DETAILED DESCRIPTION

[0016] In order for those skilled in the art to better understand the technical solutions of the present application, the present application will be further described in detail below with reference to the drawings.

[0017] Please refer to Figures 1-8 The high-efficiency rotating-in equipment for group anchor foundation construction provided by the embodiment of the present application is mainly suitable for group anchor foundation construction and can also be used for single anchor foundation construction, and mainly comprises a base 1, a moving platform 2, a rotary drilling machine 3, a docking assembly 4 and a storage assembly 5.

[0018] The base 1 is installed on the bottom surface of the anchor group construction area. The base 1 includes a first track 11 and a second track 13. There are two sets of second tracks 13 arranged in parallel alignment. The moving platform 2 is slidably connected to the first track 11 along the first horizontal direction. Slides are fixedly installed at both ends of the first track 11. The two slides are slidably connected to the two second tracks 13 in a one-to-one correspondence. The sliding direction is the second horizontal direction, which is perpendicular to the first horizontal direction. A first screw 12, parallel to each other, is rotatably connected to the first track 11. The moving platform 2 is screwed to the first screw 12 through a threaded hole on the track 11. A second screw 14, parallel to each other, is rotatably connected to one of the second tracks 13. A slide is threaded to the second screw 14 through a threaded hole on the slide 13. A track motor 15 is installed on the first track 11 and one of the second tracks 13 respectively. The track motor 15 on the first track 11 is used to drive the first screw 12 to rotate, thereby driving the moving platform 2 to move along the first horizontal direction. The track motor 15 on the second track 13 is used to drive the second screw 14 to rotate, thereby driving the first track 11 to move along the second horizontal direction.

[0019] As a further preferred technical solution, two second screws 14 are rotatably connected to the two second tracks 13 respectively. Correspondingly, the two slides are threadedly connected to one of the second screws 14 through the threaded holes on them. The two second screws 14 are connected by a coupling 16, so that the track motor 15 on the second track 13 can drive the two second screws 14 to rotate synchronously, so that the two slides have the power to move on their respective second tracks 13.

[0020] The rotary drilling rig 3 is installed on the mobile platform 2 and is used to screw the spiral anchor rods 6 into the ground. Through the cooperation between the base 1 and the mobile platform 2, the rotary drilling rig 3 can move within the construction area of ​​the group anchor foundation, which makes it easy to install multiple spiral anchor rods 6 into predetermined positions to form a group anchor foundation. During this process, there is no need for construction personnel to come forward and adjust the installation position of each spiral anchor rod 6 one by one.

[0021] The rotary drilling rig 3 mainly includes a mounting base 31, a vertical rod 32, a lifting seat 33, and a drive motor 34. The mounting base 31 is fixedly connected to the mobile platform 2. The vertical rod 32 is fixedly or rotatably connected to the mounting base 31. The lifting seat 33 is slidably connected to the vertical rod 32 along its length. The drive motor 34 is mounted on the lifting seat 33. In the embodiment where the vertical rod 32 is fixedly connected to the mounting base 31, the vertical rod 32 can only be in a vertical or inclined state, without needing to adjust its angle. If the vertical rod 32 is in a vertical state, the rotary drilling rig 3 can only operate on the helical anchor rod 6 that needs to be installed vertically. If the vertical rod 32 is in a specific inclined state, the rotary drilling rig 3 can only operate on the helical anchor rod 6 that needs to be installed at an incline. In the embodiment where the upright 32 is rotatably connected to the mounting base 31, a first driving element 39 for adjusting the inclination of the upright 32 is also provided between the mounting base 31 and the upright 32. The first driving element 39 adopts a hydraulic cylinder, a pneumatic cylinder, a linear motor, an electric push rod, or a rotary motor with an integrated reducer. Taking a pneumatic cylinder as an example, its seat is rotatably connected to the mounting base 31, and the free end of its telescopic rod is rotatably connected to the upright 32. Taking a rotary motor as an example, its housing is fixedly installed on the mounting base 31, and its rotating shaft is connected to the upright 32 for transmission, thereby driving the upright 32 to rotate relative to the mounting base 31 to adjust the angle. The rotary drilling machine 3 can install the spiral anchor rod 6 vertically or at various inclination angles.

