Description

Technical Field

[0001] This invention relates to the field of road construction technology, specifically to a road shoulder slipform machine and construction method. Background Technology

[0002] A road shoulder slipform machine is a specialized construction device used in highway and municipal road projects for the automatic paving and shaping of road shoulder concrete. Through slipform technology, it continuously and efficiently completes the cast-in-place construction of structures such as road shoulders, curbs, or drainage ditches without the need for formwork.

[0003] In recent years, some improved technologies have been proposed. For example, Chinese invention patent application CN114960369A (published on August 30, 2022) discloses a slipform device for sand-free large-pore concrete road shoulders. The device uses a slipform forming plate to form the concrete. By installing an extension plate, the sand-free large-pore concrete road shoulder is less prone to collapse during forming. After forming, the vertical and continuous facade line is achieved, resulting in a good facade line, high slope flatness, and a slope that meets construction requirements. The material is evenly distributed, and the strength meets construction requirements. This reduces the number of personnel required for construction, increases construction efficiency, and lowers construction costs. The mold hanging plate is fixed to the concrete slipform paver with connecting bolts. When the sand-free large-pore concrete is delivered to two-thirds of the hopper, the vibrator operates. The material baffle prevents the sand-free large-pore concrete from overflowing to the front, ensuring that all material is squeezed backwards after vibration, guaranteeing the compaction of the sand-free large-pore concrete and reducing waste during construction.

[0004] Although the aforementioned patent application CN114960369A provides a sand-free large-pore concrete shoulder slipform device, the existing shoulder slipform machine cannot adapt and adjust the shaping mechanism to different shoulder sizes required for construction, and cannot clean the shaping mechanism in a timely manner after the slipform shaping construction is completed, which affects the smoothness of the shoulder during subsequent slipform shaping construction.

[0005] Therefore, the aforementioned technical issues need to be resolved. Summary of the Invention

Furthermore, the present invention also provides a construction method for a road shoulder slipform machine, including the following steps: Step S1: Position the road shoulder slipform machine at the construction starting point via the walking mechanism, start the control panel and complete the system self-check, and at the same time inject concrete into the hopper, so that it is transported to the feeder through the guide seat, machine body and conveyor. Step S2: According to the design shoulder dimensions, the first dual-axis motor drive screw and connecting plate are activated one by one through the control mechanism to adjust the vertical height of the lifting platform and L-shaped shaping frame, and the telescopic cylinder is controlled to extend and retract to change the spacing of the shaping side plates, so as to achieve adaptive adjustment for different cross-sectional dimensions.

[0014] Compared with existing technologies, the advantages and effects of this application are as follows: 1. This invention, by setting an L-shaped shaping frame, telescopic cylinder and shaping side plate in the shaping mechanism, allows the spacing between the shaping side plate and the L-shaped shaping frame to be adjusted according to different road shoulder construction dimensions, thereby achieving adaptive shaping for road shoulder structures of various specifications. This solves the technical problems of existing road shoulder slide film machine shaping mechanisms being unable to be adjusted and having poor versatility, and improves the applicability and construction flexibility of the equipment.

[0015] 2. This invention integrates a flushing mechanism on the outside of the shaping mechanism, including a water pump, a hollow support shaft, a diverter frame, and multiple high-pressure nozzles. The hollow support shaft is driven by a geared motor to rotate the diverter frame, so that the high-pressure water flow can fully cover the forming area between the L-shaped shaping frame and the shaping side plate. This efficiently removes residual concrete after the slipform construction is completed, avoiding the problem of uneven road shoulder surface or linear deviation caused by material adhesion during subsequent construction, and ensuring the construction quality of continuous operation.

[0016] 3. The present invention sets up a composite lifting system in the control mechanism, which consists of a lifting platform, a lifting component and a lifting component. The lifting component uses a mechanical transmission structure of a dual-axis motor with screw-push seat-connecting plate to achieve stable vertical lifting. The lifting component provides auxiliary lifting force through the coordinated action of rope roller, rope and lifting ring. The combination of the two ensures that the shaping mechanism runs smoothly and is accurately positioned when adjusting the height.

