Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering construction equipment technology, and in particular to a fully automatic slipform paver for water supply canals. Background Technology

[0002] Water supply canals are core infrastructure in water conservancy systems for water conveyance, farmland irrigation, and urban water supply and drainage. The quality of concrete pouring directly determines the canal's impermeability, stability, and service life. Currently, concrete construction of water supply canals mostly adopts traditional formwork support pouring or fixed slipform paving equipment. Traditional construction methods have obvious drawbacks: First, fixed slipform equipment has fixed mold sizes, which can only be adapted to the construction of a single specification of water supply canal. When constructing water supply canals with different widths and cross-sectional dimensions, the entire mold equipment needs to be replaced, resulting in poor adaptability, high construction costs, and low equipment versatility. Second, the assembly and disassembly of traditional formwork is cumbersome, resulting in low construction efficiency, a large amount of manual intervention, and difficulty in achieving fully automated continuous paving operations. Third, the poor sealing of the mold joints makes the poured canal prone to quality defects such as misalignment, gaps, and grout leakage, affecting the overall construction quality of the water supply canal.

[0003] Existing technologies lack a fully automatic slipform paver capable of rapidly and adaptively adjusting the channel forming width, possessing strong structural stability, and adaptable to the construction of various specifications of water supply channels. This fails to meet the diverse, efficient, and high-precision construction needs of current water conservancy projects. Therefore, this invention proposes a fully automatic slipform paver for water supply channels to address the deficiencies of the existing technologies. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art by proposing a fully automatic slipform paver for water supply channels.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A fully automatic slipform paver for water supply channels includes a slipform support base plate and a width-adaptive forming mold assembly;

[0007] The sliding mold support base plate is provided with guide grooves parallel to its own length direction, which provides precise guidance for the sliding adjustment of the forming structure and ensures the stability of the adjustment process. The width adaptive forming mold assembly includes two sets of channel-shaped forming mold frames and bidirectional adjusting screws. The two sets of channel-shaped forming mold frames are fixedly connected in parallel to the sliding mold support base plate, forming the main forming support structure of the equipment.

[0008] The bidirectional adjusting screw is fixedly connected to the sliding mold bearing base plate through a fixed seat in the middle, and the fixed seat is set at the midpoint of the bidirectional adjusting screw. The bidirectional adjusting screw adopts an integrated positive and negative thread screw structure. At the same time, the bidirectional adjusting screw is fixedly installed between two sets of channel-shaped forming mold frames through a support frame, which further improves the structural stability of the screw installation.

[0009] Two sets of adjusting frames are slidably connected between the two sets of channel-shaped forming mold frames. Each set of adjusting frames is connected to a bidirectional adjusting screw via a driving mechanism. Both sets of adjusting frames pass through guide grooves, and the bottom of both sets of adjusting frames is connected to an adjustable channel compartment. The bidirectional adjusting screw, in conjunction with the driving mechanism, drives the adjusting frames to slide, thereby achieving adaptive adjustment of the width of the adjustable channel compartment.

[0010] In the aforementioned fully automatic slipform paver for water supply channels, each set of adjustment frames is equipped with a sliding boss at its bottom. The sliding boss is embedded in the guide groove for sliding engagement, and is fixedly connected to the adjustable compartment of the channel body. Through the bottom limiting engagement of the guide groove and the sliding boss, the straightness of the adjustment frame and the adjustable compartment of the channel body is ensured during the adjustment process, preventing vertical displacement. At the same time, each set of channel-shaped forming mold frames has a limiting groove on its side wall, and each set of adjustment frames has a corresponding limiting slide on its side wall. The limiting slide is slidably connected to the limiting groove at the corresponding position, forming a side sliding limiting structure. This, together with the bottom guide groove and the sliding boss, constitutes a double-layer limiting and guiding structure, further limiting the horizontal displacement of the adjustment frame and significantly improving the stability and accuracy of the sliding adjustment process.

