Description

Technical Field

[0001] This invention belongs to the field of water flow engineering, specifically a sidewall extrusion machine and its construction method. Background Technology

[0002] Water conservancy engineering, also known as hydraulic engineering, is an engineering system that controls and regulates surface water and groundwater to achieve goals such as flood control, irrigation, power generation, water supply, and soil and water conservation. Its core lies in utilizing hydraulic structures (such as dams, spillways, and canals) to regulate water flow and serve agricultural production, energy development, and ecological protection.

[0003] Sidewalls are vertical structures in hydraulic engineering used to constrain water flow and protect slopes, commonly found in spillways, chutes, and dams. As a crucial component of water flow engineering, the design, construction, and material selection of sidewalls directly impact the overall effectiveness of the project. A well-designed sidewall ensures smooth water flow, reduces scouring and erosion, and improves the stability and safety of the water flow engineering project.

[0004] Traditional construction techniques for sidewalls require multiple steps, such as formwork erection, formwork removal, and concrete vibration, which are cumbersome and rely on manual labor. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides an extrusion wall machine, which solves the problem that the traditional wall construction process in the prior art requires multiple procedures, such as formwork erection, formwork removal, and concrete vibration, which are cumbersome and reliant on manual operation.

[0006] An extrusion wall extrusion machine includes a frame, on which a forming chamber mechanism, a rear wheel mechanism, an auger chamber mechanism, a power chamber, a front wheel and steering system, and a quick-setting agent spraying device are provided;

[0007] The forming chamber mechanism is located at the end of the frame and is directly connected to the auger chamber mechanism, and is fixed to the frame by bolts;

[0008] The rear wheel mechanism is symmetrically and fixedly installed at the outer end of the frame;

[0009] The auger chamber mechanism is located between the power chamber and the molding chamber mechanism and is used to transport concrete mix to the molding chamber.

[0010] The power compartment is located in the middle of the frame and is connected to the auger compartment mechanism;

[0011] The steering system is used to control the steering of the front wheels;

[0012] The quick-setting agent spraying device and the end of the forming chamber are connected to each other to accelerate the initial setting of concrete.

[0013] Preferably, the molding chamber mechanism includes a molding chamber body, the bottom of which is fixed with a top template, an inner template and an outer template that are connected to each other, and a railing is also fixedly connected to the upper outer side of the molding chamber body.

[0014] Preferably, the rear wheel mechanism includes a lifting assembly and a sleeve assembly;

[0015] The lifting assembly includes a cylinder, with mounting plates fixedly connected to both sides of the cylinder, a connecting bracket fixedly connected to the output end of the cylinder, and a limit groove also provided on the outer side of the cylinder.

[0016] The sleeve assembly includes a sleeve body, a connecting rod, and a movable wheel. A slider is fixedly connected to the upper outer side of the sleeve body. A limit ring is fixedly connected to the upper end of the connecting rod. A spring is fixedly connected to the upper end of the limit ring. A shaft is fixedly connected to one side of the movable wheel.

[0017] The cylinder is fixedly installed on the frame after passing through the mounting plate with a screw. The slider is slidably embedded in the limiting groove. The connecting bracket and the sleeve body are fixedly connected by bolts. The limiting ring and the spring are both slidably embedded inside the sleeve body. The shaft is fixedly installed on the connecting rod by a bearing. The spring drives the limiting ring to move downward.

[0018] Preferably, the auger chamber mechanism includes an auger chamber, a feed inlet, an auger, a drive motor, a high-pressure oil pipe, a hydraulic pump, and a diesel engine. The feed inlet is located on the upper side of the auger chamber, the auger is rotatably installed inside the auger chamber, and the auger and the drive motor are fixedly connected by a coupling.

