Description

Technical Field

[0001] This application relates to the field of marine piping system installation and maintenance technology, and in particular to an adjustable spacing gantry bracket height adjustment device. Background Technology

[0002] In the complex process of shipbuilding, the first step is for cranes to precisely lift pipes from the storage area to the designated installation location. Once the pipes arrive at their position, workers quickly erect temporary supports to provide support for subsequent steps. The pipes are then roughly placed in place, and to ensure the accuracy and stability of the piping system, workers need to pull and position them. This ensures the pipes are placed in the ideal position to meet design requirements and shipbuilding standards. Finally, once the pipes are pulled and positioned, they are spot-welded to secure them, ensuring the weld quality meets requirements and thus guaranteeing the safety and reliability of the entire piping system.

[0003] Regarding the aforementioned technologies, the inventors believe that using this solution to install pipes makes it difficult to avoid damaging the paint on the pipe surface, requires significant manual labor during installation, and results in low work efficiency. Summary of the Invention

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0028] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0029] This application discloses an adjustable-spacing portal frame height adjustment device. (Refer to...) Figure 1 , Figure 2 An adjustable spacing gantry bracket height adjustment device includes two columns 1 arranged opposite each other, a hanger 2 horizontally arranged between the two columns 1, and a lifting component 3 that drives the hanger 2 to move up and down is arranged inside the column 1. A locking component 4 is arranged at the bottom of the column 1 relative to the lifting component 3. The locking component 4 can lock the drive of the lifting component 3, so that the hanger 2 can stop at any time during the lifting process.

[0030] A base 11 is provided at the top and bottom of the column 1. The base 11 is a disc-shaped structure and is coaxially arranged with the column 1 and fixedly connected. A rib plate 12 is fixedly connected to the side wall of the column 1 at a position relative to the base 11. Four rib plates 12 are equidistantly arranged along the side wall of the column 1 and are fixedly connected to the base 11.

[0031] Reference Figure 2 , Figure 3 The column 1 includes a first column 13 at the bottom, a second column 14 at the top, and a replacement column 15 located between the first column 13 and the second column 14. The length of the replacement column 15 can be changed according to different needs to adapt to different usage scenarios.

[0032] The bottom end of the second column 14 is fixedly connected to the second insertion rod 141. The top wall of the replacement column 15 is vertically provided with a replacement insertion hole 151 at the position of the second insertion rod 141, and a replacement transverse hole 152 is horizontally provided on the side wall of the replacement insertion hole 151. A replacement rod 153 is horizontally inserted inside the replacement transverse hole 152. The second insertion rod 141 is horizontally provided with a through hole at the position of the replacement rod 153. When the second insertion rod 141 is inserted into the interior of the replacement insertion hole 151, the replacement rod 153 can be inserted into the through hole of the second insertion rod 141 to fix the second insertion rod 141, thereby connecting the second column 14 and the replacement column 15.

[0033] A replacement rod 154 is fixedly connected to the bottom end of the replacement column 15. A first insertion hole 131 is vertically opened on the top wall of the first column 13 relative to the position of the replacement rod 154, and a first horizontal hole 132 is horizontally opened on the side wall of the first insertion hole 131. A first rod 133 is horizontally inserted inside the first horizontal hole 132. A through hole is horizontally opened on the replacement rod 154 relative to the position of the first rod 133. When the first rod 133 is inserted into the first insertion hole 131, the first rod 133 can be inserted into the through hole of the replacement rod 154 to fix the replacement rod 154, thereby connecting the replacement column 15 and the first column 13.

[0034] Reference Figure 1 , Figure 2 C-shaped grooves 16 are provided on the side walls of the first column 13, the replacement column 15, and the second column 14. The interior of the first column 13, the replacement column 15, and the second column 14 is a hollow structure, and the interior of the first column 13, the replacement column 15, and the second column 14 is connected to the outside through the C-shaped grooves 16.

[0035] The lifting assembly 3 includes a drive shaft 31 located inside the column 1. A base plate 32 is horizontally arranged at the bottom end of the drive shaft 31. The base plate 32 has a circular structure and is coaxially arranged with the drive shaft 31. A first rotating motor is arranged below the base plate 32. The motor shaft of the first rotating motor is coaxially arranged with the drive shaft 31 and relatively fixedly connected. A second rotating motor is also arranged below the base plate 32. The motor shaft of the second rotating motor is coaxially arranged with the base plate 32 and relatively fixedly connected.

[0036] The drive shaft 31 includes a first drive section 311 located inside the first column 13, a replacement drive section 312 located inside the replacement column 15, and a second drive section 313 located inside the second column 14. The first drive section 311 and the replacement drive section 312 are coaxially arranged and threadedly connected to each other, and the second drive section 313 and the replacement drive section 312 are coaxially arranged and threadedly connected to each other.

[0037] A slide 33 is provided on the outer wall of the drive shaft 31. The slide 33 includes an ascending slide and a descending slide arranged parallel to each other at their bottom ends. The ascending slide 33 and the descending slide 33 are connected to each other at the top of the slide 33. The slide 33 is arranged in a spiral shape along the outer wall of the drive shaft 31.

