Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to an integral hydraulic lifting device for steel connecting corridors. Background Technology

[0002] The integrated hydraulic lifting device for steel connecting corridors is used to safely and efficiently lift steel structure connecting corridors to their designated positions. The design and application of this device have greatly improved the efficiency and quality of building construction, making a significant contribution to the development of the modern construction industry.

[0003] The existing integrated hydraulic lifting device for steel corridors mainly includes a support frame, a hydraulic lifter, and steel strands. The hydraulic lifter is installed on the support frame, which is usually installed on the top of the two buildings at both ends of the steel corridor. The steel strands pass through the hydraulic lifter and are connected to the steel corridor. Then, the hydraulic lifter pulls the steel strands upward, thereby lifting the steel corridor to the predetermined position. Finally, the steel corridor is fixed between the two buildings.

[0004] However, after the steel strands are fixed to the steel corridor, to ensure safe construction, the hydraulic lift needs to first raise the steel corridor 10-20 cm, and then let it stand for 12-24 hours. During the standing period, a comprehensive inspection of the hydraulic lifting device is required. Only when it is confirmed that the hydraulic lifting device is functioning normally in all aspects can the steel corridor be raised to the predetermined position. This step can avoid the safety problem of the steel corridor suddenly falling during the lifting process due to structural failures of the support, hydraulic lift, or steel strands. Therefore, the existing integrated hydraulic lifting device for steel corridors has the following defects when used when the predetermined position of the steel corridor is low: For example, when constructing a steel corridor between two adjacent steel structure workshops, since steel structure workshops are usually only two or three stories high, their height is relatively low compared to high-rise residential and commercial buildings. Therefore, the planned height of the steel corridor is relatively low. However, when lifting the steel corridor, it still needs to be left to stand for a day, which affects the overall construction efficiency. Utility Model Content

[0005] The purpose of this utility model is to at least solve one of the technical defects described in the background art.

[0006] Therefore, one objective of this utility model is to propose an integrated hydraulic lifting device for steel connecting corridors, which aims to solve the problem of low construction efficiency when using existing integrated hydraulic lifting devices for steel connecting corridors at predetermined locations.

[0007] To achieve the above objectives, one embodiment of this utility model provides an integral hydraulic lifting device for a steel corridor, comprising four bases, multiple steel columns, and supports. The tops of the four bases are all fixedly connected to hydraulic cylinders and support columns. The four corners of the bottom of each support are all fixedly connected to support legs one and support legs two. Multiple steel columns are fixedly installed between the hydraulic cylinders and support legs one, and multiple steel columns are fixedly installed between the support columns and support legs two.

[0008] The beneficial effects are as follows: After the hydraulic cylinders and support legs on the base are assembled with the steel columns and supports, they can support the steel corridor. Then, by assembling the steel columns section by section, the steel corridor can be lifted. Because the base is placed directly on the ground to provide support, there is no need to worry about the supports falling. Therefore, after the steel corridor is built on the supports, it does not need to be left to stand and can be lifted directly. This saves time and improves construction efficiency when lifting steel corridors between two adjacent buildings such as factories that are only two or three stories high.

[0009] Preferably, in any of the above embodiments, a positioning column is fixedly connected to the piston rod end of the hydraulic cylinder, and positioning columns are fixedly connected to the top ends of the support column and the steel column. Positioning holes are provided at the bottom ends of the steel column, the first support leg, and the second support leg. A chamfer is provided on the outer surface of the top end of the positioning column.

[0010] The beneficial effects are as follows: When dismantling the device, after the flange between the top of the hydraulic cylinder and the support column and the bottom of the steel column is disassembled, the positioning column is inserted into the corresponding positioning hole when dismantling the steel column section by section, so that the top of the hydraulic cylinder and the support column are simply fixed to the bottom of the steel column. Therefore, the flange between the hydraulic cylinder and the support column and the steel column does not need to be connected and fixed, thus saving some time for disassembling and assembling bolts and achieving the purpose of facilitating disassembly.

[0011] Preferably, the top of the support has multiple insertion holes, and a limit post is inserted into each of the multiple insertion holes.

[0012] The beneficial effects are as follows: during the lifting process of the steel corridor, if the four hydraulic cylinders are not completely synchronized, causing the support to tilt slightly, the limiting column can limit the steel corridor, thereby avoiding the problem of the steel corridor sliding, misalignment, or even falling, thus improving safety.

[0013] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] This utility model provides an integrated hydraulic lifting device for steel connecting corridors.

[0024] Example 1: like Figure 1-2As shown, it includes four bases 1, multiple steel columns 2, and supports 3. Flanges are fixedly connected to both ends of the steel columns 2. Hydraulic cylinders 11 and support columns 12 are fixedly connected to the tops of the four bases 1. Flanges are fixedly connected to the piston rod ends of the hydraulic cylinders 11 and to the top of the support columns 12. Support legs 1 31 and 2 32 are fixedly connected to the four corners of the bottom of the supports 3. Flanges are fixedly connected to the bottom ends of support legs 1 31 and 2 32. Multiple steel columns 2 are fixedly installed between the hydraulic cylinders 11 and support legs 1 31, and are connected via flanges. Support columns 2 and support legs 1 31 are also connected via flanges. Multiple steel columns 2 are fixedly installed between support columns 12 and support legs 2 32, and are connected via flanges.

