Description

Technical Field

[0001] The utility model belongs to the technical field of bridge construction, in particular to a drilling platform used for highway bridge construction. Background Art

[0002] The drilling platform for highway bridge construction is mainly used for construction operations such as bored piles, and is a key part of the foundation construction of water bridges. Drilling platforms are usually divided into two categories: fixed and floating.

[0003] The patent with the publication number CN214365869U in the traditional design discloses a highway bridge construction drilling platform, including a drilling platform body, a locking rod is connected to the inner thread of the side rod, a connection groove is provided on the outer wall of the middle part of the drill bit, a slurry suction block is movably connected to the outer wall of the connection groove, a water pump is fixedly connected to the right side of the drilling platform body, a liquid outlet pipe is provided on the top of the water pump, a liquid inlet pipe is provided on the bottom of the water pump, a plurality of liquid inlet holes are provided on the outer wall of the slurry suction block, a shock-absorbing spring is fixedly connected to the inner wall of the shock-absorbing ring, and a contact block is fixedly connected to the end of the shock-absorbing spring away from the inner wall of the shock-absorbing ring. The above device is provided with a connection groove on the outer wall of the middle part of the drill bit, a slurry suction block is movably connected to the outer wall of the connection groove, and the end of the liquid inlet pipe away from the water pump is fixedly connected to the slurry suction block. The mud generated during the drilling process is sucked into the liquid outlet pipe by the water pump, thereby improving the drilling efficiency.

[0004] However, there are some problems with traditional technologies: Traditional highway bridge construction drilling platforms are usually designed to be fixed, which limits their flexibility in multi-point drilling operations. In the actual construction process, workers need to constantly determine the precise location of the next hole based on the location of the previous hole, and manually move or adjust the drilling platform to the new location. This cumbersome operation is not only time-consuming and labor-intensive, but may also cause positioning errors due to human factors, thus affecting construction quality;

[0005] In a specific highway bridge construction project, engineers plan to perform multiple drilling operations along the bridge axis to detect foundation conditions. Since the drilling platform is fixed, workers need to first determine the first drilling position according to the design drawings and drill. After completion, workers need to manually move the drilling platform to the next predetermined position and use measuring tools to ensure the accuracy of the new position. This process is repeated between multiple drilling points, which not only leads to slow construction progress, but also increases the risk of drilling position error due to the instability of manual operation. Therefore, we propose a drilling platform for highway bridge construction. Utility Model Content

[0024] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0025] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0026] like Figures 1 to 5 As shown, an embodiment of the utility model provides a drilling platform for highway bridge construction, including a load-bearing vehicle 1, a drilling assembly 2 is fixedly installed at the rear of the load-bearing vehicle 1, two elastic telescopic rods 4 are fixedly installed on both sides of the load-bearing vehicle 1, a fixed plate 5 is rotatably installed on the output end of one of the elastic telescopic rods 4 on one side, and a slide plate 6 is rotatably installed on the output end of the other elastic telescopic rod 4 on one side, the outside of the slide plate 6 is slidably connected to the fixed plate 5, two first electric push rods 7 are fixedly installed on the lower part of the fixed plate 5, and the lower parts of the two first electric push rods 7 are fixedly connected to a guide plate 8, and a plurality of infrared rangefinders 3 for ranging are also fixedly installed on the upper part of the load-bearing vehicle 1, the infrared rangefinder 3 is electrically connected to the load-bearing vehicle 1, and the infrared rangefinder 3 is coaxially arranged with the elastic telescopic rod 4.

