Description

Technical Field

[0001] The invention belongs to the technical field of highway slope construction equipment, and particularly relates to a highway slope grooving device and a grooving depth detection device. Background Art

[0002] The arch-shaped frame slope protection project of expressway slopes is a key technological step in expressway construction. In order to improve the intelligent and information level of highway engineering, realize construction mechanization, reflect the scientific and technological content of civilized construction and technical construction, and thus solve problems such as low construction efficiency and high costs, the mechanization and intelligence of new arch-shaped frame slope protection construction equipment have been studied. At present, electro-hydraulic proportional feedback control is moving towards a new stage of intelligent and refined integration, and the collaborative cooperation between electro-hydraulic proportional feedback control technology and highway construction machinery is an inevitable requirement for the development of the current construction machinery industry.

[0003] The slope grooving operation in highway construction is used for constructing the slope protection project of highway slopes, so as to enhance slope stability, prevent disasters such as landslides or debris flows, and improve the drainage function. At present, during the traditional arch-shaped frame slope protection construction, the base groove excavation process adopts a frame grooving machine in cooperation with manual excavation, which has problems such as high labor intensity, low efficiency, high safety risks, and difficult quality assurance. The grooving operation usually relies on manual measurement and manual depth adjustment. On the one hand, manual operation is extremely time-consuming and laborious. The operator needs to frequently stop the operation to measure the depth, and then manually adjust the grooving equipment according to the measurement results, which undoubtedly greatly slows down the overall construction progress and reduces work efficiency. On the other hand, this mainly manual method is extremely vulnerable to the skill level of the operator. When operated by personnel with different experiences and different skill proficiencies, the obtained grooving depth results may vary greatly. Moreover, the construction environment conditions are complex and changeable, and adverse weather, complex slope terrain, etc. will all interfere with the operator's judgment and operation, thereby resulting in deviations in the grooving depth, making it difficult to meet the precision requirements of slope protection construction, insufficient slope strength, and affecting the safety and long-term use effect of the project. At the same time, during manual operation, the operator needs to be close to the equipment or the working area, which is prone to safety risks in complex terrains and large-scale constructions. Currently, there are already some automated grooving equipment, but most of the equipment still cannot accurately and real-time detect and adjust the grooving depth. Some equipment has a simple depth detection function, but it relies on manual intervention, cannot real-time feedback depth data during construction, and the precision and reliability of most equipment cannot meet the requirements of high-standard construction.

[0004] Currently, highway slope construction equipment has higher and higher requirements for aspects such as slope protection construction precision and efficiency, and needs to adapt to dangerous and harsh working environments. Therefore, intelligence and automation have become the main development trends of construction machinery at present. Summary of the Invention

Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative work all fall within the protection scope of the present invention.

[0023] The specific embodiments of the present invention will be described below with reference to the drawings.

[0024] Embodiment 1

[0025] In order to more clearly illustrate the implementation manners of the present invention, the actual application and effects of the present invention in the grooving operation of highway slopes can be described in detail through two specific application cases. The following are two implementation cases, which respectively show the application of different processes of the device under the construction conditions of highway slope construction.

[0026] It should be noted that in the description terms of the present invention, the orientation or positional relationship indicated by "inside", "interior", "side", "end", "middle", "left and right", "front", "upper", "symmetric", "vertical", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the technical solutions of the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0027] The embodiment of the present application discloses a highway slope grooving device and a grooving depth detection device, as Figures 1 - 5 shown, the grooving depth detection device of the highway slope grooving device includes a main mechanical load-bearing arm 1, a grooving working device 2, an arm sliding seat 3, a mechanical arm base body 4, a main control valve 5 of the hydraulic system, a sensor feedback unit 6 and a computer electric control platform 7.

[0028] AsFigure 2 As shown, the mechanical load-bearing main arm serves as the basic support to ensure the stable operation of the working device. Rack bars 12 are installed on both sides of the arm body of the robotic arm by bolts. The rack and pinion method is adopted to drive the movement of the grooving working device on the main arm, thereby completing the straight grooving on the slope surface by the highway slope grooving equipment.

[0029] As Figure 3 As shown, the grooving working device 2 is composed of a mechanical support arm 21, a working head mounting seat 22, an upper and lower slideway assembly 23, and a milling excavation grooving machine 24. Specifically, the inner arm main frame of the mechanical support arm 21 is a square frame formed by welding four-sided panels. In this example, to increase the strength of the frame, a support frame plate is added inside the frame. The inner arm of the mechanical support arm 21 is designed with a mounting seat for the horizontal telescopic oil cylinder of the support arm. The distal end is welded with an end panel, and bolt holes are evenly distributed around the end panel.

