Description

Technical Field

[0001] This invention relates to the field of bridge steel structure processing equipment technology, and in particular to a drilling device and drilling method for bridge steel structures. Background Technology

[0002] A bridge generally refers to a structure erected over rivers, lakes, or seas to allow vehicles and pedestrians to pass smoothly. To adapt to the rapidly developing modern transportation industry, the term "bridge" has also come to refer to structures built across mountains, challenging geological conditions, or to meet other transportation needs, making travel more convenient. Bridges are constructed using steel structures. Before constructing multi-directional connections between steel structures, holes need to be drilled at corresponding locations within the steel structures, thus requiring a drilling device specifically designed for bridge steel structures.

[0003] A positioning and drilling device for bridge steel structure processing, disclosed in Chinese Patent Publication No. CN217166574U, includes a support base, a support plate fixedly connected to the support base, a movable groove on the support plate, a steel plate slidably connected inside the movable groove, a positioning sleeve slidably sleeved on the outer side of the support plate, the positioning sleeve contacting the steel plate, a guide block fixedly connected to the positioning sleeve, a top plate fixedly connected to the support plate, a connecting plate fixedly connected to the positioning sleeve, and a support rod slidably connected inside the connecting plate. This application, by incorporating a positioning sleeve, allows the steel plate to be drilled to be placed into the movable groove on the support plate, enabling the positioning sleeve to position the steel plate and effectively preventing movement during processing. This solves the problem of existing drilling devices for bridge steel structure processing lacking a positioning mechanism.

[0004] However, this application has the following problems: First, it can only perform positioning drilling on long or square steel structures. When drilling on irregularly shaped steel structures, especially S-shaped ones, the fixing effect is poor and lacks strong stability. The steel structure is prone to displacement during drilling, affecting the drilling accuracy. Second, when drilling multiple holes at equal intervals on the steel structure, this application requires repeated positioning drilling operations, resulting in low drilling efficiency. There is a lack of a bridge steel structure drilling device that can provide a high degree of clamping and fixing effect to improve drilling accuracy when drilling on steel structures of different shapes, especially S-shaped ones, and can perform simultaneous drilling on multiple equally spaced holes to improve drilling efficiency. Summary of the Invention

The clamping member is made of a flexible material.

[0015] A drilling method for bridge steel structures includes the following steps:

[0016] S1: When drilling into the steel structure, the steel structure is first placed on top of the limiting box, with two limiting blocks located on both sides of the steel structure. The dual-axis motor is controlled to drive the two first lead screws to rotate synchronously, thereby driving the two limiting blocks set on the drive block to move synchronously to both sides of the steel structure until they contact the side ends of the steel structure. This achieves the initial limiting and fixing of the steel structure, so as to avoid large displacement of the steel structure during drilling and affecting the drilling operation.

[0017] S2: When drilling holes in a steel structure, the drilling position on the steel structure must first be located. By controlling the first motor to drive the second lead screw to rotate, the first positioning block will slide laterally along the direction of the limit rod, thereby causing the mounting sleeve to slide laterally at the bottom of the mounting frame. The sliding is relatively stable, thus controlling the drilling machine set at the bottom of the mounting sleeve to slide laterally, thereby achieving the lateral positioning of the drilling position on the steel structure.

[0018] S3: After the drilling position is horizontally positioned by the horizontal positioning component, the longitudinal positioning component connected to the drilling machine is controlled to work, and the third motor is controlled to drive the fourth lead screw to rotate, thereby driving the second positioning block to move, which in turn drives the drilling machine set at the bottom of the second positioning block to move longitudinally, further realizing the precise positioning of the drilling machine and the drilling position on the steel structure.

[0019] S4: After the drilling machine completes the positioning work with the drilling position on the steel structure, the electric push rod is controlled to drive the drilling machine installed below it to descend to the drilling position so that the drilling machine can perform drilling operations on the drilling position on the steel structure.

[0020] S5: After the drilling machine is precisely positioned with the drilling position through the cooperation of the lifting assembly, the horizontal positioning assembly, and the vertical positioning assembly, in order to further improve the stability during drilling, the second drive assembly is controlled to drive the two clamping parts to clamp and fix the end of the steel structure from both sides of the drilling position. According to the shape of the steel structure surface, the adjusting rod can be controlled to move in the connecting sleeve with the help of the spring, thereby further adaptively adjusting the movement stroke of the clamping parts, so as to maximize the fixation of the two clamping parts from both sides of the drilling position of the steel structure. The fixing effect can also be achieved for different shapes. Furthermore, by setting the clamping parts to a flexible material with high ductility, the clamping parts can fit as closely as possible to the surface of the irregular steel structure and avoid damage to its surface.

