Description

Technical Field

[0001] The present invention relates to the technical field of drilling holes in bridge plates of large rods of steel structure bridges, and in particular to an adjustable template, which is an overall template device for drilling positioning holes of super-large rods that can meet the requirements of positioning hole processing of bridge plates of different specifications. Background Art

[0002] In steel structure bridges, steel beams are mainly composed of upper and lower chords of the main truss, web members, transverse and longitudinal beams, bridge decks, upper chords of secondary trusses, diagonal braces of secondary trusses, etc. Except for orthogonal anisotropic steel bridge decks, truss members adopt box-shaped and I-shaped sections. Steel truss members and transverse and longitudinal beam members are manufactured in the workshop according to the basic procedures of "cutting → processing → assembly → welding → correction → hole punching". After passing the inspection, they are assembled in a plane. After passing the test assembly inspection, they are disassembled into single pieces, surface treated, painted, and shipped to the bridge site in bulk, and assembled and installed on the bridge. A typical upper chord consists of an integral node plate, a vertical plate, a top plate, a bottom plate, a partition, a bridge deck cross beam joint plate, a web member joint plate, etc. The maximum weight of a single member is about 50 tons, and the 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 plate and the node plate. The lower chord is mainly composed of upper and lower horizontal plates, vertical plates, node plates, partitions, rib plates, secondary truss diagonal brace joint plates, and beam joint plates. The maximum weight of a single member is about 67 tons, and it is installed horizontally. In the manufacturing process of the lower chord, it is necessary to solve the drilling problem of the lower chord vertical plate and node plate.

[0003] At present, some workshops have double gantry CNC machine tools that can pass rods with a height of 5000mm and a width of 2500mm. They can simultaneously drill three holes on one end of the rod, ensuring that the bolt holes on different planes are not misaligned in the longitudinal and transverse directions, and can drill bolt holes at both ends and node positions of the cross-section rods. However, some frame gantry CNC machine tools can only pass rods with a height of 1950mm and a width of 2500mm, and cannot meet the problem of passing rods with a height greater than 2000mm through the gantry CNC machine tools and drilling bolt holes at both ends and node positions at the same time. For rods that cannot pass through the gantry CNC, the drilling method of manually marking and drilling positioning holes with a small sample plate or making a large covering sample plate to drill positioning holes with a small sample plate is usually used. The drilling method of manually marking three-dimensional holes, drilling positioning holes, and then drilling with a small sample plate is difficult to mark. Due to the limited technical level of the operator, it is easy to cause the error of the same surface group of the rod to exceed the standard. Therefore, it is generally adopted to make a large covering sample plate to drill positioning holes and then drill with a small sample plate to ensure the relative accuracy of the rod hole group. At present, when encountering projects where extra-large rods need to be drilled, large covering samples are basically made for specific projects.

[0004] Now, with the development and innovation of steel truss bridges in my country, most of the main beams of truss bridges have different shapes and sizes. According to the limitations of manufacturing and transportation capacity, even if the sizes of some steel truss main beams are roughly the same, the different stress conditions lead to different arches of the rods, and the rod system lines of the same project are different. In some projects, because the entire truss adopts the method of extending the upper chord rod, shortening the lower chord rod, and keeping the length of the vertical rod unchanged, the entire bridge line is arched and set out by changing the angle of the system line, which leads to different angles of the system lines of the upper and lower chord rods, which brings a huge workload to the production of large-scale covering templates. The angles of 41 different system lines of the two main trusses, if you want to make a pair of integrated templates, then the hole group will be very dense, and the system lines at both ends of the template will also be very dense, which will require extremely high selection of holes and production of templates by the workshop drilling workers, and the probability of drilling the wrong holes will also be greatly increased. Summary of the invention

