Description

Technical Field

[0001] This utility model relates to the technical field of bridge deck drilling equipment, and specifically to a drill sleeve device for drilling bridge decks. Background Technology

[0002] In steel structure bridges, the requirements for connecting plates vary depending on the connection location. They can be broadly categorized into three types: main longitudinal beam connecting plates, transverse beam connecting plates, and secondary longitudinal beam connecting plates. During assembly, except for the horizontal plate ribs between the main longitudinal beams which require drilling during local assembly, drilling templates are used to complete the drilling of the hole groups in other areas. Because of varying stress conditions, the camber of the members differs, resulting in different member system lines within the same project. This leads to significant variations in the spacing between holes in the hole group, requiring flexible adjustments during drilling. This places extremely high demands on the drilling workers in the workshop, greatly increasing the chance of drilling errors.

[0003] For example, the utility model patent with authorization announcement number CN219379051U, "A drilling device for bridge template processing", adopts single-hole drilling. The spacing between different holes in the hole group needs to be manually calibrated before drilling, which makes drilling positioning more troublesome and the positioning accuracy of the holes is low during operation. Utility Model Content

[0004] To improve the drilling accuracy of bridge slab hole groups, this utility model provides a drilling sleeve device for drilling bridge slab holes.

[0005] The technical solution adopted by this utility model to achieve the above-mentioned technical effects is:

[0006] A drill sleeve device for drilling holes in bridge decks includes two vertically arranged first positioning plates and two horizontally arranged second positioning plates. Each of the first and second positioning plates has a strip-shaped hole extending along its length at its end. The strip-shaped holes at the ends of the first and second positioning plates form a cross, and a drill sleeve fixture for positioning the drill bit is provided at the intersection. A first spacing adjustment mechanism for adjusting the relative distance between the two first positioning plates is connected to the two first positioning plates, and a second spacing adjustment mechanism for adjusting the relative distance between the two second positioning plates is connected to the two second positioning plates.

[0007] Preferably, in the above-mentioned drill bushing device for drilling bridge decks, the drill bushing fixture includes a dumbbell-shaped clamp and a drill bushing nested in the clamp.

[0008] Preferably, in the above-mentioned drill sleeve device for drilling bridge slabs, the periphery of the column is provided with at least three jaw grooves, and the jaw grooves are provided with jaws for clamping the drill sleeve.

[0009] Preferably, in the above-mentioned drill sleeve device for drilling bridge slabs, the upper limiting disc of the clamp is provided with distance sensors in four directions (up, down, left, and right) for positioning the distance between adjacent drill sleeves.

[0010] Preferably, in the above-described drill sleeve device for drilling bridge decks, the first spacing adjustment mechanism is located behind the second spacing adjustment mechanism, and the two form a cross. The first spacing adjustment mechanism is slidably connected to a horizontal linear guide rail by at least two sliders.

[0011] Preferably, in the above-mentioned drill sleeve device for drilling bridge decks, the second spacing adjustment mechanism is fixed on a long strip support, the two ends of the support are formed with protruding ends, the two ends of the second spacing adjustment mechanism are respectively fixed on the protruding ends of the corresponding ends, and the middle position of the support is formed with an assembly position for assembling the first spacing adjustment mechanism.

[0012] Preferably, in the above-mentioned drill sleeve device for drilling bridge decks, the structure of the second spacing adjustment mechanism is the same as that of the first spacing adjustment mechanism. The first spacing adjustment mechanism includes a long strip seat and a positive and negative spiral screw provided on the long strip seat. The two ends of the positive and negative spiral screws are a positive spiral rod segment and a negative spiral rod segment, respectively. One of the first positioning plates is threadedly connected to the positive spiral rod segment through the bottom screw slide, and the other first positioning plate is threadedly connected to the negative spiral rod segment through the bottom screw slide.

[0014] The beneficial effects of this utility model are as follows: The template component of this utility model uses a panel that mimics the shape of a bridge plate, and arranges different groups of holes and windows, as well as multiple linearly distributed panel grooves and a system line angle fine-tuning mechanism located therein. This allows for fine-tuning of the system line angle of the guide rail, thereby assisting the matching drilling device in drilling holes in the upper and lower chord plates of the entire bridge project. One set of templates can assist in drilling holes in different types of plates, eliminating the need for multiple positioning holes and templates. Attached Figure Description

