[0002] When using a rotary drilling rig, the drilled pile hole needs to be enclosed according to different terrains. Usually, a water pipe is placed at the upper end of the pile hole to inject water into the pile hole. On the one hand, the water can cool the rotary head, and on the other hand, it can keep the soil layer evenly stressed and avoid the occurrence of hole collapse.

[0019] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application (for the convenience of description and understanding, the following is Figure 2 All other embodiments obtained by persons of ordinary skill in the art without creative work shall fall within the scope of protection of this application.

[0020] See also Figure 1-5 The present application provides a technical solution for a water supply device for a rotary drilling rig: a water supply device for a rotary drilling rig, comprising a power head and an I-frame. The power output end of the power head is connected to the I-frame. The I-frame is vertically arranged, and a through hole is opened in the middle thereof to accommodate the drill rod of the rotary drilling rig. The outer side of the I-frame is divided into four spaces by four reinforcing ribs 3, two of which are provided with winding assemblies 5, and the other two spaces are respectively provided with a control cabinet 18 and a solar panel 16. A support plate 4 is provided on the upper surface of the reinforcing rib 3, and an inner cylinder 13 is provided on the support plate 4. The outer side of the inner cylinder 13 is rotatably connected to the outer water tank 10 through two sealed bearings 12. A water inlet pipe 11 and a fixed plate 22 are respectively provided on the outer side of the outer water tank 10. The fixed plate 22 is connected to the power head through a limit plate. Two water outlet pipes 9 are provided on the inner side of the inner cylinder 13, and the water outlet pipes 9 are located above the winding assembly 5.

[0021] Specifically, the limit plate is fixed on the outer shell of the power head. Through the cooperation between the limit plate and the fixed plate 22, the outer water tank 10 can be controlled to remain stationary, while the I-frame, winding assembly 5, solar panel 16, control cabinet 18 and inner cylinder 13 can rotate with the drive of the power head.

[0022] More specifically, the I-frame is mainly composed of a top plate 14, a sleeve 1 and a bottom plate 2. The top plate 14 and the bottom plate 2 are both disc-shaped, and the top plate 14 and the bottom plate 2 are connected by the sleeve 1. The bottom plate 2 is located in the space of the winding assembly 5 and is provided with a hole 17.

[0023] A water pipe is wound around the coil assembly 5, one end of which is connected to the water outlet pipe 9, and the other end of which passes through the hole 17 on the base plate 2 and is fixed to the drill rod, thereby facilitating the water inside the outer water tank 10 to be transported to the drill rod and into the pile hole, ensuring the stability of the pressure on the inner wall of the pile hole.

[0024] Furthermore, the winding assembly 5 is mainly composed of a winding wheel 6, a side plate 7 and a servo motor 8. Two side plates 7 are installed on the I-frame through fasteners. The two side plates 7 are connected to the winding wheel 6 through a rotating shaft. The servo motor 8 is arranged on one side of the side plate 7, and the power output end of the servo motor 8 is connected to the rotating shaft on the winding wheel 6.

[0025] In this arrangement, the drill rod rotates under the drive of the power head to drill a hole. When the drill rod moves downward, the servo motor 8 drives the reel 6 to rotate, thereby making the water pipe longer, making it easier to supply water to the pile hole and ensuring stable pressure in the pile hole.

[0026] Furthermore, the two coiled assemblies 5 are symmetrically arranged with respect to the reinforcing rib 3 .

[0027] Furthermore, the solar panel 16 is connected to the I-frame via the support base 15 .

[0028] Furthermore, a control panel 19 is provided on one end face of the control cabinet 18 , and the interior of the control cabinet 18 is divided into two spaces by a partition, and a controller 20 and a battery 21 are provided in each space.

[0029] Specifically, the solar panel 16 can absorb ultraviolet rays from the sun and transmit them to the battery 21 through the controller 22 for storage, thereby providing power support to the servo motor 8 .

[0030] like Figure 5 As shown, the power head is mainly composed of a sliding frame, hydraulic parts, shock absorbers, a driver and a collision body. A sliding frame is provided on one side of the driver, and a collision body is provided at the power output end of the driver. The collision body can rotate with the driver and drive the I-frame to rotate. A shock absorber is provided on the upper surface of the driver, and two hydraulic parts are provided on the rear side of the shock absorber. The inside of the driver is slidably connected to the drill rod, and the driver can drive the drill rod to rotate.

[0031] During use: the top plate 14 of the I-frame is fixedly connected to the collision body of the power head by bolts, and the limit plate is fixed to the outer shell of the power head by bolts to prevent the outer water tank 10 from rotating. When the power head drives the rotating rod and the collision body to rotate, the I-frame is driven to rotate, thereby ensuring that the I-frame and the rotating rod rotate in the same direction.

[0032] The fixed plate 22 on the outside of the outer water tank 10 is limited by the limit plate on the power head, and then the piling operation is carried out. At the same time, the power head drives the I-frame and the drill rod to rotate in the same direction to avoid the water pipe being entangled on the drill rod and causing an accident. While the drill bit is digging, the servo motor 8 drives the reel 6 to rotate, so that the water pipe wrapped around the reel 6 is extended to ensure the stability of the water supply in the pile hole. The solar panel 16 can absorb sunlight and store electricity in the battery 21 through conversion by the controller 20 to meet the power needs of the device.

[0033] It is worth noting that the input end of the controller 20 mentioned in the present application is electrically connected to the output end of the solar panel 16 , and the output end of the controller 20 is electrically connected to the input end of the winding assembly 5 through the control panel 19 .

[0034] Although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