[0022] Regarding the motion power of the lifting platform 33 on the upright 32, one technical solution is as follows: A first motor 36 and a winch 37 are installed on the upright 32. The shaft of the first motor 36 is coaxially and fixedly connected to the winch 37, enabling the winch 37 to rotate. A pull rope 38 is wound and connected to the winch 37. The other end of the pull rope 38 is guided by a pulley group at the top of the upright 32 and connected to the lifting platform 33. The pulley group consists of two fixed pulleys installed at the top of the upright 32. When the first motor 36 drives the winch 37 to rotate clockwise and wind the pull rope 38, the pull rope 38 drives the lifting platform 33 and the drive motor 34 to rise along the upright 32. When the first motor 36 drives the winch 37 to rotate counterclockwise and release the pull rope 38, the lifting platform 33 and the drive motor 34 descend along the upright 32. Another technical solution is as follows: A hydraulic device is installed on the upright 32, which drives the lifting platform 33 to move along the upright 32.

[0023] The lifting platform 33 is also equipped with a docking assembly 4, which connects the spiral anchor rod 6 to the power output shaft 35 of the drive motor 34, enabling the power output shaft 35 to drive the spiral anchor rod 6 to rotate together, allowing the spiral anchor rod 6 to be drilled into the ground. (See reference...) Figure 5The docking assembly 4 mainly includes a horizontal slide rail 41, a guide ring 42, a rotating ring 43, a pin 44, and a second driving element 45. The second driving element 45 and the horizontal slide rail 41 are respectively mounted on the lifting seat 33. The outer side of the guide ring 42 is slidably connected to the horizontal slide rail 41, and the inner side of the guide ring 42 is coaxially rotatably connected to the rotating ring 43. There is at least one pin 44 (preferably 2-3), which is fixedly connected to the inner wall of the rotating ring 43. The pin 44 is parallel to the horizontal slide rail 41. A first insertion hole is provided on the power output shaft 35 to engage with the pin 44, and the top of the spiral anchor rod 6 also has a second through hole to engage with the pin 44.

[0024] When the power output shaft 35 is connected to the spiral anchor rod 6, both the drive motor 34 and the connection assembly 4 are positioned above the spiral anchor rod 6. The power output shaft 35 and the spiral anchor rod 6 are coaxial, and the rotating ring 43 is eccentric to the spiral anchor rod 6. As the lifting platform descends, the power output shaft 35 is inserted into the spiral anchor rod 6 from the top, causing the first insertion hole to coincide with the second insertion hole (e.g., ...). Figure 6 Then, the second drive element 45 drives the guide ring 42, the rotating ring 43, and the pin 44 to move together along the horizontal slide rail 41. The pin 44 is inserted into the overlapping first and second insertion holes until the rotating ring 43 and the spiral anchor rod 6 become coaxial. The power output shaft 35 is then connected to the spiral anchor rod 6 (as shown in the image). Figure 7 When the power output shaft 35 drives the spiral anchor rod 6 to rotate, the pin rod 44 and the rotating ring 43 will rotate together with the power output shaft 35, and the rotating ring 43 and the guide ring 42 will rotate relative to each other.

[0025] The storage assembly 5 is mounted on the upright 32 and mainly includes a storage rack 51, a guide rail 52, and a third drive element 53. The guide rail 52 is fixedly connected to the upright 32, and the storage rack 51 is movably mounted on the guide rail 52. The third drive element 53 is used to drive the storage rack 51 to move along the guide rail 52. The storage rack 51 is used to store multiple unused helical anchor bolts 6, typically 3-4 helical anchor bolts 6. During its movement stroke on the upright 32, the storage rack 51 can drive each helical anchor bolt 6 to be positioned below the power output shaft 35 to achieve docking with the power output shaft 35.

