Description

TECHNICAL FIELD

[0001] The present application mainly relates to the technical field of slope support construction, in particular to a concrete spraying construction equipment for slope support. BACKGROUND

[0002] In the field of civil engineering, slope support is a key process to ensure the stability of slope structures such as mountains and cuts. Among them, the concrete spraying technology is widely used in various slope reinforcement projects due to its convenient construction, high support strength, and adaptability to complex terrain. The technology controls the concrete spraying head through a mechanical arm, sprays premixed concrete at high speed to the slope surface, and forms a solid support layer. However, in the actual construction process, the spraying of concrete inevitably accompanies the problems of material waste and environmental pollution, and how to realize efficient and environmentally friendly spraying construction has become the focus of the industry.

[0003] At present, the traditional slope support concrete spraying equipment mainly focuses on the conveying and spraying functions of concrete, and lacks effective solutions to the problem of material waste during spraying. Specifically, during spraying, part of the concrete will rebound and fall from the slope surface due to the rebound effect, and another part will disperse into the air due to the scattering effect when exiting. The existing equipment usually does not configure a special recycling mechanism, resulting in the direct scattering of these concrete in the construction site, not only causing serious material waste and increasing construction cost, but also causing dust pollution, affecting the working environment and personnel health. In addition, some experimental recycling designs have defects such as complex structure, low recycling efficiency, easy to block, poor linkage with spraying operation, etc., which are difficult to meet the requirements of actual engineering for efficiency and reliability.

[0004] Therefore, it is urgent to develop a new type of concrete spraying construction equipment for slope support, which realizes efficient and automatic recycling of scattered and rebounded concrete, while ensuring smooth recycling process and stable operation of the equipment, so as to achieve the purpose of saving materials, protecting the environment, and improving the comprehensive construction benefit.

[0027] It should be noted that, in this embodiment, when the rebound concrete recycling device 30 is working, the rebounded concrete falls onto the conveyor belt 32 and the water spraying component 33. The water spraying component 33 sprays water mist to prevent the concrete from sticking together, and at the same time, the force of the water mist pushes the concrete received on the water spraying component 33 into the conveyor belt 32. The conveyor belt 32 continues to work to move the recycled concrete to the scraper recycling component 34, and the scraper recycling component 34 performs centralized suction of the recycled concrete. Furthermore, when the conveyor belt 32 is working, the stepper motor 325 drives the end drive wheel 321 to rotate.

Furthermore, when the water spraying component 33 is working, the receiving plate 331 receives the concrete, and the second water source pipe 335 can be connected to the water supply system on the concrete spraying vehicle. After the water supply system is turned on, the water flows through the second water source pipe 335 and the spray pipe 332 and is sprayed out through the spray nozzle 333. The water mist sprayed out through the spray nozzles 333 on both sides of the spray pipe 332 wets and propels the concrete on both sides of the spray pipe 332. The water mist sprayed from the top nozzle 333 of the water spray pipe 332 is blocked by the water baffle 334 and sprayed around the water baffle 334 to wet and push the concrete at the top of the water spray pipe 332. Furthermore, when the scraping and recycling component 34 is working, the suction pipe 344 can be connected to the negative pressure suction system on the concrete spraying vehicle body. The U-shaped scraper 342 continuously scrapes the concrete on the belt 323. After the negative pressure suction system is turned on, the suction pipe 344 generates suction, and the concrete moves along the U-shaped scraper 342 and is recycled through the recycling box 343 and the suction pipe 344. Furthermore, when the dilution component 35 is working, the third water supply pipe 353 can be connected to the water supply system on the concrete spraying vehicle. After the water supply system is turned on, water flows through the third water supply pipe 353, the diversion pipe 352 and the spray box 351 and is sprayed out to dilute the concrete and effectively prevent the concrete from sticking and clogging the pipe. Furthermore, when the brushing component 36 is working, the first gear ring 3643 and the second gear ring 3645 rotate with the rotating cover 21. The first gear ring 3643 drives the first brushing wheel 362 to rotate through the second gear 3642 and the first gear 3641, and the second gear ring 3645 drives the second brushing wheel 363 to rotate through the third gear 3644.

