The support mechanism includes a support plate disposed on the back of the spiral drilling rod. The support plate is slidably connected inside the main frame, supporting the spiral drilling rod. A movable plate is mounted above the support plate and slidably disposed inside the main frame, used to move the support plate. A hydraulic telescopic device is installed inside the main frame, above the movable plate. This drilling device for municipal public works construction allows for two different modes of movement of the spiral drilling rod by releasing or fixing the connection between the movable plate and the support plate, making the movement of the spiral drilling rod more stable and flexible.

[0004] When using the above-mentioned technology, the following technical problems were found in the existing technology: Due to the limited bottom support area of ​​the frame, multiple people are required to maintain the stability of the device during actual drilling. While a larger frame can improve stability, it increases the size and weight of the device, making it inconvenient to move and transport. In addition, during drilling, the drilling device needs to be aligned with the drilling point, but since the drilling component is suspended in the air before drilling, it is necessary to repeatedly raise and lower the drilling component or move the device when aligning it with the drilling point. To address these issues, a drilling device for municipal public works construction is designed to provide an alternative technical solution. Utility Model Content

[0005] Therefore, it is necessary to provide a drilling device for municipal public works construction that can improve the stability of the drilling device and facilitate quick alignment of drilling points without excessively increasing its size, in order to address the aforementioned technical problems.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0032] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0033] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0034] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0035] like Figure 1 As shown, this drilling device for municipal public works construction includes a base 1, a drilling assembly 2, a frame 3, a lifting mechanism 4, a set of support mechanisms 5, and a positioning mechanism 6. The lifting mechanism 4 is mounted on the base 1 via the frame 3 and is used to adjust the height of the drilling assembly 2. The drilling assembly 2 is mounted on the lifting mechanism 4 and, driven by the lifting mechanism 4, contacts the drilling point to perform the drilling operation. The frame 3 serves as a supporting component of the overall structure, ensuring the stability of the device and the accuracy of the drilling. The support mechanisms 5 are located on both sides of the base 1 and provide additional support during the drilling process to prevent the device from shaking. The positioning mechanism 6 assists the drilling assembly 2 in accurately aligning with the drilling point, ensuring the accuracy and efficiency of the drilling.

[0036] The base 1 is further composed of a set of first rods 11 and a set of second rods 12 fixed between the first rods 11. Specifically, the first rods 11 and the second rods 12 together constitute the main structure of the base 1, providing a stable support foundation. The first rods 11 are long strip structures extending along the length of the base 1, used to bear the longitudinal force generated by the drilling device during operation. The second rods 12 are staggered with the arrangement of the first rods 11 and connected between the first rods 11, forming lateral and longitudinal supports, enhancing the torsional strength and stability of the base 1. Thus, the base 1 can withstand a large drilling reaction force, ensuring the smooth progress of drilling operations. In addition, the first rods 11 and the second rods 12 are preferably made of high-strength steel to ensure that the base 1 has sufficient strength and durability.

[0037] like Figure 2 As shown, and for reference Figure 1 The drilling assembly 2 further includes a base 21, a drilling component 22, and a drive component 23. Specifically, the base 21 serves as the mounting base for the drilling component 22 and the drive component 23. The drilling component 22 is rotatably connected to the base 21 and is responsible for performing the actual drilling operation. The drive component 23 is fixed to the base 21 and coaxially connected to the drilling component 22 (coupling connection), providing the necessary rotational power to the drilling component 22. The drive component 23 drives the drilling component 22 to rotate, and the rotating drilling component 22 contacts the hole opening point to realize the drilling operation.

[0038] The drive unit 23 can be an electric motor or a small single-cylinder gasoline engine as shown in the figure; both the electric motor and the small single-cylinder gasoline engine have sufficient power output to meet the drilling requirements of different materials and depths. The advantages of the electric motor are its smooth operation and low noise, making it suitable for indoor use or construction sites requiring a low-noise environment. The small single-cylinder gasoline engine, on the other hand, is more suitable for outdoor construction sites or construction sites far from power sources due to its portability and lack of power supply limitations. Thus, the appropriate type of drive unit 23 can be flexibly selected according to the specific construction environment and requirements to ensure the efficient operation of the drilling device and the smooth completion of the drilling operation.

[0039] The drilling component 22 can be in the shape of a helical shaft as shown in the figure. This helical shaft-shaped component 22 helps to effectively remove soil or material from the drilling area during the drilling process, reducing drilling resistance and improving drilling efficiency. Because the helical blades of the helical shaft generate a certain propulsive force when rotating, the drilling component 22 can penetrate deep into the soil or material. Simultaneously, the rotation of the helical blades can push drilling debris or soil upwards, facilitating cleaning and removal. This design is particularly suitable for municipal public works projects requiring drilling into harder soil or materials, significantly improving construction efficiency and drilling quality.

[0040] The drilling component 22 can also be a hollow drill bit, which enables efficient drilling operations in concrete. Compared to a spiral-shaped drilling component 22, the hollow drill bit has a cavity at its center, which helps reduce heat accumulation during drilling and avoids damage caused by overheating. Furthermore, the hollow drill bit can quickly and accurately penetrate hard materials such as concrete through its sharp cutting edges, greatly improving drilling efficiency and quality. Based on the above, the type of drilling component 22 can be selected according to actual use, thereby meeting complex and varied construction needs.

