[0002] In bridge construction projects, steel formwork serves as the core mold for concrete pouring and forming. Its precision and quality directly affect the dimensional stability and appearance quality of the bridge structure. During the fabrication and installation of steel formwork, it is often necessary to drill a large number of bolt holes, positioning holes, connection holes, etc., according to design requirements for formwork splicing, tie rod fixing, or installation of auxiliary components.

[0003] A search revealed Chinese patent CN219541750U, which discloses a drilling device for bridge steel formwork. This device has a simple structure and is easy to operate. It can simultaneously fix multiple bridge steel formwork pieces and drill them one by one by the drilling mechanism, reducing the frequency of steel formwork replacement and effectively improving the drilling efficiency of steel formwork. However, when fixing the steel formwork, it only fixes both sides, which can easily cause the steel formwork to vibrate up and down during the drilling process, thus affecting the drilling accuracy. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a drilling device for bridge steel formwork, which mainly solves the problem that when fixing steel formwork, only fixing its two sides can easily cause the steel formwork to vibrate up and down during the drilling process, thus affecting the drilling accuracy.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A drilling device for bridge steel formwork includes a base frame, a fixed frame fixedly connected to the base frame, a side clamping assembly for fixing the side of the steel formwork between the inner walls of the two sides of the base frame, an upper clamping assembly for fixing the upper surface of the steel formwork on the side clamping assembly, a pre-clamping assembly for pre-fixing the steel formwork on the side clamping assembly, a transverse moving assembly on the fixed frame and located above it, a drilling assembly for drilling holes in the steel formwork on the transverse moving assembly, and a conveying assembly for conveying the steel formwork between the inner walls of the two sides of the base frame and located in the middle of the side clamping assembly.

[0006] Furthermore, the side clamping assembly includes two symmetrical sliding rods fixedly connected between the inner walls of both sides of the base frame, two symmetrical slide rails slidably connected to the two sliding rods, and multiple support rods fixedly connected to the upper surface of each of the two slide rails, with side clamping plates fixedly connected to the top of the multiple support rods in the same group.

[0007] Based on the aforementioned scheme, a bidirectional lead screw is rotatably connected between the inner walls of the two sides of the base frame via bearings, and the bidirectional lead screw passes through two slides and is threadedly connected to them. A drive motor is fixedly connected to one side of the base frame to enable the bidirectional lead screw to rotate forward and backward along the axial direction.

[0008] As a further embodiment of the present invention, the upper clamping assembly includes two L-shaped plates 1, which are respectively fixedly connected to the middle position of the upper surface of the side clamping plate. A cylinder 1 is fixedly connected to the top outer wall of the L-shaped plate 1. The output end of the cylinder 1 passes through the top wall of the L-shaped plate 1 and is fixedly connected to an L-shaped upper clamping plate. Two L-shaped plates 2 are fixedly connected to both ends of the upper surface of the side clamping plate. Guide rods are fixedly connected to both ends of the top wall of the L-shaped upper clamping plate, and the two guide rods pass through the two L-shaped plates 2 respectively and are slidably connected to them.

[0009] Furthermore, the pre-clamping assembly includes multiple round rods that are slidably connected to the side clamping plate. One end of each round rod is fixedly connected to an L-shaped lower clamping plate. Multiple clearance grooves are provided on one side of the side clamping plate. Springs are fixedly connected between the clearance grooves and the L-shaped lower clamping plate.

[0010] Based on the aforementioned scheme, the transverse component includes a square frame fixedly connected to a fixed frame, an I-shaped slider slidably connected inside the square frame, a threaded rod rotatably connected between the two inner walls of the square frame via bearings, and a second drive motor fixedly connected to one outer wall of the square frame to cause the threaded rod to rotate forward and backward along the axial direction.

[0011] As a further embodiment of the present invention, the drilling assembly includes a second cylinder fixedly connected to the upper surface of the I-shaped slider, the output end of the second cylinder being fixedly connected to a connecting frame through the lower surface of the I-shaped slider, a third drive motor being fixedly connected to the bottom inner wall of the connecting frame, and the output end of the third drive motor being keyed to a drilling head through the bottom wall of the connecting frame.

