Description

Technical Field

[0001] This utility model belongs to the field of engineering machinery technology, specifically relating to a low-headroom 100-meter vibratory compaction equipment. Background Technology

[0002] Conventional vibratory compaction requires a truck crane or crawler crane for hoisting, with an electric or hydraulic vibratory compactor as the core equipment, supplemented by a water supply system. The construction process is complex and difficult to organize. Vibratory compaction relies on its own weight and horizontal vibration force for hole making. When encountering dense or cemented sand and gravel strata, hole making is difficult and inefficient, often requiring additional equipment, which increases costs. It places very high demands on the management of the work area, procedures, and equipment.

[0003] Meanwhile, traditional vibro-compaction construction is limited by vibro-compaction guide rods and hoisting equipment, making it difficult to complete 100-meter pile construction. In response, the low-headroom 100-meter vibro-compaction equipment and construction method developed in this patent can effectively break through the technical bottlenecks of traditional construction and provide a new solution for realizing 100-meter vibro-compaction pile construction. Utility Model Content

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a low-headroom 100-meter vibratory compaction equipment. This highly integrated equipment combines the functions of a crane, rotary drilling rig, pile driver, and excavator, and is equipped with a hydraulic power source and power supply system, a construction water tank, a mud treatment system, and a downpressurization system. This optimizes the construction process and improves overall efficiency in complex scenarios. Furthermore, the equipment's design emphasizes low headroom, making it particularly suitable for special construction environments with limited space, such as under bridges, in tunnels, canyons, windy offshore areas, and airport construction with height restrictions, solving the problem of limited space in traditional vibratory compaction construction. In addition, the equipment has the capability to construct to a depth of 100 meters. Through innovative vibratory compaction telescopic guide rod locking and downpressurization power systems, it overcomes the limitations of traditional vibratory compaction in terms of height, penetration ability, and construction complexity at depths of 100 meters, providing an efficient solution for future vibratory compaction methods in gravel layers and other complex deep pile foundation construction.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A low-headroom 100-meter vibratory impact equipment includes a tracked self-propelled chassis, a mast is hinged to the front end of the tracked self-propelled chassis, and an unfolding hydraulic cylinder is installed on the front end of the upper surface of the tracked self-propelled chassis, the unfolding hydraulic cylinder unfolds and retracts the mast;

[0007] A sliding block is slidably installed on the front side of the mast, and a vibratory impact machine lock telescopic guide rod is vertically installed on the surface of the sliding block. The vibratory impact machine lock telescopic guide rod is composed of multiple telescopic guide rods. A vibratory impactor is installed at the bottom of the vibratory impact machine lock telescopic guide rod, and a power head is provided at the bottom of the vibratory impactor. The power head is driven to rotate by a hydraulic system, which drives the guide rod and the vibratory impactor to work synchronously.

[0010] Furthermore, a support head is provided at the top of the mast, and a steel wire rope is connected to the top of the telescopic guide rod of the vibratory compactor lock. The steel wire rope is used to suspend the telescopic guide rod of the vibratory compactor lock.

[0011] Furthermore, the surface of the telescopic guide rod of the vibratory compactor is also connected to a combined pipe, and guide wheels are respectively installed on both sides inside the support head. The guide wheels are inclined and guide the combined pipe and the wire rope on both sides respectively.

[0012] Furthermore, the hoisting mechanism includes a base plate fixed to the rear of the tracked self-propelled chassis, support plates are provided on both sides of the top of the base plate, and a reel is rotatably installed on the outer side of the top of the support plate.

[0025] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0026] like Figures 1-4 As shown, a low-headroom 100-meter vibratory compaction equipment includes a tracked self-propelled chassis 1, which can adopt traditional machinery chassis such as cranes, rotary drilling rigs, pile drivers, and excavators to ensure stability during movement. A mast 2 is hinged to the front end of the tracked self-propelled chassis 1, and an unfolding hydraulic cylinder 11 is installed on the front end of the upper surface of the tracked self-propelled chassis 1. The unfolding hydraulic cylinder 11 unfolds and retracts the mast 2. During operation, the mast 2 is unfolded into a vertical state, and conversely, the mast 2 is laid flat to reduce its height.

[0027] A sliding block 23 is slidably mounted on the front side of the mast 2. A vibratory compactor telescopic guide rod 3 is vertically mounted on the surface of the sliding block 23. The vibratory compactor telescopic guide rod 3 consists of multiple telescopic guide rod sections, each equipped with a mechanical or hydraulic lock. This lock unlocks the second guide rod section after the drilling depth reaches the length of the first section, enabling deeper drilling and efficient operation within a limited vertical space. The length can be quickly adjusted according to construction needs, adapting to different pile foundation depths and effectively improving the construction efficiency and stability of the 100-meter vibratory compaction, ensuring smooth operation. A vibratory compactor 4 is installed at the bottom of the vibratory compactor telescopic guide rod 3. A power head 41 is located at the bottom of the vibratory compactor 4, driven by a hydraulic system to rotate, causing the guide rod and vibratory compactor 4 to operate synchronously, efficiently cutting the soil and rock. The vibratory compactor generates horizontal excitation force, adapting to different strata and squeezing the soil and rock to both sides to form holes, meeting the requirements of 100-meter deep pile foundation construction.