[0019] The diesel engine and the hydraulic pump are interconnected, and the mechanical energy of the diesel engine is converted into hydraulic energy. The hydraulic pump is connected to the drive motor through a high-pressure oil pipe to form a closed hydraulic circuit. The drive motor converts the hydraulic energy into mechanical torque and directly drives the auger to rotate.

[0020] The diesel engine and hydraulic pump are installed in the power compartment.

[0021] Preferably, the quick-setting agent spraying device includes an air pump, an oil-water separator, a pressure regulating valve, a storage tank, a spray pipe, an adjusting clamp, a pressure gauge, a suction head, a nozzle, and pipelines. The air pump serves as a power source and is driven by a diesel engine. The compressed air generated by the air pump is processed by the oil-water separator and the pressure regulating valve, and then transported to the storage tank through the pipelines.

[0022] One end of the nozzle extends into the interior of the storage tank and is connected to a suction head. The other end of the nozzle is located outside the storage tank and is connected to a nozzle. A drain switch is also installed on the nozzle.

[0023] The compressed air in the storage tank presses the liquid surface, causing the quick-setting agent to be delivered to the nozzle through the suction head and the discharge switch. The nozzle can adjust the spray angle by adjusting the clamp.

[0024] The pressure gauge is used to display the pressure inside the storage tank in real time. The pressure in the storage tank is adjusted by a pressure regulating valve to ensure that the quick-setting agent is sprayed evenly.

[0025] A method for constructing a sidewall extrusion machine includes the following steps:

[0026] Step 1: Preparations before construction:

[0027] a. Check the flatness of the pad surface to ensure that the flatness error within its width is less than ±4cm and the density is uniform;

[0028] b. Mark the driving route of the concrete mixer truck to avoid collisions with the sidewall extrusion machine;

[0029] c. Inspect the technical condition of the sidewall extrusion press, including the hydraulic oil level, diesel engine oil, accelerator spraying device, and wear condition of vulnerable parts;

[0030] Step 2: Equipment positioning and leveling:

[0031] a. Hoist the sidewall extrusion machine to the construction starting point and adjust the lower inner edge of the outer template of the forming chamber to coincide with the intersection line of the water-facing surface of the already formed extruded wall;

[0032] b. Adjust the horizontal level by using the lifting components of the rear wheel mechanism to make the distance between the bottom surface of the molding chamber and the pad surface 2-5mm;

[0033] c. Start the diesel engine and run it under no-load to check the hydraulic system pressure, auger rotation status, and air pressure stability of the quick-setting agent spraying device;

[0034] Step 3: Concrete delivery and sidewall forming:

[0035] a. The concrete mix is ​​received through the auger hopper mechanism, and the drive motor drives the auger to rotate through a closed hydraulic circuit, conveying the mix to the molding hopper mechanism;

[0036] b. The inner template, outer template and top template of the molding chamber work together to constrain the mixed material to form a trapezoidal cross-section extrusion wall. At the same time, the quick-setting agent spraying device sprays the quick-setting agent evenly onto the surface of the extrusion wall through air pressure control.

[0037] c. Monitor the molding speed in real time and control the auger speed by adjusting the diesel engine throttle to maintain the molding speed at 40-80 meters per hour;

[0038] Step 4: Dynamic Adjustment and Quality Control

[0039] a. The rear wheel mechanism uses springs to cushion ground impacts and adjusts ground clearance via cylinders to adapt to terrain undulations;

[0040] b. Control the front wheel steering through the steering system, and combine it with the detection of the base surface vertical line after the forming chamber to correct the straightness of the extrusion wall;

[0041] c. Adjust the pressure regulating valve according to the pressure value displayed on the pressure gauge to ensure uniform spraying of the accelerator;

[0042] Step 5: Post-construction procedures:

[0043] a. After stopping the material supply, clean the residual concrete in the auger chamber and molding chamber, empty the quick-setting agent storage tank and flush the pipeline with clean water;

[0044] b. Turn off the diesel engine, lift the sidewall extrusion press and perform maintenance, including lubricating key components and checking the welds and bolt tightness.

