Description

Technical Field

[0001] This invention relates to the field of road construction equipment technology, and more specifically, to a guide beam installation device for cement-stabilized crushed stone base paving. Background Technology

[0002] In the paving of cement-stabilized crushed stone base courses, the installation accuracy and support stability of the guide beam directly determine the paving elevation accuracy and construction safety. Currently, the industry commonly uses the traditional string line method for guide beam positioning and elevation control. This method relies on continuous steel wire ropes and steel rods. The specific operation process is as follows: steel rods are inserted longitudinally every 10 meters at 30cm intervals on both sides of the paving section. One end of the steel wire rope is fixed to the rod, and the other end is tensioned using a tensioner to form a horizontal baseline. The paver then performs paving operations along the height of the steel wire rope. However, this traditional string line method has many unresolved core technical challenges in actual construction: Poor adaptability to complex terrain: The underlying layer (subgrade or base course) often has uneven compaction and water accumulation during the rainy season, resulting in potholes or local bulges. The steel rod can only be inserted vertically into the ground, and the height cannot be adjusted according to the flatness of the ground. This causes the wire rope baseline to be prone to tilting, resulting in a paving elevation deviation of more than ±3mm, far exceeding the ±2mm range allowed by the specifications. If the insertion depth of the steel rod is forcibly adjusted, it is easy to cause the steel rod to loosen, further aggravating the instability of the baseline. Weak support stability: The wire rope is only fixed by steel rods at both ends and supported by steel rods in the middle. The whole is in a "flexible tension" state. When facing the vibration of the paver operation, the wire rope is prone to high-frequency shaking, which causes the contact point between the steel rod and the ground to loosen, or even the steel rod to tilt and shift. Ultimately, this causes the guide beam to sink, which seriously affects the smoothness of the paving. Lack of elevation fine-tuning capability: Traditional stringing methods achieve elevation fine-tuning by adjusting the tension of the steel wire rope with a tensioner. However, the tension adjustment and elevation change are non-linear, resulting in poor fine-tuning accuracy. Furthermore, the height of multiple steel rods needs to be repeatedly checked during the adjustment process, and single-section adjustments are time-consuming, significantly increasing construction time. If a local elevation adjustment is required, the entire steel wire rope needs to be loosened, causing the baseline of other road sections to become inaccurate. Nighttime construction is less safe: Traditional stringing methods lack dedicated nighttime positioning components, relying solely on manual hand-held flashlights to illuminate the steel wire rope, resulting in insufficient visibility and the steel wire rope easily blending into the surrounding environment. Paver operators find it difficult to accurately identify the baseline position, leading to a higher accident rate of collisions with steel rods and deviations from the paving path at night compared to daytime. Some projects temporarily attach reflective strips to the steel rods, but these strips are exposed and easily damaged by impacts from gravel and contaminated by cement slurry, losing their reflective effect within a short period. Therefore, there is an urgent need for a guide beam installation device that can solve the pain points of traditional stringing methods, and has functions such as precise leveling, double stabilization, convenient fine adjustment, day and night coordinated positioning and protection, so as to improve construction quality and efficiency and reduce costs. Summary of the Invention The purpose of this invention is to provide a cement-stabilized crushed stone base paving guide beam installation device that is easy to use, allows for precise adjustment, and is suitable for nighttime construction.

[0013] The beneficial effects of this invention are as follows: This device, through modular collaborative design, achieves the following significant technical improvements compared to the traditional wire-hanging method (steel wire rope + steel rod): 1. Significantly improved adaptability to complex terrain: The leveling components adopt worm gear self-locking transmission + independent four-corner adjustment, which greatly improves the leveling accuracy. It can adapt to a certain degree of flatness deviation of the underlying layer, reduce the paving elevation deviation, meet the construction requirements of high-grade highways, and completely solve the pain point that traditional steel chisels cannot be used for leveling.

