Description

Technical Field

[0001] This invention relates to the field of bridge deck drilling technology for large members of steel structure bridges, specifically to an adjustable template that can meet the requirements of drilling positioning holes for ultra-large members of bridge decks of different specifications. 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. Except for orthotropic steel bridge decks, the truss members adopt box-shaped and I-shaped cross sections. Steel truss members and transverse and longitudinal beam members are manufactured in the workshop according to the basic procedure of "material cutting → processing → assembly → welding → straightening → drilling". After passing inspection, they undergo planar trial assembly. After passing the trial assembly inspection, they are disassembled into individual pieces, surface treated, painted, and shipped to the bridge site for assembly and installation on the bridge. A typical upper chord consists of integral node plates, vertical plates, top plates, bottom plates, diaphragms, bridge deck transverse beam joint plates, and web member joint plates. The maximum weight of a single member is approximately 50 tons, and manufacturing adopts an inverted assembly process. In the manufacturing process of the upper chord, it is necessary to solve the drilling problem of the upper chord vertical plates and node plates. The lower chord mainly consists of upper and lower horizontal plates, vertical plates, node plates, partitions, ribs, secondary truss diagonal brace joint plates, and crossbeam joint plates. The maximum weight of a single member is approximately 67 tons, and it is horizontally mounted on the side. The drilling problem for the lower chord's vertical plates and node plates needs to be solved during the manufacturing process.

[0003] Currently, some workshops have double-gantry CNC machine tools that can drill three holes at one end of a rod with a height of 5000mm and a width of 2500mm. This ensures that the longitudinal and lateral alignment of bolt holes on different planes is correct, enabling the drilling of bolt holes at both ends and nodes of the rod section. However, some frame gantry CNC machine tools can only handle rods with a height of 1950mm and a width of 2500mm. They cannot handle rods with a height greater than 2000mm, nor can they simultaneously drill bolt holes at both ends and nodes. For rods that cannot be drilled by gantry CNC machine tools, the common practice is to use a manual three-dimensional scribing method to drill positioning holes and then use a small template for drilling, or to create a large covering template to drill positioning holes and then use a small template for drilling. The manual three-dimensional marking and drilling method using small templates for positioning holes is difficult and limited by the operator's skill level, easily leading to excessive errors in the same hole group on the rod. Therefore, a method of making large, covering templates for drilling positioning holes and then connecting them with small templates is generally used to ensure the relative accuracy of the hole group on the rod. Currently, for projects requiring drilling of very large rods, large, covering templates are also generally made specifically for the project.

[0004] Currently, with the development and innovation of steel truss bridges in my country, the main beams of most truss bridges vary in shape and size. Due to limitations in manufacturing and transportation capacity, even if the main beams of some steel truss bridges are roughly the same size, differences in stress conditions lead to variations in the camber of the members and different member system lines within 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, thereby changing the included angle of the system lines. This results in different system line angles for the upper and lower chord members, creating a huge workload for the production of large-scale covered templates. With 41 different system line angles on two main trusses, if a pair of integrated templates is to be made, the hole clusters will be very dense, and the system lines at both ends of the template will also be very dense. This places extremely high demands on the drilling workers in the workshop in selecting holes and making templates, and greatly increases the probability of drilling incorrect holes. Summary of the Invention

