Description

Technical Field

[0001] The invention relates to the technical field of water conservancy projects, and in particular to an asphalt sealing and caulking device and method for dam body joints used in water conservancy construction. Background Art

[0002] In the construction of water conservancy projects, dams are important infrastructures. Their design and construction are not only related to the safety and durability of the project, but also directly affect the realization of functions in many aspects such as flood control, hydropower generation, and shipping. During the construction of the dam, the joints of the dam body are usually distributed at equal intervals. In some cases, in order to enhance the overall stability and anti-seepage performance of the dam, the joints may be designed to be more dense, while in other cases, in order to simplify the construction difficulty and reduce costs, the spacing between the joints may be relatively large. Since the sealing effect of the joints directly affects the overall anti-seepage performance and structural safety of the dam, asphalt is usually filled into the joints to achieve the sealing effect.

[0003] A patent application with reference publication number CN211922508U discloses an asphalt sealing and caulking device for dam body joints used in water conservancy construction. By placing a base frame on the dam body and adjusting the position of the support block up and down according to the slope of the dam body to change the angle between the support frame and the dam body, the effect of changeable caulking angle is achieved, making the sealing and caulking device more practical and convenient. After adjusting the caulking angle, the motor in the moving block drives the wheel to rotate in the slide groove, thereby pushing the moving block to move. During the movement of the moving block, the asphalt flows from the funnel through the caulking rod into the joint, so that the joint can be sealed quickly and accurately.

9. The asphalt sealing and caulking device for dam joints for water conservancy construction according to claim 8, characterized in that: A short shaft (7511) is rotatably provided at the lower right side of the cover body (757), a second rubber wheel (7512) is fixedly provided at the right end of the short shaft (7511), a stopper (7513) is fixedly provided at the top of the square vertical rod (756), a spring (7514) is sleeved on the outside of the square vertical rod (756), and the spring (7514) is fixedly connected between the top of the base plate (752) and the bottom of the stopper (7513), and the confluence pipe (754) is fixedly connected to the corresponding mechanical arm mechanism (6).

10. A method for asphalt sealing and caulking of joints in dam bodies for water conservancy construction, characterized in that: Using the asphalt sealing and caulking device for dam body joints for water conservancy construction as claimed in claim 5, the method comprises the following steps: Step 1: According to the spacing between two adjacent dam body joints, the position of the joint processing assembly (75) is adjusted in advance, and the second servo motor (79) is started to drive the adjusting rod assembly (73) to rotate. Under the drive of the adjusting rod assembly (73), except for the joint processing assembly (75) located in the middle, the remaining joint processing assemblies (75) slide along the limiting square rod (74) at the same time, so that the spacing between two adjacent joint processing assemblies (75) changes equally, until the spacing between two adjacent joint processing assemblies (75) is adjusted to be the same as the spacing between two adjacent dam body joints, that is, a plurality of joint processing assemblies (75) are respectively adjusted to be directly above the corresponding dam body joints; Step 2: Then turn off the second servo motor (79) to stop the adjustment rod assembly (73) from rotating, lock the positions of the plurality of seam processing assemblies (75), and then start the two mechanical arm mechanisms (6) at the same time, so that the first servo motors (64) in the two mechanical arm mechanisms (6) work at the same time, drive the screw rod (65) to rotate, and drive the caulking frame mechanism (7) to move along the surface of the dam body from the top of the dam body to the bottom of the dam body; Step 3: During the movement of the caulking frame mechanism (7), the joint processing assembly (75) cleans the joints of the dam body in time, and sweeps the impurities in the joints of the dam body toward the bottom of the dam body. At the same time, since the end of the main hose (77) away from the joint processing assembly (75) is connected to an asphalt tank filled with asphalt, the asphalt in the asphalt tank is sucked into each joint processing assembly (75) through the main hose (77) and each branch hose (76) under the action of the external pump body. At the same time, each joint processing assembly (75) fills the corresponding dam body joint that has been swept clean with asphalt to perform the caulking operation.
