[0027] This embodiment is written in a progressive manner.
[0028] Please Figures 1 to 5 As shown, this embodiment provides a drilling device for bridge construction. The device body 100 includes a base 110, a column 112, and a top plate 113. The top plate 113 and the base 110 are stably connected by the column 112, which supports the top plate 113. The bottom of the base 110 is equipped with casters 111, which increases the flexibility of movement. Whether it is a rapid transfer on a flat construction site or a fine adjustment of position on slightly undulating ground, the device can be easily achieved with the help of the casters 111, thereby significantly improving construction efficiency.
[0029] Looking at the top plate 113, a groove 114 is provided at its bottom end. The groove 114 is connected to the first lead screw 115 through a bearing. A motor 116 is firmly fixed on the outer wall of the top plate 113. The motor 116 serves as a drive source, and its output end is tightly connected to the first lead screw 115. When the motor 116 is powered on, it can efficiently convert electrical energy into mechanical energy, driving the first lead screw 115 to rotate. The first lead screw 115 is threadedly connected to the lead screw sleeve 117. Driven by the rotation of the first lead screw 115, the lead screw sleeve 117 can move smoothly left and right along the axial direction of the lead screw. The bottom end of the lead screw sleeve 117 is connected to the drilling assembly 118, which allows the drilling assembly 118 to flexibly adjust its drilling position as the lead screw sleeve 117 moves. Through this design, construction personnel can precisely control the horizontal position of the drilling assembly 118 according to different drilling requirements during bridge construction, achieving precise drilling operations on different parts of the bridge.
[0030] The drilling assembly 118 is the core component of the entire device to realize the drilling function. Its internal structure is ingeniously designed and consists of a hydraulic cylinder, a motor and a drill bit working together. The motor in the drilling assembly 118 provides high-speed rotation power to the drill bit and can accurately transmit its own high-speed rotation motion to the drill bit. The drill bit is made of high-strength and high-wear-resistant alloy material to ensure efficient and accurate drilling operations.
[0031] At the top of the base 110, a positioning fixture is provided, which consists of a positioning base 119, a first threaded rod 120 and a clamping plate 121. The positioning base 119 is threadedly connected to two first threaded rods 120. The two first threaded rods 120 are positioned opposite each other, and on the side where they are close to each other, they are connected to the clamping plate 121 through bearings.
[0032] When positioning workpieces of different sizes is required, the operator simply rotates the first threaded rod 120 by hand. Since the first threaded rod 120 is threadedly connected to the positioning base 119, its position on the positioning base 119 changes accordingly as the first threaded rod 120 rotates. This positional change is transmitted to the clamping plate 121 through the bearing, allowing the clamping plate 121 to move closer to or further away from the workpiece, thereby achieving stable clamping of workpieces of different sizes.
[0033] At the bottom of the positioning fixture, an adjustment mechanism is also provided, mainly composed of a mounting base 122, a second lead screw 123, and a movable block 124. The mounting base 122 is detachably connected to the top of the base 110. Inside the mounting base 122, the second lead screw 123 is mounted via a bearing, with one end extending out of the mounting base 122 and a handle fixed therefor easy operation. Construction personnel can easily control the rotation of the second lead screw 123 by manually turning this handle.
[0034] The movable block 124 is threadedly connected to the second lead screw 123. When the second lead screw 123 rotates under the drive of the handle, the movable block 124 moves back and forth along the axial direction of the second lead screw 123 according to the transmission principle of the thread. The top end of the movable block 124 is also firmly fixed to the bottom end of the positioning base 119. This allows the movable block 124 to move, driving the positioning base 119 and the workpiece placed on it to adjust their positions synchronously, further improving the flexibility and adaptability of the device in practical applications.
[0035] A support device is installed on the base 110. The support device consists of four independently telescopic support components. Each support component includes a threaded sleeve 125, a second threaded rod 126, and a support plate 127. The threaded sleeve 125 serves as the connecting part between the support component and the base 110, and is securely fixed to the base 110 to ensure stable transmission of support force during operation. The second threaded rod 126 is threadedly connected to the threaded sleeve 125, allowing the second threaded rod 126 to rotate and move smoothly within the threaded sleeve 125. The support plate 127 is connected to the bottom end of the second threaded rod 126 and its function is to directly contact the ground, providing a stable support surface for the device.
[0036] In actual bridge construction, the ground conditions at the construction site are often complex and varied, and may be uneven. To ensure the stability of the device under various ground conditions, each support component has the function of independently adjusting its support height. Construction workers can manually rotate the second threaded rod 126 using a specially equipped handle. As the second threaded rod 126 rotates, due to the threaded transmission relationship between it and the threaded sleeve 125, the second threaded rod 126 will move up and down within the threaded sleeve 125, thereby changing the height of the support plate 127 accordingly. By independently and precisely adjusting the support height of the four support components, even on uneven ground, the main body of the device 100 can be kept in a horizontal and stable state, providing a solid foundation for the smooth progress of drilling operations.
[0037] To further enhance the stability of the device during operation, anti-slip pads are specially installed at the bottom of the support plate 127. These anti-slip pads are made of high-friction rubber or other anti-slip materials, which can fit closely to the ground and effectively increase the friction between the support plate 127 and the ground.
[0038] At least one level 128 is installed on the top slab 113. As a high-precision measuring instrument, the level 128 can monitor the levelness of the top slab 113 in real time and provide feedback to construction personnel through a clear display. After the device is placed on the construction site, construction personnel can first observe the display data of the level 128 to determine whether the main body 100 of the device is level. If the device is found to be tilted, construction personnel can adjust the posture of the device gradually by adjusting the support height of the four support components in the support device according to the indication of the level 128, restoring it to a level state. This avoids problems such as drilling deviation and equipment damage caused by device tilting, providing important assurance for the quality and safety of bridge construction.
[0039] The main body 100 of this device is equipped with a complete and flexible power supply system, which mainly consists of a mains power interface, solar panels 129, and a storage battery. At bridge construction sites with mains power supply, the device can connect to an external mains power source via the mains power interface. Once mains power is connected, the device can directly utilize the mains power to power its operation, and can also store excess electrical energy in the storage battery through its built-in charging management system for later use.
[0040] Meanwhile, the solar panel 129, as a clean energy harvesting device, plays a crucial role in daylight conditions. The solar panel 129 converts solar energy into electrical energy and transmits it to a battery for storage via a dedicated circuit. This solar charging method is not only environmentally friendly and energy-saving but also reduces reliance on mains power, lowering construction costs. When the bridge construction site is in a remote area without mains power or when the mains power supply fails, the battery becomes the device's primary power source. The battery continuously provides a stable power output, ensuring the device operates normally under various complex construction environments and effectively guaranteeing the continuity and stability of bridge construction.
[0041] The mobile wheels 111 used in this device are shock-absorbing omnidirectional wheels and equipped with a reliable braking system. This design fully considers the actual needs of bridge construction sites, providing great convenience for the movement and positioning of the device. The omnidirectional wheels allow the device to move freely in all directions, easily facilitating straight-line travel, turning, and fine-tuning in confined spaces. This significantly improves the device's mobility on the construction site, enabling it to quickly reach designated drilling locations, reducing construction preparation time and increasing construction efficiency.
[0042] The shock absorption function of the mobile wheels 111 further enhances the stability of the device during movement. At bridge construction sites, the ground often contains various obstacles and uneven areas. When the device moves on such ground, the shock absorption function can effectively absorb and buffer the impact force caused by road bumps, thereby protecting the structural integrity of the device and the normal operation of its internal components.
[0043] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
