Description

Technical Field

[0001] This invention belongs to the field of steel structure construction technology, specifically relating to a cup-shaped hydraulic straightening device for steel columns. Background Technology

[0002] As the longitudinal main load-bearing components of a steel structure, the installation quality and precision of steel columns directly affect the safety of the entire steel structure building. Currently, in steel structure construction, steel columns are typically assembled using cranes or tower cranes. However, the upper steel columns are unstable during hoisting, and precise alignment between the upper and lower steel columns is difficult.

[0003] For example, the invention disclosed in CN209353754U discloses a straightening device for steel column docking, used to adjust the position of an upper steel column docked at the top of a lower steel column. The straightening device includes a support located at the docking position of the lower and upper steel columns, the support having a lower fixing surface detachably attached to and fixed to the side of the lower steel column; and a vertical jack detachably fixed to the support and corresponding to the upper steel column. The vertical jack includes a vertical cylinder fixed to the support and a vertical push rod telescopically connected to the vertical cylinder, the vertical push rod having an upper fixing surface detachably attached to and fixed to the side of the upper steel column. The upper fixing surface and the lower fixing surface are located in the same vertical plane, so that the corresponding sides of the upper and lower steel columns are located in the same vertical plane. By telescopically extending the vertical push rod, the upper steel column is moved vertically to achieve straightening.

[0004] In the process of developing this application, the following problems were discovered with this technology: The traditional method for straightening steel columns in a steel structure cup-shaped foundation involves using lifting equipment to hoist the steel column into the cup-shaped foundation and temporarily fix it. Then, a steel plate needs to be welded to the steel column at a position 350mm above the cup-shaped foundation. Jacks are then used to straighten the steel column. This method, due to the welding of steel plates to the steel column, causes thermal damage to the original structure of the steel column. Furthermore, the steel column needs to be welded on all four sides, wasting labor and auxiliary materials. The straightening process requires the assistance of certain equipment, wasting mechanical costs, and there are also potential safety hazards in its use. This phenomenon has become a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide a hydraulic cup-mouth straightening device for steel columns, in order to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a hydraulic straightening device for a steel column, comprising a hydraulic jack assembly, a steel column, and a cup. The steel column is located below the bottom of the cup. The hydraulic jack assembly includes a hydraulic jack and a hydraulic fixing pipe, with the hydraulic fixing pipe passing through the hydraulic jack and fixedly connected. The hydraulic jacks firmly fix the steel column and the cup, and the hydraulic jacks are distributed on the four sides of the steel column. The hydraulic jack assembly is provided with a sliding component, which passes through the hydraulic jack and is fixedly connected to the hydraulic jack. The sliding component connects the hydraulic jack assemblies distributed on each side of the steel column in series, and the sliding component is fixed at the top of the hydraulic jack and contacts the inside of the cup.

[0007] The present invention further describes that the sliding assembly includes a sliding plate, which is fixedly connected to a hydraulic jack. The surface of the sliding plate is provided with balls, which are movably connected to the sliding plate. The balls are arranged in an array on the sliding plate and are in contact with the inner side of the cup opening. The sliding plate is provided with a transverse lead screw and a longitudinal lead screw, which penetrate the interior of the sliding plate and are movably connected to the sliding plate. The top ends of the transverse and longitudinal lead screws are provided with a transverse motor and a longitudinal motor, which are electrically connected to the transverse and longitudinal lead screws.

[0008] The present invention further illustrates that the hydraulic fixing pipe is provided with a fixing module, and the hydraulic fixing pipe passes through the fixing module, and the fixing module is welded to the hydraulic fixing pipe. The fixing module includes a telescopic bolt, a front fixing module and a rear fixing module, and the rear fixing module is welded to the fixing module, and the front fixing module is fixedly connected to the telescopic bolt, and the telescopic bolt is threadedly connected to the fixing module.

[0009] The present invention further illustrates that the top of the hydraulic fixing pipe is provided with a hydraulic oil pipe, and the hydraulic oil pipe is engaged with the hydraulic fixing pipe; the end of the hydraulic oil pipe is provided with a hydraulic output pipe, and the hydraulic output pipe is engaged with the hydraulic oil pipe.

[0010] The present invention further illustrates that the hydraulic output pipe is located at the top of the mobile hydraulic operating platform and is fixedly connected to the mobile hydraulic operating platform. The top of the mobile hydraulic operating platform is equipped with a hydraulic pump, and the hydraulic pump is fixedly connected to the mobile hydraulic operating platform.

