Description

Technical Field

[0001] This invention belongs to the technical field of slope protection paving equipment, specifically relating to a slope protection paving equipment for water conservancy projects. Background Technology

[0002] Slope protection is an engineering measure that involves laying, building, or planting protective layers on the surface of a slope to prevent it from being eroded or collapsing by water flow. Slope protection paving equipment is typically used on the upstream / downstream slopes of reservoir dams or river embankments to carry out continuous paving operations on steep slopes and long distances, thereby replacing manual masonry and small mechanical paving.

[0003] Current slope protection paving equipment basically includes a walking frame, material frame, vibrating unit, compaction unit, and automated control system. During operation, concrete is first introduced into the material frame, sinks into the inclined material frame by its own weight, and is evenly distributed to the entire range of the material frame under the action of the internal conveying auger. It is discharged from the bottom discharge port to spread the full width of the slope and avoid local accumulation or material shortage. Then, it is vibrated and compacted. The high-frequency vibration of the vibrating unit is controlled to liquefy the aggregate and make the air bubbles float to the surface and be discharged, ensuring the internal density of the concrete. At the same time, the walking frame moves slowly and uniformly along the guide rail, and finally forms a continuous slope.

[0004] However, traditional slope protection paving equipment still has the following drawbacks when in operation, especially for large-scale, long-distance regular slope protection projects: due to the overall length of the slope, the uniform distribution of concrete to the entire paving frame is slow, which slows down the vibration and compaction process and reduces the paving efficiency. At the same time, the use of flat pressure plates in combination with high-frequency vibrating motors to vibrate and compact the slope still results in uneven concrete distribution, and the vibration and compaction effect needs to be improved. Summary of the Invention

[0005] The purpose of this invention is to provide a slope protection laying device for water conservancy projects, so as to improve the efficiency of concrete distribution and vibration compaction, while accelerating the construction progress of large-scale, long-distance slope protection and ensuring the quality of slope protection.

[0006] To achieve the above objectives, embodiments of the present invention provide a slope protection paving device for hydraulic engineering, used for paving concrete on the slope surface, comprising: The slope protection walking frame is equipped with a material laying frame one and a material laying frame two. The material laying frame one and the material laying frame two are arranged at intervals along the length of the slope protection, and a support recess and a pre-pressing plate are provided between them. The support recess is located above the pre-pressing plate and is used to support the operating workers. The pre-pressing plate is used to pre-compact the concrete discharged from the material laying frame one. Several sets of vibrating rods, all of which penetrate the preload plate and are slidably connected to it, are arranged at intervals along the width of the slope protection, and can be inserted to vibrate the concrete after sliding. A compaction structure is provided on the side of the second material laying frame away from the first material laying frame, and is used to compact the concrete discharged from the second material laying frame onto the pre-compressed concrete of the pre-compressing plate.

[0007] In one possible implementation, each vibratory rod is fitted with an elastic element, the two ends of which act on the vibratory rod and the preload plate respectively to provide an upward restoring force to the vibratory rod.

[0008] One possible implementation also includes: The lower pressure plate is reciprocally slidably disposed at the bottom of the support recess. The bottom of the lower pressure plate has a lower pressure surface, which is located above the vibrator. After the lower pressure plate reciprocates, the lower pressure surface can repeatedly press down on each set of vibrators inserted into the concrete. A driving component is disposed on the preload plate and is used to drive the lower pressure plate to slide back and forth.

[0009] In one possible implementation, the tip of each vibrating rod has a spherical surface, and the lower pressure surface can intermittently press against the spherical surface after the lower pressure plate slides back and forth. The pressing surface can be any one of an isosceles trapezoid, a wavy shape, or a sawtooth shape.

[0010] In one possible implementation, a driving structure is further included, the driving structure being used to drive the lower pressure plate to slide reciprocally, the driving structure comprising: A screw is rotatably mounted at the bottom of the support recess. The lower pressure plate has a sliding part, which is threadedly connected to the screw. When the screw rotates, it can drive the lower pressure plate to slide back and forth. An electric motor is located at the bottom of the support recess and is used to drive the screw to rotate.