[0026] For storage component 5, in one of the technical solutions, see [reference needed]. Figure 8Both the guide rail 52 and the storage rack 51 are arc-shaped. The storage rack 51 is coaxially rotatably connected to the guide rail 52. The storage rack 51 has multiple positioning grooves 56 along the circumferential direction for placing the spiral anchor rod 6. The positioning groove includes a cylindrical groove section and a conical groove section connected from top to bottom. The cylindrical groove section transitions with the rod body of the spiral anchor rod, and the conical groove section is adapted to and inserted into the cone head at the bottom of the rod body, so that the spiral anchor rod is tightly inserted into the positioning groove and the spiral anchor rod is not easy to loosen. The third drive element 53 includes a third motor, a gear 54, and an arc rack 55. The third motor is mounted on the upright 32, and its shaft is coaxially and fixedly connected to the gear 54. The arc rack 55 is coaxially and fixedly connected to the storage rack 51. The gear 54 and the rack mesh with each other. The third motor drives the storage rack 51 to rotate along the guide rail 52 through the gear 54 and the arc rack 55, so that the spiral anchor rod 6 on the storage rack 51 can move to the bottom of the docking assembly 4. After the spiral anchor rod 6 completes docking with the power output shaft 35, the third motor can also drive the storage rack 51 to completely rotate away from the bottom of the drive motor 34, so that the rotary drilling machine 3 can perform downward rotary drilling operations on the anchor rod.

[0027] In another technical solution, both the guide rail 52 and the storage rack 51 are straight. The storage rack 51 is parallel to the guide rail 52 and they are slidably connected along the length direction. The storage rack 51 has multiple positioning slots 56 along the length direction for placing the spiral anchor rods 6. The third driving element 53 is a hydraulic cylinder, a pneumatic cylinder, an electric push rod, or a linear motor. Taking a hydraulic cylinder as an example, its seat is fixedly installed on the guide rail 52, and the free end of its telescopic rod is fixedly connected to the storage rack 51, thereby driving the storage rack 51 to move along the guide rail 52.

[0028] The present invention provides a high-efficiency screw-in device for the construction of group anchor foundations. It is equipped with a storage rack 51 to store multiple spiral anchor rods 6. During the movement of the storage rack 51, each spiral anchor rod 6 can be connected to the power output shaft 35 of the drive motor 34 in sequence. The rotary drilling machine 3 is set on a mobile platform 2 that can move within the construction area of ​​the group anchor foundation. It moves to the working position by itself to drill the spiral anchor rods 6, thereby reducing the reliance on manual intervention and improving the construction efficiency and safety factor of the group anchor foundation.

[0029] During operation, first install the base 1 onto the ground in the construction area of ​​the anchor group, ensuring that the movement range of the mobile platform 2 can completely cover the construction area. Then, install the rotary drilling rig 3 onto the mobile platform 2, and place each spiral anchor rod 6 to be constructed onto the storage rack 51 in sequence (e.g., Figure 1 Based on the construction coordinates of each spiral anchor rod 6, the movement route of the mobile platform 2 is planned in advance. Then, each spiral anchor rod 6 is transported by the storage rack 51 and connected to the power output shaft 35 in sequence with the cooperation of the docking assembly 4 (e.g., Figure 3 This allows each spiral anchor bolt 6 to be drilled into the ground in sequence (e.g. Figure 4Once all the spiral anchor bolts 6 have been installed, the group anchor foundation will be formed.

[0030] It should be noted that after the photoelectric sensor installed on the base detects that the helical anchor has been screwed into the predetermined depth, the drive motor immediately stops drilling the helical anchor. For example, the transmitter of the photoelectric sensor is located inside one of the first tracks, and the receiver of the optical sensor is located inside the other first track. When the light signal emitted by the transmitter is received by the receiver, the drive motor will continue drilling the anchor. When the light signal emitted by the transmitter is blocked by a guide ring larger than the diameter of the helical anchor, the receiver will not receive the light signal, and the drive motor will stop drilling the helical anchor. The operating principle of the photoelectric sensor is existing technology and will not be elaborated here.

[0031] The foregoing description of certain exemplary embodiments of the present invention should not be construed as limiting the scope of protection of the claims. Those skilled in the art will recognize that the described embodiments can be modified in other ways without departing from the spirit and scope of the invention.
