Description

Technical Field

[0001] This utility model relates to the field of storage rack technology, and in particular to a detachable curved tube storage rack. Background Technology

[0002] Pipe bends are divided into plastic bends and metal bends. Plastic bends can be bent by heating the plastic section during the bending process. Metal bends, on the other hand, require special bending tools to bend.

[0003] After production, common bends are usually stacked together. When in use, because the bends are stacked together, they need to be separated before they can be picked up. In addition, when transporting the bends, the stacked bends need to be placed back onto the conveyor vehicle, which is time-consuming and labor-intensive.

[0004] A pipe bending processing transfer and storage device, disclosed in patent application CN214349185U, includes a support frame, two diagonal rods fixed to the support frame, and a stop bar fixed to the diagonal rods. The two diagonal rods are spaced apart, with the maximum distance between them less than the transverse length of the bent pipe. The sidewalls of the two diagonal rods away from the support frame are on the same plane, and one end of the sidewall away from the support frame of the diagonal rod slopes downward. The stop bar is located at the lowest end of the diagonal rod. This storage device places the higher end of the diagonal rod at the previous process and the lower end at the next process. After the previous process is completed, the bent pipe is placed on the diagonal rod, and it can slide along the diagonal rod to the next process, realizing the transfer and temporary storage of the bent pipe between two processes. However, this storage device can only be used for storing one type of bent pipe. When using this storage device for right-angled arc bends or U-shaped bends, it is easy to cause the bent pipe to shake, resulting in wear. Utility Model Content

[0033] The present invention will now be described in detail with reference to the accompanying drawings and embodiments:

[0034] like Figures 1 to 9 As shown, this utility model provides a detachable bent pipe storage rack, including two support frame plates 1. A first support rod 2 and two second support rods 3 are arranged between the two support frame plates 1. The two second support rods 3 are located below the first support rod 2 and are arranged in parallel. The first support rod 2 and the two second support rods 3 are arranged in a triangle. The two second support rods 3 can move in an arc on the support frame plate 1 to adjust the distance between the first support rod 2 and the second support rod 3. A pulley 6 is installed below the support frame plate 1. The pulley 6 is a universal pulley with a self-locking function.

[0035] In the above scheme, in the initial state, the first support rod 2 and the two second support rods 3 form an isosceles triangle, and the maximum angle between the first support rod 2 and the two second support rods 3 can be 120 degrees. When placing a small U-shaped bend (i.e., a small-diameter bend), the two second support rods 3 are rotated upwards simultaneously, reducing the distance between the second support rods 3 and the first support rod 2, thus making the angle between the two second support rods 3 and the first support rod 2 smaller (e.g., ...). Figure 10 As shown), at this time, the two second support rods 3 and the first support rod 2 are arranged in an isosceles triangle. The small U-shaped bend is placed between the second support rod 3 and the first support rod 2, so that the arc segment of the small U-shaped bend stops against the other second support rod 3. The small U-shaped bends on both sides of the first support rod 2 are staggered.

[0036] When placing a large U-shaped bend (i.e., a bend with a large diameter), the distance between the second support rods 3 and the first support rod 2 can be increased by simultaneously rotating the two second support rods 3 downwards. This method can thus define the position of the large U-shaped bend. Furthermore, by simultaneously rotating the two second support rods 3, the distance between the two second support rods 3 and the first support rod 2 can be made compatible with the inner diameter of the large U-shaped bend (e.g., ...). Figure 12As shown), the large U-shaped bend is placed between the second support rod 3 and the first support rod 2, so that the inner diameter of the arc segment of the large U-shaped bend contacts the first support rod 2. The large U-shaped bend is located between the two second support rods 3, and adjacent large U-shaped bends can be spaced apart.

[0037] When placing the right-angle bend, adjust the distance between the second support rod 3 and the first support rod 2 so that the distance between them is greater than the length of the horizontal section of the right-angle bend. Place the right-angle bend between the second support rod 3 and the first support rod 2. Due to the weight of the right-angle bend, the center of its arc segment will be located in the middle between the second support rod 3 and the first support rod 2, causing the two ends of the right-angle bend to be inclined relative to the first support rod 2 and the second support rod 3, respectively (e.g., Figure 11 As shown in the figure, this allows for the placement of right-angle bends, wherein adjacent right-angle bends can be spaced apart.