[0021] S6: When drilling multiple holes at equal intervals is required, the second motor is controlled to drive the third lead screw to rotate, thereby moving several equidistant blocks horizontally towards or away from the connecting block with the connecting block as the base point. During the movement, the rotation of the first and second connecting rods is coordinated to ensure that each equidistant block moves the same distance during the movement. This allows the drilling machine, which is set at the bottom of the connecting block and several equidistant blocks, to move at equal intervals, thus achieving the multi-hole drilling operation at equal intervals on the steel structure.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] Firstly, when using this device, the irregularly shaped steel structure is initially placed on the steel structure limiting device for preliminary positioning and fixation to prevent significant displacement of the steel structure during drilling, which could affect the drilling operation. For single-hole drilling, the cooperation of the horizontal and vertical positioning components allows the drilling machine to accurately position the drilling location. The lifting component controls the drilling machine to approach the drilling location, and then the drilling machine performs the drilling operation. During the drilling process, the irregularly shaped positioning clamping component clamps both sides of the drilling location on the steel structure, and can be adaptively adjusted according to the shape of the steel structure, thereby ensuring accurate drilling at the designated location. The periphery of the drilling position is in a relatively stable and fixed state to avoid the steel structure from shifting during drilling, which would affect the drilling quality. When multiple holes need to be drilled at equal intervals, the equal-interval drilling assembly can control multiple drilling machines to move at equal intervals. With the cooperation of the horizontal positioning assembly and the vertical positioning assembly, they are aligned with multiple drilling positions, thereby realizing equal-interval multi-hole drilling operations. This device can provide a high degree of clamping and fixing effect to improve drilling accuracy when drilling steel structures of different shapes, especially S-shaped ones. It can also perform synchronous drilling of multiple equally interval drilling positions, thereby improving drilling efficiency.

[0024] Secondly, when drilling into the steel structure, the steel structure is first placed on top of the limiting box, with two limiting blocks located on either side of the steel structure. The dual-axis motor is controlled to drive the two first lead screws to rotate synchronously, thereby moving the two limiting blocks set on the drive block synchronously to the sides of the steel structure until they contact the side ends of the steel structure. This achieves initial limiting and fixing of the steel structure, preventing large displacement of the steel structure during drilling and affecting the drilling operation. By setting flexible silicone pads at the limiting ends of the limiting blocks, scratches on the surface of the steel structure can be avoided when initially clamping and limiting the side ends of the steel structure, thus affecting the finished quality of the steel structure.

[0025] Thirdly, when drilling holes in the steel structure, the drilling positions on the steel structure must first be positioned. By controlling the first motor to drive the second lead screw to rotate, the first positioning block will slide laterally along the direction of the limit rod, thereby causing the mounting sleeve to slide laterally at the bottom of the mounting frame. The sliding is relatively stable, thus controlling the drilling machine set at the bottom of the mounting sleeve to slide laterally, thereby achieving lateral positioning of the drilling position on the steel structure. After the drilling position is laterally positioned by the lateral positioning component, the longitudinal positioning component connected to the drilling machine is controlled to work, controlling the third motor to drive the fourth lead screw to rotate, thereby moving the second positioning block, thereby causing the drilling machine set at the bottom of the second positioning block to move longitudinally, further achieving precise positioning of the drilling machine and the drilling position on the steel structure.

[0026] Fourth, after the drilling machine completes the positioning work with the drilling position on the steel structure, the drilling machine installed below it is driven to descend to the drilling position by controlling the electric push rod, so that the drilling machine can perform drilling operations on the drilling position on the steel structure.

[0027] Fifth, when drilling multiple holes at equal intervals is required, the second motor is controlled to drive the third lead screw to rotate, thereby moving several equidistant blocks horizontally towards or away from the connecting block with the connecting block as the base point. During the movement, the rotation of the first and second connecting rods is coordinated to ensure that each equidistant block moves the same distance during the movement. This allows the drilling machine, which is set at the bottom of the connecting block and several equidistant blocks, to move at equal intervals, thus enabling the drilling operation of multiple holes at equal intervals on the steel structure.

