Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 As shown, a grouting device for filling karst caves under municipal roads includes a grouting machine body 1. The grouting machine body 1 is provided with a lifting structure 2. The lifting structure 2 includes a first hydraulic rod 201 installed on the grouting machine body 1. A lifting plate 202 is fixedly connected to the telescopic end of the first hydraulic rod 201. An installation box 203 is fixedly connected to the lifting plate 202. An adjusting rod 204 is rotatably connected to the installation box 203. Two clamping rods 205 are installed on the adjusting rod 204. One clamping rod 205 is slidably connected to the adjusting rod 204, and the other clamping rod 205 is fixedly connected to the adjusting rod 204. A guide plate 207 is fixedly connected to one of the clamping rods 205. A second hydraulic rod 208 is installed on the adjusting rod 204. The guide plate 207 is fixedly connected to the telescopic end of the second hydraulic rod 208.

[0023] As a technical optimization of this utility model, a rubber pad 206 is fixedly connected to the clamping rod 205, a guide rod 213 is fixedly connected to the lifting plate 202, the guide rod 213 is slidably connected to the grouting machine body 1, a guide rail 209 is fixedly connected to the grouting machine body 1, a counterweight 210 is slidably connected to the guide rail 209, a lead screw 211 is threadedly connected to the counterweight 210, a rotating rod 212 is fixedly connected to the lead screw 211, the lead screw 211 abuts against the guide rail 209, and the adjusting rod 204 is adjusted by the adjusting structure 3. The adjusting structure 3 includes an adjusting shaft 301 fixedly connected to the adjusting rod 204, and the adjusting shaft 301 is rotatably connected to the mounting box 203. A worm gear 302 is fixedly connected to the adjusting shaft 301. A worm 303 is rotatably connected to the mounting box 203. The worm gear 302 meshes with the worm 303. A first motor 304 is mounted on the mounting box 203. The worm 303 is fixedly connected to the output shaft of the first motor 304. When the grouting machine body 1 injects mortar into the karst cave under the road, the mortar enters the sealed chamber from the hopper. Under the push of the screw, the mortar moves forward continuously in the sealed chamber, continuously squeezing and pushing the mortar out. As the screw rotates, the mortar is pushed along the spiral channel. During the process, the volume of the chamber gradually decreases, and the mortar is squeezed and pressurized. Finally, it is injected into the karst cave under the road through the conveying pipeline under high pressure to fill the karst cave space and enhance the stability of the road foundation. When it is necessary to inject mortar into the grouting machine body... When adding slurry to the hopper on part 1, the bucket containing the slurry is placed between the two clamping rods 205. Then, the second hydraulic rod 208 is activated. When the telescopic end of the second hydraulic rod 208 retracts, it drives the guide plate 207 to slide. As the guide plate 207 slides, it drives the clamping rod 205 to slide, so that the clamping rod 205, together with another fixedly connected clamping rod 205, clamps and fixes the bucket. The rubber pad 206 on the clamping rod 205 increases the friction, making the clamping effect better. After clamping is completed, the first hydraulic rod 201 is activated. When the telescopic end of the first hydraulic rod 201 extends, it drives the lifting plate 202 to move upward. When the lifting plate 202 moves upward, it drives the guide rod 213 to slide and connect with the grouting machine body 1. The setting of the guide rod 213 allows the lifting plate 202 to slide. The lifting plate 202 drives the mounting box 203 upward, which in turn drives the bucket upward via the adjusting rod 204. When the adjusting rod 204 reaches a certain height, the first motor 304 is activated. The output shaft of the first motor 304 rotates, driving the worm gear 303 to rotate. The worm gear 303 then drives the worm wheel 302, which in turn drives the adjusting shaft 301. The adjusting shaft 301 then drives the adjusting rod 204, causing the bucket to rotate continuously. This achieves automatic pouring of slurry into the hopper of the grouting machine body 1. By adjusting the height of the bucket with the lifting plate 202, the bucket rotates, automatically pouring the slurry into the hopper. This reduces the difficulty of adding slurry to the hopper of the grouting machine body 1. Furthermore, before lifting...The counterweight 210 can slide to one side on the guide rail 209. After sliding, the counterweight 210 improves the stability of the grouting machine body 1 during the lifting process. After the counterweight 210 slides, the rotating rod 212 can drive the lead screw 211 to rotate, causing the lead screw 211 to abut against the guide rail 209, thus improving the stability of the slid counterweight 210.