[0027] The above-mentioned drilling platform for highway bridge construction, the control system is integrated on the carrier vehicle 1, responsible for receiving the data of the infrared rangefinder 3, and performing corresponding control according to the data. The control system can control the extension and contraction of the electric push rod, the moving direction and speed of the carrier vehicle 1, and the start and stop of the drilling assembly 2. When the carrier vehicle 1 is started, the first electric push rod 7 is first controlled by the carrier vehicle 1 control system to descend, so that the guide plate 8 gradually approaches the edge of the highway bridge. Through the precise control of the first electric push rod 7, the guide plate 8 finally contacts the edge of the highway bridge. After the guide plate 8 contacts the edge of the highway bridge, the fixed plate 5, the slide plate 6 and the two elastic telescopic rods 4 start to work together. The control system will calculate the bending angle of the guide plate 8 according to the telescopic distance of the elastic telescopic rod 4 measured by the two infrared rangefinders 3, so as to determine whether the carrier vehicle 1 is traveling parallel to the edge of the highway bridge, and then realize the angle adjustment of the travel direction of the carrier vehicle 1. After the angle adjustment is completed, the control system will continue to monitor the distance between the guide plate 8 and the edge of the highway bridge using the infrared rangefinder 3. By comparing the data of the two infrared rangefinders 3, the control system can accurately control the movement of the carrier vehicle 1 so that it maintains a specified distance from the edge of the highway bridge. When the carrier vehicle 1 moves to the specified position, the control system will start the drilling assembly 2 to perform the drilling operation. During the drilling process, the control system will continue to monitor the data of the infrared rangefinder 3 and adjust the position and angle of the carrier vehicle 1 as needed to maintain the accuracy of the drilling. After completing a drilling point, the control system will automatically record the current position and angle information and plan the path to the next drilling point. The carrier vehicle 1 will automatically move to the next drilling point according to the planned path, and repeat the above steps for continuous drilling operations. In this way, construction efficiency can be greatly improved and manual intervention and errors can be reduced.

[0028] In this embodiment, the carrier vehicle 1 includes a vehicle body 101, and support frames 102 are fixedly installed on both sides of the vehicle body 101, and gears 105 are rotatably installed inside each of the two sides of each support frame 102. The support frame 102 is provided with tracks 104 through the outer sleeve of the gear 105, and the two gears 105 are meshed and connected with the tracks 104. A drive motor 103 is fixedly installed on one side of the support frame 102, and the output end of the drive motor 103 is fixedly connected to the gear 105.

[0029] When the carrier vehicle 1 needs to be moved, the control system starts the drive motor 103, and the drive motor 103 starts to rotate. Its output end drives the gear 105 fixedly connected thereto to rotate. Since the crawler 104 is meshed and connected with the two gears 105, when one gear 105 rotates driven by the drive motor 103, the other gear 105 will also rotate due to the meshing action of the crawler 104. In this way, the two gears 105 rotate at the same time, driving the crawler 104 to move forward or backward. As the crawler 104 moves, the carrier vehicle 1 also moves forward or backward accordingly, which is suitable for occasions such as highway bridge construction that require flexible movement and stable operation. By accurately controlling the rotation direction and speed of the drive motor 103, the precise movement and positioning of the carrier vehicle 1 can be achieved, providing a stable and reliable platform for operations such as drilling.

[0030] In this embodiment, the elastic telescopic rod 4 includes a fixed tube 401, which is fixed to one side of the carrier vehicle 1. A sliding rod 402 is slidably installed inside the fixed tube 401, and a slider 403 is fixedly connected to the outside of the sliding rod 402. One side of the slider 403 is fixedly connected to the inner wall of the fixed tube 401 through a spring 404.

[0031] The infrared rangefinder 3 is installed on the upper part of the carrier vehicle 1, and is coaxially arranged with the elastic telescopic rod 4 or near it to ensure that the moving trajectory of the slide bar 402 can be accurately detected. The infrared rangefinder 3 measures the distance by emitting infrared light and receiving the reflected light. The reflective surface installed on the slide bar 402 can increase the reflection area of ​​the infrared light and improve the distance measurement accuracy. The infrared rangefinder 3 is connected to the control system, and the control system calculates the moving trajectory and telescopic distance of the slide bar 402 in real time according to the data of the rangefinder. The control system can monitor the moving trajectory and telescopic distance of the slide bar 402 in real time and adjust the driving angle of the carrier vehicle 1.

[0032] In this embodiment, the drilling assembly 2 includes a second electric push rod 201, which is fixedly mounted at the rear of the carrier 1, and a support seat 202 is fixedly mounted at the output end of the second electric push rod 201, and the support seat 202 is slidably mounted at the rear of the carrier 1. The four corners of the upper part of the support seat 202 are respectively fixedly mounted with a third electric push rod 203, and the output end of the third electric push rod 203 is fixedly connected to a lifting platform 204, and a drilling motor 205 is fixedly mounted at the lower part of the lifting platform 204 through the support seat and the carrier 1, and a drill rod 206 is fixedly connected to the output end of the drilling motor 205.