[0011] In the aforementioned fully automatic slipform paver for water supply canals, the pushing mechanism includes two symmetrically arranged adjusting nuts. The two adjusting nuts are respectively connected to the positive and negative tooth sections of the bidirectional adjusting screw. Two pushing seats are symmetrically fixedly installed on each set of adjusting frames. Two pushing connecting rods are symmetrically hinged on each adjusting nut. The end of the pushing connecting rod away from the adjusting nut is hinged to the corresponding pushing seat, forming a four-bar synchronous pushing structure to ensure uniform power transmission and good adjustment synchronization.

[0012] In the aforementioned fully automatic slipform paver for water supply channels, the adjustable channel section is composed of a left U-shaped half-section and a right U-shaped half-section that are inserted together. The left U-shaped half-section is inserted inside the right U-shaped half-section, and the overall width can be infinitely adjusted through the insertion telescopic structure to adapt to the forming requirements of water supply channels of different widths.

[0013] In the aforementioned fully automatic slipform paver for water supply channels, the left U-shaped half-compartment includes a left compartment bottom plate, a front upright plate, and a rear upright plate. A set of sliding bosses at the bottom of the adjustment frame are fixedly connected to the lower end of the left compartment bottom plate. The ends of the left compartment bottom plate, the front upright plate, and the rear upright plate are all fixedly installed with a left arc-shaped sealing plate, forming a closed molding structure for the left half-compartment.

[0014] In the aforementioned fully automatic slipform paver for water supply channels, the right-side U-shaped half-compartment includes a right-compartment bottom plate, a second front upright plate, and a second rear upright plate. The sliding boss at the bottom of another set of adjustment frames is fixedly connected to the lower end of the right-compartment bottom plate. The ends of the right-compartment bottom plate, the second front upright plate, and the second rear upright plate are all fixedly installed with a right-side arc-shaped sealing plate, which cooperates with the left-side arc-shaped sealing plate to achieve the closure and forming of the channel end.

[0015] In the aforementioned fully automatic slipform paver for water supply channels, both the left and right arc-shaped sealing plates are welded and fixed with annular lifting rings to facilitate the overall lifting, transportation, installation, and maintenance of the equipment. The left compartment bottom plate, the first front upright plate, and the first rear upright plate all share a U-shaped assembly slot, within which a connecting protrusion is fixedly installed. The right compartment bottom plate, the second front upright plate, and the second rear upright plate all have matching connecting grooves. The connecting protrusions and grooves vertically engage, significantly improving the sealing and structural stability of the U-shaped half-compartment insertion points on both sides, preventing grout leakage and deformation during the pouring process.

[0016] Compared with existing technologies, the beneficial effects of the present invention are as follows:

[0017] 1. This invention features a width-adaptive forming mold assembly. Through an integrated positive and negative thread bidirectional adjusting screw and a four-bar linkage mechanism, two sets of adjusting frames can be driven to slide relative to each other, thereby adjusting the left and right U-shaped half-compartments of the adjustable compartment of the channel body to achieve stepless adaptive adjustment of the forming width of the water supply channel. It can adapt to the construction of multiple specifications of water supply channels without changing the mold, greatly improving the versatility of the equipment and reducing the cost of construction equipment.

[0018] 2. This invention ensures precise and non-offset adjustment of the channel body through the limiting sliding cooperation of the guide groove and the sliding boss. Combined with the vertical locking structure of the plug-in protrusion and the plug-in groove, it improves the sealing and structural strength of the mold splicing position, effectively avoids problems such as grout leakage, channel body misalignment and deformation during concrete pouring, and significantly improves the forming quality of the water supply channel.

[0019] 3. The present invention has a high degree of overall structural integration, which can realize fully automatic continuous slipform paving operation, reduce manual intervention, simplify construction procedures, greatly improve the efficiency of concrete paving construction of water supply channels, and is suitable for large-scale, standardized water conservancy project construction scenarios.

