Description

Technical Field

[0001] This invention relates to the field of drilling construction technology, and in particular to integrated drilling and installation equipment and construction methods for concrete guardrails. Background Technology

[0002] With the rapid development of transportation infrastructure and the increasing density of highway and railway networks, traffic noise pollution has become a more prominent problem. Concrete guardrail sound barriers, with their excellent sound insulation performance, high strength, and long lifespan, have become the preferred solution for noise reduction projects. However, traditional drilling construction suffers from the following technical bottlenecks: low efficiency, single-machine operation per hole, difficulty in multi-machine coordination, long shift waiting times, large manual positioning errors, and difficulty in meeting millimeter-level installation requirements for hole position deviation and verticality. Furthermore, drilling equipment often encounters reinforcing bars during construction, and current propulsion devices cannot detect the presence of these bars, leading to drill bit breakage and high drilling noise. Moreover, high-altitude operations rely on manual lifting of equipment, resulting in serious dust and noise hazards; traditional impact drills generate noise levels as high as 105 dB, and wastewater and waste residue treatment is often inadequate. When operating on viaducts, the noise generated by concrete drilling severely impacts the surrounding living environment. Therefore, this paper proposes an integrated drilling and installation equipment and construction method for concrete guardrails. Summary of the Invention

[0003] The purpose of this invention is to solve the problems existing in the prior art, and to propose an integrated drilling and installation equipment and construction method for concrete guardrails.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An integrated drilling and installation equipment and method for concrete guardrails includes an integrated construction device mounted on a vehicle body and towed by the device. The integrated construction device includes a balancing construction seat with a V-shaped positioning port at the bottom. A following component is provided at the bottom of the balancing construction seat. Balance measurement components that abut against the concrete guardrail are provided on both sides of the inner wall of the V-shaped positioning port. An upper mounting frame and a side mounting frame are provided on the balancing construction seat. Drilling machinery is mounted on the upper mounting frame and the side mounting frame via a propulsion device. A pressure testing component is installed at the drill bit connection end of the drilling machinery for measuring drilling pressure. The side wall of the balancing construction seat is provided with a counterweight balancing platform, the counterweight balancing platform is provided with a balancing cylinder, the output end of the balancing cylinder is connected to a support frame, and a water supply tank with a water supply pump is provided on the support frame.

[0005] As a preferred embodiment, the propulsion device includes a mounting base, on which a propulsion hydraulic push rod is provided. The output end of the propulsion hydraulic push rod is connected to a drilling rig assembly plate, and the drilling machinery is integrated on the drilling rig assembly plate.

[0006] As a preferred embodiment, the pressure testing assembly includes a torque transmission sleeve disposed at the output end of the drilling machinery, on which a drill bit is replaceably and detachably mounted, and on which a pressure sensor for detecting the pressure of the drill bit is disposed.

[0007] As a preferred embodiment, the balance measurement component includes a balance slide groove formed on the inclined inner wall of a V-shaped positioning port, a resistance rail is provided in the balance slide groove, a conductive collar is slidably arranged on the resistance rail, the conductive collar is connected to a storage spring seat, the storage spring seat is connected to the inner wall of the balance slide groove through a bearing spring, and an inclined pressure plate is fixedly connected to the storage spring seat.

[0008] As a preferred embodiment, the following travel component includes a lifting hydraulic cylinder installed above the balance construction seat. The output end of the lifting hydraulic cylinder extends through a V-shaped positioning port and is fixedly connected to a lifting plate. A following wheel is provided at the bottom of the lifting plate.

[0009] As a preferred embodiment, the counterweight balancing platform is provided with a fixed sliding plate, and the support frame is provided with a matching sliding opening adapted to the fixed sliding plate.