[0033] The second electric push rod 201 is fixedly mounted on the rear of the carrier 1. By controlling the extension and retraction of the second electric push rod 201, the lateral position of the entire drilling assembly 2 on the carrier 1 can be adjusted. This step allows the user to perform lateral fine adjustment of the drilling assembly 2 according to the position of the carrier 1 and the actual situation of the highway bridge to ensure that the drill rod 206 can accurately align with the drilling point;

[0034] The support seat 202 is slidably mounted at the rear of the carrier vehicle 1 and is fixedly mounted by the output end of the second electric push rod 201. When the second electric push rod 201 is extended or retracted, the support seat 202 will move accordingly, driving the entire drilling assembly 2 to move laterally. By accurately controlling the extension amount of the second electric push rod 201, the precise position adjustment of the drilling assembly 2 can be achieved; the third electric push rod 203 is mounted at the upper four corners of the support seat 202 and is used to adjust the height of the lifting platform 204. Before drilling, the user can adjust the extension amount of the third electric push rod 203 as needed to make the lifting platform 204 at a suitable height to ensure that the drill rod 206 can be smoothly aligned with the drilling point;

[0035] The lifting platform 204 is fixedly connected by the output end of the third electric push rod 203, carrying the drilling motor 205 and the drill rod 206. The design of the lifting platform 204 allows the drill rod 206 to be lifted in the vertical direction to meet the drilling requirements of different heights; the drilling motor 205 is fixedly installed at the bottom of the lifting platform 204, and its output end is fixedly connected to the drill rod 206. In the preparation stage, the drilling motor 205 is in a standby state, waiting for the instruction to start drilling; when the drilling assembly 2 is adjusted to a suitable position, the control system will issue an instruction to drive the third electric push rod 203 to shrink and make the lifting platform 204 descend. As the lifting platform 204 descends, the drilling motor 205 and the drill rod 206 will also descend until the tip of the drill rod 206 contacts the drilling point. Once the drill rod 206 contacts the drilling point, the drilling motor 205 will start working, drive the drill rod 206 to rotate and feed, and perform the drilling operation. The control system will monitor the drilling process in real time to ensure that the drill rod 206 operates according to the preset parameters.

[0036] The working principle of this utility model:

[0037] When in use, the control system of the carrier vehicle 1 controls the first electric push rod 7 to descend, so that the guide plate 8 gradually approaches the edge of the highway bridge. Through the precise control of the first electric push rod 7, the guide plate 8 finally contacts the edge of the highway bridge. After the guide plate 8 contacts the edge of the highway bridge, the fixed plate 5, the slide plate 6 and the two elastic telescopic rods 4 start to work together. The control system will calculate the bending angle of the guide plate 8 according to the telescopic distance of the elastic telescopic rod 4 measured by the two infrared rangefinders 3, so as to determine whether the carrier vehicle 1 is traveling parallel to the edge of the highway bridge, and then realize the angle adjustment of the travel direction of the carrier vehicle 1. After the angle adjustment is completed, the control system will continue to monitor the distance between the guide plate 8 and the edge of the highway bridge using the infrared rangefinder 3. By comparing the data of the two infrared rangefinders 3, the control system can accurately control the movement of the carrier vehicle 1 so that it maintains a specified distance from the edge of the highway bridge. When the carrier vehicle 1 moves to the specified position, the control system will start the drilling assembly 2 to perform the drilling operation. During the drilling process, the control system will continue to monitor the data of the infrared rangefinder 3 and adjust the position and angle of the carrier vehicle 1 as needed to maintain the accuracy of the drilling. After completing a drilling point, the control system will automatically record the current position and angle information and plan the path to the next drilling point. The carrier vehicle 1 will automatically move to the next drilling point according to the planned path and repeat the above steps for continuous drilling operations. In this way, the construction efficiency can be greatly improved and manual intervention and errors can be reduced.
