Description

Technical Field

[0001] This utility model relates to the field of construction grouting technology, and in particular to a grouting device for dam construction. Background Technology

[0002] A grouting device for dam construction is a specialized piece of equipment used in water conservancy engineering to inject cement grout, cement mortar, or other grouting materials under pressure into the gaps, cavities, and weak strata within the dam foundation or dam body. Its core function is to fill voids and reinforce rock or soil masses through grouting, thereby improving the dam's integrity, impermeability, and bearing capacity. Grouting devices for dam construction are indispensable core equipment in water conservancy projects, playing a crucial role in dam foundation treatment, dam body reinforcement, and seepage prevention and water stopping.

[0003] When using existing grouting equipment for dam construction, the process involves first surveying and designing, then debugging the equipment and preparing the grout. Next, boreholes are drilled and pipes are buried. Dilute grout is injected at low pressure to flush the boreholes, and then standard grout is injected at higher pressure. During the process, strategies are adjusted based on pressure and flow data. After construction is completed, the boreholes are sealed and the equipment is cleaned. The effect is then tested through a water pressure test. If the results are not up to standard, additional grouting is performed.

[0004] In existing technologies, some grouting devices used in dam construction suffer from reduced efficiency during operation. This is because the mud pumping pipe and mud discharge pipe are often connected by flanges, quick couplings, or threads. Flange connections require precise alignment of multiple bolt holes and even tightening of nuts. This necessitates multiple adjustments and slow operations during connection to ensure the continuity and stability of the mud pumping and discharge processes. Therefore, to address these shortcomings, a new grouting device for dam construction is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a grouting device for dam construction, which aims to improve the problem that some existing grouting devices for dam construction suffer from reduced work efficiency due to slow pipe connection during use.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A grouting device for dam construction includes a grouting pump. Pipes are fixedly connected to both the upper and lower ends of the grouting pump. A diaphragm accumulator is fixedly connected inside one of the pipes. A quick-release mechanism is slidably connected to the left end of the pipe. A mud inlet / outlet mechanism is slidably connected inside the quick-release mechanism. Two support frames are fixedly connected to the bottom side of the grouting pump. Support plates are fixedly connected inside the two support frames. A reinforcing mechanism is fixedly connected to the top side of the support plates. Both quick-release mechanisms include a connecting ring. The connecting ring is slidably connected to the outside of the pipe. Two connecting plates are fixedly connected to the right side of the connecting ring. A reset component is fixedly connected to the right side of the connecting plate. A transmission plate is fixedly connected to the left side of the connecting plate. Arc-shaped columns are slidably connected to both the upper and lower ends of the pipe. Limiting rings are slidably connected to the outside of the arc-shaped columns. A sealing ring is fixedly connected to the left side of the connecting ring.

[0008] The above scheme allows the grouting pump to transport slurry through pipes at both ends. The diaphragm accumulator inside the pipes can stabilize the pressure and buffer flow fluctuations. In the quick-release mechanism, the connecting ring can slide outside the pipe. Together with the reset component, transmission plate, arc column and limit ring, it can quickly connect and separate from the slurry inlet and outlet mechanism, which is convenient for equipment installation, disassembly and maintenance. The sealing ring ensures the sealing of the connection and prevents slurry leakage.

[0009] As a further description of the above technical solution:

[0010] The mud inlet / outlet mechanism includes a sliding ring, the outside of which is slidably connected to the inside of the pipe. A connecting ring is fixedly connected to the left end of the sliding ring, and a pipe body is fixedly connected to the left end of the connecting ring.

[0011] The above solution allows the sliding ring to slide flexibly within the pipe, achieving a sliding connection with the pipe and ensuring that the slurry inlet / outlet mechanism can be easily installed or disassembled with the pipe. The connecting ring fixed at the left end of the sliding ring is used to securely connect the pipe body. The combination of these three components allows the pipe body to be connected to the pipe through the sliding ring, enabling smooth entry and exit of slurry.