[0005] In order to solve the problem of drilling multi-angle system lines and hole group positioning holes with different hole group positions, the present invention provides an overall template device for drilling positioning holes for super-large rods.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0046] See also 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 of super-large rods, the template device includes a movable template assembly, the template assembly is composed of a template 1 and a skeleton 2, the template 1 is a bridge plate profiling plate to be drilled with positioning holes, and the skeleton 2 is a supporting structure that provides structural support for the template 1. Figure 1 , Figure 2 and Figure 4 As shown, the template 1 includes a vertical plate template 11 and a node plate template 12. The vertical plate template 11 is provided with a plurality of vertical plate hole group windows 111 along its length direction, and the node plate template 12 is provided with at least two node plate hole group windows 121 located at different angles. According to the system line angle of the upper and lower chords, the positioning holes can be drilled at the node plate hole group windows 121 at the corresponding angles. Figure 4 As shown, the node plate template 12 is provided with an arc-shaped passage 122 connected to the lower side of the node plate hole group window 121. The arc-shaped passage 122 is an arc-shaped through opening that runs through the front side (the side facing the bridge plate) and the back side (the side facing away from the bridge plate) of the template component. Figure 4 As shown, the arc channel 122 is semicircular, and the arch direction is set upward. Figure 1 , Figure 2 As shown, the vertical plate template 11 is provided with a first fine-tuning guide frame 3 and a second fine-tuning guide frame 4 located at the left and right ends of the arc channel 122 in its length direction, wherein the first fine-tuning guide frame 3 is connected to the corresponding end of the arc channel 122 at the end close to the node plate template 12, and the second fine-tuning guide frame 4 is connected to the corresponding end of the arc channel 122 at the end close to the node plate template 12. Figure 1 and Figure 2 As shown, the first fine-tuning guide rail frame 3 is provided with a movable drill sleeve device 5 on the guide rail on the side facing the bridge plate, and the position where the hole needs to be drilled is positioned by the drill sleeve device 5 to facilitate the drill bit to drill accurately. In order to facilitate the automatic walking 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, in order 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 frame 7 is provided in the node plate hole group window 121, and an adjustment device 6 is provided on the node plate template 12. The adjustment device 6 is used to move and adjust the drill sleeve device 5 between the first fine-tuning guide frame 3 and the positioning guide frame 7, between the two positioning guide frames 7, and between the second fine-tuning guide frame 4 and the positioning guide frame 7. In order to facilitate a better understanding of the working principle of the movement and adjustment of the drill sleeve device 5, the following is a detailed description of the movement and adjustment of the drill sleeve device 5. Figure 1 , Figure 2Taking the figure as an example, the movement and adjustment process of the drill sleeve device 5 is exemplified. In the initial state, the drill sleeve device 5 is located at the left end of the first fine-tuning guide frame 3. When it is necessary to drill the positioning hole group on the vertical plate position of the bridge plate, the drill sleeve device 5 is driven by a linear motor on the first fine-tuning guide frame 3 to accurately control the displacement, so that it moves 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 plate. Then, the vertical plate positioning holes are drilled at this location by the positioned drill sleeve device 5, thereby completing the drilling of the positioning hole group on the vertical plate position of the bridge plate. When it is necessary to drill the positioning hole group on the node plate position of the bridge plate, the adjustment device 6 is rotated to Figure 1 The state shown, at this time, the adjusting device 6 forms a transition connection with the end of the first fine-tuning guide frame 3, and the linear motor drives the drill sleeve device 5 to move from the first fine-tuning guide frame 3 to the adjusting device 6 by itself, and then the adjusting device 6 continues to rotate, so that it forms a transition connection with the end of the positioning guide frame 7, and then the linear motor drives the drill sleeve device 5 to move from the adjusting device 6 to the positioning guide frame 7 by itself, so that it moves to the node plate hole group window 121 corresponding to the area where the node plate of the bridge plate needs to drill the positioning hole, and then, the node plate positioning hole is drilled at this location through the positioned drill sleeve device 5, thereby completing the drilling of the positioning hole group at the node plate position of the bridge plate.

