Description

Technical Field

[0001] This utility model relates to the field of drill bit technology, and more specifically, to a modular, spliced ​​square drill bit for anti-slip piles. Background Technology

[0002] Anti-slide piles are widely used in highways, municipal works, foundation pits and other fields. Anti-slide piles are reinforced concrete cylindrical or rectangular cubic structures that resist the sliding force of rock and soil. They are mainly used for rock and soil with poor stability to ensure the stability of slopes, foundation pits and other structures.

[0003] The construction sequence for anti-slide piles is mechanical drilling (or manual excavation) → retaining wall construction → lowering the reinforcing cage → pouring concrete. Circular and rectangular cross-section anti-slide piles each have distinct advantages and disadvantages. Circular cross-section anti-slide piles offer faster construction speeds and are suitable for landslide emergency rescue projects. However, according to mechanical analysis, under the same cross-sectional area and reinforcement conditions, circular piles exhibit significantly lower shear resistance and stress conditions compared to rectangular cross-section anti-slide piles, making rectangular cross-section anti-slide piles more effective in retaining force. Especially in landslide treatment projects, where there is often a large sliding thrust, circular anti-slide piles may not meet the required retaining force or be economically inefficient; large-sized rectangular anti-slide piles are necessary to fulfill the anti-slide retaining function. While rectangular cross-section anti-slide piles offer clear stress distribution and good shear resistance, limitations in drilling machinery prevent direct mechanical drilling of square holes. Manual excavation is typically used, which suffers from drawbacks such as hole collapse, slow progress, significant safety hazards for construction workers, and the long-term excavation of large open areas on the landslide body is detrimental to landslide treatment projects.

[0004] Therefore, a modular, spliced ​​square drill bit for anti-slide piles is proposed. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a modularly spliced ​​square drill bit for anti-slide piles to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a modular anti-slide pile square drill bit, comprising a bottom shell, a top cover installed on the top of the bottom shell, a connecting frame welded on the top cover, a fixing flange welded to the top of the connecting frame, a drive mechanism installed on the top cover, symmetrically installed shaft frames inside the bottom shell, a transmission component meshing with the drive mechanism installed in the middle of each shaft frame, rotating components meshing with both sides of each transmission component, a first drill body installed at one end of each rotating component, follower bevel gears meshing with both sides of the bottom end of the drive mechanism, each follower bevel gear coaxially connected to a shaft rotatably mounted on the bottom shell, and a second drill body installed at the end of each shaft. The four first drill bodies and the two second drill bodies together form a square structure.

[0007] Preferably, the drive mechanism includes a motor, a drive rod, and a drive gear. The motor is mounted on the top cover, and the output end of the motor is connected to a drive rod inserted into the bottom shell. The drive rod has a drive gear installed at its end.

[0008] Preferably, the transmission assembly includes a transmission rod, a transmission bevel gear, and a transmission gear disc. The transmission rod is rotatably mounted on a shaft frame. One end of the transmission rod is equipped with a transmission bevel gear that meshes with a drive gear. A transmission gear disc is coaxially arranged on one side of the transmission bevel gear. Rotating components are meshed on both sides of the transmission gear disc.

[0009] Preferably, the rotating structure includes a follower rod and a follower gear disk. One end of the follower rod is rotatably connected to the shaft frame, and the other end of the follower rod passes through the bottom shell and is connected to the second drill body. A follower gear disk that meshes with the transmission gear disk is coaxially mounted on the follower rod.

[0010] Preferably, the shaft frame includes a support portion and a pressing portion. The support portion is welded to the bottom end inside the bottom shell, the pressing portion is bolted to the top end of the support portion, and multiple bearings are fixed between the support portion and the pressing portion.

[0011] Preferably, multiple dials are welded to the outer surfaces of both the first and second drill bodies.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] The drive mechanism drives each drill body to rotate synchronously, making the drilled square holes more standardized and improving drilling efficiency and convenience.

[0014] The motor-driven design enables the combination drill bit to have its own drive function, reducing the transmission arm, increasing the transmission force, and thus improving the drilling effect.

[0015] The shaft bracket supports the transmission rod and follower rod, which are connected by bearings, improving rotational smoothness, reducing friction, extending service life, and also reducing noise.

