Description

Technical Field

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

[0002] In the construction of water conservancy projects, the construction of grouting holes is a crucial step. However, existing reaming devices present numerous problems when reaming holes require enlargement. Some devices have simple structures, making them unsuitable for reaming operations under varying geological conditions, resulting in low reaming efficiency. Other devices exhibit poor stability during reaming, prone to swaying, which compromises the accuracy of the reaming and affects the quality of subsequent grouting work. Furthermore, most devices lack real-time monitoring capabilities for reaming parameters, hindering timely adjustments and further reducing construction efficiency and quality. Therefore, there is an urgent need to design a new type of grouting hole reaming device for water conservancy construction to address these issues.

[0003] Regarding the above-mentioned and existing related technologies, the inventor believes that the following defects often exist: if the driven frame is stuck, the hole enlargement operation will stop, causing the mud in the hole to stand still for a long time, resulting in sedimentation or deterioration. The drive motor will overheat and wear due to overload operation. Long-term overload will cause the seals to age and leak, increasing maintenance costs. Replacing parts requires production stoppage for maintenance, which prolongs the downtime. Therefore, in order to address the above problems, a hole enlargement device for grouting holes in water conservancy construction is proposed. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of the existing technology, such as if the driven frame gets stuck, the hole enlargement operation will stop, causing the mud in the hole to stand still for a long time, resulting in sedimentation or deterioration. The drive motor will overheat and wear due to overload operation. Long-term overload will cause the seals to age and leak, increasing maintenance costs. Replacing parts requires production stoppage for maintenance, which prolongs the downtime. Therefore, a hole enlargement device for grouting holes in water conservancy construction is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a hole expansion device for grouting in hydraulic construction, comprising a bottom pipe, a sliding rod slidably connected to the inner surface of the bottom pipe, an expansion device provided on the surface of the sliding rod, the expansion device comprising a fixing plate, the fixing plate being fixedly connected to the surface of the sliding rod, a round rod being fixedly connected to the inner surface of the fixing plate, a rotating frame being rotatably connected to the arc surface of the round rod, a setting rod being fixedly connected to the inner surface of the rotating frame, a driven frame being rotatably connected to the arc surface of the setting rod, a setting plate being fixedly connected to the arc surface of the bottom pipe, a driving rod being fixedly connected to the inner surface of the setting plate, and the arc surface of the driving rod being rotatably connected to the driven frame.

[0006] The effect achieved by the above-mentioned components is as follows: by setting up the expansion device, the driven frame of the grouting hole expansion device in water conservancy construction is expanded or retracted. If the driven frame is stuck, the hole expansion operation will stop, causing the mud in the hole to stand still for a long time, resulting in sedimentation or deterioration. The drive motor will overheat and wear due to overload operation. Long-term overload will cause the seals to age and leak, increasing maintenance costs. Replacing the parts requires production stoppage for inspection and maintenance, extending the downtime.

[0007] Preferably, the arc surface of the sliding rod is fixedly connected to two side plates, and a fixed rod is fixedly connected to the side of the two side plates that are close to each other. The arc surface of the fixed rod is rotatably connected to a setting tube, and the arc surface of the setting tube is fixedly connected to a hollow tube. The inner surface of the hollow tube is slidably connected to a telescopic rod, and one end of the telescopic rod is fixedly connected to a rotating tube. The surface of the rotating frame is fixedly connected to two clamping plates, and a connecting rod is fixedly connected to the side of the two clamping plates that are close to each other. One end of the telescopic rod is fixedly connected to the rotating tube.

[0008] The effect achieved by the above components is to limit the position of the rotating frame and prevent the rotating frame and rotating mechanism from rotating during operation.

[0009] Preferably, the hollow tube has a rod slidably inserted into its arc surface, and the telescopic rod has several circular holes on its arc surface.

[0010] The aforementioned components achieve the following effect: limiting the position of the hollow tube and telescopic rod, further ensuring the stability of the device during operation.

[0011] Preferably, a spring is fitted onto the arc surface of the insertion rod, and the two ends of the spring are fixedly connected to one end of the insertion rod and the arc surface of the hollow tube, respectively.

[0012] The effect achieved by the above components is that the spring force automatically pushes the insertion rod into the round hole of the telescopic rod.

[0013] Preferably, the surface of the bottom tube is provided with an auxiliary device, the auxiliary device including an upper ring, the upper ring being fixedly connected to the surface of the bottom tube, the surface of the upper ring being provided with a positioning hole, the arc surface of the bottom tube being rotatably connected to a circular shaft, the arc surface of the circular shaft being fixedly connected to three mounting rods, and the end of the mounting rod away from the circular shaft being fixedly connected to an arc rod.