[0048] Furthermore, in a preferred embodiment of the present invention, the frame 2 is a frame-type structure of a lightweight material. As a preferred embodiment, the frame 2 is made of a lightweight material such as nylon or aluminum alloy. The lightweight frame 2 not only provides a skeleton support for the template 1, but also reduces the weight of the entire template device, making it easier to move. Specifically, Figure 6 As shown, the frame 2 includes a vertical frame 21 corresponding to the vertical plate template 11 and a node plate frame 22 corresponding to the node plate template 12, wherein, in order to provide more stable support for the node plate template 12, the node plate frame 22 is provided with a horizontal frame 221 extending horizontally and straightly on the connecting line of the two ends of the corresponding arc-shaped channel 122, and the node plate frame 22 is provided with a fixing plate 222 connected to the horizontal frame 221 at the middle position of the corresponding node plate hole group window 121. Figure 6As shown, the horizontal frame 221 is provided with a first break 2211 for the adjustment device 6 to pass through at both ends of the arc-shaped channel 122, and the fixed plate 222 is provided with a second break 2221 for the adjustment device 6 to pass through at a position corresponding to the arc-shaped channel 122. Through the first break 2211 and the second break 2221, the drill sleeve device 5 can be flexibly moved and adjusted between the first fine-tuning guide frame 3 and the positioning guide frame 7, between the two positioning guide frames 7, and between the second fine-tuning guide frame and the positioning guide frame 7. Due to the existence of the first break 2211, the middle main body part of the horizontal frame 221 is separated from the entire skeleton and suspended. Therefore, in order to fix the suspended middle main body part of the horizontal frame 221 at a corresponding position, the node plate template 12 area of ​​the template 1 is provided with a mounting groove adapted thereto at a position corresponding to the suspended middle main body part of the horizontal frame 221. Specifically, as Fig.13 and Fig.14 As shown, Fig.13 It 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, Fig.14 It is a three-dimensional diagram of the first fine-tuning guide frame 3, the adjusting device 6, the positioning guide frame 7 and the second fine-tuning guide frame 4. The drill sleeve device 5 can be moved back and forth and adjusted between the first fine-tuning guide frame 3, the adjusting device 6, the positioning guide frame 7 and the second fine-tuning guide frame 4 under its self-propelled control and the guidance and adjustment of the adjusting device 6.

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

[0050] Further, in a preferred embodiment of the present invention, Figure 6 As shown, the frame 2 is provided with a plurality of electromagnet mounting holes 23, in which electromagnets 8 for magnetically fixing the bridge plate are provided, and the template 1 is provided with an adapter hole 112 at a position corresponding to the electromagnet mounting hole 23. Figure 1 As shown, the magnetic end of the electromagnet 8 is located on the side facing the bridge plate. When drilling the positioning hole, the 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, so as to prevent drilling deviation.

[0051] Further, in a preferred embodiment of the present invention, Fig. 9 and Fig.10 As shown, the drill sleeve device 5 includes two horizontal sliding positioning plates 51 which are arranged horizontally up and down and have adjustable spacing, and two vertical sliding positioning plates 52 which are arranged vertically left and right and have adjustable spacing. Among them, the ends of the horizontal sliding positioning plates 51 and the vertical sliding positioning plates 52 are both provided with long strip-shaped adjustment holes 53, and the adjustment holes 53 of the horizontal sliding positioning plates 51 and the vertical sliding positioning plates 52 form a cross, and a clamp 54 with sliding adjustable displacement is clamped at the intersection, and a drill sleeve 55 is clamped and fixed in the clamp 54. Specifically, when a horizontal adjustment hole 53 and a vertical adjustment hole 53 form a cross, a square clamping hole is formed at the cross, and the drill sleeve 55 is clamped in the square clamping hole. When sliding, the sliding positioning plate can drive the drill sleeve 55 to slide in the clamping hole. As shown Fig. 9 As shown, two horizontal sliding positioning plates 51 and two vertical sliding positioning plates 52 are crossed to form a cross, forming a total of four cross-shaped holes for installing the clamps 54, and the four cross-shaped holes are connected in sequence to form a rectangle. The two horizontal sliding positioning plates 51 can adjust the relative spacing up and down to change the distance between the two clamps 54 in the upper row and the two clamps 54 in the lower row, and the two vertical sliding positioning plates 52 can adjust the relative spacing left and right to change the distance between the two clamps 54 in the left column and the two clamps 54 in the right column, thereby completing the hole spacing adjustment between the four drill sleeves 55, so as to adapt to the drilling of different types of plates.