[0012] Furthermore, the conveying assembly includes a horizontal plate 1 fixedly connected to the middle position between the inner walls of both sides of the base frame, and a horizontal plate 2 fixedly connected between the inner walls of both sides of the base frame and at the positions on both sides of the horizontal plate 1. Two round rods 2 are slidably connected through each of the two horizontal plates 2. A connecting frame is fixedly connected to the top of the multiple round rods 2. Support columns are fixedly connected to the four corners of the upper surface of the connecting frame. A conveyor belt is fixedly connected to the top of the multiple support columns. A cylinder 3 is fixedly connected to the lower surface of the horizontal plate 1 to move the connecting frame up and down.

[0013] Compared with the prior art, the present invention provides a drilling device for bridge steel formwork, which has the following advantages: 1. The present invention applies vertical pressure through the upper clamping component, which can effectively prevent the steel template from vibrating or shifting due to force during the drilling process, thus ensuring the accuracy of the processing dimensions.

[0014] 2. The present invention restricts the vertical and horizontal movement of the steel template by using the upper clamping component and the pre-clamping component together. The precise positioning and stable clamping can greatly reduce the scrap caused by clamping deviation.

[0015] 3. The present invention drives the drilling assembly to move laterally by means of a transverse moving component, which can complete the multi-hole processing of the entire transverse range of the steel template in one clamping, reducing the auxiliary time for disassembling and reassembling the steel template.

[0016] 4. The present invention, through its conveying components, can automatically complete the loading and unloading of steel templates, reducing manual operation time and avoiding equipment waiting time caused by slow manual loading and unloading speed, thereby realizing automated connection of the production process and effectively improving production efficiency.

[0017] 5. The present invention, through the provision of an L-shaped lower clamp, can prevent the steel formwork from falling off when it is initially loosened, thus protecting the steel formwork. Attached Figure Description

[0023] Please see Figures 1-6As shown, a bridge steel formwork drilling device includes a base frame 1, a fixing frame 2 fixedly connected to the base frame 1 by bolts, a side clamping assembly 3 for fixing the side of the steel formwork between the inner walls of the two sides of the base frame 1, an upper clamping assembly 4 for fixing the upper surface of the steel formwork on the side clamping assembly 3, and a pre-clamping assembly 5 for pre-fixing the steel formwork on the side clamping assembly 3. A transverse moving assembly 6 is provided on the fixing frame 2 at the upper position, and a drilling assembly 7 for drilling holes in the steel formwork is provided on the transverse moving assembly 6. A conveying assembly 8 for conveying the steel formwork is provided between the inner walls of the two sides of the base frame 1 at the middle position of the side clamping assembly 3. When drilling is required, the steel formwork is first conveyed to the middle by the conveying assembly 8, and then the steel formwork is fixed on multiple sides by the side clamping assembly 3, the upper clamping assembly 4 and the pre-clamping assembly 5. After the fixing is completed, the drilling assembly 7 is sent to the required position by the transverse moving assembly 6, and the drilling operation can be carried out.

[0024] In this invention, the side clamping assembly 3 includes two symmetrical sliding rods 301 that are fixedly connected to the inner walls of both sides of the base frame 1 by bolts. Two symmetrical slide frames 302 are slidably connected to the two sliding rods 301. Multiple support rods 303 are fixedly connected to the upper surface of each of the two slide frames 302 by bolts. The top ends of the multiple support rods 303 in the same group are fixedly connected to side clamping plates 304 by bolts. When the steel template is sent above the side clamping assembly 3, the drive motor 306 is started to drive the bidirectional lead screw 305 to rotate.

[0025] Furthermore, when it is necessary to move the two slides 302 synchronously, a bidirectional lead screw 305 is rotatably connected between the inner walls of both sides of the base frame 1 through bearings, and the bidirectional lead screw 305 passes through the two slides 302 and is threadedly connected to them. A drive motor 306 that causes the bidirectional lead screw 305 to rotate forward and backward along the axial direction is fixedly connected to one side of the base frame 1 by bolts. During the rotation of the bidirectional lead screw 305, the two slides 302 are driven to move closer synchronously along the slide bar 301, and then the pre-clamping assembly 5 is driven to move closer to each other synchronously through the side clamping plate 304.

