Description

Technical Field

[0001] This invention belongs to the field of tamping hammer installation technology, and more specifically, relates to an auxiliary impact tamping hammer with tamping feedback function and its construction method. Background Technology

[0002] The most commonly used method for foundation compaction is dynamic compaction, which involves using a lifting device to drop a heavy hammer from a height, thereby using the hammer's own weight and impact force to compact the foundation soil, thereby improving the strength and stability of the foundation. The safety and lifespan of a building largely depend on the performance of the foundation, so the compaction of the foundation must be taken seriously.

[0003] Chinese utility model patent CN209339119 discloses a tamping hammer for dynamic compaction, including a main tamping hammer and an auxiliary tamping hammer located above the main tamping hammer. The main tamping hammer has multiple guide rods, and the auxiliary tamping hammer has multiple guide holes, which are slidably fitted onto the guide rods. The main tamping hammer has a main lifting ring with a main lifting cable, and the auxiliary tamping hammer has a sliding hole through which the main lifting ring passes. The auxiliary tamping hammer has an auxiliary lifting ring with an auxiliary lifting cable, and the auxiliary lifting cable and the main lifting cable are fixedly connected at the end away from the main tamping hammer. Through the above-mentioned configuration, this utility model allows for the simultaneous lifting of the main and auxiliary tamping hammers when the lifting cable is raised, achieving a stacked compaction effect by dropping the hammers in two stages. In the prior art, patent CN214271990U describes an easy-to-operate electric tamping machine with a handrail frame, improving the stability of the tamping machine and facilitating operation, thus solving the problem of high labor intensity for workers. However, it is inconvenient for construction in narrow areas and does not recover electrical energy.

[0004] The above-mentioned patented technical solutions still have the following shortcomings: (1) In environments with poor geological conditions, the hammer is easily attracted and cannot be lifted. This requires a lot of time and labor to lift the hammer manually, which greatly reduces the efficiency of the operation; (2) It is impossible to measure the distance. When the pit is too deep, it is not convenient to measure the amount of compaction, which increases the difficulty in the construction process. Summary of the Invention

[0005] To address the aforementioned deficiencies or improvement needs of existing technologies, this invention provides an auxiliary impact tamping hammer with compaction feedback function and its usage method. Secondary compaction is achieved by adding a slider-type auxiliary impact component to the main hammer body. Furthermore, an energy recovery component based on piezoelectric energy-generating plates is constructed, indirectly transferring energy to an inertial sensor and a wireless information feedback unit for power supply, thereby realizing energy recovery and utilization. The motion data of the entire hammer body during the compaction process is monitored by the inertial sensor and fed back via the wireless information feedback unit. The data reflects the settlement amount of the hammer body during each compaction, providing real-time guidance for subsequent compaction operations and improving the intelligence and data visualization of the compaction process.

[0006] To achieve the above objectives, according to a first aspect of the present invention, an auxiliary impact tamping hammer with a compaction feedback function includes: The hammer head unit, which is the main body of mass distribution, the auxiliary punching unit located on the hammer head unit, the compaction feedback unit installed above the auxiliary punching unit, and the suspension rope installed on the top surface of the compaction feedback unit. The auxiliary punching unit includes a central housing fixed above the hammer head unit and a slider-type auxiliary punching assembly vertically installed inside the central housing. The compaction feedback unit includes a top housing fixedly installed on the top of the auxiliary punching unit, an energy storage conversion component, an inertial sensor, and a wireless information feedback device disposed within the top housing; By releasing the suspension rope from a height, the hammer unit falls and impacts the foundation surface, compacting it. Subsequently, the slider-type auxiliary impact assembly, using inertia, impacts the hammer unit, achieving the auxiliary impact action. During the process, the speed of the hammer unit is measured by an inertial sensor and fed back via a wireless information feedback device.

[0007] Preferably, the hammer unit includes: Main hammer body, and hammer shell slidably sleeved on the surface of the main hammer body; The main hammer body includes a hammer end protrusion on its bottom surface and a hammer core groove opened in the center of the main hammer body. The hammer shell includes a vent hole aligned with the hammer end protrusion, a sliding connecting rod fixed at the center of the hammer shell and slidably connected to the hammer core groove, an anti-detachment groove formed in the sliding connecting rod, and an anti-detachment limiting pin fixed at the bottom of the hammer core groove and slidably connected to the anti-detachment groove.

