Abstract
Description
Technical Field
[0001] This invention relates to the field of water conservancy engineering construction equipment technology, specifically to an integrated device for dredging and lining water channels. Background Technology
[0002] As a core infrastructure of water conservancy projects, irrigation canals undertake important functions such as agricultural irrigation, water resource transportation, and flood control and drainage. The construction quality and efficiency of canals directly affect the overall benefits of water conservancy projects. Traditional canal construction generally adopts a "segmented" operation mode, requiring the sequential deployment of excavators, manual repair teams, lining machines, and other equipment and personnel, which presents several prominent problems: First, the construction process is disjointed and inefficient. In traditional processes, excavation, trimming, and lining are independent procedures. Frequent equipment transfers and site cleanups are required between these procedures, resulting in long gaps between them and an inability to form a continuous workflow. This leads to a significant extension of the construction cycle, especially for long-distance canals, where the coordination costs for segmented construction are extremely high. Secondly, the contour accuracy is insufficient, and the quality is difficult to control. Existing excavation equipment can only cut soil and lacks dedicated trimming parts. After excavation, the slope of the canal is uneven and the bottom of the canal is uneven. It is necessary to rely on manual labor to use tools such as shovels and scrapers for secondary trimming. This is not only labor-intensive, but also has large human operation errors, making it difficult to accurately meet the design contour requirements, which in turn affects the flatness and sealing of the subsequent lining. Third, the lining has poor stability and many surface defects. Traditional lining devices lack a stable guiding structure, and are easily affected by the flatness of the ground when moving, causing vibrations. This leads to the displacement of the lining mold, and after the concrete is poured, defects such as misalignment and unevenness appear on the surface, requiring additional manpower for repairs and increasing construction costs. Fourth, the equipment has poor adaptability and is limited to certain scenarios. The excavation depth of existing construction equipment is mostly fixed, without flexible height adjustment components. It cannot be adapted to different ground elevations or different canal design depths, making it difficult to meet diverse construction needs and resulting in poor versatility. Fifth, the transportation of excavated soil is cumbersome and costly. Excavated soil requires separate transportation equipment such as dump trucks for transport, which not only increases equipment investment but also easily causes congestion at the construction site, affecting the construction progress, and also increases fuel consumption and labor coordination costs.
[0003] With the development of large-scale and standardized water conservancy projects, the demand for "efficient, precise, and integrated" construction equipment is becoming increasingly urgent. The traditional segmented construction mode can no longer meet the construction requirements of modern water conservancy projects. There is an urgent need for an integrated device that integrates the functions of the entire process of "excavation-transfer-repair-lining" to solve many of the shortcomings of existing technologies. Summary of the Invention
[0004] The purpose of this invention is to provide an integrated device for excavating and lining water channels to solve the problems mentioned in the background art. Through the integrated design of "overall traction + integrated function + precise control + stable guidance", it realizes continuous operation of water channel construction, ensures the accuracy of contour trimming and the flatness of the lining surface, flexibly adapts to different terrains and design requirements, and integrates earthwork transportation function to reduce additional equipment investment. Ultimately, it aims to improve construction efficiency, ensure project quality and reduce construction costs.
[0005] To achieve the above objectives, the present invention provides the following technical solution: an integrated device for excavating and lining a canal, comprising an overall drive unit, an excavation device, and a lining device. The overall drive unit is based on a tracked tractor as its core power source. A mounting base is welded to the rear of the tracked tractor, and a limit rod and a lifting hydraulic rod are provided on the mounting base. The excavation device includes a mounting arm, a drive arm, a drive gear, a fixed ring, a rotating ring, a bucket, a belt conveyor, a rotary drilling rig, and a shaping mold. The lining device includes a steel cable, a lining mold, rollers, and a track. The overall drive unit, the excavation device, and the lining device work together to achieve integrated continuous operation of canal excavation, transportation, shaping, and lining.
[0006] Preferably, one end of the mounting arm is hinged to the mounting base and can rotate around the hinge point. One end of the lifting hydraulic rod is connected to the mounting base via a pin, and the other end is connected to the middle of the mounting arm for adjusting the height of the mounting arm. The limiting rod is welded to the mounting base and located below the mounting arm to limit excessive rotation of the mounting arm and ensure height adjustment accuracy.
[0007] Preferably, one end of the drive arm is welded to the mounting arm, and the other end is welded to the fixed ring. A triangular bracket is also welded between the drive arm and the fixed ring. The three points of the triangular bracket are fixedly connected to the drive arm and the fixed ring respectively, which enhances the structural stability of the fixed ring. The rotating ring is fitted on the outside of the fixed ring and can rotate freely around the fixed ring. The outer side of the rotating ring is uniformly welded with force transmission teeth along the circumferential direction. The force transmission teeth mesh with the drive gear. The drive gear is fixedly installed on the drive arm through the bracket.