[0017] 4. The construction method provided by this invention standardizes the entire process of road shoulder slipform construction through each step. On the one hand, this construction method can adjust the shaping size according to the actual project needs to ensure the geometric accuracy of the road shoulder. On the other hand, the shaping mechanism is cleaned immediately after each section of construction is completed to avoid the hardening of concrete affecting the construction quality of the next section, thereby improving the overall alignment consistency and surface flatness of the road shoulder and reducing manual intervention and rework rate.

[0037] The technical effects of this embodiment are as follows: By setting a lifting platform structure in the control mechanism with the coordinated action of the lifting and pulling components, this embodiment achieves precise and stable adjustment of the height of the shaping mechanism; the first dual-axis motor drives the symmetrical screw to drive the pusher seat and connecting plate, providing rigid support and vertical lifting capability; the second dual-axis motor synchronously controls the winding and unwinding of the ropes on both sides through bevel gear transmission, dynamically balancing and finely adjusting the posture of the lifting platform to ensure that the shaping mechanism remains horizontal and stable during the slip molding process.

[0038] Example 3 This embodiment describes a shaping mechanism 4 for a road shoulder slipform machine, further elaborated based on Embodiment 1 or 2 above. Please refer to... Figure 6 As shown, Figure 6 This is a schematic diagram of the outer structure of an L-shaped shaping frame for a road shoulder slip film machine; the shaping mechanism 4 includes an L-shaped shaping frame 32, which is a right-angled structure and is integrally formed by a vertical plate and a horizontal base plate or welded together; the L-shaped shaping frame 32 is located at the lower end of the mounting frame 15.

[0039] Specifically, as a preferred option, in order to achieve precise concrete placement, a feeder 31 is provided on one side of the lifting platform 17 and outside the mounting frame 15. A conveying pipe is connected between the feeder 31 and the conveyor 13 for receiving concrete. The bottom end of the feeder 31 is connected to the L-shaped shaping frame 32.

[0042] Example 4 This embodiment describes a rinsing mechanism 5 for a road shoulder slab membrane machine, further elaborated based on embodiments 1, 2, or 3 above. Please refer to... Figure 7 As shown, Figure 7 This is a schematic diagram of the structure at both ends of the side frame of a road shoulder sliding film machine; the rinsing mechanism 5 includes a side frame 37, which is located outside the L-shaped shaping frame 32 and connected to the L-shaped shaping frame 32.

[0043] Specifically, as a preferred embodiment, the side frame 37 is located on the side of the L-shaped shaping frame 32 away from the shaping side plate 35. The inner side of the side frame 37 is rotatably connected to a hollow support shaft 38. One end of the feeder 31 is equipped with a water pump 36. A water pump pipe is connected between the water pump 36's water inlet and the water tank 14, and a water pump pipe is connected between the water pump 36's water outlet and the hollow support shaft 38.

[0044] Specifically, as a preferred embodiment, a diversion frame 39 is provided at the end of the hollow support shaft 38 away from the drain pipe.

The drain pipe, hollow support shaft 38, diversion frame 39, and high-pressure nozzles 40 are interconnected. When the water pump 36 is started, the water flows sequentially through the pumping pipe, water pump 36, drain pipe, hollow support shaft 38, diversion frame 39, and high-pressure nozzles 40, forming a continuous, high-pressure cleaning water path.

[0045] Specifically, as a preferred option to further improve cleaning efficiency, a first spur gear 41 is fitted on the outer side of the hollow support shaft 38 near the diverter frame 39, and a reduction motor 42 is mounted on the upper end of the side frame 37. A second spur gear 43 is provided at the output end of the reduction motor 42, and the second spur gear 43 meshes with the first spur gear 41. When cleaning is required, the reduction motor 42 starts, driving the hollow support shaft 38 and the diverter frame 39 to rotate around the axis through the spur gear pair. This allows the high-pressure nozzle 40 to swing or rotate within a certain angle range, thereby dynamically adjusting the spray angle and achieving comprehensive rinsing of complex geometric surfaces.

