Description

Technical Field

[0001] This utility model relates to the field of shipbuilding, and in particular to a hydraulic support rod with easily adjustable height. Background Technology

[0002] Sectional construction is a core component of modern shipbuilding, involving dividing the hull structure into several spatial or planar units (sections). These sections are prefabricated, assembled, and welded in workshops or open platforms before being transported to slipways or dry docks for final assembly. This construction method has transformed the traditional bulk assembly approach, enabling parallel, continuous operations that significantly shorten slipway cycles, improve production efficiency, and increase site utilization. Sectional construction typically involves processes such as steel pretreatment, marking, cutting, edge processing, component welding, section assembly and welding, heat treatment, and precision measurement, demanding high standards for dimensional accuracy, welding deformation control, and surface coating quality. Furthermore, the process requires extensive support equipment (such as adjustable supports, jigs, and steel blocks) to ensure the stability and safety of the sections during welding, storage, and transportation. Through sectional construction, shipyards can achieve specialized division of labor and integrated hull, outfitting, and painting operations, laying the foundation for rapid assembly and high-quality delivery.

[0003] During the construction of ship sections and the assembly of the slipway, a large number of supporting fixtures are required to ensure the stable and safe positioning of the sections. Traditional methods often use channel steel and I-beams welded on-site to form fixed supports, or simple steel blocks with pads. However, traditional channel steel supports are mostly one-time welded structures, which require gas cutting to dismantle during dismantling, cannot be reused, and result in significant material waste. The height of fixed supports cannot be adjusted, and when the level of the section deviates, pads of different thicknesses must be cut on-site for filling, making the adjustment process cumbersome and difficult to meet the high-precision control requirements of modern shipbuilding for section level. Traditional supports lack reliable mechanical locking mechanisms, relying solely on hydraulic pressure or temporary pads for load-bearing. Once the hydraulic system depressurizes or the pads slip, it can easily lead to major safety accidents such as section falls or capsizing. Utility Model Content

[0042] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0043] Figures 1 to 9 The diagram shown is a structural schematic of an embodiment of the height-adjustable hydraulic support rod of this utility model.

[0044] A height-adjustable hydraulic support rod includes a base frame 1, which is connected to the bottom end of the column sleeve 2. Hydraulic jack 3 is installed at the bottom of the inner cavity of the column sleeve 2; The telescopic column 4 is connected to the top of the hydraulic jack 3 via an anti-rotation guide component 8. Locking component 5 is detachably connected to column sleeve 2 and telescopic column 4 respectively. Locking component 5 is used to lock the relative position of column sleeve 2 and telescopic column 4. Top platform 6, the bottom of top platform 6 is connected to the top of telescopic column 4; The support head 7 is connected to the support component 10 at its bottom. The support component 10 is detachably connected to the top of the top platform 6 via the detachable component 11.

[0045] In this technical solution, the main structure of the support rod can be reused an unlimited number of times across projects and sections, the pad loss rate is extremely low, reducing costs and achieving reuse.

[0046] The system uses hydraulic jack 3 for coarse adjustment and locking assembly 5 for fine adjustment. It has a wide height adjustment range and can be adjusted in multiple granularities to adapt to different line types and different height segmentation requirements.

[0047] Meanwhile, different models of support heads can be replaced by support components 10 and disassembly components 11, thereby meeting the support requirements of planar sections and curved side sections.

[0048] The locking assembly 5 includes a locking hole 51 and an adapter hole 52. The column sleeve 2 has multiple locking holes 51 distributed from top to bottom, and the telescopic column 4 has an adapter hole 52. The column sleeve 2 and the telescopic column 4 are detachably connected to the threaded pin shaft 53 through the locking hole 51 and the adapter hole 52, respectively. One end of the threaded pin shaft 53 is threaded with a safety nut 54.

[0049] The distance between two adjacent locking holes 51 is preferably 50mm.

