same size, and the plurality of fixing parts 140 are connected with the first annular plate 120 and the second annular plate 130 to fix the first annular plate 120 and the second annular plate 130. By arranging two annular plates, the stability of the support and rolling can be improved. It can be understood that the limiting holes 110 corresponding to each other are arranged on the first annular plate 120 and the second annular plate 130, so that the turnover part 20 can pass through the rolling structure 100, and the rolling structure 100 is sleeved on the turnover part 20.
[0046] In actual application, the positioning block 210 is arranged on the side of the first annular plate 120 away from the second annular plate 130, and is arranged to be reciprocally movable along the radial direction of the first annular plate 120; the locking member 310 is arranged on the second annular plate 130 and is arranged to be reciprocally movable along the axial direction of the second annular plate 130, and during the movement, one end of the locking member 310 can pass through the first annular plate 120 and extend to the side of the first annular plate 120 away from the second annular plate 130, so as to realize locking and releasing of the positioning block 210.
[0047] Please refer to Figure 4 In one embodiment, the positioning assembly 200 further comprises a mounting base 220, a positioning connecting rod 230 and a first reset member 240. The mounting base 220 is arranged on the rolling structure 100, and is arranged on the side of the first annular plate 120 away from the second annular plate 130. The positioning connecting rod 230 is connected to the mounting base 220 to be reciprocally movable along the length direction of the positioning connecting rod 230, i.e. to be reciprocally movable along the radial direction of the first annular plate 120. The positioning block 210 is connected to one end of the positioning connecting rod 230, so as to be reciprocally movable along the radial direction of the first annular plate 120. The first reset member 240 is connected to the rolling structure 100 and the positioning block 210, so as to drive the positioning block 210 to separate from the turnover part 20.
[0048] Therefore, when it is needed to fix the turnover part 20, the operator needs to apply an external force to the positioning connecting rod 230 or the positioning block 210, so that the positioning block 210 moves to be in abutment with the turnover part 20 against the force of the first reset member 240, and then the positioning block 210 is locked by the locking member 310. After the locking member 310 is moved to the releasing position, the positioning block 210 separates from the turnover part 20 under the action of the first reset member 240. Preferably, the first reset member 240 is a tension spring.
[0049] In addition, it needs to be noted that in the present embodiment, the turnover part 20 is provided with a protrusion 21, and the side of the positioning block 210 facing the turnover part 20 is provided with a groove 211. The abutment between the positioning block 210 and the turnover part 20 refers to the abutment between the groove 211 and the protrusion 21, so as to fix the turnover part 20 after the abutment is completed. In order to avoid damage to the surface of the turnover part 20 or to improve the positioning strength, a flexible anti-skid pad can be arranged on the inner wall of the groove 211.
[0050] Further, when the locking member 310 is located at the locking position and the positioning block 210 is in abutment with the turnover part 20, the locking member 310 can abut against the end of the positioning connecting rod 230 away from the positioning block 210, so as to lock the positioning block 210, and make the positioning block 210 remain at the position in abutment with the turnover part 20.
[0051] As an example, the mounting base 220 is provided with a guide hole, which penetrates the mounting base 220 along the radial direction of the first annular plate 120, and the positioning connecting rod 230 is slidably arranged in the guide hole and extends out of the guide hole at both ends.
[0052] Please refer to Figure 4 and Figure 5 In one embodiment, the locking assembly 300 further comprises a second reset member 320, which is arranged between the rolling structure 100 and the locking member 310 to drive the locking member 310 to move from the release position to the locking position. Therefore, the locking member 310 has a tendency to move to the locking position without external intervention. When it is needed to separate the positioning block 210 from the to-be-flipped part 20, an external force is first applied to make the locking member 310 move to the release position against the force of the second reset member 320, and then the positioning block 210 is separated from the to-be-flipped part 20; at the same time, when it is needed to fix the to-be-flipped part 20, the positioning block 210 is butted against the to-be-flipped part 20, and then the external force on the locking member 310 is removed, so that the locking member 310 can move to the locking position under the action of the second reset member 320 to lock the positioning block 210.
[0053] Preferably, the second reset member 320 is a compression spring. Please refer to Figure 4 and Figure 5 , Figure 4 In the locking position of the locking member 310 in Figure 5 , the locking member 310 is in the release position, and in this embodiment, the locking assembly 300 further comprises an abutting plate 330, which is arranged on the locking member 310 and located between the first annular plate 120 and the second annular plate 130; the second reset member 320 is arranged between the first annular plate 120 and the second annular plate 130, and one end of the second reset member 320 abuts against the second annular plate 130, and the other end abuts against the abutting plate 330, thereby pushing the locking member 310 to move to the locking position.
[0054] Please refer to Figure 6 In one embodiment, the locking assembly 300 further comprises a guide sleeve 340, which is arranged on the rolling structure 100 and specifically arranged on the second annular plate 130, and the guide sleeve 340 extends along the axial direction of the second annular plate 130, and the locking member 310 is axially reciprocally arranged in the guide sleeve 340.
