Technical Field

[0001] The invention belongs to the technical field of anti-slip pile installation, and relates to a rectangular cross-section hole repairing drill bit for anti-slip piles, in particular to a rectangular cross-section hole repairing drill bit for anti-slip piles. Background Art

[0002] Anti-slide piles are widely used in various projects, including slope support, roadbed construction, foundation pit excavation, and tunnel entrance and exit construction, as an effective measure to resist lateral thrust and mitigate engineering and geological hazards. Anti-slide piles are primarily categorized as rectangular or circular cross-section piles. Rectangular cross-section piles are highly favored in many engineering fields due to their high lateral stiffness, high single-pile bearing capacity, and ability to effectively enhance anti-slide resistance and improve the anti-slide coefficient.

[0003] In the prior art, in order to open a rectangular installation hole for an existing rectangular cross-section anti-skid pile drilling construction, a plurality of stacked circular holes are generally drilled on the ground by a drilling rig. When the required size is reached, a rectangular drill bit is used to drill the opened hole to make the hole rectangular. However, during long-term use, the drill wheel of the drill bit is easily deformed, such as when hit by rocks, which affects work efficiency. If the entire wheel is replaced, the cost of use will be greatly increased. Therefore, a rectangular cross-section anti-skid pile drilling drill bit is proposed. Summary of the Invention

[0004] The purpose of the present invention is to address the above-mentioned problems in the existing technology and propose an anti-slip pile rectangular cross-section hole repair drill bit. The technical problem to be solved by this invention is: how to achieve rapid maintenance and inspection of the wheels of the anti-slip pile rectangular cross-section hole repair drill bit to reduce maintenance costs.

[0005] The purpose of the present invention can be achieved through the following technical solutions: The cam is provided with a plurality of drive shafts at two ends, and a drive shaft is provided at two ends of the cam, and each drive shaft is fixedly connected to a drive disk by fixing bolts. The circumferential surface of each drive disk is provided with a drill wheel frame, and the rotation directions of the two drive disks on the same side are opposite. Each drive disk has three fan-shaped slots at equal distances from the outer side of each drive disk, and a limiting mechanism is provided in each fan-shaped slot, and a driving mechanism for driving the limiting mechanism is provided on the outer side of each drive disk. The limiting mechanism includes a U-shaped frame fixedly connected to the fan-shaped slot, a rotating rod is rotatably sleeved in the middle of the U-shaped frame, a circular hole is provided on the U-shaped frame that is adapted for the rotating rod, and the bottom of the rotating rod is fixedly connected to the first rotating rod, and the other end of the first rotating rod is fixedly connected to a clamping rod on the side away from the driving disk, and the other end of the clamping rod is fixedly connected to the limiting block, and the other end of the rotating rod is fixedly connected to the L-shaped rotating rod.

[0006] The working principle of the present invention is: the clamping rods of the three limiting mechanisms rotate on the arc-shaped hole.

In conjunction with the rotation direction of the driving disk, the clamping rod slides to the innermost end of the arc-shaped hole, making the limiting mechanism tighter and prevented from falling.

[0010] With the above structure, the grinding drill bit on the tilted fixed sleeve is replaceable, which is convenient for modifying the drill hole to adapt to the anti-slip pile; The driving mechanism includes a first fixed cylinder fixedly connected to the middle part of the outer side of the driving disk, and a rotating ring is rotatably sleeved on the outer circumferential wall of the first fixed cylinder close to the driving disk, and three vertical holes are equidistantly opened on the circumference of the rotating ring, and one end of each of the L-shaped rotating rods is slidably connected to the adjacent vertical holes; The driving mechanism further includes a second fixed cylinder fixedly connected to the outside of the rotating ring, the inner circumferential wall of the second fixed cylinder is fixedly connected to an internal gear, and the outer circumferential wall of the second fixed cylinder is fixedly connected to an annular oblique locking gear.

[0011] With the above structure, the rotation of the second fixed cylinder drives the L-shaped rotating rods of the three limiting mechanisms to rotate, so that the limiting blocks slide on the arc-shaped holes, thereby achieving the fixation and separation of the drill wheel frame, facilitating the disassembly and installation of the drill wheel frame.

[0012] The outer end of the first fixed cylinder is fixedly connected to a protective ring, and a rotating sleeve on one side of the protective ring is provided with a rotating shaft, and the outer end of the rotating shaft is fixedly connected to a rotating bolt, and a small gear is provided on the fixed sleeve inside the rotating bolt, and the small gear is meshed with the internal gear.

[0013] With the above structure, the second fixed cylinder and the rotating ring of the driving mechanism are driven to rotate by rotating the pinion, thereby realizing control of the limiting mechanism.

[0014] The two slide rods are fixedly connected with the inner wall of the circumference of the drill bit wheel frame, and the other ends of the two slide rods are fixedly connected with protrusions.

[0015] With the above structure, through the setting of the T-shaped inclined clamping block and the spring, after the drill bit wheel frame is connected with the driving disc, in the work, the second fixed cylinder will not loosen and reverse, causing the limiting mechanism to operate, and the drill bit wheel frame is easy to loosen.

[0016] The directions of the drill bit wheel frames of the two driving discs on the same side of the machine body are opposite, a connecting frame is arranged at the middle of the top of the machine body, and a hydraulic connector is arranged at one end of the top of the machine body.

[0017] Compared with the prior art, the rectangular cross-section hole drilling bit for anti-slide pile has the following advantages: 1. In the present application, due to the adoption of the drill bit wheel frame, the arc hole limiting mechanism, the driving mechanism, and the rotating bolt and the pinion, through the rotation of the pinion, the rotating ring of the driving mechanism is rotated, three limiting mechanisms are operated, the drill bit wheel frame is quickly fastened or separated, the drill bit wheel frame is convenient to replace, the problem in the background art is effectively solved, and the convenient replacement of the drill bit wheel frame is realized, the equipment downtime maintenance time is reduced, the maintenance efficiency of the hole drilling bit is improved, the use cost is reduced, the risk of project delay caused by component replacement is reduced, and the overall construction efficiency is improved.