[0008] Preferably, the bucket is fixedly installed between two oppositely arranged rotating rings by bolts, and rotates synchronously with the rotating rings to achieve soil cutting. The belt conveyor is installed on the triangular bracket by a bracket and is located below the bucket. It is used to receive the soil that falls when the bucket rotates to the highest point and transport the soil to a designated area on the ground, realizing integrated soil transfer.
[0009] Preferably, the excavation device further includes a transmission gear, a universal joint, and a linkage arm. The transmission gear meshes with the force transmission gear. One end of the universal joint is connected to the transmission gear, and the other end is connected to the rotary drilling ruler. The inclination angle of the rotary drilling ruler is adapted to the design angle of the canal slope, and it can rotate and cut in close to the slope. One end of the linkage arm is hinged to the mounting arm, and the other end is welded to the shaping mold. The bottom of the shaping mold is a shape that matches the cross-section of the canal, and it can be fitted to the contour of the canal body after excavation for secondary shaping.
[0010] Preferably, the lining mold is fixedly connected to the shaping mold by steel cable and can move synchronously with the shaping mold. The top of the lining mold has an inlet for injecting concrete into the mold. Multiple rollers are symmetrically installed at the bottom of the lining mold by a bracket. The track is made of steel plate and is pre-laid on the ground of the construction route. The rollers slide in cooperation with the track to limit the movement trajectory of the lining mold and avoid shaking during the lining process.
[0011] Preferably, the excavation device further includes a fixed arm, one end of which is welded and fixed to the mounting arm, and the other end is connected to the drive arm to form a triangular stable support structure, which further enhances the overall load-bearing capacity and operational stability of the excavation device, and ensures that the equipment does not deform or shift during earthwork excavation and contour trimming.
[0012] Preferably, the travel speed of the tracked tractor is matched with the cutting speed of the excavation device and the moving speed of the lining device. Through the traction of the tracked tractor, the excavation, transportation, and trimming actions of the excavation device are seamlessly connected with the concrete pouring action of the lining device, eliminating the need for segmented construction and greatly improving the efficiency and quality of canal construction.
[0013] This invention provides an integrated device for dredging and lining water channels. It has the following beneficial effects: 1. This invention enables integrated continuous operation, significantly improving construction efficiency. Using a tracked tractor as the core traction mechanism, this invention integrates four major functions: excavation, transportation, trimming, and lining. It eliminates the need for segmented construction and equipment transfer, ensuring seamless workflow and increasing construction efficiency by over 60% compared to traditional methods. For long-distance canal construction, it can shorten the construction cycle by approximately 50%. 2. This invention uses the linkage of rotary drilling ruler and shaping mold for trimming. The rotary drilling ruler rotates and cuts the slope, and the shaping mold scrapes it flat for a second time. The slope error of the water channel is ≤±1° and the flatness error of the channel bottom is ≤±3mm. It accurately meets the design requirements, avoids the errors and defects of manual trimming, and improves the sealing and stability of subsequent lining. 3. The lining of this invention is stable and flat with excellent surface quality. The track and rollers form a stable guiding structure, which restricts the movement trajectory of the lining mold, effectively avoiding shaking and displacement. The lining surface is smooth and flat, without defects such as misalignment, unevenness, etc., requiring no subsequent repairs, and the project qualification rate is over 98%. 4. This invention is highly adaptable and flexible, with strong versatility. The lifting hydraulic rod and the limiting rod work together to flexibly adjust the excavation depth (0.5-3m), adapting to different ground elevations and the design depth of the canal; the shaping mold and lining mold can be replaced according to the cross-sectional shape of the canal (rectangular, trapezoidal), meeting diverse construction needs, and its versatility is significantly better than traditional fixed equipment; 5. This invention integrates earthwork transportation, reducing construction costs. The belt conveyor directly receives and transports earthwork, eliminating the need for additional dump trucks and reducing equipment investment costs by more than 30%. Simultaneously, it avoids construction site congestion, reduces labor coordination and fuel consumption costs, and significantly improves construction economics. 6. The invention features a stable and reliable structure, adapting to complex terrain. The fixed arm and triangular bracket form multiple stable supports, ensuring that the equipment remains undeformed and unshifted during excavation; the tracked tractor has strong off-road performance, adapting to the construction needs of different terrains such as plains and hills, and has a wide range of applications. 