[0038] The two rotating arms 13 can be controlled independently, so that the two second support rods 3 are positioned one above the other, allowing right-angle bends and small U-shaped bends to be placed on both sides of the first support rod 2 respectively, thus enabling the storage of different types of right-angle bends and U-shaped bends.

[0039] An adjustment groove 11 is provided in the upper center of the support plate 1. The two ends of the first support rod 2 are respectively located in the adjustment grooves 11 on the two support plates 1. The two ends of the first support rod 2 are provided with threaded sections. The two ends of the first support rod 2 are fixed to the support plate 1 by nuts 21 and threaded sections. The adjustment groove 11 can adjust the position and height of the first support rod 2. After adjustment, the first support rod 2 is fixed to the support plate 1 by nuts 21. The length of the first support rod 2 is greater than the two ends of the second support rod 3. The length of the second support rod 3 is adapted to the distance between the two support plates 1.

[0040] In the above scheme, two second support rods 3 are located between two support frame plates 1. The two ends of the first support rod 2 are fixed to the support frame plate 1 by the length of the second support rod 3 and the nut 21. The two support frame plates 1 are fixed together by two second support rods 3 and one first support rod 2, thereby realizing a detachable connection between the two support frame plates 1, the two second support rods 3 and the first support rod 2, so as to reduce the area occupied by the storage rack when it is not in use.

[0041] Two support plates 1 have circular grooves 12 on their opposite sides. Two rotating arms 13 are symmetrically arranged inside the circular grooves 12. The opposite ends of the two rotating arms 13 have positioning holes 131. There is a gap between the rotating arms 13 and the circular grooves 12. The two ends of the second support rod 3 are respectively located in the two positioning holes 131 on the two support plates 1. Both ends of the second support rod 3 are provided with mounting plates 31. The mounting plates 31 are located between the rotating arms 13 and the circular grooves 12 to limit the position of the two second support rods 3. The side of the mounting plates 31 facing the circular grooves 12 is provided with ball bearings to reduce the friction between the mounting plates 31 and the circular grooves 12. The opposite ends of the support plates 1 and the support plates 1 are respectively provided with drive units for rotating the rotating arms 13. The two drive units can control the rotation of the two second support rods 3 independently. The first support rod 2 and the second support rod 3 are provided with several limiting rubber rings 5 ​​to facilitate the placement of the bent pipes at intervals and avoid friction between the pipes.

[0042] The two rotating arms 13 have several semi-circularly arranged racks 132 at their opposite ends, and the racks 132 on the two rotating arms 13 mesh with each other.

[0043] In the above scheme, after one of the rotating arms 13 rotates, the two rotating arms 13 will rotate synchronously due to the meshing action between the racks 132 on the two rotating arms 13, so as to ensure the consistency of rotation between the two rotating arms 13.

[0044] like Figures 5 to 7 As shown, the drive unit includes a rotating rod 14 and a rotating sleeve 15. One end of the rotating rod 14 passes through the support frame plate 1, is located in the circular groove 12, and is connected to the rotating arm 13. The rotating sleeve 15 is located on the outside of the support frame plate 1 and is sleeved on the rotating rod 14. The rotating sleeve 15 can slide along the left and right direction of the support frame plate 1. The rotating rod 14 and the support frame plate 1 are rotatably connected by a bearing.

[0045] The rotating rod 14 includes a rotating shaft 141 and a rectangular rod 142. The rotating arm 13 is fixedly connected to the rotating shaft 141. The rectangular rod 142 is located inside the rotating sleeve 15 and is adapted to the internal cavity of the rotating sleeve 15. The outer end of the rotating sleeve 15 is provided with a pressure plate 151. The outer side of the pressure plate 151 is provided with a hexagonal groove 153 to facilitate the use of external tools by the operator to rotate the rotating sleeve 15. The circumferential direction of the pressure plate 151 is provided with a positioning protrusion 152. The outer side of the support frame plate 1 is provided with a stepped hole 16. The outer end of the stepped hole 16 is provided with a positioning ring 161. The 151 has a positioning groove opposite to the positioning protrusion 152. The positioning protrusion 152 and the positioning groove cooperate to limit the position of the rotating sleeve 15 and prevent the rotating sleeve 15 from rotating. The inner end of the rotating sleeve 15 is provided with a limiting ring 154. The limiting ring 154 is provided to prevent the rotating sleeve 15 from disengaging from the stepped hole 16. An elastic element 17 is provided between the pressure plate 151 and the large diameter of the stepped hole 16. The elastic element 17 is a spring and is sleeved on the rotating sleeve 15. The diameter of the limiting ring 154 is larger than the inner diameter of the positioning ring 161 to achieve the outer side of the rotating sleeve 15.