[0012] As a further description of the above technical solution:

[0013] The reinforcement mechanism includes a cylinder, the bottom of which is fixedly connected to the top of the support plate. An open plate is fixedly connected to the driving end of the cylinder. Rotating plates are rotatably connected to both the front and rear ends of the open plate. Sliding plates are rotatably connected to the far ends of the two rotating plates. An inclined plate is rotatably connected inside the sliding plate. Two sliding plates are rotatably connected to the outside of the inclined plate. Limit frames are slidably connected to the outside of the two sliding plates. A reinforcement plate is fixedly connected to the bottom of the two sliding plates.

[0014] The above scheme involves a cylinder fixed to the top side of the support plate, whose drive end moves the opening plate. The rotating plates at the front and rear ends of the opening plate rotate accordingly, which in turn moves the sliding plate. The inclined plate, which is rotatably connected inside the sliding plate, transmits force to the sliding plate as the sliding plate moves, causing the sliding plate to slide within the limit frame. This ultimately moves the reinforcing plate at the bottom. By extending and retracting the cylinder, the position and state of the reinforcing plate can be flexibly adjusted to ensure close contact with the ground or other supporting surfaces, thereby enhancing the stability of the entire grouting device during construction.

[0015] As a further description of the above technical solution:

[0016] Each of the reset components includes a connecting plate, the left side of which is fixedly connected to the right side of the connecting plate, and a spring is fixedly connected to the right side of the connecting plate.

[0017] The above solution involves a fixed connection between the left side of the connecting plate and the right side of the connecting plate, which transmits the movement of the connecting plate to the reset assembly. The spring connected to the right side deforms and stores elastic potential energy when the connecting plate slides along with the connecting plate. When the external force is removed, the spring releases the elastic potential energy to push the connecting plate, thereby resetting the connecting plate and ensuring that the quick-release mechanism can return to its initial state after connection or disassembly operations.

[0018] As a further description of the above technical solution:

[0019] The right ends of the two springs are fixedly connected to the inner walls of the upper and lower ends of the pipe, and the outer sides of the two connecting plates are slidably connected to the inner walls of the upper and lower ends of the pipe.

[0020] The above solution works as follows: when the connecting plate slides inside the pipe under external force, the spring is compressed to generate elastic deformation and accumulate energy. After the external force disappears, the spring releases elastic potential energy and pushes the connecting plate to slide back along the inner wall of the pipe, ensuring that the connecting ring and other components of the quick-release mechanism can return to their stable positions and maintaining the tightness and stability of the grouting device connection.

[0021] As a further description of the above technical solution:

[0022] The two arc-shaped columns have their adjacent ends slidably connected to the upper and lower ends of the sliding ring, respectively, and their distant ends are slidably connected to the adjacent ends of the two transmission plates.

[0023] The above scheme involves one end of the arc-shaped column sliding within the upper and lower ends of the sliding ring, and the other end sliding on the side of the transmission plate. When the transmission plate is subjected to force and moves, the force can be transmitted to the sliding ring through the arc-shaped column, causing the sliding ring to slide inside the pipe, thereby achieving the connection or separation of the mud inlet / outlet mechanism from the pipe.

[0024] As a further description of the above technical solution:

[0025] The sliding plate is externally slidably connected to the inside of the support frame, and the two limiting frames are respectively fixedly connected to the two distant sides of the support frame.

[0026] The above scheme allows the sliding plate to slide inside the support frame, providing guidance and support to ensure its stability during movement. The two limit frames on both sides are fixed to the outside of the two support frames to limit the sliding range of the sliding plate and prevent it from deviating or leaving the track during movement.

[0027] As a further description of the above technical solution:

[0028] The two transmission plates are slidably connected to the upper and lower ends of the pipe, respectively, and the sealing ring is slidably connected to the inside of the connecting ring.

[0029] With the above scheme, the two transmission plates slide inside the upper and lower ends of the pipe, which can effectively transmit external force and drive the quick-release mechanism to achieve quick connection or separation between the mud inlet / outlet mechanism and the pipe. The sealing ring slides inside the connecting ring, and after the connection operation is completed, it can fit tightly to form a reliable sealing structure.