[0016] The cutting head on the outer surface of the first and second drill bodies can reduce the stress surface of the soil, making it easier to drill and push the drilled soil upwards, which is convenient for cleaning and helps to improve drilling efficiency. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] As attached Figures 1-5 The assembled anti-slide pile square drill bit shown includes a bottom shell 1, a top cover 2 installed on the top of the bottom shell 1, a connecting frame 3 welded on the top cover 2, a fixing flange 4 welded on the top of the connecting frame 3, a drive mechanism 5 installed on the top cover 2, shaft frames 10 symmetrically installed inside the bottom shell 1, a transmission component 11 meshing with the drive mechanism 5 installed in the middle of each shaft frame 10, a rotating component 12 meshing with both sides of each transmission component 11, a first drill body 6 installed at one end of each rotating component 12, a follower bevel gear 9 meshing with both sides of the bottom end of the drive mechanism 5, a shaft 8 rotatably mounted on the bottom shell 1 coaxially connected to each follower bevel gear 9, and a second drill body 7 installed at the end of each shaft 8. The four first drill bodies 6 and the two second drill bodies 7 together form a square structure.

[0025] In practice, the drive mechanism 5 drives the following bevel gears 9 and the transmission assembly 11 to rotate. The following bevel gears 9 drive the second drill body 7 installed at the end of the shaft 8 to rotate. The transmission assembly 11 drives the rotating assemblies 12 on both sides to rotate, so that the first drill body 6 rotates accordingly. This allows the first drill body 6 and the second drill body 7 to rotate synchronously, enabling drilling operations on the square holes of the anti-slip piles. This makes the drilled square holes more standardized and improves drilling efficiency and convenience.

[0026] The drive mechanism 5 includes a motor 501, a drive rod 502 and a drive gear 503. The motor 501 is mounted on the top cover 2. The output end of the motor 501 is connected to the drive rod 502 inserted into the bottom shell 1. The drive gear 503 is installed at the end of the drive rod 502.

[0027] In practice, the motor 501 operates, causing the drive rod 502 to rotate, which in turn drives the drive gear 503 to rotate, so that the combined drill bit has its own drive function. This eliminates the need for a separate drive design in the drilling equipment, reduces the transmission arm, increases the transmission force, and thus improves the drilling effect.

[0028] The transmission structure 11 includes a transmission rod 1101, a transmission bevel gear 1102, and a transmission gear disk 1103. The transmission rod 1101 is rotatably mounted on the shaft frame 10. One end of the transmission rod 1101 is equipped with a transmission bevel gear 1102 that meshes with the drive gear 503. A transmission gear disk 1103 is coaxially arranged on one side of the transmission bevel gear 1102. Rotating components 12 are meshed and connected to both sides of the transmission gear disk 1103.

[0029] In specific implementation, the drive gear 503 meshes with the transmission bevel gear 1102 to rotate, thereby causing the transmission gear disk 1103, which is coaxially mounted on the transmission rod 1101, to rotate. This drives the rotating component 12 to rotate, so that the second drill body 7 can rotate. Through the setting of the transmission component 11, two second drill bodies 7 can be driven to rotate simultaneously, improving the transmission effect and the rationality of the position arrangement of the second drill bodies 7.

[0030] The rotating assembly 12 includes a follower rod 1201 and a follower gear disk 1202. One end of the follower rod 1201 is rotatably connected to the shaft frame 10, and the other end of the follower rod 1201 passes through the bottom shell 1 and is connected to the second drill body 7. The follower gear disk 1202, which meshes with the transmission gear disk 1103, is coaxially mounted on the follower rod 1201.

[0031] In practice, the transmission gear 1103 meshes with the follower gear 1202 to rotate, thereby enabling the follower rod 1201 to drive the second drill body 7 to rotate.

[0032] The shaft frame 10 includes a support part and a pressing part. The support part is welded to the bottom of the inner shell 1, and the pressing part is bolted to the top of the support part. Multiple bearings are fixed between the support part and the pressing part.

[0033] In practice, the transmission rod 1101 and the follower rod 1201 are connected to the bearing respectively, which can improve the smoothness of rotation, reduce friction, increase service life, and also reduce noise.

[0034] Multiple dials are welded to the outer surfaces of both the first drill body 6 and the second drill body 7.

[0035] In practice, by making contact with the soil, the stress surface can be reduced, making it easier to drill through the soil. At the same time, depending on the direction of the drill bit, the drilled soil can be pulled upwards to facilitate soil removal during the drilling process with other equipment, and also to improve drilling efficiency.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
