Description

Technical Field

[0001] The utility model relates to the technical field of bridge installation, in particular to a steel structure bridge installation mechanism. Background Art

[0002] The installation of steel bridges involves assembling the various steel structures. During assembly, the installation location must first be measured on the primary steel components, and then the secondary steel components are installed at that location. Because bridges are linear structures, installation is typically segmented, meaning that the same structural components are assembled between each construction section. This means that the assembly locations of these components remain the same, eliminating the need for repeated measurements. However, existing construction methods lack a way to preserve these assembly locations, requiring workers to repeatedly measure and locate them.

[0003] To this end, the utility model proposes a steel structure bridge installation mechanism with a memory positioning function. Utility Model Content

Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0033] like Figure 1-6 As shown, the steel structure bridge installation mechanism proposed by the present invention. Specifically,

[0034] like Figure 1-3 As shown, it includes a main steel positioning bar 3 and a pair of first positioning mechanisms 4 installed at both ends of the main steel positioning bar 3. The two first positioning mechanisms 4 are adjusted on the main steel positioning bar 3 to position the main steel 1. Specifically, the first positioning mechanism 4 includes a positioning arm 41 and a first screw shaft 42. The first screw shaft 42 is rotatably connected to the main steel positioning bar 3. One end of the positioning arm 41 is fixedly connected to a threaded sleeve 411 that is screwed onto the first screw shaft 42. When the first screw shaft 42 is rotated, the threaded engagement between the threaded sleeve 411 and the first screw shaft 42 can cause the two positioning arms 41 to move in opposite directions. When the two are close to each other, they can clamp the main steel 1.

[0035] like Figure 1 and Figure 4 As shown, it includes a second positioning mechanism 5 installed on the positioning arm 41, the second positioning mechanism 5 clamps and fixes the auxiliary steel part 2 and positions the auxiliary steel part 2 by moving axially along the main steel part positioning strip 3. Specifically, the second positioning mechanism 5 includes a clamp assembly 51 for clamping and fixing the auxiliary steel part 2, a third screw shaft 52 having one end rotatably connected to the clamp assembly 51 and the other end screwed together with the positioning arm 41, and a semi-threaded light rod 53 having one end fixedly connected to the clamp assembly 51 and the other end movably passing through the positioning arm 41. The clamp assembly 51 includes a clamp base 511, a clamp plate 512 that slides horizontally on the upper surface of the bottom plate of the clamp base 511, a second screw shaft 513 having one end rotatably connected to the clamp plate 512 and the other end screwed together with the clamp base 511, and a guide light rod 514 having one end fixedly connected to the clamp plate 512 and the other end movably passing through the clamp base 511. When the third screw shaft 52 is rotated, the horizontal position of the clamp assembly 51 can be adjusted by screwing the third screw shaft 52 and the positioning arm 41, thereby changing the assembly position of the auxiliary steel component 2 on the main steel component 1;

[0036] In addition, reference Figure 4-5, also includes an assembly point memory mechanism 6, which realizes the function of storing positioning points by restricting the translation of the second positioning mechanism 5. Specifically, the assembly point memory mechanism 6 includes a threaded sleeve 61 and a stopper 62. One end of the semi-threaded polished rod 53 is a smooth surface, which is used for movable connection with the positioning arm 41, and the other end is provided with an external thread, and the threaded sleeve 61 is provided with an internal thread matching it. The threaded sleeve 61 is coaxially connected to the end of the positioning arm 41, and the inner annular surface of the stopper 62 is fixedly connected to the positioning slider 621, and the outer annular surface of the semi-threaded polished rod 53 is provided with a positioning groove 531 for the positioning slider 621 to slide horizontally. When the threaded sleeve 61 is rotated, the threaded sleeve 61 drives the stopper 62 to translate axially along the semi-threaded polished rod 53 by screwing with the thread of the external thread on the semi-threaded polished rod 53. Since the semi-threaded polished rod 53 moves along with the position adjustment of the clamp assembly 51 when the third screw shaft 52 is rotated, the stopper 62 contacts the positioning arm 41, terminating the movement. If the termination point is the assembly point of the auxiliary steel component 2 and the main steel component 1, the stopper 62 can be quickly adjusted to the assembly point by determining whether it is blocked or not, without the need for repeated measurement and adjustment. In addition, the stopper 62 in this embodiment is a circular structure. In addition to the connection method in this embodiment, the stopper 62 can also be fixedly connected to the threaded sleeve 61 while removing the positioning slider 621 and the positioning slot 531. When the stopper 62 adopts a long strip-shaped structure that is prone to rotational obstruction, the rotation of the stopper 62 can be limited by the cooperation between the positioning slider 621 and the positioning slot 531.