[0046] Please see Figure 1 , Figure 2 and Figure 3As shown in the figure, an embodiment of the present invention proposes an integral template device for drilling positioning holes in ultra-large rods. This template device includes a movable template assembly, which consists of a template 1 and a frame 2. The template 1 is a contoured plate of a bridge slab to be drilled for positioning holes, and the frame 2 is a supporting structure that provides structural support for the template 1. Wherein, as... Figure 1 , Figure 2 and Figure 4 As shown, the template 1 includes a vertical template 11 and a node template 12. The vertical template 11 has multiple vertical hole groups 111 along its length, and the node template 12 has at least two node hole groups 121 located at different angles. Based on the system line angles of the upper and lower chords, positioning holes can be drilled at the corresponding node hole group windows 121. Figure 4 As shown, the node plate template 12 has an arc-shaped channel 122 that connects to the lower side of the node plate hole group window 121. The arc-shaped channel 122 is an arc-shaped through opening that runs through the front (facing the bridge plate side) and back (facing away from the bridge plate side) of the template component. Figure 4 As shown, the arc-shaped channel 122 is semi-circular, with the arch pointing upwards. Figure 1 , Figure 2 As shown, the vertical template 11 has a first fine-tuning guide rail 3 and a second fine-tuning guide rail 4 located at the left and right ends of the arc-shaped channel 122 along its length. The first fine-tuning guide rail 3 is connected to the corresponding end of the arc-shaped channel 122 at the end near the node plate template 12, and the second fine-tuning guide rail 4 is also connected to the corresponding end of the arc-shaped channel 122 at the end near the node plate template 12. Figure 1 and Figure 2 As shown, the first fine-tuning guide rail frame 3 has a movable drill sleeve device 5 on the guide rail facing the bridge slab. The drill sleeve device 5 is used to position the location where drilling is required, so as to facilitate precise drilling by the drill bit. In order to facilitate the automatic movement of the drill sleeve device 5 on the guide rail, the drill sleeve device 5 is driven by a linear motor (not shown in the figure) to move controllably on the guide rail.

[0047] like Figure 1 and Figure 2 As shown, to facilitate the transfer of the drill sleeve device 5 to the node plate hole group window 121 to adapt to different system line angles, a positioning guide rail 7 is provided in the node plate hole group window 121, and an adjustment device 6 is provided on the node plate template 12. This adjustment device 6 is used to move and adjust the drill sleeve device 5 between the first fine-tuning guide rail 3 and the positioning guide rail 7, between the two positioning guide rails 7, and between the second fine-tuning guide rail 4 and the positioning guide rail 7. To better understand the working principle of the drill sleeve device 5's movement and adjustment, the following describes... Figure 1 , Figure 2Taking the example shown, the movement and adjustment process of the drill sleeve device 5 is illustrated. In the initial state, the drill sleeve device 5 is located at the left end of the first fine-tuning guide rail 3. When drilling is required for the positioning holes on the vertical plate of the bridge slab, the drill sleeve device 5 is precisely controlled by a linear motor on the first fine-tuning guide rail 3, moving it to the vertical plate hole group window 111 corresponding to the area where the positioning holes need to be drilled on the vertical plate of the bridge slab. Then, the positioned drill sleeve device 5 drills the vertical plate positioning holes at this location, thus completing the drilling of the positioning holes on the vertical plate of the bridge slab. When drilling is required for the positioning holes on the node plate of the bridge slab, the adjusting device 6 rotates to... Figure 1 In the state shown, the adjusting device 6 and the end of the first fine-tuning guide rail 3 form a transition connection. The linear motor drives the drill sleeve device 5 to move from the first fine-tuning guide rail 3 to the adjusting device 6. Then, the adjusting device 6 continues to rotate, so that it forms a transition connection with the end of the positioning guide rail 7. Then, the linear motor drives the drill sleeve device 5 to move from the adjusting device 6 to the positioning guide rail 7, so that it moves to the node plate hole group window 121 corresponding to the area where the node plate of the bridge slab needs to be drilled with positioning holes. Then, the positioning holes of the node plate are drilled at this location by the positioned drill sleeve device 5, thereby completing the drilling of the positioning hole group at the node plate position of the bridge slab.