[0028] Sixth, after the drilling machine is precisely positioned with the drilling position through the cooperation of the lifting assembly, the horizontal positioning assembly, and the vertical positioning assembly, in order to further improve the stability during drilling, the second drive assembly is controlled to drive the two clamping parts to clamp and fix the ends of the steel structure from both sides of the drilling position. According to the shape of the steel structure surface, the adjusting rod can be controlled to move in the connecting sleeve with the help of the spring, thereby further adapting the movement stroke of the clamping parts, so as to ensure that the two clamping parts fix the steel structure from both sides of the drilling position to the greatest extent. The fixing effect can also be achieved for different shapes. Furthermore, by setting the clamping parts to a flexible material with high ductility, the clamping parts can fit as closely as possible to the surface of the irregular steel structure and avoid damage to its surface.

[0047] Reference Figures 1 to 10As shown, a drilling device for bridge steel structures includes a drilling machine 1, a steel structure limiting device 2, and a non-standard driving drilling device 3. The steel structure limiting device 2 is disposed on a horizontal plane, and the non-standard driving drilling device 3 is disposed above the steel structure limiting device 2. The non-standard driving drilling device 3 includes a lateral positioning component 31, a lifting component 32, an equidistant drilling component 33, a longitudinal positioning component 34, and a non-standard positioning clamping component 35. The lateral positioning component 31 is disposed above the steel structure limiting device 2, and the lifting component 32 is disposed at the bottom of the lateral positioning component 31. The equidistant drilling assembly 33 is disposed at the bottom of the lifting assembly 32. Several longitudinal positioning assemblies 34 and irregularly shaped positioning clamping assemblies 35 are provided. Several longitudinal positioning assemblies 34 are equidistantly disposed at the bottom of the equidistant drilling assembly 33. Each longitudinal positioning assembly 34 has an irregularly shaped positioning clamping assembly 35 at its bottom. Several drilling machines 1 are provided, and several drilling machines 1 are respectively disposed at the bottom of several irregularly shaped positioning clamping assemblies 35. In use, the irregularly shaped steel structure 4 is first placed on the steel structure limiting device 2 for initial limiting and fixing to avoid… Significant displacement of the steel structure during drilling affects the drilling operation. For single-hole drilling, the cooperation of the transverse positioning component 31 and the longitudinal positioning component 34 allows the drilling machine 1 to be precisely positioned at the drilling location. The lifting component 32 controls the drilling machine 1 to approach the drilling location and then drills the hole. During drilling, the irregular-shaped positioning clamping component 35 clamps the two sides of the drilling location on the steel structure and can be adjusted according to the shape of the steel structure, ensuring that the periphery of the drilling location remains relatively stable and fixed during drilling. To prevent steel structure misalignment during drilling and thus affect drilling quality, when multiple holes need to be drilled at equal intervals, the equal-interval drilling assembly 33 can control multiple drilling machines 1 to move at equal intervals. Furthermore, with the cooperation of the transverse positioning assembly 31 and the longitudinal positioning assembly 34, they are aligned with multiple drilling positions, thereby achieving equal-interval multi-hole drilling operations. This device provides a high degree of clamping and fixing effect to improve drilling accuracy when drilling steel structures of different shapes, especially S-shaped ones. It also enables simultaneous drilling of multiple equally interval drilling positions, improving drilling efficiency.

Each drive block 223 is threadedly connected to a first lead screw 222. The tops of both drive blocks 223 pass through the top of the limiting box 21 and slide in cooperation with it. There are two limiting blocks 23, each of which is set on the top of one drive block 223 and the two limiting blocks 23 are symmetrically arranged. When drilling the steel structure, the steel structure is first placed on the top of the limiting box 21, and the two limiting blocks 23 are located on both sides of the steel structure. The dual-axis motor 221 is controlled to drive the two first lead screws 222 to rotate synchronously, thereby driving the two limiting blocks 23 set on the drive blocks 223 to move synchronously to both sides of the steel structure until they contact the side ends of the steel structure, thereby achieving the initial limiting and fixing of the steel structure to avoid large displacement of the steel structure during drilling and affecting the drilling operation.

[0049] Reference Figure 3 As shown, preferably, each limiting block 23 has a silicone pad at its limiting end; by providing a flexible silicone pad at the limiting end of the limiting block 23, the limiting end of the limiting block 23 can avoid scratching the surface of the steel structure and affecting the finished quality of the steel structure when the side end of the steel structure is initially clamped and limited.