[0020] 4. The present invention features an annular lifting ring on the arc-shaped sealing plate, which facilitates the lifting, transportation, installation, and daily inspection and maintenance of the equipment. The equipment is highly convenient to use, has a stable structure, and a long service life. Attached Figure Description

[0030] The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0031] Example 1

[0032] Reference Figure 1-4 A fully automatic slipform paver for water supply channels includes a slipform support base plate 1 and a width-adaptive forming mold assembly installed above the slipform support base plate 1. The slipform support base plate 1 serves as the support base of the entire machine and is integrally cut and formed from a high-strength steel plate. It has high overall flatness and strong load-bearing capacity, effectively bearing the pressure of concrete pouring and the weight of the equipment, and preventing deformation and bending of the base plate during paving operations. The slipform support base plate 1 has two symmetrically arranged guide grooves 101 parallel to its length. The guide grooves 101 are formed by milling, with smooth inner walls and high dimensional accuracy, which can provide precise linear guidance constraints for the upper sliding adjustment structure and effectively reduce sliding friction resistance.

[0033] The width-adaptive forming mold assembly includes two symmetrically arranged channel-shaped forming mold frames 2 and a bidirectional adjusting screw 3. The two sets of channel-shaped forming mold frames 2 are parallel and perpendicularly fixedly assembled on the sliding mold support base plate 1, forming a central assembly space to provide a stable installation foundation for the adjustment and transmission structures. The bidirectional adjusting screw 3 is an integrated positive and negative thread precision screw. A fixing seat 301 is fixedly assembled in the middle of the bidirectional adjusting screw 3. The fixing seat 301 is locked to the sliding mold support base plate 1 by bolts, realizing the centered positioning and installation of the bidirectional adjusting screw 3, ensuring that the lengths of the positive and negative thread sections on both sides of the bidirectional adjusting screw 3 are completely symmetrical, and ensuring the synchronicity and uniformity of subsequent bidirectional adjustments. Meanwhile, support frames 302 are installed at both ends of the bidirectional adjusting screw 3. The bottom end of the support frame 302 is fixedly connected to the upper end of the channel-shaped forming mold frame 2. The bidirectional adjusting screw 3 is supported by the support frames 302 at both ends, which effectively reduces the suspended span in the middle of the bidirectional adjusting screw 3, eliminates the problem of bending and transmission jamming of the bidirectional adjusting screw 3 under load, and greatly improves the operational stability and service life of the bidirectional adjusting screw 3.

[0034] Two sets of symmetrically distributed adjusting frames 6 are slidably assembled in the central space of the two sets of channel-shaped forming mold frames 2. Two sets of symmetrical pushing mechanisms 4 are matched and installed between the bidirectional adjusting screw 3 and the two sets of adjusting frames 6. The pushing mechanism 4 includes two adjusting nuts 401 that are respectively threaded into the positive and negative tooth sections of the bidirectional adjusting screw 3. Two pushing seats 402 are symmetrically fixed on the inner side wall of each set of adjusting frames 6. A pushing connecting rod 403 is hinged to the upper and lower end faces of each adjusting nut 401. The four pushing connecting rods 403 are symmetrically arranged, and the end of each pushing connecting rod 403 is hinged to the corresponding pushing seat 402, forming a symmetrical four-bar synchronous transmission structure. This structure can convert the rotational motion of the bidirectional adjusting screw 3 into the linear reciprocating motion of the adjusting frame 6, and the transmission force is uniform, which can effectively avoid the problems of unilateral force offset and jamming, and ensure the accuracy and synchronization of width adjustment.

[0035] To achieve high-precision limiting guidance, this embodiment adopts a double-layer bidirectional limiting structure. Each set of adjustment frames 6 has an integrally cast sliding boss 601 at its bottom. The outer dimensions of the sliding boss 601 precisely match the dimensions of the guide groove 101. The sliding boss 601 is embedded in the guide groove 101 for sliding cooperation, achieving vertical limiting and horizontal guidance of the bottom of the adjustment frame 6, effectively restricting the vertical jump and vertical offset of the adjustment frame 6. Simultaneously, each set of channel-shaped forming mold frames 2 has a rectangular limiting groove 201 on its inner sidewall. The limiting groove 201 extends along the length of the mold frame. Corresponding to the position of the limiting groove 201, the outer sidewall of each set of adjustment frames 6 has an integrally formed limiting slide 602. The limiting slide 602 slides and engages inside the limiting groove 201, forming a side horizontal limiting structure. With the dual limiting constraints of the bottom guide slide 101 and the side wall limiting slide 201, the movement trajectory of the adjustment frame 6 is locked in both vertical and horizontal directions, completely eliminating the offset, shaking and jamming phenomena during the adjustment process, and ensuring that the sliding adjustment is stable and accurate throughout the entire process.