[0050] In this technical solution, a double-safety locking mechanism is achieved through the mechanical locking of the threaded pin shaft 53 and the locking of the safety nut 54. This allows the system to independently bear loads when the hydraulic jack 3 fails, preventing it from falling in sections.

[0051] In use, the hydraulic jack 3 adjusts the height of the telescopic column 4. After adjustment, the threaded pin shaft 53 is installed into the corresponding locking hole 51 and adapter hole 52. Then, the safety nut 54 is installed. The threaded pin shaft 53 and the safety nut 54 are used to mechanically lock the relative position of the column sleeve 2 and the telescopic column 4, thus fixing the height of the main body of the support rod.

[0052] The anti-rotation guide assembly 8 includes a lifting plate 81, the bottom of which is connected to the piston top of the hydraulic jack 3, and the top of which is connected to the bottom of the telescopic column 4. The inner wall of the column sleeve 2 is connected with multiple anti-rotation strips 82 arranged in a ring array. The side of the lifting plate 81 is provided with multiple guide grooves arranged in a ring array. The anti-rotation strips 82 are slidably connected to the lifting plate 81 through the guide grooves.

[0053] In this technical solution, the angle of the lifting plate 81 is limited by the anti-rotation strip 82 to prevent the telescopic column 4 from rotating when it moves.

[0054] In use, the hydraulic jack 3 is used to drive the lifting plate 81 to move along the anti-rotation bar 82, thereby driving the telescopic column 4 to move in the same direction and adjusting the height of the telescopic column 4.

[0055] The support assembly 10 includes a mounting platform 101, with a support bar 102 connected to the bottom of the mounting platform 101, and the bottom end of the support bar 102 connected to the top of the disassembly plate 103; A support head 7 is provided above the mounting platform 101. Multiple sliding columns 104 are connected to the bottom of the support head 7. The surface of the sliding column 104 is slidably connected to the mounting platform 101. An anti-detachment plate 105 is connected to the bottom of the sliding column 104. A spring 106 is connected between the top of the anti-detachment plate 105 and the bottom of the mounting platform 101. The spring 106 is sleeved on the surface of the sliding column 104.

[0056] In this technical solution, the support component 10 facilitates the installation and removal of the support head 7 by the assembly and disassembly component 11.

[0057] A pad 9 is provided between the support head 7 and the mounting platform 101.

[0058] In this technical solution, the height is finely adjusted by increasing or decreasing the number of pads 9.

[0059] The pad 9 includes one or more combinations of 100T, 60T, and 20T.

[0060] The assembly / disassembly component 11 includes a fixing column 111, the bottom end of which is connected to the top of the top platform 6, and the top end of which is connected to the bottom of the fixing platform 112. A disassembly plate 103 is placed on the top of the fixed platform 112. Multiple disassembly racks 113 are connected to the top of the disassembly plate 103. A locking tooth plate 114 is provided above the disassembly racks 113. When the disassembly racks 113 and the locking tooth plate 114 are in contact, they engage.

[0061] In this technical solution, the support component 10 and the support head 7 are installed and disassembled by the disassembly and assembly component 11.

[0062] Guide sliders 115 are connected to both sides of the locking tooth plate 114. A sliding groove is provided on the inner side of the fixed platform 112. The guide sliders 115 slide in the sliding groove and are slidably connected to the fixed platform 112 through the sliding groove.

[0063] The bottom of the locking tooth plate 114 is connected to a locking plate 116, which is detachably connected to the side of the fixing post 111 by a disassembly bolt 117.

[0064] In this technical solution, the position of the locking tooth plate 114 is locked by the locking plate 116 and the disassembly bolt 117.

[0065] The disassembly bolt 117 is threaded to the side of the fixing post 111.

