Description

Technical Field

[0001] This application relates to the field of hydraulic lifting technology, and in particular to a support structure for an operating platform of a hydraulic lifting template system. Background Technology

[0002] Hydraulic slipform construction (or slipform for short) is a continuous forming construction technique for cast-in-place concrete engineering, widely used in the construction of tall structures such as chimneys, ash silos, and silos, as well as the core tubes of high-rise buildings. This technology involves pre-installing the slipform device according to the plan shape of the object being constructed. By continuously binding reinforcing bars and pouring concrete in layers within the formwork, a hydraulic lifting device is used to slide the slipform device off the ground and continuously raise it upwards until the designed height is reached. This construction method has technical advantages such as continuous operation, high degree of mechanization, and fast construction speed, and holds an irreplaceable position in large-scale civil engineering and industrial construction.

[0003] The hydraulic slipform system includes an operating platform, jacks, and support rods (climbing rods). The jacks are installed above the concrete body via the support rods to lift the operating platform mechanism relative to the upper surface of the concrete. The support rods can be made of thick steel bars and welded to the steel reinforcement structure of the concrete body. After the concrete is poured, the support rods also serve as the steel reinforcement structure.

[0004] However, since the jack needs to move the entire steel platform upwards, and the steel platform is quite heavy, the connection strength between the jack and the steel platform needs to be strong to increase the stability of the operating platform and the jack installation. Therefore, there is a need to provide a hydraulic lifting formwork system that can improve the stability of the operating platform installed on the jack. Utility Model Content

[0005] To improve the stability of the operating platform installed on the jack, this application provides a support structure for the operating platform of a hydraulic lifting template system.

[0006] The supporting structure of the hydraulic lifting formwork system operating platform provided in this application adopts the following technical solution:

[0007] A support structure for a hydraulic lifting formwork system operating platform includes a jack, a support rod, and a connecting assembly. The support rod is installed in the concrete body and passes through the middle of the jack. The connecting assembly is used to connect the jack to the operating platform. The connecting assembly includes a support ring plate, a plug rod, a first connector, and a second connector. The support ring plate is sleeved on the outer wall of the jack and connected to the jack. The operating platform has a connection hole through which the jack passes, and the support ring plate abuts against the bottom wall of the operating platform.

[0008] The support ring plate has a first mounting hole, and the operating platform has a second mounting hole for communicating with the first mounting hole. The plug rod passes through the first mounting hole and the second mounting hole. The first connector is fixed to the plug rod, and the second connector is detachably installed on the plug rod. The support ring plate and the operating platform are clamped between the first connector and the second connector.

[0009] By adopting the above technical solution, the support ring plate is sleeved on the outer wall of the jack, which increases the contact area, can disperse the load transmitted by the operating platform, avoid local stress concentration, and thus increase the stability of the connection between the operating platform and the jack; it can also reduce the risk of tilting caused by construction vibration and ensure the relative position stability of the jack and the operating platform in the horizontal plane.

[0010] Moreover, the first connector is fixed to the plug rod, and the second connector is detachably installed on the plug rod. The two form a two-way clamping of the support ring plate and the operating platform, which prevents relative displacement between the jack and the operating platform and further increases the stability of the connection between the jack and the operating platform.

[0011] Optionally, the second connector includes a mounting ring, the inner wall of which is provided with a first threaded portion, and the outer wall of the plug rod is provided with a second threaded portion for engaging with the first threaded portion.

[0012] By adopting the above technical solution, the first threaded part of the mounting ring and the second threaded part of the plug rod are threaded together, which can realize the connection between the mounting ring and the plug rod, thereby clamping the mounting ring and the first connecting piece on opposite sides of the operating platform and the support ring plate, improving the stability of the connection between the jack and the operating platform.

[0013] Optionally, the second connector includes an anti-detachment ring, a plug block, and a plug-in part. The anti-detachment ring is sleeved on the outer wall of the plug rod. The inner wall of the anti-detachment ring is provided with an installation groove, and the plug block is movably installed in the installation groove. The outer wall of the plug rod is provided with a plurality of plug slots for the plug block to be inserted into, and the plug-in part is used to drive the plug block to be inserted into the plug slot.

[0014] By adopting the above technical solution, the plug-in block and the plug-in slot can be plugged together to connect the anti-detachment ring and the plug-in rod, so that the operating platform and the support ring plate are sandwiched between the first connector and the anti-detachment ring. At the same time, the anti-detachment ring is avoided by rotating it multiple times, which improves the installation efficiency of the anti-detachment ring and the plug-in rod.

[0015] Optionally, a clamping plate is provided on one side of the anti-detachment ring. The clamping plate is connected to the anti-detachment ring via a first screw and is used to abut against the support ring plate / operating platform.