7. This invention integrates excavation and lining devices by using a tracked tractor to pull the entire equipment, transforming traditional segmented operations into continuous operations. This eliminates the need for frequent equipment transfers, significantly simplifying the construction process. The combination of lifting hydraulic rods and limit rods allows for flexible adjustment of the excavation device height, making it more adaptable to various terrains and canal design depths compared to fixed-height equipment, thus offering greater versatility. The rotary cutting ruler conforms to the slope for cutting, and the shaping mold undergoes secondary adjustments, avoiding human error and ensuring the canal contour accurately meets design requirements. The stable guidance of the track and rollers effectively reduces vibration during lining mold movement, resulting in a smooth and flat concrete lining surface. The belt conveyor integrates earthwork transportation, eliminating the need for additional dump trucks and reducing equipment investment and construction costs. Attached Figure Description

[0018] Example 1 A preferred embodiment of the integrated dredging and lining device for water channels provided by the present invention is as follows: Figure 1-4 As shown: An integrated device for excavating and lining a canal includes an overall drive unit, an excavation device 2, and a lining device 3. The overall drive unit is based on a tracked tractor 1 as its core power source. The tracked tractor 1 has a mounting base 201 welded to its rear. The mounting base 201 is equipped with a limit rod 202 and a lifting hydraulic rod 203. The excavation device 2 includes a mounting arm 204, a drive arm 205, a drive gear 206, a fixed ring 209, a rotating ring 211, a bucket 212, a belt conveyor 213, a rotary drilling ruler 214, and a shaping mold 218. The lining device 3 includes a steel cable 301, a lining mold 302, rollers 304, and a track 305. The overall drive unit, the excavation device 2, and the lining device 3 work together to achieve integrated continuous operation of canal excavation, transportation, shaping, and lining.
[0019] One end of the mounting arm 204 is hinged to the mounting base 201 and can rotate around the hinge point. One end of the lifting hydraulic rod 203 is connected to the mounting base 201 via a pin, and the other end is connected to the middle of the mounting arm 204. It is used to adjust the height of the mounting arm 204. The limiting rod 202 is welded to the mounting base 201 and located below the mounting arm 204. It is used to limit the excessive rotation of the mounting arm 204 and ensure the accuracy of height adjustment.
[0020] One end of the drive arm 205 is welded to the mounting arm 204, and the other end is welded to the fixing ring 209. A triangular bracket 208 is also welded between the drive arm 205 and the fixing ring 209. The three points of the triangular bracket 208 are fixedly connected to the drive arm 205 and the fixing ring 209 respectively, which enhances the structural stability of the fixing ring 209. The rotating ring 211 is fitted on the outside of the fixing ring 209 and can rotate freely around the fixing ring 209. The outer side of the rotating ring 211 is uniformly welded with force transmission teeth 210 along the circumferential direction. The force transmission teeth 210 mesh with the drive gear 206. The drive gear 206 is fixedly installed on the drive arm 205 through the bracket.
[0021] The bucket 212 is fixedly installed between two oppositely arranged rotating rings 211 by bolts. It rotates synchronously with the rotating rings 211 to achieve soil cutting. The belt conveyor 213 is installed on the triangular bracket 208 by a bracket and is located below the bucket 212. It is used to receive the soil that falls when the bucket 212 rotates to the highest point and transport the soil to the designated area on the ground to achieve integrated soil transfer.
[0022] Example 2 Please see Figures 1-4 Furthermore, based on Example 1, the excavation device 2 further includes a transmission gear 215, a universal joint 216, and a linkage arm 217. The transmission gear 215 meshes with the force transmission gear 210. One end of the universal joint 216 is connected to the transmission gear 215, and the other end is connected to the rotary drilling ruler 214. The inclination angle of the rotary drilling ruler 214 is adapted to the design angle of the canal slope, and it can rotate and cut in close contact with the slope. One end of the linkage arm 217 is hinged to the mounting arm 204, and the other end is welded to the shaping mold 218. The bottom of the shaping mold 218 is a shape that matches the cross-section of the canal, and it can be fitted to the contour of the canal body after excavation for secondary trimming.
[0023] The lining mold 302 is fixedly connected to the shaping mold 218 by a steel cable 301 and can move synchronously with the shaping mold 218. The top of the lining mold 302 has an inlet 303 for injecting concrete into the mold. Multiple rollers 304 are symmetrically installed on the bottom of the lining mold 302 by a bracket. The track 305 is made of steel plate and is pre-laid on the ground of the construction route. The rollers 304 and the track 305 cooperate to slide, restricting the movement trajectory of the lining mold 302 and avoiding shaking during the lining process.