[0036] The bottom ends of the two sets of adjustment frames 6 are fixedly connected to the adjustable channel chamber 5. The adjustable channel chamber 5 is a telescopic U-shaped forming cavity structure, which is adapted to the casting and forming requirements of the U-shaped cross section of the water supply channel. The adjustable channel chamber 5 is composed of a left U-shaped half chamber 501 and a right U-shaped half chamber 502 inserted and nested together. The left U-shaped half chamber 501 is slidably inserted into the right U-shaped half chamber 502. Through the relative telescopic sliding of the left and right half chambers, the stepless adaptive adjustment of the channel forming width can be realized, which can adapt to the construction of various conventional width specifications of water supply channels without changing the mold.

[0037] Example 2

[0038] Based on Example 1, this embodiment optimizes and refines the plug-in sealing structure, end sealing structure, and hoisting structure of the adjustable compartment of the channel.

[0039] Specifically, the left U-shaped half-compartment 501 is integrally welded together from the left compartment bottom plate 5011, the front upright plate 5012, the rear upright plate 5013, and the left arc-shaped sealing plate 5014, resulting in a strong overall structure that is not easily deformed. The sliding boss 601 at the bottom of the left adjustment frame 6 is welded and fixed to the upper surface of the left compartment bottom plate 5011, enabling synchronous movement between the left U-shaped half-compartment 501 and the left adjustment frame 6. The ends of the left compartment bottom plate 5011, the front upright plate 5012, and the rear upright plate 5013 are all welded and fixed to the left arc-shaped sealing plate 5014.

[0040] Correspondingly, the right-side U-shaped half-compartment 502 is formed by welding together the right compartment bottom plate 5021, the front upright plate 5022, the rear upright plate 5023, and the right-side arc-shaped sealing plate 5024. The sliding boss 601 at the bottom of the right-side adjustment frame 6 is fixedly connected to the upper end face of the right compartment bottom plate 5021 and slides synchronously with the right-side adjustment frame 6. The right-side arc-shaped sealing plate 5024 seals the end of the right-side plate and symmetrically cooperates with the left-side arc-shaped sealing plate 5014 to form a complete channel end forming structure, ensuring that the channel end has a regular arc and uniform dimensions after casting.

[0041] To completely solve the problem of grout leakage at the telescopic joint, this embodiment features a vertical locking and sealing structure. The inner sides of the left compartment bottom plate 5011, the first front upright plate 5012, and the first rear upright plate 5013 share a common U-shaped assembly groove 5015. An integral rubber insertion protrusion 5016 is embedded and fixed inside the U-shaped assembly groove 5015. The insertion protrusion 5016 is wear-resistant, elastic, and has strong sealing performance. Simultaneously, the inner sides of the right compartment bottom plate 5021, the second front upright plate 5022, and the second rear upright plate 5023 are correspondingly provided with vertically arranged insertion grooves 5025. The insertion grooves 5025 precisely match and vertically lock into place with the insertion protrusions 5016. Compared to traditional horizontal splicing structures, vertical interlocking structures can completely fit the joint gaps, preventing grout from seeping out from the expansion gaps during concrete pouring, thus fundamentally eliminating quality defects such as grout leakage, pitting, and honeycombing. At the same time, the interlocking structure can mutually restrain the lateral displacement of the left and right halves, further improving the overall structural rigidity of the mold and preventing the mold from bulging and deforming under pouring pressure.

[0042] In addition, to meet the needs of on-site transportation, installation, and maintenance, annular lifting rings 503 are welded and fixed to the outer end faces of both the left arc-shaped sealing plate 5014 and the right arc-shaped sealing plate 5024. The annular lifting rings 503 are formed by bending and welding round steel, with full welding reinforcement at the weld joints and no incomplete welding, resulting in excellent load-bearing capacity. When the equipment is disassembled, assembled, or transported as a whole, it can be directly lifted by the lifting rings in conjunction with the lifting equipment without additional binding and fixing. This makes operation convenient, ensures stable force distribution, effectively prevents the equipment from tilting or falling during lifting, improves construction safety, and facilitates daily disassembly, maintenance, and component replacement.