[0014] 2. Balancing stability with independent fine-tuning: The dual-embedded structure of "vertical fixed cone + oblique auxiliary cone" improves vibration resistance; The four-corner leveling structure, combined with the tray fine-tuning, further ensures the accuracy and consistency of the support height. Since the tray lifting height is fine-tuned, it drives a slight rotation. Due to the gear gap, it does not affect the state of the stabilizing components, achieving "precise fine-tuning + stable locking" guarantee. Traditional hanging lines cannot achieve this function. 3. Breakthrough in both efficiency and accuracy of elevation fine-tuning: The pallet adopts a fine-threaded rod for independent fine-tuning, which significantly shortens the adjustment time for a single section, and the local adjustment does not affect the baseline of other road sections, avoiding the problem of overall loosening of traditional wire ropes. 4. Balancing safety and economy in day and night construction: During daytime construction, the nighttime positioning components can be completely retracted for protection, reducing the wear rate of reflective markings, the failure rate of warning lights, extending service life, and reducing maintenance costs. The nighttime warning lights and reflective signs work together, making operation convenient and increasing visibility. 5. Significantly improved ease of operation: The device adopts a purely mechanical linkage design, which shortens the installation and commissioning time and improves construction efficiency.

[0028] In actual use: I. Construction Preparation and Equipment Placement Location determination: Based on the width of the base paving (e.g., 24m for urban main roads, 12m for mountain roads), mark the placement points of the device at 10m intervals along the longitudinal direction on both sides of the paving section, avoiding obvious sharp protrusions (such as stones, rebar ends) in the underlying layer (subgrade / base layer), and ensure that the soil compaction below the point is ≥90%; Device positioning: Place the trapezoidal cavity mounting base 1 stably on the marked point, so that the mounting groove 201 on the top of the mounting block 2 (the opening width is adapted to the square tube guide beam 3, and the gap is ≤2mm) faces the paving center line. Visually inspect the top surface of the mounting block 2 to ensure that there is no obvious tilt, thus initially ensuring the overall stability of the device. Mounting base 1 adopts a trapezoidal structure with a smaller upper part and a larger lower part. The lower base area is 30% larger than the upper base area, which can achieve anti-slip foundation through its own weight, avoiding the problem of easy tipping when traditional steel rods are initially placed. Mounting groove 201 pre-positions the guide beam direction, which shortens the subsequent guide beam alignment time. II. Precise Leveling of Complex Ground Leveling is performed in sections using a horizontal detection aid: First, adjust the two knobs 906 on the downslope side (or low-lying side) of mounting base 1 to drive the worm gear 905 inside mounting base 1 to rotate. The worm gear 905 meshes with the worm wheel 904 on the outside of the threaded cylinder 901, causing the threaded cylinder 901 and the inner threaded column 902 to rotate relative to each other, making the threaded column 902 extend and retract vertically. Then, adjust the two knobs 906 on the upslope side (or raised side) to gradually reduce the tilt angle. Accuracy verification: Repeatedly fine-tune the four knobs 906 until the electronic level shows that the tilt angle of the mounting base 1 is ≤0.3°. At this time, the support plate 903 at the bottom of the threaded column 902 is completely in contact with the ground, which is significantly larger than the grounding area of ​​the traditional steel rod, further improving the stability of the foundation. The leveling component uses a self-locking transmission of "worm 905 - worm wheel 904" to completely solve the problem that traditional steel rods can only be inserted vertically and cannot be leveled, which causes the wire rope to tilt. 3. Before installing the guide beam, flip the flipping plates in sequence (first fix the conical side, then assist the conical side). (1) First step: Flip the "fixed cone side flipping plate" to drive the fixed cone vertically into the soil. Flip-up plate identification: Confirm the function of the flip-up plates 5 on both sides of the mounting slot 201 - the one connected to the first stabilizing component 7 (fixed cone 703) is the "fixed cone side flip-up plate", and the one connected to the second stabilizing component 8 (auxiliary cone 805) is the "auxiliary cone side flip-up plate". Mark the function. Flipping operation: Hold the outer edge of the fixed cone-side flipping plate 5 with both hands and slowly flip it outward to a horizontal state until the slot 503 at the bottom of the flipping plate 5 is completely attached to the metal plate 404 on the outside of the support plate 4. The magnet inside the slot is attracted and fixed, and at the same time the extrusion strips 502 on both sides of the flipping plate are tightly attached to the inner wall of the mounting groove 201 to lock the flipping position. Power transmission and fixed cone insertion: When the flipping plate 5 flips, it drives the rotating rod 401 on the outside of the support plate 4 to rotate synchronously. The rotating rod coaxially drives the first rotating rod 601. The first gear 602 on the outside of the first rotating rod meshes with the second gear 603, and the second gear meshes with the third gear 604 to transmit power to the second rotating rod 606. When the second rotating rod 606 rotates, the outer first bevel gear 709 meshes with the second bevel gear 710 on the bidirectional lead screw 708, causing the bidirectional lead screw to rotate; the sliding sleeves 707 on both sides of the bidirectional lead screw move towards each other, pushing the cross connecting rod 706 to reduce the angle, and then pressing down on the pressing plate 701, causing the four fixed cylinders 702 to move down synchronously, and the fixed cones 703 at the bottom of the fixed cylinders are pressed vertically into the ground, forming a vertically rigid and stable structure. The fixed cone 703 is inserted into the soil first to establish the core vertical constraint of the device. The static friction force of the soil on the fixed cone is ≥5kN, which provides a stable foundation for the subsequent insertion of the auxiliary cone.