[0026] To address the issue of steel templates vibrating during drilling, which can affect drilling accuracy, this invention employs an upper clamping assembly 4 comprising two L-shaped plates 401 bolted to the middle of the upper surface of a side clamping plate 304. A cylinder 402 is bolted to the top outer wall of each L-shaped plate 401. The output end of the cylinder 402 passes through the top wall of the L-shaped plate 401 and is bolted to an L-shaped upper clamping plate 403. Two L-shaped plates 404 are bolted to both ends of the upper surface of the side clamping plate 304. Guide rods 405 are bolted to both ends of the top wall of the upper clamping plate 403. The two guide rods 405 pass through the two L-shaped plates 404 and are slidably connected to them. After clamping both sides of the steel template, the cylinder 402 is activated to extend, thereby driving the L-shaped upper clamping plate 403 at its end to move downward. After it comes into close contact with the steel template, the upper surface of the steel template is tightly clamped. By applying vertical pressure through the upper clamping assembly 4, the steel template can be effectively prevented from vibrating or shifting due to force during drilling, thus ensuring the accuracy of the processing dimensions.

[0027] To pre-fix the steel template, the present invention employs a pre-clamping assembly 5, comprising multiple round rods 501 that are slidably connected to the side clamping plate 304. One end of each round rod 501 is bolted to an L-shaped lower clamping plate 502. Multiple clearance grooves 503 are provided on one side of the side clamping plate 304, and springs 504 are welded between the clearance grooves 503 and the L-shaped lower clamping plate 502. After the pre-clamping assembly 5 moves to a position where it can catch the steel template, the drive motor 306 is turned off, and the cylinder 807 is activated to retract, causing the conveyor belt 806 to move downwards, thereby lowering the steel template. During the downward movement of the steel template, it is pre-clamped. The L-shaped lower clamping plate 502 in the holding component 5 catches the steel template, and the cylinder 807 continues to retract, causing the conveyor belt 806 to move to the bottom. Then, the drive motor 306 is started again to move the side clamping plate 304. When the two L-shaped lower clamping plates 502 are in contact on both sides of the steel template, the movement will compress the spring 504 and retract it. When the L-shaped lower clamping plate 502 and the side clamping plate 304 are in close contact, the clamping operation on both sides of the steel template is completed. Through the cooperation of the upper clamping component 4 and the pre-clamping component 5, the vertical and horizontal movement of the steel template is restricted. The precise positioning and stable clamping can greatly reduce the scrap caused by clamping deviation.

[0028] To facilitate drilling at multiple points, the present invention employs a transverse component 6, which includes a square frame 601 bolted to a fixed frame 2. An I-shaped slider 602 is slidably connected inside the square frame 601. A threaded rod 603 is rotatably connected between the inner walls of the two sides of the square frame 601 via bearings. A second drive motor 604, which causes the threaded rod 603 to rotate forward and backward along the axial direction, is bolted to one outer wall of the square frame 601. After clamping the steel template, the second drive motor 604 is started to rotate the threaded rod 603. During its rotation, the I-shaped slider 602 moves laterally along the inner wall of the square frame 601. The transverse component 6 drives the drilling component 7 to move laterally, enabling multi-hole processing of the entire transverse range of the steel template in a single clamping operation, reducing the auxiliary time for disassembling and reassembling the steel template.

[0029] The further drilling assembly 7 includes a second cylinder 701 bolted to the upper surface of the I-shaped slider 602. The output end of the second cylinder 701 passes through the lower surface of the I-shaped slider 602 and is bolted to a connecting frame 702. A third drive motor 703 is bolted to the bottom inner wall of the connecting frame 702. The output end of the third drive motor 703 passes through the bottom wall of the connecting frame 702 and is keyed to a drill head 704. After the I-shaped slider 602 moves to the position where drilling is required, the third drive motor 703 is started to drive the drill head 704 to rotate at high speed. Then, the second cylinder 701 is started to extend, causing the drill head 704 to move downward, thereby performing drilling operations on the steel template. When drilling is required at different positions, the drill head 704 is moved upward to change the position of the I-shaped slider 602 to the position where drilling is required, and then the above operation is repeated.

[0030] To facilitate the feeding and unloading of steel formwork, the present invention employs a conveying assembly 8, which includes a first horizontal plate 801 bolted to the middle position between the inner walls of both sides of the base frame 1. Second horizontal plates 802 are bolted to both sides of the inner walls of the base frame 1, located on either side of the first horizontal plate 801. Two round rods 803 are slidably connected through each of the two second horizontal plates 802. A connecting frame 804 is bolted to the top of the multiple round rods 803. Support columns 805 are bolted to the four corners of the upper surface of the connecting frame 804. A conveyor belt 806 is bolted to the top of the multiple support columns 805. The lower surface of the first horizontal plate 801 is connected to... The bolted connection includes a cylinder 807 that moves the connecting frame 804 up and down. When drilling holes in the steel template, the template is first placed on the conveyor belt 806 for transport. When the template is transported to the middle of the conveyor belt 806, the cylinder 807 is activated to extend, thereby moving the conveyor belt 806 upward through the connecting frame 804 until the template is delivered above the side clamping assembly 3. The conveying assembly 8 automatically completes the loading and unloading of the steel template, reducing manual operation time and avoiding equipment waiting time caused by slow manual loading and unloading. This achieves automated production process and effectively improves production efficiency.