[0046] The technical effects of this embodiment: This embodiment, by setting up a flushing mechanism consisting of a water pump, a hollow support shaft, a diverter frame and multiple high-pressure nozzles, and using a geared motor to drive gear transmission to achieve nozzle angle adjustment, can efficiently flush the working surface of the L-shaped shaping frame and the shaping side plate in all directions after construction, which can remove residual concrete and ensure the surface flatness of the subsequent road shoulder forming.

[0047] Example 5 This embodiment describes a construction method for a road shoulder slipform machine, which is further described based on the above embodiment 1, 2, 3, or 4. The method includes: Step S1: Position the road shoulder slipform machine at the construction starting point via the walking mechanism, start the control panel and complete the system self-check, and at the same time inject concrete into the hopper, so that it is transported to the feeder through the guide seat, machine body and conveyor.

[0048] Before actual construction, the operator first drives the machine slowly along the paved base or temporary access road to the starting position of the shoulder to be constructed, and ensures that the tires are on a flat foundation to avoid forming deviations due to settlement during construction.

[0049] Subsequently, the whole machine control system is started through the control panel built into one end of the chassis. The system performs a power-on self-test on the power supply module, each motor, telescopic cylinder, water pump and sensor, and enters standby mode after confirming that there are no faults.

[0050] Meanwhile, a concrete mixer truck unloads pre-mixed, sand-free, large-pore concrete into a hopper. The hopper is designed to hold approximately two-thirds of its volume to prevent overflow. Under gravity, the concrete flows sequentially through the guide seat and the internal channels of the machine body. Driven by the conveyor, it is uniformly and continuously transported to the feeder located above the shaping mechanism, providing a stable material supply for subsequent molding.

[0051] Step S2: Based on the designed shoulder dimensions, the first dual-axis motor drives the screw and connecting plate one by one through the control mechanism to adjust the vertical height of the lifting platform and L-shaped shaping frame, and controls the telescopic cylinder to extend and retract to change the spacing of the shaping side plates, so as to achieve adaptive adjustment for different cross-sectional dimensions.

[0052] After the operator inputs the target shoulder geometry parameters on the control panel, they calculate the required lifting height and side panel opening. First, the first dual-axis motor synchronously drives the screws on both sides to rotate, causing the symmetrically arranged guide seats to move along the screw axis. Then, through the connecting plate between the first and second shaft seats, the horizontal displacement is converted into the vertical movement of the lifting platform, thereby precisely adjusting the height of the L-shaped shaping frame from the ground to ensure that the formed bottom surface fits the base layer.

[0053] Secondly, two sets of hydraulic or electric telescopic cylinders operate synchronously, pushing the shaped side plate to slide laterally along the L-shaped frame, changing the distance between it and the inner wall of the L-shaped frame, thus adapting to shoulder sections of different thicknesses or with slopes. The entire adjustment process can be completed before construction or fine-tuned during travel to cope with changes in base elevation.

[0054] Step S3: Start the second dual-axis motor, which drives the rope winding roller to wind and unwind the rope through bevel gear transmission. In conjunction with the lifting ring and hook seat, the lifting platform is finely adjusted and stabilized to ensure that the shaping mechanism remains horizontal and rigid during construction.

[0055] After the initial positioning by the shaping mechanism, the second dual-axis motor starts, and the second bevel gear at its output end meshes with the first bevel gear at the end of the rope winding roller, driving the rope winding rollers on both sides to rotate synchronously, tightening or loosening the rope. The hook seat at the end of the rope engages with the lifting ring at the upper end of the lifting platform, forming a flexible but controllable lifting connection.

