Abstract
Description
Technical Field
[0001] This utility model relates to the field of water conservancy construction equipment technology, and more specifically, to an automatic grouting device for repairing cracks in reservoir dams. Background Technology
[0002] A dam is a dike or weir that impounds water from a river, such as a reservoir or a levee. Dams bear enormous water pressure, especially when water levels rise or there is a sudden flood. The increased water pressure can cause uneven stress distribution and stress concentration in the dam structure, eventually leading to cracks. When cracks appear in a dam, grouting equipment is used to fill the cracks and enhance the dam's strength and stability.
[0003] Based on the above, the inventors have discovered that traditional grouting equipment generally requires manual operation by workers. If the crack is high, it is not easy to grout and repair the crack, requiring workers to climb to the crack location to perform the grouting work, which reduces worker safety. In addition, traditional grouting equipment generally does not have a buffer function at the grouting head, making it difficult to buffer the pressure of the grout. When the grout pressure increases sharply, it is easy to cause leakage at the grouting head, resulting in grout waste. Therefore, in view of this, the inventors have studied and improved the existing structure to provide an automatic grouting device for repairing cracks in reservoir dams, aiming to achieve a more practical purpose. Utility Model Content
[0004] 1. Technical problems to be solved
[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide an automatic grouting device for repairing cracks in reservoir dams. It can utilize a climbing cylinder in conjunction with upper and lower braking mechanisms to allow the upper and lower sliders to alternately climb upwards on the climbing track, thereby driving the grouting head to move upwards to facilitate grouting repair of cracks at higher locations. This ensures overall operational safety while improving grouting efficiency. In addition, a buffer seat is added at the grouting head to provide a buffering function, solving the problem of leakage at the grouting head when the grout pressure increases sharply, and avoiding waste of grout material.
[0006] 2. Technical Solution
[0007] To solve the above problems, the present invention adopts the following technical solution.
[0008] An automatic grouting device for repairing cracks in a reservoir dam includes a mounting frame. A grout storage tank is mounted at one end of the mounting frame, and a climbing rail is mounted on one side of the mounting frame. An upper slider and a lower slider are slidably connected to the outer periphery of the climbing rail. Climbing cylinders are fixedly mounted between both ends of the upper slider and the lower slider. An upper braking mechanism and a lower braking mechanism are respectively mounted on the sides of the upper slider and the lower slider near the mounting frame. A linear module is fixedly mounted at one end of the upper slider. A buffer seat is mounted on the movable seat of the linear module. A grouting head is horizontally mounted on the buffer seat. A grouting pump is mounted in the middle of the mounting frame. The inlet end of the grouting pump is connected to the inside of the grout storage tank through a pipe, and the outlet end of the grouting pump is connected to the grouting head through a pipe.
[0009] Furthermore, the upper braking mechanism and the lower braking mechanism have the same structure. The upper braking mechanism includes a brake cylinder fixedly installed on the side of the upper slider near the mounting frame. The output end of the brake cylinder extends to the inner side of the upper slider and is fixedly connected to a brake plate. One side of the brake plate abuts against the outer side of the climbing track.
[0010] Furthermore, the buffer seat includes a fixed seat bolted to the top of the movable seat of the linear module. Buffer rubber pads are provided between the bottom two ends of the fixed seat and the top of the movable seat of the linear module. An elastic steel sheet is provided between the bottom middle of the fixed seat and the top of the movable seat of the linear module. The grouting head is fixedly installed on the fixed seat.
[0011] Furthermore, a stirrer is installed inside the slurry storage tank, and a feed hopper is fixed and connected to the upper part of the slurry storage tank.
[0012] Furthermore, a handle is fixedly connected to the other end of the mounting bracket.
[0013] Furthermore, the mounting bracket is equipped with a traveling wheel and a universal wheel with a braking function at both ends of its bottom.
[0014] 3. Beneficial effects
[0015] Compared with existing technologies, the advantages of this utility model are:
[0016] (1) In this scheme, the climbing cylinder is combined with the upper and lower braking mechanism so that the upper and lower sliders can alternately climb up or down on the climbing track, thereby driving the grouting head to move up or down, so as to grout and repair cracks at different heights. This ensures the overall operational safety and improves the efficiency of grouting.