[0045] Preferably, in step three, the nozzle of the quick-setting agent spraying device dynamically adjusts the spray angle through the adjusting clamp to cover the forming surface of the extrusion wall with a slope ratio of 1:1.3-1:1.55 on the water-facing side.

[0046] Preferably, in step four, the lifting component of the rear wheel mechanism works in conjunction with the spring to drive the sleeve component to move vertically through the cylinder, thereby compensating for changes in equipment tilt angle caused by uneven ground in real time and keeping the horizontal error of the molding chamber less than ±3mm.

[0047] Preferably, the maintenance described in step five includes replacing the agitator head and baffle that have worn beyond the limit, and repairing the spiral blade circumference to a diameter of 268mm using D707 overlay welding, with a tolerance range of 0 to -2mm.

[0048] Preferably, the maximum particle size of the coarse aggregate in the concrete mix does not exceed 2 cm, the water-cement ratio is controlled at 1:1.31-1:1.45, and the amount of quick-setting agent added is 4%-6% of the cement dosage.

[0049] Compared with the prior art, the present invention has the following beneficial effects:

[0050] By integrating core modules such as the frame forming chamber, power chamber, and auger chamber, the continuous operation of concrete conveying, extrusion molding, and quick-setting agent spraying is realized, reducing process changeover time and greatly improving work efficiency. At the same time, the invention relies on the reaction force generated by the auger to drive the equipment to move. The travel speed can be controlled according to the feeding speed, so that the sidewall extruder moves along the travel direction. When the supply of the mixing material stops, the sidewall extruder stops traveling, the supply is restored, and the travel starts again.

[0051] The rear wheel lifting assembly (cylinder driven) works in conjunction with the spring buffer system to dynamically adjust the equipment's height off the ground and absorb ground impacts, maintaining the stability of the forming chamber operation.

[0052] The pneumatically driven accelerator spraying system achieves constant pressure spraying through oil-water separation, pressure regulating valve and pressure gauge, avoiding the clogging problem of traditional pumping and ensuring uniform atomization. Attached Figure Description

[0061] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0062] like Figure 1 As shown:

[0063] Example 1: The present invention provides an extrusion sidewall machine, including a frame, on which a forming chamber mechanism 1, a rear wheel mechanism 2, an auger chamber mechanism 3, a power chamber 4, a front wheel 5, a steering system 6, and a quick-setting agent spraying device 7 are arranged;

[0064] The forming chamber mechanism 1 is located at the end of the frame and is directly connected to the auger chamber mechanism 3, and is fixed to the frame by bolts;

[0065] The rear wheel mechanism 2 is symmetrically and fixedly installed at the outer end of the frame;

[0066] The auger chamber mechanism 3 is located between the power chamber 4 and the molding chamber mechanism 1, and is used to transport concrete mix to the molding chamber;

[0067] The power compartment 4 is located in the middle of the frame and is connected to the auger compartment mechanism 3;

[0068] Steering system 6 is used to control the steering of the front wheels 5;

[0069] The quick-setting agent spraying device 7 and the end of the forming chamber are connected to each other to accelerate the initial setting of concrete.

[0070] As can be seen from the above, the end of the frame of the present invention is provided with a forming chamber mechanism 1, which is fixed by bolts and directly connected to the auger chamber mechanism 3 to form a material conveying channel;

[0071] Rear wheel mechanisms 2 are symmetrically installed at both ends to provide driving stability;

[0072] The screw conveyor mechanism 3, as the transfer hub of concrete mix, is located between the power chamber 4 and the molding chamber. It uses screw conveyor technology to precisely push the concrete to the molding station.