[0014] The effect achieved by the above-mentioned components is that by setting up auxiliary devices, it is possible for workers to easily fold up and transport the driven frame, avoiding the cumbersome operation when workers fold up the driven frame. Usually, the driven frame of the traditional construction grouting hole expansion device needs to be wrapped with special bandages before it can be transported, and workers need to spend a lot of time folding it up, which reduces work efficiency.

[0015] Preferably, a torsion spring is fitted onto the arc surface of the bottom tube, and the two ends of the torsion spring are fixedly connected to one side of the upper ring and one end of the circular shaft, respectively.

[0016] The effect achieved by the above components is that the torsion of the torsion spring causes the arc rod to automatically return to its original position, preventing the driven frame from moving.

[0017] Preferably, a limiting rod is slidably inserted into the inner surface of the positioning hole, and the size of the round shaft is adapted to the size of the bottom tube.

[0018] The effect achieved by the above components is that when the worker retracts the driven frame to the inside of the arc rod, the limiting rod blocks the mounting rod, preventing the driven frame from detaching from the arc rod due to the shaking of the round shaft during transportation.

[0019] In summary, the beneficial effects of this utility model are as follows:

[0020] 1. In this utility model, by setting an expansion device, the driven frame of the grouting hole expansion device in water conservancy construction is expanded or retracted. If the driven frame is stuck, the hole expansion operation will stop, causing the mud in the hole to stand still for a long time, resulting in sedimentation or deterioration. The drive motor will overheat and wear due to overload operation. Long-term overload will cause the seals to age and leak, increasing maintenance costs. Replacing parts requires production stoppage for maintenance, extending the downtime.

[0021] 2. In this utility model, by setting an auxiliary device, the effect of making it easier for workers to fold up and transport the driven frame is achieved, avoiding the cumbersome operation of workers when folding up the driven frame. Usually, the driven frame of the traditional construction grouting hole expansion device needs to be wrapped with special bandages before it can be transported, and workers need to spend a lot of time folding it up, which reduces work efficiency.

[0029] Reference Figure 1 As shown, this utility model provides a technical solution: a hole-expanding device for hydraulic construction grouting holes, including a bottom pipe 1. A sliding rod 2 is slidably connected to the inner surface of the bottom pipe 1, and an expansion device 3 is provided on the surface of the sliding rod 2. By setting the expansion device 3, the driven frame 305 of the hole-expanding device for hydraulic construction grouting holes can be expanded or retracted. If the driven frame 305 is stuck, the hole-expanding operation will stop, causing the mud in the hole to stand still for a long time, resulting in sedimentation or deterioration. The drive motor will overheat and wear due to overload operation. Long-term overload will cause the seals to age and leak, increasing maintenance costs. Replacing parts requires production stoppage for maintenance, extending downtime. The surface of the bottom pipe 1 is provided with an auxiliary device 4. By setting the auxiliary device 4, the driven frame 305 can be easily retracted and transported by the workers, avoiding the cumbersome operation when retracting the driven frame 305. Usually, the driven frame 305 of the traditional hole-expanding device for hydraulic construction grouting holes needs to be wrapped with special bandages before transportation, which requires workers to spend a lot of time retracting it, reducing work efficiency.

[0030] The specific configuration and function of its expansion device 3 and auxiliary device 4 will be explained below.

[0031] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5As shown in this embodiment: the expansion device 3 includes a fixed plate 301, which is fixedly connected to the surface of the sliding rod 2. A round rod 302 is fixedly connected to the inner surface of the fixed plate 301. A rotating frame 303 is rotatably connected to the arc surface of the round rod 302. A setting rod 304 is fixedly connected to the inner surface of the rotating frame 303. A driven frame 305 is rotatably connected to the arc surface of the setting rod 304. A setting plate 307 is fixedly connected to the arc surface of the bottom tube 1. A driving rod 306 is fixedly connected to the inner surface of the setting plate 307. The arc surface of the driving rod 306 is rotatably connected to the driven frame 305. Two side plates 308 are fixedly connected to the arc surface of the sliding rod 2. A fixing rod 309 is fixedly connected to the side of the two side plates 308 that are close to each other. A setting tube 310 is rotatably connected to the arc surface of the fixing rod 309. A hollow tube 311 is fixedly connected to the arc surface of the setting tube 310. A telescopic rod 312 is slidably connected to the inner surface of the hollow tube 311. A rotating tube 315 is fixedly connected to one end of the telescopic rod 312. Two clamping plates 313 are fixedly connected to the surface of the rotating frame 303. A connecting rod 314 is fixedly connected to the side of the two clamping plates 313 that are close to each other. One end of the telescopic rod 312 is fixedly connected to the rotating tube 315. The position of the rotating frame 303 is limited to prevent the rotating frame 303 from rotating during operation. An insert rod 316 is slidably inserted into the arc surface of the hollow tube 311, and several circular holes are opened on the arc surface of the telescopic rod 312. The positions of the hollow tube 311 and the telescopic rod 312 are limited to further ensure the stability of the device during operation. A spring 317 is fitted onto the arc surface of the insertion rod 316, with both ends of the spring 317 fixedly connected to one end of the insertion rod 316 and the arc surface of the hollow tube 311, respectively. The elastic force of the spring 317 automatically propels the insertion rod 316 into the circular hole of the telescopic rod 312.

