Description

Technical Field

[0001] The utility model relates to a multi-directional jack beam adjusting device, which relates to the field of steel structure manufacturing. Background Technique

[0002] In the process of manufacturing steel structure bridges, in order to ensure the smooth connection of the bridge position and improve the overall manufacturing accuracy, it is necessary to perform matching assembly on the beam segments, and the assembly adjustment accuracy needs to be controlled within the millimeter level. Due to the large size and heavy weight of the beam segments themselves, it is difficult to adjust.

[0003] The traditional adjustment method is to weld lifting lugs on the beam segments, and use lifting equipment to lift the beam segments and then perform adjustment. This adjustment method requires large lifting equipment (such as gantry cranes) to be installed at the assembly site, and the production, installation, and removal of lifting lugs are required. This adjustment method causes limitations in the assembly site, increases and wastes raw materials, and the installation and removal of lifting lugs will also cause certain damage to the base metal of the beam segments. The traditional jack beam adjustment is generally for up and down adjustment, and lateral adjustment cannot be performed due to the lack of force application points. Therefore, there is an urgent need for a new type of steel structure bridge fine adjustment device to achieve three-directional beam adjustment in the x-axis, y-axis, and z-axis during beam segment assembly.

A sliding space is formed between the screw jack 12 and the sliding assembly, and the sliding assembly is driven by the screw jack 12, and the movement in the X-axis direction and the Y-axis direction is realized through the screw jack 12.

[0024] In the present utility model, by providing the support main body, the hydraulic jack 13, the screw jack 12, the sliding assembly, the fixing assembly and the forklift frame 4, the following are achieved:

[0025] Multi-directional adjustment: By combining the use of the hydraulic jack and the screw jack, the device can realize movement in the X-axis direction, the Y-axis direction and the Z-axis direction, increasing the flexibility and accuracy of beam adjustment.

[0027] Strong adaptability: It can adapt to beams of different sizes and shapes. By adjusting the screw jack and the hydraulic jack, different beam adjustment requirements can be met.

[0028] The described support main body includes a steel base 1, a steel top plate 2, I-beams 3, a truss 5, diagonal braces 6 and cross braces 7. The steel top plate 2 and the steel base 1 are arranged parallel to each other. The I-beams 3 are installed between the steel base 1 and the steel top plate 1 to connect the steel base 1 and the steel top plate 2 together. The truss 5 is arranged on one side of the steel base 1. The cross braces 7 are symmetrically installed on both sides of the I-beams 3. One diagonal brace 6 is welded between each cross brace 7 and the truss 5. The two diagonal braces 6 are arranged parallel to each other. On the upper part of each cross brace 7, there is a forklift frame 4, and the cross brace 7 supports the forklift frame at the same time.

[0029] Using a steel base and a steel top plate, as well as I-beams as the main load-bearing members, improves the load-bearing capacity and stability; connecting the steel base and the top plate through I-beams enhances the rigidity of the overall structure and reduces deformation under load.

[0030] The design of the truss 5 and the diagonal braces 6 optimizes the space utilization, provides additional support points, and at the same time maintains the compactness of the structure; at the same time, the truss 5 is also used for installing a hydraulic pump.

[0031] Several steel lateral reinforcing ribs 15 and steel vertical reinforcing ribs 8 are also installed on the I-beams 3.

[0032] The described sliding assembly includes a slider 16 and a stop block 14. The slider 16 is square-shaped and is slidably installed on the steel top plate 2. One stop block 14 is installed on each of the four sides of the slider 16, and each stop block 14 corresponds to a screw jack 12; the hydraulic jack 13 is installed in the middle of the slider 16.

[0033] Each fixing assembly includes a reaction frame base 9, a baffle 10 and a baffle reinforcing rib 11. The reaction frame base 9 is arranged on the steel top plate 2. One end of the reaction frame base 9 is welded to the steel top plate 2, and the other end extends outward; the baffle 10 is perpendicularly welded to the other end of the reaction frame base 9. The baffle reinforcing rib 11 is welded between the outer side of the baffle 10 and the reaction frame base 9. The screw jack 12 is installed on the inner side of the baffle 10.

[0034] In the fixing assembly, the setting of the baffle reinforcing rib improves the strength of the baffle, enables the fixing assembly to bear greater force, and thus improves the load-bearing capacity of the overall structure.

[0035] The compact design of the reaction frame base, the baffle and the baffle reinforcing rib minimizes the space occupied by the fixing assembly while maintaining high structural performance.

[0036] A screw jack is installed inside the baffle, which provides a reverse acting force and a stable support point for the operation of the screw jack, ensuring the stability and safety of the screw jack during operation.

[0037] Several partition plates 17 are also welded on the I-beam 3, and all the partition plates 17 are uniformly arranged along the circumferential direction of the I-beam 3 and are all close to the upper end of the I-beam 3.

[0038] A steel vertical stiffener 8 is provided at the lower part of each reaction frame base 9, and the reaction frame base 9 is supported by the steel vertical stiffener 8.

[0039] It also includes a displacement sensor for measuring the displacement distance of the stop block 14, and the displacement sensor, the hydraulic jack 13 and the screw jack 12 are all connected to the control panel.

[0040] The working principle of the present utility model: When in use, insert the fork of the forklift into the forklift frame 4, lift it and place it under the required position. Then place the hydraulic jack 13 on the slider 17 and place the hydraulic pump on the truss 1. The hydraulic pump pumps pressure to the hydraulic jack 13 to lift the heavy object, completing the movement in the z-axis direction. Then, by adjusting the screw jacks 9 at different positions, the screw jacks 9 are made to abut against the stop block 11 and the baffle 8 to drive the stop block 14, completing the movement in the x-axis direction and the y-axis direction. Position sensors are installed at the tops of the screw jacks 9 in each direction to accurately control the displacement amount and achieve precise adjustment.

Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