[0030] This utility model has the following beneficial effects:

[0031] 1. In this utility model, by fully engaging the sliding ring inside the sliding ring, and then releasing the thrust on the reset component, the force of the spring reset is transmitted to the connecting ring through the connecting plate to slide. During the sliding process of the connecting plate, the transmission plate will also slide and abut against the arc-shaped column, so that the two arc-shaped columns are engaged inside the sliding ring, thereby quickly completing the disassembly and assembly.

[0032] 2. In this utility model, the sliding plate is pushed by the rotating plate to slide, and the inclined plate is pushed by the sliding plate to rotate, which in turn drives the sliding plate to slide down along the support frame. Subsequently, the sliding plate pushes the reinforcing plate to slide down and abut against the ground to complete the support and reinforcement, thereby improving the stability of the device operation.

Detailed Implementation

[0040] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0041] Example: Refer to Figures 1 to 3This utility model provides an embodiment of a grouting device for dam construction, including a grouting pump 1, which is a single-cylinder type. Both ends of the grouting pump 1 are fixedly connected to pipes 2. The pipe 2 at the bottom of the grouting pump 1 is used to feed concrete, and the pipe 2 at the top is used to discharge concrete. A diaphragm accumulator 3 is fixedly connected inside one of the pipes 2. When the pump discharge pressure increases, it stores energy; when the pressure decreases, it releases energy, forming a "pressure buffer zone." A quick-release mechanism 4 is slidably connected to the left end of the pipe 2. Both quick-release mechanisms 4 include connecting rings 41, which are hollow rings. The interior of the connecting ring 41 is slidably connected to the outside of the pipe 2. The pipe 2 restricts the connection, allowing the connecting ring 41 to slide stably. Two connecting plates 42 are fixedly connected to the right side of the connecting ring 41. By pushing the connecting ring 41... The slide proceeds, causing the connecting plate 42 to slide synchronously. A reset component 43 is fixedly connected to the right side of the connecting plate 42, providing a reset force to the connecting plate 42. Multiple reset components 43 each include a connecting plate 4301. The outer sides of two connecting plates 4301 are slidably connected to the inner sides of the upper and lower ends of the pipe 2. The pipe 2 restricts the connecting plate 4301, allowing it to slide stably. The left side of the connecting plate 4301 is fixedly connected to the right side of the connecting plate 42, transmitting the sliding force to the connecting plate 4301 through the connecting plate 42. A spring 4302 is fixedly connected to the right side of the connecting plate 4301. During the sliding process, the connecting plate 4301 is compressed, allowing it to release its elastic potential energy, which in turn provides a force in the opposite direction to the spring 4302 for reset.

[0042] Specifically, the grouting pump 1 delivers concrete through pipes 2 at both ends. The bottom pipe 2 is used for concrete inlet, and the top pipe 2 is used for concrete outlet. The diaphragm accumulator 3 inside the pipe 2 can store energy when the pump discharge pressure increases and release energy when the pressure decreases, forming a "pressure buffer" to stabilize the pressure. In the quick-release mechanism 4 at the left end of the pipe 2, the hollow annular connecting ring 41 is slidably connected to the outside of the pipe 2, and its sliding trajectory is restricted by the pipe 2. The connecting plate 42 on the right side of the connecting ring 41 can slide synchronously with the connecting ring 41. The reset component 43 on the right side of the connecting plate 42 provides reset force to the connecting plate 42 through the connecting plate 4301 and the spring 4302. The connecting plate 4301 is slidably connected to the inside of the upper and lower ends of the pipe 2 respectively. The left side is fixedly connected to the connecting plate 42. The spring 4302 on the right side is squeezed and stores elastic potential energy when the connecting plate 4301 slides, and then pushes the connecting plate 4301 to reset through the opposite force, realizing the convenient connection and separation function of the quick-release mechanism 4.