The mounting sleeve 316 is laterally slidably engaged with the bottom of the mounting frame 311. When drilling holes in the steel structure, the drilling position on the steel structure must first be positioned. By controlling the first motor 312 to work, the second lead screw 313 is rotated, thereby driving the first positioning block 315 to slide laterally along the direction of the limiting rods 314, thereby driving the mounting sleeve 316 to slide laterally at the bottom of the mounting frame 311. The sliding is relatively stable, thereby controlling the drilling machine 1 set at the bottom of the mounting sleeve 316 to slide laterally, thereby achieving the lateral positioning of the drilling position on the steel structure.

After the drilling machine 1 completes the positioning work with the drilling position on the steel structure, the drilling machine 1 installed below it is driven to descend to close to the drilling position by controlling the electric push rod 321, so that the drilling machine 1 can perform drilling operation on the drilling position on the steel structure.

During the movement, the rotation of the first connecting rod 337 and the second connecting rod 338 is coordinated to ensure that each equidistant block 336 moves the same distance during the movement. This enables the drilling machine 1, which is set at the bottom of the connecting block 335 and several equidistant blocks 336, to move at equal intervals, thereby realizing the multi-hole drilling operation at equal intervals on the steel structure.

[0056] A drilling method for bridge steel structures includes the following steps:

[0057] S1: When drilling into the steel structure, the steel structure is first placed on top of the limiting box 21, with two limiting blocks 23 located on both sides of the steel structure. The dual-axis motor 221 is controlled to drive the two first lead screws 222 to rotate synchronously, thereby driving the two limiting blocks 23 set on the drive block 223 to move synchronously to both sides of the steel structure until they contact the side ends of the steel structure, thus achieving preliminary limiting and fixing of the steel structure to avoid large displacement of the steel structure during drilling, which would affect the drilling operation.

[0058] S2: When drilling holes in a steel structure, the drilling position on the steel structure must first be located. By controlling the first motor 312 to drive the second lead screw 313 to rotate, the first positioning block 315 will slide laterally along the direction of the limit rod 314, thereby causing the mounting sleeve 316 to slide laterally at the bottom of the mounting frame 311. The sliding is relatively stable, thereby controlling the drilling machine 1 set at the bottom of the mounting sleeve 316 to slide laterally, thus achieving the lateral positioning of the drilling position on the steel structure.

[0059] S3: After the horizontal positioning component 31 is used to horizontally position the drilling position, the vertical positioning component 34 connected to the drilling machine 1 is controlled to work, and the third motor 343 is controlled to work to drive the fourth lead screw 342 to rotate, thereby driving the second positioning block 344 to move, thereby driving the drilling machine 1 set at the bottom of the second positioning block 344 to move vertically, further realizing the precise positioning of the drilling machine 1 and the drilling position on the steel structure.

[0060] S4: After the drilling machine 1 completes the positioning work with the drilling position on the steel structure, the electric push rod 321 is controlled to drive the drilling machine 1 installed below it to descend to the drilling position so that the drilling machine 1 can perform drilling operations on the drilling position on the steel structure.

[0061] S5: After the drilling machine 1 is precisely positioned with the drilling position through the cooperation of the lifting component 32, the horizontal positioning component 31 and the vertical positioning component 34, in order to further improve the stability during drilling, the second drive component 352 is controlled to drive the two clamping parts 3534 to clamp and fix the end of the steel structure from both sides of the drilling position. According to the shape of the steel structure surface, the adjusting rod 3532 can be controlled to move in the connecting sleeve 3531 with the cooperation of the spring 3533, so as to further adaptively adjust the movement stroke of the clamping parts 3534, thereby maximizing the fixation of the two clamping parts 3534 from both sides of the drilling position of the steel structure. The fixing effect can also be achieved for different shapes. Furthermore, by setting the clamping parts 3534 to a flexible material with high ductility, the clamping parts 3534 can fit as close as possible to the surface of the irregular steel structure and avoid damage to its surface.

[0062] S6: When drilling multiple holes at equal intervals is required, the second motor 334 is controlled to drive the third lead screw 332 to rotate, thereby driving several equidistant blocks 336 to move horizontally towards or away from the connecting block 335 with the connecting block 335 as the base point. During the movement, the rotation of the first connecting rod 337 and the second connecting rod 338 is coordinated to ensure that each equidistant block 336 moves the same distance during the movement. This enables the drilling machine 1, which is set at the bottom of the connecting block 335 and several equidistant blocks 336, to move at equal intervals, thereby realizing the multi-hole drilling operation of the steel structure at equal intervals.