[0011] In one possible implementation, the drive structure further includes a displacement sensor and a controller. The displacement sensor is electrically connected to the controller. The displacement sensor is disposed on the preload plate and is used to detect the displacement of the lower plate and feed the signal back to the controller. The controller is used to receive the signal and control the forward and reverse rotation and speed of the motor. The controller is configured to execute the following control logic: The bottom of the supporting platform is divided into an upper section, a middle section and a lower section along the width of the slope protection; When the lower pressure plate is in the upper section, control the lower pressure plate to slide at a first speed; When the lower pressure plate is in the middle section, control the lower pressure plate to slide at a second speed; When the lower pressure plate is in the lower section, control the lower pressure plate to slide at a third speed; The first speed is greater than the second speed, and the second speed is greater than the third speed.

[0012] In one possible implementation, the supporting recess is U-shaped, and sliding grooves are provided on both sides of the bottom of the supporting recess. The screw is rotatably provided in each sliding groove, and the lower pressure plate has sliding parts on both sides. The two sliding parts are respectively slidably engaged in the two sliding grooves to make the lower pressure plate slide stably.

[0013] In one possible implementation, the compaction structure includes: A lifting frame is located on the side of the second material spreading frame away from the first material spreading frame; A compaction roller, with its two ends rotatably connected to the lifting frame, is used to compact the concrete discharged from the second paving frame onto the pre-compressed concrete of the pre-compressing plate. After the lifting frame is raised or lowered, it can drive the compaction roller to be raised or lowered, so as to adjust the gap thickness between the compaction roller and the slope protection.

[0014] In one possible implementation, the slope protection walking frame includes: An inclined support frame is used to install the first paving frame and the second paving frame. The bottom of the first paving frame and the bottom of the second paving frame are both provided with discharge ports. The upper and lower edges of the inclined support frame are provided with wheels so that the inclined support frame can drive the first paving frame and the second paving frame to move along the length of the slope protection.

[0015] In one possible implementation, both the top of the first material laying frame and the top of the second material laying frame are provided with a feeding port, and a guardrail is detachably provided at the feeding port to block impurities.

[0016] The significant technical effects of the embodiments of the present invention are as follows: For large-scale, long-distance slope protection projects, this paving equipment uses two paving frames, Frame 1 and Frame 2, arranged at intervals along the length of the slope to form a segmented continuous material supply. Frame 1 first discharges the first layer of concrete, which is quickly laid by a pre-compacting plate. Frame 2 then replenishes the concrete, with both sections supplying material simultaneously without waiting gaps, thus shortening the time it takes for the concrete to cover the slope and improving the paving rhythm. Furthermore, the paving equipment employs double compaction. The pre-compacting plate between the two paving frames pre-compacts the concrete discharged from Frame 1, and then the compaction structure performs the final compaction and shaping operation on the pre-compacted concrete and the concrete discharged from Frame 2. This segmented compaction further improves the slope shaping quality and is more suitable for large-scale, long-distance slope protection projects.

[0017] Meanwhile, by utilizing the space of the preload plate, a support recess can be added to support the workers. This does not occupy extra space. In large-scale, long-distance slope protection projects, it is convenient for workers to stand between the double material laying frames to manually intervene in the concrete, preventing concrete blockage. It also allows for real-time monitoring of the material placement, vibration, and compaction status, ensuring safety and not damaging the construction surface.

[0018] Furthermore, several sets of vibrating rods are arranged at intervals along the width of the slope to achieve uniform vibration of the slope. These vibrating rods are then installed at the preloading plate to combine preloading and vibration, taking into account both the density and surface smoothness of the concrete, while reducing the footprint.

[0019] In summary, the use of dual-laying frames for synchronous segmented material supply increases the concrete distribution speed, thereby improving the laying rhythm; and the use of pre-compression plates with independent vibrators enables more uniform and dense pre-compression vibration of the concrete. Finally, the compaction structure is used to finish the process, ensuring the overall quality of the concrete molding and making it suitable for large-scale, long-distance slope protection projects.

