Description

Technical Field

[0001] This utility model relates to the field of reservoir dam construction technology, and in particular to a compaction device for filling reservoir dams in plains. Background Technology

[0002] In the construction of dam filling for reservoirs in plains areas, compaction begins once the loose paving thickness and flatness meet the requirements. A 26t vibratory roller with raised blocks is used for compaction at a speed of 3 km / h. Compaction proceeds from both sides towards the center, using a staggered approach parallel to the longitudinal axis. Adjacent wheel tracks overlap by more than 0.1m, and the longitudinal overlap between adjacent sections is no less than 0.5m to ensure no missed areas or dead zones, guaranteeing uniform compaction.

[0003] However, in actual construction, the use of convex vibratory rollers requires hiring a professional engineering company. Workers cannot use the device themselves, and the engineering company for convex vibratory rollers needs to be booked and put in a queue. Therefore, this has a significant impact on the construction period. During some peak construction periods, the progress of the project may be delayed due to waiting for the installation of convex vibratory rollers. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a compaction device for filling dams in plain reservoirs, which addresses the shortcomings of the prior art. By setting a movable vibrating plate in front and combining it with a compaction cylinder with weight set in the rear, the device can achieve compaction for filling dams in plain reservoirs, thereby eliminating the dependence on the convex vibrating roller.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a compaction device for filling dams in plain reservoirs, including a vehicle body, a vibration mechanism disposed in front of the vehicle body, and a compaction mechanism disposed behind the vehicle body.

[0006] The vehicle body is equipped with a driver's cab, and the driver's cab is equipped with a control platform. The bottom of the vehicle body is equipped with wheels, and the control platform can control the movement and direction of the wheels.

[0007] The vibration mechanism has a downward-sloping support rod in front of it, and a pressure sensor is installed at the bottom of the support rod. The bottom of the support rod is inserted into the soil to be compacted.

[0008] The control platform is connected to the pressure sensor and the vibration mechanism respectively.

[0009] Furthermore, the vibration mechanism includes a fixed frame, with rollers at the bottom of the fixed frame, and the rear of the fixed frame connected to the vehicle body via a first connecting plate. A vibration plate is provided on the inner side of the fixed frame, and the edge of the vibration plate is connected to the inner side of the fixed frame via a spring. A support plate is provided above the vibration plate, and the support plate is connected to the vehicle body via a second connecting plate. A first hydraulic lifter is provided on the lower surface of the support plate, and the lifting end of the first hydraulic lifter is connected to the upper surface of the vibration plate.

[0010] The first hydraulic lift is signal-connected to the control platform.

[0011] Furthermore, the vibration plate is also equipped with a vibration enhancement mechanism, which is signal-connected to the control platform.

[0012] Furthermore, the vibration enhancement mechanism includes a telescopic cylinder disposed between the support plate and the vibrating plate. The length of the telescopic cylinder is adjustable. A second hydraulic lifter is disposed inside the telescopic cylinder. The fixed end of the second hydraulic lifter is fixed to the lower surface of the support plate. The lifting end of the second hydraulic lifter is provided with an electromagnet. The upper surface of the vibrating plate is made of magnetic metal material.

[0013] The control platform is connected to the second hydraulic lift and the electromagnet signal respectively.

[0014] Furthermore, the support rod is fixed to the front surface of the fixed frame.

[0015] Furthermore, the compaction mechanism includes a compaction cylinder, and a compaction shaft is respectively provided at both ends of the compaction cylinder along its axial direction. The compaction shaft is connected to the vehicle body through a connecting rod. The compaction shaft is movably connected to the connecting rod, and the vehicle body is fixedly connected to the connecting rod.

[0016] Furthermore, a counterweight is provided below the rolling mill shaft, and an opening is provided above the counterweight for the rolling mill shaft to pass through.

[0017] Furthermore, the inner wall of the opening is connected to the outer surface of the rolling shaft via a bearing.

[0018] Furthermore, a footrest is provided at the bottom of the vehicle body.

[0019] This utility model has the following advantages compared with the prior art:

[0020] This utility model provides a compaction device for dam construction in plain reservoirs. It integrates a self-controllable compaction system by combining a vibrating plate at the front, which can be independently raised and lowered and vibrates with real-time pressure feedback, with a compaction cylinder at the rear of the vehicle that uses counterweights to enhance compaction pressure. This design significantly overcomes the core pain point of traditional construction methods that rely on specialized companies to operate 26t vibratory rollers with raised blocks. Specifically, the front vibration mechanism (including a vibrating plate, support plate, first hydraulic lifter, and optional vibration enhancement mechanism) actively pre-compacts and initially levels the fill material. Pressure sensors at the bottom of its support rod monitor the resistance to soil penetration in real time, and the vibration frequency, amplitude, and downward pressure of the vibrating plate are intelligently adjusted via a control platform. The rear compaction mechanism utilizes the weight of the compaction cylinder and the additional weight provided by the counterweights to efficiently and continuously apply static or vibratory compaction (if the compaction cylinder itself has a vibration function) to the area pre-treated by vibration, ensuring the required compaction density and uniformity. This collaborative operation mode not only achieves a compaction effect comparable to that of a dedicated convex vibratory roller, but more importantly, it allows ordinary construction teams to complete all compaction processes simply by operating the integrated vehicle of this utility model (equipped with a cab, control platform, and wheels). This completely eliminates the dependence on professional engineering companies and their dedicated convex vibratory roller equipment, effectively avoids uncontrollable delays in the construction period caused by equipment reservations and queuing, and significantly improves construction efficiency and autonomy.