[0028] The tracked self-propelled chassis 1 is equipped with a winch mechanism 5 on its back, with a built-in anti-rotation mechanism to ensure stable up and down movement of the equipment when working at a depth of 100 meters. The winch mechanism 5 is used to store oil pipes, water pipes, air pipes, cables, material discharge pipes, and smart data cables.

[0029] like Figure 2 As shown, the tracked self-propelled chassis 1 is equipped with anti-tilt guards 12 on the sides of the tracks. Inclinometers 21 are installed on the surfaces of the mast 2 and the vibratory compactor telescopic guide rod 3. The inclinometers 21 monitor the verticality of the vibratory compactor 4 and transmit this data in real time to the control system of the anti-tilt guards 12. During construction, the verticality of the vibratory compactor 4 to the ground is precisely adjusted based on the monitoring data from the inclinometers 21 to ensure the quality of the pile foundation. Simultaneously, the low-headroom 100-meter vibratory compaction equipment can flexibly switch between the main unit's tooling and transportation states, improving construction efficiency.

[0030] like Figure 1 and Figure 2 As shown, a support head 22 is provided at the top of the mast 2, and a steel wire rope 7 is connected to the top of the vibratory compactor lock telescopic guide rod 3. The steel wire rope 7 is used to suspend the vibratory compactor lock telescopic guide rod 3 to provide power for the vibratory compactor lock telescopic guide rod to move up and down.

[0031] like Figure 1 and Figure 2 As shown, the surface of the telescopic guide rod 3 of the vibratory compactor is also connected to a combined pipe 6. Guide wheels 24 are installed on both sides inside the support head 22. The guide wheels 24 are inclined and guide the combined pipe 6 and the wire rope 7 on both sides respectively.

[0032] like Figures 2-4 As shown, the winch mechanism 5 includes a base plate 51 fixed to the rear of the tracked self-propelled chassis 1. Support plates 52 are provided on both sides of the top of the base plate 51. A reel 53 is rotatably installed on the outer side of the top of the support plate 52. The combined pipe 6 and the wire rope 7 are respectively wound inside the two reels 53 to prevent the pipes and wire rope 7 from getting tangled.

[0033] like Figures 2-4 As shown, the reel 53 is tilted, and the distance between the two reels 53 increases from front to back. The reels 53 are aligned with the guide wheels 24 on the same side to ensure smooth winding or lining.

[0034] like Figure 4 As shown, a constant pre-tension control system 54 is installed inside the support plate 52. The constant pre-tension control system 54 is used to control the rotation of the reel 53 to tighten the combined pipe 6 and the wire rope 7, ensuring the stability of the pipeline during the operation of the telescopic guide rod. When the telescopic guide rod is lowered, the tension is greater than the pre-tension force, causing the reel 53 to unwind and the pipeline to extend accordingly; when it is raised, the pre-tension force causes the pipeline to automatically rewind, enabling the 100-meter vibratory compaction construction to achieve multi-system integration and intelligence. Compared with traditional vibratory compaction construction, it greatly simplifies the process, improves efficiency and quality, reduces costs, and ensures construction safety.

[0035] like Figure 1 The combined pipe 6 is composed of oil pipes, water pipes, air pipes, cables, feeding pipes, and intelligent data cables, combining multiple pipes for easy deployment and retraction.

[0036] The working principle of this utility model is as follows: Before vibratory compaction, the construction site is equipped with water, electricity, and roads, and the site is leveled. Specifically, this includes setting up a water supply system, connecting a hydraulic power source and a power supply system, laying temporary roads to ensure the smooth entry of construction equipment, and using bulldozers or excavators to level the site, clear surface obstacles, and taking into account the drainage slope around the construction area. "Setting the pile position" involves using a total station or GPS measuring equipment to actually lay out the pile position coordinates to the site according to the design drawings, nailing the center of the pile position with small wooden stakes or steel bars, marking it with white lime, and finally checking with instruments to ensure the accuracy of the pile position.

[0037] After the pile positions are set, the machine is moved by the tracked self-propelled chassis 1, and the mast 2 is extended to a vertical position by deploying the hydraulic cylinder 11. The vibratory compactor 4 is started, the water and air pipes are opened, and the machine rotates to create a hole using its own weight and the lower pressurization system until the first section of the vibratory compactor's telescopic guide rod 3 reaches the set depth. The second section of the guide rod is then unlocked, and the machine continues to rotate to create the hole to that depth. Based on the designed pile depth, multiple telescopic guide rods are configured, and this process is repeated. After reaching the designed depth, the compaction stage begins. During this stage, stones are filled in, and the vibratory compactor is raised section by section for compaction. The telescopic guide rods are then retrieved, and the pile is finally completed. The entire process combines segmented hole creation and segmented compaction to ensure pile quality and construction safety.

[0038] During use, the wire rope 7 and the combined pipe 6 move with the guide rod. The guide wheel 24 is used to guide the wire rope 7 and the combined pipe 6 to prevent bending and / or knotting. The rotation of the reel 53 can wind or unwind them. The constant preload tension control system is used to ensure the stability of the wire rope 7 and the combined pipe 6.

[0039] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
