Description

Technical Field

[0001] The present application relates to an ash silo dredging device capable of accurately locating an operation position. Background Art

[0002] The ash outlet of the ash bin of a thermal power plant is often severely blocked due to the accumulation of compacted layers. At present, manual cleaning still dominates the solution to this problem. This method relies on professional cleaning personnel to go deep into the ash bin environment and use manual tools or auxiliary equipment to physically break and clean the dense compacted layer formed at the ash outlet and its surroundings.

Second, manual cleaning of the compacted layer cannot ensure that the destruction point is located at the weakest point of the compacted layer. There is a certain possibility that the compacted layer structure may not be completely destroyed, which will further deepen the compaction situation and make the ash outlet blockage state more serious.

[0024] See also Figures 1 to 3The present embodiment relates to an ash bin dredging device capable of accurately locating an operation position, comprising a multi-stage lifting rod 3 installed at an upper opening of an ash bin 1, a laser modeling assembly 2 fixedly connected to the multi-stage lifting rod 3, a drilling rig lifting platform 5 arranged near the plane where the ash outlet of the ash bin 1 is located, and a jet grouting drill 4 installed on the drilling rig lifting platform 5, wherein the jet grouting drill 4 comprises a jet grouting drill bit 401, an operation angle adjustment mechanism for fine-tuning the operation angle, and an operation position adjustment mechanism for fine-tuning the operation position.

[0025] First, after debugging the laser modeling component 2, the internal model of the current ash storehouse 1 is scanned and identified by the laser modeling component 2. Figure 2 As shown, the laser modeling component 2 is mainly composed of a 3D laser scanner 205, a rotating motor 203, a coupling 204, a scanner frame 202, and a scanner housing 201. The 3D laser scanner 205 is connected to the rotating motor 203 by a coupling 204, and the rotating motor is installed on the scanner frame 202 and protected by the scanner housing 201. During operation, the 3D laser scanner 205 is started first, and the laser modeling component 2 is controlled to lower its height through the multi-stage lifting rod 3. At the same time, the 3D laser scanner 205 starts to rotate under the drive of the rotating motor 203. Under the longitudinal and circumferential movement, the 3D laser scanner 205 can obtain the complete internal shape of the ash bin and the position of the compaction layer. According to the data obtained by the 3D laser scanner 205, the accurate position of the operation point can be obtained.

[0026] Then, according to the position of the working point identified by the laser modeling component 2, the relative position of the drilling rig lifting platform 5 and the jet grouting drilling rig 4 is adjusted. Before the operation, the height of the drilling rig lifting platform 5 is first adjusted and moved to a suitable position, and then the working angle of the jet grouting drilling rig 4 is adjusted and its working position is fine-tuned. Figure 3 As shown, the jet grouting drill 4 is composed of a jet grouting drill bit 401 , an extension rod 402 , a hydraulic lifting rod 403 , a drill bit mounting frame 404 , a hydraulic cylinder driving motor 405 , a base 406 , and a moving motor 407 .

[0027] The working angle adjustment mechanism includes a drill mounting frame 404, a hydraulic cylinder driving motor 405, and a base 406. The drill mounting frame 404 is hinged with the base 406. One end of the hydraulic lifting rod 403 is fixed to the base 406, and the other end is connected to the drill mounting frame 404. The working position adjustment mechanism includes a mobile motor 407 connected to the jet grouting drill 4 and the drilling rig lifting platform 5. By controlling the rotation of the mobile motor 407, the jet grouting drill 4 can be moved horizontally in a small range on the working surface as a whole, and the working position can be fine-tuned.

[0028] In this embodiment, the jet drill bit 401, the extension rod 402 and the drill bit mounting frame 404 are fixedly connected and are an integral unit when in use. The jet drill bit 401 is provided with a jet flow channel to generate a jet flow to form an air knife. Through the fixed-point destruction of the drill bit and the air knife generated by the jet flow, the hardened layer can be effectively destroyed. The drill bit mounting frame 404 is connected to the base 406 by a hinge, and one end of the hydraulic lifting rod 403 is fixed to the base 406 and the other end is connected to the drill bit mounting frame 404. The operating angle of the jet drill 4 can be adjusted by adjusting the extension length of the hydraulic lifting rod 403, and the small-range lateral movement of the drill rig as a whole on the working surface can be achieved by controlling the rotation of the mobile motor 407, so as to achieve fine adjustment of the working position.