[0029] (2) Second step: Flip the “auxiliary cone side flipping plate” and drive the auxiliary cone to enter the soil at an angle. Flipping operation: After the fixed cone 703 is completely inserted into the soil, flip the auxiliary cone side flipping plate 5 to a horizontal state in the same way, and fix it to the metal plate 404 by magnetic attraction through the slot 503, and squeeze the rubber strip 502 to seal the inner wall of the installation groove 201; Power transmission and auxiliary cone soil entry: The auxiliary cone side flipping plate 5 drives the corresponding rotating rod 401, the first rotating rod 601 and the gear set (602 / 603 / 604) to transmit power to the second rotating rod 606 on the other side; The second rotating rod 606 drives the third bevel gears 810 on both sides to mesh with the fourth bevel gear 812 on the fourth rotating rod 811. The fifth bevel gear 813 on the lower side of the fourth rotating rod meshes with the sixth bevel gear 814 on the third rotating rod 807, causing the third rotating rod to rotate. The collar 808 on the third rotating rod drives the pressure plate 809 to rotate eccentrically. The pressure plate presses down on the spherical block 803 at the top of the sliding column 801 inside the fixed cylinder 702. The sliding column compression spring 802 moves down, pushing the four auxiliary rods 804 on the side wall of the sliding column to extend obliquely from the insertion hole 806 of the fixed cylinder. The auxiliary cones 805 at the bottom of the auxiliary rods are pressed obliquely into the ground, forming a "vertical + oblique" double stability with the fixed cone 703. The sequence of fixing the cone first and then the auxiliary cone avoids tilting caused by the lack of vertical restraint when the auxiliary cone enters the soil first. The angled entry design of the auxiliary cone 805 provides lateral anti-slip force, and together with the rebound locking of the spring 802, it improves the vibration resistance of the device and solves the vibration and swaying problem of traditional wire ropes. In addition, the flipping plate 5 increases the support area of ​​the guide beam, making it more stable. The flipping plate 5 is also convenient for storage and transportation when folded up.