[0043] Reference Figures 2 to 4The right ends of two springs 4302 are fixedly connected to the inner walls of the upper and lower ends of the pipe 2. By fixing the springs 4302, the force on the springs 4302 is evenly distributed. A transmission plate 44 is fixedly connected to the left side of the connecting plate 42. The sliding force is transmitted to the transmission plate 44 through the connecting plate 42. The outer sides of the two transmission plates 44 are slidably connected to the inner walls of the upper and lower ends of the pipe 2. The pipe 2 restricts the movement of the transmission plates 44. Arc-shaped columns 45 are slidably connected to both the upper and lower ends of the pipe 2. The pipe 2 restricts the movement of the transmission plates 44. The arc-shaped column 45 can slide up and down. The far sides of the two arc-shaped columns 45 are slidably connected to the near sides of the two transmission plates 44. During the sliding process, the transmission plates 44 will abut against the two arc-shaped columns 45, so that the two arc-shaped columns 45 can slide to the near side. The outer side of the arc-shaped column 45 is slidably connected to the limit ring 46, which provides support for the arc-shaped column 45 and prevents the arc-shaped column 45 from slipping. The left side of the connecting ring 41 is fixedly connected to the sealing ring 47, and the sliding of the connecting ring 41 drives the sealing ring 47 to slide synchronously.

[0044] Specifically, the right end of spring 4302 is fixed to the upper and lower inner walls of pipe 2 to ensure uniform force distribution and provide elastic potential energy for structural reset. Connecting plate 42 transmits the sliding force to transmission plate 44. When transmission plate 44 slides stably in pipe 2, it abuts against arc-shaped column 45 to make it slide to the same side. Limiting ring 46 supports arc-shaped column 45 to prevent it from slipping and ensures transmission stability. When connecting ring 41 slides, it drives sealing ring 47 on the left to slide synchronously. When connecting the mud inlet and outlet mechanism, sealing ring 47 can achieve tight sealing to prevent mud leakage. The entire structural design ensures the reliability, sealing performance and repeatability of the quick-release connection of the grouting device.

[0045] Reference Figure 1 and Figure 5 The quick-release mechanism 4 has an internal sliding connection to a mud inlet / outlet mechanism 5, which includes a sliding ring 51. The sliding ring 51 is a hollow ring, and the two arc-shaped columns 45 are slidably connected at their respective ends to the upper and lower ends of the sliding ring 51. After the arc-shaped columns 45 slide into the interior of the sliding ring 51, they engage with the sliding ring 51. The outer side of the sliding ring 51 is slidably connected to the interior of the pipe 2. The pipe 2 restricts the sliding ring 51 so that it can slide stably. The left end of the sliding ring 51 is fixedly connected to a connecting ring 52, which is fixed by welding to provide support for the sliding ring 51. The outer side of the sealing ring 47 is slidably connected to the interior of the connecting ring 52. The sealing ring 47 slides into the interior of the connecting ring 52 to engage and seal, thereby improving the sealing effect. The left end of the connecting ring 52 is fixedly connected to a pipe body 53. The upper end of the pipe body 53 is used to extract concrete, and the lower end of the pipe body 53 is used to suck in concrete.

[0046] Specifically, the arc-shaped column 45 inside the quick-release mechanism 4 slides into the upper and lower ends of the sliding ring 51 in the mud inlet / outlet mechanism 5, firmly connecting the sliding ring 51 with the quick-release mechanism 4. At the same time, the sliding ring 51 slides stably in the pipe 2, ensuring connection stability. The connecting ring 52, which is welded and fixed to the left end of the sliding ring 51, provides support for it. The sealing ring 47 slides into the inside of the connecting ring 52 to form a sealing structure, effectively preventing mud leakage. The pipe body 53 at the left end of the connecting ring 52 is used to extract concrete at the upper end and to suck in concrete at the lower end. The quick disassembly and assembly of the quick-release mechanism 4 and the mud inlet / outlet mechanism 5 facilitates equipment connection and maintenance.

[0047] Two support frames 6 are fixedly connected to the bottom side of the grouting pump 1, providing support for the grouting pump 1. Support plates 7 are fixedly connected inside the two support frames 6, connecting the two support frames 6 into one unit. A reinforcing mechanism 8 is fixedly connected to the top side of the support plate 7. The reinforcing mechanism 8 includes a cylinder 81, which provides a driving source. The bottom side of the cylinder 81 is fixedly connected to the top side of the support plate 7. By fixing the cylinder 81, the cylinder 81 can operate stably. An opening plate 82 is fixedly connected to the driving end of the cylinder 81. By starting the cylinder 81, the opening plate 82 is driven to slide. Rotating plates 83 are rotatably connected to both the front and rear ends of the opening plate 82. By sliding the opening plate 82, the two rotating plates 83 are pushed to rotate. A sliding plate 84 is rotatably connected to the far end of the two rotating plates 83. The rotating plate 83 transmits the rotational force to the sliding plate 84, enabling the rotating plate 83 to slide stably.