[0037] In this embodiment, reference Figure 6 , also includes a height alignment substrate 7. The height alignment substrate 7 can be fixed to a flat surface such as the ground by bolt connection or other means. The main steel positioning bar 3 is fixed to the upper surface of one end of the height alignment substrate 7 by bolt connection or other means. The above embodiment can quickly determine the assembly position of the auxiliary steel part 2 and the main steel part 1 in the horizontal direction, but cannot guarantee that the two are consistent in the vertical direction. When the thickness values of the main steel part 1 and the auxiliary steel part 2 are the same, by opening a groove 71 on the upper surface of the height alignment substrate 7, the lower surface of the main steel part 1 and the upper surface of the bottom plate of the clamp base 511 are coplanar with the upper surface of the height alignment substrate 7, and the lower surface of the bottom plate of the clamp base 511 is coplanar with the upper surface of the groove 71, it can be ensured that the main steel part 1 and the auxiliary steel part 2 will not be misaligned in the vertical direction when assembled and positioned as described above;

[0038] In other embodiments, when the thickness values of the main steel part 1 and the auxiliary steel part 2 are different, the clamp assembly 51 can be designed as a height-adjustable structure, such as: the bottom plate of the clamp base 511 can be set to be vertically adjustable, which will not be elaborated here.

[0039] The working principle of this embodiment is as follows: When the auxiliary steel component 2 needs to be assembled with the main steel component 1 as shown in the figure, the main steel component 1 is first placed so that its height is aligned with the upper surface of the base plate 7. The first screw shaft 42 is rotated, and the two positioning arms 41 are brought closer together by the threaded engagement between the threaded sleeve 411 and the first screw shaft 42 to clamp the main steel component 1. The auxiliary steel component 2 is placed as shown in the figure, and the clamping plate 512 is translated by rotating the second screw shaft 513 to clamp the auxiliary steel component 2. Subsequently, the position where the auxiliary steel component 2 needs to be assembled is measured and marked on the main steel component 1. By rotating the third screw shaft 52, the clamp assembly 51 drives the auxiliary steel component 2 to the assembly position as described above. After completing the assembly of one group of main steel parts 1 and auxiliary steel parts 2, rotate the first screw shaft 42 and the second screw shaft 513 to remove the main steel parts 1 and the auxiliary steel parts 2 respectively. When assembling the next group of main steel parts 1 and auxiliary steel parts 2, there is no need to adjust the third screw shaft 52 as mentioned above. You can directly rotate the first screw shaft 42 and the second screw shaft 513 to fix the main steel parts 1 and the auxiliary steel parts 2 respectively.

[0040] In addition, when the types of the main steel part 1 and the auxiliary steel part 2 are replaced or the assembly position of the auxiliary steel part 2 on the main steel part 1 is changed, it is necessary to re-measure and draw lines and rotate the third screw shaft 52 for adjustment when switching back to the original assembly position. In this embodiment, the threaded sleeve 61 can be rotated to make the stopper 62 abut against the positioning arm 41 to record the adjustment position of the second positioning mechanism 5. Therefore, there is no need to measure and draw lines when switching back, and it is only necessary to rotate the third screw shaft 52 to make the stopper 62 abut against the positioning arm 41.

[0041] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art may make various alternative improvements and combinations to the above specific embodiments.
