Description

Technical Field

[0001] This utility model relates to the field of pile foundation engineering technology, specifically to a drilling device for pile foundation construction. Background Technology

[0002] Specialized drilling equipment for pile foundation construction is mainly used to drill holes at the pile locations in the strata, laying the foundation for subsequent concrete pouring and pile formation. It is a crucial step in pile foundation construction. These equipment use soil extraction or displacement devices to drill holes in various soil layers, ensuring that the diameter, depth, and verticality of the pile holes meet design requirements, thereby guaranteeing the stability and bearing capacity of the pile foundation.

[0003] For example, Chinese Patent Application No. 202322150558.5 discloses a drilling device for pile foundation engineering, including a movable plate with rollers, a vertical plate, a guide slider, a lifting assembly, a rotating shaft, a second motor, a sliding plate, a retaining sleeve, and fastening bolts. The vertical plate is fixed to the movable plate, and a guide groove is provided on the vertical plate. The guide slider is slidably connected to the guide groove. The lifting assembly is located on the vertical plate and is used to drive the guide slider to move up and down. The spiral blades drill a hole in the ground after passing through the retaining sleeve. The spiral blades carry the soil to the upper end of the retaining sleeve, i.e., the sliding plate. After drilling is completed, the fastening bolts are loosened, the retaining sleeve is moved upward, and then the fastening bolts are tightened so that the end of the fastening bolts abuts against the retaining sleeve. The device is then removed, and the soil is removed along with the device, thus ensuring the cleanliness around the hole and preventing soil from entering the hole.

[0004] In pile foundation construction, drilling equipment is often rotated as a whole using tires as a fulcrum for easy pulling and moving. However, due to the large weight of the equipment, the rotation process requires a lot of force, making it quite difficult to operate.

[0005] Therefore, it is necessary to design and modify the drilling equipment used in pile foundation construction to effectively prevent operational difficulties. Utility Model Content

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.

[0023] like Figures 1 to 5As shown, this utility model provides a special drilling equipment for pile foundation construction, including a drilling device 1.

The lifting mechanism includes a fixed plate 4 fixedly connected to the left and right sides of the drilling device 1. A short rod 5 is movably connected to the inner wall of the fixed plate 4 through a bearing. A lifting frame 6 is fixedly connected to the back of the short rod 5. The lifting frame 6 can lift the drilling device 1 upward. A limit return mechanism is provided on the left side of the drilling device 1.

[0025] As a technical optimization of this utility model, by setting a limit and return mechanism, the lifting frame 6 is limited and returned to its original position when flipping up and down, which improves the automation level and ease of operation of the equipment and reduces manual intervention.

[0026] refer to Figure 5 The clutch mechanism includes a transmission rod 10 that is connected to the surface of the lifting device 3. A stabilizing cylinder 11 is sleeved on the left end of the transmission rod 10. A linkage rod 12 is fixedly connected to the left side of the stabilizing cylinder 11. A left clutch gear 13 is fixedly connected to the right side of the stabilizing cylinder 11. A right clutch gear 14 is slidably connected to the surface of the transmission rod 10. When the right clutch gear 14 slides to the left limit position on the surface of the transmission rod 10, it meshes with the left clutch gear 13. At this time, the stabilizing cylinder 11 is driven. A support frame 15 is movably connected to the surfaces of the transmission rod 10 and the linkage rod 12 through bearings. A transmission wheel 16 is fixedly connected to the left end of the linkage rod 12 and the left end of the left short rod 5. A transmission belt 17 is sleeved on the surface of the transmission wheel 16. A control mechanism is provided on the front side of the drilling equipment 1.

[0027] As a technical optimization of this utility model, by setting a clutch mechanism, the power of the transmission rod 10 can be selectively transmitted to the lifting frame 6, improving work efficiency and safety. At the same time, the cooperation of the transmission rod 10, the stabilizing cylinder 11, the linkage rod 12, the transmission wheel 16, and the transmission belt 17 realizes the effective transmission of power, ensuring the stability and reliability of the lifting frame 6.

[0028] refer to Figure 4The control mechanism includes a connecting cylinder 18 fixedly connected to the right side of the right clutch gear 14. A control plate 19 is sleeved on the surface of the connecting cylinder 18. A control frame 20 is slidably connected to the surface of the control plate 19. The back of the control frame 20 is fixedly connected to the front of the support frame 15. A screw 21 is movably connected to the inner wall of the control frame 20 through a bearing. The surface of the screw 21 is threadedly connected to the inner wall of the control plate 19. When the screw 21 rotates, it can drive the control plate 19 to move left and right, thereby controlling the engagement and disengagement of the right clutch gear 14 and the left clutch gear 13.

[0029] As a technical optimization of this utility model, a control mechanism is set up to achieve precise control over the engagement and disengagement of the right clutch gear 14 and the left clutch gear 13. This control method is simple and reliable, and the operator can easily control the lifting and stopping of the drilling equipment 1 by rotating the screw 21, thus improving the ease of operation and accuracy of the equipment.

[0030] refer to Figure 4 A rotating disk 22 is fixedly connected to the left end of the screw 21, and the rotating disk 22 can easily drive the screw 21 to rotate.

[0031] As a technical optimization of this utility model, the rotating disk 22 provides operators with a convenient way to rotate the screw 21. The design of the rotating disk 22 allows operators to easily rotate the screw 21 without the need for tools, further improving the ease of operation of the equipment, reducing the difficulty of operation, and increasing work efficiency.

[0032] refer to Figure 2 Handles 23 are fixedly connected to both the left and right sides of the front of the drilling equipment 1. The handles 23 can easily drive the drilling equipment 1 to rotate.

[0033] As a technical optimization of this utility model, by setting a handle 23, the drilling equipment 1 can be easily pulled and flipped by the lifting mechanism, which improves the practicality of the equipment.

[0034] The working principle and usage process of this utility model are as follows: During operation, the motor 2 drives the lifting device 3, which in turn drives the transmission rod 10 to rotate. When it is necessary to lift the drilling equipment 1, the control mechanism is operated to rotate the screw 21, which drives the control plate 19 to move, allowing the right clutch gear 14 to mesh with the left clutch gear 13. At this time, the power of the transmission rod 10 is transmitted to the linkage rod 12 through the left clutch gear 13 and the stabilizing cylinder 11. The linkage rod 12 drives the left short rod 5 to rotate through the transmission wheel 16 and the transmission belt 17, and the lifting frame 6 on the back of the short rod 5 lifts the drilling equipment 1 upward. During the upward movement of the lifting frame 6, the operator can easily flip the drilling equipment 1 by pulling down the handle 23, allowing it to move using the tires. Then, the control mechanism drives the control plate 19 to return to its original position. At this time, the limit frame 7 of the limit return mechanism plays a limiting role, preventing the lifting frame 6 from returning too far. At the same time, the right clutch gear 14 separates from the left clutch gear 13, and the tension spring 9 pulls the lifting frame 6 back to its original position. The handle 23 on the front of the drilling equipment 1 can be used to easily rotate the drilling equipment 1 when needed. This avoids the inconvenience caused by the laborious rotation of the drilling equipment 1 used in pile foundation construction, and makes it easy to use.

[0035] In summary, when this utility model is used, under the action of the lifting mechanism, the limit return mechanism, the clutch mechanism and the control mechanism, it can assist the drilling equipment 1 to rotate forward, thereby facilitating the pulling of the drilling equipment 1 and avoiding the inconvenience caused by the laborious rotation of the drilling equipment 1 used in pile foundation construction, thus giving it the advantage of being easy to use.