[0030] Definition: Slope protection 1 has a length direction of... Figure 1 The arrow direction is horizontal; the width direction of slope protection 1 is the extension direction from the top to the bottom of slope protection 1 and is perpendicular to the length direction of slope protection 1.

[0031] Please see Figure 1 , Figure 2This invention illustrates a slope protection paving device for hydraulic engineering, used to pave concrete on the surface of a slope 1. The device includes a slope protection walking frame 2, several sets of vibrating rods 7, and a compaction structure 10. Specifically, the slope protection walking frame 2 is an inclined support frame arranged to fit the inclination angle of the slope 1, i.e., an inclined support frame 201. Protective shells are installed at both the top and bottom of the inclined support frame 201. Walking wheels are installed inside the protective shells via rotating shafts. The walking wheels slide in cooperation with guide rails at the top / bottom of the slope 1, thereby enabling the slope protection walking frame 2 to... The system moves stably along the length of slope 1. The inclined support frame 201 is detachably equipped with parallel material spreading frames 3 and 4, which can be secured using bolts or other parts. Material spreading frames 3 and 4 are spaced apart along the length of slope 1. Material spreading frame 3 is used to first discharge concrete onto the surface of slope 1 to complete the first section of paving. Material spreading frame 4 is used to discharge concrete required for secondary material replenishment onto the surface of slope 1. Generally, both material spreading frames 3 and 4 have bottom discharge ports and contain built-in conveying augers (not shown). Figure 1 As shown, both section 3 of the material laying frame and section 4 of the material laying frame are trapezoidal with a larger top and a smaller bottom, so that the concrete can be concentrated and discharged from the discharge port under the action of the conveying auger.

[0032] Furthermore, both the top of the first material frame 3 and the top of the second material frame 4 can be provided with a feed inlet. A guardrail 12 for blocking impurities from entering the material frame can be detachably provided at the feed inlet. The guardrail 12 can be grid-shaped.

[0033] Between material laying frame 1 (3) and material laying frame 2 (4), there is a support recess 5 and a pre-compression plate 6 welded or integrally formed. The support recess 5, which is used to support the operators, is located above the pre-compression plate 6. It has a U-shaped structure, a flat bottom, and is surrounded on both sides. It does not occupy extra length space. It utilizes the unused area above the pre-compression plate 6 to provide a dedicated standing platform for operators, so that workers can stand between the two material laying frames to manually intervene in the concrete, prevent concrete blockage, and monitor the material laying, vibration, and compaction status in real time. It is safe and does not damage the construction surface.

[0034] The preload plate 6 located below the supporting recess 5 is used to closely adhere to the concrete paving surface and preload the concrete discharged from the paving frame 3. The preload plate 6 is generally flat. Furthermore, to optimize the vibration compaction effect, several sets of vibrating rods 7 are installed on the preload plate 6. Specifically, each vibrating rod 7 penetrates the preload plate 6 and slides with it. The upper end of the vibrating rod 7 extends above the preload plate 6, and the lower end is located inside the preload plate 6. After the vibrating rod 7 slides down, it can insert into the concrete to vibrate it, expel air bubbles, and improve the density. Several sets of vibrating rods 7 are arranged at intervals along the width of the slope 1, thus forming a vibration array covering the entire width of the slope 1. The spacing between them, whether equal or unequal, can be pre-adjusted based on the actual situation.

[0035] The compaction structure 10 is located on the side wall of the second material frame 4 away from the first material frame 3, and is used to compact the concrete after pre-compacting by the pre-compacting plate 6 and the concrete discharged from the second material frame 4.

[0036] Compared with existing technologies, this embodiment provides a slope protection paving device for water conservancy projects. For large-scale, long-distance regular slope protection projects, it adopts double paving frames arranged at intervals along the length direction to achieve segmented continuous material supply. Paving frame one 3 is first spread, and the pre-pressing plate 6 is quickly leveled. Paving frame two 4 is then replenished with material, and the synchronous material supply is achieved without waiting, which improves the paving efficiency. Furthermore, the pre-pressing plate 6 and the compaction structure 10 achieve double compaction. The segmented forming is more suitable for long-distance construction and improves the slope quality. At the same time, the space above the pre-pressing plate 6 is used to integrate the support recess 5, which does not occupy additional space. It allows workers to monitor and intervene in the material placement and vibration in real time between the two frames, preventing material blockage, making it safer, and without damaging the construction surface.

