Description

Technical Field

[0001] This utility model relates to the field of road engineering technology, specifically to a shallow drilling and hammer splitting integrated device. Background Technology

[0002] In road construction projects such as road reconstruction and expansion, bridge maintenance, tunnel demolition, and underground foundation treatment, it is often necessary to demolish shallow concrete or rock structures at specific points. To accomplish this, existing technologies typically employ a split-type construction method. This involves first using drilling equipment to create holes in the concrete or rock surface, then manually inserting a splitting rod into the holes, and finally applying pressure or impact force to the splitting rod inside the holes using a splitting device to achieve the splitting and fracturing of the structure.

[0003] While this method of operation is widely used, it has significant drawbacks. First, drilling and splitting require two separate sets of equipment, necessitating repeated changes in tools and positions, resulting in a cumbersome and inefficient process. Second, the splitting rod must be manually inserted into the hole, increasing labor intensity and posing safety hazards due to the high pressure. Third, drilling positioning relies heavily on the experience and judgment of construction workers, lacking real-time detection methods, making it difficult to accurately avoid internal reinforcing steel or critical structures, and posing risks of drilling deviation or accidental injury. Furthermore, the lack of unified coordination and control between the various pieces of equipment during the operation prevents mechanization, and the construction accuracy, efficiency, and safety fail to meet the demands of modern engineering. Utility Model Content

[0004] To address the problems mentioned in the background section, a shallow drilling and hammering fracturing integrated device is proposed. The technical solution adopted by this utility model is as follows:

[0005] A shallow drilling and hammer splitting integrated device includes a housing serving as an installation platform for supporting components. Inside the housing, near the forward direction end, is a detection mechanism for detecting the distribution of reinforcing bars within a target location. Behind the detection mechanism is a drilling mechanism for performing fixed-depth drilling operations. Behind the drilling mechanism is a hammer splitting mechanism for splitting shallow concrete. Inside the housing, away from the detection mechanism, is a splitting nail receiving and dispatching mechanism for storing and transporting splitting nail bodies. The end gripper of the splitting nail receiving and dispatching mechanism is located between the drilling mechanism and the hammer splitting mechanism.

[0006] Furthermore, the detection mechanism includes a rebar scanner and a lifting probe. The rebar scanner is located at the bottom of the housing near the forward direction end, and the lifting probe, which penetrates the housing, is located at the bottom of the rebar scanner.

[0007] Furthermore, the drilling mechanism includes a first hydraulic cylinder and a drilling component. The top of the first hydraulic cylinder is fixedly mounted on the housing, and the drilling component is provided at the bottom of the first hydraulic cylinder. A drill bit is movably mounted at the bottom of the drilling component, and the drill bit penetrates the bottom of the housing.

[0008] Furthermore, the heavy hammer splitting mechanism includes a second hydraulic cylinder and a hammer pressing component. The top of the second hydraulic cylinder is fixedly installed on the housing, and the hammer pressing component is provided at the bottom of the second hydraulic cylinder. A hammer head is movably installed at the bottom of the hammer pressing component, and the hammer head penetrates through the bottom of the housing.

[0009] Furthermore, the splitting nail receiving and dispatching mechanism includes a splitting nail magazine, a material conveying guide rail, and an end gripper. The splitting nail magazine is fixedly disposed at the bottom of the housing away from the detection mechanism. One side of the splitting nail magazine is fixedly connected to one end of the material conveying guide rail, and the other end of the material conveying guide rail is fixedly connected to the end gripper. A lifting guide rail is disposed next to the end gripper, and the end gripper is slidably mounted on the lifting guide rail.

[0010] Furthermore, the splitting nail body includes a splitting nail head, a connecting block, and willow-leaf steel strips. Several willow-leaf steel strips are hinged to the outside of the connecting block, and the willow-leaf steel strips are narrower at the top and wider at the bottom. The splitting nail head is slidably installed on the connecting block, and the end of the splitting nail head abuts against the inner side of several willow-leaf steel strips.

[0011] Furthermore, the housing also includes a numerical control system and a hydraulic control system. The numerical control system is responsible for executing logical instructions, and the hydraulic control system is used to provide power to each working component.