[0066] In use, the disassembly plate 103 is placed on top of the fixed platform 112, and then the locking tooth plate 114 is slid to drive the guide slider 115 to move in the same direction. The locking tooth plate 114 approaches and fits tightly against the disassembly rack 113, so that the disassembly rack 113 and the locking tooth plate 114 are engaged. At this time, the locking plate 116 is close to the fixed post 111. Then the disassembly bolt 117 is installed so that the disassembly bolt 117 fixes the locking plate 116 to the side of the fixed post 111, thereby locking the position of the locking tooth plate 114. At this time, the locking toothed plate 114 and the disassembly and assembly toothed rack 113 can limit the position of the disassembly and assembly plate 103 from the top and bottom, left and right, and front and back, increasing the stability of the support component 10 and the support head 7. At the same time, the operation is convenient, making the disassembly, assembly and replacement of the support head 7 and other structures more convenient.

[0067] The bottom of the base frame 1 is connected to two symmetrically distributed fixed bases 12. Each fixed base 12 has a telescopic base 13 on both sides. The two telescopic bases 13 are connected to the fixed bases 12 through telescopic components 14. Multiple side support assemblies 15 are connected between the top of the two telescopic bases 13 and the two sides of the top platform 6.

[0068] In this technical solution, the position of the telescopic base 13 is adjusted by the telescopic component 14, thereby increasing the support area between the support rod and the ground and increasing the stability of the support rod.

[0069] The stability of the support rod is further increased by the side support assembly 15.

[0070] Both the fixed base 12 and the telescopic base 13 have multiple anchor holes.

[0071] In use, the fixed base 12 and the telescopic base 13 are fixed to the ground by ground anchor rods and anchor holes.

[0072] The telescopic assembly 14 includes telescopic slide columns 141. Multiple telescopic slide columns 141 are connected to the side of the telescopic base 13 near the fixed base 12. A follower plate 142 is connected to the end of the telescopic slide column 141 away from the telescopic base 13. The surface of the follower plate 142 is slidably connected to the side of the telescopic base 13. A reinforcing plate 143 is connected to one side of the follower plate 142. The reinforcing plate 143 is slidably connected to the inner wall of the telescopic base 13. The telescopic base 13 is connected to a fixed sleeve 144 on its side. The surface of the telescopic slide column 141 is slidably connected to the fixed sleeve 144. Both the telescopic slide column 141 and the fixed sleeve 144 are threadedly connected to the fixing bolt 145.

[0073] In this technical solution, the position of the telescopic base 13 is locked by the telescopic component 14.

[0074] The fixed sleeve 144 has a threaded hole, and the telescopic slide 141 has multiple threaded grooves. The telescopic slide 141 and the fixed sleeve 144 are respectively threaded to the fixed bolt 145 through the threaded grooves and threaded holes.

[0075] The fixing bolt 145 can lock the relative position between the telescopic slide 141 and the fixing sleeve 144, thereby locking the position of the telescopic base 13.

[0076] The side support assembly 15 includes two telescopic support bars 152, which are slidably connected to the inner wall of the central sleeve 151. Both the central sleeve 151 and the telescopic support bars 152 are detachably connected to the positioning bolt group 153. Two central housings 151 are each connected to a rotating block 154 at the end away from the telescopic support bar 152. The rotating block 154 is rotatably connected to the fixed frame 155. The fixed frames 155 at both ends are respectively connected to the top of the telescopic base 13 and the side of the top platform 6.

[0077] In this technical solution, the top platform 6 is provided with auxiliary support through the side support component 15.

[0078] The telescopic support bar 152 has a first locking hole at the end away from the rotating block 154, and the central sleeve 151 has multiple second locking holes. The positioning bolt group 153 is detachably connected to the telescopic support bar 152 and the central sleeve 151 through the first locking hole and the second locking hole, respectively.

[0079] In use, the telescopic support bar 152 can slide along the central sleeve 151, and the rotating block 154 can rotate around the fixed frame 155, so that the central sleeve 151 and the telescopic support bar 152 can be adaptively adjusted according to the height of the top platform 6 and the position of the telescopic base 13. When under stress, the positioning bolt group 153 is used to lock the position of the central sleeve 151 and the telescopic support 152, thereby providing auxiliary support for the top platform 6 and improving the stability of the top platform 6.
