Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering construction technology, and in particular to a novel compaction device and its usage method for earth-rock cofferdam construction. Background Technology

[0002] During the construction of water conservancy projects, a surface layer needs to be made on the stable ground surface of the cofferdam. However, many earth and rock cofferdams are very uneven after construction. Therefore, it is necessary to use a compaction device to compact the ground to enhance the stability and bearing capacity of the cofferdam.

[0003] A search revealed, for example, Chinese Patent No. CN221372132U, which discloses a foundation leveling device for building engineering. The device includes a frame, with pulleys installed at the bottom and a hydraulic rod fixedly installed at the top. A pressure plate is fixedly connected to the output end of the hydraulic rod. A first bracket is installed at the bottom of the frame, located on one side of the pressure plate. A second bracket is slidably connected inside the first bracket. A mounting frame is fixedly connected to the bottom of the second bracket, and a pressure roller is rotatably connected inside the mounting frame. A support frame is installed at the bottom of the frame, between the pulleys and the pressure plate, and a crushing roller is rotatably connected inside the support frame. This device, through the combination of the pressure plate and the crushing roller, crushes hard blocks before compaction, resulting in good compaction of the ground after crushing.

[0004] However, the above-mentioned device has the following problems when in use:

[0005] 1. The output power of the crushing roller is the same for hard blocks of different sizes. When dealing with larger hard blocks, the crushing effect may be incomplete, and excessive torque may cause motor overload; when dealing with smaller hard blocks, the power is too high, resulting in waste of resources.

[0006] 2. The crushing height of the crushing mechanism in the above application cannot be adjusted, making it unable to adapt to construction environments of different heights; and the rollers cannot be fixed during operation, causing them to roll and affecting the compaction effect. Summary of the Invention

[0007] To overcome the above deficiencies, this invention provides a novel compaction device and method for constructing earth-rock cofferdams. It has the function of real-time monitoring of the size of the hard blocks and adjusting the motor speed according to the size of the hard blocks. The crushing depth can also be adjusted, which enhances the applicability of the crushing device and achieves better crushing effect.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a novel compaction device for earth-rock cofferdam construction, comprising an installation frame and a control module, wherein a compaction mechanism and a crushing mechanism are provided on the lower side of the inner bottom wall of the installation frame, and a support mechanism is provided at the bottom of the installation frame;

A threaded sleeve is threadedly connected to the outer surface of the threaded rod. A movable plate is fixedly installed at the bottom of the threaded sleeve. Telescopic rods are fixedly installed between the top two ends of the movable plate and the inner bottom wall of the mounting frame. A support frame is fixedly installed at the bottom of the movable plate. A crushing motor is fixedly installed on the front side wall of the support frame. A crushing roller is fixedly installed at the output shaft of the crushing motor.

[0010] The control module includes a controller, an ultrasonic ranging sensor, and a microwave sensor. The controller is fixedly installed on the top of the mounting bracket, and the ultrasonic ranging sensor and the microwave sensor are both fixedly installed on the bottom of the movable plate.

[0011] Preferably, the compaction mechanism includes a fixed box fixedly installed on the inner bottom wall of the mounting frame. A compaction motor is installed inside the fixed box. A turntable is fixedly installed at the output shaft of the compaction motor. Fixed rods are fixedly installed between the left and right ends of the inner top wall and inner bottom wall of the fixed box. Sliding sleeves are slidably installed on the outer surfaces of the two fixed rods. A crossbar is fixedly installed on the opposite side of the two sliding sleeves. A movable frame is fixedly installed between the two crossbars. A guide rod is fixedly installed at the bottom of the movable frame. A compaction block is fixedly installed at the bottom of the guide rod. Crushing teeth are evenly distributed at the bottom of the compaction block.