[0012] Furthermore, the end gripper, which is slidably mounted on the lifting guide rail, is positioned at the midpoint between the drilling mechanism and the hammer splitting mechanism.

[0013] Furthermore, the bottom of the outer shell is provided with several omnidirectional wheels.

[0014] The beneficial effects of this utility model's integrated shallow drilling and hammer splitting device are as follows:

[0015] 1. The detection mechanism, drilling mechanism, heavy hammer splitting mechanism, and splitting nail receiving and dispatching mechanism arranged sequentially inside the shell form a series operation module. The physical connection of the mechanical structure eliminates the process intervals between traditional separate equipment. The coaxial layout of the detection mechanism and the drilling mechanism allows the rebar scanning data to directly drive the drilling path correction, avoiding the accumulation of errors from human experience judgment. At the same time, the vertical linkage design of the lifting guide rail and the end gripper enables the automated retrieval of splitting nails, solving the efficiency bottleneck and safety hazards caused by manual insertion and extraction operations.

Detailed Implementation

[0020] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] like Figure 1-3 As shown, a shallow drilling and hammer splitting integrated device includes a housing 100 serving as an installation platform for supporting components. Inside the housing 100, near the forward direction end, is a detection mechanism 200 for detecting the distribution of reinforcing bars within a target location. Behind the detection mechanism 200 is a drilling mechanism 300 for performing fixed-depth drilling operations. Behind the drilling mechanism 300 is a heavy hammer splitting mechanism 400 for splitting shallow concrete. Inside the housing 100, away from the detection mechanism 200, is a splitting nail receiving and dispatching mechanism 500 for storing and transporting splitting nail bodies 800. The end gripper 503 of the splitting nail receiving and dispatching mechanism 500 is located between the drilling mechanism 300 and the heavy hammer splitting mechanism 400.

[0022] In this embodiment, the detection mechanism 200 is located inside the housing 100 near the forward direction end. First, the detection mechanism 200 scans the target object to see if it contains reinforcing bars and the layout of the reinforcing bars, generating safe drilling and splitting coordinates. Second, when the drilling mechanism 300 is aligned with the safe drilling and splitting coordinates, it drills the hole and then retracts. The end gripper 503 is positioned between the drilling mechanism 300 and the hammer splitting mechanism 400, causing the end gripper 503 to convey the splitting nail body 800 to the hole and continue to move so that the hammer splitting mechanism 400 is aligned with the splitting nail body 800, thereby hammering the splitting nail body 800 until it is completely submerged in the hole. This process is repeated until the crushing task of the predetermined area is completed.

[0023] In one embodiment, the detection mechanism 200 includes a rebar scanner 201 and a lifting probe 202. The rebar scanner 201 is disposed at the bottom of the housing 100 near the forward direction end, and the lifting probe 202 is disposed at the bottom of the rebar scanner 201, penetrating the housing 100.

[0024] In this embodiment, the detection mechanism 200 is located in front of the drilling mechanism 300 and is used to detect the reinforcing bars in the target area before drilling. The lifting probe 202 can be raised and lowered in the vertical direction to obtain the distribution information of the reinforcing bars in the target area, avoid accidentally damaging the reinforcing bars during drilling, and improve construction safety and accuracy.

[0025] In one embodiment, the drilling mechanism 300 includes a first hydraulic cylinder 301 and a drilling component 302. The top of the first hydraulic cylinder 301 is fixedly mounted on the housing 100, and the drilling component 302 is provided at the bottom of the first hydraulic cylinder 301. A drill bit 303 is movably mounted at the bottom of the drilling component 302, and the drill bit 303 penetrates the bottom of the housing 100.

[0026] In this embodiment, the first hydraulic cylinder 301 pushes the drill bit 303 to feed vertically, completing the drilling operation at a preset depth on the target concrete structure or rock.

[0027] In one embodiment, the heavy hammer splitting mechanism 400 includes a second hydraulic cylinder 401 and a hammer pressing member 402. The top of the second hydraulic cylinder 401 is fixedly installed on the housing 100, and the hammer pressing member 402 is provided at the bottom of the second hydraulic cylinder 401. A hammer head 403 is movably installed at the bottom of the hammer pressing member 402, and the hammer head 403 penetrates through the bottom of the housing 100.

