Abstract
Description
Technical Field
[0001] This utility model relates to the field of bridge deck drilling equipment technology, specifically to a template component that assists in drilling a group of holes in bridge decks. Background Technology
[0002] In steel structure bridges, steel beams are mainly composed of main truss upper and lower chords, web members, transverse and longitudinal beams, bridge deck, secondary truss upper chords, and secondary truss diagonal braces. The manufacturing process of the upper chord requires addressing the drilling issues of the upper chord vertical plates and node plates, while the manufacturing process of the lower chord requires addressing the drilling issues of the lower chord vertical plates and node plates. Different stress conditions lead to different cambers in the members, resulting in different system lines for the same project. In some projects, the entire truss is arched and laid out by elongating the upper chord members, shortening the lower chord members, and keeping the vertical members the same length, thus changing the included angle of the system lines. This results in different system line angles for the upper and lower chords, creating a huge workload for the production of large, covered templates. This places extremely high demands on the drilling workers in the workshop in selecting holes and making templates, significantly increasing the probability of drilling incorrect holes. Therefore, providing a template component that can adapt to the processing of positioning holes for different bridge decks is of great significance for improving the manufacturing efficiency and accuracy of bridge members.

[0027] Please see Figure 1 and Figure 2 As shown in the figure, an embodiment of this utility model proposes a template assembly for assisting in drilling a group of holes in a bridge slab. This template assembly includes a panel 1 that mimics the shape of a bridge slab and a fixing frame 2. The fixing frame 2 is fixed to the panel 1, providing structural strength support for the panel 1. Both the panel 1 and the fixing frame 2 have shapes that mimic the shape of a bridge slab, wherein the fixing frame 2 is a lightweight frame structure. As a preferred embodiment, in this utility model embodiment, the fixing frame 2 is made of lightweight materials such as nylon or aluminum alloy. Figure 3 As shown, panel 1 has a first group of holes 11, a second group of holes 12, a third group of holes 13, a fourth group of holes 14, a fifth group of holes 15, and a semi-circular opening 16. The third group of holes 13 and the fourth group of holes 14 are symmetrically located on either side of the centerline of the semi-circular opening 16, forming an included angle, and their lower ends are connected to the semi-circular opening 16. Figure 3 As shown, the first hole group window 11, the second hole group window 12, and the fifth hole group window 15 are arranged horizontally along a straight line. The panel 1 has multiple linearly distributed panel grooves 17 at positions along this straight line, and the fixing bracket 2 also has multiple linearly distributed panel grooves 17 at the first centerline positions corresponding to the third hole group window 13 and the fourth hole group window 14. Wherein, as... Figure 1 and Figure 9 As shown, each panel recess 17 is equipped with a system line angle fine-tuning mechanism 6 for connecting the guide rail 100. An externally mounted drilling device is mounted on the guide rail 100, allowing the drilling device to move along the guide rail 100 to different hole groups on the panel 1. Specifically, when the bridge deck arches, causing a change in the drilling angle, the system line angle fine-tuning mechanism 6 can adjust the angle of the guide rail 100 to adapt the drilling angle of the drilling device to the arched bridge deck. For example... Figure 9As shown in the diagram, line "A" represents the working state of the guide rail 100 when the bridge deck is not arched. At this time, the drilling system line angle is 0°, and the guide rail 100 does not need to be adjusted in terms of system line angle, remaining in the state shown in line "A". Line "B" represents a typical working state of the guide rail 100 when the bridge deck is arched. At this time, the drilling system line angle has a small change compared to line "A", exhibiting a small upward deflection. When this angle change occurs, the guide rail 100 needs to be adjusted accordingly by the system line angle fine-tuning mechanism 6, so that the drilling device on the guide rail 100 adapts to the current angled drilling. Similarly, line "C" shows another typical working state of the guide rail 100 in the arched state of the bridge deck. At this time, the drilling system line angle has a small change compared to line "A," exhibiting a small downward deflection. When this angle change occurs, the guide rail 100 needs to be adjusted accordingly using the system line angle fine-tuning mechanism 6, so that the drilling device on the guide rail 100 adapts to the current angled drilling. By adjusting the guide rail 100 slightly using the system line angle fine-tuning mechanism 6, this invention can complete the drilling of positioning holes for the bridge deck in the arched state.