[0021] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0028] like Figure 1-4 As shown, the present invention provides a compaction device for filling dams in plain reservoirs, including a vehicle body 1, a vibration mechanism disposed in front of the vehicle body 1, and a compaction mechanism disposed behind the vehicle body 1.

[0029] The vehicle body 1 is provided with a driver's cab 2, and a control platform is provided inside the driver's cab 2. The bottom of the vehicle body 1 is provided with wheels 12, and the control platform can control the movement and direction of the wheels 12.

[0030] The vibration mechanism is provided with a downwardly inclined support rod 7 in front, and a pressure sensor 8 is provided at the bottom of the support rod 7. The bottom of the support rod 7 is inserted into the soil to be compacted.

[0031] The control platform is connected to the pressure sensor 8 and the vibration mechanism respectively.

[0032] In this utility model, the vehicle body 1, the vibration mechanism, and the rolling mechanism work together to solve the problem of construction delays caused by relying on professional bump vibratory rollers in the background art.

[0033] The vehicle body 1 can adopt the power and driving parts of a commonly used engineering vehicle, which refers to the platform operated by the worker to start the vehicle and make it move forward. It is also used to automatically control the vibration mechanism of this utility model.

[0034] The control platform is connected to the pressure sensor 8 and the vibration mechanism. The control platform acquires the pressure detected by the pressure sensor 8 under the soil and determines the compaction of the soil based on the pressure. This determines the vibration intensity of the vibration mechanism and controls the vibrating hook to complete the vibration, thus achieving the vibration effect before compaction. Combined with the subsequent compaction by the compaction mechanism, the compaction of the dam filling of the plain reservoir is realized. As a result, ordinary construction workers can drive the equipment and control the compaction process without professional skills.

[0035] The vehicle body 1 of this utility model adopts an engineering vehicle chassis structure, with wheels 12 at the bottom. The cab 2 integrates a control platform (such as a touchscreen or control panel). The control platform directly controls the direction and speed of the wheels 12 (achieving precise speed adjustment up to 3 km / h), and also integrates signal control functions for the vibration and compaction mechanisms. Foot pedals 11 are added to the bottom of the vehicle body 1, facilitating quick loading and unloading for operators and improving construction flexibility. The effect is that through integrated control, ordinary construction personnel can drive the equipment and control the compaction process without specialized skills, completely eliminating reliance on external professional companies.

[0036] The vibration mechanism and the compaction mechanism of this utility model will be described below.

[0037] The vibration mechanism includes a fixed frame 6, with rollers 9 at the bottom. The rear of the fixed frame 6 is connected to the vehicle body 1 via a first connecting plate 10. A vibration plate 18 is provided on the inner side of the fixed frame 6, and the edge of the vibration plate 18 is connected to the inner side of the fixed frame 6 via springs 17. A support plate 4 is provided above the vibration plate 18, and the support plate 4 is connected to the vehicle body 1 via a second connecting plate 3. A first hydraulic lifter 5 is provided on the lower surface of the support plate 4, and the lifting end of the first hydraulic lifter 5 is connected to the upper surface of the vibration plate 18. The first hydraulic lifter 5 is signal-connected to the control platform, and the control platform controls the first hydraulic lifter 5 to make the vibration plate 18 vibrate up and down, thus completing the impact of sudden vibration from below.

[0038] Among them, the bottom of the fixed frame 6 is equipped with rollers 9 to reduce the resistance of movement; the vibrating plate 18 is elastically connected to the inside of the fixed frame 6 by spring 17 to realize the vertical vibration degree of freedom; the support plate 4 is rigidly connected to the vehicle body 1 via the second connecting plate 3, and the lower surface of the support plate 4 is equipped with the first hydraulic lifter 5, the lifting end of which directly drives the vibrating plate 18 to move up and down; the support rod 7 is inclined and fixed to the front surface of the fixed frame 6, and the bottom is embedded with a soil pressure sensor 8 to detect the soil resistance in real time and feed it back to the control platform.