[0032] Reference Figure 6 As shown, specifically, the auxiliary device 4 includes an upper ring 41, which is fixedly connected to the surface of the bottom tube 1. A positioning hole 42 is provided on the surface of the upper ring 41. A circular shaft 43 is rotatably connected to the arc surface of the bottom tube 1. Three mounting rods 44 are fixedly connected to the arc surface of the circular shaft 43. An arc rod 45 is fixedly connected to the end of each mounting rod 44 away from the circular shaft 43. A torsion spring 46 is fitted onto the arc surface of the bottom tube 1. Both ends of the torsion spring 46 are fixedly connected to one side of the upper ring 41 and one end of the circular shaft 43, respectively. The torsion of the torsion spring 46 causes the arc rod 45 to automatically return to its original position, preventing the driven frame 305 from moving. A limiting rod 47 is slidably inserted into the inner surface of the positioning hole 42. The size of the circular shaft 43 is adapted to the size of the bottom tube 1. When the worker retracts the driven frame 305 to the inside of the arc rod 45, the limiting rod 47 blocks the mounting rod 44 to prevent the driven frame 305 from detaching from the arc rod 45 during transportation due to the shaking of the shaft 43.

[0033] Working principle: When the operator needs to adjust the expansion degree of the driven frame 305 using the expansion device 3, the insertion rod 316 is first slid on the inner surface of the hollow tube 311. When the insertion rod 316 disengages from the round hole on the surface of the telescopic rod 312, the spring 317 is stretched, and then the sliding rod 2 is pulled to slide on the inner surface of the bottom tube 1, thereby causing the fixed plate 301 to slide downward. Due to the connection of the round rod 302, the rotating frame 303 rotates on the arc surface of the round rod 302, driving the setting rod 304 to move, thereby causing the driven frame 305 to rotate on the arc surface of the setting rod 304. Since the setting plate 307 is fixedly connected to the bottom tube 1, the driven frame 305 is driven by the driving rod 306. The arc surface rotates, causing the driven frame 305 to expand. The setting tube 310 on the surface of the fixing rod 309 between the side plates 308 of the arc surface of the sliding rod 2 begins to rotate on the arc surface of the fixing rod 309, driving the hollow tube 311 to rotate. The rotating tube 315 on the surface of the connecting rod 314 between the clamping plates 313 on one side of the rotating frame 303 begins to rotate on the arc surface of the connecting rod 314, driving the telescopic rod 312 to rotate. When the driven frame 305 expands to a suitable extent, the insertion rod 316 is released, the spring 317 rebounds, and slides on the inner surface of the hollow tube 311. When the insertion rod 316 enters the round hole on the surface of the telescopic rod 312, the expansion of the driven frame 305 is completed.

[0034] When the staff needs to use the auxiliary device 4 to retract the driven frame 305, first rotate the circular shaft 43 so that the circular shaft 43 rotates on the arc surface of the bottom tube 1 and drives the mounting rod 44 and the arc rod 45 to rotate. When it rotates to a certain extent, the sliding limit rod 47 slides on the inner surface of the positioning hole 42 on the surface of the upper ring 41, so that the limit rod 47 blocks the rotation of the mounting rod 44. The torsion spring 46 is compressed. When the driven frame 305 is retracted to one side of the arc rod 45, the sliding limit rod 47 slides on the inner surface of the positioning hole 42 on the surface of the upper ring 41 until the limit rod 47 disengages from the inner surface of the positioning hole 42. Under the torque of the torsion spring 46, the arc rod 45 blocks the driven frame 305. Then the sliding limit rod 47 slides on the inner surface of the positioning hole 42 on the surface of the upper ring 41 to prevent the driven frame 305 from disengaging from the arc rod 45.

[0035] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