[0048] Furthermore, in a preferred embodiment of the present invention, the frame 2 is a frame structure made of lightweight material. As a preferred implementation, the frame 2 is made of lightweight material such as nylon or aluminum alloy. The lightweight frame 2 provides skeletal support for the template 1 while also reducing the weight of the entire template device, facilitating its movement. Specifically, as... Figure 6 As shown, the frame 2 includes a vertical plate frame 21 corresponding to the vertical plate template 11 and a node plate frame 22 corresponding to the node plate template 12. To provide more stable support for the node plate template 12, the node plate frame 22 has a horizontally extending frame 221 along the line connecting the two ends of the corresponding arc-shaped channel 122. The node plate frame 22 also has a fixing plate 222 connected to the horizontal frame 221 at the center of the corresponding node plate hole group window 121. Figure 6As shown, the horizontal frame 221 has first breaks 2211 at both ends of the arc-shaped channel 122 for the adjustment device 6 to pass through, and the fixing plate 222 has second breaks 2221 at the corresponding positions of the arc-shaped channel 122 for the adjustment device 6 to pass through. Through the first breaks 2211 and the second breaks 2221, the drill sleeve device 5 can be flexibly moved and adjusted between the first fine-tuning guide rail 3 and the positioning guide rail 7, between the two positioning guide rails 7, and between the second fine-tuning guide rail and the positioning guide rail 7. Due to the presence of the first breaks 2211, the middle main body of the horizontal frame 221 is separated from the overall frame and suspended. Therefore, in order to fix the suspended middle main body of the horizontal frame 221 in the corresponding position, the node plate template 12 area of ​​the template 1 has a matching mounting groove at the corresponding position of the suspended middle main body of the horizontal frame 221. Specifically, as shown... Figure 13 and Figure 14 As shown, Figure 13 This is a plan view of the first fine-tuning guide rail frame 3, the adjusting device 6, the positioning guide rail frame 7, and the second fine-tuning guide rail frame 4. Figure 14 This is a perspective view of the first fine-tuning guide rail frame 3, the adjustment device 6, the positioning guide rail frame 7, and the second fine-tuning guide rail frame 4. Under its self-propelled control and the guidance and adjustment of the adjustment device 6, the drill sleeve device 5 can move back and forth between the first fine-tuning guide rail frame 3, the adjustment device 6, the positioning guide rail frame 7, and the second fine-tuning guide rail frame 4.

[0049] Among them, as a preferred embodiment of the present invention, such as Figure 1 and Figure 3 As shown, template 1 consists of two pieces, with frame 2 fixedly positioned between the two templates 1. In some other embodiments of the invention, template 1 comprises only one piece, facing the bridge deck side, with frame 2 fixedly connected to template 1, and frame 2 located on the side away from the bridge deck (i.e., the back side of template 1). The template assembly is constructed from template 1 and lightweight frame 2, which can reduce the overall weight of the template device. In some other embodiments, such as... Figure 7 As shown, the skeleton 2 is a single structure in its cross-sectional direction. As a preferred embodiment of the present invention, as... Figure 8 As shown, the skeleton 2 is formed by combining and fixing two halved skeleton structures 2A in its cross-sectional direction. By combining and fixing these two halved skeleton structures 2A, the mold development cost during production can be reduced, and the production and molding of the skeleton 2 can be facilitated. Figure 4 Unlike the integrated structural template shown in one embodiment, in some other embodiments, to facilitate the assembly of template 1, such as... Figure 5 As shown, template 1 can also be a structure composed of multiple small panels, which is a spliced ​​template.

[0050] Furthermore, in a preferred embodiment of the present invention, such as Figure 6 As shown, the frame 2 has multiple electromagnet mounting holes 23, and electromagnets 8 for magnetically fixing the bridge plate are installed in the electromagnet mounting holes 23. The template 1 has adapter holes 112 at the positions corresponding to the electromagnet mounting holes 23. Figure 1 As shown, the magnetic end of electromagnet 8 is located on the side facing the bridge plate. When drilling the positioning hole, electromagnet 8 is magnetically fixed to the bridge plate, so that the template device and the bridge plate are positioned, avoiding relative displacement between the template 1 and the bridge plate when drilling the positioning hole, thus preventing drilling deviation.