[0039] Based on data from pressure sensor 8, if the resistance exceeds a threshold, the control platform automatically adjusts the lifting frequency and amplitude of the first hydraulic lifter 5, causing the vibrating plate 18 to pre-compact the soil. During vibration, spring 17 buffers the vibration recoil force, maintaining equipment stability. Effect: Achieves intelligent pre-compaction and initial leveling of fill material, replacing the preliminary processing function of traditional bump vibratory rollers.

[0040] Furthermore, in order to enhance the vibration effect, the vibration plate 18 of this invention is also provided with a vibration enhancement mechanism 19, which is signal-connected to the control platform.

[0041] The vibration enhancement mechanism 19 includes a telescopic cylinder 19-1 disposed between the support plate 4 and the vibrating plate 18. The length of the telescopic cylinder 19-1 is adjustable. A second hydraulic lifter 19-2 is disposed inside the telescopic cylinder 19-1. The fixed end of the second hydraulic lifter 19-2 is fixed to the lower surface of the support plate 4. The lifting end of the second hydraulic lifter 19-2 is provided with an electromagnet 19-3. The upper surface of the vibrating plate 18 is made of magnetic metal. The control platform is connected to the second hydraulic lifter 19-2 and the electromagnet 19-3 respectively. When it is necessary to enhance the vibration, the control platform controls the electromagnet 19-3 to be energized to generate magnetic attraction to the vibrating plate 18. Subsequently, the second hydraulic lifter 19-2 and the first hydraulic lifter 5 work simultaneously to form a combined force vibration. Each time the vibration intensity is increased, one of the electromagnets 19-3 is energized to generate magnetic attraction to the vibrating plate 18.

[0042] The telescopic cylinder 19-1 has an adjustable length and is equipped with a second hydraulic lifter 19-2. The electromagnet 19-3 is fixed to the lifting end of the second hydraulic lifter 19-2 and magnetically engages with the vibrating plate 18, whose upper surface is made of magnetic metal.

[0043] The control platform energizes the electromagnet 19-3 to generate magnetic attraction to the vibrating plate 18. Subsequently, the second hydraulic lift 19-2 and the first hydraulic lift 5 work simultaneously to form a combined force vibration. Effect: Through the combined force vibration, the compaction efficiency of high-density fill material is significantly improved, which is especially suitable for the deep compaction requirements of reservoir dams.

[0044] In addition, in this utility model, the support rod 7 is fixed to the front surface of the fixed frame 6.

[0045] The compaction mechanism includes a compaction cylinder 15, and a compaction shaft 14 is respectively provided at both ends of the compaction cylinder 15 along its axial direction. The compaction shaft 14 is connected to the vehicle body 1 through a connecting rod 16. The compaction shaft 14 is movably connected to the connecting rod 16, and the vehicle body 1 is fixedly connected to the connecting rod 16.

[0046] A counterweight 13 is provided below the rolling mill 14, and an opening is provided above the counterweight 13 for the rolling mill 14 to pass through. Furthermore, the inner wall of the opening is connected to the outer surface of the rolling mill 14 via a bearing.

[0047] The roller 15 is equipped with roller shafts 14 at both ends, which are movably connected to the connecting rods 16 via bearings; the counterweight 13 is sleeved on the roller shaft 14, and the inner wall of the opening is connected via bearings, which can be disassembled and replaced to adapt to different compaction requirements.

[0048] After the vibration mechanism completes pre-compaction, the compaction cylinder 15 rolls under vehicle traction. Its own weight is approximately 26 tons, and the additional pressure from the counterweight 13 (e.g., 5-10 tons) further compacts the pre-compacted area. The bearing design of the compaction shaft 14 ensures free rotation of the compaction cylinder, preventing soil adhesion. Results: Step-by-step compaction by the front and rear mechanisms, combining vibration and static pressure / vibration compaction, achieves the same compaction uniformity as a traditional bump vibratory roller, with wheel track overlap >0.1m and overlap ≥0.5m.

[0049] In this utility model, a foot pedal 11 is provided at the bottom of the vehicle body 1, which makes it easy for the driver to board the vehicle and perform driving operations.

[0050] In summary, this invention offers several advantages. First, in terms of movement control, operators can set the movement path (longitudinal parallel to the central axis, staggered forward and backward method) via a control platform. Second, in terms of intelligent compaction, the pressure sensor 8 on the support rod 7 optimizes vibration parameters in real time, leading to compaction by the counterweight of the roller. Third, in terms of continuous construction, a single unit completes both vibration and compaction in one operation, eliminating the need to change equipment mid-construction. This allows ordinary construction teams to operate independently, resolving delays caused by waiting in line with professional companies. The vibration-compacting synergistic design improves compaction efficiency by over 40%, ensuring no missed compaction or dead zones. The adjustable design of the counterweight 13 adapts to different soil types, offering superior versatility compared to fixed-parameter vibratory rollers with raised blocks.

[0051] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model. Any simple modifications, alterations, or equivalent structural changes made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