[0016] By adopting the above technical solution, after the plug-in block and the plug-in slot are plugged in, there may be a gap between the anti-detachment ring and the operating platform or the support ring plate. With the cooperation of the first screw and the clamping plate, the anti-detachment ring and the first connecting piece can be pressed against the opposite sides of the operating platform and the support ring plate, thereby increasing the stability of the connection between the operating platform and the jack.

[0017] Optionally, the plug portion is configured as a first spring, which is installed in the mounting groove.

[0018] By adopting the above technical solution, the plug-in part is set as the first spring installed in the mounting groove, which can drive the plug-in block to be inserted into the plug-in groove, thereby increasing the stability of the anti-detachment ring installed on the plug-in rod.

[0019] Optionally, the insertion part includes a first airbag, a second spring, and multiple second airbags. A compression chamber is installed inside the anti-detachment ring, and the first airbag is installed inside the compression chamber. Multiple sets of insertion blocks are provided, and the mounting slots are all connected to the compression chambers. The second airbags are installed in the mounting slots and connected to the insertion blocks, and the second airbags are connected to the first airbags. The anti-detachment ring is provided with a second screw for squeezing the first airbag, and the second spring is used to drive the first airbag to return to its inflated state.

[0020] By adopting the above technical solution, multiple sets of plug-in blocks are set up. The second screw squeezes the first airbag, which can squeeze the gas in the first airbag into multiple second airbags, so that multiple plug-in blocks can be inserted into the plug-in slots at the same time, improving the installation efficiency. The connection strength between the anti-detachment ring and the plug-in rod is enhanced. When the connection between the anti-detachment ring and the plug-in rod is canceled, the second bolt is rotated in the opposite direction, and the elastic force of the second spring causes the first airbag to recover its expansion, allowing the gas in the second airbag to return to the first airbag, and all plug-in blocks no longer plug into all plug-in slots.

[0021] Optionally, the support ring plate is integrally formed with the jack.

[0022] By adopting the above technical solution, the connection strength between the support ring plate and the jack can be increased, thereby increasing the stability of the operating platform after it is connected to the jack.

[0023] Optionally, the first mounting hole is configured as an oblong hole.

[0024] By adopting the above technical solution, the first mounting hole is set as an oblong hole, which can provide a certain adjustment space during installation, making it easy for the plug rod to pass through smoothly, improving the convenience and adaptability of installation, and enhancing the connection strength between the jack and the operating platform.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The support ring plate is fitted onto the outer wall of the jack, which increases the contact area, can disperse the load transmitted by the operating platform, avoid local stress concentration, and thus increase the stability of the connection between the operating platform and the jack; it can also reduce the risk of tilting caused by construction vibration and ensure the relative position stability of the jack and the operating platform in the horizontal plane.

[0027] 2. The plug-in block and the plug-in slot can connect the anti-detachment ring and the plug-in rod, so that the operating platform and the support ring plate are clamped between the first connector and the anti-detachment ring, while avoiding multiple rotations of the anti-detachment ring and improving the installation efficiency of the anti-detachment ring and the plug-in rod.

[0034] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0035] Example 1:

[0036] This application provides a support structure for a hydraulic lifting template operation platform 8.

[0037] Reference Figure 1A support structure for a hydraulic lifting template operating platform 8 includes a jack 1, a support rod 2, and a connecting component 3. The support rod 2 is installed on a concrete body 9 and passes through the middle of the jack 1. The connecting component 3 is used to connect the jack 1 to the operating platform 8. This combination allows the operating platform 8 to be stably lifted on the support rod by the jack 1.

[0038] Specifically, the connecting component 3 includes a support ring plate 4, a plug-in rod 5, a first connecting piece 6, and a second connecting piece 7. The support ring plate 4 is sleeved on the outer wall of the jack 1 and connected to the jack 1. It can be made of metal, such as steel, which has high strength and stability. In some alternative solutions, high-strength alloy materials can also be used. The connection between the support ring plate 4 and the jack 1 can be integrally formed, which makes the connection more secure and reduces the possibility of loosening; in this embodiment, the jack 1 and the support ring plate 4 are integrally formed.

[0039] The operating platform 8 has a connection hole 81 through which the jack 1 passes, and the support ring plate 4 abuts against the bottom wall of the operating platform 8. The operating platform 8 is generally a frame structure welded from metal plates, possessing a certain load-bearing capacity. The location of the connection hole 81 needs to be precisely determined to ensure that the jack 1 can accurately pass through and cooperate with the operating platform 8.

[0040] The support ring plate 4 has a first mounting hole 41, and the operating platform 8 also has a second mounting hole 82 for communicating with the first mounting hole 41. The plug rod 5 passes through the first mounting hole 41 and the second mounting hole 82. Here, the first mounting hole 41 is set as an oblong hole. The oblong hole design facilitates the installation and adjustment of the plug rod 5. In actual operation, even if the mounting hole positions of the support ring plate 4 and the operating platform 8 are slightly deviated, the plug rod 5 can still be inserted smoothly.