[0008] Preferably, the main hammer body includes a pressure balance channel connecting the atmospheric space with the space between the main hammer body and the hammer shell.

[0009] Preferably, the slider-type auxiliary punch assembly includes: A central optical axis is vertically fixed at the center of the middle housing, an auxiliary punch mass block is slidably connected to the central optical axis, and a pull-back spring is disposed between the upper surface of the auxiliary punch mass block and the top surface of the inner cavity of the middle housing.

[0010] Preferably, the energy storage conversion component includes a rectifier circuit and a battery.

[0011] Preferably, the compaction feedback unit includes an energy recovery component for converting the kinetic energy of the slider-type auxiliary impact component into electrical energy.

[0012] Preferably, the energy recovery component includes: A piezoelectric energy-generating plate is provided on the side wall of the central housing shown, and a pawl is fixed to the side wall of the auxiliary punch mass block; there is horizontal overlap and interference between the pawl and the piezoelectric energy-generating plate; the piezoelectric energy-generating plate is a flexible plate.

[0013] Preferably, the piezoelectric energy-generating plates and the actuating plates are arranged in three vertical arrays on the side wall of the central housing and the side wall of the auxiliary punch mass block, respectively.

[0014] Preferably, it includes: a magnetic suction piece for detachably and tightly adsorbing the hammer shell onto the main hammer body.

[0015] According to a second aspect of the present invention, a method of using an auxiliary impact tamping hammer with a compaction feedback function includes the following steps: S100: With the help of hoisting machinery, the tamping hammer is suspended at the tamping point in the air. Then, the hoisting machinery is controlled to release the hoisting rope, and the tamping hammer will make free fall under the action of gravity. S200: During the descent, the auxiliary punch mass block remains stationary relative to the main hammer body; S300: Subsequently, the main hammer continues to fall. At the moment the main hammer impacts the foundation surface, it experiences a reaction force from the bottom surface, resulting in a reverse acceleration and a sudden decrease in velocity. Meanwhile, the auxiliary impact mass block on the central optical axis continues to fall due to inertia, creating a relative velocity between the auxiliary impact mass block and the main hammer. The auxiliary impact mass block slides down along the central optical axis and eventually impacts the hammer head unit, generating a secondary impact force on the hammer head unit and improving the compaction effect. Subsequently, under the action of the rebound force, the auxiliary impact mass block moves upward in the opposite direction, thus pulling the compaction hammer upward and reducing the difficulty of pulling the compaction hammer out of the foundation. S400: During the up-and-down movement of the auxiliary punch mass block along the central optical axis, the agitator on its side contacts and fluctuates with the piezoelectric energy-producing plate, causing the piezoelectric energy-producing plate to bend and deform. This generates an electric charge on the surface of the piezoelectric energy-producing plate due to the piezoelectric effect. This charge is transferred to the rectifier circuit via wires and finally stored in the battery, realizing energy recovery to power the inertial sensor and the wireless information feedback device. The motion data of the entire hammer compaction process is monitored by the inertial sensor and fed back through the wireless information feedback device. The data reflects the amount of settlement of the hammer each time it compacts, so as to guide the subsequent compaction operations in real time. S500: Subsequently, the hoisting rope is reconnected to the hoisting machinery hoisting rope and the lifting is controlled. Since the hammer shell and the main hammer body are kept in a detachable state under the action of the magnetic suction plate, the main hammer body is lifted first, while the hammer shell is embedded in the foundation soil. During the lifting of the main hammer body, under the action of the air pressure balance channel, the air pressure balance between the interlayer space between the main hammer body and the hammer shell and the external space is maintained. Furthermore, the air pressure is maintained between the bottom surface of the hammer shell and the contact surface of the foundation compaction pit through the ventilation hole, thereby solving the technical problem of construction difficulties caused by the low pressure in the compaction pit during the process of lifting the compaction hammer. S600: Finally, control the hoisting machinery to continue lifting the main hammer body. Under the sliding connection between the sliding connecting rod and the anti-detachment limit pin, the hammer shell is lifted and detached from the compaction pit, thus completing a single compaction.

