Technical Field

[0001] The utility model relates to the technical field of mechanical engineering equipment, in particular to a height adjustment device for a pre-circular pipe column lengthening group. Background Art

[0002] In the mechanical engineering and construction industries, the extension and pairing of round tube steel columns is an important link, especially in high-rise and super-high-rise steel structure buildings. These buildings often need to connect and combine multiple sections of round tube steel columns to meet the requirements of building height. However, the traditional connection method usually relies on crane hoisting and manual adjustment by workers. Although this method is feasible, it has many problems in actual operation.

[0003] During the crane hoisting process, it is difficult to accurately dock the round tube steel column at one time due to the shaking of the hook. Workers often need to make repeated adjustments in multiple directions, which not only increases the complexity of the operation, but also greatly reduces work efficiency. At the same time, crane hoisting also has safety hazards, especially when working at high altitudes, which poses a certain threat to the safety of workers. In addition, the traditional docking method lacks flexibility and precision. During the docking process, it is difficult to fine-tune the height of the round tube steel column, which to a certain extent affects the accuracy and quality of the docking. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides a height adjustment device for pre-circular pipe column lengthening group, such as Figure 1-Figure 4 As shown, it includes a base 1, jacks 2 are installed on both sides of the base 1, a telescopic support seat 3 is connected to the top of the base 1 for supporting and positioning the round tube, a roller 4 is installed on the top of the telescopic support seat 3, the telescopic support seat 3 includes a lifting tube 31 of a cylindrical structure, a support plate 32 is installed on the top of the lifting tube 31, a vertical plate 33 is installed in the middle of the top of the support plate 32, and the rollers 4 are installed at both ends of the vertical plate 33. The telescopic support seat 3 is driven by the jack 2 to perform smooth lifting and lowering to ensure the accuracy during docking.

[0022] In this embodiment, the base 1 includes a bottom plate 12 , a positioning sleeve 11 is welded and fixed in the middle of the top of the bottom plate 12 , and the lifting tube 31 is plugged and matched with the positioning sleeve 11 to facilitate the lifting and lowering action of the lifting tube 31 .

[0023] Specifically, an arc-shaped limiting groove 331 is provided on the top of the vertical plate 33, and mounting holes are provided at both ends of the vertical plate 33. The axis of the roller 4 is rotatably connected to the vertical plate 33 through a bearing to position the end of the round tube.

[0024] Furthermore, the vertical plate 33 and the roller 4 are connected and fixed by bolts, nuts and washers, so as to facilitate the locking and disassembly of the roller 4.

[0025] Furthermore, vertical supports 13 are installed at the bottom of both ends of the base plate 12, and a transverse support 14 is provided at the top of the vertical support 13. The bottom end of the jack 2 is fixed to the top of the transverse support 14, and the top end of the jack 2 abuts against the lower surface of the support plate 32. One side of the transverse support 14 is welded and fixed to the outer wall of the positioning sleeve 11, and the top and bottom supports of the jack 2 are positioned by the vertical supports 13 and the transverse supports 14.

[0026] Furthermore, an anti-skid pad is installed on the outer wall of the roller 4 to achieve an anti-skid effect.

[0027] Furthermore, the outer wall size of the lifting tube 31 is matched with the inner wall size of the positioning sleeve 11 , so that the lifting tube 31 can be lifted and lowered flexibly.

[0028] Furthermore, the top diameter of the lifting tube 31 is smaller than the bottom width of the support plate 32 , so as to facilitate stable support of the support plate 32 .

[0029] When the height adjustment device for the pre-circular tube column extension group of the utility model is used, the circular tube column to be extended is first placed on the telescopic support seat 3, specifically on the roller 4. The design of the roller 4 allows the circular tube column to roll easily, which is convenient for adjusting the rotation of the circular tube and then adjusting the docking position. The roller 4 is installed at both ends of the vertical plate 33, and the vertical plate 33 is fixed on the support plate 32. Such a structure allows the roller 4 to provide stable support while maintaining flexibility.

[0030] Next, the height of the telescopic support seat 3 is adjusted by operating the jack 2. The bottom end of the jack 2 is fixed on the horizontal support 14, and the horizontal support 14 is firmly connected to the bottom plate 12 of the base 1 through the vertical support 13. When the jack 2 is working, its top end will push the support plate 32 up and down, thereby driving the entire telescopic support seat 3 to move up and down. Since the lifting tube 31 is plugged into the positioning sleeve 11 on the base 1, this plug-in structure ensures the stability and accuracy of the lifting process.

[0031] In the process of adjusting the height, the relative position of the round pipe column and the docking component can be observed to accurately control the lifting and lowering of the jack 2 to achieve the best docking height. At the same time, the anti-skid pad installed on the outer wall of the roller 4 can ensure that the round pipe column will not slide during the docking process, further enhancing the stability and safety of the operation.

[0032] Finally, it should be noted that the electronic components in the jack 2 in this embodiment are all universal standard parts or parts known to technical personnel in this field, and their structures and principles can be known to technical personnel in this field through technical manuals or through conventional experimental methods. In the idle part of this device, all the above-mentioned electrical components are connected respectively through wires. The specific connection means should refer to the working sequence between the electrical components in the above-mentioned working principle to complete the electrical connection, which are all well-known technologies in the field.

[0033] The above shows and describes the basic principle, main features and advantages of the utility model.