[0028] In this embodiment, the second hydraulic cylinder 401 drives the hammer head 403 to move in the vertical direction. After drilling is completed and the splitting nail body 800 is inserted, it hammers the nail at a fixed point to provide impact force for the splitting operation.

[0029] In one embodiment, the split nail receiving and dispatching mechanism 500 includes a split nail magazine 501, a material conveying guide rail 502, and an end gripper 503. The split nail magazine 501 is fixedly disposed inside the bottom of the housing 100 away from the detection mechanism 200. One side of the split nail magazine 501 is fixedly connected to one end of the material conveying guide rail 502, and the other end of the material conveying guide rail 502 is fixedly connected to the end gripper 503. A lifting guide rail 504 is disposed next to the end gripper 503, and the end gripper 503 is slidably mounted on the lifting guide rail 504.

[0030] In this embodiment, the split nail bin 501 is used to store multiple split nail bodies 800, the conveying guide rail 502 is used to transport the split nail bodies 800 to the drilling site, or to retrieve the split nail bodies 800 from the drilling site to the split nail bin 501; the end gripper 503 is used to perform the gripping and pulling action on the split nail bodies 800, and the end gripper 503 is driven to move longitudinally by the lifting guide rail 504, thereby realizing the process of pulling out and retrieving the split nail bodies 800.

[0031] In one embodiment, the splitting nail body 800 includes a splitting nail head 801, a connecting block 802, and willow-leaf steel strips 803. Several willow-leaf steel strips 803 are hinged to the outside of the connecting block 802. The willow-leaf steel strips 803 are narrower at the top and wider at the bottom. The splitting nail head 801 is slidably installed on the connecting block 802. The end of the splitting nail head 801 abuts against the inner side of the several willow-leaf steel strips 803.

[0032] In this embodiment, after the splitting nail body 800 is inserted into the drill hole, the willow leaf steel bar 803 opens in a cross direction due to the impact of the heavy hammer splitting mechanism 400, and applies radial splitting force to the hole wall, thereby completing the splitting operation on the target object; and before the splitting operation in the entire area is completed, the splitting nail body 800 will remain in the hole to continuously apply residual stress and improve the splitting effect; until the overall splitting operation is completed, the equipment is operated back to the starting point, and the splitting nail body 800 is pulled out from the hole by the end gripper 503 for recycling.

[0033] In one embodiment, the housing 100 further includes a numerical control system 600 and a hydraulic control system 700. The numerical control system 600 is responsible for executing logical instructions, and the hydraulic control system 700 is used to provide power to each working component.

[0034] In this embodiment, the CNC system 600 is used to coordinate the control logic and sequence of each mechanism, and can calculate and analyze the point relationships and relative positions of the drilling mechanism 300, the placement point of the splitting nail body 800, and the hammer splitting mechanism 400 based on the data provided by the detection mechanism 200, and dynamically adjust the drilling position, depth, placement point, and hammer impact point; the hydraulic control system 700 provides power support for each actuator, realizing integrated control and efficient operation of the equipment.

[0035] In one embodiment, the end gripper 503, which is slidably mounted on the lifting guide rail 504, is positioned at the midpoint between the drilling mechanism 300 and the hammer splitting mechanism 400.

[0036] In this embodiment, by ensuring that the distance between the end gripper 503 and the drilling mechanism 300 and the hammer splitting mechanism 400 is equal, the end gripper 503 simultaneously conveys and places the splitting nail body 800 while the drilling mechanism 300 is drilling, and the hammer splitting mechanism 400 simultaneously impacts the splitting nail body 800, thereby improving the synchronization and efficiency of the equipment.

[0037] In one embodiment, the outer bottom of the housing 100 is provided with a plurality of omnidirectional wheels 900.

[0038] In this embodiment, the omnidirectional wheels 900 are used to drive the equipment to move, thereby realizing automated shallow drilling and splitting operations.

[0039] The present invention and its embodiments have been described above. This description is not restrictive. The accompanying drawings are only one embodiment of the present invention. The actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