[0030] IV. Placement and Precise Height Adjustment of Square Tube Guide Beam Guide beam placement: Two people work together to slowly place the square tube guide beam 3 into the installation groove 201, so that the bottom surface of the guide beam is completely in contact with the top surface of the support plate 4, and ensure that the length direction of the guide beam is consistent with the paving longitudinal direction (the end of the guide beam is aligned with the guide beam of the adjacent device). Height fine-tuning operation: Rotate the rotary knob 204 on the top of the mounting block 2. The rotary knob drives the vertical threaded rod 403 on the same axis. The threaded rod is threadedly engaged with the sliding block 402 in the center of the inner side of the support plate 4, which drives the sliding block to slide up and down along the guide groove 203 on the inner wall of the mounting groove 201, so as to realize the height adjustment of the support plate within a small range. Precision control and stability compensation: By rotating the scale markings on knob 204 and using a level to check the elevation of the top surface of the guide beam, fine-tuning is performed until the guide beam height deviation is ≤ ±0.5mm. During fine-tuning, the support plate 4 drives the rotating rod 401, the first rotating rod 601, and the first gear 602 to move vertically in sync, driving the second gear 603 and the third gear 604 to produce a small rotation of ≤0.3°. The gear meshing backlash (0.1-0.2mm) can compensate for the change in meshing depth caused by the lifting and lowering, and the stabilizing effect of the stabilizing components is basically unaffected. Levelness check: After fine-tuning, use an electronic level to check the levelness of the top surface of the guide beam to ensure that the deviation is ≤0.3°. The rectangular cross-section design of the guide groove 203 restricts the pallet 4 to move only vertically, preventing the guide beam from shifting during fine adjustments; the high-precision design of the fine-thread rod 403 enables fine adjustments at the ±0.5mm level, far exceeding the accuracy of ±2mm of the traditional hanging line, and does not require loosening the entire baseline, greatly shortening the adjustment time. V. Day and Night Positioning Component Mode Switching Daytime protection mode: The first rotating plate 1003 is flipped, causing the magnetic warning light 1001 to flip to the inside of the top groove 205. The counterweight 1006 maintains the horizontal stability of the first rotating plate. At the same time, the first rotating rod 1005 rotates. The first rotating rod, through the engagement of the seventh bevel gear 1007 with the eighth bevel gear 1008, drives the fifth rotating rod 1009 to rotate. The fourth gear 1010 on the outside of the fifth rotating rod engages with the fifth gear 1013 on the second rotating rod 1012, causing the second rotating plate 1011 to rotate inward by 180°, so that the reflective mark 1002 faces inward, thus preventing damage to the nighttime positioning components during daytime construction. Nighttime visibility mode: When working in the evening, manually press the first rotating plate 1003 again to flip it over, and the magnetic warning light 1001 will be located above the top groove 205; at the same time, the second rotating plate 1011 will be rotated outward by 180°, and the reflective mark will extend out of the side groove 206; the light and the reflective mark complement each other to ensure that the paver operator can clearly identify the paver within a certain range. The daytime storage design reduces the wear rate of reflective signs and the failure rate of warning lights, thus lowering maintenance costs; at night, the visibility distance is increased, which is better than traditional wired artificial lighting, and the collision accident rate is 0. VI. Paving Completion and Equipment Turnover Unlocking operation: After the paver completes the paving of this section along the guide beam, turn off the warning lights and switch to daytime protection mode; first flip the auxiliary cone-side flipping plate 5 upward (to overcome the magnetic attraction force), then flip the fixed cone-side flipping plate - the flipping plate flips in the opposite direction, driving the rotating rod 401, the first rotating rod 601 and the gear set to reverse the transmission, so that the second rotating rod 606 rotates in the opposite direction; Stabilizing component retraction: When the second rotating rod rotates in the reverse direction, the bidirectional lead screw 708 drives the sliding sleeve 707 to move in the reverse direction, the angle of the connecting rod 706 increases, and the lifting and pressing plate 701 retracts the fixed cone 703; at the same time, the third rotating rod 807 rotates in the reverse direction, the pressure plate 809 releases the top block 803, the spring 802 rebounds and pushes the sliding column 801 upward, and the auxiliary rod 804 retracts into the fixed cylinder 702; Disassembly and transfer: Two people work together to remove the square tube guide beam 3 from the installation slot 201, and manually carry the device to the section to be paved. Repeat the above steps until the base layer is paved. The sequence of retracting the auxiliary cone first and then the fixed cone can prevent the device from tipping over due to loss of lateral restraint. The stabilizing components are automatically retracted through mechanical linkage, eliminating the need for manual pulling of steel rods and retraction of steel wire ropes as required by traditional stringing. The lightweight design of the device improves turnover efficiency compared to traditional stringing, significantly enhancing overall construction efficiency.