[0030] The basic components of the upper and lower slideway assembly 23 include a welded slideway, a working head telescopic oil cylinder 26, a working head mounting seat 22, and a pin 27. Specifically, the welded slideway includes an upper slideway mounting plate, a hydraulic cylinder vertical plate, and a slideway channel steel. Among them, the upper slideway mounting plate is mechanically welded to the slideway channel steel. The inside of the channel steel is the sliding surface, and the inner groove surface is smooth, without burrs and protrusions. Bolt holes are provided on the upper slideway mounting plate and are bolted to the end panel at the distal end of the inner arm of the mechanical support arm 2. The upper end of the working head telescopic hydraulic cylinder 26 is connected to the hydraulic cylinder vertical plate by a pin 27. The slider of the working head mounting seat 22 is mechanically connected to the inside of the slideway channel steel. The milling excavation grooving machine 24 is fixed to the milling head connecting seat by a pin 25. By driving the working head telescopic hydraulic cylinder 26, the up and down movement of the working head mounting seat 22 in the slideway is driven, thereby realizing the grooving work perpendicular to the slope surface.

[0031] As Figure 4 As shown, the basic components of the support arm sliding seat 3 include a support arm sliding assembly 31 (upper half groove body, lower half groove body), a bottom plate flange, a slewing bearing 32 mounting seat, a support arm slewing reducer 36 mounting seat, and a support arm vertical movement motor reducer 35 mounting seat. Specifically, the mechanical load-bearing main arm 1 is installed in a sleeve frame with a rounded hexagonal cross-section formed by welding the upper and lower half groove plates of the support arm sliding seat. To ensure that the entire grooving working device 2 moves vertically along the mechanical load-bearing main arm 1 and at the same time reduce the overall friction, nylon friction blocks 37 are installed on the four sides inside the sleeve in this example.

[0032] Specifically, the mechanical boom vertical movement drive motor 33 provided on the boom sliding seat 3 is installed on the boom vertical movement motor speed reducer 35 and is mechanically connected to the speed reducer; the mechanical boom rotation drive motor 34 is installed on the boom slewing speed reducer 36 mounting seat and is mechanically connected to the speed reducer. The gear of the boom vertical movement hydraulic motor speed reducer 35 is connected to the rack 12 of the mechanical load-bearing main boom and is used to drive the mechanical boom to move vertically along the mechanical load-bearing main boom; the gear of the mechanical boom slewing speed reducer 36 is connected to the gear of the slewing support 32 and is used to drive the mechanical boom itself to rotate 360°.

[0033] As Figure 5 shown, the mechanical boom base body 4 includes a flange plate 41, a cylinder 42, a friction block 43 and a mechanical boom outer cylinder welding 44. Specifically, the flange plate 41 of the mechanical boom base body is bolted to connect the slewing bearing 31, the slewing speed reducer 36 and the bottom flange of the boom sliding seat 3. In this embodiment, in order to reduce the friction force, reduce wear and extend the service life of each component, nylon friction blocks 43 are respectively assembled on each contact surface.

[0034] Embodiment 2

[0035] The embodiment of the present application discloses a highway slope grooving device and a grooving depth detection device. As Figures 1 - 4 shown, the depth sensor 62 is installed on the working head mounting seat 22 of the milling and digging grooving machine. Specifically, during construction, the operator sets the target depth range of grooving according to the construction requirements (for example: 0.2 meters), and the depth sensor 62 real-time monitors the distance between the milling head and the slope surface. During the grooving process, the operator sends a mechanical boom vertical telescopic control signal to the PLC controller 61, and the PLC controller filters, amplifies and digitizes the data to ensure the accuracy and reliability of the transmitted data. After analyzing and processing the data, the PLC controller sends a duty cycle signal to the hydraulic control valve 5, thereby driving the movement of the working head vertical telescopic hydraulic cylinder 26. In this embodiment, the baud rate of the control system is set to 250 kbit / s.

[0036] In this embodiment, the PLC controller 61 acts as a slave computer to receive the displacement signal of the depth sensor 62. Specifically, the PLC controller 61 uploads the real-time depth data to the remote computer electronic control platform 7 through the wireless communication module, and displays the current grooving depth in real time through the liquid crystal display unit 71 of the computer platform 7. Managers can view the grooving depth and equipment status at any time, realizing real-time monitoring and remote management of slope grooving, ensuring the traceability and safety of project quality, and effectively preventing slope instability problems caused by unqualified depth.

[0037] In this embodiment, the computerized electronic control platform 7 determines the deviation between the current depth and the preset depth based on real-time data. If the depth deviation exceeds the set range, the alarm system 72 will automatically trigger audible and visual warnings to remind the operator to check and adjust the depth. At the same time, the computerized electronic control platform 7 will also feedback the compensation electrical signal to the PLC controller 61 by calling the PID control algorithm. The PLC controller 61 will then optimize the control signal to regulate the working head execution component of the device accordingly. This process repeats in a loop, forming a tight closed-loop feedback chain. Eventually, it drives the working head telescopic hydraulic cylinder to achieve automatic adjustment of the working head displacement, enabling the milling and trenching machine to be adjusted to the predetermined working depth. The computerized electronic control platform 7 is also equipped with an input keyboard and a mouse for the staff to perform tasks such as command output and algorithm application.

[0038] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the application shall be included within the protection scope of the present application.