[0048] Specifically, the reinforcement mechanism 8 on the top side of the support plate 7 is driven by a cylinder 81. The cylinder 81 is fixed to the top side of the support plate 7 to ensure stable operation. When the cylinder 81 is started, the open plate 82 connected to the drive end begins to slide. The rotating plates 83 at the front and rear ends of the open plate 82 rotate accordingly and transmit the rotational force to the sliding plate 84, causing the sliding plate 84 to slide stably. This achieves the function of the reinforcement mechanism 8 in stabilizing and adjusting the grouting device, ensuring that the grouting pump 1 remains stable during the grouting process of the dam construction.

[0049] The sliding plate 84 is externally slidably connected to the inside of the support frame 6. The support frame 6 restricts the sliding plate 84, allowing it to slide stably. An inclined plate 85 is rotatably connected inside the sliding plate 84. The sliding plate 84 drives the inclined plate 85 to rotate. Two sliding plates 86 are rotatably connected to the outside of the inclined plate 85. The inclined plate 85 transmits the rotational force to the sliding plates 86, causing them to slide. Limiting frames 87 are externally slidably connected to the two sliding plates 86. The limiting frames 87 guide the sliding plates 86. The adjacent sides of the two limiting frames 87 are fixedly connected to the distant sides of the two support frames 6 by welding, thus providing support for the limiting frames 87. A reinforcing plate 88 is fixedly connected to the bottom side of the two sliding plates 86. The sliding plate 86 pushes the reinforcing plate 88 downward to slide against the ground for reinforcement.

[0050] Specifically, the sliding plate 84 slides stably under the constraint of the support frame 6. The inclined plate 85, which is rotatably connected inside, rotates under the drive of the sliding plate 84 and transmits the rotational force to the sliding plate 86. The sliding plate 86 slides under the guidance of the limiting frame 87, which is fixed to the support frame 6 by welding to ensure the accuracy of the sliding plate 86's movement trajectory. Finally, the sliding plate 86 pushes the bottom reinforcing plate 88 to slide downward, so that it touches the ground, effectively enhancing the stability of the grouting device during construction.

[0051] Working principle: During installation, by holding the connecting ring 52, the sliding ring 51 is engaged inside the pipe 2, while the connecting ring 41 is pushed to the right, which in turn drives the connecting plate 4301 to slide. At this time, the connecting plate 4301 will compress the spring 4302, causing the transmission plate 44 to slide. The transmission plate 44 is no longer pressing against the arc-shaped column 45, and then the sliding ring 51 is fully engaged inside the sliding ring 51. Then, the pushing force on the reset assembly 43 is released, and the reset force of the spring 4302 is transmitted to the connecting ring 41 through the connecting plate 4301. During the sliding process of the connecting plate 4301, the transmission plate 44 will also slide and abut against the arc-shaped column 45, so that the two arc-shaped columns 45 are engaged inside the sliding ring 51, thereby quickly completing the disassembly and assembly. At the same time, the connecting ring 41 will drive the sealing ring 47 to engage inside the connecting ring 52 for sealing. Then, the connecting ring 52 at the bottom end is placed in the concrete. The concrete is extracted by starting the grouting pump 1 and output to the required position through the pipe 53 at the top. At the same time, the pipe 2 at the top will automatically adjust the pressure inside the pipe 2 through the diaphragm accumulator 3.

[0052] Simultaneously, cylinder 81 is activated, driving the open plate 82 to slide, which in turn drives the rotating plate 83 to rotate. The rotating plate 83 pushes the sliding plate 84 to slide, and the sliding plate 84 pushes the inclined plate 85 to rotate, which in turn drives the sliding plate 86 to slide down along the support frame 6. Subsequently, the sliding plate 86 pushes the reinforcing plate 88 to slide downward and touch the ground to complete the support and reinforcement.

[0053] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