[0041] The connector 5 passes through the first mounting hole 41 and the second mounting hole 82. It is typically a cylindrical metal rod, made of carbon steel, which offers good strength and toughness. Alternatively, a stainless steel rod can be used. The length of the connector 5 is determined based on the thickness of the support ring plate 4 and the operating platform 8, ensuring smooth passage and allowing sufficient length for installing the first connector 6 and the second connector 7.

[0042] The first connector 6 is fixed to the plug rod 5. The first connector 6 can be a circular steel plate welded to one end of the plug rod 5. Its diameter should be larger than the diameter of the first mounting hole 41 and the second mounting hole 82 to ensure that it can play a fixing role.

[0043] The second connector 7 is detachably installed on the plug rod 5. In this embodiment, the second connector 7 includes a mounting ring 71. The inner wall of the mounting ring 71 is provided with a first threaded portion, and the outer wall of the plug rod 5 is provided with a second threaded portion 51 for cooperating with the first threaded portion.

[0044] The mounting ring 71 can be made of metal and connected to the plug rod 5 via a threaded connection. This connection method is simple, convenient, and easy to disassemble and install. When the mounting ring 71 is tightened, the support ring plate 4 and the operating platform 8 are tightly clamped between the first connector 6 and the mounting ring 71, improving the stability of the connection.

[0045] The implementation principle of this embodiment is as follows: By setting up the connecting component 3, and utilizing the cooperation of the support ring plate 4, the plug rod 5, the first connecting piece 6, and the second connecting piece 7, the jack 1 and the operating platform 8 are firmly connected together. The support ring plate 4 abuts against the bottom wall of the operating platform 8. The plug rod 5 passes through the first mounting hole 41 and the second mounting hole 82, and the first connecting piece 6 and the second connecting piece 7 clamp and fix the support ring plate 4 and the operating platform 8, thereby improving the stability of the operating platform 8 installed on the jack 1.

[0046] Example 2:

[0047] Reference Figure 2 and Figure 3 The difference between Embodiment 2 and Embodiment 1 lies in that the second connecting member 7 includes an anti-detachment ring 72, a plug-in block 73, and a plug-in portion 74. The anti-detachment ring 72 is sleeved on the outer wall of the plug-in rod 5; it is typically a ring-shaped component made of metal or plastic. The inner wall of the anti-detachment ring 72 has a mounting groove 721 for accommodating the plug-in block 73. The plug-in block 73 is movably installed within the mounting groove 721; it is generally a square or round block made of metal, possessing a certain degree of hardness and wear resistance. The outer wall of the plug-in rod 5 has multiple plug-in slots 52 for the plug-in block 73 to be inserted into, and the plug-in portion 74 is used to drive the plug-in block 73 into the plug-in slots 52.

[0048] Reference Figure 3 The insertion part 74 can be configured as a first spring 741, which is installed in the mounting groove 721. When the anti-detachment ring 72 is fitted onto the insertion rod 5, the first spring 741 will push the insertion block 73 into the insertion groove 52, thereby fixing the anti-detachment ring 72 to the insertion rod 5. This method has a simple structure and low cost.

[0049] In addition, a retaining plate 76 is provided on one side of the anti-detachment ring 72. The retaining plate 76 is connected to the anti-detachment ring 72 via a first screw 77. The retaining plate 76 is annular, and one end of the first screw 77 is rotatably connected to the retaining plate 76. By driving the first screw 77, the retaining plate 76 can be brought into contact with the support ring plate 4 / operating platform 8. The retaining plate 76 can be a metal plate. By adjusting the first screw 77, the retaining plate 76 can be pressed tightly against the support ring plate 4 or operating platform 8, further enhancing the stability of the connection.

[0050] Example 3:

[0051] Reference Figure 4 and Figure 5 The difference between Embodiment 3 and Embodiment 2 is that the insertion part 74 may include a first airbag 742, a second spring 744, and multiple second airbags 743. A compression chamber 723 is installed inside the anti-detachment ring 72, and the first airbag 742 is installed inside the compression chamber 723. Multiple sets of insertion blocks 73 are provided, and the mounting grooves 721 are all connected to the compression chambers 723. The second airbags 743 are installed in the mounting grooves 721 and connected to the insertion blocks 73, and the second airbags 743 are connected to the first airbags 742.

[0052] The anti-detachment ring 72 is equipped with a second screw 745 for compressing the first airbag 742, and a second spring 744 for driving the first airbag 742 back to its inflated state. When the second screw 745 is rotated to compress the first airbag 742, the gas inside the first airbag 742 enters the second airbag 743, causing the second airbag 743 to inflate, thereby pushing the insertion block 73 into the insertion slot 52. This method allows for adjustment of the insertion force of the insertion block 73 by controlling the rotation of the second screw 745, making it more flexible and reliable.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