[0052] Further, in a preferred embodiment of the present invention, Fig. 9 and Fig.10As shown, a horizontal forward and reverse spiral screw assembly 57 capable of adjusting the relative spacing between the two vertical sliding positioning plates 52 is connected, and a vertical forward and reverse spiral screw assembly 58 capable of adjusting the relative spacing between the two horizontal sliding positioning plates 51 is connected. The horizontal forward and reverse spiral screw assembly 57 and the vertical forward and reverse spiral screw assembly 58 are cross-fixed. The spiral screws at both ends of the horizontal forward and reverse spiral screw assembly 57 respectively synchronously drive the vertical sliding positioning plates 52 connected thereto, and control the two vertically arranged left and right vertical sliding positioning plates 52 to adjust their relative spacing. The spiral screws at both ends of the vertical forward and reverse spiral screw assembly 58 respectively synchronously drive the horizontal sliding positioning plates 51 connected thereto, and control the two horizontally arranged upper and lower horizontal sliding positioning plates 51 to adjust their relative spacing. As shown Fig.10 As shown, the base of the horizontal forward and reverse spiral screw assembly 57 is slidably connected to the guide rail of the first fine-tuning guide rail frame 3 through a slider 59, and the linear motor (not shown in the figure) on the drill sleeve device 5 drives it to move controllably on the guide rail. When the drill sleeve device 5 adjusts its position, the slider 59 can be transitionally connected to the guide rails of the adjustment device 6, the positioning guide rail frame 7 and the second fine-tuning guide rail frame 4, so that the drill sleeve device 5 is transferred to different hole-making positions. That is, the slider 59 can be selectively slidably connected to 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 on the side of the guide rail facing the bridge plate. In the embodiment of the present invention, the horizontal forward and reverse spiral screw assembly 57 and the vertical forward and reverse spiral screw assembly 58 are respectively connected to screw motors (not shown in the figure), and each screw motor drives the two ends of its spiral screw to rotate forward and backward respectively, thereby controlling the sliding positioning plates at both ends to achieve relative proximity or relative distance.

[0053] Further, in a preferred embodiment of the present invention, Fig.11 and Fig.12 As shown, the outer peripheral side of the fixture 54 is provided with distance sensors 56 for locating the distance between adjacent drill bushings at four positions, namely, up, down, left, and right. Through the sensing of the distance sensors 56, the distance between the drill bushings can be accurately controlled to achieve accurate positioning between the drill bushings. Fig.12 As shown, the clamp 54 is also provided with a clamping claw 541 for clamping the drill sleeve 55. A drill sleeve of a suitable size can be selected according to the size of the positioning hole to be drilled.

[0054] Further, in a preferred embodiment of the present invention, Fig.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 drivingly connected to the torque input end of the angle fine-tuning mechanism 61, a drive shaft 62 drivingly connected to the torque output end of the angle fine-tuning mechanism 61 and penetrating 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. Among them, a docking and positioning mechanism with a snap-fitting fit is provided between the end of the adjustment guide rail 63 and the first fine-tuning guide rail frame 3, the positioning guide rail frame 7, and the guide rail docking end of the second fine-tuning guide rail frame 4. When it is necessary to transfer 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 transferred to the corresponding guide rail under the self-propelled control. Specifically, as Fig.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, so that its end is aligned with the guide rail docking end of the first fine-tuning guide rail frame 3 on a straight line. Then, 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 under the running control of its linear motor, thereby 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, so that its end is aligned with the guide rail docking end of the positioning guide rail frame 7 on a straight line. Then, 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 under the running control of its linear motor, thereby 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 work of the node plate positioning hole group can be carried out there. Similarly, the transfer of the drill sleeve device 5 between the two positioning guide rail frames 7, and the transfer of the drill sleeve device 5 between the positioning guide rail frame 7 and the second fine-tuning guide rail frame 4 are the same as the above-mentioned transfer principles, which will not be repeated here.

[0055] Further, in a preferred embodiment of the present invention, Fig.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 plate, and the positioning guide rail 71 coincides with the center line of the node plate hole group window 121 in the positive projection, wherein the lower end extension direction of the center line coincides with the rotation axis of the adjustment device 6. Fig.17 As shown in FIG. 1 , it is a structural diagram of the positioning guide rail frame 7 on the overall template device, and a positioning guide rail frame 7 is respectively provided in two node plate hole group windows 121 at different angles. Specifically, as Fig.18 As shown, in order to enhance the stability of the positioning rail 71, the positioning rail 71 is fixed to the side edge of the fixing plate 222 facing the bridge plate. Fig. 22As shown, the first fine-tuning guide rail frame 3 includes at least one first fine-tuning guide rail 31 extending horizontally and arranged on the front side of the template assembly, and the second fine-tuning guide rail frame 4 includes at least one second fine-tuning guide rail 41 extending horizontally and arranged on the front side of the template assembly.