[0025] In this embodiment, four bases 1 are placed on the ground between two adjacent buildings. Then, the supports 3 are lifted above the four bases 1 using a forklift or crane. The four outriggers 31 below the supports 3 are fixedly installed on the top of the hydraulic cylinder 11 using flanges. Then, a steel connecting corridor is built on top of the supports 3. After the steel connecting corridor is built, the lifting operation is carried out according to the following steps: Step 1: Simultaneously extend the four hydraulic cylinders 11 to lift the support 3, so that the distance between the second outrigger 32 and the support column 12 is slightly greater than the length of the steel column 2. Step 2, as follows Figure 1 As shown, four steel columns 2 are placed above four support columns 12 respectively, and then the support 3 is lowered so that the second support leg 32 presses on the steel columns 2. Then the structure is fixed by the flange. Step 3, as follows Figure 2 As shown, the hydraulic cylinder 11 is separated from the outrigger 31, and the piston rod of the lowering hydraulic cylinder 11 is retracted. Then, the steel column 2 is placed between the hydraulic cylinder 11 and the outrigger 31 and fixed by the flange. Step 4: Separate the support column 12 from the steel column 2, extend the hydraulic cylinder 11, lift the support 3 again, and then install the new steel column 2 on top of the support column 12. Step 5: Separate the hydraulic cylinder 11 from the steel column 2 above it, retract the piston rod of the lowering hydraulic cylinder 11, and then install a new steel column 2 above the hydraulic cylinder 11. Step 6: Repeat steps 4 and 5 in sequence until the steel corridor on support 3 is raised to the predetermined height, and then fix the steel corridor between the two adjacent buildings.

[0026] Example 2: like Figure 3-5As shown, based on Embodiment 1, a positioning pin 4 is fixedly connected to the piston rod end of the hydraulic cylinder 11. Positioning pins 4 are also fixedly connected to the top of the support column 12 and the top of the steel column 2. Positioning holes 5 are opened at the bottom ends of the steel column 2, the first support leg 31 and the second support leg 32. The positioning pin 4 is inserted into the positioning hole 5, which can initially fix the connection between the hydraulic cylinder 11, the steel column 2 and the first support leg 31, or initially fix the connection between the support column 12, the steel column 2 and the second support leg 32. After initial fixation, it is convenient to align the holes on the flange, thereby facilitating the insertion and connection of bolts.

[0027] Preferably, the outer surface of the top of the positioning post 4 is chamfered to reduce the diameter of the top of the positioning post 4, thereby facilitating the insertion of the positioning post 4 into the positioning hole 5.

[0028] In this embodiment, when lifting the steel connecting corridor, the operation is carried out according to steps one to six in embodiment one. During the lifting process, due to the setting of positioning column 4 and positioning hole 5, it is convenient to initially position the steel column 2 when installing it. After the initial positioning, it is convenient to align the holes on the flange, thereby facilitating the insertion and connection of bolts. When dismantling the steel connecting corridor after it has been fixed between two adjacent buildings, follow these steps: Step 1: Retract the hydraulic cylinder 11 and lower the support 3 so that the steel column 2 at the top of the support column 12 falls on top of the support column 2. The positioning column 4 at the top of the support column 12 is inserted into the positioning hole 5 at the bottom of the steel column 2, so that a simple connection is made between the support column 12 and the steel column 2. Step 2: Remove the bolts inside the flange at the end of the steel column 2 at the top of the hydraulic cylinder 11, and then retract the hydraulic cylinder 11 again to lower the steel column 2 being disassembled. This will disengage the corresponding positioning column 4 from the corresponding positioning hole 5, allowing the steel column 2 above the hydraulic cylinder 11 to be disassembled. (Since the top of the support 3 no longer has a steel connecting corridor, it is lighter in weight, so the flange between the support column 12 and the steel column 2 at its top can still provide stable support for the support 3 without using bolts for fixing.) Step 3: Remove the bolts on the flange at the top of the steel column 2 above the support leg 12, then extend the hydraulic cylinder 11 to lift the support 3, thereby removing the steel column 2 above the support leg 12. Step 4: Repeat steps 1 to 3 until all steel columns are removed. Finally, use a crane or forklift to remove the support 3 from the top of the hydraulic cylinder 11.

[0029] Example 3: like Figure 6As shown, based on Embodiment 1 or Embodiment 2, the top of the support 3 is provided with multiple insertion holes 33, and limit posts 34 are inserted into the multiple insertion holes 33. After the steel corridor is built on the support 3, the multiple limit posts 34 are inserted into the corresponding insertion holes 33, so that the limit posts 34 are stuck on both sides of the bottom of the steel corridor, thereby limiting the steel corridor. Thus, during the process of lifting the steel corridor, if the four hydraulic cylinders are not completely synchronized, and the support 3 tilts slightly, the limit posts 34 can limit the steel corridor, thereby avoiding the problem of the steel corridor sliding, misaligning, or even falling.