[0025] Please see Figure 1 and Figure 3As shown in the figure, an embodiment of this utility model proposes a drill sleeve device for drilling holes in bridge slabs. This drill sleeve device includes two vertically arranged first positioning plates 1 and two horizontally arranged second positioning plates 2. Each end of the first positioning plate 1 and the second positioning plate 2 has a strip-shaped hole 3 extending along its length. The strip-shaped holes 3 at the ends of the first positioning plate 1 and the second positioning plate 2 form a cross, and a drill sleeve fixture 4 for positioning the drill bit is provided at the intersection. To facilitate adjustment of the spacing between the drill sleeve fixtures 4 and to achieve positioning of the locating hole to be drilled, as shown... Figure 3 As shown, a first spacing adjustment mechanism 6 for adjusting the relative distance between the two first positioning plates 1 is connected to the two first positioning plates 1, and a second spacing adjustment mechanism 5 for adjusting the relative distance between the two second positioning plates 2 is connected to the two second positioning plates 2. By adjusting the distance between the two first positioning plates 1 through the first spacing adjustment mechanism 6 and adjusting the distance between the two second positioning plates 2 through the second spacing adjustment mechanism 5, the position of the drill bushing tool 4 located at the four corners can be adjusted, thereby achieving flexible hole position adjustment. Specifically, as shown... Figure 3 As shown, when a horizontal strip hole 3 and a vertical strip hole 3 form a cross, a square locking hole is formed at the intersection. The drill bushing fixture 4 is locked in this square locking hole. When the first positioning plate 1 and the second positioning plate 2 slide, they can drive the drill bushing fixture 4 to slide within the locking hole. Figure 3 As shown, two vertically positioned first positioning plates 1 and two horizontally positioned second positioning plates 2 intersect to form a cross, creating four cross-shaped holes for installing the drill bushing fixtures 4. These four cross-shaped holes are connected sequentially to form a rectangle. By adjusting the relative left-right spacing of the two vertically positioned first positioning plates 1, the distance between the two drill bushing fixtures 4 in the left column and the two in the right column can be adjusted accordingly. Similarly, by adjusting the relative vertical spacing of the two horizontally positioned second positioning plates 2, the distance between the two upward-moving drill bushing fixtures 4 and the two downward-moving drill bushing fixtures 4 can be adjusted accordingly, thus completing the hole spacing adjustment among the four drill bushing fixtures 4.

[0026] Furthermore, in a preferred embodiment of this utility model, such as Figure 6 and Figure 7 As shown, the drill bushing fixture 4 includes a dumbbell-shaped clamp 41 and a drill bushing 42 nested in the clamp 41. The drill bushing 42 is used to position the hole to be drilled. After positioning, the drill bit is inserted into the drill bushing 42 to accurately drill the positioning hole at the current positioning point. Specifically, as shown... Figure 7As shown, the clamp 41 has limiting discs 411 formed at both its upper and lower ends, and a column 412 connecting the two limiting discs 411 in the middle. The column 412 is movably engaged in the cross-shaped slots 3, and a through hole for installing the drill sleeve 42 is formed in the column 412. To facilitate clamping and fixing the drill sleeve 42, at least three claw grooves 413 are provided on the periphery of the column 412, and claws 43 for clamping the drill sleeve 42 are provided in the claw grooves 413. A suitable size drill sleeve 42 can be selected according to the size of the positioning hole to be drilled. As a preferred embodiment of this utility model, as shown... Figure 6 and Figure 7 As shown, the number of claw slots 413 is set to four.

[0027] Furthermore, in a preferred embodiment of this utility model, such as Figure 6 and Figure 7 As shown, the upper limiting disk 411 of the clamp 41 is provided with distance sensors 44 in the four directions of up, down, left and right for positioning the distance between adjacent drill sleeves. Through the sensing of the distance sensors 44, the distance between drill sleeves 42 can be precisely controlled.

[0028] Specifically, such as Figure 2 and Figure 3 As shown, the first spacing adjustment mechanism 6 is located behind the second spacing adjustment mechanism 5, forming a cross. The first spacing adjustment mechanism 6 is slidably connected to a horizontal linear guide rail 8 via at least two sliders 81. Specifically, as... Figure 4 As shown, the second pitch adjustment mechanism 5 is fixed on a long strip-shaped support 7. Both ends of the support 7 have protruding ends 71. The two ends of the second pitch adjustment mechanism 5 are respectively fixed to the corresponding protruding ends 71. A mounting position 72 for assembling the first pitch adjustment mechanism 6 is formed in the middle of the support 7. The first pitch adjustment mechanism 6 is fed through this mounting position 72 and is fixed at the center of the two in a cross shape.

[0029] Furthermore, in a preferred embodiment of this utility model, such as Figure 5As shown, the first spacing adjustment mechanism 6 includes a long strip base 61 and a forward and reverse helical screw 62 mounted on the long strip base 61. The two ends of the forward and reverse helical screw 62 are a forward helical rod segment 621 and a reverse helical rod segment 622, respectively. One first positioning plate 1 is threadedly connected to the forward helical rod segment 621 via a bottom screw slide, and the other first positioning plate 1 is threadedly connected to the reverse helical rod segment 622 via a bottom screw slide. The long strip base 61 has guide rail seats 63 on both sides of the forward and reverse helical screws 62. The guide rail seats 63 have guide rail grooves 631, and the screw slides have guide rail sliders that slide within the guide rail grooves 631. In a preferred embodiment of this utility model, the structure of the second spacing adjustment mechanism 5 is the same as that of the first spacing adjustment mechanism 6, and will not be described again here.