[0016] In summary, compared with the prior art, the above-described technical solutions conceived by this invention can achieve the following beneficial effects: 1. The present invention discloses an auxiliary impact tamping hammer with a compaction feedback function. Secondary compaction is achieved by adding a slider-type auxiliary impact component to the main hammer body. Based on this, an energy recovery component based on a piezoelectric energy-generating plate is constructed, indirectly transferring energy to an inertial sensor and a wireless information feedback device for power supply, thereby realizing energy recovery and utilization. The motion data of the entire hammer body during the compaction process is monitored by the inertial sensor and fed back through the wireless information feedback device. The data reflects the settlement amount of the hammer body each time it is compacted, so as to guide the subsequent compaction operations in real time, improving the intelligence and data visualization of the compaction operation.

[0017] 2. The present invention provides an auxiliary impact tamping hammer with a compaction feedback function. A slider-type auxiliary impact assembly is formed by a central optical axis, an auxiliary impact mass block, and a return spring. This allows the auxiliary impact mass block and the main hammer to move relatively independently in the vertical direction. Thus, at the moment the hammer impacts the compaction point, the auxiliary impact mass block, due to inertia, impacts the main hammer downwards, achieving secondary compaction and effectively increasing the compaction volume per strike. Simultaneously, under the rebound force of the auxiliary impact mass block, it moves upwards, driving the tamping hammer upwards in the opposite direction, reducing the difficulty of subsequently pulling the tamping hammer out of the foundation.

[0018] 3. The present invention provides an auxiliary impact compaction hammer with a compaction feedback function. This is achieved by designing the hammer head unit as a detachable structure and providing an air pressure balance channel and ventilation holes on the side wall of the main hammer body. Under the action of the air pressure balance channel, the air pressure in the interlayer space between the main hammer body and the hammer shell is maintained in balance with the external space. Furthermore, the ventilation holes ensure that atmospheric air pressure is maintained between the bottom surface of the hammer shell and the contact surface of the foundation compaction pit, thereby solving the technical problem of construction difficulties caused by low pressure inside the compaction pit during the hammer-on process.

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Furthermore, the technical features involved in the various embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0024] like Figures 1-7 As shown in the embodiment of the present invention, the auxiliary impact tamping hammer with compaction feedback function includes: The main components of the mass distribution are: hammer head unit 1, auxiliary punching unit 2 located on top of the hammer head unit 1, compaction feedback unit 3 installed above the auxiliary punching unit 2, and suspension rope 4 installed on the top surface of the compaction feedback unit 3. The auxiliary punching unit 2 includes a central housing 210 fixed above the hammer head unit 1 and a slider-type auxiliary punching assembly 220 vertically installed inside the central housing 210. The compaction feedback unit 3 includes a top housing 300 fixedly installed on the top of the auxiliary punching unit 2, an energy storage conversion component 301, an inertial sensor 303 and a wireless information feedback device 302 disposed in the top housing 300. By releasing the suspension rope 4 from the high altitude, the hammer unit 1 falls and impacts the foundation surface and compacts it. Then, the slider-type auxiliary impact assembly 220 uses inertia to generate an impact action on the hammer unit 1, realizing the auxiliary impact action. During the process, the inertial sensor 303 measures the movement speed of the hammer unit 1 and provides feedback through the wireless information feedback device 302.

[0025] like Figure 3 As shown, in this embodiment of the invention, the hammerhead unit 1 includes: Main hammer body 110, hammer shell 120 slidably sleeved on the surface of the main hammer body 110; The main hammer body 110 includes a hammer end protrusion 112 on its bottom surface and a hammer core groove 113 opened in the center of the main hammer body 110. The hammer shell 120 includes a vent 121 aligned with the hammer end protrusion 112, a sliding connecting rod 122 fixed at the center of the hammer shell 120 and slidably connected to the hammer core groove 113, an anti-detachment groove 123 formed in the sliding connecting rod 122, and an anti-detachment limiting pin 114 fixed at the bottom of the hammer core groove 113 and slidably connected to the anti-detachment groove 123.