[0073] The power compartment 4 is located in the middle section of the equipment and is connected to the auger compartment mechanism to provide driving force for the entire system;

[0074] The front wheels 5 are equipped with an independent steering system 6, which improves the equipment's maneuverability in complex working conditions through precise steering control;

[0075] The quick-setting agent spraying device 7 is connected to the end of the molding chamber and uses directional spraying technology to accelerate the initial setting process of concrete, significantly improving construction efficiency.

[0076] This equipment achieves a continuous operation process of concrete conveying, molding, and rapid setting through a modular layout. It is particularly suitable for large-scale continuous sidewall construction needs in fields such as water conservancy projects and road construction, and has the technical advantages of high automation and stable construction quality.

[0077] like Figure 2 As shown:

[0078] Example 2: The molding chamber mechanism 1 includes a molding chamber body 11. The bottom of the molding chamber body 11 is fixed with a top template 12, an inner template 13 and an outer template 14 that are connected to each other. A railing 15 is also fixedly connected to the upper outer side of the molding chamber body 11.

[0079] As can be seen from the above, this mechanism takes the molding chamber body 11 as the core, and its bottom integrates the top template 12, inner template 13 and outer template 14 through a rigid connection to form a precise concrete molding cavity;

[0080] Among them, the top template 12 is responsible for controlling the top shape of the side wall, the inner template 13 and the outer template 14 respectively constrain the inner and outer contours of the side wall, and the synergistic effect of the three ensures the geometric accuracy and surface flatness of the formed side wall.

[0081] A railing 15 is added to the upper outer side of the molding chamber body 11, which serves as a safety protection device for operators and provides auxiliary support points for equipment maintenance.

[0082] This invention achieves high stability of the template system through rigid connection, effectively resisting lateral pressure during concrete extrusion; the overall structure takes into account both construction accuracy and safety requirements, and is particularly suitable for engineering scenarios with stringent requirements for wall forming quality, such as high slopes and riverbank protection.

[0083] like Figures 3 to 5 As shown:

[0084] Example 3: The rear wheel mechanism 2 includes a lifting assembly 21 and a sleeve assembly 22;

[0085] The lifting assembly 21 includes a cylinder 211, with mounting plates 212 fixedly connected to both sides of the cylinder 211, a connecting bracket 213 fixedly connected to the output end of the cylinder 211, and a limit groove 214 also provided on the outer side of the cylinder 211.

[0086] The sleeve assembly 22 includes a sleeve body 221, a connecting rod 222 and a moving wheel 223. A slider 224 is fixedly connected to the upper outer side of the sleeve body 221. A limit ring 225 is fixedly connected to the upper end of the connecting rod 222. A spring 226 is fixedly connected to the upper end of the limit ring 225. A shaft 227 is fixedly connected to one side of the moving wheel 223.

[0087] The cylinder 211 is fixedly installed on the frame after passing through the mounting plate 212 via a screw. The slider 224 is slidably embedded in the limiting groove 214. The connecting bracket 213 and the sleeve body 221 are fixedly connected by bolts. The limiting ring 225 and the spring 226 are both slidably embedded inside the sleeve body 221. The shaft 227 is fixedly installed on the connecting rod 222 via a bearing. The spring 226 drives the limiting ring 225 to move downward.

[0088] As can be seen from the above, the lifting assembly 21 uses the cylinder 211 as the core driving unit, and is rigidly connected to the frame through the mounting plates 212 on both sides. The cylinder output end is fixedly connected to the connecting bracket 213. The outer side is provided with a limiting slide groove 214 to form a vertical guide rail. The sleeve assembly 22 slides with the slider 224 at the upper end of the sleeve body 221 and the limiting slide groove 214 to achieve precise limiting of the lifting movement.

[0089] The sleeve integrates a spring buffer system, which consists of a limiting ring 225 at the top of the connecting rod 222 and a spring 226 forming an elastic support structure. The spring preload drives the limiting ring to press down, thus providing dynamic load compensation for the moving wheel 223.