[0028] To improve the adaptability and positioning of the template components of this utility model, such as Figure 1 , Figure 3 and Figure 4 As shown, the fixed frame 2 has adjustable positioning clamps 3 at both ends. The positioning clamps 3 at both ends can be positioned closer or further apart. By adjusting the positioning clamps 3, this invention can be applied to bridge slabs of different lengths. In addition, the positioning clamps 3 also have a workpiece positioning function. The two positioning clamps 3 can be simultaneously extended and retracted on both sides. Combined with the self-adaptive characteristics of the movable template assembly, the center of the positioning clamps 3 can be aligned with the center of the bridge slab. To improve the mobility of the template assembly of this invention, such as... Figure 1 and Figure 5 As shown, the bottom of the fixing frame 2 is provided with multiple rows of universal rollers 4 along its length. These universal rollers 4 allow the entire template device to be moved to the side of the bridge slab where the positioning holes need to be drilled. Specifically, as shown... Figure 2 and Figure 5 As shown, the bottom of the mounting bracket 2 is provided with a roller groove 26, in which two parallel universal rollers 4 are installed. Figure 1 , Figure 3 and Figure 7 As shown, panel 1 has a shaft hole 18 at the center of the corresponding semi-circular opening 16, and a motor mounting base 5 is provided on the back side. The motor mounting base 5 is used to install an external guide rail adjustment fixture, which is used to adjust the angle of the guide rail.
[0029] Further, in the preferred embodiment of the present utility model, as Figure 6 shown, the system line angle fine-tuning mechanism 6 includes an arc-shaped slide rail 61 fixed in the panel groove 17 and a slider 62 slidably connected to the arc-shaped slide rail 61, wherein the guide rail 100 is fixedly connected to the slider 62. As Figure 9 shown, the centers of the arc-shaped slide rails 61 of the system line angle fine-tuning mechanisms 6 at each position are all oriented towards the shaft hole 18. As Figure 1 and Figure 3 shown, the first hole group window 11, the second hole group window 12, and the fifth hole group window 15 are all "field"-shaped windows, and the third hole group window 13 and the fourth hole group window 14 are both "square"-shaped windows. As Figure 2 shown, the fixing frame 2 is of a frame structure, and at the positions corresponding to the first hole group window 11, the second hole group window 12, and the fifth hole group window 15 are adapted "field"-shaped frames. The fixing frame 2 is provided with a horizontally linearly extending straight frame 21 on the connection line of the two ends corresponding to the semi-circular opening 16. The straight frame 21 is respectively formed with inclined frames 22 at the first midline positions of the third hole group window 13 and the fourth hole group window 14. The straight frame 21 is provided with straight frame break openings 211 at the two ends corresponding to the semi-circular opening 16, and the inclined frames 22 are provided with inclined frame break openings 221 at the positions corresponding to the semi-circular opening 16. The straight frame break openings 211 and the inclined frame break openings 221 are used for the external supporting guide rail adjusting tooling to pass through when rotating, so as to cooperate with the guide rails at different positions. Specifically, in the embodiment of the present utility model, the guide rail 100 is installed at four positions, which are respectively distributed on Figure 1 the horizontal midline where the left-side first hole group window 11 and the second hole group window 12 are located, Figure 1 the horizontal midline of the right-side fifth hole group window 15, and the first midline positions of the third hole group window 13 and the fourth hole group window 14.
[0030] Further, in the preferred embodiment of the present utility model, as Figure 4 shown, the positioning clamping plate 3 has a protruding clamping portion 31 facing the side of the bridge plate, and guide portions 32 extending along the length direction of the fixing frame 2 are formed at the upper and lower ends on the side opposite to the bridge plate. As Figure 2 shown, two并列的开口槽23 are respectively formed at the upper and lower end positions of the left and right ends of the fixing frame 2. Among them, the guide portion 32 is slidably installed in one of the opening slots 23, and a telescopic cylinder seat 33 is provided in the other opening slot 23. A telescopic cylinder is provided in the telescopic cylinder seat 33, and the guide rod of the telescopic cylinder is fixedly connected to the positioning clamping plate 3. When the guide rod of the telescopic cylinder extends and retracts, it drives the guide portion 32 to move in the corresponding opening slot 23, thereby adjusting the distance between the two end positioning clamping plates 3.
[0031] Further, in the preferred embodiment of the present utility model, as Figure 2 and Figure 3 As shown, the mounting bracket 2 has multiple electromagnet mounting holes 25, and the panel 1 has openings 19 corresponding to the electromagnet mounting holes 25. The electromagnets installed in the electromagnet mounting holes 25 can be magnetically fixed to the aligned bridge plate to position the template assembly and the bridge plate, preventing displacement during subsequent drilling.
[0032] Furthermore, in a preferred embodiment of this utility model, such as Figure 8 As shown, the template assembly of this utility model includes two panels 1 with the same structure and two fixing frames 2 with the same structure. The two fixing frames 2 are fixed to form an integral support structure, and the panels 1 are respectively located on the front and back surfaces of the integral support structure.