[0051] Furthermore, in a preferred embodiment of the present invention, such as Figure 9 and Figure 10 As shown, the drill sleeve device 5 includes two horizontally arranged vertically with adjustable spacing, and two vertically arranged horizontally with adjustable spacing, and two vertically arranged horizontally with adjustable spacing. Each of the horizontal and vertical sliding positioning plates 51 and 52 has an elongated adjustment hole 53 at its end. The adjustment holes 53 of the horizontal and vertical sliding positioning plates 51 and 52 form a cross, and a sliding and adjustable clamp 54 is engaged at the intersection. The drill sleeve 55 is fixedly engaged in the clamp 54. Specifically, when a horizontal adjustment hole 53 and a vertical adjustment hole 53 form a cross, a square locking hole is formed at the intersection. The drill sleeve 55 is engaged in this square locking hole, and the sliding positioning plate can move the drill sleeve 55 within the locking hole during sliding. Figure 9 As shown, two horizontal sliding positioning plates 51 and two vertical sliding positioning plates 52 intersect to form a cross, creating four cross-shaped holes for mounting the clamps 54. These four cross-shaped holes are connected sequentially to form a rectangle. By adjusting the relative vertical spacing of the two horizontal sliding positioning plates 51, the distance between the two upward-moving clamps 54 and the two downward-moving clamps 54 can be adjusted accordingly. Similarly, by adjusting the relative horizontal spacing of the two vertical sliding positioning plates 52, the distance between the two clamps 54 in the left column and the two clamps 54 in the right column can be adjusted accordingly. This allows for adjustment of the hole spacing between the four drill bushings 55, accommodating drilling of different types of sheet metal.

[0052] Furthermore, in a preferred embodiment of the present invention, such as Figure 9 and Figure 10As shown, a horizontal forward and reverse spiral screw assembly 57, whose relative spacing is adjustable, is connected between two vertical sliding positioning plates 52, and a vertical forward and reverse spiral screw assembly 58, whose relative spacing is adjustable, is connected between two horizontal sliding positioning plates 51. The horizontal forward and reverse spiral screw assembly 57 and the vertical forward and reverse spiral screw assembly 58 are fixed in a cross shape. The spiral screws at both ends of the horizontal forward and reverse spiral screw assembly 57 synchronously drive the vertical sliding positioning plates 52 connected to it, controlling the relative spacing of the two vertically arranged left-right vertical sliding positioning plates 52. The spiral screws at both ends of the vertical forward and reverse spiral screw assembly 58 synchronously drive the horizontal sliding positioning plates 51 connected to it, controlling the relative spacing of the two horizontally arranged up-down horizontal sliding positioning plates 51. Figure 10 As shown, the base of the horizontal positive and negative spiral screw assembly 57 is slidably connected to the guide rail of the first fine-tuning guide rail frame 3 via a slider 59. A linear motor (not shown) on the drill sleeve device 5 drives it to move controllably along the guide rail. When the drill sleeve device 5 adjusts its position, the slider 59 can transition to the guide rails of the adjusting device 6, the positioning guide rail frame 7, and the second fine-tuning guide rail frame 4, allowing the drill sleeve device 5 to move to different drilling positions. That is, the slider 59 can be selectively slidably connected to the guide rails of the first fine-tuning guide rail frame 3, the adjusting device 6, the positioning guide rail frame 7, and the second fine-tuning guide rail frame 4 on the side facing the bridge slab. In an embodiment of the invention, the horizontal positive and negative spiral screw assembly 57 and the vertical positive and negative spiral screw assembly 58 are respectively connected to screw motors (not shown). Each screw motor drives the two ends of its spiral screw to rotate in opposite directions, thereby controlling the sliding positioning plates at both ends to move relatively closer or further apart.

[0053] Furthermore, in a preferred embodiment of the present invention, such as Figure 11 and Figure 12 As shown, the clamp 54 has distance sensors 56 on its outer periphery in four directions (up, down, left, and right) for positioning the distance between adjacent drill sleeves. Through the sensing of the distance sensors 56, the distance between drill sleeves can be precisely controlled, achieving precise positioning between them. Figure 12 As shown, the fixture 54 is also provided with a jaw 541 for clamping the drill bushing 55. A drill bushing of appropriate size can be selected according to the size of the positioning hole to be drilled.

