Description

Technical Field

[0001] This utility model relates to the field of steel structure positioning technology, specifically a positioning mechanism for a steel structure straightening device. Background Technology

[0002] In the field of steel structure manufacturing and installation, precise alignment of steel structures is crucial for ensuring the overall stability, safety, and functionality of the structure. During production, transportation, and installation, steel structures are highly susceptible to deformation due to various factors such as welding stress, transportation collisions, and installation errors. This deformation can include, but is not limited to, bending, twisting, and localized dents. If these deformations are not corrected promptly and accurately, the steel structure cannot be assembled according to design requirements, affecting the overall structural performance of the building and potentially leading to serious safety accidents.

[0003] Existing steel structure straightening methods and devices have limitations in practical applications. Some traditional straightening devices lack effective positioning mechanisms, making it difficult to accurately determine the straightening position during the straightening operation. This results in a high degree of blindness in the straightening process, leading to low straightening efficiency and difficulty in guaranteeing straightening accuracy. It often requires repeated adjustments, increasing the consumption of manpower, material resources, and time. Therefore, a positioning mechanism for steel structure straightening devices is proposed to solve the above problems. Utility Model Content

This results in a high degree of blindness in the straightening process, leading to low straightening efficiency and difficulty in guaranteeing straightening accuracy. It often requires repeated adjustments, increasing the consumption of manpower, material resources, and time. Therefore, this invention proposes a positioning mechanism for steel structure straightening devices.

The front end of the rectangular frame has two sliding grooves, and the inner sides of the two sliding grooves are slidably connected to two sliding mechanisms. A rectangular alignment base is detachably connected between the four sliding mechanisms. A positioning ring is detachably connected to the front end of the rectangular alignment base by bolts. The positioning ring is located in the middle of the front side of the rectangular alignment base, and a positioning through hole is provided on the inner side of the positioning ring. An auxiliary alignment mechanism is provided on the rectangular alignment base.

Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] In the embodiments, by Figure 1-3 A positioning mechanism for a steel structure straightening device is provided, comprising two base feet 1, the top ends of which are fixedly connected to a rectangular frame 2. Two sliding grooves 3 are provided at the front end of the rectangular frame 2, and two sliding mechanisms 4 are slidably connected to the inner sides of the two sliding grooves 3. A rectangular alignment base 5 is detachably connected among the four sliding mechanisms 4. A positioning ring 6 is detachably connected to the front end of the rectangular alignment base 5 by bolts. The positioning ring 6 is located at the middle of the front side of the rectangular alignment base 5. A positioning through hole 7 is provided on the inner side of the positioning ring 6. An auxiliary alignment mechanism 8 is provided on the rectangular alignment base 5.

[0015] With the above setup, the shape of the positioning through-hole 7 is adapted to the shape of the steel structure to be corrected. Since the front end of the rectangular frame 2 has a groove 3, the sliding mechanism 4 connected to the rectangular alignment base 5 can move within the groove 3. The operator can easily push the rectangular alignment base 5, allowing it to move smoothly left and right in the plane via the sliding mechanism 4. The purpose of this step is to roughly align the positioning ring 6 in the middle of the base with the target point on the steel structure that needs correction. The operator activates or observes the auxiliary alignment mechanism 8, and fine-tunes the position and angle of the rectangular alignment base 5 according to the emitted light spot or indication. For example, by slightly pushing the base, the laser point is precisely hit on the target correction point. This process ensures that the central axis of the positioning ring 6 is accurately aligned with the target point. Once the positioning through-hole 7 of the positioning ring 6 is accurately aligned, the operator locks the locking device on the sliding mechanism 4, such as the locking bolt (not shown in the figure but present), to completely fix the position of the rectangular alignment base 5. Finally, the piston rod of the correction tool, such as a hydraulic jack, is passed through the precisely positioned positioning through-hole 7. At this point, the force application center line of the straightening tool is precisely aligned with the target point of the steel structure to be straightened. Activating the straightening tool allows for the application of straightening force. Due to accurate positioning, the straightening force can be precisely applied to the predetermined position, avoiding slippage or secondary deformation and ensuring the straightening effect. This device combines the coarse adjustment of the slide 3 with the fine adjustment of the auxiliary alignment mechanism 8, achieving high-precision point positioning in a two-dimensional plane. This ensures the accuracy of the straightening force application point, thereby directly improving the quality and controllability of steel structure straightening.