[0043] Example 3

[0044] The sliding formwork bearing base plate 1 serves as the overall bearing foundation for the equipment. Two sets of guide grooves 101 are opened parallel along the length direction on the plate to provide precise guidance and limit for the sliding adjustment structure.

[0045] The width-adaptive forming mold assembly includes two sets of channel-shaped forming mold frames 2 and a bidirectional adjusting screw 3. The two sets of channel-shaped forming mold frames 2 are fixedly mounted in parallel on the upper surface of the sliding mold support base plate 1, forming the forming support frame of the equipment. The bidirectional adjusting screw 3 adopts an integrated positive and negative thread screw structure, with a fixed seat 301 fixedly mounted at its midpoint. The fixed seat 301 is fixedly connected to the sliding mold support base plate 1, realizing the centered fixed installation of the bidirectional adjusting screw 3. At the same time, the bidirectional adjusting screw 3 is fixedly mounted between the two sets of channel-shaped forming mold frames 2 through the two side support frames 302, further enhancing the installation stability of the screw and preventing shaking and displacement during operation.

[0046] Two sets of symmetrically distributed adjustment frames 6 are slidably assembled between the two sets of channel-shaped forming mold frames 2. The two sets of adjustment frames 6 are respectively set to the positive and negative tooth sections of the bidirectional adjusting screw 3. The bidirectional adjusting screw 3 and the two sets of adjustment frames 6 are connected by two sets of symmetrical push mechanisms 4. The push mechanism 4 includes two adjusting nuts 401 symmetrically assembled on the positive and negative tooth sections of the bidirectional adjusting screw 3. Two push seats 402 are symmetrically fixed on each set of adjustment frames 6. Each adjusting nut 401 has a push connecting rod 403 hinged at both ends. The end of the push connecting rod 403 is hinged to the push seat 402 at the corresponding position, forming a symmetrical four-bar push structure.

[0047] Each set of adjustment frames 6 has an integrally formed sliding boss 601 at its bottom. The sliding boss 601 is embedded in the guide groove 101 and slides with it. The two sets of sliding bosses 601 pass through the guide groove 101 and are fixedly connected to the bottom of the left and right sides of the adjustable compartment 5 of the channel body, realizing bottom limiting guidance. At the same time, the inner side wall of the channel-shaped forming mold frame 2 is provided with a limiting groove 201, and the side wall of the adjustment frame 6 is correspondingly provided with a limiting slide 602. The limiting slide 602 is slidably assembled inside the limiting groove 201 to form a side limiting guidance structure. Through the bidirectional limiting cooperation between the bottom guide groove 101 and the side wall limiting groove 201, the adjustment frame 6 can drive the adjustable compartment 5 of the channel body to slide smoothly and linearly along a preset trajectory, completely eliminating the problems of deviation and jamming during the adjustment process.

[0048] The adjustable channel section 5 is a telescopic molding structure, consisting of a left U-shaped half-section 501 and a right U-shaped half-section 502 connected together. The left U-shaped half-section 501 is slidably inserted into the right U-shaped half-section 502, allowing for left and right telescopic expansion and contraction to achieve adaptive adjustment of the molding width. The left U-shaped half-section 501 consists of a left bottom plate 5011, a front upright plate 5012, a rear upright plate 5013, and a left arc-shaped sealing plate 5014, which is fixedly sealed at the ends of the left bottom plate 5011, the front upright plate 5012, and the rear upright plate 5013. The right U-shaped half-section 502 consists of a right bottom plate 5021, a front upright plate 5022, a rear upright plate 5023, and a right arc-shaped sealing plate 5024, which is fixedly sealed at the ends of the corresponding plates. The two arc-shaped sealing plates work together to form a complete channel end molding structure.