[0010] The construction method proposed by the integrated drilling and installation equipment for concrete guardrails includes the following construction steps: S1. Construction equipment assembly: Install the V-shaped positioning port at the bottom of the balance construction seat onto the upper edge of the concrete guardrail. Under the weight of the equipment, the side wall of the upper edge of the concrete guardrail will come into contact with the inclined pressure plate inside the V-shaped positioning port. S2. On-site survey and positioning: During the movement, control the lifting hydraulic cylinder to drive the following wheel to extend downward and contact the concrete guardrail. The integrated construction device is supported by the following wheel and moved on the concrete guardrail by the vehicle body to pull the integrated construction device. During the movement, stop at the location where drilling is required and make fine adjustments to the integrated construction device. After the drilling location is determined, release the supporting force of the lifting hydraulic cylinder so that the V-shaped positioning port contacts the concrete guardrail. S3, Angle Calibration: The flatness of the balancing construction seat is detected by the balance measurement component set in the V-shaped positioning port. When the balancing construction seat is found to be not level, the horizontal distance of the inner support frame is changed to control the levelness of the balancing construction seat. S4. Adaptive propulsion drilling: The drilling machine is propelled by the propulsion device. During the movement of the drilling machine, the change of its center of gravity is measured in real time by the balance measurement component set on the balance construction seat. When the balance threshold is triggered, the balance cylinder is controlled to control the corresponding movement of the support frame to achieve adaptive balance. S5. Rebar Obstruction Detection Self-Adjustment: During the drilling process, when the drill bit at the end of the drilling machine contacts the rebar, the drilling progress will increase the pressure of the pressure sensor. At this time, the propulsion device is triggered to reduce the propulsion speed, thereby reducing noise generation from the source.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention uses a vehicle-mounted integrated construction device to control the travel distance to achieve precise control of hole spacing, avoiding manual positioning deviation. The balance is monitored in real time by the resistance rail and current sensing system in the V-shaped positioning port, and the position of the load-bearing frame used for counterweight is dynamically adjusted by the balance cylinder to ensure that the drilling is horizontal throughout, fundamentally solving the problem of hole verticality deviation.

[0012] 2. This invention monitors sudden changes in resistance through a pressure sensor at the drill bit end. When encountering steel bars, the resistance increases, and the drilling speed is automatically reduced to avoid drill breakage. The drilling speed is adaptively adjusted according to the material hardness, reducing construction noise from 105dB to below 75dB. The integrated water supply tank suppresses dust, wastewater and waste residue are centrally recycled to prevent bridge surface pollution, and automated equipment replaces manual lifting, eliminating the risk of falls from heights and the harm of dust and noise.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0017] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0018] Example, refer to Figures 1 to 7This is an integrated drilling and installation equipment for concrete guardrails. It includes an integrated construction device mounted on a vehicle that is towed and moved. The vehicle is a construction vehicle that uses a towing device to move the integrated construction device across the concrete guardrail, thereby drilling holes at corresponding locations one by one. The spacing can be controlled by adjusting the distance the vehicle travels. The integrated construction device includes a balancing construction seat 1 with a V-shaped positioning port 2 at its bottom. A following travel component is installed at the bottom of the balancing construction seat 1, including a lifting hydraulic cylinder 21 mounted above the balancing construction seat 1. The output end of the lifting hydraulic cylinder 21 extends into the V-shaped positioning port 2 and is fixedly connected to the lifting plate 22. The bottom of the lifting plate 22 is equipped with a following wheel 23. It should be noted that during the drilling process, the lifting plate 22 is in a retracted state. At this time, the V-shaped positioning port 2 is locked onto the concrete guardrail. It is connected to the concrete guardrail through the balance measuring component. During the walking phase, the lifting hydraulic cylinder 21 moves downward to drive the lifting plate 22 to contact the concrete guardrail, thereby enabling the following wheel 23 to support the integrated construction device and switch the positioning state to the walking state.

[0019] The inner walls of the V-shaped positioning port 2 are provided with balance measuring components that abut against the concrete guardrail. The balance measuring components include a balance slide 16 opened on the inclined inner wall of the V-shaped positioning port 2, a resistance rail 17 is provided in the balance slide 16, a conductive collar 18 is slidably arranged on the resistance rail 17, a storage spring seat 19 is connected to the storage spring seat 19, the storage spring seat 19 is connected to the inner wall of the balance slide 16 through a bearing spring, and an inclined pressure plate 20 is fixedly connected to the storage spring seat 19. It is worth noting that the conductive collar 18 transmits electrical signals through the resistive rail 17. When the length of the resistive rail 17 changes, the resistance changes. Therefore, the change in the length of the resistive rail 17 can be detected by the current sensing sensor. When the balance construction seat 1 is in a horizontal state, the current intensity on both sides is the same. When the current is not the same, it can be determined that the balance construction seat 1 is in a tilted state, and the tilt angle is towards the side with the smaller current. By detecting the current value, the balance cylinder 7 can be controlled to adjust the load-bearing frame 8 used for counterweight movement, thereby achieving the effect of real-time adjustment of the level.

[0020] The balance construction seat 1 is equipped with an upper mounting frame 3 and a side mounting frame 4. The upper mounting frame 3 and the side mounting frame 4 are equipped with drilling machinery 5 through a propulsion device. The propulsion device includes a mounting base 10. The mounting base 10 is equipped with a propulsion hydraulic push rod 11. The output end of the propulsion hydraulic push rod 11 is connected to a drilling rig assembly plate 12. The drilling machinery 5 is integrated on the drilling rig assembly plate 12.