[0024] The excavation device 2 also includes a fixed arm 207. One end of the fixed arm 207 is welded and fixed to the mounting arm 204, and the other end is connected to the drive arm 205 to form a triangular stable support structure, which further enhances the overall load-bearing capacity and operational stability of the excavation device 2, and ensures that the equipment is free from deformation and displacement during earthwork excavation and contour trimming.
[0025] The travel speed of the tracked tractor 1 is matched with the cutting speed of the excavation device 2 and the moving speed of the lining device 3. Through the traction of the tracked tractor 1, the excavation, transportation and trimming actions of the excavation device 2 are seamlessly connected with the concrete pouring action of the lining device 3, eliminating the need for segmented construction and greatly improving the efficiency and quality of canal construction.
[0026] During operation, the tracked tractor 1 is driven to the starting position of the construction. Based on the ground elevation and the designed depth of the canal, the lifting hydraulic rod 203 is activated to push the mounting arm 204 to rotate around the mounting base 201, adjusting the overall height of the excavation device 2 so that the cutting trajectory of the bucket 212 and the contact angle of the rotary excavator 214 conform to the designed excavation profile. The limit rod 202 limits the rotation angle of the mounting arm 204 in real time to avoid over-adjustment that could lead to excessive excavation depth, ensuring the accuracy of height adjustment. At the same time, the track 305 is pre-laid along the construction route, and the rollers 304 at the bottom of the lining mold 302 are placed on the track 305 to complete the equipment positioning.
[0027] Start the tracked tractor 1 and move forward slowly at a preset speed (0.5-1m / min). At the same time, start the drive gear 206. The drive gear 206 drives the meshing transmission gear 210 to rotate, which in turn drives the rotating ring 211 to rotate around the fixed ring 209. The rotating ring 211 synchronously drives the bucket 212 to rotate. The blade of the bucket 212 cuts into the soil and cuts the soil. When the bucket 212 rotates to the highest point, the soil falls onto the belt conveyor 213 below under the action of gravity. The belt conveyor 213 runs synchronously and transports the soil to the designated material storage area on the ground, realizing the integrated transfer of soil without the need for additional dump trucks and avoiding congestion at the construction site.
[0028] During the rotation of the rotating ring 211, the power transmission gear 210 synchronously drives the meshing transmission gear 215 to rotate; the transmission gear 215 transmits power to the rotary drilling ruler 214 through the universal joint 216, so that the rotary drilling ruler 214 fits against the canal slope and rotates at high speed to cut and smooth the uneven parts of the slope, ensuring that the slope is uniform; at the same time, the shaping mold 218, under the traction of the linkage arm 217, moves forward synchronously with the mounting arm 204 and the tracked tractor 1, and its bottom fits against the excavated canal bottom and slope to perform secondary shaping of the contour, completely eliminating the remaining protrusions and depressions, ensuring that the contour of the canal accurately meets the design requirements, and laying a good foundation for subsequent lining.
[0029] After the outline is trimmed, concrete is continuously injected into the mold through the inlet 303 at the top of the lining mold 302, and the concrete is initially formed inside the mold. Under the traction of the steel cable 301, the lining mold 302 moves forward synchronously with the trimming mold 218 and the tracked tractor 1. During the movement, the roller 304 slides smoothly along the track 305, strictly limiting the movement trajectory of the lining mold 302 to avoid shaking or deviation. Under the constraint of the mold, the concrete gradually solidifies and forms a smooth and flat water channel lining surface, achieving a seamless connection between excavation and lining without the need for segmented construction.
[0030] In summary, the present invention possesses: 1. Overall traction and height adjustment coordination: Taking the tracked tractor 1 as the core, the lifting hydraulic rod 203 and the limiting rod 202 work together to adjust the height of the mounting arm 204, adapting to different terrains and water ditch depths, and solving the problem of fixed height of existing equipment; 2. Integrated excavation, transportation and finishing: The excavator bucket 212 rotates for excavation, the belt conveyor 213 integrates the transportation of soil, and the rotary drilling rig 214 and the finishing mold 218 work together to finish the soil, realizing continuous operation of multiple processes without the need for segmented construction. 3. Stable lining guidance: The track 305 and roller 304 work together to limit the movement trajectory of the lining mold 302, avoid vibration, ensure the flatness of the lining surface, and solve the problem of poor stability of traditional lining machines; 4. Power transmission: The power transmission path of drive gear 206 → power transmission gear 210 → rotating ring 211 synchronously drives bucket 212 and transmission gear 215, so that excavation and trimming actions are coordinated and the operation is improved.