[0054] Furthermore, in a preferred embodiment of the present invention, such as Figure 15As shown, the adjustment device 6 includes an angle fine-tuning mechanism 61 fixed to the node plate template 12 on the side facing away from the bridge plate, a servo motor driven by the torque input end of the angle fine-tuning mechanism 61, a drive shaft 62 driven by the torque output end of the angle fine-tuning mechanism 61 and passing through the template assembly, and at least one adjustment guide rail 63 connected to the end of the drive shaft 62 on the side facing the bridge plate. The end of the adjustment guide rail 63 is provided with a locking and positioning mechanism that engages with the guide rail docking ends of the first fine-tuning guide rail frame 3, the positioning guide rail frame 7, and the second fine-tuning guide rail frame 4. When it is necessary to move the position of the drill sleeve device 5, the docking and fixing of the transition joint between the guide rails is first completed, and then the drill sleeve device 5 is moved to the corresponding guide rail under the self-propelled control. Specifically, as... Figure 12 As shown, when the drill sleeve device 5 needs to be transferred from the first fine-tuning guide rail frame 3 to the adjusting device 6, the adjusting device 6 adjusts its swing angle to a horizontal state, aligning its end with the guide rail mating end of the first fine-tuning guide rail frame 3 in a straight line. Then, under the travel control of its linear motor, the drill sleeve device 5 transitions from the guide rail on the first fine-tuning guide rail frame 3 to the guide rail on the adjusting device 6, thus realizing the transfer of the drill sleeve device 5 between the first fine-tuning guide rail frame 3 and the adjusting device 6. After the drill sleeve device 5 is completely transferred to the guide rail of the adjusting device 6, the adjusting device 6 continues to rotate an angle, aligning its end with the guide rail mating end of the positioning guide rail frame 7 in a straight line. Then, under the travel control of its linear motor, the drill sleeve device 5 transitions from the guide rail on the adjusting device 6 to the guide rail on the positioning guide rail frame 7, thus realizing the transfer of the drill sleeve device 5 between the adjusting device 6 and the positioning guide rail frame 7. After the drill sleeve device 5 is completely transferred to the guide rail of the positioning guide rail frame 7, the drilling of the node plate positioning hole group can be performed at that location. Similarly, the transfer of the drill sleeve device 5 between the two positioning guide rails 7, and the transfer of the drill sleeve device 5 between the positioning guide rails 7 and the second fine-tuning guide rail 4, are based on the same transfer principle as described above, and will not be repeated here.

[0055] Furthermore, in a preferred embodiment of the present invention, such as Figure 19 As shown, the positioning guide rail frame 7 includes at least one positioning guide rail 71 fixed to the side of the node plate template 12 facing the bridge slab. The positioning guide rail 71 coincides with the center line of the node plate hole group window 121 in its orthographic projection, wherein the lower end of the center line extends in a direction that coincides with the rotation axis of the adjustment device 6. Figure 17 The diagram shows the structure of the positioning guide rail 7 on the overall template device. A positioning guide rail 7 is installed in each of the two node plate hole groups 121 at different angles. Specifically, as shown... Figure 18 As shown, to enhance the stability of the positioning guide rail 71, the positioning guide rail 71 is fixed to the side edge of the fixing plate 222 facing the bridge plate. Figure 22As shown, the first fine-tuning guide rail 3 includes at least one horizontally extending first fine-tuning guide rail 31 located on the front of the template assembly, and the second fine-tuning guide rail 4 includes at least one horizontally extending second fine-tuning guide rail 41 located on the front of the template assembly.

[0056] In some embodiments of the present invention, such as Figure 14 and Figure 19 As shown, the first fine-tuning guide rail frame 3 includes two horizontally extending and parallel first fine-tuning guide rails 31 arranged on the front and back of the template assembly, one of which is located on the side facing the bridge plate and the other on the side facing away from the bridge plate. The second fine-tuning guide rail frame 4 includes two horizontally extending and parallel second fine-tuning guide rails 41 arranged on the front and back of the template assembly, one of which is located on the side facing the bridge plate and the other on the side facing away from the bridge plate. The positioning guide rail frame 7 includes two positioning guide rails 71, one of which is located on the side facing the bridge plate and the other on the side facing away from the bridge plate. The adjusting device 6 has two adjusting guide rails 63, which are respectively connected to the two ends of the drive shaft 62, one of which is located on the side facing the bridge plate and the other on the side facing away from the bridge plate.

[0057] In some embodiments of the present invention, such as Figure 22 As shown, the first fine-tuning guide rail frame 3, the second fine-tuning guide rail frame 4, the adjustment device 6, and the positioning guide rail frame 7 are all single-sided guide rails, and the single-sided guide rails are all arranged on the side facing the bridge deck.