[0011] The present invention further illustrates that each side of the steel column is fixed by two hydraulic jacks, and each hydraulic jack has two hydraulic jacks.

[0012] The present invention further illustrates that the top end of the hydraulic fixing pipe of each hydraulic assembly is connected to a hydraulic oil pipe, and the hydraulic oil pipes are interconnected.

[0013] Compared with the prior art, the beneficial effects achieved by the present invention are: the present invention,

[0014] (1) By setting up multiple independent hydraulic jacks, pressure is applied to the steel column from different directions to complete the correction and fixation of the steel column. This avoids the problem of welding steel plates on the steel column in traditional steel column correction, which damages the original structure of the steel column through thermal effect, and the need for welding on all four sides of the steel column. In addition, multiple independent hydraulic jacks facilitate installation and disassembly, reduce waste, and improve correction efficiency;

[0015] (2) By setting up sliding components, the steel column can be adjusted more precisely during installation and fixing, avoiding the single and limited use and improving the flexibility of use;

[0016] (3) By setting up a fixed module, the steel column is more secure when fixed at the cup opening, which improves the safety during operation. Attached Figure Description

[0025] The following detailed, non-limiting description of the technical solution of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0026] Please see Figure 1-6 The present invention provides a technical solution: a cup-mouth hydraulic straightening device for a steel column, comprising a hydraulic jack assembly 3, a steel column 5, and a cup mouth 7. The steel column 5 is located below the bottom of the cup mouth 7. The hydraulic jack assembly 3 comprises a hydraulic jack 301 and a hydraulic fixing pipe 302, and the hydraulic fixing pipe 302 passes through the hydraulic jack 301 and is fixedly connected. The hydraulic jack 301 fixes the steel column 5 and the cup mouth 7 firmly. The hydraulic jack 301 is distributed on the four sides of the steel column 5. The hydraulic jack assembly 3 is provided with a sliding component 9, and the sliding component 9 passes through the hydraulic jack 301 and is fixedly connected to the hydraulic jack 301. The sliding component 9 connects the hydraulic jack assemblies 3 distributed on each side of the steel column 5 in series, and the sliding component 9 is fixed at the top of the hydraulic jack 301 and contacts the inside of the cup mouth 7.

[0027] By using the hydraulic jacks 3 set around the steel column 5, the steel column 5 is firmly pressed against the cup opening 7. The sliding component 9, which is fixed to the hydraulic jacks 301, can make more precise adjustments to the fixed steel column 5, allowing the steel column 5 to be adjusted in different directions within the cup opening 7, thereby achieving the purpose of correcting the steel column 5.

[0028] The sliding assembly 9 includes a sliding plate 901, which is fixedly connected to the hydraulic jack 301. The surface of the sliding plate 901 is provided with balls 902, which are movably connected to the sliding plate 901 and arranged in an array on the sliding plate 901. The balls 902 are in contact with the inner side of the cup mouth 7. The sliding plate 901 is provided with a transverse lead screw 904 and a longitudinal lead screw 906, which pass through the interior of the sliding plate 901 and are threaded through the sliding plate 901. The top ends of the transverse lead screw 904 and the longitudinal lead screw 906 are provided with a transverse motor 903 and a longitudinal motor 905, which are electrically connected to the transverse lead screw 904 and the longitudinal lead screw 906.

[0029] Because the sliding plate 901 is located at the top of the hydraulic jack 301, and the ball bearings 902 on the sliding plate 901 contact the inside of the cup opening 7, the ball bearings 902 arrayed on the sliding plate 901 can move horizontally and vertically under the drive of the motor and the lead screw, which improves the accuracy of the steel column 5 correction, avoids the single and limited use, and improves the flexibility.

[0030] A fixing module 8 is provided on the hydraulic fixing pipe 302, and the hydraulic fixing pipe 302 passes through the fixing module 8. The fixing module 8 is welded to the hydraulic fixing pipe 302. The fixing module 8 includes a telescopic bolt 803, a front fixing module 802 and a rear fixing module 801. The rear fixing module 801 is welded to the fixing module 8, and the front fixing module 802 is fixedly connected to the telescopic bolt 803. The telescopic bolt 803 is threadedly connected to the fixing module 8.

[0031] The fixed module 8 allows the cup opening 7 and the hydraulic jack assembly 3 to first determine the position where the steel column 5 needs to be fixed and corrected. This avoids the problem that after the steel column 5 is placed in the cup opening 7, the jacks have no fixed points and are prone to slipping. Furthermore, after the steel column 5 is fixed, it does not need to be fixed with a steel frame by welding, unlike traditional correction. It can also be reused, thereby improving work efficiency and safety.