[0056] In some embodiments of the present invention, Fig.14 and Fig.19 As shown, the first fine-tuning guide rail frame 3 includes two first fine-tuning guide rails 31 extending horizontally and arranged in parallel on the front and back of the template assembly, one of which is set on the side facing the bridge plate, and the other is set on the side facing away from the bridge plate. The second fine-tuning guide rail frame 4 includes two second fine-tuning guide rails 41 extending horizontally and arranged in parallel on the front and back of the template assembly, one of which is set on the side facing the bridge plate, and the other is set 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 set on the side facing the bridge plate, and the other is set 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 driving shaft 62, one of which is set on the side facing the bridge plate, and the other is set on the side facing away from the bridge plate.

[0057] In some embodiments of the present invention, Fig. 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 plate.

[0058] Further, in a preferred embodiment of the present invention, Fig.14 , Fig.15 , Fig.18 as well as Fig.19 As shown, the docking positioning mechanism includes a first magnetic fixing frame 32 connected to the rail docking end of the first fine-tuning rail 31, a second magnetic fixing frame 42 connected to the rail docking end of the second fine-tuning rail 41, a third magnetic fixing frame 72 connected to the rail docking end of the positioning rail 71, and a fourth magnetic fixing frame 64 connected to the end of the adjustment rail 63, wherein the outer end surfaces 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. Fig.14 As shown, when the adjustment guide rail 63 is transitionally connected with the first fine-tuning guide rail 31, the fourth magnetic fixing frame 64 is opposite to the first magnetic fixing frame 32. At this time, the electromagnetic suction blocks 10 on the fourth magnetic fixing frame 64 and the first magnetic fixing frame 32 are energized and attracted and fixed together, which stabilizes and strengthens the connection between the adjustment guide rail 63 and the first fine-tuning guide rail 31.

[0059] In order to achieve accurate alignment between the guide rails, a precise alignment mechanism is provided between the guide rail butt end of the first fine-tuning guide rail 31, the guide rail butt end of the second fine-tuning guide rail 41, and the guide rail butt end of the positioning guide rail 71 and the end of the adjustment guide rail 63, respectively. Through the precise alignment mechanism, the first fine-tuning guide rail frame 3, the second fine-tuning guide rail frame 4, and the positioning guide rail frame 7 can be quickly and accurately aligned with the adjustment device 6, respectively, so as to complete the rapid connection and transition between the guide rails. Specifically, in a preferred embodiment of the present invention, as Fig.16 and Fig.19 As shown, the precise alignment mechanism includes a ball groove 631 provided at the end of the adjustment guide rail 63, a spring 632 provided in the ball groove 631, and a spring stopper ball 633 movably provided at the notch of the ball groove 631. The spring stopper ball 633 is fixedly connected to the spring 632, and the spring stopper ball 633 has a protruding portion of less than one-half of the ball body at the notch of the ball groove 631. When the spring stopper ball 633 is not subjected to force, the spring 632 is in a free state. To facilitate understanding of the precise alignment mechanism, the positioning guide rail 71 is used as an example for explanation. Fig.19 As shown in the example, a semicircular ball groove 20 is provided at the guide rail docking end of the positioning guide rail 71, and the semicircular ball groove 20 is adapted to the spherical protrusion of the spring limiting ball 633. When the adjustment guide rail 63 rotates to dock 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, and under the extrusion, the spring 632 is compressed, and the spring limiting ball 633 retracts into the ball groove 631. After the ball groove 631 and the semicircular ball groove 20 are completely aligned, the spring 632 restores its elastic deformation, the spring limiting ball 633 re-pops out part of the ball, and the protruding part of the ball fits into the semicircular ball groove 20, thereby quickly completing the alignment of the adjustment guide rail 63 and the positioning guide rail 71. After the alignment is completed, the electromagnetic suction block 10 on the third magnetic suction fixing frame 72 and the fourth magnetic suction fixing frame 64 is energized to complete the stable connection between the positioning guide rail 71 and the adjustment guide rail 63. Similarly, a semicircular ball groove 20 is respectively formed at the end of the guide rail butt end of the first fine-tuning guide rail 31 , the guide rail butt end of the second fine-tuning guide rail 41 , and the guide rail butt end of the positioning guide rail 71 .