[0026] like Figure 3 As shown, in this embodiment of the invention, the main hammer body 110 includes a pressure balance channel 111 that connects the atmospheric space with the interlayer space between the main hammer body and the hammer shell 120.

[0027] In this embodiment of the invention, the hammer head unit 1 is designed as a detachable structure, and an air pressure balance channel 111 and a vent 121 are provided on the side wall of the main hammer body. Under the action of the air pressure balance channel 111, the air pressure balance between the interlayer space between the main hammer body 110 and the hammer shell 120 and the external space is maintained. Furthermore, the vent 121 maintains atmospheric air pressure between the bottom surface of the hammer shell 120 and the contact surface of the foundation compaction pit, thereby solving the technical problem of construction difficulties caused by low pressure inside the compaction pit during the hammer-handling process.

[0028] like Figure 3 In this embodiment of the invention, the slider-type auxiliary punch assembly 220 includes: A central optical axis 221 is vertically fixed at the center of the middle housing 210, an auxiliary punch mass block 222 is slidably connected to the central optical axis 221, and a pull-back spring 223 is disposed between the upper surface of the auxiliary punch mass block 222 and the top surface of the inner cavity of the middle housing 210.

[0029] In this embodiment of the invention, a slider-type auxiliary impact assembly 220 is formed by a central optical axis 221, an auxiliary impact mass block 222, and a pull-back spring 223. This allows the auxiliary impact mass block 222 and the main hammer body 110 to move relatively independently in the vertical direction. As a result, when the hammer body impacts the compaction point, the auxiliary impact mass block 222 impacts the main hammer body 110 downward due to inertia, thereby achieving secondary compaction and effectively increasing the compaction volume per impact. At the same time, the auxiliary impact mass block 222 moves upward under the action of the rebound force after impact, thereby driving the compaction hammer upward in the opposite direction and reducing the construction difficulty of pulling the subsequent compaction hammer out of the foundation.

[0030] like Figure 3 As shown, in this embodiment of the invention, the energy storage conversion component 301 includes a rectifier circuit and a battery.

[0031] like Figure 3 As shown, in this embodiment of the invention, the compaction feedback unit 3 includes an energy recovery component 310 for converting the kinetic energy of the slider auxiliary impact component 220 into electrical energy.

[0032] like Figure 3 As shown, in this embodiment of the invention, the energy recovery component 310 includes: A piezoelectric energy-generating plate 311 is provided on the side wall of the central housing 210 shown, and a toggle piece 312 is fixed on the side wall of the auxiliary punch mass block 222; there is horizontal overlap and interference between the toggle piece 312 and the piezoelectric energy-generating plate 311; the piezoelectric energy-generating plate 311 is a flexible plate.

[0033] like Figure 3 As shown, in this embodiment of the invention, the piezoelectric energy production plate 311 and the actuating plate 312 are each arranged in three vertical arrays on the side wall of the central housing 210 and the side wall of the auxiliary punch mass block 222.

[0034] like Figure 3 As shown in the embodiment of the present invention, the auxiliary impact tamping hammer with compaction feedback function includes: a magnetic suction piece 115 for detachably and tightly adsorbing the hammer shell 120 to the main hammer body 110.