[0038] Hanger rings 21 are fixedly connected to both ends of the hanger 2. The hanger rings 21 are annular structures and are sleeved on the outside of the drive shaft 31. A slider is fixedly connected to the inner side wall of the hanger ring 21 at a position relative to the slide rail 33. The slider is located inside the slide rail 33 and is slidably connected to it. When the drive shaft 31 is rotated, the slide rail 33 pushes the slider to move inside the slide rail 33, thereby driving the hanger 2 to move along the height direction of the drive shaft 31.

[0039] Reference Figure 2 , Figure 4 A retaining plate 23 is fixedly connected to the top of the side wall of the hanger ring 21. Multiple retaining plates 23 are evenly spaced along the circumference of the hanger ring 21, and the retaining plates 23 have an "L" shape. A slot 17 is provided at the top of the inner side wall of the second column 14 relative to the retaining plate 23. An adjusting plate 18 is vertically arranged inside the slot 17. The two sides and the top of the adjusting plate 18 are respectively spaced from the side wall of the slot 17. The adjusting plate 18 divides the inside of the slot 17 into an entry part 171 and an exit part 173 located on both sides of the adjusting plate 18, and a locking part 172 located at the top of the adjusting plate 18. The entry part 171 and the locking part 172 are relatively connected, and the exit part 173 and the locking part 172 are relatively connected.

[0040] The top of the adjusting plate 18 has a limiting groove 181. When the locking plate 23 enters the locking part 172 from the position of the entry part 171, the locking plate 23 is limited by the limiting groove 181. After being limited, the locking plate 23 is moved upward so that it re-enters the interior of the locking part 172 and then enters the interior of the exit part 173 through the guide of the locking part 172.

[0041] The bottom end of the adjusting plate 18 is a deformable elastic structure. In the initial state, the bottom end of the adjusting plate 18 contacts the side wall of the limiting groove 181 near the exit portion 173, thereby opening one side of the entry portion 171. The locking plate 23 can then enter the interior of the locking portion 172 through the entry portion 171. When the locking plate 23 moves downward from the exit portion 173, it pushes the bottom end of the adjusting plate 18 toward the side near the entry portion 171, thereby opening the bottom end of the exit portion 173. As a result, the locking plate 23 can disengage from the interior of the exit portion 173. After disengagement, the locking plate 23, under the action of elastic deformation, abuts against the side wall of the limiting groove 181 near the exit portion 173.

[0042] Reference Figure 2 , Figure 5 The locking assembly 4 includes a first locking plate 41 and a second locking plate 42 located opposite each other on the base plate 32. The first locking plate 41 and the second locking plate 42 have an arc-shaped structure, and the center of the arc is the same as the axis of the transmission shaft 31. The first locking plate 41 and the second locking plate 42 are sleeved on the outside of the transmission shaft 31.

[0043] A spring 43 is provided at one end of the first locking plate 41 and the second locking plate 42. One end of the spring 43 is fixedly connected to the first locking plate 41, and the other end of the spring 43 is fixedly connected to the second locking plate 42. The end of the first locking plate 41 near the spring 43 is rotatably connected to the base plate 32, and the end of the second locking plate 42 near the spring 43 is rotatably connected to the base plate 32.

[0044] A drive groove 321 is provided on the base plate 32 at the end of the first locking plate 41 away from the spring 43. The drive groove 321 is a strip-shaped groove, and the drive groove 321 is inclined along the circumference of the base plate 32 from the side close to the center of the base plate 32 toward the side away from the center of the base plate 32.

[0045] A drive column 44 is vertically arranged inside the drive groove 321. The drive column 44 is slidably connected to the base plate 32. A first drive rod 441 is fixedly connected to the drive column 44. The end of the first drive rod 441 opposite to the drive column 44 is rotatably connected to the first locking plate 41. A second drive rod 442 is also fixedly connected to the drive column 44. The end of the second drive rod 442 opposite to the drive column 44 is rotatably connected to the second locking plate.

[0046] The second rotating motor drives the base plate 32 to rotate, which in turn drives the internal drive column 44 to move along the direction of the drive groove 321. When the drive column 44 is located at the end of the drive groove 321 near the center of the base plate 32, the drive column 44 drives the first drive rod 441 and the second drive rod 442 to be located at the end near the center of the base plate 32, causing the first locking plate 41 and the second locking plate to open, allowing the transmission shaft 31 to rotate freely. When the drive column 44 is located at the end of the drive groove 321 away from the center of the base plate 32, the drive column 44 drives the first drive rod 441 and the second drive rod 442 to be located at the end away from the center of the base plate 32, causing the first locking plate and the second locking plate to hold the transmission shaft 31 tightly, thereby restricting the rotation of the transmission shaft 31.

[0047] The lifting frame 2 includes a horizontally arranged first lifting section 24 and a second lifting section 25, which are rotatably connected and connected by a pin to allow them to rotate relative to each other. A lifting ring 26 is fixedly connected to the bottom end of the first lifting section 24, which is used to lift objects from the outside.