[0017] (2) In this scheme, by adding a buffer seat at the grouting head, when the grouting pressure at the grouting head increases sharply, the rubber buffer pad and the elastic steel sheet have excellent elasticity and resilience, and absorb the impact energy through their own elastic deformation, so that the grouting head is effectively buffered, avoiding the phenomenon of grout leakage at the grouting head due to the sudden increase in grout pressure, and reducing the waste of grout material.

[0041] Example:
[0042] Please see Figures 1-4 An automatic grouting device for repairing cracks in a reservoir dam includes a mounting frame 1. A grout storage tank 2 is mounted at one end of the mounting frame 1. A climbing track 3 is mounted on one side of the mounting frame 1. An upper slider 4 and a lower slider 5 are slidably connected to the outer periphery of the climbing track 3. Climbing cylinders 6 are fixedly mounted between both ends of the upper slider 4 and the lower slider 5. An upper braking mechanism 7 and a lower braking mechanism 8 are respectively mounted on the side of the upper slider 4 and the lower slider 5 near the mounting frame 1. A linear module 9 is fixedly mounted at one end of the upper slider 4. A buffer seat 10 is mounted on the moving seat of the linear module 9. A grouting head 11 is horizontally mounted on the buffer seat 10. A grouting pump 12 is mounted in the middle of the mounting frame 1. The inlet end of the grouting pump 12 is connected to the inside of the grout storage tank 2 through a pipe, and the outlet end of the grouting pump 12 is connected to the grouting head 11 through a pipe.
[0043] See Figure 3 The upper braking mechanism 7 and the lower braking mechanism 8 have the same structure. The upper braking mechanism 7 includes a brake cylinder 701 fixedly installed on the side of the upper slider 4 near the mounting frame 1. The output end of the brake cylinder 701 extends to the inner side of the upper slider 4 and is fixedly connected to a brake plate 702. One side of the brake plate 702 abuts against the outer side of the climbing track 3.
[0044] See Figure 4 The buffer seat 10 includes a fixed seat 1001 bolted to the top of the movable seat of the linear module 9. Buffer rubber pads 1002 are provided between the bottom two ends of the fixed seat 1001 and the top of the movable seat of the linear module 9. An elastic steel sheet 1003 is provided between the bottom middle of the fixed seat 1001 and the top of the movable seat of the linear module 9. The grouting head 11 is fixedly installed on the fixed seat 1001.
[0045] See Figure 1 A stirrer 13 is installed inside the slurry storage tank 2, and a feed hopper 14 is fixed and connected to the upper part of the slurry storage tank 2.
[0046] See Figure 2 The other end of the mounting bracket 1 is fixedly connected to a handle 15.
[0047] See Figure 2 The bottom ends of the mounting bracket 1 are respectively equipped with a traveling wheel 16 and a universal wheel 17 with a braking function.
[0048] In use: When grouting repair is required for cracks at higher points of the dam body, the lower slider 5 is fixed on the climbing track 3 using the lower braking mechanism 8. Then, the climbing cylinder 6 is activated, and the output end of the climbing cylinder 6 pushes the upper slider 4 upward, causing it to move the grouting head 11 upward. Next, the upper slider 4 is fixed on the climbing track 3 using the upper braking mechanism 7. Then, the brake on the lower slider 5 is released, and the climbing cylinder 6 is activated again to drag the lower slider 5 upward, causing it to move upward. The above operation is repeated so that the upper slider 4 and the lower slider 5 climb upward alternately until the grouting head 11 reaches the designated position. Finally, the linear module 9 is used to move one end of the grouting head 11 into the crack for grouting. The whole operation is convenient and quick, ensuring the overall safety of the operation while improving the efficiency of grouting.
[0049] In addition, the buffer rubber pad 1002 and the elastic steel sheet 1003 have excellent elasticity and resilience, and absorb impact energy through their own elastic deformation, so that they are effectively buffered during the grouting process of the grouting head 11, avoiding the phenomenon of grout leakage at the grouting head 11 due to a sudden increase in grout pressure, and reducing the waste of grout material.
