Technical Field
[0001] This utility model relates to the field of drilling equipment technology, and in particular to a mobile metal drilling device for road and bridge construction. Background Technology
[0002] Road and bridge construction is the process of building roads and bridges, involving a series of complex and orderly operations. In road and bridge construction, metal drilling equipment is an indispensable tool with many important functions. During bridge construction, steel beams, steel columns and other components need to be drilled to achieve bolt connections to ensure structural stability. Precise drilling allows the connecting parts to fit tightly and withstand huge loads and complex stresses.
[0003] Currently, when drilling holes for bridges, drilling equipment is often used directly. However, due to the smoothness of the metal surface, slippage and drilling deviations are likely to occur during drilling, which requires improvement in operation. Utility Model Content
[0004] The purpose of this utility model is to solve the problem that in the existing technology, when drilling holes for bridges, drilling devices are often used directly, but due to the smooth surface of the metal, slippage and drilling deviation are likely to occur during drilling. Therefore, a movable metal drilling device for road and bridge construction is proposed.

The protective cover houses a motor, with a drill rod fixedly connected to the drive end of the motor.

An operating control cylinder moves the connecting block, the first cylinder, the positioning plate, and the second cylinder, allowing for precise adjustment of the drill rod and striking rod positions. The striking rod is used to impact the area to be drilled, effectively breaking internal stress in the metal and improving its structure. For high-hardness metal materials, such as high-strength steel used in bridge construction, this pre-treatment makes the subsequent drilling process smoother, preventing drill rod slippage, reducing drilling deviation, minimizing drill rod wear, improving drilling efficiency, extending drill rod lifespan, and reducing construction costs.

[0010] Preferably, there are two handles, which are arranged in a mirror image to facilitate normal use of the device.
[0011] Preferably, the longitudinal section of the mounting bracket is "n"-shaped, and the edges of the mounting bracket are rounded.
[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0013] In this invention, the operating control cylinder drives the connecting block, the first cylinder, the positioning plate, and the second cylinder to move, which can precisely adjust the position of the drill rod and the striking rod. The striking rod is used to impact the area to be drilled, which can effectively break the internal stress of the metal and improve the metal structure.

A motor 16 is used, with a drill rod 17 fixedly connected to its drive end. A positioning block 14 is slidably connected to the inner wall of the second cylinder 11, and a striking rod 20 is fixedly connected to the lower surface of the positioning block 14. The operating control cylinder 9 drives the connecting block 10, the first cylinder 12, the positioning plate 13, and the second cylinder 11 to move, which can precisely adjust the position of the drill rod 17 and the striking rod 20. The striking rod 20 is used to impact the area to be drilled, which can effectively break the internal stress of the metal and improve the metal structure. For metal materials with high hardness, such as high-strength steel used in bridge construction, the pre-treatment of the striking rod can make the subsequent drilling process smoother, avoid the drill rod 17 from slipping, reduce drilling deviation, reduce wear of the drill rod 17, improve drilling efficiency, extend the service life of the drill rod 17, and reduce construction costs.
[0024] Specifically, a control cylinder 9 is fixedly connected to the inner wall of the mounting hole 4, and a connecting block 10 is fixedly connected to the drive end of the control cylinder 9. The connecting block 10 is fixedly connected to the surface of the first cylinder 12. The operation of the control cylinder 9 can effectively adjust the position of the first cylinder 12 and the second cylinder 11.
[0025] In this embodiment: a first partition 19 is fixedly connected inside the first cylinder 12, one end of the drill rod 17 passes through the first partition 19, a first spring 18 is fixedly connected to the lower surface of the protective cover 15, and the lower end of the first spring 18 is fixedly connected to the upper surface of the first partition 19. The pressing cylinder 6 pushes the pressure plate 7 into the first cylinder 12, thereby pushing the protective cover 15, the motor 16 and the drill rod 17, so that the drill rod 17 performs drilling operations under stable pressure. During the drilling process, the stable pressure can prevent the drill rod 17 from shaking, ensure the verticality and accuracy of the drilling, improve the drilling quality, and avoid subsequent installation problems caused by drilling deviation.
[0026] In this embodiment: a second partition 22 is fixedly connected inside the second cylinder 11, one end of the striking rod 20 passes through the second partition 22, a second spring 21 is fixedly connected to the lower surface of the positioning block 14, and the lower end of the second spring 21 is fixedly connected to the upper surface of the second partition 22. The entire device has a simple operation process. Construction personnel only need to control the handle 3 to move the device, operate the control cylinder 9 to adjust the position, and control the pressing cylinder 6 and the motor 16 to drill holes. No complicated professional skills training is required to operate it, which enables more construction personnel to use the equipment proficiently, expands the scope of application for construction personnel, and improves the overall operation capability of the construction team.
[0027] Specifically, a handle 3 is fixedly connected to the upper surface of the mounting plate 1, and pulling the handle 3 can effectively move the device.
[0028] Specifically, there are two handles 3, which are set in a mirror image to facilitate normal use of the device.
[0029] Specifically, the longitudinal section of the mounting bracket 5 is "n" shaped, and the edges of the mounting bracket 5 are rounded.
[0030] Working principle: Construction workers can easily move the device to the drilling location on the road and bridge construction site by pushing handle 3. The mirror-like setting can adapt to pushing requirements in different directions, improving the flexibility of the device's movement.
[0031] Before drilling, the control cylinder 9 moves the connecting block 10, the first cylinder 12, the positioning plate 13, and the second cylinder 11. When the second cylinder 11 moves below the pressure plate 7, the control cylinder 9 is turned off. Then, the control cylinder 6 pushes the pressure plate 7 downward, and the pressure plate 7 is inserted into the second cylinder 11. The pressure plate 7 presses down on the positioning block 14 and the striking rod 20, causing the second spring 21 to deform under force. The striking rod 20 then impacts the area to be drilled. After the impact operation is completed, the control cylinder 6 moves the pressure plate 7 back to its original position, and the second spring 21 moves the positioning block 14 and the second cylinder 11 to its original position. The striking rod 20 is reset, and then the control cylinder 9 is operated to move the connecting block 10 and the first cylinder 12. When the first cylinder 12 moves below the pressure plate 7, the control cylinder 9 is turned off, and then the pressing cylinder 6 is controlled to push the pressure plate 7 downward. The pressure plate 7 is then inserted into the first cylinder 12. The pressure plate 7 pushes the protective cover 15, the motor 16, and the drill rod 17 downward. The motor 16 is energized, and the motor 16 drives the drill rod 17 to rotate. During the downward movement, the protective cover 15 compresses the first spring 18. After the drill rod 17 contacts the impact area, it can be quickly positioned and drilled.
[0032] After drilling is completed, the pressure cylinder 6 is controlled to reset the pressure plate 7, and the motor 16 is controlled to reverse the drill rod 17. The drill rod 17 then exits the hole, and under the action of the first spring 18, the protective cover 15, the motor 16 and the drill rod 17 are reset, ready for the next drilling operation.