[0058] Furthermore, in a preferred embodiment of the present invention, such as Figure 14 , Figure 15 , Figure 18 as well as Figure 19 As shown, the docking and positioning mechanism includes a first magnetic fixing frame 32 connected to the docking end of the first fine-tuning guide rail 31, a second magnetic fixing frame 42 connected to the docking end of the second fine-tuning guide rail 41, a third magnetic fixing frame 72 connected to the docking end of the positioning guide rail 71, and a fourth magnetic fixing frame 64 connected to the end of the adjusting guide rail 63. The outer end faces of the first magnetic fixing frame 32, the second magnetic fixing frame 42, the third magnetic fixing frame 72, and the fourth magnetic fixing frame 64 are all provided with electromagnetic suction blocks 10. Figure 14 As shown, when the adjusting guide rail 63 is transitionally connected to the first fine-tuning guide rail 31, the fourth magnetic fixing bracket 64 is opposite to the first magnetic fixing bracket 32. At this time, the electromagnetic blocks 10 on the fourth magnetic fixing bracket 64 and the first magnetic fixing bracket 32 ​​are energized and attracted together, which plays a stabilizing and strengthening role in the connection between the adjusting guide rail 63 and the first fine-tuning guide rail 31.

[0059] To achieve accurate alignment between the guide rails, a precise alignment mechanism is provided between the guide rail mating end of the first fine-tuning guide rail 31, the guide rail mating end of the second fine-tuning guide rail 41, and the guide rail mating end of the positioning guide rail 71 and the end of the adjusting guide rail 63, respectively. This precise alignment mechanism allows the first fine-tuning guide rail frame 3, the second fine-tuning guide rail frame 4, and the positioning guide rail frame 7 to achieve rapid and precise alignment with the adjusting device 6, thereby completing the rapid connection and transition between the guide rails. Specifically, in a preferred embodiment of the present invention, as shown... Figure 16 and Figure 19 As shown, the precise alignment mechanism includes a ball groove 631 at the end of the adjusting guide rail 63, a spring 632 disposed in the ball groove 631, and a spring-limiting ball 633 movably disposed at the opening of the ball groove 631. The spring-limiting ball 633 is fixedly connected to the spring 632, and has a protruding portion of less than half its length at the opening of the ball groove 631. When the spring-limiting ball 633 is not under force, the spring 632 is in a free state. To facilitate understanding of this precise alignment mechanism, the following explanation uses the positioning guide rail 71 as an example. Figure 19 Taking the example shown, the guide rail 71 has a semi-circular ball groove 20 at its guide rail docking end, which is adapted to the protruding part of the spring limiting ball 633. When the adjustment guide rail 63 rotates and docks with the positioning guide rail 71, the spring limiting ball 633 at the end of the adjustment guide rail 63 contacts the guide rail docking end of the positioning guide rail 71. Under the squeezing action, the spring 632 is compressed, and the spring limiting ball 633 retracts into the ball groove 631. After the ball groove 631 and the semi-circular ball groove 20 are completely aligned, the spring 632 recovers its elastic deformation, and the spring limiting ball 633 pops out part of the ball again, with the protruding part of the ball fitting into the semi-circular ball groove 20, thus quickly completing the alignment of the adjustment guide rail 63 and the positioning guide rail 71. After the alignment is completed, the electromagnetic blocks 10 on the third magnetic fixing bracket 72 and the fourth magnetic fixing bracket 64 are energized, completing the stable connection between the positioning guide rail 71 and the adjustment guide rail 63. Similarly, semi-circular ball grooves 20 are respectively provided at the ends of the guide rail docking end of the first fine-tuning guide rail 31, the guide rail docking end of the second fine-tuning guide rail 41, and the guide rail docking end of the positioning guide rail 71.