[0037] It is worth mentioning that this embodiment provides a slope protection paving device for water conservancy projects. The initial position of the vibrator 7 is that the upper end extends above the preload plate 6 and the lower end is inside the preload plate 6. This means that when the vibrator 7 is in its initial position, that is, before it slides down, the vibrator 7 will not remain in the position of being inserted into the concrete along with the preload plate 6, leaving marks on the concrete surface, and thus will not affect the preloading of the concrete. At the same time, during the reciprocating sliding process of the vibrator 7, due to its fast sliding speed, even if the paving rhythm of the paving device is increased, the moving speed of the inclined support frame 201 is much smaller than the reciprocating sliding speed of the vibrator 7 during actual operation. The vibrator 7 inserts into and extends out of the concrete in a short time, stably exerting the vibration effect, and will not leave marks on the concrete surface.

[0038] It is worth mentioning that this embodiment provides a slope protection laying device for water conservancy projects. The discharge ports of the double material laying frames are both a certain distance from the surface of the slope protection 1. The distance between the second material laying frame 4 and the surface of the slope protection 1 is slightly greater than the distance between the first material laying frame 3 and the surface of the slope protection 1. This avoids the second material laying frame 4 being unable or having difficulty discharging concrete from the discharge port. Even if the pre-pressing plate 6 is slightly lower than the two, this can ensure that the concrete is discharged smoothly, thereby ensuring the surface forming quality of the slope protection 1.

[0039] Please see Figures 3-5As a further embodiment, each vibrating rod 7 is fitted with an elastic element 8, with its two ends welded to the top of the vibrating rod 7 and the upper surface of the preload plate 6, respectively, to provide an upward restoring force to the vibrating rod 7. A lower pressure plate 9 is slidably connected to the bottom of the supporting recess 5 along the width direction of the slope protection 1. The bottom of the lower pressure plate 9 has a lower pressure surface 901, so that after the lower pressure plate 9 slides back and forth, the lower pressure surface 901 can repeatedly press down on each group of vibrating rods 7 to insert into the concrete. A driving component is provided on the preload plate 6 and is used to drive the lower pressure plate 9 to slide back and forth. This embodiment utilizes the elastic element 8 to enable the vibrating rod 7 to continuously vibrate back and forth, eliminating the need for a driving mechanism for each individual vibrating rod 7, resulting in a simpler and more compact structure.

[0040] In one specific implementation, the drive structure includes a screw 11 and a motor. The screw 11 is set along the width of the slope protection 1, and both ends are rotatably mounted on the bottom of the support recess 5 through bearing seats. The lower pressure plate 9 is welded or integrally formed to form a sliding part 902. The screw 11 passes through the sliding part 902 and is threadedly connected to the sliding part 902. Then, the motor drives the screw 11 to rotate, which can drive the lower pressure plate 9 to slide back and forth. The motor can be bolted to the bottom of the support recess 5 and located at one end of the screw 11, and its drive end is connected to one end of the screw 11.

[0041] As a further implementation of the drive structure, the drive structure also includes a displacement sensor and a controller. The displacement sensor is electrically connected to the controller. The displacement sensor is bolted to the preload plate 6 and is used to detect the displacement of the lower plate 9 in real time. A laser displacement sensor (non-contact, which is more suitable for the humid and dusty environment of the slope protection 1 construction site) can be used, and the signal is fed back to the controller. The controller can be integrated into the side wall of the equipment electrical control box / support platform 5 and is used to receive signals and control the forward and reverse rotation and speed of the motor.