[0031] After drilling is completed, start the drive motor 306 to reverse so that the two side clamps 304 move away from each other. After the side clamps 304 and the L-shaped lower clamp 502 are no longer in contact, start the cylinder 807 to extend so that the conveyor belt 806 moves upward. After the conveyor belt 806 moves upward and contacts the steel template, it continues to move upward to lift the steel template. Then the conveyor belt 806 can send the steel template out.

[0032] It should be noted that: drive motor 306, cylinder 402, drive motor 604, cylinder 701, drive motor 703 and cylinder 807 are all existing technologies. Those skilled in the art can set them according to actual needs, which will not be elaborated here.

[0033] In this application, an annular groove is provided axially on the inner wall of the threaded hole, and a nylon 66 damping ring with a Shore hardness of 85A is embedded in the groove. The continuous axial clamping force generated by its elastic deformation forms a helical angle interference fit of 15°-20° with the surfaces of the threaded rod 603 and the double-acting screw 305. When the threaded pair is subjected to axial vibration load, the nylon insert can generate a maximum elastic compression of 0.3mm, which increases the friction coefficient between the thread contact surfaces from 0.15 to 0.68 (tested according to ASTM D1894 standard), effectively suppressing loosening displacement caused by thread springback.

[0034] The present invention is used in the following steps: S1: When it is necessary to drill holes in the steel template, first place the steel template on the conveyor belt 806 for conveying. When the steel template is conveyed to the middle position of the conveyor belt 806, start the cylinder 3 807 to extend and then move the conveyor belt 806 upward through the connecting frame 804 until the steel template is sent above the side clamping assembly 3. S2: When the steel template is sent to the side clamping assembly 3, the drive motor 306 is started to drive the bidirectional lead screw 305 to rotate. During its rotation, the two slides 302 are driven to move closer to each other along the slide rod 301, and then the pre-clamping assembly 5 is driven to move closer to each other through the side clamping plate 304. S3: After the pre-clamping assembly 5 moves to a position where it can catch the steel template, turn off the drive motor 306 and start the cylinder 807 to retract, causing the conveyor belt 806 to move down and thus the steel template to move down. During the process of the steel template moving down, it will be caught by the L-shaped lower clamping plate 502 in the pre-clamping assembly 5. Continue to retract the cylinder 807 to move the conveyor belt 806 to the bottom. Then start the drive motor 306 again to move the side clamping plate 304. When the two sides of the steel template are in contact with the two L-shaped lower clamping plates 502 respectively, the continued movement will compress the spring 504 to retract. When the L-shaped lower clamping plate 502 and the side clamping plate 304 are in close contact, the clamping operation on both sides of the steel template is completed. S4: After clamping both sides of the steel template, start cylinder 402 to extend, thereby driving the L-shaped upper clamping plate 403 at its end to move downward. After it comes into close contact with the steel template, the upper surface of the steel template can be tightly clamped. S5: After the clamping operation of the steel template is completed, start the drive motor 604 to make the threaded rod 603 rotate. During its rotation, it will drive the I-shaped slider 602 to move laterally along the inner wall of the frame 601. S6: After the I-shaped slider 602 moves to the position where drilling is required, start the drive motor 703 to drive the drill head 704 to rotate at high speed. Then start the cylinder 701 to extend and move the drill head 704 downward to drill the steel template. When drilling is required at different positions, move the drill head 704 upward to change the position of the I-shaped slider 602 to the position where drilling is required, and then repeat the above operation. S7: After drilling is completed, start the drive motor 306 to reverse so that the two side clamps 304 are far apart. After the side clamps 304 are out of contact with the L-shaped lower clamp 502, start the cylinder 807 to extend so that the conveyor belt 806 moves upward. After the conveyor belt 806 moves upward and contacts the steel template, it continues to move upward to lift the steel template. Then the conveyor belt 806 can send the steel template out.

[0035] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
