Description

Technical Field

[0001] This invention relates to the field of pile drilling technology, and in particular to a disengagement mechanism for a multi-head pile drilling rig. Background Technology

[0002] In existing foundation pile projects, foundation pile drilling rigs are often used for drilling. Foundation pile drilling rigs mainly consist of a machine body and a drill rod for drilling. Usually, the drill rod is installed on the machine body so that the drill bit of the drill rod is vertically downward and rotates to drill a hole in the ground. After drilling is completed, the drill rod needs to be separated from the ground. However, since the ground of foundation piles is mostly concrete or soil, it is difficult to separate the drill rod and it is very likely to damage the drilling rig. Summary of the Invention

[0003] The purpose of this invention is to provide a multi-head drilling rig detachment mechanism for foundation piles, which facilitates the detachment of the drilling rig from the foundation pile after drilling is completed.

Connecting plates B and C are fixedly disposed on the upper part of the support column and below the connecting plate A, with the connecting plate C located below the connecting plate B. A housing is disposed outside the support column and between the connecting plates B and C. A water spray pipe is disposed at the outer end of and through the connecting plates B and C. A pulley A is fitted over the water spray pipe, with the lower end of the pulley A extending into the connecting plate C. An electric cylinder is fixedly disposed on and through the connecting plate C, with the output end of the electric cylinder extending upward through the connecting plate B and fitted with a pulley B. A belt is fitted over the pulleys B and A.

[0010] To facilitate the detachment of the drill bit from the pile, the detachment assembly includes a demolding sleeve fitted over the water spray pipe, and the demolding sleeve penetrates the connecting plate B and the connecting plate C; a sleeve is fitted over the demolding sleeve, the upper end of the sleeve is fixedly connected to the lower end face of the connecting plate B, and the lower end of the sleeve is fixedly connected to the upper end face of the connecting plate C.

[0011] To facilitate drill bit position adjustment, the drive assembly includes a gear fixedly mounted on the upper surface of the top plate, with the rotating shaft passing through the gear; a toothed block is provided on one side of the gear, and a motor B is connected to one side of the toothed block.

[0012] A square plate is horizontally arranged on the drive assembly, and the rotating shaft passes through the square plate.

[0013] Due to the adoption of the above technical solution, the present invention has the advantages of simple structure and convenient use. The device can make the drill bit easily detach from the foundation pile after the drilling machine has completed drilling. By setting up a water spray pipe and a detachment component, it is ensured that the drill bit will not generate heat due to friction during drilling, thereby avoiding damage to the drilling machine.