[0090] The moving wheel 223 moves forward through the bearing connection of the axle 227, while the vertical displacement is transmitted by the connecting rod 222;

[0091] The rear wheel height is actively adjusted by a cylinder drive, combined with the passive buffering mechanism of spring 226, which can not only adapt to the ground clearance requirements of different construction conditions, but also absorb the impact load caused by uneven ground.

[0092] like Figure 6 As shown:

[0093] Example 4: The auger chamber mechanism 3 includes an auger chamber 31, a feed inlet 32, an auger 33, a drive motor 34, a high-pressure oil pipe 35, a hydraulic pump 36, and a diesel engine 37. The feed inlet 32 ​​is located on the upper side of the auger chamber 31. The auger 33 is rotatably installed inside the auger chamber 31. The auger 33 and the drive motor 34 are fixedly connected by a coupling.

[0094] The diesel engine 37 and the hydraulic pump 36 are connected to each other, and the mechanical energy of the diesel engine 37 is converted into hydraulic energy. The hydraulic pump 36 is connected to the drive motor 34 through the high-pressure oil pipe 35 to form a closed hydraulic circuit. The drive motor 34 converts the hydraulic energy into mechanical torque and directly drives the auger 33 to rotate.

[0095] The diesel engine 37 and the hydraulic pump 36 are installed in the power compartment 4.

[0096] As can be seen from the above, the auger chamber mechanism 3 consists of an auger chamber 31, a feed inlet 32, and an auger 33, which constitute the main body of concrete conveying. The feed inlet 32 ​​is located at the top of the auger chamber, which facilitates the continuous feeding of external mixing materials.

[0097] Screw 33 is rigidly connected to drive motor 34 via a coupling, forming a spiral propulsion core;

[0098] The power system adopts a three-stage energy conversion architecture of diesel engine 37-hydraulic pump 36-drive motor 34: the diesel engine 37 outputs mechanical energy to drive the hydraulic pump 36 to generate high-pressure hydraulic oil, which is then transported to the drive motor 34 through the high-pressure oil pipe 35 and converted into mechanical torque, which finally drives the auger 33 to rotate at high speed to realize the directional extrusion and conveying of concrete.

[0099] The modular layout integrates the diesel engine 37 and the hydraulic pump 36 into the power compartment 4. The closed hydraulic circuit design significantly improves energy transfer efficiency while reducing the interference of mechanical vibration on the stability of the transmission.

[0100] Through the synergistic optimization of hydraulic and mechanical transmission, the construction requirements of high torque and low pulsation are achieved, making it particularly suitable for engineering scenarios requiring high-intensity continuous operation, such as water conservancy dams and roadbed slopes.

[0101] like Figure 7 As shown:

[0102] Example 5: The quick-setting agent spraying device 7 includes an air pump 71, an oil-water separator 72, a pressure regulating valve 73, a liquid storage tank 74, a spray pipe 75, an adjusting clamp 76, a pressure gauge 77, a suction head 78, a nozzle 79, and pipelines. The air pump 71 serves as a power source and is driven by a diesel engine 37. The compressed air generated by the air pump 71 is processed by the oil-water separator 72 and the pressure regulating valve 73 and then transported to the liquid storage tank 74 through the pipelines.

[0103] One end of the nozzle 75 extends into the interior of the storage tank 74 and is connected to the suction head 78. The other end of the nozzle 75 is located on the outside of the storage tank 74 and is connected to the nozzle 79. A drain switch is also installed on the nozzle 75.

[0104] Compressed air in the storage tank 74 presses the liquid surface, causing the quick-setting agent to be delivered to the nozzle 79 via the suction head 78 and the discharge switch. The nozzle 79 adjusts the spray angle via the adjusting clamp.

[0105] The pressure gauge 77 is used to display the pressure inside the liquid storage tank 74 in real time. The pressure in the liquid storage tank 74 is adjusted by the pressure regulating valve 73 to ensure that the quick-setting agent is sprayed evenly.