[0012] Preferably, the support mechanism includes receiving cavities formed on the left and right inner walls of the mounting frame. An electric push rod is fixedly installed on the inner top wall of each of the two receiving cavities. A sliding plate is fixedly installed on the bottom of each of the two electric push rods. A connecting rod is rotatably installed on the front and rear sides of each of the two sliding plates. A support block is rotatably installed between one end of each pair of connecting rods. One side of each of the two support blocks is rotatably connected to the lower end of the side wall of the mounting frame.

[0013] Preferably, a protruding rod located inside the movable frame is fixedly installed on the front side wall of the turntable, and the movable frame is movably installed on the outer surface of the protruding rod.

[0014] Preferably, the bottom center of the fixed box has an opening that matches the guide rod, and one end of the guide rod passes through the opening and extends to the top of the compacted block.

[0015] Preferably, guide grooves are provided on the side walls of both receiving cavities, and guide blocks are fixedly installed on one side of both sliding plates, and both guide blocks are slidably connected to the guide grooves.

[0016] Preferably, the mounting bracket is provided with casters at both ends of its bottom, a handle is fixedly installed on the front side wall of the mounting bracket, and a power supply is provided inside the mounting bracket.

[0017] Preferably, the ultrasonic ranging sensor and the microwave sensor are connected to the controller via wireless communication technology, the crushing motor is an adjustable speed motor and is connected to the controller via wires, and the lifting motor is connected to the controller via wires.

[0018] A method for using a novel compaction device for earth-rock cofferdam construction includes the following steps:

[0019] Step S1: First, move the device to the location that needs to be compacted using the moving wheels. After reaching the destination, start the electric push rod to drive the slide plate to slide down in the guide groove through the guide block. The slide plate drives the connecting rod to rotate, thereby causing the support block to flip down and make the two support blocks contact the ground for stable support.

[0020] Step S2: When the compacted area needs to be crushed, the ultrasonic ranging sensor and microwave sensor analyze the distance to the hard block and the size of the hard block in real time and feed it back to the controller. The controller sends corresponding instructions to the lifting motor and the crushing motor according to the processing results. The lifting motor drives the threaded rod to rotate, the threaded rod drives the threaded sleeve to move downward, the threaded sleeve drives the moving plate to move downward so that the two telescopic rods extend. The moving plate drives the support frame and the crushing roller to descend. After the crushing roller is adjusted to a suitable crushing height, the crushing motor rotates at the corresponding speed according to the instructions, driving the crushing roller to rotate and crush the hard block.

[0021] Step S3: After crushing is completed, start the tamping motor. The tamping motor drives the turntable to rotate, the turntable drives the cam to rotate, and the cam drives the movable frame to slide up and down on the outer surface of the fixed rod through the sliding sleeve. The movable frame drives the guide rod to move up and down, and the guide rod drives the tamping block to move up and down. With the tamping block moving up and down back and forth, the tamping work is carried out. During the tamping process, the crushing teeth further crush the hard blocks that are not completely crushed.

[0022] The present invention has the following beneficial effects:

[0023] 1. In this invention, the distance to the hard block and the size of the hard block are analyzed in real time by ultrasonic ranging sensors and microwave sensors and fed back to the controller. The controller sends corresponding instructions to adjust the depth of the crushing roller and the speed of the crushing motor. The combination of the two makes it easier to process hard blocks of different sizes. The addition of crushing teeth at the bottom of the compaction block further enhances the crushing effect during the compaction process. The ground after crushing is easier to achieve uniform compaction, which improves the compaction effect and the quality of the project.