[0024] As a technical optimization of this utility model, the grouting machine body 1 is provided with a winding structure 4. The winding structure 4 includes a mounting plate 401 fixedly connected to the grouting machine body 1. A winding shaft 402 is rotatably connected to the mounting plate 401. A connecting rod 403 is fixedly connected to the mounting plate 401. Two connecting discs 404 are fixedly connected to the connecting rod 403. A threaded post 405 is fixedly connected to the winding shaft 402. A guide ring 406 is fixedly connected to one of the connecting discs 404. The guide ring 406 is slidably connected to... A slider 407 is provided, and a guide block 408 is fixedly connected to the slider 407. The guide block 408 is slidably connected to a guide ring 406. A knob 409 is threadedly connected to the slider 407, and the knob 409 abuts against the guide ring 406. A clamping block 410 is slidably connected to the slider 407, and a sliding rod 411 is fixedly connected to the clamping block 410. The sliding rod 411 is slidably connected to the slider 407. A spring 413 is fixedly connected between the clamping block 410 and the slider 407. A pull rod 412 is fixedly connected to the sliding rod 411. The installation... A second motor 414 is mounted on plate 401. The winding shaft 402 is fixedly connected to the output shaft of the second motor 414. When the injection pipe needs to be wound up, the threaded part of the pipe is threaded into the threaded post 405. Then, by starting the second motor 414, the output shaft of the second motor 414 rotates, driving the winding shaft 402 to rotate. When the winding shaft 402 rotates, it winds the pipe between the two connecting discs 404. After winding is completed, the position of the slider 407 can be adjusted according to the position of the other end of the pipe, so that the slider 407 is on the guide ring 406. Sliding: When the slide reaches a certain position, rotate knob 409 to press it against guide ring 406, fixing slider 407. Then, pull rod 412, which will drive clamp 410 to slide via slide rod 411. When clamp 410 slides, spring 413 contracts. Then, place the end of the pipe between clamp 410 and slider 407. Then release pull rod 412, so that clamp 410 fixes the end of pipe under the action of spring 413. At this time, the pipe is wound up, which facilitates the winding and storage of the injection pipe.

[0025] In use, when the grouting machine body 1 injects mortar into the karst cave under the road, the mortar enters the sealed chamber from the hopper. Driven by the screw, the mortar moves forward continuously in the sealed chamber, constantly squeezing and pushing the mortar out. As the screw rotates, the mortar is pushed along the spiral channel. During this process, the chamber volume gradually decreases, and the mortar is squeezed and pressurized. Finally, it is injected into the karst cave under the road through the conveying pipe under high pressure, filling the karst cave space and enhancing the stability of the road foundation. When it is necessary to add mortar to the hopper on the grouting machine body 1, the bucket containing the mortar is placed between the two clamping rods 205. Then, the second hydraulic rod 208 is activated. When the extension end of the second hydraulic rod 208 retracts, it drives the guide plate 207 to slide. When the guide plate 207 slides, it drives the clamping rod 205 to slide. 5. Sliding allows clamping rod 205 to engage with another fixedly connected clamping rod 205 to clamp and fix the bucket. The rubber pad 206 on clamping rod 205 increases friction, improving the clamping effect. After clamping, the first hydraulic rod 201 is activated. When the telescopic end of the first hydraulic rod 201 extends, it drives the lifting plate 202 to move upward. When the lifting plate 202 moves upward, it drives the guide rod 213 to slide and connect with the grouting machine body 1. The guide rod 213 makes the sliding of the lifting plate 202 more stable. The lifting plate 202 drives the mounting box 203 to move upward. The mounting box 203 drives the bucket to move upward through the adjusting rod 204. When the adjusting rod 204 rises to a certain height, the first motor 304 is activated. When the output shaft of the first motor 304 rotates, it drives... The worm gear 303 rotates, which in turn drives the worm wheel 302 to rotate. The worm wheel 302 then drives the adjusting shaft 301 to rotate, which in turn drives the adjusting rod 204 to rotate. This causes the adjusting rod 204 to continuously rotate the bucket, thus automatically pouring the slurry into the hopper of the grouting machine body 1. After the height of the bucket is adjusted by the lifting plate 202, the bucket rotates to automatically pour the slurry into the hopper, reducing the difficulty of adding slurry to the hopper of the grouting machine body 1. Simultaneously, before lifting, the counterweight 210 can slide to one side on the guide rail 209. After sliding, the counterweight 210 improves the stability of the grouting machine body 1 during the lifting process. After the counterweight 210 slides, the rotating rod 212 drives the lead screw 211 to rotate, causing the lead screw 211 to contact the guide rail 209. To ensure the stability of the sliding counterweight 210, when the injection pipe needs to be wound up, the threaded part of the pipe is threaded into the threaded post 405. Then, by starting the second motor 414, the output shaft of the second motor 414 rotates, driving the winding shaft 402 to rotate. When the winding shaft 402 rotates, it winds the pipe between the two connecting discs 404. After winding, the position of the slider 407 can be adjusted according to the position of the other end of the pipe, so that the slider 407 slides on the guide ring 406. When it slides to a certain position, the knob 409 is rotated to make the knob 409 abut against the guide ring 406 to fix the slider 407. Then, by pulling the pull rod 412, the pull rod 412 will drive the clamp 410 to slide through the slide rod 411.When the clamp 410 slides, the spring 413 contracts, then the end of the pipe is placed between the clamp 410 and the slider 407. Then, the pull rod 412 is released, allowing the clamp 410 to fix the end of the pipe under the action of the spring 413. This completes the pipe winding process, facilitating the winding and storage of the injection pipe.