[0028] The working principle of this invention is as follows: The robotic arm 10 can be mounted on the concrete spraying vehicle body. The concrete spraying head 12 can be connected to the concrete supply system inside the concrete spraying vehicle body through a pipeline. After the concrete mixer truck unloads the concrete into the feed end of the concrete supply system, the concrete supply system is turned on. The concrete is sprayed out through the pipeline and the concrete spraying head 12 to realize the pouring of slope support concrete. During the pouring process, the robotic arm 10 drives the concrete spraying head 12 to adjust to the appropriate position and angle. Most of the concrete sprayed by the concrete spraying head 12 adheres to the slope, while some concrete is scattered into the air when it is sprayed by the concrete spraying head 12, and some concrete fails to adhere effectively and bounces and falls. The scattered concrete recycling device 20 recycles the scattered concrete, and the rebound concrete recycling device 30 recycles the rebounding concrete. When the scattering concrete recycling device 20 is working, the scattered concrete continuously adheres to the rotating hood 21. The scraper 22 can continuously scrape and collect the concrete adhering to the rotating hood 21. The water flushing component 23 can flush the concrete accumulated in the scraper 22 to the rebound concrete recycling device 30 for subsequent recycling. When the rotating cover 21 is working, the actuator of the power motor 213 drives the funnel cover 211 to rotate through the power gear 214 and the toothed ring 212; When the scraper 22 is working, the concrete on the inner wall of the rotating cover 21 is scraped up by the blade plate 222, blocked by the storage plate 223, and stored between the base plate 221 and the storage plate 223. When the water flushing component 23 is working, the first water source pipe 232 can be connected to the water supply system on the concrete spraying vehicle body. When the water supply system is turned on, the water flows through the first water source pipe 232 and the flushing pipe 231 and then flows out to flush the concrete accumulated between the base plate 221 and the storage plate 223. The flushed concrete falls into the conveyor belt 32. When the rebound concrete recycling device 30 is working, the rebounded concrete falls onto the conveyor belt 32 and the water spraying component 33. The water spraying component 33 sprays water mist to prevent the concrete from sticking and pushes the concrete on the water spraying component 33 into the conveyor belt 32 through the force of the water mist. The conveyor belt 32 continues to work to move the recycled concrete to the scraper recycling component 34. The scraper recycling component 34 performs centralized suction of the recycled concrete. When the conveyor belt 32 is working, the stepper motor 325 drives the end drive wheel 321 to rotate. The end drive wheel 321 drives other drive wheels 321 to rotate through the shaft and universal joint 324. The drive wheel 321 and the driven wheel 322 cooperate to drive the belt body 323 to move. When the water spraying component 33 is working, the receiving plate 331 receives the concrete, and the second water source pipe 335 can be connected to the water supply system on the concrete spraying vehicle. After the water supply system is turned on, the water flows through the second water source pipe 335 and the spray pipe 332 and is sprayed out through the spray nozzle 333. The water mist sprayed out through the spray nozzles 333 on both sides of the spray pipe 332 wets and pushes the concrete on both sides of the spray pipe 332. The water mist sprayed from the top nozzle 333 of the water spray pipe 332 is blocked by the water baffle 334 and sprayed around the water baffle 334 to wet and push the concrete at the top of the water spray pipe 332. When the scraping and recycling component 34 is working, the suction pipe 344 can be connected to the negative pressure suction system on the concrete spraying vehicle body. The U-shaped scraper 342 continuously scrapes the concrete on the belt 323. After the negative pressure suction system is turned on, the suction pipe 344 generates suction, and the concrete moves along the U-shaped scraper 342 and is recycled through the recycling box 343 and the suction pipe 344. When the dilution component 35 is working, the third water supply pipe 353 can be connected to the water supply system on the concrete spraying vehicle. After the water supply system is turned on, water flows through the third water supply pipe 353, the diversion pipe 352 and the spray box 351 and is sprayed out to dilute the concrete and effectively prevent the concrete from sticking and clogging the pipe. When the brushing component 36 is working, the first gear ring 3643 and the second gear ring 3645 rotate with the rotating cover 21. The first gear ring 3643 drives the first brushing wheel 362 to rotate through the second gear 3642 and the first gear 3641, and the second gear ring 3645 drives the second brushing wheel 363 to rotate through the third gear 3644. The first brushing wheel 362 and the second brushing wheel 363 rotate simultaneously, brushing the concrete on the belt 323 and gathering the concrete from both sides of the belt 323 towards the middle to facilitate subsequent recycling.