[0055] Further, the locking member 310 can also rotate, i.e. self-rotate in the guide sleeve 340. The locking assembly 300 further comprises a limiting post 350 fixedly connected to the locking member 310. The sidewall of the guide sleeve 340 is provided with a first limiting groove 341, a guide groove 342 and a second limiting groove 343. The guide groove 342 extends along the axial direction of the guide sleeve 340. The first limiting groove 341 and the second limiting groove 343 respectively communicate with two ends of the guide groove 342, and both the first limiting groove 341 and the second limiting groove 343 extend along the circumferential direction of the guide sleeve 340. The limiting post 350 is movable in the first limiting groove 341, the guide groove 342 and the second limiting groove 343.
[0056] Herein Figure 6 is described: Figure 6 The locking member 310 is located at the releasing position, and the second reset member 320 can provide an acting force for moving the locking member 310 to the right. At this time, the limiting post 350 is located in the first limiting groove 341, so as to limit the movement of the locking member 310 to the right. The locking member 310 and the limiting post 350 are rotated, so that the limiting post 350 enters the guide groove 342. Under the action of the second reset member 320, the locking member 310 and the limiting post 350 move to the right and stop at the end of the guide groove 342. At this time, the locking member 310 moves to the locking position. Next, the locking member 310 is rotated, and the limiting post 350 enters the second limiting groove 343, so as to limit the locking member 310 at the locking position. It can be understood that, in other embodiments, the second limiting groove 343 can not be provided. After the limiting post 350 moves to the end of the guide groove 342, the movement of the limiting post 350 stops, and the locking member 310 is kept at the locking position under the action of the second reset member 320. Of course, the provision of the second limiting groove 343 can ensure that the locking member 310 is kept at the locking position during the overturning process, thereby improving the reliability.
[0057] Specifically Figure 6 to the embodiment shown in the drawings, the first limiting groove 341 is located at the end of the guide sleeve 340, and the end of the guide groove 342 communicating with the first limiting groove 341 penetrates the end of the guide sleeve 340. Similarly, it can be understood that the first limiting groove 341 can not be provided. After the limiting post 350 moves out of the guide groove 342, the limiting post 350 is rotated, and then abuts against the end of the guide sleeve 340 under the action of the second reset member 320. Of course, the provision of the first limiting groove 341 can improve the reliability of the device, so as to avoid the limiting post 350 from entering the guide groove 342 due to vibration or other factors.
[0058] Please refer to Figure 1 and Figure 5 In an embodiment, the overturning device further comprises a handle 410. The handle 410 is arranged on the rolling structure 100 and at least partially protrudes out of the rolling structure 100, so as to facilitate an operator to hold and push the rolling structure 100 to roll through the handle 410.
[0059] Further, the overturning device further comprises a sleeve 420 arranged on the rolling structure 100, and specifically arranged on the side of the first annular plate 120 away from the second annular plate 130. The handle 410 is movably arranged in the sleeve 420 along the length direction of the sleeve 420, so as to extend and retract the sleeve 420 during movement. As can be known from the above description, the handle 410 extending out of the sleeve 420 can also extend out of the rolling structure 100, so as to facilitate holding when extending out, and facilitate transportation and storage of the overturning device when retracting into the sleeve 420. In addition, as shown in Figure 1 , the extended handle 410 can be supported on the ground or a workbench, so as to fix the overturning device and the workpiece 20 to be overturned, and avoid rolling.
[0060] In order to facilitate understanding of the technical solutions of the present application, the working process of the overturning device in the above embodiment is described in combination with Figure 1 , Figure 4 and Figure 5 .
[0061] As shown in Figure 5 , the locking member 310 is located at the release position. The workpiece 20 to be overturned is hoisted, and then the two rolling structures 100 are sleeved on the two ends of the workpiece 20. Next, an external force is applied to the positioning block 210, so that the positioning block 210 moves towards the workpiece 20 and is in abutment with the workpiece 20. The external force on the positioning block 210 is maintained, and then the locking member 310 is rotated, so that the limiting column 350 corresponds to the guide groove 342. The locking member 310 is moved to the locking position under the action of the second reset member 320, and then the locking member 310 is rotated, so that the limiting column 350 enters the second limiting groove 343. The external force on the positioning block 210 is removed, and the positioning connecting rod 230 abuts against the locking member 310, as shown in Figure 4 .
[0062] After the workpiece 20 to be overturned is fixed relative to the rolling structure 100, the handle 410 is pulled out of the sleeve 420, and the rolling structure 100 is placed on the workbench. Next, the operator pushes the rolling structure 100 to roll by holding the handle 410, until the workpiece 20 to be overturned is overturned by a preset angle. The workpiece 20 to be overturned is hoisted again, the locking member 310 is rotated, so that the limiting column 350 enters the guide groove 342, and then the locking member 310 is pulled to move to the release position, and the limiting column 350 enters the first limiting groove 341.
