Abstract
Description
Technical Field
[0001] This application belongs to the technical field of dam construction trolleys, specifically a mobile drilling and grouting integrated construction platform vehicle. Background Technology
[0002] In dam foundation construction, the consolidation of the toe slab, curtain drilling, and grouting of rockfill dams are crucial for ensuring dam stability. Currently, the industry generally uses construction trolleys for these tasks, and their application process and existing technologies are as follows:
[0003] The dam's toe slab has a unique structure. The left bank is divided into two sections with elevations of 1048m-1089m and 1089m-1140m, while the right bank is also divided into one section with an elevation of 1048m-1140m. The toe slab slope is approximately 30°. The left bank has a sloping length of 190.3m, the right bank 143.0m, and the width 4.0m. During construction, the trolley beams and columns were first cut into sections at the camp and transported to the site for assembly. Four three-span beam units were fabricated to determine the slope and allow for adjustments. The columns were connected with crossbeams (the top was not connected to the crossbeams to avoid obstructing the holes). Then, wooden planks and timber were laid, canopies and other auxiliary components were erected, and equipment was hoisted to complete the main body of the trolley. Finally, the trolley was moved up and down along the toe slab slope using a traction system.
[0004] However, in practical applications, the existing construction trolleys have poor adaptability between the bracket at the bottom of the trolley body and the toe plate angle. When facing toe plates with different slopes, it is difficult to flexibly adjust the bracket angle, resulting in insufficient adaptability. This limits the reusability of the trolley in complex terrain and toe plate construction scenarios with different slopes. For example, in toe plate areas with slight differences in slope or local undulations in the terrain, the bracket cannot accurately fit the slope surface. This not only affects the stability of the trolley during construction, leading to a decrease in the accuracy of drilling and grouting operations, increasing construction errors and quality risks, but also requires additional modifications or re-fabrication of the bracket when the trolley is used for construction on toe plates with different slopes due to adaptability issues. This consumes manpower, material resources, and time costs, reducing construction efficiency. Therefore, a mobile drilling and grouting integrated construction platform vehicle is provided.

It also strengthens the support rod and the plug-in structure to improve stability, allowing the platform vehicle to flexibly cope with toe plate construction on different slopes, greatly improving the efficiency and accuracy of drilling and grouting operations, and reducing construction safety risks.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0021] refer to Figures 1-4As shown, the mobile drilling and grouting integrated construction platform vehicle includes a construction platform 1. Multiple reinforcing supports 12 are fixedly installed on the inner wall of the construction platform 1. Multiple footboards 7 are fixedly installed on the top surface of the construction platform 1 via bolts. A canopy 8 is fixedly installed on the top surface of the footboards 7. The reinforcing supports 12 enhance the structural strength and overall stability of the construction platform 1, distribute the loads generated by the drilling rig and personnel during construction, prevent platform deformation, and ensure construction safety. The construction platform 1 is located on the toe slab of the rockfill dam. The footboards 7 provide a safe and convenient working surface for construction personnel. Drilling rigs and grouting machines are installed on the footboards 7 to facilitate subsequent drilling and grouting operations at the construction site. The canopy 8 effectively shields against rain and sunlight, creating a relatively comfortable working environment for construction personnel and protecting equipment and tools on the platform from severe weather.
[0022] refer to Figures 1-4 As shown, the bottom surface of the construction platform 1 is equipped with a bottom support 2. Two support columns 1 3 are fixedly installed on the bottom surface of the construction platform 1 by bolts. Adjustable support rods 4 are movably fitted inside the two support columns 1 3. The bottom end of the adjustable support rod 4 is hinged to the top surface of the bottom support 2. Two support columns 2 5 are fixedly installed on the bottom surface of the construction platform 1. The bottom end of the two support columns 2 5 is hinged to the top surface of the bottom support 2. Positioning protrusions 9 are fixedly installed at the top of the support columns 1 3 and support columns 2 5. The bottom surface of the construction platform 1 has grooves that match the positioning protrusions 9. The top end of the positioning protrusions 9 is inserted into the groove. The bottom support 2 provides basic support for the entire platform vehicle and adapts to the slope shape of the toe plate. The support columns 1 3, support columns 2 5 and adjustable support rods 4 work together to form a stable support system. The insertion structure of the positioning protrusions 9 and the groove can quickly and accurately realize the connection and positioning of the columns and the platform, improve assembly efficiency and structural connection stability, and ensure the overall stability of the platform vehicle when working on the slope.