[0041] like Figure 3 As shown, and for reference Figure 1 and Figure 2 The lifting mechanism 4 includes a set of guide parts 41 that restrict the vertical sliding of the base 21, and a moving part 42 that can drive the base 21 to slide vertically on the set of guide parts 41.

[0042] The lifting mechanism 4 is further composed of a set of guide parts 41 and a moving part 42. Specifically, since the set of guide parts 41 is connected to both the drilling assembly 2 and the moving part 42, when the moving part 42 is activated, it can drive the drilling assembly 2 to slide smoothly and precisely vertically along the path set by the guide parts 41, thereby adjusting the height of the drilling part 22 to control the drilling depth of the drilling part 22.

[0043] Based on the above, each set of guide sections 41 is further composed of guide posts 411 and sliding sleeves 412. Specifically, the guide post 411, as the main guiding element, has its two ends fixedly connected to the first rod 11 and the frame 3, respectively, ensuring the stability of the structure and the accuracy of the guidance. The sliding sleeve 412 is slidably fitted onto the guide post 411 and fixedly connected to the base 21. This design allows the base 21 to slide smoothly vertically under the guidance of the guide post 411.

[0044] The moving part 42 further includes a threaded rod 421, a handwheel 422, and a nut 423. Specifically, the threaded rod 421 serves as the main transmission element, with one end rotatably connected to the second rod 12 and the other end passing through the frame 3 and fixedly connected to the handwheel 422. Rotating the handwheel 422 drives the threaded rod 421 to rotate. Since the nut 423 is threadedly connected to the threaded rod 421 and fixedly connected to the base 21, when the threaded rod 421 rotates, due to the threaded engagement between the nut 423 and the threaded rod 421, the nut 423 moves along the axial direction of the threaded rod 421, thereby causing the base 21 and the drilling component 22 mounted on the base 21 to slide vertically, allowing the drilling component 22 to contact the drilling point for drilling operations. It should be noted that the moving part 42 includes, but is not limited to, the structure shown above; it can also be a drive element such as an electric push rod or a cylinder, as long as it can achieve the vertical sliding of the base 21 and the drilling component 22.

[0045] like Figure 4 As shown, and for reference Figure 1 Each set of support mechanisms 5 further includes a third rod 51, a first limiting member 52, and a second limiting member 53. Specifically, one end of the third rod 51 is rotatably connected to one side of the first rod 11, and the other end is a free end that serves as a support point. The first limiting member 52 is disposed between the third rod 51 and the base 1. The first limiting member 52 is used to drive the third rod 51 to rotate to form a certain angle with the base 1 and keep the third rod 51 in an open state, thereby increasing the contact area between the base 1 and the ground and improving the stability of the entire drilling device.

[0046] The second limiting member 53 is located between the third rod 51 and the first rod 11. When the support mechanism 5 needs to be folded, the second limiting member 53 is operated so that the third rod 51 can fit against the first rod 11 to form a folded state, so as to facilitate the carrying and storage of the entire drilling device.

[0047] The first limiting member 52 is further a gas spring 521. When the third rod 51 is attached to the first rod 11, the gas spring 521 is in a compressed state and hinged between the first rod 11 and the third rod 51. When the support mechanism 5 needs to be unfolded, by releasing the compressed state of the gas spring 521, the gas spring 521 automatically extends and pushes the third rod 51 away from the first rod 11 until the third rod 51 forms a predetermined support angle with the base 1. At this time, the internal pressure of the gas spring 521 maintains the opening angle of the third rod 51, thereby effectively increasing the contact area between the drilling device and the ground and improving the stability of the device.

[0048] The second limiting member 53 is at least one magnet 531. The magnet 531 is fixed on the adjacent side of the first rod 11 and / or the third rod 51. When the support mechanism 5 needs to be folded, the operator only needs to apply force to retract the gas spring 521 to bring the third rod 51 into contact with the first rod 11. Under the action of the magnet 531, the third rod 51 is magnetically attached to the first rod 11, thereby folding the third rod 51 to the first rod 11. This prevents the third rod 51 from opening due to accidental collision during carrying or storage, and enhances the stability of the folded state. The folded drilling device is small in size, occupies less space, and is more convenient for transportation and storage.

[0049] like Figure 5 As shown, and for reference Figure 1The positioning mechanism 6 further includes an aiming plate 61, a set of connecting plates 62, a base plate 63, a slide groove 64, a target area 65, and an idle area 66. Specifically, the base plate 63 is fixed between a set of first rods 11 by a set of connecting plates 62 on both sides. The slide groove 64 is formed on the base plate 63, so that the aiming plate 61 can slide in the slide groove 64. The setting of the slide groove 64 enables the aiming plate 61 to move accurately along the length direction of the base plate 63, ensuring that the drilling assembly 2 can accurately position the pre-drilling point.

[0050] The slide 64 is further composed of a target area 65 and an idle area 66 that are interconnected. The target area 65 is used so that when the aiming plate 61 slides into this area, it is on the same vertical axis as the drilling assembly 2. By observing whether the aiming plate 61 located in the target area 65 coincides with the drilling point, it can be known that the drilling assembly 2 is vertically aligned with the drilling point. If aligned, the aiming plate 61 is then pulled to the idle area 66. At this time, the aiming plate 61 will not interfere with the normal operation of the drilling assembly 2. Finally, the drilling assembly 2, driven by the lifting mechanism 4, passes through the target area 65 to accurately drill the drilling point, thereby improving the accuracy and efficiency of drilling.

These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
