Description

Technical Field

[0001] This utility model relates to the field of vibratory stone crushing pile technology, and in particular to a vibratory stone crushing pile machine vibratory device. Background Technology

[0002] Vibro-compaction stone pile technology, a common method for foundation treatment, utilizes the combined action of high-frequency vibration from a vibro-compaction device and high-pressure water flow to compact and replace the foundation soil, forming a composite foundation with crushed stone as aggregate. This effectively improves the bearing capacity of the foundation and reduces settlement, and is widely used in construction, road, and bridge engineering. In actual construction, the performance of the vibro-compaction device directly affects the construction quality and efficiency of the stone piles. Its core component, the vibro-compaction head, must simultaneously perform multiple functions, including soil breaking, aggregate filling guidance, and borehole compaction.

[0003] Existing vibratory compaction devices have some problems that need to be solved: On the one hand, the water outlet lacks an effective protective structure, and debris such as gravel and mud can easily enter the internal water channel during construction, causing pipe blockage, reducing the flushing effect of high-pressure water flow, and even damaging the vibration mechanism; on the other hand, the aggregate guiding structure of the vibratory compaction head can cause the filling material such as gravel to accumulate at the orifice, making it impossible to quickly and evenly fill the designated position in the orifice. Utility Model Content

[0004] This utility model proposes a vibratory compaction device for a vibratory compaction stone pile driver to solve the problem that existing vibratory compaction heads can easily have debris enter the water outlet, clogging the pipeline and damaging the vibration mechanism.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vibratory impactor for a stone crushing pile machine, comprising a vibratory impactor head and a connecting rod, wherein both the vibratory impactor head and the connecting rod are provided with water channels, and the bottom end of the vibratory impactor head is provided with a water outlet hole, the lower end of the vibratory impactor head is fixed with a pressure ring, the upper end surface of the pressure ring is a material feeding inclined surface, the lower end surface of the pressure ring is a pressing plane, and multiple through grooves are arranged in a ring array on the outer circumference of the pressure ring, and a stone-blocking component is provided inside the water outlet hole, the stone-blocking component including a baffle that can be deflected outward.

[0006] Preferably, the retaining element further includes a stop block, which is fixed inside the water outlet hole, and the baffle is hinged inside the water outlet hole. The stop block is used to prevent the baffle from deflecting upward from a horizontal position.

[0007] Preferably, a connecting pipe is connected to the top of the connecting rod and directly opposite the water channel, and a lifting ring is installed at the top of the connecting rod.

[0008] Preferably, the outer wall of the vibratory punch has a plurality of protruding teeth fixed in a ring array, the protruding teeth being located at the upper end of the pressure ring, and each protruding tooth corresponding to a through groove.

[0009] Preferably, the vibratory punch head has a protrusion fixed to its exterior, and the protrusion is located above the teeth.

[0010] Preferably, the protrusion includes a first frustum portion, a cylindrical portion, and a second frustum portion from top to bottom, with the first frustum portion and the second frustum portion arranged in opposite directions.

[0011] The technical effects and advantages provided by this utility model in the above technical solution are as follows: (1) By setting outward deflectable baffles and blocks in the water outlet, it can block debris such as gravel and mud from entering the water channel during the downward pressing of the vibratory head, avoid pipe blockage, ensure stable spraying of high-pressure water, and keep the water outlet unobstructed by the weight of the baffle when water is flowing, without affecting the flushing effect, thus improving the reliability and service life of the device.

[0012] (2) The protrusion adopts a three-section structure of the first truncated cone, the cylindrical part and the second truncated cone. This not only reduces the soil resistance when the vibratory punch sinks, but also strengthens the stirring effect on the soil and aggregate through the cone surface action. Combined with the high-frequency vibration of the vibratory punch and the high-pressure water flow scouring, it enhances the crushing ability of complex geology and expands the vibration density range.