[0024] 2. In this invention, by setting up a support mechanism, the stability of the device is ensured during crushing and compaction, preventing rolling and thus improving the compaction effect and operational safety. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1: Refer to Figure 1-3A novel compaction device for earth-rock cofferdam construction includes an installation frame 1 and a control module. The lower side of the inner bottom wall of the installation frame 1 is provided with a compaction mechanism 2 and a crushing mechanism 3. The bottom of the installation frame 1 is provided with a support mechanism 4. The crushing mechanism 3 includes a lifting motor 301 fixedly installed on the inner bottom wall of the installation frame 1. A threaded rod 302 is fixedly installed at the output shaft of the lifting motor 301. A threaded sleeve 303 is threadedly connected to the outer surface of the threaded rod 302. A movable plate 304 is fixedly installed at the bottom of the threaded sleeve 303. Telescopic rods 305 are fixedly installed between the top two ends of the movable plate 304 and the inner bottom wall of the installation frame 1. A support frame 306 is fixedly installed at the bottom of the movable plate 304. A crushing motor 307 is fixedly installed on the front side wall of the support frame 306. A crushing roller 308 is fixedly installed at the output shaft of the crushing motor 307.

[0035] Through the cooperation of threaded rod 302, threaded sleeve 303 and telescopic rod 305, when the lifting motor 301 is running, it drives the threaded rod 302 to rotate, and at the same time drives the moving plate 304 to rise and fall, thereby adjusting the height of the crushing roller 308. The crushing roller 308 is adjusted to a suitable position to crush the hard block according to the required crushing height and the hardness of the block, thus solving the problem that the working height of the crushing mechanism cannot be adjusted.

[0036] The control module includes a controller 8, an ultrasonic ranging sensor 309, and a microwave sensor 310. The controller 8 is fixedly installed on the top of the mounting bracket 1. The ultrasonic ranging sensor 309 and the microwave sensor 310 are both fixedly installed on the bottom of the moving plate 304. The ultrasonic ranging sensor 309 and the microwave sensor 310 are connected to the controller 8 through wireless communication technology. The crushing motor 307 is an adjustable speed motor and is connected to the controller 8 through a wire. The lifting motor 301 is connected to the controller 8 through a wire.

[0037] The ultrasonic ranging sensor 309 emits ultrasonic pulses, receives the echoes reflected from the ground, calculates the distance to the ground using the time difference, and feeds this data back to the controller 8. The controller 8 sends instructions to the lifting motor 301 based on the data. The lifting motor 301 then lowers the crushing roller 308 to the construction height to prevent the crushing roller 308 from lowering too much, which would cause excessive torque and motor overload in the crushing motor 307; or to prevent the crushing motor from idling due to insufficient descent. The microwave sensor 310 emits millimeter-wave electromagnetic waves and analyzes the size and state of the stone particles by combining the Doppler effect or changes in reflection intensity. This data is fed back to the controller 8, which sends instructions to the crushing motor 307 based on the data. The crushing motor 307 adjusts its speed according to the instructions to correspond to different sizes of hard blocks.

[0038] Example 2: Refer to Figure 4-5The compaction mechanism 2 includes a fixed box 201 fixedly installed on the inner bottom wall of the mounting frame 1. A compaction motor 202 is installed inside the fixed box 201. A turntable 203 is fixedly installed at the output shaft of the compaction motor 202. Fixed rods 204 are fixedly installed between the left and right ends of the inner top wall and inner bottom wall of the fixed box 201. Sliding sleeves 205 are slidably installed on the outer surface of the two fixed rods 204. A crossbar 206 is fixedly installed on the opposite side of the two sliding sleeves 205. A movable frame 207 is fixedly installed between the two crossbars 206. A guide rod 208 is fixedly installed at the bottom of the movable frame 207. A compaction block 209 is fixedly installed at the bottom of the guide rod 208. Crushing teeth 210 are evenly distributed at the bottom of the compaction block 209.

[0039] To improve the stability of the tamping motor 202, a support platform is fixedly installed on the inner bottom wall of the fixed box 201. The tamping motor 202 is fixedly installed on the support platform. A through-hole adapted to the guide rod 208 is opened in the middle of the bottom of the fixed box 201. By setting the through-hole, space is provided for the guide rod 208 to move up and down, thereby facilitating the up and down movement of the tamping block 209. During the tamping process, the crushing teeth 210 further crush the hard blocks on the ground, enhancing the tamping effect.

