Description

Technical Field

[0001] The present invention relates to the technical field of construction equipment, and more specifically, to a device for efficiently and safely connecting a drill rod to a pile driver. Background Art

[0002] In pile foundation construction, when the project requires deeper holes, a large number of continuous drill rods are used. The current conventional method is: Figure 1 As shown, the pre-drilled process hole is first placed to store the drill rod to be connected. When drilling is required, the pile driver drives to the process hole and puts down the power head to complete the drilling. Then, the power head is lifted to the highest point, and the drill rod is lifted to the bottom of the power head using an auxiliary crane. After the drill rod to be connected is connected with the drill rod below, the crane is removed and the construction personnel are lifted into the air with a hanging basket to complete the connection between the power head and the newly connected drill rod.

[0003] The first method of connecting the drill rod mentioned above requires pre-drilling a process hole. When the construction site is large, multiple process holes may be required. Many pile drivers move slowly in a walking manner, so it takes a long time to connect the drill once, and the overall construction efficiency will be greatly reduced. The second method of connecting the drill rod requires manual high-altitude operation, which has great safety risks. Summary of the invention

The upper end of the rotating end 63 is provided with a lower hinge plate 65. The upper hinge plate 64 and the lower hinge plate 65 are respectively provided with hinge holes. The upper hinge plate 64 and the lower hinge plate 65 are hinged through the hinge 62 of the connecting head 6.

[0044] The lower hinge piece 65 of the fixed end 61 is connected to the lower hinge piece 65 of the rotating end 63 via a hinge 62 , and the fixed end 61 and the rotating end 63 can rotate relative to each other around the hinge 62 .

[0045] Furthermore, a vertical slide groove is provided on the column 2, and the power head 4 is installed in the slide groove and can move up and down.

[0046] Furthermore, the winch 5 is installed on the surface of the drilling rig platform 1, and the free end of the steel wire of the winch 5 passes around the top of the column 2 and is fixedly connected to the top of the power head 4;

[0047] Furthermore, the number of the drill rods 7 is more than two, and the top and bottom of the drill rods 7 are provided with mutually cooperating locking structures, the locking structures are provided with screw holes, and the top and bottom of the drill rods 7 are detachably connected by bolts.

[0048] Furthermore, a flange is provided on the top of the fixed end 61, and a flange structure is provided on the power output shaft of the power head 4, and the flange is connected to the flange structure by bolts.

[0049] Furthermore, the bottom of the piling platform is symmetrically provided with support feet 8 with adjustable heights, and the support feet 8 are composed of a pad and a cylinder.