[0042] The bottom of the supporting platform 5 is divided into three sections along the width of the slope protection 1: upper section, middle section, and lower section. The lower pressure plate 9 slides back and forth within these three sections. The specific control principle is as follows: the displacement sensor continuously collects the real-time position of the lower pressure plate 9, determines whether it is in the upper / middle / lower section, and sends the signal to the controller. The controller then outputs control signals according to preset logic: when the lower pressure plate 9 is in the upper section, it controls the lower pressure plate 9 to slide back and forth at a first speed; when the lower pressure plate 9 is in the middle section, it controls the lower pressure plate 9 to slide back and forth at a second speed; when the lower pressure plate 9 is in the lower section, it controls the lower pressure plate 9 to slide back and forth at a third speed; the first speed is greater than the second speed, and the second speed is greater than the third speed.

[0043] When the lower pressure plate 9 needs to switch between different sections, the above control logic is not executed. Instead, it depends on the worker's judgment of the actual situation. Simply put, if the lower pressure plate 9 vibrates back and forth in one section for a period of time, then at the section boundary, the motor is actively controlled by the worker through the electrical control box to prevent it from changing direction, so as to smoothly control the lower pressure plate 9 to enter the adjacent section.

[0044] In this embodiment, the vibration frequency is varied in a gradient along the width of the slope protection 1. The lower platen 9 slides back and forth at the upper section at the first speed to prevent concrete from flowing down the slope. The lower platen 9 slides back and forth at the middle section at the second speed to ensure the core compaction of the slope. The lower platen 9 slides back and forth at the lower section at the third speed to strengthen compaction by accumulating material flow in the lower part. This adapts to the differences in the self-weight distribution of concrete under large slopes and avoids over-vibration and flow in the upper part and insufficient compaction in the lower part.

[0045] As a specific implementation, each vibrating rod 7 has a spherical surface at its top. After the lower pressure plate 9 slides back and forth, the lower pressure surface 901 can repeatedly press against the spherical surface, thereby reducing frictional resistance, making the sliding of the lower pressure plate 9 easier, and reducing the motor load.

[0046] In one specific implementation, the pressing surface 901 can be either wavy or serrated. Figures 3-5 The example of an isosceles trapezoid is also given, which can more stably realize the reciprocating vibration of the vibrator 7. That is, during the reciprocating sliding of the lower pressure plate 9, each set of vibrator 7 is pressed down in sequence, continuously and repeatedly to achieve stable and orderly insertion and vibration.

[0047] As a specific implementation, each set of vibrating rods 7 includes several vibrating rods 7 arranged at intervals along the length of the slope 1, so that the several vibrating rods 7 are arranged in a matrix to ensure that the concrete is uniformly vibrated on the slope 1.

[0048] like Figure 6 As shown in the figure, in a specific embodiment, the bottom of the support platform 5 is provided with grooves 501 on both sides along the width direction of the slope protection 1. Each groove 501 is provided with a screw 11, and both sides of the lower pressure plate 9 are welded or integrally formed with sliding parts 902. The two sliding parts 902 are respectively slidably embedded in the two grooves 501. When the screw 11 rotates, the sliding parts 902 move back and forth along the grooves 501, driving the lower pressure plate 9 to slide back and forth stably along the width direction, avoiding deviation or jamming.

[0049] Please see Figure 7 As a specific implementation, the compaction structure 10 includes a lifting frame 1001 and a compaction roller 1002. The lifting frame 1001 adopts a structure such as a telescopic frame driven by a hydraulic cylinder and is bolted to the side wall of the second paving frame 4 away from the first paving frame 3. The two ends of the compaction roller 1002 are rotatably connected to the lifting frame 1001 through bearing seats. Thus, the compaction roller 1002 can move with the equipment and passively roll to roll and shape the concrete surface. After the lifting frame 1001 is raised and lowered, it can drive the compaction roller 1002 to be raised and lowered to adjust the gap thickness between the compaction roller 1002 and the slope protection 1 to adapt to different slope protection 1 design requirements.

[0050] As a specific implementation, the compaction roller 1002 may also have a built-in vibration motor to make the compaction roller 1002 vibrate and compact the concrete.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of protection of the claims of the present invention.