[0023] refer to Figures 1-4As shown, an angle adjustment assembly 6 connected to the adjusting rod 4 is provided on one side of the support column 3. The angle adjustment assembly 6 includes a connecting housing 601, a main drive shaft 602, a drive gear 603, a rack 604, a large gear 605, a motor 606, and a small gear 607. The connecting housing 601 is fixedly installed on the front side of the support column 3. The main drive shaft 602 is rotatably connected to the inside of the connecting housing 601 through a bearing. Two drive gears 603 are fixedly installed on the outer surface of the main drive shaft 602. The outer surface of the drive gears 603 extends into the interior of the support column 3. A rack 604 is embedded and fixedly installed on the front side of the adjusting rod 4. The drive gears 603 and the rack 604 mesh with each other. Next, a large gear 605 is fixedly installed on the outer surface of the main drive shaft 602 near the middle, and a motor 606 is fixedly installed on the bottom surface of the connecting housing 601. A small gear 607 is fixedly installed on the drive end of the motor 606, and the small gear 607 meshes with the large gear 605. Through the set angle adjustment component 6, the extension and retraction of the adjustment rod 4 can be realized by the motor 606, through the transmission of the small gear 607, the large gear 605, the main drive shaft 602, the drive gear 603 and the rack 604, thereby flexibly adjusting the angle of the bottom support 2, so that the platform vehicle can adapt to toe plates with different slopes, improve the reusability and adaptability of the equipment in complex terrain construction scenarios, and ensure the accuracy and stability of drilling and grouting operations.
[0024] refer to Figures 1-4 As shown, a U-shaped limiting plate 10 is fixedly installed on the bottom surface of the bottom support 2. A fixing protrusion 11 is provided inside the U-shaped limiting plate 10. Steel wire rope hanging rings 13 are fixedly installed on the front and rear sides of the bottom support 2. The bottom of the fixing protrusion 11 is fixed to the top surface of the toe plate. By cooperating with the U-shaped limiting plate 10 and the fixing protrusion 11, the movement of the platform vehicle on the toe plate can be limited and guided, preventing the platform vehicle from deviating laterally during operation or movement, and enhancing the stability and safety of the platform vehicle when moving along the slope of the toe plate. The steel wire rope hanging rings 13 facilitate the connection with the steel wire rope of the traction system, providing a reliable connection point for the platform vehicle to move up and down along the slope of the toe plate, ensuring the smoothness and safety of the traction movement process.
[0025] The implementation principle of the mobile drilling and grouting integrated construction platform vehicle embodiment of this application is as follows: The user first uses the U-shaped limiting plate 10 at the bottom of the bottom support 2 to cooperate with the fixed protrusion 11 on the toe plate to achieve initial positioning. Through the traction system, the steel wire rope hanging ring 13 connected to the bottom support 2 can drive the platform vehicle to move along the toe plate slope. When it is necessary to adapt to toe plates with different slopes, the motor 606 in the angle adjustment component 6 is activated. The motor 606 drives the small gear 607 to rotate, which in turn drives the large gear 605 to rotate, thereby causing the main drive shaft 602 to rotate. The drive gear 60 on the main drive shaft 602... 3 rotates accordingly, driving gear 603 meshes with rack 604 on adjusting support rod 4, realizing the extension and retraction of adjusting support rod 4 within support column 1 3, changing the angle of bottom bracket 2 to accurately fit the toe slope, and ensuring the stability of the platform structure through reinforcing support rod 12 on construction platform 1. Step 7 and canopy 8 provide working conditions for construction personnel. Support column 1 3 and support column 2 5 are connected to the groove of construction platform 1 through positioning protrusion 9 to form a stable support system, so that the platform vehicle can stably and flexibly carry out drilling and grouting operations on the toe slope, adapting to different construction conditions.