[0013] (3) The inclined surface of the upper end of the pressure ring can guide the crushed stone to slide smoothly down the inclined surface. Combined with the through groove of the ring array, it can effectively avoid the accumulation of aggregate and improve the filling efficiency. The pressure plane of the lower end of the pressure ring can compact the aggregate in the hole during vibration. Combined with the crushing and stirring effect of the protruding teeth on the soil layer, it can further enhance the density of the pile body and ensure the bearing capacity of the composite foundation.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1-5 As shown, a vibratory compaction device for a vibratory stone crushing pile includes a vibratory compactor head 1 and a connecting rod 2, which are detachably rigidly connected and assembled using flange connection or threaded fastening. This facilitates later maintenance and replacement of vibratory compactors 1 with different specifications to adapt to different geological conditions (such as sand, silty clay, backfill soil, etc.). The vibratory compactor head 1 is integrally forged from high-strength alloy steel, possessing excellent wear resistance and impact resistance, and can withstand the severe friction and vibration loads with the foundation soil during construction. The vibratory compactor head 1 also integrates a high-frequency vibration mechanism (not shown in the figure), which is connected to an external vibration control system. During operation, it can drive the vibratory compactor head 1 to generate high-frequency vertical vibration, and the amplitude can be adjusted according to geological conditions and construction requirements. High-frequency vibration is transmitted to the surrounding soil layer through the vibratory head 1, causing the soil particles to rearrange and compact, thereby achieving the purpose of reinforcing the foundation. Both the vibratory head 1 and the connecting rod 2 are equipped with water channels 101. The top of the connecting rod 2, which is directly opposite the water channel 101, is connected to a connecting pipe 3. The bottom of the vibratory head 1 is equipped with a water outlet 8. The other end of the connecting pipe 3 is connected to an external high-pressure water supply system. During construction, high-pressure water flows through the connecting pipe 3 into the water channel 101 and sprays out from the water outlet 8 at the bottom of the vibratory head 1. The top of the connecting rod 2 is equipped with a lifting ring 4. The lifting ring 4 cooperates with the hook of the external lifting equipment to realize the vertical lifting and horizontal movement of the vibratory head, which facilitates the accurate positioning of the pile position during construction.

[0018] A pressure ring 7 is fixed to the lower end of the vibratory punch 1. Multiple protruding teeth 6 are fixed in a ring array on the outer wall of the vibratory punch 1. The protruding teeth 6 are located at the upper end of the pressure ring 7. The pressure ring 7 and the vibratory punch 1 are an integral structure. The upper surface of the pressure ring 7 is designed as a feeding slope, with the angle between this slope and the horizontal direction set at 30°-45°. This allows the crushed stone to slide down the slope into the hole during the stone filling process, preventing aggregate from accumulating above the pressure ring 7. The lower surface of the pressure ring 7 is a flat, pressure-resistant surface, allowing for the compaction of the aggregate filling the hole during construction. The compaction process improves the density of the crushed stone pile. In addition, multiple through grooves 71 are arranged in a ring array on the outer circumference of the pressure ring 7. The number of through grooves 71 is the same as the number of protruding teeth 6, and one protruding tooth 6 corresponds to one through groove 71. It can also serve as an auxiliary channel for aggregate to fall, further improving the aggregate filling efficiency. The protruding teeth 6 are made of wear-resistant alloy material and are fixed to the outer wall of the vibratory punch 1 by integral molding or welding. The protruding teeth 6 can enhance the crushing effect of the vibratory punch 1 on the surrounding soil layer and expand the compaction range.

[0019] The vibratory punch 1 has a protrusion 5 fixed on its exterior. The protrusion 5 is located above the protruding teeth 6. The protrusion 5 adopts a three-section design, including a first truncated cone 51 from top to bottom. The first truncated cone 51 and the second truncated cone 53 are arranged opposite to each other. The diameter of the first truncated cone 51 gradually increases from top to bottom. Its upper end face smoothly transitions with the outer wall of the vibratory punch 1, which can reduce the resistance of the soil layer to the protruding teeth 6 during construction and facilitate the sinking of the vibratory punch 1. The cylindrical part 52 has a uniform diameter structure and bears the main load of breaking the soil layer. The diameter of the second truncated cone 53 gradually decreases from top to bottom. This structural design can further agitate the soil layer and aggregate in the hole through the conical action of the second truncated cone 53 when the vibratory punch 1 vibrates, thereby improving the compaction effect.

[0020] In addition, see Figure 4 and Figure 5 As shown, the water outlet 8 is provided with a retaining stone 9 inside. The retaining stone 9 includes a baffle 91 that can be deflected outward. The retaining stone 9 also includes a stop block 92. The stop block 92 is fixed inside the water outlet 8. The baffle 91 is hinged inside the water outlet 8. The stop block 92 is used to prevent the baffle 91 from deflecting upward from the horizontal state.

[0021] As described above, when the connecting rod 2 is used to connect the lifting equipment, the baffle 91 can prevent debris such as gravel and mud from entering the water channel 101 through the water outlet 8 during the downward pressing of the vibratory punch 1. The limiting function of the stop block 92 restricts the deflection direction of the baffle 91, allowing it to open outward only, preventing the baffle 91 from folding upward and exposing the inside of the water outlet 8, thus ensuring that debris cannot enter the vibratory punch 1 from the water outlet 8.

[0022] Meanwhile, when water is discharged (at this time, the vibratory head 1 does not press down), the baffle 91 remains tilted downward under its own weight, so that the water outlet 8 is in the open state to achieve water intake.

[0023] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