[0056] Step S4: During the forward movement of the equipment, concrete is evenly injected into the forming cavity enclosed by the L-shaped shaping frame and the shaping side plate through the discharge chute at the bottom of the feeder. Under the action of slip molding extrusion and self-weight, the concrete is continuously formed into a road shoulder structure with a vertical facade that meets the requirements of slope and strength.

[0057] While the traveling mechanism moves forward at a constant speed of 0.5–3 m / min, the feeder continuously delivers concrete into the forming cavity through the discharge chute at its bottom. This cavity is composed of the vertical surface and bottom surface of the L-shaped shaping frame, as well as adjustable shaping side plates, and its cross-sectional shape is completely consistent with the designed road shoulder.

[0058] After entering the cavity, the concrete is subjected to the combined action of the reaction force of the already formed road shoulder in front, the constraint force of the shaping frame, and its own weight, and is gradually compacted and slid upward and outward to take shape.

[0059] Step S5: After the single-section construction is completed, start the reduction motor to drive the hollow support shaft and the diverter frame to rotate to the washing position. At the same time, turn on the water pump to deliver the clean water in the water tank to multiple high-pressure nozzles through the water pump, the drain pipe, and the hollow support shaft to wash the residual concrete on the surface of the shaping frame and the shaping side plate in an all-round way.

[0060] After completing the construction of a section of road shoulder, a cleaning procedure is immediately initiated to prevent residual concrete from hardening and adhering, which could affect the quality of subsequent construction. First, the geared motor starts running, and the second flat gear at its output end drives the first flat gear on the outer circumference of the hollow support shaft, causing the entire distribution frame to rotate 90° to 180° around the axis of the hollow support shaft, turning the high-pressure nozzles that were originally facing the ground toward the working surface of the shaping mechanism.

[0061] Subsequently, the water pump draws water from the water tank at the top of the machine body, pressurizes it, and sends it through the drain pipe into the hollow support shaft. The water is then distributed through internal channels to multiple high-pressure nozzles on the distribution frame. These nozzles cover the inside of the L-shaped shaping frame, the working surface of the shaping side plate, and the outlet area of ​​the discharge chute, using a water pressure of 0.5–2 MPa to flush away the uncured concrete slurry. The flushing wastewater can either flow naturally or be collected by a temporary diversion channel to avoid contaminating the completed road shoulder surface.

[0062] Step S6: After rinsing, retract the shaping side plate, raise the shaping mechanism to a safe height, shut down the relevant actuators, drive the equipment away from the work area, complete the current construction cycle, and prepare for the next work section or maintenance.

[0063] After the rinsing process is completed, the telescopic cylinder retracts, restoring the shaping side plate to its minimum storage position. Then, the first dual-axis motor and the second dual-axis motor are activated again to lift the entire shaping mechanism to a safe height of 30-50 cm off the ground, avoiding collisions with obstacles or the already formed structure during the transfer process.

[0064] At this point, shut down the feeder, water pump, vibration device, and other actuators, leaving only the walking and basic lighting functions enabled. The operator drives the machine along the designated route out of the construction area and parks it at the designated parking point. If continuous operation is required, repeat the above steps to proceed to the next section; if the day's work is completed, thoroughly clean the hopper, conveying channel, and water tank, and check all connecting bolts, hydraulic lines, and electrical joints to ensure the equipment is in good standby condition, providing a guarantee for the next construction operation.

[0065] The technical effects of this embodiment are as follows: This embodiment achieves rapid adaptation to road shoulders of different sizes through an adjustable height and width shaping mechanism; in conjunction with a rotating high-pressure flushing system, residual concrete can be removed to avoid affecting the subsequent molding quality; the overall machine coordinated control is stable and efficient, improving construction accuracy and efficiency.

Various modifications and variations are possible with respect to the present invention. Any changes, modifications, substitutions, integrations, and parameter alterations to these embodiments within the spirit and principles of the present invention fall within the scope of protection of the claims of the present invention.