[0060] Furthermore, in a preferred embodiment of the present invention, such as Figure 1 As shown, clamping plates 9 are respectively provided at both ends of the frame 2. The clamping plates 9 at both ends can be moved closer or further apart. By adjusting the clamping plates 9, the present invention can be adapted to bridge panels of different lengths. At the same time, the clamping plates 9 also have a workpiece positioning function. The clamping plates 9 on both sides can be extended and retracted synchronously on both sides. Combined with the self-adaptive characteristics of the movable template assembly, the center of the clamping plate 9 can be made to coincide with the center of the bridge panel. Specifically, see Figure 20 and Figure 21As shown, the clamping plate 9 has a guide post 911 extending along the length of the template 1 and a telescopic electric cylinder 92 arranged parallel to the guide post 911 at one end facing the back of the template 1. See also Figure 7 As shown, the end of the frame 2 has a guide post mounting port 26 and an electric cylinder mounting port 27. The guide post 911 is slidably fitted into the guide post mounting port 26, and the telescopic electric cylinder 92 is fixedly installed in the electric cylinder mounting port 27. When it is necessary to adjust the distance between the clamping plates 9, the telescopic electric cylinder 92 is activated, which can drive the guide post 911 of the clamping plate 9 to slide in the guide post mounting port 26 at the end of the frame 2, thereby realizing the clamping adjustment between the two opposing clamping plates 9.

[0061] Furthermore, to facilitate the movement of the overall template device of the present invention, the bottom of the frame 2 is provided with multiple roller grooves 24 along its length, and universal wheels 25 are provided in the roller grooves 24. To facilitate installation and accommodate drilling positions where the system line angle changes after arching, such as... Figure 4 and Figure 18 As shown, the surface of template 1 has grooves 113 at each guide rail corresponding to the first fine-tuning guide rail frame 3 and the second fine-tuning guide rail frame 4. The side edge of the fixing plate 222 facing the bridge deck also has grooves 113, and each groove 113 contains a fine-tuning fixing mechanism. These fine-tuning fixing mechanisms provide installation stability for the first fine-tuning guide rail frame 3, the second fine-tuning guide rail frame 4, and the positioning guide rail frame 7. Furthermore, under stress, some positions on the bridge deck may arch, causing changes in the system line angle, which in turn affects the drilling angle. The following section will illustrate this further. Figure 2 and Figure 24 The following example illustrates the concept. If the corresponding... Figure 2 The bridge slab on the left side of the vertical template 11 shown has arched, which will cause the drilling positions on the bridge slab to change angle. For ease of understanding, the following example... Figure 24 The two states shown are explained below. In Figures (a) and (b), the small circles at the four corners represent drilling positions. The two vertical columns and two horizontal rows of lines represent the vertical sliding positioning plate 52 and the horizontal sliding positioning plate 51, respectively. Figure (a) shows the angular relationship of the four drilling positions in the bridge deck when it is not arched, while Figure (b) shows the angular relationship of the four drilling positions in the bridge deck when it is arched. From the change in the angle of the drilling positions in Figures (a) and (b), it can be seen that during arching, simply relying on the adjustment of the horizontal positive and negative spiral screw assembly 57 and the vertical positive and negative spiral screw assembly 58 is not enough to drill positioning holes for drilling positions with angles. At this time, it is also necessary to use... Figure 2 The fine-tuning fixing mechanism in the row of grooves 113 arranged in a straight line on the left side of the vertical plate template 11, as shown, assists in completing the first fine-tuning guide rail 3. Figure 2The left side of the vertical template 11 shown is slightly angled to accommodate the angled drill holes on the bridge deck.

[0062] Specifically, the adjusting device 6 is fixed to the first fine-tuning guide rail 3, and then, under the rotation adjustment of the adjusting device 6, the first fine-tuning guide rail 3 and the adjusting device 6 rotate synchronously by a corresponding fine-tuning swing angle, so that the first fine-tuning guide rail 3... Figure 2 The left side of the vertical template 11 shown is tilted at the same angle as the swing angle of the adjusting device 6. Similarly, Figure 2 The system line angle adjustment in the right area of ​​the vertical template 11 shown is assisted by the fine-tuning fixing mechanism in the groove position 113 distributed in a straight line in that area, which helps the second fine-tuning guide rail 4 to complete the small angle adjustment. The system line angle adjustment of the positioning guide rail 7 on the node plate template 12 is assisted by the fine-tuning fixing mechanism in the groove position 113 on the side edge of the fixing plate 222 facing the bridge plate to complete the small angle adjustment.