[0060] Further, in a preferred embodiment of the present invention, Figure 1 As shown, the left and right ends of the frame 2 are provided with clamping plates 9 respectively. The clamping plates 9 at the two ends can be relatively close or relatively far away. By adjusting the clamping plates 9, the present invention can be applied to bridge plates 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 adjusted to be telescopic on both sides synchronously. Combined with the adaptive characteristics of the movable template assembly, the center of the clamping plate 9 can be aligned with the center of the bridge plate. Specifically, see Fig. 20 and Fig.21As shown, the clamping plate 9 is formed with a guide column 911 extending along the length direction of the sample 1 and a telescopic electric cylinder 92 arranged parallel to the guide column 911 at one end of the back side facing the sample 1. Figure 7 As shown, the end of the frame 2 is provided with a guide post installation opening 26 and an electric cylinder installation opening 27, wherein the guide post 911 is slidably adapted in the guide post installation opening 26, and the telescopic electric cylinder 92 is fixedly installed in the electric cylinder installation opening 27. When the spacing between the clamping plates 9 needs to be adjusted, the telescopic electric cylinder 92 is started to drive the guide post 911 of the clamping plate 9 to slide in the guide post installation opening 26 at the end of the frame 2, thereby realizing the clamping adjustment between the two relative clamping plates 9.

[0061] Furthermore, in order to facilitate the movement of the integral template device of the present invention, a plurality of roller grooves 24 are provided at the bottom of the frame 2 along its length direction, and universal wheels 25 are provided in the roller grooves 24. In order to facilitate installation and adapt to the drilling position where the system line angle changes after arching, such as Figure 4 and Fig.18 As shown, the surface of the template 1 is provided with grooves 113 at each guide rail corresponding to the first fine-tuning guide frame 3 and the second fine-tuning guide frame 4, and the side edge of the fixing plate 222 facing the bridge plate is provided with grooves 113, and each groove 113 is provided with a fine-tuning fixing mechanism. The fine-tuning fixing mechanism can provide installation stability for the first fine-tuning guide frame 3, the second fine-tuning guide frame 4 and the positioning guide frame 7 on the one hand, and on the other hand, under the influence of force, some positions on the bridge plate will produce arching. After the arching of the bridge plate causes the angle of the system line to change, the angle of the drilling position will also change. Figure 2 and Fig.24 The following is an example for explanation. If the corresponding Figure 2 The bridge slab on the left side of the vertical plate template 11 shown in the figure has an arch, and the drilling position on the bridge slab will also have an angle change. Fig.24 The two states shown in the figure are used to illustrate that the small circles at the four corners in (a) and (b) represent drilling positions, and the two vertical columns of straight lines and the two horizontal rows of straight lines represent the vertical sliding positioning plate 52 and the horizontal sliding positioning plate 51 respectively. In (a), it shows the angular relationship of the four drilling positions of the bridge plate in the unarched state, and in (b), it shows the angular relationship of the four drilling positions of the bridge plate in the arched state. From the change in the angle of the drilling position from (a) to (b), it can be seen that when the arch is formed, the positioning holes of the drilling positions with angles cannot be drilled simply by relying on the adjustment of the horizontal forward and reverse spiral screw assembly 57 and the vertical forward and reverse spiral screw assembly 58. At this time, it is also necessary to use Figure 2 The first fine-tuning guide rail 3 is completed with the aid of the fine-tuning fixing mechanism in the groove position 113 distributed in a straight line in the left area of ​​the vertical plate template 11. Figure 2The left area of ​​the vertical plate template 11 is shown to be slightly adjusted at an angle to accommodate the angled drilling positions on the bridge deck.

[0062] Specifically, the adjusting device 6 is fixedly docked with the first fine-tuning guide rail frame 3, and then the first fine-tuning guide rail frame 3 and the adjusting device 6 are synchronously rotated by a corresponding fine-tuning swing angle under the rotation adjustment of the adjusting device 6, so that the first fine-tuning guide rail frame 3 is Figure 2 The left side of the vertical plate template 11 shown generates a small angle which is the same as the swing angle of the adjustment device 6. Similarly, Figure 2 The system line angle adjustment of the right area of ​​the vertical plate template 11 shown is assisted by the fine-tuning fixing mechanism in the groove position 113 distributed in a straight line in the side area to assist the second fine-tuning guide frame 4 to complete the small angle adjustment. The system line angle adjustment of the positioning guide frame 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 assist the positioning guide frame 7 to complete the small angle adjustment.