[0046] In the above scheme, pressing the rotating sleeve 15 causes the positioning protrusion 152 on the rotating sleeve 15 to separate from the positioning ring 161, thus removing the constraint on the rotating sleeve 15 and causing the rotating sleeve 15 to rotate. Under the action of the rectangular rod 142, the rotating sleeve 15 drives the rotating arm 13 on the rotating shaft 141 to rotate through the rectangular rod 142, so that the rotating arm 13 rotates around the rotating shaft 141 as the center, thereby realizing the adjustment of the position of the rotating arm 13.

[0047] like Figure 1 , Figure 2 and Figure 8 As shown, a cover plate 4 is provided at the open end of the circular groove 12. The cover plate 4 can close the circular groove 12 and shield the components inside the circular groove 12. Guide slides 41 are provided on both the left and right sides of the cover plate 4. The second support rod 3 is located in the guide slide 41. A groove 43 corresponding to the adjustment groove 11 is provided on the top of the cover plate 4. Two positioning posts 42 are fixedly connected to the inner side of the cover plate 4 and are arranged in the vertical direction of the cover plate 4. The inner wall of the circular groove 12 is provided with threaded holes 121 corresponding to the positioning posts 42. The positioning posts 42 are inserted into the threaded holes 121 and the cover plate 4 is fixed in the circular groove 12 of the support frame plate 1 by bolts. After the positioning posts 42 are aligned with the threaded holes 121, bolts are screwed through the positioning posts 42 into the threaded holes 121, thereby fixing the cover plate 4 to the support frame plate 1.

[0048] The working principle of this utility model:

[0049] An external tool is inserted into the hexagonal groove 153 of the rotating sleeve 15 and pressed down, causing the rotating sleeve 15 to enter the stepped hole 16, thereby separating the rotating sleeve 15 from the positioning ring 161 and releasing the position limitation of the rotating sleeve 15. At this time, the elastic element 17 is compressed by force. Then the rotating sleeve 15 is rotated, and the rotating sleeve 15 drives the rotating arm 13 to rotate to the appropriate position. After the rotating sleeve 15 is released, the rotating sleeve 15 is reset under the action of the elastic element 17 and corresponds to the positioning groove on the positioning ring 161 again, thereby limiting the position of the rotating sleeve 15.

[0050] When placing a small U-shaped bend (i.e., a bend with a small diameter), the two second support rods 3 rotate upwards simultaneously, causing the angle between the two second support rods 3 and the first support rod 2 to decrease (e.g., ...). Figure 10 As shown, the small U-shaped bend is placed between the second support rod 3 and the first support rod 2, so that the arc segment of the small U-shaped bend abuts against the other second support rod 3, thereby limiting the position of the small U-shaped bend;

[0051] When placing a large U-shaped bend (i.e., a bend with a large diameter), the position of the large U-shaped bend can be defined by simultaneously rotating the two second support rods 3 downwards. Additionally, by simultaneously rotating the two second support rods 3, the large U-shaped bend is placed between the second support rod 3 and the first support rod 2, so that the inner diameter of the arc segment of the large U-shaped bend contacts the first support rod 2 (e.g., ...). Figure 12 As shown), the large U-shaped bend is located between the two second support rods 3, thereby limiting the position of the large U-shaped bend;

[0052] When placing the right-angle bend, adjust the distance between the second support rod 3 and the first support rod 2 so that the distance between them is greater than the length of the horizontal section of the right-angle bend. Place the right-angle bend between the second support rod 3 and the first support rod 2, so that the two ends of the right-angle bend are inclined (e.g., Figure 11 As shown in the figure, this allows for the placement of right-angle bends, thereby limiting the position of the right-angle bends.