[0106] As can be seen from the above, the quick-setting agent spraying device 7 uses the air pump 71 driven by the diesel engine 37 as the core power source, and achieves precise atomization spraying of quick-setting agent through multi-stage purification and pressure regulation modules.

[0107] The compressed air generated by the air pump 71 flows through the oil-water separator 72 to remove impurities and moisture, and then is delivered to the top of the storage tank 74 after being stabilized by the pressure regulating valve 73, forming a closed pressure environment.

[0108] Compressed air in the storage tank 74 presses the liquid surface, forcing the quick-setting agent to enter the spray pipe 75 through the suction head 78 at the bottom. After the flow rate is controlled by the drain switch, it is sprayed directionally onto the concrete forming surface by the adjustable angle nozzle 79.

[0109] The injection system is equipped with a dual regulation mechanism: the pressure regulating valve 73 and the pressure gauge 77 work together to achieve constant pressure control in the liquid storage tank 74, ensuring a stable flow rate of the accelerator;

[0110] The nozzle 75 is equipped with an adjusting clip 76, which can dynamically adjust the spatial orientation of the nozzle 79 to adapt to the construction needs of sidewalls with different cross-sectional shapes.

[0111] The system integrates real-time pressure monitoring and multi-level pressure regulation functions, which can maintain the uniformity of spraying even under complex working conditions, effectively avoid local over-spraying or under-spraying of quick-setting agent, significantly improve the initial setting efficiency and molding quality of concrete, and is especially suitable for continuous construction operations in harsh environments such as high humidity and large temperature difference.

5. The construction method of the extrusion sidewall machine as described in claim 4, characterized in that, Includes the following steps: Step 1: Preparations before construction: a. Check the flatness of the pad surface to ensure that the flatness error within its width is less than ±4cm and the density is uniform; b. Mark the driving route of the concrete mixer truck to avoid collisions with the extrusion wall machine; c. Check the technical condition of the extrusion wall machine, including hydraulic oil level, diesel engine oil, quick-setting agent spraying device and wear condition of vulnerable parts; Step 2: Equipment positioning and leveling: a. Hoist the extrusion wall machine to the construction starting point and adjust the lower inner edge of the outer template of the forming chamber to coincide with the intersection line of the water-facing surface of the already formed extrusion wall; b. Adjust the horizontal level by using the lifting components of the rear wheel mechanism to make the distance between the bottom surface of the molding chamber and the pad surface 2-5mm; c. Start the diesel engine and run it under no-load to check the hydraulic system pressure, auger rotation status, and air pressure stability of the quick-setting agent spraying device; Step 3: Concrete delivery and sidewall forming: a. The concrete mix is ​​received through the auger hopper mechanism, and the drive motor drives the auger to rotate through a closed hydraulic circuit, conveying the mix to the molding hopper mechanism; b. The inner template, outer template and top template of the molding chamber work together to constrain the mixed material to form a trapezoidal cross-section extrusion wall.

Monitor the molding speed in real time and control the auger speed by adjusting the diesel engine throttle to maintain the molding speed at 40-80 meters per hour; Step 4: Dynamic Adjustment and Quality Control a. The rear wheel mechanism uses springs to cushion ground impacts and adjusts ground clearance via cylinders to adapt to terrain undulations; b. Control the front wheel steering through the steering system, and combine this with the detection of the vertical line of the base surface behind the forming chamber to correct the straightness of the extrusion wall; c. Adjust the pressure regulating valve according to the pressure value displayed on the pressure gauge to ensure uniform spraying of the accelerator; Step 5: Post-construction procedures: a. After stopping the material supply, clean the residual concrete in the auger chamber and molding chamber, empty the quick-setting agent storage tank and flush the pipeline with clean water; b. Turn off the diesel engine, lift the extrusion wall machine and perform maintenance, including lubricating key components and checking the welds and bolt tightness.