[0063] Among them, as a preferred embodiment of the present invention, Fig.14 , Fig.18 , Fig.19 as well as Fig.23 As shown, the fine-tuning fixing mechanism in the groove position 113 includes an arc-shaped slide rail 114 with an arc and a slider 115 slidably connected to the arc-shaped slide rail 114, and 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 fine-tuning fixing mechanism at the corresponding position. Fig.13 As shown in the figure, since the first fine-tuning guide rail frame 3 and the adjusting device 6 rotate synchronously by a corresponding fine-tuning swing angle, and the first fine-tuning guide rail frame 3 has a relatively large swing amplitude at the end away from the rotation center of the adjusting device 6, the arc lengths of the arc-shaped slide rails 114 in each fine-tuning fixing mechanism corresponding to the first fine-tuning guide rail frame 3 are different. Specifically, the arc lengths of the arc-shaped slide rails 114 along the rotation center of the adjusting device 6 to the far end of the first fine-tuning guide rail frame 3 ( Fig.13 The arc length of the arc-shaped slide rail 114 in each fine-tuning fixing mechanism is gradually lengthened and has the same radius of curvature. The change in the system line angle caused by the arch is small (although small, it is still necessary to adjust the drill sleeve device 5). Fig.24 (a) to (b) angle adaptive adjustment), therefore, the first fine-tuning guide frame 3, the second fine-tuning guide frame 4 and the positioning guide frame 7 fine-tuning swing angle is also small, the swing amplitude is also small, so the curvature radius of the arc-shaped slide rail 114 is large, Fig.23 The rail shown in FIG.

[0064] The use process of the overall sample device of the present invention is as follows:

[0065] Step 1: The whole sample device is hoisted to the bridge plate position by a hoisting device, so that the universal wheel 25 contacts the plane where the lower edge of the bridge plate is located, and then the whole sample device is driven to move by the hoisting device so that it is attached to the bridge plate;

[0066] Step 2: Clamp the two ends of the bridge plate with the clamping plates 9 at both ends, and fix the electromagnet 8 on the bridge plate through electromagnetic attraction, so that the sample plate 1 and the bridge plate are positioned;

[0067] Step 3: The linear motor on the drill sleeve device 5 drives it to move on the first fine-tuning guide rail 31 on the first fine-tuning guide rail frame 3. When it moves to the corresponding vertical plate hole group window 111 where the vertical plate positioning hole group is to be drilled, the drill sleeve device 5 is fixed at the position, and the hole spacing of the drill sleeve device 5 is adjusted. Then, the vertical plate positioning holes are accurately drilled by the drill sleeve device 5;

[0068] Step 4: When it is necessary to drill the node plate positioning hole, 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, and then the drill sleeve device 5 is transferred from the first fine-tuning guide rail 31 to the adjustment guide rail 63, and the adjustment guide rail 63 is continued to be driven to rotate to a specified angle and stop, so that it is aligned with the positioning guide rail frame 7 on the node plate hole group window 121, and 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 hole is accurately drilled through the drill sleeve device 5.

[0069] It should be noted that in the embodiment of the present invention, the position of the groove position 113 is related to the position of the hole group on the template 1, rather than being set in isolation. That is, if the position of the hole group on the template 1 changes, the groove position 113 should also be adaptively changed accordingly. For example, Fig.25 As shown, the positions of the grooves 113 on the template 1 with different hole groups (dashed boxes in the figure) are also different accordingly. The general rule is that the grooves 113 are arranged on the trajectory of the drill sleeve device 5. The trajectory of the drill sleeve device 5 is different for the hole groups at different positions. Fig.25 In the figure, (a) shows the positional relationship in which the line connecting the groove position 113 and the hole group is a horizontal straight line in one embodiment, and (b) shows the positional relationship in which the line connecting the groove position 113 and the hole group is an oblique straight line in another embodiment.