[0032] The top of the hydraulic fixing pipe 302 is equipped with a hydraulic oil pipe 2, which is engaged with the hydraulic fixing pipe 302. The end of the hydraulic oil pipe 2 is equipped with a hydraulic output pipe 4, which is engaged with the hydraulic oil pipe 2. The top of the hydraulic fixing pipe 302 of each hydraulic jack assembly 3 is connected to a hydraulic oil pipe 2, and the hydraulic oil pipes 2 are interconnected. Each hydraulic jack assembly 3 is connected to a hydraulic oil pipe 2, and all hydraulic oil pipes 2 are connected to the same hydraulic output pipe 4. This allows the hydraulic jacks 301 to apply pressure synchronously, preventing the steel column 5 from tilting due to uneven force.

[0033] Each side of the steel column 5 is fixed by two hydraulic jacks 3, and each hydraulic jack 3 has two hydraulic jacks 301. By using the 16 hydraulic jacks 301 set around the steel column 5, the hydraulic pump 1 adjusts the steel column 5 in different directions within the cup 7, making the steel column 5 more firmly fixed and improving the safety of use. The hydraulic output pipe 4 is located on the top of the mobile hydraulic operating platform 6 and is fixedly connected to the mobile hydraulic operating platform 6. The top of the mobile hydraulic operating platform 6 is equipped with a hydraulic pump 1, and the hydraulic pump 1 is fixedly connected to the mobile hydraulic operating platform 6. When carrying out operations, the mobile hydraulic operating platform 6 can be placed in a safe construction area, which is convenient for carrying and operation while ensuring the safety of construction personnel.

[0034] In summary: The steel column 5 is hoisted into the cup opening 7, and hydraulic jacks 3 are placed in the designed grouting gap to support the sides of each steel column 5. There are two hydraulic jacks 3 on each side of the steel column 5, and the hydraulic jacks 3 on each side are fixedly connected by sliding components 9. Each hydraulic jack 3 has two hydraulic jacks 301, for a total of eight hydraulic jacks 3 and sixteen hydraulic jacks 301.

[0035] Before commencing work, confirm the fixed positions and place the hydraulic jacks 3 on each side inside the cup opening 7. Adjust the hydraulic jacks 301 in place using the sliding components 9 (up, down, left, and right). Then, use the telescopic bolts 803 of the fixing module 8 to initially fix the cup opening 7 to the hydraulic jacks 3. Using the hydraulic pump 1 on the movable hydraulic operating platform 6, press each pre-set hydraulic jack 301 to initially fix the steel column 5 to the cup opening 7. According to the inclination of the steel column 5 measured by the surveyor, press or release the corresponding hydraulic jacks 301 to push the steel column 5 to the appropriate position. After confirming the position, reconfirm the fixation using the telescopic bolts 803 of the fixing module 8. Then, proceed with the following construction arrangements.

[0036] This effectively solves the problem that mobile cranes or tower cranes cannot dismantle the steel column 5 in a timely manner during the straightening process, improving the straightening efficiency of the steel column 5 and reducing the frequency of straightening. It also solves the problem of using a lot of manpower to weld vertical jack supports onto the steel column 5 during traditional straightening, protecting the overall thermal effect zone of the steel column 5 from damage. Reducing the need to weld supports onto the steel column 5 saves material and labor costs, and also saves electricity.

[0037] Hydraulic jacks 301 are used between the cup opening 7 and the steel column 5. The hydraulic jacks 301 are positioned around the cup opening 7, firmly anchoring the steel column 5. This eliminates the need for manual labor to work directly at the base of the steel column 5, significantly reducing safety hazards. Furthermore, the hydraulic jacks 301 on each side can be adjusted in groups and distances under the action of the sliding component 9, allowing for omnidirectional operation and adjustment according to actual conditions, making the steel column 5 straightening more precise and efficient. This avoids limitations in usage and improves flexibility. The fixing module 8 allows the cup opening 7 and the hydraulic jack assembly 3 to pre-determine the position of the steel column 5 to be fixed and straightened, avoiding the problem of the steel column 5 being placed in the cup opening 7 without a fixed point for the jacks, which could easily slip off. Moreover, after the steel column 5 is fixed, it does not require the welding of a steel frame for fixation as in traditional straightening methods, and can be reused, thereby improving work efficiency and safety.