[0035] like Figures 3-8 As shown in the embodiment of the present invention, the method of using the auxiliary impact tamping hammer with compaction feedback function includes the following steps: S100: With the help of hoisting machinery, the tamping hammer is suspended at the tamping point in the air. Then, the hoisting machinery is controlled to release the hoisting rope 4. Under the action of gravity, the tamping hammer makes free fall motion. S200: During the descent, the auxiliary impact mass block 222 remains stationary relative to the main hammer body 110. S300: Subsequently, the main hammer 110 continues to fall. At the moment the main hammer 110 impacts the foundation surface, it experiences a reaction force from the bottom surface, resulting in a reverse acceleration and a sudden decrease in velocity. Meanwhile, the auxiliary impact mass block 222 on the central optical axis 221 continues to fall due to inertia. This creates a relative velocity between the auxiliary impact mass block 222 and the main hammer 110. The auxiliary impact mass block 222 slides down along the central optical axis 221 and eventually impacts the hammer head unit 1, generating a secondary impact force on the hammer head unit 1 and improving the compaction effect. Subsequently, under the action of the rebound force, the auxiliary impact mass block 222 moves upward in the opposite direction, thereby pulling the compaction hammer upward and reducing the difficulty of pulling the compaction hammer out of the foundation. S400: During the up-and-down movement of the auxiliary impact mass block 222 along the central optical axis 221, the agitator 312 on its side contacts and fluctuates with the piezoelectric energy-producing plate 311, causing the piezoelectric energy-producing plate 311 to bend and deform. As a result, an electric charge is generated on the surface of the piezoelectric energy-producing plate 311 due to the piezoelectric effect. This charge is transferred to the rectifier circuit through the wire and finally stored in the battery to realize energy recovery and power the inertial sensor and the wireless information feedback device. The motion data of the entire hammer compaction process is monitored by the inertial sensor and fed back through the wireless information feedback device. The data reflects the amount of settlement of the hammer each time it compacts, so as to guide the subsequent compaction operations in real time. S500: Subsequently, the hoisting rope 4 is reconnected to the hoisting machinery hoisting rope and the lifting is controlled. Since the hammer shell 120 and the main hammer body 110 are kept in a detachable state under the action of the magnetic suction plate 115, the main hammer body 110 is lifted first, while the hammer shell 120 is embedded in the foundation soil. During the lifting process of the main hammer body 110, under the action of the air pressure balance channel 111, the air pressure balance between the interlayer space between the main hammer body 110 and the hammer shell 120 and the external space is maintained. Furthermore, the air pressure is maintained between the bottom surface of the hammer shell 120 and the contact surface of the foundation compaction pit through the ventilation hole 121, thereby solving the technical problem of construction difficulties caused by the low pressure inside the compaction pit during the process of lifting the hammer. S600: Finally, control the hoisting machinery to continue lifting the main hammer body 110. Under the sliding connection between the sliding connecting rod 122 and the anti-detachment limit pin 114, the hammer shell 120 is lifted and detached from the compaction pit, thus completing a single compaction.

[0036] In this embodiment of the invention, secondary compaction is achieved by adding a slider-type auxiliary impact component 220 on the main hammer body 110. On this basis, an energy recovery component 310 based on a piezoelectric energy-producing plate 311 is constructed, and the energy is indirectly transferred to the inertial sensor 301 and the wireless information feedback device 302 for power supply, thereby realizing energy recovery and utilization. The motion data of the entire hammer body compaction process is monitored by the inertial sensor and fed back through the wireless information feedback device. The data reflects the amount of settlement of the hammer body each time it is compacted, so as to guide the subsequent compaction operation in real time and improve the intelligence and data visualization of the compaction operation.

The above are merely preferred embodiments of this application.

As a result, an electric charge is generated on the surface of the piezoelectric energy production plate (311) due to the piezoelectric effect. This charge is transmitted to the rectifier circuit through the wire and finally stored in the battery to realize energy recovery and power the inertial sensor and the wireless information feedback device. The motion data of the entire hammer compaction process is monitored by the inertial sensor and fed back through the wireless information feedback device. The data reflects the compaction settlement of the hammer each time, so as to guide the subsequent compaction operations in real time. S500: Subsequently, the hoisting rope (4) is reconnected to the hoisting rope of the hoisting machinery and the lifting is controlled. Since the hammer shell (120) and the main hammer body (110) are kept in a detachable state under the action of the magnetic suction plate (115), the main hammer body (110) is lifted first, while the hammer shell (120) is embedded in the foundation soil. During the lifting process of the main hammer body (110), under the action of the air pressure balance channel (111), the air pressure balance between the interlayer space between the main hammer body (110) and the hammer shell (120) and the external space is maintained. Furthermore, the air pressure is maintained between the bottom surface of the hammer shell (120) and the contact surface of the foundation compaction pit through the ventilation hole (121), thereby solving the technical problem of construction difficulties caused by the low pressure inside the compaction pit during the process of lifting the hammer. S600: Finally, control the hoisting machinery to continue lifting the main hammer body (110). Under the sliding connection of the sliding connecting rod (122) and the anti-detachment limit pin (114), the hammer shell (120) is lifted and detached from the compaction pit, thus completing a single compaction.