[0049] To improve the sealing performance and structural stability of the joints, the inner sides of the left compartment bottom plate 5011, the front upright plate 5012, and the rear upright plate 5013 are all provided with interconnected U-shaped assembly slots 5015, with a fixed insertion protrusion 5016 inside the U-shaped assembly slots 5015. Correspondingly, the inner sides of the right compartment bottom plate 5021, the front upright plate 5022, and the rear upright plate 5023 are all provided with insertion grooves 5025. The insertion protrusion 5016 and the insertion groove 5025 are vertically engaged and matched, resulting in a small joint gap and strong sealing performance, which can effectively prevent concrete leakage. At the same time, the outer surfaces of the left arc-shaped sealing plate 5014 and the right arc-shaped sealing plate 5024 are both welded and fixed with annular lifting rings 503, which facilitates the overall lifting, handling, disassembly, and maintenance of the equipment.

[0050] Before the formal paving construction, workers can precisely adjust the width of the equipment according to the design width and cross-sectional dimensions of the water supply channel in the construction drawings. The bidirectional adjusting screw 3 is rotated manually or by an external motor. Since the bidirectional adjusting screw 3 is an integrated positive and negative thread structure, when the bidirectional adjusting screw 3 rotates, the adjusting nuts 401 at both ends will move in a linear motion that is relatively close or far apart. When the two sets of adjusting nuts 401 move relative to each other, they will push the hinge transmission of the connecting rod 403 to pull the two sets of adjusting frames 6 to slide inward synchronously along the guide slide 101 and the limit slide 201, causing the left and right U-shaped half chambers to shrink and reduce the width of the channel. When the two sets of adjusting nuts 401 move away from each other, they will push the two sets of adjusting frames 6 to slide outward synchronously, causing the left and right U-shaped half chambers to stretch and increase the width of the channel. The entire adjustment process relies on a double-layer limiting structure for precise guidance throughout, with no deviation or jamming. The adjustment accuracy can meet the high-precision construction requirements of water conservancy projects and can be adapted to different specifications and working conditions such as small field irrigation canals, medium-sized water conveyance canals, and large municipal water supply canals.

[0051] After width adjustment and dimension verification, the equipment is hoisted into position, aligning the adjustable channel chamber 5 with the pouring location. It is then connected to the fully automatic feeding, vibration, and sliding control system, initiating fully automatic slipform paving. During construction, concrete is continuously poured into the forming cavity of the adjustable channel chamber 5. The entire equipment slides at a uniform speed along the length of the water supply channel. Through the shaping constraint of the adjustable channel chamber 5, continuous concrete pouring, compaction, and forming are integrated. This equipment eliminates the need for frequent manual adjustments and formwork removal, enabling fully automated continuous construction, significantly reducing manual intervention, and effectively solving the problems of cumbersome procedures and low efficiency in traditional formwork construction.

[0052] Meanwhile, during long-term, high-flow-rate concrete pouring, the vertically interlocking sealing structure maintains excellent sealing performance. When subjected to lateral concrete pressure, the interlocking protrusion 5016 and the interlocking groove 5025 become increasingly tighter, ensuring a stable and continuous seal. This completely prevents problems such as grout leakage and unevenness of the channel sidewalls caused by increased pressure. The double-layer, bidirectional limiting structure ensures the mold forming accuracy throughout the process, preventing mold displacement and excessive deviation in forming dimensions during equipment sliding. This significantly improves the straightness, flatness, and overall forming quality of the water supply channel. The formed channel structure is dense, has good impermeability, and a neat appearance, requiring no secondary repairs, effectively saving construction costs and shortening the construction period.

[0053] After the paving of a single section of the canal is completed, the equipment can be quickly transferred using the ring lifting ring 503 at the end to carry out the next construction process. After long-term use, the equipment can be directly disassembled by lifting the ring lifting ring 503, which facilitates the inspection, maintenance and replacement of the bidirectional adjusting screw 3 transmission structure, sliding guide structure and sealing structure. The equipment is highly convenient to maintain and has a longer service life, making it suitable for standardized construction scenarios of long-term and large-scale water conservancy projects.