[0063] In one preferred embodiment of the present invention, such as Figure 14 , Figure 18 , Figure 19 as well as Figure 23 As shown, the fine-tuning fixing mechanism in the groove 113 includes an arc-shaped slide rail 114 with an arcuate curvature and a slider 115 slidably connected to the arc-shaped slide rail 114. Each guide rail of the first fine-tuning guide rail frame 3, the second fine-tuning guide rail frame 4, and the positioning guide rail frame 7 is fixedly connected to the slider 115 in the corresponding position of the fine-tuning fixing mechanism. Figure 13 As shown in the example, since the first fine-tuning guide rail 3 rotates synchronously with the adjusting device 6 by a corresponding fine-tuning swing angle, and the first fine-tuning guide rail 3 has a relatively large swing amplitude at the end far from the rotation center of the adjusting device 6, the arc length of the arc-shaped slide rail 114 in each fine-tuning fixing mechanism corresponding to the first fine-tuning guide rail 3 is different. Specifically, along the rotation center of the adjusting device 6 towards the far end of the first fine-tuning guide rail 3 ( Figure 13 (At the left end), the arc length of the arc-shaped slide rail 114 in each fine-tuning fixing mechanism gradually increases, and they have the same radius of curvature. The change in system line angle caused by camber is small (although small, it still requires adjustment of the drill sleeve device 5). Figure 24 (Adaptive adjustment of angles from Figure (a) to Figure (b)). Therefore, the fine-tuning swing angles of the first fine-tuning guide rail 3, the second fine-tuning guide rail 4, and the positioning guide rail 7 are also smaller, and the resulting swing amplitude is also smaller. Therefore, the radius of curvature of the arc-shaped slide rail 114 is larger. Figure 23 The diagram shows an approximate straight track.

[0064] The usage process of the overall template device of the present invention is as follows:

[0065] Step 1: Use the hoisting device to hoist the entire template device to the position of the bridge deck, so that the casters 25 contact the plane where the lower edge of the bridge deck is located. Then use the hoisting device to move the entire template device so that it is attached to the bridge deck.

[0066] Step 2: Clamp the two ends of the bridge plate with the clamping plates 9, and fix the electromagnet 8 to the bridge plate by electromagnetic attraction, so that the template 1 and the bridge plate are positioned.

[0067] Step 3: Drive the linear motor on the drill sleeve device 5 to move on the first fine-tuning guide rail 31 on the first fine-tuning guide rail frame 3. When it moves to the window 111 of the vertical plate hole group to be drilled, fix the drill sleeve device 5 at this position, adjust the hole spacing of the drill sleeve device 5, and then perform precise drilling of the vertical plate positioning hole through the drill sleeve device 5.

[0068] Step 4: When drilling the node plate positioning holes, start the servo motor of the adjustment device 6 to drive the adjustment guide rail 63 to rotate, so that the adjustment guide rail 63 and the first fine-tuning guide rail 31 of the first fine-tuning guide rail frame 3 are connected. Then, the drill sleeve device 5 is transferred from the first fine-tuning guide rail 31 to the adjustment guide rail 63. Continue to drive the adjustment guide rail 63 to rotate to the specified angle and stop, so that it is aligned and connected with the positioning guide rail frame 7 on the node plate hole group window 121. Then, the drill sleeve device 5 is transferred from the adjustment guide rail 63 to the positioning guide rail 71. After adjusting and fixing the position and hole spacing of the drill sleeve device 5, the node plate positioning holes are precisely drilled through the drill sleeve device 5.

[0069] It should be noted that in the embodiments of the present invention, the position of the groove 113 is related to the position of the hole group on the template 1, and is not isolated. That is, if the position of the hole group on the template 1 changes, the groove 113 must also be adapted accordingly. For example, as shown... Figure 25 As shown, the positions of the grooves 113 on the template 1 vary depending on the location of the hole groups (dashed boxes in the figure). Generally, the grooves 113 are arranged along the path of the drill sleeve device 5. However, the path of the drill sleeve device 5 differs for different hole groups. Specifically, in... Figure 25 In Figure (a), the positional relationship between the groove position 113 and the hole group is shown as a horizontal straight line in one embodiment, and in Figure (b), the positional relationship between the groove position 113 and the hole group is shown as an oblique straight line in another embodiment.