[0021] Among them, the drilling machine 5 located at the top is in a vertical downward state, while the drilling machine 5 located on the side is in a horizontal state. Therefore, during the drilling process, it is only necessary to ensure that the balance construction seat 1 is in a horizontal state to ensure the perpendicularity of the drilling machine 5 to the drilling surface.

[0022] A pressure testing assembly is installed at the connection end of the drill bit 14 on the drilling machine 5 to measure the drilling pressure. The pressure testing assembly includes a torque transmission sleeve 13 set at the output end of the drilling machine 5. The drill bit 14 is replaceably and detachably installed on the torque transmission sleeve 13. A water spray device is set at the drill bit 14. A pressure sensor 15 for detecting the pressure of the drill bit 14 is set on the torque transmission sleeve 13. The drilling speed and the material being drilled will also cause noise. Therefore, when drilling into the steel bars in the concrete guardrail, its existing propulsion balance will be disrupted, causing the drill bit 14 to generate increased resistance. The increased resistance of the drill bit 14 will be sensed by the pressure sensor 15. When the pressure increases, the propulsion device will be automatically controlled to reduce the propulsion speed, thereby achieving the effect of automatically adjusting the drilling rate according to different materials, reducing noise generation, and avoiding damage to the drill bit 14.

[0023] The side wall of the balancing construction seat 1 is equipped with a counterweight balancing platform 6, and a balancing cylinder 7 is installed on the counterweight balancing platform 6. The output end of the balancing cylinder 7 is connected to a support frame 8. A water supply tank 9 equipped with a water supply pump is installed on the support frame 8. The water supply tank 9 is equipped with a water supply pump inside, which serves as a water transfer station. The water in the water supply tank 9 is always full. A water pool is installed on the vehicle body to supply water to the water supply tank 9 in real time, so as to ensure that the weight on the support frame 8 does not change at all times. A fixed sliding plate 24 is installed on the counterweight balancing platform 6, and a matching sliding mouth adapted to the fixed sliding plate 24 is opened on the support frame 8 for supporting the support frame 8.

[0024] During the drilling process, the perpendicularity of the drill bit 14 has a significant impact on noise. At the same time, the drilling speed and the material being drilled also contribute to noise generation.

[0025] The construction method for integrated drilling and installation of concrete guardrails includes the following steps: Construction equipment assembly: Install the V-shaped positioning port 2 at the bottom of the balance construction seat 1 onto the upper edge of the concrete guardrail. Under the action of the equipment's gravity, the side wall of the upper edge of the concrete guardrail will come into contact with the inclined pressure plate 20 inside the V-shaped positioning port 2. On-site survey and positioning: During the movement, control the lifting hydraulic cylinder 21 to drive the following wheel 23 to extend downward and contact the concrete guardrail. The following wheel 23 supports the integrated construction device, and the vehicle body pulls the integrated construction device to move on the concrete guardrail. During the movement, stop at the location where drilling is required, and make fine adjustments to the integrated construction device. After the drilling location is determined, release the supporting force of the lifting hydraulic cylinder 21 so that the V-shaped positioning port 2 contacts the concrete guardrail. Angle calibration: The flatness of the balance construction seat 1 is detected by the balance measurement component set in the V-shaped positioning port 2. When the balance construction seat 1 is found to be not level, the horizontal distance of the inner support frame 8 is changed to control the levelness of the balance construction seat 1. Adaptive propulsion drilling: The drilling machine 5 is propelled by a propulsion device. During the movement of the drilling machine 5, the change in its center of gravity is measured in real time by the balance measurement component set on the balance construction seat 1. When the balance threshold is triggered, the balance cylinder 7 is controlled to move the support frame 8 accordingly to achieve adaptive balance. That is, when the propulsion device drives the drilling machine 5 to move inward, the balance construction seat 1 will be triggered to be disrupted. At this time, the balance measurement component measures whether the balance is broken. When the balance is broken, the output end of the balance cylinder 7 is controlled by an electrical signal to drive the support frame 8 to move inward, thereby compensating for the balance of the balance construction seat 1 and ensuring the balance during the drilling process when the propulsion device drives the drilling machine 5 to move, that is, ensuring the verticality of the drilling machine 5. Rebar obstruction detection self-adjustment: During the drilling process, when the drill bit 14 at the end of the drilling machine 5 comes into contact with the rebar, the drilling progress will cause the pressure of the pressure sensor 15 to increase. At this time, the propulsion device is triggered to reduce the propulsion speed, thereby reducing the generation of noise from the source.

[0026] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