[0016] Reference Figure 1-3 The sliding mechanism 4 includes a slider 41, which is slidably connected to the inner side of the slide groove 3, and a mounting rod 42 is fixedly connected to the front end of the slider 41. Through the above structural design, the cooperation between the slide groove 3 and the slider 41 ensures that the movement is strictly linear, avoiding wobbling and offset, and laying the foundation for precise positioning.

[0017] Reference Figure 1-3Among them, a threaded sleeve 9 is fixedly connected to the outer side of the mounting rod 42, and a mounting piece 10 is sleeved on the outer side of the threaded sleeve 9. Two nuts 11 are threadedly connected to the outer side of the threaded sleeve 9, and the mounting piece 10 is located between the two nuts 11. The rectangular alignment base 5 is fixedly connected to the rear end of the mounting piece 10. With the above structural setup, achieving perfect alignment with zero error in mechanical installation is difficult. Minor misalignment may exist between the four mounting points on the rectangular alignment base 5 and the front ends of the four mounting rods 42. Through the connection of the threaded sleeve 9 and two nuts 11, the mounting piece 10 is "flexible" to the mounting rods 42 before the nuts 11 are finally tightened. The operator can slightly adjust the angle or position of the mounting piece 10 to better fit the connection surface of the rectangular alignment base 5, thereby compensating for minor manufacturing or assembly errors. Once the position is properly adjusted, tightening the two nuts 11 will firmly clamp the mounting piece 10 onto the threaded sleeve 9 from both sides. This "two-way locking" structure instantly transforms the previous "flexible" connection into a rigid connection, ensuring that the connection points will not loosen under working loads and providing strong rigid support.

[0018] Reference Figure 1-3 The auxiliary alignment mechanism 8 includes a fixing plate 81. Two fixing plates 81 are fixedly connected to the rear end of the rectangular alignment base 5. The two fixing plates 81 are located at the middle of the left and right sides of the rectangular alignment base 5, respectively. Fixing rods 82 are fixedly connected to the inner side of the two fixing plates 81. A laser emitter 83 is fixedly connected to the rear end of the left fixing rod 82, and a laser receiver 84 is fixedly connected to the rear end of the right fixing rod 82. With the above structural setup, before initiating the correction operation, the operator first turns on the laser emitter 83. The laser emitter 83 emits a visible laser beam, which is horizontally directed towards the laser receiver 84 opposite. Ideally, when the entire device is perfectly aligned, the laser beam should precisely hit the center of the laser receiver 84. The operator places the entire positioning device near the steel structure. They first visually inspect and manually push the device or adjust the rectangular alignment base 5 (via the sliding mechanism 4) to roughly align the positioning through-hole 7 of the positioning ring 6 with the target point on the steel structure that needs correction. The operator then shifts their gaze away from the positioning ring 6 and closely observes the position of the laser spot on the laser receiver 84. If the laser spot does not fall on the center of the receiver, it indicates that the axis of the positioning ring 6 is tilted. The operator then fine-tunes the position of the rectangular alignment base 5 using the sliding mechanism 4 until the laser spot appears on the receiver. The operator observes the specific position of the laser spot on the receiver's target. If the spot is off-center to the left or right, it indicates that the base has been horizontally deflected (i.e., the axis of the positioning ring 6 is not perpendicular to the correction plane). The operator needs to fine-tune the horizontal angle of the rectangular alignment base 5 to ensure the laser spot is positioned on the horizontal centerline of the target. If the laser spot is too high or too low, it indicates that the rectangular alignment base 5 may have inconsistent height, resulting in a pitch angle. In this case, it may be necessary to fine-tune the nut 11 on the mounting rod 42 to level the base and position the laser spot on the vertical centerline of the target. This fine-tuning process is iterative and may require repeated adjustments until the laser spot precisely falls on the crosshair center of the laser receiver 84. When the laser spot is stable at the center of the receiver, it means that the "optical reference line" connecting the laser emitter 83 and the laser receiver 84 is in an ideal state. Since these two components are rigidly connected to the rectangular alignment base 5 via the fixing rod 82 and the fixing plate 81, this optical reference line strictly defines the spatial direction of the central axis of the positioning ring 6. At this point, the axis of the positioning ring 6 is precisely aligned with the correction target point. The operator immediately locks all the locking devices of the sliding mechanism 4 to completely fix the rectangular alignment base 5. The correction tool (such as a hydraulic jack) is then passed through the precisely aligned positioning through hole 7 to begin applying force for correction. Because of the extremely high alignment accuracy of the axis, the direction and point of application of the corrective force are controllable and accurate.