[0040] A protruding rod is fixedly installed on the front side wall of the turntable 203, inside the movable frame 207. The movable frame 207 is movably installed on the outer surface of the protruding rod. Through the cooperation of the protruding rod, the crossbar 206, the sliding sleeve 205 and the fixed rod 204, when the compaction motor 202 is operating, the rotation of the turntable 203 can drive the movable frame 207 to move up and down reciprocally, thereby driving the compaction block 209 to move up and down reciprocally for hammering. The rotational kinetic energy is effectively converted into linear kinetic energy, realizing rapid compaction and hammering, thereby improving compaction efficiency and work effect. This structural design enables the device to compact the ground quickly and effectively in engineering.

[0041] Example 3, referring to Figure 6 The support mechanism 4 includes receiving cavities 401 opened on the left and right inner walls of the mounting frame 1. Electric push rods 402 are fixedly installed on the inner top walls of the two receiving cavities 401. Slide plates 403 are fixedly installed on the bottom of the two electric push rods 402. Connecting rods 404 are rotatably installed on the front and rear sides of the two slide plates 403. A support block 405 is rotatably installed between one end of each pair of connecting rods 404. One side of each support block 405 is rotatably connected to the lower end of the side wall of the mounting frame 1.

[0042] Guide grooves 406 are provided on the side walls of both receiving cavities 401, and guide blocks 407 are fixedly installed on one side of both sliding plates 403. The sliding cooperation of the guide grooves 406 and guide blocks 407 improves the stability of the sliding plates 403 when moving up and down. When the sliding plates 403 move upward, the rotation of the connecting rod 404 can drive the support block 405 to flip upward and move using the moving wheels 5. After the device is moved to the destination, the downward movement of the sliding plates 403 can cause the support block 405 to flip downward and become parallel to the ground, using the support block 405 for support. During the construction process, the entire device will be stable on the ground and will not roll, improving the compaction effect and operational safety. A handle 6 is fixedly installed on the front side wall of the mounting frame 1, and a power supply 7 is installed inside the mounting frame 1. With the help of the handle 6 and the moving wheels 5, the position of the device can be moved easily and conveniently. The power supply 7 is the power source of the device.

[0043] Working principle: First, the device is moved to the location requiring compaction using the moving wheels 5. Upon arrival, the electric push rod 402 is activated, causing the sliding plate 403 to slide downwards through the guide block 407 within the guide groove 406. The sliding plate 403 drives the connecting rod 404 to rotate, thereby causing the support block 405 to flip downwards, allowing the two support blocks 405 to contact the ground for stable support. Then, when the compacted area needs to be broken up, the ultrasonic ranging sensor 309 and the microwave sensor 310 analyze the distance to the hardened block and the size of the hardened block in real time and feed back to the controller 8. The controller 8 sends corresponding instructions to the lifting motor 301 and the crushing motor 307 according to the processing results. The lifting motor 301 drives the threaded rod 302 to rotate, the threaded rod 302 drives the threaded sleeve 303 to move downward, the threaded sleeve 303 drives the moving plate 304 to move downward, so that the two telescopic rods 305 are extended. The moving plate 304 drives the support frame 306 and the crushing roller 308 to descend. After the crushing roller 308 is adjusted to a suitable crushing height, the crushing motor 307 rotates at the corresponding speed according to the instructions, driving the crushing roller 308 to rotate and crush the hard block.

[0044] After crushing is completed, the compaction motor 202 is started. The compaction motor 202 drives the turntable 203 to rotate, the turntable 203 drives the convex rod to rotate, and the convex rod drives the movable frame 207 to slide up and down on the outer surface of the fixed rod 204 through the sliding sleeve 205. The movable frame 207 drives the guide rod 208 to move up and down, and the guide rod 208 drives the compaction block 209 to move up and down. Under the reciprocating up and down movement of the compaction block 209, the compaction work is carried out. During the compaction process, the crushing teeth 210 further crush the hard blocks that are not completely crushed.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