[0029] Finally, the jet grouting drill 401 is transported to the working position identified by the laser modeling component 2 using the extension rod 402 and the operation is started. During the operation, a hole is first opened at a suitable position on the ash bin 1, and then the height of the lifting platform 5 and the extension length of the hydraulic lifting rod 403 are adjusted. Next, the jet grouting drill 401 is moved close to the end working position using the extension rod 402. When the length of the extension rod 402 is close to the set parameter, the jet grouting drill 401 is started. At this time, the drill starts to rotate and sprays out a jet of jet outward. Through the fixed-point destruction of the hardened layer by the drill and the air knife generated by the airflow, the hardened layer at the corresponding position is effectively broken. By using the same method to destroy the hardened layers at the remaining located working points, all the hardened layers can be completely cleaned.

[0030] In other embodiments, the laser modeling component can be replaced by a radar scanning device, which constructs a three-dimensional model of the interior of the ash bin by emitting electromagnetic waves and receiving their reflected signals; or the laser modeling component can be replaced by an ultrasonic sensor array, which calculates the distance by measuring the time difference between the emission and reflection of the ultrasonic wave, and then constructs a three-dimensional model; or the laser modeling component can be replaced by a high-definition camera, which processes and analyzes the images captured by the camera through a machine vision algorithm; the jet grouting drill can be replaced by a high-pressure gas cannon, which implements a fixed-point airflow impact on the working point to break and collapse the compacted layer; the jet grouting drill can be replaced by chemical reagents, which use a long dropper to drip chemical corrosives on the compacted layer to cause holes on its surface, thereby reducing its strength and causing it to collapse on its own.

[0031] In the present application, the modeling component can realize the modeling of the interior of the ash silo. It is an important equipment for obtaining the ash silo environmental model. Under the joint action of the multi-stage lifting rod and the rotating motor, the modeling component scans the surface of the object by emitting a laser beam, collects the reflected signal to generate three-dimensional point cloud data, and then uses the algorithm to perform data processing, point cloud registration and surface reconstruction, and finally constructs a three-dimensional model of the object. This model provides the rotary jet drilling rig with an accurate view of the working environment and accurately calibrates the working position, so that the drill bit can accurately and efficiently destroy the weak areas of the compacted layer, thereby significantly improving the efficiency and accuracy of the ash silo dredging operation, and can realize all-round modeling of the interior of the ash silo and analysis of the position of the compacted layer, and provide reference coordinates for the working position and height of the rotary jet mechanism.

[0032] The drilling rig lifting platform is mainly used to adjust the relative height of the laser modeling component in the ash silo. By controlling the height and position of the drilling rig lifting platform and the operating angle and position of the jet grouting drill, the terminal operating point can be guaranteed to be in the best operating position. By adopting a multi-level lifting mechanism, the drilling rig lifting platform can flexibly cope with the complex and changeable operating environment of the ash silo, ensuring that the laser scanning equipment can penetrate deep into the ash silo and reach and scan deeper terrain areas. The equipment enables the modeling component to fully capture detailed terrain data inside the ash silo, including but not limited to key information such as the distribution of the compacted layer and the height change of the deposit.

[0033] The end of the jet jet mechanism is equipped with a jet jet drill, a well drilling drill and a jet jet channel, which are used to effectively destroy the hardened layer. The well drilling drill can perform fixed-point destruction on the hardened layer, and the high-pressure airflow ejected from the jet outlet of the jet jet channel can form an air knife. Through the fixed-point destruction of the drill bit and the air knife generated by the jet jet, further destruction is performed from the position of the hardened layer broken by the well drilling drill, so that the hardened layer collapses more effectively, and the hardened layer can be effectively destroyed.

[0034] The extension rod has been carefully designed and selected to ensure that it has sufficient structural strength to withstand the load during operation, while maintaining good flexibility for flexible deployment in complex ash storage environments. By using the appropriate extension rod length, the jet grouting drill can break through the original operation limitations, reach and effectively clean the relatively more remote hardened layer area, thereby significantly improving the efficiency and depth of the ash storage cleaning operation, reducing the need for manual intervention, and achieving more thorough and efficient ash storage maintenance.

[0035] The drill mounting bracket is used to install the jet grouting drill bit and the extension rod, providing a suitable mounting platform for both. This mounting bracket not only ensures that the jet grouting drill bit and the drill extension rod can be accurately docked and securely locked, but also can adjust the operating angle of the drill bit through the hydraulic lifting rod, thereby accurately controlling the specific operating position of the end of the drilling rig in a complex working environment.

[0036] The drilling rig lifting platform is mainly based on steel scaffolding, and its modular design ensures that the structure is stable and easy to adjust. The platform has a customized working platform specially reserved at the top, which is designed to carry the jet grouting rig and provide a safe and stable operating environment. By finely adjusting the height of each section of the scaffolding, the system can flexibly adapt to the height requirements of the jet grouting rig working platform under different working conditions, ensuring that the rig can be in the best working posture, thereby improving operating efficiency and accuracy.

[0037] Compared with the existing technology, this equipment has high reliability, low cost, can accurately locate the working position and does not require excessive manual operation, and has good applicability.

[0038] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
